Light-sheet fluorescence microscopy (LSFM), a prominent fluorescence microscopy technique, offers enhanced temporal resolution for imaging biological samples in four dimensions (4D; x, y, z, time). Some of the most recent implementations, including inverted selective plane illumination microscopy (iSPIM) and lattice light-sheet microscopy (LLSM), move the sample substrate at an oblique angle relative to the detection objective's optical axis. Data from such tilted-sample-scan LSFMs require subsequent deskewing and rotation for proper visualisation and analysis.

Tendons play fundamental roles in the execution of human movement and therefore understanding tendon function, health and disease is important for everyday living and sports performance. The acute mechanical behavioural and physiological responses to short-term loading of tendons, as well as more chronic morphological and mechanical adaptations to longer term loading, differ between sexes. This has led some researchers to speculate that there may be a sex-specific injury risk in tendons.

The Saudi Commission for Health Specialties (SCFHS), the regulatory agency for health professions in the Kingdom of Saudi Arabia (KSA), sought to evolve the continuing professional development (CPD) ecosystem for the country and to promote the concept of life-long learning for healthcare professionals. SCFHS audited its own CPD accreditation system, reviewed internationally recognised CPD accreditation criteria, adopted a new set of standards, and trained its staff and provider community in their adoption. SCFHS also deployed a range of programmes and grants to support healthcare educators and researchers engaged in CPD.

Article Synopsis
  • An accelerated diagnostic pathway was implemented for low-risk emergency room patients with chest pain, focusing on early outpatient cardiac CT versus inpatient angiography.
  • A cohort study tracked patient outcomes and decision-making factors over a year, finding no mortality or myocardial infarction 30 days post-discharge for those undergoing outpatient cardiac CT.
  • Results showed that most patients had low calcium scores, and factors like age and troponin levels influenced the choice between CT and invasive angiography, with minimal need for revascularization.

Light-sheet fluorescence microscopy (LSFM), a prominent fluorescence microscopy technique, offers enhanced temporal resolution for imaging biological samples in four dimensions (4D; x, y, z, time). Some of the most recent implementations, including inverted selective plane illumination microscopy (iSPIM) and lattice light-sheet microscopy (LLSM), rely on a tilting of the sample plane with respect to the light sheet of 30-45 degrees to ease sample preparation. Data from such tilted-sample-plane LSFMs require subsequent deskewing and rotation for proper visualization and analysis.

Resistance training at longer muscle lengths induces greater muscle hypertrophy and different neuromuscular functional adaptations than training at shorter muscle lengths. However, the acute time course of recovery of neuromuscular characteristics after resistance exercise at shorter and longer muscle lengths in the quadriceps has never been described. Eight healthy young participants (4 M, 4 F) were randomly assigned to perform four sets of eight maximal isometric contractions at shorter (SL; 50° knee flexion) or longer (LL; 90° knee flexion) muscle lengths in a crossover fashion.
