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 ±

Gravity‐Dependent Modulation of Downbeat Nystagmus: Insights From Velocity‐Storage Dysfunction
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Downbeat nystagmus varies with head position, a phenomenon termed gravity‐dependent modulation. We aimed to clarify its mechanism using a velocity‐storage model. Methods In 10 patients with downbeat nystagmus due to cerebellar disorders, we recorded eye movements at different pitch‐ and roll‐axis head positions.

Experimental Determination of Inertia Moments on a Rotary Wing Unmanned Aerial Vehicle [PDF]
, 2018 Momenti tromosti nekog tijela, primjerice letjelice, ključni su parametar njegove dinamike jer predstavljaju mjeru otpora rotacijskom gibanju. Što je letjelica tromija, teže će biti započeti, ali i zaustaviti njezinu rotaciju.

Blocking effect and odd-even differences in the moments of inertia of rare-earth nuclei
, 1994 A phenomenological analysis of the experimental odd-even differences in the moments of inertia, deltaJ/J, of well-deformed rare-earth nuclei is reviewed, which reveals that there exist large fluctuations in deltaJ/J with the blocked levels in odd-A ...

Arthritis Care &Research, EarlyView.Objective Knee osteoarthritis (OA) commonly affects individuals with type 2 diabetes (T2DM) and is associated with increased risk of diabetes‐related complications. To better understand potential mechanisms, we examined the association between symptomatic knee OA and glycemic control in individuals with T2DM.

To the nature of 0+ excitations in deformed nuclei of actinides
Ядерна фізика та енергетика, 2016 The excitation spectra in the deformed nucleus 232U have been studied by means of the (p, t) reaction. 0+ assignments for 13 excited states and up to spin 6+ for other states are made from the angular distributions of tritons and the coupled-channel ...

Arthritis Care &Research, EarlyView.Objective Clinical response to mycophenolic acid (MPA) is highly heterogeneous; thus, therapeutic drug level monitoring (TDM) may help improve treatment efficacy. This systematic review and meta‐analysis examined therapeutic ranges for MPA levels associated with better outcomes and safety in patients with systemic lupus erythematosus (SLE ...
