Plant growth promoting rhizobacteria are colonized bacterial species that has the capability to improve plant growth by certain direct and indirect means. Environmental factors including both biotic and abiotic stresses are among the major constraints to crop production. In the current study, the effectiveness of microbial inoculation (Bacillus megaterium) for enhancing growth of tomato plants under salt stress conditions has been investigated. Significant improvement in shoot length, root length, leaf surface area, number of leaves, total weight of the shoot and root was observed in tomato plants inoculated with zm7 strain post 15 and 30 days of its application. Zm3, Zm4 and Zm6 strains improved the morphological parameters as compared to the control. Chlorophyll content a, chlorophyll content b, anthocyanin and carotenoid content was increased in tomato plants subjected to Zm7, Zm6 and Zm4 strains. Stress responsive genes; metallothionein and glutothion gene were found highly expressed in Zm7 treated tomato plants as compared to control, untreated plants. Significant correlation of anthocyanin was reported for carotenoids, chlorophyll-b, shoot weight and total weight of seedling while carotenoids were significantly correlated with leaf surface area, root length, chlorophyll-b and anthocyanin. Overall, Zm7 strain proved best for improvement in salt stressed plant’s morphological parameters and biochemical parameters as compared to control, untreated plants.

Full textAbstract:
Tar accumulation can result in blockage, corrosion, and poisoning of catalyst. One of the methods applicable for tar removal is by using a catalyst that enhances steam reforming reaction. In this study, natural zeolites were modified for the use as tar steam reforming catalyst. This study also covers characterizing the modified natural zeolite by ion exchange and acid leaching, and measuring its activity as toluene steam reforming catalyst. The XRD pattern showed that natural zeolite contains three crystalline phases, i.e. mordenite, clinoptilolite, and heulandite. The main structure of the mordenite phase was also detected by using FTIR analysis on T-O stretching band with the range of 1045-1075 cm-1. The zeolite modification by ion exchange and acid leaching resulted in decreasing content of impurities, such as Na and K, and the decrease in crystallinity from 68.8% to 61.8%. The surface area increased from 16 m2/g to 31.4 m2/g and 161.8 m2/g for ZMH (after ion exchange), ZM3 (after acid leaching for 3 hour), and ZM6 (after acid leaching for 6 hour) respectively. Theses catalyst gave toluene conversion of 30.5% to 42.6% and 54% respectively.

Full textAbstract:
Background: In countries like Ethiopia where the spread of HIV infection is extensive, health services are faced with an increased demand for care. The most obvious reflection of this increased demand is through patient load, longer bed occupancy perhaps to the exclusion of patients with other ailments. Objective: The purpose of this study was to describe the bed occupancy rate and the average length of stay of HIV/AIDS inpatients of three major public hospitals. Methods: A Retrospective Cross-sectional study was conducted in three major hospitals of Addis Ababa namely Zewditu Memorial Hospital, Tikure Anbessa Hospital and Saint Paul's Hospital from February to March 2004. Results: Of the total 453 sampled inpatients, 293 (65 %) were HIV positives. Over half (55.0%) were Males. The most affected age group was between 24 and 56 years. The majority (85.8%) were from Addis Ababa and over half (57.7%) was married. Housewives constituted about a quarter (26.3%) of all the admitted cases. The most common co-morbidities resulted in admission to the medical wards among the HIV-positive cases were Tuberculosis (73.0%) and jirovicii pneumonia (70.3%), and their occurrence was significantly higher among HIV+ than their counter parts (p = 0.001). Although numbers of patients admitted in Tikur Anbesa hospital was more than Saint Paul's and Zewditu Memorial hospitals (ZMH), the proportion of HIV positive cases admitted to ZMH however was higher (49.0%) than Tikur Anbessa (14.0%) and Saint Paul's hospitals (18.0%). Likewise the number of inpatient days was also higher in ZMH (n=7765) than the other hospitals. The bed occupancy rate was however, higher in ZMH (53.0%) than Tikur Anbessa (12.0%) and Saint Paul's (12.0%) hospitals. Conclusion: One of the most obvious consequences of HIV/AIDS patients are the increased occupancy of hospitals beds suggesting that only 81.1 % of the beds are for all other afflictions in the hospitals. It appears that there is a lot of concern that patients with HIV are competing with the non-HIV infected patients in a resource limited areas. Home based care with community involvement and greater use made of existing community resources might be a response to the limitations of curative hospital-based care and treatment needs of many HIV/AIDS patients.

