The benefit of sleep in general for memory consolidation is well known. The relevance of sleep characteristics and the influence of hormones are not well studied. We explored the effects of a nap on memory consolidation of motor (finger-tapping-task) and verbal (associated-word-pairs) tasks in following settings: A: young, healthy males and females during early-follicular phase (n=40) and B: fe...

Primary dysmenorrhea is one of the most common gynecological complaints in young women, but potential peripheral immunologic features underlying this condition remain undefined. In this paper, we compared 84 common cytokine gene expression profiles of peripheral blood mononuclear cells (PBMCs) from six primary dysmenorrheic young women and three unaffected controls on the seventh day before (se...

Female sex hormones have been related to nasal Staphylococcus aureus carriage in healthy individuals; however, whether nasal staphylococcal carriage varies by menstrual cycle phase remains unknown.We sampled anterior nares of female healthcare workers twice per week for 6 consecutive menstrual cycles. We used mixed-effects Poisson regression models to determine whether intermittent carriage was...

Background: According to the biopsychosocial model, menstrual symptoms are caused not only by a combination of biological factors such as hormonal disorders and lifestyle, but also by psychological and social factors such as working environment. This study aimed to determine the relation between occupational stress and dysmenorrhea in Iranian midwives. Materials and Methods: This prospective co...

Successful isolation of human endometrial stem cells from menstrual blood, namely menstrual blood-derived endometrial stem cells (MenSCs), has provided enticing alternative seed cells for stem cell-based therapy. MenSCs are enriched in the self-regenerative tissue, endometrium, which shed along the periodic menstrual blood and thus their acquisition involves no physical invasiveness. However, t...

Gender differences in asthma have been observed with a preponderance of boys affected before puberty and girls during and after puberty. The known influences of the menstrual cycle on asthma support a role for female sex hormones on the changing expression of asthma during adolescence. The purpose of this study was to investigate obesity, the menstrual cycle and lung function in adolescent girl...

-This study examines cell turnover within the lobules of the "resting" human breast and correlates it to the stage of the menstrual cycle. The results are based on the morphological identification of both cell multiplication (mitosis) and cell deletion (apoptosis). It is found that these events undergo significant cyclical changes during the menstrual cycle, with raised levels towards the end o...

Reproductive and menstrual characteristics, as well as high circulating estrogen concentrations, are associated with risk of hormone-related cancers in postmenopausal women. To explore possible etiologic relationships between menstrual/reproductive characteristics and risk of hormone-related cancers, we examined associations between menstrual/reproductive factors and serum concentrations of fre...
