The biology of depression is the attempt to identify a biochemical origin of depression, as opposed to theories that emphasize psychological or situational causes. Scientific studies have found that different brain areas show altered activity in humans with major depressive disorder (MDD) . [ 1 ]
X would instead be a sufficient cause of y when the occurrence of x implies that y must then occur. [2] in other words, when some factor is sufficient to cause an effect, the presence of the cause guarantees the occurrence of the effect. [3] However, a different cause z may also cause y, meaning that y may occur without x occurring.
The serotonin transporter (SERT or 5-HTT) also known as the sodium-dependent serotonin transporter and solute carrier family 6 member 4 is a protein that in humans is encoded by the SLC6A4 gene. [5] SERT is a type of monoamine transporter protein that transports the neurotransmitter serotonin from the synaptic cleft back to the presynaptic ...
In the late 1960s and early 1970s, Dexamyl spansules—a clear and green capsule containing green and white "beads"—became popular as a street-drug upper nicknamed "Christmas trees", a reference to its appearance. [6] In his autobiography My Life of Absurdity, author Chester Himes writes of his use of Dexamyl in the mid-1950s. He also writes ...
In the simplest example of the method, an equal volume of beads are added to a cell or tissue suspension in a test tube and the sample is vigorously mixed on a common laboratory vortex mixer. While processing times are slow, taking 3–10 times longer than that in specialty shaking machines , it works well for easily disrupted cells and is ...
This is seen in that immune activity does not appear to be enough on its own to cause depression. [39] Evidence for this comes primarily from treatments that involve the pro-inflammatory IFN-α, which is commonly used in treating viral infections but only results in major depression in about one third of patients.
In the biological sciences, a multiplex assay is a type of immunoassay that uses magnetic beads to simultaneously measure multiple analytes in a single experiment. [1] A multiplex assay is a derivative of an ELISA using beads for binding the capture antibody. Multiplex assays are still more common in research than in clinical settings.
Risk factors for mental illness include psychological trauma, adverse childhood experiences, genetic predisposition, and personality traits. [7] [8] Correlations between mental disorders and substance use are also found to have a two way relationship, in that substance use can lead to the development of mental disorders and having mental disorders can lead to substance use/abuse.
