Microencapsulation improves inhibitory effects of transplanted olfactory ensheathing cells on pain after sciatic nerve injury

Olfactory bulb tissue transplantation inhibits P2X2/3 receptor-mediated neuropathic pain. However, the olfactory bulb has a complex cellular composition, and the mechanism underlying the action of purified transplanted olfactory ensheathing cells (OECs) remains unclear. In the present study, we microencapsulated OECs in alginic acid, and transplanted free and microencapsulated OECs into the region surrounding the injured sciatic nerve in rat models of chronic constriction injury. We assessed mechanical nociception in the rat models 7 and 14 days after surgery by measuring paw withdrawal threshold, and examined P2X2/3 receptor expression in L_(4-5) dorsal root ganglia using immunohistochemistry. Rats that received free and microencapsulated OEC transplants showed greater withdrawal thresholds than untreated model rats, and weaker P2X2/3 receptor immunoreactivity in dorsal root ganglia. At 14 days, paw withdrawal threshold was much higher in the microencapsulated OEC-treated animals. Our results confirm that microencapsulated OEC transplantation suppresses P2X2/3 receptor expression in L4-5 dorsal root ganglia in rat models of neuropathic pain and reduces allodynia, and also suggest that transplantation of microencapsulated OECs is more effective than transplantation of free OECs for the treatment of neuropathic pain.
Localized regulation of the axon shaft during the emergence of collateral branches

The ability of the axon to form de novo collateral branches along its length is fundamental to the establishment of complex patterns of connectivity during development and is also a major response of many axonal populations following injury. The emergence of branches is under both positive and negative control by extracellular signals. How the site of branch formation is determined is a fundamental question regarding the formation of branches. In theory, the whole axon shaft has the potential to give rise to a branch, but yet branches form only at specific sites. This feature of the formation of branches is emphasized by studies in which nerve growth factor (NGF), covalently attached to 10 micron beads, was applied locally along embryonic sensory axons (Gallo and Letourneau, 1998). Although contact of the beads with the axon shaft was able to drive the formation of a branch at the sites of contact, even after 3 hours of continuous contact only 46% of sites gave rise to a branch. Similarly, when NGF is bath applied to cultured sensory neurons, and thus the whole surface of the axon is exposed to NGF, axons usually only generate a maximum of 4-6 branches along the distal 100 microns of the axon, a response that is maximal by 30 minutes of treatment. Recent work, from our laboratory and others, has begun to shed light on why axons form branches at specific sites.
Stoppa入路在骨盆与髋臼骨折治疗中的应用研究进展

Judet等于1960年开始将髂腹股沟入路应用于髋臼骨折的治疗,并于1964年对髋臼骨折的分型及治疗方案进行了详细的描述,经过创伤骨科医生的广泛应用,目前已成为不稳定型骨盆骨折中耻骨上支骨折和髋臼前方骨折的经典手术入路。该入路能充分显露前柱前壁、方形区表面及耻骨上下支区域的术野,同时不干扰髋关节外展肌,有利于患者的早期康复。但该入路的切口长,需要3个窗口的显露;若存在耻骨联合分离,则需4个窗口显露,显露时间长,术中钢板塑形困难,同时因局部解剖复杂,术中易合并血管、神经损伤。鉴于此,国内外创伤骨科医生将此入路进行了改良,将Stoppa入路引入骨盆与髋臼骨折的手术治疗。我们结合国内外文献将其应用研究进展进行阶段性综述。
胆汁淤积性肝病的诊断与治疗

胆汁淤积是指胆汁流的形成和排泌障碍,可由肝细胞或胆管上皮的胆汁形成、分泌障碍或胆汁流的阻断引起。胆汁淤积性肝病包括原发性胆汁性肝硬化(primary biliary cirrhosis, PBC)、原发性硬化性胆管炎(primary sclerosing cholangitis, PSC)、IgG4相关硬化性胆管炎(IgG4-related sclerosing cholangitis,IgG4-SC)、妊娠期肝内胆汁淤积(intrahepatic cholestasis of pregnancy, ICP)以及遗传性疾病如进行性家族性肝内胆汁淤积(progressive familial intrahepatic cholestasis, PFIC)等。
QoS-Based Service Selection with Lightweight Description for Large-Scale Service-Oriented Internet of Things

