Abstract
SCOPE Proteolysis-resistant gliadin peptides are intensely investigated in biomedical research relates to celiac disease and gluten-related disorders. Herein, the first integrated supramolecular investigation of pepsin-digested gliadin peptides (p-gliadin) is presented in combination with its functional behavior in the Caco-2 cell line. METHODS AND RESULTS First, gliadins are degraded by pepsin at pH 3, and the physicochemical properties of p-gliadin are compared with gliadin. An integrated approach using interfacial, spectroscopic, and microscopic techniques reveals that the p-gliadin forms spontaneously soluble large supramolecular structures, mainly oligomers and fibrils, capable of binding amyloid-sensitive dyes. The self-assembly of p-gliadin starts at a concentration of 0.40 µg mL-1 . Second, the stimulation of Caco-2 cells with the p-gliadin supramolecular system is performed, and the mRNA expression levels of a panel of genes are tested. The experiments show that p-gliadin composed of supramolecular structures triggers significant mRNA up-regulation (p < 0.05) of pro-apoptotic biomarkers (ratio Bcl2/Bak-1), chemokines (CCL2, CCL3, CCL4, CCL5, CXCL8), and the chemokine receptor CXCR3. CONCLUSIONS This work demonstrates that p-gliadin is interfacial active, forming spontaneously amyloid-type structures that trigger genes in the Caco-2 cell line involved in recruiting specialized immune cells.

Abstract
Hemoglobin (Hb)-based oxygen carriers (HBOCs) present an alternative to red blood cells (RBCs) when blood is not available. However, the most widely used synthesis techniques have fundamental flaws, which may have contributed toward disappointing clinical application. Polymerized Hb contains a heterogeneous distribution of particle size and shape, while Hb encapsulation inside liposomes results in high lipid burden and low Hb content. Meanwhile, there are a variety of other nanoparticle synthetic techniques which, having found success as drug delivery vehicles, may be well suited to function as an HBOC. We synthesized desolvated Hb nanoparticles (Hb-dNPs) with diameters of approximately 250 nm by the controlled precipitation of Hb with ethanol. Oxidized dextran was found to be an effective surface stabilizing agent that maintained particle integrity. In vitro biophysical characterization showed a high-affinity oxygen delivery profile (P50 = 7.72 mm Hg), suggesting a potential for therapeutic use and opening a new avenue for HBOC research.

Abstract
For thousands of years, plants and their products have been used as the mainstay of medicinal therapy. In recent years, besides attempts to isolate the active ingredients of medicinal plants, other new applications of plant products, such as their use to prepare drug delivery vehicles, have been discovered. Nanobiotechnology is a branch of pharmacology that can provide new approaches for drug delivery by the preparation of biocompatible carrier nanoparticles (NPs). In this article, we review recent studies with four important plant proteins that have been used as carriers for targeted delivery of drugs and genes. Zein is a water-insoluble protein from maize; Gliadin is a 70% alcohol-soluble protein from wheat and corn; legumin is a casein-like protein from leguminous seeds such as peas; lectins are glycoproteins naturally occurring in many plants that recognize specific carbohydrate residues. NPs formed from these proteins show good biocompatibility, possess the ability to enhance solubility, and provide sustained release of drugs and reduce their toxicity and side effects. The effects of preparation methods on the size and loading capacity of these NPs are also described in this review.

Abstract
It is generally agreed that, in most cases, surfactants are required to obtain stable polymeric nanoparticle dispersions. Here, we report a method which can be used to produce surfactant free yet stable polymeric nanoparticle dispersions. This method is based on explored mechanism of selective solvation of nanoparticles and EPD (electron pair donor)/EPA (electron pair acceptor) complexes formed among solvent and nonsolvent molecules. Using polyimide P84 (copolyimide 3,3(') 4,4(')-benzophenone tetracarboxylic dianhydride and 80% methylphenylene diamine+20% methylene dianiline) as the model polymer, this mechanism was realized through a combined liquid-liquid phase separation and solvent/nonsolvent mixing technology. Surfactant-free polyimide nanoparticles (<100 nm) were produced. Experimental details and principles of this technology were given based on the ternary diffusion, the liquid-liquid phase separation and the advanced nucleation and growth theory. Two types of methods [denoted as the forward titration method and the backward titration (BT) method] were examined. It was found that the BT method is extremely helpful to prepare polyimide nanoparticles (<100 nm). As another important aspect, explored stabilization mechanism of the resultant nanoparticle dispersions was supported by the comparative experiments, implying that selective solvation of nanoparticles and EPD/EPA complexes may play key roles in stabilization.

