Amyloid peptide (Aβ) aggregation in the brain is a characteristic feature of Alzheimer disease (AD). Previously, we reported the discovery of focally elevated creatine deposits in brain tissue from TgCRND8 mice, which express double mutant (K670N/M671L and V717F) amyloid protein precursor. In this study, frozen hippocampal tissue sections from 5-, 8-, 11-,(More)
Odontogenic myxoma (OM) is a rare and locally invasive benign neoplasm found exclusively in the jaws. OM commonly occurs in the second and third decade, and the mandible is involved more commonly than the maxilla. The lesion often grows without symptoms and presents as a painless swelling.

The present study was aimed to characterize the type of conotoxin present in Conus parvatus. (CP) belongs to family conidae, through neuro-pharmacological activities of the crude venom extract on some of the CNS animal experiment using mice as animal model. The effects of CP on CNS were studied, by using spontaneous motor activity, gross behavior, rota-rod(More)
Most physical injuries resulting from abuse or violence are found on the head and neck areas that are clearly visible to the dental team during examination. Given that dental professionals routinely assess the head, face, and neck of patients, they are in a unique position to identify the signs of abuse and neglect. Involvement of a dentist in the(More)
