This paper addresses the problem of human robot interaction with application to the design of assistive devices. We describe the design and development of a prototype of a smart wheelchair that can be commanded by a rider. Specifically, we focus on (a) the vision-based human interaction interface; (b) the suite of sensors on the chair; and (c) the software(More)
Primary intraosseous mucoepidermoid carcinoma of the jawbones is an extremely rare malignant salivary gland tumour constituting 2-4.3% of all the reported mucoepidermoid carcinomas. We report a case of intraosseous mucoepidermoid carcinoma of the mandible in an 80-year old female patient developing from a previously diagnosed dentigerous cyst. An excisional(More)
The presence of teeth at birth or within a month post-delivery is a rare condition. A newborn, a 2 days old female, with two mandibular incisor natal teeth was examined. The teeth were mobile and were extracted because of the fear of aspiration and refusal to feed. The purpose of this report is to review the literature related to natal teeth epidemiology(More)
Odontomas are considered to be hamartomas rather than a true neoplasm. They consist chiefly of enamel and dentin, with variable amount of pulp and cementum when fully developed. They are generally asymptomatic and are included under the benign calcified odontogenic tumors. They are usually discovered on routine radiographic examination. Eruption of an(More)
CONTEXT Inducible nitric oxide synthase (iNOS) is a cytoplasmic enzyme which plays a crucial role in the pathogenesis of oral carcinomas and sarcomas. AIMS The objective of this study was to analyze the immunohistochemical expression of iNOS in carcinomas and sarcomas affecting the oral cavity in order to understand the possible role of iNOS in their(More)
Oral lesions in neonates represent a wide range of diseases often creating apprehension and anxiety among parents. Early examination and prompt diagnosis can aid in prudent management and serve as baseline against the future course of the disease. The present review aims to enlist and describe the diagnostic features of commonly encountered oral lesions in(More)
In biology, cell death is a natural process, wherein the worn-out cells with declining function, are eventually removed from the organism. The three well-known mechanisms of cell demise are apoptosis, autophagy, and necrosis. The latest addition to this list is, still another pathway, recognized as " necroptosis. " 1 In contrast to the traditional believe,(More)
The majority of oral diseases present as growths and masses of varied cellular origin. Such masses may include simple hyperplasia, hamartoma, choristoma, teratoma, benign or malignant neoplasms. The distinguishing features of hamartomatous lesions are not certain, and often these non-neoplastic masses are indiscreetly denoted as neoplasms without weighing(More)
Mycoplasma represents a unique group of bacteria measuring about 0.2-0.8 µm in diameter. Due to the absence of a cell wall, Mycoplasma varies in size and shape. A number of these Mycoplasma species such as Mycoplasma salivarium, Mycoplasma orale, Mycoplasma faucium, Mycoplasma buccale, Mycoplasma fermentans, Mycoplasma lipophilum, and Mycoplasma pneumonia(More)
BACKGROUND Keratins are the most abundant proteins and are characteristic findings in many epithelial pathologies, making it a diagnostically important marker, both histopathologically and immunohistochemically. Since, immunohistochemistry is an expensive diagnostic tool, special stains to detect the degree of keratinization could serve as a faster and(More)
