10 Clinical Trials for Various Conditions
Participation will take place over two visits to the Clinical Exercise Research Center (CERC) at the University of Southern California Health Sciences Campus. On the first visit, height, weight, and body composition by bioelectrical impedance are recorded. Questionnaires and withdrawal of a sample of blood (1 tablespoon) are also completed. The intervention begins the day following the first visit. The intervention protocol consists of three weeks of consuming either a placebo capsule or a 5000 IU Vitamin D capsule daily and completing a daily survey. The second visit to CERC immediately follows the 3-weeks intervention. In this visit, the same blood sampling protocol will be completed. The assignment of the intervention will be randomized (i.e., rolling a die), and participants are blinded to group assignment.
This study will examine how the supplement Shroom Tech Sport (STS) affects body composition and different performance and health measures over the course of 12 weeks. The supplement will be combined with a concurrent training regime consisting of resistance and high intensity interval training. Subjects will be tested for percent body fat to determine body composition. Further, they will also be tested for maximal strength (squat and bench), maximal power output and fatigue, lactate threshold and maximal oxygen volume consumption (VO2max). And finally, subjects will be tested for health and hormone markers in the blood. All of these measures will be compared against a placebo group participating in the same exercise intervention.
The purpose of this study is to compare gene expression profiles in endometrial biopsies during the window of implantation after triggers of oocyte maturation using GnRH agonist or hCG and compared with their natural cycles in order to identify genes that may be dysregulated in GnRH agonist-triggered cycles. The investigators also intend to evaluate patients feeling of well being and physical quality of life after GnRH agonist trigger compared with hCG trigger.
In this study we tested the hypothesis that an increase in protein content of the diet will result in an increase in the 24-hour integrated circulating growth hormone (GH) and insulin-like growth factor-1 (IGF-1) concentrations and an increase in lean body mass in people with untreated type 2 diabetes.
This study will examine markers of vascular endothelial function (vascular health) and metabolic profiles in older versus younger transgender men (people who were assigned female at birth but whose gender identity is male). Data will also be compared to those from age group-matched transgender women and cisgender women and men.
The investigators would like to study the genetic and molecular outcomes that results after a short term neoadjuvant hormonal therapy on patients with breast cancer.
This study will examine markers of vascular endothelial function (vascular health) and metabolic profiles in younger versus older transgender women (people who were assigned male at birth but whose gender identity is female). Data will also be compared to those from cisgender women and men.
(A) Major 1) to compare the effectiveness of norethindrone acetate (NA) with GnRH agonist (Lupron-Depot-3) in relieving symptoms of endometriosis, 2) to compare bone density in the two treated groups in order to demonstrate that NA does not affect bone density; (B) Minor: 1) To compare the lipid profiles of patients in the two groups to confirm the hypothesis that the effects of NA and GnRH agonists on lipid profiles are similar, 2) To determine whether quality of life, assessed by questionnaire, is better in patients assigned to NA than in patients assigned to GnRH, 3) To determine whether NA has fewer adverse effects than GnRH agonist.
The purpose of this study is to determine whether testosterone plus finasteride treatment will improve musculoskeletal health, neuromuscular function, body composition, and metabolic health in hypogonadal men who have experienced ambulatory dysfunction subsequent to incomplete spinal cord injury. The investigators hypothesize that this treatment will improve bone mineral density, enhance muscle size and muscle function, and improve body composition, without causing prostate enlargement.
This is a phase II multi-center study to determine the clinical impact of using a patient-specific genomic expression signature of androgen receptor (AR) activity to determine therapy for patients with castration-resistant metastatic prostate cancer (CRPC). After patient eligibility is determined, the genomic signature will be applied to fresh frozen tissue harvested from a metastatic lesion during image-guided biopsy. After assessing for androgen receptor activity, the investigators will select patients for either continued androgen manipulation with nilutamide (high AR activity) or targeted therapy with dasatinib (low AR activity). Once patients develop a first progression on either arm, patients will receive combination therapy with dasatinib and nilutamide. The primary aim is to estimate the median progression free survival in men with CRPC treated according to tumor AR activity. The investigators hypothesize that by treating men based upon AR activity, median progression free survival (PFS) will improve from a historical median of 3.0 months to 6.0 months.
