The bacteria, fusobacterium nucleatum (F. nucleatum), proliferates in periodontal disease and affects the gums and jawbone. If untreated, it results in unstable teeth and tooth loss. In recent years, studies have linked F. nucleatum to conditions ranging from colorectal cancer to premature delivery of babies. “In this study, our lab is the first to find that Fusobacterium nucleatum can generate systemic inflammation and...
In a paper in the journal Nano Energy, researchers describe their invention, built via 3D printing of nanomaterials on flexible substrates for real-time and wireless monitoring of vital signs. The current prototype serves as a self-powered radial artery pulse monitor, but other aspects of health—such as heart rate, body temperature, or blood pressure—can be gauged by simply changing...

UNIVERSITY OF MISSOURI-COLUMBIA Annual screenings of patients at high risk for lung cancer can catch tumors early and improve a patient’s long-term prognosis. However, low-dose computer tomography (LDCT) has a high false-positive rate that can lead to unnecessary biopsies. University of Missouri School of Medicine researchers have found a biomarker in the blood that can...
by McGill University Health Centre Credit: Pixabay/CC0 Public Domain Affecting up to four percent of the population and mostly women, fibromyalgia is a syndrome that causes pain, fatigue and cognitive issues. Poorly understood, the condition has no cure and is difficult to diagnose. Now, thanks to the work of a team of scientists from the...
by Iqbal Pittalwala, University of California – Riverside Credit: Pixabay/CC0 Public Domain Some studies have suggested electronic cigarette (EC) use may be a healthier alternative to cigarette smoking. A University of California, Riverside, study shows this is far from the case. The researchers report in the journal Toxics that switching from combustible cigarettes to ECs does not...
by Noah Fromson, University of Michigan Credit: Pixabay/CC0 Public Domain Researchers have developed a noninvasive method to identify a potential cause of hypertension with a drastic reduction in radiation exposure, a study shows. Around 10-15% cases of hypertension, or high blood pressure, are believed to be caused by excessive production of the hormone aldosterone, which affects the...
