Persistent MRI Findings Unique to Blast and Repetitive Mild TBI: Analysis of the CENC/LIMBIC Cohort Injury Characteristics.
Mil Med
August 2024
Department of Neurology, Traumatic Brain Injury and Concussion Center, University of Utah, Salt Lake City, UT 84132, USA.
Article Synopsis
- MRI is a key tool in researching diagnostic and prognostic markers after traumatic brain injury (TBI), particularly to understand mild TBI (mTBI), but findings are often inconsistent, highlighting the need for further study.
- The study analyzed MRI data from 976 military veterans and service members to explore the links between imaging outcomes and clinical features of mTBI, using regression models to account for factors like age and sex.
- Results indicated that while no major differences were found between those with and without mTBI history, blast-related mTBI showed significant brain volume reductions in certain areas, and multiple mTBIs correlated with specific MRI findings.
The π-interactions of ammonia ligands evaluated by ligand field theory.

Ammonia and amine ligands are commonly assumed to be σ-only ligands in coordination chemistry, they are not expected to interact significantly with a metal a π path. Ligand field analyses employing the Angular Overlap Model resulted in good fits to experimental data without a π parameter for ammonia ligands, thereby supporting this assumption. In this work, we challenge this assumption and suggest that it is an oversimplification.

Significance: Diffuse correlation spectroscopy (DCS) is an emerging optical modality for non-invasive assessment of an index of regional cerebral blood flow. By the nature of this noninvasive measurement, light must pass through extracerebral layers (i.e.

July 2023
Department of Dermatology, Venereology and Leprology, Postgraduate Institute of Medical Education and Research, Chandigarh, 160012, India.
Article Synopsis
- Leprosy has traditionally been categorized into specific types, but this classification overlooks many unusual clinical forms that can complicate diagnosis.
- The study aims to showcase eight uncommon presentations of leprosy observed over a decade, highlighting rare forms such as psoriasiform plaques and Lazarine leprosy.
- The findings emphasize the importance of recognizing these atypical presentations to ensure accurate diagnosis and timely treatment, ultimately preventing severe complications from this treatable disease.
