Published: February 2024

AbstractDiastolic dysfunction is a major cardiac dysfunction, and an important predisposing factor is age. Although exercise training is often used for the prevention and treatment of cardiovascular disease nowadays, little is currently known about whether exercise interventions associated with the slowing of cardiac aging are related to mtp‐related pathways. In the present study, the UAS/Tub‐Gal4 system was used to knockdown whole‐body mtp expression levels in Drosophila, which underwent 2 weeks of endurance training. By conducting different assays and quantifying different indicators, we sought to investigate the relationship between mtp, exercise, and age‐related diastolic dysfunction. We found that (1) Drosophila in the mtpRNAi youth group exhibited age‐related diastolic dysfunction and had a significantly shorter mean lifespan. (2) Endurance exercise could improve diastolic dysfunction and prolong lifespan in aged Drosophila. (3) Endurance exercise could increase the expression levels of apolpp and Acox3, and decrease the levels of TC, LDL‐C, and TG in the aged group. In summary, aging causes age‐associated diastolic dysfunction in Drosophila, and systemic knockdown of mtp causes premature age‐associated diastolic dysfunction in young Drosophila. Besides, endurance exercise improves age‐related diastolic dysfunction and prolongs lifespan.

Abstract
Gold nanoparticles (Au-NPs) have several uses for nanobiotechnologists because of their beneficial biomedical properties. Alginates have various biomedical and industrial applications. The aim of this study is to extract alginate from Azotobacter chroococcum, synthesize chemical Au-NPs (Ch/Au-NPs), and load the NPs with the extracted alginate to form Azotobacter alginate gold nanocomposites (Azto/Alg-Au-NCMs). The Ch/Au-NPs and Azto/Alg-Au-NCMs were characterized by UV-spectroscopy, Fourier-transform infrared (FT-IR) spectroscopy, energy-dispersive spectroscopy (EDS), X-ray diffraction (XRD), thermogravimetric analysis (TGA), zeta potential, and transmission electron microscopy (TEM). The anticancer activities were determined using the breast cancer cell line MCF-7, human lung cancer cell line H1299, and Vero cell line. The results obtained by UV-spectroscopy exhibited a surface plasmon resonance that was clearly noticeable at 530 nm, and the EDS analysis proved that gold was present in percentages of 50.11 and 28.08 in the Ch/Au-NPs and Azto/Alg-Au-NCMs, respectively. There were several similarities between the alginic acid and the alginate extracted from A. chroococcum, and small modifications were proved by FT-IR spectroscopy. Negative charges were shown by the zeta potential. Crystalline and cubic NPs were shown by XRD analysis and TEM. TGA demonstrated the purity of the Ch/Au-NPs and the existence of organic compounds in the Azto/Alg-Au-NCMs. Both the Ch/Au-NPs and Azto/Alg-Au-NCMs had antibacterial activities against Staphylococcus aureus ATCC 25923, Proteus mirabilis, Enterobacter sp., and Pseudomonas aeruginosa and possessed anticancer activities against MCF-7 and H1299.

Abstract

Context
Walking groups run by trained individuals, lasting under an hour in a natural environment, may be a cost-effective way by which to encourage sustainable changes in physical activity as well as foster companionship and a shared experience of wellness among participants. Walk with a Doc (WWaD) is a national program that provides a platform for medical professionals, including physicians and medical students, to deliver a short talk on a health topic prior to walking side by side with patients and community members.

Objectives
To evaluate the WWaD Chapter at Stony Brook following implementation, a questionnaire was designed utilizing a mixed-methods approach (i.e., containing qualitative and quantitative items) and administered to all attendees monthly prior to the health discussion. The aim of the questionnaire was fourfold: first, to obtain participant demographics; second, to obtain information on attendees’ own perceptions of their health status and the role exercise plays in their health; third, to gain data on physical activity levels, including lengths of exercise sessions and types of activities performed; and fourth, to learn more about attendees’ motivations and goals for participating in the walks.

