Abstract
BACKGROUND According to the literature, eating disorders are an increasing problem for more than a quarter of people with Type 1 diabetes and they are associated with accentuated diabetic complications. The clinical outcomes in this group when given standard eating disorder treatments are disappointing. The Medical Research Council guidelines for developing complex interventions suggest that the first step is to develop a theoretical model. AIM To review existing literature to build a theoretical maintenance model for disordered eating in people with Type 1 diabetes. METHOD The literature in diabetes relating to models of eating disorder (Fairburn's transdiagnostic model and the dual pathway model) and food addiction was examined and assimilated. RESULTS The elements common to all eating disorder models include weight/shape concern and problems with mood regulation. The predisposing traits of perfectionism, low self-esteem and low body esteem and the interpersonal difficulties from the transdiagnostic model are also relevant to diabetes. The differences include the use of insulin mismanagement to compensate for breaking eating rules and the consequential wide variations in plasma glucose that may predispose to 'food addiction'. Eating disorder symptoms elicit emotionally driven reactions and behaviours from others close to the individual affected and these are accentuated in the context of diabetes. CONCLUSION The next stage is to test the assumptions within the maintenance model with experimental medicine studies to facilitate the development of new technologies aimed at increasing inhibitory processes and moderating environmental triggers.

Abstract
This work reports on the coupling of antibody-functionalized micromotors and microwire-tagged proteins for rapid and multiplexed immunoassays. While micromotor-induced mixing accelerates the immunoreaction, tagging the proteins with microscopic particles of different sizes and shapes allows for their multiplexed discrimination, alerting of the presence of a biological threat.

Abstract
Monodispersed poly(styrene-co-N,N'-dimethylaminoethyl methacrylate) nanoparticles (P(St-co-DMAEMA) NPs) were synthesized by emulsion polymerization. Zeta potential, volume swelling ratio and in vitro release of fluorescer coumarin-6 from the NPs were determined in buffer of various pH. With an optimized formulation, the diameter of NPs is 100 nm approximately and the polydispersity index (PI) is less than 0.1. The NPs have a hydrophilic surface and alterable surface charge which is almost neutral at normal physiological pH, but becomes much more positive under acidic conditions. The volume swelling ratios and in vitro release of coumarin-6 are highly dependent on pH, which are significantly increased at the lower pH and higher DMAEMA/St molar ratio. More than 70% of the loaded coumarin-6 could be released in 24 h at pH2, which is 2.3-folds higher than that at normal physiological pH. The P(St-co-DMAEMA) NPs show promising applications to targeted drug delivery to tumors.

Abstract
Monodispersed soap-free poly(MMA-EA-AA) latex particles with surface carboxyl groups were synthesized by emulsion polymerization of methyl methacrylate (MMA), ethyl acrylate (EA) and acrylic acid (AA) in aqueous medium, and streptomycin sulfate (SMS) was immobilized onto these particles using three different methods. A model experiment was designed to test the feasibility of the reaction between the carboxyl groups of polymer and the amino groups of the medicine. The covalent coupling between the latex particles and the medicine was confirmed by XPS. Results showed that the medicine molecules were located on the particle surface after immobilization, and the coupling efficiency of SMS in pre-adsorption method was higher than that in direct method. The highest coupling efficiency of this medicine was achieved using the spacer-arm method. It was demonstrated that the immobilized medicine had similar antimicrobial activity as the free form using Escherichia coli as an evaluating organism.
