We perform a comprehensive analysis of multi-band absorption by exciting magnetic polaritons in the infrared region. According to the independent properties of the magnetic polaritons, we propose a parallel inductance and capacitance(PLC) circuit model to explain and predict the multi-band resonant absorption peaks, which is fully validated by using the(More)
Excipients are largely used as inert vehicles in formulation. Recent studies indicated that some excipients could affect drug transport and disposition. But the effects of most excipients on drug metabolism are yet to be unveiled. To evaluate the actual action of pharmaceutical excipients in biotransformation, we examined the effects of 22 common excipients(More)
The aim of this work was to investigate the effects of pluronic F68 block copolymer on the P-gp-mediated transport of celiprolol (CEL) and CYP3A4-mediated formation of midazolam (MDZ) metabolite 1'-hydroxymidazolam. Over a range from 0.03 to 0.3%, pluronic F68 increased apical-to-basolateral permeability (AP-BL) and decreased basolateral-to-apical(More)
BACKGROUND Guanine-rich sequence of c-myc nuclease hypersensitive element (NHE) III1 is known to fold in G-quadruplex and subsequently serves as a transcriptional silencer. Cellular nucleic-acid-binding protein (CNBP), a highly conserved zinc-finger protein with multiple biological functions, could bind to c-myc NHE III1 region, specifically to the single(More)
In rats we examined the effects of some common excipients on the intestinal absorption of ganciclovir (GCV), a BCS-III drug and substrate of P-gp, by assessing its in vitro transfer from mucosa to serosa and in situ transepithelial permeation. In vitro, all selected excipients (concentration range 0.1-1% [w/v]) could increase the transport amount of GCV in(More)
PURPOSE The purpose of this study was to explore the risk factors for breast cancer and establish the expression rate of IGF-2 in female patients. METHODS A case control study with 500 people in case group and 500 people in control group. A self-administered questionnaire was used to investigate risk factors for breast cancer. All cases were interviewed(More)
AbstractAim:To investigate the preventive and protective effects of bendazac lysine (BDL) on experimental early diabetic nephropathy (DN) rats.Methods:After an early DN model was induced by streptozotocin, rats were administered BDL at doses of 100, 200, and 400 mg/kg for 8 weeks. Blood glucose, microalbuminuria, kidney index, total antioxidative capacity,(More)
Diabetic nephropathy (DN) has become the leading cause of end stage failure, but no renoprotective treatment has been very available for use in DN. Astragalus saponin I (AS I), a component extracted from Astragalus membranaceus BUNGE, was studied in experimental DN induced by administration of streptozotocin in male rats. The early DN rats were treated with(More)
Astragaloside IV (AGS-IV), a new glycoside of cycloartane-type triterpene isolated from the root of Astragalus membranaceus (Fisch.) Bunge, has been used experimentally for its potent immune-stimulating, anti-inflammatory, and antioxidative actions. A recent study has shown AGS-IV to be an aldose-reductase inhibitor and a free-radical scavenger. This study(More)
To evaluate the genotoxic, physiological and immunological effects of short-term acute low temperature stress on the Pacific white shrimp, Litopenaeus vannamei, we rapidly transferred shrimp from tanks at 23±2 °C to aquaria at the same temperature (controls) or 12±2 °C for 12 h. Changes in the shrimp hemocyte respiratory burst activity and DNA damage were(More)
