Three-dimensional joint kinematics during canine locomotion are commonly measured using skin marker-based stereophotogrammetry technologies. However, marker-related errors caused by the displacement of surface relative to underlying bones (i.e., soft tissue artifacts, STA) may affect accuracy measurements and obscure clinically relevant information. Few studies have assessed STA in limbs kinematic analysis. The magnitudes patterns their influence on analysis remain unclear. Therefore,...

An anthocyanin-graphene hybrid heterojunction has been designed as a highly pH-value sensitive and self-powered photodetector.

As a result of the inexorable development economy and ever-increasing population, demand for water in urban rural sectors has increased, this turn caused quality eutrophication reservoir to become legitimate concern environment management river basins. Phosphorus (P) is one limiting nutrients aquatic ecosystems; P sediment primary factor eutrophication. Yuecheng Reservoir located most productive intensively cultivated agricultural regions North China. Detailed knowledge lacking at regional...

The aim of this study was to determine the differences in surface contour between models native pelvic bones and their corresponding three-dimensional (3D)-printed replicas.Digital 3D five cadaveric hemipelves live dogs with contralateral fractures were generated based on computed tomographic images printed. 3D-printed replicas underwent scanning digital created. model each replica superimposed onto hemipelvis. Errors determined by comparing distances 120,000 points models. medial surface,...

Upconversion nanoparticles are popular as imaging probes due to their advantages in photostability and controllable emission dimensions. However, upconversion polarization remains largely uncharted with previous reports limited microstructures. In this work, we report the observation of polarized emissions from β-NaYF4 single nanostructures below 100 nm. At sub-100 nm scale, nanorods, nanodiscs, nanoplates exhibit distinctive degrees despite same doping concentrations lanthanides. We find...

Skin marker‐based motion analysis has been widely used to evaluate the functional performance of canine gait and posture. However, interference soft tissues between markers underlying bones (soft tissue artefacts, STAs) may lead errors in kinematics measurements. Currently, no optimal marker attachment sites cluster compositions are recommended for analysis. The current study aims cluster‐level STAs effects on computed stifle kinematics. Ten mixed‐breed healthy dogs affixed with 19...

The study aimed to perform isometry analysis of a selection suture attachment points for extracapsular stabilization with three-dimensional (3D) measurements and normal gait kinematics the stifle joint.Thirteen client-owned dogs were recruited. Fluoroscopic images during treadmill walking computed tomography same joint acquired. Stifle reconstructed using 3D model-based fluoroscopic analysis. Variability distance between femoral tibial sites across cycles was evaluated. maximum length...

Introduction: Meniscal tissue engineering serves as a potential alternative to current treatments for canine meniscal injury. To date, tissue-engineered implants are not available, likely due the failure of in vitro application optimal biomechanical stimulation appropriate stage neotissue formation. The objective this study was observe cell-seeded hydrogels exercised simple knee-like bioreactor, tested pilot study.

Due to the rapid exploitation of water resources in Huixian karst wetland southwest China past decades, has suffered from shrinkage size and serious degradation ecological functioning. To assess how much within could still be taken out for local supply purposes while can kept its normal Through use multi-methods, including field surveys by a multi-disciplinary team, balance, Remote Sensing, GIS numerical simulation, this paper characterizes regime study area finally determines scenarios...

For example—Cixian Fuyang River Regulation Project. Due to the character that is located in hilly areas of Cixian, we use Hex-ras software calculate status river water surface line for goal determining final treatment plan. We maintain present situation channel design as principle, select most appropriate pushed level and roughnessas basic, combine classification calculation crossing structures backwater encryption section get more accurate result. compare elevation cross strait, analyze...

Abstract Affected by human activities and natural factors, the area of Huixian karst wetland has been shrinking in recent years. As main data source, Landsat5 TM remote sensing image was used to analyze trend landforms its driving factors. The changes various types sensitivity water influencing factors past 30 years were analyzed visual interpretation, supervised classification geographic information system. analysis results show that decreased significantly years, reduction is 4.52 km 2...

Introduction: Meniscal injuries are a common cause of pain and disability in dogs. Tissue engineering approaches provide alternatives to current treatments. In our previous study, we arthroscopically harvested synoviocytes from clinical canine patients. Using chondrogenic growth factor protocols, anatomically sized synoviocyte neotissues formed, but ECM composition was sub-optimal. vivo, the meniscus is under constant load, role mechanical stimulation should not be overlooked. Our strategy...
