View Article and Find Full Text PDFDNA methylation is one of the earliest discovered and most extensively studied epigenetic regulatory mechanisms. Broadly, DNA methylation refers to the transfer of a methyl group on S‑adenosine‑L‑methionine (SAM) to the C5 site of cytosine, a reaction catalysed by DNA methyltransferase (DNMT). This process can either up‑ or down‑regulate gene expression due to gene promoter methylation, leading to the occurrence of certain diseases.

However, the mechanism of its protective effect against ototoxicity is not well understood. In this study, we used in vitro and in vivo methods to investigate the protective mechanism of puerarin against cisplatin (CDDP)-induced ototoxicity.

This paper proposes interesting aspects of the unique feature of the SCS waves in response to tropical cyclone's passage when large-scale winter monsoon winds prevail. We use the wave model WaveWatch III to study the wave characteristics of typhoon Durian (2006) passing over the middle of SCS in early December 2006, and state the new understanding acquired in the aspects of the tropical cyclone generated waves in the SCS during winter monsoon surge.

Pulmonary vascular remodeling is the most important pathological characteristic of pulmonary arterial hypertension (PAH). No effective treatment for PAH is currently available because the mechanism underlying vascular remodeling is not completely clear. CD248, also known as endosialin, is a transmembrane protein that is highly expressed in pericytes and fibroblasts.

However, ototoxicity is a major side effect of CDDP, and there is an associated risk of irreversible hearing loss. We previously demonstrated that CDDP could induce ototoxicity via activation of the transient receptor potential vanilloid receptor 1 (TRPV1) pathway and subsequent induction of oxidative stress.

Methods: Rats were divided into five groups, with 10 animals in each group.
MiR-328-3p has been reported to be downregulated and serve as a tumor suppressor in several cancers. Previous studies only have reported the downregulation of miR-328-3p in CRC. However, the roles of miR-328-3p in CRC growth and metastasis were unknown.

However, the effects of miR-346-5p on CRC progression have not yet been clarified. In our study, miR-346-5p levels in four CRC cell lines and normal human colon epithelial cells were determined by real-time PCR.

The study aimed to describe the probable usefulness of the MEWS in identifying deteriorating post-Whipple patients in hospital wards.
Methods: We performed a study to analyze the relationship between the vital parameters and postoperative severe adverse events of patients after Whipple surgery in Guangdong Provincial People's Hospital from 2000 to 2017.

Fresh onions ( L.) emit volatile organic compounds (VOCs) naturally in very low concentrations. The aim of the present study was to determine the emission rate of low-boiling VOCs from healthy and naturally infected onion bulbs at 4, 15, and 25 °C and to evaluate the applicability of the VOC method to monitor quality changes during 12 weeks of storage of two cultivars ('Hystand' and 'Hoza') of yellow onions.

Impairment of insulin vascular action may represent a mechanism linking insulin resistance and CVDs. The present study tested the hypothesis that adipocyte-derived resistin inhibits insulin-stimulated endothelial NO production through the induction of ER stress.

The seasonal variation, inter-decadal variation, long-term trend and the tide-surge interaction were analyzed separately. The results show that the storm surges in the southwest Bohai Sea are larger than those in the north.

Ischemia/reperfusion (I/R) is a major cause of acute kidney injury (AKI), along with delayed graft function, which can trigger chronic kidney injury by stimulating epithelial to mesenchymal transition (EMT) in the kidney canaliculus. Sphingosine 1-phosphate receptor 1 (S1P1) is a G protein-coupled receptor that is indispensable for vessel homeostasis. This study aimed to investigate the influence of S1P1 on the mechanisms underlying I/R-induced EMT in the kidney using in vivo and in vitro models.
