Liver injuries caused by high voltage electricity are rare and result in high mortality and morbidity. They are produced by the resistance to the passage of electrical current through the tissue, which creates heat that leads to coagulation necrosis and rupture of the cell membrane. We present a case of an electrical injury to the liver, diagnosed by ultrasound and CT in a 39-year-old man who p...

introduction: the main inhibitors of coagulation pathway are antithrombin (at), protein c and protein s. these inhibitors are necessary to prevent thromboembolism. hereditary deficiency of inhibitors is the main cause of alteration in balance between the anti-clotting and the formation of thrombin. patients with this abnormality are susceptible to venous thromboembolism (vte). two major clinica...

background some of the dental procedures can cause bleeding. bleeding control can be difficult in some patients because of systemic disease or chronic anticoagulant therapy, so they may be at increased risk for bleeding occurrences or even death following invasive dental procedures. this study was schemed to measure the knowledge of general dentists in shiraz city regarding coagulation tests pe...

This review article summarizes the main results of recent fundamental research on the electrical charging of nanometer-sized aerosol particles (particle diameter below 10 nm, Knudsen number above about 15, kinetic regime). It covers topics of great relevance to aerosol processing and measurement, such as the effect of the presence of a number of ions on the surface of a nanoparticle on its elec...

BACKGROUND Adequate hemostasis in cranial and spinal tumor surgery is of paramount importance in neurosurgical practice. Generalized ooze bleeding from the surgical walls cavity, coming from neoplastic vessels or nervous tissue, may be problematic. Recent technical advances have dramatically reduced intraoperative complications related to blood loss. Several techniques are usually employed to c...

Although graphene oxide (GO) has been used in multidisciplinary areas due to its excellent physicochemical properties, its environmental behavior and fate are still largely unclear. In this study, batch experiments, spectroscopy analysis and theoretical calculations were addressed to promote a more comprehensive understanding toward the coagulation behavior of GO onto TiO2 under various environ...

Arsenic removal from high-arsenic water in a mine drainage system has been studied through an enhanced coagulation process with ferric ions and coarse calcite (38-74 microm) in this work. The experimental results have shown that arsenic-borne coagulates produced by coagulation with ferric ions alone were very fine, so micro-filtration (membrane as filter medium) was needed to remove the coagula...

conclusions an hb-driven algorithm, in combination with the “coagulation box” and the early use of clotting factors, could be a simple and effective tool for improving coagulopathy in multiple trauma patients. results over a 12-month investigation period, 123 severe multiple trauma patients needing intensive care therapy were admitted to our trauma center (mean age 48 years, mean iss (injury se...

Low temperature plasma (LTP) coagulation equipment, which avoids causing burn injuries to patients, has been introducing into minimally invasive surgery. The mechanism by which this equipment stops bleeding is to directly occupy the injury with the formed blood clots, and different from the mechanism of the common electrical hemostatic devices that cauterize the tissues around the bleeding to s...
