Background: Hemorrhagic fever with renal syndrome (HFRS) induced by Hantaan virus infection and heparin-induced thrombocytopenia (HIT) are associated with symptoms such as thrombocytopenia and thrombosis. However, related molecules, such as anti-platelet factor 4 (PF4)/heparin antibodies, in patients with HFRS have not been evaluated.

Objectives: To test plasma levels of anti-PF4/heparin antibodies and study the possible role of these antibodies in HFRS pathogenesis.

Objective: Gout is a chronic disease that causes inflammatory arthritis, which is closely related to urate accumulation induced by a disorder of uric acid metabolism and the consequent deposition of monosodium urate crystals. Rolfe is an herbal medicine that has been used in some traditional Chinese medicine formulae in the treatment of gout. This study aimed to explore and verify the antigout activity of extract (DLE) on alleviating the hyperuricaemia of mice and the acute gouty arthritis of rats.

A growing number of studies have suggested microRNAs (miRNAs) are involved in the modulation of myocardial ischemia-reperfusion (MI/R) injury; however, the role of endogenous miRNAs targeting endothelial cells (ECs) and its interaction with ICAM-1 in the setting of MI/R remain poorly understood. Our microarray results showed that miR-146a, miR-146b-5p, miR-155*, miR-155, miR-497, and miR-451 were significantly upregulated, whereas, miR-141 and miR-564 were significantly downregulated in the ECs challenged with TNF-α for 6 h. Real-time PCR analyses additionally validated that the expression levels of miR-146a, miR-155*, and miR-141 were consistent with the microarray results.

Oleuropein (OE), the main polyphenol in olive leaf extract, is likely to decompose into hydroxytyrosol (HT) and elenolic acid under the action of light, acid, base, high temperature. In the enzymatic process, the content of OE in olive leaf extract and enzyme are key factors that affect the yield of HT. A selective enzyme was screened from among 10 enzymes with a high OE degradation rate.

The use of endosseous implanted materials is often limited by undesirable effects that may be due to macrophage-related inflammation. The purpose of this study was to fabricate a nanostructured surface on a titanium implant to regulate the macrophage inflammatory response and improve the performance of the implant. Anodization at 5 and 20 V as well as UV irradiation were used to generate hydrophilic, nanostructured TiO2 surfaces (denoted as NT5 and NT20, respectively).

Background: Hantaan virus (HTNV) could cause a severe lethal hemorrhagic fever with renal syndrome (HFRS) in humans. Despite a limited understanding of the pathogenesis of HFRS, the importance of host-related immune responses in the pathogenesis of HFRS has been widely recognized. CD100/Sema4D has been demonstrated to play an important role in physiological and pathological immune responses, but the functional role of CD100 in infectious diseases has only been inadequately reported.
