AIMS: C1q/TNF-related protein-9 (CTRP9) is a novel adipokine that has been shown to promote lipid metabolism, enhance insulin sensitivity and protect against cardiovascular disease. However, previous studies in humans have produced controversial results regarding the association between CTRP9 and insulin resistance. The objective of this study was to evaluate the relationships between CTRP9 and insulin resistance in Chinese population. METHODS: Subjects with normal glucose tolerance (NGT, n=108), impaired glucose tolerance (IGT, n=92), and newly diagnosed type 2 diabetes mellitus (nT2DM, n=106) were recruited to determining the circulating CTRP9 and adiponectin levels by enzyme linked immunosorbent assay...

Closed head injury (CHI) usually results in severe and permanent neurological impairments, which are caused by several intertwined phenomena, such as cerebral edema, blood-brain barrier (BBB) disruption, neuronal loss, astroglial scarring and inflammation. We previously reported that induced neural stem cells (iNSCs), similar to neural stem cells (NSCs), can accelerate neurological recovery in vivo and produce neurotrophic factors in vitro. However, the effects of iNSC neurotrophy following CHI were not determined...

Prenatal exposure to organophosphorus pesticides (OPs) has been associated with different neurodevelopmental outcomes across different cohorts. A phenotypic approach may address some of these differences by incorporating information across scales and accounting for the complex correlational structure of neurodevelopmental outcomes. Additionally, Bayesian hierarchical modeling can account for confounding by collinear co-exposures. We use this framework to examine associations between prenatal exposure to OPs and behavior, executive functioning, and IQ assessed at age 6-9 years in a cohort of 404 mother/infant pairs recruited during pregnancy...

Vertebrate centromeres are epigenetically defined by nucleosomes containing the histone H3 variant, CENP-A. CENP-A nucleosome assembly requires the three-protein Mis18 complex (Mis18α, Mis18β, and M18BP1) that recruits the CENP-A chaperone HJURP to centromeres, but how the Mis18 complex recognizes centromeric chromatin is unknown. Using Xenopus egg extract, we show that direct, cell-cycle-regulated binding of M18BP1 to CENP-A nucleosomes recruits the Mis18 complex to interphase centromeres to promote new CENP-A nucleosome assembly...

Access to safe, off-farm childcare is often a challenge for farmworkers with young children and is likely to become an increasingly salient barrier as more agricultural workers migrate together with families and as the number of women entering the agricultural workforce increases. Agriculture is one of the most hazardous industries, and the presence of young children in the workplace puts them at risk. To better understand the current nature of childcare for farmworker families and the challenges to accessing services, this project facilitated in-person surveys with 132 parents in three communities in Florida...

BACKGROUND AND OBJECTIVES: Large-scale application of Quantitative Sensory Tests (QST) is impaired by lacking standardized testing protocols. One unclear methodological aspect is the number of records needed to minimize measurement error. Traditionally, measurements are repeated 3 to 5 times, and their mean value is considered. When transferring QST to a clinical setting, reducing the number of records would be desirable to meet the time constraints encountered in a routine clinical environment and to reduce the testing burden to chronic pain patients...

The major histocompatibility complex class I-related chain A (MICA), expressed on cell surface, plays an important role in the elimination of both virus-infected cells and tumor through the activation of the natural killer (NK) receptor NKG2D. A polymorphic change from methionine (Met) to valine (Val) at amino acid position 129 categorizes MICA alleles into strong and weak binders for the NKG2D receptor and has been found in a variety of immune-related disorders. In this study, we investigated the potential interaction between genetic polymorphism of MICA and the development of breast cancer...

The incidence of Helicobacter pylori (H. pylori) infection and gastric cancer is on the rise in India, and the genetic factors influencing the increased susceptibility in Indian population remain obscure. Toll-like receptors (TLRs) play a major role in innate immune system and genetic polymorphisms affecting their function were reported to enhance the risk for H. pylori infection. Seventy-seven patients (n = 77) diagnosed with H. pylori infection and 230 healthy subjects were recruited in this study. The rs2072493, rs5744174, and rs5744168 polymorphisms within TLR5 gene were genotyped using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and Tetra-ARMS PCR genotyping techniques...
