Variations in Ketone Metabolism
Recruiting
This outcome of this study will elucidate how the phenotype of the individual modulates the KE metabolic effect. Most studies of KE have been in homogenous populations, usually young, male athletes. However, two striking experiments using identical, body weight adjusted KE doses in healthy and obese individuals found that BHB area under the curve (AUC) and removal was reduced by obesity and poor metabolic health. Similarly, ketone infusion experiments found that diabetes, obesity, and insulin re... Read More

Sonocloud-9 in Association With Carboplatin Versus Standard-of-Care Chemotherapies (CCNU or TMZ) in Recurrent GBM
Recruiting
The brain is protected from any toxic or inflammatory molecule by the blood-brain barrier (BBB). This physical barrier is located at the level of the blood vessel walls. Because of these barrier properties, the blood vessels are also impermeable to the passage of therapeutic molecules from the blood to the brain. The development of effective treatments against glioblastoma is thus limited due to the BBB that prevents most drugs injected in the bloodstream from getting into brain tissue where the... Read More

Detection and Risk Stratification in Veterans Presenting With Microscopic Hematuria
Recruiting
It is of current debate whether the use of invasive (referring to a process that requires insertion into the body) standard of care procedures such as a cystoscopy which is a procedure to look inside the bladder using a thin camera called a cystoscope, is appropriate for use in patients with microscopic hematuria or blood in urine invisible to the naked eye. This is because the risk of disease (bladder cancer - urothelial carcinoma) is relatively low in this population group, approximately 3%. I... Read More

Platelet Rich Plasma Testis Treatment for Infertile Men
Recruiting
Investigate the effect of intratesticular injection of autologous platelet rich plasma (PRP) on sperm retrieval rates and IVF outcomes in infertile men who already underwent a negative sperm retrieval. Currently, there is no alternative treatment after failed TESE. Prior series suggest that intratesticular PRP injections may improve TESE outcomes. We hope to determine whether PRP is an effective treatment for this patient population.

Kaiser Permanente houses over 6,000 physicians in southern California and it is also one of the largest research centers on the state. On its clinical trial division, Kaiser Permanente conducts clinical trials of almost every specialty funded by pharmaceutical companies, government, and foundations.
The Cedars-Sinai Medical Center located in Los Angeles is one of the largest research centers owned and operated by a private hospital in the United States. Focusing on biomedical, cancer, and heart research among other specialties, you can find almost any type of clinical trials for both health and non-healthy volunteers at the research division of Cedar-Sinai Medical Center.
There are around 100,000 clinical trials happening every year across the United States about almost every condition out there. While most clinical trials are testing drugs or medical devices there are also many behavioral and observational trials going on at any point in time. Many paid research studies are held at these California locations.
Clinical trials are incredibly important for making new medical and scientific discoveries, finding new and better methods for diagnosing medical conditions early, testing new interventions, and even developing safer and more effective surgical procedures.
In order for all these discoveries to me made available to the general population they need to go through years of rigorous testing both in healthy and non-healthy volunteers. During those years, medical professionals follow a protocol that has been previously approved by the FDA or other regulatory agency to test the effectiveness and safety of their discovery.
Other people choose to participate in a clinical trial because they feel it is a good way to contribute to the advancement of medical knowledge and that their participation can help many people in the future.
