A brain tumor is a problem that threatens life and impedes the normal working of human body. The needs to be identified early for proper diagnosis effective treatment planning. Tumor segmentation from an MRI image one most focused areas medical community, provided non-invasive imaging. Brain involves distinguishing abnormal tissue tissue. This paper presents systematic literature review strateg...
normal pressure hydrocephalus (nph) is characterized by gait apraxia, urinary incontinence, and dementia. mixed connective tissue disease (mctd) is an autoimmune connective tissue disease that has never been reported to cause nph. our patient was a 67-year man with a one-year history of gradual worsening gait and balance, urinary urgency with urge incontinence and decreased short-term memory. p...
Introduction The Gamma Knife system is designed solely for non-invasive treatment of brain disorders, and it benefits from stereotactic surgical techniques. Dose calculations required in the system are performed by GammaPlan code; in this code, brain tissue is considered uniform. In the present study, we evaluated the effect of Gamma Knife system on the obtained dose through simulating a real ...
Background & Aim: Organophosphates (OPs) are capable to produce free radicals and induce disturbance in body antioxidant system. Diazinon is one of the most widely used OPs in agriculture. The aim of this study was to investigate the effects of diazinon on oxidant-antioxidant system in rat's brain tissue.Material and Method: In this experimental study, male Wistar rats were randomly divided...
Introduction: It has been shown that mobile radiations (MRs) have detrimental effects on brain histoarchitecture and vitamin E as a powerful antioxidant can exhibit neuroprotective effects. This study was carried out to evaluate the protective effects of vitamin E against MRs-induced histological changes in rat brain. Methods: Adult female Wistar rats were randomly categorized into 4 groups (n...
objective(s): recently, applications of mno2 nanoparticles and microparticles in industry, pharmacology, and medicine have considerably expanded. mn distribution and clearance from brain and spinal cord tissue compared with muscle tissue of rats after single subcutaneous injection of nanoparticles and microparticle of mno2. pain sensory threshold of rat was evaluated as neurologic consequence...
