Fragmentation of continental subduction is ending the Himalayan orogeny.

After two continents collide, plate convergence and orogenesis are sustained because subducted continental lithosphere continues pulling the surface plate. It remains controversial how, why, and when continental plate convergence and collision slow down and eventually cease. We use an unprecedented data coverage and present a regional-scale seismic tomographic image of the mantle structure beneath the Tibetan Plateau.

Spatiotemporal variation in nitrogen and phosphorus levels and microbial community in the upstream water transport channel to the Douhe Reservoir.

The Douhe Reservoir is an important diversion water source and drinking water resource for Tianjin and the Tangshan cities. Panjiakou, Daheiting, Qiuzhuang, and the Douhe Reservoirs located from top to bottom in the LuanHe River region forming a group of cascade reservoirs. After over 30 years of aquaculture, the concentration of nitrogen (N) and phosphorus (P) have exceeded Class III of Environmental Quality Standard for Surface Water in China.

Importance of the creation of a short musculofascial tunnel in peritoneal dialysis catheter placement.

Background: Peritoneal dialysis (PD) catheter migration impedes the efficacy of dialysis. Therefore, several techniques involving additional sutures or incisions have been proposed to maintain catheter position in the pelvis.

Aim: To evaluate the efficacy of creating a short musculofascial tunnel beneath the anterior sheath of the rectus abdominis during PD catheter implantation.

Effects of situational simulation and online first-aid training programs for nurses in general medical wards: A prospective study.

Background: To maintain patient safety, effective first-aid skills are necessary during emergencies. It is important to develop in-service education programs to equip clinical nurses with first-aid skills.

Objectives: This study explored the effects of first-aid skills and knowledge between situational simulation training and online teaching.

Dysregulated NF-κB signal promotes the hub gene PCLAF expression to facilitate nasopharyngeal carcinoma proliferation and metastasis.

Background: Nasopharyngeal carcinoma (NPC) is common in Southern China. The molecular mechanism underlying NPC genesis and progression has been comprehensively investigated, but the key gene (s) or pathway (s) pertaining to NPC are unidentified.

Methods: We explored some key genes and pathways involved in NPC through using meta-analysis of deposited expression of microarray data of NPC.

Protective Effects of Naringin in Cerebral Infarction and Its Molecular Mechanism.

BACKGROUND Cerebral infarction is a cardiovascular disease with high morbidity and mortality. At present, many studies have reported the treatment of cerebral infarction by traditional Chinese medicine. Naringin, a flavonoid, is a major traditional Chinese medicine.

Using Methacryl-Polyhedral Oligomeric Silsesquioxane as the Thermal Stabilizer and Plasticizer in Poly(vinyl chloride) Nanocomposites.

In this study, we investigated the influence of methacryl-functionalized polyhedral oligomeric silsesquioxane (MA-POSS) nanoparticles as a plasticizer and thermal stabilizer for a poly(vinyl chloride) (PVC) homopolymer and for a poly(vinyl chloride)/dissononyl cyclohexane-1,2-dicarboxylate (PVC/DINCH) binary blend system. The PVC and the PVC/DINCH blend both became flexible, with decreases in their glass transition temperatures and increases in their thermal decomposition temperatures, upon an increase in MA-POSS content, the result of hydrogen bonding between the C=O groups of MA-POSS and the H-CCl units of the PVC, as determined using infrared spectroscopy. Furthermore, the first thermal decomposition temperature of the pure PVC, due to the emission of HCl, increased from 290 to 306 °C, that is, the MA-POSS nanoparticles had a retarding effect on the decomposition of the PVC matrix.

Detection of autoantibodies and increased concentrations of interleukins in plasma from patients with Tourette's syndrome.

The aim of this study was to assess levels of autoantibodies and cytokines in patients with Tourette's syndrome (TS, n = 40) and healthy control individuals (n = 40). Plasma interleukin (IL)-1β, IL-6, IL-17, and soluble gp130 concentrations were significantly higher in the TS group compared with the control group (P < 0.001); whereas the soluble IL-6 receptor concentration was significantly decreased in the TS group compared with the control group (P < 0.
