Validation of a novel automatic deposition of bacteria and yeasts on MALDI target for MALDI-TOF MS-based identification using MALDI Colonyst robot
2017
Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) -based identification of bacteria and fungi significantly changed the diagnostic process in clinical microbiology. We describe here a novel technique for bacterial and yeast deposition on MALDI target using an automated workflow resulting in an increase of the microbes' score of MALDI identification. We also provide a comparison of four different sample preparation methods. In the first step of the study, 100 Gram-negative bacteria, 100 Gram-positive bacteria, 20 anaerobic bacteria and 20 yeasts were spotted on the MALDI target using manual deposition, semi-extraction, wet deposition onto 70% formic …
The Added-Value of Remotely-Sensed Soil Moisture Data for Agricultural Drought Detection in Argentina
2021
In countries where the economy relies mostly on agricultural-livestock activities, such as Argentina, droughts cause significant economic losses. Currently, the most-used drought indices by the Argentinian National Meteorological and Hydrological Services are based on field precipitation data, such as the standardized precipitation index (SPI) and the standardized precipitation evapotranspiration index (SPEI). In this article, we explored the performance of the satellite-based soil moisture agricultural drought index (SMADI) for agricultural drought detection in Argentina during 2010-2015, and compared it with the one from the standardized soil moisture anomalies (SSMA), SPI and SPEI (at on…
Actitudes hacia el alumnado con discapacidad en educación física: validación de la EAADEF-EP a la etapa de educación primaria
2020
La investigación que aborda la inclusión del alumnado con discapacidad en educación física (EF) se presenta como un reto educativo en la actualidad. El objetivo de este estudio fue validar la Escala de Actitud hacia el Alumnado con Discapacidad en Educación Física (EAADEF) de Íñiguez-Santiago et al. (2017) a la etapa de educación primaria (EAADEF-EP). Participaron 465 estudiantes (rango 9-13 años) que cursaban 4º, 5º y 6º curso de la etapa de educación primaria obligatoria (EPO). Se confirmaron unos índices de ajuste adecuados para la adaptación de la EAADEF a EPO, mostrándose la estructura factorial invariante respecto al curso, género, el contacto previo con familiares o amigos con discap…
Institutional Autonomy and the Attractiveness of the European Higher Education Area – Facts or Tokenistic Discourse?
2012
In the discourse of the Bologna Process, the notion of competitiveness as the focal goal of Bologna Process, and university autonomy as one of its founding principles are consistently linked. Autonomy is framed as a precondition of competitiveness, while competitiveness is framed in terms of attractiveness of European higher education and higher education institutions. This paper examines their relationship, discussing whether there is ground for the repeated policy argument of their going hand in hand. Do the more attractive countries have higher autonomy, are the countries with higher autonomy more attractive? Or are these phenomena linked only in the simplified arguments of the policy di…
Sleep Apnea, Sleepiness, and Driving Risk
2019
Obstructive sleep apnea is associated with excessive daytime sleepiness in about 50% of cases, and with increased risk of driving accidents. Treatment with continuous positive airway pressure effectively decreases such risk, but compliance with continuous positive airway pressure treatment is often suboptimal. According to the European Union Directive on driving risk, retention of a driving license in patients with obstructive sleep apnea requires assessment of sleepiness and adherence to continuous positive airway pressure treatment, but there remains uncertainty on the optimal methods to assess sleepiness on a large scale.
Affirmative action in India: redistribuzione di beni e creazione di identità
2009
L’India è probabilmente lo stato in cui l’affirmative action riguarda la più ampia percentuale di popolazione e i più svariati ambiti della vita pubblica; inoltre le prime forme di agevolazione di gruppi svantaggiati previste dal governo risalgono ad oltre 130 anni fa. La reservation policy (il nome con cui in India vengono chiamate le azioni positive) è argomento ricorrente del dibattito pubblico: tema eminente di ogni programma elettorale, influisce fortemente nella costituzione della base dei partiti e nella scelta dei rappresentanti, è contestata o invocata in molte battaglie politiche e in numerosi conflitti sociali che agitano il paese. Ha contribuito fortemente a profilare le identit…
Enterococcal meningitis caused by Enterococcus casseliflavus. First case report
2005
Abstract Background Enterococcal meningitis is an uncommon disease usually caused by Enterococcus faecalis and Enterococcus faecium and is associated with a high mortality rate. Enterococcus casseliflavus has been implicated in a wide variety of infections in humans, but never in meningitis. Case presentation A 77-year-old Italian female presented for evaluation of fever, stupor, diarrhea and vomiting of 3 days duration. There was no history of head injury nor of previous surgical procedures. She had been suffering from rheumatoid arthritis for 30 years, for which she was being treated with steroids and methotrexate. On admission, she was febrile, alert but not oriented to time and place. H…
Importance of Propionibacterium acnes hemolytic activity in human intervertebral discs: A microbiological study
2018
Most patients with chronic lower back pain (CLBP) exhibit degenerative disc disease. Disc specimens obtained during initial therapeutic discectomies are often infected/colonized with Propionibacterium acnes, a Gram-positive commensal of the human skin. Although pain associated with infection is typically ascribed to the body's inflammatory response, the Gram-positive bacterium Staphylococcus aureus was recently observed to directly activate nociceptors by secreting pore-forming α-hemolysins that disrupt neuronal cell membranes. The hemolytic activity of P. acnes in cultured disc specimens obtained during routine therapeutic discectomies was assessed through incubation on sheep-blood agar. T…
Dynamic Antigen Presentation Patterns of Listeria monocytogenes-Derived CD8 T Cell Epitopes In Vivo
2001
Abstract Little information exists regarding the presentation of antigenic peptides in infected tissues. In this study the in vivo presentation of four different CD8 T cell epitopes of Listeria monocytogenes was monitored. Peptide presentation was measured by a new, highly sensitive, ex vivo Ag presentation assay that was based on the testing of freshly isolated cells from infected spleens with peptide-specific CD8 T cell lines in an IFN-γ-specific ELISPOT assay. Remarkably, the peptide presentation pattern of splenocytes and that of macrophages purified from spleens of L. monocytogenes-infected mice were different from those of in vitro infected macrophage-like cell lines. The in vivo Ag p…