Scorpions have always inspired fear and fascination because of the potency of their venoms. Although this ancient arachnid group is relatively small (ca. 2400 species) and has been continuously studied for the past century, the taxonomy is still in a state of flux and the correct identification of species often remains difficult. With more than 725 species and 9000 specimens, the Zoological Museum in Hamburg (ZMH) holds one of the largest and most significant scorpion collections in the world. This collection also contains many historical types described by Karl Kraepelin in the early 20th century. In order to contribute to a more stable scorpion taxonomy and to assist future scorpion researchers, we present an illustrated and annotated catalogue of the ZMH scorpion collections. The type specimens of 89 species belonging to 10 families are documented, imaged and assessed alongside their primary data. For practical reasons, only the taxa belonging to the parvorder Iurida Soleglad et Fet, 2003 are presented here whilst the Parvorder Buthida Soleglad et Fet, 2003 will be catalogued in a second publication.

Full textAbstract:
Centipedes (Myriapoda: Chilopoda) are carnivorous arthropods that live in leaf litter and soil habitats on all continents except Antarctica. Roughly 3,300 species have been described to date but the taxonomy is still progressing and requires a thorough documentation of type material and type deposits. In this paper we provide an annotated catalogue of the centipede type collection at the Zoological Museum (ZMH) in Hamburg. This collection comprises 490 type specimens belonging to 141 taxa originally described as species, subspecies and varieties. More than half of these taxa were described by the pioneering myriapodologists Carl Graf Attems (Vienna) and Karl Kraepelin (Hamburg). The collection includes material representing 93 valid species or subspecies and contains specimens predominantly from Australia (33%), Asia (22%), Africa (20%) and South America (20%). Taxonomically, the focus is on the centipede orders Scolopendromorpha (56 valid species) and Geophilomorpha (28 valid species) with fewer types for the Lithobiomorpha (8 species). A total of 48 taxa (34% of type species) have been synonymized since they were originally described and the type material for 12 additional species at the ZMH is lost. We provide a brief historical overview of this collection from its origin at the Museum Godeffroy and the Johanneum in Hamburg, including the most relevant taxonomists and collectors, followed by an annotated taxonomic catalogue with details on all species that are or were represented by type material.

Full textAbstract:
Species of the genus Zenarchopterus are marine, brackish, and freshwater fishes that have modified dorsal-fin and anal-fin rays in adult males. There are 19 valid species worldwide. Three species have been recorded from Taiwan, namely Zenarchopterus buffonis (Valenciennes, in Cuvier & Valenciennes, 1847), Z. dispar (Valenciennes, in Cuvier & Valenciennes, 1847), and Z. dunckeri Mohr, 1926. However, Collette and Su (1986) noted one uncertain species (female, labeled “Zenarchopterus sp., Takao, Formosa, Hans Sauter, V–VII 1907”) in the Museum of Nature Hamburg (ZMH) from southern Taiwan. This species has only nine pectoral-fin and anal-fin rays, a longer snout, and does not agree well with any other species. In this study, Zenarchopterus takaoensis sp. nov. is described based on seven newly collected specimens from southwestern Taiwan and one (ZMH 6543, 59.4 mm SL) from southern Taiwan. This new species differs from its congeners by the following combination of characters: snout slightly longer, prominent pigmentation or dark mark on snout; nine anal-fin rays, 6th anal-fin ray not elongated or thickened in adult male; dorsal body pigmented with three longitudinal dashed lines, oval-like dashed pigmentation on dorsal lateral series scales; anterior lateral stripe on body in dashed line, ventral body with one longitudinal dashed line. In this study, specimens were examined and compared; morphological evidence revealed it is a hidden species. Taxonomic accounts, distribution, and a key to the congener species of Taiwan, along with color photographs of the new species, are provided.

