The cause of serotonin toxicity or accumulation is an important factor in determining the course of treatment. Serotonin is catabolized by monoamine oxidase A in the presence of oxygen, so if care is taken to prevent an unsafe spike in body temperature or metabolic acidosis, oxygenation will assist in dispatching the excess serotonin. The same ...
A link between these types of drugs and cognitive impairment isn't a totally new discovery, but for the first time, researchers used brain imaging techniques to determine the physical changes ...
The narrowing of blood vessels leads to an increase in peripheral resistance, thereby elevating blood pressure. While vasoconstriction is a normal and essential regulatory mechanism for maintaining blood pressure and redistributing blood flow during various physiological processes, its dysregulation can contribute to pathological conditions.
Anticholinergic drugs are used to treat a variety of conditions: Dizziness (including vertigo and motion sickness-related symptoms); Extrapyramidal symptoms, a potential side-effect of antipsychotic medications
They have fast onset and offset kinetics, meaning that they have little or no effect at slower heart rates, and more effects at faster heart rates. Class Ib agents shorten the action potential duration and reduce refractoriness. These agents will decrease V max in partially depolarized cells with fast response action potentials. They either do ...
Is anger linked to heart attacks? New research finds that a bout of anger impairs blood vessel function which can raise the risk of atherosclerosis, which in turn raises heart disease risk.
Motor imagery for gait rehabilitation after stroke. The latest evidence supports the short-term benefits of motor imagery (MI) on walking speed in individuals who have had a stroke, in comparison to other therapies. [94] MI does not improve motor function after stroke and does not seem to cause significant adverse events. [94]
