No effects of low-intensity endurance exercise on muscle necrosis in the diaphragm of mdx mice
Duchenne muscular dystrophy (DMD) is characterized by progressive skeletal muscle weakness. We have previously shown that low-intensity endurance training prevented muscle damage (Frinchi et al, Int J Sports Med 2014). Since the effects of low-intensity endurance training on the the diaphragm in the mdx mouse model are unknown, in the same animals we investigated Cx39 protein levels (Western blotting) in homogenates of the diaphragm before and after training. Mdx and wild-type (WT) mice were randomly assigned to sedentary (mdx-S, n=17; WT-S, n=19) or trained (mdx-EX, n=14; WT-EX, n=16) groups. Low-intensity endurance training (running on a wheel) was done 5 days/week for 6 weeks at progress…

Valutazione della performance fisica e del livello di autonomia personale nel soggetto anziano.
Con l’invecchiamento della popolazione e l’aumento delle patologie croniche, sono necessari interventi mirati a mantenere la salute e contenere i costi sanitari. La performance fisica dell’anziano si riduce con l’età per la normale riduzione della massa e della potenza muscolare, ma l’allenamento di intensità moderata è utile e migliora anche la performance cognitiva. Negli anziani, programmi di riabilitazione e di home care possono essere utili a prevenire le cadute, l’ospedalizzazione ed i ricoveri in casa di riposo. Il test da sforzo è il metodo classico per valutare la performance fisica, ma informazioni complementari e clinicamente importanti sono fornite dal test del cammino dei 6 min…
Cardio-respiratory monitoring during sleep
Nocturnal intermittent hypoxia predicts prevalent hypertension in the European Sleep Apnoea Database cohort study.
Systemic hypertension is associated with obstructive sleep apnoea syndrome (OSAS) but the pathophysiological mechanisms are incompletely understood. A collaborative European network of 24 sleep centres established a European Sleep Apnoea Database to evaluate cardiovascular morbidity associated with OSAS.11 911 adults referred with suspected OSAS between March 2007 and September 2013 underwent overnight sleep studies, either cardiorespiratory polygraphy or polysomnography. We compared the predictive value of the apnoea–hypopnoea index (AHI) and 4% oxygen desaturation index (ODI) for prevalent hypertension, adjusting for relevant covariates including age, smoking, obesity, dyslipidaemia and d…

GENETIC ASPECTS OF HYPERTENSION AND METABOLIC DISEASE IN THE OBSTRUCTIVE SLEEP APNOEA-HYPOPNOEA SYNDROME.
Considerable evidence is available in support of an independent association between obstructive sleep apnoea syndrome (OSAS) and cardiovascular disease, which is particularly strong for systemic arterial hypertension and growing for ischaemic heart disease, stroke, heart failure, atrial fibrillation and cardiac sudden death. The pathogenesis of cardiovascular disease in OSAS is not completely understood but likely to be multifactorial, involving a diverse range of mechanisms including sympathetic nervous system overactivity, selective activation of inflammatory molecular pathways, endothelial dysfunction, abnormal coagulation and metabolic dysregulation, the latter particularly involving in…

Effects of mild aerobic exercise training on the diaphragm in mdx mice
Mild endurance exercise training positively affects limb skeletal muscle in the mdx mice model of Duchenne Muscular Dystrophy (DMD). However, few and controversial data are available on the effects of mild exercise training on the diaphragm of mdx mice. The diaphragm was examined in mdx and wild type mice either under sedentary conditions (mdx-SD, WT-SD) or during mild exercise training (mdx-EX, WT-EX). At baseline and after 30 and 45 days of training (5 d/wk for 6 weeks), diaphragm muscle morphology and Cx39 protein were assessed. In addition, tissue levels of the chaperonin Hsp60 were measured at the same time points in gastrocnemius, quadriceps and diaphragm in each experimental group. A…