After bivariable analysis, clinically relevant variables and variables with a p-value &lt; 0.2 were included in multivariable logistic regression analysis. Statistical significance was set at p-value &lt; 0.05. &lt;i&gt;Results:&lt;/i&gt; The overall successful treatment outcome (cured or completed) was 197 (83.1%). Factors significantly associated with poor treatment outcomes included age group 35 to 44 years (AOR=4.663; 95% CI: 1.215-17.901), extrapulmonary TB (AOR=3.451; 95% CI: 1.172-10.16), and registration in 2019 (AOR=4.367; 95% CI: 1.2-15.87). &lt;i&gt;Conclusion:&lt;/i&gt; The treatment success rate falls short of the national target of 85%, highlighting the need for targeted improvements in TB management. The associations with age and extrapulmonary TB emphasize the necessity for focused control measures. Strengthening targeted TB programs at ZMH is recommended.

Background. Anemia is one of the most commonly observed hematological abnormalities and an independent prognostic marker of HIV disease. The aim of this study was to determine the magnitude of anemia and associated factors among pediatric HIV/AIDS patients attending Zewditu Memorial Hospital (ZMH) ART Clinic in Addis Ababa, Ethiopia.Methods. A cross-sectional study was conducted among pediatric HIV/AIDS patients of Zewditu Memorial Hospital (ZMH) between August 05, 2013, and November 25, 2013. A total of 180 children were selected consecutively. Stool specimen was collected and processed. A structured questionnaire was used to collect data on sociodemographic characteristics and associated risk factors. Data were entered into EpiData 3.1.1. and were analyzed using SPSS version 16 software. Logistic regressions were applied to assess any association between explanatory factors and outcome variables.Results. The total prevalence of anemia was 22.2% where 21 (52.5%), 17 (42.5%), and 2 (5.0%) patients had mild, moderate, and severe anemia. There was a significant increase in severity and prevalence of anemia in those with CD4+ T cell counts below 350 cells/μL (P<0.05). Having intestinal parasitic infections (AOR = 2.7, 95% CI, 1.1–7.2), having lower CD4+ T cell count (AOR = 3.8, 95% CI, 1.6–9.4), and being HAART naïve (AOR = 2.3, 95% CI, 1.6–9.4) were identified as significant predictors of anemia.Conclusion. Anemia was more prevalent and severe in patients with low CD4+ T cell counts, patients infected with intestinal parasites/helminthes, and HAART naïve patients. Therefore, public health measures and regular follow-up are necessary to prevent anemia.

Full textAbstract:
The hitherto monospecific genus Pleonoporus is revised based on the syntypes of P. robustus Attems, 1938, housed in Naturhistorisches Museum Wien (NHMW), as well as on specimens of what we interpret as a new species of the genus, Pleonoporus tanzanicus sp. nov., collected in Tanzania and housed in the Museum of Nature – Zoology, Leibnitz Institute for the Analysis of Biodiversity Change (ZMH) for more than a century. Both species are described based on habitus and gonopod structures and illustrated with micrographs, whereas scanning electron microscope images are also provided for the new species. This paper further highlights the importance of natural history collections for taxonomic research and studies on species diversity in general.

Full textAbstract:
Background Diabetes mellitus is a common health problem worldwide. Proper insulin administration plays an important role in long term optimal blood sugar control. Adequate knowledge and attitude about insulin self-administration could also improve the management of diabetes and eventually improve the quality of life. This study aimed to assess knowledge, attitude and practice towards insulin self-administration and associated factors among diabetic patients at Zewditu Memorial Hospital (ZMH), Ethiopia. Methods An institution-based cross-sectional study was conducted among 245 diabetic patients who were selected by systematic random sampling during follow-up at ZMH. The data was collected using an interviewer-administered structured questionnaire and analyzed by SPSS v.20. Binary logistic regression was used to identify associated factors of patients’ knowledge and P < 0.05 was used to declare the association. Results Among 245 patients enrolled, 53.9% were male with a mean age of 53.26 ±13.43 years and more than 84% of the patients can read and write. The overall patients’ knowledge was 63.4%. Better knowledge was observed concerning timing (78.4%) and site of insulin injection (89.4%), while knowledge on the angle of inclination during insulin administration (43.3%) and complications of insulin therapy (49%) were low. Patients who were male gender, never married, government or NGO employees, urban residents, who completed elementary and higher education had a higher knowledge than their comparators. The majority (62%) of the study patients had a favorable attitude on insulin self-administration. Although the majority 177(72.2%) of the study patients have administered insulin themselves, only 120(49.0%) of the patients injected insulin appropriately at 450. Frequent repetition of the injection site was practiced among 176(71.8%) patients and 139(56.7%) injected insulin before or immediately after food intake. Conclusion Patients’ knowledge and attitude seem suboptimal and malpractice of insulin self-administration was reported. Therefore, the gaps should be addressed through patient education and demonstration of insulin injection during each hospital visit.

