Full textAbstract:
This study was conducted to evaluate the antibacterial effect of the aqueous and Methanolic extracts of Aloe Lanata and Aloe Vacillanis. Using agar diffusion method, three different concentrations of Aloe extracts were evaluated on Staphylococcus aureus, Escherichia. coli, Pseudomonas aeruginosa, and to compare the effectiveness of extracts with some antibiotics (Ampicillin: Amp, Erythromycin: Erytho, Gentamycin: Genta).The extracts showed that there was a different effect on the bacterial species according to the type and concentration of the plant extract as well as the inhibitory response to the bacterial species. The aqueous and alcoholic extract of A. lanata is more potent than A. vacillanis extract. In comparison to the type of extract, the alcoholic extract of A. lanata was more effective than the aqueous extract, while the aqueous extract of the A. vacillanis showed higher efficacy than the alcoholic extract. Both extracts had the most substantial effect on both E. coli and P. aeroginosa and were less effective on S. aureus. Antibacterial efficacy of studied plant extracts showed better efficacy than the antibiotic (Ampicillin, Erythromycin) on Staphylococcus aureus and E. coli.

Objectives: Phytochemical constitutents and antimicrobial property of the aqueous extract of the gel and leaf extract on some pathogenic microorganisms. The phytochemical determined include Tannins, Saponins, Flavonoids and Alkaloids. The gel of Aloe vera extract had its highest antibacterial activity on B. subtilis (23.33±0.88) and highest antifungal activity on C. albicans (16.00±2.31). While the leaf of Aloe vera extract had its highest antibacterial activity on B. substilis and S. aureus (21.33±0.88) and highest antifungal activity on C. albicans (21.00±3.22). Comparatively, the Aloe vera gel extracts showed better antimicrobial activity than the Aloe vera leaf extracts against the pathogenic microorganisms in the study. The antimicrobial activities of Aloe vera gel and leaf extracts were compared to those of orthodox antibiotics (Ciprofloxacin and Ketoconanzone). From the results, the Aloe vera plant (gel and leaf) extracts showed better antimicrobial activity than the orthodox antibiotics, therefore, Aloe vera plant extracts have shown to have the ability to overcome antibiotics resistances amongst microorganisms. Results of the study on the gel and leaf extracts of Aloe vera indicates its potential as a source of chemotherapuetic agent that may be useful in medicine.

Full textAbstract:
This study aims to determine the effect of Aloe vera extract in reducing formaldehyde levels in salted squid and determine the organoleptic characteristics of salted squid after being given Aloe vera extract. This study used a completely randomized design (CRD) with 4 treatments and 6 replications: P0 (0% Aloe vera extract), P1 (10% Aloe vera extract), P2 (20% Aloe vera extract), and P3 (30% Aloe vera extract). Data were analyzed by using an analysis of variants at a significant level α = 0.05 followed by Duncan's Test. The average formalin content before given aloe vera extract in P0, P1, P2, P3 was 3.65 mg / L, 4.08 mg / L, 4.09 mg / L, 3.96 mg/ L, respectively and after being given aloe vera extract was 2.75 mg/L, 2.58 mg / L, 1.63 mg / L, 2.82 mg / L, respectively. Administration of Aloe vera extract showed a significant reduction of formaldehyde levels in salted squid (p<0.05). Moreover, it was affecting the quality of salted squid in terms of color, aroma, and texture. It can be concluded that the administration of 20% Aloe vera extracts effective for reducing the formaldehyde levels, improve the quality of color, aroma, and texture in salted squid.

Full textAbstract:
ackground and aims: Natural products, especially plant extracts, have opened up great opportunities in the field of drug progress due to their chemical variety. The genus Aloe has long been used for medicinal uses in countless parts of the world. This study was designed to investigate the phytochemicals and anti-cancer capabilities of Aloe rubroviolaceae, Aloe vera and Aloe sabaea flowers. Materials and Methods: The methanolic extracts of three types of plants traditionally used in Yemen to treat a variety of diseases have been tested in vitro for their potential anticancer activity on different human cancer cell lines. The cytotoxic activity of the methanolic extracts of tested plants was determined using eleven strains of human cancer cells, namely: MCF-7 (breast cancer), PC-3 (prostate cancer), HEP-2 (human epithelial carcinoma), MNFS-60 (myelogenous leukemia), CACO (intestinal cancer), A-549 (lung adenocarcinoma), HeLa (cervical cancer), RD (rhabdomyosarcoma),HepG2 (hepatocellular carcinoma), HCT-116 (colon cancer), and CHO-K1 (Chinese hamster ovary). A colorimetric sulforhodamine B assay was used to evaluate the in vitro cytotoxic activity of different extracts. Growth inhibition of 50% (IC50) for each extract was calculated from the optical density of treated and untreated cells. Doxorubicin, a broad-spectrum anticancer drug was used as a positive control. Results: More interesting cytotoxic activity was observed for Aloe vera extract more than Aloe sabaea and Aloe rubroviolaceae, extract. Conclusions: This study provides a preliminary screening for anti-proliferative activity of various Aloe species flowers extracts on different cancer cell lines. Different extracts of Aloe species significantly inhibit the growth of various cancer cell lines in a concentration-dependent manner. Further investigations are required to understand the possible mechanism(s) of action of these extract on various cancer cells and isolation of active phyto-chemicals.

This study was conducted to evaluate the effect of different extracts of Aloe Vera gel in alloxan induced hyperglycaemic mice.Three different extracts of Aloe Vera gel (dried extract, ethanolic extract and fresh raw extract) were orally administered at 300 mg/kg body weight for 28 days. The fasting blood glucose level was estimated both in normal and alloxan induced hyperglycaemic mice. It was found that, when compared with the control, there was a significant reduction in blood glucose level in all three experimental groups. Ethanolic and fresh raw gel extracts were more effective than the dried extract. The extracts produced similar results when compared with gliclazide. It can be concluded that, the administration of Aloe Vera gel extract significantly decreases blood glucose level in hyperglycaemic mice. Aloe Vera gel can therefore be a natural remedy and a cost effective resource for the management of diabetes.Bangladesh Med J. 2015 May; 44 (2): 61-66

Full textAbstract:
The utilization of cuttings remains a prevalent method for vegetative propagation in various plant species. Synthetic rooting hormones have conventionally been employed to enhance the rooting process; however, their high cost and potential environmental risks have necessitated the exploration of natural alternative compounds. In this study, the efficacy of natural plant extracts (pure honey, aloe extract, willow extract, moringa extract, and cinnamon powder) and synthetic auxin derivatives (indole-3-butyric acid and α-naphthaleneacetic acid) at a concentration of 2000 ppm was compared for their influence on rooting and vegetative growth of snowbush (Breynia disticha) cuttings, a significant ornamental and medicinal shrub. Results demonstrated that while the synthetic hormones produced the highest survival percentages and root number, the roots were consistently short, thick, friable, and largely void of secondary roots. Conversely, the alternative natural plant extracts, particularly aloe extract, exhibited promising outcomes, showcasing good rooting percentage and root number, significantly increased root length, and fresh and dry root weight. Furthermore, aloe extract demonstrated the potential to enhance shoot length and alter the chemical constituents of the cuttings. The highest values of total phenols and nitrogen percentage were recorded with cuttings treated with indole-3-butyric acid, followed by cuttings treated with aloe extract. While using aloe extract, we recorded the highest values of total carbohydrates, phosphorus, and potassium percentages. Notably, the highest endogenous levels of indole acetic acid and gibberellic acid, along with the lowest abscisic acid concentration in cutting tissues, were associated with the highest rooting percentage observed with indole-3-butyric acid, followed by the use of aloe extract. We hypothesized that natural plant extracts, specifically aloe extract, have potential as a viable alternative for synthetic auxins in promoting successful rooting and vegetative growth in snowbush cuttings. Further research is warranted to explore the underlying mechanisms and optimize the application of these natural compounds in vegetative propagation techniques.

