Relationship between CaSRs and LPS-injured cardiomyocytes.

Objective: Calcium-sensing receptors (CaSRs) regulate systemic calcium homeostasis. Intracellular calcium concentration changes are initiating factors of endoplasmic reticulum stress and cell autophagy. Recent research has revealed that CaSRs play an important role in myocardial ischemia/reperfusion injury and other cardiovascular diseases.

Recombinant expressed vasoactive intestinal peptide analogue ameliorates TNBS-induced colitis in rats.

Aim: To investigate the modulatory effect of recombinant-expressed vasoactive intestinal peptide (VIP) analogue (rVIPa) on trinitrobenzene sulfonic acid (TNBS)-induced colitis in rats.

Methods: Forty-eight rats were randomized into six groups: normal control group (Control), model control group (TNBS), ethanol treatment group (ETOH), and VIP treatment groups with different dosage (rVIPa, rVIPa, rVIPa). Diarrhea and bloody stool were observed.

Screening of different sample types associated with sheep and cattle for the presence of nematophagous fungi in China.

A total of 1502 samples, including feces of sheep (793) and cattle (348), pasture soil (118), dung compost (147) and barn soil (96), were examined between October 2012 and August 2014 to discover potential strains of nematophagous fungi for the biological control of livestock-parasitic nematodes. These samples were collected from 87 sites located in 48 counties of 20 provinces (autonomous regions/municipalities) of China. Fungi were identified down to a species level.

[Developmental status and prospect of musical electroacupuncture].

Through searching domestic and foreign medical journals in CNKI, Wanfang database, VIP database and Pubmed database from January of 2003 to November of 2013, 39 articles regarding musical electroacupuncture (MEA) were analyzed. The result showed that MEA was clinically used to treat neurological and psychotic disorders; because it was combined with musical therapy and overcame the acupuncture tolerability, and MEA was superior to traditional electroacupuncture. However, problems such as low research efficiency and the mechanism of MEA superiority and the musical specificity not being revealed by research design still exist.

Isolation, identification, and characterization of the nematophagous fungus Monacrosporium salinum from China.

Nematophagous fungi are considered to have the best potential as biological agents for the control of gastrointestinal nematodes in domestic animals. However, relatively few studies have been conducted with the genus Monacrosporium, especially with strains native to China. In the present study, we isolated and identified nematophagous fungi from fresh sheep feces.

Protective effect of glutamine on intestinal injury and bacterial community in rats exposed to hypobaric hypoxia environment.

Aim: To investigate the protective effect of glutamine (Gln) on intestinal injury and the bacterial community in rats exposed to hypobaric hypoxia environment.

Methods: Sprague-Dawley rats were divided into control, hypobaric hypoxia (HH), and hypobaric hypoxia + Gln (5.0 g/kg BW·d) (HG) groups.

[Development of cell-penetrating peptides as vectors for drug delivery].

Biomacromolecules play an important role in the treatment of many diseases, but as a result of cell membrane serving as the natural barriers, only the small molecular compounds whose molecular weights are smaller than 600 Da can get through cell membrane and enter the cell. In recent years, some short peptides (the length less than 30 amino acids) are found to have the cell-penetrating function, called cell-penetrating peptides (CPPs). They are able to effectively translocate segments of protein, polypeptides, nucleic acid into the cells of many mammal animals with many methods.