Agricultural waste leads to a number of environmental issues, including pollution and environmental degradation. In Nigeria, Zea mays husk is one of the most prevalent agricultural wastes, and it can be turned into a valuable resource of quality cellulose. The goal of this study was to establish a low-cost and sustainable chemical treatment method for isolating cellulose from Z. mays husk feedstock. A series of alkaline delignification, digesting, and bleaching techniques were used to extract and purify cellulose. TAPPI T203 OS-74, TAPPI T222 OS-83 and TAPPI T222 OM-02 methods were used to determine the cellulose, hemicellulose and lignin contents, respectively. The samples were also characterised by scanning electron microscopy, X-ray diffraction, Fourier transform infrared spectroscopy (FTIR), and CHNS/O analyses. The resulting product was found to contain 97.95% α-cellulose, 0.19% β-cellulose, and 1.86% γ-cellulose. The presence of 40.95% carbon, 2.98% hydrogen, 0.72% nitrogen, 0.07% sulphur, and 55.28% oxygen was found by the CHNS/O analysis of cellulose. The untreated husk microscopy displayed an uneven, flake-like, and non-uniform surface, whereas the delignified husk, digested husk, and pure cellulose (ZMH-C) micrographs revealed, respectively, a smooth non-uniform surface, an irregular porous surface, and a smooth wool-like surface. The FTIR spectra of the treated samples demonstrated an increase in the intensity of the polar property of the OH group, as well as the elimination of the hemiacetal group and β-1,4-glycosidic linkages. The ZMH-C diffractogram verified the existence of characteristic 2θ peaks of cellulose at 220, 240, and 300, as well as a 4.7% crystallinity index. The comparatively low-temperature sequential alkaline delignification, digesting, and bleaching method adopted extracted low-lignin crystalline cellulose material from Z. mays husk. The flexibility, biodegradability, and availability of husk make it a viable source of high-quality cellulose with several possible applications. Z. mays cellulose has been thus demonstrated to be an appealing material for a wide variety of industries seeking environmentally acceptable and sustainable solutions.

Introduction: Human Immunodeficiency Virus causes an immense amount of problems throughout the world, especially in sub-Saharan countries. Recently viral load is thought to be a good indicator in assessing HIV progression. Complementary feeding practice and type of complementary food are the major factors that affect VL Status. However, in Ethiopia there is paucity of evidence on the factors that could affect viral load among HIV exposed infants. Therefore, this study aimed to identify factors that affect VL Status among HIV positive children on ART at Zewditu Memorial Hospital (ZMH), Addis Ababa, Ethiopia using a case control study design. Methods: Institution based unmatched case- control study was employed among a total of 241 (71 cases and 170 controls) children attending for follow up in ZMH ART clinic from July to August 2020. The interviewer conducts a face-to-face interview for 24 hour’s dietary diversity from mothers using standardized and pre tested questioner. SPSS 20 was used for data entry and cleaning, while Stata 14 was used for data analysis. Backward stepwise logistic regression analysis was used to determine the association of the factors with the outcome variable. A P-value ≤ 0. 05 was considered statistically significant at 95% confidence level throughout the study. Result: Out of 241 children, 71 of them had high VL status, while the rest 170 of them had low VL status. Poor dietary diversity increases the risk of high VL on ART children [AOR= 4. 37, 95% CI: 2. 12-10. 71]. The risk of high VL increase on children whose mother’s marital status was single [AOR=4, 95% CI: 1. 40, 9. 70], among children who have a daily laborer mothers [AOR= 10. 6, 95% CI: 3. 20, 21. 67], and working on nongovernmental organizations [AOR=5. 32, 95% CI: 1. 68, 10. 51]. Children on WHO clinical stage 3 and 4 [AOR =15. 22, 95% CI: 4. 1, 39. 41], those children who started complementary feeding lately (after 6 months) [AOR= 4. 69, 95% CI: 2. 35, 13. 6] and children with poor Infant dietary diversity score [ AOR= 4. 37, 95% CI: 2. 12-10. 71]. Conclusion: Maternal marital status, maternal occupation, WHO clinical stage, late initiation of complementary feeding practice, and infant dietary diversity score are the factors affecting VL status in HIV positive children on ART at Zewditu memorial hospital.

