A cardiac stress test is a cardiological examination that evaluates the cardiovascular system's response to external stress within a controlled clinical setting. This stress response can be induced through physical exercise (usually a treadmill) or intravenous pharmacological stimulation of heart rate.
The name multiple chemical sensitivity has been criticized, partly because MCS is not a sensitivity in the allergic or immunological meaning of that word. [5] Being more sensitive than average to some chemical exposures (e.g., secondhand smoke) is fairly common. [5] MCS is generally used to refer to more significant disability. [5]
The nitroprusside reaction is a chemical test used to detect the presence of thiol groups of cysteine in proteins. Proteins with the free thiol group give a red colour when added to a solution of sodium nitroprusside in aqueous ammonia. Some proteins test positive when denatured, indicating that thiol groups are liberated. [62] [63] [64]
Adrenochrome is a chemical compound produced by the oxidation of adrenaline (epinephrine). It was the subject of limited research from the 1950s through to the 1970s as a potential cause of schizophrenia. While it has no current medical application, the semicarbazide derivative, carbazochrome, is a hemostatic medication.
The ACTH test (also called the cosyntropin, tetracosactide, or Synacthen test) is a medical test usually requested and interpreted by endocrinologists to assess the functioning of the adrenal glands' stress response by measuring the adrenal response to adrenocorticotropic hormone (ACTH; corticotropin) or another corticotropic agent such as tetracosactide (cosyntropin, tetracosactrin; Synacthen ...
Cellular stress response is the wide range of molecular changes that cells undergo in response to environmental stressors, including extremes of temperature, exposure to toxins, and mechanical damage. Cellular stress responses can also be caused by some viral infections. [1]
The adverse effects of mechlorethamine depend on the formulation. [15] When used in chemical warfare, it can cause immunosuppression and damage to mucous membranes of the eyes, skin, and respiratory tract. Mucous membranes and damp or damaged skin are more affected by exposure to HN-2.
Adverse effects, like therapeutic effects of drugs, are a function of dosage or drug levels at the target organs, so they may be avoided or decreased by means of careful and precise pharmacokinetics, the change of drug levels in the organism in function of time after administration. Adverse effects may also be caused by drug interaction. This ...
