Chylomicrons play a role in atherosclerosis, however, because the mechanisms involved in the cell uptake of these particles are not fully understood, investigations were carried out using a radioactively labeled protein-free triacylglycerol-rich emulsion incubated with peritoneal macrophages
The link between raised levels of LDL (low-density lipoprotein) cholesterol in the blood and atherosclerosis is incontrovertible. The situation with regard to TRLs (triacylglycerol-rich lipoproteins) is not as clear. Nevertheless, there is substantial evidence that TRLs may in some cases be just as
The etiology of the hypertriglyceridemia in alloxan-diabetic rabbits was studied by two independent methods. Production and removal rates of VLDL triacylglycerol were measured in diabetic rabbits by injection of [3H]palmitate-labelled VLDL. Similarly, triacylglycerol total removal rates were
In eukaryotes, S-adenosyl-L-homocysteine hydrolase (Sah1) offers a single way for degradation of S-adenosyl-L-homocysteine, a product and potent competitive inhibitor of S-adenosyl-L-methionine (AdoMet)-dependent methyltransferases. De novo phosphatidylcholine (PC) synthesis requires three
BACKGROUND
Lipid-enriched diets and oxidative stress are risk factors for the development of atherosclerosis. The effects of the methanolic (ME) and cyclohexane (CHE) extracts of the Pistacia vera nut, often included in the Mediterranean diet, were studied in the rabbit model of
OBJECTIVE
CD36 is expressed on multiple cell types and has numerous functions, a subset of which can impact on atherogenesis. In previous work, we demonstrated that CD36 absence was protective against lesion formation. The current objective was to determine whether absence of macrophage CD36 alone
Functional food represents an important alternative management of atherosclerosis, its risk factors, and clinical complications. Atherosclerosis is characterized by microinflammation, formation of atheromatous lipoprotein-rich plaques, and protrombogenic status. Cornelian cherry (Cornus mas
The accurate spatial distribution of various lipid species during atherogenesis has remained unexplored. Herein, we used time-of-flight secondary ion mass spectrometry (TOF-SIMS) to analyze the lipid distribution in human coronary artery cryosections. The images from the TOF-SIMS allowed
BACKGROUND
Hitherto published experimental and clinical studies provide controversial findings as regards the relations of risk factors of atherogenesis and ischaemic heart disease and variations of body weight. The objective of the present study was to find out whether variations of body weight in
Elevated plasma homocysteine is a risk factor for atherosclerotic disease. In the present study, we have examined whether the oxidative stress due to a low level of vitamin B6 accelerates the development of homocysteine-induced atherosclerosis in rats. First, the effect of homocysteine thiolactone
UNASSIGNED
Analysis of the correlation between diabetes type 2 (DT2) and serum N-acetyl-β-hexosaminidase (HEX) activity with parameters of fat metabolism and symptoms of anxiety and depression.
UNASSIGNED
The study was performed using a random sample of 40 DT2 patients (22 women and 18 men) between
The ability to store energy in the form of energy-dense TAG (triacylglycerol) and to mobilize these stores rapidly during times of low carbohydrate availability (fasting or famine) or during heightened metabolic demand (exercise or cold-stress) is a highly conserved process essential for survival.
Vitamin E is the term used for eight naturally occurring fat-soluble nutrients. Alpha-tocopherol predominates in many species and has the highest biological activity. Vitamin E is absorbed via the lymphatic pathway and transported in association with CM. Vitamin E is carried in plasma by
Dysfunction of the melanocortin system can result in severe obesity accompanied with dyslipidemia and symptoms of the metabolic syndrome but the effect on vascular atherogenesis is not known. To study the impact of obesity and dyslipidemia on the cardiovascular system, we generated mice
The Japanese quail has been used as a model of human atherosclerosis to investigate the mechanisms underlying the development of vascular lesions, i.e. hyperlipoproteinaemia and impaired endogenous antioxidant status. In the present study, Japanese quail were fed on semi-purified diets containing