A number of chondrichthyan fish species were caught on long-line in the Rockall Trough (north-east Atlantic) in 1997, which are first records for this area; Raja hyperborea, Raja kukujevi and Raja fullonica. The occurrence of R. hyperborea, usually found in colder boreal waters appears to be temperature related. The presence of the deep water squaliform shark Centrophorus uyato in the area was also confirmed and several species were caught at previously undocumented depths.The Rockall Trough is an extension of the North Atlantic deep environment (Mauchline, 1990). A long-line survey was undertaken in August 1997 on the eastern and southern slopes of the Rockall Trough (Figure 1), fishing gear and procedures are described by Connolly (1997). Identifications were undertaken by means of several texts (Compagno, 1984; Whitehead, et al., 1984; Stehmann, 1997). The specimens described below were lodged in the National Museum of Ireland (NMI) and the Hamburg University Zoological Museum, Germany (ZMH). Depth ranges, positions and catalogue numbers of the specimens described are given in Table 1.

Abstract The use of magnesium alloys in aerospace is relatively restricted by their poor ignition resistance performance. A continuous heating test was conducted to investigate the ignition resistance of pure Mg, ZM5, and ZM6 magnesium alloys with different alloying elements. It was found that alloying elements greatly influenced the ignition resistance of magnesium alloys. With about 2% addition of Nd rare earth element, ZM6 had a higher ignition temperature than pure Mg. In comparison, the ignition temperature of ZM5, which contains mainly about 8% Al alloying element, was lower than that of pure Mg. Analysis of high-temperature surface oxide film reveals that the higher ignition temperature of ZM6 resulted from a protective Nd2O3 oxide film formed on the oxidized surface. Alloying with rare earths can improve the ignition resistance of magnesium alloys.

Abstract Christoph D. Schubart is remembered as an outstanding carcinologist who left behind an enormous scientific legacy and a huge collaborative network with scientists from all over the world. Throughout his career, Christoph was also able to compile an extremely valuable crustacean collection, including physical specimens, DNA extracts, and tissues of many thousands of specimens. After his sudden death in early 2023, these valuable collections have been transferred from the University of Regensburg to the Leibniz Institute of Biodiversity Change (LIB). Molecular samples are now housed at the LIB Biobank in Bonn (ZFMK), and the physical specimens are deposited at the LIB Crustacea Collection in Hamburg (ZMH). The collections include marine (70%), freshwater (25%) and terrestrial (5%) material from all over the world. A preliminary list of the taxa potentially included in the collections is provided herein, which includes approximately 375 genera, 104 families, nine orders, and two crustacean classes. This note aims to provide the first insights into the Schubart collections and to encourage the scientific community to use this resource extensively, preserving the scientific legacy of Christoph Schubart, thus inspiring new emerging questions on decapod research.

Types represent the ultimate taxonomic information of a species and hence represent the most important specimens in museums. The entomological collections of the Zoological Museum Hamburg (now part of the Centrum für Naturkunde) hold several thousand primary types of insects. However, despite their importance currently no type database exists and catalogues have not been updated since almost 50 years and are only available in German. Following the publication of our catalogue of Caelifera types, we here present an updated catalogue for the Ensifera types held in the collection in English language. 74 species are represented as types with 105 specimens; of these 44 are name-bearing types: 36 holotypes, 3 lectotypes, 4 syntypes and 1 neotype. The remaining specimens are para- (55), paralecto- (4), allo- (1) and neoallotypes (1). Most of the species were described by Max Beier (18), Tevfik Karabak (13), Josef Redtenbacher (13) and the former curator of the collection Herbert Weidner (10). In his catalogues in 1966 and 1977 Weidner recorded types of 73 species present in the collection and an additional 65 as potentially lost in the war; 71 of the types recorded by Weidner were still present, whereas two could not be found (Xiphidiumgeniculare Redtenbacher, 1891; Xiphidiumlongipes Redtenbacher, 1891); one species recorded as lost by Weidner was found (Lezinaacuminata Ander, 1938) and one species (neoallotype of Paradecolyainexspectata Chopard, 1957) and one additional type individual (paratype of Choeroparnopsforcipatus Beier, 1949) are newly reported for the collection.

