BACKGROUND The relationship between reduced glucose metabolism in positron emission tomography with fludeoxyglucose F 18 ([(18)F]FDG-PET) and hippocampal damage (HD) in patients with temporal lobe epilepsy is still unclear. OBJECTIVE To determine whether the presence and severity of HD verified by quantitative magnetic resonance imaging (QMRI) and histopathological analysis affect the degree ...

The effect of nanoclay concentration on the molecular orientation and drawability of poly(ethylene terephthalate) PET was examined using thermal and vibrational spectroscopic analysis. Although drawability at 83 C in hot air increased by the addition of nanoclay, the maximum draw ratio was independent of nanoclay concentration. The average molecular orientation of the PET chain was found to mim...

UNLABELLED Olfactory dysfunction is an early feature of Alzheimer disease. This study used multimodal imaging of PET and (18)F-FDG combined with diffusion tensor imaging (DTI) to investigate the association of fiber tract integrity in the olfactory tract with cortical glucose metabolism in subjects with mild cognitive impairment (MCI) and normal controls. We hypothesized that MCI subjects would...

Oil palm empty fruit bunches (OPEFB) fiber is a natural that possesses many advantages, such as biodegradability, eco-friendly, and renewable nature. The effect of the OPEFB loading reinforced fire retardant epoxy composites on flammability tensile properties polymer biocomposites were investigated. tests carried out with four parameters, which specimen A (constant), B (20% fiber), C (35% D (50...

A new magnetic resonance imaging (MRI)-compatible positron emission tomography (PET) detector design is being developed that uses electro-optical coupling to bring the amplitude and arrival time information of high-speed PET detector scintillation pulses out of an MRI system. The electro-optical coupling technology consists of a magnetically insensitive photodetector output signal connected to ...

objective(s): the ability to measure cellular proliferation non-invasively in renal cell carcinoma may allow prediction of tumour aggressiveness and response to therapy. the aim of this study was to evaluate the uptake of 18ffluorothymidine (flt) pet in renal cell carcinoma (rcc), and to compare this to 18f-fluorodeoxyglucose (fdg), and to an immunohistochemical measure of cellular proliferatio...

Surface modification enables fiber lubrication and processing but little is known about the extent and dynamics of adsorption of typical adsorbates applied for such purposes, which often includes water-soluble block nonionic amphiphilic polymers. In this work we used quartz crystal microgravimetry (QCM) to investigate the adsorption on poly(ethylene terephthalate) (PET) of polyalkyl glycol ethe...

This paper provides experimental results to investigate the mechanical properties of sustainable strain-hardening cement composite (2SHCC) for infrastructures after freeze-thaw actions. To improve the sustainability of SHCC materials in this study, high energy-consumptive components-silica sand, cement, and polyvinyl alcohol (PVA) fibers-in the conventional SHCC materials are partially replaced...

PURPOSE We report three cases of dysembryoplastic neuroepithelial tumor (DNT) with intractable epilepsy which were successfully treated with surgery. METHODS In all cases, technology beyond the routine workup was critical to success. Preoperative magnetic resonance imaging, (18)F-fluorodeoxyglucose positron emission tomography (PET), (11)C-methionine-PET, interictal electroencephalography, an...
