[Initial experience in clinical application of thulium laser contact lithotripsy for transurethral treatment of urolithiasis].

Introduction: The choice of an effective and safe method of disintegration of stones in upper and lower urinary tract is very important in the context of continuous scientific and technological progress. In current clinical urological practice, various lithotriptors with rigid and flexible probes are used for contact disintegration of stones, having both advantages and disadvantages. This study aimed to analyze the first results of the clinical application of the native Tm: fiber Urolaz laser (STA IRE-Polyus, Russia) for contact transurethral lithotripsy.

In vitro phosphorylation of the N-terminal half of hordeivirus movement protein.

The N-terminal half of TGB1 movement protein of poa semilatent hordeivirus, which forms a ribonucleoprotein complex involved in movement of the viral genome in the plant, and its two domains, NTD and ID, are phosphorylated in vitro by a fraction enriched in cell walls from Nicotiana benthamiana. Using a set of protein kinase inhibitors with different specificities, it was found that enzymes possessing activities of casein kinase 1, protein kinase A, and protein kinase C are involved in phosphorylation. Commercial preparations of protein kinases A and C are able to phosphorylate in vitro recombinant proteins corresponding to the N-terminal half of the protein and its domains NTD and ID.

[Metabolic syndrome and erectile dysfunction].

Aim: To study aspects of erectile dysfunction (ED) pathogenesis in patients with metabolic syndrome (MS) and its diagnosis.

Material And Methods: Epidemiology of ED in MS patients was studied by determination of MS prevalence among patients with organic ED (MS diagnosis according to NCEP/ATP III criteria), questionnaire assessment of erectile function in MS patients observed by the cardiologist or therapist. ED patients with MS (n = 385) entered the study group.

[Modification of mutation processes in culture of human lymphocytes with tea extracts].

Antimutagenic activity of the extracts of tea leaves from different stages of technological processing has been investigated. Culture of human lymphocyte cells was used as a test-object. Mutations have been induced with gamma-rays, N-methyl-N1-nitro-N-nitrosoguanidine (MNNG) and benz-[a]-pyren.

[Development of the trypanosomes (Trypanosoma) and cryptobians (Cryptobia) of carp and tench in the leech Piscicola geometra].

The paper presents the results of studies of the development of trypanosomes and cryptobiae of carp and tench in Piscicola geometra. The paper describes an unknown way of reproduction by means of fusion of individuals and formation of cystlike bodies, the subsequent development of which results in a special form schizogony with a formation of rosettes.
