Tips to avoiding blood clots and improving blood storage for transfusions

Hibernating mammals are amazing! How in the world do they prevent blood clots when they not only reduce their body temperature but also their blood flow during hibernation? That question is precisely what a new study published in Physiological Genomics examined.   Typically, cold temperatures are known to activate the process of blood clotting by stimulating platelets. Platelets are sticky cells without a nucleus that circulate in the blood. When […]

For this reason, antiplatelet medications are commonly prescribed for people at risk of developing blood clots, or who have already developed one. Many of the medications that are currently on the market to treat blood clots come with a risk for excessive bleeding and reduced platelet numbers. Researchers have now discovered an effective antiplatelet protein in snake venom that is not associated excessive bleeding. […]
