Exempel på hur man kan använda CONTRACTILITY i en mening

• Microfilament functions include cytokinesis, amoeboid movement, cell motility, changes in cell shape, endocytosis and exocytosis, cell contractility, and mechanical stability.
• Short-term treatment of cardiac decompensation can be achieved through administration of dobutamine, resulting in an increase in heart contractility via an inotropic effect.
• The three curves illustrate that shifts along the same line indicate a change in preload, while shifts from one line to another indicate a change in afterload or contractility.
• This modulating role is separate from the homeometric and heterometric regulatory mechanisms that control myocardial contractility.
• Negative inotropic agents decrease myocardial contractility and are used to decrease cardiac workload in conditions such as angina.
• Tamoxifen has been identified and used to effectively improve blood flow, reduce uterine contractility and pain in dysmenorrhea patients.
• VIP stimulates contractility in the heart, causes vasodilation, increases glycogenolysis, lowers arterial blood pressure and relaxes the smooth muscle of trachea, stomach and gallbladder.
• It is indicated when parenteral therapy is necessary for inotropic support in the short-term treatment of patients with cardiac decompensation due to depressed contractility, which could be the result of either organic heart disease or cardiac surgical procedures.
• Increasing contractility is done primarily through increasing the influx of calcium or maintaining higher calcium levels in the cytosol of cardiac myocytes during an action potential.
• Enhanced contractility of coronary vascular smooth muscle due to reduced nitric oxide bioavailability caused by a defect in the endothelial nitric oxide synthetase enzyme which leads to endothelial function abnormalities.
• Rhythmicity and contractility of the heart may be normal, but the stiff walls of the heart chambers (atria and ventricles) keep them from adequately filling, reducing preload and end-diastolic volume.
• The cardiopulmonary baroreflex responds to an increase in CVP by decreasing systemic vascular resistance while increasing heart rate and ventricular contractility in dogs.
• Other clinical signs include abdominal pain, breathing and swallowing difficulty, convulsions, ptosis, hemolysis, and hypotension from depression of myocardial contractility.
• Phellodendron amurense is able to inhibit prostatic contractility suggesting that it may be useful in the treatment of urological disorders caused by prostatic urethral obstruction such as benign prostatic hyperplasia (BPH).
• Levosimendan is a calcium sensitizer — it increases the sensitivity of the heart to calcium, thus increasing cardiac contractility without a rise in intracellular calcium.
• Perineurial cells are sometimes referred to as myoepithelioid due to their epithelioid and myofibroblastoid properties including tight junctions, gap junctions, external laminae and contractility.
• Hyperdynamic precordium can also be due to hyperthyroidism, and thus indicates an increased cardiac contractility, with systolic hypertension.
• Stricker is remembered for his extensive studies in the fields of histology and experimental pathology, and is credited with making discoveries involving the diapedesis of erythrocytes and the contractility of vascular walls.
• Homeometric autoregulation, in the context of the circulatory system, is the heart's ability to increase contractility and restore stroke volume when afterload increases.
• On a microscopic scale via observation and dissection, the contractility of muscle was to be explained by pneumatic expansion, a popular explanation supported by Descartes and Borelli, or inherent shape deformation, postulated by Nicolas Steno and Albrecht von Haller to an extent, based upon principles of fluids and statics.
