results the frequency of the baba2, icea1 and icea2 genes in the total isolates were 34 (54%), 14 (22.2%) and 34 (54%), respectively. the association of these virulence factors based on sex and age groups were not statistically significant (p > 0.05). there was a borderline significant association between icea1 and the clinical outcomes (p = 0.094). patients and methods in this study, 63 positi...

odontogenic tumors contain a heterogeneous collection of lesions that are categorized from hamartomas to benign and malignant neoplasms of inconstant aggressiveness. odontogenic tumors are usually extraordinary with assessed frequency of short of 0.5 cases/100,000 population for every year. the lesions such as odontogenic tumors are inferred from the components of the tooth-structuring contrapt...

CD8(+) T cells respond to signals mediated through a specific interaction between the T-cell receptor (TCR) and a composite antigen in the form of an epitopic peptide bound between the polymorphic α1 and α2 helices of an MHC class I (MHCI) molecule. The CD8 glycoprotein 'co-receives' antigen by binding to an invariant region of the MHCI molecule and can enhance ligand recognition by up to 1 mil...

The ability of transposable elements to mobilize across genomes and affect the expression of genes makes them exceptional tools for genetic manipulation methodologies. Several transposon-based systems have been modified and incorporated into shuttle mutagenesis approaches in a variety of organisms. We have found that the Mos1 element, a DNA transposon from Drosophila mauritiana, is suitable and...

Self-proteins are regularly processed for presentation to autoreactive T cells in association with both class I and class II major histocompatibility complex (MHC) molecules. The presentation of self-peptides plays a crucial role in the acquisition of T cell repertoire during thymic selection. We previously reported that the self-MHC class I peptide Ld 61-80 was immunogenic in syngeneic B10.A m...