Full textAbstract:
Impaired kidney function is associated with structural damage that usually cause negative effect to both human and animal health. It is associated with many complications such as anaemia, cardiovascular disease, and cognitive impairment. We evaluated the effect of aqueous and methanol extracts of Aloe vera (AV) on ethanol-induced kidney and brain injury in mice. Thirty mice were assigned to six groups (n=5) and received distilled water (control), 20% ethanol (negative control), (50 and 100) mg/kg methanol extract of Aloe vera plus ethanol, and (25 and 50) mg/kg aqueous extract of Aloe vera plus ethanol respectively for eighteen days. The mice were euthanized thereafter, and kidney function test was evaluated from the serum while oxidative stress markers were evaluated from the brain homogenate. One half of each brain was processed for light microscopy. The result showed that pretreatment with methanol and aqueous extracts of Aloe vera significantly reduced (p<05) the serum urea level relative to the ethanol-treated mice. The methanol extract (50mg/kg) and aqueous extract (25mg/kg) of Aloe vera significantly elevated (p<05) catalase activity relative to the ethanol-treated mice. Both the aqueous and methanol extracts of Aloe vera significantly reduced (p<05) malondialdehyde activity compared to the ethanol-treated mice. The cerebellum and cerebrum of the control mice and the mice pretreated with both the methanol and aqueous extracts of Aloe vera at 50mg/kg showed normal neurons. Conclusively,aqueous and methanol extracts of Aloe vera regulated serum urea levels, significantly increased brain catalase and reduced glutathione activities in ethanol-treated mice. It also prevented lipid peroxidation and neurodegeneration.

Full textAbstract:
The Increasing case of antibiotic resistance encourages a new action that is the combination plant extracts and antibiotics. Aloe vera leaf skin (Aloe vera (L.) Burm f.), contains phenols, flavonoids and anthraquinones that act as antimicrobials. The aim of research is to determine the value of FICI (Fractional Inhibitory Concentration Index) combination of ethanol extract of Aloe vera leaf skin (Aloevera (L.) Burm f.), and chloramphenicol against pathogenic bacteria. The determination of MIC (Minimum Inhibitory Concentration) value of ethanol extract for Aloe vera leaf skin (Aloe vera (L.) Burm. F.) and chloramphenicol use disc-paper diffusion method. The combination solution is created by a ratio of 1: 1 volumes from the every MIC values. The determination of FICI values was analyzed by descriptive. The combination of Aloe vera leaf skin extract (Aloe vera (L.) Burm. F.) and chloramphenicol are used for Salmonella typhi bacteria which are 12.5mg / ml and 8 μg / ml, and for Bacillus subtilis bacteria is 2.5 mg / ml and 4 μg / ml resulted in inhibit zone 7.77 ± 0.25 and 7.83 ± 0.36. The combination of FICI value is 2 and it has indifference characteristics (not different) when the researcherd compared between single extract and single chloramphenicol. Aloe vera leaf skin ethanol extract (Aloe vera (L.) Burm. f.) and chloramphenicol may inhibit the growth of Salmonella typhi and Bacillus subtilis bacteria and both of the combinations show indifference characteristics of FICI 2 values. Keywords: FICI, Aloe Vera, Antibacterial, Chloramphenicol.

Full textAbstract:
Antibiotics are empirically used as drugs to treat bacterial infections, but the irrational use of antibiotics causes bacterial resistance to certain antibiotic regimens, therefore solutions are needed to explore alternative drugs. This study aims to explore medicinal plants that are able to inhibit Pseudomonas aeruginosa bacteria that are resistant to quinolones and cephalosporins. The method used is descriptive observational and antibacterial activity test of plant extracts using the well diffusion method. Three plant extracts were used, binahong extract (Andredera cordifolia), tomato fruit extract (Lycopersicon esculentum), and aloe vera extract (Aloe vera). The results showed that only tomato extract inhibited Pseudomonas aeruginosa bacteria with a strong category, while binahong and aloe vera extracts could not inhibit the test bacteria. It was concluded that tomato fruit extract might be an alternative as a medicinal plant because it was able to inhibit P. aeruginosa resistant to quinolones and cephalosporin antibiotics.

Full textAbstract:
A comparative survey to determine the antibacterial potency of black soap formulated with Aloe vera and the Aloe vera extracts against some clinical pathogens (Staphylococcus aureus, Streptococcus pyogenes and Pseudomonas aeruginosa) of skin origin was carried out using agar "well" diffusion method. The Aloe vera formulated black soap and the Aloe vera extracts shows appreciable antibacterial potentials at all the concentrations (10%, 30%, 50% and 70%) used against the test organisms. The highest activity of 20.0 mm was recorded against S. aureus at the highest concentration of 70% used for the Aloe vera formulated soap and no activity was observed at the lower concentration against Ps. aeruginosa. Both the Aloe vera Gel and ethanolic leaf extracts recorded the highest activity of 18.0 mm against Ps. aeruginosa at the highest concentration of 70% used; no activity was recorded against S. aureus at lower concentrations used for both extracts and also no activity was observed against S. pyogenes for the Aloe vera ethanolic leaf extract. The MIC and MBC survey of the Aloe vera extracts and the formulated soap from Aloe vera indicates high antibacterial potentials against the test organisms except for the ethanolic leaf extract that fails to show any activity against S. pyogenes. The phytochemical survey of the extracts also revealed the presence of many important bioactive compounds including saponins, tannins and anthraquinones. These surveys have given a pointer to the possibility of using Aloe vera extracts for the formulation of skin care and skin remedies.

