Schisandrin B (SchB) is an active lignan component from Schisandra chinensis Turcz. Baill that has been long used as Traditional Chinese Medical Herb in the prescriptions for "tranquilizing the mind and overcoming anxiety". Given that SchB is one of the most abundant ingredients of Schisandra chinensis Baill, we examined the sedative and hypnotic effects of SchB and explored the underlying mechanism. The results showed that SchB can significantly decrease mouse locomotor activities and improved sleeping quality index, including increased number of sleeping mice treated with the subthreshold dose of pentobarbital sodium, increased sleep time, shortened sleep latency and prolonged sleep duration...

The molecular mechanisms underlying susceptibility to severe respiratory syncytial virus (RSV) infection remain poorly understood. Herein, we report on the role of osteopontin (OPN) in regulation of RSV infection in human epithelial cells and how interleukin-1 beta (IL-1β), a cytokine secreted soon after RSV infection, when persistently expressed can induce OPN expression leading to increased viral infection. We first compared OPN expression in two human epithelial cell lines: HEK-293 and HEp-2. In contrast to HEp-2, HEK-293 expresses low levels of pro-caspase-1 resulting in decreased IL-1β expression in response to RSV infection...

Haibing Wang, Gaochenxi Zhang
β,β-Dimethylacrylshikonin (DMAS) is an anti-cancer compound extracted from the roots of Lithospermum erythrorhizon. This study aims to investigate the effects of DMAS on human lung adenocarcinoma cells in vitro and explored the mechanisms of its anti-cancer action. We demonstrated that DMAS markedly inhibited cell viability in a dose- and time-dependent manner, and induced apoptosis as well as autophagy in human lung adenocarcinoma cells. Furthermore, we found that DMAS stimulated endoplasmic reticulum (ER) stress and mediated autophagy via the PERK-eIF2α-ATF4-CHOP and IRE1-TRAF2-JNK axises of the unfolded protein response (UPR) in human lung adenocarcinoma cells...

Nedim Durmus, Gabriele Grunig
Detrimental effects of air pollution with fine dust (particulate matter ≤2.5 μm in aerodynamic diameter, or PM2.5 ) on the systemic circulation and the left heart have been studied intensely during the past decade. In comparison, knowledge regarding the effects of exposure to air pollution with PM2.5 on the pulmonary vasculature and the right heart lags far behind. A report on severe lung disease and right heart failure in coal miners was published nearly 170 years ago. However, today, we still do not have a clear picture of how the effect of air pollution on the pulmonary circulation or the right heart should be viewed from a clinical, mechanistic biological, therapeutic, or economic angle...

Bioelectricity plays a vital role in living organisms. Although electrical stimulation is introduced in the field of bone regeneration, the concept of a dose-response relationship between surface potential and osteogenesis is not thoroughly studied. To optimize the osteogenic properties of different surface potentials, a flexible piezoelectric membrane, poly(vinylidene fluoridetrifluoroethylene) [P(VDF-TrFE)], is fabricated by annealing treatment to control its β phases. The surface potential and piezoelectric coefficients (d33 ) of the membranes can be regulated by increasing β phase contents...

PURPOSE: During head and neck cancer treatment, the radiation response of the oral mucosa represents a frequent early side effect. Besides radiation-induced inhibition of proliferation, various other cellular responses occur. The radiation response of adherens and tight junction proteins was so far mostly investigated with large single-dose irradiation protocols, in vivo and in vitro. Therefore, the current study was initiated to investigate the impact of daily fractionated irradiation on the expression of adherens and tight junction proteins in vivo...
