Performance and Cognitive Changes Across Menstrual Phase
This study will look at the influence of the hormonal changes that occur between the early-follicular and mid-luteal phases of the menstrual cycle on neurocognitive performance before and after an intense resistance workout in premenopausal, moderately active females. Additionally, this study will be determining the accuracy and usefulness of using a menstrual cycle tracking phone application in predicting menstruation and ovulation

Hepatitis C Virus Immunity in Women and Children
This is a study to find out how pregnancy affects a mother’s immune system. (The “immune system” is the part of the body that fights germs.) This study is also to find out why some babies who are exposed to infections during pregnancy get infected and others do not.
To do this project we need to study some women and babies who are infected with the hepatitis C virus and others who are not. This will allow us to compare their immune systems.
You may be eligible to participate if you are:

A Study for New Moms about Pelvic Floor Disorders
The goal of this study is to learn more about problems with urine or stool control, prolapse (feeling or seeing a vaginal bulge), and pain with sex, all which can affect mothers after delivery when they are most busy with their newborn.
If you join this study, you will complete a series of online surveys over a period of 12 months. The surveys will ask about urine and stool control, pelvic issues, and sexual issues. Each survey will take about 5-10 minutes.

A Resistance Training Study for Postmenopausal Women Ages 40-75
The primary aim of this study is to determine the effects of resistance exercise intensity on inflammatory markers and psychosocial response in postmenopausal women. Inflammation is part of your body’s immune response to various stimuli and is the body’s way of protecting itself from damage. It’s important to measure inflammation to determine the response to exercise. In this study, we aim to measure inflammation in the blood (what are called inflammatory markers) in response to three different resistance exercise intensities.
You may be eligible for this study if you are:
• Female, ages 40-75
• Postmenopausal (as diagnosed by a physician)
• Overweight (BMI >25 kg/m2)
• Physically capable to perform regular physical activity
• Recreationally trained (regular resistance exercise participation 2 times per week for the past 6 months)
