BACKGROUND Cortisol is frequently used as a marker of physiologic stress levels. Using cortisol for that purpose, however, requires a thorough understanding of its normal longitudinal variability. The current understanding of longitudinal variability of basal cortisol secretion in women is very limited. It is often assumed, for example, that basal cortisol profiles do not vary across the menstr...
Previous studies of the effect of hormonal changes across phases of the menstrual cycle on voice onset time (VOT) have not considered the variable of oral contraceptive use. The purpose of this study was to examine both the effects of menstrual cycle phase and that of oral contraceptive use on VOT. It was hypothesized that women taking oral contraceptives would exhibit smaller VOT differences a...
Introduction: Various phases of menstrual cycle not only affect reproductive system but other systems also. So this study was performed to see effect of various phases of menstrual cycle on nasal mucosa. Materials and methods: Study was performed on 30 healthy female medical students of 18-24 years having regular menstrual cycles. Nasal mucociliary clearance (NMC) time was recorded during menst...
Exacerbation of certain medical conditions at specific phases of the menstrual cycle is a well-recognized phenomenon. We review the effects of the menstrual cycle on medical conditions, including menstrual migraine, epilepsy, asthma, rheumatoid arthritis, irritable bowel syndrome, and diabetes. We discuss the role of medical suppression of ovulation using gonadotropin-releasing hormone agonists...
Increased wave reflection is an independent factor associated with cardiovascular diseases, risk, and mortality. The influence of the menstrual cycle on wave reflections and particularly on the reproducibility of their measurement has never been examined. The aim of the present study was to examine the reproducibility and variability of wave reflection indices in premenopausal healthy women dur...
Objective This study aimed to determine whether the menstrual characteristics are different in Korean women with or without ovarian endometrioma. Methods We selected 95 premenopausal women aged below 39 years who underwent laparoscopic surgery for ovarian endometrioma (n=46) or other benign ovarian tumors (n=49) between April 2016 and February 2017. We excluded those with uterine diseases tha...
BACKGROUND/AIM To investigate differences in state anxiety, spinal posture and mobility, postural competency, and stability across the menstrual cycle in active women. MATERIALS AND METHODS Thirteen physically active women (18-25 years) with a regular menstrual cycle were recruited. Anxiety with the Spielberger State Trait Anxiety Inventory; spinal posture, mobility, and competency with a Spi...
Prospective pregnancy studies are a valuable source of longitudinal data on menstrual cycle length. However, care is needed when making inferences of such renewal processes. For example, accounting for the sampling plan is necessary for unbiased estimation of the menstrual cycle length distribution for the study population. If couples can enroll when they learn of the study as opposed to waitin...
We investigated the temporal relationship between abdominal temperature, physical activity, perineal swelling, and urinary progesterone and estradiol concentrations over the menstrual cycle in unrestrained captive baboons. Using a miniature temperature-sensitive data logger surgically implanted in the abdominal cavity and an activity data logger implanted subcutaneously on the trunk, we measure...
Human thioredoxin, a cellular disulphide reducing protein, is known to be secreted by some types of cells and to display unique extracellular activities including modulation of cytokine actions and protection of the cell against damage from oxidative stress. This study has been undertaken to investigate the pattern of expression and tissue distribution of thioredoxin in human endometrium during...
