The self-assembly of fibrin is a vital process in blood clotting, primarily facilitated by the interactions between knobs "A" and "B" in the central E region of one molecule and the corresponding holes "a" and "b" in the peripheral D regions of two other fibrin molecules. However, the precise function of the interactions between knob "B" and hole "b" during fibrin polymerization remains a subject of ongoing debate. The present study focuses on investigating intermolecular interactions between knob "B" and hole "b".

The presented work is dedicated to the detection of hydrogen, using detectors based on a MAPD (Micropixel Avalanche Photodiode) array based on new MAPD-3NM-2 type photodiodes and two different scintillators (LaBr(Ce) and LSO(Ce)). The physical parameters of the MAPD photodiode used in the study and the intrinsic background of the scintillators were investigated. For the 2.

This investigation is crucial while the conversion of fibrinogen into fibrin induces conformational changes that expose binding sites for Pg and tissue-type Pg activator (tPA), facilitating effective zymogen activation on the fibrin surface.
Methods: Two C-terminal fragments of the Aα chain ‒ 45 kDa (225Val-610Val) and 40 kDa (225Val-580Lys), were obtained through plasmin hydrolysis of human fibrinogen and subsequently characterized using MALDI TOF mass spectrometry.
