Objectives: Complex image registration is crucial in interferometric synthetic aperture sonar (InSAS) signal processing. The registration quality directly influences the generation of interferogram and the subsequent reconstruction of digital elevation model. The traditional global polynomial surface fitting method has the disadvantage of low accuracy for large scene InSAS images. Therefore, a registration method based on piecewise surface fitting is proposed to overcome the problem. Methods: Firstly, the whole image is partitioned into several pieces along range direction with partly overlapped. Then, polynomial surface fitting is performed using control points in each piece. Finally, the global offset surface is obtained by merging those local surface fitting results. Results: Through the simulation and real data experiments, the accuracy of complex image registration using the proposed method is higher than the result of global polynomial surface fitting method. Conclusions: The evaluation has been carried out with the root mean squared error, correlation coefficient, residue numbers, which indicates the validity of the proposed approach.

Objective: To observe the effects of total saponin of Aralia Taibaiensis ( TSAT) on the level of oxidative stress in mice with hepatic fibrosis and to explore its relationship with Keapl-Nrf2-ARE signaling pathway. Methods: Forty mice were randomly divided into four groups: the blank control group, model group, high-dose TSAT group, and low-dose TSAT group, with 10 mice in each group. The mice in the blank control group were injected with equal volume olive oil intraperitoneally, while the mice in the other groups were injected with 0. 15 ml/kg CC14 intraperitoneally, twice a week, for 8 weeks. At the same time, mice in the high-dose and low-dose TSAT groups were separately given 400 and 200 mg/kg TSAT suspension by gavage, and the other two groups were given the equal volume of normal saline by gavage, once a day, for 8 weeks. Eight weeks later, the mice were anesthetized and we took the liver tissues. HE staining was used to observe the morphological changes of liver tissues, and Masson staining was used to detect the changes of collagen fibers; hydroxyproline ( HYP) content in the liver tissues was detected by alkali hydrolysis method, malondialdehyde ( MDA) content in the liver tissues by TBA method and superoxide dismutase (SOD) content by WST-1 method; immunohistochemical SABC method was used to detect the protein expression of nuclear factor Erythroid 2-related factor 2 (Nrf2) and heme oxy-genase- 1 ( H0-1) in the liver tissues. Results: ①Compared with the blank control group, in the model group there were inflammatory cells infiltration, and the livers showed hepatocyte degeneration or necrosis; compared with the model group, TSAT significantly attenuated inflammatory cells infiltration and hepatocyte degeneration or necrosis, and the improvement of the high-dose TSAT group was more significant than that of the low-dose TSAT group. ②MASSON staining showed that there was no collagen fibrosis in the blank control group, a large amount of blue collagen deposition was formed in the model group and collagen fibers were suppressed by TSAT in the liver tissues, and the high-dose TSAT was significantly lower than the low-dose TSAT group. ➂Compared with the blank control group, the model group showed that the content of HYP and MDA was enhanced, the SOD activity was reduced in the liver tissues (both P < 0. 01); compared with the model group, TSAT could reduce the content of HYP and MDA and enhance SOD activity ( all P < 0. 01); compared with the low-dose TSAT group, the content of HYP and MDA was reduced, the SOD activity was enhanced in the liver tissues; the high-dose TSAT group was better than the low-dose TSAT group, and the difference was statistically significant ( all P < 0. 05). Compared with the blank control group, the protein expression of Nrf2 and H0-1 was reduced in the model group ( P < 0. 01); compared with the model group, the protein expression of Nrf2 and H0-1 in the TSAT groups was enhanced (both P < 0. 01); compared with the low-dose TSAT group, the expression of Nrf2 and H0-1 was higher in the high-dose TSAT group than in the low-dose TSAT group, and the difference was statistically significant (P < 0. 05). Conclusion: TSAT can reduce collagen synthesis and secretion in the liver tissues of mice by inhibiting the level of oxidative stress, thereby inhibiting hepatic fibrosis; its anti-oxidative stress mechanism may be related to up-regulation of Nrf2 expression in Keapl-Nrf2- ARE pathway and activation of its downstream antioxidant enzyme H0-1.

Complex image registration is a crucial step in interferometric synthetic aperture sonar (InSAS) signal processing. The registration quality directly influences the generation of interferogram and subsequent reconstruction of digital elevation model (DEM). Utilizing the geometric model of imaging, the rational function relationship between offset and slant range is deduced, thus this paper propose a new InSAS complex image registration method based on second order rational function surface fitting. Compared with the traditional polynomial surface fitting method, the proposed method in this paper has the advantages of higher precision and smaller calculation cost. The evaluation has been carried out using the root mean squared error(RMSE), correlation coefficient,residue numbers and computing time as the criteria. Simulation and real data experiments results indicate the validity of the proposed method. [ABSTRACT FROM AUTHOR]

This paper proposed an efficient range Doppler imaging algorithm for multi-array synthetic aperture sonar (SAS) in shared memory environment based on OpenMP, which solved the imaging problem of low efficiency by multi-core CPU resources. Considered the parallel characteristic of range Doppler algorithm for multi-array SAS, it parallelized the signal processing process such as preprocessing, range compression, phase compensation, range cell migration compensation and azimuth compression based on OpenMP, which greatly enhanced the reconstruction process of SAS image by multi-core CPU resources. The imaging test performed on real data shows that the speedup of the parallel imaging algorithm is up to 19. 86 times, which meets the demand for real-time processing of SAS imaging.

Abstract: Objective To observe the changes in levels of mieroKJNA-146a in the serum of patients with myasthenia gravis (MG), and to analyze the molecular regulatory network of mieroKNA-146a in the pathogenesis of MG by bioinforma-ties. Methods One hundred and eight patients who was first diagnosed MG (MG group), and 50 healthy persons in the same period (control group) were selected, and then the serum mieroKNA-l46a was tested by RT-PCR. The UCSC genome online tools were used to analyze the position and conservatism of mieroKN A-l 46a in the human genome. Targetscan and CoMeTa database was used to predict the inter-target gene of mieroRNA-146a. DAVID database was used to analyse the functional enrichment (GO enrichment) and signal pathway enrichment (KEGG Pathway) of target gene in mieroRNA-146a. Results The serum mieroKN A-l 46a in the MG group was 2.13 ±0.63, which was higher than that (0.86 ±0.38) of control group (P<0.05). Nucleotide sequence was highly conserved in mieroRNA-146a, with 88 types of potential target genes EKRR4, NUMK, CD80, TRAF6, IRAKI, etc. GO analysis showed that the function of mieroKN A-146a target gene mainly focused on the synthesis process of cell proliferation regulation, neuronal differentiation, phosphorus metabolism reaction, immune inflammation, and cytokines, etc. KEGG Pathway showed that mieroKNA-146a target gene mainly focused on loll receptor signaling pathway, neurotransmitter regulatory signaling pathway, EB signaling pathway, and other signaling pathways. Conclusion The level of mieroRNA-146a is elevated in the serum of MG patients, which can participate in the pathogenesis of MG by acting on multiple signaling pathways. [ABSTRACT FROM AUTHOR]
