In vitro interaction of cyclooxygenase-2 inhibitors with radiation in nasopharyngeal carcinoma cell line: Dependence on sequence of administration
In nasopharyngeal carcinoma (NPC), COX-2 inhibitors have been reported to exhibit dose-dependent growth inhibition of these cancer cells, but their interaction with radiation has not yet been studied. Here, we examined the effects of selective COX-2 inhibitors SC-236 and NS-398 on the radiosensitivity of NPC cells. When incubated with COX-2 inhibitors prior to ...
The effect of using combination chemotherapy in colorectal cancer in India: A single institute survey
The incidence of colorectal cancer in India is on upward swing due to the change in dietary habits. This study was done to evaluate the efficacy of two commonly used regimens. In this study, colorectal cancer patients treated with adjuvant chemotherapy from 1997 - 2001 were included and followed up for a period of five years. The efficacy of the commonly used regimens was compared in terms of five year disease free...
An improved implementation of brain tumor detection using segmentation based on soft computing
Image segmentation is an important and challenging factor in the medical image segmentation. This paper describes segmentation method consisting of two phases. In the first phase, the MRI brain image is acquired from patients database, In that film, artifact and noise are removed after that HSom is applied for image segmentation. The HSom is the extension of the conventional self organizing map used to classify the...
