Response of rats to dose rates of ionizing radiation evaluated by dielectric properties of bone marrow.

The response of adult Wistar albino female rats toward two dose rates of gamma radiation delivered as acute dose of 7 Gy is investigated using classical methodologies as chemical, hematological and histological parameters in comparison with newly introduced dielectric parameters. Two groups of rats were exposed to γ ray with dose rates 533.35 mGy/min and 325.

Cloning and characterization of some rep20 DNA fragments from the genome of the human malaria pathogen Plasmodium falciparum.

Chromosomes of the human malaria parasite Plasmodiumfalciparum contain long subtelomeric repeat sequences and little is known about them. In this study, we have cloned 10 fragments of the non-coding rep20 sequence from the genome of Plasmodium falciparum 3D7 and HB3 strains. Analysis of these fragments showed that they represent 4 different 3D7 fragments and 2 different HB3 ones.
