Abstract
Hemorrhage syndrome is one of the most prevalent and epidemic diseases that is mainly caused by Aeromonas hydrophila invasion in Megalobrama amblycephala. Recent studies have uncovered a number of immune enzymes and transcripts that are differently expressed in this disease, but the molecular mechanism elicited still remain largely unknown. Here, we constructed an in vivo A. hydrophila infection to investigate the immune mechanism in M. amblycephala using comparative proteomic approach at the one day after infection. 30 altered protein spots were found to undergo differential expression against A. hydrophila infection in the hepatopancreas of M. amblycephala based on 2-DE and were all successfully identified using MALDI-TOF/TOF, representing 18 unique proteins. These proteins were functionally classified into metabolism, antioxidant, cofactors and vitamins, chaperone and signal transduction. Network interaction and Gene Ontology annotation indicated 13 unique proteins were closely related to immune response and directly regulated by each other. Compared with the control group, A. hydrophila infection significantly decreased the metabolism-related mRNA expressions of ENO3, APOA1, CAT and FASN, but increased the mRNA expressions of MDH, ALDOB and RSP12, which was consistent with the protein expression. Nevertheless, FAH was down-regulated at both levels but had no significant difference in mRNA level, ALDH8a1 was down-regulated at protein level but non-significantly up-regulated at the mRNA level. GSTm was up-regulated at protein level but down-regulated at the mRNA level. Consequently, these results revealed that A. hydrophila infection altered the related antioxidative proteins via complex regulatory mechanisms and reduced the immune ability of M. amblycephala at the one day after infection.

Abstract
Ionic liquids (ILs) have advanced a variety of applications, including matrix-assisted laser desorption/ionization-mass spectrometry (MALDI-MS). ILs can be used as matrices and solvents for analyte extraction and separation prior to analysis using laser desorption/ionization-mass spectrometry (LDI-MS). Most ILs show high stability with negligible sublimation under vacuum, provide high ionization efficiency, can be used for qualitative and quantitative analyses with and without internal standards, show high reproducibility, form homogenous spots during sampling, and offer high solvation efficiency for a wide range of analytes. Ionic liquids can be used as solvents and pseudo-stationary phases for extraction and separation of a wide range of analytes, including proteins, peptides, lipids, carbohydrates, pathogenic bacteria, and small molecules. This review article summarizes the recent advances of ILs applications using MALDI-MS. The applications of ILs as matrices, solvents, and pseudo-stationary phases, are also reviewed.

Abstract
In this study, a series of magnetic ionic liquids (MILs) were investigated for the extraction and preconcentration of bacteria from aqueous samples. By dispersing small volumes (e.g., 15 μL) of MIL within an aqueous cell suspension, bacteria were rapidly extracted and isolated using a magnetic field. Of the seven hydrophobic MILs examined, the trihexyl(tetradecyl)phosphonium Ni(II) hexafluoroacetylacetonate ([P66614+][Ni(hfacac)3-]) MIL exhibited the greatest enrichment of viable Escherichia coli K12 when coupled with microbiological culture as the detection method. The MIL-based strategy was applied for the preconcentration of E. coli from aqueous samples to obtain enrichment factors (E F) as high as 44.6 in less than 10 min. The MIL extraction approach was also interfaced with polymerase chain reaction (PCR) amplification where the positive detection of E. coli was achieved with the [P66614+][Co(hfacac)3-], [P66614+][Ni(hfacac)3-], [P66614+][Dy(hfacac)4-], and [P66614+][Nd(hfacac)4-] MILs. While direct sampling of an aqueous cell suspension at a concentration of 1.68 × 104 colony-forming units (CFUs) mL-1 yielded no amplicon when subjected to PCR, extraction of the sample with the [P66614+][Ni(hfacac)3-] MIL under optimized conditions provided sufficient enrichment of E. coli for amplicon detection. Importantly, the enrichment of bacteria using the Ni(II)-, Co(II)-, and Dy(III)-based MILs was compatible with real-time quantitative PCR amplification to dramatically improve sample throughput and lower detection limits to 1.0 × 102 CFUs mL-1. The MIL-based method is much faster than existing enrichment approaches that typically require 24-h cultivation times prior to detection and could potentially be applied for the preconcentration of a variety of Gram-negative bacteria from aqueous samples. Graphical abstract Magnetic ionic liquid solvents rapidly preconcentrate viable E. coli cells for unambiguous pathogen detection using microbiological culture and qPCR.

