Senolytics, which eliminate senescent cells from tissues, represent an emerging therapeutic strategy for various age-related diseases. Most senolytics target antiapoptotic proteins, are overexpressed in cells, limiting specificity and inducing severe side effects. To overcome these limitations, we constructed self-assembling targeting with intracellular oligomerization system. Intracellular aryl-dithiol-containing peptide occurred only inside the mitochondria of due to selective localization...
Abstract Background In this priority-setting exercise, we sought to identify leading research priorities needed for strengthening future pandemic preparedness and response across countries. Methods The International Society of Global Health (ISoGH) used the Child Nutrition Research Initiative (CHNRI) method preparedness. Eighty experts in global health, translational clinical identified 163 ideas, which 42 then scored based on five pre-defined criteria. We calculated intermediate...
Summary Acinetobacter oleivorans DR 1 can utilize C 12 –C 30 alkanes as a sole carbon source but not short‐chain (C 6 , 10 ). Two copies of each alkB ‐, almA ‐ and ladA ‐type alkane hydroxylase ( AH ) are present in the genome cells. Expression mutational analyses s showed that alkB1 alkB2 major ‐encoding genes under roles other negligible. Our data suggested AlkB1 is responsible for long‐chain utilization 24 26 ), AlkB2 important medium‐chain 16 metabolism. Phylogenetic revealed large...
Abstract This paper reports the synthetic route of 3-D network shape α-Fe 2 O 3 from aqueous solutions iron precursor using a non-ionic polymeric soft-template, Pluronic P123. During synthesis , particle sizes, crystal phases and morphologies were significantly influenced by pH, concentrations template. The unique worm-like hematite was obtained only when starting solution prepared weakly basic pH condition very specific composition constituents. synthesized nanocrystal at this had narrow...
Bacterial alkane metabolism is associated with a number of cellular stresses, including membrane stress and oxidative stress, the limited uptake charged ions such as sulfate. In present study, genes ssuD tauD in Acinetobacter oleivorans DR1 cells, which encode an alkanesulfonate monooxygenase taurine dioxygenase, respectively, were found to be responsible for hexadecanesulfonate (C16SO3H) metabolism, Cbl was experimentally identified potential regulator expression. The expression occurred...
This study presents the filter design of GNSS/IMU integration for wearable EPTS (Electronic Performance and Tracking System) football players. has been widely used in sports fields recently, GNSS (Global Navigation Satellite IMU (Inertial Measurement Unit) have to measure provide players’ athletic performance data. A sensor fusion technique can be high-quality analysis data performance. For this reason, is designed study. The loosely-coupled strategy considered integrate considering...
Introduction The COVID-19 pandemic has negatively impacted college students’ mental health and wellbeing. Even before the pandemic, young adults reported high morbidity. During adult students faced unprecedented challenges, including campus closure a pivot to fully online education. Methods This study employed novel participatory approach Course-based Undergraduate Research Experience (CURE) in an introductory epidemiology course examine factors considered important regarding their...
It is well-documented that participation in leisure activities plays an essential role coping with stress and improving health. However, we know less about what types of are more relevant to life satisfaction happiness among college students. Thus, the purpose this study was investigate how various relate Data were collected using a sample 266 Indiana, United States. Results from hierarchical multiple regression analysis indicate certain (i.e. outdoor, sports, social, cultural civic...
Disruption of polyubiquitin gene Ubb leads to early-onset reactive gliosis and adult-onset hypothalamic neurodegeneration in mice. However, it remains unknown why reduced levels ubiquitin (Ub) due loss lead these neural phenotypes. To determine whether or not the defects neurons their progenitors per se, but cellular microenvironment, are cause phenotypes observed Ubb−/− mice, we investigated properties cultured cells isolated from mouse embryonic brains. Although were under conditions...
Abstract This study examines the solution for one of most difficult problems electroforming process “thickness deviation”. As an effective solution, auxiliary electrode (dummy cathode) is considered. Generally, thickness edge plating area almost twice center or greater. An (intentionally attached dummy has helped to achieve more uniform electroformed-nickel layer by preventing excessive electric charge. In addition, computer-aided analysis was performed determine optimal condition and...
Engaging key populations, including gender and sexual minorities, is essential to meeting global targets for reducing new HIV infections improving the continuum of care. Negative attitudes toward minorities serve as a barrier political will effective programming health services. The President's Emergency Plan AIDS Relief (PEPFAR), established in 2003, provided Gender Sexual Diversity Trainings 2,825 participants PEPFAR staff program implementers, U.S. government staff, local stakeholders 38...
Indole, which is widespread in microbial communities, has received attention because of its effects on bacterial physiology. Pseudomonas putida and aeruginosa can acquire ampicillin (Amp) resistance during growth indole-Amp agar. Transcriptome, mutant, inhibitor studies have suggested that Amp induced by indole be attributed to increased gene expression ttgAB encoding two genes RND-type multidrug efflux operons an ampC β-lactamase. Expression, enzyme activities, mutational analyses indicated...
A novel bacterial strain, designated PR1016AT, was isolated from a car air conditioning system. This rod-shaped strain showed catalase and oxidase activities, aerobic methylotrophic, had reddish pink colour. The genomic DNA G+C content of PR1016AT 70.2 mol%, as determined by genome sequencing. Phylogenetic analysis based on 16S rRNA gene sequence similarity that most closely related to Methylobacterium aquaticum GR16T (98.86 %), M. variabile GR3T (98.43 platani PMB 02T (98.36 %) tarhaniae...
At present, over 215 million people live outside their countries of birth, many which are referred to as diaspora-those that in host but maintain strong sentimental and material links with origin, homelands. The critical shortage Human Resources for Health (HRH) developing remains a barrier attaining health system goals. Usage medical diaspora can be one way meet this need. A growing number policy-makers have come acknowledge play vital role the development homeland's workforce capacity. To...
(1) Background: As gaps in the public health workforce grow wake of COVID-19 pandemic, graduates schools health, especially Doctors Public Health (DrPH), are poised to offer relief. While there some known recruitment issues, student debt and impact on career choices understudied. (2) Methods: In present study, we perform a descriptive analysis potential among DrPH students alumni United States using cross-sectional national online survey. A total 203 participants (66: 137: current students)...
A novel bacterial strain, designated AK13T (=KACC 21401T=DSM 109981T), was isolated from the rhizosphere of Miscanthus sacchariflorus. Strain found to be an aerobic, Gram-stain-positive, endospore-forming and rod-shaped bacterium. It formed yellow circular colonies with smooth convex surfaces. The genomic DNA G+C content strain estimated 40 mol%. Phylogenetic analysis based on 16S rRNA gene sequence similarity showed that this most closely related Bacillus lehensis MLB2T (99.4 %), oshimensis...
Abstract Cellular senescence of the retinal pigment epithelium (RPE) is thought to play an important role in vision-threatening degenerative diseases, such as age-related macular degeneration (AMD). However, single-cell RNA profiles control RPE tissue and exhibiting cellular are not well known. We have analyzed transcriptomes mice with low-dose doxorubicin (Dox)-induced (Dox-RPE). Our results identified 4 main subpopulations that exhibit heterogeneous biological activities roles ATP...
Abstract Background Since the Immigration and Nationality Act of 1952, number international students in United States had been gradually increasing. However, total numbers have begun to decrease since 2019–2020 school year due Trump administration's policy COVID-19. Still, little is known about how students’ psychological adjustment well-being affected by changing nonimmigrant visa COVID-19 pandemic.
