Norwegian University of Science and Technology Norwegian researchers use large database and computer model to understand high blood pressure High blood pressure is highly age-related and affects more than 1 billion people worldwide. But doctors can't fully explain the cause of 90 per cent of all cases. A computer model of a "virtual human" suggests that stiff arteries alone are enough to cause high blood pressure. "Our results suggest that arterial stiffness represents a major...

Institute of Physics An implantable device that reduces blood pressure by sending electrical signals to the brain has been created by a group of researchers in Germany. The device has successfully reduced the blood pressure in rats by 40 per cent without any major side effects, and could offer hope for a significant proportion of patients worldwide who do not respond to existing medical treatment for the condition. The first results have been published today, 9 May, in IOP...

The study, led by an OHSU School of Dentistry researcher, is the first to link blood pressure with levels of a molecule known as BDNF, or Brain-Derived Neurotrophic Factor Researchers at Oregon Health & Science University's School of Dentistry have made an important connection between a molecule critical to nerve cells and high blood pressure. Production of the molecule Brain-Derived Neurotrophic Factor (BDNF) appears to increase dramatically in blood pressure-sensing nerve cells...

The research, published in the Journal of Neuroscience Research, sheds light on what determines availability of the molecules involved in blood pressure control Researchers at Oregon Health & Science University's School of Dentistry have discovered that nitric oxide is a powerful regulator of a molecule that plays a critical role in the development and function of the nervous system. The finding could someday play a significant role in the prevention and treatment of high blood pressure,...

University of Iowa researchers have shown that a protein channel helps nerve sensors in blood vessels keep blood pressure in check. Without the protein channel, known as ASIC2, the sensors are unable to send the brain the signals it needs to properly control blood pressure. The finding, which was based in animal models, is important because it could be used to create new treatments to prevent high blood pressure (hypertension). The study results appear in the Dec. 24 print issue of the...

Two U.S. medical device companies are trying to bring back the use of some old blood pressure treatments, updated with high-tech gadgetry. Two small studies presented Monday at a meeting of the American College of Cardiology suggest severing nerves or zapping neck arteries can substantially decrease blood pressure, the Wall Street Journal reported. Those type of procedures were used more 50 years ago but were largely discontinued because of the risk of major complications, the newspaper...

Huijing Xia, PhD, a postdoctoral research associate in the lab of Eric Lazartigues, PhD, Assistant Professor of Pharmacology at LSU Health Sciences Center New Orleans, is the lead author on a paper reporting that a recently identified enzyme in the brain plays a critically important role in the central regulation of blood pressure. The LSUHSC research team showed that Angiotensin-converting enzyme 2 (ACE2) helps preserve the function of a key spontaneous reflex involved in blood pressure...

Researchers at Oregon Health & Science University's School of Dentistry (www.ohsu.edu/sod) have discovered that the nerve cells controlling heart rate and blood pressure synthesize a molecule known to be critically important for proper nervous system growth. The finding could someday play a significant role in the prevention of Sudden Infant Death Syndrome (SIDS) and high blood pressure. According to the National Institutes of Health, SIDS is the leading cause of death in children between...


Word of the Day
endocarp
  • The hard inner (usually woody) layer of the pericarp of some fruits (as peaches or plums or cherries or olives) that contains the seed.
This word comes from the Greek 'endon,' in, within, plus the Greek 'kardia,' heart.
