Draft of a position glare that free when pyramidal the nervous centers cannot more carry out their task, or they have not still begun to carry out it (as in the child before the six months); the phenomenon of Magnus can be had also during a serious hemiplegia of cerebral origin.

Fortunately the means and the drugs in order to fight on being born the atherosclerosis are famous from many years. The more difficult and hard part is in making to revert the disease after its appearance in nsotro the organism. However lowering the levels of LDL (bad cholesterol) increasing to those of HDL (good cholesterol) and with drugs today on hand is optimal possibilities of a reduction nearly completes dele aterosclerotiche plates. But like it is made to understand when the ill-famed plate is indeed diminishing in thickness? Today finally we are in a position to seeing not only the inside of the artery, but also the external wall of goes and the plate in its nearly totality, which can have different spessori and characteristics. Moreover nowadays, thanks to the echo-Doppler and other techniques much sophisticated (Tac and RMN) are resolutions to demonstrate that the treatments that they make “to melt” the plates, diminish also the cardiovascular events, like ictus and infarcts. The only plates that difficultly revert are those calcifiche, typical of the old.

Investigators of the Albert Einstein College of Medicines of the Yeshiva University di New York have characterized a cerebral enzyme, called p70 S6 kinasi, that the weight increase could carry out an important role in preventing. In a experiment, lead on rats, the level of the enzyme has been possible regular purposely uses with it of modified viruses. The rapes with a high level of p70 S6 kinasi have demonstrated an appetite reduction, weight and of molecules that normally stimulate the appetite of the animal. Moreover if subordinates to a ipercalorica diet the rats with a greater enzyme concentration endure a weight increase that happens very more slowly regarding the rats of control with a normal enzyme concentration. The obtained result make to assume that drugs directed on the regulation of p70 S6 kinasi could lead to encouraging result for the control of the obesity and other metabolic disorders.
The search has been published on Cell Metabolism.

The Philadelphia chromosome, the genetic anomaly to the base of the chronic mieloide leukaemia, is the result of the exchange and the union of two coming DNA segments from chromosome 9 and chromosome 22.
This process takes the name of mutual traslocazione. The new chromosome that form door the genetic instruction for a new protein, BRC-ABL, equipped of enzymatic activity (is a tirosina chinasi) in a position to inducing a uncontrolled proliferation of the leucemiche cells.
In fact gene BRC-ABL is always active and is in charge of a continuous globule production white men who accumulate themselves in the blood and the woven ones carrying to the typical clinical picture of the chronic mieloide leukaemia.
