Full textAbstract:
Seven strains of shiitake mushroom [Lentinula edodes (Berk.) Pegler] produced spawn in culture vessels containing hardwood sawdust amended with YVMBS (yeast extract, multigrain oatmeal, brown sugar) broth within 35 to 45 days after mycelia inoculations. Under greenhouse conditions, shiitake basidiocarps (mushroom fruit) appeared from 1 to 3 months after spawn inoculations of the hardwood sawdust amended with YVMBS broth. The shiitake mushroom strains LE2, LE1, LE6, and LE5 had 10.4, 7.3, 2.5, and 1.6 times more fresh harvested basidiocarps, respectively, on the amended hardwood sawdust compared to the controls. The amount of basidiocarps produced by the shiitake strains LE3, LE4, and LE7 was the same on both hardwood sawdust treatments. The basidiocarps of LE1, LE2, LE3, LE4, and LE5 were averaged 5 inches (12.7 cm) in diameter, however, the basidiocarps of LE6 and LE7 were averaging only 2 inches (5.1 cm) in diameter. The only pests of the shiitake basidiocarps in the greenhouse were slugs, but they were easily controlled by applying table salt. The start up cost of inoculating 100 shiitake spawn blocks on hardwood sawdust on one bench in the greenhouse was $77. The start up cost of inoculating shiitake spawn on 100 logs was $1,329.75. In 1 year, shiitake strains LE1, LE2, LE5, and LE6 produced 19.5, 20.2, 7.9, and 4.5 lb (8.8, 9.2, 3.6, and 2.0 kg), respectively, of harvested fresh basidiocarps on amended hardwood sawdust in the greenhouse. The mushrooms retail for $3.20 to $4.20/lb ($7.05 to $9.26/kg). The use of the hardwood sawdust amended with YVMBS broth for shiitake production in the greenhouse has considerable economic potential for shiitake mushroom growers.

Full textAbstract:
We investigated the performance of single-structured light-emitting electrochemical cell (LEC) devices with Ru(bpy)3(PF6)2 polymer composite as an emission layer by controlling thickness and heat treatment. When the thickness was smaller than 120–150 nm, the device performance decreased because of the low optical properties and non-dense surface properties. On the other hand, when the thickness was over than 150 nm, the device had too high surface roughness, resulting in high-efficiency roll-off and poor device stability. With 150 nm thickness, the absorbance increased, and the surface roughness was low and dense, resulting in increased device characteristics and better stability. The heat treatment effect further improved the surface properties, thus improving the device characteristics. In particular, the external quantum efficiency (EQE) reduction rate was shallow at 100 °C, which indicates that the LEC device has stable operating characteristics. The LEC device exhibited a maximum luminance of 3532 cd/m2 and an EQE of 1.14% under 150 nm thickness and 100 °C heat treatment.

Utilizou-se o delineamento experimental inteiramente casualizado em parcela subdividida, adotando-se nas parcelas dois tipos de água para a irrigação (água potável – AP e água residuária – AR) e nas subparcelas 7 níveis de adubação nitrogenada, assim descritos: T1, sem adubação nitrogenada; T2, 80 kg ha-1 de N via ureia; T3, 40 kg ha-1 de N via ureia + 40 kg ha-1 de N via LEC; T4, T5, T6 e T7 corresponderam à 80, 120, 160 e 200 kg ha-1 de N via LEC, respectivamente. A irrigação com água residuária na ausência de adubação nitrogenada promoveu incrementos de 36, 100, 48 e 77% na massa seca da parte aérea (MSPA), número de perfilhos (NP), número de espigas por planta (NE) e no rendimento de grãos (RG), respectivamente. O uso conjunto de AR e doses de N acima de 80 kg ha-1 via LEC no solo, promoveu decréscimos no comprimento de espiga (CE), MSPA e RG. Os resultados apontam para a substituição de 100% da adubação nitrogenada química (dose de 80 ka ha-1 de N), pelo equivalente em N via LEC (100% lodo), sem prejuízos à cultura do trigo.

S.ORGANIC COMPOUND FERTILZER AND WASTEWATER IN THE DEVELOPMENT OF WHEAT IRRIGATED BY DRIPPING 2 ABSTRACT The objective of this study was to evaluate the effect of organic compound fertilizer use (composted sewage sludge - CSS) in wheat plants irrigated with wastewater from the output of a sewage treatment plant. Completely randomized design was used in a split plot, adopting in the plots two types of water for irrigation (drinking water - DA and wastewater - WW) and in subplots seven nitrogen fertilization levels, described as follows: T1 without nitrogen fertilization; T2, 80 kg ha-1 of N of urea; T3, 40 kg ha-1 N of urea + 40 kg ha-1 N of CSS; T4, T5, T6 and T7 corresponded to 80, 120, 160 and 200 kg ha-1 N of CSS, respectively. Irrigation with WW promoted increments of 36, 100, 48 e 77% of dry matter (DM), number of tillers (NT), number of spikes per plant (NS) and grain yield per plant (GY), respectively. The use of wastewater with doses of nitrogen above 80 kg ha-1 from composed sewage sludge, promoted decreases in spike length, dry mass and grain yield. The results point to the substitution of 100% of the chemical nitrogen fertilization (dose of 80 ka ha-1 of N), by the equivalent in N from CSS (100% sludge), without damages to the wheat crop. Keywords: wastewater, sludge, compound, nitrogen, irrigation.

