Frontal Cerebral Blood Flow Deficits in Behavioral Variant Frontotemporal Dementia: Associations With Clinical Symptoms, Peripheral Vascular Biomarkers, and Neuroimaging Measures

CNS Neuroscience &Therapeutics, Volume 32, Issue 11, November 2026.
Frontal and temporal hypoperfusion is observed in frontotemporal dementia, showing spatial concordance with gray matter atrophy and hypometabolism of glucose. Frontal hypoperfusion correlates significantly with peripheral vascular biomarkers and clinical phenotypes.

Persisting Region‐Specific Microglia Activation and Synaptic Imbalance During Remission in a DSS‐Induced Colitis Model

Glia, Volume 74, Issue 11, November 2026.
Relapsing colitis region‐specific microglial states beyond remission. Cortical microglia remain pro‐inflammatory and synapse‐disruptive, while hippocampal microglia shift toward a reparative program that maintains neuronal circuit stability. ABSTRACT Ulcerative colitis (UC) patients experience cycles of active gut inflammation and remission, with ...

Obsessive–Compulsive Disorder: Comorbidity, Biomarkers, Circuits, and Treatment Strategies

MedComm, Volume 7, Issue 11, November 2026.
OCD has a high comorbidity with other psychiatric conditions, among which anxiety is the most frequent one. The shared genetic biomarkers and common neural circuits underlying the co‐occurrence of OCD and anxiety pave a new path for understanding the pathogenic mechanism of OCD and suggest tailored and integrative treatment therapies for OCD from the ...

Regularized Joint Reconstruction and Slab Combination for Accelerated Three‐Dimensional Multi‐Slab Diffusion‐Weighted Imaging Using Multi‐Scale Energy Models

Magnetic Resonance in Medicine, Volume 96, Issue 5, Page 2321-2335, November 2026.
ABSTRACT Purpose To jointly reconstruct high‐resolution diffusion‐weighted volumes and eliminate slab‐boundary artifacts while preserving fine anatomical detail from undersampled 3D multi‐slab k‐space acquisitions. Methods A bilinear forward model was formulated to describe the 3D multi‐slab acquisition, treating the image volume and slab excitation ...

Inferior Frontal Gyrus Alterations in Freezing of Gait in Parkinson's Disease Without Evidence for Overall Hemispheric Lateralization: A Systematic Review and Activation Likelihood Estimation Meta‐Analysis

European Journal of Neuroscience, Volume 64, Issue 9, November 2026.
Our systematic review included 108 neuroimaging articles examining freezing of gait in Parkinson's disease, with 33 included in the primary activation likelihood estimation meta‐analysis. We assessed spatial convergence and hemispheric lateralization of reported abnormalities, identifying the right inferior frontal gyrus as the main convergent region ...

Digital control for interleaved boost power factor correction (PFC) rectifiers

, 2014
Rectifiers with low power factor cause line interferences and reactive power. Hence, power factor correction (PFC) rectifiers have been established as front end stage of AC-DC converters. To increase the power level and reduce the high-frequency interferences two or more boost converters are operated in parallel with phase shifted switching cycles. For

Sex differences in the prefrontal cortex and muscle oxygenation during exercise until exhaustion in endurance‐trained individuals

Experimental Physiology, Volume 111, Issue 11, Page 5136-5153, 1 November 2026.
Abstract figure legend During cardiopulmonary exercise testing, the decline in oxygenation in the prefrontal cortex of women is striking. This crucial brain area is directly involved in planning motor tasks. The decline is particularly pronounced at higher exercise intensities, especially after reaching the respiratory compensation point or anaerobic ...