Full textAbstract:
CoordenaÃÃo de AperfeÃoamento de Pessoal de NÃvel Superior<br>The oral mucosa is one of the human body areas most frequently traumatized and usually presents traumatic ulcers. There are different treatment choices among which both professionals and patients may follow in order to treat oral ulcerations, for instance, formulations from plants extract among other natural products. The use of phytotherapics has a long history of success, however the associated use of substances still has poor scientific background. The aroeira-do-sertÃo (Myracrondruon urundeva AllemÃo) and Aloe vera (Aloe barbadensis Miller) have anti-ulcerogenic and anti-inflammatory proven activity when used as isolated substances and have been largely prescribed by health care professionals. The goal of this study was to evaluate the combined use of the aqueous extract of aroeira (10%) with the dry extract of aloe vera (40%) on the treatment of traumatic ulcers, as well as its toxicity. Traumatic ulcers were surgically created on the oral mucosa of Wistar rats and further exposed to the test solution containing both aroeira e aloe vera, twice a day. The animals from test and control grups were sacrificed by euthanasia after 01, 05 and 10 days. The oral ulcers were measured and histologically evaluated. Their corporeal mass were compared and a hematological analysis performed. Stomach, kidneys, liver and spleen were removed and microscopically investigated for signs of toxicity. According to the results, the combined solution of aroeira and aloe vera did not present systemic toxicity, neither had any influence on the ulcers healing performance, despite having reduced its initial growth.<br>A mucosa bucal à uma das Ãreas mais traumatizadas do organismo, podendo apresentar Ãlceras traumÃticas com frequÃncia.

A utilizaÃÃo de fitoterÃpicos tem uma longa histÃria de sucessos, porÃm, o uso combinado de substÃncias ainda apresenta escassa referÃncia cientÃfica. A aroeira-do-sertÃo (Myracrodruon urundeuva AllemÃo) e a Aloe vera (Aloe barbadensis Miller) tÃm comprovada aÃÃo antiulcerogÃnica e anti-inflamatÃria quando usados isoladamente e sÃo amplamente indicados por profissionais da saÃde. O objetivo desse estudo foi avaliar a aÃÃo conjugada do extrato aquoso de aroeira (10%) e extrato seco de Aloe vera (40%) no tratamento de Ãlceras traumÃticas e sua toxicidade. Ãlceras traumÃticas foram realizadas cirurgicamente em mucosa de ratos Wistar e expostas a uma soluÃÃo teste contendo aroeira e aloe, aplicadas duas vezes ao dia. Os animais dos grupos controle e teste sofreram eutanÃsia em 01, 05 e 10 dias e tiveram suas Ãlceras medidas e avaliadas histopatologicamente. Foi tambÃm realizada uma comparaÃÃo da massa corpÃrea e uma anÃlise hematolÃgica em todos os animais. EstÃmago, rins, fÃgado e baÃo foram analisados por microscopia Ãtica para avaliaÃÃo de parÃmetros de toxicidade. De acordo com os resultados, a soluÃÃo conjugada dos dois fitoterÃpicos nÃo apresentou toxicidade sistÃmica, nem influenciou na cicatrizaÃÃo das Ãlceras, apesar de ter reduzido o seu crescimento inicial.

Full textAbstract:
Aloe mites are herbivores of the genus Aloe (ALOACEAE) and are associated with hyperplastic growth in various aloe species, but the biochemistry of this interaction is poorly understood. In an effort to characterize plant defense responses to herbivory in the genus Aloe, a salivary extract was isolated from aloe mites (Aceria aloinis Keifer) and its bioactivity was tested using a hypocotyl elongation assay. Subsequently, Aloe striata plants were treated with jasmonic acid (JA), salicylic acid (SA), and the mite salivary extract. Using water and methanol, compounds of different polarity were extracted from aloe tissues that had been frozen and crushed at 4, 12, and 24h after treatment. Extracts were analyzed by HPLC and three compounds were found. One of these compounds was SA (mean concentration of 4µg/mL), and this is the first time that this aloe species has been found to produce SA. Two additional peaks of unknown identity were observed in JA- and SA-treated plants. These results suggest that A. striata may in fact undergo a JA-mediated change in secondary metabolism as part of a plant defense response.

Magister Scientiae - MSc (Chemistry)<br>Global climate change and geographical differences are two major parameters known to
have, either, direct or indirect influence on the production of secondary metabolites in plants,
which in-turn may affect the quality and/or quantity of the overall metabolites. The primary
purpose of this thesis was to evaluate the phytochemistry of the whole leaf of Aloe succotrina
Lam. spp. - a South African native plant - through a chromatographic spectroscopic
approach-against available data accumulated for the cultivated population. Preliminary
screening of the crude extracts i.e. HEX, DCM and EtOAc on TLC aluminium plates precoated
with silica gel 60 F254 followed by various chromatographic separation, led to the
isolation of five known compounds: ?-sitosterol (1) and two anthrone-C-glycosides (2 and 5),
including two coumarin derivatives-the aglycone (3) and glycoside derivative (4). Notably,
apart from 5 and 2, the accumulation of 1, 3 and 4 in A. succotrina Lam. spp. is reported for
the first time. Structural elucidation of the individual compounds was achieved by extensive
spectroscopic analysis i.e. MS, IR, 1H and 13C-NMR spectroscopy and in some cases
comparison to the literature. A comparative HPLC chromatogram of the crude MeOH extract
of the leaves of A. succotrina Lam. was developed for qualitative (and quantitative)
identification of the active metabolites, which could be realized by VWD with detection at
290 nm.

2,0x3,0cm mold, after making the injuries were applied the solution to be tested, Aloe
vera and the positive and negative controls Results: regarding angiogenic activity
observed If through the images that 80% of MCAs which was used Aloe vera was the
formation of thicker blood vessels and in greater quantities, but there was no difference
significant when compared to the positive control. Regarding scar activity results in
macroscopic evaluation showed that 100% of the test group mice showed a complete
closure of the lesions on the 21st day of the experiment while only 40% of the control
group had complete closure. But when the Tukey test (p> 0.05), there was no statistical
difference. Demonstrating how the scar activity of Aloe vera is the same as
Regederm® you already have scientific evidence in wound healing. Conclusion: Aloe
vera presented healing activity equal to the positive control, the MCA presented
angiogenic activity equal to the positive control, with formation of new vessels, it was
easy to apply and handling, conclusion themselves with what the Aloe vera extract or
pro components -angiogênicos isolates may have potential pharmaceutical
applications for wound treatment.<br>Objetivo: Avaliar a influência do Aloe vera (Aloe barbadensis) na atividade angiogênica
e cicatricial Métodos: estudo experimental onde se utilizou 120 ovos férteis de galinha

discos de papel de filtro, veiculando 3 µL da solução a ser testada (extrato glicólico de
aloe vera a 10%), e os devidos controles, foram depositadas diretamente sobre a
Membrana Corioalantóide-MCA de forma cuidadosa para avaliação da atividade
angiogênica do Aloe vera. A atividade cicatricial foi avaliada utilizando 15 ratos
saudáveis, da espécie Rattus norvegicus albinus, através da criação de uma lesão
no dorsos de cada rato utilizando um molde do tamanho retangular 2,0x3,0cm, após
a confecção da lesão eram aplicadas a solução a ser testada, Aloe vera e os controles
positivo e negativo Resultados: com relação a atividade angiogênica observou se
através das imagens que 80% das MCAs onde se utilizou o Aloe vera houve formação
de vasos sanguíneos mais grossos e em maior quantidade, porém não apresentou
diferenças significativas quando comparada ao controle positivo. Com relação a
atividade cicatricial os resultados na avaliação macroscópica demonstraram que
100% dos ratos do grupo teste apresentaram um fechamento completo das lesões no
21º dia do experimento enquanto que apenas 40% do grupo controle apresentavam
fechamento completo. Porém quando aplicado o teste de Tukey, (p>0,05), não houve
diferença estatística. Demostrando assim que a atividade cicatricial do Aloe vera é
igual à do Regederm® que já possui comprovação cientifica na cicatrização de feridas.
Conclusão: o Aloe vera apresentou atividade cicatrização igual ao controle positivo,
na MCA apresentou atividade angiogênica igual ao controle positivo, com formação
de novos vasos, foi de fácil aplicação e manuseio, Concluindo -se com isso que o
extrato de Aloe vera ou componentes pró-angiogênicos isolados podem ter potencial
para aplicações farmacêuticas para o tratamento de feridas.

