ABSTRACT
The concentrations of the key factors of molecular pathogenesis of prehypertension (angiotensin II, HLDF24, S100b, endothelin, autoantibodies to these molecules, and VEGF) were analyzed in subjects with optimal BP (<120/80 mm Hg) and prehypertension (120-139/80-89 mm Hg). Comparative and correlation analysis of the levels of these molecules was performed. A statistically significant decrease in HLDF24 level in prehypertension in comparison optimal BP was observed. Specific features and interactions between the studied factors in optimal BP and in prehypertension were studied. The mechanisms underlying the observed associations between serum concentration of HLFF24 and the development of prehypertension were discussed.

We studied concentrations of angiotensin II, HLDF24 peptide, endothelin proteins, S100B, and autoantibodies to them and serum levels of blood natriuretic peptide in patients with different categories of "normal" arterial BP and hypertension. The relationship between blood levels of the above factors and normotony, pre-hypertension, and hypertension in the examined groups was analyzed. The results suggest that the studied molecular factors can serve as potential predictors of arterial hypertension and used for personalized hypertension risk assessment.

The content of S100b protein, HLDF24 peptide, and autoantibodies to these factors in blood serum was measured in healthy individuals (35-64-year-old men and women) with various levels of "normal" BP. Significant differences in the amount of these molecular factors were found in individuals with various categories of BP. We revealed age-related and gender differences in the content of molecular factors in the serum. Our results indicate that variations in the concentration of S100b, HLDF24, and autoantibodies to these factors in blood serum from adult people can serve as a reliable criterion for the risk of arterial hypertension.

The results of the polymerase chain reaction studies performed in 2006-2008 were used to make a retrospective analysis of the detection of urogenital herpesvirus infections in reproductive-aged women constituting the urban population of the central region of Russia. The study used both monotarget and mutiplex test systems to detect herpes simplex virus (HSV), cytomegalovirus (CMV), Epstein-Barr virus (EBV), human herpesvirus types 6 and 7. A total of about 7.500 referrals; the detection rate for HSV was about 1%; that for CMV was from 0.3 in 2006 to 1% in 2008; that for EBV was from 0.1% in 2006 to 0.3% in 2008. More than a half of HSV-, CMV-, or EBY-positive samples also contained DNA of other causative agents and some samples did two pathogens or more. Multiplex test systems for herpesviruses considerably enhance the efficiency of diagnostic studies and reduce the material and time costs of diagnosis.
