The association of p53 abnormalities with the prognosis of patients with non-small cell lung carcinoma (NSCLC) has been extensively investigated to date, however, this association is still controversial. Therefore, we investigated the prognostic significance of p53 mutations through exons 2 to 11 and p53 protein expression in 103 cases of stage I NSCLC. p53(More)
To date, the characteristics of p53 gene mutations in lung cancer have been extensively investigated. However, current estimates of p53 alterations are inaccurate, since most investigators have limited their analyses to exons 5 to 8 of the p53 gene. We examined 52 lung carcinoma cell lines and 106 primary non-small cell lung carcinomas (NSCLC) for mutations(More)
A chemical robot capable of performing enzymatic reactions and extraction processes of DNA has been developed. The basic functions of this robot include handling of plastic tubes with caps, micropipetting, mixing, microcentrifuging and incubating. As a result, almost all of the pre-electrophoresis steps can be carried out. In addition, because these(More)
Single-stranded conformational polymorphism (SSCP) analysis is useful for mutation detection and polymorphism identification. To realize high-throughput SSCP analysis using a high-intensity electric field, the gel temperature must be well-controlled. We have developed an electrophoretic system having a pair of glass plates with an efficient(More)
This paper reports that in parallel Monte-Carlo simulations of the 2D Ising-Model, commonly used pseudo-random number generators (PRNG) lead to manifestly erroneous results. When parallel random number sequences for a parallel simulation are generated by a same PRNG with diffrent initial seeds, the sequences can be strongly correlated with each other if the(More)
