When our body is not able to regulate temperature all our body functions will fail to work. Even the enzymes need a specific constant temperature to work at their optimum level. At higher temperatures the enzymes will stop working. Dialysis is the artificial process

PHYSIOLOGY Transmembrane receptors composed of excitable G-proteins‚ which cross the cell membrane and link selectively with extra cellular ligands are called adrenoceptors. They are also termed as α-2 Adrenoceptor agonists α-2 adrenergic receptors. Three α-2 isoreceptors - α-2a‚ α-2b and α-2c of adreno receptor bind α-2 agonists and antagonists with similar rapport and share an amino acid composition homology of roughly 70 to 75%. The efficacy of sub receptor specific agonists that constrains deleterious

The body health depends in keeping body fluid in balance‚ which distribute between intravascular in blood vessels‚ and extravascular which can be inside the cell (intracellular fluid) or between the cells called (interstitial fluid). Edema occurs when the interstitial volume has increased due to fluid leaks from capillaries or tiny blood vessels to interstitial space‚ then the space will expand cause edema.[1] To understand the mechanism clearly‚ fluid dynamic control should be considered‚ the hydrostatic

According to CDC‚ heart disease is the leading cause of death in women who are 25 to 44 yrs old2. Maternal cardiac disease in a pregnant woman can present challenges in cardiovascular and maternal-fetal management thereby leading to significant non-obstetric

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
