Induction of alveolar and bronchiolar phenotypes in human lung organoids.

Patient-derived organoids have revolutionized biomedical research and therapies by "transferring the patient into the Petri dish". In vitro access to human lung organoids representing distal lung tissue, i.e.

Effective Hemostasis in Severe Mesenteric Vein Laceration with Tachosil(®), using a Low- or Non-thrombogenic Patch to Prevent Tachosil(®)-induced Thrombosis.

Fibrinogen- and thrombin-coated collagen fleece (FTCC) facilitates surgical hemostasis, and is of particular value during resection of parenchymatous organs. Since thrombosis may ensue if the preparation is unintentionally applied intravascularly, it has not been recommended for treating lacerations of large veins, and no previous reports describe its use in vein repair. Our observations in two patients suggest, however, that FTCC might be indicated for hemostasis in vein injury where vascular suture is difficult or not possible, provided a low- or non-thrombogenic patch is interposed to prevent FTCC-induced vein thrombosis.
