Kinetic and metabolic studies in HPRT deficiency
… 550μU/mg Hb (reference range 1680-2480μU/mg Hb). Studies to determine whether the low hypoxanthine-guanine phosphoribosyltransferase activity was caused by an altered Kₘ of the enzyme for one of its substrates, showed that there was substrate inhibition of the enzyme activity by hypoxanthine. This …

Analytical and metabolic studies of the trypanocidal diamidines
… were no obvious qualitative differences in the metabolic profiles of pentamidine in either of the animals, the rate of metabolism in rats appeared to be faster. Pretreatment of rats with either 3-methylcholanthrene (3-MC), phenobarbitone (PB) or deltamethrin (DM) caused inhibition of pentamidine …

Synthetic and metabolic studies on centrally acting amines
This dissertation is concerned with the metabolic bioactivation of several amines which are either known or suspected to be neurotoxic and with the exploration of bioactivation processes in order to generate metabolites with therapeutic potential. The following three programs were pursued in this …

Metabolic studies on the nitrophile yeast Rhodotorula glutinis DSBCA06
… that we called DSBCA06. We examined the main metabolic features of the strain, also to determine the best growing conditions. At the same time, the ability of the strain to grow in presence of high nitrite concentrations was assayed, being a relevant feature poorly studied earlierfor other …

Structural and Metabolic Studies of Glycosaminoglycans (Sulfatase, Hydrazine, Mucopolysaccharidosis)
… cleavage of the polymer at pH 4.0. Initial studies with heparin-derived model compounds indicated that ester and N-sulfate substituents were stable during N(,2)H(,4) treatment but that uronic acids were converted to hydrazides which were epimerized at C-5 during the hydrazinolysis reaction. …

Biomimetic emulators of high potential peroxygenases: Implications in bioremediation and metabolic studies
Nowadays, classical (bio)remediation processes are affected by some economical and environmental drawbacks. These approaches often seem to be inadequate, particularly in the perspective of sustainable green processes. Since immobilized metalloporphines can emulate the active site of peroxidases and …

Metabolic Studies on 1-Cyclopropyl-4-phenyl-1,2,3,6-tetrahydropyridinyl Derivatives by HPLC and LC-ESI/MS
The MAO-B catalyzed metabolic bioactivation of the parkinsonian inducing agent 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) to generate the neurotoxic 1-methyl-4-phenylpyridinium species (MPP+) is well documented. The N-cyclopropyl analog (CPTP) of MPTP is a mechanism based inactivator of …

Synthetic and metabolic studies on 1-methyl-4-(1-methylpyrrol-2-yl)-1,2,3,6-tetrahydropyridine, a neurotoxic analog of the Parkinsonian inducing agent MPTP
… ethylpyrrol-2-yl)-1,2,3,6-tetrahydropyridine. The metabolic studies of TMMP and MMDP+ were conducted with an HPLC diode array assay. Both in-vivo and in-vitro metabolic studies showed that TMMP is oxidized to its dihydropyridinium species (MMDP+) in a reaction catalyzed by MAO-B. MMDP+ undergoes …

A subspace approach to high-resolution magnetic resonance spectroscopic imaging
… been recognized as a powerful tool for in vivo metabolic studies. However, research and clinical applications of in vivo MRSI have been progressing more slowly than expected. The main reasons for this situation are the problems of long data acquisition time, poor spatial resolution and low …

Selective functionalization of azines via phosphonium salts
… and tritium is installed as a radiolabel for metabolic studies in the pharmaceutical industry. The protocol of the reaction is simple, and it functions on a wide range of building blocks and complex molecules. Additionally, the tritiation protocol was effectively applied on a selection of drug …

Biomimetic design for an under-actuated leg exoskeleton for load-carrying augmentation
Metabolic studies have shown that there is a metabolic cost associated with carrying a load (Griffin et al, 2003). Further studies have shown that by applying forward propulsive forces a person can walk with a reduced metabolic rate (Farley & McMahon, 1992 and Gottschall & Kram, 2003). Previous …

Diurnal and daily variation in creatinine excretion among preadolescent girls consuming three levels of dietary protein
… as a reliable index of protein nutriture in metabolic studies. The apparent contribution of lean body mass to creatinine excretion points to the need for experimental diets which are controlled for preformed creatine and creatinine in order to gain a greater understanding of the true effect …

Interaction of phthalazines with molybdenum hydroxylases. Phthalazine and its 1-substituted derivatives as substrates, inhibitors and inducers of aldehyde oxidase and xanthine oxidase, both in vitro and in vivo.
… been investigated both in vivo and /Ok in vitro. Metabolic studies, carried out by treating rabbits with both cold and 14C-labelled phthalazine, have shown that this compound is extensively metabolised in vivo, the major metabolite being a glucuronide conjugate. Very little unchanged phthalazine …

Integrative Multivariate Analysis of Mouse Liver Acini
… patterns and the spatial separation of metabolic functions, recognized as liver zonation. The factors that govern this spatial phenotypic heterogeneity remain inadequately understood and hepatic pathologies persist as major contributors to global mortality rates. This research aimed to …
