Antioxidant Properties of a Supercritical Fluid Extract of the Halophyte Mesembryanthemum nodiflorum L. from Sicilian Coasts: Nutraceutical and Cosme…

2020

The aim of this paper was to obtain different extracts from the aerial parts of Mesembryanthemum nodiflorum, comparing traditional extraction (using solvents with increasing polarity such as hexane, ethanol 80%, acetone 70% and water) with an eco-friendly technique (supercritical fluid extraction (SFE))

Modelo Barcelona y política cultural: usos y abusos de la cultura por parte de un modelo emprendedor de desarrollo local

2015

El Modelo Barcelona de desarrollo local ha sido intensamente debatido· Desde su inicio en los años ochenta hasta la actualidad, diversos autores han analizado sus características como modelo, destacado sus éxitos y también sus puntos débiles. No obstante, menos atención ha recibido la relación que existe entre el modelo de desarrollo local y el modelo de política cultural, a pesar de que Barcelona también es internacionalmente conocida por su dinamismo cultural. De manera habitual, este modelo de política cultural ha sido interpretado como un instrumento en la agenda de desarrollo local. El presente artículo mostrará, a partir de análisis de diversos casos ejemplares, que la política cultur…

Microwave-Assisted Synthesis of New Selenazole Derivatives with Antiproliferative Activity

2013

New aryl-hydrazinyl-1,3-selenazole and aroyl-hydrazonyl-1,3-selenazoles were synthesized via Hantzsch type condensation reactions of selenosemicarbazides with α-halogenocarbonyl derivatives, under classical versus microwave heating conditions. Excellent yields and shorter reaction times were obtained under irradiation conditions. The structures of the synthesized compounds were assigned based on spectroscopic data (FT-IR, 1 H-NMR), MS and elemental analysis. Selenazole derivatives were screened for their anti-proliferative effects against two leukemia cell lines (CCRF-CEM and HL60) and three carcinoma cell lines (MDA-MB231, HCT116 and U87MG).

A Derivation of the Vlasov-Stokes System for Aerosol Flows from the Kinetic Theory of Binary Gas Mixtures

2016

In this short paper, we formally derive the thin spray equation for a steady Stokes gas, i.e. the equation consists in a coupling between a kinetic (Vlasov type) equation for the dispersed phase and a (steady) Stokes equation for the gas. Our starting point is a system of Boltzmann equations for a binary gas mixture. The derivation follows the procedure already outlined in [Bernard-Desvillettes-Golse-Ricci, arXiv:1608.00422 [math.AP]] where the evolution of the gas is governed by the Navier-Stokes equation.

Thermal transformation of micro-crystalline cellulose in phosphoric acid

2011

Use of crude oil derivatives such as diesel and gasoline is becoming unsuitable due to their detriment to environment and to the increasing worldwide energy demand which is driving crude oil reservoirs towards exhaustion. Replacement of diesel and gasoline with biofuels (i.e. biodiesel and bioethanol, respectively) is very desirable. In fact, biofuels are not only environmentally sustainable, but also potentially inexhaustible due to the large amounts of waste biomasses from which they can be retrieved. In the present study, a model compound (micro-crystalline cellulose) was dissolved in phosphoric acid and converted at 80 °C to glucose, thereby providing the possible substrate for fermenta…

How school nurses experience and understand everyday pain among adolescents

2017

Abstract Background Pain problems are a rapidly growing health problem found among both children and adolescent, and about 15–30% have reported chronic pain problems. School nurses in Norway meet adolescents with various ailments, including pain. Yet research on how school nurses perceive the pain experienced by adolescents is limited. The aim of the present study was to explore how school nurses explain and experience the everyday pain of adolescents. Method A qualitative study with an explorative design comprising five focus group interviews. Each group consisted of three to five school nurses. Seventeen female school nurses in five junior high schools in Norway, age range 29–65 years par…

Prognostic factors and risk groups in T1G3 patients initially treated with BCG: Results of a multicenter retrospective series in 1743 patients

2013

Introduction and Objectives: The impact of prognostic factors in T1G3 patients (pts) is critical for proper treatment decision making, however most available data are from small series of pts. The aim of the current study is to assess prognostic factors in a large group of pts who received BCG as initial treatment of T1G3 tumours and identify a subgroup of high risk pts who should be considered for early cystectomy. Patients and Methods: Individual pt data were collected for 1743 ptsfrom 20 centers who received induction or maintenance BCG between 1990 and 2008. Using Cox regression analysis, the prognostic importance of the following variables were assessed for time to recurrence, progress…