Full textAbstract:
The article is devoted to the study of delayed (post-traumatic) stress caused by different types of stressful situations (death of a loved one, life-threatening diseases, traffic accidents, situations of physical and emotional violence) during early adulthood, the analysis of specific psychological markers of its intensity. The study involved 509 people (232 men and 277 women) aged 17 to 35 years (Me = 21; SD = 4,3). Methods: Posttraumatic Stress Disorder Checklist (PCL-5) in the Russian-language adaptation by N. V. Tarabrina and co-authors for the diagnosis of stressful events and their psychological consequences; the list of stress situations contained in the Life Events Checklist (LEC-5) for DSM-5; the Symptom Check List-90-r-Revised (SCL-90-R) technique in the Russian-language adaptation by N. V. Tarabrina and co-authors was used to evaluate psychopathological symptoms. It has been shown that the most severe in intensity posttraumatic stress causes situations that pose a threat to the physical and psychological well-being of a person at the same time (violence and life-threatening disease). Taking into account the level of mental trauma and the type of stressor, an analysis of a number of features of psychopathological symptoms was carried out. The results of the study made it possible to identify markers of severe post-traumatic stress, which were indicators of violation of contact with reality, expressed in distancing a person from the surrounding reality, distrust of the world, suspicion, phobic anxiety.

Full textAbstract:
The technical and financial feasibility of small-scale distributed Concentrating Solar Thermal Power (CSP) systems for urban areas in Johannesburg, South Africa, is investigated. The University of the Witwatersrand (Wits), located in central Johannes-burg, is used as the basis of a case study for the im-plementation of these systems. A number of proven CSP technologies were identified and a technology screening was performed to identify suitable technologies for possible implementation, for a reference output of 120 kW(e). From these, a number of systems were chosen for more detailed evaluation and the hourly energy production of these systems was analysed, using local weather data. The Compound Linear Fresnel Reflector system (CLFR) proved to be most suitable because of the space and cost benefits it offers. Systems that integrate organic Rankine cycles (ORC) as well as thermal storage and hybridisation were also investigated. The levelised cost of electricity (LEC) was predicted to be between R4.31 and R3.18 per kWh. Currently these technologies cannot compete financially with the price of local, fossil produced electricity, but with the increase in electricity tariffs and demand for clean reliable power CSP technologies, may become competitive in distributed generation systems in urban areas.

Full textAbstract:
324 Background: Blood-based-inflammation-markers (BBIM) and Body Mass Index (BMI) have been associated with overall survival (OS) in a number of cancers. Inflammation and obesity have biological interactions. We evaluated the role of Neutrophil-to-Lymphocyte-Ratio (NLR), Platelet-to-Lymphocyte-Ratio (PLR) and Systemic-Inflammation-Index (SII) in conjunction with BMI as predictors of OS in localized/locally-advanced-esophageal cancer (LEC/LAEC). Methods: LEC/LAEC patients treated from 2006-2014 had the following variables analyzed both as continuous and categorical: BMI (low <25 kg/m2, high ≥25 kg/m2), NLR (low <4, high ≥4), PLR (low <232, high ≥232), and SII (low <1375, high ≥1375), with OS. Univariate (UVA) and Multivariate analysis (MVA) were analyzed using Cox regression (adjusted hazard ratios, aHR; 95% Confidence Intervals, CI). MVA models of OS were built, assessing different categorical combinations of BBIM factors with and without BMI. Results: Of 411 pts, 79% were males, median age was 63.5 years, 67% were adenocarcinomas; Stage I/II/III: 14%, 28%, 59%; Median BMI was 26.5kg/m2 and BMI distribution was: 3% underweight, 40% normal weight, 37% overweight and 20% obese. After a median follow-up of 87 months, 204 pts recurred, and 257 died. In MVA, BMI alone had no impact on OS (aHR 0.89, CI 0.7-1.1, p=0.15); individually as continuous variables, higher SII (p=0.03) and higher NLR (p=0.006) were inversely associated with OS whereas higher PLR was not (p=0.10). In an MVA of categorical combinations of BMI and BBIM on OS, patients in the high-BMI/low-PLR group were at lower risk of death when compared to all other groups (aHR=0.65, 95%CI:0.5-0.8, p=0.007). Similar non-statistically significant trends were shown when SII and NLR were individually combined with BMI (aHR=0.77, 95%CI:0.6-1.0, p=0.09; aHR=0.74, 95%CI:0.5-1.0, p=0.05, respectively). Conclusions: Our results suggest that in LEC/LAEC pts, high BMI and low PLR together are associated with improved OS when compared to pts with low BMI and/or high PLR. NLR and SII alone were associated with OS. Further studies evaluating the underlying mechanisms of BBMI, in particular PLR and inflammation/obesity are warranted.

Full textAbstract:
Two field experiments were carried out at the Experimental Farm of Gemmeiza Agriculture Research Station, Agricultural Research Center (ARC), Egypt after 2018 and 2019 summer growing seasons to determine the effect of intercropping pattern of yellow maize hybrid (single cross 168: &ldquo;SC 168&rdquo;) with watermelon pulp at three plant distributions (20 cm between hills and one plant/hill, 40 cm between hills and two plants/hill and 60 cm between hills and three plants/hill) and different levels of nitrogen fertilizer (25, 50, 75 and 100% of the recommended dose &ldquo;120 kg N fad-1&rdquo;) as well as their interactions on maize and watermelon pulp growth, yield and its attributes as well as competitive relationships and yield advantages. The experiments were carried out in split-plot design with four replicates. The main-plots were assigned to plant distributions of maize, the sub-plots were allocated to levels of nitrogen fertilizer for maize. The obtained results showed that planting maize plants on one side of terraces of 140 cm width with 20 cm between hills and leaving one plant/hill and planting watermelon pulp on the other side of the terraces produced the highest values of plant height, ear height, number of kernels row-1, 100-kernel weight and grain yield fad-1, at the same time the lowest values of ear leaf area, ear length, ear diameter and number of rows ear-1 of maize as well as the lowest values of growth, yield and its attributes of watermelon pulp during the both seasons. Mineral fertilizing maize plants with 75% of the recommended dose (90 kg N/fad) and watermelon pulp with the recommended dose produced the highest values of all studied growth characters, yield and its attributes of maize and watermelon pulp in both seasons. The highest values of land equivalent ratio (LER), relative crowding coefficient (RCC), area time equivalent ratio (ATER), land equivalent coefficient (LEC), aggressivity index (AI), monetary advantage index (MAI), actual yield (L.E.) of watermelon, Total income (L.E.) and economic return (L.E.) were obtained from planting maize plants on one side of terraces of 140 cm width with 60 cm between hills and leaving three plants/hill and planting watermelon pulp on the other side of the terraces besides fertilizing maize plants with 75% of the recommended dose (90 kg N/fad) and watermelon pulp with the recommended dose in both seasons. It can be recommended that planting maize on 60 cm between hills and leaving three plants/hill and planting watermelon pulp on the other side of the terraces besides fertilizing maize plants with 90 kg N/fad and watermelon pulp with the recommended dose to obtain the maximum values growth, yield and its attributes of watermelon pulp and competitive relationships and yield advantages of both crops under the climates conditions of Middle Delta, Egypt.

