Monolayer MoS with S vacancy defects doped with Group V non-metallic elements (N, P, As): a first-principles study.

Context: This study systematically investigated the effects of single S-atom vacancy defects and composite defects (vacancy combined with doping) on the properties of MoS using density functional theory. The results revealed that N-doped S-vacancy MoS has the smallest composite defect formation energy, indicating its highest stability. Doping maintained the direct band gap characteristic, with shifts in the valence band top.

Effectiveness of gua sha with Masanggoubang oil in rats with chronic soft tissue injury.

Background: Chronic soft tissue injury is characterized by sterile inflammation and pain. Gua sha with Masanggoubang oil (GSMO) treatment has been found to possess anti-inflammatory and analgesic effects.

Objectives: To explore the mechanism of GSMO in chronic soft tissue injuries.

Intrinsic Opening of BK Channels Derives from Inherent Leakage in Hydrophobic Gating.

The big potassium (BK) channels remain open with a small limiting probability of ∼ 10 at minimal Ca and negative voltages < -100 mV. The molecular origin and functional significance of such "intrinsic opening" are not understood. Here we combine atomistic simulations and electrophysiological experiments to show that the intrinsic opening of BK channels is an inherent property of the vapor barrier, generated by hydrophobic dewetting of the BK inner pore in the deactivated state.

Immunomodulatory effect of efferocytosis at the maternal-fetal interface.

Efferocytosis is a mechanism by which phagocytes efficiently clear apoptotic cells, averting their secondary necrosis and the subsequent release of potentially immunogenic or cytotoxic substances that can trigger strong immune and inflammatory responses. During efferocytosis, the metabolic pathways of phagocytes are transformed, which, along with the catabolism of apoptotic cargo, can affect their function and inflammatory state. Extensive apoptosis occurs during placental development, and some studies reported the immunomodulatory effects of efferocytosis at the maternal-fetal interface.

Higher potential leaching of inorganic and organic additives from biodegradable compared to conventional agricultural plastic mulch film.

Plastic mulch films support global food security, however, their composition and the potential release rates of organic, metal and metalloid co-contaminants remains relatively unknown. This study evaluates the low molecular weight organic additives, metal and metalloid content and leaching from low density polyethylene (LDPE) and biodegradable plastic mulch films. We identified 59 organic additives, and non-intentionally added substances in the new LDPE films (39.