Full textAbstract:
Background. There is limited information and research carried out regarding the prevalence of poststroke depression (PSD) in the study area. Psychiatric disorders complicate a significant proportion of patients suffering from stroke. This of course have a great negative impact on our knowledge about poststroke depression in Ethiopia, and poststroke depression complicates a significant number of stroke patients and their rehabilitation. Methods. A cross-sectional study on all patients aged above 18 years and diagnosed with stroke in the past two years who attended the neurology follow-up clinics of Tikur Anbessa Specialized Hospital (TASH) and Zewditu Memorial Hospital (ZMH) was done by using a structured questionnaire containing Patient Health Questionnaire-9 (PHQ-9) depression screening tool. Result. Of 84 patients who were eligible for the study, 32.2% of patients have depressive symptoms. Women (OR 0.001, 95% CI 0.12–0.87) and aphasic patients (OR 0.034, 95% CI 0.19–1.27) were more likely to have depressive symptoms. Conclusion. Depressive symptoms after stroke are common in Ethiopian patients. Our study demonstrates female and aphasic patients are more likely to screen positive for PSD. Hence, screening all poststroke patients with different screening tools is practical, and further studies are needed to assess the validity of these screening tools and also to assess PSD as a predictor of stroke outcome.

Full textAbstract:
Objectives The aim of this study was to elucidate the positional relationship between the courses of the angular veins and the facial muscles, and the possible roles of the latter as alternative venous valves. Methods The angular veins of 44 specimens of embalmed Korean adult cadavers were examined. Facial muscles were studied to establish their relationships with the angular vein, including the orbicularis oculi (OOc), depressor supercilii (DS), zygomaticus minor (Zmi), zygomaticus major (Zmj), and levator labii superioris (LLS). Results In the upper face of all specimens, the angular vein passed through the DS and descended to the medial palpebral ligament. In the midface, it passed between the origin of the levator labii superioris alaeque nasi (LLSAN) and the inferior OOc fibers. The vein coursed along the deep surface of the inferior margin of the OOc in all specimens. At the level of the nasal ala, the course of the angular vein was classified into three types: in type I it passed between the LLS and Zmi (38.6%), in type II it passed between the superficial and deep fibers of the Zmi (47.7%), and in type III it passed between the Zmi and Zmj (13.6%). In the lower face of all specimens, the angular or facial vein passed through the anterior lobe of the buccal fat pad. Conclusion This study found that the angular vein coursed along the sites where facial muscle contractions are assumed to efficiently compress the veins, likely controlling venous flow as valves. The observations made and analysis performed in this study will improve the understanding of the physiological function of the facial muscles as alternative venous valves.

Full textAbstract:
We have developed a series of aminoacetylenic isoindoline-1,3-dione compounds and showed their anti-inflammatory activities by reducing carrageenan-induced rat paw edema and modulating proinflammatory and anti-inflammatory cytokines. In the present study and due to efficacy reasons, we are exploring only two of these compounds, namely, ZM4 and ZM5, to reveal their analgesic activity and toxicity. Following oral administration, both compounds were effective in reducing significantly (P<0.05–0.001) acetic acid-induced writhing behavior, hot plate latency test, and formalin-induced paw licking time as antinociceptive indicators in mice and rats, respectively. Regarding the toxicity, the acute (20, 50, and 150 mg/kg) and repeated oral administration (10, 20, and 50 mg/kg) of these compounds for ten days did not produce any mortality and the compounds were considered well tolerated. However, repeated oral administration of 50 mg/kg of both compounds induced erythropoiesis by means of increasing significantly red blood cells, hemoglobin, and packed cell volume. Moreover, these compounds did not induce gastric lesions in the stomach of experimental animals at the doses that exhibited analgesic and anti-inflammatory activity compared to indomethacin as a positive control. The results indicate that ZM4 and ZM5 possess potential analgesic activity while being preliminarily safe and have minimal ulcerogenic activity.

