New Oauses of Obesity

obesityA new cause of obesity linked to an abnormality on chromosome 16 has been highlighted. It explains about 1% of cases. These works are a collaboration between the Lille team (1) Professor Philippe Froguel, a researcher at the CNRS, associated closely with colleagues at Imperial College London and University Hospital Center of Vaud in Lausanne and ten other groups European research. They will be published Thursday, February 4 in the journal Nature. They open new perspectives for targeted preventive treatment.

The international team focused on the role played by the absence of a small fragment of chromosome 16 in the onset of a severe form of obesity. This anomaly more accurately called “microdeletion” (loss of a fraction of chromosome) causes the deletion of thirty different genes in this region. Researchers have discovered that this microdeletion, absent in most individuals, is quite common among the obese. They believe that the risk of developing severe obesity is greater than 5.000% for individuals carrying a deletion of chromosome 16. “If the identity of the genes responsible for obesity remains to be determined, it is likely that these genes play a role in brain development,” they note, because this chromosomal region is known to be linked to development of schizophrenia and autism, two diseases often complicated by obesity. These results also confirm the link between obesity and neuropsychiatric diseases.

But “obesity is multifactorial origin,” say the authors of that work. “It involves several genes, becoming better known, and environmental factors. Even if the increase in the number of overweight people has societal causes are easily identified (sedentary, food …), heredity plays a crucial role in determining the weight and the onset of obesity. Recent studies have revealed the involvement of thirty genes that increase the risk of obesity so low or moderate (increase of only 10 to 50% per gene).

Causes Of Migraine

migraineThe main culprits

Migraine is caused by a malfunction of the vascular and nervous systems. And certainly, the disease is a family affair. Here’s what we know because of migraine. In other words, little things. More is known about the events that trigger the crisis, once installed migraine.

Situation 1: no breakfast.

The main reasons given are:

* 1. no time.
* 2. Not hungry.

1. Lack of time is not a valid reason. You can always find. Everything depends on the importance you attach to this breakfast. If you admit that it is important to you, you’ll find the time that you need.

But suppose, since we are here to speak specifically, you are totally overwhelmed (e) in the morning. What time ‘t grant you? 10 minutes? 5 minutes? 5 minutes without running.

Varicose Veins: which treatment to choose?

VaricesNew techniques of treatment of varicose veins have emerged and are increasingly used. Sclerotherapy, laser, Chiva, What are the results of these interventions lighter than surgery? A report of Anaes an update on the issue.

Varicose veins and tired legs are very frequent diseases. It is estimated that three out of four people have varicose veins during their lives and for one in four symptoms are bothersome enough to warrant medical treatment or surgery. In recent years, techniques have improved and new methods have emerged, promising treatments lighter and in theory less traumatic. But what are their real benefits? The answer with experts from the National Agency for Accreditation and Health Evaluation (Anaes).

Shoo reflux

To understand the techniques employed, some anatomical details are needed. The blood flow in the legs in a deep venous network, located in the heart muscle, and in a superficial network, under the skin. This superficial network is affected by varicose veins. It comprises two main veins, both large and small saphenous, who bring a game of blood into the deep network, and secondary veins, smaller. To prevent the stagnant blood in the superficial veins, antireflux valves are distributed throughout their journey. In case of failure of these valves, reflux occurs and the vein is dilated, forming a varicose vein visible under the skin. Read the rest of this entry »

How to treat dry skin?

dry skinYou are likely to have this problem will diminish with age … This is the most sensitive skin to treat because it is halfway between the dry skin and oily skin. Moreover, it was too inclined to regard as “normal” and we do not take time to heal.

What is your skin type?

skin care

We have every type of skin that is very specific rather difficult to define as it evolves over time depending on age, hormones, but also on external factors such as climate, temperature, heat, pollution The lifestyle … But to choose a cosmetic active to very specific, we must still define the physiology of our skin. Is it rather dry, oily, mixed, sensitive?

Type dry skin: Skin usually thin and beautiful, without pores, it is a source of tightness and discomfort. The reasons for dry skin are many. The stratum corneum lack of water, the hydro lipid film on the surface is too thin and no longer protects the skin, oil runs out …

Oily skin: Its grain is thicker, the pores are dilated and the general appearance of the skin is dull, oily and shiny. This skin type is conducive to buttons and black spots and excess sebum causes permanent long-term thickening of the stratum corneum. This skin can be both fat and lack of water, ie be dehydrated.
