Handheld brain scanner could safeguard contact sport athletes from deadly brain bleeds

The Infrascanner 2000 has the ability to spot deadly brain bleeds just moments after the injury happening, with up to 90 per cent accuracy. It has been used for years by armed forces in the US and China.

Publication date: Available online 14 December 2019Source: NeuroImageAuthor(s): Daan Christiaens, Jelle Veraart, Lucilio Cordero-Grande, Anthony N. Price, Jana Hutter, Joseph V. Hajnal, J-Donald TournierAbstractProbing microstructure with diffusion magnetic resonance imaging (dMRI) on a scale orders of magnitude below the imaging resolution relies on biophysical modelling of the signal response in the tissue. The vast majority of these biophysical models of diffusion in white matter assume that the measured dMRI signal is the sum of the signals emanating from each of the constituent compartments, each of which exhibits a d...

This study aims, first, to validate a retrospectively-gated implementation of the DENSE method for assessing brain tissue pulsations as a physiological marker, and second, to use the acquired measurements to explore intracranial volume dynamics. We acquired repeated measurements of cerebral volumetric strain in 8 healthy subjects, and internally validated these measurements by comparing them to spinal CSF stroke volumes obtained in the same scan session.Peak volumetric strain was found to be highly repeatable between scan sessions. First/second measured peak volumetric strains were: (6.4 ± 1.7)x10−4/(6.7...

Here we evaluated the relationship between a four-point visual assessment system referred to as 'ASL scores' using AS...

Publication date: January 2020Source: The Annals of Thoracic Surgery, Volume 109, Issue 1Author(s): Simone Furia, Nazarena Nannini, Anna Pascarella, Cristiano BredaRosai-Dorfman disease (RDD) is a rare benign disorder of the histiocytes, affecting lymph nodes in its classic form. Extranodal RDD is considered the uncommon subtype and potentially impairs all tissues and intrathoracic organs. In our report, a 18F-fluorodeoxyglucose positron emission tomography scan of a mediastinal mass infiltrating the lungs and of widespread lesions suggested the presence of a metastatic disease. Open thoracic biopsy was required for immuno...

ConclusionsOccult nodal disease was frequently identified in peripheral N1 stations (11-13) in patients with small (≤2 cm) clinical N0 NSCLC. Hilar lymphadenectomy is essential for accurate staging in the management of patients with small clinical N0 NSCLC.

In this study, potatoes, carrots and ginger roots were selected as representative vegetables and subjected to RF heating to obtain their heating pattern. At the meantime, the processes were simulated with the COMSOL Multiphysics® software package with both an imported 3D scanned &reconstructed geometry and a similar regular-shaped geometry, which was close to the original shape of the various food samples for comparison. Results showed that computer simulation with geometry obtained by using 3D scanning could accurately reproduce the experimental results for the hot/cold spot locations and temperature values. For t...

Nevertheless, The mechanism by which β-glucanase improves the quality of fermented barley flour-based products is still poorly understood. The gluten microcosmic structure, molecular structure and yeast gas production capacity were investigated using Fourier transform infrared (FT-IR) spectroscopy, Raman spectroscopy, Scanni...

This study suggests that fissures can provide a pathway for microorganisms to enter the dentinal tubules, potentially resulting in local pulpal inflammation. It appears that in healthy teeth, vital odontoblasts react by producing reactionary (tertiary) dentin, which lacks patent tubules and thus provides a proper seal.
