Measuring total testosterone level is the first-line approach in assessing androgen excess in women. The main pitfalls in measuring testosterone relate to its low concentration and to the structural similarity between circulating androgens and testosterone, requiring accurate techniques with high specificity and sensitivity. These goals can be achieved by immunoassay using a specific anti-testosterone monoclonal antibody, ideally after an extraction step. Liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS) will be commonly used for measuring testosterone, providing optimal accuracy with a low limit of detection...

BACKGROUND: Influenza immune globulin, manufactured from plasma of convalescent or vaccinated donors has been proposed as a potential therapy for severe influenza. In 2009, a program was initiated to collect plasma from donors who self-identified as having had H1N1 influenza or having received the H1N1 pandemic vaccine. The goal of this study was to determine the efficiency of donor screening by self-identification without antibody testing, and to evaluate demographic predictors of high-titer donations...

Pediatric kidney donors remain underutilized due to the high risk of postoperative thrombosis. To address this problem, we developed a novel en bloc kidney transplantation technique using donor thoracic aorta and the distal abdominal aorta as inflow and outflow tracts, respectively. Briefly, 8 kidneys from deceased infant donors under 5 months old and with low body weight (1.9-4.9 kg) were transplanted en bloc into 4 pediatric and 4 adult patients. The donor's common iliac artery or external iliac artery was anastomosed to the recipient's distal external iliac artery or inferior epigastric artery, respectively, as an outflow tract...

BACKGROUND: Cowpea (Vigna unguiculata) is an important source of protein supply for animal and human nutrition. The major storage globulins VICILIN and LEGUMIN (LEG) are synthesized from several genes including LEGA, LEGB, LEGJ and CVC (CONVICILIN). The current hypothesis is that the plant circadian core clock genes are conserved in a wide array of species and that primary metabolism is to a large extent controlled by the plant circadian clock. Our aim was to investigate a possible link between gene expression of storage proteins and the circadian clock...
