Nine polycyclic aromatic hydrocarbons (PAHs) and three nitro-polycyclic aromatic hydrocarbons (NPAHs) were detected by high-performance liquid chromatography with a fluorescence detector. The average concentrations of ∑PAHs and ∑NPAHs differed significantly both temporally and spatially and were the lowest in Kirishima during the warm period (∑PAHs: 0.

LIM kinases are involved in various cellular events such as migration, cycle, and differentiation, but whether they have a role in the specification of mammalian early endoderm remains unclear. In the present study, we found that depletion of LIMK2 severely inhibited the generation of definitive endoderm (DE) from human embryonic stem cells (hESCs) and promoted an early neuroectodermal fate. Upon the silencing of LIMK2 during the endodermal differentiation, the assembly of actin stress fibers was disturbed, and the phosphorylation of cofilin was decreased.

The results showed that the free drinking of 10 mM sucralose solution, 100 mM maltose solution, 3 mM saccharin solution and 3 g/L stevioside solution for 32 days will not affect the normal development of the body weight and feed intake of the mice. The consumption of maltose solution was significantly higher than that of the other sweeteners.

However, it remains challenging to develop flexible and lightweight CPCs with excellent stretchability, breathability, durability, and high EMI shielding effectiveness (EMI SE). Here, we propose a facile polyvinylpyrrolidone (PVP) assisted preparation of highly electrically conductive and durable nanofiber composites for high performance EMI shielding.

The data here described are related to the research article entitled "Molecular dynamics insights into binding selectivity of inhibitors toward BRD4 and CBP" [1]. Bromodomain-containing protein 4 (BRD4) and CREB binding protein (CBP) play important roles in tumorigenesis and development. We performed 200-ns molecular dynamics (MD) simulations on three pairs of inhibitor-BRD4 and inhibitor-CBP complexes to clarify binding selectivity of inhibitors toward BRD4 and CBP.

Background: To date, variables predicting the recovery of dysphagia in patients after dysphagic stroke have not been well defined. However, despite the difficulties in predicting and understanding the dysphagia recovery trajectory, its significance for stroke care cannot be understated. This study aims to identify the factors for functional swallowing recovery and develop nomograms that predict dysphagia recovery after stroke.

Polycyclic aromatic hydrocarbons (PAHs) are a class of important organic pollutants widely emitted from anthropogenic activities, with a general distribution in the gas and particulate phases. Some PAHs are carcinogenic, teratogenic, and mutagenic. Inhalation exposure to PAHs is correlated with adverse health outcomes in the respiratory and cardiovascular systems.

Particulate matter (PM) is a major factor contributing to air quality deterioration that enters the atmosphere as a consequence of various natural and anthropogenic activities. In PM, polycyclic aromatic hydrocarbons (PAHs) represent a class of organic chemicals with at least two aromatic rings that are mainly directly emitted via the incomplete combustion of various organic materials. Numerous toxicological and epidemiological studies have proven adverse links between exposure to particulate matter-bound (PM-bound) PAHs and human health due to their carcinogenicity and mutagenicity.

However, molecular mechanisms whereby SO influences its upper-stream targets have been elusive. Here we show that SO may mediate conversion of hydrogen peroxide (HO) to a more potent oxidant, peroxymonosulfite, providing a pathway for activation of HO to convert the thiol group of protein cysteine residues to a sulfenic acid group, aka cysteine sulfenylation.
