Value of Home Blood Pressures as Predictor of Target Organ Damage in Mild Arterial Hypertension

2002

Home blood pressure measurement has gained increasing importance for the management of hypertensive patients. The aim of our study was to compare levels of clinic (CBP), ambulatory (ABP), and home blood pressure (HBP) measurements, and their relationships with various indexes of target organ damage in I-II grade essential hypertension.Thirty-eight essential hypertensives underwent evaluation of clinic, ambulatory and home blood pressures. Each patient recorded HBP for 2 days with a digital BP monitor three times daily, the first time on the same day during which ABP monitoring was simultaneously performed. Moreover, in all subjects electrocardiogram recording, echocardiographic study, micro…

Insulin resistance and endogenous digoxin-like factor in obese hypertensive patients with glucose intolerance

1992

Hypertensive obese subjects with glucose intolerance have hyperinsulinaemia, insulin resistance and intracellular cation imbalance resulting in increased sodium content. The aim of our study was to assess in these patients plasma levels of endogenous digoxin-like factor (EDLF), an inhibitor of the sodium-pump mechanism. We studied 14 hypertensive and 12 normotensive subjects with obesity and glucose intolerance for fasting blood glucose, and plasma insulin, C-peptide and EDLF levels: the two groups were matched for age and BMI and were studied after a 2-week wash-out period from hypotensive drugs. Compared with normotensives, hypertensive subjects had higher plasma insulin levels, a greater…

Relationships between 24 h blood pressure load and target organ damage in patients with mild-to-moderate essential hypertension.

2001

Objective: To analyse the relationships between 24 h blood pressure load (the percentage of systolic/diastolic blood pressures exceeding 140/90 mmHg while awake and 120/80 mmHg during sleep) and some indices of hypertensive target organ involvement, independently of the mean level of 24 h blood pressure. Methods: One hundred and thirty patients with mild-to-moderate hypertension underwent 24 h ambulatory blood pressure monitoring, ocular fundus examination, microalbuminuria assay and two-dimensional guided M-mode echocardiography. The study population was divided into subsets according to the systolic and diastolic 24 h blood pressure load values predicted from the regression equation relat…

Yield and Quality of Mini-Watermelon as Affected by Grafting and Mycorrhizal Inoculum

2016

Grafting and mycorrhizal fungi have gained interest for the positive effects they can have on vegetable crops. The aim of this work was to study the combined effect of grafting with Vesicular-Arbuscular Mycorrhizal fungi (AMF) inoculation on fruit yield and quality of mini-watermelon [Citrullus lanatus (thumb.) Matsum and Nakai]. Ungrafted plants or grafted onto rootstock RS 841 F1 (Cucurbita maxima × C. moschata) were transplanted to the field. During cultivation half of the plants were inoculated with a suspension of AMF. Plant growth, fruit yield and quality were evaluated. The inoculation of AMF determined a significant increase of root colonisation both for grafted and ungrafted plants…

Insulin-like growth factor 1 and sodium-lithium countertransport in essential hypertension and in hypertensive left ventricular hypertrophy

1993

The aim of this work was to study the insulin-like growth factor 1 (IGF1), a substance able to promote cell proliferation in vascular smooth muscle, in patients with mild-to-moderate hypertension and to analyse its relationship to sodium-lithium countertransport, a genetic marker of hypertension that is related to cardiovascular complications.We studied 32 hypertensive subjects, some with left ventricular hypertrophy, and 14 healthy subjects. Fasting plasma IGF1 was measured by means of a radioimmunoassay after octadecylsilica chromatography and Na(+)-Li+ countertransport was determined by the method of Canessa.Hypertensive patients had higher values of both IGF1 and Na(+)-Li+ countertransp…

Influence of the metabolic syndrome on aortic stiffness in never treated hypertensive patients

Summary Background and aim Metabolic syndrome (MS) carries an increased risk for cardiovascular events and there is a growing awareness that large artery stiffening is a powerful predictor of cardiovascular morbidity and mortality. Little is known about the relationship of MS with aortic stiffness. The aim of our study was to analyze, in patients with essential hypertension, the influence of MS, defined according to the criteria proposed by the Third Report of the National Cholesterol Education Program Expert Panel on Detection, Evaluation, and Treatment of High Blood Cholesterol in Adults (NCEP-ATP III), on carotid–femoral pulse wave velocity (PWV), a measure of aortic stiffness.

In the overall study population, both the BPcomponents showed significant correlations with LVM.These correlations were unevenly distributed in thesubgroups of subjects younger and in those older than50 years. While in this latter subgroup, in multivariateanalysis, both 24-h mean BP (24-MBP) (b¼0.27;P¼0.008) and 24-h pulse pressure (24-h PP) (b¼0.23;P¼0.02) were associated with LVM, in th…

Endothelium-derived factors in microalbuminuric and nonmicroalbuminuric essential hypertensives

2000

Previous evidence has demonstrated a relationship between growth factors and cardiovascular diseases. This study was aimed at evaluating levels of some endothelium-derived growth factors, and their relationship with microalbuminuria (MAU), in essential hypertension. Ninety-nine mild-moderate essential hypertensives (EH) and 25 healthy controls were studied. All patients underwent 24-h blood pressure monitoring, serum endothelin-1 (ET-1), basic fibroblast growth factor (bFGF) and platelet-derived growth factor (PDGF), and 24-h MAU assays. Later, EH were divided into two subsets consisting of microalbuminurics (MAU >11 microg/min) and nonmicroalbuminurics (MAU <11 microg/min). In microalbumin…

Modelling of the thermal mechanical behaviour of a single size beryllium pebble bed

2001

The Helium Cooled Pebble Bed (HCPB) Blanket for fusion power reactors and the ITER breeding blanket are based on the use of pebble beds of lithium ceramics as breeder and beryllium as neutron multiplier. Experimental activities were performed at Forschungszentrum Karlsruhe concerning the measurement of pebble bed heat transfer parameters. At the Department of Nuclear Engineering of the University of Palermo, the experimental results have been reproduced by means of the ABAQUS finite element code. Moreover, a thermal-mechanical theoretical model has been developed for single size beryllium pebble beds. In the paper the results from the numerical and theoretical analyses and the comparison wi…

Relationships between ambulatory white coat effect and left ventricular mass in arterial hypertension

2003

The aim of our study was to analyze, in a group of 296 essential hypertensives, the relationship between left ventricular mass (LVM) and ambulatory white coat effect (WCE); that is the difference between the elevation of the first measurements of ambulatory blood pressure monitoring and the mean daytime pressure. The study population was separated into two groups according to the median of the WCE. The LVM was greater in the groups with higher systolic and diastolic ambulatory WCE. The significant association between ambulatory WCE and LVM was confirmed by the results of multiple regression analysis, suggesting that ambulatory WCE may not be an innocent phenomenon.

Botryosphaeriaceae species associated with diseased loquat trees in Italy and description of Diplodia rosacearum sp. nov

2016

[EN] Loquat (Eriobotrya japonica) is a fruit tree cultivated in several countries in the Mediterranean region. A survey of a loquat orchard in Sicily ( Italy) revealed the presence of plants showing dieback symptoms and cankers with wedge-shaped necrotic sectors. Fungi from the genera Diplodia and Neofusicoccum were isolated from symptomatic plants. On the basis of morphological characters and DNA sequence data four species were identified, Neofusicoccum parvum, N. vitifusiforme, Diplodia seriata and a novel Diplodia species, which is here described as D. rosacearum sp. nov. Inoculation trials of loquat plants cv Sanfilipparo showed that N. parvum, D. seriata and D. rosacearum were pathogen…
