Fasudil in Combination With Bone Marrow Stromal Cells (BMSCs) Attenuates Alzheimer\u27s Disease-Related Changes Through the Regulation of the Peripheral Immune System.

Alzheimer\u27s disease (AD) is a chronic progressive neurodegenerative disease. Its mechanism is still not clear. Majority of research focused on the central nervous system (CNS) changes, while few studies emphasize on peripheral immune system modulation. Our study aimed to investigate the regulation of the peripheral immune system and its relationship to the severity of the disease after treatment in an AD model of APPswe/PSEN1dE9 transgenic (APP/PS1 Tg) mice. APP/PS1 Tg mice (8 months old) were treated with the ROCK-II inhibitor 1-(5-isoquinolinesulfonyl)-homo-piperazine (Fasudil) (intraperitoneal (i.p.) injections, 25 mg/kg/day), bone marrow stromal cells (BMSCs; caudal vein injections, 1 × 1

Study of Temperature Dependence of the Deposition Rates of Ni-P Based Sonication-Assisted Nanoscale Electroless Composite Plating

In this study, SiCp/Ni-P nano-composite coatings were fabricated on 45 steel substrates under ultrasonic excitation at temperatures from 85 °C to 45 °C. The micro-morphologies and compositions of the coatings were analyzed using Scanning Electron Microscopy (SEM) and Energy Dispersion Spectrum (EDS). The deposition rates of the different processes were then investigated using the polarization curve method, the weighing method, and the film thickness method. The effects of sonication on the coating process were also investigated. The results reveal that free energy decreased to 16.38 kJ/mol, which can be attributed to the positive effect of sonication on the reaction activity. Furthermore, the deposition rates of the composite plating decreased with the process temperature. Specifically, the deposition rates measured by the polarization curve method, weighing method, and film thickness method decreased from 0.625 mg/(cm2·h) to 0.116 mg/(cm2·h), from 3.9 mg/(cm2·h) to 1.6 mg/(cm2·h), and from 36.64 μm/h to 7.05 μm/h, respectively.

Fasudil in Combination With Bone Marrow Stromal Cells (BMSCs) Attenuates Alzheimer’s Disease-Related Changes Through the Regulation of the Peripheral Immune System

Majority of research focused on the central nervous system (CNS) changes, while few studies emphasize on peripheral immune system modulation. Our study aimed to investigate the regulation of the peripheral immune system and its relationship to the severity of the disease after treatment in an AD model of APPswe/PSEN1dE9 transgenic (APP/PS1 Tg) mice. APP/PS1 Tg mice (8 months old) were treated with the ROCK-II inhibitor 1-(5-isoquinolinesulfonyl)- homo-piperazine (Fasudil) (intraperitoneal (i.p.) injections, 25 mg/kg/day), bone marrow stromal cells (BMSCs; caudal vein injections, 1 × 106 BMSCs /time/mouse), Fasudil combined with BMSCs, or saline (i.p., control) for 2 months. Morris water maze (MWM) test was used to evaluate learning and memory. The mononuclear cells (MNCs) of spleens of APP/PS1 Tg mice were analyzed using flow cytometry for CD4+ T-cells, macrophages, and the pro-inflammatory and anti-inflammatory molecules of the macrophages. Immunohistochemical staining was used to examine the expression of ROCK-II in the spleens of APP/PS1 Tg mice. The MWM test showed improved spatial learning ability in APP/PS1 Tg mice treated with Fasudil or BMSCs alone or in combination, compared to untreated APP/PS1 Tg mice. Fasudil combined with BMSCs intervention significantly promoted the proliferation of CD4+/CD25+ and CD4+/ IL-10 lymphocytes, induced the release of cytokine factors, and regulated the balance of the immune system to work functionally. It also shifted M1 (MHC-II, CD86) to M2 (IL-10, CD206) phenotype of macrophages of CD11b and significantly enhanced the anti-inflammatory and phagocytic abilities (CD16/32) of macrophages of CD11b. Immunohistochemical staining showed significantly decreased expression of ROCK-II in mice treated with combination of Fasudil with BMSCs as compared to saline control. Fasudil in combination of BMSCs improved cognition of APP/PS1 Tg mice through the regulation of the peripheral immune system, including reduction of ROCK-II expression and increased proportion of anti-inflammatory M2 mononuclear phenotype and phagocytic macrophages in the spleen of the peripheral immune system. The latter was achieved through the communication between brain and spleen to improve the immunoregulation of CNS and AD disease conditions

Experimental Study of Shell-Side Fogging Condensation of a Mixture

Fog formation occurs if the vapor pressure in the gas-phase is higher than the saturated vapor pressure and the bulk temperature is lower than its saturation temperature (supersaturated) for condensation in the presence of non-condensable gases. Generally, fogging is formation of entrained small droplets mixing in the vapor-gas stream, and the vapor condenses at the mist-flow and share-controlled flow regime. The phenomenon and mechanism of fogging need to be considered for determining condensation rate and separation of the condensate from vapor-gas phase for the down-stream process. The experimental study of shell-side condensation using steam mixing with non-condensable air was conducted in a shell-side horizontal baffled tube bundle. Experimental data has been obtained including visualization findings using high-speed photograph. The characteristics of fog formation related to the heat and mas transfer performance are analyzed based on experimental data and observation. The general equation for determining fog formation (degree of supersaturation) is evaluated with experimental data. Results confirm that the transition band of fogging formation is in the range of S = 1.0 to 1.75. This paper presents experimental data and visualization findings on fogging characteristics and heat transfer performance for condensation in the presence of non-condensable gas.</jats:p

The PSRS Algorithm based on Synchronous Barrier

Abstract: The biggest characteristic of LogGP model based on LogP mode is sending long messages, if all the elements to be sent are seem as a long message and sent in a single processor, a sorting algorithm should be introduced to merge those elements, but the algorithm designed in the LogP mode is heavily dependent on the accuracy of parameters such as l, o, g, p. However, parameters are often inaccurate in reality. This may lead to message traffic congestion in the transfer process and the degradation of Communication performance of system. Therefore, this study proposes a new algorithm, that is, synchronization barrier is introduced into PSRS algorithm, which can improve LogGP Model further. Network congestion will be avoided when sending a long message and system performance will be improved .The barrier synchronization method can be applied to other algorithms of LogGP model, so it has a certain practicality
