hypothyroidism/triacylglycerol

1. Adipocytes were isolated from the interscapular brown fat and the epididymal white fat of normal, streptozotocin-diabetic and hypothyroid rats. 2. Measurements were made of the maximum rate of triacylglycerol synthesis by monitoring the incorporation of [U-14C]glucose into acylglycerol glycerol

Methimazole-treated hypothyroid rats were injected intravenously with triacylglycerol/cholesteryl oleate/cholesterol/phospholipid emulsions designed to model the composition of chylomicrons. Compared with controls, hypothyroidism decreased the clearance rates of emulsion cholesteryl oleate.

1. Induction of hypothyroidism in rats by feeding propylthiouracil (PTU) significantly increased serum cholesterol concentrations, and the effect was more pronounced for cholesterol in low-density lipoproteins (LDL) rather than high-density lipoproteins (HDL). The concentrations of serum

The activity of cholesteryl ester transfer protein is instrumental in the distribution of cholesteryl ester between lipoproteins in plasma. We measured the activity of cholesteryl ester transfer protein in plasma, designated cholesteryl ester transfer activity, as the rate of cholesteryl ester

The influence of thyroidectomy on the lipid composition of caput and cauda epididymides have been studied. The analysis was conducted in epididymal tissues free from fluids and sperm. A general tendency towards accumulation of epididymal lipids was observed in hypothyroid rats. Hypothyroidism also

Male Sprague-Dawley rats were treated for up to 4 weeks with propylthiouracil in a study designed to determine the effects of experimental hypothyroidism on plasma lipoproteins. The distribution of lipid constituents across the plasma lipoprotein spectrum was assessed by size exclusion

Dyslipidaemia and hyperglycaemia are associated with ovarian failure and both have been related to hypothyroidism. Hypothyroidism promotes anovulation and ovarian cysts in women and reduces the size of follicles and the expression of aromatase in the ovary of rabbits. Considering that ovarian

Impaired thyroid function-hypothyroidism, is associated with changes in the spectrum of serum lipids. Thyroid hormones increase the number and activity of LDL receptors in the liver and peripheral tissues and have also a direct impact on the triacylglycerol synthesis in the liver. If their amount in

BACKGROUND Thyroid hormones are well known modulators of signal transduction. The effect of hyper- and hypo-thyroidism on diacylglycerol/protein kinase C (DAG/PKC) signaling in cardiomiocytes has been determined. Triiodothyronine (T3) has been shown to prevent the alpha1-adrenoreceptor-mediated

Rat serum VLDL, unlike human, contains significant proportions of triacylglycerols with polyunsaturated C20 and C22 fatty acids. Hypothyroidism in this species is characterized by low levels of serum VLDL, the accumulation of LDL, elevated levels of lipoprotein lipase and depressed hepatic lipase

1. The metabolism of glucose and glutamine was studied in the small intestine and the colon of rats after 4-5 weeks of hypothyroidism. 2. Hypothyroidism resulted in increases in the plasma concentrations of ketone bodies (P less than 0.05), cholesterol (P less than 0.001) and urea (P less than

Hypothyroidism affects the content of triacylglycerol (TAG), total cholesterol (TC), oxidized lipids, glycogen, and infiltration of immune cells into the ovary and uterus. This study aimed to analyze the impact of hypothyroidism on the lipid content of different regions of the oviduct. Control (n =

1. Liver from hyper- and hypo-thyroid male fed rats were perfused with whole blood and their metabolism was compared with euthyroid controls. 2. Hyperthyroid livers produced more bile than controls and hypothyroid livers produced less. 3. Glucose output by all livers was similar; glycogen declined

The concentrations of serum lipids (total cholesterol, triacylglycerols), apolipoprotein B and thyroid hormones (thyroxine, triiodthyronine) were observed before and during hormone replacement therapy by thyroid hormones in 24 hypothyroid patients (18 women and 6 men) until the state of euthyroidism

1. The present study was conducted to examine the effects of α-lipoic acid on hypothyroidism-induced negative growth performance and whether α-lipoic acid alleviates acute heat stress in relation to hypothyroid status. 2. Female broiler chickens (14 d-old) were fed diets supplemented with α-lipoic
