☆Symposium: Imaging modalities for drug-related osteonecrosis of the jaw (5), utility of bone scintigraphy and 18F-FDG PET/CT in early detection and risk assessment of medication-related osteonecrosis of the jaw (secondary publication)

Publication date: November 2019Source: Japanese Dental Science Review, Volume 55, Issue 1Author(s): Satoru Watanabe, Kenichi Nakajima, Seigo KinuyaSummaryMedication-related osteonecrosis of the jaw (MRONJ) is a significant side effect of antiresorptive and antiangiogenic drugs. Since MRONJ is intractable, early detection is the best way to limit progression. Bone scintigraphy and 18F- fluorodeoxyglucose positron-emission tomography can detect minimal and subclinical changes in bones earlier than conventional radiological modalities. A differential diagnosis including MRONJ is recommended when abnormally high uptakes are incidentally detected in the jaws of patients who have bone metastases. Quantitative analysis of uptakes, such as bone scan index of the jaw using neural network analysis and maximum standardized uptake value, could differentiate MRONJ from common dental diseases and be useful for the early detection and risk assessment of MRONJ.

Short-eared Owl at Burwell Fen, photographed mid-January One evening in late November, I was once again, hoping to catch sight of the Starling murmurations that occur over the Broad Lane balancing pond. As mentioned in a previous, issue the local Starlings and their continental counterparts will often roost in the reed bed there, last winter there were literally thousands. At the time of writing, just a few hundred are roosting, but that can change on a wind as arrivals from Europe turn up when the weather changes. Anyway, reader Alison waved as she passed the pond on her dog walk. I later heard that she’d seen a scu...

Abstract In this work, a selective silica-based molecular imprinted solid-phase microextraction (SPME) sorbent was prepared through the sol-gel process. Difenoconazole was used as a template to prepare imprinted materials on the surface of mesoporous silica. The SPME fiber followed by gas chromatography-electron capture detection was applied for the extraction and determination of difenoconazole. Fourier transform infrared spectrometry, field emission scanning electron microscopy, X-ray diffraction, and thermal gravimetry were used to characterize the imprinted SPME fiber. Two different procedures were presented t...

Oza, Abhishek Kumar, Vishvesh BadhekaAbstractIn this industrial revolution era, machining of advanced non-conducting material like quartz is difficult and costly with existing conventional machining processes. Further its high hardness, brittleness and non-conducting nature add-up to machining difficulties. Traveling Wire-electrochemical discharge machining (TW-ECDM) process has a good potential of machining of quartz material. TW-ECDM process is a hybrid and complex combination of electrochemical machining (ECM) and w...

Carbon fiber-reinforced polymer (CFRP) is one such material which is not compatible with the traditional micro-machining process due to excessive damage to the machined surface in terms of fiber breakage, delamination, fiber pull-out, etc...

In this study, we investigated the synergistic cytotoxic effect of gemcitabine (GEM) conjugated non-cytotoxic dose of silver nanoparticles (AgNP) in MDA-MB-453 human triple-negative metastatic breast cancer cells. Synthesized AgNP and electrostatic conjugates were characterized by UV-spectroscopy, dynamic light scattering (DLS), Transmission electron microscopy (TEM), Scanning electron microscopy (SEM) and energy dispersive x-ray analysis (EDAX). GEM-(non-cytotoxic AgNP) conjugated system (IC50 = 37.64 μM) showed better cytotoxic activity in MDA-MB-453 cells when compared to individual treatments of GEM (IC50 = 56.54 &m...

In this study, polypyrrole (PPy)-PEO composite films, doped with dodecylbenzene sulfonate, were electropolymerized from solutions with different concentrations of PEO. The obtained films were studied by atomic force microscopy (AFM), scanning electron microscopy (SEM), Raman, FTIR and energy dispersive X-ray spectroscopy (EDX). Electrochemical impedance spectroscopy (EIS) and modified scanning ionic conductance microscopy (mSICM) allowed the determination of electronic and ionic conductivities of the samples. Their electro-chemo-mechanical deformations (ECMD) were investigated under cyclic voltammetry. In aqueous electroly...

In this study, oriented assemblies of trace fluorine substituted calcium deficient hydroxyapatite (FHA) nanorod bundles have been synthesized via a controlled thermal process. The FHA was characterized by scanning electron microscopy, X-ray diffraction, transmission electron microscopy and crystal model. The results show that the as-prepared FHA samples are nanorod bundles with a length of about 3 μm, and a diameter of about 100 nm. After the encapsulation of model drug Doxorubicin (DOX), a sustained and controlled release profile was achieved. The special structures of the oriented assemblies of FHA nanorod b...
