An efficient approach for reference deconvolution of two-dimensional spectra aiming at the correction of static field inhomogeneity was established. In comparison to known techniques, a great improvement was achieved using the cross-section along the diagonal of the reference peak instead of its full 2D line shape. The method is termed pseudo-2D diagonal deconvolution. The approach developed allows suppressing the two-dimensional peaks tilting caused by the magnetic field inhomogeneity, while keeping the signal-to-noise ratio constant...

Inappropriate social behaviour is an early symptom of frontotemporal lobar degeneration (FTLD) in both behavioural variant frontotemporal dementia (bvFTD) and semantic dementia (SD) subtypes. Knowledge of social behaviour is essential for appropriate social conduct. The superior anterior temporal lobe (ATL) has been identified as one key neural component for the conceptual knowledge of social behaviour, but it is unknown whether this is dissociable from knowledge of the consequences of social behaviour. Here, we used a newly-developed test of knowledge about long-term and short-term consequences of social behaviour to investigate its impairment in patients with FTLD relative to a previously-developed test of social conceptual knowledge...

Anisakids are parasitic nematodes responsible for a zoonosis that occurs following the ingestion of fish and fish products infected with larvae belonging to the genera Anisakis and Pseudoterranova. Rarely Contracaecum is found in association with gastric/intestinal illness, while Hysterothylacium is commonly considered not pathogenic. Although Real Time PCR assays have been recently used with the aim to detect and quantify these parasites in food products, methods applied did not undergo through extensive validation process, a feature highly desirable or mandatory in the case of testing laboratories accredited for the ISO EN 17025:2005...

Xinhui Wang, Arman Rahmim, Jing Tang
PURPOSE: Myocardial perfusion (MP) PET imaging is a powerful tool in risk assess-assessment and stratification of patients with coronary artery disease. Involuntary organmotion degrades cardiac PET image resolution while respiratory and/or cardiac gating to freeze the motion leads to noisier reconstructed images due to reduced counts in the gated frames. In this work, we propose an MRI assisted dual motion correction method to compensate for respiratory and cardiac motion in MP PET data and study the impact of dual motion correction on MP defect detection using systematically designed experiments...

We developed a mathematical model of oxidative phosphorylation (OXPHOS) that allows for a precise description of mitochondrial function with respect to the respiratory flux and the ATP production. The model reproduced flux-force relationships under various experimental conditions (state 3 and 4, uncoupling, shortage of respiratory substrate) as well as time courses, exhibiting correct P/O ratios. The model was able to reproduce experimental threshold curves for perturbations of the respiratory chain complexes, the F1 F0 -ATP synthase, the ADP/ATP carrier, the phosphate/OH carrier, and the proton leak...

Background In acute myeloid leukemia controversy exists about the role of immunophenotyping of the blasts at diagnosis as a potential prognostic factor. Methods We retrospectively analyzed immunophenotypic marker expression on blasts in relation to genetic aberrancies and survival data of 684 patients. All patients were included in different studies from the HOVON/SAKK Consortium. Results Markers CD2, CD7, CD11b, CD19, CD22 and CD56 all appeared to be associated with one or more established prognostic genetic aberrancies...

Because no effective methods for preventing or screening for ovarian cancer exist, symptom recognition is integral to its early detection. The Centers for Disease Control and Prevention's Inside Knowledge: Get the Facts about Gynecologic Cancer campaign was developed to raise awareness and educate women and providers about risk factors, symptoms, recommended screening, and prevention strategies for the five main gynecologic cancers, including ovarian cancer. Inside Knowledge campaign materials were utilized by CDC's National Comprehensive Cancer Control Program grantees to educate women and providers about gynecologic cancer from 2014 to 2015...

BACKGROUND: This study aimed to investigate, by means of finite element analysis, the effect of a drill hole at the end of a horizontal osteotomy to reduce the risk of lateral cortex fracture while performing an opening wedge high tibial osteotomy (OWHTO). The question was whether drilling a hole relieves stress and increases the maximum correction angle without fracture of the lateral cortex depending on the ductility of the cortical bone. METHODS: Two different types of osteotomy cuts were considered; one with a drill hole (diameter 5 mm) and the other without the hole...

PURPOSE: Production and characterization of a chimeric fusion protein (GMZ2'.10C) which combines epitopes of key malaria parasite antigens: glutamate-rich protein (GLURP), merozoite surface protein 3 (MSP3), and the highly disulphide bonded Pfs48/45 (10C). GMZ2'.10C is a potential candidate for a multi-stage malaria vaccine that targets both transmission and asexual life-cycle stages of the parasite. METHODS: GMZ2'.10C was produced in Lactococcus lactis and purified using either an immunoaffinity purification (IP) or a conventional purification (CP) method...

A fast, easy, and cheap method for the simultaneous determination and quantification of aflatoxins (B1, B2, G1, G2), T-2 and HT-2 toxins, and fumonisins (B1, B2) in cereal-derived products was developed. This method involved a quick, easy, cheap, effective, rugged, and safe (QuEChERS) extraction coupled with liquid chromatography-tandem mass spectrometry. The method validation was performed by analyzing samples spiked at four levels, and the recoveries ranged from 83.6 to 102.9%, whereas the maximum values of repeatability and within-laboratory reproducibility were 14...

Raw materials need to be of a certain quality with respect to physical and chemical composition. They also need to have no contaminants in the form of particles because these could get into the product or indicate the raw materials are not pure enough to make a good quality product. When particles are found, it is important to identify their chemical and elemental composition to correct any process errors that can cause them and to have acceptable quality of the final product. Sources of materials can be the environment, process equipment and processing, and packaging...

Haemophilia B, a congenital haemorrhagic disease caused by mutations in coagulation factor IX gene (F9), is considered an appropriate target for genome editing technology. Here, we describe treatment strategies for haemophilia B mice using the clustered regularly interspaced short palindromic repeat (CRISPR)/Cas9 system. Administration of adeno-associated virus (AAV) 8 vector harbouring Staphylococcus aureus Cas9 (SaCas9) and single guide RNA (sgRNA) to wild-type adult mice induced a double-strand break (DSB) at the target site of F9 in hepatocytes, sufficiently developing haemophilia B...

A crystal superlattice structure featuring nonlinear layers with alternating orthogonal optic axes interleaved with orthogonal poling directions, is shown to generate high-quality hyperentangled photon pairs via orthogonal quasi-phase-matched spontaneous parametric downconversion. We demonstrate that orthogonal quasi-phase matching (QPM) processes in a single nonlinear domain structure correct phase and group-velocity mismatches concurrently. Compared with the conventional two-orthogonal-crystals source and the double-nonlinearity single-crystal source, the orthogonal QPM superlattice is shown to suppress the spatial and temporal distinguishability of the generated photon pairs by several orders of magnitude, depending on the number of layers...

In three-dimensional positron emission tomography (PET)/computed tomography (CT) imaging of the brain with (15)O-gas inhalation, high radioactivity in the face mask creates cold artifacts and affects the quantitative accuracy when scatters is corrected by conventional methods (e.g., single-scatter simulation [SSS] with tail-fitting scaling [TFS-SSS]). Here we examined the validity of a newly developed scatter correction method that combines SSS with a scaling factor calculated by Monte Carlo simulation (MCS-SSS)...
