Effects of Physical Exercise on Inflammatory Markers of Atherosclerosis
2011
It is well established that physically fit individuals have a reduced risk of developing CVD (cardiovascular disease) and other age-related chronic disorders. Regular exercise is an established therapeutic intervention with an enormous range of benefits. Chronic low-grade systemic inflammation may be involved in atherosclerosis, diabetes and in pathogenesis of several chronic pathological conditions; recent findings confirm that physical activity induces an increase in the systemic levels of a number of cytokines and chemokines with anti-inflammatory properties. The possibility that regular physical exercise exerts anti-inflammation activity, being the interaction between contracting muscle…
Pathogenetic Mechanisms of Hypertension-Brain-Induced Complications: Focus on Molecular Mediators.
2021
There is growing evidence that hypertension is the most important vascular risk factor for the development and progression of cardiovascular and cerebrovascular diseases. The brain is an early target of hypertension-induced organ damage and may manifest as stroke, subclinical cerebrovascular abnormalities and cognitive decline. The pathophysiological mechanisms of these harmful effects remain to be completely clarified. Hypertension is well known to alter the structure and function of cerebral blood vessels not only through its haemodynamics effects but also for its relationships with endothelial dysfunction, oxidative stress and inflammation. In the last several years, new possible mechani…
Non-coding RNAs and other determinants of neuroinflammation and endothelial dysfunction: regulation of gene expression in the acute phase of ischemic…
2021
Ischemic stroke occurs under a variety of clinical conditions and has different pathogeneses, resulting in necrosis of brain parenchyma. Stroke pathogenesis is characterized by neuroinflammation and endothelial dysfunction. Some of the main processes triggered in the early stages of ischemic damage are the rapid activation of resident inflammatory cells (microglia, astrocytes and endothelial cells), inflammatory cytokines, and translocation of intercellular nuclear factors. Inflammation in stroke includes all the processes mentioned above, and it consists of either protective or detrimental effects concerning the “polarization” of these processes. This polarization comes out from the intera…
4. Inflammation, Endothelial Dysfunction and Arterial Stiffness as Therapeutic Targets in Cardiovascular Medicine.
2016
In the last decades, many factors thought to be associated with the atherosclerotic process and cardiovascular events have been studied, and some of these have been shown to correlate with clinical outcome, such as arterial stiffness, endothelial dysfunction and immunoinflammatory markers. Arterial stiffness is an important surrogate marker that describes the capability of an artery to expand and contract in response to pressure changes. It can be assessed with different techniques, such as the evaluation of PWV and AIx. It is related to central systolic pressure and it is an independent predictor of cardiovascular morbidity and mortality in hypertensive patients, type 2 diabetes, end-stage…
INVERSE RELATIONSHIP BETWEEN CHOROIDAL THICKNESS AND SUBCLINICAL RENAL DAMAGE IN ESSENTIAL HYPERTENSION
2018
The introduction in last years of advanced techniques of optical coherence tomography (OCT) has greatly increased our understanding of the choroid, that is the most important vascular layer of the eye. Our study was aimed to assess choroidal thickness by using Swept-Source OCT (SS-OCT) in essential hypertensive patients (EHs) with and without subclinical renal damage (SRD). We enrolled 100 EHs of which 65 without kidney damage and 35 with SRD. In all the participants SS-OCT and a routine biochemical workup were performed. Glomerular filtration rate (GFR) was estimated by the CKD-EPI equation (eGFR). SRD was defined, by the presence of microalbuminuria or eGFR between 30 and 60 mL/min/1.73 m…

Association between sensorineural hearing loss and sleep-disordered breathing: Literature review
2015
The cochlea is especially sensitive to circulatory alterations because it is supplied by a single terminal artery and lacks adequate collateral blood supply. To examine the putative association between Sensorineural Hearing Loss (SNHL) and Sleep Disordered Breathing (SDB) through the literature review is very interesting. In fact these medical disorders usually are associated to cerebral circulatory alterations resulting in hypoxia, acute hemodynamic change, and decreased cerebral blood flow, because the Sleep Disorder Breathing (SDB), for example OSAHS (Obstructive Sleep Apnea Hypopnea Syndrome), is characterized by periodic hyposia/reoxygenation. These noxious stimuli can, in turn, activa…
Il Trasferimento Energetico Capacitivo Resistivo (TECAR) nella terapia dell’Induratio Penis Plastica: studio pilota di fase uno sulla tollerabilità, …
2013
Our phase-one prospective study wants to evaluate the safety and tolerability of TECAR therapy in the treatment of Peyronie’s disease. From June 2011 to September 2012 we enrolled 70 patients. Each patient had been previously subjected to andrological examination, to a questionnaire for the evaluation of IPP and ED, and the SF-36 (V1) for the evaluation of the general state of health. The evaluation of pain was made using the VAS scale of pain. Every patient was subjected to TECAR treatment of the fibrotic plaque (both in resistive mode and in capacitive mode) for a total of three sessions carried out on consecutive days. We recorded a good compliance by patients; none of them reported side…
Declines in Sexual Activity and Function Predict Incident Health Problems in Older Adults: Prospective Findings from the English Longitudinal Study o…
2020
The objective of this study was to investigate cross-sectional and longitudinal associations between declines in sexual activity and function and health outcomes in a large population-based sample of older adults. Data were from 2577 men and 3195 women aged ≥ 50 years participating in the English Longitudinal Study of Ageing. Past-year changes in sexual desire, frequency of sexual activity, and ability to have an erection (men)/become sexually aroused (women) were assessed at baseline by self-completion questionnaire. Health outcomes (self-rated health, limiting long-standing illness, doctor-diagnosed diseases of the vascular system, and cancer) were self-reported at baseline (2012/2013) an…
Role of Testosterone in Male Sexual Impotent Patients
1985
The role of biological factors contributing to development of sexual dysfunction (SD) has given rise to controversy over many years. Whereas a broad consensus is achieved that schizophrenia and affective psychoses have a biological etiology, such mechanisms receive less acceptance for SD. Conversely, the observation that SD is frequently a concomitant factor in affective illness is subject of current interest in research. For both diseases SD and affective disorder impaired gonadal function is documented (Rubin et al., 1981; Benkert and Holsboer, 1984), whereas both disorders may well occur independantly from each other. In the following section we outline briefly some of the presently avai…
