A Hybrid Transfer Learning Framework for Brain Tumor Diagnosis

Advanced 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 ...

The Role of Glutamatergic and Dopaminergic Genes in Resistant Schizophrenia: A Systematic Review

American Journal of Medical Genetics Part B: Neuropsychiatric Genetics, EarlyView.
ABSTRACT Psychosis is a heterogeneous disorder, with approximately one‐third of patients experiencing treatment resistance, predominantly among individuals diagnosed with Schizophrenia. Treatment‐resistant schizophrenia (TRS) may stem from a distinct biological signature, involving abnormalities in the dopaminergic and glutamatergic systems.

Nasal Tuft Cell Markers Are Predictive of Overall Survival in Sinonasal Neuroendocrine and Sinonasal Undifferentiated Carcinomas

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Sinonasal neuroendocrine carcinoma (SNEC) and sinonasal undifferentiated carcinoma (SNUC) are rare aggressive malignancies with no established prognostic markers. Because features of POU2F3+ small cell lung carcinomas have been identified in both tumors, we evaluated immunostaining for POU2F3, a tuft cell transcription factor, and ...

Central hyperthyroidism due to an ectopic TSH-secreting pituitary tumor: a case report and literature review

Frontiers in Endocrinology
Ectopic thyroid-stimulating hormone (TSH)-secreting tumors are extremely rare, with only 15 reported cases in the literature. Herein, we described a 60-year-old female patient with thyrotoxicosis and elevated or unsuppressed levels of TSH. Family history

Hippocampal Seizure‐Related Burden is Associated with Accelerated Long‐Term Forgetting in Focal Epilepsy

Annals of Neurology, EarlyView.
Objective Memory impairment is a frequent comorbidity of focal epilepsy, incompletely explained by seizure frequency or structural pathology. Ictal and postictal hippocampal dysfunction disrupt memory processes, but their cumulative impact remains poorly quantified.

Memory and Plasma pTau217 Refine Prognosis in Down Syndrome

Annals of Neurology, EarlyView.
Individuals with Down syndrome (DS) are at high risk for Alzheimer's disease (AD), yet accessible tools for routine clinical screening of AD in individuals with DS remain limited. Using data from the Alzheimer Biomarker Consortium‐Down Syndrome (ABC‐DS), we show that integrating plasma pTau217 with performance on the modified cued recall task ...
