The regeneration in the peripheral nervous system is often incomplete and the treatment of severe lesions with nerve tissue loss is primarily aimed at recreating nerve continuity. Guide tubes of various types, filled with Schwann cells, stem cells, or nerve growth factors are attractive as an alternative therapy to nerve grafts. In this study, we evaluated(More)
To determine the prognostic significance of ambulatory blood pressure, we prospectively followed for up to 7.5 years (mean, 3.2) 1187 subjects with essential hypertension and 205 healthy normotensive control subjects who had baseline off-therapy 24-hour noninvasive ambulatory blood pressure monitoring. Prevalence of white coat hypertension, defined by an(More)
This study was aimed at improving the performance of standard electrocardiographic criteria of left ventricular hypertrophy (LVH) in essential hypertension using echocardiographic left ventricular mass as reference. In 923 white, untreated hypertensive subjects (mean age 51, prevalence of echocardiographic LVH 34%), sensitivity of electrocardiographic(More)
OBJECTIVES We examined the prognostic significance of concentric remodeling of the left ventricle in patients with essential hypertension and normal left ventricular mass on echocardiography. BACKGROUND An echocardiographic pattern of concentric remodeling of the left ventricle has been associated with clinical features of increased cardiovascular risk,(More)
Abnormal connective tissue proliferation following muscle degeneration is a major pathological feature of Duchenne muscular dystrophy (DMD), a genetic myopathy due to lack of the sarcolemmal dystrophin protein. Since this fibrotic proliferation is likely to be a major obstacle to the efficacy of future therapies, research is needed to understand and prevent(More)
Recently our group demonstrated the myogenic capacity of human CD133(+) cells isolated from peripheral blood when delivered in vivo through the arterial circulation into the muscle of dystrophic scid/mdx mice. CD133(+) stem cells express the adhesion molecules CD44, LFA-1, PSGL-1, alpha4-integrins, L-selectin, and chemokine receptor CCR7. Moreover these(More)
Duchenne muscular dystrophy (DMD) is a hereditary disease caused by mutations that disrupt the dystrophin mRNA reading frame. In some cases, forced exclusion (skipping) of a single exon can restore the reading frame, giving rise to a shorter, but still functional, protein. In this study, we constructed lentiviral vectors expressing antisense(More)
OBJECTIVE To assess the role of blood pressure in the association between cigarette smoking and left ventricular mass in male and female subjects with essential hypertension. DESIGN A case-control study with matching ratio of 1:4. PATIENTS AND METHODS We studied 115 heavy smokers (> or = 20 cigarettes/day; 91 men) and 460 non-smokers (364 men) with(More)
BACKGROUND In essential hypertension, a blunted or absent nocturnal fall in blood pressure (BP) may be associated with increased target organ damage. In this case-control study, we tested the hypothesis that an association exists between a blunted or absent nocturnal fall in BP and future cardiovascular morbid events in patients with essential hypertension.(More)
Hypertension is a risk factor for sudden cardiac death, and some data indicate that frequent and complex ventricular arrhythmias may be additional risk markers in hypertensive individuals. We investigated the relation between ventricular arrhythmias and the persistence of increased blood pressure levels over 24 hours in subjects with essential hypertension.(More)
