Staphylococcal enterotoxin B exposed to pregnant rats inhibits the hedgehog signaling pathway in thymic T lymphocytes of the offspring.

The Hedgehog (Hh) signaling pathway is involved in T cell differentiation and development and plays a major regulatory part in different stages of T cell development. A previous study by us suggested that prenatal exposure to staphylococcal enterotoxin B (SEB) changed the percentages of T cell subpopulation in the offspring thymus. However, it is unclear whether prenatal SEB exposure impacts the Hh signaling pathway in thymic T cells.

A randomized controlled trial investigating the impact of a single flash cupping session on patients with chronic lower back pain using multichannel surface electromyographic assessment.

Background: Chronic lower back pain (CLBP) is one of the most common disorders worldwide. Flash cupping has the ability to relieve CLBP; nevertheless, its impact on CLBP and the likely mechanism of action have not been studied.

Objective: The goal of this study was to assess the impact of a single, brief cupping session on CLBP and low back muscle activity using multichannel surface electromyography (sEMG).

Resonance assignments of the cytoplasmic domain of ECF sigma factor W pathway protein YsdB from Bacillus subtilis.

Bacterial sigma (σ) factor, along with RNA polymerase core enzyme, initiates gene transcription from specific promoter regions and therefore regulates clusters of genes in response to a particular situation. The extracytoplasmic function (ECF) σ factors are a class of alternative σ factors that are often associated with environmental signal transduction across the bacterial membrane, in which external signal triggers the release of active σ from the membrane-anchored anti-σ factor. Gram-positive model organism Bacillus subtilis (B.

Characterization of the complete chloroplast genome of (Apocynaceae: Asclepiadoideae: Asclepiadeae), a rare and threatened liana endemic to China.

The complete chloroplast genome of , a rare liana of the Asclepiadoideae endemic to China, was determined in this study. It is classified as Vulnerable species because of the sharp decline in its population size due to the habitat destruction. The whole chloroplast genome was 160,308 bp long, comprising of a large single copy (LSC) region of 91,335 bp and a small single copy (SSC) region of 19,185 bp, which were separated by a pair of 24,894 bp long inverted repeat (IR) regions.

Structure elucidation and antioxidant activity of a novel polysaccharide from Polyporus umbellatus sclerotia.

A novel water-soluble polysaccharide PUP60S2, with a molecular weight of 1.44×10(4)Da, was obtained from the sclerotia of Polyporus umbellatus by hot water extraction, ethanol precipitation, anion-exchange and size-exclusion chromatography. PUP60S2 was a polysaccharide comprised of about 22.

C2 nerve dysfunction associated with C1 lateral mass screw fixation.

The C1 lateral mass screw technique is widely used for atlantoaxial fixation. However, C2 nerve dysfunction may occur as a complication of this procedure, compromising the quality of life of affected patients. This is a review of the topic of C2 nerve dysfunction associated with C1 lateral mass screw fixation and related research developments.

[Evolution of miRNA in plants].

Due to the important role of miRNA in regulation of plant gene expression, researchers have focused on the prediction, identification, functional and evolutionary analysis of miRNA. As genome sequencing has been completed in many species, the integration of genomic sequences with evolutionary data of miRNA provides more and more evidence and hypotheses for the origin and evolution of miRNA. However, the evolution of miRNA in plants has not been extensively reviewed.

Incidence and mortality of breast cancer in China, 2008.

Background: Female breast cancer incidence and mortality data for the duration of 2008, in China, retrieved from the National Central Cancer Registry, was analyzed.

Methods: In 2008, there were 56 registries that submitted cancer registration data. Based on the criteria of data quality, a total of 41 registries' data met the requirement and were accepted for analysis.

Report of incidence and mortality in china cancer registries, 2008.

Objective: Annual cancer incidence and mortality in 2008 were provided by National Central Cancer Registry in China, which data were collected from population-based cancer registries in 2011.

Methods: There were 56 registries submitted their data in 2008. After checking and evaluating the data quality, total 41 registries' data were accepted and pooled for analysis.

[Ovary cancer mortality in China 2004 - 2005: results from the Third National Retrospective Sampling Survey of Death Causes].

Objective: To analyze the distribution characteristics and trend of ovary cancer mortality based on results of the Third National Retrospective Sampling Survey of Death Causes.

Methods: Data of National Retrospective Sampling Survey for the years of 2004 - 2005 from 158 counties/cities/districts was used for the settings. A total of 69,690,241 person-year for female between 2004 and 2005 including 23,598,822 person-year in urban and 46,091,419 person-year in rural were respectively included in the study.

[Geographical distribution of cancer mortality in China, 2004-2005].

Objective: To describe geographical distribution and its transition of mortality of cancers in China.

Methods: The information of 2 513 949 310 person years were collected in 1973-1975 and 142 660 482 person years in 2004-2005 respectively. Being standardizing the death rates of these two survey with 2000 national census population, the changes of mortality of main cancers was observed and the geographic distribution of cancers in 2004-2005 was analyzed.

Representativeness of population-based cancer registration in China--comparison of urban and rural areas.

Objective: Chinese cancer registration data provide information on the national cancer burden but how representative they are of the real situation is uncertain. Mortality data from cancer registration and the third national death survey were therefore compared to determine the accuracy of estimates in China.

Methods: The data were from the Cancer Registration Annual Report, 2004, China and the third National Death Survey, 2004-205.
