We present an algorithm for layer-specific edge detection in retinal optical coherence tomography images through a structured learning algorithm to reinforce traditional graph-based retinal layer segmentation. The proposed algorithm simultaneously identifies individual layers and their corresponding edges, resulting in the computation of layer-specific(More)
Oral cancer (OC) is the sixth most common cancer in the world. In India it is the most common malignant neoplasm. Histopathological images have widely been used in the differential diagnosis of normal, oral precancerous (oral sub-mucous fibrosis (OSF)) and cancer lesions. However, this technique is limited by subjective interpretations and less accurate(More)
AIM This study aims to develop a novel noninvasive method for early cancer trend diagnosis in habitual smokers by corroborating cytomorphological and autofluorescence alterations. MATERIALS & METHODS A total of 120 subjects were included and categorized into nonsmoker, smoker and clinically diagnosed oral potentially malignant disorder (OPMD) patients.(More)
The effects of chronic polychlorinated biphenyl (PCB) compound toxicity on L-ascorbic acid metabolism in rats have been studied. PCB treatment brought about a depression in the activities of the enzymes L-gluonolactone oxidase and dehydroascorbatase along with an increased tissue levels and urinary excretion of L-ascorbic acid. PCB toxicity drastically(More)
1. Lead toxicated rats became severely anaemic which could be recovered to a considerable extent by simultaneous supplementation of L-ascorbic acid to these rats. 2. The concentrations of L-ascorbic acid in the liver tissues and in the urine of the toxicated rats were increased significantly while that in the kidney tissues was markedly reduced and(More)
The invention is inspired by the desire to understand the opportunities and expectations of developing economies in terms of healthcare. The designed system is a point-of-care (POC) device that can deliver heart-care services to the rural population and bridge the rural-urban divide in healthcare delivery. The product design incorporates several innovations(More)
Honey is known as a popular healing agent against tropical infections and wounds. However, the effects of honey dilutions on keratinocyte (HaCaT) wound healing under hypoxic condition is still not explored. In this study, we examined whether honey dilution have wound healing potential under hypoxic stress. The antioxidant potential and healing efficacy of(More)
Microscope optics presents two critical limitations of low depth of field and very low or no depth perception. Due to low depth of field, at high magnification levels microscope cannot adequately focus on the object. This can adversely affect the performance of slide digitization procedure in digital pathology. This paper presents a depth of field extension(More)
