Two Central Nervous System Tumors in One Catheter Lab: Time to Rethink Radiation Protection

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Very little research has been done on the possible effects that repeated, frequent, and low‐dose ionizing radiation exposure has on the long‐term health of interventional cardiologists. Aims Following the diagnosis in the same year of two central nervous system tumors in two operators working in the same catheter laboratory, we ...

Fish Scales: A Multifunctional Biomaterial from Nature

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Fish scales demonstrate nature's solution to impact protection through overlapping multilayered architecture. This biological design combines mineralized surfaces with collagen networks to achieve both flexibility and fracture resistance. The structural principles inspire advanced protective materials and biomedical implants, where damage tolerance ...

Contact Lens Knowledge and Practices Among Students in the College of Health Sciences, University of Ghana: A Cross‐Sectional Study

open access: yesEye &ENT Research, EarlyView.
ABSTRACT Background Contact lenses (CLs) are increasingly used worldwide for refractive error correction because of their optical, cosmetic, and functional advantages over spectacles. However, although their safe and effective use depends on adequate knowledge and proper hygiene practices, there is limited evidence on contact lens‐related knowledge ...

Ranking of antiseizure medications in a panel of focal seizure models predicts their comparative efficacy in clinical add‐on trials in drug‐resistant focal epilepsy

open access: yesEpilepsia, EarlyView.
Abstract Objective Most antiseizure medications (ASMs) have been discovered by testing in animal models, which are generally thought to predict antiseizure activity in patients. However, it is not known whether any of these models (or a combination of models) can predict whether a novel ASM exhibits higher clinical efficacy in focal drug‐resistant ...

Intestinal microbiome alterations in pediatric epilepsy: Implications for seizures and therapeutic approaches

open access: yesEpilepsia Open, EarlyView.
Abstract The intestinal microbiome plays a pivotal role in maintaining host health through its involvement in gastrointestinal, immune, and central nervous system (CNS) functions. Recent evidence underscores the bidirectional communication between the microbiota, the gut, and the brain and the impact of this axis on neurological diseases, including ...

Leptin Reduces Running in a Rodent Anorexia Nervosa Model via a Distributed Neural Network

open access: yesEuropean Eating Disorders Review, EarlyView.
ABSTRACT Objective Hyperactivity is a persistent and clinically relevant symptom in anorexia nervosa (AN). Hyperactivity is inversely correlated with leptin levels. While systemic leptin administration attenuates hyperactivity in rodent models, the specific brain regions mediating this effect remain unclear.
