The Internet of Things (IoT) is a technological topic with a very important societal impact. IoT application domains are various, such as smart cities, precision farming, smart factories, smart buildings, etc, and the diversity of these application domains is the source of the very high technological heterogeneity in the IoT, leading to interoperability issues. The semantic web principles and t...

Background. Atrial natriuretic peptide (ANP) is a hormonal regulator of cardiovascular fluid volume. More than 1,000 scientific articles were written about ANP between 1987 and 1991. Because some articles hinted at problems with storing ANP, this study examined the effect of numerous techniques for storing and processing human ANP samples. Methods and Results. Samples were obtained repeatedly f...

The feedback control of neuroendocrine activity by cardiopulmonary blood volume is disturbed in congestive heart failure. By analyzing plasma catecholamine kinetics, we tested in 11 chronically instrumented conscious dogs whether attenuations in the sympathoadrenal inhibition induced by atrial natriuretic peptide (ANP) contributed to this disturbance. Low-output failure was brought about by con...

Glomerular hyperfiltration in streptozotocin-induced diabetes mellitus in rats may be mediated by atrial natriuretic peptide (ANP). We wanted to evaluate plasma levels of ANP and plasma volume in relation to renal ANP receptor density and affinity in rats 6 weeks after induction of diabetes. Plasma levels of immunoreactive ANP were significantly higher in hyperglycemic diabetic (75.2 +/- 8.3 pg...

BACKGROUND Plasma levels of atrial natriuretic peptide (ANP) are elevated in patients with chronic obstructive pulmonary disease (COPD) and may have a role in preventing oedema formation in these patients. METHODS Plasma ANP levels were measured in 60 patients with COPD and these measurements were related to pulmonary haemodynamics, response to treatment during exacerbations, and clinical pat...

Introduction: Ethyl pyruvate (EP), a natural flavoring and fragrance agent, has been shown to exert anti-inflammatory and antioxidant actions. We tested the potential beneficial effects of EP in a rat model of acute necrotizing pancreatitis (ANP), a serious condition with a significant inflammatory explosion and oxidative stress. Material and methods: Fifty-two adult male Sprague-Dawley rats we...

AIMS Atrial natriuretic peptide (ANP) is well known to modulate fluid and electrolyte homeostasis but also to counter-regulate hypothalamic-pituitary-adrenal (HPA) axis activity. Correspondingly, recent studies suggest an important role of ANP in the neurobiology of anxiety. Preclinical and clinical data now provide evidence for an involvement of ANP in the pathophysiology of addictive behavior...

Studies done in vitro have demonstrated that atrial natriuretic peptide (ANP) antagonizes angiotensin II-mediated contraction of vascular smooth muscle. The present studies were designed to examine the in vivo actions of ANP in acute angiotensin II-mediated hypertension. The cardiovascular, renal, and hormonal effects of intravenous ANP were evaluated in anesthetized normotensive (n = 6) and hy...

To investigate the ventricular expression of atrial natriuretic peptide (ANP) in human hypertrophic hearts, we conducted an immunohistochemical study of 130 endomyocardial biopsy specimens obtained from the right side of the ventricular septum (RVB), left ventricular free wall (LVB), or both from a total of 80 patients: 44 patients with hypertrophic cardiomyopathy (HCM), 14 with apical hypertro...
