Excitation-contraction coupling in skeletal muscle involves a voltage sensor in the plasma membrane which, in response to depolarization, causes an intracellular calcium-release channel to open. The skeletal isoform of the ryanodine receptor (RyR-1) functions as the Ca2+-release channel and the dihydropyridine receptor (DHPR) functions as the voltage sensor(More)
To evaluate the effects of transgenic expression of Coleopteran-specific Bt protein Cry3Bb1 on target and nontarget insects in fields with Bt crops, it is necessary to quantify the Cry3Bb1 contents in the plants. Here, we describe the optimization and validation of the quantitative detection of Cry3Bb1 by adapting the commercially available qualitative(More)
BACKGROUND Inflammatory bowel diseases (IBD), including mainly ulcerative colitis (UC) and Crohn's disease (CD), are inflammatory disorders of the gastrointestinal tract caused by an interplay of genetic and environmental factors. Murine colitis model induced by Dextran Sulfate Sodium (DSS) is an animal model of IBD that is commonly used to address the(More)
Nam Dinh province in Red River Delta, Vietnam, is an endemic area for the human liver fluke Clonorchis sinensis, but little is known about its occurrence in the fish intermediate host in this region. A cross-sectional study was carried out to identify fish-borne zoonotic trematodes (FZT) species diversity and to estimate the prevalence and infection(More)
The attaching and effacing (A/E) pathogen enteropathogenic Escherichia coli (EPEC) forms characteristic actin-filled membranous protrusions upon infection of host cells termed pedestals. Here we examine the role of the RNA binding protein CsrA in the expression of virulence genes and proteins that are necessary for pedestal formation. The csrA mutant was(More)
In contrast with the Parkinson's-like effects associated with the mitochondrial neurotoxin N-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) and the neuroleptic agent haloperidol, there exist no reports on adverse central nervous system (CNS) effects with the structurally related N-substituted-4-arylpiperidin-4-ol derivative and antidiarrheal agent(More)
The transmembrane glycoprotein CD98 regulates multiple cellular functions, including extracellular signaling, epithelial cell adhesion/polarity, amino acid transport, and cell-cell interactions. MicroRNAs post-transcriptionally regulate gene expression, thereby functioning as modulators of numerous cellular processes, such as cell differentiation,(More)
Diminished expression of TCR zeta and reciprocal up-regulation and association of FcRgamma with the TCR/CD3 complex is a hallmark of systemic lupus erythematosus (SLE) T cells. In this study we explored whether differential molecular associations of the spleen tyrosine kinase Syk that preferentially binds to FcRgamma contribute to pathological amplification(More)
Mousepox was identified in a single mouse-holding room in early 1999 after a group of 20 CAF1/Hsd mice were inoculated SC with a killed murine spindle cell tumor line, S1509A. The cell line had been used without complications multiple times and was determined to be free of viral contamination on the basis of results of mouse antibody production testing. Of(More)
