Although Candida rugosa utilizes a nonuniversal serine codon (CUG) for leucine, it is possible to express lipase genes (LIP) in heterologous systems. After replacing the 19 CUG codons in LIP4 with serine codons by site-directed mutagenesis, a recombinant LIP4 was functionally overexpressed in Pichia pastoris in this study. This recombinant glycosylated(More)
Isoeugenolol (1.0, 3.0, 5.0 mg/kg, i.v.) produced a dose-dependent bradycardia and a decrease in blood pressure in anesthetized Wistar rats. Isoeugenolol inhibited the tachycardia effects induced by (-)isoproterenol, but had no blocking effect on the arterial pressor responses induced by (-)phenylephrine. In isolated guinea pig tissues, isoeugenolol(More)
The effects of tetrandrine, a blocker of voltage-dependent Ca(2+) channels, on ionic currents were investigated in an endothelial cell line (HUV-EC-C) originally derived from human umbilical vein. In whole-cell configuration, tetrandrine (0.5-50 microM) reversibly decreased the amplitude of K(+) outward currents. The IC(50) value of tetrandrine-induced(More)
Capsaicin, the pungent ingredient in hot pepper, activates and subsequently desensitizes a subset of polymodal nociceptors. Because its initial application to skin produces pain, nonpungent analogs such as olvanil and glyceryl nonivamide (GLNVA) were synthesized to enhance its clinical use. To explore how these nonpungent analogs differ from capsaicin,(More)
Various vanilloid-type beta-adrenoceptor blockers were studied on guinea pig right atrium and trachea and rat colon. In addition, we also investigated their beta(1)-, beta(2)-, and beta(3)-adrenoceptor binding affinities. All these beta-adrenergic antagonists inhibited (-)isoproterenol-induced positive chronotropic effects of the right atrium and tracheal(More)
Nonanoyl vanillylamide-4-o-glycerol (glyceryl nonivamide, GLNVA) a nonpungent ether-linked derivative of nonanoyl vanillylamide (nonivamide, NVA) was compared to capsaicin (CAP) and NVA with regard to its depressor response in rats. IV injection of CAP and NVA (10(-1) to 10(-4) mg/kg) in Wistar rats elicit a triphasic blood pressure response, bradycardia,(More)
The effects of glyceryl nonivamide (GLNVA) on ionic currents were compared and examined in rat pituitary GH3 cells. Hyperpolarization-activated K+ currents in GH3 cells bathed in high-K+ Ca2+-free external solution were studied to assess effects of GLNVA on the an inwardly rectifying K+ current (I(K(IR))). GLNVA is very potent in blocking I(K(IR)) in a(More)
OBJECTIVE To determine the rectal tolerance for developing Grade 2 radiation proctitis after 125I prostate implantation based on the rectal dose-volume histogram. METHODS AND MATERIALS Two hundred twelve patients with T1-T2 prostate cancer underwent 125I implantation without external beam irradiation. One month after the procedure, all patients underwent(More)
In this study, the potential anti-inflammatory effect of San-Huang-Xie-Xin-Tang (SHXT) and its main component baicalin on LPS-induced lung injury were investigated and compared to the profile of dexamethasone (DEXA) in a pre-clinical animal model. Post-treatment with SHXT (75 mg/kg), baicalin (1.5 mg/kg) and DEXA (0.5 mg/kg), significantly inhibited(More)
PURPOSE To describe a method of creating an intraoperative dosimetric representation of the real-time ultrasound-guided prostate implant. MATERIALS AND METHODS An intraoperative dosimetry system (Multi Media Systems [MMS]) captures transverse ultrasound images after peripheral needles have been implanted in the prostate. The prostate contour and needle(More)
