Purpose: Gastric cancer (GC) is the second most lethal cancer globally and is associated with poor prognosis. Fatty acid-binding proteins (FABPs) can regulate biological properties of carcinoma cells. FABP5 is overexpressed in many types of cancers; however, the role and mechanisms of action of FABP5 in GC remain unclear. In this study, we aimed to evaluate the clinical and biological functions of FABP5 in GC. Materials and Methods: We assessed FABP5 expression using immunohistochemical analysis in 79 patients with GC and evaluated its biological functions following in vitro and in vivo ectopic expression. FABP5 targets relevant to GC progression were determined using RNA sequencing (RNA-seq). Results: Elevated FABP5 expression was closely associated with poor outcomes, and ectopic expression of FABP5 promoted proliferation, invasion, migration, and carcinogenicity of GC cells, thus suggesting its potential tumor-promoting role in GC. Additionally, RNA-seq analysis indicated that FABP5 activates immune-related pathways, including cytokine-cytokine receptor interaction pathways, interleukin-17 signaling, and tumor necrosis factor signaling, suggesting an important rationale for the possible development of therapies that combine FABP5-targeted drugs with immunotherapeutics. Conclusions: These findings highlight the biological mechanisms and clinical implications of FABP5 in GC and suggest its potential as an adverse prognostic factor and/or therapeutic target.

The elementary excitation spectra of a one-dimensional ferrimagnetic diamond chain in the spin- 1/2 XY model at low temperatures have been calculated by using an invariant eigen-operator (IEO) method, the energies of elementary excitations in different specific cases are discussed, and the analytic solutions of three critical magnetic field intensities (<i>H</i><sub>C1</sub>, <i>H</i><sub>C2</sub>, and <i>H</i><sub>peak</sub>) are given. The magnetization versus external magnetic field curve displays a 1/3 magnetization plateau at low temperatures, in which <i>H</i><sub>C1</sub> is the critical magnetic field intensity from the disappearance of the 1/3 magnetization plateau to spin-flop states, <i>H</i><sub>C2</sub> is the critical magnetic field intensity from spin-flop states to the saturation magnetization, and Hpeak is the critical magnetic field intensity when the temperature magnetization shows a peak in the external magnetic field. The temperature dependences of the magnetic susceptibility and the specific heat show a double peak structure. The entropy and the magnetic susceptibility versus external magnetic field curves also exhibit a double peak structure, and the positions of the two peaks correspond to <i>H</i><sub>C1</sub> and <i>H</i><sub>C2</sub>, respectively. This derives from the competition among different types of energies: the temperature-dependent thermal disorder energy, the potential energy of the spin magnetic moment, the ferromagnetic exchange interaction energy, and the anti-ferromagnetic exchange interaction energy. However at low temperatures, the specific heat as a function of external magnetic field curve exhibits minima at the above two critical points (<i>H</i><sub>C1</sub> and <i>H</i><sub>C2<sub>). The origins of the above phenomena are discussed in detail.
Model-Deviation Compensation Control for Uncertain Systems with Time Delay
Xiao-Jie Sun,Hua Ye,Shu-Min Fei 제어로봇시스템학회 2010 제어로봇시스템학회 국제학술대회 논문집 Vol.2010 No.10
A novel model-deviation compensation control strategy is developed for a class of uncertain systems with time delay in this paper. Taking an identified second-order plus dead-time (SOPDT) process for example, the whole design methodology is proposed, which integrates the prediction model, the sliding function design, the equivalent control term and the model-deviation compensation control law. Firstly the delay-ahead predictor with the feedback correction is constructed to weaken the affection of time delay in the system. Then by improving the classical sliding mode control, after obtaining the equivalent control term, the model-deviation compensation term is derived from the actual regulated response and the deviation to be eliminated, so that the modeling uncertainties and external disturbances can be restrained. Finally the establishment and feasible solution of LMI guarantee that the system output reaches the desired value. The simulation results verify the effectiveness of the proposed strategy.