Previous issue date: 2016<br>Diversas culturas se baseiam na utilização de plantas para o tratamento de doenças. Plantas do gênero Aloe vem sendo utilizadas a séculos na medicina tradicional para cicatrização de feridas, como agente antibacteriano, como laxante e até mesmo para o tratamento do câncer. O extrato do parênquima clorofiliano (EPC) da Aloe barbadensis Miller é excretado quando a folha é cortada ou quebrada, este líquido de cor amarelada é rico em antronas, cromonas e seus derivados. Estudos com compostos isolados do EPC, aloína e Aloe emodina, mostram uma promissora atividade antitumoral dos mesmos. A incidência do melanoma cutâneo vem aumentando nos últimos anos, o que gera uma grande preocupação, uma vez que esse câncer é altamente agressivo apresentando alta possibilidade de metástase. Neste trabalho o EPC foi padronizado por HPLC, apresentando 5,6% em massa seca do isômero aloína B. A citotoxicidade foi avaliada do EPC em linhagens de fibroblastos L-929, assim como o efeito do EPC sobre a viabilidade, proliferação, morfologia e migração de duas linhagens de melanoma (SK-MEL-28 e B16-F10). De acordo com a ISO 10993-5, concentrações superiores a 185 µg·mL-1 de EPC são citotóxicas (decréscimo na viabilidade maior que 30%), sendo esse valor maior que o valor de IC50 de ambas as linhagens de melanoma, 125 e 165 µg·mL-1 para a SK-MEL-28 e B16-F10, respectivamente. Análise morfológica mostrou ponto de alta fluorescência, indicando uma reorganização dos filamentos de actina presentes no citoesqueleto. O resultado do ensaio de migração para ambas linhagens de melanoma mostrou que o EPC é mais eficaz em inibir a migração do melanoma humano SK-MEL-28. Células endoteliais (HUVEC) foram expostas ao EPC e os parâmetros de viabilidade celular, proliferação, morfologia, migração e formação de tubos foram avaliados. O EPC inibiu a migração de HUVECs mesmo em concentrações que não apresentaram efeito de decréscimo na atividade metabólica e proliferação celular. Pôde-se observar a retração das fibras de estresse em células tratadas com as concentrações de 10 e 100 µg·mL-1 de EPC. A formação de tubos em células endoteliais foi inibida na maior concentração testada (100 µg·mL-1), contudo ainda se observa a formação de brotos vasculares. Em suma o EPC proveniente de Aloe barbadensis Miller causou um decréscimo na viabilidade e proliferação celular assim como uma diminuição da capacidade de migração e alterações morfológicas de células de melanoma e endoteliais, influenciando também na formação de tubos vasculares por células endoteliais.<br>Abstract : Several cultures are based on the use of plants for the treatment of diseases. Plants of the genus Aloe has been used for centuries in traditional medicine, in wound healing, such as antibacterial agent, laxative and even for the treatment of cancer. The chlorophyll parenchyma extract (EPC) from Aloe barbadensis Miller is excreted when the sheet is cut or broken, this yellowish liquid is rich in anthrones, chromones and their derivatives. Studies on compounds isolated EPC, aloin and Aloe emodin, showed promising antitumor activity. The incidence of melanoma has increased in recent years, creating a great concern, since this cancer is highly aggressive and presents high possibility of metastasis. In this work the EPC was standardized by HPLC, showing 5.6% of dry weight of aloin B isomer. The EPC cytotoxicity was evaluated on fibroblast L-929 cell line, as well as the effect of EPC in cell viability, proliferation, morphology alterations and migration on two melanoma cell lines (SK-MEL-28 and B16-F10). According to ISO 10993-5, concentrations higher than 185 µg·mL-1 EPC are cytotoxic (decrease in viability was greater than 30%), this value being higher than the IC50 value of both melanoma cell lines, 125 and 165 µg·mL- 1 to SK-MEL-28 and B16-F10, respectively. Morphological analysis showed high fluorescence spots, indicating a reorganization of actin filaments present in the cytoskeleton. The result of the migration test for both melanoma cell lines showed that the EPC is more effective to inhibit the migration of human melanoma SK-MEL-28. Endothelial cells (HUVEC) were exposed to the EPC and parameters of cell viability, proliferation, morphology alterations, migration and tube formation was evaluated. The EPC inhibited HUVEC migration even at concentrations that has not shown effect in decrease of metabolic activity and cellular proliferation. It was observed the decrease of stress fibers in cells after treated with concentrations of 10 and 100 µg·mL-1of EPC. The tube formation on endothelial cells was inhibited at the highest concentration tested (100 µg·mL-1), however it was still possible to observe the formation of vascular sprouts. In short, the EPC from Aloe barbadensis Miller caused a decrease in cell viability and proliferation as well as reduced migration ability and morphological changes on melanoma and endothelial cells, also influencing the vascular tube formation by endothelial cells.

