The technique of gas-liquid chromatography-chemical ionization mass spectrometry can easily identify trace peaks and unresolved peaks on gas-liquid chromatography, utilizing MH(+) ions of chemical ionization mass spectra. In polyunsaturated fatty acid methyl esters such as C22:5 and C22:6, the determination of molecular weights that are difficult to determine by electron impact mass spectrometr...

High plasminogen activator inhibitor (PAI)-1 levels and poor dietary fat quality are potential risk factors for cardiovascular disease. The aim was to investigate the cross-sectional associations between PAI-1 activity and dietary nutrient intake, focusing on fat quality, in a population-based study of 871 men aged 70 years. The relationship between PAI-1 and the fatty acid composition in serum...

OBJECTIVE To assess the effect of food containing high concentrations of fish oil omega-3 fatty acids and a low omega-6-omega-3 fatty acid ratio on clinical signs of osteoarthritis in dogs. DESIGN Randomized, double-blinded, controlled clinical trial. ANIMALS 127 client-owned dogs with osteoarthritis in 1 or more joints from 18 privately owned veterinary clinics. PROCEDURES Dogs were rand...

The fatty acid composition of serum cholesteryl esters is used as a qualitative biomarker of fatty acid intake, but quantitative data are scarce. Between 1987 and 1992, the authors fed various fatty acids in four controlled trials to 232 healthy Dutch volunteers and measured the proportion of fatty acids in participants' cholesteryl esters. Each 10% of energy fed as linoleic acid (18:2) raised ...

background and objectives: probiotic bacteria are able to absorb fatty acids present in the culture medium and convert them into intracellular fatty acids, which may affect the physicochemical properties of probiotics. subsequently, changing the composition of cellular fatty acids of probiotics improves the electron acceptance capacity of these microorganisms, and results in an increased adhesi...

since long term dietary fatty acide intake is reflected in the fatty acide composition of  Adipose tissue, this study was aimed to compare the adippose tissue fatty acide profile of angiography documented CAD (test)and non-CAD(control)  patients.the first group were 25 patients who underwent coronary artery bypass graft surgery in open heart surgery section of Shahid Beheshti hospital of Kerman...

Serum lipoprotein[a] (Lp[a]) is a strong risk factor for coronary heart disease. We therefore examined the effect of dietary fatty acid composition on serum Lp[a] levels in three strictly controlled experiments with healthy normocholesterolemic men and women. In Expt. I, 58 subjects consumed a control diet high in saturated fatty acids for 17 days. For the next 36 days, 6.5% of total energy int...

dietary factors are suggested to be involved in recent increases in the prevalence of asthma. the differences in dietary intake of 23 asthmatic and 317 non-asthmatic students were investigated, who were chosen by multistage stratified cluster sampling. the dietary data were assessed by food frequency questionnaire and a 24-h recall form. total calorie and fat intake were similar. daily intake o...

different layers of acorn (quercus infectoria), hull, seed coat and seed kernel were analyzed for determination of chemical composition. the results of the preliminary analysis showed that acorn contained more than 65% carbohydrates, 8% lipid and 10% tannin among other constituents. the fatty acid composition of the seed oil was determined using thin layer chromatography and comparing with ...