Abstract
The pharmacological activity of serine protease inhibitors, potential drugs for the treatment of thrombosis, is often linked to the presence of amidine functions. With the aim of developing a suitable formulation for these compounds, inulin and inulin acetate associated or not with 1,12-dodecanedicarboxylic acid, were chosen to prepare microspheres. Using a coacervation method, these biocompatible polymers led to microspheres of about 0.5-5 microm. The encapsulation of a water-soluble model drug (E,E)-bis(amidinobenzylidene)cycloheptanone [(E,E)-BABCH] in these microspheres was studied. In this investigation, factorial designs were used to determine the joint influence of several variables (drug mass, speed and time of formulation stirring, centrifugation time) for an optimum encapsulation efficiency. Results revealed that encapsulation efficiency reached 65% whatever the nature of the biopolymer, by using a stirring time of 30 min, a high stirring speed and a centrifugation time of 15 min. (E,E)-BABCH release from microspheres was examined in an in vitro model. The profiles were characterized by three phases strongly dependent on the microspheres and the diacid association displayed a crucial role. With inulin and inulin acetate, the initial phase was a rapid 'drug burst'. Within the first 5 min, 58-62% of the drug were delivered. Microspheres of inulin acetate associated with 1,12-dodecanedicarboxylic acid, showed a slower release with only 32% of the drug delivered after 15 min. After a slow diffusion phase (33 h), an increasing rate until complete drug release was observed for 2.5 days.

Abstract
In this paper, biopolymer nanoparticles are studied, which unlike many synthetic carriers used for controlled release, are biocompatible and biodegradable systems. Gliadins nanoparticles are obtained by a desolvatation method, also known as drawning-out precipitation. These particles have been shown to be interesting as drug release systems for all-trans-retinoic acid. The aim of this paper was to study the influence of the polarity of different drugs on nanoparticle characteristics such as size and drug loading efficiency. Three drugs of three different polarities were studied: the hydrophobic Vitamin E (VE), the slightly polar mixture of linalool and of linalyl acetate (LLA) and the cationic amphiphilic benzalkonium chloride (BZC). This comparative work shows that the amount of the entrapped VE and LLA is higher than that of the cationic BZC, confirming a strong interaction between gliadins and apolar compounds, due to the apolarity of the proteins. This interaction results in a low diffusion coefficient and a partition coefficient in favour of gliadins, resulting in a low permeability coefficient. The drug release kinetics of two substances, LLA and BZC, are observed, in showing a burst effect, then a diffusion process, which can be modelled assuming that the particles are homogeneous spheres.

Abstract
Whey protein beads were successfully produced using a new emulsification/cold gelation method. The principle of this method is based on an emulsifying step followed by a Ca(2+)-induced gelation of pre-denatured (80 degreesC/30 min) whey protein. Beads are formed by the dropwise addition of the suspension into a calcium chloride (CaCl(2)) solution. IR results show that bead formation has a pronounced effect on the secondary structure of whey protein, which leads to the formation of intermolecular hydrogen-bonded beta-sheet structures. Their preparation conditions (CaCl(2) concentrations of 10, 15, and 20% (w/w)) influence their sphericity and homogeneity: an increase in CaCl(2) favors regular-shaped beads. The physicochemical and mechanical characterizations of beads were also carried out. Their properties, such as swelling, elasticity, deformability, and resistance at fracture, change according to pH levels (1.9, 4.5, and 7.5) and preparation conditions. Indeed, protein chain networks exhibit different behavior patterns with respect to their charge. Finally, bead degradation by enzymatic hydrolysis reveals that beads are gastroresistant and form good matrixes to protect fat-soluble bioactive molecules such as retinol, that have in vivo intestinal absorption sites. The experiment demonstrated the potential of whey protein beads to protect molecules sensitive (i.e., vitamins) to oxidation.
