We investigated the sex ratio of children of pesticide workers who produced the biocide trichlorophenol and the herbicide 2,4,5-trichlorophenoxy acetic acid from 1961 to 1988 in the city of Ufa, Bashkortostan, Russia. We measured exposure of the two related cohorts to 2,3,7,8-tetrachlorodibenz...
The aim of this study was to consider digit ratio (2D:4D: a putative marker of prenatal testosterone and estrogen levels) and aggression in a sample of 1,452 children and adolescents (mean age 13.6 years) from five regions of Russia. The 2D:4D was calculated from direct measurements of th...
Sex differences in rates of obesity in bipolar disorder: postulated mechanisms The increased standardized mortality ratio (SMR) from cardiovascular disease (CVD) in women with bipolar disorder (BD), relative to men with BD and individ... A Baskaran,DS Cha,AM Powell,... - 《Bipolar Disorders》...
Background The apparent contradiction that women live longer but have worse health than men, the so called male-female health-survival paradox, is very pronounced in Russia. The present study investigates whether men in Moscow are healthier than women at the level of biomarkers, and whether the ...
Both were correlated with marital status, weekly alcohol consumption, age at first sex, and number of lifetime sexual partners. Partner concurrency was significantly associated with diagnosed STDs (odds ratio = 2.06; 95% confidence interval = 1.35-3.15). No significant association between individual ...
During the first month in sex work, such FSWs had higher odds of sexual violence (adjusted odds ratio [AOR], 3.1; 95% confidence interval [CI], 1.6-6.1), ≥7 clients per day (AOR, 3.3; 1.8-6.1), no use of condoms (AOR, 3.8, 2.1-7.1), and frequent alcohol use (AOR, 1.9; ...
Logistic and Poisson regression analyses assessed associations of IPV with STI and risky sex. Most women (78%) experienced IPV and 19% were STI positive; 15% sold sex. IPV was not significantly associated with STI, but was with selling sex (adjusted odds ratio = 3.56, 95% confidence ...

Effect of some non-conventional fish meal replacers on the growth, feed conversion and body composition of Clarias batrachus (Linn.) fingerlings A 30-day feeding trial was conducted to determine growth, feed conversion ratio and whole body composition of C. batrachus fingerlings (1.15 g) with 3...
The evidence for the author's hypothesis, that the sex ratio may be altered by the ionic environment during fertilization is presented. In the 1930's, it was discovered that the proportion of males increased as the ratio of potassium to calcium + magnesium ions increased for several marine spe...
