Long-Term Calorie Restriction Enhances Cellular Quality-Control Processes in Human Skeletal Muscle

2015

Calorie restriction (CR) retards aging, acts as a hormetic intervention, and increases serum corticosterone and HSP70 expression in rodents. However, less is known regarding the effects of CR on these factors in humans. Serum cortisol and molecular chaperones and autophagic proteins were measured in the skeletal muscle of subjects on CR diets for 3-15 years and in control volunteers. Serum cortisol was higher in the CR group than in age-matched sedentary and endurance athlete groups (15.6 ± 4.6 ng/dl versus 12.3 ± 3.9 ng/dl and 11.2 ± 2.7 ng/dl, respectively; p ≤ 0.001). HSP70, Grp78, beclin-1, and LC3 mRNA and/or protein levels were higher in the skeletal muscle of the CR group compared to…

Serum uric acid is not independently associated with plasma renin activity and plasma aldosterone in hypertensive adults

2017

Background and Aims In experimental investigations conducted in rats, raising serum uric acid (SUA) levels resulted in the stimulation of intrarenal renin expression. Studies in humans exploring the association of SUA with plasma renin activity (PRA) yielded conflicting results. Moreover, little is known about the relationship of SUA with plasma aldosterone concentration (PAC). The study aimed to assess the relationship between SUA levels, PRA, and PAC and the influence of age, gender, body mass index (BMI), and hyperuricemia on these relationships in subjects with essential hypertension (EH). Methods and Results We enrolled 372 hypertensive patients (mean age 45 ± 12 years, men 67%) with u…

Plasma aldosterone and its relationship with left ventricular mass in hypertensive patients with early-stage chronic kidney disease

2014

Plasma aldosterone concentrations (PACs) are often increased in the advanced stages of chronic kidney disease (CKD); however, PAC has not been fully investigated in early CKD. Moreover, little is known about the relationship between aldosteronemia and left ventricular (LV) mass in subjects with mild-to-moderate CKD. The study objectives were to analyze PAC, LV mass (LVM), LV geometry and their relationships, in a group of hypertensive patients with stage I-III CKD. One hundred ninety-five hypertensive patients with stage I-III CKD were enrolled and compared with a control group of 82 hypertensive patients without renal dysfunction. LVM was higher in subjects with CKD than in the control gro…

RELATIONSHIPS OF SERUM URIC ACID WITH PLASMA RENIN ACTIVITY AND PLASMA ALDOSTERONE IN UNTREATED HYPERTENSIVE SUBJECTS

2013

In experimental studies conducted in rats, raising serum uric acid (SUA) levels resulted in stimulation of intrarenal renin expression. Studies in humans exploring the association of SUA with plasma renin activity (PRA) yielded conflicting results. Moreover, little is known about the relationship between plasma aldosterone concentration (PAC) and SUA. The aim of our study was to analyse the relationships between SUA, PRA and PAC and the influence of age and gender on these relationships in a group of subjects with primary hypertension. We enrolled 281 patients (men 59%), with untreated primary hypertension and normal renal function. The study population wad divided in two subgroups on the b…

Effects of anti-aldosteronic agents in resistant hypertension

2011

Hypertension is defined resistant (or refractory) when it is not possible to reach the target values of blood pressure despite the contemporary use of three antihypertensive drugs at optimised dosage (1). Today difficult control of hypertension is more and more frequent in clinical practice. In recent years the role of anti-aldosteronic agents has appeared useful in the treatment of resistant hypertension; this condition seems to be related to the increase of the mean age. Subjects suffering from resistant hypertension mostly show an isolated high systolic pressure. In addition to advanced age, factors commonly associated are: increased levels of aldosterone and intravascular volume, chroni…

Introduction: In experimental studies conducted in rats, raising serum uric acid (SUA) levels resulted in stimulation of renin expression. Studies in humans exploring the association of SUA with plasma renin activity (PRA) yielded conflicting results. Moreover, little is known about the relationship between plasma aldosterone concentration (PAC) and SUA. Aim: To analyse the relationships between SUA, PRA and PAC in a group of subjects with primary hypertension. Methods: We enrolled 372 patients (mean age 45 ± 12 years; women 33 %), with untreated primary hypertension, with normal renal function and without cardiovascular complications. Results: Spearman’s rank-correlation analyses showed th…
