BACKGROUND Few data concerning the oxidative stress (OS) in plasma during the entire menstrual cycle of eumenorrheic women are available. METHODS OS was assessed in 20 healthy volunteers during the phase of the menstrual cycle by determining the plasmatic hydroperoxides levels (d-ROMs test). The assessment was performed every three days, starting from the first day (t1) up the end of the mens...

This study aimed to examine the effects of sex (males vs. females) and sex hormones (menstrual cycle phases in women) on sympathetic responsiveness to severe chemoreflex activation in young, healthy individuals. Muscle sympathetic nerve activity (MSNA) was measured at baseline and during rebreathing followed by a maximal end-inspiratory apnea. In women, baseline MSNA was greater in the midlutea...

BACKGROUND The menstrual cycle exhibits a pattern of repeated inflammatory activity. The present study aims to evaluate inflammatory and endothelial markers during the two phases of a menstrual cycle. METHODS The study cohort consisted of 102 women with regular menstrual cycles. Inflammatory and endothelial markers (interleukin-6 [IL-6], pentraxin-3 [PTX-3], hs-C reactive protein [hs-CRP], sE...

The phase of the menstrual cycle in women who had attempted suicide was determined by structured interview. 108 young women were investigated within 24 h of the attempt. Patients were grouped according to menstrual week and whether they used oral contraception (OC) (n = 73) or not (n = 35). In OC non-users suicide attempts were associated with low plasma oestradiol: they tended to happen during...

BACKGROUND We investigated the detection of chlamydia at different stages of the menstrual cycle. METHODS Electronic medical records for women attending Melbourne Sexual Health Centre between March 2011 and 31(st) December 2012, who were tested for chlamydia by nucleic acid amplification of high vaginal, cervical, or urinary samples, and who recorded a date of last normal menstrual period (LN...

Abstract The longer QT interval duration observed in women compared to men is usually attributed to sexual hormones. The aim of our study was to investigate, among black African women, the influence of hormonal variations during the menstrual cycle on the duration of the QT interval. Fourteen young black African women, healthy, sedentary, aged 24 ± 1.7 years, with a regular menstrual cycle (28 ...

BACKGROUND Characterization of the normal degree of physiological variation in the metabolomic profiles of healthy humans is a necessary step in the development of metabolomics as both a clinical research and diagnostic tool. This study investigated the effects of the menstrual cycle on (1)H nuclear magnetic resonance (NMR) derived metabolomic profiles of urine and plasma from healthy women. ...
