Heparin-stimulated inhibition of factor IXa generation and factor IXa neutralization in plasma [PDF]
Generation and inhibition of activated factor IXa was studied in factor XIa-activated plasma containing 4 mmol/L free calcium ions and 20 mumol/L phospholipid (25 mol% phosphatidylserine/75 mol% phosphatidylcholine). Interference of other (activated) clotting factors with the factor IXa activity measurements could be avoided by using a highly specific ...

Factor IXa Inhibitors as Novel Anticoagulants [PDF]
Currently available anticoagulants are limited by modest therapeutic benefits, narrow clinical applications, increased bleeding risk, and drug-induced thrombophilia. Because factor IX plays a pivotal role in tissue factor (TF)–mediated thrombin generation, it may represent a promising target for drug development.

Porcine Corneal Tissue and Xenozoonotic Risks: A Review of the Current Evidence. [PDF]
ABSTRACT Corneal opacities affect millions worldwide, with corneal transplantation as the primary treatment. However, donor shortages remain a challenge, leaving thousands waiting for transplants. Xenotransplantation using porcine corneas has emerged as a promising alternative due to anatomical and physiological similarities with human corneas ...
