Chemiluminescence

Radioactive reagents have been gradually replaced by nonisotopic reagents for some tasks in molecular biology. Concern over laboratory safety and the economic and environmental aspects of radioactive waste disposal have been key factors in this change. Generally, the new nonisotopic systems have improved in terms of analytical sensitivity and the time required to obtain a result. The most prominent nonisotopic analytical methods exploit chemiluminescence, described here. This technique has been particularly effective when used in combination with an enzyme label, so that the amplifying properties of an enzyme label and the high sensitivity of a chemiluminescent detection reaction are combined to produce an ultrasensitive assay (e.g., chemiluminescent detection of peroxidase- and alkaline phos-phatase-labeled proteins and nucleic acid probes). In all of the commonly used applications in molecular biology, the analytical performance of the chemiluminescent systems approaches that of125I- or32P-based systems. Chemiluminescent systems also avoid the lengthy signal detection times required with32P-based methods, yielding results in minutes rather than days. In addition, chemiluminescent probes can be easily stripped from membranes, allowing the membranes to be reprobed many times without significant loss of resolution. Experimental protocols for directly attaching nonisotopic labels to nucleic acids and indirect labeling methods based on biotin, fluorescein, and digoxigenin labels are now well established. The ancillary reagents (e.g., avidin, streptavidin, antidigoxigenin, and antifluorescein enzyme conjugates) required for the indirect methods are widely available.

Enhanced chemiluminescence detection of glutathione based on isoluminol-PSM nanoparticles probe

In this paper, a new chemiluminescence (CL) strategy was constructed for the determination of physiological thiols by using an isoluminol labeled nano-probe. The amino group on the surface of the magnetic beads (MBs) were converted into pyridyl disulfide groups by treatment with N-succinimidyl-3-(2-pyridyldithio)propionate (SPDP), in the meantime, isoluminol and thiolated signal DNA were labeled on the surface of the polystyrene microspheres (PSMs). By treating the SPDP activated MBs with the modified PSMs, isoluminol molecules on the surface of the PSMs, along with the thiolated signal DNA, were attached to the surface of the MBs through disulfide bonds to form a CL probe. In the presence of glutathione (GSH), the disulfide bonds could be cleaved readily. The isoluminol molecules modified on the surface of the PSMs released from the CL probes were detached by magnetic separation and transferred to the dark closet for CL detection of isoluminol-H2O2-HRP system. Using GSH detection as a model, we prove a linear dose response in the range from 5¡Á10-10 to 8¡Á10-8 M. The detection limit of this trial for GSH determined is 5¡Á10-10 M. The proposed design was successfully applied to the extracts of K562 cell for intracellular thiols detection, the average amount of thiols was about 4.114¡Á10-13 M per K562 cell.

Data on human neutrophil activation induced by pepducins with amino acid sequences derived from beta2AR and CXCR4

The data described here is related to the research article titled (Gabl et al., 2016) [1]. Pepducins with peptide sequence derived from one of the intracellular domains of a given G-protein coupled receptor (GPCR) can either activate or inhibit cell functions. Here we include data on human neutrophil function induced by pepducins derived from beta2AR (ICL3-8) and CXCR4 (ATI-2341), respectively. ICL3-8 exerts neither direct activating effect on the NADPH-oxidase as measured by superoxide release nor inhibitory effect on FPR signaling. ATI-2341 dose-dependently triggers neutrophil activation and these cells were subsequently desensitized in their response to FPR2 specific agonists F2Pal10 and WKYMVM. Moreover, the ATI-2341 response is inhibited by PBP10 and the peptidomimetic Pam-(Lys-betaNSpe)6-NH2 (both are FPR2 specific inhibitors), but not to the FPR1 specific inhibitor cyclosporine H.

