Individual Differences in the Response of Human β-Lymphoblastoid Cells to the Cytotoxic, Mutagenic, and DNA-Damaging Effects of a DNA Methylating Agent, -Methylnitrosourethane.

Metabolic activation of many carcinogens leads to formation of reactive intermediates that form DNA adducts. These adducts are cytotoxic when they interfere with cell division. They can also cause mutations by miscoding during DNA replication.

Persistent parvovirus B19 infection in non-erythroid tissues: possible role in the inflammatory and disease process.

Parvovirus B19 (B19V) is a small non-enveloped DNA virus of the Parvoviridae family. It is an obligate human pathogen that preferentially replicates in erythroid progenitor cells. B19V is the causative agent of multiple erythroid-related diseases due to replication-induced cytotoxicity.

[Low level of 25-OH-vitamin D as a marker of critical ischemia in case of diabetic foot syndrome].

It was done the prospective study of the examination results of 40 patients with diabetes mellitus. All patients were divided into 2 groups for study of 25-OH-vitamin D effect, cholesterol, triglycerides in blood serum on the nature of diabetes mellitus. The first group included patients with ulcero-necrotic injuries in case of neuro-ischemic forms of diabetic foot syndrome.

Human parvovirus B19 infection leads to downregulation of thyroid, estrogen, and retinoid hormone receptor expression.

Erythrovirus B19 (B19V) is a member of the family Parvoviridae. Infection with B19V has been linked to a variety of diseases including erythroid, thyroid, neurological and autoimmune diseases. Here we show that infection of primary CD36+ cells with B19V coincides with downregulation of thyroid, retinoid, and estrogen hormone receptors.

[Peculiarities of arterial lesions in patients with critical ischaemia on the background of diabetic foot syndrome].

The authors investigated peculiarities of occlusive and stenotic arterial lesions influencing the pattern of revascularization in patients presenting with a neuroischaemic form of diabetic foot syndrome. We examined a total of 106 patients with a neuroischaemic form of diabetic foot syndrome and undergoing treatment at the City Municipal Centre for Diabetic Foot in the City of Minsk. In order to visualize the arteries in 82 (77.
