The materials and general analytical methods have been described in some detail in a preceding communication (1). The assay method for a-glyeerophosphate dehydrogenase was essentially the same as that of Lowry and Passonneau (2). Since this enzyme catalyzes NADH-coupled reaction with dihydroxyacetone phosphate as substrate, one of the products, NAD2, may be measured with a sonsitive fluorometer...

Objectives: There is inconsistent evidence on the relationship between pesticide exposure and childhood respiratory outcomes in non-agricultural settings. This study investigated association organophosphate (OP) asthma-related children residing four informal settlements. Methods: The was a longitudinal of 590 schoolchildren, with 12 months follow-up period. A standardised questionnaire adopted ...

OBJECTIVE Prenatal exposure to organophosphate pesticides can lead to developmental neurotoxicity. A longitudinal birth cohort was established to investigate pesticide exposures from different agricultural activities. Maternal urinary organophosphate metabolites were measured at 28 weeks of pregnancy (n=86), delivery (n=67) and 2 months postpartum (n=51). METHOD Subjects were interviewed with...

Saponification of extracted tissue phospholipids yields a set of isolated glycerol 3-phosphoryl phospholipid polar headgroups from which semi-quantitative 31P NMR spectra can be obtained. The resonance signals from these molecules, which frequently have been reported as uncharacterized phosphate signals observed in perchloric acid extracts of tissue, can be used as an aid in the characterizatio...

In this study, the influence of eutrophication on arsenic speciation in lake waters was investigated. Surface water samples (n=1-10) were collected from 18 lakes in Japan during July 2007 and February 2008. The lakes were classified into mesotrophic (7 lakes) and eutrophic (11 lakes) based on the total phosphate (T-P) and chlorophyll-a (Chl-a) concentrations in water column. Inorganic, methylat...

Cystinosis is the most common cause of the renal Fanconi syndrome in children, leading to severe electrolyte disturbances and growth failure. A defective lysosomal transporter, cystinosin, results in intralysosomal accumulation of cystine. Loading cells with cystine dimethyl ester (CDME) is the only available model for this disease. This model was used to present electrophysiologic studies on i...

In this paper, a novel nano crystalline sodalite was synthesized and characterized by XRF, XRD, SEM and FTIR analysis. Cu2O nanoparticles (30-60 nm) were loaded on nano zeolite bed and utilized as an adsorbent to remove dimethyl phthalate. The SEM-EDX of modified zeolite indicates that the amount of copper loading on the zeolite was 4.5 wt%. Modified nano zeolite was used as an effective adsorb...

introduction: curcumin is the active ingredient in the traditional herbal remedy and dietary spice turmeric (curcuma longa). curcumin has a surprisingly wide range of beneficial properties, including anti-inflammatory, antioxidant, chemopreventive and chemotherapeutic activity. on basis of recent studies; it has antifungal and antibacterial effects. the aim of this study was in-vitro evaluation...

the effect of modified vitrification was assessed on cellular development capability in mouse embryos cultured in vitro. in this study, 466 embryos (from zygote to morula stages) were vitrified then thawed embryos have been incubated for in vitro farther development up to blastocyst stage. also, vitrification and thawing procedures were the same for all experimental groups. mouse different embr...

The relative free energias of hydration of dimethyl phosphate anion in gauchegauche, gauchetrans, and trans-trans conformations of phosphodiester torsion angles, computed with Monte Carlo method in the (T, V, N) ensemble at 25 OC, are reported. The free energy differences are determined by the probability ratio method using both umbrella sampling with harmonic weighting functions and adaptive u...
