The human mammary gland is capable of de novo synthesis of glucose and galactose (hexoneogenesis); however, the carbon source is incompletely understood. In this study, we investigated the role of acetate, glutamine, lactate and glycerol as potential carbon sources for hexoneogenesis. Healthy breastfeeding women were studied following a 24-h fast on two occasions separated by 1-3 wk. Five women...

BACKGROUND The aim of this study is to determine the feasibility of using nuclear magnetic resonance (NMR) tracer studies ((13)C-enriched glucose) to detect ex vivo de novo metabolism in the perfusion fluid and cortical tissue of porcine kidneys during hypothermic machine perfusion (HMP). METHODS Porcine kidneys (n = 6) were subjected to 24 h of HMP using the Organ Recovery Systems LifePort K...

conclusions based on the findings, the mortality rate was 22.9% among poisoned patients with an elevated serum lactate level. we can conclude that mortality is associated with toxicants, but not the occurrence of vap; in fact, vap scenarios do not elevate serum lactate level. background lactate level is known to increase among the majority of patients with toxicity. this study aimed to determin...
