OBJECTIVES Toll like receptors play an important role in innate and adaptive immune responses. Heat shock proteins play a significant role in cell proliferation, differentiation and oncogenesis. HSP70 acts as one of the ligands of TLR4 and binds to it in a CD14 dependent fashion to bring about proinflammatory cytokine production leading to an anti-tumor(More)
Toll-like receptors (TLRs) play an essential role in the activation of innate immunity. TLRs are expressed in B-lymphocytes, monocytes, dendritic cells and epithelial cells. We examined the immunohistochemical expressions of TLR4 and TLR9 in various grades of oral epithelial dysplasia (OED), oral squamous cell carcinoma (OSCC) and normal oral mucosa (NOM)(More)
There is increasing evidence of a causal association between human papillomavirus (HPV) and oral squamous cell carcinoma (OSCC). Several studies have shown that HPV is associated with increased risk of oral cancer independent of exposure to tobacco and alcohol. The association is valid for HPVs 16 and 18, which generally are considered high risk types,(More)
Analysis of apoptotic cells in oral pathological states could be useful for determining the rates of tissue turnover, which would help determine prognosis. The use of histochemical stains such as hematoxylin and eosin (H & E) and methyl green-pyronin (MGP) can provide a simple and cost-effective method for detecting apoptotic cells. We compared the efficacy(More)
BACKGROUND Cytogenetic studies from past decades have shown that interphase cells of female cats contain a densely stained chromatin mass in their nuclei called as Barr bodies (BBs) named after the scientist Murray Barr. BBs are unique chromatin structures formed due to the condensation of the X-chromosome. Many psychopathic disorders originate from(More)
Dental anatomy is the study of morphology of various teeth in human dentitions. The application of dental anatomy in clinical practice is important, and dentist should have a thorough knowledge regarding the morphology of the teeth. At times as a result of genetic variation, environmental factors, diet of an individual and race, variations in the morphology(More)
Nodular fasciitis (NF) is a benign tumor that grows extending from the muscular fascia to the subcutaneous tissue and, less frequently, into the underlying muscle. The cause of such proliferation is unknown, although trauma is believed to be important because of the location of these lesions over bony prominences. NF can often be confused with(More)
Background. The most common species isolated from primary endodontic infections are black-pigmented bacteria. These species are implicated in apical abscess formation due to their proteolytic activity and are fastidious in nature. Therefore, the present study was carried out to evaluate the presence and identification of various pigmented Porphyromonas and(More)