Full textAbstract:
Hepatic stellate cells (HSC) and liver endothelial cells (LEC) migrate to sites of injury and perpetuate alcohol-induced liver injury. High-mobility group box 1 (HMGB1) is a protein released from the nucleus of injured cells that has been implicated as a proinflammatory mediator. We hypothesized that HMGB1 may be released from ethanol-stimulated liver parenchymal cells and contribute to HSC and LEC recruitment. Ethanol stimulation of rat hepatocytes and HepG2 cells resulted in translocation of HMGB1 from the nucleus as assessed by Western blot. HMGB1 protein levels were increased in the supernatant of ethanol-treated hepatocytes compared with vehicle-treated cells. Migration of both HSC and LEC was increased in response to conditioned medium for ethanol-stimulated hepatocytes (CMEtOH) compared with vehicle-stimulated hepatocytes (CMVEH) ( P < 0.05). However, the effect of CMEtOH on migration was almost entirely reversed by treatment with HMGB1-neutralizing antibody or when HepG2 cells were pretransfected with HMGB1-siRNA compared with control siRNA-transfected HepG2 cells ( P < 0.05). Recombinant HMGB1 (100 ng/ml) also stimulated migration of HSC and LEC compared with vehicle stimulation ( P < 0.05 for both HSC and LEC). HMGB1 stimulation of HSC increased the phosphorylation of Src and Erk and HMGB1-induced HSC migration was blocked by the Src inhibitor PP2 and the Erk inhibitor U0126. Hepatocytes release HMGB1 in response to ethanol with subsequent recruitment of HSC and LEC. This pathway has implications for HSC and LEC recruitment to sites of ethanol-induced liver injury.

Abstract Background and study aims A newly developed peroral cholangioscopy (POCS) system, SpyGlassDS has high maneuverability. This study aimed to evaluate acceptability of the accuracy of SpyGlassDS accompanied by simultaneous POCS-guided biopsy compared with that of a traditional POCS scope, CHF-B260, to diagnose the lateral extent of extrahepatic cholangiocarcinoma (LEC). Patients and methods Patients who underwent surgical resection after preoperative examinations to diagnose LEC were evaluated. POCS by CHF-B260 was performed if there was discrepancy between preceding fluoroscopy-guided biopsy findings and other examinations between January 2004 and September 2015 (group A, n = 56); and POCS plus POCS-guided mapping biopsy by SpyGlassDS was performed in all surgical candidates between October 2015 and December 2017 (group B, n = 20). The main outcome measure was the accuracy of overall preoperative diagnosis (OPD) of LEC defined based on all examinations, including POCS. Results Accuracy of OPD for the liver side and the ampullary side was 93 % and 100 %, respectively, in group A, and 84 % and 100 %, respectively, in group B (P = 0.37 for the liver side; P, not available for the ampullary side). Diagnostic accuracy of simple optical evaluation by POCS for the liver side and the ampullary side was 83 % and 100 %, respectively, in group A, and 58 % and 88 %, respectively, in group B (P = 0.29 for the liver side; P = 0.40 for the ampullary side). Conclusions POCS by SpyGlassDS was found to be acceptable and could be a standard approach for diagnosis of LEC.

Full textAbstract:
The Lac des Iles Complex is a late Archean, mafic to ultramafic complex that is host to 20.4 × 106 t Pt, Pd, and Au mineralization with an average grade of 6.34 g/t platinum-group elements (PGE). The 30 km2 complex, located in the Wabigoon Subprovince, consists of several coalescing mafic to ultramafic intrusive centers. The complex is emplaced into early gneissic tonalite and is contemporaneous with late granitoids.The magmatic evolution of the complex reflects the emplacement of multiple pulses of previously fractionated magma, some of which underwent subsequent in situ fractionation. Distinct magma sequences are recognized on the basis of intrusive relationships, differences in the cumulus minerals, crystallization order, and trace-element chemistry. These sequences are (1) hornblende gabbro, (2) gabbro and gabbronorite, and (3) ultramafic. Where there is evidence of intrusive relations, the most primitive sequences are emplaced late and occur toward the north end of the complex. Microprobe analyses indicate the following compositional ranges of mineral phases within the complex: olivine–Fo84–76, orthopyroxene—En82–67Fs15–30Wo2–3, and clinopyroxene—En53–46Fs3–12Wo41–51. Cyclic layering is developed only in the northern ultramafic part of the complex where several cycles of mesocumulate- to adcumulate-textured wehrlite, clinopyroxenite, and websterite are identified.Although the parental magma compositions are not well constrained, model calculations using major-element and rare-earth-element (REE) contents of cumulus phases and adcumulate rocks indicate that the parental magmas had mol MgO/(MgO + FeO) ranging from at least 0.61 to 0.54 and had fractionated REE abundances with CeN/YbN of approximately 5.0. Mineral chemistry and crystallization sequences indicate that the ultramafic and gabbroic parts of the complex had tholeiitic basalt parental magmas of picritic and high-alumina affinities, respectively.The major PGE mineralization at Lac des Iles occurs in the Roby Zone along the interface between the gabbro and gabbronorite in the southern part of the complex. This interface has been intruded by a sheet of pyroxene cumulate, which is probably part of the ultramafic sequence. The PGE sulphide mineralization in the Roby Zone is associated with disseminated chalcopyrite, pyrrhotite, pentlandite, pyrite, and altered silicates in (1) the pyroxene cumulate sheet, (2) the mixed gabbro–gabbronorite, and (3) the gabbroic pegmatite dikes and breccia zones. Cl-rich apatite and monazite are accessory phases associated with PGE mineralization PGE occurrences are also present within sulphide-bearing orthopyroxene–clinopyroxene cumulates in the northern ultramafic part of the complex. The Roby Zone mineralization is localized by mixing the PGE and sulphide-rich gabbronorite and pyroxene cumulates with the volatile-rich gabbro. The PGE are redistributed by late magmatic volatile activity, which generated mineralized gabbroic pegmatites and breccia zones.

