Lifetime Estimate of Various Polymeric Hybrid Blend Composites Corroborated with their Mechanical Testing, FTIR and Colour Spectroscopy
Authors: Praharaj Bhatnagar Manoj
Published: August 2022

This paper discusses the performance of 3 compositions; selected from the pool of certain hybrid blends of Polyamide 12 : HDPE, Hytrel : Polytrimethylene Terephthalate (PTT), and Wollastonite reinforced Hytrel : HDPE. These compositions display high Shore D & Scratch hardness, and have been compared to the most popular choice for electrical cable jacketing i.e. High Density Polyethylene (HDPE). High hardness blends of Hytrel : PTT (60:40), Polyamide 12 : HDPE (20:80+5% MA-g-PE), and 4% GPTMS treated 15 wt. % Wollastonite composite in Hytrel : HDPE (60:40+5% PE-BA-GMA); have been tested for important weathering performance properties, required for wires and cables. These compositions have been subjected to QUV accelerated weathering, Soil burial testing, and High temperature ageing, to elucidate weathering properties. Further, these samples have been tested for their various mechanical properties, like tensile strength and roughness after exposure. Changes in chemical structure as a result of the weathering studies have been studied using ATR – FTIR, and changes in colour of the specimens have been noted using colour spectrophotometry. It is seen that PA 12 based samples show best resistance to UV degradation, soil burial weathering, and high temperature oxidation. Using Arrhenius equation, and including all three modes of degradation carried out at different temperatures, the time taken for the samples to reach 50% of their initial tensile strength have been determined.
Metal-Catalyzed Hydrophosphination
Authors: Novas Bryan , Waterman Rory
Published: August 2022

Organophosphines have garnered attention from many avenues ranging from agriculture to fine chemicals. One-time use of phosphate resources has made sustainable use of phosphorus overall imperative. Hydrophosphination serves as an efficient method to selectively prepare P–C bonds, furnishing a range of phosphorus-containing molecules while maximizing the efficient use of phosphorus. Since its discovery in the 1990s, a wide array of catalysts have appeared for hydrophosphination, a reaction that is spontaneous in some instances. This review presents a representative view of the literature based on known catalysts through mid-2022, highlighting extensions to unique substrates and advances in selectivity. While several excellent reviews have appeared for aspects of this transformation, this review is meant as a comprehensive guide to reported catalysts.

Published: August 2022

Antimicrobial resistance is one of the major human health threats with significant impact on the global economy. Antibiotics are becoming increasingly ineffective as drug-resistance spreads, imposing an urgent need for new and innovative antimicrobial agents. Metal complexes are an untapped source of antimicrobial potential. Rhenium complexes, amongst others, are particularly attractive due to their low in vivo toxicity and high antimicrobial activity, but little is known about their targets and mechanism of action. In this study, a series of rhenium di- and tricarbonyl diimine complexes was prepared and evaluated for their antimicrobial potential against 8 dif-ferent microorganisms comprising Gram-negative and -positive bacteria. Our data showed that none of the Re dicarbonyl or neutral tricarbonyl species have either bactericidal or bacteriostatic potential. In order to identify possible targets of the molecules, and thus possibly understand the observed differences in the antimicrobial efficacy of the molecules, we computationally evaluated the binding affinity of active and inactive complexes against structurally characterized membrane bound S. aureus proteins. The computational analysis indicates two possible major targets for this class of compounds, namely lipoteichoic acids flippase (LtaA) and lipoprotein signal peptidase II (LspA). Our results, consistent with published in vitro studies, will be useful for future design of rhenium tricarbonyl diimine-based antibiotics.

Authors: Borodulin Vladimir I. , Banzelyuk Egor N. , Topolyanskiy Aleksey V.
Published: August 2022

Russian nephrology, like most clinical disciplines, has passed through two stages in its historical development: at the first stage, it became isolated as an important area of scientific research within the framework of the Soviet clinic of internal diseases, at the second stage it became an independent scientific and educational clinical discipline and medical specialty. The article shows the role of Kazan internist S.S. Zimnitsky as one of the founders of nephrology in the USSR at the first stage of its formation and as one of the leaders of the functional direction in Soviet clinical medicine.

