PTSD is a disorder of emotion dysregulation. Although much work has intended to elucidate the neural underpinnings of the disorder, much remains unknown about the neurobiological substrates of emotion dysregulation in PTSD. In order to assess the relationship between a neural measure of attention to emotion (i.e. the late positive potential; LPP) and PTSD symptoms, EEG was recorded and examined as a potential predictor of military-related PTSD symptoms in a sample of 73 OEF/OIF/OND veterans. Results revealed that higher PTSD symptoms were related to an attenuated LPP response to angry facial expressions...

This review aims to provide a historical reference of branched-chain amino acid (BCAA) metabolism and provide a link between peripheral and central nervous system (CNS) metabolism of BCAAs. Leucine, isoleucine, and valine (Leu, Ile, and Val) are unlike most other essential amino acids (AA), being transaminated initially in extrahepatic tissues, and requiring interorgan or intertissue shuttling for complete catabolism. Within the periphery, BCAAs are essential AAs and are required for protein synthesis, and are key nitrogen donors in the form of Glu, Gln, and Ala...

Population specific studies in prostate cancer (PCa) reveal a unique heterogeneous etiology. Various factors, such as genetics, environment and dietary regimen seems to determine disease progression, therapeutic resistance and rate of mortality. Enormous disparity documented in disease incidences, aggressiveness and mortality in PCa among AAs (African Americans) and CAs (Caucasian Americans) is attributed to the variations in genetics, epigenetics and their association with metabolism. Scientific and clinical evidences have revealed the influence of variations in Androgen Receptor (AR), RNAse L, macrophage scavenger receptor 1 (MRS1), androgen metabolism by cytochrome P450 3A4, differential regulation of microRNAs, epigenetic alterations and diet in racial disparity in PCa incidences and mortality...
