Protein kinase A activated in the nucleus as well as the cytoplasm

Using a new tool allowing proteins in a living cell to be manipulated in real time, researchers at Johns Hopkins have stumbled across the answer to a longstanding debate about where and how a certain protein is turned on in the cell. Reporting in the February 2012 issue of Nature Chemical Biology, scientists show that protein kinase A is also activated in the nucleus rather than inside the cell’s body, a challenge to traditional beliefs.

Registry proves invaluable for fibromuscular dysplasia patients

A patient registry is proving invaluable in cataloging the clinical features, symptoms, severity, and outcomes of fibromuscular dysplasia (FMD), a non-inflammatory vascular disease that can cause narrowing of arteries in the carotid (neck) and renal (kidney) arteries, which can result in headache, strokes, and aneurysms.

Magnet guides iron-loaded cells to specific damaged sites in the heart

Optimal stem cell therapy delivery to damaged areas of the heart after myocardial infarction has been hampered by inefficient homing of cells to the damaged site. However, using rat models, researchers in France have used a magnet to guide cells loaded with iron oxide nanoparticles to key sites, enhancing the myocardial retention of intravascularly delivered endothelial progenitor cells.

Women & Infants Hospital of Rhode Island to participate in Best Fed Beginnings

Women & Infants Hospital of Rhode Island has been selected to participate in Best Fed Beginnings, a first-of-its-kind national effort to significantly improve breastfeeding rates in states where rates are currently the lowest. Rhode Island ranks 35th in the nation for breastfeeding initiation. Women & Infants is the only hospital in New England to be selected for this collaborative.

Broken heart syndrome may protect the heart from adrenaline overload

A condition that temporarily causes heart failure in people who experience severe stress might actually protect the heart from very high levels of adrenaline, according to a new study published in the journal Circulation. The research provides the first physiological explanation for Takotsubo cardiomyopathy, also called "broken heart syndrome" because it affects people who suffer severe emotional stress after bereavement, and suggests guidance for treatment.

OOM women in mid-pregnancy have reduced levels of EDCs than general population

A lifestyle that features fresh foods and limited use of products likely to contain environmental chemicals has been shown to reduce exposure to endocrine-disrupting chemicals (EDCs), such as BPA and phthalates, in a small population study. EDCs are linked to a number of adverse health complications including neuro-developmental delays, behavioral issues and fertility problems.

Study: Moderate coffee intake reduces risk of heart failure

While current American Heart Association heart failure prevention guidelines warn against habitual coffee consumption, some studies propose a protective benefit, and still others find no association at all. Amidst this conflicting information, research from Beth Israel Deaconess Medical Center attempts to shift the conversation from a definitive yes or no, to a question of how much.

Maternal factors associated with fetal growth restriction

A Japanese study has found that maternal rather than fetal factors are associated with fetal growth restriction. A comparison of maternal and fetal angiotensin-converting enzyme genotypes with the size of babies at birth found evidence of this connection.
