Previous studies have confirmed that intervertebral disc degeneration(IDD)is closely associated with inflammation-induced reactive oxygen species(ROS)and resultant cell mitochondrial membrane potential(MMP)decline.Clearance of ROS in an inflammatory environment is essential for breaking the vicious cycle of MMP decline.Additionally,re-energizing the mitochondria damaged in the inflammatory milieu to restore their function,is equally important.Herein,we proposed an interesting concept of mitochondrion-engine equipped with coolant,which enables first to“cool-down”the inflammatory environment,next to restore the MMP,finally to allow cells to regain normal energy metabolism through materials design.As such,we developed a multifunctional composite composed of a reactive oxygen species(ROS)-responsive sodium alginate/gelatin hydrogel infused into a rigid 3D-printed thermoplastic polyurethane(TPU)scaffold.The TPU scaffold was coated with conductive polypyrrole(PPy)to electrophoretically deposit L-arginine,which could upregulate the Mammalian target of rapamycin(mTOR)pathway,thus increasing MMP and energy metabolism to stimulate extracellular matrix synthesis for IVD repair.While the ROS-responsive hydrogel acting as the“mito-engine coolant”could scavenge the excessive ROS to create a favorable environment for IVD cells recovery.Demonstrated by in vitro and in vivo evaluations,the mito-engine system markedly promoted the proliferation and collagen synthesis of nucleus pulposus cells while enhancing the mitochondrial respiration and MMP under oxidative stress.Radiological and histological assessments in vivo revealed the efficacy of this system in IVD repair.This unique bioinspired design integrated biomaterial science with mitochondrial biology,presents a promising paradigm for IDD treatment. 展开更多

Filter bank multicarrier(FBMC)systems with offset quadrature amplitude modulation(OQAM)need long data blocks to achieve high spectral efficiency.However,the transmission of long data blocks in underwater acoustic(UWA)communication systems often encounters the challenge of time-varying channels.This paper proposes a time-varying channel tracking method for short-range high-rate UWA FBMC-OQAM communication applications.First,a known preamble is used to initialize the channel estimation at the initial time of the signal block.Next,the estimated channel is applied to detect data symbols at several symbol periods.The detected data symbols are then reused as new pilots to estimate the next time channel.In the above steps,the unified transmission matrix model is extended to describe the time-varying channel input-output model in this paper and is used for symbol detection.Simulation results show that the channel tracking error can be reduced to less than−20 dB when the channel temporal coherence coefficient exceeds 0.75 within one block period of FBMC-OQAM signals.Compared with conventional known-pilot-based methods,the proposed method needs lower system overhead while exhibiting similar time-varying channel tracking performance.The sea trial results further proved the practicability of the proposed method. 展开更多

When a pipe is partially filled with a given working liquid,the relationship between the electromotive force(EMF)measured by the sensor(flowmeter)and the average velocity is nonlinear and non-monotonic.This relationship varies with the inclination of the pipe,the fluid density,the pipe wall friction coefficient,and other factors.Therefore,existing measurement methods cannot meet the accuracy requirements of many industrial applications.In this study,a new processing method is proposed by which the flow rate can be measured with an ordinary electromagnetic flowmeter even if the pipe is only partially filled.First,a B-spline curve fitting method is applied to a limited set of measurements.Second,matrix inversion required in the B-spline curve method is optimized in order to reduce the number of needed computations.Dedicated experimental tests prove that the proposed method can effectively measure the average flow velocity of the fluid.When the fluid level of the pipeline is between 50%and 100%,the relative error is less than 3.5%. 展开更多

In this study,a novel artificial intervertebral disc implant with modified“Bucklicrystal”structure was designed and 3D printed using thermoplastic polyurethane.The new implant has a unique auxetic structure with building blocks joined“face-to-face”.The accompanied negative Poisson’s ratio enables its excellent energy absorption and stability under compression.The deformation and load distribution behavior of the implant under various loading conditions(bending,torsion,extension and flexion)has been thoroughly evaluated through finite element method.Results show that,compared to natural intervertebral disc and conventional 3D implant,our new implant exhibits more effective stress transfer and attenuation under practical loading conditions.The implant’s ability to contract laterally under compression can be potentially used to alleviate the symptoms of lumbar disc herniation.Finally,the biocompatibility of the implant was assessed in vitro and its ability to restore the physiological function of the disc segment was validated in vivo using an animal model. 展开更多

Objective Previous studies have shown that ex utero intrapartum therapy(EXIT)is safe and feasible for newborns with congenital diaphragmatic hernia(CDH).This study reports our experience with EXIT in fetuses with CDH in an attempt to explore the efficacy of EXIT on the survival rate of this population.Methods A retrospective analysis of the clinical data of 116 children with CDH was conducted.The children were assigned to EXIT and non-EXIT groups.Propensity score matching(PSM)toward clinical data was performed,and the clinical characteristics and outcomes were compared.Taking survival at discharge as the main outcome,logistic regression analysis was carried out to explore the efficacy of EXIT on survival.Results During the study period,30 of 116 children received EXIT.After PSM,the survival rates of the EXIT group and the non-EXIT group were 82.76%(24/29)and 48.28%(14/29),respectively(p=0.006).EXIT(OR=0.083,95%CI=0.013to 0.525,p=0.008),liver herniation(OR=16.955,95%CI=2.342 to 122.767,p=0.005),and gestational age at diagnosis(OR=0.662,95%CI=0.497 to 0.881,p=0.005)were independent mortality-related risk factors of all children with CDH.Ninety-nine of 116 children underwent surgery.After PSM,the postoperative survival rates of the EXIT group and non-EXIT group were 84.6%(22/26)and 76.9%(20/26),respectively(p=0.754).Liver herniation(OR=10.451,95%CI=1.641 to 66.544,p=0.013)and gestational age at diagnosis(OR=0.736,95%CI=0.577 to 0.938,p=0.013)were independent mortality-related risk factors of children after surgery.Conclusion EXIT can be performed safely for selected prenatally diagnosed CDH neonates with potentially better survival and does not cause more maternal complications compared with traditional cesarean section. 展开更多