Authors: Grechukhina Katerina S. , Chebotareva Natalia V. , Zhukova Liudmila G. , Androsova Tatiana V. , Karpov Vladimir V. , Krasnova Tatiana N.
Published: August 2022

Background. Antiangiogenic drugs are widely used in oncological practice and are aimed at inhibiting angiogenesis. Despite the high antitumor efficacy, their use may be limited by nephrotoxicity, and therefore the search for early biomarkers of kidney damage remains relevant, which will preserve a favorable safety profile of therapy.
Aim. To determine urinary biomarkers of tubular and podocyte damage in patients receiving treatment with antiangiogenic drugs.
Materials and methods. The study included patients (n=50) who received intravenous anti-VEGF drugs (aflibercept, bevacizumab, ramucirumab) in various chemotherapy regimens. Concentrations of tubular damage markers KIM-1 (Kidney Injury Molecule-1) and NGAL (Neutrophil Gelatinase-Associated Lipocalin), hypoxia marker HIF-1 (Hypoxia-Inducible Factor 1-alpha) in urine samples were determined by enzyme-linked immunosorbent assay (ELISA) before treatment, and during 8 weeks of treatment. To assess the risk factors for kidney damage, a logistic regression analysis was performed with the inclusion of the main clinical and laboratory parameters.
Results. A decrease in the calculated GFR of CKD-EPI (Chronic Kidney Disease Epidemiology Collaboration Formula) of less than 60 ml/min per 1.73 m2 at week 8 of treatment was noted in 42% of patients. An increase in NGAL, KIM-1, HIF-1 and nephrin in urine during the first two weeks of therapy predicted the development of renal damage by the 8th week of follow-up. When constructing ROC-curves, the high sensitivity and specificity of these urinary indicators as prognostic markers were established. Among the clinical and laboratory indicators, independent unfavorable prognostic factors of nephrotoxicity were an initial decrease in eGFR, a history of hypertension, an increase in the concentration of KIM-1 and HIF-1 in urine during the first two weeks of therapy.
Conclusion. The predictors of renal damage in the treatment with antiangiogenic drugs were previously an increase in NGAL, KIM-1 and HIF-1 in urine during the first two weeks after the start of therapy.
Modern view on the complement system role in membranous nephropathy
Authors: Kamyshova Elena S. , Semeryuk Tatyana A. , Bobkova Irina N.
Published: August 2022

Membranous nephropathy (MN), an immune-mediated glomerular disease, is the most common cause of adult nephrotic syndrome. In MN, proteinuria is developed by podocyte damage due to the complement system activation in response to the subepithelial deposition of immune complexes containing various auto- and exogenous antigens. Membrane-attacking complex (MAC) is the terminal product of any complement pathways activation (classical, lectin or alternative) and plays the leading role in the complement-mediated podocytic damage. Thus far, the main pathway of complement activation leading to the formation of MAC in MN has not been established. The review highlights current evidence of various complement pathways activation in the development of MN, as well as recently established new molecular mechanisms of complement-mediated podocyte damage.

Published: August 2022

Aim. To evaluate the efficacy and safety of Brainmax in comparison with ethylmethylhydroxypyridine succinate and trimethylhydrazinium propionate in patients with ischemic stroke in the acute and early recovery period.
Materials and methods. An open multicenter randomized study included 180 patients aged 1880 years (mean age 60.917.66 years, men 47.8%) with ischemic stroke in the acute and early recovery period (NIHSS from 3 to 15 points). Patients were randomized to receive Brainmax, ethylmethylhydroxypyridine succinate and trimethylhydrazinium propionate in an equal ratio (n=60). The drugs were administered intravenously for 10 days, followed by a transition to intramuscular injection for 14 days. Efficacy was assessed using the following scales: Modified Rankin Scale, NIHSS, Rivermead Mobility Index, Montreal Cognitive Assessment Scale (MoCA). Safety assessment was carried out according to the presence and structure of adverse events.
Results. The mean Modified Rankin Scale score for Visits 3 (day 10) and 5 (day 25) for the group treated with Brainmax was 2.410.85 and 1.440.91 points, for the group EMHPS 2.870.68 and 2.180.85 points, and for the group receiving trimethylhydrazinium propionate 2.870.50 and 2.550.70 points respectively, which reflects the best functional outcome in the Brainmax group (p0.05). Comparison of cognitive function indicators also showed statistically significant differences between the groups of drugs Brainmax and ethylmethylhydroxypyridine succinate. Evaluation according to the MoCA test showed that the use of Brainmax is 20% more effective in restoring cognitive functions (compared to monodrugs).
Conclusion. The present study confirms the superiority of combination therapy with Brainmax over monotherapy with each of the components.

