1. Human erythrocyte membrane cholesterol, fluidity and basal and calmodulin-stimulated calcium pump (Ca(2+)-Mg(2+)-ATPase) activities were compared in 24 patients with primary combined hyperlipidaemia and 20 age-matched normolipidaemic control subjects. 2. There was no correlation between serum and membrane cholesterol. Despite the differences in serum cholesterol levels between the two groups...

Potatoes (Solanum tuberosum) contain α-solanine and α-chaconine, two well-known toxic steroidal glycoalkaloids (SGAs). Sprouts and green tubers accumulate especially high levels of SGAs. Although SGAs were proposed to be biosynthesized from cholesterol, the biosynthetic pathway for plant cholesterol is poorly understood. Here, we identify sterol side chain reductase 2 (SSR2) from potato as a ke...

Concentrations of total cholesterol and cholesterol in the various lipoprotein fractions were measured in vegans, vegetarians, fish eaters (who did not eat meat), and meat eaters. Total and low density lipoprotein cholesterol concentrations were higher in meat eaters than vegans, with vegetarians and fish eaters having intermediate and similar values. High density lipoprotein cholesterol concen...

probiotic products highly affect the health of consumers by reducing the risk of heart attacks and improving the desirable microflora in the intestinal tract. in this study the effect of yogurt (500g/d for 3 wk) enriched with either bifidobacterium bifidum or lactobacillus acidophilus on the level of cholesterol, low density lipoprotein (ldl) and high density lipoprotein (hdl) of serum and ...

the relationship between blood physiological attributes and carcass characteristics wasstudied in 40 randomly selected 8-month-old ram lambs of ghezel and mehraban (20 rams per breed)sheep. one day before slaughter, blood samples were obtained after a 24 hr fast. serum samples wereassayed for glucose, cholesterol, serum urea nitrogen (sun), total protein, albumin, triglycerides,creatinine, and ...

A 3 × 2 factorial arrangements with completely randomized design, with a total of 72 Leghorn Hy-line (W-36) laying hens in the second cycle (98 wk old) of production were randomly assigned to 24 wire cages (45.7×30×30 cm3) and fed with diets containing three levels of guar meal (GM; 0, 4 and 8%) and two levels of β-mannanase (Hemicell®) enzyme (0.00 and 0.05%) for 12 wk period. There...

The current studies indicate that Leydig cells from old (24-27-Mo) rats secreted significantly less cholesterol in response to stimulators, hCG, forskolin, or Bt2cAMP as compared to cells from young mature (5-Mo) animals. This deficiency was reversed by incubation of cells with free diffusible hydroxycholesterols, indicating that age-related decline in testosterone secretion primarily results f...

Flaxseed oil has various benefits over multiple chronic diseases in humans and animals. Besides, flaxseed shown the potential to avert lipid disorders. However, researches have indicated that lower serum cholesterol animals human beings can be attributed whole oil. Therefore, this study aimed at determining effect of different levels on biochemical changes hypercholesterolemic rats. In study, (...

In order to study the biosynthesis, composition, and origin of sterols in the Florida land crabs, Cardisoma guanhumi (Latreille), we fed 17 male crabs either a cholesterol-free or a high cholesterol diet for 2 to 7 weeks. The origin of sterols in these crabs, whether from biosynthesis or from the diet, was determined by tahree procedures: the incorporation of isotopic mevalonate into the choles...
