Abstract
It has been studied that both two-dimensional (2D) MoS2 and V2O5, which are classified as transition metal dichalcogenides and transition metal oxides, are good photocatalyst materials. For this purpose, the hydrothermal method was practiced to synthesize V2O5(1−x)MoS2(x) (X = 1–5% w/w) nanocomposites with different 1–5% w/w weight percent of MoS2 as a prominent photocatalyst under laser irradiation for 2, 4, 6, 8, and 10 min to tune photocatalytic degradation of industrial wastage water. The surface of the 2D molybdenum nanolayered matrix was efficaciously decorated with V2O5 nanoparticles. The crystal phase and layered structures of the V2O5(1−x)MoS2(x) (X = 1–5% w/w) nanocomposites samples were verified by X-ray diffraction and scanning electron microscopy, atomic force microscopy, X-ray photoelectron spectroscopy respectively. In the range of the UV visible spectrum, the increment in light absorption from 3.6 to 14.5 Ω−1 cm−1 with an increase of active surface from 108 to 169

with increased MoS2 doping percentage. Furthermore, dielectric findings like the complex dielectric function, tangent loss, electrical conductivity, quality factors, and impedance of V2O5(1−x)MoS2(x) (X = 1–5% w/w) nanocomposites are studied. According to photoluminescence studies, the intensity of peaks decreases when laser irradiation time and doping percentages of MoS2 are increased. As a result, a small peak indicates a decrement rate of electron–hole pair recombination, which increases the capacity for separation. Thermo-gravimetric analysis and differential thermal analysis results revealed that weight loss decreased from 0.69 to 0.35 mg and thermal stability increased with increased doping concentrations. Methylene blue was degraded in 150 min, proving that the prepared MoS2-doped V2O5 material was a stable and economically low-cost nanocomposite for photocatalytic activity.

Published: August 2024

Abstract
Cancer is a major cause of death worldwide and a serious threat to human health. Cisplatin, a widely used first-line chemotherapeutic agent for various solid tumors, is renowned for its efficacy but is limited by significant cytotoxicity. Cisplatin triggers pyroptosis in tumor cells by activating Gasdermin proteins, thereby enhancing its anticancer efficacy. However, this same mechanism can induce pyroptosis in normal cells, causing inflammation and toxicity in healthy tissues, such as nephrotoxicity and ototoxicity. The objective of this review is to identify the major molecular targets for optimizing the cisplatin treatment window by summarizing recent advances in the pyroptosis caused by cisplatin in different cancer types and normal tissues. Among them, gasdermin D and gasdermin E are the main molecular targets involved in cisplatin-induced pyroptosis, and GSDMB also has similar effects. Future research directions include exploring targeted drug delivery systems and target regulating GSDMs (gasdermin protein family) to selectively modulate pyroptosis, thereby maximizing cisplatin’s anticancer effects while minimizing its side effects. Therefore, this review provides a comprehensive overview of cisplatin-induced pyroptosis, offering new insights into therapeutic strategies in cancer treatment.

Published: August 2024

Abstract
Melt-quenching was used to create high density glasses with a chemical composition of (15-x) Na2O–45B2O3–20Bi2O3–20SiO2–xLa2O3, where, x = (0 ≤ x ≥ 15) mol%. Through the use of (XRD) analysis, the amorphous status of these glasses was ascertained. We examined on the synthetic glasses physical attributes as well as their ability to shield against gamma radiation. The density increased from 4.913 g/cm3 for BBSNLa0 glass to 6.497 g/cm3 for BBSNLa15 glass. The study employed the Phy-X/PSD code to explore the radiation shielding properties of these glasses. As the mol% of La2O3 increases, the MFP decreases. This indicates that glass samples with a higher concentration of La2O3 have a greater ability to attenuate or absorb photons, resulting in a shorter average distance traveled before interaction. The BBSNLa-15 glass sample is the best choice for applications in radiation protection.
Comprehensive review of metal-based coordination compounds in cancer therapy: from design to biochemical reactivity
Authors: Omer Peshang Khdir , Aziz Nazk M. , Omer Rebaz Anwar 
Published: August 2024

Abstract
Throughout history, metal-based coordination compounds have been used for medical purposes, including the treatment of various illnesses like cancer. Since the discovery of cisplatin in 1965, many other metal coordinating complexes have been developed and evaluated, involving metals such as platinum, iron, zinc, ruthenium, gold, silver, titanium, and copper. The goal behind these efforts is to create effective and safe medications. At the moment, there are a lot of studies talking about the use of cytostatic metal complexes, mainly on promising platinum- and non-platinum-based drugs in both preclinical and clinical trials. However, there is a lack of recent comprehensive studies that cover both the chemical and biological aspects of metal-based coordinating molecules in the context of cancer therapy. This review aims to provide a thorough analysis of the coordination chemistry of existing and innovative cytostatic substances. It will include a description of their design and synthesis, as well as a summary of the biochemical reactivity and physicochemical features of potential metal-containing complexes.

