Fluorescence Correlation Spectroscopy Reveals Survival Motor Neuron Oligomerization but No Active Transport in Motor Axons of a Zebrafish Model for Spinal Muscular Atrophy [PDF]

Frontiers in Cell and Developmental Biology, 2021
Spinal Muscular Atrophy (SMA) is a progressive neurodegenerative disease affecting lower motor neurons that is caused by a deficiency in ubiquitously expressed Survival Motor Neuron (SMN) protein.

Chemically Fueled Active Transport. [PDF]

Angew Chem Int Ed Engl
Abstract Biology uses chemical potential differences from molecules like ATP to drive membrane pumps, transporting molecules across membranes even against concentration gradients. Here, we report a synthetic system that transports small molecules from an aqueous phase (the sender) to an aqueous receiver across a centimeter‐sized ...

Effects of Aqueous Boundary Layers and Paracellular Transport on the Efflux Ratio as a Measure of Active Transport Across Cell Layers [PDF]

Pharmaceutics
The efflux ratio (ER), determined by Caco-2/MDCK assays, is the standard in vitro metric to establish qualitatively whether a compound is a substrate of an efflux transporter.

Practical significance of individual blood pressure trajectories [PDF]

Българска кардиология, 2023
Individual blood pressure values tend to be close to a certain population pattern (because of environmental and socioeconomic factors), without fully following it (because of specifi c individual genetic predisposition).

Role of Sociodemographic Variables and the Mother's Active Behavior on Active Commuting to School in Children and Adolescents

Frontiers in Pediatrics, 2022
The main objective of the current study was to analyze how parents' sociodemographic characteristics, mode of commuting and physical activity (PA) act as indicators of active commuting to school (ACS) in their children and adolescents.

Numerical Study of Voltage-Gated Ca²⁺ Transport Irradiated by Terahertz Electromagnetic Wave

IEEE Access, 2020
This paper simulates Ca2+ transmembrane transport through voltage-gated Ca2+ channels in response to terahertz electromagnetic irradiation. The active transport of Ca2+ ions is taken into considerations in the Ca2+ transport.