Full textAbstract:
To clarify the roles of lymphatic endothelial cells (LEC) in the regulation of endothelial constitutive nitric oxide synthase (ecNOS) expression, we examined the effects of shear stress on ecNOS immunohistochemical staining and mRNA and protein expression in human LEC as well as on ATP release from these cells. Shear stress at 0.5 or 1.0 dyn/cm2 increased ecNOS immunohistochemical staining and ecNOS mRNA and protein expression in cultured LEC. The same strength of shear stress produced a significant release of ATP from the LEC. Exogenous ATP ranging in concentration from 10−9 to 10−6 M produced a significant increase in ecNOS immunohistochemical expression in a dose-dependent manner. The increase in ecNOS expression mediated by 10−6M ATP was significantly reduced by 10−5 M suramin. Suramin (10−5 M) caused a significant reduction in the shear stress-mediated increases in ecNOS immunohistochemical staining and mRNA expression. The shear stress-mediated increases in ecNOS expression were significantly reduced by 3 mM tetraethylammonium, 10−4 M apamin, 10−9 M iberiotoxin, 10−5 M 2-aminoethoxydephenyl borate, or 10−5M xestospongin C, but not 10−5 M glybenclamide or 10−5 M nifedipine. The shear stress-mediated increases in ecNOS expression were significantly potentiated by pinacidil or NS1619 in a dose-dependent manner. The immunohistochemical expression of small- (SKCa) and big-conductance (BKCa) Ca2+-activated K+ channels was confirmed on the surfaces of human LEC. These findings suggest that shear stress produces a significant release of ATP from LEC, which activates the purinergic P2X/2Y receptor, thereby facilitating ecNOS mRNA and protein expression through inositol 1,4,5-trisphosphate-mediated release of intracellular Ca2+ ions and the activation of Ca2+-activated K+ channels in LEC.

Classification systems are published primarily in the book form, for various purposes and in different versions. They are identified by the number or year of publication. The authors propose another variant of maintaining classification systems, i.e. in the card format.The authors discuss the issues of presenting classification schedules of popular classification systems on the Internet with special focus on their applications. They explain why privately owned classification systems, like Dewey Decimal Classification (DDC) and Universal Decimal Classification (UDC), are not published on the Internet, while the systems supported by government organizations (e.g. national libraries) are traditionally published openly. The authors provide the example of the Library of Congress Classification (LCC), which is the United States’ National Classification System and which is published on open access. The project of the open presentation of the Library-Bibliographical Classification (LBC) in several versions supplemented with indices on the website of the Russian State Library (RSL) is described in more detail. The possibilities for their use are analyzed.

É cada vez mais comum a adição de componentes orgânicos aos substratos em viveiros florestais, com o objetivo de potencializar seus atributos biológicos, químicos e físicos. Entre esses componentes destaca-se o lodo de esgoto que, após passar por processo de estabilização, torna-se um componente rico em matéria orgânica, podendo ser utilizado na agricultura, e em viveiros florestais. O trabalho teve como objetivo analisar o comportamento da espécie em diferentes composições de substratos e lâminas de irrigação. Utilizaram-se 5 formulações distintas de substrato compostas por substrato comercial (SC) e lodo e esgoto compostado (LEC). Avaliaram-se simultaneamente 3 lâminas de água, perfazendo um total de 300 mudas no estudo. Os parâmetros analisados foram: altura de planta, diâmetro do coleto, número de folhas, massa seca de parte aérea e raiz. Observou-se que os melhores tratamentos consistiram nas seguintes formulações: S1 (100% LEC), S2 (25% SC + 75% LEC), e S3 (50% SC + 50% SC). Mostrou-se que, a partir do LEC puro, houve melhor desenvolvimento das mudas, expressando um aporte com o aumento no diâmetro do coleto, altura da planta, maior crescimento inicial e desenvolvimento radicular, ou seja, além do potencial como fertilizante, o LEC atua como condicionador de atribuições físicas, química e biológicas necessárias às mudas. As diferentes lâminas de irrigação não apresentaram influência significativa em nenhum dos parâmetros avaliados.

