1. The role of estrogens in cardiovascular disease in the aftermath of clinical trials.
Match Strength: 5.326
The effects of estrogens on reproductive tissues and climacteric symptoms are unambiguous. However, their effects on other tissues and, in particular, the cardiovascular system remain controversial. In general, premenopausal women are protected from coronary heart disease (CHD) compared with aged-matched men but this ;female protection' appears to be lost after menopause, suggesting beneficial effects of female sex hormones on the cardiovascular system. This view has been supported by observational studies showing that estrogen replacement therapy (ERT) is associated with a 30% to 50% decrease ... Read More »

2. Efficacy and safety of tamsulosin OCAS.
Match Strength: 4.957
The efficacy and safety of a new tablet formulation of tamsulosin (the oral-controlled absorption system: OCAS(R)) have been assessed in several clinical trials. In a phase IIb and a phase IIIa trial, the appropriate dose of the tamsulosin tablet for clinical practice was determined. All tested doses of tamsulosin OCAS (0.4, 0.8 and 1.2 mg) improved the lower urinary symptoms (LUTS) of benign prostatic enlargement to a statistically significantly greater extent than placebo, with no differences between the doses. However, treatment with tamsulosin OCAS 0.4 mg was associated with a lower ... Read More »

3. Gadolinium does not blunt the cardiovascular responses at the onset of voluntary static exercise in cats: a predominant role of central command.
Match Strength: 4.765
The cardiovascular adaptation at the onset of voluntary static exercise is controlled by the autonomic nervous system. Two neural mechanisms are responsible for the cardiovascular adaptation: one is central command descending from higher brain centers, and the other is a muscle mechanosensitive reflex from activation of mechanoreceptors in the contracting muscles. To examine which mechanism played a major role in producing the initial cardiovascular adaptation during static exercise, we studied the effect of intravenous administration of gadolinium (55 micromol/kg), a blocker of stretch ...

4. Cardiovascular actions of adrenocorticotropin microinjections into the nucleus tractus solitarius of the rat.
Match Strength: 4.359
The presence of adrenocorticotropin (ACTH) containing cells and melanocortin (MC) receptors has been reported in the nucleus tractus solitarius (NTS) of the rat. The importance of the NTS in the regulation of cardiovascular function is also well established. Based on these reports, it was hypothesized that ACTH acting within the NTS may modulate the central regulation of cardiovascular function. To test this hypothesis, cardiovascular effects of ACTH in the NTS were investigated in intact urethane-anesthetized and unanesthetized decerebrate, artificially ventilated, adult male Wistar rats. ...

5. NADPH oxidases of the brain: distribution, regulation, and function.
Match Strength: 4.293
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 »

6. Gastrointestinal-related complications after major lung surgery.
Match Strength: 3.612
Numerous factors increase the risk for GI complications in patients undergoing lung resection. It seems that the more debilitated the patient and the more extensive the COPD, the higher the risk. The most commonly reported cause of mortality after lung surgery is multi-organ failure accompanying respiratory failure. The trigger site for multi-system failure is often the GI system. Some risk factors cannot be altered, such as diabetes and the cardiovascular effects of long-term smoking. Other factors, such as steroid dose, anemia, hypoxia, narcotics, and other medications, can be modified. In ... Read More »

7. Treatment of poisoning caused by beta-adrenergic and calcium-channel blockers.
Match Strength: 3.591
PURPOSE: The toxic effects and treatment of beta-adrenergic blocker and calcium-channel blocker (CCB) overdose are reviewed. SUMMARY: Overdoses with cardiovascular drugs are associated with significant morbidity and mortality. Beta-blockers and CCBs represent the most important classes of cardiovascular drugs. In overdose, beta-blockers and CCBs have similar presentation and treatment overlaps and are often refractory to standard resuscitation measures. The common feature of beta-blocker toxicity is excessive blockade of the beta-receptors resulting in bradycardia and hypotension. Poisoning by ... Read More »

9. Vascular dysfunction in S1P2 sphingosine 1-phosphate receptor knockout mice.
Match Strength: 3.561
There is growing evidence that sphingosine 1-phosphate (S1P) plays an important role in regulating the development, morphology, and function of the cardiovascular system. There is little data, however, regarding the relative contribution of endogenous S1P and its cognate receptors (referred to as S1P(1-5)) to cardiovascular homeostasis. We used S1P(2) receptor knockout mice (S1P(2)(-/-)) to evaluate the role of S1P(2) in heart and vascular function. There were no significant differences in blood pressure between wild-type and S1P(2)(-/-) mice, measured in awake mice. Cardiac function, ... Read More »

10. Hesr1 knockout mice exhibit behavioral alterations through the dopaminergic nervous system.
Match Strength: 3.491
The basic helix-loop-helix (bHLH) transcriptional factor Hesr1 gene (hairy and enhancer of split-related 1, also called Hey1/HRT1/CHF2/HERP2) has been identified and characterized as a member of the subfamily of hairy/Enhancer of split, and shown to be involved in cardiovascular and neural development. We report that HESR1 binds directly to a part of the 3' non-coding region of the human dopamine transporter (DAT1) gene and represses the endogenous DAT1 gene in HEK293 cells. To investigate functions of the HESR1 gene in the dopaminergic nervous system in vivo, we analyzed the expressions of ... Read More »

12. Circulating activities of angiotensin-converting enzyme, its homolog, angiotensin-converting enzyme 2, and neprilysin in a family study.
Match Strength: 3.272
The renin-angiotensin system is a key regulator of blood pressure (BP), with inhibitors of angiotensin-converting enzyme (ACE) used clinically to treat hypertension and other cardiovascular conditions. ACE2 is a newly identified member of this system, which converts angiotensin II to angiotensin, and of which the occurrence in plasma has not been investigated. The aim of this study was to determine the heritability of circulating ACE, ACE2, and neprilysin (NEP), which may also be a regulator of BP, in a family study, and to determine covariates that contribute to the variation in plasma ...

13. Obstructive sleep apnoea syndrome and genes.
Match Strength: 3.230
Obstructive sleep apnoea (OSA) is a complex disease entity strongly influenced by genetic factors, especially those that affect obesity and fat distribution, upper airway muscle tone, craniofacial morphology, ventilatory control and sleep, giving rise to the OSA phenotype. OSA can also be considered a metabolic syndrome which adversely affects multiple organ systems, especially the cardiovascular system and the brain. The most widely used clinical marker for the diagnosis of OSA is the apnoea-hypopnoea index, calculated by polysomnography. A percentage of 35 to 40% of its variance can be ... Read More »

15. Capillary microscopy and hemorheology in children during antiepileptic monotherapy with carbamazepine and valproate.
Match Strength: 3.166
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 »
