Work-family conflict and its relations to well-being: the role of personality as a moderating factor
2003
Contains fulltext : 63496.pdf (Publisher’s version ) (Closed access) The aim of the present study was to examine the role of the Big Five personality dimensions as possible moderating factors between two types of work–family conflicts: work interference with family (WIF); and family interference with work (FIW); and their relationship to well-being in the domains of work and family generally as well. The participants were fathers (n=296) who took part in a national family research project in the Netherlands in 1995. All fathers were employed full-time. The results showed that emotional stability moderated the relationships between WIF and job exhaustion and between WIF and depression. In ad…
Abitare ad Agrigentum: riletture in corso dell’isolato II del Quartiere ellenistico-romano
2020
Si illustrano brevemente le problematiche attuali dell'indagine sul cd. Quartiere ellenistico-romano di Agrigento, focalizzando l'attenzione sull'isolato II. The current problems of the investigation into the Hellenistic-Roman district of Agrigento are briefly illustrated, focusing attention on block II.
Inkjet printing Ag nanoparticles for SERS hot spots
2018
A novel inkjet printing based approach is developed for the fabrication of a customizable platform on glass substrates allowing for surface enhanced Raman spectroscopy (SERS) detection of analytes up to single hot spots generated by the spontaneous aggregation of Ag nanoparticles (Ag NPs) in pL scale droplets. After drying the printed droplets under ambient conditions, trace amounts of the analyte can be detected by SERS given the proximity to NP hot spots. By employing alizarin (10-5M) as a model system and scaling the ink droplet volume from 1 nL to 10 pL, the absolute quantity of hot spots has been derived in the printed droplets allowing detecting up to a few molecules in proximity to i…
Receptor Activator of NF-kB (RANK) Expression in Primary Tumors Associates with Bone Metastasis Occurrence in Breast Cancer Patients
2011
Background\ud Receptor activator of NFkB (RANK), its ligand (RANKL) and the decoy receptor of RANKL (osteoprotegerin, OPG) play a pivotal role in bone remodeling by regulating osteoclasts formation and activity. RANKL stimulates migration of RANK-expressing tumor cells in vitro, conversely inhibited by OPG.\ud \ud Materials and Methods\ud We examined mRNA expression levels of RANKL/RANK/OPG in a publicly available microarray dataset of 295 primary breast cancer patients. We next analyzed RANK expression by immunohistochemistry in an independent series of 93 primary breast cancer specimens and investigated a possible association with clinicopathological parameters, bone recurrence and surviv…
Candida biofilms on implanted biomaterials: a clinically significant problem.
2006
In recent years there has been an increasing appreciation that microbial biofilms are ubiquitous, which has resulted in a number of studies on infectious diseases from a biofilm perspective. Biofilms are defined as structured microbial communities that are attached to a surface and encased in a matrix of exopolymeric material. A wide range of biomaterials used in clinical practice have been shown to support colonization and biofilm formation by Candida spp., and the increase in Candida infections in the last decades has almost paralleled the increase and widespread use of a broad range of medical implant devices, mainly in populations with impaired host defenses. Formation of Candida biofil…
Beads of Acryloylated Polyaminoacidic Matrices Containing 5-Fluorouracil for Drug Delivery
2002
Spherical polymeric microparticles have been prepared by a reverse phase suspension polymerization technique. The starting polymer was alpha,beta-poly(N-2-hydroxyethyl)-DL-aspartamide (PHEA), partially derivatized with glycidylmethacrylate (GMA). PHEA-GMA copolymer (PHG) was crosslinked in the presence of N,N'-dimethylacrylamide (DMAA) or N,N'-ethylenebisacrylamide (EBA). 5-fluorouracil was incorporated into PHG-DMAA or PHG-EBA beads both during and after the crosslinking process. Swelling studies revealed a high affinity toward aqueous medium, influenced by the presence of 5-fluorouracil. The in vitro release study showed that the release rate depends on the chemical structure of the beads…
Enhanced In Situ Availability of Aphanizomenon Flos-Aquae Constituents Entrapped in Buccal Films for the Treatment of Oxidative Stress-Related Oral D…
2019
In recent years, the key role of oxidative stress in pathogenesis of oral diseases has been emphasized and the use of antioxidant agents has been encouraged. Aphanizomenon flos-aquae (AFA) is a unicellular blue-green alga with antioxidant and anti-inflammatory properties. The aim of this study was the formulation and characterization of mucoadhesive thin layer films loaded with AFA, finalized to the treatment of oxidative stress (OS)-related oral diseases. First, to enhance the bioavailability of AFA constituents, the raw food grade material was appropriately treated by a high frequency homogenization able to disrupt cell walls. Thus, Eudragit®
Gelchromatographie. 8. Mitt.: Vernetzte copolymere des vinylacetats
1969
Die Eigenschaften von vernetzten Copolymeren des Vinylacetats wurden in Abhangigkeit von den Herstellungsbedingungen gepruft. Als Vernetzungsmittel dienten Divinyladipat und Butandiol-(1.4)-divinylather. Mit homogen-vernetzten Gelen konnen Ausschlusmolekulargewichte bis etwa 4000 erzielt werden: zwischen dem spezifischen Gelbettvolumen und dem Ausschlusmolekulargewicht besteht eine lineare Beziehung. Die heterogen-vernetzende Copolymerisation des Vinylacetats in Gegenwart verschiedener inerter Verdunnungsmittel fuhrt zu Gelen mit Ausschlusmolekulargewichten uber 106. Die vernetzten Copolymeren wurden durch ihre scheinbare Dichte, durch die Aufnahme von Losungs- und Fallungsmitteln, durch di…
Regular 1-harmonic flow
2017
We consider the 1-harmonic flow of maps from a bounded domain into a submanifold of a Euclidean space, i.e. the gradient flow of the total variation functional restricted to maps taking values in the manifold. We restrict ourselves to Lipschitz initial data. We prove uniqueness and, in the case of a convex domain, local existence of solutions to the flow equations. If the target manifold has non-positive sectional curvature or in the case that the datum is small, solutions are shown to exist globally and to become constant in finite time. We also consider the case where the domain is a compact Riemannian manifold without boundary, solving the homotopy problem for 1-harmonic maps under some …
