An important role has been ascribed to plasma factor XIII (FXIII) in inflammation and wound healing. FXIII is necessary for fibrin stabilization and interacts with connective tissue and adhesive proteins and cells. In a prospective study, FXIII activity and parameters of coagulation, fibrinolysis and inflammation, were determined in patients with ulcerative(More)
Activation of coagulation and fibrinolysis within tumour tissues is thought to be associated with tumour growth, angiogenesis, and metastasis. The plasma levels of markers of thrombin and plasmin generation are sensitive tools for monitoring activation of coagulation and fibrinolysis. We studied 47 patients with histologically confirmed lung cancer, 15 with(More)
Sub-fossilised remains may still contain highly degraded ancient DNA (aDNA) useful for palaeogenetic investigations. Whether X-ray computed [micro-] tomography ([μ]CT) imaging of these fossils may further damage aDNA remains debated. Although the effect of X-ray on DNA in living organisms is well documented, its impact on aDNA molecules is unexplored. Here(More)
BACKGROUND There is evidence that activation of coagulation by influencing tumour biology may have impact on clinical course of lung cancer. PATIENTS AND METHODS We measured the activation markers thrombin-antithrombin complex (TAT) and prothrombin fragment F1 + 2 in 99 lung cancer patients immediately after diagnosis, before antineoplastic treatment.(More)
Both plasmin and elastase, a protease released from neutrophil granulocytes, are known to degrade fibrin(ogen). This raises the possibility that elevated plasma levels of split products such as D-dimer may in part result from elastase action. After incubation in vitro of fibrinogen and fibrin clots with elastase, a clearcut increase of D-dimer(More)
The two living species of bison (European and American) are among the few terrestrial megafauna to have survived the late Pleistocene extinctions. Despite the extensive bovid fossil record in Eurasia, the evolutionary history of the European bison (or wisent, Bison bonasus) before the Holocene (<11.7 thousand years ago (kya)) remains a mystery. We use(More)
The giant deer Megaloceros giganteus is among the most fascinating Late Pleistocene Eurasian megafauna that became extinct at the end of the last ice age. Important questions persist regarding its phylogenetic relationship to contemporary taxa and the reasons for its extinction. We analyzed two large ancient cervid bone fragments recovered from cave sites(More)

Tumor matrix generation and tumor cell growth are supported by coagulation processes within the tumor tissue. Activators of coagulation were searched for in suspensions of 9 permanent human squamous-cell lung-cancer (EPLC 32MI, U1752), large-cell lung-cancer (LCLC 97TMI, LCLC 103H, U1810), and small-cell lung-cancer (N-592, H-526, DMS79, 86MI) cell lines.(More)
