The peptide hormone prolactin (PRL) is produced by specialized cells in the anterior pituitary gland and in a number of sites outside the pituitary. Its biological actions consist of various roles in reproduction, lactation, and of a number of homeostatic biological activities that also include immune functions. Elevated serum PRL concentrations often(More)
BACKGROUND Almost 99% of the body magnesium is inside cells. The concentration of intracellular ionized magnesium (iMg) is physiologically relevant. iMg in erythrocytes is a new parameter that can help to establish reliable information on the functional magnesium status. METHODS iMg concentration in erythrocytes and serum was measured by ion-selective(More)
BACKGROUND Usually, a predonation hemoglobin (Hb) measurement must precede blood donation. Hb values of a donor's previous donation might be used for selecting a subgroup in which predonation Hb measurements are unnecessary. STUDY DESIGN AND METHODS Only donors with historical Hb values below 129 or 139 g per L for female and male donors, respectively,(More)
Systemic lupus erythematosus (SLE), an autoimmune disease characterized by chronic nephritis, arthritis and dermatitis, and the presence of antinuclear autoantibodies, is associated with complement factor deficiencies in the classical activation pathway. In addition, IFN-alpha seems to be a key cytokine in SLE as an activated IFN-alpha system is regularly(More)
OBJECTIVE To determine whether the implementation of patient blood management (PBM) is effective to decrease the use of red blood cell without impairment of patient's safety. BACKGROUND The World Health Organization encouraged all member states to implement PBM programs employing multiple combined strategies to increase and preserve autologous erythrocyte(More)
BACKGROUND The aim of this study was to evaluate the optimal preanalytical conditions prior to nucleic acid amplification technology (NAT) for human immunodeficiency virus-1 (HIV-1) or Hepatitis C virus (HCV) RNA in pools of 96 plasma specimens with regard to storage temperature, time and plasma separation in a blood donation environment. STUDY DESIGN AND(More)
BACKGROUND DNA of human cytomegalovirus (CMV) is frequently detected in plasma of donors with primary CMV infection. It is unknown, however, whether leukoreduced blood products from these donors contain sufficient amounts of infectious virus to cause transfusion-transmitted CMV infections (TT-CMV). STUDY DESIGN AND METHODS During a 14-year period, CMV(More)
