(1)H-MRS and MEGA-PRESS pulse sequence in the study of balance of inhibitory and excitatory neurotransmitters in the human brain of ultra-high risk of schizophrenia patients.

The MEGA-PRESS pulse sequence was used for determination of overlapping signals in the (1)H-MRS spectra of the human brain. For the first time, the balance of GABA glutamate/glutamine concentrations was estimated quantitatively in the human brain of patients with ultra-high risk of schizophrenia. It was found that GABA concentration and GABA/GLX ratios were significantly reduced in the left frontal lobe of UHR subjects.

Organ-sparing treatment for closed spleen injuries in children.

The results of organ-saving treatment for 84 children with closed transcapsular spleen rupture were studied. Criteria for the stipulation of differential curative tactics were present. Twenty-five children were treated conservatively.

Pelvic polyfractures in children. Radiographic diagnosis and treatment.

Results of clinical and radiographic examinations of 43 patients, 4 to 15 years old, with pelvic polyfractures during acute- and long-term periods of trauma, and postmortem and experimental data were presented. A high rate of diagnostic mistakes and treatment failures in patients with pelvic polyfractures are defined. Depending on the location and pattern of pelvis injuries, the main reasons for complications are determined.
