Saving Lives By Averting Stroke Probably With Safe, Simple Eye Test

Posted:

Lurking possibility of a simple eye test to offer an effective way to spot patients vulnerable to high risk for stroke, posit researchers at the University of Zurich. They showed that a test called ocular pulse amplitude (OPA) can reliably detect carotid artery stenosis (CAS), a condition that clogs or blocks the arteries that feed the front part of the brain. It's a known risk factor for stroke. The OPA test could be performed by ophthalmologists - physicians who treat eye ...

Tears: Longer We Cry, Hotter They Get

Posted:

When a person cries for a longer period, the tears tend to get warmer, as revealed by a new study. A new model of the fluid dynamics and heat flow in human tears has been created by mathematicians from the University of Delaware in the US. When people blink their eyes - the formation point of a tear - a thin liquid film is spread across the surface of the eye. The surface of the tear film then cools slightly, and for dry-eyed patients the ...

Chances of 3 Kinds Of Foetal Cells Migration Into Maternal Organs in Pregnancy

Posted:

Pregnant woman's blood stream, in addition to holding her own cells, also harbours small number of her child's and few of those linger in her internal organs long after birthing the baby. Understanding the origin and identity of these cells is vital to understanding their potential effects on a mother's long-term health. For example, fetal cells have been found at tumor sites in mothers, but it is unknown whether the cells are helping to destroy the tumor or to speed its growth. ...
