Periodontitis is the most common lytic bone disease and one of the first clinical manifestations of diabetes. Diabetes increases the risk of periodontitis. The aim of the present study was to examine mechanisms by which diabetes aggravates periodontitis. Ligature-induced periodontitis was examined in Goto-Kakizaki rats with type 2 diabetes. A tumor necrosis(More)
The presence of human papillomavirus (HPV) sequences in 21 biopsies from cervical carcinomas, 11 specimens of tissues adjacent to tumours, 2 specimens of cervical tissues with radiation fibrosis from patients after radiation therapy of cervical cancer and 7 normal epithelial tissues from the patients with other genital tumours were examined by polymerase(More)
An aim of the study was to assess the severity of asthenic syndrome, emotional disorders and quality of life indicators in post stroke patients treated with idebenone (noben). We studied 35 patients aged from 47 to 76 years, mean age 58,85±7,99 years, 21 men and 14 women. The time after stroke was 1-8 years (mean 2,63±1,51 years). The duration of follow-up(More)
We report the observation of a frequency shift and splitting of the electron spin resonance (ESR) mode of the low-dimensional S=1/2 frustrated antiferromagnet Cs2CuCl4 in the spin-correlated state above the ordering temperature 0.62 K. The shift and splitting exhibit strong anisotropy with respect to the direction of the applied magnetic field and do not(More)
The spin-excitation continuum, expected to dominate the low-energy fluctuation spectrum in the Haldane spin chain around the Brillouin zone center, q = 0, is directly observed by inelastic magnetic neutron scattering in the S = 1 quasi-1D antiferromagnet CsNiCl3. We find that the single mode approximation fails, and that a finite energy width appears in the(More)
Objective. The evaluation of the dynamics of asthenia, chronic fatigue syndrome, emotional disorders and quality of life of patients with multiple sclerosis (MS) and to explore the possibility of using idebenon (noben) in treatment of these impairments. Material and methods. We studied 35 patients, 18 men and 17 women, with MS (mean age 36.4±8.86 years,(More)
AIM To examine blood flow in renal and intrarenal arteries and its changes in the acute pharmacological test with captopril in patients with chronic glomerulonephritis (CGN). MATERIAL AND METHODS Renal circulation was studied in 50 patients with CGN using ultrasound dopplerography (USDG) of renal vessels on the unit GE Logiq 400 CL PRO Series. The(More)
The authors analyze the results of therapy of 1288 patients with acute submaxillary lymphadenitis, discuss the causes of the development of this condition, and draw attention to the necessity of improving dental care of the population. Comparison of various treatment modalities has demonstrated a high efficacy of radical operation combined with physio- and(More)
Results of prospective randomized comparative research of 2 total hemoglobin estimation methods are presented. There were laboratory tests and continuous noninvasive technique with multiwave spectrophotometry on the Masimo Rainbow SET. Research was carried out in two stages. At the 1st stage (gynecology)--67 patients were included and in second stage(More)
