BACKGROUND The prevalence of cardiovascular mortality is high in Chronic Obstructive Pulmonary Disease (COPD) and the identification of clinical parameters to improve risk stratification is of great interest. OBJECTIVES This study aims to assess the predictive strength of daily walking activity on expression of cardiac biomarkers in patients with COPD. METHODS One hundred and five patients ...

Recently, a new member of the calcitonin gene-related peptide (CGRP) family, adrenomedullin 2 (AM2) or intermedin (IMD), was identified. AM2/IMD has been shown to have a vasodilator effect in mice and rats and an effect on urine formation in rats. In the present study, we investigated the effects of intravenously infused rat AM2 (rAM2) on blood pressure (BP), heart rate (HR), renal sympathetic ...

BACKGROUND Pneumonia is the leading cause of death among infectious diseases in developed countries. However, the severity of pneumonia requiring hospitalization often makes the initial diagnosis difficult because of an equivocal clinical picture or interpretation of the chest film. The objective of the present study was to assess the usefulness of the plasma levels of mid-regional proadrenomed...

Peptides derived from postranslational processing of preproadrenomedullin exert potent hypotensive effects in the periphery. One of those peptides, adrenomedullin (AM) also has been demonstrated to act centrally in conscious rats to inhibit water drinking and salt appetite and, in anesthetized rats, surprisingly to increase blood pressure. We examined the effects of AM and the other postranslat...

Let $nin mathbb{N}$. An additive map $h:Ato B$ between algebras $A$ and $B$ is called $n$-Jordan homomorphism if $h(a^n)=(h(a))^n$ for all $ain A$. We show that every $n$-Jordan homomorphism between commutative Banach algebras is a $n$-ring homomorphism when $n < 8$. For these cases, every involutive $n$-Jordan homomorphism between commutative C-algebras is norm continuous.
