Controlled Differentiation of Human Neural Progenitor Cells on Molybdenum Disulfide/Graphene Oxide Heterojunction Scaffolds by Photostimulation.

Ultrathin MoS-MoO heterojunction nanosheets with unique features were introduced as biocompatible, non-cytotoxic, and visible light-sensitive stimulator layers for the controlled differentiation of human neural progenitor cells (hNPCs) into nervous lineages. hNPC differentiation was also investigated on reduced graphene oxide (rGO)-containing scaffolds, that is, rGO and rGO/MoS-MoO nanosheets. In darkness, hNPC differentiation into neurons increased on MoS-MoO by a factor of 2.

Current knowledge of physicians' dual practice in Iran: A scoping review and defining the research agenda for achieving universal health coverage.

Background: Physicians' dual practice (simultaneous practice in both public and private sectors) may be challenging for achieving universal health coverage. The purpose of this review is to identify the types of available evidence in physicians' dual practice in Iran and define the research agenda for achieving universal health coverage (UHC).

Methods: We conducted a scoping review of the literature using Arksey and O'Malley's approach.

The effects of beta-cell mass and function, intercellular coupling, and islet synchrony on [Formula: see text] dynamics.

Type 2 diabetes (T2D) is a challenging metabolic disorder characterized by a substantial loss of [Formula: see text]-cell mass and alteration of [Formula: see text]-cell function in the islets of Langerhans, disrupting insulin secretion and glucose homeostasis. The mechanisms for deficiency in [Formula: see text]-cell mass and function during the hyperglycemia development and T2D pathogenesis are complex. To study the relative contribution of [Formula: see text]-cell mass to [Formula: see text]-cell function in T2D, we make use of a comprehensive electrophysiological model of human [Formula: see text]-cell clusters.

Graphene Jet Nanomotors in Remote Controllable Self-Propulsion Swimmers in Pure Water.

A remote controllable working graphite nanostructured swimmer based on a graphene jet nanomotor has been demonstrated for the first time. Graphite particles with pyramidal-like morphologies were fabricated by the creation of suitable defects in wide high-purity graphite flakes followed by a severe sonication. The particles were able to be self-exfoliated in water after Na intercalation between the graphene constituents.
