Control of the operated carotid with ultrasound. Anatomical and hemodynamical modifications, both local and intracranial.

Background: A study has been done on the operated carotid monitoring the modifications of the wall and of the flow in the site of the operation and at the intracranial level.

Methods: 146 operated carotids were studied using transcranial Doppler, duplex and color. The pre-surgical data were confronted with the postsurgical ones on the 4th day, one month later, 3 months later and every 6 months.

A new classification of varicose veins to compare various surgical strategies.

Considering the presupposition that chronic venous insufficiency (CVI) and varicose veins classifications are extremely difficult, and that none of those presently in use are sufficiently complete, the authors propose the classification of the haemodynamic venous disease (HVD) and of the varicose veins from the clinical, anatomotopographical, etiopathogenetical and haemodynamical point-of-view. This type of classification allows us to closely follow the disease's evolution, to distinguish the benign forms from the more aggressive ones, and to evaluate the results of the medical, surgical and schlerotherapical treatments, from the efficiently, functional, instrumental and aesthetically point-of-view.

Nucleotide sequence analysis of a mouse Y chromosomal DNA fragment containing Bkm and LINE elements.

The strong suppression of crossing-over between the X and Y chromosomes permits rapid accumulation of repetitive sequences in the Y chromosome. To gain insight into the mechanism responsible for the sequence amplification, it is essential to characterize Y chromosomal repetitive sequences at the molecular level. Here, we report the entire nucleotide sequence (3,902bp) of AC11, a mouse sequence that is repeated 300 times in the Y chromosome.
