Journal ArticleDOI
Retinal Arterial Obstruction in Children and Young Adults
TL;DR: The records of 27 patients who developed retinal arterial obstruction (RAO) prior to the age of 30 years were studied to ascertain associated systemic and ocular findings as possible etiologic factors.
Journal ArticleDOI
Comparison of bleeding tendency, factor XI coagulant activity, and factor XI antigen in 25 factor XI-deficient kindreds
TL;DR: In conclusion, bleeding tendency appears to be consistent within a given kindred and is not determined exclusively by factor XI:C orfactor XI:Ag levels.
Journal ArticleDOI
Metabolism and function of human platelets washed by albumin density gradient separation.
TL;DR: In this article, platelets are sedimented into a continuous density gradient of isosmolar albumin containing apyrase to protect them from clumping and physical injury and are resuspended in calcium-free Tyrode's solution.
Journal ArticleDOI
Contributions of human platelets to the proteolytic activation of blood coagulation factors XII and XI
TL;DR: In this article, isolated platelets were tested for their capacity to promote the activation and cleavage of purified factors XII and XI in various mixtures of purified factor XII, kallikrein, high molecular weight (HMW) kininogen, and factor XI.
Journal ArticleDOI
Factor XI contributes to thrombin generation in the absence of factor XII
Dmitri V. Kravtsov,Anton Matafonov,Erik I. Tucker,Mao Fu Sun,Peter N. Walsh,Andras Gruber,David Gailani +6 more
TL;DR: Using plasma in which fXII is either inhibited or absent, it is shown that fXI contributes to plasma thrombin generation when coagulation is initiated with low concentrations of tissue factor, factor Xa, or alpha-thrombin.
