fMRI and DTI in delayed development of number processing.

[fMRI and DTI in delayed development of number processing]. Radiologe. 2015 Aug 7; Authors: Krick CM, Neuhaus A, Klewin C, Wörner T, Kreis S, Reith W Abstract The neuronal correlate of the current cultural performance arose from developmental processes that can be observed by functional and anatomical magnetic resonance imaging. The velocity of these maturation processes occurs differently between adolescents, causing implications for both school career and academic performance. Regarding spatial-numerical cognition the myelinization of the superior longitudinal bundle appears to be crucial because this fiber connection intermediates between the linguistic nature of number words and conception of their spatial-numerical magnitude. The neuroscientific observation of anatomical brain maturation and its influence on school-relevant number processing may be helpful for educational purposes as well as for school psychology.

Authors: Bailey HE Abstract A severe and unusual complication found in children with influenza is an acute necrotizing encephalopathy. A 20-month-old female with no significant past medical history was admitted to our facility, presenting with a 4-day history of worsening fever, upper respiratory symptoms, new-onset altered mental status and episodes of extensor posturing. The initial concern was a dystonic reaction secondary to promethazine following a recent diagnosis of influenza A virus. A head computed tomography scan indicated concern for widespread edema, and the video EEG revealed focal slowing in the front...

In this study, a ten ‐gram‐scale facile method is developed to synthesize organogadolinium complex nanoparticles (i.e., reductive bovine serum albumin stabilized Gd‐salicylate nanoparticles, GdSalNPs‐rBSA) with highr1 value of 19.51 mm−1 s−1 and very lowr2/r1 ratio of 1.21 (B0 = 1.5 T) for high ‐contrastT1‐weighted MRI of tumors. The GdSalNPs‐rBSA nanoparticles possess more advantages including low synthesis cost (≈0.54 USD per g), long in vivo circulation time (t1/2 = 6.13 h), almost no Gd3+ release, and excellent biosafety. Moreover, the GdSalNPs ‐rBSA nanoparticles demonstrate excellent...

Frontotemporal lobar degeneration (FTLD) is a neurodegenerative disorder characterized by behavioral changes, language abnormality, as well as executive function deficits and motor impairment. In about 30–50% of FTLD patients, an autosomal dominant pattern of inheritance was found with major mutations in the MAPT, GRN, and the C9orf72 repeat expansion. These mutations could lead to neurodegenerative pathology years before clinical symptoms onset. With potential disease-modifying treatments that are under development, non-invasive biomarkers that help determine the early brain changes in presymptomatic FTLD patients w...

Schizophrenia is a severe mental disorder with often a chronic course. Neuroimaging studies report brain abnormalities in both white and gray matter structures. However, the relationship between microstructural white matter differences and volumetric subcortical structures is not known. We investigated 30 long-term treated patients with schizophrenia and schizoaffective disorder (mean age 51.1 ± 7.9 years, mean illness duration 27.6 ± 8.0 years) and 42 healthy controls (mean age 54.1 ± 9.1 years) using 3 T diffusion and structural magnetic resonance imaging. The free-water imaging method was used to mo...

Conclusions: Paraspinal muscles evaluated with MRI were more significantly associated with the pathology of ASD compared with appendicular skeletal muscle evaluations with dual-energy x-ray absorptiometry. The present study indicates that multifidus and erector muscles significantly influenced the maintenance of the pelvic alignment. Level of Evidence: Level III.

AbstractAims/IntroductionType 2 diabetes mellitus (T2DM) is a specific risk factor for intracranial atherosclerosis. The purpose of this study is to investigate the relationship between T2DM, especially uncontrolled glycemia and intracranial plaque characteristics using high ‐resolution magnetic resonance imaging (HR‐MRI).Materials and MethodsA total of 263 patients (182 male; mean age = 62.6 ± 11.5 years) with intracranial atherosclerotic plaques detected on HR‐MRI from December 2017 to March 2019 were included in this study. Patients were divided into different groups: first, patients with and without T2DM; ...

ConclusionsWe aim to study the timeline and transition from uncomplicated hypertension to HHD and HFpEF. In order to identify subjects prone to develop HHD and HFpEF, we want to find biomarkers and cardiac imaging variables to explain disease progression. Ultimately, we aim at finding new pathways to prevent HFpEF.
