BACKGROUND AND OBJECTIVES The present general plasticizer di-2-ethylhexyl-phthalate in polyvinylchloride (PVC) blood bags is only physically dispersed in PVC and will therefore leach into blood components. The objective of this study was to perform a first preliminary red blood cell (RBC) storage evaluation in a new blood bag manufactured of polyolefin without any inclusion of potentially migra...
Mucopolysaccharidosis VII (MPS VII) is a lysosomal storage disease due to deficient activity of beta-glucuronidase (GUSB) that results in accumulation of glycosaminoglycans in many organs. We have previously reported that neonatal intravenous injection of a gamma retroviral vector (RV) expressing canine GUSB resulted in transduction of hepatocytes, high levels of GUSB modified with mannose 6-ph...
BACKGROUND The relation between elevated blood lactate level and mortality and morbidity rates after coronary bypass surgery is a proven subject. One of the factors that seems to affect directly the blood lactate level is the storage duration of packed red blood cells. OBJECTIVES This study aimed to evaluate the effect of storage duration of transfused blood on serum lactate during cardiac su...
Background: Platelet storage is complicated by deleterious changes that cause progressive structural and functional damages, so-called platelet storage lesion (PSL). PSL is commonly manifested by augmented platelet activation which is also associated with the increased levels of reactive oxygen species (ROS). Whether ROS generation increases during the storage of platelet concentrates and wheth...
It has been shown that red cells of blood collected in acid-citrate-dextrose (ACD) undergo changes in their dimensions, osmotic fragility, permeability and metabolism during storage at 4° C (1). Information concerning the effect of storage on the physical and chemical states of soluble red cell proteins, particularly hemoglobin, is not available. Such data may be of interest in view of the mark...
Abstract Background and Objectives Platelets release microparticles containing cellular components, including microRNAs, during storage. Assessment of these microRNAs is one of the markers for evaluation of platelet storage lesions. The aim of the present study was to evaluate the level of changes in the expression of mir-223, mir-92a and mir-222 during storage in platelets prepared by platele...
the effects of coatingtreatments (waxand plasticbags) combined with methylsalicylate on the fruit quality and chilling injury of moro blood orange were studied during storage. treated fruits were kept in storage for 80 days at 5 oc and 90-95% relative humidity. some characteristics such as pulp and skin total phenolics, antioxidant capacity, total anthocyanin, lipid peroxidation, and the chilli...
BACKGROUND Red blood cell (RBC) alloimmunization is a major immunologic risk of transfusion. However, RBC storage facilitates white blood cell (WBC) apoptosis and apoptotic cells have immunomodulatory properties. We investigated the behavior of WBCs, and apoptosis in particular, in RBC units during storage and then studied the impact of WBC apoptosis on the modulation of posttransfusion alloimm...
Background: Major platelet adhesive receptors that contribute significantly to thrombus formation include platelet receptor glycoprotein Ibα (GPIbα) of the GPIb-IX-V complex and platelet glycoprotein VI (GPVI). GPIbα plays a crucial role in platelet tethering to sub-endothelial matrix, which initiates thrombus formation at arterial shear rates, whereas GPVI is critically involved in platelets f...