Abstract Background and study aims Endoscopic ultrasound (EUS)-guided fine-needle aspiration (EUS-FNA) has limitations of inadequate sampling and false-negative results for malignancy. It has been performed using conventional smear (CS) cytology with rapid on-site evaluation (ROSE) with reasonable diagnostic accuracy. An alternative to ROSE is liquid-based cytology (LBC). Commonly used LBC techniques include precipitation-based (SurePath™) and filtration-based (ThinPrep®, CellPrep®). Data regarding the diagnostic efficacy of LBC compared with CS are limited. Methods Multiple databases were searched through March 2020 to identify studies reporting diagnostic yield of EUS-guided CS and LBC in pancreatic lesions. Pooled diagnostic odds and rates of performance for the cytologic diagnoses of benign, suspicious, and malignant lesions were calculated. Diagnostic efficacy was evaluated by pooled rates of accuracy, sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV). Results Nine studies with a total of 1308 patients were included in our final analysis. Pooled diagnostic odds of CS cytology were 1.69 (CI 1.02–2.79) and 0.39 (CI 0.19–0.8) for malignant lesions when compared to filtration-based and precipitation-based LBC techniques, respectively. For CS, precipitation-based and filtration-based LBC, pooled diagnostic accuracy was 79.7 %, 85.2 %, 77.3 %, sensitivity was 79.2 %, 83.6 %, 68.3 %, and specificity was 99.4 %, 99.5 %, 99.5 %, respectively. Conclusions The precipitation-based LBC technique (SurePath™) had superior diagnostic odds for malignant pancreatic lesions compared with CS cytology in the absence of ROSE. It showed superior accuracy and sensitivity, but comparable specificity and PPV. Diagnostic odds of CS cytology in the absence of ROSE were superior to the filtration-based LBC technique (ThinPrep®, Cellprep®) for diagnosing malignant pancreatic lesions.

Abstract The lymphatic system plays an important physiological role in vascular and immune homeostasis. Lymphatic vessel function is implicated in a number of pathological conditions including tumor metastasis and impaired wound healing. The identity and origin of lymphatic endothelial precursors is poorly understood. Previously we have shown that adult bone marrow-derived, hematopoietic stem cells (HSCs, c-kit+, Sca-1+, lineage−) can differentiate into functional blood vascular endothelial cells. Given the close relationship between the blood and lymphatic vascular systems, we have investigated whether HSCs also give rise to lymphatic endothelial cells (LEC). GFP+ HSCs were transplanted into lethally irradiated (1200 cGy) recipient mice. Donor-derived LEC expressing lymphatic endothelial markers including LYVE-1 and VEGFR3 were clearly distinguished from hematopoietic cells by the absence of CD45 and F4/80 expression. Deconvolution microscopy confirmed the co-localization of donor and LEC marker expression in individual cells. Transplanted HSCs gave rise to LEC in the liver, gut, gastric and kidney. Donor-derived LEC were detected in 2.4% of liver lymphatic vessels at 4 weeks and persisted for at least 12 months (mean of 3.4%). The self-renewal capacity of HSC-derived lymphatic progenitor cells was demonstrated by serial transplantation. The contribution of these progenitors to tumor lymphatics was evaluated. Transplantation of HSCs into young Min−/− mice resulted in the incorporation of donor-derived LEC into the lymphatics of intestinal adenomas that spontaneously develop in these mice. In addition, CD45+F4/80+ leukocytes were detected in the vessel lumens indicating that these are functional tumor lymphatic vessels. Finally, to determine if LEC progenitors contribute to lymphatic vessels in the absence of radiation injury or tumorigenesis, a parabiosis model was evaluated. Donor-derived LEC were detected in parabiotic mice at a frequency similar to that observed for donor-derived blood vascular endothelial cells. This finding suggests that circulating progenitor cells contribute to lymphangiogenesis during steady-state conditions. Our results indicate that hematopoietic stem cells have the potential to contribute to lymphatic endothelium and therefore HSC-derived progenitors may be potential therapeutic targets for hematopoietic and lymphatic disease.

Full textAbstract:
The southernmost site where permafrost has been located in the QuebecLabrador peninsula is in a peatland on the subalpine summit of Lac des Cygnes Mountain (47°41'N, 70°36'W). Because of the thickness of its peat deposit, this site contains rich ecological information about the history of the peatland and its surrounding subalpine environment. We conducted a detailed macrofossil analysis to reconstruct the 6000-year history of the peatland. In general, the development of the Lac des Cygnes Mountain peatland has followed the classic succession of rich fen poor fen bog found in other peatlands in subarctic, boreal, and temperate environments. An abrupt decline in all tree macrofossils ca. 4000 BP suggests that a major deforestation event occurred on the summit of Lac des Cygnes Mountain. The exact cause of this deforestation event is unknown, but fire is a possible factor. The lack of absolute chronological resolution near the top of the macrofossil record precludes proper dating of permafrost inception, but the balance of evidence appears to indicate that the permafrost is modern.

Full textAbstract:
The effects of metabolic and respiratory alkalosis (MALK and RALK) on intracellular strong ion concentrations ([ion]i) and muscle to blood ion fluxes were examined at rest and during 5 min of intense, intermittent tetanic stimulation in the isolated, perfused rat hindlimb. Compared with the control (C), perfusion of resting skeletal muscle during MALK and RALK significantly increased [Cl−]i and [Na+]i, and RALK significantly lowered [K+]i; these changes, however, did not affect initial hindlimb force production. In both resting and stimulated muscle, the intracellular ion changes corresponded to appropriate perfusate to muscle ion fluxes. At rest, changes in slow-twitch soleus were greater than in fast-twitch white gastrocnemius (WG), but stimulation-induced changes in [Lac]i and [K+]i were greater in WG. At the end of stimulation [K+]i and [Mg2+]i had decreased less in MALK than in C and RALK, particularly in plantaris and WG muscles. Compared with C, the muscle to perfusate flux of Lac− increased by 37% in MALK and 27% in RALK. This was associated with significantly less Lac− accumulation in all muscles in MALK than in RALK, which, in turn, had significantly less lactate than C. Lactate efflux from contracting skeletal muscle was significantly correlated with an uptake of Cl− by muscle. It is concluded that extracellular alkalosis alters skeletal muscle intracellular ionic composition and increases Lac− efflux from skeletal muscle. In agreement with other studies, lactate release appears to occur by both ionic and molecular transport processes. Alkalosis had no apparent effect on muscle performance with this preparation.Key words: acid–base, skeletal muscle, potassium, lactate, ion transport.

