2. -adrenergic agonist. Beta2-adrenergic agonists, also known as adrenergic β2 receptor agonists, are a class of drugs that act on the β 2 adrenergic receptor. Like other β adrenergic agonists, they cause smooth muscle relaxation. β 2 adrenergic agonists' effects on smooth muscle cause dilation of bronchial passages, vasodilation in muscle ...
Beta blocker. Skeletal formula of propranolol, the first clinically successful beta blocker. Beta blockers, also spelled β-blockers, are a class of medications that are predominantly used to manage abnormal heart rhythms ( arrhythmia ), and to protect the heart from a second heart attack after a first heart attack ( secondary prevention ). [1]
Metoprolol is classified as a moderately lipophilic beta blocker. More lipophilic beta blockers tend to cross the blood–brain barrier more readily, with greater potential for effects in the central nervous system as well as associated neuropsychiatric side effects. Metoprolol binds mainly to human serum albumin with an unbound fraction of 0.88.
The beta-2 adrenergic receptor (β 2 adrenoreceptor), also known as ADRB2, is a cell membrane-spanning beta-adrenergic receptor that binds epinephrine (adrenaline), a hormone and neurotransmitter whose signaling, via adenylate cyclase stimulation through trimeric G s proteins, increases cAMP, and, via downstream L-type calcium channel interaction, mediates physiologic responses such as smooth ...
Coenzyme Q 10 (CoQ 10 / ˌ k oʊ k j uː ˈ t ɛ n /) also known as ubiquinone, is a naturally occurring biochemical cofactor (coenzyme) and an antioxidant produced by the human body. It can also be obtained from dietary sources, such as meat, fish, seed oils, vegetables, and dietary supplements.
View/Edit Mouse. β2 microglobulin ( B2M) is a component of MHC class I molecules. MHC class I molecules have α 1, α 2, and α 3 proteins which are present on all nucleated cells (excluding red blood cells ). [5] [6] In humans, the β 2 microglobulin protein [7] is encoded by the B2M gene. [6] [8]
Mayo Clinic is a nonprofit hospital system with campuses in Rochester, Minnesota; Scottsdale and Phoenix, Arizona; and Jacksonville, Florida. [22] [23] Mayo Clinic employs 76,000 people, including more than 7,300 physicians and clinical residents and over 66,000 allied health staff, as of 2022. [5] In addition, Mayo Clinic partially owns and ...
Acute respiratory distress syndrome (ARDS) is a type of respiratory failure characterized by rapid onset of widespread inflammation in the lungs. Symptoms include shortness of breath (dyspnea), rapid breathing (tachypnea), and bluish skin coloration (cyanosis).
