Super-resolution track-density imaging studies of mouse brain: Comparison to histology
The recently proposed track-density imaging (TDI) technique was introduced as a means to achieve superresolution using diffusion MRI. This technique is able to increase the spatial resolution of the reconstructed images beyond the acquired MRI resolution by incorporating information from whole-brain fibre-tracking results. It not only achieves super-resolution, but also provides very high anatomical contrast with a new MRI contrast mechanism. However, the anatomical information-content of this novel contrast mechanism has not yet been assessed. In this work, we perform such a study using diffusion MRI of ex vivo mouse brains acquired at 16.4T, to compare the results of the super-resolution TDI technique with histological staining (myelin and Nissl stains) in the same brains. Furthermore, a modified version of the directionally-encoded colour TDI map using short-tracks is introduced, which reduces the TDI intensity dynamic range, and therefore enhances the directionality colour-contrast. Good agreement was observed between structures visualised in the superresolution TDI maps and in the histological sections, supporting the anatomical information-content of the images generated using the TDI technique. The results therefore show that the TDI methodology does provide meaningful and rich anatomical contrast, in addition to achieving super-resolution. Furthermore, this study is the first to show the application of TDI to mouse brain imaging: the high-resolution, high-quality images demonstrate the useful complementary information that can be achieved using super-resolution TDI
Atomic and Electronic Structure of a Rashba - Junction at the BiTeI Surface
The non-centrosymmetric semiconductor BiTeI exhibits two distinct surface
terminations that support spin-split Rashba surface states. Their ambipolarity
can be exploited for creating spin-polarized - junctions at the
boundaries between domains with different surface terminations. We use scanning
tunneling microscopy/spectroscopy (STM/STS) to locate such junctions and
investigate their atomic and electronic properties. The Te- and I-terminated
surfaces are identified owing to their distinct chemical reactivity, and an
apparent height mismatch of electronic origin. The Rashba surface states are
revealed in the STS spectra by the onset of a van Hove singularity at the band
edge. Eventually, an electronic depletion is found on interfacial Te atoms,
consistent with the formation of a space charge area in typical -
junctions.Comment: 5 pages, 4 figure
Identification of sixteen grapevine rootstocks by RFLP and RFLP analysis of nuclear DNA extracted from the wood
Sixteen rootstocks of the Vitis genus have been identified by the RFLP analysis methodology with the restriction enzyme HinfI. Uniques or moderately repeated DNA sequences of the nuclear genome of the Chardonnay V. vinifera variety were used as probes. RFLP analysis of 5 clones of SO 4 (V. berlandieri x V. riparia) and of 3 clones of 41 B Mgt (V. berlandieri x V. vinifera) with 4 probes and HinfI did not lead to any polymorphism. This is not surprising because of the vegetative origin of the clones. A simple method of nuclear DNA extraction of wood is described for the grapevine. We propose now the RFLP analysis methodology to complement or to replace in certain cases the ampelographical methods of identification of the rootstocks. The extension of this application to the V. vinifera varieties is considered.Identification de 16 porte-greffes de vigne par analyse RFLP, et analyse RFLP d'ADN nuclĂ©aire extrait Ă partir du boisNous avons identifiĂ© 16 porte-greffes du genre Vitis par la mĂ©thodologie d'analyse du polymorphisme de longueur des fragments de restriction (RFLP) de l'ADN avec l'enzyme de restriction HinfI. Pour cela, nous avons utilisĂ© comme sondes des fragments d'ADN uniques ou peu rĂ©pĂ©tĂ©s du gĂ©nome de la variete Chardonnay de Vitis vinifera. L'analyse RFLP de cinq clones de SO 4 (V. berlandieri x V. riparia) et de trois clones de 41 B Mgt (V. berlandieri x V. vinifera) avec quatre sondes RFLP et l'enzyme HinfI n'a pas permis de diffĂ©rencier les clones d'un mĂȘme hybride, dont les genomes sont extrĂȘmement proches puisqu'ils sont obtenus de façon vĂ©gĂ©tative. Nous prĂ©sentons aussi une mĂ©thode simple d'extraction d'ADN nuclĂ©aire Ă partir du bois de vigne. Les analyses RFLP de cet ADN ont donnĂ© des rĂ©sultats identiques Ă ceux obtenus avec l'ADN des feuilles. Nous sommes maintenant en mesure de proposer que la mĂ©thodologie d'analyse RFLP complĂšte ou remplace dans certains cas les mĂ©thodes ampĂ©lographiques d'identification des portegreffes du genre Vitis. L'Ă©largissement de cette application est envisagĂ© pour les varietes de Vitis vinifera
