Impiego di granelle di leguminose in alternativa alla soia nella produzione di carne ovina biologica

2009

Use of legume grains in substitution of soybean meal in organic lamb meat production. This study aimed to evaluate the effects of replacing soybean meal in the diet with alternative legume grains without GMO presence and at low aflatoxin risk, on the growth and carcass and meat quality traits of lambs. After weaning at 66±6 d of age, 28 male Comisana lambs were divided into 4 groups and gradually adapted to diets over a 15-d period. Until slaughter at 129±6 d of age, each group received ad libitum pelleted alfalfa hay and concentrates differing for the protein source: chickpeas (CP), faba beans (FB), peas (PE) and soybean meal (SM). Lambs growth and carcasses weight were not modified by the…

Diversity and conservation in wild and cultivated Capparis in Sicily

1997

The taxonomy, distribution and ecology of the polymorphic Capparis spinosa L. in Sicily are discussed. C. spinosa subsp. rupeslris (Sibth. & Sm.) Nyman , a leathery-Ieaved, pendulous-branched shrub is widespread on carbonate, volcanic and gypsaceous outcrops. Subsp. spinosa, a thorny chamaephyte or hemicryptophyte with creeping branches, is mainly distributed in south-central parts of Sicily, on clay and natric soils under xerophilous conditions. Attention is drawn to a remarkable environment-induced variation within the latter subspecies. The heterogeneity of the cultivated forms of subsp. rupestris on the island of Pantelleria (Strait of Sicily) appears to be linked to crossing and in…

Role of Matrix Metalloproteinases 2,9 (MMP-2,-9), Orphanin FQ and Others Peptides in Vascular Tone of Human Umbilical Cord at Term

2008

Umbilical cord is the structure that connects the fetus to the placenta. Umbilical cord at term is made of three vessels surrounded by the Wharton's Jelly, a mocous connective tissue rich in glycosaminoglycans, proteoglycans and different types of collagens and other microfibrils, which are responsible for its elasticity and its mechanical properties. Umbilical cord seems to lack any capillaries or lymphatics and umbilical vessels are unique in lacking any innervation of the vascular tone, and the expression of some enzymes responsible for the remodelling of the extracellular matrix. Trough immunihistochemistry we investigated the expression of matrix metallo-peptidase 2 and 9 (MMP-2, MMP-9…

Matrix metalloproteinase-2 matrix metalloproteinase-9 and inducible nitric oxide synthase in oral leukoplakia: Immunohistochemistry and RT-PCR analys…

2008

Oral leukoplakia is the most common and potentially malignant disorder of the oral mucosa. The definition of leukoplakia given by the World Health Organization is "a white plaque that cannot be characterized either from a clinical or from a histopathological point of view", thus the diagnosis of leukoplakia is based on the exclusion of other lesions of the oral mucosa. We believe it is necessary to identify molecular and immunohistochemical parameters that can contribute to discriminating between the different leukoplakia clinical subtypes coded by the epidemiology. In the present work we show the preliminary results of this research project. We investigated the expression of matrix metallo…

Human umbilical cord expresses several vasoactive peptides involved in the local regulation of vascular tone: protein and gene expression of Orphanin…

2011

Full-term human umbilical cord contains three blood vessels: two arteries coiled around a vein and surrounded by Wharton’s jelly, a mucous tissue with few mesenchymal stromal cells and abundant extracellular matrix. Umbilical vessels lack innervations, thus endothelial cells must play a role in the control of blood flow. The aim of this study was to investigate in human umbilical cord the expression of five peptides that could be involved in the regulation of vascular tone: Orphanin FQ, Oxytocin, Atrial Natriuretic Peptide (ANP), endothelial Nitric Oxide Synthase (eNOS) and inducible Nitric Oxide Synthase (iNOS). The expression of these molecules in full-term human umbilical cord …

Comportamento della eNOS e dell'iNOS nella genesi e mantwnimento delle ulcere venose degli arti inferiori

2019

Chronic venous insufficiency (CVI) and venous ulcers in the lower areas are widespread problems with a prevalence of 1% - 2% in the western population. The pathophysiology of this pathological manifestation is not yet fully clarified and it can be assumed that a multifactorial genesis should be considered. Certainly the high pressure values ​​in the peripheral venous system, the defective valves in the capillary network, the increase in permeability and capillary neogenesis (discharge of liquids in the extracellular compartment - + edema), the discharge of fibrinogen and the subsequent formation of a pericapillary fibrin cuff are the most important mechanisms related to hypoxia and skin isc…