Methods
We received an IRB exemption. Physician and medical student volunteers were recruited from Stony Brook University Hospital, a suburban tertiary care center, to oversee program logistics. WWaD was scheduled to take place on the third Sunday of every month for 1 h at Heritage Park in Mount Sinai, New York. The event was advertised by volunteers to colleagues, peers, patients, and community members utilizing word of mouth, printed flyers, emails to listservs, and social media outlets. Each month, a physician volunteer oversaw a brief discussion (approximately 10 min in length).

Results
Over the course of the 5 month evaluation period, 91 individuals participated in the walks, including repeat attendees. After excluding duplicate or incomplete entries, data from 30 participants were included in this analysis. The majority of participants were female (n=24) with a mean age of 50 years (range, 23–98 years). Feedback on WWaD program elements was largely positive. Participants commended the monthly speakers for “informative talks” (n=6) on “interesting topics” (n=4), with plans to review the supplemental information in educational pamphlets following the walk (n=4). The brochures were also deemed “helpful.” Overwhelmingly, patients referred to the community gathering and team building aspects of WWaD as the “most enjoyable” aspect of the program (n=8) and a key driver for participation.

Conclusions
This mixed-methods study of the WWaD chapter at Stony Brook contributes to a growing body of evidence highlighting the value of walking groups as effective avenues for collaboration in producing accessible healthy behavior.
Enhanced inverse Faraday effect and time-dependent thermo-transmission in gold nanodisks

Published: February 2024

Abstract
Nonmagnetic media can be magnetized by light via processes referred to as an inverse Faraday effect (IFE). With nonmagnetic metal nanostructures, the IFE is dominated by the presence of light-induced solenoidal surface currents or plasmons with orbital angular momenta, whose properties depend on both the light and nanostructure geometry. Here, through a systematic study of gold nanodisks with different sizes, we demonstrate order-of-magnitude enhancement of the IFE compared to a bare gold film. Large IFE signals occur when light excites the dipolar plasmonic resonance of the gold nanodisk. We observe that the spectral response of the IFE signal mirrors the spectral response of time-dependent thermo-transmission signals. Our careful quantitative experimental measurements and analysis offer insight into the magnitude of IFE in plasmonic structures for compact, low-power, magneto-optic applications.

Este trabajo analiza las prácticas políticas de emigrantes españoles que, en el marco de diversas organizaciones, denuncian un ejercicio desigual del derecho al voto en el extranjero a partir de la aprobación de la Ley Orgánica 2/2011 que regula el Régimen Electoral General. La investigación forma parte de un amplio campo de estudios empíricos que analizan la relación entre política y derecho sobre la que se sostienen múltiples demandas y sobre la que se moldean subjetividades políticas. Desde una perspectiva histórico-etnográfica, el objetivo es demostrar cómo las prácticas políticas de estos emigrantes, basadas en el lenguaje contencioso de los derechos ciudadanos, conforman diferentes formas de comunidad organizada en búsqueda de vías de transformación de la mencionada ley. Y, al mismo tiempo, un reconocimiento como sujetos políticos dentro del campo político-nacional.

Quem são as pessoas presas em flagrante por tráfico de drogas no Recife durante a pandemia? As gratificações pagas aos policiais em razão do Programa Pacto pela Vida demonstram algum impacto nas prisões neste período? O estudo mapeia prisões em flagrante por tráfico de entorpecentes em Recife (Pernambuco) entre 17 de março de 2020 e 17 de março de 2021, apresentando dados quantitativos referentes ao perfil dos sujeitos presos e as condições de realização do flagrante. De um lado, dispensando maiores esforços teóricos em torno de uma já solidificada discussão criminológica acerca da seletividade que opera no sistema punitivo, evidencia-se continuidades, em que o jovem preto ou pardo, de baixa escolaridade e frequentador das áreas periféricas da cidade é o alvo preferencial da polícia militar; de outro, discute-se o incremento das práticas autoritárias apresentadas, analiticamente, em três blocos: a perversidade do sistema de justiça criminal para quem não teve o direito de lutar para viver, as ilegalidades relativas ao flagrante e a monetarização da violência policial. A partir da lente teórica da criminologia atuarial, somada ao cruzamento dos dados, compreende-se a política de segurança por uma perspectiva eficientista e identifica-se a potencialização de violações a direitos fundamentais, dado o cenário de emergência sanitária.

