Recombinant factor VIII and factor IX concentrates, human-plasma-derived albumin, and samples from previously untreated patients with hemophilia were examined for the presence of TT virus (TTV) by using polymerase chain reaction testing. Blood samples from the patients were obtained prospectively before and every 3 to 6 months after therapy was begun. TTV was detected in 23.5% of the recombinan...

In previous studies, we have shown that some, but not all low-, intermediate-, and high-purity factor VIII concentrates inhibit interleukin-2 (IL-2) secretion from phytohemagglutinin (PHA)-stimulated T lymphocytes. We now present evidence that this inhibitory action of concentrates is, at least in part, due to contamination with transforming growth factor-beta (TGF-beta). Originally identified ...

There is an ongoing debate whether platelet concentrates (PCs) prepared from either whole-blood donations or by plateletpheresis are superior. Usage of these two product types varies greatly between countries and individual institutions. Some use mainly apheresis PCs; others prefer pooled PCs which are produced from whole-blood donations. This review summarizes the existing information on these...

Background Incidence and mortality from traumatic intra-cranial haemorrhage (ICH) is increased in patients on warfarin [1]. Prothrombin Complex Concentrates (PCC) rapidly reverse warfarin anti-coagulation and have been shown to reduce haematoma expansion and mortality in warfarinised patients sustaining ICH [2]. We aimed to determine the feasibility of pre-hospital use of PCCs by physicians and...

Abstract Concentrate withdrawal and feed restriction reduce milk production to facilitate dry-off. We investigated the impact of rations providing different amounts nutrients in combination with on performance, endocrine, metabolic responses before after abrupt Forty-three cows were studied from d 12 until 6 dry-off (56 scheduled calving). Cows fed experimental concentrates rich either crude pr...
