Laparoscopic Sentinel Lymph Node Detection After Hysteroscopic Injection of Technetium-99 in Patients With Endometrial Cancer
2015
Background and Objectives Endometrial cancer (EC) has an increasing incidence worldwide. Despite the unequivocal prognostic importance of nodal status, systematic lymphadenectomy is associated to elevated morbidity. Sentinel lymph node (SLN) biopsy is designed to avoid extensive nodal dissection and provide crucial oncologic information. The goal of this prospective study was to determine the feasibility, safety, and accuracy of laparoscopic SLN biopsy in EC obtained through hysteroscopic injection of technetium-99 (Tc-99). Methods From January 2008 to December 2012, a total of 42 women with EC were included in the study. We injected 20 mBq of Tc-99 hysteroscopically underneath the tumor mi…
Risk of drug-related falls among noninstitutionalized older adults
2017
To determine the number of drugs taken per day, which represents a risk factor for falls among noninstitutionalized older adults with a history of falls in the last year.This was a descriptive study that used random sampling and the following measurement instruments: the WHO questionnaire for the study of falls in older adults, gait scale and geriatric depression scale and gait and balance. Univariate and bivariate analysis, nonparametric chi-squared test, and binary logistic regression were performed using the SPSS statistical program version 21.0.214 individuals participated in the study. Those who took ≥ 4 drugs presented higher risk of falling, p=0.010 OR=4.034. The same was not true fo…
Drug-drug interactions in a cohort of hospitalized elderly patients.
2013
PurposeThe aim of this study is to assess the prevalence of patients exposed to potentially severe drug-drug interactions (DDIs) at hospital admission and discharge and the related risk of in-hospital mortality and adverse clinical events, readmission, and all-cause mortality at 3months. MethodsThis cross-sectional, prospective study was held in 70 Italian internal medicine and geriatric wards. Potentially severe DDIs at hospital admission and discharge; risk of in-hospital mortality and of adverse clinical events, readmission, and all-cause mortality at 3-month follow-up. ResultsAmong 2712 patients aged 65years or older recruited at hospital admission, 1642 (60.5\%) were exposed to at leas…
Immunologische Grundlagen der allergischen Spätreaktion
1965
An transferaktiven Zellen von tb-sensibilisierten Tieren sind mindestens zwei distinkte zellstandige Antikorper nachweisbar. Eine Art dieser Antikorper ist gegen Tuberkulopolysaccharid und die andere gegen Tuberkuloprotein gerichtet. Sie haben beide nach Kontakt mit dem Antigen die Fahigkeit, Komplement zu binden. Eine Cytolyse kommt sowohl durch eine zellstandig ablaufende Immunreaktion zwischen Polysaccharid-Antikorper und Tuberkuloprotein-Antikorper mit dem Antigen zustande, jedoch ist dazu nur im letzteren Falle Komplement erforderlich. Nach Kontakt mit dem Antigen ist also beim Polysacharid-Antikorper eine Komplementbindung moglich, fur eine Cytolyse aber nicht notig. Die beiden zellst…
Antigens of <i>Euparipha pisana</i> (Snail)
1988
The data obtained in this study suggest that eating <i>Euparipha pisana</i> (snail), a common food in Mediterranean countries, could give serious allergic reaction such as asthma. We describe here the identification and partial characterization of allergenic molecules form this new source. An aqueous extract of snail was obtained by homogenization in distilled water, centrifugation, dialysis and defatting with ethyl ether. Skin prick test (SPT) performed with the snail extract on 70 subjects allergic to the more common allergens of the Mediterranean area gave a SPT positivity in 61% of the subjects tested, with a mean value of histamine-equivalent prick (HEP) equal to 0.81 ± 0.2…
Investigation of the aqueous transmetalation of π-allylpalladium with indium salt: the use of the Pd(OAc)2–TPPTS catalyst
2005
pi-Allylpalladium complexes could be generated in water by the palladium(0) water soluble catalyst prepared in situ from palladium acetate and TPPTS. These complexes were transmetalated with indium to react with benzaldehyde. The aqueous solution of Pd(0)(TPPTS)(n) could be reused without deterioration of the catalyst in the first and second recycling. The system proved to be efficient with primary and secondary allylic substrates. The stereochemical outcome of the allylation through umpolung of allylpalladium, was also studied using models with a restraint conformation.
Immuno-SLM—a combined sample handling and analytical technique
2004
Immuno-supported liquid membrane (immuno-SLM) extraction is a new technique that makes use of antibody (Ab)-antigen interactions as the "extraction force" to drive the mass transfer in a selective way. In immuno-SLM, anti-analyte (Ag) Abs are introduced into the acceptor phase of the SLM unit to trap the Ag that passes from the flowing donor through the SLM into the stagnant acceptor. The amount of immuno-extracted analyte (AbAg) is quantified by connecting the immuno-SLM unit on-line with a non-competitive heterogeneous fluorescence flow immunoassay (FFIA) that makes use of a fluorescein-labeled analyte tracer that titrates the residual excess of Ab present in the acceptor. A restricted ac…
Preparation and photoactivity of nanostructured anatase, rutile and brookite TiO2 thin films
2006
Photoactive films consisting of pure anatase, brookite or rutile TiO2 were prepared by dip coating from water dispersions obtained by using TiCl4 as the precursor under similar mild experimental conditions
First isomeric yield ratio measurements by direct ion counting and implications for the angular momentum of the primary fission fragments
2018
We report the first experimental determination of independent isomeric yield ratios using direct ion counting with a Penning trap, which offered such a high resolution in mass that isomeric states could be separated. The measurements were performed at the Ion Guide Isotope Separator On-Line (IGISOL) facility at the University of Jyvaskyla. The isomer production ratios of Ge-81, Y-96,Y-97 Sn-128(,1)30, and Sb-129 in the 25-MeV proton-induced fission of U-na(t) and Th-232 were studied. Three isomeric pairs (Ge-81, Y-96, and Sb-129) were measured for the first time for the U-na(t)(p, f) reaction, while all the reported yield ratios for the Th-232(p, f) reaction were determined for the first ti…
Ring splitting of azetidin-2-ones via radical anions
2012
The radical anions of azetidin-2-ones, generated by UV-irradiation in the presence of triethylamine, undergo ring-splitting via N-C4 or C3-C4 bond breaking, leading to open-chain amides. This reactivity diverges from that found for the neutral excited states, which is characterised by alpha-cleavage. The preference for beta-cleavage is supported by DFT theoretical calculations on the energy barriers associated with the involved transition states. Thus, injection of one electron into the azetidin-2-one moiety constitutes a complementary activation strategy which may be exploited to produce new chemistry.
