BACKGROUND: Serine proteases are important virulence factors for many pathogens. Recently, we discovered a group of trypsin-like serine proteases with domain organization unique to flatworm parasites and containing a thrombospondin type 1 repeat (TSR-1). These proteases are recognized as antigens during host infection and may prove useful as anthelminthic vaccines, however their molecular characteristics are under-studied. Here, we characterize the structural and proteolytic attributes of serine protease 2 (SmSP2) from Schistosoma mansoni, one of the major species responsible for the tropical infectious disease, schistosomiasis...

A 71-year-old male presented to our institution with cholestatic hepatitis after having recently undergone upper endoscopy for treatment of gastrointestinal bleeding. Further investigation with endoscopic retrograde cholangiopancreatography revealed a hemostatic clip on the ampulla of Vater. After initial attempts at cannulation of the common bile duct were unsuccessful, biliary decompression was achieved by use of needle-knife fistulotomy. A common bile duct stent was placed and the liver function tests improved prior to discharge...

Fibrinolysis is a complex process that controls both hemostasis and thrombosis. The regulation of the fibrinolytic system is mediated through a wide array of cofactors and inhibitors that maintain the hemostatic balance in a delicate equilibrium. As a consequence, disturbances in the fibrinolysis pathway are associated with various disease states, ranging from thrombotic to hemorrhagic clinical phenotypes. In particular, a number of inherited and acquired disorders are associated with an enhanced fibrinolysis leading to a bleeding tendency that in some cases may be life-threatening...

BACKGROUND: Liver transplantation has become commonplace for patients with end-stage liver disease. The liver is a bodily organ of great importance, and its dysfunction can cause significant complications throughout the body. Patients with hepatic disease should be able to acquire knowledge of the physiology of the liver via the dental profession, and it is also necessary to modify some aspects of dental treatment even in healthy patients. Problems such as excessive bleeding and hepatotoxicity caused by some of the drugs used in dental treatment can lead to a decrease in systemic health...

Intraoperative surgical sealants and hemostatic agents have been shown to reduce postoperative complications, transfusions and hospital resource utilization. Despite availability of these agents, the incidence and burden of bleeding remains high and surgeons' requirements for hemostatic control continue to evolve. A burgeoning class of hemostatic agents are hemostatic patches, which offer package-to-patient readiness and direct application. In addition, hemostatic patches may provide tissue sealing capabilities...

Ticks salivate while feeding on their hosts. Saliva helps blood feeding through host anti-hemostatic and immunomodulatory components. Previous transcriptomic and proteomic studies revealed the complexity of tick saliva, comprising hundreds of polypeptides grouped in several multi-genic families such as lipocalins, Kunitz-domain containing peptides, metalloproteases, basic tail secreted proteins, and several other families uniquely found in ticks. These studies also revealed that the composition of saliva changes with time; expression of transcripts from the same family wax and wane as a function of feeding time...

BACKGROUND: Emicizumab is an anti-factor (F)IXa/FX bispecific antibody that mimics FVIIIa cofactor function. Emicizumab does not require activation by thrombin and its effect on shortening activated partial prothrombin time (aPTT) is much greater relative to FVIII. The aPTT has limited utility, therefore, in hemophilia A patients (HA-pts) treated with emicizumab. AIM: To evaluate the global coagulation potential of emicizumab. METHODS: Clot waveform analysis (CWA) with prothrombin time (PT)/aPTT-mixed reagents was used to define hemostatic monitoring protocols in HA-pts...

The presacral venous system is located under the pelvic fascia covering the anterior of the sacrum and consists of two lateral sacral veins, middle sacral vein, and the veins that communicate them. The presacral venous system can be easily damaged and causes serious bleeding which is difficult to control and may cause intraoperative mortality. Its incidence varies between 3% and 9.4%. Although several methods have been tried to control presacral bleeding, the definitive method of treatment has not yet been identified...

OBJECTIVE: Laparoscopic cholecystectomy is the first-choice treatment for symptomatic cholelithiasis. Though generally safe, this procedure is not without complications, with bleeding the most frequent cause of conversion to open cholecystectomy. Oxidized regenerated cellulose (ORC) added to conventional hemostatic strategies, is widely used to control bleeding during surgery despite limited evidence supporting its use. This retrospective study analyzed patients undergoing laparoscopic cholecystectomy in an Italian center over a 16-month period, between October 2014 and February 2016, who experienced uncontrollable bleeding despite the use of conventional hemostatic strategies, requiring the addition of ORC gauze (Emosist® )...

PURPOSE: Tranexamic acid (TXA) is widely used in the prevention of postsurgical oral bleeding. Tranexamic acid in addition to further surgical measures is widely utilized in prevention of post-surgical oral bleeding. The aim of the present study was to investigate: Can oral hemostasis be achieved by merely compression and topical application of tranexamic acid in different anticoagulant regimes among patients attending a general emergency department? Where are the limits to this procedure? Which has the greater impact on surgeons' choice for an invasive hemostatic approach-bleeding quality or oral anticoagulant therapy? MATERIALS AND METHODS: A retrospective cohort study of 542 patients who consecutively received treatment for oral bleeding was performed...
