Platelet-rich plasma： combinational treatment modalities for musculoskeletal conditions

引用

Frontiers of Medicine 2018年第2期12卷 139-152页

作者： Isabel Andia michele Abate Regenerative Medicine Laboratory RioCruces Health Research Institute Cruces University Hospital 48903 Barakaldo Spain Department of Medicine and Science of Aging University G. d'Annunzio Chieti-Pescara 66013 Chieti Scalo Italy

Current research on common musculoskeletal problems, including osteoart]cular cona]t]ons, tendinopathies, and muscle injuries, focuses on regenerative translational medicine. Platelet-rich plasma therapies have emerged as a potential approach to enhance tissue repair and regeneration. Platelet-rich plasma application aims to provide supraphysiological concentrations of platelets and optionally leukocytes at injured/pathological tissues mimicking the initial stages of healing. However, the efficacy of platelet-rich plasma is controversial in chronic diseases because patients＇ outcomes show partial improvements. Platelet-rich plasma can be customized to specific conditions by selecting the most appropriate formulation and timing for application or by combining platelet-rich plasma with synergistic or complementary treatments. To achieve this goal, researchers should identify and enhance the main mechanisms of healing. In this review, the interactions between platelet-rich plasma and healing mechanisms were addressed and research opportunities for customized treatment modalities were outlined. The development of combinational platelet-rieh plasma treatments that can be used safely and effectively to manipulate healing mechanisms would be valuable and would provide insights into the processes involved in physiological healing and pathological failure.

Scour process caused by multiple subvertical non-crossing jets

引用

Water Science and Engineering 2017年第1期10卷 17-24页

作者： Stefano Pagliara michele Palermo DESTEC-Department of Energy SystemsTerritory and Construction EngineeringUniversity of Pisa56122 PisaItaly

The scour process induced by plunging jets is an important topic for hydraulic engineers. In recent decades, several researchers have developed new strategies and methodologies to control the scour morphology, including different jet arrangements and structures located in the stilling basin. It has been found that multiple jets can cause less scouring than single plunging jets. Based on this evidence, this study aimed to investigate the equilibrium morphology caused by multiple non-crossing jets. A dedicated laboratory model was built and experimental tests were carried out under different combinations of jet inclination angles, by varying the tailwater level and the virtual crossing point location, which was set below the original channel bed level. It was experimentally shown that the equilibrium scour morphology depends on the jet discharge, the differences in non-crossing jet inclination angles, the downstream water level, and the distance of the virtual crossing point from the original channel bed level. In particular, the last parameter was found to be one of the most influential parameters, because of the resulting flow patterns inside the water body. Furthermore, the analysis of experimental evidence allowed for a complete and detailed classification of the scour hole typologies. Three different scour typologies were distinguished and classified. Finally, based on previous studies, two novel re-lationships have been proposed to predict both the maximum scour depth and length within a large range of hydraulic and geometric parameters.
