T1 Over Squared Proton Density Ratio to Characterize Multiple Sclerosis Lesions

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Differentiating remyelinated from demyelinated lesions in MS remains challenging without histological confirmation. This study introduces the T1‐to‐PD2 ratio (TPR) imaging approach and evaluates its ability to characterize MS lesions alongside other quantitative MRI (qMRI) metrics. Methods Thirty individuals with MS (mean age: 47.5 ±

Le cimetière du second âge du Fer du « Bas des Aouches » à Gisy-les-Nobles (Yonne) : découvertesanciennes et fouilles modernes

Revue Archéologique de l’Est, 2015
The study considers the metal artefacts in a graveyard discovered by chance at the end of the 19th century and the remains of inhumation graves excavated in 1978 in the same location. Despite the lack of surviving information, the artefacts found allow a

Quantitative MRI Uncovers Subtle Cortical Damage in Myelin Oligodendrocyte Glycoprotein Antibody‐Associated Disease

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To determine whether myelin‐sensitive quantitative MRI reveals microstructural abnormalities in normal‐appearing cortex (NACtx) in myelin oligodendrocyte glycoprotein antibody–associated disease (MOGAD), indicating that conventional MRI underestimates remission residual cortical injury.

Artificial Intelligence in Systemic Sclerosis: Clinical Applications, Challenges, and Future Directions

Arthritis Care &Research, EarlyView.
Systemic sclerosis (SSc) is a rare autoimmune disease defined by immune dysregulation, vasculopathy, and progressive fibrosis of the skin and internal organs. Despite advances in care, major complications such as interstitial lung disease (ILD) and myocardial involvement remain the leading causes of morbidity and mortality.

Microstructural Evolution and Vacancy Defect Formation in Mn–Mo–Ni RPV Steel Under Low Cycle Fatigue: Insights From EBSD and PALS

Advanced Engineering Materials, EarlyView.
Low‐cycle fatigue damage in Mn–Mo–Ni reactor pressure vessel steel is examined using a combined electron backscatter diffraction and positron annihilation lifetime spectroscopy approach. The study correlates texture evolution, dislocation substructure development, and vacancy‐type defect formation across uniform, necked, and fracture regions, providing

Genetics of iron regulation and the possible role of iron in Parkinson's disease

Neurobiology of Disease, 2008
Parkinson's disease (PD) is acknowledged as the second most common neurodegenerative disorder after Alzheimer's Disease. Older age may be the only unequivocal risk factor for PD although the male to female ratio is consistently greater than 1 in ...

Infant Iron Stores at Three Months of Age Are Associated With Maternal Hepcidin and Serum Ferritin Concentrations During the Second Trimester

Current Developments in Nutrition, 2022
OBJECTIVES: To determine if relationships exist between maternal concentrations of hepcidin and serum ferritin (SF) throughout pregnancy and infant SF concentrations at 3 months of age. METHODS: Pregnant women from Edmonton and Calgary, Alberta, Canada were recruited into the Alberta Pregnancy Outcomes and Nutrition (APrON) cohort study from 2009–2012.

Enhancing Strength and Electrical Conductivity in Al–Zr–Sc Conductor Alloys Through Sn and Sr Microalloying and Two‐Step Aging Treatment

Advanced Engineering Materials, EarlyView.
Trace additions of Sn and Sr combined with a two‐step aging treatment are shown to enhance the microstructure and performance of Al–Zr–Sc conductor alloys. Strength and electrical conductivity increase concurrently through accelerated precipitation of fine Al3(Sc, Zr) precipitates and improved dislocation resistance, offering a cost‐effective pathway ...

THE FIND OF PRE-VIKING AGE CHARRED GRAINS FROM FORT-SETTLEMENT IN TARTU; pp. 33–53 [PDF]

Eesti Arheoloogiaajakiri, 2016
From the occupation layer of settlement adjacent to Tartu fort, deposited at some point between the 7th to 9th centuries, a soil sample was taken. In addition to other finds, charred plant macrofossils were obtained. These consisted of eight taxa. Barley
