Docetaxel plus prednisone in patients with metastatic hormone-refractory prostate cancer: An Italian clinical experience
2011
Aims and Background: We investigated the efficacy of docetaxel plus prednisone in Italian patients with metastatic hormone- refractory prostate cancer (mHRPC). Methods: Twenty four patients with mHRPC received docetaxel 75 mg/m2 every 3 weeks plus prednisone 5 mg twice daily for up to six cycles. The primary endpoint was efficacy measured by a reduction in serum prostate specific antigen (PSA) levels and measurable disease. Evaluation of toxicity, quality of life and reduction of pain were secondary endpoints. Results: PSA response was seen in 18 patients (75%). We observed a partial response in 2 patients (8.3%), stable disease in 10 patients (41.7%), and disease progression in 12 patients…
Moving European research on work and ageing forward: Overview and agenda:
2010
This paper summarizes the state of affairs of European research on ageing and work. After a close inspection of the age construct, an overview is presented of research in four areas: the relationship between age and HR-policies, early retirement, age and performance/employability, age and health/well-being. The overview results in a research agenda on work and ageing and in recommendations for practice. © 2009 Psychology Press. ispartof: European Journal of Work and Organizational Psychology vol:19 issue:1 pages:76-101 status: published
Beyond Biodegradability of Poly(lactic acid): Physical and Chemical Stability in Humid Environments
2017
International audience; Poly(lactic acid) (PLA) is the most traded biodegradable and biobased material. It is largely used as ecofriendly substitute of conventional plastics. Nevertheless, one of the main limiting factors is its water sensitivity. PLA reacts with water and is hydrolyzed during time, which determines its performance. Limited information related to the hydrolysis mechanism driven by water in vapor state is available in scientific literature. Literature is mainly focused on the effects of water in liquid state. This lack of information is of significant importance, since PLA interacts with water in both phases. This work was aimed to give a full depiction of the chemical and p…
Dexamethasone and oxygen therapy in care home residents with diabetes: a management guide and algorithm for treatment: a rapid response action statem…
2021
AbstractThis statement addresses the need to provide clinically relevant and practical guidance for long-term care staff working in care homes and other stakeholders engaged in the care of residents who require consideration for dexamethasone and oxygen therapy. It had been provided following a series of consensus discussions between the EDWPOP and the EuGMS in January and February 2021. Its main aim is to minimise morbidity and mortality from serious acute illnesses including COVID-19 requiring these treatments within the long-term care sector.
Examining the effects of birth order on personality.
2015
This study examined the long-standing question of whether a person’s position among siblings has a lasting impact on that person’s life course. Empirical research on the relation between birth order and intelligence has convincingly documented that performances on psychometric intelligence tests decline slightly from firstborns to laterborns. By contrast, the search for birth-order effects on personality has not yet resulted in conclusive findings. We used data from three large national panels from the United States (N = 5,240), Great Britain (N = 4,489), and Germany (N = 10,457) to resolve this open research question. This data base allowed us to identify even very small effects of birth o…
Current state and future of biogas and digestate production
2013
Over the past few years, the worldwide cost of energy has increased significantly, due to a growing global demand for energy and the decreasing availability of fossil fuel sources. Many countries are adopting environmental policies promoting the production and consumption of alternative, sustainable and renewable energy sources. Among these sources is green energy production through the anaerobic digestion of agricultural feedstock, like animal manure and food industry by-products, mainly aimed at producing biogas. Nevertheless, only a very small part of the biogas potential is currently used, while many European countries are facing huge problems caused by the overproduction of organic was…
Soil organic carbon stocks under recommended management practices in different soils of semiarid vineyards
2019
The Intergovernmental Panel on Climate Change (IPCC) approach is widely used to estimate the C account through the use of standardized coefficients that are not site specific. For these reasons, the aim of the work was to define specific IPCC coefficient taking into account differences in pedological characteristics that affect soil C steady state. In a vineyard area of Sicily, the effectiveness of 5 years of recommended management practice (RMP) adoption on soil organic carbon (SOC) stock increases was evaluated by considering 100 paired sites distributed over four functional soil groups. Each site consisted of two neighbouring plots. The soil of one plot was managed with cover crops accor…
Temperature dependent properties of environmentally important synthetic musks.
2002
Environmental fate determining physical properties including their temperature dependence for five nitro musks and for seven polycyclic musks were estimated. The properties evaluated were vapor pressure in a solid and liquid state (PS and PL), solubility in water (S), Henry's law coefficient (H = PL/S) and log octanol-water partition coefficient (log KOW). Gas chromatography for starting values of vapor pressure estimation and HPLC experiments at 5-20 degrees C for comparison of the theoretical versus experimental solubilities in water were performed. The values of temperature (T) dependence coefficients (Ai and Bi) in equations: log (Property)i = Ai - Bi/T were determined. Values of proper…
Aminoacid zwitterions in solution : Geometric, energetic, and vibrational analysis using density functional theory-continuum model calculations
1998
Glycine and alanine aminoacids chemistry in solution is explored using a hybrid three parameters density functional (B3PW91) together with a continuum model. Geometries, energies, and vibrational spectra of glycine and alanine zwitterions are studied at the B3PW91/6-31+G∗∗ level and the results compared with those obtained at the HF and MP2/6-31+G∗∗ levels. Solvents effects are incorporated by means of an ellipsoidal cavity model with a multipolar expansion (up to sixth order) of the solute’s electrostatic potential. Our results confirm the validity of the B3PW91 functional for studying aminoacid chemistry in solution. Taking into account the more favorable scaling behavior of density funct…
Ajuste psicológico en cuidadores familiares de adolescentes: un análisis longitudinal durante el confinamiento por la COVID-19 en España
2021
Debido al confinamiento por la COVID-19, las familias españolas tuvieron que adaptarse a nuevas situaciones y rutinas. El objetivo de esta investigación ha sido conocer qué variables explicaban el ajuste psicológico de cuidadores familiares de adolescentes ante la COVID-19, mediante un estudio longitudinal (evaluando primero a las 2-3 semanas del inicio del estado de alarma y después tras 8 semanas de su instauración en España). Participaron 32 progenitores de adolescentes. Tras aceptar participar, se evaluó: clima familiar, satisfacción vital, regulación emocional, resiliencia y psicopatología. Se realizaron modelos de análisis comparativo cualitativo de conjuntos difusos (fsQCA). Nuestros…
