Molecular characterization of patients with chronic hepatitis C virus infection in Jordan: implications on response to direct-acting antiviral therapy.

Objectives: To investigate the molecular characteristics of Hepatitis C Virus (HCV) detected in patients with chronic HCV infection in Jordan.

Methods: The study included 48 Jordanian treatment-naïve patients with active chronic HCV recruited from seven governorates. HCV genotype and the resistance-associated substitutions (RAS) profile were investigated by next-generation sequencing of the NS5B, NS5A, and NS3 regions of HCV.

Quantum Tunneling-Induced Membrane Depolarization Can Explain the Cellular Effects Mediated by Lithium: Mathematical Modeling and Hypothesis.

Lithium imposes several cellular effects allegedly through multiple physiological mechanisms. Membrane depolarization is a potential unifying concept of these mechanisms. Multiple inherent imperfections of classical electrophysiology limit its ability to fully explain the depolarizing effect of lithium ions; these include incapacity to explain the high resting permeability of lithium ions, the degree of depolarization with extracellular lithium concentration, depolarization at low therapeutic concentration, or the differences between the two lithium isotopes Li-6 and Li-7 in terms of depolarization.
