Saffari " 2015 10 03 Three generations of women (3570 daughters, 1148 mothers and 131 grandmothers) from Tehran, Iran have been studied for menarcheal age. The results show that the age of onset of menarche has decreased in the present generation- 13.599, compared to 13.690 and 13.870 years, amount their mothers and grandmothers, respectively. These results, when compared with results obtained concerning the other Iranian groups, show the effect of both genetic and nongenetic factors on the onset of menarche. https://ijph.tums.ac.ir/index.php/ijph/article/view/1620 https://ijph.tums.ac.ir/index.php/ijph/article/download/1620/1601

The overall sero-positive rate (SPR) was 29 percent with the titers ranging from 1:20 to 1:6400. The number of each species tested and their SPR were: 74 hens (27.0%), 35 roosters (37.1%), 25 turkeys (24.0%), 12 pigeons (33.3%), 8 geese (50.0%) and 8 ducks (0.0%). Altogether 12 strains (7.4%) of T.gondii were isolated from 5 species of the birds, five strains (6.7%) from the hens, one (2.9%) from roosters, four (16.0%) from turkeys, one (8.3%) from pigeons, one (12.5%) from geese and none from the examined ducks. In one case Toxoplasma was isolated from a seronegative hen and the rest were isolated from the sero-positive fowls. All of the isolated strains were no virulent to mice. Since in Iran consumption of underdone chicken-kebab is more or less usual, Toxoplasma infections in domestic fowls any be taken into account as one of the sources of human infection. https://ijph.tums.ac.ir/index.php/ijph/article/view/1621 https://ijph.tums.ac.ir/index.php/ijph/article/download/1621/1602

Mohammadzadeh 2015 10 03 In order to investigate the combined effects of shift work and heat stress on the physiological parameters, such as heart rate (HR) and body temperature (BT), a hot-dry working environment was investigated for 53 workers in foundry workshops. In this study Wet Bulb Globe Temperature index (WBGT) was measured and along with that simultaneously heart rate and oral temperature were checked in 3 shifts. The results indicated that the physiological responses of workers changed whenever the shift changed and the responses were increased by a corresponding increase in heat stress, index. https://ijph.tums.ac.ir/index.php/ijph/article/view/1622 https://ijph.tums.ac.ir/index.php/ijph/article/download/1622/1603

There was a significant difference in infection rate between the snails infected with 2 and those with 10 miracidia (P https://ijph.tums.ac.ir/index.php/ijph/article/view/1623 https://ijph.tums.ac.ir/index.php/ijph/article/download/1623/1604
