in the formation of prostanoids. Prostanoids areformed by most cells and act as autocrine and paracrine lipid mediators. They are not stored but are synthesized de novo from membrane-released arachidonic acid mobilized by phospholipases (PLA2) when cells are activated by mechanical trauma, cytokines and growth factors, etc. Conversionof arachidonic acid to prostanoid endproducts is carried out by
Ⅰ. 뇌질환과 외상성뇌손상
뇌의 기능이 서로 연결이 되어 있어 손상 시 고유의 담당 기능뿐만이 아니라 연결하는 통로의 역할도 손상을 입게 되어 다양한 증상을 나타내게 된다.
외상성 뇌손상(traumatic braininjury)의 병태 생리는 외상 시 충격으로 즉시 나타나는 일차적인 손상(primary injury)과 뇌손상

slightly thinner and elongated than B-DNA conformation.
The conformational change readily occurs in alternating Purine and Pyrimidine sequence.
Z-DNA is a higher energy conformation than B-DNA (ΔG near +4kcal/mol)
The roles of Z – DNA in biologic system are not clearly identified and an area of active study.

in preserving its value as food.
Preservation usually involves preventing the growth of bacteria, fungi, and other micro-organisms, as well as regarding the oxidation of fats which cause rancidity. It also includes processes to inhibit natural aging and discoloration that can occur during food preparation such as the enzymatic browning reaction in apples or potatoes, etc. Some preservation metho
