Modeling the tumor behavior in the host organ as function of time and radiation dose has been a major study in the previous decades. Here the effort in estimation of cancerous and normal cell proliferation and growth in glioblastoma multiform (GBM) tumor is presented. This paper introduces a new mathematical model in the form of differential equation of tumor growth. The model contains dose del...

Abstract The effects observed under near-infrared laser irradiation of mammalian cells have been demonstrated to depend a large extent on the type source. In our experiments, we measured concentration reactive oxygen species in cell cultures different origin (rodent and human, cancerous non-cancerous) exposed radiation low-level lasers at 1265 nm. Surprisingly, narrowband occur be more pronounc...

It is aimed to evaluate the actual anti-cancerous effects of metformin on cancer cells in hypoxic condition. Non-cancerous cells (HEK293) and cancer cells (MCF-7) were cultured in both hypoxia and normoxia conditions and treated with different concentrations of metformin. The proliferation, apoptosis, and necrosis rate were assessed using MTT test and Annexin V assay. The S6K1 phosphorylation w...

BACKGROUND MicroRNA-106b (miR-106b) is thought to be an oncogenic microRNA that promotes tumor growth and metastasis. The potential predictive value of miR-106b was studied in colonic cancer patients. METHODS The expression of miR-106b was examined in 180 colonic cancer cases using in situ hybridization (ISH) technique and was evaluated semi-quantitatively by examining the staining index. The...

This paper discusses the use of Fister-Panetta model in the visualisation of cancerous growths. Cancer evolution and the associated proper medication strategy is an example of such a complex problem that requires an interdisciplinary approach in order to be properly addressed. The paper addresses some basic aspects regarding how cancer research could benefit from the cooperation between mathema...

Heparan sulfate fractions were isolated from three normal human livers and three cancerous human liver tissues, and their polyanionic properties were examined using electrophoresis, sequential partition fractionation, and chemical analyses. More than 60% of total glycosaminoglycans from normal human liver and about 30% from cancerous liver tissue were found to be heparan sulfate from their resi...

Background and study aims  With magnifying narrow-band imaging (M-NBI) of the gastric mucosa, a characteristic demarcation line (DL) is occasionally found in non-cancerous depressed lesions. This DL forms multiple convex shapes along the edge of the epithelia of surrounding mucosa. We have termed this novel finding a multiple convex DL (MCDL). In this study, we clarified the prevalence of an MC...
