The effect of water-soluble synthetic antioxidant TS-13 (sodium 3-(3'-tert-butyl-4'-hydroxyphenyl) propyl thiosulfonate) on life span of different lines of Drosophila melanogaster under normal conditions and survival under oxidative stress induced by hydrogen peroxide and paraquat has been investigated. Introduction to the diet of 1% TS-13 prolonged the life span of males and females of D. melanogaster long-living line Canton S, had no effect on short-living Oregon R life span and reduced the life span of male D. melanogaster line IgI(558)OR/Cy, heterozygous on tumor suppressor recessive lethal mutation. When flies were exposed to hydrogen perexide, TS-13 significantly enhanced Canton Smale and Oregon R female survival. Under the influence of paraquat antioxidant protected Canton S female and Oregon R flies of both sexes. Despite the fact that the anti-aging and protective properties of synthetic phenol antioxidant TS-13 depend essentially on the genotype and gender, in the extreme conditions of oxidative stress its positive effect pronounced.

Background: Both air pollution and low socioeconomic status (SES) are associated with worse cognitive function. The extent to which low SES may compound the adverse effect of air pollution on cognitive function remains unclear.
Methods: 7,087 older adults aged 65 and above were included from the Chinese Longitudinal Healthy Longevity Survey (CLHLS) and followed up in 4 waves during 2008-2018.

Alternatives to nonbiodegradable synthetic plastics for food packaging include films made from biopolymers that are nontoxic and environment-friendly. In this study, carnauba wax (CW) and nitrogen-doped graphene quantum dots (NG) as functional additives were utilized in the production of pectin/gelatin (PG) film. NG was synthesized through the microwave method, using acetic acid as the carbon source, giving size, and zeta potential of 1.

In this cross-sectional analysis, we explored how fluctuations in glycemic levels impact executive functions and psychosocial outcomes in patients with type 2 diabetes mellitus (T2DM). The goal was to understand the relationship between glycemic control and both neuropsychological and psychosocial health. We stratified participants into well-controlled and poorly controlled groups based on glycated hemoglobin (HbA1c) levels and variability, including a healthy control group for comparison.

Purpose Of Review: Early identification of cerebral palsy (CP), as in all neurologic conditions, has a profound impact on the ability to initiate interventions, support the education and empowerment of parents, ameliorate the effect of the conditions, and importantly identifies cohorts for neuroprotection or repair to address the primary injury. CP is a life span condition. Rapid initiation of services, support and anticipatory guidance is essential to maximize functional outcomes, prevent or manage complications and improve quality of life.

Objective: Peripheral intravenous catheter (PIVC) failure occurs in approximately 50% of insertions. Unexpected PIVC failure leads to treatment delays, longer hospitalizations, and increased risk of patient harm. In current practice there is no method to predict if PIVC failure will occur until it is too late and a grossly obvious complication has occurred.
