Article Abstract
The present study evaluates the effects of agmatine on histopathological damage following traumatic injury using a clinically relevant model of diffuse brain injury. A total of 27 male Sprague-Dawley rats weighing 200-225 g were anaesthetised and subjected to head trauma using Marmarou's impact-acceleration model. The rats were then separated into two main groups: one was treated with agmatine and the other with saline for up to 4 days immediately after head trauma. Rats from both groups were killed 1, 3 or 8 days post-injury. The brains were examined histopathologically and scored according to the axonal, neuronal and vascular changes associated with diffuse brain injury. There were no significant differences between the groups at 1 day or 3 days after trauma, but evaluation after 8 days revealed a significant improvement in the group treated with agmatine. Our data indicate that agmatine has a beneficial effect in diffuse brain injury and should be trialled for therapeutic use in the management of this condition.

Introduction: Radiosurgery targeting the thalamus has long been used to treat refractory pain, with medial thalamotomy as a key approach. Traditionally, targeting relied on indirect methods based on anatomical atlases, which do not account for individual variations in brain connectivity. Recent advances in connectomic-guided stereotactic radiosurgery have improved precision in the treatment of movement disorders, but their application to pain management remains underexplored.

Background: Anaplastic lymphoma kinase (ALK)-positive primary CNS anaplastic large cell lymphoma (ALCL) is an extremely rare pediatric malignancy. Its radiological appearance often mimics infectious or glial lesions, complicating diagnosis and delaying treatment.
Observations: The authors report the case of a 10-year-old immunocompetent female who presented with absence seizures and vomiting.

Anti-Aβ antibodies are important tools for identifying structural features of aggregates of the Aβ peptide and are used in many aspects of Alzheimer's disease (AD) research. Our laboratory recently reported the generation of a polyclonal antibody, pAb2AT-L, that is moderately selective for oligomeric Aβ over monomeric and fibrillar Aβ and recognizes the diffuse peripheries of Aβ plaques in AD brain tissue but does not recognize the dense fibrillar plaque cores. This antibody was generated against 2AT-L, a structurally defined Aβ oligomer mimic composed of three Aβ-derived β-hairpins arranged in a triangular fashion and covalently stabilized with three disulfide bonds.

Positron Emission Tomography (PET) is a critical imaging modality in nuclear medicine but requires radioactive tracer administration, which increases radiation exposure risks. While recent studies have investigated MR-guided low-dose PET denoising, they neglect two critical factors: the synergistic roles of multicontrast MR images and disease-specific denoising requirements. In this work, we propose a diffusion model that integrates T1-weighted, T2 fluid attenuated inversion recovery (T2 FLAIR), and hippocampal-optimized (T2 HIPPO) MR sequences to achieve ultra-low-dose PET denoising tailored for temporal lobe epilepsy (TLE).
