Do ventilatory parameters influence outcome in patients with severe acute respiratory infection? Secondary analysis of an international, multicentre1…
2021
Purpose: To investigate the possible association between ventilatory settings on the first day of invasive mechanical ventilation (IMV) and mortality in patients admitted to the intensive care unit (ICU) with severe acute respiratory infection (SARI). Materials and methods: In this pre-planned sub-study of a prospective, multicentre observational study, 441 patients with SARI who received controlled IMV during the ICU stay were included in the analysis. Results: ICU and hospital mortality rates were 23.1 and 28.1%, respectively. In multivariable analysis, tidal volume and respiratory rate on the first day of IMV were not associated with an increased risk of death; however, higher driving pr…
Inducible ASABF-Type Antimicrobial Peptide from the Sponge Suberites domuncula: Microbicidal and Hemolytic Activity in Vitro and Toxic Effect on Moll…
2011
Since sponges, as typical filter-feeders, are exposed to a high load of attacking prokaryotic and eukaryotic organisms, they are armed with a wide arsenal of antimicrobial/cytostatic low-molecular-weight, non-proteinaceous bioactive compounds. Here we present the first sponge agent belonging to the group of ASABF-type antimicrobial peptides. The ASABF gene was identified and cloned from the demospongeSuberites domuncula. The mature peptide, with a length of 64 aa residues has a predicted pI of 9.24, and comprises the characteristic CSαβ structural motif. Consequently, the S. domuncula ASABF shares high similarity with the nematode ASABFs ; it is distantly related to the defensins. The recom…
Lielvaru (ASV un Ķīnas) sāncensība 21. gadsimtā
2022
Maģistra darba “Lielvaru (ASV un Ķīnas) sāncensība 21. gadsimtā” mērķis ir vairāku lielvaru augšupejas un lejupslīdes teoriju aplūkošana un analīze, saistot tās ar empīriskajiem novērojumiem par šādu sāncensību. Maģistra darbā apskatītās teorijas tiks pretnostatītas ASV un Ķīnas kā lielvaru sāncensībai mūsdienās, tādējādi veicinot izpratni par iespējamo šādas sāncensības izcelsmi un norisi, izrietot no vēsturiskiem gadījumiem, kas saistīti ar lielvaru sāncensību. Darba teorētiskā bāze ietver izklāstu par lielvaru raksturojumu un vairāku citu jēdzienu apskatīšanu, kā arī apskata četras lielvaru sāncensības teorijas. Maģistra darba empīrisko daļu veido lielvaru sāncensības vēsturiskā ietvara …
AUGMENTED REALITY
2011
Already used in very specific areas such as in military and medical or academic research, in 2009 thanks to improved technology, augmented reality is to reach wider audiences and as information campaigns, advertising-augmented published in newspapers or on the network, and through a growing number of applications for mobile phones, particularly iPhone. "The Augmented Reality on the desktop computer is based on the use of markers, or ARtags, and stylized drawings, which are shown to the webcam, are recognized by the PC, and which are overlaid in real-time multimedia content: video, audio , 3D objects, etc.. Normally, applications of augmented reality are based on Adobe Flash technology and t…
Audiovisual time-to-collision estimation for accelerating vehicles: The acoustic signature of electric vehicles impairs pedestrians' judgments
2022
To avoid collisions, pedestrians intending to cross a road need to accurately estimate the time-to-collision (TTC) of an approaching vehicle. For TTC estimation, auditory information can be considered particularly relevant when the approaching vehicle accelerates. The sound of vehicles with internal combustion engine (ICEVs) provides characteristic auditory information about the acceleration state (increasing speed and engine load). However, for electric vehicles (EVs), the acoustic signature during acceleration is less salient. Although the auditory detection of EVs has been studied extensively, there is no research on potential effects of the altered acoustic signature of EVs on TTC estim…
Bacterial community response to changes in a tri-trophic cascade during a whole-lake fish manipulation
2015
Microbial communities play a key role in biogeochemical processes by degrading organic material and recycling nutrients, but can also be important food sources for upper trophic levels. Trophic cascades might modify microbial communities either directly via grazing or indirectly by inducing changes in other biotic or in abiotic factors (e.g., nutrients). We studied the effects of a tri-trophic cascade on microbial communities during a whole-lake manipulation in which European perch (Perca fluviatilis) were added to a naturally fishless lake divided experimentally into two basins. We measured environmental parameters (oxygen, temperature, and nutrients) and zooplankton biomass and studied th…
Endovenous ablation of refluxing saphenous and perforating veins.
2017
Abstract. Since the end of the nineties endovenous thermal ablation and more recently non-thermal, non-tumescent techniques have been developed and improved. Until now, because of their favourable side effect profile in conjunction to sustained efficacy, in many countries they already replaced high ligation and stripping in the treatment of refluxing saphenous veins as well as for treatment of perforators and selected tributaries. Now, studies and comparative trials are available with long-term follow-ups for most of the techniques, providing valid data on occlusion and reflux rates, side effect profiles, and health related quality of life.
Liturgia y monarquía. La legitimación del poder monárquico en la Valencia barroca
1993
El estudio de las ceremonias religiosas celebradas en la Valencia del siglo XVII con motivo de acontecimientos relacionados con la Monarquía es el objetivo de este trabajo. Nacimientos, bodas o fallecimientos de reyes, reinas o príncipes son motivo de celebración dada su importancia política. Así, la evolución monárquica interna y la situación internacional del Estado bien merecen una oración. Ésta tiene su razón de ser en el contexto de un pensamiento político basado en la idea del origen divino del poder real, en la estrecha relación entre Monarquía y Religión, y en el marco mental de la espiritualidad barroca. Es éste, por tanto, un recorrido por las formas de expresión de la sacralizaci…
Cloud-based eHealth video encoding system for real time thermographic streaming: Performance evaluation
2017
Recent studies about the use of cloud platforms indicate that more than three-fourths of healthcare institutions apply these technologies in their daily lives. However, in most cases the cloud is based on “Infrastructure as a Service”, instead of developing new applications using the benefits that can bring us this type of technology. For these reasons, this paper shows a private cloud-based system to provide a new application based on thermographic video streaming. In this case, the cloud architecture is divided into three zones. The first zone is where the patient is under medical supervision through body temperature analysis using a global thermal camera. The second zone is the cloud its…
Rapid, cost-effective, sensitive and quantitative detection of Acinetobacter baumannii from pneumonia patients
2011
Background and Objectives: Pneumonia with Acinetobacter baumannii has a major therapeutic problem in health care settings. Decision to initiate correct antibiotic therapy requires rapid identification and quantification of organism. The aim of this study was to develop a rapid and sensitive method for direct detection of A. baumannii from respiratory specimens. Materials and Methods: A Taqman real time PCR based on the sequence of blaoxa-51 was designed and used for direct detection of A. baumannii from 361 respiratory specimens of patients with pneumonia. All specimens were checked by conventional bacteriology in parallel. Results: The new real time PCR could detect less than 200 cfu per m…
