Purpose: BRAF is frequently activated by gene fusion or point mutation in pilocytic astrocytoma, the most common pediatric brain tumor. We investigated the functional effect of constitutive BRAF activation in normal human neural stem and progenitor cells to determine its role in tumor induction in the brain. Experimental Design: The constitutively active(More)
BACKGROUND Image-guided procedures such as computed tomography (CT) guided, neuronavigator-guided and ultrasound-guided methods can assist neurosurgeons in localizing the intraparenchymal lesion of the brain. However, despite improvements in the imaging techniques, an accurate diagnosis of intrinsic lesion requires tissue sampling and histological(More)
Tubular aggregate myopathy (TAM) is a rare form of myopathy with an autosomal dominant or recessive pattern. Four rare cases of TAM are described. All patients presented with muscle aches and pains, sometimes cramps. Muscle biopsies were snap frozen and processed for routine, special, enzyme, and immunohistochemistry. Tissue was also processed for electron(More)
BACKGROUND Non-functioning pituitary adenomas (NFPA) are characterized by the lack of clinical syndrome as compared to functioning adenomas (FA) but not all functioning adenomas have clinical effects. Their exact incidence varies in different series. MATERIALS AND METHODS This study was undertaken to analyze the hormonal profile of NFPA at the(More)
The hippo pathway and its downstream mediator yes-associated protein 1 (YAP1) regulate mammalian organ size in part through modulating progenitor cell numbers. YAP1 has also been implicated as an oncogene in multiple human cancers. Currently, little is known about the expression of YAP1 either in normal human brain tissue or in central nervous system(More)
Dysembryoplastic neuroepithelial tumor (DNT) is a relatively newly described entity and is an important cause of intractable epilepsy. We report 32 cases of DNT who were operated and treated in our hospital over a period of 12 years. Immunostaining for various proliferative markers and tumor suppressor gene proteins was done to assess the proliferative(More)
Transition metal complexes of Co(II), Ni(II) and Cu(II) metal ions with general stoichiometry [M(L)X]X and [M(L)SO(4)], where M = Co(II), Ni(II) and Cu(II), L = 3,3'-thiodipropionic acid bis(4-amino-5-ethylimino-2,3-dimethyl-1-phenyl-3-pyrazoline) and X = NO(3)(-), Cl(-) and OAc(-), have been synthesized and structurally characterized by elemental analyses,(More)
Our objective was to examine the reliability of histological diagnosis achieved vis a vis the number of biopsy bits obtained along a single trajectory of the stereotactic needle. A retrospective analysis of stereotactic biopsies performed in a single tertiary care neurosciences center, during a period of 11 years, between 1995 to 2005 was done. The overall(More)
BACKGROUND Previous studies support a role for mitogen-activated protein kinase pathway signaling, and more recently Akt/mammalian target of rapamycin (mTOR), in pediatric low-grade glioma (PLGG), including pilocytic astrocytoma (PA). Here we further evaluate the role of the mTORC1/mTORC2 pathway in order to better direct pharmacologic blockade in these(More)
OBJECTIVE To analyze host genetic factors immunoglobulin G Fc receptors (FcgammaRs) and human leukocyte antigen (HLA) class II in GBS patients. METHODS FcgammaRIIA, IIIA and IIIB polymorphisms were studied in 80 each GBS patients and healthy controls by allele specific PCR. HLA class II DRbeta1 and DQbeta1 typing was performed at the two-digit level by(More)
