Gender Differences in the Presentation and Outcomes of Hospitalized Patients With COVID-19

2021

Gender-related differences in COVID-19 clinical presentation, disease progression, and mortality have not been adequately explored. We analyzed the clinical profile, presentation, treatments, and outcomes of patients according to gender in the HOPE-COVID-19 International Registry. Among 2,798 enrolled patients, 1,111 were women (39.7%). Male patients had a higher prevalence of cardiovascular risk factors and more comorbidities at baseline. After propensity score matching, 876 men and 876 women were selected. Male patients more often reported fever, whereas female patients more often reported vomiting, diarrhea, and hyposmia/anosmia. Laboratory tests in men presented alterations consistent w…

Contraddizioni urbanistiche della Zona Espansione Nord 2 a Palermo

2008

Viene sviluppata una lettura del quartiere ZEN di Palermo sulla base di conoscenze dirette vissute nel periodo di formazione del progetto. Dal testo si evince come il progetto voleva riproporre le dimensioni dell’insula del centro storico di Napoli. Gli errori principali appaiono essere l’accentuato isolamento che il quartiere ha subito nel tempo, il rapporto che le costruzioni hanno con l’impianto viario, l’assenza di servizi della vita collettiva. I rimedi adottati dal Prg di Palermo accentuano l’isolamento affidando al diradamento la possibilità dell’integrazione, mentre sarebbe più opportuno produrre un contesto di maggiore densità capace di assorbire lo ZEN nella città esistente anche …

Evolutionary psychological consumer research:Bold, bright, but better with behavior

2020

Abstract This special issue includes state-of-the-art papers that leverage various theories from evolutionary psychology (EP) to shed light on important consumption-related phenomena. Our guest editorial provides an overview of this EP-based consumer research, highlighting the key content, common denominators, and significant strengths of the articles. The papers cover a wide variety of topics, characteristic of evolutionary-informed research, that we structure around the following three themes: (1) Mating, marketing, and meaningful motivating forces, (2) Conspicuous consumption and salient signs of “showing off,” and (3) Human hormones and biologically-based business research. We close our…

Análisis de los factores que influyen en el proceso de creación de una cooperativa de trabajo asociado.

2006

Este trabajo pretende contribuir al conocimiento existente sobre el proceso de creación de cooperativas de trabajo asociado (CTA) a partir de la aplicación de un método inductivo-deductivo como es la Teoría Fundamentada. Para ello se han realizado un total de 37 entrevistas en profundidad con los socios-promotores de CTA creadas en el periodo 2001-2002, todas ellas localizadas en la Comunidad Valenciana (España). Como resultado de la aplicación de la metodología se han identificado un total de 29 códigos substantivos o factores que influyen en el comportamiento de los socios fundadores en cada una de las fases del proceso de creación de la empresa. This paper aims to contribute to existing …

Temperature-induced self-assembly of degalactosylated xyloglucan at low concentration

2015

Xyloglucan is a natural polysaccharide having a cellulose-like backbone and hydroxyl groups-rich side-chains. In its native form the polymer is water-soluble and forms gel only in presence of selected co-solutes. When a given fraction of galactosyl residues are removed by enzymatic reaction, the polymer acquires the ability to form a gel in aqueous solution at physiological temperatures, a property of great interest for biomedical/pharmaceutical applications. This work presents data on the effect of a temperature increase on degalactosylated xyloglucan dispersed in water at concentration low enough not to run into macroscopic gelation. Results obtained over a wide interval of length scales …

Halogen bonding stabilizes a cis-azobenzene derivative in the solid state : A crystallographic study

2017

Crystals oftrans- andcis-isomers of a fluorinated azobenzene derivative have been prepared and characterized by single-crystal X-ray diffraction. The presence of F atoms on the aromatic core of the azobenzene increases the lifetime of the metastablecis-isomer, allowing single crystals of thecis-azobenzene to be grown. Structural analysis on thecis-azobenzene, complemented with density functional theory calculations, highlights the active role of the halogen-bond contact (N...I synthon) in promoting the stabilization of thecis-isomer. The presence of a long aliphatic chain on the azobenzene unit induces a phase segregation that stabilizes the molecular arrangement for both thetrans- andcis-i…

Xyloglucan-based hydrogel films for wound dressing: Structure-property relationships

2017

Thin xyloglucan-based hydrogel films have been synthetized and characterized in the prospect of producing wound dressings. Polyvinyl alcohol (PVA) and glycerol (Gro) were added to have an optimal combination of softness, conformability and resilience. Physical hydrogels have been transformed into permanent covalent hydrogels by reaction with glutaraldehyde (GA). Network structure-process-property relationships are discussed on the account of the results of several complementary characterizations: FTIR, rheology, thermal analysis, morphological analysis, moisture retention and swelling measurements. Selected formulations were also subjected to preliminary in vitro cytotoxicity tests. The phy…

Cu-substituted lanthanum ferrite perovskites: Preparation, characterization and photocatalytic activity in gas-solid regime under simulated solar lig…

2016

Lanthanum orthoferrites LaFeO3 nanopowders doped with 20 mol% of Sr and 0-10-20 mol% of Cu were prepared by citrate auto-combustion synthesis and investigated in terms of crystal structure, morphology, surface area and optical properties by using several characterization techniques. The band gap energy values were found to range from 2.35 eV for LaFeO3 to 1.86 eV for the samples with the highest content of copper, this trend reflects the decrease of the particle size. All powders showed photocurrent response, the highest photocurrent was obtained for undoped orthoferrite calcined at 600°C. Their physical-chemical properties were related to photoelectrochemical behaviour. The the position of…
