Researchers at the University of Pennsylvania School of Medicine have modified honeybee venom so that it can be used as a tool to study the inner workings of ion channels that control heart rate and the recycling of salt in kidneys. In general, ion channels selectively allow the passage of small ions such as sodium, potassium, or calcium into and out of the cell.

High blood pressure is a time bomb that can trigger a deadly heart attack or stroke without warning. And because the condition often has no symptoms, getting checked is the only way to know whether you have it and if it is under control. To make checking your blood pressure easier and more accessible, the Health Department is teaming up with pharmacies in East and Central Harlem, the South Bronx, and North and Central Brooklyn to provide blood pressure monitoring machines at no cost.
Working up a sweat could be the most important lifestyle change people with high blood pressure — or hypertension — can make in their daily lives. Yet, although patients who receive exercise counseling seem to listen, few physicians actually take the time to talk about physical activity with their patients, a large nationwide study finds.
Just over one-third of people with a hypertension diagnosis said a clinician told them to increase their physical activity to help lower their blood pressure.
The American Heart Association now recommends 24-hour blood pressure monitoring for certain children and adolescents suspected of having high blood pressure or a condition that causes unreliable readings at the doctor’s office.
The statement, published in Hypertension: Journal of the American Heart Association, is expert-opinion driven and not evidence-based. That’s because studies relating 24-hour monitoring in children to hard outcomes like heart attack and stroke are not yet available.
The air people breathe while walking in the park, working in the garden or shopping downtown may be unhealthy enough to seriously spike their blood pressure, a new study suggests.
Cardiovascular researchers at The Ohio State University Medical Center are the first to report a direct link between air pollution and its impact on high blood pressure, or hypertension. If the results from these animal studies hold up, this could be important for human health.
Healthy individuals with higher levels of albumin excretion, even levels considered normal, are at increased risk of developing hypertension (high blood pressure).
Because kidneys normally prevent large molecules such as albumin from being excreted in the urine, high levels of urinary albumin excretion— called albuminuria—can be an indicator of kidney damage. Albuminuria may also reflect dysfunction of endothelial cells throughout the body, which in turn may be a precursor to hypertension.
A new study suggests that American men are much more likely than women are to be unaware that they suffer from high blood pressure. African-American men with the condition are at the highest risk, with only one in seven both aware of their illness and able to control it through medication.
Many of the 75 million Americans with essential hypertension also develop diabetes and other complications in addition to their high blood pressure, and researchers have discovered a common molecular mechanism in a strain of rat that explains why such metabolic disorders arise together in mammals.
InterCure announced the findings of new studies and analysis highlighting RESPeRATE -- the only medical device cleared by the FDA and CE-approved for the treatment of hypertension. Five posters will be presented at the European Society of Hypertension meeting (ESH) in Berlin beginning June 14, 2008. Two of the five posters focus on RESPeRATE's effect on blood pressure as measured by 24-hour ambulatory blood pressure monitoring. Three of the posters also present new findings in the emerging field of obtaining vascular risk parameters from blood pressure measurements.