Quality of Service (QoS)-based service selection is the key to large-scale service-oriented Internet of Things (IOT), due to the increasing emergence of massive services with various QoS. Current methods either have low selection accuracy or are highly time-consuming (e.g., exponential time complexity), neither of which are desirable in large-scale IOT applications. We investigate a QoS-based service selection method to solve this problem. The main challenges are that we need to not only improve the selection accuracy but also decrease the time complexity to make them suitable for large-scale IOT applications. We address these challenges with the following three basic ideas. First, we present a lightweight description method to describe the QoS, dramatically decreasing the time complexity of service selection. Further more, based on this QoS description, we decompose the complex problem of QoS-based service selection into a simple and basic sub-problem. Finally, based on this problem decomposition, we present a QoS-based service matching algorithm, which greatly improves selection accuracy by considering the whole meaning of the predicates. The traces-driven simulations show that our method can increase the matching precision by 69% and the recall rate by 20% in comparison with current methods. Moreover, theoretical analysis illustrates that our method has polynomial time complexity, i.e., O.m~2 × n/, where m and n denote the number of predicates and services, respectively.
一氧化氮在休克血管低反应性发生机制中的作用

失血性休克、脓毒血症引起的血管功能受损是重症休克导致患者多器官衰竭乃至死亡的重要原因之一。休克后血管功能受损主要表现血管平滑肌功能受损和血管内皮功能紊乱。血管平滑肌损伤导致休克患者的血压逐步恶化,表现为血管低反应性,是重症休克患者死亡的重要原因之一。血管内皮损伤会导致微血管血流受阻、黏附增强、白细胞与血小板激活、凝血异常和重要器官的血液灌注与能量代谢异常,加重器官损伤。研究发现,一氧化氮(NO),在调节血管舒缩过程中起着非常重要的作用,通过影响血管平滑肌细胞(VSMCs)和血管内皮细胞(VECs)的功能参与失血性休克、感染性休克晚期血管低反应性的发生、发展。本文综述NO在休克后血管低反应性中的作用,为防治休克后血管低反应性提供理论参考。

机器学习在脑肿瘤MRI中的发展及应用

机器学习在脑肿瘤MRI中的应用已经成为当下研究热点,其对于脑肿瘤在术前、术中、术后各期的诊断和治疗均有较大临床价值。目前,机器学习在脑肿瘤的自动分割、分类和分型的辅助诊断、术中路径的辅助分析、预后预测、数据收集等方面都取得了较大进展,但其在广泛投入临床应用前尚需克服一些限制阻碍:期望未来临床医师可以将两个领域更好地结合,使其成为脑肿瘤诊疗过程中的重要工具。
食用单支含乳棒棒糖对健康志愿者胃残余容积的影响

禁饮禁食是术前准备的主要内容,是保证胃排空和降低麻醉期间反流误吸风险的重要措施。但禁饮禁食给患者造成的饥饿感和可能的低血糖也是影响患者舒适度和安全的重要议题。既往研究表明,术前咀嚼口香糖可以极大地解患者术前的焦虑情绪和不适感,而不会增加患者的胃容积,也不会延缓患者的胃排空。但中国患者对口香糖的接受度较欧美患者低,而且咀嚼口香糖存在风险,对于低龄患者可能造成吞食,对于高龄患者可能影响不稳定的牙齿,若患者麻醉前未吐出口香糖而未被发现,可能造成麻醉诱导后梗阻气管或食管。棒棒糖对于各年龄段患者而言接受度均较好,目前临床上术前还有芬太尼或咪达唑仑的棒棒糖剂型。但含乳棒棒糖的牛乳成分是否增加残余胃容积(gastric residual volume,GRV), 从而增加反流误吸的风险,目前尚未明确。本研究旨在观察含乳棒棒糖对健康志愿者GRV的影响,为术前食用含乳棒棒糖的安全性提供依据。
线粒体内质网耦联在糖尿病肾病足细胞损伤中的作用及机制

