Abstract Psychopathy is a personality construct characterized by emotional detachment, impulsivity, and antisocial tendencies. Despite a clinical prevalence of 1%, the biological underpinnings of psychopathy remain poorly understood. Emerging evidence suggests a role for the microbiota-brain axis in personality and behavior, yet its relevance to psychopathy remains unexplored.

A Chromatographic Approach for Simultaneous Quantification of Multiple Anticoagulants in Human Plasma Samples

| Wiley Online Library Verified
1 Introduction Anticoagulants represent a key therapeutic approach to the prevention and treatment of thromboembolic conditions in venous and arterial pathways [1-3]. These drugs work by targeting the clotting process, either through direct inhibition of fundamental enzymes like thrombin or factor Xa (FXa), or indirectly by enhancing natural anticoagulant mechanisms and reducing the production of vitamin K-dependent factors [2, 4, 5].

What is already known about this subject The minimum effective plasma TXA to inhibit fibrinolysis is generally 5–10 μg/mL for partial inhibition, with concentrations above 10 μg/mL required for near-complete suppression. Monitoring and adjusting TXA dosing during scoliosis surgery is essential; the precise TXA dosing required to consistently achieve this threshold in vivo remains unclear and may vary with patient and surgical factors.
