Goodbye, login. Hello, heart scan.

(University at Buffalo) Forget fingerprint computer identification or retinal scanning. A University at Buffalo-led team has developed a computer security system using the dimensions of your heart as your identifier.The system uses low-level Doppler radar to measure your heart, and then continually monitors your heart to make sure no one else has stepped in to run your computer. The technology will be presented next month at the 23rd MobiCom conference.

Objective To evaluate the treatment response of lutetium-177 tin colloid radiosynovectomy (177Lu-RSV) in patients with inflammatory knee joint conditions refractory to conventional treatment. Patients and methods Overall, 29 knee joints in 29 patients with chronic synovitis caused by various inflammatory knee joint diseases refractory to conventional therapy were included in this prospective study. All patients were assessed clinically for pain, tenderness, joint swelling, mobility, analgesic intake, and blood pool activity on bone scan. Different scores were assigned to all these parameters. RSV of knee joint was don...

Conclusions The PLS agreement was sensitive to the 90Y lung background correction ROI, potentially explaining a previously published controversy. The mean activity and absorbed dose agreement for the metastatic lesions was poorer than the healthy liver volumes studied here.

Conclusion The calculated normal reference range in this study was found to be less than that used in our own and many other UK institutions. The results demonstrate the importance of periodic evaluation of normal uptake values and provide support for prospective studies defining the normal reference range to be performed.

This study aims to evaluate the prognostic role of the decrease in total lesion glycolysis (TLG) assessed by fluorine-18-fluorodeoxyglucose (18F-FDG) PET-computed tomography (CT) 1 month after yttrium-90-radioembolization (90Y-RE) in patients affected by hepatocellular carcinoma (HCC) with portal vein tumour thrombosis (PVTT). Patients and methods Twenty-one patients with histologically proven poorly differentiated HCC and evidence of PVTT at the enhanced multislice CT underwent 90Y-RE. All patients underwent an 18F-FDG PET-CT scan at baseline and 1 month after the loco-regional therapy. The variation in TLG (ΔTLG...

Objectives The aim of this study was to identify the optimal timing of fluorine-18-fluoromisonidazole (18F-MISO) PET/CT imaging to assess hypoxia in patients with head and neck squamous cell carcinoma. Patients and methods Eighteen patients underwent pretreatment 18F-MISO PET/CT imaging after providing written informed consent. PET scans were acquired at 1, 3, and 5 h after injection of the radionuclide. The mean standardized uptake value (SUV) within a spherical region of interest placed on the contralateral neck musculature at the level of the largest tumor dimension was labeled as background. A value 1.5 tim...

Publication date: December 2018Source: Materials Science in Semiconductor Processing, Volume 88Author(s): Shiva Navazani, Ali Shokuhfar, Mostafa Hassanisadi, Aldo Di Carlo, Nikta ShahcheraghiAbstractUsing in situ chemical polymerization, the hybridized pre-synthesized SnO2@rGO with polyaniline (SnO2@rGO-PANI) was synthetized and applied as the methane sensor at room temperature. The enhanced response of SnO2@rGO-PANI toward 100–10,000 ppm Methane at room temperature, i.e. from 26.1% to 92.3%, illustrated its excellent potential of functional properties. As a hybrid sensor, SnO2@rGO-PANI exhibited better response to...

Kirchlechner, M.S. KennedyAbstractCu/Nb nanoscale metallic multilayers have been extensively investigated to understand how their mechanical behavior is influenced by the individual layer thickness. The general observed trend is that the yield stress of the multilayer increases with decreasing layer thickness. Important mechanical behaviors that have not been studied in-depth are the fracture of these multilayers and adhesion ener...

Authors: Ogusu S, Takahashi K, Hirakawa H, Tanaka M, Komiya K, Nakamura T, Egashira R, Kai K, Takeda Y, Kimura S, Sueoka-Aragane N Abstract A 76-year-old asymptomatic man was found to have a mass in the right lower lung field. Although the presence of a mucinous component in the majority of the tumor was shown by magnetic resonance imaging, the presence of cancer cells was suspected by contrast enhancement on computed tomography (CT) and based on the partial accumulation in the marginal regions of the tumor on fluorodeoxyglucose-positron emission tomography (FDG-PET). A transbronchial lung biopsy was non-diagnostic...

Authors: Sasaki A, Egashira H, Sugimoto H, Seki K, Tsukiyama T, Ichita C, Tokoro S, Takizawa S, Kitagawa I, Teshima S, Kako M Abstract A 69-year-old male patient presented with multiple lung nodules revealed by chest-computed tomography (CT) during a preoperative examination for an appendiceal tumor. The nodule diameters ranged from 2-10 mm without either pleural thickening or effusions. A fluorine-18-labeled fluorodeoxyglucose (18F-FDG)-positron emission tomography (PET)/CT scan showed a high FDG uptake in the appendiceal tumor, but almost normal standardized uptake values in the bilateral lung nodules. A CT-guide...
