Clotting is initiated by two processes or pathways - a slower but larger intrinsic pathway (contact activation pathway) or a very rapid extrinsic pathway (tissue factor pathway) - which lead to ...

When skin is cut or damaged, tiny cell fragments circulating in the blood, called platelets, arrive at the injury and spread out to stop the blood from leaking out. Once enough layers of platelets ...

Blood clotting is a life-saving process, but too much or too little can be dangerous. A groundbreaking study now unveils a hidden secret—two distinct pathways control clot formation. This ...

Disseminated intravascular coagulation is a bleeding disorder characterized by two seemingly opposite conditions. As a caregiver in a neonatal intensive care unit (NICU), it is not uncommon to ...

Factor XI Inhibitors are the alternative to DOACs, which are highly effective at preventing strokes. However, their bleeding risks often limit their use, especially in high-risk patients.