В статье приведены результаты полевых исследований сообществ, схожих по занимаемому экологическому пространству режимов солевого богатства почв (Tr) и увлажнения (Hd) с типом леса дубняк дубравномятликовый. Фоновыми видами древостоев являются Quercus robur L., Tilia cordata Mill., Betula pendula Roth., Populus tremula L., Acer platanoides L.; подлеска – Euonymus verrucosa Scop., Sorbus aucuparia L.; напочвенного покрова – Convallaria majalis L., Poa nemoralis L., Galium odoratum (L.) Scop. Эколого-ценотические спектры растений дубовых сообществ отличаются от остальных меньшей долей неморальных (Nm) видов, несколько большей – лугово-степных (сухо- (MDr) и влажно-луговых (MFr), а также степных (St)) видов. Дубовую часть древостоев можно считать устойчивой на основании критериев H/G, S2 и динамике таксационных характеристик, ценопопуляцию Q. robur L. вследствие одновозрастности деревьев и отсутствия постоянного оборота поколения – нестабильной и деградирующей.
The article presents the results of field studies of indigenous and derived communities, similar in terms of the ecological space occupied by the regimes of salt richness of soils (Tr) and moisture (Hd) with the type of forest oak forest, boromum. Background species of forest stands are Quercus robur L., Tilia cordata Mill., Betula pendula Roth., Populus tremula L., Acer platanoides L.; undergrowth – Euonymus verrucosa Scop., Sorbus aucuparia L.; ground cover – Convallaria majalis L., Poa nemoralis L., Galium odoratum (L.) Scop. The ecological-coenotic spectra of plants of indigenous communities differ from derivatives in a smaller proportion of nemoral (Nm) species, somewhat larger in meadow-steppe (dry (MDr) and wet-meadow (MFr), as well as steppe (St) species). The oak part of the forest stands can be considered stable based on the H/G, S2 criteria and the dynamics of taxation characteristics, while the cenopopulation of Q. robur L. due to the same age of the trees and the absence of a constant generation turnover is unstable and degrading.

Прогнозные расчеты использования и воспроизводства лесов, реализованные в виде различных, наиболее вероятных и перспективных сценариев, необходимы для стратегического планирования развития лесного сектора на региональном уровне. В данном исследовании получены научно обоснованные параметры объемов использования лесов на длительную перспективу, сопоставимую с оборотами рубки в хвойных хозяйственных секциях в лесах Архангельской области. В работе приведен анализ моделирования сценариев для лесов Архангельской области с использованием модели, разработанной учеными Северного НИИ лесного хозяйства (автор, доктор с.-х. наук Н.П. Чупров), классические варианты расчета лесосек, проводимых при выполнении лесоустройства. Результаты исследования показывают возможность поддержания стабильно высокого уровня объемов использования лесов по хвойным хозяйственным секциям с учетом смены пород и выполнения комплекса лесохозяйственных мероприятий. Для лесничеств юга Архангельской области прогнозируемый размер пользования лесом получается ниже официально принятых объемов, для лесничеств северной части наблюдается превышение расчетной лесосеки, для центральной части прогнозируемые объемы практически совпадают с расчетной лесосекой. Реализация интенсивной модели использования и воспроизводства лесов в регионе является одним из показателей вероятного применения одного из оптимальных сценариев многовариантного прогноза.
Forecast calculations of the use and reproduction of forests, implemented in the form of various, most probable and promising scenarios, are necessary for strategic planning of forestry sector development at the regional level. In this study, scientifically based parameters of forest use volume for the long term, comparable to the felling turnover in coniferous stands in the forests of the Arkhangelsk region, were obtained. The paper presents an analysis of scenarios modeling for the Arkhangelsk region forests using the model developed by scientists from the Northern Research Institute of Forestry (author N.P. Chuprov), classical options for calculating allowable cutting volumes carried out during performing forest inventory. The results of the study show the possibility of maintaining a consistently high level of forest use, taking into account the species change and the implementation of forestry measures complex. For the forest management units of the south part of the Arkhangelsk region, the predicted amount of forest use is lower than the officially accepted volumes, for the forestry’s of the northern part, there is an excess of the allowable cutting volume, for the central part it practically coincides. The implementation of an intensive model for the use and reproduction of forests in the region is one of the indicators of the likely application of one of the optimal multivariate forecast scenarios.

