PURPOSE To compare the biomechanical properties of porcine, rabbit, and human sclera before and after riboflavin/ultraviolet-A (UVA) collagen cross-linking (CXL). METHODS Eight rabbits, 8 porcine eyeballs, and 8 human eyeballs were included. One rabbit eye and half of each bisected human and porcine eyeball were treated with riboflavin/UVA CXL. Untreated fellow rabbit eyes and eyeball halves ...
Morphological responses of nonmammalian herbivores to external ecological drivers have not been quantified over extended timescales. Herbivorous nonavian dinosaurs are an ideal group to test for such responses, because they dominated terrestrial ecosystems for more than 155 Myr and included the largest herbivores that ever existed. The radiation of dinosaurs was punctuated by several ecological...
Biomechanical Energy Harvesters In article number 2204304, William W. Yu, Wen Jung Li, Walid A. Daoud, and co-workers demonstrate a high-performance flexible biomechanical energy harvester by switching its interfacial adhesion via hydrogen bonding interactions solvent evaporation induced phase separation. This wearable power source can generate record high peak density of 20.5 W m−2 Hz−1 under ...
Introduction: Nowadays, observational methods based on video recording of work processes and its analysis by using computers software are widely used. Therefore, the aim of this study is the assessment of welder’s posture and its biomechanical analysis by using CATIA software. Methods: This research has been done on welders Iranian Gas Transmission Company. Evaluated postures, which incl...
Objective: The aim of this study was to investigate the effect of eight weeks of high intensive exercise on selected biomechanical and anthropometrical variables in elite wrestlers. Methods: Sixteen young wrestlers (age 19.1±1 years and weight 74.9±17.3 kg) attending the national Greco-Roman camps participated in this study. Biomechanical and anthropometrical variables included...
Objective: The main aim of the study was comparing the main anthropometric and biomechanics indexes in elite male adult Wushu athletes in both Taolu and Sanda disciplines. Methods: The sample of the present study included 20 elite male Wushu athletes who were checked for 33 anthropometric and 11 biomechanical indexes. The normality of the data was checked by Kolmogorov–Smirnov no...
Objective- To evaluate greater omentum as an autogenous free graft in enhancing bone healing.Design- Prospective descriptive trial.Animals- Ten mongrel adult dogs, 3 to 4 years old and weighing 25.2 to 31 kg, assigned into two equal experimental and control groups (5dogs/group), were used.Procedures- Mid-shaft osteotomy on right radius was followed by a partial omentectomy in all dogs. A 30x30 ...
Many of the venous functions are biomechanical in their nature and/or related closely to biomechanical (hemodynamic) forces: 1 Blood conduits, collectors with flow-rectifying valves 2. Maintenance of filling pressure for the right heart by controlling venous return in the face of widely varying cardiac output arterial pressure buffer 3. Capacity function, redistribution of blood volume 4. Postc...
Biomechanical tests are widely used in animal studies on osteoporotic fracture healing. However, the biomechanical recovery process is still unknown, leading to difficulty in choosing time points for biomechanical tests and in correctly assessing osteoporotic fracture healing. To determine the biomechanical recovery process during osteoporotic fracture healing, studies on osteoporotic femur fra...
The zona pellucida (ZP) is an extracellular membrane surrounding mammalian oocytes. The so-called zona hardening plays a key role in fertilization process, as it blocks polyspermy, which may also be caused by an increase in the mechanical stiffness of the ZP membrane. However, structural reorganization mechanisms leading to ZP's biomechanical hardening are not fully understood yet. Furthermore,...
