The Influence of Aging on Hip Abductor Muscle Torque, Power, Velocity and the Association With Lower Limb Physical Function.

Background And Purpose: Muscle strength, power, and mass decline with aging, leading to functional loss highly correlated with balance and falls in older adults. Lower limb muscle function is critical for fall prevention in older adults, and hip abductor force and rapid force development have been shown to be important during stepping tasks. However, it remains unclear whether hip abductor muscle function changes with aging.

This study aimed to evaluate the impact of an intimate cleansing gel containing chlorhexidine, hyaluronic acid, and other anti-inflammatory agents (Antroclean Fisioderm) on postoperative pain, itching, and wound healing in patients who had undergone this procedure.

Methods: This multicenter observational case-control study involved a cohort of consecutive adult patients who underwent hemorrhoidectomy using an ultrasound device.

Effective Nitrate Electroconversion to Ammonia Using an Entangled CoO/Graphene Nanoribbon Catalyst.

There has been huge interest among chemical scientists in the electrochemical reduction of nitrate (NO) to ammonia (NH) due to the useful application of NH in nitrogen fertilizers and fuel. To conduct such a complex reduction reaction, which involves eight electrons and eight protons, one needs to develop high-performance (and stable) electrocatalysts that favor the formation of reaction intermediates that are selective toward ammonia production. In the present study, we developed and applied CoO/graphene nanoribbon (GNR) electrocatalysts with excellent properties for the effective reduction of NO to NH, where NH yield rate of 42.

Red Blood Cells Capture and Deliver Bacterial DNA to Drive Host Responses During Polymicrobial Sepsis.

Red blood cells (RBCs), traditionally recognized for their role in transporting oxygen, play a pivotal role in the body's immune response by expressing TLR9 and scavenging excess host cell-free DNA. DNA capture by RBCs leads to accelerated RBC clearance and triggers inflammation. Whether RBCs can also acquire microbial DNA during infections is unknown.

Loss of Surfactant Protein A Alters Perinatal Lung Morphology and Susceptibility to Hyperoxia-Induced Bronchopulmonary Dysplasia.

Bronchopulmonary dysplasia (BPD) is a condition of poor alveolar formation that causes chronic breathing impairment in infants born prematurely. Preterm lungs lack surfactant and are vulnerable to oxidative injuries driving the development of BPD. Our recent studies reported that surfactant protein A (SP-A) genetic variants influence susceptibility to neonatal lung disease.

Muscle hypertrophy response across four muscles involved in the bench press exercise: Randomized 10 weeks training intervention.

Background And Purpose: Resistance training exercise provides increases in muscle size and is used by coaches and health care professional as a tool to improve functional performance. The aim of the present study was to investigate the effect of 10 weeks of resistance training program performed on the bench press (BP) exercise on the hypertrophic responses of four different muscles (pectoralis major, anterior and medial deltoid, brachii, and pectoralis minor) involved in the task compared to controls.

Methods: Twenty-four healthy males were recruited, and thirteen performed a resistance training intervention while eleven were control.

Balancing Surface Chemistry and Flake Size of MXene-Based Electrodes for Bioelectrochemical Reactors.

MXenes have excellent properties as electrode materials in energy storage devices or fuel cells. In bioelectrochemical systems (for wastewater treatment and energy harvesting), MXenes can have antimicrobial characteristics in some conditions. Here, different intercalation and delamination approaches to obtain TiCT MXene flakes with different terminal groups and lateral dimensions are comprehensively investigated.

Inequities in neurological care: Access to services, care gaps, and other barriers-A systematic review.

Background And Purpose: Health disparities and inequities are an important and too long overlooked public health concern worldwide. These differences in health and health care can affect people with any disease, including neurological disorders. The aim of this systematic review is to provide an updated overview of the main health inequities faced by neurological patients worldwide, to plan valuable interventions.

Greater motor unit discharge rate during rapid contractions in chronically strength-trained individuals.

Though similar motor unit (MU) discharge properties have been observed during slow sustained contractions between chronically strength-trained (ST) and untrained (UT) individuals, it is currently unknown whether differences between these groups exist for when maximal in vivo MU discharge rate is assessed during rapid, maximal rate of force development (RFD) contractions. Therefore, we compared MU discharge characteristics and RFD during rapid contractions in chronic ST and UT individuals. The investigations were performed in two independent cohorts of chronically ST men, with trained elbow flexors (, = 13, 6 ± 4 yr of training experience) or knee extensors (, = 11, 9 ± 4 yr of experience), and compared with those of UT ( = 12 and = 10, respectively).

Intertwined Flexoelectricity and Stacking Ferroelectricity in Marginally Twisted hBN Moiré Superlattice.

Moiré superlattices in twisted van der Waals homo/heterostructures present a fascinating interplay between electronic and atomic structures, with potential applications in electronic and optoelectronic devices. Flexoelectricity, an electromechanical coupling between electric polarization and strain gradient, is intrinsic to these superlattices because of the lattice misfit strain at the atomic scale. However, due to its weak magnitude, the effect of flexoelectricity on moiré ferroelectricity has remained underexplored.

The Effect of Relative Humidity in Conductive Atomic Force Microscopy.

Conductive atomic force microscopy (CAFM) analyzes electronic phenomena in materials and devices with nanoscale lateral resolution, and it is widely used by companies, research institutions, and universities. Most data published in the field of CAFM is collected in air at a relative humidity (RH) of 30-60%. However, the effect of RH in CAFM remains unclear because previous studies often made contradictory claims, plus the number of samples and locations tested is scarce.
