Analysis of algorithms for adaptive control of laser beams in a nonlinear medium.

Adaptive correction for thermal blooming by multidither and phase-conjugation algorithms is analyzed with the use of numerical models of beams propagating in a nonlinear medium. Methods to increase the stability of these algorithms are proposed. The influence of an adaptive mirror on the efficiency and the divergence of correction algorithms is considered.

[Clinical implications of E. coli pathogenic factors in patients with urinary infection].

The authors show perspectives of using primers detecting nucleotide gene sequences in isolated E. coli strains; pathogenic factors of E. coli, fimbrial adhesive (type I and type P); alpha-hemolysin (hly); cytotoxic necrotising factor I (cnf-1); iron-regulated proteins for predicting the course of the inflammatory process in urological patients with bacterial infection.

[Functional status of urinary tract after plastic surgery of the urinary bladder with a segment of the ileum (experimental study)].

Replacement of the gall bladder with an isolated ileal segment was made to evaluate function of the urinary tracts depending on configuration of the created urine reservoir early and late after the operation in dogs. Intestinoplasty of the gall bladder changes parameters of ureteral function. Upper urinary tract urodynamics after ileocystoplasty is characterized by lowering of intraureteral pressure, decreased amplitude of the contractions, high tonicity and motility.

[Effectiveness of imipenem/cilastatin (Tienam, MSD) in treating complicated infections in urology].

Complicated urinary infections tend to eventuate in severe pyoseptic complications--bacteriuria, sepsis. The search for methods of fighting agents of urinary infections goes in the direction of perfection of already existing methods and in the direction of design of novel antibacterial drugs. In the middle 1980s the first carbapenem drug-imipenem--was proposed for urological clinical practice.
