The antioxidant activities of curcumin, its natural demethoxy derivatives (demethoxycurcumin, Dmc and bisdemethoxycurcumin, Bdmc) and metabolite hydrogenated derivatives (tetrahydrocurcumin, THC; hexahydrocurcumin, HHC; octahydrocurcumin; OHC) were comparatively studied using 2,2-diphenyl-1-picrylhydrazyl (DDPH) radical,(More)
Mycophenolic acid (MPA) is an effective treatment for active lupus nephritis despite its variable efficacy in different ethnic groups. Here we tested whether pharmacokinetic monitoring may help to optimize dosing of MPA in an Asian population. Patients with biopsy-proven class III or IV lupus nephritis (ISN/RPS category) were treated with mycophenolate(More)
BACKGROUND Plasma mycophenolic acid (MPA) concentrations may predict therapeutic response in active lupus nephritis (LN). We determined the efficacy and safety of a concentration-controlled MPA regime in the treatment of severely active LN. METHODS In this prospective study, 19 biopsy-proven class III/IV LN patients were treated with mycophenolate mofetil(More)
A study of thermal stress risk for cattle and buffalo was made in the Northeast Region of Thailand. Three-hourly air and dew-point temperatures from 15 selected meteorological stations for the period 1990 to 1999 were used to compute values of the temperature/humidity index (THI). Maps of isolines of THI values were generated by geographical software. A THI(More)
OBJECTIVE Mycophenolic acid (MPA) has become the first-line drug therapy for proliferative lupus nephritis, a common and serious complication of systemic lupus erythematosus. Although a sufficient MPA exposure is required, a high interindividual variability in the pharmacokinetics of MPA has been observed. The knowledge of MPA pharmacokinetics in lupus(More)
Although renal histopathology is the gold standard for the diagnosis and prognosis of lupus nephritis (LN), the invasiveness of renal biopsy warrants the discovery of novel non-invasive diagnostic and prognostic biomarkers. In the present study, urine samples from 10 LN patients (5 active and 5 inactive) were analyzed by two-dimensional gel electrophoresis(More)
 The prevalence of cerebral meningitis caused by Cryptococcus neoformans in HIV-infected patients in Eastern Thailand is high. However, little is known about the occurrence of this pathogenic yeast in the environment of this region.  The aim of our study was to characterize the prevalence of C. neoformans, its serotypes and antifungal drug susceptibilities(More)
INTRODUCTION BLyS and APRIL are cytokines from the tumor necrosis factor family which play an important role in systemic lupus erythematosus (SLE). Previous works suggested an association between both molecules and SLE disease activity although their correlation with lupus nephritis is not known. We therefore assessed serum BLyS and APRIL in active lupus(More)
Exosomes, derived from multivesicular bodies (MVBs), contain proteins and genetic materials from their cell of origin and are secreted from various cells types, including kidney epithelial cells. In general, it is thought that protein cargo is ubiquitylated but that ubiquitin is cleaved by specific deubiquitylases during the process of cargo incorporation(More)
Nanovesicles present in urine the so-called urinary exosomes have been found to be secreted by every epithelial cell type lining the urinary tract system in human. Urinary exosomes are an appealing source for biomarker discovery as they contain molecular constituents of their cell of origin, including proteins and genetic materials, and they can be isolated(More)