Los esfuerzos en investigación científica están dirigidos en la búsqueda de nuevos tratamientos que puedan minimizar el deterioro por corrosión de los materiales metálicos, ya que es un problema que en el sector industrial viene presentándose en los últimos años, la corrosión tiene un impacto en altos costos en mantenimiento y reparación industrial en el que involucra el uso de aceros como el AISI-1045 grado estructural, el acero 4140 grado herramienta y el acero AISI-8620 grado maquinaria, estos aceros se desempeñan en ambientes agresivos durante su servicio. Ante estos problemas y la necesidad de proteger los aceros en la industria para un mejor aprovechamiento de su vida útil, se utilizaron 2 inhibidores ecológicos biodegradables capaces de inhibir el deterioro químico de los materiales metálicos los cuales fueron el GEL de Aloe-Vera y el extracto etanólico de Morinda Citrifolia.<br>It is well known that metallic materials could be corroded during their service due to their exposed environment, which is considered as one of the main problems in the manufacture industry that has been occurred in the last century. Corrosion can cause from loss of human lives until spill of economic, in addition to failure in electrical power plants, serious disasters on bridges, collapsing concrete buildings, immediate deterioration of ships, leaking pipelines, mechanical damage failure, surface alteration properties, another sever damages in infrastructure, in addition to this damage, corrosion also causes irreversible impact on the environment as air or soil pollution and global warming.
In order to reduce the damage caused by corrosion mechanism, different kind of methods, procedures and/or treatments have been developed, among which the use of corrosion inhibitors (IC), where a classification as organic inhibitor has been existed, this creates a stack of molecules to form multi-layer between the metal material and the corrosive media.
Therefore, in this research the efficiency of inhibition (EI) of two biodegradable natural liquid-extracts is evaluated in an aqueous solution of hydrochloric acid (HCl) 1 Molar, also IC molecules are considered as a new alternative capable of inhibiting the chemical deterioration of any metallic material and consequently minimize the corrosion problems above describe.
The liquid inhibitors studied here were; extracts from Morinda Citrifolia leaves (ethanol extracted) and GEL (aqueous extracted) leaves of Aloe-Vera, commonly known as Sabila. These liquid-extracts were added at different volume ratios to acid (HCl-1M) media. Their performance as corrosion inhibitor is then monitored and evaluated by electrochemical techniques as polarization TAFEL (Ecorr vs. I) and spectroscopy Impedance electrochemical (EIS, Zreal vs. Zimag). From EIS parameters, the EIS data were analyzed by a correlation with an appropriate equivalent electric circuit (EEC) and the TAFEL data were used to determined EI%, whereas the thermodynamic analysis by using the adsorption isotherms the type of inhibitor was classified as mixed.
Additionally, Optical Microscopy images were obtained before and after undergoing industrial steels in contact with the corrosive solution without extracts from the leaves of Morinda Citrifolia and Aloe-Vera that serve as inhibitors. On the other hand, properties such as contact angle, viscosity and surface tension of the natural organic molecules were obtained in order to determine the wettability and the mechanism of adsorption of organic molecules (natural liquid extracts) with the surface of the steels exposed to corrosive environment.
According to the EIS results of industrial steels (AISI 1045, 4140 and 8620) studied here, they had pitting corrosion after hours exposure in HCl-1M. Meanwhile, the use of GEL extracted from Aloe-Vera (Aloe) demonstrated to be corrosion inhibitor efficiencies, EI~ 75% at 10 ml to 1045 steel, 4140 steel EI~ 70% at 16 ml and 8620 for steel EI~ 30% from 2ml. Meanwhile the ethanol extract of Morinda Citrifolia proved to be an excellent inhibitor capable to minimize the pitting corrosion process from 4 or 6 mL of its volume concentration (steel 1045, EI> 93.1%, steel 4140 and 8620 EI> 92.9%). This difference in inhibition efficiency relates to the contact angle and the surface tension of the drop of Morinda Citrifolia or Aloe-Vera, in which the contact angle results greater and better adsorption to extracted of Morinda Citrifolia.

Este último é rico em antraquinonas, sendo constituído majoritariamente de aloína. No presente trabalho, foram estudados os efeitos do extrato do parênquima clorofilano (EPC) e da aloína sobre a viabilidade de células tumorais da linhagem B16F10 in vitro e a formação de vasos sangüíneos de embriões de Gallus domesticus in vivo. Na análise in vitro, células incubadas a 37ºC em atmosfera contendo 5% de CO2, foram tratadas em diferentes concentrações de aloína e de EPC. Tanto a aloína (0,01 a 230 µg?mL-1) como o EPC (0,01 a 100 µg?mL-1) reduziram a viabilidade das células tumorais. Os dados experimentais foram representados através de um modelo matemático, evidenciando que o EPC mostrou-se 2,3 vezes mais citotóxico para as células tumorais do que a aloína. Ao contrário do verificado sobre a atividade antitumoral, a aloína (10 a 320 µg?mL-1) e o EPC (10 a 320 µg?mL-1) estimularam de modo dose-dependente a vasculo/angiogênese na membrana vitelínica (MV) em 154 e 177% e a angiogênese na membrana corioalantóica (MC) em até 131 e 164%, respectivamente. Verificou-se ainda que o efeito da aloína e do EPC superaram o efeito do fator angiogênico FGFb na formação de vasos primordiais na MV (135%), sendo que para a angiogênese, na MC, apenas o EPC foi mais efetivo que o FGFb (164% versus 158%). Os tratamentos não modificaram o padrão de crescimento e a morfogênese dos embriões, com base nas medidas de comprimento total e percentual de comprimento cefálico de embriões com quatro dias de desenvolvimento. Os resultados demonstram que a aloína e o EPC exerceram efeito citotóxico especificamente nas células tumorais, mas promoveram atividade pró-vasculogênica e pró-angiogênica, superior a do fator angiogênico FGFb, sem qualquer evidência de embriotoxicidade. Com base nos resultados é possível concluir que o EPC e a substância isolada, sob estudo, mostraram concomitantemente um potencial efeito antitumoral e uma atividade estimulante em processos fisiológicos como a vascularização de tecidos normais.

This chapter reviews methods from random matrix theory to extract information about a large signal matrix C (for example, a correlation matrix arising in big data problems), from its noisy observation matrix M. The chapter shows that the replica method can be used to obtain both the spectral density and the overlaps between noise-corrupted eigenvectors and the true ones, for both additive and multiplicative noise. This allows one to construct optimal rotationally invariant estimators of C based on the observation of M alone. This chapter also discusses the case of rectangular correlation matrices and the problem of random singular value decomposition.

Full textAbstract:
Abstract Extracts of tobacco plants show considerable promise as environmentally acceptable corrosion inhibitors. Use of extracts obtained from stems and twigs, as well as leaves, show significant corrosion inhibition during immersion of aluminum or steel in saline solutions and immersion of steel in strong pickling acids. In several cases, the inhibition is greater than that provided by chromates and is provided over a wide range of extract solution concentrations. When steel was treated in sulfuric acid with tobacco extract to remove mill scale and rust, the steel emerged bright and shiny. When treated in sulfuric acid alone, the steel was blackened and pitted. The tobacco extracts provide corrosion protection from a renewable resource with little or no environmental impact. The use of waste plant material enables an inexpensive source of corrosion inhibitors.

Abstract Microbiologically influenced corrosion (MIC) is caused by problematic biofilms in many industries, especially the oil and gas industry. In this work, a novel peptide (labeled as “Peptide A”) was used to enhance tetrakis hydroxymethyl phosphonium sulfate (THPS) biocide to treat the corrosive sulfate reducing bacterium (SRB) Desulfovibrio vulgaris and a tough field biofilm consortium (labeled as “Consortium II”) on C1018 carbon steel coupons. This peptide was synthesized based on the active sequence derived from an anti-biofilm protein produced by a sea anemone. Only 10 nM Peptide A or 18 ppb (w/w) was used in the biofilm prevention test and 10 – 100 nM was tested in the biofilm removal test. The cocktail of 50 ppm THPS + 10 nM Peptide A achieved 2 extra log reduction of SRB sessile cell count in the 7-day biofilm prevention test compared with 50 ppm THPS treatment alone. In the 3-hour biofilm removal test that started with mature biofilms, the combination of 50 ppm THPS + 100 nM Peptide A achieved 2 extra log reduction compared with 50 ppm THPS treatment alone. Peptide A alone showed no log reduction in the mitigation of biofilm Consortium II. However, in the D. vulgaris biofilm removal test, 10 nM Peptide A achieved 1-log reduction and 100 nM achieved 2 logs.

