Sodium acetate C-11 (C-11 acetate) Injection is a radiopharmaceutical commonly used for clinical studies with positron emission tomography (PET). It is used as a PET radiotracer for imaging cancer cells via incorporation into intracellular phosphatidylcholine membrane microdomains in cancer cells. Positron emission tomography using carbon-11 acetate (AC-PET) may help find local or distant metastases from prostate cancer. C-11 acetate is taken up in proportion to fatty acid synthesis. It is also taken up proportionally to myocardial blood flow, and therefore myocardial oxygen consumption. In rodents, there is clearance from all organs except the pancreas within one hour. Tumor uptake was clearly visible in 30 minutes. In humans, more than 80% of tracer is cleared from normal tissues within 20 minutes.It is taken up in cancer within the prostate and prostate cancer metastases, however, it has been reported that increased uptake can be seen in hyperplastic and benign prostate tissues. No urinary excretion is seen. No toxic effects have been demonstrated. The ongoing clinical trial NCT01530269 is studying how this imaging test may help influence the choice and extent of initial treatments, and subsequent treatments of prostate cancer.

Fulvic acid is primarily studied for its effects on plants and soil. Fulvic acid is an organic and natural electrolyte. Depending on the situation, Fulvic acid can act as an electron donor or acceptor and an oxidizer or reducer. Fulvic acid has exhibited the ability to enhance the availability and adsorption of nutrients as well as prolong their time of residence. In the chick animal model Fulvic acid disturbed the processing of procollagen II in articular cartilage. Fulvic acid has being shown to attenuate homocysteine-induced cyclooxygenase-2 expression in human monocytes. Fulvic acid, the main active principle of Shilajit (a natural substance found mainly in the Himalayas), blocks tau self-aggregation, opening an avenue toward the study of Alzheimer's therapy. People take fulvic acid by mouth for brain disorders such as Alzheimer’s disease, as well as respiratory tract infections, cancer, fatigue, heavy metal toxicity, and preventing a condition in which the body tissues do not receive enough oxygen (hypoxia).