Abstract
Thyroid hormones (THs) are essential in neuronal and glial cell development and differentiation, synaptogenesis, and myelin sheath formation. In addition to nuclear receptors, TH acts through αvβ3-integrin on the plasma membrane, influencing transcriptional regulation of signaling proteins that, in turn, affect adhesion and survival of nerve cells in various neurologic disorders. TH exhibits protective properties during brain hypoxia; however, precise intracellular mechanisms responsible for the preventive effects of TH remain unclear. In this study, we investigated the impact of TH on integrin αvβ3-dependent downstream systems in normoxic and hypoxic conditions of pheochromocytoma PC12 cells. Our findings reveal that triiodothyronine (T3), acting through αvβ3-integrin, induces activation of the JAK2/STAT5 pathway and suppression of the SHP2 in hypoxic PC12 cells. This activation correlates with the downregulation of the expression palmitoyltransferase-ZDHHC2 and ZDHHC9 genes, leading to a subsequent decrease in palmitoylation and phosphorylation of Fyn tyrosine kinase. We propose that these changes may occur due to STAT5-dependent epigenetic silencing of the palmitoyltransferase gene, which in turn reduces palmitoylation/phosphorylation of Fyn with a subsequent increase in the survival of cells. In summary, our study provides the first evidence demonstrating the involvement of integrin-dependent JAK/STAT pathway, SHP2 suppression, and altered post-translational modification of Fyn in protective effects of T3 during hypoxia.

Рассмотрены методы и системы формирования гиперспектральных данных на базе спектрального сканирования и без сканирования изображений. Это обусловлено переходом во многих практических задачах от аэрокосмических к «наземным» методам гиперспектральной съёмки. Представлены варианты реализации спектроразделительных устройств - ключевого элемента современных смотрящих гиперспектрометров. Приведены основные параметры и технические характеристики абсорбционных, интерференционных и жидкокристаллических фильтров, показаны их принципиальные возможности. Сечение фильтруемого светового пучка и его угловая апертура в таких устройствах могут быть весьма велики, что делает их пригодными для исследования объектов слабых излучений. Рассмотрены перестраиваемые фильтры без механических перемещений элементов конструкции на базе быстродействующих акустооптических устройств и планарных интерферометров Маха - Цендера с электростатическим управлением. В настоящее время их предельное спектральное разрешение составляет величину менее 1 нм для видимого и ближнего инфракрасного диапазонов.
Methods and systems for generating hyperspectral data based on spectral scanning and without image scanning are considered. This is due to the transition in many practical problems from aerospace to “ground-based” hyperspectral imaging methods. Options for implementing spectrum separation devices, a key element of modern viewing hyperspectrometers, are presented. The main parameters and technical characteristics of absorption, interference, and liquid crystal filters are presented, and their fundamental capabilities are shown. The cross section of the filtered light beam and its angular aperture in such devices can be very large, which makes them suitable for studying objects of weak radiation. Tunable filters without mechanical movements of structural elements based on high-speed acousto-optical devices and planar Mach-Zehnder interferometers with electrostatic control are considered. Currently, their maximum spectral resolution is less than 1 nm for the visible and near-infrared ranges.

