to evaluate the effectiveness of conjugated estrogen (premarin) and progesterone in twenty-one postmenopausal women who had been menopause one year, we tested during a 6-month period the serum lipoprotein levels in subjects who offered by premarin in dosage of 0.625 milligram for days 1 to 25 and oral medroxy progestrone acetste for days 15 to 25 of a 30-day cycle. twenty-one subjects completed...

conclusions the results suggest that physical activity improves metabolic parameters, which interfere in the development of fatty liver and has a protective role against the development of nafld. results statistical analysis demonstrated that the training group had significant changes in weight, bmi, tc, tg, ldl, vldl, hdl/ldl, tc/ hdl, ast and alt, whereas there was no significant change in hd...

The low density lipoprotein particle is the major transporter of cholesterol around the body and has been shown to be a strong independent risk factor for atherosclerotic events. This review discusses the normal and abnormal metabolism of low density lipoprotein (LDL). Mechanisms by which LDL causes atherosclerosis are discussed with particular reference to the importance of alteration in LDL c...

A child showed a type IIb lipoprotein pattern and triglyceride-enriched cutaneous xanthomas before 1 year of age. The proband and 9 of 18 relatives had elevated plasma levels of low density lipoprotein (LDL) B protein; of these nine relatives, four had elevated LDL of increased density while five had elevated LDL of normal density. Compared with normal LDL, LDL of increased density had less cho...

The association of plasma low density lipoproteins (LDL) with arterial proteoglycans (PG) is of key importance in LDL retention and modification in the artery wall. Lipoprotein lipase (LpL), the rate-limiting enzyme for hydrolysis of lipoprotein triglyceride, is known to bind both LDL and arterial PG. In the presence of LpL, cellular internalization and degradation of LDL is enhanced by a pathw...

background: urtica dioica has been used as antihypertensive, antihyperlipidemic and antidiabetic herbal medicine. the purpose of this study was to study the effect of hydroalcoholic extract of urtica dioica on fructose-induced insulin resistance rats. methods: forty male wistar rats were randomly divided into five groups including control, fructose, extract 50, extract 100 and extract 200. the ...

BACKGROUND Diabetes accelerates atherosclerosis through undefined molecular mechanisms. Hyperglycemia induces formation of advanced glycation end product (AGE)-modified low-density lipoprotein (LDL). Anti-AGE-LDL autoantibodies favor atherosclerosis (AS) progression in humans, while anti oxidized LDL immunization inhibits AS in hypercholesterolemic, non-diabetic mice. We here investigated if AG...

abstract   background: irregular working hours, including night work and shift work, have been found to be associated with alteration in various levels of biochemical factors. and some studies have showed association between shift work and blood biochemical disturbances in blood. in this epidemiological study we investigated, whether regular schedule of working hours can minimize the associated...

1. Phenobarbitone in a dose of 180 mg daily was administered to ten normal subjects for 3 weeks. There was a significant increase in total plasma cholesterol, plasma low-density-lipoprotein cholesterol, plasma low-density-lipoprotein (LDL) triglycerides and plasma LDL protein. The increase in plasma LDL cholesterol accounted for the increase in total plasma cholesterol. There was a significant ...
