Strategic Use of Ad Hoc Commissions for Blame Avoidance: Evidence From Chile

Public Administration Review, EarlyView.
ABSTRACT Ad hoc commissions are well known in policymaking, yet their strategic deployment during crises remains less understood. This study examines how governments rely on expert commissions to manage blame and political risk in response to critical events.

Confined spaces in space: Cerebral implications of chronic elevations of inspired carbon dioxide and implications for long‐duration space travel

Experimental Physiology, EarlyView.
Abstract Cerebrovascular regulation is critically dependent upon the arterial partial pressure of carbon dioxide (PaCO2${P_{{\mathrm{aC}}{{\mathrm{O}}_{\mathrm{2}}}}}$), owing to its effect on cerebral blood flow, tissue PCO2${P_{{\mathrm{C}}{{\mathrm{O}}_{\mathrm{2}}}}}$, tissue proton concentration, cerebral metabolism and cognitive and neuronal ...

Physiological cerebrospinal fluid interactions between brain and eye structures are altered after long‐duration spaceflight

Experimental Physiology, EarlyView.
Abstract Long‐duration spaceflight represents an extreme challenge, triggering adaptive responses including spaceflight‐associated neuro‐ocular syndrome, characterized by diminished visual acuity and ocular changes, which is a significant health risk for Mars missions.

Sex differences in the prefrontal cortex and muscle oxygenation during exercise until exhaustion in endurance‐trained individuals

Experimental Physiology, EarlyView.
Abstract figure legend During cardiopulmonary exercise testing, the decline in oxygenation in the prefrontal cortex of women is striking. This crucial brain area is directly involved in planning motor tasks. The decline is particularly pronounced at higher exercise intensities, especially after reaching the respiratory compensation point or anaerobic ...

Prenatal air pollution exposure is associated with altered neurodevelopmental outcomes in early childhood

The Journal of Physiology, EarlyView.
Abstract figure legend This study examined the effect of modelled maternal air pollution exposure during gestation on neurodevelopment in a community cohort of 498 toddlers recruited from Greater London, UK. Higher 1st trimester exposure to particulate matter and nitrogen dioxide was associated with lower language scores at 18 months adjusting for ...

T2‐Weighted T1 Mapping and Automated Segmentation of CSF: Assessment of Solute Gradients in the Healthy Brain

Journal of Magnetic Resonance Imaging, Volume 64, Issue 1, Page 218-227, July 2026.
ABSTRACT Background Cerebrospinal fluid (CSF) serves as a medium for nutrient delivery and waste clearance. The T1 relaxation rate, R1, can be used to measure the concentration of intrinsic solutes and extrinsic contrast agents. Purpose To implement a method for R1 mapping and segmentation of CSF and to use this method to explore how R1 of CSF relates ...

In utero ventriculosubgaleal shunt placement in a fetal lamb model: Phase 1 technical insights

Pregnancy, Volume 2, Issue 4, July 2026.
Abstract Background Progressive ventriculomegaly and the resulting irreversible brain damage may be mitigated through timely diversion prenatal intervention. While ventriculosubgaleal shunt (VSGS) is commonly performed postnatally in premature infants, in utero placement is unexplored.

Cone beam computed tomographic myelography in horses with cervical vertebral compressive myelopathy

Equine Veterinary Journal, Volume 58, Issue 4, Page 1049-1060, July 2026.
Abstract Background While computed tomographic (CT) myelography is increasingly available and has been evaluated in alive horses, objective criteria for diagnosing cervical vertebral compressive myelopathy (CVCM) are lacking. Objectives To establish morphometric dimensions of the cervical vertebral canal and spinal cords from horses with CVCM and ...