Abstract
Ionic liquids (ILs) are entirely composed of ions and they possess fascinating properties, including low volatility, tunable viscosity, miscibility and electrolytic conductivity, which make them promising alternatives to traditional organic solvents used in sample preparation. The recent surge in the number of publications clearly indicates an increasing interest of the analytical and bioanalytical community toward these exciting and unique solvents. This article highlights the recent advances in the use of ILs as extraction solvents, as materials for separation and preconcentration in chromatographic techniques, and as matrices in mass spectrometric techniques for bioassays in biocomplex samples. We also briefly discuss the potential applications of ILs in biocatalysis.

Abstract
Identifying trace amounts of bacteria rapidly, accurately, selectively, and with high sensitivity is important to ensuring the safety of food and diagnosing infectious bacterial diseases. Microbial diseases constitute the major cause of death in many developing and developed countries of the world. The early detection of pathogenic bacteria is crucial in preventing, treating, and containing the spread of infections, and there is an urgent requirement for sensitive, specific, and accurate diagnostic tests. Matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS) is an extremely selective and sensitive analytical tool that can be used to characterize different species of pathogenic bacteria. Various functionalized or unmodified nanomaterials can be used as affinity probes to capture and concentrate microorganisms. Recent developments in bacterial detection using nanomaterials-assisted MALDI-MS approaches are highlighted in this article. A comprehensive table listing MALDI-MS approaches for identifying pathogenic bacteria, categorized by the nanomaterials used, is provided.

Abstract
Ionic liquids (ILs) are room-temperature molten salts that have applications in both physical sciences and more recently in the purification of proteins and lipids, gene transfection and sample preparation for electron microscopy (EM) studies. Transfection of genes into cells requires membrane fusion between the cell membrane and the transfection reagent, thus, ILs may be induce a membrane fusion event. To clarify the behavior of ILs with cell membranes the effect of ILs on model membranes, i.e., liposomes, were investigated. We used two standard ILs, 1-ethyl-3-methylimidazolium lactate ([EMI][Lac]) and choline lactate ([Ch][Lac]), and focused on whether these ILs can induce lipid vesicle fusion. Fluorescence resonance energy transfer and dynamic light scattering were employed to determine whether the ILs induced vesicle fusion. Vesicle solutions at low IL concentrations showed negligible fusion when compared with the controls in the absence of ILs. At concentrations of 30% (v/v), both types of ILs induced vesicle fusion up to 1.3 and 1.6 times the fluorescence intensity of the control in the presence of [Ch][Lac] and [EMI][Lac], respectively. This is the first demonstration that [EMI][Lac] and [Ch][Lac] induce vesicle fusion at high IL concentrations and this observation should have a significant influence on basic biophysical studies. Conversely, the ability to avoid vesicle fusion at low IL concentrations is clearly advantageous for EM studies of lipid samples and cells. This new information describing IL-lipid membrane interactions should impact EM observations examining cell morphology.

Ceria nanocubic-ultrasonication assisted dispersive liquid-liquid microextraction coupled with matrix assisted laser desorption/ionization mass spectrometry for pathogenic bacteria analysis. Talanta 2013; 120:208-17.

