Endogenous Depression is an atypical sub class of the Mood Disorder , Clinical Depression A.K.A. Major Depressive Disorder . Endogenous Depression includes patients with treatment refractory, unipolar, non psychotic, Major Depressive Disorder, characterized by a dysregulation of the Endogenous Opioid System and not of the Monoaminergic System. Patients who fall in this sub class typically respond very well to synthetic opioids which act on the opioid receptors and thought to result in increased serotonin production and norepinephrine reuptake inhibition, including Tramadol, Tapentadol, Buprenorphine, and other similar, synthetic, atypical, opioid analgesics. However, due to the addictive qualities and taboo nature opioids have in the eyes of the general public, doctors have been reluctant to delve into research on or treatments for Endogenous Depression, and therefore, patients who suffer the condition usually go untreated. ref cite journal coauthors Nyhuis P W, Specka M, Gastpar M title Does the antidepressive response to opiate treatment describe a subtype of depression? journal European Neuropsychopharmacology year 2006 volume 16 series 4 accessdate 10 March 2011 ref ref cite journal ... 7714228 accessdate 10 March 2011 ref It is also thought that Endogenous Depression is a mood disorder ... mood may not be triggered by any external element.

In pharmacology , an endogenous agonist for a particular Receptor biochemistry receptor is a compound naturally produced by the body which binds to and agonist activates that receptor. For example, the endogenous agonist for 5 HT receptor serotonin receptors is serotonin , and the endogenous agonist for dopamine receptor s is dopamine . ref Goodman and Gilman s Manual of Pharmacology and Therapeutics. 11th edition, 2008 . p14. ISBN 0071443436 ref In general, receptors for small molecule neurotransmitter s such as serotonin will have only one endogenous agonist, but often have many different receptor subtypes e.g. 13 different serotonin receptor receptors for serotonin . On the other hand, neuropeptide receptors tend to have fewer subtypes, but may have several different endogenous agonists. This allows for a high degree of complexity in the bodies signalling system, with different tissues often showing quite distinct responses to a particular ligand . Some endogenous Antagonist pharmacology antagonists and inverse agonist s are also known e.g., kynurenic acid at the NMDA receptor , but these are much less common.

Economics sidebar multiple section y expert November 2011 refimprove November 2011 Endogenous money creation or destruction can be thought of as the concept that each participant in the economy has their own version of a printing press for money. This concept was explained by Irving Fisher in his treatise on The Theory of Interest 1930 in terms of the value of currency being affected by two potentially opposing movements expected growth in the money supply reducing the real purchasing power of money and expected increases in productivity increasing the real purchasing power of money. This means that participants can impact on the value of currency in a number of ways 1 Investment choices to invest in non productive money equivalents rather than to invest directly in productive assets effectively increases the money supply, reducing the real value of currency. 2 Demands for higher wages or supplier payments can increase the financing requirements of firms, creating a risk of supplier led inflation , effectively reducing the real value of currency. 3 Choices made about the level of contribution to productivity can increase the real value of currency, in fact this is the only mechanism ...
