INTRODUCTION Hormonal fluctuations may influence fibrin structure. During the menstrual cycle, plasma fibrinogen levels change, mainly due to the variations of estrogen. Throughout the menstrual cycle estrogen levels peak twice, first during the mid-follicular phase and then a lower second peak during the luteal phase. MATERIALS AND METHODS In order to investigate the possible changes in the ...

Triple X syndrome 47XXX is a sex chromosome abnormality characterized by presence of an extra X chromosome. Most of the girls born with triple X chromosomes have no signs or symptoms at birth. The condition often remains undiagnosed until adulthood when the genetic defect is discovered on investigation for other reasons as in this case of a young girl who presented with primary amenorrhoea. Cli...

BACKGROUND Women with congenital heart disease (CHD) may experience menstrual disturbances secondary to hemodynamic instability during the mensturation phase. OBJECTIVES We investigated the menstrual bleeding pattern and its relationship with certain clinical findings in adult women with CHD. PATIENTS AND METHODS Clinical data and menstrual bleeding pattern of adult women ≥15 years old who ...

BACKGROUND In this study, the characteristics of menstrual cycle in shift workers employed in the pharmaceutical industry are investigated. METHOD This study was conducted in a pharmaceutical industrial complex in Tehran in 2012. 406 female workers in packaging units were studied on the menstrual cycle characteristics. The studied workers were divided into two groups of shift workers and non-...

conclusions the stress due to psychosomatic changes in the menstrual cycle is associated with premenstrual syndrome. measures of s-iga, rather than cortisol or subjective responses to stress, may be most closely associated with pms. background several studies have demonstrated the associations between premenstrual syndrome and perceived stress, and no studies quantifying stress based on biochem...

[Purpose] This study investigated changes in the thickness of the transversus abdominis muscle at various stages of the menstrual cycle. [Subjects] The subjects were 15 young healthy females with regular menstrual cycles. [Methods] A regular menstrual cycle was defined as a 28-day cycle comprising 3 phases: the menstrual phase, the follicular phase, and the luteal phase. For the purpose of the ...

Hormonal fluctuations during the menstrual cycle may influence on muscular tensions and probably alter occlusal force. The aim of this study was to evaluate whether hormonal levels affect maximum occlusal force (MOF) of healthy women throughout the different phases of the menstrual cycle. Sixty complete dentate subjects who were not under use of oral contraceptives were selected to participate ...

Few studies exist on the physiological changes in the concentrations of growth hormone (GH), insulin-like growth factors (IGF) and IGF-binding proteins (IGFBP) within the menstrual cycle, and some controversy remains. We therefore decided to study the impact of endogenous sex steroids on the GH-IGF-IGFBP axis during the ovulatory menstrual cycle in 10 healthy women (aged 18-40 years). Blood sam...

BACKGROUND Sex hormones are known to regulate some responses during exercise. Evaluation of the differences in exercise response with regard to menstrual cycle will help understand the menstrual cycle phase specific adaptations to exercise and athletic performance. METHODS We investigated the effects of menstrual cycle phase and carbohydrate (CHO) ingestion on immune response during endurance...
