Dermatology: The art of purifying yourself through the skin

Among scientific specialties, dermatology is the one that closest to the precepts and techniques of cosmetological aesthetics. This is in charge of the study of the structure and functions of the skin and purifying the skin, in addition to treating the diseases pharmacologically. Dermatologists are doctors who, after completing the degree, which has an average duration of 4 years, specialize in dermatology and become suitable in diagnosing, preventing and indicating the most appropriate treatment. Skin diseases are sometimes isolated as vitiligo, however, on other occasions they are externalizations of internal ailments, as occurs in skin cancer and other conditions. In addition to knowing about infectious diseases, they must have knowledge of immunology, neurology, rheumatology and endocrinology. Cosmetic dermatology: It is a subspecialty of this branch of health that uses various techniques of cosmetics and appliances to treat scars left by acne using the laser, application of...

REGENERATIVE MEDICINE

Regenerative medicine is presented as a field of medicine with a revolutionary potential, offering the possibility of repairing or replacing damaged or sick tissues and organs by stimulating the body's own regenerative capacity or through the use of cells, tissues or biomaterials. This article aims to provide an overview of the concept of regenerative medicine, detailing its different types and objectives within the field of medical services. **FUNDAMENTAL CONCEPTS** Regenerative medicine is based on two fundamental pillars: * Regenerative capacity of the body:** The human body has an innate capacity to repair and regenerate damaged tissues. Regenerative medicine seeks to enhance this capacity through various strategies, such as stem cell stimulation or tissue engineering. * CELLS, TISSUES AND BIOMATERIALS:** Regenerative medicine also uses cells, tissues and biomaterials to replace or repair damaged or sick tissues. Stem cells, in particular, are of great interest du...

The culture of a Human Stem Cell laboratory

It was in 1981 when scientists first achieved mouse embryonic stem cell cultures. Although this milestone marked the development of numerous subsequent investigations, until 1998 the culture of a human stem cell laboratory was not achieved. In that year, two teams separately announced that they had isolated and cultivated human stem cells from, in one case, from embryos in the blastocyst phase and, in the other, from aborted fetuses. The research teams were led by biologists John Gearhart, from Johns Hopkins University, and James Thomson, from the University of Wisconsin at Madison. During the 1990s, scientists discovered many other characteristics of these cells, such as adult stem cells from a specific tissue (for example blood), can cause cells from other types of tissues, such as nerve cells (neurons). One of the most interesting results was obtained by researcher Fred Gage at the Salk Institute, who showed that the adult human brain can create new neurons. Before Gage...
