Seasonal changes in lipid droplet size and lipid peroxidation in the brown adipose tissue (BAT) of wild bank voles were examined. In addition, a role of photoperiod in these changes was studied; bank voles were held from the birth under long photoperiod (LP) for 12 weeks, and then half of them was transferred to short photoperiod (SP) for 6 weeks and(More)
Bank voles free living in a contaminated environment have been shown to be more sensitive to cadmium (Cd) toxicity than the rodents exposed to Cd under laboratory conditions. The objective of this study was to find out whether benzo(a)pyrene (BaP), a common environmental co-contaminant, increases Cd toxicity through inhibition of metallothionein (MT)(More)
In the last years the retroviral disease, caused by the human immunodeficiency virus (HIV), turned from an incurable to a chronic disease. This fundamental change happened due to a huge progress in the understanding of the pathogenesis and treatment of this infection. However, one question still remains open: what is the best time to introduce therapy. The(More)
UNLABELLED HCV is responsible for the development of chronic hepatitis C, cirrhosis and hepatocellular carcinoma. The Polish population is mainly dominated by genotype 1 infections, genotypes 3 and 4 are less common. Studies have shown that changes in SNPrs12979860 of human chromosome 19 affect their ability to eliminate infection both spontaneously and(More)
The purpose of this study was to determine whether cadmium (Cd) accumulation and toxicity in the midgut gland of Helix pomatia snails living in a Cd-contaminated area were related to soil pH. Toxic responses in the midgut gland (i.e., increased vacuolization and lipid peroxidation) occurred in H. pomatia snails exhibiting the highest Cd levels in the gland(More)
Langerhans cell histiocytosis is a disorder of unknown etiology characterized by proliferation of histiocytes originating from dendric cells. It usually affects children. LCH is claimed to be a difficult diagnostic challenge. We present a case of multi-organ LCH with severe liver damage. Initial symptoms of disease, the results of additional tests including(More)
The objectives of this study were (1) to determine cadmium (Cd) accumulation in the midgut gland of a land snail Helix pomatia L. inhabiting residential areas of the 14 largest cities in Poland, and (2) to examine whether the accumulated Cd exerted any toxic effects. The average accumulation of Cd in the midgut gland of snails, weighing 16-18 g, ranged from(More)
