T -FLAIR imaging during continuous head motion: Combining PROPELLER with an intelligent marker.

Purpose: The purpose of this work is to describe a T -weighted fluid-attenuated inversion recovery (FLAIR) sequence that is able to produce sharp magnetic resonance images even if the subject is moving their head throughout the acquisition.

Methods: The robustness to motion artifacts and retrospective motion correction capabilities of the PROPELLER (periodically rotated overlapping parallel lines with enhanced reconstruction) trajectory were combined with prospective motion correction. The prospective correction was done using an intelligent marker attached to the subject.

A comparative study of diploid versus triploid Atlantic salmon (Salmo salar L.). The effects of rearing temperatures (5, 10 and 15°C) on raw material characteristics and storage quality.

Several major market operators argue that the current level of knowledge about quality is too scant to justify a switch to a large-scale production of triploid salmon. The aim of the present study was, therefore, to elucidate how rearing conditions (5, 10 and 15°C) affect the flesh quality of triploid Atlantic salmon (Salmo salar L., 1.

Aim: To examine exposure to thoracic aerosol among cement production workers during a 4-year follow-up period.

Methods: Personal shift measurements of thoracic aerosol were conducted among the cement production workers within seven job types, 22 plants, and eight European countries (including Turkey) in 2007, 2009, and 2011.

Enteropathic arthritis in Brazil: data from the Brazilian Registry of Spondyloarthritis.

Unlabelled: Inflammatory bowel diseases (Crohn's disease and ulcerative rectocolitis) have extraintestinal manifestations 25% of the patients, with the most common one being the enteropathic arthritis.

Methods: Prospective, observational, multicenter study with patients from 29 reference centers participating in the Brazilian Registry of Spondyloarthritis (RBE), which incorporates the RESPONDIA (Ibero-American Registry of Spondyloarthritis) group. Demographic and clinical data were collected from 1472 patients and standardized questionnaires for the assessment of axial mobility, quality of life, enthesitic involvement, disease activity and functional capacity were applied.

Diffusion weighted vertical gradient and spin echo.

In this work, diffusion weighting and parallel imaging is combined with a vertical gradient and spin echo data readout. This sequence was implemented and evaluated on healthy volunteers using a 1.5 and a 3 T whole-body MR system.

Evaluation of the capillaroscopy using endothelin-1 as a marker of endothelial activation in microvascular injury and cutaneous ulcerations.

Objectives: To evaluate the presence of ET-1 in patients with scleroderma and its correlation with the level of disease activity; to verify if the levels of endothelin are associated with the clinical profile and autoantibodies of scleroderma, and even if there is an association with microvascular injury detected by nailfold capillaroscopy.

Methods: A total of 74 patients, 37 patients with scleroderma, the remaining being controls, were subjected to measurement of ET-1 by ELISA. Patients with scleroderma were evaluated through a questionnaire about characteristics of the disease and determination of autoantibodies.

Real-time optical motion correction for diffusion tensor imaging.

Head motion is a fundamental problem in brain MRI. The problem is further compounded in diffusion tensor imaging because of long acquisition times, and the sensitivity of the tensor computation to even small misregistration. To combat motion artifacts in diffusion tensor imaging, a novel real-time prospective motion correction method was introduced using an in-bore monovision system.

Comparison of reconstruction accuracy and efficiency among autocalibrating data-driven parallel imaging methods.

The class of autocalibrating "data-driven" parallel imaging (PI) methods has gained attention in recent years due to its ability to achieve high quality reconstructions even under challenging imaging conditions. The aim of this work was to perform a formal comparative study of various data-driven reconstruction techniques to evaluate their relative merits for certain imaging applications. A total of five different reconstruction methods are presented within a consistent theoretical framework and experimentally compared in terms of the specific measures of reconstruction accuracy and efficiency using one-dimensional (1D)-accelerated Cartesian datasets.

Diffusion tensor imaging on teenagers, born at term with moderate hypoxic-ischemic encephalopathy.

Hypoxic-ischemic encephalopathy (HIE) is graded with three levels of severity-mild, moderate and severe. The outcome of individuals with mild and severe grades can be reliably predicted from this scheme. Individuals with moderate degree are divided in outcome between those who suffer major neurologic problems (e.

Epidural steroids for low back pain syndromes.

Background And Objectives: Low back pain syndromes are major causes of morbidity and disability. Their therapeutic management is often based on conservative measures, such as rest, analgesia, physical therapy, and even surgical and rehabilitation procedures. This study aimed at describing the use of epidural steroids to treat low back pain syndromes.

How to correct susceptibility distortions in spin-echo echo-planar images: application to diffusion tensor imaging.

Diffusion tensor imaging is often performed by acquiring a series of diffusion-weighted spin-echo echo-planar images with different direction diffusion gradients. A problem of echo-planar images is the geometrical distortions that obtain near junctions between tissues of differing magnetic susceptibility. This results in distorted diffusion-tensor maps.

Development of an antibiotic resistance monitoring system in Hungary.

Because of the rapid development and spread of antimicrobial resistance it is important that a system be established to monitor antimicrobial resistance in pathogenic zoonotic and commensal bacteria of animal origin. Susceptibility testing of bacteria from carcasses and different samples of animal origin has been carried out in veterinary institutes for a long time but by an inconsistent methodology. The disc diffusion method proposed by the National Committee for Clinical Laboratory Standards (NCCLS) was introduced in all institutes in 1997.

Decreased infectivity in Borrelia burgdorferi strain B31 is associated with loss of linear plasmid 25 or 28-1.

Lack of DNA-strand breaks in rat testicular cells after in vivo treatment with sodium fluoride.

Oral administration of up to 84 mg/kg of NaF to adult male rats did not induce DNA-strand breaks in testicular cells when measured by alkaline elution. Although plasma fluoride levels were as high as 12 ppm is rats given 84 mg/kg of NaF, testicular fluoride levels in most cases were only 10-20% of plasma levels. Fluoride did not accumulate in the testes after 5 daily treatments.
