Objective. To determine the predictive value of genetic polymorphism N-arylacetyltransferase-2 (NAT-2) gene for assessing risk postoperative adhesive intestinal obstruction in children. Methods. In all children (36 with (main group) and 35 planned patients (comparative group)) acetylation genotype was studied by detecting point mutations NAT-2 using allele-specific amplification method analysis...

UNLABELLED Targeted radiotherapy is a potentially useful treatment for some cancers and may be potentiated by bystander effects. However, without estimation of absorbed dose, it is difficult to compare the effects with conventional external radiation treatment. METHODS Using the Vynckier - Wambersie dose point kernel, a model for dose rate evaluation was created allowing for calculation of ab...

Influence of the season of hatch on the functional characteristics of the pineal gland was examined in neonatal Hi-Line male chickens. The pineal glands from 2-day-old birds hatched in summer and winter, and kept from the day of hatch in artificial lighting conditions (12L:12D), were isolated under dim red light in the middle of the day or night. The pineal glands were analyzed to characterize ...

The N-acetyltransferase-2 gene (NAT-2) has been associated with Parkinson's disease. The genotype associated with slow acetylation has been reported to be increased in patients with Parkinson's disease. Three mutant alleles M1, M2, and M3 of NAT-2 were investigated in 80 patients with idiopathic Parkinson's disease and 161 age matched randomly selected controls from a prospective population bas...

Arylamine N-acetyltransferases (NATs) play an important role in the metabolism of arylamine and hydrazine drugs and many arylamine procarcinogens. The two human N-acetyltransferases, NAT1 and NAT2, are widely distributed in human tissues and are highly polymorphic. Although many xenobiotic procarcinogens and drugs are known mammalian NAT substrates, it is unclear what physiological roles these ...

Arylamine N-acetyltransferases (NATs) are enzymes involved in the detoxification of a range of arylamine and hydrazine-based xenobiotics. NATs have been implicated in the endogenous metabolism of p-aminobenzoyl glutamate in eukaryotes, although very little is known about the distribution and function of NAT in the prokaryotic kingdom. Using DNA library screening techniques and the analysis of d...

Cholesterol transport is essential for many physiological processes, including steroidogenesis. In steroidogenic cells hormone-induced cholesterol transport is controlled by a protein complex that includes steroidogenic acute regulatory protein (StAR). Star is expressed as 3.5-, 2.8-, and 1.6-kb transcripts that differ only in their 3'-untranslated regions. Because these transcripts share the s...

This study investigated the dynamic regulation of IIx-IIb MHC genes in the fast white medial gastrocnemius (WMG) muscle in response to intermittent resistance exercise training (RE), a model associated with a rapid shift from IIb to IIx expression (11). We investigated the effect of 4 days of RE on the transcriptional activity across the skeletal MHC gene locus in the WMG in female Sprague-Dawl...
