Medical and Biotech [MESH] Definitions
Tandem Mass Spectrometry
A mass spectrometry technique using two (MS/MS) or more mass analyzers. With two in tandem, the precursor ions are mass-selected by a first mass analyzer, and focused into a collision region where they are then fragmented into product ions which are then characterized by a second mass analyzer. A variety of techniques are used to separate the compounds, ionize them, and introduce them to the first mass analyzer. For example, for in GC-MS/MS, GAS CHROMATOGRAPHY-MASS SPECTROMETRY is involved in separating relatively small compounds by GAS CHROMATOGRAPHY prior to injecting them into an ionization chamber for the mass selection.
An analytical method used in determining the identity of a chemical based on its mass using mass analyzers/mass spectrometers.
Rare, slow-growing, benign intraventricular tumors, often asymptomatic and discovered incidentally. The tumors are classified histologically as ependymomas and demonstrate a proliferation of subependymal fibrillary astrocytes among the ependymal tumor cells.

Spectrometry, Mass, Fast Atom Bombardment
A mass spectrometric technique that is used for the analysis of a wide range of biomolecules, such as glycoalkaloids, glycoproteins, polysaccharides, and peptides. Positive and negative fast atom bombardment spectra are recorded on a mass spectrometer fitted with an atom gun with xenon as the customary beam. The mass spectra obtained contain molecular weight recognition as well as sequence information.
Spectrometry, Mass, Secondary Ion
A mass-spectrometric technique that is used for microscopic chemical analysis. A beam of primary ions with an energy of 5-20 kiloelectronvolts (keV) bombards a small spot on the surface of the sample under ultra-high vacuum conditions. Positive and negative secondary ions sputtered from the surface are analyzed in a mass spectrometer in regards to their mass-to-charge ratio. Digital imaging can be generated from the secondary ion beams and their intensity can be measured. Ionic images can be correlated with images from light or other microscopy providing useful tools in the study of molecular and drug actions.
Chordoid glioma is a rare tumor (World Health Organization grade II) with both glial and chordoid features, often located in the suprasellar region and anterior third ventricle. It was first described...
Chordoid glioma is a rare, slowly growing tumor of the CNS, which is always located in the third ventricle of adults. Chordoid glioma has classic histological features consisting of clusters and cords...
We present a case of primary chordoid meningioma of the lung in a 21-year-old patient with Diamond-Blackfan anemia. The neoplasm was incidentally discovered as a new right upper lobe mass on admission...
The chordoid variant of meningioma is a histological subtype which carries with it a more aggressive clinical course and a propensity for recurrence. Similar to other meningioma subtypes, this lesion...
We report the case of a 28-year-old man who presented with the sole complaint of lumbago. Spinal magnetic resonance imaging (MRI) revealed a solitary, welldefined intramedullary mass at the L1-L2 leve...
This drug is being developed to treat a type of brain cancer, glioma. This study was developed to evaluate the safety, time to disease progression and survival rates after treatment.
Phase IIa Safety and Light Dose-Escalation Study in Patients With Primary or Recurrent/High-Grade Glioma Using the Litx™ System to Confirm the Zone of Tumor Destruction During the Intraoperative Treatment of Glioma
The pupose of this study is to demonstrate the safety of the Litx™ therapy and confirm the zone of tumor destruction with escalated light doses following intraoperative treatment of prim...
The purpose of this trial is to determine the effects (good and bad) temozolomide has on patients with low-grade glioma. It will also determine whether temozolomide is effective in preven...
The purpose of this study is to evaluate the effectiveness and safety of AMG 102 for the treatment of Advanced Malignant Glioma.
A single-arm, one-stage phase II trial of RAD001 will be undertaken. Sixty patients will be enrolled. The target population will be patients with a diagnosis of low-grade glioma who expe...
