Food proteins and peptides

The qualitative and quantitative determination of proteins and peptides in raw or processed food is experiencing a growing interest and importance from both scientific and economic point of view. Proteomics and peptidomics are relatively new entries in the field of food security, safety and authenticity, and themselves can contribute to the emergence of new branches of the science of food, such as foodomics and the just born nutriomics, digestomics, and gut metagenomics/metaproteomics. Mass spectrometry, in combination with a wide variety of separation methods and bioinformatic tools, is the principal methodology for proteomics. Both the so-called "in-gel" and "gel-free shotgun" bottom-up approaches are widely used.Among the arguments described in this chapter there are: stress effects on gene expression, postharvest (plant) and postmortem (livestock) protein modification, food safety, quality and authentication, food processing and quality control, frauds discovery, food peptidomics and digestomics. © 2015 Elsevier B.V

A rapid magnetic solid phase extraction method followed by liquid chromatography-tandem mass spectrometry analysis for the determination of mycotoxins in cereals

Mycotoxins can contaminate various food commodities, including cereals. Moreover, mycotoxins of different classes can co-contaminate food, increasing human health risk. Several analytical methods have been published in the literature dealing with mycotoxins determination in cereals. Nevertheless, in the present work, the aim was to propose an easy and effective system for the extraction of six of the main mycotoxins from corn meal and durum wheat flour, i.e., the main four aflatoxins, ochratoxin A, and the mycoestrogen zearalenone. The developed method exploited magnetic solid phase extraction (SPE), a technique that is attracting an increasing interest as an alternative to classical SPE. Therefore, the use of magnetic graphitized carbon black as a suitable extracting material was tested. The same magnetic material proved to be effective in the extraction of mycoestrogens from milk, but has never been applied to complex matrices as cereals. Ultra high-performance liquid chromatography tandem mass spectrometry was used for detection. Recoveries were > 60% in both cereals, even if the matrix effects were not negligible. The limits of quantification of the method results were comparable to those obtained by other two magnetic SPE-based methods applied to cereals, which were limited to one or two mycotoxins, whereas in this work the investigated mycotoxins belonged to three different chemical classes

Thermal log analysis for recognition of ground surface temperature change and water movements

International audienceA joint analysis of surface air temperature series recorded at meteorological stations and temperature-depth profiles logged in near-by boreholes was performed to estimate conditions existing prior to the beginning of the instrumental record in central-northern Italy. The adopted method considers conductive and advective heat transport in a horizontally layered medium and provides simultaneous estimates of the pre-observational temperatures and the Darcy velocities. The reconstruction of the ground surface temperature history using an inversion method was performed for boreholes where hydrological disturbances to measured temperature logs were proved to be negligible. Both methods revealed generally coherent climatic changes in the whole investigated area. Climatic conditions were generally warm and comparable with the reference period 1960?1990. The absence of the Little Ice Age in the middle ages seems to be a generic feature of the climate in central-northern Italy. Climate change of the 19th century was generally insignificant with well balanced periods of cold and warmth. The investigated area became significantly colder only at the end of the 19th century. Cooling culminated around 1950 when it was replaced by rapid warming. Recent warming was not inferred only for one of the investigated holes. This discrepancy can be attributed to local environmental conditions

METHODOLOGICAL FRAMEWORK TO IMPROVE PPP PROJECTS

The Public–Private Partnership (PPP) plays a significant role in the construction industry. It is of special importance because of its weight in the global economy and the lack of funding for major projects. The PPP concept, as a procurement strategy, is successful only if the major stakeholders, namely the public sector, private consortium, and end–users are all satisfied with project outcomes. There have been reported cases of problems associated with the initial stages of the PPP process in terms of bidding costs and anticipated costs of construction and operation. The banks’ attention is currently centered on the promotors’ financial stability rather than on project quality. The key issue is to improve the efficiency for the whole building lifecycle. In this context, BIMM philosophy (not just Building Information Modeling but also Information Management) may be a powerful tool. In other words, is there room to put this concept in practice without jeopardizing service quality, innovation and efficiency? The answer to this question is explored in this paper. The use of Technical Sheets for PPP procurement like policy models may enhance systematic and integrated management of the whole building process. This technical framework allows one to collect project data, grouped into three areas: design, construction, and operation. In so doing, a Public Agency may assess project quality

Knee stability, athletic performance and sport-specific tasks in non-professional soccer players after ACL reconstruction: comparing trans-tibial and antero-medial portal techniques.

