The transient receptor potential vallinoid type 4 (TRPV4) channel has been implicated in the endothelial shear response and flow-mediated dilation, although the precise functions of this channel remain poorly understood. In the present study, we investigated the role of TRPV4 in shear stress-induced endothelial Ca(2+) entry and the potential link between(More)
BACKGROUND Arachidonic acid (AA) and/or its enzymatic metabolites are important lipid mediators contributing to endothelium-derived hyperpolarizing factor (EDHF)-mediated dilation in multiple vascular beds, including human coronary arterioles (HCAs). However, the mechanisms of action of these lipid mediators in endothelial cells (ECs) remain incompletely(More)
This work aimed to validate the approach of using a circle to fit the toe trajectory relative to the hip and to investigate linear regression models for describing such toe trajectories from normal gait. Twenty-four subjects walked at seven speeds. Best-fit circle algorithms were developed to approximate the relative toe trajectory using a circle. It was(More)
Generating a natural foot trajectory is an important objective in robotic systems for rehabilitation of walking. Human walking has pendular properties, so the pendulum model of walking has been used in bipedal robots which produce rhythmic gait patterns. Whether natural foot trajectories can be produced by the pendulum model needs to be addressed as a first(More)
Angiopoietin-like protein 8 (ANGPTL8)/betatrophin, a newly identified protein, is primarily expressed in the liver and regulates the glucose metabolic transition during fasting and re-feeding in mice with or without insulin resistance. These findings strongly suggest that ANGPTL8/betatrophin could be a novel glucose-lowering candidate medicine for type 2(More)
Emerging evidence suggests that Nanog is involved in cervical tumorigenesis. However, the regulating role of Nanog in tumorigenesis and chemosensitivity are still poorly understood. In this study, Nanog was disrupted by transcription activator-like effector nucleases (TALEN) in Hela cells and its expression was significantly decreased in a single-cell(More)
There is biological evidence that the brain opioidergic system plays a critical role in the addictive properties of nicotine. The purpose of the present study was to examine the associations of single nucleotide polymorphisms (SNPs) in the genes encoding mu-opioid receptor (MOR) and the MOR-interacting proteins (including OPRM1, ARRB2, and HINT1) with(More)
Diabetic cardiomyopathy increases the risk of heart failure and death. At present, there are no effective approaches to preventing its development in the clinic. Here we report that reduction of cardiac GTP cyclohydrolase 1 (GCH1) degradation by genetic and pharmacological approaches protects the heart against diabetic cardiomyopathy. Diabetic(More)
A macro-micro-nano-multi-level study was conducted to explore age-related structural and mechanical properties of bone, as well as the effects of aging on bone properties. A total of 70 male Wistar rats were used, ranging in the ages of 1, 3, 5, 7, 9, 11, 14, 15, 16, and 17 months (n = 7/age group). After micro-computed tomography (CT) scanning,(More)
The purpose of this systematic review was to evaluate the predictive validity of the Identification of Seniors at Risk (ISAR) Tool in identifying elderly patients at risk of adverse outcomes after a visit to the emergency department (ED). Since older adults are frequently sent to the ED, screening for risk of adverse outcomes in elderly patients is(More)
