Organic Chemistry Anti Inflammatory
2,348 wordsWhat would you think if I gave you a drug and said this is going to help you but I want you to know ahead of time that 50 % of the dose is not affected, in fact the drug is 50 % not pure. The idea of that would make you feel you want another drug. The reality of that is that a large # of drugs we give are 50 % impure and the reason is b / c so many drugs we give are racemic mixtures, a 50: 50 mixture of enantiomer's. Most drugs that demonstrate optical activity only one isomer is pharma logicall...

1,611 wordsPg. 8 LSD Longo-Vega To understand the ways that LSD affect the brain we must first discuss how the brain sends signals to the body. In the brain and the brain stem there are special cells called neurons. Neurons release a number of chemicals that are sent to various receptors. The receptors interpret chemical signals and use them to make you move, see, hear, learn, etc. These neurons are also responsible for such behaviors as obsessive-compulsive behavior and insomnia. The cells that are direct...

Shown In Figure Neuromuscular Junction
1,660 wordsProteins involved in formation of the neuromuscular junction The neuromuscular junction is a specialized junction, where a motor nerve forms its synaptic terminal with a muscle fibre, one of many fibres that make up a whole muscle. The mature neuromuscular junction is composed of three types of cells - a motor nerve terminal, a muscle fibre and a Schwann cell covering the junction. All three of these cells are highly differentiated and specialized for their functions (Kandel 2000, p. 1089). The ...

Second, 'psychotomimetic effects similar to those induced by PCP can be induced by ketamine, a related arylcyclohexamine derivative' (Sevvenson, 1995). This is a particulary strong point of evidence, especially when coupled with the following point: A dosage of ketamine ten times that of PCP is required in order to induce the same effect (Halberstad, 1995).

This classification is not definitive in including all proteins, since there may well be other examples that span the membrane with different numbers of anchor chains. The structure of proteins varies greatly. The first factor affecting structure is the proteins function, but equally important is the proteins location, a...

Some of these enzymes break down proteins, others attack fats, and still others disassemble the nucleic acids that make up DNA and RNA (Bourne, 1992, p. 123). Lynosomes don't always work right. When they fail, the result can be catastrophic disease. In Tay-Sachs disease, for example, victims have inherited a faulty gene, which leads to a defective enzyme or no enzyme at all. As a result certain undigested molecules accumulate in the lysosomes, gradually lead...

Muscular Dystrophy Association Skeletal Muscles
759 wordsIn 1890, German medical professor Wilhelm Erb and other physicians had been observing several cases of a neuromuscular disease that they believed was affecting how nerve impulses were transmitted to muscle at the neuromuscular junction. The patient? s experienced a " grave muscular weakness" and Wilhelm named it myasthenia gravis. Through further research, the physicians discovered whether it affected the eye muscles first, or created difficulty in talking, chewing and swallowing, or i...
