Application of titanium dioxide (TiO2) as a photocatalyst has presented a promising avenue for the safe photocatalytic degradation of pollutants. Increasing levels of the release of pharmaceuticals in the environment and formation of the intermediates during their degradation may impose health and environmental risks and therefore require more attention. Photocatalytic degradation of acetylsali...
HE RECENT EMPHASIS on disorders of acid-base metabolism has necessitated a reappraisal of those urinary constituents which represent elimination of acid or base. The conventional expression for urinary acid excretion (“net acid excretion”) is titratable acid bicarbonate + ammonia (T.A. CO2 + NH4 ) (1). It has been the contention of this laboratory that acid excretion is more inclusively represe...
Demand for organic milk is partially driven by consumer perceptions that it is more nutritious. However, there is still considerable uncertainty over whether the use of organic production standards affects milk quality. Here we report results of meta-analyses based on 170 published studies comparing the nutrient content of organic and conventional bovine milk. There were no significant differen...
BACKGROUND Short-chain acyl-CoA dehydrogenase deficiency (SCADD) is a rare inherited mitochondrial fatty acid oxidation disorder associated with variations in the ACADS (Acyl-CoA dehydrogenase, C-2 to C-3 short chain) gene. SCADD has highly variable biochemical, genetic and clinical characteristics. Phenotypes vary from fatal metabolic decompensation to asymptomatic individuals. SUBJECT AND M...
Young children are at increased risk for valproic acid (VPA) hepatotoxicity. Urinary organic acid profiles, as a surrogate of mitochondrial function, were obtained in children 1.9 to 17.3 years of age (n = 52) who were undergoing treatment with VPA for seizure disorders. Age-matched patients receiving treatment with carbamazepine (CBZ; n = 50) and healthy children not undergoing treatment (n = ...
preparing a resin to recognize a target molecule,1 since it needs no precise design for preparing host compounds (supramolecules), such as crown ethers, cryptands, and cyclodextrins. Many imprinted resins have been prepared as sensors2 and for separating herbicides3 and enantio-isomer compounds.4 We have successfully prepared imprinted resins by a surface imprinting method for metal-chelation u...
1Department of Ecology, International Center for Science, High Technology & Environmental Sciences, Kerman, Iran *Corresponding author: [email protected] Abstract: Regarding to excess entry of heavy metals to the natural resources and the importance of heavy metals removal from the environment, in this investigation, the effect of some organic acid treatment on cadmium and lead abs...
Recent advances in the development of microfabricated lab-on-a-chip analysis systems have enhanced the feasibility and capabilities of in situ chemical and biochemical analyzers. While a wide variety of bio-organic molecules can be probed, we have focused our initial studies on the development of an amino acid analyzer with the hypothesis that extraterrestrial life would be based on homochiral ...
This study was conducted to evaluate effects of an organic acid at three levels of dietary electrolyte balances (DEB) on growth performance، acidity and gut microbial population of broiler chickens. A total of 720 as-hatched Ross 308 broilers were used in the study from day 1 old to 40 days of age. The experiment was carried out using a complete block design with factorial arrangement (2×3)....
We report here a case of maternal 3-methylcrotonyl-coenzyme A carboxylase (3-MCC) deficiency in a Korean woman. Her 2 infants had elevated 3-hydroxyisovalerylcarnitine (C5-OH) on a neonatal screening test by liquid chromatography-tandem mass spectrometry (LC-MS/MS), but normal results were found on urine organic acid analysis. The patient was subjected to serial testing and we confirmed a mater...
