The purpose of this study was to investigate the effects of a semisolid formulation of linseed oil, SSFLO (1%, 5%, or 10%) or in natura linseed oil on skin wounds of rats. We used wound models, incisional and excisional, to evaluate, respectively, the contraction/reepithelialization of the wound and resistance to mechanical traction. The groups (n = 6) treated with SSFLO (1% or 5%) began the pr...

In order to improve pyrolysis chromatographic analysis of materials that release polar functional groups e.g. carboxylic acids, a simple and rapid methylation method based on TDUpyrolysis/GC-MS in the presence of tetramethylammonium hydroxide (TMAH) was developed. Linseed oil was selected as test material because of its high triglyceride content comprising both saturated and unsaturated fatty a...

Seventy-two 8-week-old ram lambs from three breeds, Suffolk, Soay and Friesland, were offered one of four diets based on dried grass and formulated to have a similar fatty acid content (60 g/kg DM) and containing: Megalac (high in 16 : 0, control; Volac Ltd, Royston, Herts., UK), whole linseed (18 : 3n-3), fish oil (20 : 5n-3 and 22 : 6n-3) or whole linseed plus fish oil. The lambs were slaught...

The purpose of the present study was to explore the influence of microwave heating for different periods on the primary and secondary oxidation, total oxidation as well as conjugation of stripped and non-stripped linseed oils. Color index of the oil samples was also evaluated to show changes of color during periodical heating. It was generally found that a significant increase in peroxide value...

Sealers are used to enhance concrete durability through their ability to prevent moisture penetration and chloride intrusion, and, consequently, improve the freeze-thaw performance of the concrete and prevent corrosion of the steel reinforcement, respectively. This paper summarizes the results of three years of comprehensive field and laboratory investigations, undertaken at The University of M...

Feeding beef cattle a ration containing whole flax seeds (linseeds), flax (linseed) oil, rolled linseed or milled linseed increases the alpha-linolenic acid (ALA) and conjugated linoleic acid (CLA) content and decreases the omega-6/ omega-3 ratio, but has little effect on the saturated fat content of beef. Adding linseed to feedlot diets has been shown to increase the internal fat of heifers an...

Copper and nickel hydrogenations give a wide distribution of double bonds in the monoene fraction from both reduced soybean and linseed oils. With copper catalysts, high pressure hydrogenation reduces the extent of this double bond distribution when compared with low pressure hydrogenation. With nickel catalysts, some t.17-octadecenoate is formed but less than with a copper catalyst. In room od...

in this study, the effect of soluble chitosan, thyme oil and linseed oil on the mold resistance of wood and its surface properties was investigated. both low and medium molecular weight chitosan with concentration of 1 and 2% were used. cypress wood samples with dimensions of 20 × 20 × 70 mm and moisture content of 12% were saturated by the preservatives. the results showed that the maximum abs...

eggs l A preliminary study showed that maximum enrichment of egg lipid with omega-3 polyunsaturated fatty acids (LCPUFA) had not occurred after about 5 days on dietary oil regimens. When cod liver oil, canola oil or linseed oil was added at 7% to layer diets for 12 weeks, production parameters were usually better than on the commercial layer diet; e g g w e i g h t was normally higher on the oi...
