objective: although key roles for dietary vitamin e (vite) and fatty acid (fa) in fertility have been confirmed, limited data are available on the effects of vite alone, or a constant level of vite supplemented by dietary omega-6 and omega-3 fas in combination on male reproduction. consequently in this paper, the effects of vite, sunflower oil, fish oil and their combination on rat sperm were i...

Abstract Catalytic ester-interchange reactions, analogous to mutation and recombination, allow new sequence information be written statistically into poly(ester-imide) chains based on NDI (1,4,5,8-naphthalenetetracarboxylic diimide) units. Thus, both the insertion of cyclic ester cyclopentadecanolide (“exaltolide”) an NDI-based homopolymer quantitative exchange between two different homopoly(es...

this study investigates the effects of replacement of fish oil by sunflower oil and colsa oil as the vegetable oils, on growth and nutrition performance and survival rate of  rutilus frissi kutum with initial average weight 3.65±0.39 g over 8 weeks. three diets were supplemented with 8.5% of either fish oil (control), sunflower oil, and colsa oil, respectively in triplicates. after the experime...

This highlight review describes the recent development of an electrophile-triggered 1,2-metallate rearrangement organoboronic ester ate-complex, which proceeds through 1,2-difunctionalization carbon–carbon σ- and π-bonds, using strain energy as a driving force. Coupling reactions small ring carbocyclic boronic esters, such cyclopropyl-, bicyclo[1.1.0]butyl-, cyclopropenyl-boronic ester, are sum...

The present study was designed to determine the effects of supplemental fat or oil rich in oleic acid on the fatty acid profiles (FAP) and physical and sensory traits of pork carcasses. Sixty barrows and gilts were equally distributed among five dietary treatments consisting of a control diet of corn and soybean meal and four similar test diets that contained 10% animal fat (45.3 oleic), safflo...

BACKGROUND AND AIMS Concomitant intake of statins together with certain foods may affect their therapeutic effects. The purpose of this preliminary study was to determine the modulating effect of two culinary oils on the hypolipemic effect of statins. SUBJECT AND METHODS Twenty-five men with severe hypercholesterolemia and high estimate cardiovascular risk (> 20% according to the Adult Treatm...

This paper presents a series of structural modifications of epoxidized ricinoleic acid for biolubricant to improve the cold flow behavior and oxidation stability of vegetable oils through measurement of pour point (PP) and oxidation onset temperature (OT) and signal maximum temperature (SMT) of each synthetic compound. The results showed that butyl 10,12-dihydroxy-9-behenoxystearate with bulky ...

The antioxidant activity of tocopherols in vegetable oils was shown to chiefly depend on the amount and the tocopherol homolog present. However, the most effective ratio of tocopherol homologs with regard to the antioxidant capacity has not been elucidated so far. The present study analyzed the effect of different tocopherol concentrations, homologs and ratios of homologs on markers of lipid ox...

The current study describes the emphatic use of response surface methodology for the optimized biodiesel production using chemical and enzymatic transesterification of rice bran and sunflower oils. Optimal biodiesel yields were determined to be 65.3 ± 2.0%, 73.4 ± 3.5%, 96.5 ± 1.6%, 89.3 ± 2.0% and 41.7 ± 3.9% for rice bran oil and 65.6 ± 1.2%, 82.1 ± 1.7%, 92.5 ± 2.8%, 72.6 ± 1.6% and 50.4 ± 2...

The failure of a tailing pond dam at the Aznalcóllar pyrite mine (SW Spain) in April 1998 released a toxic spill affecting approximately 4300 ha along the Agrio and Guadiamar valleys. Two years later, we have studied yield and concentration of mineral nutrients and trace elements in sunflower plants grown in the spill-affected soil, and in an adjacent unaffected soil as comparison. The study ha...