Full textAbstract:
Abstract Biocorrosion, also called microbiologically influenced corrosion (MIC), is a major threat to oil and gas pipelines. The formation and morphology of biofilms can be impacted by fluid flow. Fluid velocity affects biocide distribution and MIC. Thus, testing the efficacy of a biocide for the mitigation of MIC under flow condition is desired before a field trial after a static test in vials has confirmed its efficacy. In this work, a bench-top closed flow loop system was set up to investigate the biocide mitigation of MIC of C1018 carbon steel at 25°C for 7 days using enriched artificial seawater. An oilfield biofilm consortium was analyzed using metagenomics. The biofilm consortium was grown anaerobically in the flow loop which had a holding vessel for the culture medium and a chamber in the flow path to hold coupons. Peptide A was a chemically synthesized cyclic 14-mer with its main 12-mer sequence inspired by a biofilm dispersing protein secreted by a sea anemone that has biofilm-free exteriors. The combination of 50 ppm (w/w) THPS (tetrakis hydroxymethyl phosphonium sulfate) biocide + 100 nM (180 ppb) Peptide A (biocide enhancer) resulted in extra 1-log reduction in sulfate reducing bacteria (SRB) sessile cell count and also in acid producing bacteria (APB) sessile cell count compared to 50 ppm THPS alone treatment. Furthermore, with the enhancement of 100 nM Peptide A, extra 44% reduction in weight loss and 36% abatement in pit depth were achieved compared to 50 ppm THPS alone treatment.

The main concern with protecting fruits and vegetables from bacterial infection and growth is ensuring product quality and safety. Hydroxyethyl cellulose, with –OH in the natural cellulose molecule substituted by a hydroxyethyl group, has been widely used in oil exploitation, coating, medicine, food and polymerization process. It is nontoxic and low-cost. Aloe vera is a well-known herbal plant that is used for its therapeutic properties. The gel extracted from Aloe vera plants contains a variety of biologically active compounds, phenolic contents, and minerals. In this study, the edible films containing different proportions of aloe vera and hydroxyl ethyl cellulose were prepared. The structural and antibacterial properties of the obtained edible films were examined. The obtained films were printed with inkjet. Color and adhesion properties of printed samples were determined and it was observed that the edible films showed antibacterial properties.

Full textAbstract:
Staphylococcus aureus is a gram-positive bacterium while Escherichia coli is a gram-negative bacterium that often causes infections and be used as a bacteriological model for many antibacterial screenings. Aloe vera is known to have active compounds that act as antibacterial, however, the effect of Aloe vera ethanol extract on the inhibition of growth and death of Staphylococcus aureus and Escherichia coli bacteria is not clear yet. Aloe vera was extracted using maceration in ethanol. Phytochemical tests were carried out to de-termine the active compounds in the extract [3]. To measure antibacterial efficacy, a disc diffusion method using concentrations of 3,125%, 6,25%, 12,5%, 25%, 50%, 100%, control (+) and control (-) was done using S. aureus and E. coli. Data analysis using One Way Analysis of Variance (ANOVA) test and then continued Tukey's Post Hock test with a significance of p< 0.05 [4] Minimum Inhibi-tion Concentration (MIC) and Minimum Bactericidal Concentration (MBC) was then determined with the same concentrations. The study's Aloe vera ethanol extract contained flavonoids and alkaloids. The zone of inhibitions diameter on both bacteria at the concentration of 3.125%, 6.25%, 12.5%, 25% and the negative con-trol were 0 mm. At 50% concentration, the diameter was 7.67±0.58 mm, while at 100% concentra-tion was 20.67±1.53 mm. The diameter of tetracycline and amoxicillin were 34 mm and 36 mm, respectively. MIC and MBC of Aloe vera ethanol extract against Staphylococcus aureus at a concen-tration of 12.5% while against Escherichia coli at a concentration of 25%. Aloe vera ethanol extract has antibacterial effects and is able to inhibit and kill Staphylococcus aureus and Escherichia coli bacteria with higher inhibitory power against Staphylococcus aureus than against Escherichia coli.

Micro-terrain and canopy feature extraction by breakline and differencing analysis of gridded elevation models : identifying terrain model discontinuities with application to off-road mobility modeling. Engineer Research and Development Center (U.S.), 2021. http://dx.doi.org/10.21079/11681/40185.
Full textAbstract:
Elevation models derived from high-resolution airborne lidar scanners provide an added dimension for identification and extraction of micro-terrain features characterized by topographic discontinuities or breaklines. Gridded digital surface models created from first-return lidar pulses are often combined with lidar-derived bare-earth models to extract vegetation features by model differencing. However, vegetative canopy can also be extracted from the digital surface model alone through breakline analysis by taking advantage of the fine-scale changes in slope that are detectable in high-resolution elevation models of canopy. The identification and mapping of canopy cover and micro-terrain features in areas of sparse vegetation is demonstrated with an elevation model for a region of western Montana, using algorithms for breaklines, elevation differencing, slope, terrain ruggedness, and breakline gradient direction. These algorithms were created at the U.S. Army Engineer Research Center – Geospatial Research Laboratory (ERDC-GRL) and can be accessed through an in-house tool constructed in the ENVI/IDL environment. After breakline processing, products from these algorithms are brought into a Geographic Information System as analytical layers and applied to a mobility routing model, demonstrating the effect of breaklines as obstacles in the calculation of optimal, off-road routes. Elevation model breakline analysis can serve as significant added value to micro-terrain feature and canopy mapping, obstacle identification, and route planning.

Full textAbstract:
Forming the foundations of large-scale knowledge bases, probabilistic databases have been widely studied in the literature. In particular, probabilistic query evaluation has been investigated intensively as a central inference mechanism. However, despite its power, query evaluation alone cannot extract all the relevant information encompassed in large-scale knowledge bases. To exploit this potential, we study two inference tasks; namely finding the most probable database and the most probable hypothesis for a given query. As natural counterparts of most probable explanations (MPE) and maximum a posteriori hypotheses (MAP) in probabilistic graphical models, they can be used in a variety of applications that involve prediction or diagnosis tasks. We investigate these problems relative to a variety of query languages, ranging from conjunctive queries to ontology-mediated queries, and provide a detailed complexity analysis.

