Humic acids are known for their overall positive health and productivity effects in animal feeding trials and, controversially, as an aetiological factor of cancer. We tried to assess the in vitro effect of humic acids from a selected source in Slovakia when used at recommended prophylactic dosage. We investigated antioxidant properties, enzymatic and(More)
Phenolic compounds from plants are known for their antioxidant properties and have been proposed as therapeutic agents to counteract oxidative stress. However, under normal circumstances, the body only receives a very small amount of these substances in the diet. We have investigated the effect of extracts from known and frequently used plants as part of(More)
OBJECTIVES The objective of this paper is to highlight the selected group of patients in which adjuvant therapy seems to have a more pronounced positive effect. DESIGN AND METHODS 65 septic patients from the prospective observational study Se-AOX (2008-2012) (ClinicalTrials.gov Identifier: NCT02026856) were divided into a Se group, receiving sodium(More)
The aim of the study was to investigate the anti-proliferative activity of brassinin and its derivatives on human cancer cell lines. We found that among twenty-one tested compounds, 1- methoxybrassinin exerted the most potent anti-proliferative activity in Caco-2 cells with IC₅₀ 8.2 (±1.2)μmoll(-1). The flow cytometric analysis revealed a(More)
Metal-containing drugs have long been used for medicinal purposes in more or less empirical way. The potential of these anticancer agents has only been fully realised and explored since the discovery of the biological activity of cisplatin. Cisplatin and carboplatin have been two of the most successful anti-cancer agents ever developed, and are currently(More)
Crohn's disease and ulcerative colitis, known together as inflammatory bowel diseases (IBDs), and celiac disease are the most common disorders affecting not only adults but also children. Both IBDs and celiac disease are associated with oxidative stress, which may play a significant role in their etiologies. Reactive oxygen species (ROS) such as superoxide(More)
OBJECTIVE Antioxidant, anti-inflammatory and venoconstrictor properties have been attributed to extracts from Aesculus hippocastanum. These unusual and diverse properties may be possibly basically linked with ability to scavenge free radicals. MATERIALS AND METHODS The scavenging capacity of dry horse chestnut extract of and escin have been investigated(More)
UNLABELLED Selenium supplementation improves antioxidant status in critically ill patients with severe acute pancreatitis. It depends on quantum of dosage and supplementation time. The aim of this analysis is point out on benefit of antioxidant therapy by supplementing selenium. METHODS Patient with severe acute pancreatitis and developing septic shock(More)
During embryonic and early postnatal development, retinoic acid (RA) regulates genes that control neuronal differentiation and neurite outgrowth from the neural tube. The effects of high levels of RA on the CNS can be detected via nitric oxide (NO), which plays a crucial role in neural transmission. The aim of the study was to investigate the prenatal(More)
