Background And Aim: Postural stability during gait is a crucial factor that reduces the risk of falls. Researchers determine the most effective way to assist patients whose postural stability deficit predominantly related to gait parameters. The aim of this study was to investigate the comparison and relationship between spatiotemporal gait parameters and postural stability in young male and female.

Immediate and Long-Term Effectiveness of Proprioceptive Neuromuscular Facilitation and Static Stretching on Joint Range of Motion, Flexibility, and Electromyographic Activity of Knee Muscles in Older Adults.

Previously, various stretching techniques were compared to study their effects on the different physiological parameters of hamstring muscles in the elderly population. There is no research that compares the immediate and long-term effects of proprioceptive neuromuscular facilitation-contract-relax (PNF-CR) and static stretching (SS) techniques on knee range of motion (ROM), hamstring flexibility, and knee flexor muscle EMG activity in the elderly. This study intends to compare the same.

A systematic review of effects of daytime napping strategies on sports performance in physically active individuals with and without partial-sleep deprivation.

Background: Sleep is the body's natural recovery process, restoring routine metabolic and regulatory functions. Various sleep interventions have been developed to facilitate recovery, and athletic performance, and daytime napping are among them. However, due to inconsistencies in studies, it remains unclear whether daytime napping affects sports performance.

Efficacy of core stability training on upper extremity performance in collegiate athletes.

Objective: To determine the efficacy of a five-week core stability training program for collegiate athletes on upper extremity performance measures.

Methods: Seventy healthy collegiate athletes (age 21.6±1.

Short-Term Effects of Dry Needling with a Standard Exercise Program on Pain and Quality of Life in Patients with Chronic Mechanical Neck Pain.

Background: This study aimed to determine the short-term effects of dry needling (DN) combined with a standard exercise program on pain and quality of life in patients with chronic mechanical neck pain (CMNP).

Methods: Thirty-one patients with CMNP were randomly allocated to the experimental and control groups. The experimental group received DN and underwent a standard exercise program (one DN session and six exercise sessions) for two weeks, whereas the control group underwent the same exercise program alone for two weeks.

Characteristics and Predictors of Late Right Heart Failure After Left Ventricular Assist Device Implantation.

Late right heart failure (LRHF) following left ventricular assist device (LVAD) implantation remains poorly characterized and challenging to predict. We performed a multicenter retrospective study of LRHF in 237 consecutive adult LVAD patients, in which LRHF was defined according to the 2020 Mechanical Circulatory Support Academic Research Consortium guidelines. Clinical and hemodynamic variables were assessed pre- and post-implant.

Synthesis of Chitosan-Silver Nanoparticle Composite Spheres and Their Antimicrobial Activities.

Synthesis of silver nanoparticles-chitosan composite particles sphere (AgNPs-chi-spheres) has been completed and its characterization was fulfilled by UV-vis spectroscopy, Fourier transform infrared (FT-IR) spectroscopy, X-ray diffraction (XRD), scanning electron microscopy (SEM), and zetasizer nano. UV-vis spectroscopy characterization showed that AgNPs-chi-spheres gave optimum absorption at a wavelength of 410 nm. The XRD spectra showed that the structure of AgNPs-chi-spheres were crystalline and spherical.

Less invasive surgical implant strategy and right heart failure after LVAD implantation.

Background: Conventional median sternotomy (CMS) is still the standard technique utilized to implant left ventricular assist devices (LVADs). Recent studies suggest that less invasive surgery (LIS) may be beneficial; however, robust data on differences in right heart failure (RHF) are lacking. This study aimed to determine the impact of LIS compared with that of CMS on RHF outcomes after LVAD implantation.

Evaluation of patients with a HeartMate 3 left ventricular assist device using echocardiographic particle image velocimetry.

The effect of column and temperature variation on the determination of the dead time in gas chromatographic systems using indirect methods.

The precise determination of the dead time is essential in a chromatography system as it is a primary parameter for the determination of other secondary parameters such as the adjusted retention time, relative retention time, retention factor and retention index. Several of the indirect methods used for the determination of the dead time in this study were iteration, nonlinear, spreadsheet and statistics methods, which were implemented using the ANSI C programming language. The calculation of each method was tested with temperature and column variations for measuring the retention time of a n-alkane homologous series and accuracy analysis of each mathematical method (indirect method) to the marker substance (direct method).
