Introduction This study aimed to quantitatively investigate the role of marginal chordae of the mitral valve during static closure by analyzing the force within these chordae and its potential correlation with the transvalvular pressure. Materials and Methods Porcine (n = 10) and human (n = 4) mitral valves were mounted in a saddle-shaped annulus clamp, while an in vitro system was utilized to replicate a physiological systoli...

Sit-to-stand (STS) is a fundamental activity of daily living that is essential for independent living but remains difficult for many older adults, including those with knee osteoarthritis (KOA), even after a total knee arthroplasty (TKA). Investigating age- and disease-related changes in STS kinematics and muscle function is key for understanding whether there are kinematic changes that limit how patients’ muscles are used to...

Large blooms of the diazotrophic cyanobacteria, Trichodesmium , have been reported along the north coast of Australia and are readily evident in remote sensing images. During a research cruise in November 1999, we sampled from Townsville to Broome, examined Trichodesmium population densities and their rates of carbon and N 2 fixation alongside microscopy-based cell counts of them and other cyanobacterial diazotrophs. Additiona...
