Deletions in mitochondrial DNA (mtDNA) accumulate with age in humans without overt mitochondriopathies, but relatively limited attention has been devoted to the measurement of the total number of mtDNA molecules per cell during ageing. We have developed a precise assay that determines mtDNA levels relative to nuclear DNA using a PCR-based procedure.(More)
To explore the relationship of gut microbiota with the development of type 2 diabetes (T2DM), we analyzed 121 subjects who were divided into 3 groups based on their glucose intolerance status: normal glucose tolerance (NGT; n = 44), prediabetes (Pre-DM; n = 64), or newly diagnosed T2DM (n = 13). Gut microbiota characterizations were determined with 16S(More)
BACKGROUND Remote perconditioning has been proved to reduce myocardial infarction and improve ventricular function in vivo. This study aims to determine the protection of remote perconditioning against cardiac reperfusion injury in patients undergoing valve replacement. METHODS Eighty-one patients admitted for selective valve replacement were divided into(More)
Brominated diphenly ether-209 (BDE-209, decaBDE) is among the most common flame retardants. In a previous study, it was confirmed that exposure to BDE-209 can decrease learning and memory in mice. However, it is still unknown whether BDE-209 has an effect on cultured neural stem cells (NSCs). To analyse the role of BDE-209 in the differentiation of neural(More)
Globally, brominated diphenyl ether-209 (BDE-209) is the most widely used polybrominated diphenyl ether (PBDEs). It has been reported that BDE-209 induces developmental neurotoxicity in vivo. The purpose of this study was to use an antioxidant, N-acetylcysteine (NAC), as an antidote for the neurotoxic effect of BDE-209. We used primary hippocampal neurons(More)
The congener brominated diphenyl ether- 209 (BDE-209) is a high-bromine polybrominated diphenyl ether (PBDE) and a common flame retardant that is applied to electronic equipment. In this study, we investigated the effects of BDE209 on the regulation of proliferation and apoptosis of neural stem cells (NSCs) and determined the underlying protein alterations.(More)
BACKGROUND Recent studies have identified signal transducer and activator of transcription 4 (STAT4) as a susceptibility gene for systemic lupus erythematosus (SLE) in different populations. In order to examine whether the allele distribution of the single nucleotide polymorphism (SNP) in gene STAT4 rs7574865 in patients with SLE is different from those of(More)
We report that humins extracted as the solid fractions from paddy soils or sediment are involved in extracellular electron transfer, coupled with microbial reductive dehalogenation of pentachlorophenol (PCP), by serving as both electron acceptor and electron donor. In our system, humin is requisite for the dechlorination of PCP, and this activity cannot be(More)
Age-related maculopathy susceptibility 2(ARMS2) was suggested to be associated with neovascular age-related macular degeneration (nAMD) and polypoidal choroidal vasculopathy (PCV) in multiple genetic studies in Caucasians and Japanese. To date, no biological properties have been attributed to the putative protein in nAMD and PCV. The complete genes of ARMS2(More)
To investigate the association of basal testosterone (T) levels with the outcome of in vitro fertilization (IVF) in women with diminished ovarian reserve (DOR). Complete clinical data on the first 223 IVF cycles in women with DOR were retrospectively analyzed. The associations of basal follicle stimulating hormone, luteinizing hormone, estradiol, and T(More)
