The Effect of 8 Weeks of Selected Exercises on Strength of the Hip Abductor Muscles and Balance in Healthy Elderly Women [PDF]

open access: yesSport Sciences and Health Research, 2016
Decreased postural balance and control in the elderly cause unpleasant complications such as falling and hip fracture. Given the importance of balance and strength in the elderly's health, the aim of study was the effect of 8 weeks of selected exercises ...

Influence of Visual Feedback On Dynamic Balance Control in Chronic Stroke Survivors [PDF]

open access: yes, 2016
Chronic stroke survivors have an increased incidence of falls during walking, suggesting changes in dynamic balance control post-stroke. Despite this increased incidence of falls during walking, balance control is often studied only in standing.

Quantitation of mitochondrial dynamics by photolabeling of individual organelles shows that mitochondrial fusion is blocked during the Bax activation phase of apoptosis [PDF]

open access: yes, 2004
A dynamic balance of organelle fusion and fission regulates mitochondrial morphology. During apoptosis this balance is altered, leading to an extensive fragmentation of the mitochondria.

Consistent or Balanced? On the Dynamics of Voluntary Contributions [PDF]

open access: yesSSRN Electronic Journal, 2014
We investigate the dynamic effects of a charitable lottery and an income tax on donations. The analysis is based on a two-round dictator game with the subject’s charity of choice as recipient and additional incentives in the first round only. The immediate effect of a charitable lottery leads to higher contributions and we cannot find substantial ...

Speciation Through the Lens of Population Dynamics: A Theoretical Primer on How Small and Large Populations Diverge

open access: yesPopulation Ecology, EarlyView.
Population size and dynamics fundamentally shape speciation by influencing genetic drift, founder events, and adaptive potential. Small populations may speciate rapidly due to stronger drift, whereas large populations harbor more genetic diversity, which can alter divergence trajectories. We highlight theoretical models that incorporate population size

The Effect of Fatigue Induced by Exhaustive Exercises on Dynamic Balance and Balance Recovery Time in Active Men with Genu Varum and Normal Knee [PDF]

open access: yesSport Sciences and Health Research, 2015
Balance plays a key role in daily and sports activities. The aim of this study was to investigate the effect of fatigue induced by exhaustive exercises on dynamic balance and balance recovery time in active men with genu varum and normal knee.

Evolutionary interplay between viruses and R‐loops

open access: yesFEBS Letters, EarlyView.
Viruses interact with specialized nucleic acid structures called R‐loops to influence host transcription, epigenetic states, latency, and immune evasion. This Perspective examines the roles of R‐loops in viral replication, integration, and silencing, and how viruses co‐opt or avoid these structures.

Mechanisms and kinetic assays of aminoacyl‐tRNA synthetases

open access: yesFEBS Letters, EarlyView.
Accurate protein synthesis is crucial for life. The key players are aminoacyl‐tRNA synthetases (AARSs), which read the genetic code by pairing cognate amino acids and tRNAs. AARSs establish high amino acid selectivity by employing physicochemical limits in molecular recognition.

A Hidden Markov Model Based Detecting Solution for Detecting the Situation of Balance During Unsupported Standing Using the Electromyography of Ankle Muscles

open access: yesInternational Clinical Neuroscience Journal, 2022
Background: In this study, three detecting approaches have been proposed and evaluated for online detection of balance situations during quiet standing.

Trunk motion visual feedback during walking improves dynamic balance in older adults: Assessor blinded randomized controlled trial. [PDF]

open access: yes, 2018
BACKGROUND: Virtual reality and augmented feedback have become more prevalent as training methods to improve balance. Few reports exist on the benefits of providing trunk motion visual feedback (VFB) during treadmill walking, and most of those reports ...
