A Novel Enzyme-Linked Immunosorbent Assay Procedure In One Hour By Pressure Incubation

Sprotocols
Authors: Pradip Nahar ### Abstract In this protocol, we describe a unique ELISA method for the detection of an antigen or antibody, in which ELISA steps are carried out by pressure incubation instead of conventional thermal incubation. Pressure-mediated ELISA (PELISA), carried out in 1 h shows more than a 2-fold increase in absorbance value than the control experiment carried out at the same time and temperature without applying pressure. Estimation of analyte by the 1-h...

Understanding the Combined Role of Internal and External Factors in New Service Development Process within the Professional Knowledge Intensive Business Service Firms

Our research asked the following main questions: how the characteristics of professionals service firms allow them to successfully innovate in exploiting through exploring by combining internal and external factors of innovation and how these ambidextrous organisations perceive these factors; and how do successful innovators in professional service firms use corporate entrepreneurship models in their new service development processes? With a goal to shed light on innovation in professional knowledge intensive business service firms’ (PKIBS), we...

Mental states monitoring through passive Brain-Computer Interface systems

The monitoring of cognitive functions aims at gaining information about the current cognitive state of the user by decoding brain signals. In recent years, this approach allowed to acquire valuable information about the cognitive aspects regarding the interaction of humans with external world. From this consideration, researchers started to consider passive application of brain–computer interface (BCI) in order to provide a novel input modality for technical systems solely based on brain activity. The objective of...

Code synchronization and interference management techniques for satellite navigation and communications

This thesis collects the outcomes of a Ph.D. course in Telecommunications engineering and it is focused on enabling techniques for Spread Spectrum (SS) navigation and communication satellite systems. It provides innovations for both interference management and code synchronization techniques. These two aspects are critical for modern navigation and communication systems and constitute the common denominator of the work. The thesis is organized in two parts: the former deals with interference management. We have proposed a...

La faccia nascosta di Hollywood: Tim Burton e il sublime

Lorenzo Bianchi
If you analyze Tim Burton’s filmography, the relationship between his entire work and the philosophical sublime could appear clear. First of all the use of darkness as the symbol of your inner being and also the concept of expressionism seen as the union between dark and light, shadows and brightness, the double nature of the sublime. Moreover, women in Tim Burton’s movies are savior angels, and the sublime is seen as the elevation of the...

Lucrezio interpreta Epicuro: Kant e il piacere, il sublime, la natura

Marco Beccalli

Da Bergson a Girard: il comico e il sacro

Andrea Grazioli
The essay by Claudio Rozzoni Il Riso di Molière. Teatro e impersonalità, which has been published in this magazine, examines the phenomenon of the comedian with particular emphasis on his/her impersonal nature. Starting from Henri Bergson’s ideas, and with particular and frequent reference to Molière’s theatre, Rozzoni takes a first step toward defining the air of impersonality that characterises comedy. The purpose of this work is to further explore the aforementioned idea. This study will...

Quantifying Chromogen Intensity In Immunohistochemistry Via Reciprocal Intensity.

Sprotocols
Authors: David Nguyen ### Abstract Immunohistochemistry is a routine procedure for detecting the expression of biological markers in formalin-fixed and paraffin-embedded tissues. Chromogens, which can appear as different colors (brown, blue, red) under bright field microscopy, are localized in fixed tissues to antigens of interest via an antibody-antigen detection system. The advantage of a chromogen system is that the stained tissue section is permanently fixed, and the staining quality is maintained for many years. The...

Multiplex Pcr For Amplifying Mitochondrial And Nuclear Products In Plants

Sprotocols
Authors: Magdalena Lütz & Noemí Colombo ### Abstract PCR amplification of a single copy nuclear region and a multicopy mitochondrial region together results in the competition between targets unequally represented in a single tube PCR reaction. This protocol allows a correct amplification of both products by adopting a sequential lay out of the PCR reaction which enhances the amplification of the nuclear gene in the first step and the mitochondrial gene in the final step....

Tandem Affinity Purification Of Remodeler-Mononucleosome Complexes For Chip-Seq In Mouse Embryonic Stem Cells

Sprotocols
Authors: Arnaud Depaux, Maud de Dieuleveult, Isabelle Hmitou, Sylvie Jounier, Hélène Humbertclaude & Matthieu Gerard ### Abstract This protocol describes a tandem affinity chromatin immunopurification strategy to analyze the distribution of chromatin remodelers onto the mouse genome. It is based on mouse embryonic stem (ES) cell lines that express, from the endogenous loci, remodelers fused with a tandem affinity purification (TAP)-tag. Two versions of the TAP-tag, introduced at the C terminus, have been used successfully:...

Obtaining Targeted Metagenomes From Uncultivated Environmental Synechococcus Using Flow Cytometry-Based Viral Tagging

Sprotocols
Authors: Li Deng, Bonnie T. Poulos & Matthew B. Sullivan ### Abstract Ocean viruses are abundant, ubiquitous, and play important roles in global biogeochemical cycles through mortality, horizontal gene transfer and manipulation of host metabolism. However, the ability to link viruses to their hosts in a high-throughput manner bottlenecks our ability to understand virus-host interactions in complex communities. Here, we present viral tagging (VT), a method that combines mixtures of isotope labeled host cells and...

Stereo-Separations Of Peptides By Capillary Electrophoresis And Chromatography

Sprotocols
Authors: Afzal Hussain, Iqbal Hussain, Mohamed F. Al-Ajmi & Imran Ali ### Abstract Small peptides (di-, tri-, tetra- penta- hexa etc. and peptides) control many chemical and biological processes. The biological importance of stereomers of peptides is of great value. The stereo-separations of peptides are gaining importance in biological and medicinal sciences and pharmaceutical industries. There is a great need of experimental protocols of stereo-separations of peptides. The various chiral selector used were polysaccharides, cyclodextrins,...

Assay For Quantitative Determination Of Cyp1A1 Enzyme Activity Using 7-Ethoxyresorufin As Standard Substrate (Erod Assay)

Sprotocols
Authors: Afshin Mohammadi-Bardbori ### Abstract The activity of the enzyme 7-ethoxy-resorufin-O-deethylase (EROD) has been extensively employed in biomonitoring studies of persistent organic pollutants (POPs) for more than a decade. Although the procedure is simple, convenient, sensitive and accurate. The cytochrome P450 monooxygenase 1A (CYP1A) is induced by several planar toxic compounds and endogenous chemicals, and the induction of this protein is often measured in terms of EROD activity. This protocol describes how to use EROD...

Fusion gene and matrix gene assays have been used...

Long-Term Co-Culture Of Primary Hepatocytes And Gfp-Heparg Cells For Investigations On Plasmodium Hypnozoites

Sprotocols
Authors: Laurent Dembélé, Jean-François Franetich, Audrey Lorthiois, Audrey Gego, Georges Snounou & Dominique Mazier ### Abstract The dormant liver stages, hypnozoites, of some malaria parasite species were not amenable to in vitro studies because primary hepatocyte cultures could not be maintained beyond 10-14 days. In this protocol we describe a co-culture system where primary simian hepatocyte could be maintained for a month or more through co-cultivation with an immortalised liver derived cell line, Hepa-RG. The...
