Determination of arsenic compounds in beverages by high-performance liquid chromatography-inductively coupled plasma mass spectrometry.
2005
Arsenic compounds including arsenous acid (As(III)), arsenic acid (As(V)), dimethylarsinic acid (DMA) and monomethylarsonic acid (MMA) were separated by high-performance liquid chromatography (HPLC) and detected by inductively coupled plasma mass spectrometry (ICP-MS). A Hamilton PRX-100 anionic-exchange column and a pH 8.5 K(2)HPO(4)/KH(2)PO(4) 5.0x10(-3)molL(-1) mobile phase were used to achieve arsenic speciation. The separation of arsenic species provided peaks of As(III) at 2.75min, DMA at 3.33min, MMA at 5.17min and As(V) at 12.5min. The detection limits, defined as three times the standard deviation of the lowest standard measurements, were found to be 0.2, 0.2, 0.3 and 0.5ngmL(-1) f…
Diagnosis of pregnancy-associated venous thromboembolism - position paper of the Working Group in Women’s Health of the Society of Thrombosis and Hae…
2016
Venous thromboembolism (VTE) is a major cause of maternal morbidity during pregnancy and the postpartum period. However, because there is a lack of adequate study data, management strategies for pregnancy-associated VTE must be deduced from observational stu-dies and extrapolated from recommendations for non-pregnant patients. In this review, the members of the Working Group in Women's Health of the Society of Thrombosis and Haemostasis (GTH) have summarised the evidence that is currently available in the literature to provide a practical approach for treating pregnancy-associated VTE. Because heparins do not cross the placenta, weight-adjusted therapeutic-dose low molecular weight heparin …
Mast cells promote homeostasis by limiting endothelin-1-induced toxicity
2004
Endothelin-1 (ET-1) is a 21-amino-acid peptide, derived from vascular endothelial cells, with potent vasoconstrictor activity. ET-1 has been implicated in diverse physiological or pathological processes, including the vascular changes associated with sepsis. However, the factors that regulate ET-1-associated toxicity during bacterial infections, or in other settings, are not fully understood. Both the pathology associated with certain allergic and autoimmune disorders, and optimal host defence against bacterial and parasitic infections are mediated by mast cells. In vitro, mast cells can produce ET-1 (ref. 11), undergo ET-1-dependent and endothelin-A receptor (ET(A))-dependent activation, a…
Nursing: more used medicines in the emergency rooms of hospitals
2007
El Servicio de Urgencias del C.H.G.U.V. cuenta con una plantilla de 84 Enfermeros/as. Una parte considerable de ellos es personal de nueva incorporación, de ahí que sea prioritaria la elaboración de protocolos de actuación. La administración de medicación intravenosa es sin duda una de las técnicas de mayor aplicación en los pacientes que acuden a Urgencias, que en nuestro Hospital oscila entre 550-600 atenciones diarias. Por ello nos planteamos, mediante la realización de reuniones de grupo, la elaboración del presente trabajo con el objetivo de elaborar un manual informativo sobre la medicación más habitual utilizada en nuestro Servicio de Urgencias; indicaciones, contraindicaciones, dilu…
Fonti storiche e fonti numismatiche a confronto nella Sicilia centro-meridionale della fine del V sec. a.C.
2006
The historical events that involved Sicily at the end of the 5th century BC find a precise description in the X-XIII books of Diodorus Siculus. The numismatic testimonies from the territory of central-southern Sicily, in addition to confirming what has been illustrated by the historian of Agira, integrate and enrich the information, adding data for the same period relating above all to the indigenous centres, neglected by the sources.
The Asynchronous Leontief Model
1992
International audience; The traditional dynamic Leontief model is synchronous: every vertex acts simultaneously. A model with delays of action has been proposed, but it still remains synchronous. In this paper we propose an asynchronous version of the model that allows realistic computations. We fiurnish an algorithm and a program.
Randomized renaming in shared memory systems.
2021
Abstract Renaming is a task in distributed computing where n processes are assigned new names from a name space of size m . The problem is called tight if m = n , and loose if m > n . In recent years renaming came to the fore again and new algorithms were developed. For tight renaming in asynchronous shared memory systems, Alistarh et al. describe a construction based on the AKS network that assigns all names within O ( log n ) steps per process. They also show that, depending on the size of the name space, loose renaming can be done considerably faster. For m = ( 1 + ϵ ) ⋅ n and constant ϵ , they achieve a step complexity of O ( log log n ) . In this paper we consider tight as well as loos…
Impact of wage penalty on mobility return of French PhDs
2015
International audience; Expatriation of higher-education graduates raises much concern in many countries often in conjunction with talk about the brain drain. It supposedly entails a risk of losing the skills required for a competitive economy. The issue is all the more acute for PhD graduates, who are expected to play a major part in the knowledge economy. However, questions arise as to the causes of such mobility and its consequences for young graduates' individual career paths.
Ocena zależności pomiędzy objawami klinicznymi przewlekłej niewydolności żylnej i ultrasonograficznymi cechami refluksu żylnego u chorych z żylakami …
2001
Wstęp: Celem badania było porównanie objawów klinicznych przewlekłej niewydolności żylnej ze stopniem nasilenia refluksu żylnego, stwierdzanym w badaniu ultrasonograficznym u chorych z żylakami kończyn dolnych. Materiał i metody: Badaniu poddano 50 chorych — 100 kończyn dolnych: 23 kończyny bez żylaków (w tych przypadkach żylaki występowały na drugiej kończynie), 13 kończyn z żylakami, które nie powodowały dolegliwości, 49 kończyn z żylakami, którym towarzyszył obrzęk i/lub dolegliwości bólowe, 15 kończyn z żylakami z towarzyszącymi zmianami skórnymi (z wyjątkiem owrzodzenia). Przeprowadzono ultrasonograficzną (USG Duplex-Doppler) ocenę refluksu w żyłach: udowej, podkolanowej, piszczelowej …
