1.4 Physiology of the Endocannabinoid System 1.4.1 Mechanisms Underlying the Retrograde Control of Synaptic Signaling Endocannabinoids, particularly 2-AG, act as retrograde messengers in the CNS. This negative feedback mechanism is conserved at glutamatergic synapses in the spinal cord, midbrain, striatum...
In summary, the AhAREB1/AhNAC2 protein complex functions as a negative feedback regulator of drought-induced ABA biosynthesis in peanut. Plants encounter various environmental stresses throughout life, of which drought is one of the most serious adverse factors restricting plant survival, growth and...
this seemingly paradoxical function of DDX5 provides the ideal situation when targeting DDX5 for cancer therapeutics as it provides the ability to potentially avoid adverse side effects on physiology and normal tissues while
(having a general expectation that life will be positive) has been shown to influence our physiology.Segerstrom, Taylor, Kemeny, and Fahey (1998), for example, found that optimists had enhanced immune function compared to thosewho were more pessimistic.Segerstrom et al. (1998)speculated that ...
(e.g., distancing), as it does not only dampen negative emotion. It also enhances positive emotion, leading to a greater overall emotion change, which is reflected in subjective reports, physiology39, and differential neural responses linked to reward (striatum, VMPFC)20, beyond cognitive ...

What is a negatively charged particle? The negative charge definition is any particle that experiences a force from the negative to the positive in an electric field. Some examples of negatively charged particles are Electrons Antiprotons Muons Tauons Anions (or negatively charged ions)Are...

A recent study on the physiology of cancer cells showed an increase of dNTP pools was accompanied by higher mutation rates due to reduced fidelity of DNA replication34. In contrast, early studies showed that a decrease in dNTP pools by hydroxyurea (HU) lead to an S-phase arrest by ...
