A novel triblock copolymer of epsilon-caprolactone (CL) and ethylene oxide (E), CL6E90CL6, intended for use in implantable drug-delivery systems, has been subjected to gamma irradiation, in the solid state and in aqueous solution, under different controlled environmental conditions, to assess its
Hypoxia can induce chemoresistance, which is a significant clinical obstacle in cancer therapy. Here, we assessed development of hypoxia-induced chemoresistance (HICR) against free versus polymeric cisplatin micelles in a triple negative breast cancer cell line, MDA-MB-231. We then explored two
The syndrome of dialysis-associated leukopenia and complement activation by cellulosic membranes, including the so-called "first use syndrome", is reviewed and the pathophysiology of these phenomena is discussed. Subsequently the clinical side effects of hemodialysis, including dialysis-associated
During contact between blood and dialysis membrane after the first 20-30 minutes of haemodialysis there occur the complement activation, ++intra-dialysis thrombocytopenia and leucopenia, especially neutropenia following their degranulation, which results in liberation of a number of proteases and
The intradialytic symptoms that can be linked to components of the extracorporeal circuit of greatest clinical importance are the Type A (anaphylactoid) reactions. Most of these are IgE-mediated reactions due to ethylene oxide and are preventable by adequate degassing of the dialyzer by the
Global brain ischemia can lead to widespread neuronal death and poor neurologic outcomes in patients. Despite detailed understanding of the cellular and molecular mechanisms mediating neuronal death following focal and global brain hypoxia-ischemia, treatments to reduce ischemia-induced brain injury
