Heart failure (HF) patients are a medically complex and heterogeneous population with multiple cardiac and non-cardiac comorbidities. Although there are a multitude of etiologic substrates and initiating and amplifying mechanisms contributing to disease progression, these pathophysiologic processes ultimately all lead

Biologically inert material in feces may confound interpretations of noninvasive fecal endocrine data, because it may induce variance related to differences in foraging behavior rather than to differences in endocrine activity. We evaluated two different enzyme immunoassays (EIAs) for the

17-Hydroxyprogesterone (17-OHP) can be converted to dihydrotestosterone (DHT) via an alternative "backdoor" route that bypasses the conventional intermediates androstenedione and testosterone. In this backdoor pathway, 17-OHP is converted to 5α-pregnane-3α,17α-diol-20-one (pdiol), which is an excellent substrate for the 17,20 lyase
