Un cas rare d'hémangiopéricytome malin du membre inférieur

L’hémangiopericytome est une tumeur vasculaire rare classée comme sarcome des tissus mous, elle peut être bénigne ou maligne, elle prend naissance au niveau des péricytes qui sont des cellules localisées au niveau de la lame basale de l’endothélium des capillaires ce qui explique son caractère ubiquitaire. Leur traitement de référence est la chirurgie souvent complétée d’une radiothérapie. Nous...

Some biological effects of volatile metabolites from cultures of Saccharomyces cerevisiae Meyen ex Hansen.

The gas mixtures from cultures of Saccharomyces cerevisiue inhibited growth and sporulation of Aspergillus niger and germination of seeds of Lepidium sativum. In test conditions seven volatile organic metabolites in the culture gases were identified by gas-liquid chromatography (GLC) as acetaldehyde, ethyl acetate, ethanol, n-propanol, isobutanoi, and a mixture of isopentanols (I part 2-methyl-...

Synaptic structures in the nuclei of sporulating yeast, Saccharomyces cerevisiae (Hansen).

After 4 h on speculation medium the larger cells have formed, within the nucleolus, a spherical body of amorphous substance which stains less densely than the nucleolus. At 8 h most of these bodies contain synaptonemal complex-like structures. There is usually only one such body per nucleus. Only rarely are normal synaptonemal complexes detectable in the nucleus. At the first meiotic division t...

Spindles, Spindle Plaques, and Meiosis in the Yeast Saccharomyces Cerevisiae (hansen)

The intranuclear spindle of yeast has an electron-opaque body at each pole. These spindle plaques lie on the nuclear envelope. During mitosis the spindle elongates while the nuclear membranes remain intact. After equatorial constriction there are two daughted nuclei, each with one spindle plaque. The spindle plaque then duplicates so that two side-by-side plaques are produced. These move rapidl...
