Physiological significance of antithrombin D-helix interaction with vascular GAGs.

Antithrombin (AT) is an anticoagulant serpin involved in the regulation of proteolytic activities of coagulation proteases. AT also possesses a direct anti-inflammatory function. The anticoagulant function of AT is mediated through its reactive-center loop (RCL)-dependent inhibition of coagulation proteases, but anti-inflammatory function of AT is mediated via its D-helix-dependent interaction with vascular glycosaminoglycans (GAGs).

Mussel-inspired modified regenerated cellulose as tissue adhesive and antibacterial gauze: A promising approach for rapid hemostasis in non-compressible hemorrhage.

Uncontrollable hemorrhage leads to high mortality rates; thus, engineering effective hemostatic materials is crucial for rapid hemostasis. Developing hemostatic materials for rapid coagulation, antibacterial activity, and easy removal without compromising clot integrity remains a challenge. Herein, a multifunctional hemostatic gauze was engineered by modifying regenerated cellulose textile through multiple sequential chemical reactions, including carboxymethylation, crosslinking with CaCl/ZnCl solution, oxidation, and polymerization with dopamine.

A probability model for estimating age in young individuals relative to key legal thresholds: 15, 18 or 21-year.

Age estimations are relevant for pre-trial detention, sentencing in criminal cases and as part of the evaluation in asylum processes to protect the rights and privileges of minors. No current method can determine an exact chronological age due to individual variations in biological development. This study seeks to develop a validated statistical model for estimating an age relative to key legal thresholds (15, 18, and 21 years) based on a skeletal (CT-clavicle, radiography-hand/wrist or MR-knee) and tooth (radiography-third molar) developmental stages.
