Cerebral Infarction: Epidemiology, Classification, Mechanisms, Diagnosis, and Management

open access: yesMedComm, Volume 7, Issue 4, April 2026.
Within minutes after ischemia onset, deprivation of oxygen and glucose leads to rapid ATP depletion, resulting in failure of Na+/K+‐ATPase activity and membrane depolarization. This ionic imbalance promotes uncontrolled synaptic release of glutamate and excessive activation of postsynaptic NMDA and AMPA receptors.

Wake-up stroke: clinical characteristics, imaging findings, and treatment option – an update.

open access: yesFrontiers in Neurology, 2014
About 25% of all strokes occur during sleep, i.e. without knowledge of exact time of symptom onset. According to licensing criteria, this large group of patients is excluded from treatment with rt-PA, the only specific stroke treatment proven effective ...

“Time Is Brain” – for Cell Therapies

open access: yesAdvanced Science, Volume 13, Issue 6, 30 January 2026.
The concept that “time is brain” extends to stem cell therapy for stroke. Evidence across preclinical and clinical studies indicates that delivery timing shapes graft survival, integration, and efficacy by matching the evolving post‐stroke microenvironment.

Brain MRI Radiomic First‐Order Features for Presurgical Prediction of Meningioma Grading

open access: yesJournal of Neuroimaging, Volume 36, Issue 1, January/February 2026.
ABSTRACT Background and Purpose Grading meningioma guides treatment choices from follow‐up to surgical resection with adjuvant radiation. Radiomics may offer a non‐invasive alternative to biopsies. We assessed radiomic features (RFs) for distinguishing Grade 1 and Grade 2 meningiomas on preoperative multiparametric MRI. Methods Presurgical T1‐weighted (

Are Big Prostates a Challenge? Correlation Between Prostate Volume and Detection Rate in Fusion Biopsy of the Prostate

open access: yesAdvances in Urology, Volume 2026, Issue 1, 2026.
Background This study investigates the relationship between prostate cancer (PCa) detection rates and prostate volume. Prostate volume may influence the diagnostic performance of MRI–ultrasound (MRI–US) fusion biopsy. Enlarged prostate glands present specific challenges, including reduced specificity of prostate‐specific antigen (PSA), anatomical ...
