ConclusionsPBS gives good target coverage and local control while providing reductions in radiation dose to OARs for individuals who receive RT for HL compared with advanced photon RT. Our findings highlight groups of patients who would be expected to gain more dosimetric benefit from PBS. These findings facilitate the selection of patients who should be considered a priority for PT.

Publication date: Available online 18 March 2019Source: Tribology InternationalAuthor(s): Jitendra Narayan Panda, Jayashree Bijwe, Raj K. PandeyAbstractThe paper reports on the comparative potential of nano-particles and micro-particles of mica in glass fiber reinforced Polyaryletherketone (PAEK) composite containing graphite (10 wt%). Very high PVlimit value (>100 MPa-m/s), very low specific wear rate (K0) (2–∼8 × 10−16 m3/Nm) along with very low friction coefficient (μ) (0.04–0.08), were exhibited by the composites. The PVlimit values of a nano-composite (NC) and micro-composit...

Publication date: Available online 18 March 2019Source: Materials LettersAuthor(s): Kyung Ho Kim, Sena Motoyama, Mashashi Ohara, Yoshio Abe, Midori Kawamura, Takayuki KibaAbstractCobalt hydroxide (Co(OH)2) nanostructures were prepared on fluorine-doped tin oxide (FTO) substrates via an inexpensive and simple wet-chemical method. At a growth temperature of 60 °C, heterogeneous nucleation caused the nanowire-net structured Co(OH)2 to form a compact bottom layer on the surface of FTO substrate, and homogeneous nucleation resulted in the growth of a porous nanowire-net layer in the solution as the top layer. At 90 °C, ...

In this study, fifteen healthy participants were scanned three times in a strictly controlled in-laboratory study while at rest and during performing a simple and reliable psychomotor vigilance test (PVT). The reliability of absolute CBF and task-induced CBF changes was evaluated using the intraclass correlation coefficient (ICC) and compared to that of task performance. Absolute CBF showed excellent test-retest reliability across the three scans for both resting and PVT scans. The reliability of regional absolute CBF was comparable to that of behavioral measures of PVT performance, and was slightly higher during PVT scans...

Publication date: Available online 18 March 2019Source: Journal of Food EngineeringAuthor(s): Jang Ho Lee, Dong Jae Won, Hyun Woo Kim, Hyun Jin ParkAbstractThe effect of the particle sizes (307, 259, 172, and 50 μm) on rheological properties and printing performance for a food-ink dispersion system that 20% (w/w) of spinach powder was incorporated in 10% (w/w) xanthan gum mixture was investigated. Scanning electron microscopy images demonstrated that the larger particle size (307 μm and 259 μm) possess a skeletal-like and cellular structure, and are more porous than the smaller particle size (up to 172 μm). The...

Abstract A non-enzymatic electrochemical sensor-NiCo2S4/GCE was constructed for sensitive and selective detection of hydrazine (N2H4), which was designed based on porous nanostructure and synthesized through a facile hydrothermal method. The nanocomposite has been characterized using a series of characterizations such as X-ray powder diffraction (XRD), scanning electron microscopic (SEM), transmission electron microscopy (TEM), showing the porous NiCo2S4 sphere was made of interconnected nanoparticles with porous structure. Electrochemical measurements revealed that the porous NiCo2S4 sphere based sensor exhibited...

Abstract An extremely sensitive and highly simple aptasensor was fabricated for quantitation of amyloid beta (Aβ) by electrochemical transduction of a fern leaves-like gold nanostructure. The gold nanostructure was synthesized by electrodeposition using polyethylene glycol 6000 as a shape-directing agent, and characterized electrochemically and by field emission scanning electron microscopy. A specific RNA aptamer was immobilized on the fern leaves-like gold nanostructure, and binding with Aβ was detected by the ferro/ferricyanide redox marker. The designed aptasensor was able to detect Aβ in a line...

cute; Abstract Consumer electronic technologies offer practical performances to develop compact biosensing systems intended for the point-of-care testing of DNA biomarkers. Herein a discrimination method for detecting single nucleotide polymorphisms, based on isothermal amplification and on-chip hybridisation, was developed and integrated into user-friendly optical devices: e.g., USB digital microscope, flatbed scanner, smartphone and DVD drive. In order to adequately identify a single base change, loop-mediated isothermal amplification (LAMP) was employed, with high yields (8 orders) within 45 min. Subsequently...

Abstract Laser-induced fluorescence (LIF) rotary scanners have been successfully used for multiplexed capillary detection. However, these scanners have a limitation that the capillaries have to be assembled in a circular format, which can be inconvenient for certain applications. A linear LIF scanner works well for flat parallel capillary arrays, but motor accelerations/decelerations (for direction changes) and scanning head vibrations introduce high instrumental noises. The number of capillaries that can be scanned by a linear scanner is limited because of the above constraints. We have constructed a cam-based sc...