Published: August 2024

Исследуются методы выбора коэффициента размытости ядерных функций регрессионной оценки плотности вероятности одномерной случайной величины. Регрессионная оценка плотности вероятности является модификацией статистики Розенблатта - Парзена и используется при обработке статистических данных большого объёма. Её синтез основан на сжатии исходной выборки путём декомпозиции области значений случайной величины. Элементами полученного массива данных являются центры интервалов дискретизации и частоты принадлежности им значений случайной величины из исходной выборки. Эта информация является достаточной для оценивания плотности вероятности случайной величины в виде непараметрической регрессии. Поэтому появляется возможность выбора коэффициента размытости ядерных функций регрессионной оценки из условия минимума её ошибки аппроксимации искомой плотности вероятности. Традиционный подход оптимизации непараметрической оценки плотности вероятности основан на минимизации её среднего квадратического отклонения. Анализируются аппроксимационные свойства регрессионной оценки плотности вероятности при использовании рассматриваемых методов её оптимизации.
The methods of bandwidth selection of the kernel functions of the regression estimation of the probability density of a one-dimensional random variable are investigated. Regression estimation of the probability density is a modification of the Rosenblatt-Parzen statistics and is used in processing of large-volume statistical data. Its synthesis is based on compression of the initial sample by means of decomposition of the range of values of the random variable. The elements of the resulting data array are the centers of the sampling intervals and the frequency of belonging of the values of the random variable chosen from the initial sample to them. This information is sufficient to estimate the probability density of the random variable in the form of a nonparametric regression. Therefore, it becomes possible to select the bandwidths of the kernel functions of the regression estimate from the condition of the minimum error of the desired probability density approximation. The traditional approach to optimizing nonparametric estimation of the probability density is based on minimizing its mean square deviation. The approximation properties of regression estimation of the probability density are analyzed when using the considered methods of its optimization.

Published: August 2024

BACKGROUND AND OBJECTIVESHigh-flow nasal cannula (HFNC) is used in up to 50% of children admitted with bronchiolitis. Consensus recommendations for feeding these children have not been established, and there is variability in practice. We sought to identify factors influencing feeding decisions for general care patients admitted with bronchiolitis on HFNC from a national sample of interdisciplinary care team members.METHODSIn this qualitative study, we conducted semi-structured virtual interviews with care team members involved in making feeding decisions at 10 US hospitals from June 2022 to March 2023. Eligible participants included 1 nurse, respiratory therapist, speech language pathologist, and physician from each site. Interviews were audio-recorded, transcribed, and conducted until reaching sufficiency. Three researchers analyzed transcript data using content analysis guided by the Systems Engineering Initiative for Patient Safety 2.0 model.RESULTSWe interviewed 29 participants, including 19 nurses, respiratory therapists, and speech language pathologists and 10 physicians. Participants identified 11 factors influencing feeding decisions related to hospital work systems and processes outlined in the Systems Engineering Initiative for Patient Safety model, including people (child and parent characteristics, care team experience), tools and technology (guideline, protocol, ordersets), organization (institutional culture, education), environment (time of day, care location), task (interventions to optimize feeding), and process (clinical assessment, feeding trial, communication).CONCLUSIONSOur findings suggest that feeding decisions are driven by factors related to the child, care team experience, institutional tools, and culture. These key factors may inform local improvement efforts to decrease variation in feeding children with bronchiolitis requiring HFNC.

El papel del biocarbono en la sostenibilidad y competitividad de sistemas agropecuarios
Authors: Preston Thomas R 
Published: August 2024

Resumen Un gran desafío para los planificadores agrícolas es en el diseño de sistemas agrícolas que combinan la producción de alimentos y la energía con una huella de carbono negativa. El biocarbono promete ser un elemento importante de esta estrategia. El biocarbono es el producto de la carbonización de la biomasa fibrosa en un flujo restringido de aire y a altas temperaturas (de 500 a 1000 °C). Es una mezcla de carbono y ceniza, No contiene nutrientes pero puede aumentar la fertilidad del suelo, incrementando la capacidad de retención de agua y de los nutrientes. Actúa como sitio que facilita la adsorción de nutrientes y micro-organismos del suelo, facilitando la actividad microbiana. Tiene el potencial de ayudar a mitigar el cambio climático, a través de la captura de carbono. Las condiciones de alta temperatura y aire restringido que favorecen la producción de biocarbono se encuentran en que los gasificadores sean estufas ascendentes (TLUD) o reactores de corriente descendente produciendo gas para motores y turbinas o simplemente calor de proceso (como en la fabricación de ladrillos). Así, desde el principio, mediante el uso de residuos fibrosos como materia prima, el sistema de gasificación y la producción asociada de biocarbono, evita el conflicto que se presenta cuando se producen biocombustibles a partir de los recursos naturales de los suelos y el agua en lugar de usar estos recursos como fuente de alimentos (Caja 1). Biocarbono es por tanto un subproducto del proceso de producción de energía a partir de biomasa no comestible.
