[Comparative analysis of the results of treatment of patients with recurrent urethral stricture using platelet-rich plasma].

Introduction: The treatment tactics of patients with recurrent urethral stricture requires an integrated approach. An increase in the treatment efficiency is possible not only through improvements in surgical technique, but also by influencing the pathogenetic mechanisms of the formation of urethral stricture and stimulating regeneration.

Aim: To evaluate the efficiency of reconstructive procedures using platelet-rich plasma in patients with recurrent urethral stricture.

Data-Driven Modeling and Rendering of Force Responses from Elastic Tool Deformation.

This article presents a new data-driven model design for rendering force responses from elastic tool deformation. The new design incorporates a six-dimensional input describing the initial position of the contact, as well as the state of the tool deformation. The input-output relationship of the model was represented by a radial basis functions network, which was optimized based on training data collected from real tool-surface contact.

[Data for substantiation of MPEL of 1,2,4-triazole in the workplace air].

1,2,4-Triazole belongs to the 3-d degree moderately dangerous compounds, according to the parameters of acute intragastric toxicity (LD50). Single and repeated applications of the substance on the skin of rats does not lead to local irritating or skin-resorptive effects. In the native state the substance produces moderate irritating effects on the eye mucosa of rabbits.

[Data for the establishment of maximum allowable concentration of chlorophenoxypinacoline in the working zone air].

Chlorophenoxypinacoline with its acute intragastric toxicity LD50 can be attributed to the 3rd class compounds of hazardousness (moderate hazardous substances). Local irritation and skin resorption effects were not revealed. Irritation of the mucous in the eyes in rabbits was moderate and functional cumulation was insignificant.
