This review considers the mechanisms and factors that stimulate transcription of genes regulated by the antioxidant responsive element (ARE). The latter is important for cell defense under conditions of oxidative stress and also for detoxification of electrophilic xenobiotics. There are differences in regulation of intracellular homeostasis involving(More)
In this review, we analyze the current hypotheses regarding energy metabolism in the neurons and astroglia. Recently, it was shown that up to 20% of the total brain's energy is provided by mitochondrial oxidation of fatty acids. However, the existing hypotheses consider glucose, or its derivative lactate, as the only main energy substrate for the brain.(More)
The frequency of individual genotypes GSTM1, GSTT1, and GSTP1 and haplotypes was determined in patients with atopic dermatitis and healthy children. The actual frequency of some haplotypes was far below the theoretical value. Some haplotypes were associated with predisposition and resistance to atopic dermatitis.
Mycobacterium tuberculosis is an intracellular pathogen that persists within macrophages of the human host. One approach to improving the treatment of tuberculosis (TB) is the targeted delivery of antibiotics to macrophages using ligands to macrophage receptors. The moxifloxacin-conjugated dansylated carboxymethylglucan (M-DCMG) conjugate was prepared by(More)
Asthmatic (n = 100) and health (n = 104) children were compared for rates of homozygous deletions of the glutathione S-transferase class mu and theta genes (null genotypes, GSTM1"-" and GSTT1"-", respectively). The frequency of GSTM1"-" and GSTT1"-" genotypes in patients with bronchial asthma (BA) (52 [symbol: see text] 26%) were increased compared to(More)
72 Among the most common neurodegenerative dis eases, Parkinson’s disease (PD) is ranked second after Alzheimer’s disease in prevalence. The pathogenesis of PD, as well as that of other neurodegenerative dis eases, is related to oxidative stress, but it is not fully understood yet. Environmental factors, such as pesti cides provoke the development of PD in(More)
The basic metabolic cytochrome P450 (CYP) system is essential for biotransformation of sterols and xenobiotics including drugs, for synthesis and degradation of signaling molecules in all living organisms. Most eukaryotes including free-living flatworms have numerous paralogues of the CYP gene encoding heme monooxygenases with specific substrate range.(More)
We studied the effect of BSA (in the isolation medium) on the oxidation rate of succinate, glutamate, pyruvate, and α-ketoglutarate by mitochondria of the brain and liver from C57Bl/6g mice and Taconic Sprague Dawley rats. BSA had no effect on liver mitochondrial respiration, but increased oxidation of substrates (particularly of succinate) in brain(More)
We determined the prevalence of GSTP1-Ile105 and GSTP1-Val105 alleles in patients with bronchial asthma and atopic dermatitis and healthy children of 2 groups (randomized and nonatopic control). The GSTP1-Ile105/Val105 genotype determines the resistance to atopic dermatitis (odds ratio=0.51; 95% confidence interval: 0.28-0.92; p=0.023). However, both(More)
