Researchers discovered a novel Fe-N-C protective layer that enhances the stability of platinum-based fuel cell catalysts. The 'core-shell' design shields platinum from corrosion and creates a powerful electronic interaction at the interface.
A new machine-learning model uses pre-therapy PET/CT scans to estimate radiation dose to tumors and healthy organs, improving patient selection and reducing toxicity risk. The study's findings suggest a promising ability to predict post-therapy dosimetry, which may optimize treatment plans for individual patients.
A population-based screening trial evaluating a cell-free DNA multicancer early detection test found modest increases in diagnostic delay rates for head and neck, lung, and upper gastrointestinal cancers. These findings suggest that future trials may need to consider system-level spillover effects on healthcare resources.
A recent immigration ban could reduce the US physician and nurse workforce, exacerbating health care workforce shortages in already underserved communities. The study found nearly 24,000 physicians and 56,000 nurses from banned countries contributed to the US healthcare workforce in 2023.
The Society of Nuclear Medicine and Molecular Imaging recognized six new Fellows for their exceptional contributions to the field. The SNMMI Fellowship honors members who have demonstrated excellence in scientific discovery, educational efforts, or clinical practice.
This study found that Justicia carnea ethanol extracts effectively reduced oxidative stress markers, inflammation, and lipid peroxidation in a mouse model of chronic pancreatitis. The extracts also preserved islet glucagon expression, indicating potential therapeutic benefits for pancreatic damage.
This AAV platform integrates MGS4 peptide-guided capsid targeting, hypoxia-responsive elements, and dual shRNA vectors to selectively deliver chemokines and PNAi to NSCLC tumors. The combination of these elements aims to enhance antitumor immunity while suppressing tumor invasiveness.
A multicenter clinical trial found that implanting collagen tiles during brain surgery improved tumor control and lowered the risk of recurrence by 12.1% compared to current standard of care. Patients treated with tile-based radiation therapy (TBRT) had a median overall survival of 42.5 months, more than double the 17.6 months seen wit...
Vasken Dilsizian, MD, has received the Minoshima-Pappas Transformational Leadership Award for his vision and leadership in advancing nuclear medicine and molecular imaging. He has made significant contributions to the field of cardiovascular diseases through his innovative scientific work.
Scientists have identified dopamine as a key player in mediating stress-induced courtship suppression in male Drosophila fruit flies. The duration of stress exposure significantly influenced the persistence of suppressed courtship behavior, highlighting the importance of dopamine signaling in this process.
