Evaluation of the potential pathogenicity of microorganisms associated with urinary calculi.

Due to the prevalence of postoperative complications in the treatment of urolithiasis, the study of the contamination of urinary calculi and the potential pathogenicity of isolated bacteria is of great importance in laboratory diagnostic practice. It has been shown that uropathogenic bacteria are found in the composition of urinary stones in 65±7.1% of cases, mainly representatives of the Enterobacteriaceae and Staphylococcaceae families.

[The individual approach to energy consumption among the sambo sportsmen].

In the present survey the results of energy expenditure investigation of 14-16 years old (n=100) male sambo athletes', studying at Center of Sport and Education "Sambo-70", at the stage of the instant arrangement for startup, are presented. Serious differences in the level of athletes' energy expenditure depending on training load have been identified in the course of investigations. On the ground of the pre-contest stage training model the combinations of the most common conditioning exercises are determined.

Probing Magnetism in 2D Molecular Networks after in Situ Metalation by Transition Metal Atoms.

Metalated molecules are the ideal building blocks for the bottom-up fabrication of, e.g., two-dimensional arrays of magnetic particles for spintronics applications.

Anticancer substances of mushroom origin.

The present status of investigations about the anticancer activity which is inherent to medicinal mushrooms, as well as their biomedical potential and future prospects are discussed. Mushroom products and extracts possess promising immunomodulating and anticancer effects, so the main biologically active substances of mushrooms responsible for immunomodulation and direct cytoto-xicity toward cancer cell lines (including rarely mentioned groups of anticancer mushroom proteins), and the mechanisms of their antitumor action were analyzed. The existing to date clinical trials of mushroom substances are mentioned.

Some macronutrient content in mycelia and culture broth of medicinal mushrooms cultivated on amaranth flour.

The content of proteins, lipids, and amino and fatty acids was investigated in mycelium and culture broth of medicinal mushrooms Cordyceps sinensis, Pleurotus ostreatus, and Schizophyllum commune. Seven essential amino acids were present in the proteins of all mushroom samples, with aspartic (6.34%-14.

Comparision of two-flow cytometry methods for basophil degranulation in patients sensitized to grass pollen.

Background: Two-flow cytometry methods for quantification of degranulated basophil after allergen-specific activation were discussed. The methods are discerned by used membrane receptors--FcepsilonRI or IL-3Ralpha Our goal was to evaluate the diagnostic potential of the methods and to correlate them to allergen-specific IgE detection and skin prick test (SPT).

Methods: Patient's and control's groups were studied with Bulgarian grass pollen allergen B1 simultaneously by flow cytometry kits: Basotest and BD FastImmune test.

[A novel subspecies of entomopathogenic nematode Steinernema feltiae protense subsp. N.(Nematoda: steinernematidae) from Iakutiia].

A new subspecies of entomopathogenic nematode, Steinernema feltiae protense subsp. n., isolated from Yakutia grasslands is described.

[The distribution of entomopathogenic nematodes of the families Steinernematidae and Heterorabditidae in Russia and their morphological characteristics].

The data on a distribution of nematode species of the families Steinernematidae and Heterorabditidae in the northern and southern regions of the Russian Federation are given. Morphological characters of geographic isolates of some nematode species are not different, while their invasive activities in dependence of a temperature are different. Steinernema feltiae occurs in all climate zones, S.

[Various indicators of the kallikrein-kinin system of the blood in patients of reproductive age with dysfunctional uterine hemorrhage].

Fifteen women with dysfunctional uterine hemorrhages [DUH] of the reproductive period and ten women aged 20 to 30 with normal two-phase menstrual cycle were examined. Measurements of the blood plasma kallikrein and prekallikrein activities in normal females have revealed a direct correlation between kallikrein level and colpocytologic data and an inverse correlation between prekallikrein level and these data. An incessant growth of kallikrein content was detected in DUH patients, whereas their prekallikrein levels were much lower than in the controls.

[Isoenzymes of melanosomal tyrosinase isolated from transplanted hamster melanomas].

The isoenzyme profiles of tyrosinase isolated from melanosomal and cytoplasmic fractions of hamster melanoma were investigated. The liberation of the enzyme from the melanosomal membranes was achieved by their treatment with Triton X-100 or alpha-chymotrypsin. The isoenzyme spectrum of tyrosinase liberated by use of Triton X-100 from melanosomes differing in the degree of melanization is identical to that of the cytoplasmic enzyme and gives three peaks on a densitogram.

[Experimental study of ophthalmic embryopathy of herpetic etiology].

The teratogenic effect of herpes simplex virus was studied in white rats and in organ cultures of rat embryo eye rudiments. In herpetic infection, changes in the lens fibers, delayed formation of the vitreous body cavity, disturbed differentiation of the retina, appearance of typical and atypical colobomas were observed significantly more frequently than in controls. The models used in the study are suitable for experimental investigations of the pathogenesis of ophthalmoembryopathies of herpetic etiology.

[Use of preparation ST 1341 (althesin) in endovesical interventions].

The clinical course of monoanesthesia using ST 1341 (Altezin) preparation during endovesical manipulations and transurethral operative interventions in urology is outlined. The observations are done in a series of 31 patients with systematic study of a number of changes in respiration and hemodynamics, and of their mental and physical state prior to anesthesia and in the period just after awakening. The technique of intravenous Altezin administration does not require special anesthesiologic apparatus.
