Nitric oxide NO) plays a variety of complex roles in the genesis, growth and death of cancer cells/tumors. As it does in so many physiological processes, it exhibits both pro- and anti-tumor activities, and researchers are still discussing the implications of these data on the use of NO as a therapeutic agent for the treatment of cancer. … Continue reading New microneedle biosensor detects nitric oxide during cancer diagnosis→
News about blueberries. A small study—48 post-menopausal women who were pre- or stage 1 hypertensive—showed that participants who took 22 grams (that’s .77 of an ounce for those of us who are gram-challenged) of freeze-dried blueberry powder (equivalent to one cup of the fresh fruit) every day for a month lowered their blood pressure and limbered … Continue reading Blueberries lower BP and raise nitric oxide levels→
#158935349 / gettyimages.com Well, I’m glad to read about this recent study saying sun exposure may play a role in preventing obesity and diabetes. They used mice, and those little guys are covered with fur and don’t spend a lot of time in the sun. But in many ways their bodies operate a lot like … Continue reading Sun exposure = nitric oxide = lower risk of obesity/diabetes→
Doctors have discovered that one of the medicines routinely given to end-stage heart failure patients to block the kidneys from retaining water may also be blocking reception of vital signals that tell the heart to beat more strongly. A catch-22 they can now begin to study and hopefully remedy soon. Mesenchymal stem cells are being used … Continue reading Heart failure, stem cell & nitric oxide news bytes→
If you’ve read even a few of the posts on BioMedNews.org, you probably know I love writing about research that involves nitric oxide (NO). I was introduced to the power of NO about ten years ago when I wrote a white paper on asthma research for the Lerner Research Institute at the Cleveland Clinic. In … Continue reading All things nitric oxide – research report released→
The substance nitric oxide (NO), one of my favorite topics, is now known to be break-downable into components, one of which has one less electron. It’s known as NO(-) or HNO or nitroxyl, and researchers are finding some exciting new applications for it. One novel use for nitroxyl is as part of a nanoparticle coating … Continue reading New nitric oxide component (HNO) promises new CV help→
A recent experiment showed that exposing people to UV rays can measurably reduce their blood pressure. The conjecture is that the rays are promoting the transfer of nitric oxide via the skin into the circulation, thus lowering blood pressure along with risk of stroke and heart attack. Dermatologists were quick to say this doesn’t mean you … Continue reading Sunshine facilitates nitric oxide flow – and lowers blood pressure→
The first item is about nitric oxide (NO) used in testing, and the rest are all about using nanoparticles for delivering things into the human body, including NO. It’s astounding that scientists have found nanotechnology so helpful in these kinds of applications. I just hope more research is done on how safe it is to … Continue reading 5 news bits – nitric oxide and nanoparticles→
Another amazing use of nitric oxide (NO). A recent study found that injecting tiny beads filled with NO into the blood vessels of the penis in diabetic animals with induced Type 2 diabetes resulted in expanding the blood vessels in that organ. The expansion allowed for a dramatic improvement in sexual functioning. The researchers saw … Continue reading Nitric oxide beads promise to improve erectile dysfunction in diabetics→
Biomedical engineers at Drexel’s School of Biomedical Engineering, Science and Health Systems are busy constructing a mathematical model to explain how blood vessels regulate the flow of blood. Specifically they’re looking at the ways nitric oxide (NO) is produced by cells in our circulatory system, where it dilates blood vessels and thus controls blood pressure and flow. NO … Continue reading Nitric oxide is key to deciphering blood flow→
