Platelet Rich Plasma for Uterine Scar

When vessel wall injury occurs, platelets become activated, releasing more than 30 bioactive proteins, many of which have a fundamental role in hemostasis, inflammation and ultimate wound healing. Platelet-rich plasma (PRP), a modification of fibrin glue made from autologous blood, is being used to deliver growth factors in high concentration to sites requiring wound healing. PRP is obtained from a sample of patients' blood drawn at the time of treatment. As the rate of cesarean deliveries has been rising, long-term adverse sequelae due to uterine scar defects have been increasing. PRP might be a simple preventive treatment that potentially can reduce morbidity following cesarean deliveries.

Timing of Energy Availability on Menstrual Cycle Function

The primary aim of this clinical trial is to evaluate how fasted prolonged exercise may influence circulating reproductive hormones (i.e., estradiol, progesterone, luteinizing hormone) and menstrual cycle length when energy availability is maintained at or above 30 kcal/kg lean body mass/ day among women who regularly do running or cycling exercise. A secondary aim is to determine the effects of fasted prolonged exercise on serum leptin and cortisol. Participants will be asked to do the following over a \~3 month enrollment period: * attend a laboratory visit at the beginning of the study to have their resting metabolic rate, aerobic fitness, and body composition tested * monitor their menstrual cycle length, urine hormones, perceived stress levels, and diet for \~3 months * complete 3, 90-minute exercise sessions on a stationary bike or treadmill either fed (consuming a carbohydrate meal 1 h prior and 0.7 g carbohydrate/ kg body mass/ h during exercise) or fasted (consuming no meal prior and no carbohydrates during exercise) during month \~3 * saliva samples will be taken prior to and after 90-minute exercise sessions for quantification of leptin and cortisol

Sonographic Evaluation Of Uterine Fibroids At Different Locations In Patient With Irregular Menstrul Cycle

Uterine fibroids are a major cause of illness in women of a reproductive age. There are many factors involved in the growth and reduction of these common tumors. The most likely cause of fibroids is their effect on a woman's menstrual cycle. For accurate diagnosis numerous diagnostic markers on ultrasound are present which increases the efficacy of ultrasound to diagnose uterine fibroids.
