Anion transport proteins in mammalian cells participate in a wide variety of cell and intracellular organelle functions, including regulation of electrical activity, pH, volume, and the transport of osmolites and metabolites, and may even play a role in the control of immunological responses, cell migration, cell proliferation, and differentiation. Although(More)
The complete genomic sequence of an aerobic thermoacidophilic crenarchaeon, Sulfolobus tokodaii strain7 which optimally grows at 80 degrees C, at low pH, and under aerobic conditions, has been determined by the whole genome shotgun method with slight modifications. The genomic size was 2,694,756 bp long and the G + C content was 32.8%. The following(More)
Although evidence of important contributions by Cl- channels to agonist-induced currents have been reported in vascular smooth muscle cells, the functional roles played by Cl- channels in the smooth muscle contraction and in setting the membrane potential remain essentially obscure. All of the admittedly few papers published have focused on the(More)
The complete sequence of the genome of a hyper-thermophilic archaebacterium, Pyrococcus horikoshii OT3, has been determined by assembling the sequences of the physical map-based contigs of fosmid clones and of long polymerase chain reaction (PCR) products which were used for gap-filling. The entire length of the genome was 1,738,505 bp. The authenticity of(More)
The complete sequence of the genome of an aerobic hyper-thermophilic crenarchaeon, Aeropyrum pernix K1, which optimally grows at 95 degrees C, has been determined by the whole genome shotgun method with some modifications. The entire length of the genome was 1,669,695 bp. The authenticity of the entire sequence was supported by restriction analysis of long(More)
Hydrogen sulfide (H₂S), a gasotransmitter, facilitates pain sensation by targeting Ca(v)3.2 T-type calcium channels. The H₂S/Ca(v)3.2 pathway appears to play a role in the maintenance of surgically evoked neuropathic pain. Given evidence that chemotherapy-induced neuropathic pain is blocked by ethosuximide, known to block T-type calcium channels, we(More)
We investigated the regulation of cardiac cystic fibrosis transmembrane conductance regulator (CFTR) Cl- channels by protein kinase C (PKC) in Xenopus oocytes injected with cRNA encoding the cardiac (exon 5-) CFTR Cl- channel isoform. Membrane currents were recorded using a two-electrode voltage clamp technique. Activators of PKC or a cAMP cocktail elicited(More)
We investigated whether Ba2+ and Sr2+ can substitute for Ca2+ in stimulating the nitric oxide (NO) production and cause relaxation in vascular smooth muscle. Ba2+ and Sr2+, like Ca2+, relaxed K(+)-depolarized canine coronary arteries in the presence of diltiazem. The Ba(2+)- and Sr(2+)-induced relaxation was endothelium-dependent and was largely inhibited(More)
BACKGROUND Anomalous origin of coronary artery (AOCA) has been described by coronary angiography or autopsy. However the actual prevalence of such abnormalities is unknown. Multi-detector computed tomography (MDCT) offers the possibility to visualize AOCA non-invasively. The purpose of this study was to report the prevalence AOCA by MDCT. METHODS AND(More)
