Bloodstream infections in intensive care unit patients: Distribution and antibiotic resistance of bacteria
2015
Vincenzo Russotto,1 Andrea Cortegiani,1 Giorgio Graziano,2 Laura Saporito,2 Santi Maurizio Raineri,1 Caterina Mammina,2 Antonino Giarratano1 1Department of Biopathology and Medical Biotechnologies (DIBIMED), Section of Anaesthesia, Analgesia, Intensive Care and Emergency, Paolo Giaccone University Hospital, University of Palermo, Palermo, Italy; 2Department of Sciences for Health Promotion and Mother-Child Care, University of Palermo, Palermo, Italy Abstract: Bloodstream infections (BSIs) are among the leading infections in critically ill patients. The case-fatality rate associated with BSIs in patients admitted to intensive care units (ICUs) reaches 35%–50%. The emergence and diffusi…
Enantioselective determination of plasma protein binding of common amphetamine-type stimulants.
2021
Amphetamine-type stimulants (ATS) like amphetamine ('speed'), methamphetamine ('crystal meth') and 3,4-methylenedioxy-N-methylamphetamine (MDMA, 'ecstasy') represent some of the most frequently abused drugs worldwide. Another less frequently abused ATS is 4-fluoroamphetamine (4-FA). The enantiomers of these four compounds exhibit different pharmacokinetic and pharmacodynamic properties. According to the free drug theory, the pharmacological properties of a substance are dependent on its plasma protein binding (PPB). However, data on PPB of stimulant enantiomers in humans are rare or non-existent. Human plasma samples were spiked with racemic mixtures of the stimulants and subjected to ultra…
Subjektīvais un objektīvais izvērtējums sievietēm urīna nesaturēšanas gadījumā
2022
Maģistra darba ietvaros tiek pētīta urīna nesaturēšana kā aktuāla problēma sievietēm, tās diagnostikas iespējas un likumsakarības starp dzemdību skaitu, vecuma palielināšanos, ķermeņa masas indeksu un menopauzes iestāšanos. Darbs ir padziļināts pētījums, kas aizsācies jau autores bakalaura darba ietvaros. Sistemātiskie pārskati par šo problēmu norāda uz progozēm, ka slogs uz sabiedrību, pieaugot šai veselības problēmai, ievērojami palielināsies iedzīvotājiem novecojot. Pētījumu rezultāti liecina, ka urīna nesaturēšanas problēma ir pozitīvi saistīta ar dzīvesveidu, ķermeņa masas indeksu, vecumu un menopauzes iestāšanos. Arī dzemdību un ginekoloģiskiem faktoriem, kā arī menopauzes iestāšanās …
Data from: Key roles for freshwater Actinobacteria revealed by deep metagenomic sequencing
2014
Freshwaters ecosystems are critical but fragile environments directly affecting society and its welfare. However, our understanding of genuinely freshwater microbial communities, constrained by our capacity to manipulate its prokaryotic participants in axenic cultures, remains very rudimentary. Even the most abundant components, freshwater Actinobacteria, remain largely unknown. Here, applying deep metagenomic sequencing to the microbial community of a freshwater reservoir, we were able to circumvent this traditional bottleneck and reconstruct de novo seven distinct streamlined actinobacterial genomes. These genomes represent three new groups of photoheterotrophic, planktonic Actinobacteria…

An EEMD Aided Comparison of Time Histories and Its Application in Vehicle Safety
2017
In the context of signal processing, the comparison of time histories is required for different purposes, especially for the model validation of vehicle safety. Most of the existing metrics focus on the mathematical value only. Therefore, they suffer the measuring errors, disturbance, and uncertainties and can hardly achieve a stable result with a clear physical interpretation. This paper proposes a novel scheme of time histories comparison to be used in vehicle safety analysis. More specifically, each signal for comparison is decomposed into a trend signal and several intrinsic mode functions (IMFs) by ensemble empirical mode decomposition. The trend signals reflect the general variation a…
Learning Outcomes in HMD-VR: a Literature Review
2022
While the educational technology has developed to the point that Extended Reality (XR), including immersive Virtual Reality (VR) can be used in education, the learning outcomes of these technologies in the large scale is still quite unknown. This literature review aims to take a comprehensive look to the field of immersive VR in to find out where the learning outcomes of HMD-VR stands out, and how they compare to other technologies and methods. The main result of this paper is that while HMD-based Virtual Reality Learning Environments (VRLEs) may not be superior compared to other technologies such as desktop-based VR environments regarding direct learning outcomes, a clear indication toward…