Abstract
A new ceria (CeO2) nanocubic modified surfactant is used as the basis of a novel nano-based microextraction technique for highly sensitive detection of pathogenic bacteria (Pseudomonas aeruginosa and Staphylococcus aureus). The technique uses ultrasound enhanced surfactant-assisted dispersive liquid-liquid microextraction (UESA-DLLME) with and without ceria (CeO2) followed by matrix assisted laser desorption/ionization mass spectrometry (MALDI-MS). In order to achieve high separation efficiency, we investigated the influential parameters, including extraction time of ultrasonication, type and volume of the extraction solvent and surfactant. Among various surfactants, the cationic surfactants can selectively offer better extraction efficiency on bacteria analysis than that of the anionic surfactants due to the negative charges of bacteria cell membranes. Extractions of the bacteria lysate from aqueous samples via UESA-DLLME-MALDI-MS were successfully achieved by using cetyltrimethyl ammonium bromide (CTAB, 10.0 µL, 1.0×10(-3) M) as surfactants in chlorobenzene (10.0 µL) and chloroform (10.0 µL) as the optimal extracting solvent for P. aeruginosa and S. aureus, respectively. Ceria nanocubic was synthesized, and functionalized with CTAB (CeO2@CTAB) and then characterized using transmission electron microscopy (TEM) and optical spectroscopy (UV and FTIR). CeO2@CTAB demonstrates high extraction efficiency, improve peaks ionization, and enhance resolution. The prime reasons for these improvements are due to the large surface area of nanoparticles, and its absorption that coincides with the wavelength of MALDI laser (337 nm, N2 laser). CeO2@CTAB-based microextraction offers lowest detectable concentrations tenfold lower than that of without nanoceria. The present approach has been successfully applied to detect pathogenic bacteria at low concentrations of 10(4)-10(5) cfu/mL (without ceria) and at 10(3)-10(4) cfu/mL (with ceria) from bacteria suspensions. Finally, the current approach was applied for analyzing the pathogenic bacteria in biological samples (blood and serum). Ceria assist surfactant (CeO2@CTAB) liquid-liquid microextraction (LLME) offers better extraction efficiency than that of using the surfactant in LLME alone.

Abstract
The heat stress response of Escherichia coli at various temperatures has been investigated using NiO nanoparticles assisted MALDI-TOF-MS. Significant numbers of protein peaks were obtained in the presence of NiO NPs when the samples were incubated at various temperatures in comparison with the control E. coli suspension (10(7)cfu/mL). The 10 kDa chaperonin (groES) is the principal protein operating both for the protection of proteins from denaturation and in the assembly of newly synthesized proteins. During the heat stress response with NiO NPs, 10 kDa chaperonin (grosES) proteins were detected using MALDI-TOF MS. The viability of E. coli was checked on LB agar plates at different temperatures and time treatments. In the presence of NiO NPs, viability decreases drastically; this has been explored and correlated with the MALDI-TOF MS results. Further, surface morphological changes of E. coli at different temperatures were investigated with NiO NPs by transmission electron microscopy (TEM). The response of heat stress toward E. coli for generating more stable protein ions can be applied for bacterial detection under high temperature conditions from biological, clinical and environmental samples.

Abstract
The introduction of nanoparticles into mass spectrometric research greatly influenced the applicability of this technique into various omics. Surface-modified or functionalized nanoparticles (NPs) have recently extended the use of mass spectrometry into microorganism research. We survey the application of unmodified NPs, for microorganism research, on the basis of our expertise in this area within the recent years in this decade. The use of unmodified NPs in mass spectrometry, especially with respect to microorganisms, is an untreaded research area, which we have ventured to probe and have been fruitful. On the basis of our experience, we provide an insight into the principle behind the use of unmodified NPs and provide guidelines to be followed to obtain significant results. We also brief the current scenario of nanoparticle interaction-assisted laser desorption/ionization mass spectrometry (NPILDI-MS) for rapid, simple, direct and sensitive detection of microorganisms on the basis of our past and present reports, quoting examples of successful application of this technique. Finally, we address the future of the NPILDI-MS technique and the tools needed to reach those visions.

This study demonstrates the first use of matrix assisted laser desorption/ionization mass spectrometry (MALDI-MS) to trace the Invivo infection kinetics of the well known deadly pathogen Staphylococcus aureus in Swiss albino mice. The growth curve of the bacteria from the point of injection (200μL of bacterial suspension (10(8)cfu/mL)) into the mouse blood till mortality (death) was periodically analyzed using the plate counting method and MALDI-MS. Bacterial counts of 10(3)cfu/mL were observed in the log phase of the growth curve in the blood and 10(2)cfu/mL were observed in the urine samples. Death occurred in the log phase of the growth curve, where the bacterial counts showed steady increase. In other cases, the bacteria counts started decreasing after 48h and by 96h the bacteria got totally eliminated from the mouse and these mice survived. Direct MALDI-MS was not feasible for tracking the bacteria in the infected blood. However, ionic liquid 1-Butyl-3-methylimidazolium tetrafluoroborate was successful in enabling bacterial detection amidst the strong blood peaks. But, in the case of the urine analysis, it was observed that direct MALDI-MS was adequate to enable detection. The results obtained prove the efficacy of MALDI-MS for analyzing pathogenic bacteria in clinical samples. This article is part of a Special Issue entitled: Proteomics: The clinical link.
