Receptor antagonist

The initial start point of ERK is when a signalling molecule binds to the receptor on the cell surface; this causes a change in the cell. ERK proteins communicate by actually adding phosphate groups to nearby proteins. If these proteins become mutated in anyway it can cause cancer. This pathway can become truly damaging to the…

synaptogenesis. During axon guidance, growth cones navigate the microenvironment and encounter interaction with receptor proteins and cell surface bound ligands in route to their target field. Their ultimate goal upon arrival is to create functional synaptic connections. Synapse formation involves organized cell morphological and structural modifications that are carried out through ligand-receptor interactions, intracellular signaling cascades, and complex filamentous actin remodeling.…

Mouth ulcers can also occur due to methotrexate being a folic acid antagonist but it is less likely to occur if folic acid supplements are taken. Folic acid supplements can also usually control gastrointestinal side effects i.e. include gingivitis, nausea, pharyngitis, stomatitis, anorexia, hematemesis, melena, GI ulcer’s…

glucose levels. When blood sugar levels rises, like after a meal, insulin is secreted by the beta cells in the islets of Langerhans in primary response to decrease the blood concentration of glucose. As seen in diagram 2. The beta cells act as the receptor and the control. The beta cells detect a rise in glucose and in response secretes insulin. The islets of Langerhans do not depend on the nervous system for their output of insulin. As a result the beta cells respond directly to blood glucose…

SKELETAL MUSCLE PROTIENS Acting:- • Contractile protein. • Consists of 2 alpha helical strands of g-acting molecules bond in succession. • Each g-acting has a required site where the s1 piece of the myosin cross-bridge multifaceted binds right through weight reduction. Myosin:- • Contractile protein. • Consists of two profound (shape tail constituency and two cross-bridges that disconnect with acting to produce force) and four light chains (that influence cross-bridge cycling kinetics and…

about CFC’s contributing to ozone depletion (Swisher, n.d.). Albuterol works by acting as an agonist of β2 adrenergic receptors responsible for bronchodilation, uterine relaxation, and vasodilation of the arterioles in the lungs, heart, and skeletal muscle (Usher, n.d.c). Albuterol, used primarily as a rescue inhaler, utilizes the bronchodilation component of β2 adrenergic receptor stimulation in order to treat bronchospasms caused by asthma. Once inhaled, albuterol takes 5 to 15 minutes to take…

Co-activation is seen in this experiment where the bicep, the flexor, resembles the agonist and the triceps, the extensors, resemble the antagonist. When the bicep muscle is active by being in its flexed position; its motor neurons are excited whereas the motor neurons in opposition of the triceps are somewhat inhibited. However, these triceps muscles still contribute to minor activities compared…

Coronary risk factors and risk of diabetic cardiovascular complications: Diabetes usually occurs among elderly as part of metabolic syndrome, which includes abdominal obesity, hypertension, hyperlipidemia, and all these factors can act to promote diabetic complications so aggressive treatment of diabetes and associated coronary risk factors is recommended to prevent diabetic complications (Fowler 2008) (Boyle 2007). The main cause of death in diabetic patients is cardiovascular complications…

secrete HCL and essential factors. Parietal cells are located in the gastric glands in the lining of the fundus and in the body of the stomach. The capacity of the stomach to secrete HCL is related to amount of parietal cell. Parietal cells accept receptors for three stimulators of acid secretion which are Acetylcholine, Gastrin,…

Introduction Sudden cardiac death (SCD) is a world wide health problem resulting in one-fifth of unexpected deaths in the western world. Ventricular fibrillation (VF) is one of the life-threatening arrhythmias contributing to the increasing number of individuals needing urgent medical assistance (Wellens, Gorgels & Munter, 2013). The following case study will explore a complex critically ill patient who has suffered from a ventricular tachycardia (VT) and VF due to dilated left ventricle (LV)…