Lifestyle and Occupational Stress: A Potential Risk Factor for Obstructive Sleep Apnea in Nonobese Male Subjects

Purpose: To record the incidence of obstructive sleep apnea (OSA) in nonobese male subjects and investigate the coexistence of lifestyle stress, sleep deprivation, and upper airway inflammation. Materials and Methods: 552 patients were assessed during a survey of banks, government and corporate offices, recruitment agencies, and schools between January 2012 and January 2016. After applying the inclusion and exclusion criteria designed for this study, the number of patients tapered down to 120 patients who underwent diagnostic tests, viz. polysomnography, chemiluminiscence immunoassay, nephelometry, and upper airway endoscopy. This revealed the presence of OSA coexistent with elevated serum cortisol, C-reactive protein (CRP), and upper airway inflammation. Results: Polysomnography showed that 57 of 120 patients suffered from OSA. Objective evaluation of these patients exposed an undercurrent of lifestyle stress in 39 patients. CRP and serum cortisol were found to be significantly high (1.60 ¡À 0.52 and 7.20 ¡À 0.76 mug/dL, respectively) in 30 patients. Endoscopy revealed 18 patients with moderate, 7 with severe, and 5 with no upper airway inflammation. Conclusion: The results of this study demonstrated that OSA was found to be prevalent in the cohort of nonobese male patients studied. Coexistence of lifestyle stress, sleep deprivation, and upper airway inflammation was revealed.

Pathogen-mimicking nanocomplexes: self-stimulating oxidative stress in tumor microenvironment for chemo-immunotherapy

A novel drug-loaded pathogen-mimicking nanocomplex has been constructed for synergistic chemo-immunotherapy using detoxified lipopolysaccharide coated mesoporous silica nanoparticle. Detoxified lipopolysaccharide behaves as a dual-purpose entity that not only effectively mimics the function of the natural pathogen for triggering immune responses but also acts as a lid for inhibiting premature chemical drug release. In this approach, a knock-on effect would be observed at site of tumor: firstly, pathogen-mimicries elicited the elevated production of ROS; secondly, excessive production of ROS in turn oxidized the arylboronic ester to realize controlled chemotherapy; thirdly, in addition to inducing ROS generation, the nanocomplex would self-stimulate macrophages activation which subsequently activated cytotoxic T cells. Importantly, chemotherapy and immunotherapy were acting in a synergistic manner to inhibit solid tumor growth. Moreover, chemotherapeutic agents could be effectively released upon exposure to self-stimulating oxidative stress in which external addition of ROS was avoided. This proof of concept might open the door to a new generation of carrier materials in the field of cancer therapy.

A spectrophotometric method for the determination of aldehyde oxidase activity using 3-methyl-2-benzothiazolinone hydrazine: A preliminary study

Aldehyde oxidase, a molybdenum cofactor-containing cytosolic enzyme, is extensively distributed throughout the animal kingdom. The enzyme is mainly active in liver and other tissues of mammalian species and involved in the metabolism of wide range of aldehydes and nitrogen-containing molecules. A continuous spectrophotometric method for the quantitative determination of aldehyde oxidase, AO, enzyme activity is described in this article. This method is based on the coupling reaction between 3-methyl-2-benzothiazolinone hydrazone (MBTH) and the o-quinone. Dopamine as substrate for AO, is converted/oxidized to o-quinone. The latter react with MBTH to produce intensely colored products that absorb light maximally in the visible region. Then, AO activity has been kinetically characterized; the Km (Michaelis-Menten constant) and Vmax (maximum initial velocity) values for the oxidation of dopamine by AO were evaluated. The existence of MBTH in the reaction medium and production of stable color as well as the high epsilon values at 510 nm of MBTH-Q adduct make this direct technique more sensitive than other continuous methods for AO assay. The optimized MBTH reaction may be useful for biological staining of AO activity isolated from various biological sources in electrophoresis gels.

A New Linear Dichroism Approach for Determining Solute Orientations within Anionic Micelles

The building units of lyotropic nematic liquid crystals are weakly anisometric micelles.Their macroscopic orientation may be achieved by magnetic fields.The very sensitive liquid crystal linear dichroism (LCLD) technique may therefore be applied to study local preferred orientations and also solubilization sites of aromatic guest molecules within these nonspherical host micelles.The orientational information thus obtained may be directly transferred and utilized in chemically corresponding classical micellar solutions.This new approach to the study of micellar systems and their catalytic processes cannot be followed within classical spherical micelles because of the isotropy of their solutions.A model of solubilization is presented which allows orientational order parameters to be interpreted on a stereochemical basis.All the aromatic hydrocarbons reported in this paper tended to be preferentially oriented by “radical intercalation” modes within the host micelle.Heterocyclic nitrogens in the guest molecular frameworks drastically affected the preferred orientations.All these nitrogen-induced effects may be ascribed to strong specific grasping of the guest heterocyclic nitrogens at the polar micelle surface.
