[Intracorporeal anastomosis in laparoscopic right hemicolectomy: a review of evidence and a single-center experience].

Laparoscopic colon resections are currently becoming a standart method of surgical treatment of colon cancer. Long-term oncologic outcomes of such procedures are shown to be non-inferior to outcomes of traditional open surgery, while short-term results and morbidity profile are more favourable. The current direction of colon mini-invasive surgery development is to make procedures more easily tolerable by patients, using less traumatic methods and operative approaches.

[Choice of local anesthetic volume at the infiltration anesthesia on the upper jaw].

The aim of this study was to investigate the effect of volume and pressure, at which the solution of local anesthetic is injected into the tissue, on the effectiveness of infiltration anesthesia of the periosteum on the upper jaw. We used the technique of tooth pain sensitivity thresholds. According to the rate of development and the duration of the maximum analgesia effect, the optimum volume for different levels of pressure was determined.

Role of oxidative stress and mitochondria in onset of urinary bladder dysfunction under acute urine retention.

Acute urine retention is a frequent complication in patients with benign hyperplasia of the prostate gland. According to studies made on experimental animals and people, it is accompanied by the deterioration of the bladder blood supply. This study attempts to explore the relationship of intramural blood flow, production of reactive oxygen species, and functional state of the bladder detrusor in modeling of acute urine retention in rats, as well as the impact of mitochondria-targeted antioxidants (which are supposed to alleviate the effects of oxidative stress induced by experimental ischemia) on these parameters.

[Taxonomic spectrum and antibiotic resistance of Enterobacteriaceae isolated from bile of patients with cholangitis].

The data on the taxonomic structure and antibiotic resistance of Enterobacteriaceae isolated from bile of patients with various clinical variants of cholangitis are presented. It was shown that bacteriocholia was registered in 53.3-90.
