introduction: acute leukemia is the most common malignancy in children and acute lymphoblastic leukemia (all) accounts for 75% of acute leukemia cases. new treatment protocols have resulted in complete remission rates up to nearly 100% in children with acute lymphoblastic leukemia. today, one of the most important prognostic factors in acute lymphoblastic leukemia is intensity of the treatment....

HLA class I tetramers have revolutionized the study of Ag-specific CD8+ T cell responses. Technical problems and the rarity of Ag-specific CD4+ Th cells have not allowed the potential of HLA class II tetramers to be fully realized. Here, we optimize HLA class II tetramer staining methods through the use of a comprehensive panel of HIV-, influenza-, CMV-, and tetanus toxoid-specific tetramers. W...

BACKGROUND Background and objective. We investigated immune recovery in 50 patients given either unmanipulated or CD8-depleted allogeneic peripheral blood stem cells after non-myeloablative conditioning. DESIGN AND METHODS Fifty patients were randomized to receive either CD8-depleted (n=22) or non-manipulated (n=28) peripheral blood stem cells. The median patients age was 57 (range 36-69) yea...

contamination sites of pseudomonas fluorescenswere traced in the production line for milk pasteurization in a large dairy plant in shiraz, iran. samples of raw and pasteurized milk were collected at six sites along the line. all milk samples were incubated at 7°c until the aerobic plate count had reached 10 6 -10 7 cfu ml-1. colonies were picked randomly and identified. no growth of gram negati...

The widespread usage of electronic health records (EHRs) for clinical research has produced multiple electronic phenotyping approaches. Methods for electronic phenotyping range from those needing extensive specialized medical expert supervision to those based on semi-supervised learning techniques. We present Automated PHenotype Routine for Observational Definition, Identification, Training and...

Background: Human T cell lymphotropic virus type I (HTLV-I)-associated myelopa-thy/tropical spastic paraparesis (HAM/TSP) is an inflammatory disease which occurs in less than 2% of HTLV-I -infected individuals. High proviral load, high HTLV-I-specific CD8+ cytotoxic T lymphocyte frequency (CTL) and host genetic factors such as HLA all appear to be associated with HTLV-I infection. Previous stud...

Over a period of three years we determined haptoglobin levels by single radial immunodiffusion (RID) and the haptoglobin phenotype in over 1700 samples of patients suspected of a haemolytic disease. As haptoglobin phenotyping is rather laborious and therefore an expensive method, we re-evaluated the diagnostic need for phenotyping. From our reference values for the respective phenotypes of hapt...
