Adaptations to iron deficiency: cardiac functional responsiveness to norepinephrine, arterial remodeling, and the effect of beta-blockade on cardiac hypertrophy. [PDF]

open access: yes, 2002
BackgroundIron deficiency (ID) results in ventricular hypertrophy, believed to involve sympathetic stimulation. We hypothesized that with ID 1) intravenous norepinephrine would alter heart rate (HR) and contractility, 2) abdominal aorta would be larger ...

The role of inhibitory G proteins and regulators of G protein signaling in the in vivo control of heart rate and predisposition to cardiac arrhythmias [PDF]

open access: yes, 2012
Inhibitory heterotrimeric G proteins and the control of heart rate. The activation of cell signaling pathways involving inhibitory heterotrimeric G proteins acts to slow the heart rate via modulation of ion channels.

Role for inflammatory markers in predicting right ventricular failure in mechanical assist device recipients

open access: yesESC Heart Failure, EarlyView.
Abstract Right ventricular failure (RVF) is a common complication following left ventricular assist device (LVAD) implantation and increases patient morbidity and mortality. Due to the complex and limited understanding of RVF pathophysiology, efforts to prognosticate RVF after LVAD have been challenging.

Labor-associated gene expression in the human uterine fundus, lower segment, and cervix [PDF]

open access: yes, 2006
Background Preterm labor, failure to progress, and postpartum hemorrhage are the common causes of maternal and neonatal mortality or morbidity. All result from defects in the complex mechanisms controlling labor, which coordinate changes in the ...

Mortality risk stratification for Takotsubo syndrome: Evaluating CRP measurement alongside the InterTAK prognostic score

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 1427-1436, April 2025.
Abstract Background and objectives Initially described as a benign acute cardiomyopathy, Takotsubo syndrome has been linked to elevated mortality rates. Emerging evidence suggests that unresolved myocardial inflammation may contribute to this adverse prognosis.

An Oral Selective Alpha-1A Adrenergic Receptor Agonist Prevents Doxorubicin Cardiotoxicity

open access: yesJACC: Basic to Translational Science, 2017
Summary: Alpha-1 adrenergic receptors (α1-ARs) play adaptive and protective roles in the heart. Dabuzalgron is an oral selective α1A-AR agonist that was well tolerated in multiple clinical trials of treatment for urinary incontinence, but has never ...

Current and novel biomarkers in cardiogenic shock

open access: yesEuropean Journal of Heart Failure, EarlyView.
A summary of current and novel biomarkers and their potential stages of release in cardiogenic shock. The diagram illustrates the proposed release of the biomarkers during the different stages of cardiogenic shock: progression from cardiac dysfunction/stress, through to inflammation and end‐organ dysfunction.

Exploring the Potential of Liposomal Delivery of Naringenin and Berberine for Browning Adipose Tissue and Obesity Management

open access: yesEuropean Journal of Lipid Science and Technology, EarlyView.
Biocompatible and biodegradable liposomes were developed to encapsulate naringenin (N) and berberine (B), enhancing their stability and bioavailability. Their effects on thermogenesis and browning in 3T3‐L1 preadipocyte cells compared to their free forms were investigated.

The Effect of a Reduced-Calorie Diet on alpha-2 Adrenergic Receptor Responsiveness in Abdominal Adipose Tissue in Obese Men During Exercise [PDF]

open access: yes, 2008
There is at present an imperfect understanding of the effect of diet on availability of inhibitory receptors in fat cells during exercise among obese men. *Objective:* The purpose of this study was to determine whether diet results in