Published: August 2022

La disminución de las reservas de combustibles fósiles, así como la contaminación y el efecto invernadero (causante del cambio climático) que estas producen, han promovido el aumento del uso de energías renovables. En este ámbito, el Perú empezó a aprovechar estas energías, pero de este grupo, la que menos mención, investigación y proyectos tiene es la energía geotérmica, aun cuando se tiene una gran fuente de esta energía, sobre todo en la zona sur de nuestro país. Este proyecto nace ante el poco aprovechamiento que se da a esta energía y como una propuesta se presenta el estudio de la posibilidad de utilizar una bomba de calor geotérmica, así como el cálculo de cargas térmicas y dimensionamiento de ésta, para la producción de ACS, calefacción y refrigeración por suelo radiante/refrescante instalada en una vivienda unifamiliar que se encuentra en el distrito de Calacoa, provincia de Sánchez Cerro, departamento de Moquegua. La instalación de geotermia se dimensiona a partir de las cargas térmicas calculadas (5.07 KW en verano y 4.66 KW en invierno). Estas son halladas a partir de las características de la vivienda, condiciones exteriores e interiores, actividad realizada en el local, habitantes, etc. El presente trabajo incluye un estudio económico que compara los costos que implica la instalación geotérmica con los de otros sistemas convencionales. Además, se analiza el tiempo requerido para amortizar dicha instalación. Por otro lado, se realiza un estudio ambiental fundamentado en la comparación de las emisiones de CO2 que produce cada sistema, los cuales nos da como resultado una mayor emisión en los casos de Gas natural y BC aerotérmica de 5.54 tCO2/kWh y 3.8329 tCO2/kWh respectivamente, comparado con la BC geotérmica el cual nos da 2.0207 tCO2/kWh.

Survey of bioinformatics courses and concentrations in ALA-accredited master’s programs
Authors: Graham Leah , Moleirinho Melissa
Published: August 2022

Introduction: The interdisciplinary field of Bioinformatics is considered an information-based discipline by many. Yet, it is unclear how MLIS degrees prepare librarians to apply their expertise in this unique, often non-textual information environment. The goal of this study is to identify the availability of LIS-based bioinformatics educational opportunities to provide an update to the current bioinformatics landscape in North American LIS/iSchools.

Methods: We conducted a survey of available bioinformatics courses and program concentrations within 69 ALA-accredited master’s programs. Using course catalogues and program descriptions on department websites, we identified the existence of courses and concentrations specific or related to the field of bioinformatics. We also surveyed the availability of associated certificate programs or degree alternatives.

Results: Only two LIS-based bioinformatics courses are currently offered to MLIS students in ALA-accredited programs. There are no bioinformatics concentrations offered in the programs surveyed, however two graduate certificates could be applied towards an ALA-accredited master’s degree. Students interested in related fields can pursue degree alternatives, including 8 dual degree options.

Discussion: The scarcity of LIS-based bioinformatics courses and program concentrations may suggest that LIS has not adopted bioinformatics into their field nor curricula. As a result, students interested in pursuing careers in bioinformatics and related disciplines must actively seek out opportunities for education and professional development. Bioinformatics degree options within LIS/iSchools points towards an increased dialogue and acceptance of the connection between bioinformatics and information science, but the lack of ALA-accreditation limits possibilities for emerging librarians.

Published: August 2022

The influence of the age of the scion and the insulating material on the survival rate and morphometric para- meters of annual grafted plants is shown, using the example of Larix kaempferi ‘Blue Dwarf’. It has been established that when grafting decorative forms of the genus Larix Mill. the most effective is the use of annual shoots as a scion with isolation of the grafting site with an elastic polyethylene film, which ensures 100 % survival and optimal development of the crown.

The use of 2-year-old shoots as a scion with a shortened by 2/3 annual growth does not lead to a significant change in sur- vival rate and a decrease in the height and diameter of annual grafted plants, but it allows to increase the density of the crown. The use of these shoots as a graft can be recommended for propagation of garden forms, the grafting of which is complicated due to thin annual shoots.