Full textAbstract:
The objective of this study was to compare landform element complexes (LEC) and soil series as discrete management units for variable rate N fertilizer application. Crop response attributes including grain yield, and grain protein concentration were studied in ten intensively sampled transects in an undulating glacial till soil-landscape near Miniota, Manitoba. In 1997, a year with growing season precipitation 37% below average, median grain yield tended to increase with both N fertilizer and with convergent character in the landscape (upper < mid < lower). Varcoe soils, located predominantly within the lower LEC, were generally more productive than Newdale soils. Grain protein concentration increased with N fertilizer, but tended to decrease with convergent character in the landscape (upper > mid > lower), and was lowest in the Varcoe series. In 1998, growing season precipitation was 62% above average. Grain yield responses to N fertilizer were greater, due in part to declining N fertility in the check and 45 kg ha–1 treatments. Trends among LEC were opposite to those in 1997, as median grain yield estimates tended to decrease with convergent character in the landscape (upper > mid > lower). Grain yield was modeled as a function of estimated plant-available N supply within each LEC and soil series. Modeled 1997 grain yield maxima were 2077, 2261 and 2485 kg ha–1 in the upper, mid and lower LEC. Estimated plant-available N supply at the yield maxima were 89, 130 and 130 kg N ha–1, respectively. In 1998, the relative order of modeled maxima among LEC was reversed. Grain yield of 2501, 2355 and 2227 kg ha–1 were predicted in the upper, mid and lower LEC. Estimated plant-available N supply at the yield maxima were 146, 142 and 154 kg N ha–1, correspondingly. In 1997, plateau yields were 2379, 2495 and 2325 kg ha–1 for Newdale, Varcoe and Angusville series, respectively, where the Varcoe series responded most strongly to estimated plant-available N supply. The corresponding estimated plant-available N supply values at the modeled maxima were 195, 139 and 110 kg ha–1. In 1998, plateau yields were 2343, 2253 and 2285 kg ha–1 for Newdale, Varcoe and Angusville series, respectively. The corresponding estimated plant-available N supply values at the modeled maxima were 136, 148 and 155 kg ha–1. Successful variable-rate fertilization by LEC or soil series will require long-term empirical study to establish risk-based grain yield-N relationships, and to determine if an economic advantage over conventional fertilization practices exists. Key words: Variable-rate fertilization, nitrogen, wheat yield, grain protein concentration, soil-landscape

Aims: To evaluate Liquid Based Cytology (LBC) diagnostic performance compared with Conventional Pap Smear (CPS) for cervical cancer screening and to compare the sensitivity and specificity of the two cytology methods with gold standard cervical biopsy.
 Methods: This is a hospital based cross-sectional study conducted from April 2017 to April 2018 in 110 sample randomly selected at gynecology OPD in Paropakar Maternity and Women’s Hospital. Paired samples (CPS and LBC) were taken from the same patient. Abnormal epithelial lesion detected in LBC and CPS was sent for biopsy. Bethedsa reporting system was followed and data analyzed in terms of diagnostic accuracy.
 Results: LBC vs CPS for satisfactory report was 96.4% vs 91.8% while unsatisfactory was 3.6% vs 1.8% (p=0.02). The detection of premalignant lesions was ASCUS 2.7%, HSIL 4.5%, ASCUS-H 1.8% and LSIL 0.9% by LBC while by CPS- ASC-US 0.9%, HSIL 3.6%, LSIL 1.8% and ASC-H 0.9% were detected. The sensitivity and specificity of LBC vs CPS was 100% vs 88% and 81.8% vs 99% respectively. The positive predictive and negative predictive value of LBC vs CPS was 81.8% vs 88% and 100% vs 99% respectively.
 Conclusions: Cell pick-up was satisfactory in both LBC and CPS. The sensitivity and positive predictive value of CPS is similar whereas the positive predictive value of LBC is less than its sensitivity. Cervical cancer screening with CPS is effective alternative over LBC by its cost and level of accuracy.

10028 Background: Latino advanced cancer patients are less likely to engage in advance care planning, use hospice services, and receive end-of-life (EOL) care in line with their preferences compared to non-Latino advanced cancer patients. Little is known about how immigration status influences preference for life-extending care (LEC) at the EOL. Methods: Data were derived from two sequential multi-institutional, longitudinal cohort studies of patients with advanced cancer recruited from 2002 – 2008 (Coping with Cancer I [CwC-1]) and 2010 – 2015 (Coping with Cancer II [CwC-2]). Multiple logistic regression analysis was used to estimate effects of immigrant status and CwC cohort among Latinos, and effects of ethnicity and CwC cohort among US-born Latinos and non-Latino whites, on preference for LEC at the EOL. Results: Of the 760 studied cancer patients, 661 were US-born non-Latino (US non-L), 34 were US-born Latino (USL) and 65 were Latino immigrants (LI). LI were less educated (mean years of education: 7.8 years) than USL (11.1 years), who were in turn less educated than US non-L (13.7 years). Far fewer LI had insurance compared to USL (18.5% vs. 64.7%, respectively; p < 0.001), and fewer USL had insurance compared to US non-L (64.7% vs. 81.4%, respectively; p = 0.017). Within CwC-2, LI had higher odds of preferring LEC over comfort care compared to USL (adjusted odds ratio [AOR] = 9.4; 95% CI: 1.2, 72.4), and USL had lower odds of preferring LEC compared to US non-L (AOR = 0.3; 95% CI: 0.1, 1.0). LI from CwC-2 had higher odds of preferring LEC compared to LI from CwC-1 (AOR = 11.4; 95% CI: 2.7, 48.4), but there was no difference between USL from CwC-2 and USL from CwC-1. US non-L from CwC-2 had higher odds of preferring LEC compared to US non-L from CwC-1 (AOR = 3.9; 95% CI: 2.6, 5.9). Within CwC-1, there was no difference in LEC preference between LI and USL, nor between USL and US non-L. Conclusions: Immigrant status has a strong effect on preference for life-extending care among the more recent cohort of Latino cancer patients. Preference for life-extending care appears to have increased significantly over time for Latino immigrants, but remained unchanged for US-born Latinos. Latino immigrants may increasingly want life-extending care near death.

