the prevalence of sub-clinical ketosis and its predisposing factors were assessed in three dairy farms with different sizes (large, medium, small) and different facilities, and with constant management routines. eighty-one cows within the first two months of lactation were sampled for blood. the concentrations of beta-hydroxybutyrate and glucose were determined in blood serum. rations were anal...

Pseudomonas resinovorans produced poly-beta-hydroxyalkanoates (PHAs) when grown on hydrocarbons but not on glucose. In a chemostat culture, the PHA composition was beta-hydroxybutyrate (C4)-beta-hydroxyhexanoate (C6)-beta-hydroxyoctanoate (C8)-beta-hydroxydecanoate (C10) (1:15:75:9) on octanoate and C4-C6-C8-C10 (8:62:23:7) on hexanoic acid. Contrary to the reported behavior of Pseudomonas oleo...

BACKGROUND Ketogenic diets are used therapeutically to treat intractable seizures. Clinically, it appears that the maintenance of ketosis is crucial to the efficacy of the diet in ameliorating seizures. To understand how ketosis and seizure protection are related, a reliable, noninvasive measure of ketosis that can be performed frequently with minimal discomfort is needed. OBJECTIVE The objec...

OBJECTIVE We examined whether ingestion of medium-chain triglycerides could improve cognition during hypoglycemia in subjects with intensively treated type 1 diabetes and assessed potential underlying mechanisms by testing the effect of beta-hydroxybutyrate and octanoate on rat hippocampal synaptic transmission during exposure to low glucose. RESEARCH DESIGN AND METHODS A total of 11 intensiv...

A 25-year-old man with a past medical history of type 1 diabetes presented to the emergency department 2 days progressive abdominal pain, nausea, and vomiting after stopping insulin. His heart rate was 125 respiratory 26. The glucose 832 mg/dl, potassium 6.6 mmol/L, beta-hydroxybutyrate 111.8 pH 6.95.
