Blood loss can be substantial and will influence morbidity and mortality after total knee arthroplasty. This study evaluated whether patient-specific instruments (PSI) can reduce blood loss because the intramedullary canal is not opened during the procedure and whether hidden blood loss can be reduced by its use. Seventy-five patients operated ...

The use of tourniquet in total knee arthroplasty (TKA) has resulted in negligible intra-operative blood loss but notable post-operative blood loss, creating the ideal scenario for using topical haemostatic agents intra-operatively. Recently, medical adjuvants including tranexamic acid (TXA) and hydrogen peroxide (H2O2) have been introduced. The aim of this study ...

Cortical flows mediate anteroposterior polarization in Caenorhabditis elegans by generating two mutually exclusive membrane domains. However, factors downstream of anteroposterior polarity that establish the dorsoventral axis remain elusive. Here, we show that rotational cortical flow orthogonal to the anteroposterior axis during the division of the AB blastomere in the two-cell ...

Blood transfusions are frequently required following total knee arthroplasty. Tranexamic acid (TXA) inhibits fibrinolysis and has been shown to reduce blood loss and transfusion requirements when delivered intravenously. Topical and intra-articular applications directly target bleeding sites whilst limiting systemic uptake and theoretically reduce the risk of thromboembolic complications. However, in ...

The brain responds to hypoxia with an increase in cerebral blood flow (CBF). Many mechanisms have been proposed for this hypoxic vasodilation, but none has gained universal acceptance. Although there is some disagreement about the shape of the relationship between arterial oxygen partial pressure (PaO(2)) and CBF, it is generally ...

Medicine today uses a wide range of biomaterials, most of which make contact with blood permanently or transiently upon implantation. Contact between blood and nonbiological materials or cells or tissue of nonhematologic origin initiates activation of the cascade systems (complement, contact activation/coagulation) of the blood, which induces platelet and leukocyte ...
