Aldehydes are electrophilic compounds to which humans are pervasively exposed. Despite a significant health risk due to exposure, the mechanisms of aldehyde toxicity are poorly understood. This ambiguity is likely due to the structural diversity of aldehyde derivatives and corresponding differences in chemical reactions and biological targets. To gain mechanistic insight, we have used parameter...

Steers were fed 70∶30 forage∶concentrate diets for 205 days, with either grass hay (GH) or red clover silage (RC), and either sunflower-seed (SS) or flaxseed (FS), providing 5.4% oil in the diets. Compared to diets containing SS, FS diets had elevated (P<0.05) subcutaneous trans (t)-18:1 isomers, conjugated linoleic acids and n-6 polyunsaturated fatty acid (PUFA). Forage and oilseed type influe...

milk and dairy products are in diet almost every day. milk fat contains 70% of saturated fatty acids which can cause an increase in total and low-density lipoprotein cholesterol, and the risk of cardiovascular diseases. therefor, modification of fat composition at dairy products such as yoghurt seems necessary. walnut has high amount of essential fatty acids, anti oxidants and other beneficial ...

Condensation of aromatic aldehydes with benzoyl acetone under specified conditions yieldedtwo series of polycarbonyl compounds in which the keto group is attached to olefinic linkage.Spectral and analytical data revealed the formation of an unsaturated triketone from pyridine-3-carbaldehyde and unsaturated diketone from furfural, salicylaldehyde and 2-hydroxynaphthaldehyde. Analytical, IR, 1H N...

Prolonged niacin treatment elicits beneficial effects on the plasma lipid and lipoprotein profile that is associated with a protective CVD risk profile. Acute niacin treatment inhibits nonesterified fatty acid release from adipocytes and stimulates prostaglandin release from skin Langerhans cells, but the acute effects diminish upon prolonged treatment, while the beneficial effects remain. To g...

Our hypothesis was that different sources of unsaturated fatty acids from oilseeds (sunflower, soybeans, and cottonseed) could alter milk yield, acid profile, the amount yielded in milk. It aimed to evaluate effects lipid on yield composition primiparous Girolando cows. Five cows lactation (35 ± 8 days), with 410 7.15 kg BW were randomly distributed a 5 x Latin square. experimental diets, namel...

In Mexico, corn is the most widely used cereal, however, in arid areas it not possible to cultivate it, so white sorghum represents an alternative. However, important know varieties nutritional content. Therefore, this study proximal profile and fatty acids of six grown Mexico were evaluated. Proximate analysis was carried out based on AACC methods gas chromatography had been for acid analysis....

Balsam fir needle retention and fatty acid profile changes due to cold acclimation throughout autumn, but little is known about the relationship between these two phenomena. The objective was examine differences in FAs contrasting abscission resistant balsam genotypes autumn early winter. Branches from with low high resistance (NAR) were collected September January analyzed for FA composition. ...
