Cardiovascular Events During and After Bronchiectasis Exacerbations and Long-term Mortality.
2022
ABSTRACT Background Population-based and retrospective studies have shown that risk for cardiovascular events such as arrythmias, ischemic episodes or heart failure, increase during and after bronchiectasis exacerbations. Research Question What are the risk factors for cardiovascular events (CVE) during and after bronchiectasis exacerbations and its impact on mortality? Study Design and Methods This was a post-hoc retrospective analysis of a prospective observational study of 250 patients with bronchiectasis at two tertiary care hospitals. Only the first exacerbation was considered for each patient, collecting demographic, comorbidity, and severity data. The main outcomes were the appearanc…

Banach partial *-algebras: an overview
2019
A Banach partial $*$-algebra is a locally convex partial $*$-algebra whose total space is a Banach space. A Banach partial $*$-algebra is said to be of type (B) if it possesses a generating family of multiplier spaces that are also Banach spaces. We describe the basic properties of these objects and display a number of examples, namely, $L^p$-like function spaces and spaces of operators on Hilbert scales or lattices. Finally we analyze the important cases of Banach quasi $*$-algebras and $CQ^*$-algebras.
Comparison of iron acquisition from Fe–pyoverdine by strategy I and strategy II plants
2011
; Iron is an essential micronutrient for plants and associated microorganisms. However, the bioavailability of iron in cultivated soils islow. Plants and microorganisms have thus evolved active strategies of iron uptake. Two different iron uptake strategies have been described in dicotyledonous and monocotyledonous graminaceous species. In bacteria,this strat-egy relies on the synthesis of siderophores. Pyoverdines, a major class of siderophores produced byfluorescent pseudomo-nads, were previously shown topromote ironnutrition of the dicotyledonous species ArabidopsisthalianaL.(Heynh.), whereas contradictory reports were made on the contribution of those siderophores to the nutrition of g…
Neutrino transport in coherent quasiparticle approximation
2012
We introduce the coherent quasiparticle approximation (cQPA), a model in thermal quantum field theory which describes various effects of temporally varying thermal medium on particle propagation. We present the cQPA Feynman rules and develop related calculational tools. Using these methods we calculate neutrino self energies in the Standard Model and derive an equation of motion for neutrino propagation in a very general framework. Some immediate implications of this equation are discussed. (More detailed abstract in the PDF file.)
Immunopathology and Immunosenescence, the Immunological Key Words of Severe COVID-19. Is There a Role for Stem Cell Transplantation?
2021
The outcomes of Coronavirus disease-2019 (COVID-19) vary depending on the age, health status and sex of an individual, ranging from asymptomatic to lethal. From an immunologic viewpoint, the final severe lung damage observed in COVID-19 should be caused by cytokine storm, driven mainly by interleukin-6 and other pro-inflammatory cytokines. However, which immunopathogenic status precedes this “cytokine storm” and why the male older population is more severely affected, are currently unanswered questions. The aging of the immune system, i.e., immunosenescence, closely associated with a low-grade inflammatory status called “inflammageing,” should play a key role. The remodeling of both innate …
HIV plays (and wins) a game of T cell Brinkmanship.
2013
HIV, unlike other viruses, may benefit from immune recognition by preserving the sequence of its T cell epitopes, thereby enhancing transmission between cells.
Influences of heat seal lacquer thickness on the quality of blister packages.
2011
A sealability of aluminium lidding foils against formable polymer materials of blister packages is usually achieved by a coating of aluminium with certain grammages of heat seal lacquers. To investigate influences of their thickness on quality of blister packages, lidding foils with different grammages of two lacquer types were manufactured. Sealing experiments (variation of temperature, pressure and sealing time) were performed. Sealed seam strengths were determined with mechanical tensile tests, tightness of cold form blisters were analysed by means of helium leakage tests. Time-dependent moisture uptake of stored blisters was monitored with micro-gas chromatography. By means of a simple …
Caratterizzazione qualitativa e tecnologica delle acque per uso irriguo nel sottobacino Iudeo-Bucari (TP)
2014
In questo lavoro vieneampliatal’indaginesulla qualità di uncampione rappresentativo di acque prelevate nel sottobacino Iudeo-Bucari (TP), già pubblicata. Infatti, precedentemente è stato definito il grado d'idoneità all'uso irriguo delle acque campionate investigandone le caratteristiche chimico-fisiche (Raimondi et al., 2013 b). In questo lavoro si è effettuata la caratterizzazione tecnologica delle acque, in modo da valutare l'interazione acque - impianti irrigui e acque impianti idrici delle strutture edilizie aziendali attraverso la determinazione del potere aggressivo o incrostante delle stesse acqueapplicando l'indice di saturazione di Langeliere di Ryznar. In questo modo viene comple…
