Best waveform score for diagnosing keratoconus

Revista Brasileira de Oftalmologia, 2013
PURPOSE: To test whether corneal hysteresis (CH) and corneal resistance factor (CRF) can discriminate between keratoconus and normal eyes and to evaluate whether the averages of two consecutive measurements perform differently from the one with the best ...

The crucial role of meshing in computational fluid dynamics simulations for organic geometries in paleobiology: Describing fluid dynamics performance through best practices

Methods in Ecology and Evolution, Volume 16, Issue 10, Page 2170-2194, October 2025.
Abstract Computational fluid dynamics (CFD) has become an essential tool for studying fluid interactions in biological systems. While widely used in engineering, its application in the natural sciences, particularly in paleobiology, remains limited due to the challenges of meshing complex organic geometries.

Shearing Tooth Morphology May Allow Sharks to Access Higher Trophic Levels at Smaller Sizes

Ecology and Evolution, Volume 15, Issue 8, August 2025.
Predator morphology imposes limitations on prey selection due to biomechanical constraints, making some prey functionally inaccessible and thereby constraining predator trophic niches. We assessed how two key components of trophic morphology—tooth shape and body size—affect prey selectivity and trophic niche in two sympatric sharks with contrasting ...

Minimally Invasive Glaucoma Surgery Procedure in the Human Eye. A Fluid Structure Interaction Study

International Journal for Numerical Methods in Biomedical Engineering, Volume 41, Issue 7, July 2025.
The implantation of a microstent for glaucoma surgery has been successfully simulated for the first time. A Fluid‐Structure Interaction (FSI) simulation is introduced to model aqueous humor flow dynamics post‐surgery, enabling a detailed analysis of the microstent's interaction with ocular tissues and fluids.

Gender‐Based Differences in the Biomechanical Behavior of the Thorax During CPR Maneuvers

International Journal for Numerical Methods in Biomedical Engineering, Volume 40, Issue 12, December 2024.
Cardiopulmonary resuscitation (CPR) is a common emergency procedure for cardiac arrest. This study presents numerical experiments simulating this maneuver in both genders to determine the optimal location and force for chest compressions. By analyzing deformation and stress, this investigation demonstrates that the ideal compression point is lower on ...

An overview of the risk factors for producing fifth metatarsal fracture in sports activities: A systematic review

Journal of Foot and Ankle Research, Volume 17, Issue 4, December 2024.
Abstract Introduction The fifth metatarsal fracture is a foot injury that occurs in sports activities. This fracture has been associated with risk factors based on intrinsic variables such as type of feet (flatfoot or cavus foot), foot pathologies, and bone density among others.