糖尿病肾病(diabetic kidney disease,DKD)为糖尿病常见的微血管并发症,蛋白尿是其特征性标志,而足细胞损伤是DKD蛋白尿发生发展的中心环节。线粒体内质网耦联(mitochondria - associated endoplasmic reticulum membranes, MAMs)指真核细胞内线粒体外膜与内质网膜之间“招募”一系列蛋白质形成的紧密物理连接,MAMs已被发现参与了多种病理生理过程。Ca~(2+)稳态失调、内质网应激和线粒体功能障碍既是DKD发生发展的重要因素,同时也受MAMs的调控,影响足细胞的正常生理功能。近年相继有DKD足细胞中的MAMs发生了结构或功能改变的研究报道。本文旨在系统回顾本领域相关研究,综述MAMs在DKD足细胞损伤中可能的作用及其机制。

Adaptive Model Predictive Control for Yaw System of Variable-speed Wind Turbines

Due to varying characteristics of the wind condition, the performance of the wind turbines can be optimized by adapting the parameters of the control system. In this letter, an adaptive technique is proposed for the novel model predictive control (MPC) for the yaw system of the wind turbines. The control horizon is adapted to the one with the best predictive performance among multiple control horizons. The adaptive MPC is demonstrated by simulations using real wind data, and its performance is compared with the baseline MPC at fixed control horizon. Results show that the adaptive MPC provides better comprehensive performance than the baseline ones at different preview time of wind directions. Therefore, the proposed adaptive technique is potentially useful for the wind turbines in the future.
A Risk-Averse Remaining Useful Life Estimation for Predictive Maintenance

Remaining useful life(RUL)prediction is an advanced technique for system maintenance scheduling.Most of existing RUL prediction methods are only interested in the precision of RUL estimation;the adverse impact of overestimated RUL on maintenance scheduling is not of concern.In this work, an RUL estimation method with risk-averse adaptation is developed which can reduce the over-estimation rate while maintaining a reasonable under-estimation level.The proposed method includes a module of degradation feature selection to obtain crucial features which reflect system degradation trends.Then, the latent structure between the degradation features and the RUL labels is modeled by a support vector regression(SVR)model and a long short-term memory(LSTM)network, respectively.To enhance the prediction robustness and increase its marginal utility, the SVR model and the LSTM model are integrated to generate a hybrid model via three connection parameters.By designing a cost function with penalty mechanism, the three parameters are determined using a modified grey wolf optimization algorithm.In addition, a cost metric is proposed to measure the benefit of such a risk-averse predictive maintenance method.Verification is done using an aero-engine data set from NASA.The results show the feasibility and effectiveness of the proposed RUL estimation method and the predictive maintenance strategy.
Effects of oxytetracycline dihydrate and sulfamethoxazole on Microcystis aeruginosa and Chlamydomonas microsphaera

The increasing use of pharmaceuticals has become a major environmental issue in China. The presence of antibiotics in water may have deleterious effects on non-target aquatic organisms such as microalgae. In this study, a cyanobacterium and an alga species in surface waters, Microcystis aeruginosa and Chlamydomonas microsphaera, were exposed to 0, 0.1, 0.5, 1.0, 2.0, 5.0, 10.0, and 20.0 mg/L of oxytetracycline dihydrate (OXY) and sulfamethoxazole (SMZ) for 96 h to determine the effects of these antibiotics on the growth and surface morphology. Moreover, the photosynthetic activity and the contents of superoxide dismutase (SOD), malondialdehyde (MDA), and protein were measured to examine the biochemical characteristics of M. aeruginosa and C. microsphaera under OXY and SMZ stress. The effects of both antibiotics on the growth of both species were concentration-dependent and characterized by low-dose stimulation and high-dose inhibition. C. microsphaera was more sensitive to both antibiotics than M. aeruginosa was. The algal cell membranes of both species disintegrated after exposure to a high concentration of OXY. All of the physiological parameters measured in this study were relatively stable at low concentrations of OXY and SMZ. After exposure to high concentrations of OXY and SMZ, photosynthetic activity decreased significantly, whereas lipid peroxidation and the abundance of SOD, MDA, and protein increased significantly. Thus, low-dose antibiotics may increase algal blooms in eutrophic waters.
The sensitivity of numerical simulation to vertical mixing parameterization schemes: a case study for the Yellow Sea Cold Water Mass

