An average cystic fibrosis (CF) carrier frequency of 1 in 25 in Europe is cited in numerous reports, although a great variability in estimated prevalences has been found in different European populations. The estimates of these frequencies were based on numbers of CF patients before identification of the gene in 1989. Here we report the results of a study(More)
Platelet aggregation in response to ADP (10 µM) and collagen (4 µg/ml) in fresh and stored platelet concentrates (PC) and the enhancement of aggregation of the stored platelets after resuspension in fresh plasma and plasma-free medium were measured. The ability of platelets in autologous plasma to respond to the two agonists decreased significantly on days(More)
Temporal changes in serum S-100 protein levels were compared between patients with ischemic stroke, transient ischemic attack (TIA) and traumatic brain injury (TBI). In addition, S-100 levels were correlated with clinical severity and outcome. Measurements were done with a LIA-mat((R)) Sangtec((R)) 100 using an automated immunoluminometric assay. Serum(More)
ADP-induced platelet aggregation was studied for up to six weeks in 34 patients with head injuries. The patients were divided into three groups according to the degree of impaired consciousness assessed by a clinical coma scale, and change in platelet aggregation was related to the coma score. Platelet aggregation was markedly reduced in all eight patients(More)
Mouthwashes can be used as a DNA resource for mutation detection and, because collection and DNA isolation is simple and cheap, they could in particular, be used for large numbers of samples. To determine the failure rate (the proportion of mouth samples in which no PCR product was obtained) and the specificity of buccal epithelial cell mutation detection(More)
For safe blood transfusion, developing countries face considerable problems including serological screening and confirmation of blood-borne virus infections (HCV, HTLV-I, HIV and HBsAg). Confirmation tests are not only costly but also require sophisticated techniques and expertise. In order to provide this support we have attempted to perform a virus(More)
In view of the currently available data, prevention of alloimmunization requires filters with higher efficiency to achieve a reduction in the number of leukocytes below 10 million per transfusion. Two versions (Pall PL-100 and PL-50) of the new generation leukocyte-depletion filters were studied. Single donor (SDPC)- and pooled multiple donor (MDPC)(More)
