RESUMO
The effects of composite fibroin-gelatin microparticles (100-250 µ) on the rate of wound healing and regeneration under conditions of contraction prevention were studied on the model of splinted full-thickness skin wound in a mouse. Subcutaneous injection of these particles into the defect area accelerated wound healing and promoted re-epithelialization and recovery of normal structure of the epidermis. In addition, the composite microparticles promoted the formation of connective tissue of characteristic structure, replacing the derma over the entire defect, and stimulated regeneration of subcutaneous muscle (panniculus carnosus) and skin appendages (sebaceous glands and hair follicles).

The article presents the results of 257 robot-assisted radical prostatectomies, 135 partial nephrectomies and 32 radical nephrectomies at the period from 2010 to 2016. The operations were performed on robotic complex da Vinci S. The mean operative time was 170±50 min, 158,4±72,2 min and 143,3±67,3 min, the mean blood loss was 130±35 ml, 213,0±102,2 ml and 141,4±49,0 ml for robotic radical prostatectomy, partial and radical nephrectomy, respectively. The mean time of warm ischemia consisted of 13,1±2,7 min. Five-year cancer-specific survival rate was 100%, 100% and 98%. The overall survival rate was 97,5%, 87% and 92% for robotic radical prostatectomy, partial and radical nephrectomy, respectively.
