Ⅰ. 서론
갈수록 건강에 대한 관심이 고조되어 가는 가운데, 그 원인을 식품에서 찾으려는 노력들이 현재 나타나고 있다. 이로 인해 과거 전 세계적으로 비만인구와 각종 성인병의 주범이 되었던 패스트푸드를 경계하게 됨과 동시에 슬로우 푸드를 지향하는 추세이다.
슬로우 푸드란 맛의 표준화
1. Background
Scent: Odor
The sense of smell gives rise to the perception of odors, mediated by the olfactory nerve. The olfactory receptor (OR) cells are neurons present in the olfactory epithelium, a small patch of tissue in back of the nasal cavity. There are millions of olfactory receptor neurons that act as sensory signaling cells. Each neuron has cilia in direct contact with air. The
5.2 Drug Delivery System
5.2.1 Advantage of Nano-drug delivery system
By diagnosis, and for treatment, we need enhanced drug delivery system. Drug delivery system of these days is just eat and let it flow through the body. It is not good at efficiency. Because the digestive system sometimes digest and remove the drug before it reaches to the target.
For enhancing the efficiency of drug
rRNA는 리보솜 단백질과 함께 뭉쳐 리보솜을 만드는 물질
rRNA의 역할은 리보솜이 mRNA에 붙도록 도와주고 해독을 돕는 역할
16S rRNA의 구조는 일관되고 필수적인 역할 때문에 16S rRNA의 특정 부분은 진화 속도가 매우 느려 많은 염기 서열이 보존 됨

Lipopolysaccharides (LPS), also known as lipoglycans,
are large molecules consisting of a lipid and a polysaccharide
joined by a covalent bond; they are found in the outer
membrane of Gram-negative bacteria, act as endotoxins and
elicit strong immune responses in animals.
LPS is the major component of the outer membrane of
Gram-negative bacteria, contributing greatly to the structu

The severity of the symptoms depends on the adequacy of collaterals

43)튜렛 증후군(Tourette syndrome)
(1) 튜렛 증후군이란?
튜렛 증후군은 경련(tics)이라 불리는 음성 통제불능과 반복된 무의식적 행동에 의해 특성화된 신경장애로 유전된다. 몇몇 경우에서 쓰는 부적절한 단어와 문장을 사용한다. 이병은 일반적으로 18세 전에 발생한다. 튜렛 증후군은 모든 민족에서 발
