Humans are increasingly coming into direct physical contact with robots in the context of object handovers. The technical development of robots is progressing so that handovers can be better adapted to humans. An important criterion for successful handovers between robots and humans is the predictability of the robot for the human.

Objectives: of the study: to evaluate the effectiveness and safety of intermittent catheterization in the management of acute urinary retention and to identify factors influencing the resume normal voiding and the development of adverse events.

Materials And Methods: 129 patients admitted to urology department with acute urinary retention due to BPH were randomized into two groups. Group I had indwelling bladder catheterisation using Foly catheter.

Article Synopsis
  • The study focused on developing a surgical algorithm for accessing the renal collecting system for mini-PCNL without the need for ureteral catheterization, which can prolong surgery time and increase costs.
  • A total of 82 patients with kidney stones underwent the procedure, achieving successful puncture access in all cases using a specific series of steps including fluid infusion and the use of X-ray and ultrasound guidance.
  • The algorithm proved effective, with successful access to the kidney's collecting system in 100% of patients, demonstrating its feasibility as a non-catheterization approach.

Bladder neck contracture after prostate surgery is a rare but feared complication. The treatment of choice is endoscopic incision or resection of fibrotic tissue. In case of ineffective transurethral correction, bladder neck reconstruction has to be done.

Article Synopsis
  • The paper explores the dynamics of nonholonomic systems, specifically the Chaplygin sleigh and the Suslov system, focusing on how their mass distribution changes periodically.
  • It presents a specific system of differential equations to describe the behavior of velocities and investigates conditions under which these systems can experience indefinite acceleration, a phenomenon analogous to Fermi's acceleration.
  • The authors prove that the variable v can exhibit different growth behaviors based on coefficient choices and identify certain areas in phase space where initial conditions can lead to acceleration, employing a unique approach to averaging in their analysis.

Small everyday gestures such as a tap on the shoulder can affect the way humans feel and act. Touch can have a calming effect and alter the way stress is handled, thereby promoting mental and physical health. Due to current technical advances and the growing role of intelligent robots in households and healthcare, recent research also addressed the potential of robotic touch for stress reduction.

This study is part of long-term research in the gene pool of Dagestan ethnic groups. The phenotype (in percent), gene, and haplotype frequencies in three Avar populations are reported. A total of 37 alleles of 13 loci of immune and biochemical genetic marker systems (ABO, Rhesus, P, Lewis, HP, GC, C'3, TF, 6PGD, GLO1, ESD, ACP, and PGM1) have been studied.

Analysis of the genetic variation of eight aboriginal Dagestan ethnic groups based on data on the AB0 and Rhesus blood groups has been carried out in a total sample of 18 348 subjects. The degree of genetic differentiation (G(ST)) and the levels of intraethnic (H(S) and interethnic (H(T)) variations of Dagestan ethnic groups have been estimated at two hierarchical levels of the population system. Prevalence of intraethnic diversity over interethnic one has been found in Dagestan populations.

Detailed analysis of the population structure of Dagestan ethnic groups based on data on the ABO and Rhesus blood groups has been carried out. A total of 32101 representatives of the nine largest ethnic groups of Dagestan (from 682 auls in 46 raions) have been examined. This allows a comprehensive genetic landscape of the Dagestan population to be drawn.

The study was undertaken to reveal the clinical and epidemiological features of development diabetes mellitus (DM) and pulmonary tuberculosis (PT) in comorbidity. The material of the study was 143 case histories and outpatient cards of patients with DM and PT who were registered in 2001-2006. A total of 11,702 cases of tuberculosis were notified in 1999-2005.

The rate of use of pesticides and mineral fertilizers in the Republic of Daghestan was high in the USSR and Russia and was many times greater than the critical burden (3/93 kg/ha) and ranged from 3.5-4.2 kg/ha in the highlands to 17.

Analyzing the results of Mantoux tests with 2 TE made 7 times for 5 years in 750-850 schoolchildren of the settlement of Sulak has demonstrated that the infection rates are on the increase on the one hand, and, due to material and transport problems, the proportion of examinees from a risk group decreases to 10-30% of those to be examined, on the other hand. The authors suggest that the remaining unexamined children should undergo chemotherapy with 2-3 antituberculosis drugs for 3 months so as to perform an examination when the first opportunity occurs. They propose to examine the coverage of children, except for children and adolescents with a hyperergic and increasing reactions and those with a highly positive (15-16 mm) Mantoux test.

The epidemiological features of tuberculosis among rural males in Daghestan were studied. Its mortality in males was found to greatly vary by climatic and geographic areas by the east-west and north-south axes. 1990 to 1997 were marked by a rise in tuberculosis morbidity by both ecological and administrative areas.
