“…26,29 In this work, sulfobetaine methacrylate (SBMA) and carboxybetaine methacrylate (CBMA) were chosen as potential photograftable monomers due to their excellent anti-fouling properties including ultra-low protein adsorption and cell adhesion as reported elsewhere. 30,31 SBMA and CBMA contain a methacrylate group which can be polymerized through a radical chain polymerization mechanism. To engineer a durable zwitterionic cross-linked zwitterionic hydrogel coating, poly(ethylene glycol) diacrylate (PEGDA, MW 575), a crosslinking molecule, was incorporated into the formulation.…”

The foreign body response (FBR) to implantable materials can negatively impact performance of medical devices such as the cochlear implant. Engineering surfaces that resist the FBR could lead to enhanced functionality including potentially improving outcomes for cochlear implant recipients through reduction in fibrosis. In this work, we coat poly(dimethylsiloxane) (PDMS) surfaces with two zwitterionic polymers, poly(sulfobetaine methacrylate) (pSBMA) and poly(carboxybetaine methacrylate) (pCBMA), using a simultaneous photografting/photo-cross-linking process to produce a robust grafted zwitterionic hydrogel. reduce nonspecific protein adsorption, the first step of the FBR. The coating process uses benzophenone, a photografting agent and type II photoinitiator, to covalently link the cross-linked zwitterionic thin film to the PDMS surface. As the concentration of benzophenone on the surface increases, the adhesive strength of the zwitterionic thin films to PDMS surfaces increases as determined by shear adhesion. Additionally, with increased concentration of the adsorbed benzophenone, failure of the system changes from adhesive delamination to cohesive failure within the hydrogel, demonstrating that durable adhesive bonds are formed from the photografting process. Interestingly, antifouling properties of the zwitterionic polymers are preserved with significantly lower levels of nonspecific protein adsorption on zwitterion hydrogel-coated samples compared to uncoated controls. Fibroblast adhesion is also dramatically reduced on coated substrates. These results show that cross-linked pSBMA and pCBMA hydrogels can be readily photografted to PDMS substrates and show promise in potentially changing the fibrotic response to implanted biomaterials.

“…The Pareto solution set is always of utmost important in the multiple-objective optimization. Aiming at the Pareto solution set of multiple-objective optimization, the weight analysis methods are mainly adopted in structural optimization such as those presented in [1][2][3][4][5][6][7][8][9][10]. The idea that the weight is related to the slope of the Pareto curve in the objective space in a way that an even spread of Pareto points actually corresponds to often very uneven distributions of weights has been proposed [1].…”

Multiple optimization objectives and the Pareto set often arise from engineering structural optimization. Normalization methods (such as the weighting method) have the disadvantage that the weighted value is not set by the decision maker but the designer and is greatly influenced by the opinion of the designer. On this basis, in this paper a non-dominated sorting genetic algorithm-analytic hierarchy process (NSGA-AHP) method is proposed for decision making and analysis of the Pareto solution set of the multiple-objective optimization in a structural optimal model. In addition, illustrated by the example of a disc brake, a multiple-objective optimization model for a disc brake has been here developed. Besides, the NSGA-AHP method is adopted for the analysis optimization. The research results show that the NSGA-AHP method can be utilized to select the Pareto solution set in an effective way and that this method is effective in solving a multiple-objective problem in the structural optimization design.

The antioxidant and anti-inflammatory properties of Citrus flavonoids can play a key role in their activity against several degenerative diseases and particularly brain diseases. In Brazil promising studies deposited in the patents "pharmaceutical formulation" form was obtained from the inclusion of Citrus sinensis L. (orange) essential oil with β-cyclodextrin and Citrus limon (lemon) compounds and their applications in therapy of Alzheimer's disease. In this chapter, we report activities of active compounds present in the genus Citrus, which include antioxidant, anti-inflammatory, anxiolytic, insecticidal, and anticholinesterase activities. These activities are associated with some neurodegenerative diseases such as Alzheimer's disease (AD). Pharmaceutical formulations containing such compounds (for example, inhibitors such as acetylcholinesterase (AChE) of C. limon (5,8-dimethoxy-psoralen and 5,7-dimethoxycumarin) and essential oil from C. sinensis oils are reported in this chapter. These results indicate that the effects of the essential oil and substances of Citrus species are very interesting for further isolation of AChE inhibitors that can be used in the formulation of natural products for neurodegenerative diseases.
