A Hybrid Transfer Learning Framework for Brain Tumor Diagnosis

open access: yesAdvanced Intelligent Systems, Volume 7, Issue 3, March 2025.
A novel hybrid transfer learning approach for brain tumor classification achieves 99.47% accuracy using magnetic resonance imaging (MRI) images. By combining image preprocessing, ensemble deep learning, and explainable artificial intelligence (XAI) techniques like gradient‐weighted class activation mapping and SHapley Additive exPlanations (SHAP), the ...

Correction of Ineffective Erythropoiesis and Normalization of Iron Homeostasis After Exagamglogene Autotemcel in Transfusion‐Dependent β‐Thalassemia

open access: yesAmerican Journal of Hematology, EarlyView.
ABSTRACT Exagamglogene autotemcel (exa‐cel) is a one‐time, ex vivo, CRISPR‐Cas9 gene edited cell therapy approved for patients with transfusion dependent β‐thalassemia (TDT) aged 12–35 years. In a Phase 3 study (CLIMB THAL‐111), exa‐cel treatment resulted in reactivation of fetal hemoglobin and increases in total hemoglobin, leading to transfusion ...

Diffusion MRI and α‐Synuclein Seed Amplification Status in Parkinson's Disease

open access: yesAnnals of Neurology, EarlyView.
Objective Positive α‐synuclein seed amplification assay (SAA) is a biomarker found in most people with Parkinson's disease (PD). We explored if free‐water (FW) imaging detects microstructural differences in the brains of patients with early PD with SAA+ or SAA– status.

A critical reappraisal of the carotid sinus and carotid bulb: Distinguishing neurohistological function from vascular geometry

open access: yesThe Anatomical Record, EarlyView.
This review redefines the carotid bulb (CB) as a variable geometric dilation shaped by hemodynamics and the carotid sinus (CS) as a conserved neurohistological baroreceptor field. Distinguishing these entities clarifies a century of anatomical confusion and links geometry, neurohistology, and clinical interpretation within a unified framework ...

Ultrasmall Fe‐curcumin immunomodulators reinvigorate CAR‐T cells to potentiate solid tumor immunotherapy by mitigating cell exhaustion and senescence

open access: yesBMEMat, EarlyView.
This work discovered a novel research that ultrasmall Fe‐curcumin immunomodulators could reinvigorate CAR‐T cells to potentiate solid tumor immunotherapy by mitigating cell exhaustion and senescence. Abstract CAR‐T cell immunotherapy has achieved exciting success in hematologic malignancies, but the therapeutic efficacy is relatively limited in solid ...

Spatially resolved 23Na magnetic resonance dispersion measurement in porous media

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Quantitative 23Na MRI was employed to analyze dispersion in realistic core plug samples and was compared with the conventional breakthrough curve. 23Na MRI provided a more effective aassessment of core plug heterogeneity than the conventional method. Abstract Tracer tests are widely used in the petroleum industry to assess reservoir core plugs, relying