Full textAbstract:
This research was aimed to develop an active film from chitosan film incorporated with green tea extract to enhance antioxidant and antimicrobial properties in order to be used for food shelf life extension. The experiments were divided into 3 parts. Firstly, chitosan-based film preparation and modification were determined. The results suggested that the optimum chitosan films could be prepared from 2% chitosan in 1% acetic acid. However, the chitosan film was brittle and had low flexibility. Mechanical property of chitosan film was modified by adding different concentrations of glycerol, as a plasticizer, including 0, 10, 20, 30, 40 and 50% (w/w of chitosan). The effect of plasticizer concentration on the mechanical properties of the chitosan film was determined by measuring their tensile strength, elongation at break, thickness, surface colors and water vapor transmission rate. The results showed that 30% glycerol was the optimum concentration to improve flexibility, while maintaining tensile strength and other physical properties of the film. Secondly, chitosan-based film was incorporated with green tea extract (GT) in order to improve film’s antioxidant and antimicrobial properties. The optimum concentration of green tea extract was then determined by adding 0, 2, 5, 10 and 20% (w/v) of green tea in film-forming solution, and tensile strength, elongation at break, water vapor permeability (WVP), density, total phenolic compounds (TPC), radicals scavenging 2,2-diphenyl-1-picrylhydrazyl (DPPH) of the film were determined. Fourier Transform Infrared (FTIR) spectrometry was carried out to observe the potential modifications of the chitosan films when incorporated with GTE. The ability to inhibit Staphylococcus aureus TISTR 118, Salmonella enteritidis DMST 17368, Escherichia coli TISTR 780 and Pseudomonas fluorescens TISTR 358 was conducted using agar diffusion method. It was found that WVP and lightness (L) decreased, while density, TPC, DPPH scavenging activity, redness (a), and yellowness (b) increased with increasing green tea concentration. The results also showed that films containing green tea extract had inhibition zone and could inhibit bacterial growth underneath film, while chitosan-alone film had no inhibition zone. The results suggested that incorporation of GT into chitosan films improved mechanical and water vapor barrier properties and enhanced polyphenolic content, antioxidant activity and antimicrobial property of the films. Changes in the FTIR spectra of the chitosan films were observed when GTE was incorporated, suggesting some interactions occurred between amine group of chitosan and hydroxyl group of green tea polyphenols. Lastly, the chitosan film containing green tea extract (CGT-film) was used as an active film for shelf life extension of pork sausage. Qualities of pork sausages wrapped with CGT-film were compared with those wrapped with chitosan-alone film without green tea incorporation (C-film) and those without chitosan film wrapping (Control). Changes in the physical qualities including color values and texture, the chemical qualities including pH and thiobarbituric value (TBA), the microbiological qualities including total plate count, yeasts/moulds, and lactic acid bacteria were determined throughout the storage. The sensory qualities including odor, color, slime formation, and overall acceptance were also evaluated using Quantitative Descriptive Analysis. The results showed that samples wrapped with CGT-film had higher cutting force, lightness and yellowness values, but lower TBA and microbial growth than those wrapped with C-film and control. Based on microbiological analysis and sensory evaluation, control samples and those wrapped with C-film had shelf life of less than 12 and 20 days, respectively. Samples wrapped with GCT-film had better qualities than other samples and had shelf life of up to 20 days at 4℃. Incorporation of GT into chitosan film could enhance the antioxidant and antiomicrobial properties of the film. CGT-film reduced the lipid oxidation and inhibited microbial growth and, consequently, could maintain qualities and extended shelf life of the pork sausage.

Full textAbstract:
Chemical composition and biological role of the surface coat (SC) of the root-knot nematodes, Meloidogyne spp. are described. SC proteins of M. incognita race 3 infective juveniles (J2) were characterized by electrophoresis and western blotting of extracts from radioiodine and biotin-labelled nematodes. J2 labelled with radioiodine and biotin released 125I and biotin-labelled molecules into water after 20 hours incubation, indicating that SC proteins may be loosely attached to the nematode. Antiserum to the principal protein reacted with the surface of live J2 and with surface proteins previously separated by electrophoresis. Human red blood cells (HRBC) adhered to J2 of several tylenchid nematodes over the entire nematode body. HRBC adhered also to nylon fibers coated with SC extracted from M. javanica J2; binding was Ca++/Mg++ dependent, and decreased when the nylon fibers were coated with bovine serum albumin, or pre-incubated with fucose and mannose. These experiments support a working hypothesis that RBC adhesion involves carbohydrate moieties of HRBC and carbohydrate-recognition domain(s) (CRD) distributed on the nematode surface. To our knowledge, this is the first report of a surface CRD i the phylum Nematoda. Gold-conjugated lectins and neoglycoproteins combined with silver enhancement have been used for the detection of carbohydrates and CRD, respectively, on the SC of M. javanica J2. Biotin reagents were used to trace surface proteins, specifically, on live J2. The labile and transitory nature of the SC was demonstrated by the dynamics of HRBC adherence to detergent-treated J2, J2 at different ages or fresh-hatched J2 held at various temperatures. SC recovery was demonstrated also by a SDS-PAGE profile. Monoclonal antibodies developed to a cuticular protein of M. incognita J2 gave a slight, but significant reduction in attachment of Pasteuria penetrans spores. Spore attachment as affected by several enzymes was inconsistent: alcian blue, which specifically blocks sulfyl groups, had no afffect on spore attachment. Treatment with cationized ferritin alone or catonized ferritin following monoclonal antibody caused significant decreases in spore attachment. Those results suggest a role in attachment by negatively charged groups.

Full textAbstract:
Background. Obsessive compulsive disorder (OCD) is a common, chronic, and impairing psychiatric disorder that often begins in childhood or adolescence. Early identification and treatment of OCD is important to prevent a cascade of developmental disruptions lasting into adulthood. The 2012 American Academy of Child and Adolescent Psychiatry (AACAP) Practice Parameter recommends cognitive behavioral therapy that incorporates exposure and response prevention (ERP) as a first-line treatment for mild-to-moderate OCD in youth and recommends combined treatment with ERP (if feasible) and a selective serotonin reuptake inhibitor (SSRI) for some patients, particularly those with more severe symptoms. Clinical uncertainty exists regarding the optimal treatment strategies (and treatment combinations) that work best for specific populations and settings. In this report, we seek to evaluate the accuracy of brief assessment tools to identify OCD in symptomatic youth (Key Question [KQ] 1) and the effects and harms of treatment options for youth with OCD (KQ2). Methods. We searched Medline®, Cochrane, Embase®, CINAHL®, and ClinicalTrials.gov from inception to May 15, 2024. After double screening, we extracted study data, assessed risk of bias, and conducted network and pairwise meta-analyses. We evaluated the strength of evidence (SoE) using standard methods. The protocol was registered in PROSPERO (registration number CRD42023461212). Results. We found 117 studies (reported in 161 papers) that met inclusion criteria. Of these, 31 cross-sectional studies pertained to KQ1, diagnosis of OCD. For KQ 2, treatment of OCD, we included 71 randomized controlled trials, 2 nonrandomized comparative studies, and 13 single-arm studies that reported potential treatment effect modifiers. For KQ1, there is insufficient evidence regarding most brief assessment tools. Based on nine studies, the Child Behavior Checklist-Obsessive Compulsive subscale (CBCL-OCS) may have sufficiently high sensitivity and specificity to identify patients for specialist referral and diagnostic evaluation (moderate SoE). For KQ2, meta-analyses indicate that in-person ERP is more effective for OCD symptoms when compared to either waitlist (high SoE) or behavioral control (moderate SoE), and for remission when compared to waitlist (high SOE) or behavioral control (moderate SoE). ERP via telehealth is more effective than waitlist for OCD symptoms (high SoE) and remission (moderate SoE). SSRIs are more effective than placebo for OCD symptoms and global severity (high SoE). Clomipramine is probably more effective than placebo (moderate SoE). When used together, ERP and an SSRI are probably more effective than treatment with an SSRI alone for OCD symptoms (moderate SoE). ERP combined with an SSRI are as effective as ERP alone for OCD symptoms (high SoE). The side effects of SSRIs and clomipramine were inconsistently reported, precluding graded conclusions. Augmentation of ERP with D-cycloserine is as effective as ERP alone to reduce OCD symptoms (high SoE) or global severity (moderate SoE). The evidence was insufficient regarding potential effect modifiers. Conclusion. The diagnosis of OCD relies on expert clinical evaluation, sometimes augmented by semi-structured interviews. The CBCL-OCS may be sufficiently accurate to indicate which youth should be further evaluated for OCD. ERP, delivered in-person or via telehealth, is an effective treatment for OCD in children and adolescents. ERP, alone or in combination with an SSRI, is probably more effective than treatment with an SSRI alone.

