The head lift exercise (HLE) is a head-raising workout performed in a supine position. This exercise facilitates activation of the submental muscles located above the hyoid bone in front of the neck. HLE is a potential method to improve the movement of the hyolaryngeal movement and swallowing functions. The purpose of this study was to investigate the effect of HLE on the hyolaryngeal movement and aspiration in patients with dysphagic stroke. A total of 27 patients with stroke were randomly assigned either into the experimental (n=13) or the control group (n=14)...

Circuit resistance training (CT) constitutes a high-intensity interval program commonly used to target weight loss; however, the loads and exercise patterns that maximize energy expenditure (EE) remain undetermined. We examined differences in EE among CT protocols using varying loads and contraction speeds in recreationally-trained males and females. Seven males (21.1 ± 0.5y) and eight females (20.0 ± 0.9y) performed three randomized CT protocols incorporating three circuits using heavy-load (80%1RM) explosive (HLEC), heavy-load, controlled (2s) (HLCC), and moderate-load (50%1RM) explosive contractions (MLEC)...

BACKGROUND: Previous studies showed higher risk of cardiovascular and cerebrovascular (CCV) events in primary aldosteronism compared with essential hypertension, but the patients of these studies were limited to primary aldosteronism patients with high plasma aldosterone concentration (PAC). The introduction of the aldosterone-renin ratio as the screening test for primary aldosteronism led to the recognition of primary aldosteronism patients with normal PAC (nPA). However, there is no information on the risk of primary aldosteronism including nPA...

BACKGROUND: Recent research has shown that of the 72% of American Internet users who have looked for health information online, 22% have searched for help to lose or control weight. This demand for information has given rise to many online weight management communities, where users support one another throughout their weight loss process. Whether and how user engagement in online communities relates to weight change is not totally understood. OBJECTIVE: We investigated the activity behavior and analyze the semantic content of the messages of active users in LoseIt (r/loseit), a weight management community of the online social network Reddit...

Pathological states in the organism, e.g., renal or hepatic diseases, cataract, dysfunction of coronary artery, diabetes mellitus, and also intensive workout, induce the structural modification of proteins called molecular ageing or N-A isomerization. The aim of this study was to analyze the structural changes of serum albumin caused by alkaline ageing using absorption, spectrofluorescence, and circular dichroism spectroscopy. The N-A isomerization generates significant changes in bovine (BSA) and human (HSA) serum albumin subdomains-the greatest changes were observed close to the tryptophanyl (Trp) and tyrosyl (Tyr) residue regions while a smaller change was observed in phenyloalanine (Phe) environment...