Cigarette smoke increases TLR4 and modifies LPS mediated responses in airway epithelial cells.
Airway epithelium is emerging as a regulator of innate immune responses to a variety of insults including cigarette smoke. The main goal of this study was to explore the effects of cigarette smoke extracts (CSE) on Tolllike receptor (TLR) expression and activation in a human bronchial epithelial cell line (16-HBE). The CSE increased the expression of TLR4 and the lipopolysaccharide (LPS) binding, the nuclear factor-jB (NF-jB) activation, the release of interleukin-8 (IL-8) and the chemotactic activity toward neutrophils. It did not induce TLR2 expression or extracellular signal-regulated signal kinase 1/2 (ERK1/2) activation. The LPS increased the expression of TLR4 and induced both NF-jB a…

Conseguenze metaboliche dell'ipossia
Riassunto La sopravvivenza in condizioni di ipossia dipende dall’attivazione di processi cellulari complessi, con risposte di adattamento (quali il potenziamento del trasporto di O2 attraverso l’aumento dell’eritropoiesi, l’attivazione dell’angiogenesi e l’aumento della glicolisi anaerobica) e l’inibizione di processi metabolici che richiedono alta disponibilità di O2. Ciò consente di mantenere l’omeostasi energetica anche in condizioni di ridotta disponibilità di O2. Nel modello fisiologico del soggiorno ad alta quota si verificano riduzione di peso e della capacità di lavoro associata a riduzione della massa muscolare, che però sono reversibili al ripristino di condizioni di normossia. Le…

Small airways in sedentary and endurance-trained dystrophic (mdx) mice.
The effects of mild endurance exercise training on the small airways in mdx mice are unknown. We compared epithelial thickness and turnover, apoptosis, and stress marker expression in small airways of mdx mice and wild-type (WT) controls, at rest and during exercise training. Mdx and WT mice were randomly assigned to sedentary (mdx-S, n=17; WT-S, n=19) or trained (mdx- EX, n=14; WT-EX, n=16) groups. Low-intensity endurance training (running on a wheel) was done 5 d/wk for 6 wk at progressively increasing speed (rpm from 16 to 24) and time (15 min to 1 h). Lungs were processed for light microscopy and periodic acid Schiff (PAS) staining. Hsp60 and PCNA were quantified by immunohistochemistry…

Effects of rowing training on airway responsiveness in asthmatics
We previously reported that after a short course of rowing training the responsiveness to methacholine (Mch) in the absence of deep inspiration (DI) decreased in healthy subjects. We assessed whether a similar beneficial effect of exercise on airway responsiveness could occur in asthmatics. Nine patients (M/F: 3/6; mean age±SD: 24±2 yrs) with mild untreated asthma (FEV(1): 100±7.4% pred, FEV(1)/VC 90±6.5%) underwent a series of single dose Mch bronchoprovocations in the absence of DI in the course of a indoor rowing training consisted of two to three sessions per week for 10 weeks (total 28 sessions). Each session included a warm-up period for 20 min (running and stretching), and a specific…

Sleep-disordered breathing in the elderly
Purpose: The prevalence of sleep-disordered breathing (SDB) increases with aging. SDB is a risk of hypertension, and both might lead to cognitive decline. However, the role of SDB and hypertension on the pathogenesis of age-related cognitive decline remains unclear. We examined the effects of these two diseases on cognitive function in elderly adults.

Effects of acute CPAP application on baroreflex control of heart rate during sleep in severe obstructive sleep apnea.
Baroreflex control of heart rate during sleep (baroreflex sensitivity; BRS) has been shown to be depressed in obstructive sleep apnoea (OSA), and improved after treatment with continuous positive airway pressure (CPAP). Whether CPAP also acutely affects BRS during sleep in uncomplicated severe OSA is still debatable. Blood pressure was monitored during nocturnal polysomnography in 18 patients at baseline and during first-time CPAP application. Spontaneous BRS was analysed by the sequence method, and estimated as the mean sequence slope. CPAP did not acutely affect mean blood pressure or heart rate but decreased cardiovascular variability during sleep. Mean BRS increased slightly during CPAP…
