Peak fat oxidation is positively associated with vastus lateralis CD36 content, fed-state exercise fat oxidation, and endurance performance in trained males.

Eur J Appl Physiol 2021 Sep 25. Epub 2021 Sep 25.

Sports Performance Research Institute New Zealand, Auckland University of Technology, Auckland, New Zealand.

Environ Sci Pollut Res Int 2021 Sep 24. Epub 2021 Sep 24.

Chitkara College of Pharmacy, Chitkara University, Chandigarh, Punjab, India.

The aim of the study was to evaluate the effects of NO modulators and antioxidant treatments on endocrine (plasma corticosterone), cellular (heat shock protein 70 [HSP-70] and nuclear factor κB [NF-κB]), and oxidative stress markers in repetitively stressed rats. Repetitive (restraint) stress (RS 1hr/day × 21 days) enhanced the levels of cellular and endocrine stress markers in the rat blood and altered pro-oxidant-antioxidant balance differentially in the control and test groups. Exposure to repetitive RS enhanced malondialdehyde (MDA) levels, lowered reduced glutathione (GSH), and superoxide dismutase (SOD) levels as well as nitric oxide (NOx) levels. Read More

Psychological Problems Mediate the Relationship Between Minority Stress and HIV Sexual Risk Among Nigerian Men Who Have Sex with Men: Testing the Minority Stress Model.

Arch Sex Behav 2021 Sep 24. Epub 2021 Sep 24.

Department of Behavioral and Social Sciences, Brown University School of Public Health, 121 South Main St., Box G-S121-3, Providence, RI, 02912, USA.

Gay, bisexual, and other men who have sex with men (GBMSM) in Nigeria bear a disproportionately higher burden of HIV. Meyer's minority stress theory posits that social stress due to the discrimination, violence, and stigma experienced by lesbian, gay, and bisexual men and women (LGBs)-due to their sexual orientation-may contribute to psychological problems, including mental health problems, substance use, and HIV sexual risk-taking. Between March and June 2019, we recruited 406 GBMSM from four states in Nigeria (Abuja, Delta, Lagos, and Plateau) to complete a cross-sectional survey at local community-based organizations.

Protocol for a feasibility randomized trial of self-management support for people with chronic obstructive pulmonary disease using lay health coaches.

Contemp Clin Trials 2021 Sep 21;110:106570. Epub 2021 Sep 21.

Division of General Internal Medicine, Icahn School of Medicine at Mount Sinai, New York, NY, United States of America.

Challenges with self-management are a major contributor to poor outcomes among adults with chronic obstructive pulmonary disease (COPD). The causes of poor self-management in COPD are manifold, and they arise from physical, cognitive, socioeconomic, environmental and societal sources. To address this complexity, we developed the Supporting self-Management Behaviors in Adults with COPD (SaMBA-COPD) model, which uses lay health coaches to identify a patient's barriers to effective COPD self-management and provide tailored support to help them overcome those barriers, reduce their symptoms and need for urgent care and improve their quality of life.

Interactions of noradrenergic, glucocorticoid and endocannabinoid systems intensify and generalize fear memory traces.

Neuroscience 2021 Sep 21. Epub 2021 Sep 21.

Departamento de Farmacologia, Universidade Federal de Santa Catarina, Florianópolis, SC, Brazil. Electronic address:

Systemic administration of drugs that activate the noradrenergic or glucocorticoid system potentiates aversive memory consolidation and reconsolidation. The opposite happens with the stimulation of endocannabinoid signaling under certain conditions. An unbalance of these interacting neurotransmitters can lead to the formation and maintenance of traumatic memories, whose strength and specificity attributes are often maladaptive. Read More

Med Sci Sports Exerc 2021 Sep 17. Epub 2021 Sep 17.

Department of Neurosciences, Biomedicine, and Movement, University of Verona, Italy Department of Internal Medicine, University of Utah, Salt Lake City, UT.

Purpose: Given the increased level of fatigue frequently reported by patients with Parkinson's disease (PD), this study investigated the interaction between central and peripheral components of neuromuscular fatigue (NF) in this population, compared to healthy peers.

Methods: Changes in maximal voluntary activation (ΔVA, central fatigue) and potentiated twitch force (ΔQtw,pot, peripheral fatigue) pre-post exercise were determined via the interpolated twitch technique in 10 patients with PD and 10 healthy controls (CTRL) matched for age, sex and physical activity. Pulmonary gas exchange, femoral blood flow (FBF), and quadriceps electromyography (EMG) were measured during a fatiguing exercise (85% of peak power output (PPO)). Read More

Muscle mitochondrial catalase expression prevents neuromuscular junction disruption, atrophy, and weakness in a mouse model of accelerated sarcopenia.

J Cachexia Sarcopenia Muscle 2021 Sep 24. Epub 2021 Sep 24.

Aging & Metabolism Research Program, Oklahoma Medical Research Foundation, Oklahoma City, OK, USA.

Background: Oxidative stress and damage are associated with a number of ageing phenotypes, including age-related loss of muscle mass and reduced contractile function (sarcopenia). Our group and others have reported loss of neuromuscular junction (NMJ) integrity and increased denervation as initiating factors in sarcopenia, leading to mitochondrial dysfunction, generation of reactive oxygen species and peroxides, and loss of muscle mass and weakness. Previous studies from our laboratory show that denervation-induced skeletal muscle mitochondrial peroxide generation is highly correlated to muscle atrophy. Read More

Sex-specific effects of low-dose hydrocortisone on threat detection in HIV.

J Neurovirol 2021 Sep 24. Epub 2021 Sep 24.

Department of Neurology, Johns Hopkins University School of Medicine, 600 North Wolfe Street, Meyer 6-113a, Baltimore, MD, 21287, USA.

One sex differences in the perception of emotion is that females, particularly those with high anxiety, often show heightened identification of fearful faces. To better understand the causal role of glucocorticoids in this sex difference, we examine these associations in people with HIV(PWH) where emotion perception is impaired and mental health disorders are frequent. In a double-blind, placebo-controlled, cross-over study, we used a single low-dose of hydrocortisone (10 mg; LDH) as a mechanistic probe of the effects of elevated glucocorticoids on negative emotion perception in 65 PWH (31 women).
