Use of fatty alcohol ethoxylates as Penetration promoters The present invention relates -to the novel use. It is generally known that many agrochemically active compounds, -in particular those having systemic action, have to penetrate into the plant to be able to unfold their activity evenly throughout the plant. Thus, when the active compound is taken.

Miller and Grant M. The blood brain barrier BBB is a selectively permeable cellular boundary between the brain and the peripheral circulation. The principal component of the BBB is the capillary or microvessel endothelial cell Figure 1.
Background and aims: The study aims to analyze of fatty acid FA composition of arteries and blood plasma in atherosclerosis. Material and method: The blood plasma in patients with coronary atherosclerosis was studied, the blood from healthy volunteers was used as control. There were also analyzed arteries of patients with severe atherosclerotic lesions and arteries of people with significantly less atherosclerotic changes.
Linoleic, oleic, palmitoleic, palmitic, and stearic fatty acids FAs are commonly used in dermatological formulations. They differ by their structure, presence in the skin, and mode of application in pharmaceuticals and cosmetics compounding. These FAs are also known as chemical penetration enhancers, but their mechanisms of penetration enhancement and effect on barrier characteristics of the skin require additional study.
While aspects of cellular fatty acid uptake have been studied as early as 50 years ago, recent developments in this rapidly evolving field have yielded new functional insights on the individual mechanistic steps in this process. The extremely low aqueous solubility of long chain fatty acids LCFA together with the very high affinity of serum albumin and cytoplasmic fatty acid binding proteins for LCFA have challenged the limits of technology in resolving the individual steps of this process. To date no single mechanism alone accounts for regulation of cellular LCFA uptake. The emerging picture is that the cell has multiple, overlapping mechanisms that assure adequate uptake and directed intracellular movement of LCFA required for maintenance of physiological functions.
