Growth, mortality, and resource utilization of in Langcuo Lake of Tibetan Plateau, China.

To investigate the growth, mortality, and resource utilization of in Langcuo Lake of Tibetan Plateau, we measured body length and body weight of 389 fish based on four sampling surveys from October 2018 to November 2019. We identified the ages through lapillus. Based on frequency distribution of body length, we estimated the growth and mortality coefficients of .

Selection of suitable reference genes for quantitative real time PCR in different Tulasnella isolates and orchid-fungus symbiotic germination system.

Under natural conditions, mycorrhizal symbiosis accompanies nearly the entire life cycle of orchids from seed germination through to flowering and fruiting. Tulasnella-like orchid mycorrhizal fungi are the most common mycorrhizal fungi found in association with orchid species. Presently suitable reference genes have not been systematically selected for the quantification of gene expression via Real-Time Quantitative Reverse Transcription PCR (RT-qPCR).

Arthrobacter crusticola sp. nov., Isolated from Biological Soil Crusts in the Mu Us Sandy Land, China.

Mu Us Sandy Land in China is a very fragile ecological environment due to serious desertification. While attempting to gain insights into the biodiversity of biological soil crusts of Mu Us Sandy Land, a novel bacterial strain, SLN-3, was isolated. It was phylogenetically placed into the genus Arthrobacter within the family Micrococcaceae based on its 16S rRNA gene sequence.

A gram-stain-negative, aerobic, non-spore-forming, rod-shaped, non-motile bacterium strain R4HLG17 was isolated from Tamarix ramosissima roots growing in Kumtag desert. The strain grew at salinities of 0-16% (w/v) NaCl (optimum 5-6%), pH 5-9 (optimum 7) and at 16-45 °C. Based on 16S rRNA gene sequence similarity, strain R4HLG17 belonged to the family Halomonadaceae and was most closely related to Halomonas lutea DSM 23508(95.

Flexible Carbon Nanotube-Based Polymer Electrode for Long-Term Electrocardiographic Recording.

The long-term monitoring of electrocardiogram (ECG) is critical for the accurate diagnosis and tracking of cardiovascular diseases (CVDs). However, the commercial Ag/AgCl electrode is not suitable for long-term monitoring due to skin allergies and signal degradation, caused by the conductive gel drying over time. In this paper, a flexible gel-free electrode, composed of a multi-wall carbon nanotube (MWCNT) and polydimethylsiloxane (PDMS), is proposed for long-term wearable ECG monitoring.

Perfluoroalkane sulfonyl fluorides non-covalently bind to human serum albumin at Sudlow's sites.

Perfluorooctane sulfonyl fluoride (PFOSF) has been defined as persistent organic pollutant in the Stockholm Convention in 2009. Currently PFOSF and its substitutes (structural analogues in which octyl group is substituted for other aliphatic chains) are still scarcely studied. HSA is a main carrier for drugs in blood, and the influence of exogenous compounds including pollutants on HSA is of particular interest.

A brief review: the therapeutic potential of bone marrow mesenchymal stem cells in myocardial infarction.

Myocardial infarction (MI) results in dysfunction and irreversible loss of cardiomyocytes and is among the most serious health threats today. Bone marrow mesenchymal stem cells (BMSCs), with their capacity for multidirectional differentiation, low immunogenicity, and high portability, can serve as ideal seed cells in cardiovascular disease therapy. In this review, we examine recent literature concerning the application of BMSCs for the treatment of MI and consider the following aspects: activity of transplanted cells, migration and homing of BMSCs, immunomodulatory and anti-inflammatory effects of BMSCs, anti-fibrotic activity of BMSCs, the role of BMSCs in angiogenesis, and differentiation of BMSCs into cardiomyocyte-like cells and endothelial cells.

Development of a diagnosis model for coronary artery disease.

Background: The purpose of this study was to develop a coronary artery disease (CAD) prediction model that optimally estimates the pre-test probability of CAD for patients suspected of CAD.

Methods And Results: This retrospective, multi-centre study included 7360 consecutive patients (4678 men, 57.87±11.

ABCB1 C3435T polymorphism and the risk of ischemic heart disease: a meta-analysis.

ATP binding cassette transporter 1 (ABCB1) plays a critical role in the development and progression of cardiovascular disease. Emerging evidence suggests that common functional polymorphisms in the ABCB1 gene might have an impact on an individual's susceptibility to ischemic heart disease, but individually published results are inconclusive. The MEDLINE (1966-2013), the Cochrane Library Database (Issue 12, 2013), EMBASE (1980-2013), CINAHL (1982-2013), Web of Science (1945-2013), and the Chinese Biomedical Database (CBM; 1982-2013) were searched without language restrictions.

Seven functional polymorphisms in the CETP gene and myocardial infarction risk: a meta-analysis and meta-regression.

Objective: This meta-analysis aims to evaluate the relationships between seven functional polymorphisms in the CETP gene and myocardial infarction (MI) risk.

Method: The PubMed, CISCOM, CINAHL, Web of Science, Google Scholar, EBSCO, Cochrane Library, and CBM databases were searched for relevant articles published before March 1st, 2013 without any language restrictions. Meta-analysis was conducted using the STATA 12.

SELP genetic polymorphisms may contribute to the pathogenesis of coronary heart disease and myocardial infarction: a meta-analysis.

We conducted a meta-analysis of case-control studies to determine whether SELP genetic polymorphisms contribute to the pathogenesis of coronary heart disease (CHD) and myocardial infarction (MI). A range of electronic databases were searched: MEDLINE (1966-2013), the Cochrane Library Database (Issue 12, 2013), EMBASE (1980-2013), CINAHL (1982-2013), Web of Science (1945-2013) and the Chinese biomedical database (1982-2013) without language restrictions. Meta-analysis was performed with the use of the STATA statistical software.

ALDH2 rs671 Polymorphism and coronary heart disease risk among Asian populations: a meta-analysis and meta-regression.

Mitochondrial aldehyde dehydrogenase-2 (ALDH2) is the principal enzyme involved in alcohol metabolism in humans. Emerging evidence has shown that the common rs671 G>A (Glu504Lys) polymorphism in the ALDH2 gene might play a critical role in increasing the susceptibility to coronary heart disease (CHD), including myocardial infarction (MI); however, individually published studies showed inconclusive results. This meta-analysis aimed to derive a more precise estimation of the relationship between the ALDH2 rs671 polymorphism and its influence on the susceptibility to CHD and MI.

The antinociceptive efficacy of HWTX-I epidurally administered in rheumatoid arthritis rats.

Rheumatoid arthritis (RA) is one of the inflammatory kinds of arthritis in the clinical situation, and cytosolic Ca2+ overload has been proposed as one of the primary factors for many inflammatory cells activation, which lead to relative enzymes and inflammatory factors release. It is therefore accepted that Ca2+ channel blockers can protect joint injury from inflammation. In the present study we investigated the possible molecular mechanism of the antinociceptive efficacy of HWTX-I, a spider peptide toxin blocking Ca2+ channels, on the rat rheumatoid arthritis model.
