Therefore, faecal samples from an entire herd of elands, including calves and adult females and males, were examined monthly over a one year period. Almost 84% of the animals were found to be positive for gastrointestinal nematodes. Strongyle-type eggs were most frequently detected (prevalence ...
Chronic exposure to nicotine during the first postnatal week in rats, a developmental period that corresponds to the third trimester of human gestation, results in sexually dimorphic long-term functional defects in the adult hippocampus. One potential cause could be the sex-specific differences in the...
This study evaluated the effects of sex education on 48 couples in which the women reported secondary orgasmic dysfunction. None of the males had a problem with premature ejaculation or with erectile dysfunction. Couples received two, two-hour sessions of sex education during a one-week period. ...
Between 25 and 60 weeks old, trabecular bone volume decreased by 25 per cent in sections of free thoracic vertebrae (T5) from female birds, the loss occurring at an earlier age in caged birds. Over the sample period, Tsv in male caged birds diminished by 35 per cent, but male floor ...
By restricting the analysis to the last 7 years of the study, it was possible to include the highly polymorphic Pgm-2 locus. During the 7-year period, 653 offspring representing 208 litters were trapped following emergence from the natal burrow. However, electrophoretic data were available at ...
Postnatal treatments abolished and inverted these differences. It is suggested that the AOB development is influenced by sex steroids during at least a postnatal period.关键词: sex differences accessory olfactory bulb vomeronasal system DOI: 10.1016/0165-3806(84)90036-1 被引量: 127 年份: 1984 ...
This study proposes a simple model for explaining changes in attitudes toward premarital sex. It used the fact that new cohorts of 18-year-olds had the same attitudes in the 1970s, 1980s, and 1990s to argue against any linear period effe... DJ Harding,C Jencks - 《Public Opinion Quarterl...
We investigated the effects of the year of birth (cohort effect), sex and birth date on the variations observed in birth weight and postnatal growth rate in 209 newborn fawns marked during eight consecutive fawning seasons from a highly productive roe deer population under good nutritional conditi...
However, irrespective of the effects of LPS, parents equally allocated food among control and challenged offspring both under normal food provisioning and after a short period of food deprivation of the chicks. These results indicate that bacterial infection and the associated immune response entail ...