В статье рассмотрены вопросы продольной распиловки круглых лесоматериалов. Целью исследований являлась разработка ленточнопильного станка с упрощенной конструкцией, со сниженной металлоемкостью и увеличенной мобильностью. Реализована разработка нового технического решения в области конструкций ленточнопильных станков, непривязанных к конкретному одному цеху, а способных производить распиловку в разных местах, включая лесосеку. В статье дано подробное описание конструкции нового деревообрабатывающего станка и последовательность его работы при доставке на лесосеку для распиловки круглых лесоматериалов. Силовой агрегат через карданный вал автомашины, конический редуктор, ременную передачу и подшипниковый узел передает крутящий момент на ступенчатый шкив, образованный автомобильными резиновыми шинами двух разных диаметров, которые приводят в движение ленточную пилу. Предложенный вариант устройства ленточнопильного станка для продольной распиловки круглых лесоматериалов позволяет упростить конструкцию станка, уменьшить ее габариты и дает возможность производить продольную распиловку вдали от деревообрабатывающего предприятия, повышая мобильность технологического процесса. Получаемые необрезные пиломатериалы можно сразу транспортировать потребителю, что снижает себестоимость транспортировки сырья и хранения готовой продукции.
The article deals with the issues of longitudinal sawing of round timber. The aim of the research was to develop a band saw with a simplified design, with reduced metal consumption and increased mobility. The development of a new technical solution in the field of designs of band saws, not tied to a specific one workshop, but capable of sawing in different places, including cutting areas, was implemented. The article gives a detailed description of the design of the new woodworking machine and the sequence of its work when delivered to the logging site for sawing round timber. The power unit transmits torque through the driveshaft of the vehicle, the tapered gearbox, the belt gear and the bearing assembly to the stepped pulley formed by the automobile rubber tires of two different diameters that drive the band saw. The proposed design of the device of the band saw for longitudinal sawing of round timber allows to simplify the design of the machine, reduce its dimensions and makes it possible to produce longitudinal sawing away from the woodworking enterprise, increasing the mobility of the technological process. The resulting unedged lumber can be immediately transported to the consumer, which reduces the cost of production transportation of raw materials and storage of finished products.

Показана возможность модификации минерального наполнителя- карбоната кальция ноноволоконной целлюлозой. В качестве нановолоконной целлюлозы применена бактериальная целлюлоза, синтезированная штаммом бактерий Komagataeibacter rhaeticus CALU-1629 в количестве 1–5% к массе а.с. волокна. Установлено, что модификация наполнителя бактериальной целлюлозой позволяет получить бумагу с содержанием наполнителя до 50%, обеспечивая его удержание в бумаге на 95–98% без применения удерживающих веществ. Модификация наполнителя бактериальной целлюлозой позволяет повысить механическую прочность бумаги с наполнителем и снизить впитывающую способность бумаги, что даст возможность значительно сократить использование катионного крахмала и проклеивающих веществ в производстве бумаги.
The possibility of modification of mineral filler-calcium carbonate by nonofiber cellulose is shown. Bacterial cellulose synthesized by bacterial strain Komagataeibacter rhaeticus CALU-1629 in the amount of 1–5% to the mass of a.s. fiber was used as nanofiber cellulose. It is established that modification of the filler with bacterial cellulose allows to obtain paper with the content of filler up to 50% providing its retention in the paper by 95–98% without the use of retaining agents. Modification of the filler with bacterial cellulose allows to increase the mechanical strength of paper with filler and reduce the absorbency of paper, which will make it possible to significantly reduce the use of cationic starch and bonding agents in paper production.
