Beta blockers (β-blockers or BBs) were invented and designed by Sir James Black‚ who was a Nobel Prize winning scientist. Black designed beta blockers to counteract stimulated adrenergic effects. He demonstrated that‚ by blocking the cardiac beta-receptors‚ these agents could cause inhibitory effects on the sinus node (chronotropic effect)‚ atrioventricular node (dromotropic effect)‚ and on myocardial contractility (inotropic effect).1 It is important to note that not all beta receptors (β-receptors)

Beta Blockers In Case of Heart Failure Noor M. Al-Tarouti Beta Blockers in Case of Heart Failure Introduction : Beta-blockers‚ also known as beta antagonists‚ beta-adrenergic blocking agents‚ or beta-adrenergic antagonists‚ are drugs that are prescribed to treat several different types of conditions‚ including hypertension (high blood pressure)‚ angina‚ some abnormal heart rhythms‚ heart attack (myocardial infarction)‚ anxiety‚ migraine‚ glaucoma‚ and overactive thyroid symptoms.

of memory persistence‚ that is‚ knowing which mechanisms in the learning process are affected and how. The purpose of this experiment is to analyze how stress by immobilization affects the persistence of long-term memory along with administration of beta-adrenergic antagonist treatment‚ theoretically resulting in different memory retention over 7 days. For the testing purposes‚ the author gathered 170 male Wistar rats ranging from two to three months of age and weighting 250-280 grams. These testing

Hypertensive heart disease is obviously caused by high blood pressure. High blood pressure means the pressure inside the blood vessels‚ which is arteries is too high. As the heart pumps‚ it must pump against the pressure‚ so it must work harder. Gradually‚ the heart muscles will be thicken. Sometimes it does not get enough oxygen because the muscle is too thick. It influenced your heart to pump regularly and its functions. These changes could effect the thickening and enlargement of the heart (left
