Incidental Findings of Appendiceal Diverticulitis Presenting as Acute Appendicitis.

Diverticulosis of the appendix (DA) is a rare pathological finding that clinically imitates acute appendicitis and is most commonly found in adult males with chronic abdominal pain. It has a higher rate of perforation compared to acute appendicitis (84% vs 12%, P<0.01), and is consequently associated with a higher rate of mortality.

Intraoperative and biomechanical studies of human vastus lateralis and vastus medialis sarcomere length operating range.

The vast majority of musculoskeletal models are not validated against primary experimental data. Conversely, most human experimental measurements are not explained theoretically using models to provide a mechanistic understanding of experimental results. Here we present a study with both primary human data and primary modeling data.