Experiences and needs of direct support staff working with people with intellectual disabilities during the COVID-19 pandemic:A thematic analysis
Background The present study aimed to explore the experiences and needs of direct support staff during the initial stage of the COVIDâ19 lockdown in the Netherlands. Method Overall, eleven direct support staff were recruited from five intellectual disability services to participate in this descriptive qualitative study. They recorded 34 audio messages during the considered period. Thematic analysis was used to analyse these audio recordings. Results Four themes emerged: (1) Emotional impact, which pertained to various emotions they experienced in their work; (2) Cognitive impact, which referred to challenges and changes they had undergone in their work; (3) Practical impact, which centred on the practical impact of the pandemic on their work; and (4) Professional impact, which concerned their experiences with other professionals. Conclusions This study provides valuable insights into the experiences and needs of direct support staff during the COVIDâ19 pandemic, which, in turn, can help inform practice in preparation for a second wave of COVIDâ19 or another future pandemic
The experiences of psychologists working with people with intellectual disabilities during the COVID-19 crisis
BACKGROUND: The aim of this study was to explore the experiences of psychologists working with people with intellectual disabilities during the initial stage of the COVIDâ19 lockdown in the Netherlands. METHOD: Five psychologists, who were affiliated with three intellectual disability services, participated in this descriptive qualitative study. Overall, they recorded 22 audio messages during the period under examination, which were analysed using thematic analysis. RESULTS: Three themes were identified: (a) Working from home; (b) Adapting to the new reality; and (c) Advising and coaching support staff. CONCLUSIONS: This study provides critical insights into the experiences of psychologists working with people with intellectual disabilities during the initial stage of the COVIDâ19 lockdown. These insights can help policymakers and practitioners to prepare for either a potential second wave of COVIDâ19 or a future pandemic
Arthroscopic treatment of an intra-articular hemangioma in the posterior compartment of the knee
AbstractWe report the case of a 37-year-old patient presenting with knee pain and recurrent effusion without instability due to an intra-articular hemangioma in the posterior compartment of the knee. MRI showed features suggesting a diagnosis of hemangioma. Arthroscopic excision of the tumor was performed and the diagnosis was confirmed histologically. There was no recurrence after 5 years of follow-up
Picosecond fluctuating protein energy landscape mapped by pressureâtemperature molecular dynamics simulation
Microscopic statistical pressure fluctuations can, in principle, lead to corresponding fluctuations in the shape of a protein energy landscape. To examine this, nanosecond molecular dynamics simulations of lysozyme are performed covering a range of temperatures and pressures. The well known dynamical transition with temperature is found to be pressure-independent, indicating that the effective energy barriers separating conformational substates are not significantly influenced by pressure. In contrast, vibrations within substates stiffen with pressure, due to increased curvature of the local harmonic potential in which the atoms vibrate. The application of pressure is also shown to selectively increase the damping of the anharmonic, low-frequency collective modes in the protein, leaving the more local modes relatively unaffected. The critical damping frequency, i.e., the frequency at which energy is most efficiently dissipated, increases linearly with pressure. The results suggest that an invariant description of protein energy landscapes should be subsumed by a fluctuating picture and that this may have repercussions in, for example, mechanisms of energy dissipation accompanying functional, structural, and chemical relaxation