Full textAbstract:
&lt;i&gt;Background:&lt;/i&gt; It has been four decades since the Human Immunodeficiency Virus (HIV) became a global public health issue; much has changed about the disease since then. The occurrence of renal impairment in HIV-infected individuals is associated with both increased morbidity and mortality. &lt;i&gt;Objective:&lt;/i&gt; The goal of this study was to assess the incidence of renal dysfunction and the variables associated with it in HIV-positive patients undergoing treatment at the ART clinics of Zewuditu Memorial Hospital (ZMH) and St. Paul&apos;s Millennium Medical College (SPHMMC) between April and August of 2021. &lt;i&gt;Methodology:&lt;/i&gt; A cross-sectional study was conducted to assess the association between impaired renal function and different factors among HIV-infected individuals. Data was collected from the medical charts of the patients in the anti-retroviral therapy (ART) clinic of respective hospitals. Variables with a p-value of &lt;0.25 on bivariate analysis were taken to Multivariable logistic regression to see the statistical significance and at &lt;0.05 statistical significance was declared. &lt;i&gt;Result: &lt;/i&gt;The total number of samples was 405, and all of them were included in the analysis. The magnitude of the renal dysfunction revealed in this study was 8.4% (95% Confidence Interval: 5.51 to 11.4). Multivariable logistic regression showed that being female (Adjusted Odds Ratio = 4.5; 95%CI: 1.94, 10.36), Baseline CD4 count less than 200, (AOR = 3.4; 95% CI:1.34, 8.70), and a history of opportunistic infection (AOR = 2.7; 95% CI: 1.02, 7.39) were significantly associated with the impaired renal function. &lt;i&gt;Conclusion:&lt;/i&gt; Routine monitoring of renal function, especially in patients with risk factors like female gender, low CD4 count, and history of opportunistic infections, is crucial. Promoting ART regimens containing TDF, early detection and prevention of opportunistic infections, and educating patients about regular CD4 count monitoring and timely treatment are essential for maintaining renal health.

Medicinal plants are used in traditional system of medicine to treat various diseases and many of these plants have been evaluated for their different pharmacological activities. Ziziphus mauritiana (ZM) (Rhamnaceae) is found wild and cultivated in many parts of India, Burma and Srilanka. Seeds of Ziziphus mauritiana have been reported to have sedative-hypnotic, hypotensive, antihypoxic, antihyperlipidemic and hypothermic activities. It is reported to contain minerals, alkaloids, flavonoids, sterols, tannins and saponins. Traditional medicine using herbal drugs exists in every part of the world. The major areas are Chinese, Indian and European traditions. The philosophies of these traditional medicines have some resemblance to each other but differ widely from modern western medicine. In view of the progress of western medicine not only new synthetic drugs but also herbal drugs have to fulfill the international requirements on quality, safety and efficacy. Herbal drugs have the advantage of being available for patients in the geographical area of the special traditional medicine. The development procedure of herbal drugs for world-wide use has to be different from that of synthetic drugs.

Full textAbstract:
A series of carbon with ZSM-5 mesoporous (ZMC) and Ni/ZMC ZSM-5 templates were synthesized and gravimetrically known its adsorption capacity to H2 gases. ZMC carbon was synthesized using a hard template method at a carbonation temperature of 900 oC with sucrose as a source of carbon. A mesoporous ZSM-5 template was synthesized by using a hydrothermal method at an aging and crystallization temperature of respectively 60oC and 150oC for as long as 24 hours. The characterized result of ZMC carbon using XRD powder has shown a diffracted pattern of amorphous carbon. Impregnating Ni with ZMC carbon each resulted in 5%, 15% and 25% of weight, which in turn also resulted in a diffractogram pattern of Ni/ZMC-5, Ni/ZMC-15, and Ni/ZMC-25, where each patterns were uniform and had no additional peaks. The results of SEM-EDAX showed that Ni had been successfully impregnated on the surface of ZMC carbon with a random morphology surface of ZMC carbon. The isothermal results of adsorption – desorption of N2 showed that the larger the Ni loading on the supporting ZMC carbon, the smaller the surface area of the ZMC specific carbon. The distribution of the pore size that was counted by using the BJH method, which was applied to all the samples, was as big as 3,8 nm. The adsorption capacity of H2 was measured by using the gravimetry method at ambient temperature for Ni/ZMC-5, Ni/ZMC-15, and Ni/ZMC-25, which each gave a weight percentage of 0,331%; 0,663% and 0,649% respectively, whilst the ZMC carbon has a weight of 2,18%.