Utilizou-se o delineamento inteiramente casualizado, no esquema de parcelas subdivididas, com 10 repetições. Avaliaram-se sete níveis de adubação nitrogenada (subparcela) distribuídos em duas parcelas experimentais, representadas pela irrigação com AP e AR, sendo assim definidos: T1 = sem adubação nitrogenada no solo; T2 = 100% de adubação nitrogenada química; T3 = 50% de adubação nitrogenada química + 50% de adubação nitrogenada via lodo de esgoto compostado (LEC); T4, T5, T6 e T7 corresponderam à 100, 150, 200 e 250% de adubação nitrogenada via LEC, respectivamente. Os resultados indicam a possibilidade de substituição da adubação nitrogenada química, 80 kg ha-1 de N, pelo equivalente em LEC, sem prejuízos à cultura. Em solo não adubado com N, a irrigação com AR de esgoto tratado foi benéfica ao trigo, proporcionando incremento de 60% no número de grãos por planta.

Abstract Background Cardiopulmonary arrests are rare, high-stakes events that benefit from using crisis resource management (CRM). Simulation-based education with deliberate practice can promote skill acquisition. Objective We assessed whether using simulation-based education to teach CRM would lead to improved performance, compared to a lecture format. Methods We tested third-year internal medicine residents in simulated code scenarios. Participants were randomly assigned to simulation-based education with deliberate practice (SIM) group or lecture (LEC) group. We created a checklist of CRM critical actions (which includes announcing the diagnosis, asking for help/suggestions, and assigning tasks), and reviewed videotaped performances, using a checklist of skills and communications patterns to identify CRM skills and communication efforts. Subjects were tested in simulated code scenarios 6 months after the initial assessment. Results At baseline, all 52 subjects recognized distress, and 92% (48 of 52) called for help. Seventy-eight percent (41 of 52) did not succeed in resuscitating the simulated patient or demonstrate the CRM skills. After intervention, both groups (n = 26 per group) improved. All SIM subjects announced the diagnosis compared to 65% LEC subjects (17 of 26, P = .01); 77% (20 of 26) SIM and 19% (5 of 26) LEC subjects asked for suggestions (P &lt; .001); and 100% (26 of 26) SIM and 27% (7 of 26) LEC subjects assigned tasks (P &lt; .001). Conclusions The SIM intervention resulted in significantly improved team communication and cardiopulmonary arrest management. During debriefing, participants acknowledged the benefit of the SIM sessions.

Full textAbstract:
The article is devoted to studying the effect of liquid melt treatment with a substance having high affinity with hydrogen – lead-base silumin. Taking into account that gases (hydrogen, nitrogen and oxygen) are present everywhere, including alloys, a series of experiments was carried out on treating melt of blast furnace iron with substances having great affinity with hydrogen. It is established: when treating melt with lead-base silumin in the low-temperature test interval, there is a slight increase in the linear expansion coefficient (LEC) at 100°C, compared with the initial one, to 8.210-6, deg-1. In the temperature range of 100-150°C LEC decreases to a minimum value of 7.210-6, deg-1. In the average temperature range of 150-300°C, a sharp, anomalous increase is noticeable, compared with the initial one up to 15.5210-6, deg-1. When studying the microstructure of cast iron after processing the melt with lead silumin, the formation of ledeburite structure is stated. Samples treated with lead-base silumin were subjected to cementation by feeding water steam at 900°C for 1-5 hours. It should be noted that, in the temperature range of 50-150°C, the values of the linear expansion coefficient lie almost in a straight line in the entire field of study. The coefficient varies from 10.810-6, deg-1 at 50°C to 13.710-6, deg-1 at 450°C. Preliminary heat treatment of cast iron in the carburizer made by the Bondyuzhsky plant with water steam smoothes anomalies of LEC and increases its initial values, and grinds perlite and cementite as well. Subsequent quenching in water with a temperature of 1000°C significantly changes the linear expansion coefficient of cast iron. Hardening of samples after cementation sharply reduces the linear expansion coefficient in the test range of 150-200°C, and in the temperature range of 350-450°C negative values of LEC are observed. Thus, it can be concluded, that treating the melt with lead-base silumin, cementation in the medium of the carburizer made by the Bondyuzhsky plant and subsequent hardening leads to sharp changes of the linear expansion coefficient up to negative values. The identified properties suggest the possibility of using cast iron where it is necessary to constancy of LEC and there are no requirements for the weight of the product.

Full textAbstract:
An extensive set of north- to northwest-trending diabase dykes, termed the Lac Esprit swarm, is identified in the Superior Province east of James Bay based on geological mapping and a distinctive paleomagnetic pole (61.7°N, 169.1°E, dm = 7.7°, dp = 5.5°). The Lac Esprit swarm yields a U–Pb baddeleyite age of 2069 ± 1 Ma similar to that of the 2076+5–4 Ma Fort Frances swarm of the western Superior Province. Their paleomagnetic declinations differ by 23° ± 12° after correction to a common reference locality. The difference is likely due mainly to counterclockwise rotation about a vertical axis of the Fort Frances area relative to the Lac Esprit area. Differential rotation of 10°–20° has been proposed more locally across the Kapuskasing Structural Zone separating the eastern and western Superior Province in earlier paleomagnetic studies of ca. 2450 Ma Matachewan and 2170 Ma Biscotasing dyke swarms. Thus, relative rotation may have involved the entire eastern and western Superior Province, perhaps in response to collisional events associated with the Trans-Hudson Orogen to the north or the Penokean orogen to the south, or in response to rifting beneath Hudson Bay. Other dykes in the study area are interpreted from a combination of paleomagnetism, trend, and geochemistry to belong to the Senneterre, Matachewan, and Mistassini swarms. The 2216 Ma Senneterre dykes form part of a giant swarm that fans across the eastern Superior Province. Paleomagnetic directions and geometry of this swarm rule out substantial block rotations within the eastern Superior Province since dyke emplacement.

