Abstract
Advances in nanoparticle-based systems constitute a promising research area with important implications for the treatment of bacterial infections, especially against multidrug resistant strains and bacterial biofilms. Nanosystems may be useful for the diagnosis and treatment of viral and fungal infections. Commercial diagnostic tests based on nanosystems are currently available. Different methodologies based on nanoparticles (NPs) have been developed to detect specific agents or to distinguish between Gram-positive and Gram-negative microorganisms. Also, biosensors based on nanoparticles have been applied in viral detection to improve available analytical techniques. Several point-of-care (POC) assays have been proposed that can offer results faster, easier and at lower cost than conventional techniques and can even be used in remote regions for viral diagnosis. Nanoparticles functionalized with specific molecules may modulate pharmacokinetic targeting recognition and increase anti-infective efficacy. Quorum sensing is a stimuli-response chemical communication process correlated with population density that bacteria use to regulate biofilm formation. Disabling it is an emerging approach for combating its pathogenicity. Natural or synthetic inhibitors may act as antibiofilm agents and be useful for treating multi-drug resistant bacteria. Nanostructured materials that interfere with signal molecules involved in biofilm growth have been developed for the control of infections associated with biofilm-associated infections.

Abstract
Some luminol imide derivatives with different substituent groups have been designed and synthesized. Their electrochemiluminescence properties have been measured with a view to developing new biosensors. The ECL response to hydrogen peroxide in the presence of these luminescent derivatives has been investigated taking into account crucial factors such as the applied potential value, injection volume of hydrogen peroxide, and the substituent groups in molecular structures. The experimental data demonstrated that the substituent groups in these imide derivatives can have a profound effect upon the ECL abilities of these studied compounds. The present research work affords new and useful exploration for the design and development of new soft matter for ECL biosensors with luminol functional groups.

Abstract
A novel cholesterol biosensor was prepared based on gold nanoparticles-catalyzed luminol electrogenerated chemiluminescence (ECL). Firstly, l-cysteine-reduced graphene oxide composites were modified on the surface of a glassy carbon electrode. Then, gold nanoparticles (AuNPs) were self-assembled on it. Subsequently, cholesterol oxidase (ChOx) was adsorbed on the surface of AuNPs to construct a cholesterol biosensor. The stepwise fabrication processes were characterized with cyclic voltammetry and atomic force microscopy. The ECL behaviors of the biosensor were also investigated. It was found that AuNPs not only provided larger surface area for higher ChOx loading but also formed the nano-structured interface on the electrode surface to improve the analytical performance of the ECL biosensor for cholesterol. Besides, based on the efficient catalytic ability of AuNPs to luminol ECL, the response of the biosensor to cholesterol was linear range from 3.3 μM to 1.0 mM with a detection limit of 1.1 μM (S/N=3). In addition, the prepared ECL biosensor exhibited satisfying reproducibility, stability and selectivity. Taking into account the advantages of ECL, we confidently expect that ECL would have potential applications in biotechnology and clinical diagnosis.

Maintenance dosing for sublingual immunotherapy by prominent European allergen manufacturers expressed in bioequivalent allergy units. Ann Allergy Asthma Immunol 2011; 107:448-458.e3.

Abstract
BACKGROUND Sublingual immunotherapy (SLIT) has become established in Europe, and its efficacy is being evaluated in the United States. The doses used for SLIT in Europe today are difficult to evaluate, because each manufacturer expresses the potency of its extracts differently. OBJECTIVES To compare in vitro European SLIT maintenance solutions against US licensed standardized allergenic extract concentrates and to determine the monthly SLIT doses delivered expressed in bioequivalent allergy units ([B]AU). METHODS We studied Dermatophagoides pteronyssinus, timothy grass pollen, cat (hair) and short ragweed pollen allergen extracts. The SLIT maintenance solutions of 4 leading European manufacturers and standardized concentrate extracts of 3 US manufacturers were analyzed with the following assays: protein content, relative potency (immunoglobulin E [IgE]-binding enzyme-linked immunosorbent assay [ELISA] inhibition) and major allergen content. The relative monthly allergen dose in (B)AU was calculated for each recommended SLIT schedule. RESULTS Relative potency was approximately 10 times higher for US concentrate standardized extracts-which are meant to be diluted-than for European SLIT maintenance solutions of D pteronyssinus and timothy grass pollen. For cat (hair) and short ragweed pollen, the difference was less. Measurements of relative potency and major allergen content correlated well. In our assays, European mite extracts contain a very low quantity of Der p 2 compared with US mites. CONCLUSION Recommended SLIT doses in Europe vary widely among the manufacturers, but are consistently lower (Eur1) or higher (Eur4) over all four allergens tested. SLIT efficacy probably depends on additional factors apart from the exact dose. SLIT dose finding studies should be done for each product.

