We have cloned and sequenced the C-kappa (Ck) genes from seven species and subspecies of rats which have diverged over the past few million years in Australia. Comparisons of these sequences with each other and the Ck genes of the laboratory rat, Rattus norvegicus, indicate noncoding regions have accumulated fewer mutations than adjacent coding sequences,(More)
We have determined the nucleotide sequence of a 1,200-base pair (bp) genomic fragment that includes the kappa-chain constant-region gene (C kappa) from two species of native Australian rodents, Rattus leucopus cooktownensis and Rattus colletti. Comparison of these sequences with each other and with other rodent C kappa genes shows three surprising features.(More)
Ameloblastic carcinoma is characterized by rapid, painful expansion of the jaw, unlike conventional ameloblastoma. The tumor most frequently involves the mandible. The expanding lesion causes perforation of buccal and lingual plates of the jaw and invades the surrounding soft tissue. Rapidly growing large tumor mass may cause tooth mobility. Mandibular(More)
We have isolated a region containing the immunoglobulin kappa chain joining segments from a liver DNA library of the Australian rat Rattus villosissimus, and determined its nucleotide sequence. While the laboratory rat (Rattus norvegicus) had previously been shown to contain three recently duplicated copies of J kappa 2, R. villosissimus has only two.(More)
Adenoid Cystic Carcinoma (ACC) is a rare tumor constitutes for less than 1% of head and neck malignancies and 10% of all salivary gland tumors. Palate is the most common site to be involved in the oral cavity followed by parotid gland and submandibular gland. They are usually asymptomatic, slow growing, characteristically shows infiltrative growth and(More)
Trigeminal Neuralgia (TN) is considered as one of the most painful neurologic disorders affecting oro-facial region. TN is often diagnosed clinically based on the patients complete history of pain (severity, duration, episodes etc), relief of pain on test dose of Carbamazepine, regional block of long acting anaesthetic. However, Magnetic Resonance Imaging(More)
We have isolated a region containing the immunoglobulin kappa chain joining segments from a liver DNA library of the Australian rat Rattus villosissimus, and determined its nucleotide sequence. While the laboratory rat (Rattus norvegicus) had previously been shown to contain three recently duplicated copies of J κ 2, R. villosissimus has only two.(More)
