Design ed eco-sostenibilità: le fibre vegetali in Sicilia tra tradizione ed innovazione
2012
Il dibattito sulla questione ambientale, sorto tra gli anni ‘60 e ‘70 del secolo scorso, con la formazione delle prime associazioni ambientaliste, ebbe come nodo centrale il rapporto tra economia e ambiente, nella sempre più evidente necessità di preservare la qualità del patrimonio naturale e nella consapevolezza che, essendo le risorse del pianeta tendenzialmente esauribili, dovessero essere rivisti ed equilibrati i modelli di sviluppo. Gli oggetti, secondo la lezione di Bruno Latour, simboleggiano stili di vita che comprendono al loro interno processi comunicativi e riguardano in ogni caso la sfera dell’informazione, dell’interazione, del ricordo e anche del desiderio. L’omologazione del…
Análisis de la bondad de múltiples indicadores para el diagnóstico de la adicción al cibersexo
2021
El uso de Internet con propósitos sexuales (p.e., visionado de pornografía o contacto sexual mediante chat o cámara web) resulta una práctica cada vez más generalizada. Si bien en la mayoría de los casos se realiza de forma recreativa, en algunas ocasiones puede sobrevenir compulsivo, incontrolado y asociado a deterioro funcional en varios ámbitos (adicción al cibersexo). Las escalas de las que disponemos para su diagnóstico se han visto limitadas a la hora de identificar estos pacientes debido a que algunos indicadores diagnósticos han perdido especificidad: por ejemplo, el tiempo online con fines sexuales parece no discriminar usuarios problemáticos debido al uso cada vez más intensivo de…
Current Trends in Advanced Alginate-Based Wound Dressings for Chronic Wounds
2021
Chronic wounds represent a major public health issue, with an extremely high cost worldwide. In healthy individuals, the wound healing process takes place in different stages: inflammation, cell proliferation (fibroblasts and keratinocytes of the dermis), and finally remodeling of the extracellular matrix (equilibrium between metalloproteinases and their inhibitors). In chronic wounds, the chronic inflammation favors exudate persistence and bacterial film has a special importance in the dynamics of chronic inflammation in wounds that do not heal. Recent advances in biopolymer-based materials for wound healing highlight the performance of specific alginate forms. An ideal wound dressing shou…
Signos y síntomas de adicción al cibersexo en adultos mayores
2019
El uso de Internet con objetivos sexuales resulta una práctica cada vez más generalizada en cualquier etapa vital. Si bien en la mayoría de casos el consumo se realiza de forma recreativa, en ocasiones éste puede sobrevenir compulsivo, incontrolado y asociado a un deterioro funcional en diversos ámbitos (adicción al cibersexo). Conocer los síntomas que caracterizan este cuadro clínico constituye una prioridad; sin embargo, disponemos de un pobre conocimiento acerca de su expresión en adultos mayores. Así, este trabajo se planteó con un doble objetivo: 1) analizar la prevalencia de adultos mayores en riesgo de desarrollar o que muestran un perfil patológico de uso del cibersexo y 2) elaborar…
Educational strategies on potential prescribers to implement correct use of genomic tests: the Italian experience.
2012
Abstract background Marketing pressures, regulatory policies, clinical guidelines, and consumer’s demand all affect health care providers' knowledge and use of health-related genetic tests sold and/or advertised to consumers. A survey on health care providers’ and consumers’ awareness, perceptions, and use of direct-to-consumer personal genomic tests, conducted in USA in 2008, suggested a strong need for education of health practitioners. A similar survey, administered among Italian general practitioners (GPs), has documented that the 85% of interviewers reported the need for specific training on predictive tests’ prescription. Based on these premises, the Italian Health Ministry has introd…
Neuropeptide Y (NPY)-like immunoreactivity in the guinea pig pineal organ.
1986
Relatively little is known about mammalian pineal neuropeptides. In the present study neuropeptide Y-like immunoreactivity (NPY-LI) was examined in the guinea pig pineal gland. NPY-LI was restricted to few intrapineal nerve fibers of faint fluorescence intensity. They showed no preferential localization with regard to the different pineal portions. As catecholaminergic fibers are abundant in the guinea pig pineal gland, the scarcity of NPY-LI fibers indicates that in the pineal colocalization of noradrenaline and NPY-LI is not a regular feature, in contrast to other organs. The possibility exists that in the pineal NPY-LI fibers are not of peripheral sympathetic but of central origin.
Pro-enkephalin opioid peptides are abundant in porcine and bovine splenic nerves, but absent from nerves of rat, mouse, hamster, and guinea-pig spleen
1995
The opioidergic innervation of the mammalian spleen and possible species differences were investigated. Light-microscopic immunohistochemistry revealed that splenic nerves of bovine and porcine spleen, but not of rat, mouse, hamster and guinea-pig spleen contained proenkephalin-derived opioidergic innervation. Immunoreactivity to both prodynorphin and pro-opiomelanocortin was absent from splenic nerves. In bovine and porcine spleen, fibers immunoreactive for met-enkephalin, met-enkephalin-Arg-Phe, met-enkephalin-Arg-Gly-Leu, leu-enkephalin and peptide F formed perivascular plexus, traveled in trabecular connective tissue, and extended into the capsule. Spatial relationships with immune cell…
Influence of nerve growth factor in endometriosis-associated symptoms
2011
To investigate the role of the nerve growth factor (NGF) in the development of dysmenorrhea/pelvic pain in patients with endometriosis, we performed a prospective, clinical, blind study. Peritoneal fluids (PFs) were obtained from patients with histologically proven endometriosis. Patients with endometriosis were divided into 7 different groups depending on their preoperative pain score and symptomatology: patients with no pain, patients with minimal pain (dysmenorrhea, pelvic pain, or both), and patients with severe pain (dysmenorrhea, pelvic pain, or both) and were used for the neuronal growth assay with cultured chicken dorsal root ganglia (DRG) and for Western blot analyses. Dorsal root …
Effects of combined hormone replacement therapy or its effective agents on the IGF-1 pathway in skeletal muscle.
2010
Objectives To investigate the effects of combined hormone replacement therapy (HRT) and its effective agents on the IGF-1 signaling pathway. Design and methods To examine the effects of HRT on skeletal muscle in vivo, we utilized pre- and post-intervention samples from a randomized double blinded trial with 50–57-year-old women. The intervention included the year-long use of either HRT preparation (2 mg 17β-estradiol, E2; 1 mg norethisterone acetate, NETA, n = 10) or placebo (CO, n = 9). Microarray technology and quantitative PCR (qPCR) were used to study the expression of insulin-like growth factor I (IGF-1) and its splice variants as well as IGF-1 receptor, Akt1, mTOR, FOXO1, FOXO3, atrog…
Fracture strenght and ribbond fibers: In vitro analysis of mod restorations
2023
Ribbond fibers are supposed to be a reinforcing material in restoration of compromised teeth. This study aims to compare MOD restorations with and without Ribbond Fiber in terms of fracture strength under axial loading; to identify the minimum depth of MO