Abstract
Aiming at developing cyanobacterial-based biosensors for heavy metal detection, expression of heavy metal inducible genes of the cyanobacterium Synechocystis PCC 6803 was investigated by quantitative RT-PCR upon 15 minutes exposure to biologically relevant concentrations of Co2+, Zn2+, Ni2+, Cd2+, Cr6+, As3+ and As5+. The ziaA gene, which encodes a Zn2+-transporting P-type ATPase showed a markedly increased mRNA level after incubation with Cd2+ and arsenic ions, besides the expected induction by Zn2+ ions. The Co2+ efflux system-encoding gene coaT was strongly induced by Co2+ and Zn2+ ions, moderately induced by As3+ ions, and induced at a relatively low level by Cd2+ and As5+ ions. Expression of nrsB, which encodes a part of a putative Ni2+ efflux system was highly induced by Ni2+ salts and at a low extent by Co2+ and Zn2+ salts. The arsB gene, which encodes a putative arsenite-specific efflux pump was highly induced by As3+ and As5+ ions, while other metal salts provoked insignificant transcript level increase. The transcript of chrA, in spite of the high sequence similarity of its protein product with several bacterial chromate transporters, shows no induction upon Cr6+ salt exposure. We conclude that due to the largely unspecific heavy metal response of the studied genes only nrsB and arsB are potential candidates for biosensing applications for detection of Ni2+ and arsenic pollutants, respectively.

Abstract
The gene expression plasmid pMALU5 for the fusion protein of protein A (SpA) with a complete sequence of firefly luciferase (Luc) was constructed. The fused gene was expressed in Escherichia coli, and the resulting SpA-Luc fusion protein was purified by one-step affinity chromatography on IgG-Sepharose. The protein retained both activities: IgG binding capability of protein A and enzymatic activity of luciferase. Blotting analyses were performed with the fusion protein to determine a tumor marker of alpha-fetoprotein (AFP). AFP was detected at the lowest detection limit of 5 pg by dot blotting and Western blotting. The SpA-Luc fusion protein provides a highly selective, sensitive, and versatile marker for blotting analyses.

Abstract
Firefly luciferase (Photinus pyralis) was fused with a histidine tag and a biotin carboxyl carrier protein (BCCP) domain at its amino terminus. Highly purified recombinant luciferase was obtained by a one-step purification protocol, utilizing immobilized metal affinity chromatography. The novel BCCP-luciferase had properties, stability, and activity similar to those of native luciferase. The biotin molecule on the BCCP domain allowed specific immobilization of BCCP-luciferase on avidin-coated surfaces via the biotin-avidin interaction.

Abstract
This review discusses current developments in biosensors for toxic materials of defence interest with particular emphasis on the biological element of such devices. A wide variety of synthetic chemicals, toxins of plant or animal origin and biological materials--including various disease micro-organisms as well as some bacterial exotoxins--have either been used as warfare agents or are perceived as having the potential to be used for that purpose. Although an enormous effort is being put into developing biosensors, relatively few analytes, especially toxic materials, can yet be measured by commercially available devices. The factors which currently mitigate against the use of enzyme, natural receptor or antibody based biosensors for unattended continuous environmental monitoring of toxic materials include the inherent instability and availability of suitable proteins and--for receptors and antibodies--the essentially irreversible nature of the binding event, which necessitates a continuous supply of reagents for sequential measurements. Assays involving antibody or DNA based biosensors are time consuming when working in a hazardous environment. Nevertheless, biosensors are capable of being used for extremely sensitive and specific on-site measurements of contamination by specific toxic materials. Methods for improving the stability, extending the range and altering the binding characteristics of sensing molecules are discussed.

Abstract
Chemiluminescent measurement of cholesterol can be performed in various biological tissues and fluids. The method described in this study has a sensitivity of 54 pmol. The tissue samples used for the determination of cholesterol can be reduced to as little as 1 mg and assay can be performed on diluted biological fluids, allowing sampling of plasma or serum as little as 5 microliters. Cholesterol is solubilized in sodium cholate and aliquots are added to a reaction mixture containing cholesterol oxidase, luminol and peroxidase. Cholesterol oxidase, in the presence of cholesterol yields H2O2 which produces light in presence of luminol and peroxidase. Emitted light is quantified at a wavelength of 420 nm by means of a photomultiplier. Optimal conditions of the assay were determined and examples of cholesterol determinations, in blood plasma and nervous tissues, are presented.
