Background: Block-sequential regularized expectation maximization (BSREM), commercially Q. Clear (GE Healthcare, Milwaukee, WI, USA), is a reconstruction algorithm that allows for a fully convergent iterative reconstruction leading to higher image contrast compared to conventional reconstruction algorithms, while also limiting noise. The noise penalization factor β controls the trade-off between n
Background: The optimal surgical excision margins are uncertain for patients with thick (>2 mm) localised cutaneous melanomas. In our previous report of this multicentre, randomised controlled trial, with a median follow-up of 6·7 years, we showed that a narrow excision margin (2 cm vs 4 cm) did not affect melanoma-specific nor overall survival. Here, we present extended follow-up of this cohort.
Expression of mRNAs for neuropeptide Y (NPY) and its receptor subtypes Y1 (Y1-R), Y2 (Y2-R) and Y5 (Y5-R) was studied in adult rat brain using in situ hybridization after 40 rapidly recurring seizures induced with 5-min interval by hippocampal kindling stimulations. At 2-4 h post-seizure, NPY mRNA levels were markedly elevated in dentate granule cells, CA1 and CA3 pyramidal layers, amygdala and pi
Cellular localization and tissue levels of BDNF protein were studied using immunocytochemistry and enzyme immunoassay, respectively, in the cortex and striatum at different reperfusion times (0-24 h) after 2 h of unilateral middle cerebral artery occlusion (MCAO) in rats. The distribution of neuronal injury was analyzed in NeuN-, cresyl violet-, and Fluoro-Jade-stained sections. At 2 h postischemi
Background: For locally advanced Siewert type II and III tumors we have performed total gastrectomy including resection of the distal 2/3 of the esophagus, through separate abdominal and right chest incisions (THX-ABD). The procedure involves wide lymphadenectomy in the abdomen/chest and a Roux-en-Y jejunostomy to the level of the azygos vein or above. The aim of the study was to investigate short
After the disintegration of the Soviet Union, the national identities of the Eastern and Central European states are finding themselves in a process of transformation and the results are having an impact on international relations in the region. National and foreign political identities of states are constituted by means of everyday discursive practices, not least in the media. In the present stud
A novel optical design for a flexible SAXS beamline at a modern synchrotron has been implemented for the CoSAXS beamline at the 3GeV ring at the MAX TV Laboratory. The performance of the beamline has been simulated through combined ray tracing and wave propagation with the code xrt taking into account the low emittance and highly coherent beam of MAX TV and the short inter-optics distances of the
Background: Health-related illnesses such as obesity and diabetes continue to increase, particularly in groups of low socioeconomic status. The increasing cost of nutritious food has been suggested as an explanation. Objective: To construct a price index describing the cost of a diet adhering to nutritional recommendations for a rational and knowledgeable consumer and, furthermore, to investigate
Satellite remote sensing, with its unique synoptic coverage capabilities, can provide accurate and immediately valuable information on fire analysis and post-fire assessment, including estimation of burnt areas. In this study the potential for burnt area mapping of the combined use of Artificial Neural Network (ANN) and Spectral Angle Mapper (SAM) classifiers with Landsat TM satellite imagery was
Objectives To use the estimates from the Global Burden of Disease Study 2016 to describe patterns of suicide mortality globally, regionally, and for 195 countries and territories by age, sex, and Socio-demographic index, and to describe temporal trends between 1990 and 2016. Design Systematic analysis. Main outcome measures Crude and age standardised rates from suicide mortality and years of life
Ecosystem services inherently involve people, whose values help define the benefits of nature's services. It is thus important for researchers to involve stakeholders in ecosystem services research. However, a simple and practicable framework to guide such engagement, and in particular to help researchers anticipate and consider key issues and challenges, has not been well explored. Here, we use e
Surface waters can contain a diverse range of organic pollutants, including pesticides, pharmaceuticals and industrial compounds. While bioassays have been used for water quality monitoring, there is limited knowledge regarding the effects of individual micropollutants and their relationship to the overall mixture effect in water samples. In this study, a battery of in vitro bioassays based on hum
Background: The gracilis tendon is commonly used as an autograft to reconstruct torn tendons or ligaments in many parts of the body. Little is known about the subjective and functional outcome after gracilis tendon harvest. The aim of this study was to evaluate the outcome of the donor leg in patients undergoing such surgery. Methods: Patients with chronic acromioclavicular joint dislocations unde
A search for Higgs boson pair production in the bb¯ WW * decay mode is performed in the bb¯ ℓνqq final state using 36.1 fb −1 of proton-proton collision data at a centre-of-mass energy of 13 TeV recorded with the ATLAS detector at the Large Hadron Collider. No evidence of events beyond the background expectation is found. Upper limits on the non-resonant pp → HH production cross section of 10 pb a
What do we need to know about our students to better provide for more equitable outcomes? Who will succeed depends on many factors, and student personality traits constitute one factor that has received less attention in the engagement and teaching literature. The aim of the present study is to add to discussions on teaching in higher education by exploring how students differ on personality trait
We present 77 new granite whole-rock analyses from the Qattar and Gharib areas, Eastern Desert, Egypt. Both areas include a “normal” granite and either a hypersolvus (Gharib) or an almost plagioclase-free granite (Qattar) enriched in fluorite. According to earlier results, F influences element distribution in granitic melts forming complexe
