Effect of bar jump height on kinetics and kinematics of take-off in agility dogs.
PLoS One

Faculty of Veterinary Medicine, Department of Equine and Small Animal Medicine, University of Helsinki, Helsinki, Finland.
Sport-related injuries have been reported to occur in around one-third of agility dogs. Higher bar height in competitions has been shown to increase odds of an injury. This study evaluated the effect of bar height on the kinetics and kinematics at take-off to a bar jump.

PLoS One
January 2025
Faculty of Education and Arts, Sohar University, Sohar, Oman.
Conjugate Gradient (CG) methods are widely used for solving large-scale nonlinear systems of equations arising in various real-life applications due to their efficiency in employing vector operations. However, the global convergence analysis of CG methods remains a significant challenge. In response, this study proposes scaled versions of CG parameters based on the renowned Barzilai-Borwein approach for solving convex-constrained monotone nonlinear equations.

PLoS One

Department of Biomedical and Robotics Engineering, Incheon National University, Incheon, Korea.
Gait disturbance is one of the most common symptoms in patients with Parkinson's disease (PD) that is closely associated with poor clinical outcomes. Recently, video-based human pose estimation (HPE) technology has attracted attention as a cheaper and simpler method for performing gait analysis than marker-based 3D motion capture systems. However, it remains unclear whether video-based HPE is a feasible method for measuring temporospatial and kinematic gait parameters in patients with PD and how this function varies with camera position.

J Cell Physiol
January 2025
Department of Spine, Wangjing Hospital of China Academy of Chinese Medical Sciences, Beijing, China.
In this study, we explored the impact of different biomechanical loadings on lumbar spine motion segments, particularly concerning intervertebral disc degeneration (IVDD). We aimed to uncover the cellular milieu and mechanisms driving ossification in the nucleus pulposus (NP) during IVDD, a process whose underlying mechanisms have remained elusive. The study involved the examination of fresh NP tissue from the L3-S1 segment of five individuals, either with IVDD or healthy.
