Near-Surface Concentration Profile of Sheared Semidilute Polymer Solutions.

Controlling the structure of polymer solutions near a solid surface is crucial for many industrial processes as it significantly impacts solution flow and influences slip at the interface. To date, only a few techniques have been developed to experimentally investigate this type of interface at the nanometric scale of solid/liquid interactions. In this study, we probe the interface between a smooth sapphire surface and a semidilute polystyrene solution, using neutron reflectivity.

Sport participation, weight status, and physical fitness in French adolescents.

The primary objective of this study was to investigate the associations between sport participation and weight status with physical fitness among French adolescents. The secondary aim was to establish sex- and age-specific physical fitness percentiles for French adolescents. The sample comprised 8084 adolescents (4126 boys, 3958 girls), aged 10-14 years.

Generation of a human induced pluripotent stem cell line UGENTi002-A from an arrhythmogenic cardiomyopathy patient carrying the c.817C>T DSP heterozygous variant and isogenic control using CRISPR/Cas9 editing.

Arrhythmogenic cardiomyopathy is a severe genetic heart muscle disease characterized by fibro-fatty replacement of the myocardium. Pathogenic variants causal for this disease are mainly located in desmosomal genes, including desmoplakin (DSP). Renal epithelial cells were isolated from a patient carrying the heterozygous c.

Regulation of potassium uptake in .

Potassium (K) is an essential physiological element determining membrane potential, intracellular pH, osmotic/turgor pressure, and protein synthesis in cells. Here, we describe the regulation of potassium uptake systems in the oligotrophic α-proteobacterium known as a model for asymmetric cell division. We show that can grow in concentrations from the micromolar to the millimolar range by mainly using two K transporters to maintain potassium homeostasis, the low-affinity Kup and the high-affinity Kdp uptake systems.

Introduction: The aim of this study was to analyze the rate of enhanced recovery programs (ERP) implementation in a range of surgical specialties in both the public and private sectors.

Methods: This was a retrospective longitudinal study based on hospital stays between March to December 2019. We studied thirteen of the activity segments most frequently included in ERP protocol.
