Background: Aquatic training is known for its effective and gentle rehabilitation benefits, but its impact on athletes with chronic ankle instability (CAI) remains underexplored. This study compares the effects of water-based and land-based balance training on functional performance, dynamic balance, fear of reinjury, and quality of life in athletes with CAI.

Methods: Forty-one athletes with chronic ankle instability (CAI) were randomly assigned to water-based (WBBE, n = 21) or land-based (LBBE, n = 20) balance exercise groups, completing 24 sessions of 30-45 min over 8 weeks.

Given their potential as natural substitutes for artificial additives and their health advantages, the extraction of bioactive substances like polyphenols from plant sources is becoming more and more significant. Nevertheless, it is still difficult to achieve effective extraction with minimal time and energy. In order to optimize polyphenol extraction from ripe jamun fruit pulp, including traditional and ultrasound-assisted methods, this study assessed the prediction power of response surface methodology (RSM) and adaptive neuro-fuzzy inference systems (ANFIS).

The Heck reaction is one of the most well-known C-C (carbon-carbon) coupling reactions and was identified with the Nobel Prize in Chemistry in 2010. These reactions have been broadly utilized to prepare a different spectrum of heterocycles with applications in agrochemical and pharmaceutical industries. These reactions are commonly catalyzed by palladium due to its tolerance and expansive variousness of functional groups, which bears a remarkable power in creating C-C bonds.

Introduction: Obesity is a multifactorial disease caused by an interaction between genetic, environmental and behavioral factors. Polymorphisms of the two genes Circadian Locomotor Output Cycles Kaput (CLOCK) rs1801260 and Melanocortin-4-receptor (MC4R) rs17782313, are associated with obesity. Knowledge is limited on the interaction between CLOCK, MC4R and obesity.
