<p>The present study was performed to assess the genetic variations among six rabbit breeds in Egypt based on mitochondrial 16S rRNA sequences. The length of partial ranged from 546 bp 558 bp. sequenced regions were submitted GenBank/NCBI under accession numbers (MW052052 - MW052057). average content A+T 57% all breeds. Among breeds, percentages distance values 0.000 0.004. highest P-dist...

Our understanding of the pathogenesis mechanisms leading to lupus has been augmented by the analysis of several diff erent murine models over the past four decades. Various mouse models of spontaneous lupus have been employed in an eff ort to understand the cellular and genetic mechanisms behind induction of systemic lupus erythematosus (SLE). Th e classic models of spontaneous lupus include th...

New Zealand Black (NZB) and New Zealand White (NZW) mice are genetically predisposed to a lupus-like autoimmune syndrome. To further define the loci linked to disease traits in NZB and NZW mice in the context of the BALB/c genetic background, linkage analyses were conducted in two crosses: (NZW x BALB/c.H2(z))F(1) x NZB and (NZB x BALB/c)F(2). Novel loci linked to autoantibody production and gl...

Background: The mechanisms underlying cerebral hypercapnic vasodilatation are not fully understood. Objective: To investigate the role of nitric oxide (NO) and ATP-sensitive potassium (KATP) channels in basal blood flow regulation and hypercapnia-induced vasodilatation in rabbit cerebral blood vessels. Methods: The change in cerebral blood flow was measured by a laser Doppler flowmeter in 18 Ne...

To investigate changes in cellular gene expression associated with malignant progression, we identified differentially expressed genes in a cottontail rabbit papillomavirus (CRPV) squamous carcinoma model employing New Zealand White rabbits. The technique of suppression subtractive cDNA hybridization was applied to pairs of mRNA isolates from CRPV-induced benign papillomas and carcinomas, with ...

OBJECTIVE To investigate the pharmacokinetics and toxicity of intravitreal chemotherapeutic agents in the rabbit eye for the potential treatment of primary intraocular lymphoma and other intraocular malignancies. METHODS The ocular pharmacokinetics of intravitreal methotrexate sodium (400 microg) was studied in 10 New Zealand white rabbits, and a single-compartment, first-order elimination mo...

Previous studies have demonstrated the presence of apoprotein (apo) E protein and message in arterial lesions. To determine the source of the synthesized apoE, we performed simultaneous in situ hybridization and immunocytochemistry on human and rabbit atherosclerotic tissue. Studies of serial sections of aortic atherosclerotic lesions from humans and hypercholesterolemic New Zealand White rabbi...

F1 hybrids of New Zealand black (NZB) and New Zealand white (NZW) mice are a model of human systemic lupus erythematosus. These mice develop a severe immune com-plex-mediated nephritis, in which antinuclear autoantibodies are believed to play the major role. We used a genetic analysis of (NZB x NZW)F1 x NZW backcross mice to provide insight into whether different autoantibodies are subject to s...
