Erythromycin production is clearly enhanced by the addition of vegetable oils. However,whether this positive effect is brought about by the triglyceride or non-triglyceride fraction, isnot clear. The non-triglyceride portions of the oils accumulate in the waste during the refiningprocess leaving mainly triglycerides in the refined oil. In this research, sub-fractions of soybeanoil, including le...

The mechanisms behind the hypotriglyceridemic effect of 1,10-bis(carboxymethylthio)decane (3-thiadicarboxylic acid) and tetradecylthioacetic acid and the development of fatty liver caused by 3-tetradecylthiopropionic acid (Aarsland et al. 1989. J. Lipid Res. 30: 1711-1718.) were studied in the rat. Repeated administration of S-substituted non-beta-oxidizable fatty acid analogues to normolipidem...

This study tested the hypothesis that an acute infusion of beta-hydroxybutyrate inhibits myocardial fatty acid uptake and oxidation in vivo. Anesthetized pigs were untreated (n = 6) or treated with an intravenous infusion of fat emulsion (n = 7) to elevate plasma free fatty acid levels. A third group received fat emulsion plus an intravenous infusion of beta-hydroxybutyrate (25 micromol.kg-1.mi...

abstract alzheimer’s disease (ad) is the most common cause of dementia in elderly people. the prevalence of alzheimer diseases is increasing in the world due to population aging. metabolic disease such as diabetes and obesity play important role in alzheimer disease. hyperglycemia can play important role in brain damage. it causes cognitive impairments, functional and structural alterations in ...

Forty-two consecutive patients with acute myocardial infarction were studied over the first 3 days of their illness to determine the effect of oral or intravenous calorie intake on the circulating free fatty acid values. Repeated sampling in 9 patients showed that free fatty acid levels above 1000 mumol/l were seldom found beyond the first 10 hours after admission. Oral calories, chiefly in the...

In isolated hepatocytes prepared from unfed neonatal chicks, stimulation of fatty acid synthesis by fructose or dihydroxyacetone required acetate or octanoate in the medium, suggesting that the stimulatory effect of these compounds required the enhanced production of intramitochondrial acetyl coenzyme A. Stimulation of fatty acid synthesis by lactate or pyruvate did not require a supplementary ...

Over the last centuries, Western diets acquired a dramatic imbalance in the ratio of polyunsaturated fatty acids (PUFA) to saturated fatty acids (SFA) with a concomitant reduction in the dietary proportion of n-3 PUFA. Pastures are a good source of n-3 fatty acids, although the effect of forage intake in the fatty acid profile of meat from free-range chicken remains to be evaluated. In addition...

The free fatty acid and total fatty acid profiles in plasma of nine patients with medium-chain acyl-CoA dehydrogenase (MCAD) deficiency, two with very-long-chain acyl-CoA dehydrogenase (VLCAD) deficiency and two with mild-type multiple acyl-CoA dehydrogenase (MAD-m) deficiency, were analyzed by gas chromatography-mass spectrometry. In the plasma of patients with MCAD deficiency we found increas...

Ten patients with chronic effort angina and coronary artery disease (luminal diameter reduction greater than 75%) were stressed by atrial pacing (140 beats/minutes) before and 15 minutes after intravenous propranolol (mean dose 7.4 mg). Myocardial substrate exchange of oxygen, blood lactate, plasma free fatty acids, citrate, glucose, glutamate, and alanine as well as coronary sinus blood flow w...
