...Jennifer J. Hamilton; Nancy Auestad; Sheila M. Innis The reason why plasma cholesterol levels increase soon after birth is unknown but may be related to change rates of cholesterol synthesis and/or expression of LDL receptors. Plasma cholesterol levels, along with hepatic HMG CoA reductase activity...

... infants who did not receive diuretics. Plasma triglycerides, total cholesterol and high-density lipoprotein (HDL) cholesterol were measured enzymatically prior to onset of diuretic therapy in the study group of infants and on the day of recruitment into the study in control infants, and every 2 weeks...

... a rise in plasma cholesterol and a decrease in hepatic 3-hydroxy-3-methylglutaryl CoA reductase activity in infant but not in weaned animals. The activity of acylcholesterol acyl CoA transferase, on the other hand, was decreased after drug administration. Thus, both antihypertensive drugs may cause...

...P. Hahn; L. Srubiski Wistar rats were weaned on day 18 to a high fat (HF), high carbohydrate (HG) or high cholesterol (HCO 2%) diet. The activities of 3-hydroxy-3-methylglutaryl-CoA-reductase (HMGR), 7α-hydroxylase (7-OHase) and acyl-CoA-cholesterol-acyltransferase (ACAT) were assayed in the liver...

... in any other tissue, while in the 22-day-old rats, this is no longer the case. Cholesterol synthesis in the oldest age group was highest in liver. In the younger animals, there was little difference between tissues in the low rate of cholesterol synthesis except in the brain where the rates of all lipid...

... and diabetic animals and consider possible effects on fetal growth and development in normal and diabetic pregnancy. The concentration of all lipoprotein fractions increases during pregnancy. VLDL cholesterol and triglyceride increase 2.5-fold over prepregnancy levels and LDL cholesterol increases 1.6-fold...

...Walsh Hentges; R.J. Martin Serum and lipoprotein (LP) lipids were measured in fetal pigs and their dams during gestation. In the 2nd trimester (70 days of gestation), fetal lipids resembled those of their dams. Early in the 3rd trimester (90 days) total serum concentrations of cholesterol (CH...

...Lynnette S. Walsh Hentges; Amy C. Williams; William A. Mangham; Roy J. Martin Serum and lipoprotein lipids were quantified in pregnant and nonpregnant sows allowed restricted and ad libitum access to a low-fat cholesterol-free diet, and in the progeny of these sows. Pregnant sows exhibited a mild...

...S.M. Innis; N.C. Haave Diet-induced elevation of cholesterol and corticosterone in pregnant rats had no effect on fetal plasma cholesterol or corticosterone, 3-hydroxy-3-methylglutaryl coenzyme A or hepatic reductase activities. The data suggest that increasing the maternal cholesterol pool has...

...M. Dobiášová; F. Stožický; J. Kopecká Changes in the rate of plasma cholesterol esterification occurring shortly after birth were followed by determining the activity of lecithin-cholesterol acyltransferase (EC 2.3.1.43) in newborn children, and at the age of 3 days and 3 months. The radioassay...

...Michal Palkovič; Nina Škottová; Anna Hoštacká In young rats reared with their mothers, a gradual increase of serum cholesterol, triglycerides, phospholipids and total lipids was found between the 7th and the 18th to 22nd postnatal day. Then the concentrations of lipids gradually decrease. Early...

..., the lipoprotein pattern was dominated by LDL (β-lipoprotein). Fetal HDL (α-lipoprotein) occurred at a low concentration and showed a lower proportion of cholesterol and a higher proportion of triglycerides than did HDL in the adult rat serum. VLDL (pre-β-lipoprotein) was present only at very low concentrations...

... quantitative changes during development. After the onset of colostrum ingestion, a lipid-stainable zone appeared in the γ-region of piglet’s serum and sow colostrum/milk. The levels of total serum lipids, cholesterol, high and low density lipoproteins were low at birth in comparison to those of the adult pig...

Wallace The patterns of plasma concentrations of thyroxine (T 4 ), triiodothyronine (T 3 ) and cholesterol were determined in tropically adapted (ZX) and temperate (SH) breeds of cattle in the first 6 days of their lives in a tropical environment. T 4 concentrations were high...