Background: a wrong position of bone tunnels, in particular on the femur, is one of the most frequent causes of a failed anterior cruciate ligament (ACL) reconstruct ion. Several studies demonstrated that drilling the femoral tunnel through the antero-medial portal (AMP) allows a more anatomical placement on the lateral femoral condyle and higher knee stability, compared to trans-tibial (TT) technique. The aim of this study was to retrospectively evaluate two groups of soccer players operated on for ACL reconstruction according to either one of these two techniques. Methods: two groups of non-professional soccer players operated on for a single bundle ACL reconstruction with hamstrings autograft using either a TT (20 patients) or an AMP (23 patients) technique were retrospectively evaluated with KT- 1000 arthrometer, manual pivot shift test, isokinetic test, the incremental treadmill-running test, athletic and sport specific tasks, and knee scores (IKDC, Lysholm and KOOS). Results: the AMP group showed better results at pivot shift test and KOOS, but lower flexion angles at single leg squat test. There were no differences in all the other considered outcomes. Conclusions: the better rotational stability of the knee achieved in AMP group did not lead to significantly better clinical and functional results in our patients. Level of evidence III. Treatment study: Case-control study

Development status of the LAUE project

We present the status of LAUE, a project supported by the Italian Space Agency (ASI), and devoted to develop Laue lenses with long focal length (up to 100 meters), for hard X--/soft gamma--ray astronomy (80-600 keV). Thanks to their focusing capability, the design goal is to improve the sensitivity of the current instrumention in the above energy band by 2 orders of magnitude, down to a few times $10^{-8}$ photons/(cm$^2$ s keV).Comment: 9 pages, 9 figures, presented at the Space Telescopes and Instrumentation Symposium in Amsterdam, 2012: Ultraviolet to Gamma Ray Conference.

Pharmacoproteomic characterisation of human colon and rectal cancer

Most molecular cancer therapies act on protein targets but data on the proteome status of patients and cellular models for proteome-guided pre-clinical drug sensitivity studies are only beginning to emerge. Here, we profiled the proteomes of 65 colorectal cancer (CRC) cell lines to a depth of > 10,000 proteins using mass spectrometry. Integration with proteomes of 90 CRC patients and matched transcriptomics data defined integrated CRC subtypes, highlighting cell lines representative of each tumour subtype. Modelling the responses of 52 CRC cell lines to 577 drugs as a function of proteome profiles enabled predicting drug sensitivity for cell lines and patients. Among many novel associations, MERTK was identified as a predictive marker for resistance towards MEK1/2 inhibitors and immunohistochemistry of 1,074 CRC tumours confirmed MERTK as a prognostic survival marker. We provide the proteomic and pharmacological data as a resource to the community to, for example, facilitate the design of innovative prospective clinical trials. © 2017 The Authors.

ANDIL experience for building process optimization through an efficient data management / L’esperienza di ANDIL per l’ottimizzazione del processo edilizio attraverso una gestione efficiente delle informazioni

A building process optimization needs a systemic approach in order to correctly manage its complexity. Despite many important contributions have been provided in the last few years, both from a procedural point of view and from a normative one, building process management is often fragmented. This may cause repercussions on building quality and inefficiency in cost and time management. That is why, the research project INNOVance has developed an unambiguous classification system for every object and informative attribute for construction, creating a unique database to smartly store and share information. This through a proper definition of the content of data sheets which can be collected and easily shared together with their complementary attributes by different stakeholders. Unambiguous language and standardized information, in and of themselves, increase building process efficiency. If we then consider that data exchange is possible through the exploitation of a user friendly web portal and some interoperable web services, efficiency and economic savings in the entire construction chain could be extremely relevant. The present paper describes the results achieved during the last year of the research project, in terms of information standardization and data collection
