Coordination of the carbocyclic ring of hydroquinones to electrophilic transition-metal fragments such as Mn(CO)3+ and Rh(COD)+ produces stable pi-bonded eta6-complexes that are activated to facile reversible deprotonation of the -OH groups. The deprotonations are accompanied by electron transfer to the transition metal, which acts as an internal oxidizing agent or electron sink. With manganese...
BACKGROUND/AIMS SPAK (SPS1-related proline/alanine-rich kinase) and OSR1 (oxidative stress-responsive kinase 1), kinases controlled by WNK (with-no-K[Lys] kinase), are powerful regulators of cellular ion transport and blood pressure. Observations in gene-targeted mice disclosed an impact of SPAK/OSR1 on phosphate metabolism. The present study thus tested whether SPAK and/or OSR1 contributes to ...
BACKGROUND Complementary and alternative medicine (CAM) use is prevalent among HIV-infected patients to reduce the toxicity of antiretroviral therapy. Ginseng has been used for treatment of hyperglycemia and insulin resistance, a common side effect of some HIV-1 protease inhibitors (PI). However, it is unknown whether American ginseng (AG) can reverse insulin resistance induced by the PI indina...
We present the strategic design and synthesis of Os(II) complexes bearing a single pyridyl azolate pi-chromophore with an aim to attain high efficiency blue phosphorescence by way of localized transition. It turns out that our proposal of localized excitation seems to work well upon anchoring a single pi-chromophore on the Os(II) complexes such that the control of MLCT versus pipi* (or even LLC...
INTRODUCTION Antiretroviral agents (ARVs) have a high potential for drug interactions. However, the prevalence and risk factors for clinically significant drug-drug interactions (CSDDIs) with ARVs from Latin American countries is unknown. AIM To evaluate the prevalence and risk factors for CSDDIs in HIV outpatients attending at two centers in Buenos Aires, Argentina. METHODS Descriptive cro...

The microstructures of as-cast and heat-treated Co-Cr-Mo with addition of C, Si and Mn have been investigated with a focus on phase and dissolution of precipitates. The heat treatment temperatures and heating periods employed ranged from 1448 to 1548 K and 0 to 43.2 ks, respectively. The precipitates observed in the as-cast and heat-treated alloys were carbides (M23C6, eta-phase, and pi-phase) ...
Snake venom hemorrhagic metalloproteinases (SVMPs) of the PI, PII and PIII classes were compared in terms of tissue localization and their ability to hydrolyze basement membrane components in vivo, as well as by a proteomics analysis of exudates collected in tissue injected with these enzymes. Immunohistochemical analyses of co-localization of these SVMPs with type IV collagen revealed that PII...
BACKGROUND This study describes the transmission of border disease virus (BDV) from a persistently infected calf to seronegative heifers in early pregnancy, resulting in persistently infected fetuses. On day 50 of pregnancy (= day 0 of the infection phase), six heifers were co-housed in a free stall with a bull calf persistently infected with BDV (pi BVD) for 60 days. The heifers underwent dail...
OBJECTIVES To evaluate the curative effect of albendazole/thalidomide co-therapy on eosinophilic meningitis in BALB/c mice caused by Angiostrongylus cantonensis. METHODS Male mice were infected with 50 A. cantonensis larvae and treated with albendazole (5, 10 or 20 mg/kg per day) alone, thalidomide (25, 50 or 100 mg/kg per day) alone, or a combination of albendazole (10 mg/kg per day) and tha...