Full textAbstract:
When Escherichia coli FC40 formed adaptive Lac+ revenants on a selective agar medium containing lactose as the carbon source, the colonies which accumulated over several days were of two readily distinguishable types. Colonies of both types appeared both early and late on the plates. Cells of colonies that appeared early and late on the plates, irrespective of the type, when grown in liquid medium and replated, all formed colonies on the selective medium within 48 h. Cells of each colony type gave rise to colonies of both types and attempts to isolate cells of each type in pure culture were unsuccessful. It was concluded that the presence of two colony types in the cultures plated did not contribute to the observed time dependency of colony formation during adaptive mutation. The proportions of the two colony types arising from cultures of the Lac+ revertants varied from culture to culture.Key words: Escherichia coli FC40, variants, adaptive mutation, colony accumulation.

Full textAbstract:
Discharge of by catch is a significant problem in world fishery. Every commercial fishery such as tuna longline has a suite of bycatch species, escolar fish (LEC). LEC as by catch product has received a little attention because of its lower economic value and given its importance as a secondary market. With time, however, market can become establish for this presently undesirable species. Acknowledging that today’s by catch might become tomorrow’s target fish. The aims of this study areto provide information on biological aspect and catch per unit of effort (CPUE) spatial distribution of escolar (Lepidocybium flavobrunneum) as by catch in Indonesian longline fishery operating in the Eastern Indian Ocean. Total escolar samples of 1,815 were taken from scientific observer data from 2011-2013. The study area of escolar was between 0.897-33.175°S and 85.366– 138.733°E of Eastern Indian Ocean. Results show that the escolar length (cmFL) is distributed from 27-178 cmFL (median=83 cmFL, mode=85 cmFL, mean=83.95 cmFL and n= 1.812) and dominated by the size of 85 cmFL. The length weight relationship was determined to be W=0.0002FL2.2926(W in kg, FL in cm). In terms of CPUEs distribution, the lower CPUEs(<1.0001) generally occurred near shore between Indonesia and Australia (10-20°S and 110 125°E).The highest CPUEs of escolar (>1.0001 to 7.382) generally occurred in Western Australian, precisely on grid between 10-35°S and 85-110°E. These grids would be a potential for fishing LEC with the best time to catch in June to August.

Full textAbstract:
ABSTRACT An approximately 200-kb plasmid has been purified from clinical isolates of Stenotrophomonas maltophilia. This plasmid was found in all of the 10 isolates examined and contains both the L1 and the L2 β-lactamase genes. The location of L1 andL2 on a plasmid makes it more likely that they could spread to other gram-negative bacteria, potentially causing clinical problems. Sequence analysis of the 10 L1 genes revealed three novel genes,L1c, L1d, and L1e, with 8, 12, and 20% divergence from the published strain IID 1275 L1(L1a), respectively. The most unusual L1 enzyme (L1e) displayed markedly different kinetic properties, with respect to hydrolysis of nitrocefin and imipenem, compared to those of L1a (250- and 100-fold lowerk cat/Km ratios respectively). L1c and L1d, in contrast, displayed levels of hydrolysis very similar to that of L1a. Several nonconservative amino acid differences with respect to L1a, L1b, L1c, and L1d were observed in the substrate binding-catalytic regions of L1e, and this could explain the kinetic differences. Three novel L2 genes (L2b, L2c, andL2d) were sequenced from the same isolates, and their sequences diverge from the published sequence of strain IID 1275L2 (L2a) by 4, 9, and 25%, respectively. Differences in L1 and L2 gene sequences were not accompanied by similar divergences in 16S rRNA gene sequences, for which differences of <1% were found. It is therefore apparent that the L1 and L2 genes have evolved relatively quickly, perhaps because of their presence on a plasmid.

Over the last decades, archivists believed the management of government records, without being perfect, was going smoothly and seamlessly: records from Canadian government institutions were acquired, processed and made accessible to Canadians in an organised, structured, and logical way. However, in his 2014 report, the Auditor General of Canada pointed out not only weaknesses but also failures in LAC activities related directly to its mandate: developing Records Disposition Authorities (RDA), processing archival material from departments and agencies, and making this heritage material available to Canadians or people interested in Canada. LAC was somehow shocked by this earthquake and had to cope with these problems and find solutions, within three years. My presentation has three parts: 1- the LAC Act, macro-appraisal and RDA; 2- the Auditor General’s report; 3- the creation of the LAC Task Force to deal with these archival issues. My conclusion will explore some elements about the management of digital archives for Canadian government institutions.

Full textAbstract:
A cross section of the resistivity structure through the Lac Bouchette gabbro–anorthosite provides a new image of the thin-skinned geometry of an allochthonous terrane in the western Grenville Province of Canada. Two-dimensional inversion of high-frequency magnetotelluric soundings and magnetic modelling indicate that the gabbro–anorthosite is a 1.5 km thick slice bounded by conductive thrust faults. Graphite, which is present at the margins of the gabbro–anorthosite and in the metasedimentary Réservoir Cabonga terrane to the south, is the most likely source of the enhanced electrical conductivity in the fault zones. The southern margin of the gabbro–anorthosite dips at about 15° to the south beneath the Réservoir Cabonga terrane. The gabbro–anorthosite can be divided into a highly magnetic gabbroic body in the south, a less magnetic metagabbro in the north, and a thin anorthositic lense in the centre. The combination of closely spaced magnetotelluric soundings and magnetic modelling provides independent constraints for gravity and seismic reflection studies in progress. The geometry of the Lac Bouchette gabbro–anorthosite, revealed by this geophysical study, supports a hypothesis that some gabbro–anorthosites behave as competent blocks adjacent to the major tectonic boundaries of the Grenville Province.
