Researchers discovered a connection between elevated white blood cells in the saliva of healthy young adults and an early cardiovascular disease warning sign. What if detecting early indicators of cardiovascular disease was as simple as analyzing a saliva sample? Researchers believe they've discove
Researchers discovered that high levels of white blood cells in saliva, indicating gum inflammation, correlate with compromised flow-mediated dilation, a sign of poor arterial health. This link suggests even minor oral inflammation can affect cardiovascular health, emphasizing the connection between oral hygiene and heart health.
“We are starting to see more relationships between oral health and risk of cardiovascular disease,” said Ker-Yung Hong, first author of the study, now studying dentistry at the University of Western Ontario. “If we are seeing that oral health may have an impact on the risk of developing cardiovascular disease even in young healthy individuals, this holistic approach can be implemented earlier on.”
At the lab, participants rinsed their mouths with water before rinsing their mouths with saline which was collected for analysis. Participants then laid down for 10 minutes for an electrocardiogram, and stayed lying down for another 10 minutes so that the scientists could take their blood pressure, flow-mediated dilation, and pulse-wave velocity.

Researchers estimate anthropogenic mercury emissions from 1500 to 1900Mercury, toxic to humans, is the only known metallic element that is liquid at standard Earth temperature and pressure and therefore comprises a hazard to children because it is so cool. But many historic human activities have involved the use of mercury, including gold and silver mining, the production of the red pigment vermilion, felt production, and manufacture of mechanical pressure gauges, thermometers and other devices. One guy even made a mercury fountain for the Spanish Pavilion at the 1937 World Exhibition in Paris, now on display at the Fundació Joan Miró in Barcelona.