Full textAbstract:
Forests are important socio-economic assets in many low-income countries. However, they are often over-exploited as governments do not sufficiently valorise them, including by taxing them inefficiently. This is the case across Nigeria, where forest management and taxation has been effectively decentralised from the federal government to individual states. In this paper we assess the current forestry tax regime in Ekiti State, one of the eight Nigerian states where forests represent more than 50 per cent of land area, and where forest revenue has been historically relevant. Based on 16 interviews with government state officials, forest officers and actors from the industry, as well as data from the Forestry Commission, our analysis suggests that the ongoing depletion of forest resources in the state seems to be partially connected to an excessive focus on their capacity to generate revenue. The conceptualisation of the Ekiti State Forestry Commission as a revenue-raising agency rather than a management one, a continuous drive to extract revenue from the sector through outdated tax rates, and a view of the industry potential disconnected from the existing stock, all perversely led to a lower contribution from forestry to the state budget. While there is potential to reform both the structure of forestry taxes and their method of administration, evidence from our interviews suggests that priority should be given to enforcing a ban on forest exploitation for a period that is long enough to allow for its regrowth, at least in government reserves. This will require substantial sensitisation and engagement with actors in the sector, as well as increasing the monitoring capacity of the Forestry Commission. The Forestry Commission does not currently have enough staff to guarantee the enforcement of existing legislation, let alone a ban on all forest activities.

Full textAbstract:
A growing number of countries are committed toreduce their carbon emissions and are transitioning towards renewable and clean energy sources, leading to an in crease in demand formetals and minerals. This is especially the case for a short list of what are called "critical minerals" which are considered essential to economic development, including the transition to a low-carbon economy and national security. There liability of their supply chain raises concerns considering geological scarcity, difficulty to extract and/or political factors influencing their availability. At the same time, public awareness and perception of geoscience are eroding and there is more and more reluctance towards mining projects, even from traditionally favourable communities. To face this challenge, promote public interest and outline the contribution of geological science to society, geoscientists of the Geological Survey of Canada (GSC-Québec) have designed and put together a portable display that includes a suite of mineral and metal samples considered critical for the sustainable success of Canada's transition towards a clean and digital economy. The display is a user-friendly toolkit that can be used by any GSC geoscientists during outreach activities, in classrooms as well as during public open houses. It comes with straightforward pedagogic material and content, along with presentation scenarios. To broaden and adapt the workshops to specific expectations, additional toolkits were developed and all are contained within easy to carry travel cases. These cover a variety of topics and can be presented as stand-alone displays or be used complementary to one another. For example, the "Mines and minerals" collection may serve as a supplement to the "Critical minerals" display to present every day objects in which minerals are used as well as ores amples from active mines to illustrate the intertwining between mining activities and our everyday lives. Another display covers the ever-popular fossils thematic with the "Sedimentary rocks and fossils" collection and gives an opportunity to address key geoscience themes such as life evolution and biological crisis along with groundwater reservoirs and resources. The "Magmatic rocks" display touches on the formation of rocks from magmas, the different types and active processes of volcanoes, and discusses the risks and benefits related to volcanic activity. Hopefully, these four ready-to-use portable displays will encourage more GSC geoscientists to engage in public oriented activities to make geosciences more accessible, change perceptions and offer an overall tangible scientific experience for people.

Full textAbstract:
Objective Provide a timely, rigorous and continuously updated summary of the evidence on the role of remdesivir in the treatment of patients with COVID-19. Methods Eligible studies were randomized trials evaluating the effect of remdesivir versus placebo or no treatment. We conducted searches in the special L·OVE (Living OVerview of Evidence) platform for COVID-19, a system that performs regular searches in databases, trial registries, preprint servers and websites relevant to COVID-19. All the searches covered the period until 25 August 2020. No date or language restrictions were applied. Two reviewers independently evaluated potentially eligible studies according to predefined selection criteria, and extracted data on study characteristics, methods, outcomes, and risk of bias, using a predesigned, standardized form. We performed meta-analyses using random-effect models and assessed overall certainty in evidence using the GRADE approach. A living, web-based version of this review will be openly available during the COVID-19 pandemic. Results Our search strategy yielded 574 references. Finally, we included three randomized trials evaluating remdesivir in addition to standard care versus standard care alone. The evidence is very uncertain about the effect of remdesivir on mortality (RR 0.7, 95% CI 0.46 to 1.05; very low certainty evidence) and the need for invasive mechanical ventilation (RR 0.69, 95% CI 0.39 to 1.24; very low certainty evidence). On the other hand, remdesivir likely results in a large increase in the incidence of adverse effects in patients with COVID-19 (RR 1.29, 95% CI 0.58 to 2.84; moderate certainty evidence). Conclusions The evidence is insufficient for the outcomes critical for making decisions on the role of remdesivir in the treatment of patients with COVID-19, so it is impossible to balance potential benefits, if there are any, with the adverse effects and costs.

Full textAbstract:
Objective The aim of this living systematic review is to provide a summary of the effects of remdesivir in the treatment of patients with acute covid-19. Methods Eligible studies were randomized trials evaluating the effect of remdesivir versus placebo or no treatment. We conducted searches in the special L·OVE (Living OVerview of Evidence) platform for COVID-19, a system that performs regular searches in databases, trial registries, preprint servers and websites relevant to COVID-19. All the searches covered the period until 25 August 2020. No date or language restrictions were applied. Two reviewers independently evaluated potentially eligible studies according to predefined selection criteria, and extracted data on study characteristics, methods, outcomes, and risk of bias, using a predesigned, standardized form. We performed meta-analyses using random-effect models and assessed overall certainty in evidence using the GRADE approach. A living, web-based version of this review will be openly available during the COVID-19 pandemic. Results Our search strategy yielded 574 references. Finally, we included three randomized trials evaluating remdesivir in addition to standard care versus standard care alone. The evidence is very uncertain about the effect of remdesivir on mortality (RR 0.7, 95% CI 0.46 to 1.05; very low certainty evidence) and the need for invasive mechanical ventilation (RR 0.69, 95% CI 0.39 to 1.24; very low certainty evidence). On the other hand, remdesivir likely results in a large increase in the incidence of adverse effects in patients with COVID-19 (RR 1.29, 95% CI 0.58 to 2.84; moderate certainty evidence). Conclusions The evidence is insufficient for the outcomes critical for making decisions on the role of remdesivir in the treatment of patients with COVID-19.
