Understanding Mechanisms of Whole Brain and Regional Grey Matter Atrophy in Children With MOGAD

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To investigate the mechanisms driving whole brain and regional grey matter (GM) volume changes along with their clinical correlates in paediatric myelin oligodendrocyte glycoprotein antibody (MOG‐Ab)–associated disease (MOGAD). Methods One‐hundred‐nine paediatric MOGAD patients from two UK centres underwent MRI at attack nadir and ...

Exploring covalently bonded diamondoid particles with valence photoelectron spectroscopy

, 2013
We investigated the valence electronic structure of diamondoid particles in the gas phase, utilizing valence photoelectron spectroscopy. The samples were singly or doubly covalently bonded dimers or trimers of the lower diamondoids.

Electronic structure of FeSe monolayer superconductors [PDF]

, 2016
We review a variety of theoretical and experimental results concerning electronic band structure of superconducting materials based on FeSe monolayers. Three type of systems are analyzed: intercalated FeSe systems A_xFe_2Se_{2-x}S_x and [Li_{1-x}Fe_xOH ...

Multimodal Autonomic Biomarkers Predict Phenoconversion in Pure Autonomic Failure

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Pure autonomic failure (PAF) presents with autonomic failure without other neurological features. A third develop central neurological features, fulfilling criteria for multiple system atrophy (MSA) and Lewy body diseases (LBD), including Parkinson's disease and Dementia with Lewy bodies.

Electronic structure of periodic curved surfaces -- topological band structure

, 2001
Electronic band structure for electrons bound on periodic minimal surfaces is differential-geometrically formulated and numerically calculated. We focus on minimal surfaces because they are not only mathematically elegant (with the surface characterized ...

Real‐World Cost‐Effectiveness of a Standardized Education and Exercise Therapy Program for Hip and Knee Osteoarthritis Compared to Usual Care

Arthritis Care &Research, EarlyView.
Objective We estimated the real‐world cost‐effectiveness of a standardized education and exercise therapy program (GLA:D) compared to usual care (UC) for people managing hip and/or knee osteoarthritis (HKOA). Methods We used a prospective matched cohort design to recruit people (aged >45 years) diagnosed with HKOA who used GLA:D or UC (not on a ...

Rapid Detection of Benzo[a]pyrene in Extra Virgin Olive Oil Using Fluorescence Spectroscopy

Molecules, 2023
Extra virgin olive oil (EVOO) should be naturally free of polycyclic aromatic hydrocarbon (PAH) contamination. PAHs are carcinogenic and toxic, and may cause human health and safety problems. This work aims to detect benzo[a]pyrene residues in EVOO using

Well‐Dispersed Nickel‐ and Zinc‐Tailored Electronic Structure of a Transition Metal Oxide for Highly Active Alkaline Hydrogen Evolution Reaction

Advances in Materials, 2019
The practical scale‐up of renewable energy technologies will require catalysts that are more efficient and durable than present ones. This is, however, a formidable challenge that will demand a new capability to tailor the electronic structure.
