The study investigates the explanation for the positive relation found between exercise and breastcancer.

The main purpose of this study is to detect the frequency response in the electric wave transmission through the channels inside human body. With the electric signals in different frequencies, analyzed by the digital signal processing technique, the adaptability of the channel for different frequencies may be revealed. With this study there will be a feasible connection between the physiological signals and the channel theory in Chinese medicine, and the basis of the physiological signals can be drew out for the description of the internal organs, the strong or weak, the truth or falsity. The Zu-San-Li is the open acupoint on foot-Yangming channel, the stomach channel. Qi, the main concept in TCM, will flow from the open acupoint to go into deep internal organs. Xian-Gu is another Yu acupoint on foot-Yangming channel. The inborn original Qi flows from the Yu acupoint infuse into blood vessels. So in this study the investigators will take these two acupoints for the acupuncture. Since the direction of the channel is from Zu-San-Li to Xian-Gu, the investigators pick Zu-San-Li as the input and Xian-Gu the output for the electrical signals. For this experiment, the investigators planned enrolling 30 male sub-healthy volunteers, aged in 20-35 years old, to finish the whole experiment procedures. After the acupuncture, the electric signals of different modes will be input from the subject's open acupoint (Zu-San-Li), and measure the frequency respond voltage from the output acupoint (Xian-Gu). Each subject must complete the acupuncture of Zu-San-Li and Xian-Gu, and be input 5 sets of the electric signals of different modes two times on the trial. The variety conditions of the wave form and electric voltage will be recorded and measured respectively. The investigators plan to obtain the data in six months, and complete the data analysis and sorting in two months.

This is a comparison of the functional results and Varus-Valgus Stability in Single-radius versus Multi-radius Femoral Component for Total Knee Arthroplasty.

The aims of this study are to (1) understand the uncertainty , personality and coping strategies in patients with HCC, and identify the significant factors for coping.

The patients will be submited to a vaginal squeeze pressure measurements before and after surgeries for urinary incontinence.

To validate a new method for assessing perioperative risk in the cancer patient undergoing major cancer surgery. In this proposed study researchers will: Measure preoperative energy reserve capacity (fitness) Determine if postoperative morbidity is a function of perioperative cardiopulmonary gas exchange metabolism

The primary purpose is to test intersubject variability and establish the qualitative features of normal VRI images and the range of normality of the VRI quantitative lung data values that may be used to differentiate normal from abnormal breath sound distribution. Our hypothesis was that VRI breath sound images of healthy subjects are similar in a qualitative and quantitative manner.

This study will have significant impact on muscular dystrophy patients as it promotes early screening for heart disease. With early identification, beneficial medical therapy can be started sooner, resulting in restoring and maintaining normal heart function. This is critical to the survival of these patients. We have reported previously that heart failure in all patients may have common mechanisms, the "final common pathway". Heart failure is a significant health problem with 5 million people in the US carrying the diagnosis and accounting for 12-15 million office visits and 6.5 million hospital days per year. The number of deaths from heart failure continues to increase. The data from this study could impact patients worldwide with heart failure by offering new insight into an ever-growing disease population and lead to significant changes in how they are currently treated.

We use multiphoton laser scanning microscopy to observe cutaneous anatomy and pathology. The study aims to compare surgical specimen by conventional pathology slice with the image by non-invasive multiphoton laser scanning microscopy.

Any time the words "you," "your," "I," or "me" appear, it is meant to apply to the potential participant. The goal of this laboratory research study is to collect and store blood and tissue from patients who have a diagnosis of heart disease and may be at a high risk for the development of heart failure. This blood may be used in the future to identify genes that may play a role in developing congestive heart failure (CHF) from chemotherapy or other sources. This is an investigational study. All will be enrolled at MD Anderson.
