We have examined the regional brain distribution of [18F]GBR 13119 (18F: beta +, T1/2 = 110 min), a dopamine uptake inhibitor, in CD-1 and C57BL/6 mice. High levels of binding are observed in the striatum of both species, with striatum/cerebellum ratios of 3-4 at 60 min after injection of the radiotracer. Striatum radioactivity and striatum/cerebellum ratios are more than 50% reduced in C57BL/6...

The original proposal of the IOI Syllabus was co-authored by Tom Verhoeff1, Gyula Horváth2, Krzysztof Diks3, and Gordon Cormack4. The current maintainer of the Syllabus is Michal Forǐsek5. The Syllabus evolves thanks to input from the IOI community. The following people helped to evolve the Syllabus by sending in their feedback: Paul Ashton (NZL), Thomas Barnet-Lamb (GBR), Giorgio Casadei (ITA)...

In this study, leaf area prediction models of Dendrobium nobile, were developed through machine learning (ML) techniques including multiple linear regression (MLR), support vector (SVR), gradient boosting (GBR), and artificial neural networks (ANNs). The best model was tested using the coefficient determination (R2), mean absolute errors (MAEs), root square (RMSEs) statistically confirmed avera...

The diffuse gamma-ray background radiation (GBR) at high Galactic latitudes could be dominated by inverse Compton scattering (ICS) of cosmic ray (CR) electrons on the cosmic microwave background radiation (CBR) and on starlight (SL) in an extended CR halo of our galaxy. Assuming the locally observed CR electron spectrum beyond a few GeV, which follows from equilibrium between Fermi acceleration...

Osteosynthesis screws and titanium or resorbable pins have been recommended for fixing guided bone regeneration (GBR) membranes and stabilizing the graft. However, the removal of fixation screws or pins often requires an additional surgical procedure. This article presents a periosteal suturing technique with resorbable sutures for the fixation of grafts and membranes in GBR in single implant s...

Mass coral bleaching affected large parts of the Great Barrier Reef (GBR) in 1998 and 2002. In this study, we assessed if signatures of these major thermal stress events were recorded in the growth characteristics of massive Porites colonies. In 2005 a suite of short (<50 cm) cores were collected from apparently healthy, surviving Porites colonies, from reefs in the central GBR (18-19°S) that h...

Detecting changes to the transparency of the water column is critical for understanding the responses of marine organisms, such as corals, to light availability. Long-term patterns in water transparency determine geographical and depth distributions, while acute reductions cause short-term stress, potentially mortality and may increase the organisms’ vulnerability to other environmental stresso...

OBJECTIVE This study evaluated the effectiveness of guided bone regeneration (GBR) carried out with xenogenic bone substitute (Bio-OssTM) and collagen resorbable membrane (Bio-GideTM) to improve gingival smile (GS) in patients with excessive vertical maxillary growth (EVMG). METHODS Twelve healthy women aged between 20 and 49 years old (mean age of 26 years), with 5 mm or more of gingival exp...

This paper models the downlink Fifth Generation (5G) network that supports a flexible frame structure and shorter Round Trip Time (RTT) for Hybrid Automatic Repeat Request (HARQ).  Moreover, design of renowned Division Multiple Access (TDMA) packet scheduling algorithms is revised to allow these support in 5G. Simulation results demonstrate Proportional Fair provides comparable performance dela...

Analogs of benztropine (BZT) bind to the dopamine (DA) transporter and inhibit DA uptake but often have behavioral effects that differ from those of cocaine and other DA-uptake inhibitors. To better understand these differences, we examined the relationship between locomotor-stimulant effects of cocaine, 1-{2-[bis-(4-fluorophenyl)methoxy]ethyl}-4-(3-phenylpropyl)-piperazine (GBR 12909), and BZT...
