BACKGROUND Bleeding diathesis after aortic valve operation and ascending aorta replacement (AV-AA) is managed with fresh-frozen plasma (FFP) and platelet concentrates. The aim was to compare haemostatic effects of conventional transfusion management and FIBTEM (thromboelastometry test)-guided fibrinogen concentrate administration. METHODS A blood products transfusion algorithm was developed u...

Red meat from grass-fed animals, compared with concentrate-fed animals, contains increased concentrations of long-chain (LC) n-3 PUFA. However, the effects of red meat consumption from grass-fed animals on consumer blood concentrations of LC n-3 PUFA are unknown. The aim of the present study was to compare the effects on plasma and platelet LC n-3 PUFA status of consuming red meat produced from...

the risks of transmitting viral infection by blood and plasma-derived products have long been known and still remain an area of concern. in this study, in the process of purifying human factor vii from prothrombin complex, sid treatment using tri-n-butyl phosphate and tween 80 was employed and its capability and efficacy was studied. the results indicated that the process did not affect the bio...

The process of mullitization of kyanite concentrate was studied at different conditions of heat treatment (1400– 1600 °C and 0.5 – 3.5 hours) and particle size of raw materials (38-300 ?m). Kyanite concentrate was obtained fromore-dressing of kyanite deposits of Mishidowan-Bafgh region at 100 km northeastern part of Yazd. The results ofmicrostructure (shape, distribution and size of the grains)...

Bioengineering is an area of biotechnology that offers tools for different therapeutic strategies, including tissue therapies. For this, cells are associated with growth factors and scaffolds composed biocompatible biomaterials capable promoting the regeneration tissues, such as bones. Autologous produced from human peripheral blood have a proven ability to produce/release activating repair, po...

OBJECTIVES To identify the occurrence and the causes of platelet refractoriness in oncohematologic patients. INTRODUCTION Platelet refractoriness (unsatisfactory post-transfusion platelet increment) is a severe problem that impairs the treatment of oncohematologic patients and is not routinely investigated in most Brazilian services. METHODS Forty-four episodes of platelet concentrate trans...
