Summary: This study aimed to evaluate and compare the level of cortisol variation in hair and saliva among dental students of both genders. Saliva and hair samples were collected from 151 students, and the levels of cortisol were measured using ELISA. The results showed significant differences in cortisol levels between saliva and hair, as well as between male and female students.

Summary: The study findings indicate that maternal perceived stress did not affect fetal cortisol levels, cortisone levels, or birth weight, but were positively correlated with maternal BMI. Furthermore, hair progesterone levels were positively associated with stress, while cord estradiol levels were negatively associated with stress.

Summary: Studies have shown that exposure to organic pollutants may alter sex steroid hormone levels in animals and humans. However, research on the mixture effects of these pollutants is limited, and the focus has been mainly on persistent organic pollutants. In this study, hair analysis was used to evaluate the relationship between multiclass organic pollutants and sex steroid hormones in healthy Chinese women. The results showed that each hormone was associated with a mixture of at least 10 examined pollutants.

Summary: This study is the first to explore using tail-hair to assess the physiological history of elephants, finding that cortisol levels in tail-hair correspond to different biological events. The results suggest that tail-hair can be a potential 'retrospective' calendar of an animal's physiological health.

Summary: The study found a positive association between total skin lesion counts 3 weeks post-mixing and the number of mummified piglets and IUGR scores, suggesting that chronic stress might have a negative impact on sow reproductive performance. However, no significant associations were found between hair cortisol concentrations, skin lesion counts, and measures of reproductive performance.

Summary: Confining sows to farrowing crates did not significantly affect hair cortisol concentrations, but differences were found in hair growth rates within different regions. The study suggests that hair cortisol measurement may be limited in comparing chronic stress levels in sows kept in different farrowing systems.

Summary: This study examines the impact of factors such as hair type, race, and outdoor exposure on cumulative hair cortisol concentrations. The results demonstrate the influence of hair sample weight, external exposure, and hair type on cortisol levels. Additionally, differences in cumulative cortisol were found between different racial groups and various hair types. These findings highlight the importance of considering hair type and race when measuring hair cortisol in future studies.

Summary: The menstrual cycle affects cognition through fluctuations in estradiol and progesterone. This study examined the performance of naturally cycling women and women using oral contraceptives using the ANT-I test. The results showed that naturally cycling women had different performance in the follicular and luteal phases, while women using oral contraceptives performed consistently at both time points.

Summary: The study found that exposure to more greenness during the first trimester was associated with reduced maternal cortisol levels. This association was particularly strong among those of lower sociodemographic status. The findings suggest potential benefits of promoting greenness exposure during early pregnancy for disadvantaged populations.

Summary: Males and females in the rock hyrax population exhibit different patterns of leadership. In moderate risk situations, younger resident males are more likely to take leadership roles, while males with lower centrality status are more likely to lead during acute predation scenarios. In contrast, leadership among group females is more evenly distributed.

Summary: Rhythmic stability is important for neural and physiological functions, and the study found that male rock hyraxes with more frequent singing events tend to have more surviving offspring. The rhythmic profile of hyrax songs is predominantly isochronous, and the ratio of isochronous vocal element transitions to off-integer transitions is positively correlated with male reproductive success.

Summary: Competition among group-living animals often leads to a dominance hierarchy, with larger individuals dominating smaller ones. However, in some species, despite being smaller, females dominate several males. This study investigated the association between female dominance and the percentage of males in a group using data from rock hyrax groups. The results support the hypothesis that the winner-loser effect contributes to female dominance over males, and that the association between male percentage and female dominance requires multiple males in the group.

Summary: The predation-stress hypothesis is used to explain the negative effect of predation risk on reproduction, but in some cases, stress appears to increase the reproductive potential of animals. Research found that female wild boars under high hunting pressure may have higher levels of reproductive hormones, leading to increased reproductive potential.
