https://www.selleckchem.com/screening/inhibitor-library.html The aim of the study was to retrospectively evaluate the efficiency of extracorporeal shock wave lithotripsy (ESWL) with ultrasound guidance and the results of treatment of children with urolithiasis, of different age groups depending on the stone location and size. A total of 135 children and adolescents, aged from 1 to 18 years treated by ESWL at IZMIRLIAN Medical Center from 2005 to 2016 were enrolled in this study. Number, size and location of stones were evaluated. A total of 153 ESWL sessions were performed, including two sessions in 9 cases, three sessions in 1 case, and four sessions in 2 cases. Intra- and posttreatment stone fragmentation rate, number of ESWL sessions, shock-wave pulses per session, stone-free rate, and number of ancillary procedures depending on the stone location and size as well as radiation exposure were evaluated. Follow-up observation was performed after 14, 30 and 90 days. In most cases, there was a good stone fragmentation after ESWL. From 200 to 3000 low-energy pulses efficiency of ESWL under ultrasound guidance in children and adolescents. Absence of X-ray exposure, minimal complication rate, non-invasiveness and high efficiency allow to consider ESWL as a method of choice for the treatment of urolithiasis in children and adolescents.Genetic factors cause various forms of male infertility in 30-50% of cases. The role of oxidative stress in male infertility has been broadly recognised, and the search for a new marker to determine the redox environment in semen has gained considerable interest. to establish the association of two polymorphic loci Ile105Val, Ala114Val of the GSTP1 gene (glutathione transferase class pi-1) with the parameters of oxidative stress in men with infertility. the main study group consisted of 160 men of reproductive age with infertility (mean age - 29,9+/-5,3 years). The control group included 104 practically healthy men with realized reproductive