Full textAbstract:
ABSTRACT zfh-1 is a member of the zfh family of proteins, which all contain zinc finger and homeodomains. The roles and mechanisms of action of most family members are still unclear. However, we have shown previously that another member of the family, the vertebrate ZEB protein, is a transcriptional repressor that binds E box sequences and inhibits myotube formation in cell culture assays. zfh-1 is downregulated in Drosophila embryos prior to myogenesis. Embryos with zfh-1 loss-of-function mutation show alterations in the number and position of embryonic somatic muscles, suggesting that zfh-1 could have a regulatory role in myogenesis. However, nothing is known about the nature or mechanism of action of zfh-1. Here, we demonstrate that zfh-1 is a transcription factor that binds E box sequences and acts as an active transcriptional repressor. When zfh-1 expression was maintained in the embryo beyond its normal temporal pattern of downregulation, the differentiation of somatic but not visceral muscle was blocked. One potential target of zfh-1 in somatic myogenesis could be the myogenic factor mef2. mef2 is known to be regulated by the transcription factor twist, and we show here that zfh-1 binds to sites in the mef2 upstream regulatory region and inhibits twist transcriptional activation. Even though there is little sequence similarity in the repressor domains of ZEB and zfh-1, we present evidence that zfh-1 is the functional homologue of ZEB and that the role of these proteins in myogenesis is conserved fromDrosophila to mammals.

A pragmatic approach to the treatment of infectious diseases with multicausal agents and prevention of the development of resistant isolates is the combination of herbal remedies with the first-line antimicrobial agents to which most of them have become resistant. This study evaluated the interactions between the ethanolic bark extract ofZiziphus mucronatawith known antimicrobial agentsin vitro. In this study, the results showed that varied zones of inhibitions (ZME—chloramphenicol (17–42 mm), ZME—amoxicillin (17–35 mm), ZME—tetracycline (17–36 mm), ZME—ciprofloxacin (20–41 mm), ZME—nalidixic acid (17–34 mm), and ZME—kanamycin (17–38 mm)) were produced by the antibacterial combinations. At the highest combined concentrations, 12 isolates (ZME—ciprofloxacin) > 10 isolates (ZME—chloramphenicol) = (ZME—kanamycin) > 6 isolates (ZME—amoxicillin) = (ZME—nalidixic acid) and 5 isolates (ZME—tetracycline) were inhibited with zones of inhibition greater than20±1.0 mm. Although the agar diffusion assay suggested that the interactions between the ethanolic extract ofZ. mucronataand the antibiotics were both synergistic and additive in nature, the fractional inhibitory concentration indices (FICI) showed that the interactions were synergistic (54.17%), additive (27.78%), indifferent (16.67%), and antagonistic (1.39%). While the fractional inhibitory concentration indices (FICIs) for synergism ranged between 0.00391 and 0.5, that of additivity ranged between 0.516 and 1.0, indifferences ranged between 1.062 and 3.0 and antagonistic interaction was 5.0. The synergistic effects implied that the antibacterial combinations would be more effective and useful in the treatment of multicausal and multidrug-resistant bacteria than a single monotherapy of either antibacterial agent.

ABSTRACTZwittermicin A (ZmA) is a hybrid polyketide-nonribosomal peptide produced by certainBacillus cereusgroup strains. It displays broad-spectrum antimicrobial activity. Its biosynthetic pathway inB. cereushas been proposed through analysis of the nonribosomal peptide synthetase (NRPS) and polyketide synthase (PKS) modules involved in ZmA biosynthesis. In this study, we constructed a bacterial artificial chromosome (BAC) library fromBacillus thuringiensissubsp.kurstakistrain YBT-1520 genomic DNA. The presence of known genes involved in the biosynthesis of ZmA in this BAC library was investigated by PCR techniques. Nine positive clones were identified, two of which (covering an approximately 60-kb region) could confer ZmA biosynthesis ability uponB. thuringiensisBMB171 after simultaneous transfer into this host by two compatible shuttle BAC vectors. Another previously unidentified gene cluster, namedzmaWXY, was found to improve the yield of ZmA and was experimentally defined to function as a ZmA resistance transporter which expels ZmA from the cells. Putative transposase genes were detected on the flanking regions of the two gene clusters (the ZmA synthetic cluster andzmaWXY), which suggests a mobile nature of these two gene clusters. The intact ZmA gene cluster was validated, and a resistance mechanism complementary to that forzmaR(the previously identified ZmA self-resistance gene) was revealed. This study also provided a straightforward strategy to isolate and identify a huge gene cluster fromBacillus.
