Article Synopsis
- * Researchers assessed 88 ALS patients for hexanucleotide repeat expansion in the C9orf72 gene and other known ALS-linked genes using next-generation sequencing.
- * Results showed 13.5% had pathogenic HRE in C9orf72, and unexpected findings included no pathogenic variants in young-onset sporadic patients, suggesting potential genetic variability that remains unexplored.
Glenohumeral (GH) biomechanics after rotator cuff (RC) tears are not fully understood. The purpose of our study was to determine if the critical shoulder angle (CSA), type of RC tears, and level of weight bearing increase GH translation, instability based on the instability ratio, muscle forces and joint reaction force (JRF), and shifts the center of force (CoF) superiorly. A GH simulator with muscle-mimicking cable systems was used to simulate 30° abduction in the scapular plane.

- - Gastrointestinal lymphoma is the most prevalent lymphoma in cats, with aggressive forms being rare and having a poor prognosis; due to sampling challenges, immunophenotyping isn't typically performed.
- - A study involving 32 cats diagnosed and categorized their gastrointestinal lymphomas using flow cytometry immunophenotyping, linking it to the WHO classification and clonality testing.
- - The study found high agreement between histopathology and flow cytometry, with 87.5% of cases showing consistency and positive clonality results in 87.5% of the patients, marking a significant advancement in lymphoma subtype identification.
Article Synopsis
- The study examined how rotator cuff tears affect shoulder movement during a 30° abduction test using fluoroscopy, involving 75 participants divided into three groups: younger controls, older controls, and patients with rotator cuff tears.
- Participants performed arm movements with varying weights, and researchers measured scapular rotation and glenohumeral translation.
- Findings revealed greater scapular rotation in those with rotator cuff issues compared to healthy shoulders, with increased load affecting scapular rotation dynamics but only influencing glenohumeral translation in those with rotator cuff tendinopathy.
Glenohumeral biomechanics after rotator cuff (RC) tears have not been fully elucidated. This study aimed to investigate the muscle compensatory mechanism in weight-bearing shoulders with RC tears and asses the induced pathomechanics (i.e.
