Oxidative stress, i.e., excessive production of oxygen free radicals and reactive oxygen species, leads to lipid peroxidation and to formation of reactive aldehydes which act as second messengers of free radicals. It has previously been shown that oxidative stress may be involved in the transcriptional regulation of cytomegalovirus (CMV) immediate early(More)
This study was aimed to demonstrate the efficacy of interval hypoxic training (IHT) in complex treatment of Helicobacter pylori-associated duodenal peptic ulcer disease (DPUD) by parameters of aerobic metabolism and indexes of heart rate variability (HRV). Eighty patients with H. pylori-associated DPUD were included into the study, mean age 32+/-1.8 yrs,(More)
Breast cancer is a leading cause of mortality and morbidity in women, mostly due to high metastatic capacity of mammary carcinoma cells. It has been revealed recently that metastases of breast cancer comprise a fraction of specific stem-like cells, denoted as cancer stem cells (CSCs). Breast CSCs, expressing specific surface markers CD44(+)CD24(-/low)ESA(+)(More)
Bone regeneration is a process of vital importance since fractures of long bones and large joints have a highly deleterious impact on both, individuals and society. Numerous attempts have been undertaken to alleviate this severe medical and social problem by development of novel bioactive materials, among which bioactive glass is the most attractive because(More)
A previous report from our group had shown in vitro a direct interaction between peroxidases and dietary antioxidants at physiological concentrations, where in the absence of H(2)O(2), the antioxidants could serve as oxidizing substrates for the peroxidases. However, the physiological relevance of those findings had not been evaluated. The main objective of(More)
Liver is a unique mammalian organ with a great capacity of regeneration related to its function. After surgical resection or injury, hepatic cells, especially hepatocytes, can proliferate rapidly to repair the damage and to regenerate the structure without affecting the function of the liver. Loss of catalase activity during regeneration indicates that(More)
