Introduction: GFAP is the major constituent of intermediate filaments in normal, reactive and neoplastic astrocytes. It serves as a marker of glial differentiation.Materials and Methods: In this study GFAP immunoreactivity was investigated in different types of brain tumors, including astrocytomas (7),...
MRI brain scan Glioma is a common name for serious brain tumours. Different types of glioma are usually diagnosed as separate diseases and have been considered to arise from different cell types in the brain. Now researchers at Uppsala University, together with American colleagues, have shown that...
Brain atrophy, also referred to as cerebral atrophy, refers to the reduction in the size of the brain. Several conditions can cause a brain to atrophy, including diseases and aging. The various types of cerebral atrophy include those classified as generalized and those classified as focal. ...
multiple intracranial tumorsWe report the case of a patient with two distinct brain tumors. A meningioma was resected surgically. Nine months later a glioblastoma appeared in the same region, but at a different site. This was not treated, because the patient died. The clinical significance and ...
Pituitary neuroendocrine tumors (PitNETs) are a frequently occurring form of intracranial brain tumor. The estimated prevalence rate of clinically significant PitNETs is approximately 1 case per 1000 individuals [1]. About 2% of cases display aggressive behavior, while up to 15% show invasion, with...
brain tumors is provided by simple diffiusion through the disrupted blood-brain barrier. The dynamics of the uptake and washout phases are not identical because there are biological processes favoring the transport of gadolinium carriers into the extravascular space.1Doses of GdDTPA larger than ...
Multiple primary brain tumors of different histological types--report of two cases. Simultaneous development of histologically different primary brain tumors aside from phacomatoses or previous irradiation is rare, and its preoperative dia... T,Tokunaga,M,... - 《Neurologia Medico Chirurgica》 被引量...
Explain the various types of cancer. What are the causes of brain tumors? Secondary tumors release angiogenic proteins. Why, then, do some of these tumors not grow bigger? Why do cancer cells divide? Why does cancer refer to the malignant growth of the body tissues?
was performed on 428 biological samples of 12 blood cell types. BA values were different in the majority of the pairwise comparisons between cell types, as well as in comparison to whole blood (p < 0.05). DNAmPhenoAge showed the largest cell type differences, up to 44.5 years and DNA...
