Abstract As ocular computer-aided diagnostic (CAD) tools become more widely accessible, many researchers are developing deep learning (DL) methods to aid in ocular disease (OHD) diagnosis. Common eye diseases like cataracts (CATR), glaucoma (GLU), and age-related macular degeneration (AMD) are the focus of this study, which uses DL to examine their identification. Data imbalance and outliers are widespread in fundus images, which can make it difficult to apply many DL algorithms to accomplish this analytical assignment. The creation of effcient and reliable DL algorithms is seen to be the key to further enhancing detection performance. Using… More >

Abstract 1,3-Dioleoyl-2-palmitoylglycerol (OPO) has been a hotspot of functional oils research in recent years, but due to the high cost of sn-1,3 specific lipase in enzymatic synthesis and the lack of biocatalyst stability, large-scale industrial application is difficult. In this study, the prepared magnetic ZnFe₂O₄ was functionalized with dopamine to obtain ZnFe₂O₄@PDA, and the nano-biocatalyst ZnFe₂O₄@PDA@RML was prepared by immobilizing sn-1,3 specific lipase of Rhizomucor miehei lipase (RML) via a cross-linking method. The existence of RML on ZnFe₂O₄@PDA was confirmed by XRD, FTIR, SEM, and TEM. This strategy proved to be simple and effective because the lipase immobilized on… More > Graphic Abstract

Abstract Nowadays in the medical field, imaging techniques such as Optical Coherence Tomography (OCT) are mainly used to identify retinal diseases. In this paper, the Central Serous Chorio Retinopathy (CSCR) image is analyzed for various stages and then compares the difference between CSCR before as well as after treatment using different application methods. The first approach, which was focused on image quality, improves medical image accuracy. An enhancement algorithm was implemented to improve the OCT image contrast and denoise purpose called Boosted Anisotropic Diffusion with an Unsharp Masking Filter (BADWUMF). The classifier used here is to More >

Abstract

Agave salmiana ash and poultry eggshell powder as CaO sources were used for obtaining nanostructured hydroxyapatite (HAP). The synthesis was carried out by the Green Chemistry Hydrothermal Biosynthesis at 180°C with a pH of 5, by reacting CaO from Agave Salmiana ash and Eggshell powder, with dibasic calcium phosphate (CaHPO₄•2H₂O) in an aqueous solution, with Aloe barbadensis extract. The product was characterized by X-ray diffraction, Fourier-transform infrared spectroscopy (FT-IR), Scanning Electron Microscopy (SEM), and Transmission Electron Microscopy (TEM). The size and shape of the hydroxyapatite particles changed dramatically in the presence of Aloe barbadensis. Large crystals of Hydroxyapatite were observed

Abstract Excessive fat ectopically deposited in the non-adipose tissues is considered as one of the leading causes of myopathy. The aim of this study was to investigate the role of Dihydroartemisinin (DHA) in palmitate (PAL)-incubated H9c2 cells (lipotoxicity-induced cell injury model). Cell viability of PAL-treated cells was determined by MTT assay, and apoptotic regulators were examined by qRT-PCR and western blot analysis, in the absence or in the presence of DHA, respectively. Expression levels of miR-133b and Sirt1 were also evaluated by qRT-PCR and western blotting examination. PAL decreased the viability of H9c2 cells and enhanced More >

Abstract This study addressed sufficient conditions for the robust monotonic convergence of repetitive discrete-time linear parameter varying systems, with the parameter variation rate bound. The learning law under consideration is an anticipatory iterative learning control. Of particular interest in this study is that the iterations can eliminate the influence of disturbances. Based on a simple quadratic performance function, a sufficient condition for the proposed learning algorithm is presented in terms of linear matrix inequality (LMI) by imposing a polytopic structure on the Lyapunov matrix. The set of LMIs to be determined considers the bounds on the More >

Abstract Vitiligo results in an autoimmune disorder destructing skin pigment cells, melanocytes (Mcs). This study aimed to investigate whether Astragaloside IV (AIV) could efficiently induce differentiation of bone marrow mesenchymal stem cells (BMMSCs) into Mcs. BMMSCs were induced and differentiated into Mcs with 0.1, 0.2, and 0.4 mg/L AIV during 150-day. Morphologic changes of differentiated cells were observed. Levels of some melanocytic specific genes (TRP-1, TRP-2, MART-1, Mitf) were measured with quantitative polymerase chain reaction (qPCR) at 90, 120, and 150 days of induction. After 90-day induction, the differentiated cells with 0.4 mg/L AIV demonstrated the typical morphology… More >

Abstract The two-dimensional (2-D) system has a wide range of applications in different fields, including satellite meteorological maps, process control, and digital filtering. Therefore, the research on the stability of 2-D systems is of great significance. Considering that multiple systems exist in switching and alternating work in the actual production process, but the system itself often has external perturbation and interference. To solve the above problems, this paper investigates the output feedback robust H_∞ stabilization for a class of discrete-time 2-D switched systems, which the Roesser model with uncertainties represents. First, sufficient conditions for exponential stability are… More >

Abstract Nous décrivons les principales tumeurs malignes intraoculaires, les tumeurs conjonctivales et citons également quelques tumeurs orbitopalpébrales. Les tumeurs malignes primitives intraoculaires sont le rétinoblastome chez l’enfant et le mélanome uvéal chez l’adulte. Le mélanome uvéal métastase essentiellement au niveau du foie ce qui justifie une surveillance hépatique régulière. Les métastases peuvent survenir dans l’uvée également le plus souvent l’uvée postérieure ou choroïde et sont plus fréquentes après cancer du sein ou du poumon. Les tumeurs conjonctivales peuvent être épithéliales (papillome bénins et carcinome épidermoïdes malins in situ ou invasifs) ou mélanocytaires (nævi bénins et mélanome More >

Abstract This paper proposes a novel artificial intelligence sythethized controller in the mechanical system which has high speed computation because of the LMI type criterion. The proposed membership functions are adopted and stabilization criterion of the closed-loop T-S fuzzy systems are obtained through a new parametrized LMI (linear matrix) inequality which is rearranged by machine learning membership functions.
