Article Synopsis
- Researchers are studying the multi-scale interstellar medium (ISM) of our Galaxy to understand the relationships between gas, dust, and star formation in Giant Molecular Clouds (GMCs).
- The Milky Way's complex structure is influenced by massive stars and dust lanes, making it essential to observe these features at (sub-)millimeter wavelengths for in-depth analysis.
- A proposed 50m single-dish sub-mm telescope called AtLAST aims to provide comprehensive observations of the Galactic Plane and surrounding areas to enhance our understanding of stellar formation, planetary system evolution, and the overall ecology of our Galaxy.
Article Synopsis
- MRI is effective at identifying bone marrow involvement in multiple myeloma but struggles with detecting bone lesions, prompting a study to test new MRI techniques (ZTE and BB) against whole-body CT as a reference.
- The study included 47 patients diagnosed with multiple myeloma or at high risk, assessing the performance of ZTE and BB MRI sequences alongside PET/CT scans for detecting osteolytic lesions.
- Results showed that experienced radiologists achieved high accuracy (98%) with both MRI techniques, but there were noticeable discrepancies in detection rates across different regions, particularly with an increased false-negative rate in the spine when using ZTE.
The locus coeruleus-norepinephrine system is thought to be involved in the clinical effects of vagus nerve stimulation. This system is known to prevent seizure development and induce long-term plastic changes, particularly with the release of norepinephrine in the hippocampus. However, the requisites to become responder to the therapy and the mechanisms of action are still under investigation.

Whole-body MRI (WB-MRI) has been introduced among diagnostic methods for the staging and follow-up assessment in oncologic patients, and international guidelines recommend its use. In nononcologic applications, WB-MRI is as a promising imaging tool in inflammatory diseases, such as seronegative arthritis and inflammatory myopathies.

Offering HIV screening to key populations in emergency departments (EDs) is a strategy that has been demonstrated to be effective. Analyzing patient and provider perceptions of such screening can help identify implementation facilitators and barriers.
