Sporadic heart failure is thought to have a genetic component, but the contributing genetic events are poorly defined. Here, we used ultra-high-throughput resequencing of pooled DNAs to identify SNPs in 4 biologically relevant cardiac signaling genes, and then examined the association between allelic variants and incidence of sporadic heart failure in 2(More)
It is shown in this paper that the nearly constant length-to-diameter ratio observed with conducting airways of human bronchial tree can be explained based on the fluid dynamic optimality principle. In any branched tube there are two pressure loss mechanisms, one for wall friction in the tube section and the other for flow division in the branching section,(More)
In the human bronchial tree the branching angle becomes larger with generation or for the smaller branches. Previous theories based on single parameter optimization have not been successful at all in predicting the consistent increasing trend of branching angle with continued bifurcation. In this study a new theory for the optimality of the branching angle(More)
Enterohemorrhagic Escherichia coli O157:H7 (EHEC) is a significant human pathogen that resides in healthy cattle. It is thought that a reduction in the prevalence and numbers of EHEC in cattle will reduce the load of EHEC entering the food chain. To this end, an intervention strategy involving the addition of chitosan microparticles (CM) to feed in order to(More)
Escherichia coli O157:H7 is a human pathogen capable of causing hemorrhagic colitis and in some cases hemolytic uremic syndrome. Cattle are an asymptomatic carrier and a major reservoir of this pathogen that can be transmitted by contaminated foods like beef products and vegetables. To further understand persistence in cattle and on farms, a total of 1716(More)
OBJECTIVES To examine the expression profile of Fas-Fas ligand (FasL) during glutamate (Glu)-induced spiral ganglion cell (SGC) apoptosis. METHODS Cultured SGCs were treated with 10-mM, 25-mM, and 50-mM concentrations of Glu and incubated for 24 or 48 hours. The expression intensity of FasL, Fas, caspase 3, and morphology of single SGC were evaluated(More)
Molecular imaging by two-photon microscopy (TPM) has become indispensable to the study of biology/medicine owing to its capability of imaging deep inside intact tissues. To make TPM a more-versatile tool, a large variety of two-photon probes are needed. Herein, we report a new two-photon fluorescent probe (ANi2) that can be excited by 750 nm femtosecond(More)
Raf kinase inhibitory protein (RKIP), an endogenous inhibitor of the extracellular signal-regulated kinase (ERK) pathway, has been implicated as a suppressor of metastasis and a prognostic marker in cancers. However, how RKIP acts as a suppressor during metastasis is not fully understood. Here, we show that RKIP activity in cervical and stomach cancer is(More)
We report a two-photon (TP) probe (ACaLN) for near-membrane Ca(2+) that shows a 13-fold TP excited fluorescence (TPEF) enhancement in response to Ca(2+), dissociation constants (K(d)(TP)) of (1.9±0.2) μM, pH-insensitivity at the biologically relevant pH, and can detect near-membrane Ca(2+) in live cells for more than 1500 s and in living tissues at 120 μm(More)
