the main attempt of this article is extension the method so that it generallywould be able to consider the classical solution of the systems and moreover,produces the optimal trajectory and control directly at the same time. there-fore we consider a control system governed by a bone marrow cancer equation.next, by extending the underlying space, the existence of the solution is con-sidered and ...

introduction: the adaptive neuro-fuzzy inference system (anfis) is a soft computing model based on neural network precision and fuzzy decision-making advantages, which can highly facilitate diagnostic modeling. in this study we used this model in breast cancer detection. methodology: a set of 1,508 records on cancerous and non-cancerous participant’s risk factors was used.  first, the risk fact...

The idea of successive mutations to trigger the appearance of a cancerous cell goes back to at least Muller (1951). The first mathematical model proposed for this phenomenon goes back to Armitage and Doll (1954). There has been a great deal of discussion on the number of successive mutations necessary to get a cancerous cell. It seems that this number depends on the organ, see Knudson (1971) an...

conclusions our results suggest that h. parva and h. oculata may be promising therapeutic candidates for the treatment of hcc, following further confirmatory in vivo experiments and clinical trials. results our results showed that h. parva methanolic extracts (250, 500, and 1000 µg/ml) and h. oculata methanolic extracts (200, 400, and 800 µg/ml) increased reactive oxygen species (ros) formation...

the reliability of gene expression profiling based technologies and methods to find transcriptional differences representative for the original samples is influenced by the quality of the extracted rna. hence, rna extraction is the first step to investigate the gene expression and its function. consequently, the quality of extracted rna is really significant. correspondingly, this research was ...

This paper presents a 2-D model to calculate the electric current densities and the biopotential differences generated due to a breast cancerous cell during the hyperpolarization of the G1/synthesis (G1/S) transition. The proposed model is based on semiconductor diffusion-drift analysis, and aims to understand the biophysics associated with growing breast cancerous cells. The effect of the dura...
