Experimental Measurement and Mathematical Quantification of Fixed-Charged Density in Rat and Pig Brain Tissue.

Cerebral edema is associated with poor prognosis because brain swelling within the rigid skull raises intracranial pressure, exacerbating secondary injuries following traumatic brain injury. Brain swelling can be characterized by triphasic biomechanics, which models brain tissue as a mixture of a deformable porous solid matrix with a negative fixed-charged density (FCD), water, and monovalent counterions. When brain cells die, the intracellular FCD is exposed, attracting cations into the cells.

School food policy in secondary schools in England and its impact on adolescents' diets and dental health: the FUEL multiple-methods study.

Background: School food standards are a legal requirement for state-funded schools in England and are designed to promote healthy eating in pupils. However, state-funded academies/free schools established between 2010 and 2014 are exempt from this legislation. To complement the school food standards, the government launched the School Food Plan in 2013, which outlines voluntary actions that schools can take to support healthy eating and increase school meal uptake.

Low-Dose Naltrexone Use in Biopsy-Proven Lichen Planus of the Nails.

Importance: Nail lichen planus has the potential to cause permanent destruction of the nail unit and remains challenging to treat. Studies suggest that low-dose naltrexone is a safe and potentially effective treatment for other dermatologic conditions, including lichen planopilaris.

Objective: To assess the effectiveness of low-dose naltrexone in treating nail lichen planus.

National school food standards in England: a cross-sectional study to explore compliance in secondary schools and impact on pupil nutritional intake.

Background: Many countries have introduced school food standards to improve the dietary intakes of school-aged children. England has school food standards (SFS) legislation in place but little is known about how well secondary schools comply with this. We aimed to assess compliance with the SFS legislation in English secondary schools and explore the impact of the SFS on pupils' nutritional intake.
