Glioblastoma is a destructive form of brain tumor that kills most patients within two years of diagnosis.Treatments for glioblastoma include the usual options of surgery, radiation therapy and chemotherapy, but there is no effective treatment. The tumors are capable of spreading tendrils out into the brain and it can grow back in a matter of months after being removed. The cancer stem cell...

Many studies have been focused on cytogenetic and molecular genetic defects in brain tumors; therefore the role of ATM as a tumor suppressor gene in these tumors is poorly considered. In this study mutation analysis of exon 19 and 39 of ATM gene and P53 accumulation were investigated by PCR-SSCP, sequencing, and flow cytometry . Four polymorphisms including D1853N, IVS 38-8 T?C, F858L, P872T we...

Abstract Background: Brain tumors are fatal malignancies which are frequently associated with psychiatric and behavioural manifestation that should be noticed. Studies suggest that the primary psychiatric dysfunctions are associated with brain tumors in 47-94 % of cases. Case report: A 26-year single woman with neuropsychic symptoms was under the drug therapy with antipsychotic, as well as sed...

The Computer associated-learning is one of the most significant achievements in field medical imaging. Generally, we use different technologies like computer tomography (CT scan) to diagnose disease or injury; lungs, liver, brain, etc. For this research, have used MRI image datasets for identification Brain tumor classification and non-tumor classification. Tumors are generally abnormal growth;...

this report describes the case of a 56 year-old man with a history of diplopia. his brain imaging showed multiple lesions with a metastatic appearance, however all investigations to determine the primary source of malignancy were negative. the patient underwent a brain biopsy, which was positive for anaplastic astrocytoma, a rare tumor that should be considered in the differential diagnosis of ...

Cells grow and then need a very neat method to create new cells that work properly to maintain the health of the body. When the ability to control the growth of the cells is lost, they are unconsidered and often divided without order. Exemplified cells form a tissue mass called the tumor. In fact, brain tumors are abnormal and uncontrolled cell proliferations. Segmentation methods are used in b...
