Abstract: The present invention is related to an improved process for obtaining oleochemical polyols from oils, principally of a vegetable origin. The polyols obtained consist of a mixture of ethers, esters, primary and secondary alcohols and have the characteristic of being self-compatible with the new blowing agents: hydrochlorofluorocarbons, HCFC's, hydrofluorocarbons, HFC's and hydrocarbons, HC's of a low molecular weight and low boiling point. The process of this invention is characterized because it uses Lewis type acids in such a way that they do not form precipitates and therefore it is not necessary to remove precipitates from the polyol. The process of the present invention makes it possible to obtain polyols with high functionality and controlled reactivity. These characteristics render the product suitable for use as a raw material in the production process of rigid foams, such as polyurethane for spraying, refrigeration and imitation wood, coatings, among others.

Abstract: Oleamide is an endogenous fatty acid primary amide that possesses sleep-inducing properties in animals and has been shown to effect seratonergic systems and block gap junction communication in a structurally specific manner. Certain agents can serve both as an oleamide agonist and as an inhibitor of fatty acid amide hydrolase. Fatty acid amide hydrolase is responsible for the rapid inactivation of oleamide in vivo. The structural features of oleamide required for inhibition of gap junction-mediated chemical and electrical transmission in rat glial cells are defined. Effective inhibitors fall into two classes of fatty acid primary amides of which oleamide and arachidonamide are the prototypical members. Of these two, oleamide constitutes the most effective and its structural requirements for inhibition of the gap junction are well defined.

Liposome populations were shown by dynamic light scattering and electron microscopy to range in size depending on the pore size of the filter, on the source of the lipids, and on the composition of the suspending buffer medium. In all cases the size ranges indicated highly homogeneous preparations.
