Differences in cell response could explain higher rates of hypertension in African-Americans

2011-08-31
(Press-News.org) A key difference in the way that cells from African-Americans respond to inflammation could be an answer to why this group is disproportionately affected by hypertension, something that has eluded scientists for many years.

In a study published this month in Vascular Health and Risk Management, lead author Michael Brown and his team tested the effects of TNF-ά, a protein that causes inflammation when cells are damaged, on endothelial cells – which line blood vessels – in both African-Americans and Caucasians, to determine whether the inflammation affected the cells differently.

Among African-American cells, there was a nearly 90 percent increase in the production of endothelial microparticles, small vesicles that are released during inflammation. Individuals with hypertension have been shown to have higher levels of these microparticles in their bloodstream. Among Caucasians, there was only an eight percent increase in their production.

Brown said that although follow-up research needed to be done, "it appears that the endothelial cells in African Americans are more susceptible to the damaging effects of this inflammation." Brown is the director of the Hypertension Molecular and Applied Physiology Laboratory at Temple's College of Health Professions and Social Work.

Brown's research is unique in that it focuses on studying risk of hypertension at the cellular level; most research focuses on the clinical or physiological aspect. For more than 10 years, Brown has been trying to unlock the genetic reason behind the higher rates of hypertension and cardiovascular disease among African Americans.

Brown's research includes an exercise component, to test whether physical activity can reverse or prevent the damage done by hypertension at the cellular level.

"In our human study we have pre-hypertensive African-Americans, and we find this level of endothelial impairment. Knowing so early how inflammation can affect cells means we can be at a place to intervene before they go on to develop hypertension," said Brown. "That intervention could be lifestyle modification, diet and exercise to improve vascular health."

Other authors on this study are Deborah Feairheller, Sunny Thakkar, Praveen Veerabhadrappa and Joon-Young Park of the department of kinesiology. Funding for this study was provided by the National Heart Lung and Blood Institute at the National Institutes of Health.

Scientist creates new hypothesis on ocean acidification

2011-08-31
Since the beginning of the Industrial Revolution, the concentration of carbon dioxide in the atmosphere has been rising due to the burning of fossil fuels. Increased absorption of this carbon by the oceans is lowering the seawater pH (the scale which measures how acidic or basic a substance is) and aragonite saturation state in a process known as ocean acidification. Aragonite is the mineral form of calcium carbonate that is laid down by corals to build their hard skeleton. Researchers wanted to know how the declining saturation state of this important mineral would impact ...

Hurricane Irene: Scientists collect water quality and climate change data from huge storm

Hurricane Irene: Scientists collect water quality and climate change data from huge storm
2011-08-31
While Hurricane Irene had officials along the East Coast preparing for mass evacuations, scientists at the Stroud Water Research Center and the University of Delaware were grabbing their best data collection tools and heading straight for the storm's path. It was a rare opportunity for the scientists to learn more about climate change and water quality, as Irene threatened to be the biggest hurricane to hit the Northeastern United States since 1985. Center scientist Anthony Aufdenkampe explains, "It rains on average once per week, or 15 percent of the year, but streams ...

'French Escapades' Exhibition at the Red Rag Modern Art Gallery, Bath (from Sunday, 18 September 2011)

2011-08-31
There is something unusual, beguiling and quietly engaging about the latest show, French Escapades, at the Red Rag Modern Art Gallery in Bath (which opens on 18 September). It is not that Bath is twinned with a French town (Aix-en-Provence) though that is interesting. Nor is it that it is an exhibition of exceptionally high quality paintings of France by highly skilled contemporary artists, though that might be captivating in itself. It is more its celebration of a timeless journey into memory and reverie that strikes an inner chord - it is a show where it is easy to lose ...