This paper reports the results of a seismic performance study of a precast shear wall with a new horizontal connection. The new connection is the rabbet-unbonded horizontal connection, which is composed of rabbets and unbonded rebar segments. The rabbets are used to improve the shear capacity and prevent slippage of the connection, and the unbonded rebar segments are used to improve the ductility and energy dissipation. Three specimens were tested with different parameters under cyclic quasi-static loading. The test results showed that the specimen with a larger unbonded level had a richer hysteresis curve, larger ductility, larger energy dissipation, and slightly smaller bearing capacity. Moreover, in relation to the stiffness degradation, in the initial stage, the specimen with a larger unbonded level had a smaller stiffness, whereas in the last stage, the stiffnesses were similar regardless of the unbonded level. A parameter analysis using a finite element model proved that the ductility and energy dissipation of a shear wall with the rabbet-unbonded horizontal connection increased with the unbonded length and level. In addition, when the axial compression ratio increased, the bearing capacity increased, but the load-displacement curves decreased more rapidly. It was concluded that the unbonded length and unbonded level could effectively improve the ductility and energy dissipation of a shear wall. However, they should not be too large under high pressure, and the design suggestions for the new connection need further research considering other factors.

Background: Ginseng (G) and Ligustrum lucidum Ait (LLA) are core traditional Chinese medicines intreating myelosuppression formula. The present study was designed to profile effect of G and LLA herbpair (G-LLA) on myelosuppressed mice. Methods: The mice myelosuppression model was established by intraperitoneal (i.p.) injection ofcyclophosphamide (Cy). Hematopoietic function of bone marrow was measured by hemopoietic progenitorcell culture and peripheral blood count, and serum hemopoietic factors were tested by enzymelinkedimmunosorbent assay. Bone marrow cell cycle was performed by flow cytometry. HPLC was usedto measure 20 potential chemical components related to myelosuppression, including ginsenoside Rg1,Re, Rb1, Rc, Rb2, Rb3, Rd, Rk3, Rh4, 20 (S)-Rg3, 20 (R)-Rg3, Rk1, Rg5, salidroside, and so on. Results: G, LLA, and G-LLA improved the amount of peripheral blood cells and bone marrow cellsof myelosuppressed mice (P < 0.01). They significantly increased the colony quantity of colony-formingunitegranulocyte macrophage, burst-forming unit erythroid, colony-forming unit erythroid, and colony-forming unit megakaryocyte and amount of G2/M and S phase cells (P < 0.01). They also significantlydecreased the amount of hematopoiesis-related cytokines (P < 0.01). The content of chemicalcomponents in G-LLA changed, and the change of rare saponin was the most obvious. Conclusion: These results show that G-LLA herb pair might produce synergistic or complementarycompatibility effects on bone marrow suppression after chemotherapy. It suggests that the substancebasis of G-LLA for treating bone marrow suppression may be effective chemical components.

With the aim of improving the robustness of the hybrid energy storage system(HESS) and avoiding overcharging and reasonably managing state of charge (SOC), this paper proposed a HESS control strategy employing integral backstepping (IBS) method based on SOC. Firstly, on the basis of the hybrid energy storage control strategy of conventional filtering technology (FT), the current inner loop PI controller was changed into an controller employing IBS method to improve the robustness shown by the energy storage system (ESS) against system parameter perturbation or external disturbance. The current controller of the HESS employing inner loop integral backstepping method was designed and the Lyapunov stability was proven. Secondly, to avoid overcharging and over-discharging of the HESS and to reasonably manage SOC, an energy management strategy based on SOC was proposed to generate the current reference value of the inner loop controller employing integral backstepping method, and the energy management strategy based on SOC was designed as well. Finally, the simulation model of the HESS employing integrated backstepping method based on SOC was established, and the feasibility of this method was verified through simulation. It was shown by the results obtained from the simulation that the HESS control strategy employing integrated backstepping method based on SOC had greater anti-interference ability and improved the robustness of the system, in comparison with the control strategy of FT (PI) and FT (IBS) hybrid energy storage. In the meanwhile, the upper and lower limits of SOC of the ESS are supposed to be managed to avoid overcharging and over-discharging and to extend the life of the ESS.