The vertical mixing parameterization scheme, by providing the effects of some explicitly missed physical processes and more importantly closing the energy budgets, is a critical model component and therefore imposes significant impacts on model performance. The Yellow Sea Cold Water Mass (YSCWM), as the most striking and unique phenomenon in the Yellow Sea during summer, is dramatically affected by vertical mixing process during its each stage and therefore seriously sensitive to the proper choice of parameterization scheme. In this paper, a hindcast of YSCWM in winter of 2006 was implemented by using the Regional Ocean Modeling System (ROMS). Three popular parameterization schemes, including the level 2.5 Mellor-Yamada closure (M-Y 2.5), Generic Length Scale closure (GLS) and K-Profile Parameterization (KPP), were tested and compared with each other by conducting a series of sensitivity model experiments. The influence of different parameterization schemes on modeling the YSCWM was then carefully examined and assessed based on these model experiments. Although reasonable thermal structure and its seasonal variation were well reproduced by all schemes, considerable differences could still be found among all experiments. A warmer and spatially smaller simulation of YSCWM, with very strong thermocline, appeared in M-Y 2.5 experiment, while a spatially larger YSCWM with shallow mixed layer was found in GLS and KPP schemes. Among all the experiments, the discrepancy, indicated by core temperature, appeared since spring, and grew gradually by the end of November. Additional experiments also confirmed that the increase of background diffusivity could effectively weaken the YSCWM, in either strength or coverage. Surface wave, another contributor in upper layer, was found responsible for the shrinkage of YSCWM coverage. The treatment of wave effect as an additional turbulence production term in prognostic equation was shown to be more superior to the strategy of directly increasing diffusivity for a coastal region.
Influence of sequential tropical cyclones on phytoplankton blooms in the northwestern South China Sea

Upper ocean responses to the passage of sequential tropical cyclones over the northwestern South China Sea (SCS) in 2011 were investigated using satellite remote sensing data, Argo reanalysis data, and an array of mooring data. We found that the sea surface low temperature region lasted for more than 38 days and two phytoplankton blooms occurred after the passage of sequential tropical cyclones. The upper ocean cooling reached 2-5 °C with a right-side bias was observed along the typhoon track to about 200 km. The maintenance of low temperature region and the two phytoplankton blooms were mainly driven by upwelling and near-inertial turbulence mixing induced by the sequential tropical cyclones. The first phytoplankton bloom appeared on the 7 th day after the passage of the three tropical cyclones, and the chlorophyll- a (chl- a) concentration increased by 226%, which may be mainly driven by typhoons induced upwelling. The second phytoplankton bloom occurred on the 30 th day, the chl- a concentration increased by 290%. Further analysis suggested that only the typhoons with similar characteristics as Nesat and Nalgae can induce strong near-inertial oscillation (NIO). Strong turbulent mixing associated with the near-inertial baroclinic shear instability lasted for 26 days. The measured mean eddy diffusivity in the upper ocean was above 10 -4 m 2 /s after typhoon Nesat. Enhancement of the turbulent mixing in the upper ocean helped to transport nutrient-rich cold waters from the deep layer to the euphotic layer, and is a major mechanism for the long-term maintenance of low temperature region as well as the second phytoplankton bloom.
Output Constrained Adaptive Controller Design for Nonlinear Saturation Systems

This paper considers the adaptive neuro-fuzzy control scheme to solve the output tracking problem for a class of strict-feedback nonlinear systems.Both asymmetric output constraints and input saturation are considered.An asymmetric barrier Lyapunov function with time-varying prescribed performance is presented to tackle the output-tracking error constraints.A high-gain observer is employed to relax the requirement of the Lipschitz continuity about the nonlinear dynamics.To avoid the “explosion of complexity”, the dynamic surface control(DSC)technique is employed to filter the virtual control signal of each subsystem.To deal with the actuator saturation, an additional auxiliary dynamical system is designed.It is theoretically investigated that the parameter estimation and output tracking error are semi-global uniformly ultimately bounded.Two simulation examples are conducted to verify the presented adaptive fuzzy controller design.
Multilocus phylogeny suggests a distinct species status for the Nepal population of Assam macaques (Macaca assamensis): implications for evolution and conservation

