...Juliana Saín; Marcela A. González; Arrate Lasa; María Victoria Scalerandi; Claudio A. Bernal; Maria P. Portillo Aim: Our aim was to investigate the effects of trans -fatty acids (TFA) on liver lipid metabolism in mice fed on experimental diets rich in either oleic or linoleic acid. Methods: Twenty...

... their life span. Samples of abdominal adipose tissue, liver and plasma were collected to determine fatty acid profile and fasting glycemia. Morphometric analysis of the liver and hepatosomatic index determination were conducted. Deposition of TFA was observed in the liver, adipose tissue and plasma of IP-TFA...

...Julia Spielmann; Anne Noatsch; Corinna Brandsch; Gabriele I. Stangl; Klaus Eder Background: It has been hypothesized that the arginine:lysine ratio of dietary proteins influences cholesterol concentrations in plasma and liver of men and animals. This study was performed to test this hypothesis...

... to the high-fruit intake, the level of cholesteryl esters was reduced in the liver, and hepatic ACAT activity, determined in vitro under various conditions of incubation, was lowered by about 30%. Moreover, plasma cholesterol was redistributed among the lipoproteins, with a decrease in the cholesterol...

...P. Bobek; L. Kuniak; L. Ozdín In male rats fed a diet containing 1.5% cholesterol and 5% of dried mushroom (Pleurotus ostreatus) a significantly reduced accumulation of cholesterol in serum (by 45%) and the liver (by 15%) was observed at the end of the 12th week of the experiment. The decrease...

... fed a diet containing 10% fish oil for 3 months to reduce Δ6D activity. After this period, some of the animals were killed. The other animals were returned to the original diet deficient in α-linolenic acid. Fatty acid composition in liver and brain and hepatic Δ6D activity were analysed 3 and 7 days...

... such variations are due to differences in lipogenic enzyme activities or to other factors. The aim of the present study was to compare the lipogenic activities of tissues from different sites (Longissimus dorsi muscle, liver, subcutaneous backfat) and between the outer and inner backfat layers. The effects...

...M. Holeček; F. Skopec; L. Šprongl This paper evaluates the role of decreased food intake in protein metabolism in cirrhotic animals by comparing the changes with those observed in pair-fed controls. Rats were injected with [ 14 C]leucine and then divided into 3 groups. Liver cirrhosis was induced...

...Emile A.M. de Deckere; Willem J. Kloots; Carla J. van Bemmel Generally, the rate of hepatic de novo fatty acid (FA) synthesis (lipogenesis) in vivo is determined by measuring the amount of newly synthesized FA present in the liver 1 h or less after injection of label ( 3 H 2 O) for FA synthesis (1...

... intake, a level that we have previously shown to be both necessary and sufficient to satisfy the requirements of the brain for fatty acids of the n-3 series. In the liver, the intermediary metabolism ensures an important release of long-chain polyunsaturated fatty acids, which may help to satisfy...

... in the liver. These changes were accompanied by liver-specific stimulation of methionine adenosyltransferase and reduction of spermine synthase activities. Inadequate arginine feeding or supplementation of the diets with ornithine or excess arginine resulted in no apparent changes in tissue methionine...

...S.C. Cunnane; M·S. Manku; D.F. Horrobin In choice situations, the golden Syrian hamster shows a strong preference to drink an ethanol solution to water alone. Because of the known effects of ethanol on lipid metabolism, its effects on liver fatty acids were therefore studied in the hamster. After...

... using tritiated glucose and an euglycemic glucose clamp were performed to measure the glucose production rate and peripheral insulin sensitivity, respectively. Two groups of recently abstinent chronic male alcoholic patients without evidence of liver damage were studied. The glucose turnover technique...

... day of age. At 28th day of age, study of the gastrocnemius muscle revealed significantly greater organ weight, protein, DNA and RNA contents, protein/DNA and RNA/DNA ratios in group 2 and 3 pups than in controls. In the liver, whereas all these indices were significantly increased in group 3 pups...

...P. Bobek; E. Ginter; M. Jurčovičová; L. Kuniak We studied the effect of the edible mushroom Pleurotus ostreatus (4% in diet containing 1 % of cholesterol) on serum and liver lipids in female rats with hereditary enhanced sensitivity to alimentary cholesterol. We found that the consumption...

...B. Rousson; M. Leclercq; M. Bourgeay-Causse; G. Pérès; J. Jouanneteau In growing rats, an increase in ambiant temperature from 25 to 34 °C decreased the level of vitamin A by 54% in plasma and 17% in the liver. But the quantity of vitamin A available for the organism (quantity per gram body weight...

...J.P. Carreau; D. Lapous; J. Raulin 6-day-old suckling rats, born to females kept on a fat-free diet, were used to determine cholesterol and fatty acid specific radioactivity (SRA) in the liver, kidneys and brain, after injection of 3 µCi uniformly 14 C-labeled linoleic acid (ULI) or oleic acid (UOL...
