Central obesity and hypertension: the role of plasma endothelin. Am J Hypertens
1996
Hypertension and central obesity are two conditions closely linked, but the mechanisms responsible for obesity-associated hypertension are still unclear. In the last few years, several studies addressed the role of endothelin-1 (ET-1) in the development and maintenance of hypertension. This study was designed to evaluate plasma ET-1 in normotensive and hypertensive central obese subjects compared with a lean healthy group. Our final goal was to analyze the relationship between plasma ET-1, blood pressure, and left ventricular structure and function in central obese subjects (both normotensives and hypertensives). ET-levels have been assessed by the radioimmunoassay method in 20 lean normote…
Effects of a short-term hypoenergetic diet on morphofunctional left ventricular parameters in centrally obese subjects
2000
BACKGROUND: We aimed to study centrally obese subjects without other diseases, to establish whether a short-term hypoenergetic balanced regimen is able to positively modify left ventricular (LV) patterns. METHODS: We studied 32 obese subjects (out of 52 recruited for this study) with central fat distribution and without associated diseases. Each subject had undergone a moderately hypoenergetic diet for a four-month follow-up period and had a regular loss in weight. Some relevant clinical and echocardiographic parameters were evaluated. Baseline data and those evaluated at the end of the follow-up period were used for outcome analysis. RESULTS: We found a considerable reduction in LV mass an…

FISIOPATOLOGIA DELLA SINTESI DELLE LIPOPROTEINE INTESTINALI
2015
La sintesi di lipoproteine di origine intestinale è un processo sequenziale, necessario per l’assorbimento dei lipidi e delle vitamine liposolubili di origine alimentare. L’assemblaggio dei chilomicroni inizia nel reticolo endoplasmico con la formazione di particelle ricche di fosfolipidi che sono poi trasportate al Golgi per essere secrete. Diverse classi di trasportatori giocano un ruolo sia nell’assorbimento selettivo che nel trasporto di lipidi attraverso i villi intestinali. Una volta secrete nel circolo linfatico, le lipoproteine ricche di trigliceridi (LRT) sono sottoposte all’azione della Lipasi Lipoproteica (LPL), che catalizza l’idrolisi dei triacilgliceroli delle lipoproteine a d…
Micro-albuminuria in obese subjects: relationship among body fat distribution, blood pressure and left ventricular structure and function.
1998
OBJECTIVE: To evaluate the relationships among micro-albuminuria, blood pressure and measurements of left ventricular structure and function in centrally and peripherally obese subjects compared with members of a lean control group. METHODS: Centrally obese subjects were subdivided according to whether they had levels of micro-albuminuria higher than 30 mg/24 h (micro-albuminuric group) or lower than or equal to 30 mg/24 h (normo-albuminuric group). For all the subjects we measured heart rate, casual mean blood pressure (MBP), 24 h MBP, total cholesterol level, high-density lipoprotein cholesterol, lipoprotein (a) level, fasting immunoreactive insulin level, plasma renin activity, plasma al…

Central obesity and hypertension: Pathophysiologic role of renal haemodynamics and function
1995
OBJECTIVE: To investigate the role of alterations in renal haemodynamics and function and in plasma renin activity on obesity-induced hypertension. DESIGN: Renal haemodynamics and function, salt-regulating hormones and structural cardiac parameters were evaluated in 20 lean normotensives and in 64 obese subjects with central or peripheral fat distribution, 43 of them were normotensives and 21 of them were hypertensives. Obesity and central fat distribution were defined according to sex-specific 85th percentile respectively of Body Mass Index (BMI) and Waist to Hip Ratio (WHR). MEASUREMENTS: Serum immunoreactive insulin (IRI), plasma renin activity (PRA), plasma aldosterone (PA), microalbumi…
G.F.R. measuring with 99mTc-DTPA: limits in obstructive acute renal failure.
1991
After a short introduction on the advantages and limits of G.F.R. determination with Ccr, the radioisotopic methods proposed by Schlegel and Gates for this parameter are described, and as well as ERPF and FF, without blood serial samples being necessary. In a severe renal failure case due to obstruction, the Authors have found a great mismatch in the results between the traditional methods and the radioisotopic ones. After the clinical case description, a possible explanation of this discrepancy is proposed: Schlegel and Gates' methods, which well correlate Ccr in chronic renal failure cases, in severe renal failure on obstructive basis, of recent onset, could not indicate the effective glo…
