An eye on long‐duration spaceflight: Controversies, countermeasures and challenges

Experimental Physiology, EarlyView.
Abstract Space flight‐associated neuroocular syndrome (SANS) is a consequence of long‐duration space flight and is detected in two‐thirds of astronauts. In‐flight, this can cause a change in the refraction of the eyes, requiring graded hypermetropic ‘superfocus adjustable’ glasses, optic nerve head oedema and choroidal folds.

Brain strain: Blood flow and metabolism in environmental extremes

Experimental Physiology, EarlyView.
Abstract This narrative review compares and contrasts the most commonly encountered environmental stressors on human cerebrovascular functioning. From high altitude and space, extreme apnoea, heat and cold stress, the impact of these stressors on the regulation of cerebral blood flow (CBF) and oxygen metabolism (CMRO2${\mathrm{CM}}{{\mathrm{R}}_ ...

Pharmacological manipulation of the immediate effects of spinal trauma in neonatal rats reveals a crucial role for TRPV4 receptors

The Journal of Physiology, EarlyView.
Abstract figure legend A, schematic illustration of the ventral aspect of an ex vivo preparation of the entire CNS from a neonatal rat subjected to a calibrated thoracic impact. The trauma induced a large depolarising injury potential (DIP, black trace) recorded from the L5 ventral root (VRrL5), which was markedly reduced by transient receptor ...

Inter‐Individual Differences in T1, T2, and Proton Density Using Quantitative Synthetic Imaging for 1H‐MRS Quantification

Magnetic Resonance in Medicine, Volume 95, Issue 5, Page 2489-2499, May 2026.
ABSTRACT Purpose Metabolite concentrations can be determined from proton magnetic resonance spectroscopy (1H‐MRS) data using water as an internal reference. This calculation requires tissue‐specific water T1 and T2 relaxation constants and proton density (PD).

Early olfactory dysfunction in experimental autoimmune encephalomyelitis reflects transient brain barrier breach and initiation of neuroinflammation in the olfactory bulb

Frontiers in Cellular Neuroscience
Olfactory dysfunction is increasingly recognized as an early, non-motor manifestation of multiple sclerosis (MS), but the mechanisms underlying its occurrence remain unclear.

Advances in the Management and Surgical Treatment of Intracranial Aneurysms [PDF]

, 1974
Patients who have sustained a spontaneous subarachnoid hemorrhage are victims of a very serious illness. Not only are they subject at all times to the potentially catastrophic results of a recurrent bleed, but they are faced with the manifestations of ...

Acute Invasive Pulmonary Aspergillosis With CNS Dissemination in an Immunocompetent Individual: A Case Report

Clinical Case Reports, Volume 14, Issue 4, April 2026.
ABSTRACT Invasive pulmonary aspergillosis can occur in patients without classical immunosuppression, particularly those with COPD and corticosteroid exposure. Early recognition, prompt antifungal therapy, and vigilance for neurological symptoms are essential to prevent central nervous system dissemination, which carries high mortality and significant ...

The Glymphatic System and Meningeal Lymphatics: Current Understandings and Future Perspectives

MedComm, Volume 7, Issue 4, April 2026.
Brain waste clearance relies on the anatomical and functional integration of the glymphatic system and meningeal lymphatic vessels. Cerebrospinal fluid influx into the brain parenchyma occurs along periarterial spaces, a process driven by polarized aquaporin‐4 (AQP4) water channels on astrocytic endfeet.

Insights on pathophysiology of hydrocephalus rats induced by kaolin injection

FASEB BioAdvances
Hydrocephalus can affect brain function and motor ability. Current treatments mostly involve invasive surgeries, with a high risk of postoperative infections and failure. A successful animal model plays a significant role in developing new treatments for

Cerebral Fat Migration After Spine Surgery

Journal of the Belgian Society of Radiology
A 73-year-old patient with a complex sacral fracture underwent stabilising orthopaedic surgery. Postoperative brain CT showed fat droplets in the subarachnoid space and lateral ventricle. These fat droplets migrated into the cerebrospinal fluid by a tear
