The results of the investigations of both teams, announced by the journal Nature, are an important step in the search for safe treatments for the replacement of damaged tissue of any part of the body.

Properly handled by the scientists, skin cells take on the properties of stem cells from embryos normally so they can become any tissue in the body.

Previously it was only possible to create these induced pluripotent stem cells (initials in English: iPS) using viruses to insert four genes that perform the reprogramming.

But the modified virus DNA in the cells so that increased the risk of cancer, so the technique was too risky for use in human patients.

Another danger that existed was that the changes caused by genes would lead to developmental abnormalities.

But now, scientists have managed to avoid the use of viruses and remove genes once they have fulfilled their task.

British and Canadian teams were able to insert four genes into a single segment of DNA to carry out the necessary reprogramming and then removed before they could cause damage.

The technique, described in the Internet version of Nature, was carried out both in skin cells in people as laboratory mice.

Tests carried out indicate that the reprogrammed cells behave exactly like stem cells from embryos.

This allows scientists to think more seriously about the possibility of using this type of pluripotent cells to replace tissue in people suffering from diseases or as yet incurable.

These cells may eventually become brain cells, insulin-producing pancreatic cells in bone or cartilage, heart muscle or other tissue of the human body.

Coming from the cells of the patient’s own skin would be resolved step the problem of rejection.

The cells are much more versatile embryonic stem cells “adult”, which have limited application.

The two teams who have collaborated in this work are one of the Center for Regenerative Medicine at Edinburgh University, led by Keisuke Kaji, and a Canadian University of Toronto, led by Andras Nagy.

“This new method will advance the field of regenerative medicine and will help us to understand many diseases and to test new drugs,” said Dr. Kaji.

“It has taken a step toward the practical use of reprogrammed cells in medicine, perhaps eliminating the need to use human embryos to obtain stem cells,” added the expert.

The four genes needed to create the iPS cells are c-Myc, Klf4, Oct4 yXox.

As soon as these genes reprogrammed cells, the scientists removed before they could cause interference with other genes.

This problem is solved in turn Canadian scientists led by Dr. Nagy, who managed to remove genes without a trace.

The director of the Center for Regenerative Medicine of Medical Research Council UK, Ian Wilmut, warned that it will pass some time before they can be given to patients with the iPS cells, they need to develop a method capable of generating different types of cells from the skin.

With this invention seeks to reduce the incidence of skin cancer. “The software determines the maximum recommended exposure to solar UV radiation, including the use of protective creams for people with different skin types displayed at any time and day of the year,” he told EFE Ruben Piacentini, director of Institute of Physics of the Argentina’s Rosario city (IFIR), which developed the project.

According to Argentine newspaper Infobae, the system can be installed on any computer and was created with the collaboration of researchers from the University of Innsbruck, Austria, Argentina and the Foundation Skin Cancer.

How to use

For information, the user must enter your skin type, the kind of surface you are (sand, water or cement), time of day and geographic location in which you, as the height or snow can increase the risk of radiation by 60 percent.
Sunbathing die trying

The software was designed to calculate the data anywhere in Argentina, although “you can develop a similar application for another country or region, with the right information,” says Piacentini.

In fact, IFIR has already started negotiations with regional governments and organizations in Ecuador and Brazil to implement the program called UVARG (software for predicting sun exposure in Argentina).

Advantage

“The software allows us to know instantly and in real time the danger of ultraviolet radiation, but also can be predicted months in advance what will be the risk, making it a useful tool to plan vacations to any destination” said the scientist.

Another use would be for employees who perform abroad, because the system tells them what protections they should take.

The system also alerts “on special situations such as the development of the ozone hole or about significant changes in the average value of this layer in future years,” says Piacentini.

The scientists who developed this software tool say that if people respect the times suggested sun exposure reduces the risk of diseases like skin cancer.

Today this evil is the most common cancers and the number of cases is growing at a rate of 5 percent annually, according to international statistics.

Meanwhile, in Argentina each year 600 people die from the disease and are detected 1400 new cases, according to the Sociedad Argentina de Dermatología (SAD).

Special Features

1. Are clinically measurable or quantifiable, because the stimuli that cause so are to play in the diagnosis.

2. They tend to be immediate (onset in minutes) and short (after an hour tend to disappear). As an exception we delayed pressure urticaria.

3. In the majority of cases are located at the site of stimulation.

4. They tend to be reproducible challenge test clinically well defined, which makes diagnosis and control. Physical Urticaria

5. They usually affect young adults, with a preference for females.

6. Manifest no obvious triggers v tend to resolve spontaneously over time, except in family forms (very rare).

7. The etiology or cause is unknown, although some associations with other diseases. There is a higher incidence of family or personal atopy. Some have a genetic basis or relative, the majority of autosomal dominant transmission.

8. Among them are associated with some frequency, and also with other types of urticaria.

9. Angioedema may occur in cold urticaria, pressure, vibration and more rarely, cholinergic.

10. With light stimuli presented clinical Mild itching or erythema isolated.

Physical Treatment of Hives

Generally should be avoided triggering mechanisms.

As drug treatment used second-generation antihistamines (Loratadine Cetirizina.. Ebastine. Mizolastine. Fexofenadine), if no improvement is through the first generation such as hydroxyzine, or an antidepressant effect in urticaria as doxepin is.

The face is usually the part of the body that we put more attention women. As soon as each

day dawns, the first thing we do is we touched the face and feel the softness of women and immediately we’re going to look in the mirror closest we have to verify if dawned beautiful, or if one was born a small imperfection in which, throw to kill us, shouting at the sky:

“Oh no …” I woke up swollen face, “” What I have horrible dark circles “…” How pale I am … what gaunt “,” There are bumps and fed me “,” What greasy, or what is my skin dry “” Why do I get hair on his chin? “” I is coming out acne “,” How to strike me these little black dots on the nose “” I have cloth on the face, what I look ugly today “” I hate my long face, or flat, “” Why not me I got these blackheads yesterday? “… if the squashed me right now, I look very ugly, they will laugh at me”, etc..

Concern over his face. She usually never happy with your face and the conditions in which it is located, is always looking flawless and perfect look, and it was going most of the day or night carefully watching him … And even Moors seeing machete!.

Some women until approaching a magnifying glass to make sure your pores are closed, or by observing that the eyebrows are well symmetrical, and many other women, instead of appreciating the beauty of her oval face, square look to it … What a joke have to say so!.

Beauty, face, makeup, skin. Each woman has their own type of skin, and not always the one that is desired. Some truly strive to delineate their best to highlight our factions and embellish it with one or a thousand shades, powders and blushes, shadows, lip pencils, markers, mascara and even false eyelashes in or contact lenses , which often end up leaving so irritated eyes and red as a bold enchantress.

Why women worry so much over her face and man?

This is not normal. Women have an advantage over men. They can not cover imperfections with makeup daily, and can not afford to be looking in a mirror every minute like us, that already, seeing us all day in a mirror, we become a habit and a millennial true ritual required.
