Human cells and mouse tissues metabolize n-3 docosapentaenoic acid (i.e., 7Z,10Z,13Z,16Z,19Z-docosapentaenoic acid, or clupanodonic acid) to a series of products that have been classified as specialized proresolvin mediators. Base on the analogy to docosahexaenoic acid metabolism to resolving D's, it is presumed that a 15-lipoxygenase, most ...
Human platelets pretreated with aspirin or atorvastatin metabolize the omega-3 DPA, clupanodonic acid (DPA n-3) by aspirin-treated or atorvastatin-treated COX-2 to a 13S-hydroperoxy intermediate (aspirin and atorvastatin change the activity of COX-2 from a cyclooxygenase to a hydroxyperoxidase-forming enzyme.
The production and activities of the SPM suggest a new view of inflammation wherein the initial response to foreign organisms, tissue injury, or other insults involves numerous soluble cell signaling molecules that not only recruit various cell types to promote inflammation but concurrently cause these cells to produce SPM which feed back on their parent and other cells to dampen their pro ...
Blood resistance varies depending on blood viscosity and its plugged flow (or sheath flow since they are complementary across the vessel section) size as well, and on the size of the vessels. Assuming steady, laminar flow in the vessel, the blood vessels behavior is similar to that of a pipe.
n-3 DPA is an n-3 fatty acid with the trivial name clupanodonic acid.It is an intermediate compound between eicosapentaenoic acid (EPA 5,8,11,14,17-20:5n-3 or timnodonic acid) and docosahexaenoic acid (DHA 4,7,10,13,16,19-22:6n-3 or cervonic acid) in the metabolic pathway of DHA in eucaryotes.
These DHA metabolites possess anti-inflammation and tissue-protection activities in animal models of inflammatory diseases; they are proposed to inhibit innate immune responses and thereby to protect from and to resolve a wide range of inflammatory responses in animals and humans. These metabolites are also proposed to contribute to the anti ...
Dr. McDonald adds that there is some evidence suggesting that apple cider vinegar can aid in weight loss and balance blood sugar levels, which helps control type 2 diabetes. Both diabetes and ...
Functional hyperaemia is an increase in blood flow to a tissue due to the presence of metabolites and a change in general conditions. When a tissue increases its activity, there is a well-characterized fall in the partial pressure of oxygen and pH, along with an increase in partial pressure of carbon dioxide, and a rise in temperature and the concentration of potassium ions.
