Ischemic preconditioning (PC) has been proposed as an endogenous form of protection against-ischemia reperfusion injury. We have shown that PC does not prevent postischemic dysfunction in the aging heart. This phenomenon could be due to the reduction of cardiac norepinephrine release, and it has also been previously demonstrated that age-related decrease of(More)
BACKGROUND AND AIMS We investigated the prevalence of visual impairment (VI), its determinants and its association with Activities of Daily Living (ADL), Instrumental Activities of Daily Living (IADL), Gross Mobility (GM) and 6-year mortality in elderly subjects. A cross-sectional survey in a large population randomly selected in 1992 with a 6-year(More)
BACKGROUND The authors presented their experience in regenerative surgery of post-traumatic lower extremity ulcers, evaluating the effects related to the use of Enhanced Stromal Vascular Fraction (e-SVF) and Fat Grafting with Platelet rich Plasma (PRP). The authors compared the results of two control groups. METHOD The analysis involved 20 patients aged(More)
Coronary artery disease is the leading cause of death in industrialized countries for people older than 65 years of age. The reasons are still unclear. A reduction of endogenous mechanisms against ischemic insults has been proposed to explain this phenomenon. Cardiac ischemic preconditioning represents the most powerful endogenous protective mechanism(More)
Background Immediate implant reconstruction after a conservative mastectomy is an attractive option made easier by prosthetic devices. Titanized polypropylene meshes are used as a hammock to cover the lower lateral implant pole. We conducted a prospective nonrandomized single-institution study of reconstructions using titanium-coated meshes either in a(More)
For people with cervical spinal cord injury (SCI), access to computers can be difficult, thus several devices have been developed to facilitate their Disorders of consciousness (DOC) are difficult to classify. The degree of consciousness varies from coma to vegetative state or unresponsive wakefulness syndrome (UWS) and minimally conscious state. Correct(More)
BACKGROUND The aim was to investigate the ability of insulin to modulate the response to beta-adrenergic action on myocardial contractility, assessed as percentage changes of developed tension, in isolated rat papillary muscle. METHODS Dose-response curves for isoproterenol, calcium, and forskolin were constructed in an incremental fashion with the(More)
BACKGROUND Preinfarction angina, a clinical equivalent of ischemic preconditioning, seems to protect against in-hospital death, cardiogenic shock, and the combined endpoints in adult but not in elderly patients with acute myocardial infarction. Experimental evidence indicates that caloric restriction may restore ischemic preconditioning in aged animals. (More)
Editing spatially-varying appearance is commonplace in most graphics applications. In this paper, we focus on materials whose appearance is described by BRDFs or BSSRDFs, with parameters specified by textures, and with local frame perturbations, namely bump, normal and tangent maps. Editing these materials amounts to editing the textures that encode the(More)
UNLABELLED Direct-to-implant breast reconstruction can be achieved more easily by means of soft-tissue replacement devices such as dermal matrices and synthetic meshes. The feasibility of a subcutaneous approach has been recently investigated by some studies with different devices functioning as implant support. Aim of this study is to analyze the long-term(More)
