BACKGROUND Hydrogen has been reported to selectively reduce hydroxyl radicals and peroxynitrite anion in many pathologic processes. This study aimed to test the hypothesis that hydrogen-rich saline (HRS) may ameliorate organ dysfunction in a rat model of polymicrobial sepsis. METHODS Sepsis was induced in male Sprague-Dawley rats by cecal ligation and(More)
The receptor for hyaluronan-mediated motility (RHAMM), an acidic coiled coil protein, has previously been characterized as a cell surface receptor for hyaluronan, and a microtubule-associated intracellular hyaluronan binding protein. In this study, we demonstrate that a subset of cellular RHAMM localizes to the centrosome and functions in the maintenance of(More)
Synaptic connections of neurons in the Drosophila lamina, the most peripheral synaptic region of the visual system, have been comprehensively described. Although the lamina has been used extensively as a model for the development and plasticity of synaptic connections, the neurotransmitters in these circuits are still poorly known. Thus, to unravel possible(More)
A real-time cell electronic sensing (RT-CES) system was used for label-free, dynamic measurement of cell responses to cytotoxicants. Cells were grown onto the surfaces of microelectronic sensors, which are comprised of circle-on-line electrode arrays and are integrated into the bottom surfaces of the microtiter plate. Changes in cell status such as cell(More)
Molecular hydrogen (H2) metabolism in bacteria and algae has been well studied from an industrial perspective because H2 is viewed as a potential future energy source. A number of clinical trials have recently reported that H2 is a therapeutic antioxidant and signaling molecule. Although H2 metabolism in higher plants was reported in some early studies, its(More)
Inflammatory leukocytes infiltrate the CNS parenchyma in neuroinflammation. This involves cellular migration across various structures associated with the blood-brain barrier: the vascular endothelium, the glia limitans, and the perivascular space between them. Leukocytes accumulate spontaneously in the perivascular space in brains of transgenic (Tg) mice(More)
The number and morphology of mitochondria within a cell are precisely regulated by the mitochondrial fission and fusion machinery. The human protein, hFis1, participates in mitochondrial fission by recruiting the Drp1 into the mitochondria. Using short hairpin RNA, we reduced the expression levels of hFis1 in mammalian cells. Cells lacking hFis1 showed(More)
This study is to examine if hydrogen-rich saline reduced amyloid-beta (Aβ) induced neural inflammation and oxidative stress in a rat model by attenuation of activation of JNK and NF-κB. Sprague-Dawley male rats (n=18, 280-330 g) were divided into three groups, sham operated, Aβ1-42 injected and Aβ1-42 plus hydrogen-rich saline treated animals. Hydrogen-rich(More)
The mitotic checkpoint is an essential surveillance mechanism that ensures high fidelity chromosome segregation during mitosis. Mitotic checkpoint function depends on numerous kinetochore proteins, including ZW10, ROD, and Zwilch (the ROD-ZW10-Zwilch complex). Through an extensive mutagenesis screen of hZW10, we have mapped the kinetochore localization(More)
BACKGROUND Recently it has been demonstrated that hydrogen, as a novel antioxidant, can selectively reduce hydroxyl radicals (·OH) and peroxynitrite anion (ONOO-) in vitro and exert therapeutic antioxidant activity in many diseases. This study was designed to investigate the effect of hydrogen-rich saline on renal ischemia/reperfusion (I/R) injury in rats.(More)
