Un inventaire faunistique est proposé pour la totalité des espèces de scorpions connues d'Algérie. L'objectif de la présente contribution est de proposer une checklist actualisée de toutes les espèces répertoriées pour ce pays comme nous l'avons effectué pour le Maroc (Arachnides, 2017, n°83). Abstract. A faunistic inventory is proposed for the kno...
Established human mammary tumor cell lines constitute an important tool in the study of breast cancer. The aim of this work was to isolate and characterize two new mammary tumor cell lines, JCK and GCS, which were obtained from the pleural effusion and ascitic fluid, respectively, from two breast cancer patients. Both cell lines had some properties...
We found an activated Kirsten (Ki)-ras gene in the MDA-MB-134 breast carcinoma cell line by transfection of NIH3T3 cells. Oligonucleotide hybridization demonstrated that this cell line carries a single G to C point mutation at position 12 leading to a glycine-arginine substitution. However, only a fraction of the cell population seems to contain th...
Messenger RNAs from mouse brain hemispheres and from an enriched astroglial population of the same area were isolated, characterized and used to study Glutamine Synthetase (GS) processing during postnatal development using a m-RNA stimulated reticulocyte lysate system. The RNA preparations yielded distinct polypeptide products upon translation incl...
Astroglial cells in primary cultures bind [3H]flunitrazepam with a high affinity on a single type of site and on a number of binding sites which increased during astroglial growth and differentiation. These binding sites show a particular pharmacological spectrum characterized by an inhibition of high affinity by RO-5-4864 (4'-chlorodiazepam), an a...
The gamma-glutamyltransferase (gamma-GT) activity decreased by 50% following adrenalectomy of female rats, in homogenate as well as in a purified plasma membrane preparation from liver. In contrast, such a variation was not found in the kidney. None of 3 other enzyme activities of the plasma membrane, namely 5'-nucleotidase, alkaline phosphatase, a...
