SANIST: optimization of a technology for compound identification based on the European Union directive with applications in forensic, pharmaceutical …
2016
Electrospray Ionization and collision induced dissociation tandem mass spectrometry are usually employed to obtain compound identification through a mass spectra match. Different algorithms have been developed for this purpose (for example the nist match algorithm). These approaches compare the tandem mass spectra of the unknown analyte with the tandem mass spectra spectra of known compounds inserted in a database. The compounds are usually identified on the basis of spectral match value associated with a probability of recognition. However, this approach is not usually applied to multiple reaction monitoring transition spectra achieved by means of triple quadrupole apparatus, mainly due to…
Principles and Elements of Risk Management – Data and Initial Conditions
2014
This chapter is devoted to furnishing background information on Risk Management, explaining the string of steps that comprise it, and the use of techniques within it, as well as their relationships. The chapter follows the widely accepted sequence for risk identification, assessment, execution, remediation and control; it starts with some basic definitions and, in its first topic, analyzes the sources for risks, considering internal and external risks and opportunities. It follows with a guide for identifying and managing risks in different areas of a project and suggests appropriate tools and techniques for each one. Completion of sequence sensitivity analysis, a subject developed in full …
Microbial Diversity in the Midguts of Field and Lab-Reared Populations of the European Corn Borer Ostrinia nubilalis
2011
Background: Insects are associated with microorganisms that contribute to the digestion and processing of nutrients. The European Corn Borer (ECB) is a moth present world-wide, causing severe economical damage as a pest on corn and other crops. In the present work, we give a detailed view of the complexity of the microorganisms forming the ECB midgut microbiota with the objective of comparing the biodiversity of the midgut-associated microbiota and explore their potential as a source of genes and enzymes with biotechnological applications. Methodological/Principal Findings: A high-throughput sequencing approach has been used to identify bacterial species, genes and metabolic pathways, parti…
The use of reflection-card by elite youth basketball players, head coach and team manager : effects on players’ performance and perceptions of users
2017
AbstractThe purpose of the present paper was to test the effectiveness of the r-cards in sport performance, and to examine what kind of benefits and challenges the head coach, team manager and female basketball players (N = 12) faced when using the r-cards. Mixed methods were employed to gather specific data to answer the research questions. Inferential statistical analyses were conducted to examine whether players’ performances in terms of their targeted defensive rebound percentage and free-throw percentage differed across the five matches played. No significant differences were found. However, evidence from the qualitative data provides a contrasting but insightful perspective. Subjectiv…
The neuronal ceroid-lipofuscinoses: A historical introduction
2013
AbstractThe neuronal ceroid-lipofuscinoses (Batten disease) collectively constitute one of the most common groups of inherited childhood onset neurodegenerative disorders, and have also been identified in many domestic and laboratory animals. The group of human neuronal ceroid-lipofuscinoses currently comprises 14 genetically distinct disorders, mostly characterised by progressive mental, motor and visual deterioration with onset in childhood or adolescence. Abnormal autofluorescent, electron-dense granules accumulate in the cytoplasm of nerve cells, and this storage process is associated with selective destruction and loss of neurons in the brain and retina. The present paper outlines near…
Battery Models for Battery Powered Applications: A Comparative Study
2020
Battery models have gained great importance in recent years, thanks to the increasingly massive penetration of electric vehicles in the transport market. Accurate battery models are needed to evaluate battery performances and design an efficient battery management system. Different modeling approaches are available in literature, each one with its own advantages and disadvantages. In general, more complex models give accurate results, at the cost of higher computational efforts and time-consuming and costly laboratory testing for parametrization. For these reasons, for early stage evaluation and design of battery management systems, models with simple parameter identification procedures are…
A new classification of the South African endemic family Bruniaceae based on molecular and morphological data
2011
The classification of Bruniaceae is reviewed based on molecular (matK, ITS, rbcL) and morphological data, and the tribes and genera are redefined as monophyletic, morphologically diagnosable lineages. The family is subdivided into three tribes and six genera with 81 accepted species, Linconieae (Linconia), Audouinieae {Audounia [inch Tittmannia', Thamnea [incl. Pseudobaeckea teres]), and Brunieae (Berzelia [inch Brunia p.p.], Staavia [incl. Raspalia staavioides], and Brunia [incl. Nebelia, Pseudobaeckea p.p., Raspalia p.p., Lonchostoma, Mniothamned'). A key for the new classification, a short description of each genus and an updated nomenclature of all the species are provided. Two new trib…
QUALITATIVE AND QUANTITATIVE BEHAVIORAL TRAITS IN A COMMUNITY OF FURCOCERCARIAE TREMATODES: TOOLS FOR SPECIES SEPARATION?
2008
Many trematode cercariae show distinct behavioral features, which have commonly been used in species identification in combination with morphological characteristics. However, information regarding cercariae behavior has often not been quantified in detail, or it is scattered in the literature, which is why the appropriate level of precision in behavioral identity, particularly in groups of cercariae species showing considerable morphological overlap, has not been properly established. In this study, we investigated one such group, the furcocercariae trematodes, by studying their behavior in a community consisting of 8 species (Diplostomum pseudospathaceum, Ichthyocotylurus variegatus, Coty…

Differential Proteomics Based on 2D-Difference In-Gel Electrophoresis and Tandem Mass Spectrometry for the Elucidation of Biological Processes in Ant…
2017
Proteomics based on 2D-Difference In Gel Electrophoresis (2D-DIGE) coupled with mass spectrometry (MS) procedures can be considered a âgold standardâ to determine quantitatively and comparatively protein abundances in cell extracts from different biological sources/conditions according to a gel-based approach. In particular, 2D-DIGE is used for protein specie separation, detection, and relative quantification, whenever tandem MS is used to obtain peptide sequence information that is managed according to bioinformatic procedures to identify the differentially represented protein species. The proteomic results consist of a dynamic portray of over- and down-represented protein species that…