Published: August 2022

Una mayor diversidad de forrajes en otoño-invierno incrementa la entrada de carbono (C) y nitrógeno (N) al suelo en los residuos de cosecha. El objetivo del estudio fue evaluar el aporte potencial de C y N al suelo en los residuos de forrajes alternativos y tradicionales durante el ciclo otoño-invierno. En el experimento se evaluó el rendimiento de materia seca (MS), cantidad de residuos y la relación C/N en 11 especies forrajeras. Los cultivos tradicionales avena, cebada, triticale, trigo, trébol Alejandrino y ballico anual aportaron menor cantidad de residuos de cosecha (365 a 612 kg ha-1) y de menor calidad con valores de la relación C/N de 23.5 a 42.8. Los cultivos alternativos canola, remolacha, brásicas, rábano y garbanzo aportaron mayor cantidad de residuos (432 a 2 958 kg ha-1), con mayores contenidos de N (18.5 a 32.6 g kg-1) y menores valores de la relación C/N (11.4 a 20). Los cultivos alternativos con raíces engrosadas como remolacha, brásicas y rábano mejoraron la cantidad y calidad de aportación de residuos de cosecha, con una capacidad potencial de captura de C similar a los cultivos tradicionales. Sin embargo, sólo la brásica Winfred y el rábano Graza obtuvieron rendimientos de MS (10 094 a 11 636 kg ha-1) similares o mayores a los observados en los cereales testigo avena Cuauhtémoc (11 161 kg ha-1) y triticale AN105 (9 644 kg ha-1). Una mayor diversidad de forrajes puede mejorar en cantidad y calidad la aportación de residuos de cosecha al suelo.

La representación del claustro docente en el gobierno universitario ¿Existe la alternancia?
Authors: Rissi Matilde , Guillermo Oloriz Mario
Published: August 2022

El ejercicio de la representación de un determinado sector en los órganos de gobierno ha motivado numerosos estudios respecto de la legitimación de la voluntad del elector por parte del representante, así como el respeto a la voluntad delegada en esos representantes. En el caso particular de las Universidades Nacionales de la República Argentina, el cogobierno universitario y el ingreso irrestricto son dos de los principios de la autonomía universitaria que se defienden y sostienen con mayor fuerza en los pronunciamientos de todos los claustros que integran dicho cogobierno. Sin embargo, este sistema altamente democrático, si bien es de carácter meritocrático dado que el peso de la representación no se da de manera igualitaria por claustro por la premisa que el mayor peso en la toma de decisiones debe recaer en los que se encontrarían más preparados para ello, la manera en que se ejerce la representación de los claustros y la renovación de quienes la ejercen podría deteriorar o alterar la finalidad que persigue quien ocupa ese lugar en representación de los intereses de un sector de la comunidad universitaria. En este trabajo, se analiza, en particular, la representación del claustro docente en el consejo superior de una muestra de seis universidades nacionales argentinas, entre los años 2011 y 2017, indagando respecto de cómo se da dicha representación y se mantiene entre los distintos procesos electorales. Se concluye que se observa una tendencia a una mayor repetición de quienes ejercen la representación en las universidades de mayor tamaño o en algunas de las regiones territoriales con las que se conforma el Sistema de Universitario Nacional. Al mismo tiempo, se encontró un fuerte predominio masculino tanto en la representación con carácter de titular en el consejo superior como en la tasa de repetición en la función.

Published: August 2022

In worldwide, the use of chemical pesticides to protect wood has been greatly restricted. In recent years, a large number of researchers devoted to the search for natural, safe and non-polluting bioactive chemical compounds from plants as an alternative to synthetic organic chemical preservative. In Chinese folk, tung oil can be used as paint for wooden furniture to protect them from pests. This study aimed to evaluate the chemical compositions of raw and heated tung oil and their activity against termite. In choice bioassays, weight loss of wood treated with 5% raw or heated tung oil after 4 weeks was significantly less than that of the control group. In no-choice bioassays, there was a significant difference in termite survival and wood weight loss on raw and heated tung oil-treated wood. When tung oil-treatment concentrations increased to 5%, wood weight loss was less than 10%. There was no significant difference in termite survival and wood weight loss between raw and heated tung oil-treated wood. Survival of termites in both tung oil wood treatments was significantly lower than that in the starvation control after 4 weeks. Raw and heated tung oil significantly improved the resistance of pine wood to termites, and have the potential for the development of natural wood preservatives.
