[Age-associated features of the development of fibrosis and inflamaging in patients with arterial hypertension and ischemic stroke.].

The article deals with the development of fibrosis and immune inflammation in patients with arterial hypertension and acute ischemic stroke in old age. The aim of the study was to study age-associated features of the concentration of fibrosis markers (metalloproteinase-9, tissue inhibitor of matrix metalloproteinases-1, their ratio MMP-9/TIMP-1), immune inflammation (TNF-α, IL-1β, INF-γ) in patients with arterial hypertension and ischemic stroke (AI). The study included 86 patients with arterial hypertension (AH) of the 2nd degree, of which 42 were middle-aged (53±5 years) and 44 elderly (66±5 years).

[The use of cytoflavin in reperfusion in ischemic stroke].

Objective: to study the efficacy of cytoflavin in thrombolytic treatment of patients with acute ischemic stroke (IS).

Material And Methods: Fifty-five patients in the acute stage of IS were examined. The National Institutes of Health Stroke scale (NIHSS), the Rankin scale and the Barthel index of activities of daily living were used.

Estimation of the toxicity of silver nanoparticles by using planarian flatworms.

The regeneration of planarian flatworms - specifically, changes to the area of the regeneration bud (blastema) after surgical dissection - was proposed for use as a robust tool for estimating the toxicity of silver nanoparticles. The use of Planaria species, due to their unique regenerative capacity, could result in a reduction in the use of more-traditional laboratory animals for toxicity testing. With our novel approach, silver nanoparticles were found to be moderately toxic to the planarian, Girardia tigrina.

[Unification of methods for determining the trace quantities of lead, zinc, sodium and potassium ions in the assessment of drinking water adn transfusion fluid quality].

The results of long-term studies made by the Department of General Chemistry, I. M. Sechenov Moscow Medical Academy, that deals with unification of methods for determining some ions of metals (lead, zinc, sodium, and potassium) in the assessment of the quality of drinking water and transfusion fluids are summarized.
