1. Difficulties in maintaining potassium homeostasis in patients with heart failure.
Match Strength: 7.016

Potassium (K) concentration plays a significant role in cell metabolism and membrane excitability. The imbalance of serum potassium is important because it can lead to life-threatening events. Potassium balance may be lost both through the neurohormonal mechanisms involved in cardiovascular diseases and through the drugs used in the treatment of this illness. Avoiding both hypo- and hyperkalemia is beneficial in several cardiovascular diseases, especially heart failure. Electrolyte abnormalities are frequently seen complications in subjects with heart failure. Malignant ventricular arrhythmias ... Read More »

3. S-nitrosylation: NO-related redox signaling to protect against oxidative stress.
Match Strength: 5.649

Nitric oxide (NO) plays an important role in the regulation of cardiovascular function. S-nitrosylation, the covalent attachment of an NO moiety to sulfhydryl residues of proteins, resulting in the formation of S-nitrosothiols (SNOs), is a prevalent posttranslational protein modification involved in redox-based cellular signaling. Under physiologic conditions, protein S-nitrosylation and SNOs provide protection preventing further cellular oxidative and nitrosative stress. However, oxidative stress and the resultant dysfunction of NO signaling have been implicated in the pathogenesis of ... Read More »

5. NADPH oxidases of the brain: distribution, regulation, and function.
Match Strength: 4.800

The NADPH oxidase is a multi-subunit enzyme that catalyzes the reduction of molecular oxygen to form superoxide (O(2)(-)). While classically linked to the respiratory burst in neutrophils, recent evidence now shows that O(2)(-) (and associated reactive oxygen species, ROS) generated by NADPH oxidase in nonphagocytic cells serves myriad functions in health and disease. An entire new family of NADPH Oxidase (Nox) homologues has emerged, which vary widely in cell and tissue distribution, as well as in function and regulation. A major concept in redox signaling is that while NADPH oxidase-derived ... Read More »

7. Capillary microscopy and hemorheology in children during antiepileptic monotherapy with carbamazepine and valproate.
Match Strength: 4.435

The interactions of epilepsy and antiepileptic therapy an one hand and cardiovascular system on the other hand are multiple and complex. Antiepileptic drugs (AEDs) cause alterations of serum lipids and of the fatty acid composition of the membranes. Homocystein, known to induce vascular endothelial damage was found to be elevated in patients on valproate (VPA) and carbamazepine (CBZ) therapy. Marked coronary artherosclerosis and myocardial infarction may already occur in children treated with CBZ. Community based studies corroborated a higher incidence of myocardial infarction, peripheral ... Read More »

10. Drug insight: statins and gastrointestinal cancer.
Match Strength: 3.842

Statins are popular lipid-lowering drugs that have had a great impact on the primary and secondary prevention of cardiovascular diseases. Basic and clinical research have also revealed that statins have biologic activities that go beyond lipid lowering, and suggest that they might have other therapeutic benefits. Perhaps the most exciting of these additional biologic effects is the finding that statins can exert an anticancer effect on cultured cancer cells, and in animal models. Clinical studies of statins for the treatment and prevention of cancer have, however, produced conflicting results. ... Read More »

11. Mutations of TGFbeta signaling molecules in human disease.
Match Strength: 3.656

The transforming growth factor beta (TGFbeta) signaling pathway regulates several biological processes including cellular proliferation, differentiation, apoptosis, migration, and extracellular matrix deposition. Ligand and receptor family members signal through two main Smad signaling branches, TGFbeta/activin to Smad2/3 (Sma and MAD-related proteins) and bone morphogenetic protein (BMP) to Smad1/5. At the molecular level, TGFbeta acts by modifying cytoskeletal organization and ultimately regulating expression of specific target genes. Germline disruption of TGFbeta signaling leads to several ... Read More »

12. Antioxidant and antiaggregatory effects of an extract from Conyza canadensis on blood platelets in vitro.
Match Strength: 3.641

The antioxidative activity of the polysaccharide extract from Conyza canadensis in blood platelets treated with peroxynitrite (ONOO-) was studied. Peroxynitrite as a strong biological oxidant has toxic effects on blood platelets and induces the oxidation of thiols, carbonylation and nitration of platelet proteins and lipid peroxidation. Therefore, the aim of our study was to assess if the natural extract from herbal plant, Conyza Canadensis, may protect platelet proteins against nitrative and oxidative damage induced by ONOO-. In our study we measured oxidative damage of platelet proteins ... Read More »

13. Cardiac imaging in rheumatic diseases.
Match Strength: 3.599

The majority of the imaging techniques in cardiology could be applied in rheumatic diseases (RDs), such as echocardiography, single-photon emission computed tomography (SPECT), radionuclide ventriculography, angiography, cardiovascular MRI and CT. Inflammatory pericardial involvement is the most common cardiac manifestation in various forms of RD. Echocardiography is the gold standard for diagnosis of pericardial abnormalities, demonstrating location and amount of pericardial effusion. Cardiac MRI and CT can be used to assess the features of pericardial effusions and peracardial structures. In ... Read More »

14. Plasma glycoprotein V levels in the general population: normal distribution, associated parameters and implications for clinical studies.
Match Strength: 3.584

Soluble glycoprotein V (sGPV) is a new plasma marker of thrombosis released from the platelet surface by thrombin. sGPV levels are increased in patients with atherothrombotic diseases, but the determinants of sGPV levels are unknown in the general population. Identification of these potential confounding factors is needed for correct design and analysis of clinical studies on cardiovascular diseases. The aim of this study was to determine the normal range of plasma values and the factors controlling sGPV levels in a population of normal individuals. Three hundred blood donors were recruited at ... Read More »

15. Redefining oxidative stress.
Match Strength: 3.104

Oxidative stress is often defined as an imbalance of pro-oxidants and antioxidants, which can be quantified in humans as the redox state of plasma GSH/GSSG. Plasma GSH redox in humans becomes oxidized with age, in response to oxidative stress (chemotherapy, smoking), and in common diseases (type 2 diabetes, cardiovascular disease). However, data also show that redox of plasma GSH/GSSG is not equilibrated with the larger plasma cysteine/cystine (Cys/CySS) pool, indicating that the "balance" of pro-oxidants and antioxidants cannot be defined by a single entity. The major cellular thiol/disulfide ... Read More »

18. Free radicals and antioxidants in normal physiological functions and human disease.
Match Strength: 2.932

Reactive oxygen species (ROS) and reactive nitrogen species (RNS, e.g. nitric oxide, NO(*)) are well recognised for playing a dual role as both deleterious and beneficial species. ROS and RNS are normally generated by tightly regulated enzymes, such as NO synthase (NOS) and NAD(P)H oxidase isoforms, respectively. Overproduction of ROS (arising either from mitochondrial electron-transport chain or excessive stimulation of NAD(P)H) results in oxidative stress, a deleterious process that can be an important mediator of damage to cell structures, including lipids and membranes, proteins, and DNA. ... Read More »

19. Nonparametric estimation of stage occupation probabilities in a multistage model with current status data.
Match Strength: 2.916

Multistage models are used to describe individuals (or experimental units) moving through a succession of "stages" corresponding to distinct states (e.g., healthy, diseased, diseased with complications, dead). The resulting data can be considered to be a form of multivariate survival data containing information about the transition times and the stages occupied. Traditional survival analysis is the simplest example of a multistage model, where individuals begin in an initial stage (say, alive) and move irreversibly to a second stage (death). In this article, we consider general multistage ... Read More »