Phylogenetic relationships within the sinica-group of macaques based on morphological, behavioral, and molecular characteristics have remained controversial. The Nepal population of Assam macaques(Macaca assamensis)(NPAM), the westernmost population of the species, is morphologically distinct but has never been used in phylogenetic analyses. Here, the phylogenetic relationship of NPAM with other congeners was tested using multiple mitochondrial and Ychromosomal loci. The divergence times and evolutionary genetic distances among macaques were also estimated. Results revealed two major mitochondrial DNA clades of macaques under the sinica-group: the first clade included M. thibetana, M. sinica, and eastern subspecies of Assam macaque(M. assamensis assamensis); the second clade included M. radiata together with species from the eastern and central Himalaya, namely, M. leucogenys, M. munzala, and NPAM. Among the second-clade species, NPAM was the first to diverge from the other members of the clade around 1.9 million years ago. Our results revealed that NPAM is phylogenetically distinct from the eastern Assam macaques and closer to other species and hence may represent a separate species. Because of its phylogenetic distinctiveness, isolated distribution, a nd small population size, the Nepal population of sinica-group macaques warrants detailed taxonomic revision and high conservation priority.
Computation of the atmosphere-less light intensity curve during a total solar eclipse by using Lunar Reconnaissance Orbiter topography data and the DE430 astronomical ephemeris

Observations of the sky irradiation intensity in the visible wavelengths during a solar eclipse permit to model the Sun diameter, a key number to constrain the internal structure of our star. In this paper, we present an algorithm that takes advantage of the precise Moon topography from Lunar Reconnaissance Orbiter to compute, with a high resolution in time, the geometrical part (i.e. top-of-atmosphere, and for a given wavelength) of the sky irradiation at any given location on the Earth during these events. The algorithm is also able to model the Baily’s beads. We give as an application the theoretical computation of the light curve corresponding to the solar eclipse observed at Lakeland (Queensland, North Australia) on 2012 November 13. The application to real data, with the introduction of atmospheric and instrumental passbands, will be considered in a forthcoming paper.
The composite X-ray spectra of radio-loud and radio-quiet SDSS quasars

We present a study of the X-ray emission for a sample of radio-detected quasars constructed from the cross-matches between SDSS, FIRST catalogs and XMM-Newton archives. A sample of radio-quiet SDSS quasars without FIRST radio detection is also assembled for comparison. We construct the optical and X-ray composite spectra normalized at rest frame 4215A (or 2200A) for both radio-loud quasars (RLQs) and radio-quiet quasars (RQQs) at z ≤ 3.2, with matched X-ray completeness of 19%, redshift and optical luminosity. While the optical composite spectrum of RLQs is similar to that of RQQs, we find that RLQs have a higher X-ray composite spectrumthan RQQs, consistent with previous studies in the literature. By dividing the radio-detected quasars into radio loudness bins, we find the X-ray composite spectra are generally higher with increasing radio loudness. Moreover, a significant correlation is found between the optical-to-X-ray spectral index and radio loudness, and there is a unified multi-correlation between the radio and X-ray luminosities and radio loudness in radio-detected quasars. These results could be possibly explained with the corona-jet model, in which the corona and jet are directly related.
Power Allocation for Video Segment Based Caching Strategy in F-RAN Architecture

The concept of edge network caching has been proposed to alleviate the excessive pressure on the core networks.Furthermore,video segment caching technology,a method to cut the whole video into segments and cache them separately,has brought a novel idea to solve the caching problem in the smaller space for massive data.The adoption of segment caching in edge networks will divide the simple video transmission process into two coupling stages because of separate data caching,which leads to more complicated resource allocation.In this paper,this problem is discussed,and its mathematical model is established to minimize the energy consumption of video transmissions.By introducing an efficient prediction window of channel fading,an optimal dynamic scheduling algorithm based on Qlearning is proposed to minimize power consumption while ensuring smooth video streaming.The proposed Q-learning algorithm is simulated and the impacts of channel state,target video bit rate and largescale channel parameter are evaluated.Simulation results show that the proposed method can effectively reduce the total power consumption while ensuring the smooth playback of video service,thanks to the fact that the proposed method is intelligent which can effectively utilize idle resources in favorable channel states.
