An acute response is an immediate response to exercise. Acute exercise will last throughout the full length of your training session. During the training session our bodies begin to respond to the exercises we are doing and begin to feel the changes within our bodies and mind due to physical strain and stress of the physical activity in lots

Levetiracetam Levetiracetam is probably a major breakthrough in the treatment of epilepsies. It is a highly effective‚ broad-spectrum‚ one of second generation AED with a unique mechanism of action. Chemical structure: Levetiracetam is a single enantiomer‚ (S)-α-ethyl-2-oxo-pyrrolidine acetamide. Its molecular formula is C8H14N2O2 and its molecular weight is 170.21. It is chemically unrelated to any of the other antiepileptic drugs. It is a white to off-white powder with a faint odor and bitter

Clinical Chemistry When people consider their careers in the health care field‚ most of them would think about being a physician‚ a nurse or a surgeon. Individuals with interest in the health care field are not aware of clinical laboratory science. I am one of those individuals who don’t know much about clinical laboratory science before. After taking the class “Introduction to Clinical Laboratory Science”‚ I start to realize that clinical laboratory scientists are just like other health care members

sodium‚ it will reduce the plasma volume and thus reduce the blood pressure (Widmaier‚ Raff & Strang 2001). The change in blood pressure will be detected by baroreceptor and initiate reflexes that influence the renal arterioles and tubules to reduce glomerular filtration rate (GFR).Renal cells secrete renin that indirectly cause adrenal cortex to increase aldosterone secretion. Increasing in aldosterone will stimulate cortical collecting duct to increase sodium reabsorption and reduces sodium excretion

SUMMARY Chronic renal failure (CRF) is the progressive loss of kidney function. The kidneys attempt to compensate for renal damage by hyperfiltration (excessive straining of the blood) within the remaining functional nephrons (filtering units that consist of a glomerulus and corresponding tubule). The cause for CRF sometimes can be determined by a detailed medical history‚ a comprehensive physical examination‚ and laboratory studies. CRF are common in patients who have multiple myeloma ( cancer
