Activation of the cardiac ryanodine receptor (RyR2) by Ca(2)+ is an essential step in excitation-contraction coupling in heart muscle. However, little is known about the molecular basis of activation of RyR2 by Ca(2)+. In this study, we investigated the role in Ca(2)+ sensing of the conserved glutamate 3987 located in the predicted transmembrane segment M2(More)
BACKGROUND Poor physician handoff can be a major contributor to suboptimal care and medical errors occurring in the hospital. Physician handoffs for intensive care unit (ICU)-to-ward patient transfer may face more communication hurdles. However, few studies have focused on physician handoffs in patient transfers from the ICU to the inpatient ward. METHODS(More)
Forests play a leading role in regional and global carbon (C) cycles. Detailed assessment of the temporal and spatial changes in C sinks/sources of China’s forests is critical to the estimation of the national C budget and can help to constitute sustainable forest management policies for climate change. In this study, we explored the spatio-temporal changes(More)
The aim of this study was to investigate incidence trend of childhood type 1 diabetes in Shanghai, a megalopolis in east China. We established a population-based retrospective registry for the disease in the city’s registered population during 1997–2011 and collected 622 incident type 1 diabetes in children aged 0–14 years. Standardized incidence rates and(More)
In the setting of central precocious puberty (CPP), the motivation for hormonal intervention is to help the child to reach a taller adult stature than she would achieve otherwise. While gonadotropin-releasing hormone analogs (GnRHa) constitute an established treatment for improving adult stature in girls presenting with CPP up to age 6 (true precocious(More)
OBJECTIVE The kisspeptin/GPR54 pathway has been proven to be crucial in the process of puberty onset, yet the polymorphisms in the KISS1 gene and their relationships with central precocious puberty (CPP) have not been investigated. This study was performed to reveal the relationship between the gene and the disease. DESIGN AND METHODS 272 Chinese Han(More)
IL-33 is a new member of the IL-1 family that plays a role in inflammation. In this study, we evaluated the potential of IL-33 inhibition as a treatment for systemic lupus erythematosus (SLE) using the lupus-prone model MRL/lpr mice and the underlying mechanisms of action. We treated mice with anti-mouse IL-33 antibody (anti-IL-33Ab) via intraperitoneal(More)
Long noncoding RNAs play a vital role in diverse biological processes such as embryonic development, cell growth, and tumorigenesis. In this study, we report that LncRNA ANRIL, which encodes a 3834-nt RNA that contains 19 exons at the antisense orientation of the INK4B-ARF-INK4A gene cluster, generally up-regulated in nasopharyngeal carcinoma [1]. In a(More)
Biomass carbon accumulation in forest ecosystems is a widespread phenomenon at both regional and global scales. However, as coupled carbon-climate models predicted, a positive feedback could be triggered if accelerated soil carbon decomposition offsets enhanced vegetation growth under a warming climate. It is thus crucial to reveal whether and how soil(More)
Exosomes are one type of membrane vesicles secreted into extracellular space by most types of cells. In addition to performing many biological functions particularly in cell-cell communication, cumulative evidence has suggested that several biological entities in exosomes like proteins and microRNAs are closely associated with the pathogenesis of most human(More)
