The effect of a doubly hydrophobically end-capped water soluble polymer (C18-PEO150-C18) on the properties of an oil-in-water (O/W) droplet microemulsion (R ∼ 2.85 nm) has been studied as a function of the amount of added telechelic polymer. Macroscopically one observes a substantial increase of viscosity once a concentration of ∼5 hydrophobic stickers per droplet is surpassed and effective cro...

Conjugated linoleic acid (CLA) is presently under extensive research because of its potent anticarcinogenic effects and also because of its effects on the immune system and on lipid metabolism. The biological effects of these acids are briefly reviewed. Ruminant edible products are the richest natural sources of CLA because they are supposed to be mainly derived from rumen biohydrogenation of l...

The study of soil microbial populations and diversity is an important way to understanding the soil energy process. In this study we analyzed the characteristics of soil microbial populations of the Tarim Desert Highway shelter-forest, by identifying microbial fatty acids and using methods of conventional cultivation. The results illustrated that the amount of soil microbial activity and the di...

The molecular-species compositions of the diacyl classes of the major phospholipids from the brain and retina of rainbow trout (Salmo gairdneri) were determined. A total of 46 possible species was identified. Didocosahexaenoyl species were major components of phosphatidylcholine (PC), phosphatidylethanolamine (PE) and phosphatidylserine (PS) from retina, comprising 14.1, 41.3 and 28.3% of the r...

Background. Acne is a dermatosis that involves an altered sebum pattern. Objectives. (1) To evaluate if a treatment based on antibiotics (lymecycline) can alter fatty acids contents of the sebum of patients with acne; (2) to evaluate if oral supplementation of fatty acids can interfere with fatty acids contents of the sebum of patients with acne; (3) to evaluate if there is any interaction in f...

Walnut (Juglans regia L.) is the oldest fruit grown in world and grows spontaneously almost throughout Romania. In this study, physical properties chemical composition of twenty types walnuts from three different locations Romania were studied. The analyzes that performed were: walnut dimensions shape (nut diameter, nut length, size), (walnut weight, kernel weight percentage kernel) external ex...

The composition of triacylglycerols (TAGs) is a very useful parameter to understand several properties of creams and anhydrous milk fat products such as nutritional value, technological applications, and textural properties. In this paper, the molecular species of TAGs of equine milk were identified using a combination of nonaqueous reversed phase high-performance liquid chromatography, electro...

A systematically varying series of monolayer-protected clusters (MPCs) was prepared by exposing small gold nanoparticles ( approximately 2 nm in diameter) to the following four adsorbates: n-octadecanethiol ( n - C18), 2-hexadecylpropane-1,3-dithiol ( C18C2), 2-hexadecyl-2-methylpropane-1,3-dithiol ( C18C3), and 1,1,1-tris(mercaptomethyl)heptadecane ( t - C18). The resultant MPCs were character...
