Cell biology, disease susceptibility and innovative therapeutics

Article Abstract:

The health of oral tissues, the progression of disease, and the outcome of dental therapeutic processes depends substantially on the health of tissues at the cellular level. Every living thing is composed of minute cells, each of which carries the entire human genetic code. Researchers in molecular biology and genetics have identified many of the 100,000 human genes. Identification of gene functions and their associations with disease and health have facilitated the production of drugs and processes that alter gene expression, promoting health and arresting disease progression.

Toward `molecular gastronomy,' or what's in a taste?

Article Abstract:

The human mouth contains about 10,000 taste buds, mostly on the tongue. All taste buds can detect more than one type of taste among the five basic tastes: sweet, sour, salty, bitter and umani. Taste buds in turn contain between 50 and 150 taste receptor cells. Additional research has revealed two genes that produce taste receptor cells: TR1 and TR2. TR1 is mostly located in taste buds on the front of the tongue whereas TR2 is located in taste buds in the back. These are the cells that are activated by nutrients in food.

The A,B,C,D and E of viral hepatitis

Article Abstract:

Dental professionals may have a high risk for acquiring viral hepatitis through exposure to patients' blood. There are five types of hepatitis: hepatitis A, B, C, D, and E. The various types of hepatitis may be diagnosed through blood tests. The only known treatment for viral hepatitis is bed rest, good diet, and abstinence from alcoholic drinks. Dental workers should be immunized against hepatitis B and possibly against hepatitis A. Hepatitis exposure can be minimized by using barrier protection.
