Induction of radioresistant nasopharyngeal carcinoma cell line CNE-2R by repeated high-dose X-ray irradiation
Background: All To enhance the curative effect of radiotherapy, we established a radio-resistant cell line, CNE-2R from CNE-2, a radio-sensitive type of CNE, through repeated irradiation. The developed cell line provides a basis for further studies on the radio-resistance of CNE and the molecular mechanism of radiotherapy sensitization drugs. Materials and Methods: The CNE-2 cell line was selec...
متن کاملRemoval of Quantifiers by Elimination of Boundary Points
We consider the problem of elimination of existential quantifiers from a Boolean CNF formula. Our approach is based on the following observation. One can get rid of dependency on a set of variables of a quantified CNF formula F by adding resolvent clauses of F eliminating boundary points. This approach is similar to the method of quantifier elimination described in [9]. The difference of the me...
متن کاملSome points on the elimination of leprosy.
During the last decade, and on a large scale since 1 987-88, the widespread use of multidrug therapy (MDT) regimens in leprosy control programmes, as recommended by WHO in 1 9825 and in 1 9886, has dramatically changed the leprosy situation.9 While in 1986 5 ·3 million leprosy cases were registered worldwide, there are now 2·3 million patients registered for treatment, of whom 1 , 1 00,000 are ...
متن کاملShape-Aware Line Generalisation With Weighted Effective Area
Few line generalisation algorithms provide explicit control over the style of generalisation that results. In this paper we introduce weighted effective area, a set of area-based metrics for cartographic line generalisation following the bottom-up approach of the Visvalingam-Whyatt algorithm. Various weight factors are used to reflect the flatness, skewness and convexity of the triangle upon wh...
متن کاملOn-line learning and generalisation in coupled perceptrons
We study supervised learning and generalisation in coupled perceptrons trained on-line using two learning scenarios. In the first scenario the teacher and the student are independent networks and both are represented by an Ashkin-Teller perceptron. In the second scenario the student and the teacher are simple perceptrons but are coupled by an Ashkin-Teller type four-neuron interaction term. Exp...
