Nobel Prize of Medicine 1997

Nobel Prize of Medicine 1997
Stanley B. Prusiner for his discovery of Prions - a new biological principle of infection

Stanley B. Prusiner was born in 1942 in Des Moines, Iowa, USA. Since 1968 he has been a professor in neurology, biochemistry, and virology at the University of California in San Francisco, and in Berkeley.

Prusiner won the Nobel Prize in Physiology or Medicine in 1997 for his work proposing an explanation for the cause of bovine spongiform encephalopathy ("mad cow disease") and its human equivalent, Creutzfeldt-Jakob disease. In this work, he coined the term prion, which comes from "proteinaceous infectious particle that lacks nucleic acid" to refer to a previously undescribed form of infection due to protein misfolding.

Gabriel Garcia Marquez

Gabriel Garcia Marquez Biography

Gabriel García Márquez was born in 1928 in the small town of Aracataca, situated in a tropical region of northern Colombia, between the mountains and the Caribbean Sea. He grew up with his maternal grandparent - his grandfather was a pensioned colonel from the civil war at the beginning of the century. He went to a Jesuit college and began to read law, but his studies were soon broken off for his work as a journalist. In 1954 he was sent to Rome on an assignment for his newspaper, and since then he has mostly lived abroad - in Paris, New York, Barcelona and Mexico - in a more or less compulsory exile. Besides his large output of fiction he has written screenplays and has continued to work as a journalist.

Biology::Procces of Tissue Repair

Procces of Tissue Repair
by Jonathan Ortega & Sueli Skinner

Tissue: Definition

A tissue is a group of cells that usually have a common embryonic origin and function together to carry out a specific task. Structure and properties of tissues are influenced by the extracellular fluids around the cells and types of cell junctions that are present. The study of tissues is called Histology.

žTissue Repair
Epithelial tissues and
most connective tissues have a continuous capacity for renewal. In some instances, undifferentiated cells called Stem Cells divide and replace lost and damaged cells. Stem cells are found in protected locations in the skin and gastrointestinal tract. Stem cells in bone marrow continually provide red and white blood cells. Stem cells called satellite cells are present in muscle tissue, but they divide too slowly for tissue repair. Smooth muscle cells may proliferate, but still too slowly for replacement of damaged tissues. Stem cells in brain tissue generally do not undergo mitosis to replace damaged tissue.

žScars sometimes result as tissues repair themselves. The process of scar tissue formation is called Fibrosis. Adhesions result from abnormal joining of tissues by scar tissues. Extreme adhesions developing after an injury may actually interfere with a tissue or organ’s ability to function properly.

žProper nutrition, blood circulation, and age may affect the rate of tissue repair. Healing processes place extra demands upon the body, so proper nutrition is vital to the healing process. Adequate protein must be present in the diet, and vitamins are essential for wound healing.

ž Vitamin A is essential for replacement and healing of epithelial tissues. B-vitamins are needed by cellular enzyme systems, and Vitamin C is essential for production and maintenance of collagen and development of new blood vessels. Vitamin D is needed for bone healing and formation, and Vitamin K is essential in the blood clotting process. Vitamin E may help prevent some types of tissue scar
