New study shows real-time stress reaction to racism

A new study by researchers from the University of Nebraska–Lincoln and University of Texas at Austin provides more evidence that the stress of racism contributes to health problems among people of color.

Which particulate air pollution poses the greatest health risk?

Researchers at the Paul Scherrer Institute (PSI), together with colleagues from several other European institutions, have investigated whether particulate matter from certain sources can be especially harmful to human health. ...

Scientists discover new concept of bacterial gene regulation

Bacteria are always with us: These tiny organisms are found within and on our body as is the case with all animals and plants. As part of a healthy microbiome they ensure our wellbeing. But if the microbial community gets ...

Transgenic rice lowers blood pressure of hypertensive rats

In the future, taking your blood pressure medication could be as simple as eating a spoonful of rice. This "treatment" could also have fewer side effects than current blood pressure medicines. As a first step, researchers ...

Blood pressure

Blood pressure (BP) is the pressure (force per unit area) exerted by circulating blood on the walls of blood vessels, and constitutes one of the principal vital signs. The pressure of the circulating blood decreases as it moves away from the heart through arteries and capillaries, and toward the heart through veins. When unqualified, the term blood pressure usually refers to brachial arterial pressure: that is, in the major blood vessel of the upper left or right arm that takes blood away from the heart. Blood pressure may, however, sometimes be measured at other sites in the body, for instance at the ankle. The ratio of the blood pressure measured in the main artery at the ankle to the brachial blood pressure gives the Ankle Brachial Pressure Index (ABPI).
