The Evaluation of Optic Nerves Using 7 Tesla “Silent” Zero Echo Time Imaging in Patients with Leber’s Hereditary Optic Neuropathy with or without Idebenone Treatment

Magnetic Resonance Imaging (MRI) of the Optic Nerve is difficult due to the fine extended nature of the structure, strong local magnetic field distortions induced by anatomy, and large motion artefacts associated with eye movement. To address these problems we used a Zero Echo Time (ZTE) MRI sequence with an Adiabatic SPectral Inversion Recovery (ASPIR) fat suppression pulse which also imbues the

Comparison of multi echo T2 relaxation and steady state approaches for myelin imaging in the central nervous system

The traditional approach for measuring myelin-associated water with quantitative magnetic resonance imaging (MRI) uses multi-echo T2 relaxation data to calculate the myelin water fraction (MWF). A fundamentally different approach, abbreviated “mcDESPOT”, uses a more efficient steady-state acquisition to generate an equivalent metric (fM). Although previous studies have demonstrated inherent instab

Silent zero TE MR neuroimaging: Current state-of-the-art and future directions

Magnetic Resonance Imaging (MRI) scanners produce loud acoustic noise originating from vibrational Lorentz forces induced by rapidly changing currents in the magnetic field gradient coils. Using zero echo time (ZTE) MRI pulse sequences, gradient switching can be reduced to a minimum, which enables near silent operation. Besides silent MRI, ZTE offers further interesting characteristics, including

Radial Interstices Enable Speedy Low-volume Imaging

• Standard MRI methods acquire Fourier-encoded data on a regularly spaced Cartesiangrid. Noncartesian MRI methods abandon this grid and instead acquire data alongarbitrary trajectories in k-space, which can lead to advantages such as motion robustnessand more flexible pulse sequence design.• Zero Echo Time (ZTE) imaging is a specialised form of MRI with an inherently noncartesian three-dimensional

System and method for performing motion-insensitive and quiet three-dimensional magnetic resonance imaging

A method for generating motion-corrected medical images includes obtaining, via a processor, k-space data of a region of interest acquired by a magnetic resonance imaging system utilizing a 3D radial pulse sequence with ZTE acquisition including optional magnetization preparation pulses. The method also includes sampling, via the processor, the k-space data to obtain a plurality of interleaved k-s

Grey Matter Segmentation in Spinal Cord MRIs via 3D Convolutional Encoder Networks with Shortcut Connections

Segmentation of grey matter in magnetic resonance images of the spinal cord is an important step in assessing disease state in neurological disorders such as multiple sclerosis. However, manual delineation of spinal cord tissue is time-consuming and susceptible to variability introduced by the rater. We present a novel segmentation method for spinal cord tissue that uses fully convolutional encode

Constructions of migrant victims of labor exploitation in Nordic court cases

The aim of this article is to explore how courts produce certain representations of victims of labor exploitation in the Nordic context based on court judgements from Denmark, Finland, Norway and Sweden. To achieve this, we analyze and compare criminal court judgements focused on the exploitation of migrant workers by asking: How are ‘victims’ of labor exploitation represented in Nordic court judg

Evaluating the affinity and kinetics of small molecule glycomimetics for human and mouse galectin-3 using surface plasmon resonance

Galectin-3 is a beta-galactoside-binding mammalian lectin that is one of a 15-member galectin family that can bind several cell surface glycoproteins via its carbohydrate recognition domain (CRD). As a result, it can influence a range of cellular processes including cell activation, adhesion and apoptosis. Galectin-3 has been implicated in various diseases, including fibrotic disorders and cancer,

Novel inhibitory effect of galectin-3 on the respiratory burst induced by Staphylococcus aureus in human neutrophils

Among the responders to microbial invasion, neutrophils represent the earliest and perhaps the most important immune cells that contribute to host defense with the primary role to kill invading microbes using a plethora of stored anti-microbial molecules. One such process is the production of reactive oxygen species (ROS) by the neutrophil enzyme complex NADPH-oxidase, which can be assembled and a

Safety and pharmacokinetics of GB1211, an oral galectin-3 inhibitor : a single- and multiple-dose first-in-human study in healthy participants

PURPOSE: Galectin-3, a β-galactoside-binding lectin, plays a key role in several cellular pathways involved in chronic inflammation, heart disease and cancer. GB1211 is an orally bioavailable galectin-3 inhibitor, developed to be systemically active. We report safety and pharmacokinetics (PK) of GB1211 in healthy participants.METHODS: This phase 1, double-blind, placebo-controlled, first-in-human

Access to justice and social rights for victims of trafficking and labour exploitation in Sweden

This chapter delves into the challenges encountered by victims of human trafficking and other forms of labour exploitation in Sweden as they struggle to access social rights and justice. By drawing from theories of victimisation as an interactional process, the study examines the role of professionals such as government agents, social services, unions, and NGOs as facilitators in assisting victimsThis chapter delves into the challenges encountered by victims of human trafficking and other forms of labour exploitation in Sweden as they struggle to access social rights and justice.

Acute and Long-Term Changes in Blood-Borne Biomarkers in Response to Dynamic Standing in Nonambulant Children With Cerebral Palsy

PURPOSE: To investigate acute and long-term changes in hormonal and inflammatory biomarkers in nonambulant children with cerebral palsy in response to dynamic standing exercise.METHODS: Fourteen children with severe cerebral palsy were recruited. Anthropometrics and body composition measures were obtained. Physical activity levels before the study were assessed using hip-worn accelerometry. All ch

"It is something that gives us hope" : Lived experience among parents to children with cerebral palsy who are non-ambulant of the phenomenon physical activity, with or without the use of a novel dynamic standing device

INTRODUCTION: Regular physical activity confers health benefits for all. Parents commonly want their children to be physically active, and want to be physically active themselves, but children with cerebral palsy (CP) who are non-ambulant face challenges, and they need support to be physically active. Dynamic standing in the novel motorized assistive device Innowalk has positive effects in childre

Spatially Guided and Single Cell Tools to Map the Microenvironment in Cutaneous T-Cell Lymphoma

Mycosis fungoides (MF) and Sézary syndrome (SS) are two closely related clinical variants of cutaneous T-cell lymphomas (CTCL). Previously demonstrated large patient-to-patient and intra-patient disease heterogeneity underpins the importance of personalized medicine in CTCL. Advanced stages of CTCL are characterized by dismal prognosis, and the early identification of patients who will progress re
