The main objective of phase 3 trials is to verify the therapeutic action of a new substance in a large number of patients, essentially to determine the risk/benefit ratio. Before phase 3, the substance is not regarded as a drug, but after a positive phase 3 trial it becomes a drug.
Answer: 70 to 120 seconds is the usual amount of time for blood to clot without heparin. 180 to 240 seconds is the usual amount of time for blood to clot with heparin.
Explanation:
Water-hammer pulse is what the nurse would find when assessing patient with chronic aortic regurgitation in the emergency unit of a health care facility.
A strong, quick beat which collapses immediately is a water hammer pulse. Heart sounds may include a soft or absent S1, S3, or S4 and a soft, high-pitched diastolic murmur.
Chronic aortic regurgitation is a condition in which heart's aortic valve does not close tightly. It is caused by two common causes i.e., rheumatic heart disease and bacterial endocarditis. To treat this condition, a surgery is needed to replace the diseased aortic valve with a mechanical valve.
There are four stages for aortic regurgitation: at risk, asymptomatic with progressive aortic regurgitation, asymptomatic with severe aortic regurgitation, symptomatic with aortic regurgitation.

The<u> neurohypophysis </u>releases hormones directly into the blood and the <u>adenohypophysis</u> receives hormones from the hypothalamus cells which in turn causes the release of more hormones.
What are neurohypophysis and adenohypophysis?
The hormones produced by the posterior pituitary are released into the bloodstream directly from the axonal terminals of their source neurons, this region of the pituitary is frequently referred to as neurohypophysis. Two peptide hormones, vasopressin, and oxytocin act as the structural base of a neuro-humoral system that coordinates fluid balance and reproductive function.
The anterior pituitary (or adenohypophysis), controls a number of physiological processes (including stress, growth, reproduction, and lactation). Melanocyte stimulating hormone is produced and secreted by the intermediate lobe.
