Our pilot study suggested that noninvasive ventilation (NIV) reduced the need for intubation compared with conventional administration of oxygen on patients "early" stage mild acute respiratory distress syndrome (ARDS, PaO2/FIO2 between 200 and 300). To evaluate whether early NIV can reduce invasive in pneumonia-induced ARDS. Prospective, multicenter, randomized controlled trial (RCT) through a Venturi mask. Primary outcome included numbers who met criteria. Two hundred subjects were to (n =...

Introduction of alkyl substituents onto nucleophilic nitrogen atoms in amines is a central synthetic strategy for increasing molecular complexity and structural diversity medicinal chemistry, organic synthesis, materi-als science. Although the direct transfer stereogenic group atom by N-alkylation one most efficient approaches to asymmetric C(sp3)–N bond formation, few methods are available enan-tioconvergent with racemic reagents. We report herein, previously unex-plored enantioconvergent...

Dysmenorrhea is a common gynecologic disorder in women of reproductive age. Previous studies have found an association between current cigarette smoking and prevalence dysmenorrhea. This study investigated the exposure to environmental tobacco smoke (ETS) occurrence dysmenorrhea among without history this disorder. The population consisted 165 newly wed, nonsmoking Chinese (in Shenyang, China), who intended get pregnant had no past at time enrollment. These completed baseline questionnaire...

A Gram-negative, aerobic, neutrophilic, moderately halophilic bacterial strain, HS225T, was isolated from seawater samples around the Zhoushan Archipelago, Zhejiang Province, China. The isolate grew optimally in media with 5.0 % NaCl, at pH 7.0–8.0 and 25–30 °C. predominant fatty acids were C16 : 0 ω9c, 0, C12 3-OH C18 1 ω9c. genomic DNA G+C content 59.0 mol%. Based on 16S rRNA gene sequence analysis, found to be affiliated genus Marinobacter. Strain HS225T exhibited closest phylogenetic...

Three Gram-negative, aerobic, motile, halophilic, rod-shaped strains (CN46(T), CN71 and CN74(T)) were isolated from sediment of the East China Sea subjected to a polyphasic taxonomic study. Strains CN46(T) had identical 16S rRNA gene sequences phenotypic characteristics. Strain was moderately halophilic. Growth strain observed between 0.5 10.0 % (w/v) NaCl (optimal growth at 3.0-5.0 %) pH 6.5 9.0. CN74(T) grew over wider range (pH 6.0-9.5); optimum concentration for 1.0-3.0 %. The major...

Human umbilical cord mesenchymal stem cells (hUC-MSCs) are potential stromal which regarded as the most feasible cell group in therapy. The maintenance of survival without differentiation is important transplantation and However, negative factors exist transplantation. Lysophosphatidic acid (LPA) a non-antigenic small molecule phospholipid induced several fundamental cellular responses, such proliferation, apoptosis migration. In this study we aimed to explore effects LPA on MSCs its...

The present study aimed to investigate whether genetic polymorphisms in the Toll-like receptor (TLR)-4 and Toll/interleukin-1 (TIR)-associated protein (TIRAP) genes, and/or their expression levels, influence susceptibility of a patient sepsis. A total 106 patients with sepsis were divided into two groups on basis acute physiology chronic health evaluation (APACHE) II scores: i) Sepsis group (APACHE <20) ii) B >20). In addition, 100 healthy volunteers enrolled control group. Polymerase chain...
