BACKGROUND Hematopoietic stem-cell transplantation is a well-established treatment in various hematologic malignancies, but the outcome depends on disease relapse, infections, and the development and severity of acute and chronic graft-versus-host disease. Some evidence has revealed an important role for the nonclassical major histocompatibility complex(More)
BACKGROUND In recent years various studies showed, that hepatitis E virus (HEV) is a growing public health problem in many developed countries. Therefore, HEV infections might bear a transmission risk by blood transfusions. The clinical relevance still requires further investigations. The aim of this study was to provide an overview of acute HEV infections(More)
BACKGROUND Aberrant RHD alleles leading to a reduced expression of D antigen on the red blood cell (RBC) surface may be mistyped as D- by serology. To quantify the occurrence of weak D, DEL, and D+/- chimera among apparent D- first-time blood donors, polymerase chain reaction (PCR) screening was implemented as a routine service. STUDY DESIGN AND METHODS A(More)
How cells coordinate the immune system activities is important for potentially life-saving organ or stem cell transplantations. Polymorphic immunoregulatory genes, many of them located in the human major histocompatibility complex, impact the process and assure the proper execution of tolerance-versus-activity mechanisms. In haematopoietic stem cell(More)
Transplantation and, notably, hematopoietic stem cell transplantation require high-resolution human leukocyte antigen (HLA) typing and, because of the heterozygous genomic DNA samples, are dependent on clonal analytical methods. High-resolution HLA typing is a necessity for accomplishing the best possible histocompatibility match between donor and(More)
Adipose tissue is easily available and contains high numbers of stem cells that are capable for chondrogenic differentiation. We hypothesize that a partial substitution of chondrocytes with autologous adipose-derived stem cells (ASC) might be a possible strategy to reduce the number of chondrocytes needed in matrix-associated autologous chondrocyte(More)
BACKGROUND AND OBJECTIVES Molecular variations of the RHD gene may result in the reduced expression of the D antigen and altered Rh phenotypes. In many occasions, they cannot be typed reliably by standard serological methods. Sequence-based typing is the gold standard to determine rare and unknown RHD genotypes. For this pilot study, sequence-based typing(More)
This study evaluated the suitability of adipose-derived stem cells (ASCs) combined with fibrin matrix of variable composition for adipose tissue-equivalent formation in vitro. Therefore, undifferentiated ASCs were embedded in fibrin clots composed of 2 IU/ml thrombin and fibrinogen of varying concentrations (6.25, 12.5 and 25 mg/ml) and kept under control(More)
Bovine digital dermatitis (BDD) is a common infectious foot disease whose aetiology is not fully understood. Its origin is thought to be multifactorial, with treponemes being involved. Using PCR-based techniques, BDD samples from 45 affected cows and intact skin from 8 BDD-affected and 33 healthy cows were assessed for the presence of bovine papillomavirus(More)
BACKGROUND AND OBJECTIVE Genotyping may be applied for rare blood group polymorphisms in a high-throughput mode as well for the molecular determination of blood groups due to unclear serological results. MATERIAL AND METHODS We developed and validated a DNA typing method for the determination of KEL1/2, JK1/2, FY1/2, FY0, MNS1/2, MNS3/4, DO1/2, CO1/2 and(More)
