gamma knife is a new noninvasive method for treatment of patient with brain tumors. ‎another name of this procedure is steriotatic radiosurgery.‎‏ ‏this computerized advanced ‎technique was implicated by a team including neurosurgeon, neuroradialogist, oncologist, and ‎a nurse. this method is used for treatment of certain brain tumors and lesions. the benefits are ‎low risk of postoperative com...

Tumors of the Central nervous System (CNS) are a spectrum neoplasms that range from benign lesions to highly malignant and aggressive lesions. Despite multimodal treatment approaches, morbidity mortality high with dismal survival outcomes in these tumors. Moreover, non-specificity conventional treatments substantiates rationale for precise therapeutic strategies selectively target infiltrating ...

despite many advances in the field of cancer treatment, intra-cranial tumor cases still have a poor prognosis. this research has been carried out in order to describe age and sex distributions and histopathological characteristics and site of intra-cranial tumors. we studied 425 patients with intra-cranial tumor whose samples were examined in pathology center of imam khomeini hospital from 1991...

The BK virus a member of the Polyomaviruses family was first isolated from the urine of the kidney recipient. Infection with this virus and infection usually occurs in childhood (5-9 years) but most of the time (90%) of sera are positive and without symptoms. Polyomaviruses including the BK virus have also been suggested to be a contributing factor to some cancers in humans such as brain tumors...

Abstract Brain tumors are a large and heterogeneous group of neoplasms that affect the central nervous system include some deadliest cancers. Almost all conventional new treatments fail to hinder tumoral growth most malignant brain tumors. This is due multiple factors, such as intra-tumor heterogeneity, microenvironmental properties human brain, lack reliable models test therapies. Therefore, c...

A brain tumor is the cause of abnormal growth cells in brain. Magnetic resonance imaging (MRI) most practical method for detecting tumors. Through these MRIs, doctors analyze and identify tissue can confirm whether affected by a or not. Today, with emergence artificial intelligence techniques, detection tumors done applying techniques algorithms machine learning deep learning. The advantages ap...

A tumor is carried on by rapid and uncontrolled cell growth in the brain. If it not treated initial phases, could prove fatal. Despite numerous significant efforts encouraging outcomes, accurate segmentation classification continue to be a challenge. Detection of brain tumors significantly complicated distinctions position, structure, proportions. The main disinterest this study stays offer inv...

Introduction: Glioblastoma multiforme (GBM) is an aggressive case of primary brain cancer which remains among the most fatal tumors worldwide. Although, some in vitro and in vivo models have been developed for a better understanding of GBM behavior; a natural model of GBM would improve the efficiency of experimental models to human GBM tumors. We aimed at the present study to examine the surviv...
