abstract this experiment was conducted to study the effect of south-west climatic conditions on quantitative and qualitative of fatty acids in dog rose (rosa canina l.) seeds collected from five regions including: semirom (isfahan province), kiar and gerdbishe (charmahal and bakhtiari province), yasuj and meymand (kohgiluye and boyer ahmad province). oil was extracted using soxhlet apparatus; t...

An experiment was undertaken to evaluate the effects of three-day periods of high and very high temperatures (32/24C and 37/25C day/night temperatures, respectively) at different stages of seed development (10, 20 and 30 days after flowering) on the fatty acid composition of a high erucic acid rapeseed (HEAR) and a mid oleic acid canola (MOAC) breeding line (“cultivar”). The earliest formed see...

UNLABELLED In a randomized, double-blinded, controlled clinical trial, participants with peripheral arterial disease (75% hypertensive) consumed 30 g of milled flaxseed/d for 6 months. The flaxseed group exhibited significant reductions in systolic (-10 mm Hg) and diastolic (-7 mm Hg) blood pressure. Flaxseed contains the n3 fatty acid α-linolenic acid. Plasma α-linolenic acid increased with in...

We studied the effects of five high-fat semi-purified diets varying at a 4% (w/w) level in either stearic, oleic, linoleic, alpha-linolenic, or gamma-linolenic acid on body fat and energy metabolism in BALB/c mice. A diet containing caprylic, capric, lauric, and myristic acid was used as a reference diet and a diet with 4% conjugated linoleic acid (CLA) was used as a positive control as it is k...

Three experiments were conducted by in vitro incubations in ruminal fluid to investigate the effects of pH and amounts of linoleic and linolenic acids on the extent of their biohydrogenation, the proportions of conjugated linoleic acid (CLA) and trans-C18:1 as intermediates, and the ratio trans-10:trans-11 intermediates. The effects of pH and amount of linoleic acid were investigated in kinetic...

The relationships between n-3 and n-6 fatty acids in subcutaneous fat, BMI and overweight status were investigated in eighty-eight children from Crete and Cyprus. Overweight status, BMI and serum lipid levels were similar in children at both locations, but Cretan children had higher levels of total MUFA than Cypriot children (62.2 (sd 2.8) v. 52.2 (sd 2.8) % area, respectively, P<0.001) and con...

The artificial gene D6D encoding the enzyme ∆⁶desaturase was designed and synthesized using the sequence of the same gene from the fungus Thamnidium elegans. The original start codon was replaced by the signal sequence derived from the wheat gene for high-molecular-weight glutenin subunit and the codon usage was completely changed for optimal expression in wheat. Synthesized artificial D6D gene...

OBJECTIVE To study the efficacy and tolerability of borage oil, which contains a high concentration of gamma linolenic acid, in children and adults with atopic eczema. DESIGN Single centre, randomised, double blind, placebo controlled, parallel group trial. SETTING Acute district general hospital in Nuneaton, England. PARTICIPANTS 151 patients, of whom 11 failed to return for assessment, ...

Omega-3 fatty acids have potential antiatherogenic, antithrombotic, and antiarrhythmic properties, but their role in coronary heart disease remains controversial. To evaluate the association of omega-3 fatty acids in adipose tissue with the risk of myocardial infarction in men, a case-control study was conducted in eight European countries and Israel. Cases (n=639) included patients with a firs...

The fatty acid composition of wheat seedling roots changed in response to temperature. As temperature declined, the level of linolenic acid increased and the level of linoleic acid decreased. The distribution of phospholipid classes was not influenced by temperature. Phosphatidyl choline and phosphatidyl ethanolamine were the predominant phospholipids isolated and comprised 85% of the total lip...
