Malignant peripheral nerve sheath tumors (MPNSTs) are rare neuroectodermal tumors resulting from the malignant transformation of benign plexiform neurofibromas. The sporadic form of these tumors is rare than familial variants (seen in neurofibromatosis Type 1) and making the diagnosis difficult. We

The main aim of this research was to demonstrate that the cortical and subcortical grey matter hypometabolism as revealed by fluorine-18 fluorodesoxyglucose-positron emission tomography ((18)F-FDG-PET) imaging in brain tumors is related to associated edema as demonstrated by magnetic resonance

The use of fluorine compounds in various areas of medicine, particularly in dentistry, as well as in agriculture and industry became very popular in the second half of the 20th century. Fluorine owed this widespread acceptance to observations that its compounds stimulate ossification processes and

BACKGROUND
Properly prepared freeze-dried bone has been used with impunity by orthopedic surgeons since 1992 without a single report of disease transmission. The aim of this study was to evaluate freeze-dried cortical allograft bone for nasal dorsal augmentation.
METHODS
Freeze-dried human cortical

The production of hydrofluoric acid (HF) and its use have increased remarkably due to the rapid development of the electronic and petrochemical industries. HF has a highly corrosive and penetrating action when it comes in contact with organic material, including body tissue. When burns are caused by

Substrate-mimetic inhibitors of sPLA2 with submicromolar in vitro potency were discovered by use of a novel dual substrate screening strategy. In vivo evaluation of selected inhibitors in the rat carrageenan paw edema model of inflammation, however, indicated that in vitro potency was not a good

OBJECTIVE
Positron emission tomography (PET) with fluorine-18 fluorodeoxyglucose (F-18 FDG) is used for the noninvasive monitoring and grading of primary brain tumors. Here the FDG uptake is positively correlated with the malignant extent of the lesion and thereby negatively correlated with patient

Metastatic brain lesions generally demonstrate hypermetabolic foci on fluorine-18 fluorodeoxyglucose (FDG) positron emission tomography (PET) images. A large area of photopenia of the brain on FDG-PET is most likely consistent with a benign etiology. The author reports 2 cases of cerebral metastases
