Impact of Cultural Tourism Upon Urban Economies: An Econometric Exercise
In recent years, interest in tourism has spread rapidly throughout many small and medium European cities, which previously have not necessarily considered themselves as tourist destinations. Tourism is increasingly seen as a potential lever towards high economic growth, measured both in terms of income and employment. In the present Working Paper we report the analysis on the economic impact undertaken in the framework of the PICTURE Project, showing the results of a novel econometric exercise to statistically assess the impacts of cultural tourism upon European municipalities. More precisely the analysis aims at estimating the effects of tourism specialisation on local income and prices. The Working Paper is built as follows. Section 1 presents and discusses secondary data about tourism facts and figures, including the economic impact of tourism upon European economies, with a focus on cultural tourism. An extensive review of literature, which identifies the main categories of impacts and the currently available methodologies to assess them, is undertaken. Section 2 focuses on the state of the art. Section 3 describes the database built for the analysis, sources and variables. In order to visually represent the spatial variability of the main parameters, a series of thematic maps at NUTS 3 level(Maps of European tourism), using GIS (Geographical Information System) are also included in the Working Paper. Section 4 shows the results of the econometric analysis of European panel data for the estimation of the effects of tourism specialisation on both local incomes and prices. Section 5 concludes
Biological aspects of NOE2 and PhoNeS experiments
The aim of our study is to validate a BNCT based on a novel neutron source, the Elekta Precise 25MV medical linear accelerator (e-LINAC), to which is applied the PhoNeS photo-neutron converter. Results of experiments on 10 Boron uptake and BPA boron carrier toxicity carried out using two different models: lung with adenocarcinoma and human tumour cells cultured in vitro, are discusse
Highly diastereoselective synthesis of enantiopure naphthylaminoalcohols with analgesic properties
ABSTRACT The diastereoselective synthesis via Grignard reaction of enantiopure
analgesic naphthylaminoalcohols has been performed. The chiral racemic key intermediate
3-dimethylamino-2-methyl-1-(naphthalen-2-yl)propan-1-one and enantiomers were
prepared and transformed into the desired compounds by addition of the organometallic
reagent. The chemical characterization of all diastereoisomers was accomplished by
1H NMR and HPLC analyses and the absolute configuration assigned by CD spectroscopy.
The in vitro and in vivo profile has also been evaluate
Diastereoselective synthesis of chiral nonracemic naphthylaminoalcohols with analgesic activity
Abstract—The diastereoselective synthesis of chiral nonracemic naphthylaminoalcohols has been accomplished. The diastereoisomers, obtained in high enantiomeric excesses, were investigated by 1H NMR and HPLC analyses. The configurational assignment was performed by NOESY 1H NMR spectroscopy. Pharmacological evaluation of the analgesic activity by means of the hot plate test is describe
Chiral arylpyrrolidinols: preparation and biological profile
Abstract—The preparation and biological evaluation of a new class of arylpyrrolidinols is reported. The antinociceptive activity was evaluated in vivo with the hot plate test (HPT) and formalin test (FT), excluding any involvement on motor coordination with the rota-rod test (RRT). The nociceptive behavior in the late phase of FT (representative of chronic pain) suggests an involvement of the antiinflammatory process and it is clearly influenced by the stereochemical features, being the eutomer of phenylpyrrolidinols, the (2R,3S) enantiomer. Despite this, a specific mechanism of action is not yet clarifie
Prolonged non-invasive respiratory support in a COVID-19 patient with severe acute hypoxemic respiratory failure.
A pandemic caused by the Severe Acute Respiratory Syndrome Coronavirus 2 was declared in 2020. Severe cases were characterized by the development of acute hypoxemic respiratory failure (AHRF) requiring advanced respiratory support. However, intensive care units (ICU) were saturated, and many patients had to be treated out of ICU. This case describes a 75-year-old man affected by AHRF due to Coronavirus Disease 2019 (COVID-19), hospitalized in a high-dependency unit, with PaO2/FiO2 <100 for 28 consecutive days. An experienced team with respiratory physiotherapists was in charge of the noninvasive ventilatory support (NIVS). The patient required permanent NIVS with continuous positive airway pressure, non-invasive ventilation, high flow nasal oxygen and body positioning. He was weaned from NIVS after 37 days and started exercise training afterwards. The patient was discharged at home with low-flow oxygen therapy. This case represents an example of a successful treatment of AHRF with the still controversial noninvasive respiratory support in one patient with COVID-19
