The heterodimeric peptide hormone relaxin acts through the novel G-protein coupled receptor LGR7 to elicit the production of cAMP in the human monocyte cell line THP-1. The very small number of receptors on the cell surface, and the lack of response in cell membranes imply the involvement of a cytoplasmic signal amplification process. Here we show that this(More)
The hypothalamic-pituitary-gonadal (HPG) axis comprises pulsatile GnRH from the hypothalamus impacting on the anterior pituitary to induce expression and release of both LH and FSH into the circulation. These in turn stimulate receptors on testicular Leydig and Sertoli cells, respectively, to promote steroidogenesis and spermatogenesis. Both Leydig and(More)
BACKGROUND Galacto-oligosaccharides (GOS) are prebiotics added to commercial milk formula of infants and mothers. In recent years, cases of allergy related to GOS in atopic children have been reported in the South East Asian region. CASE PRESENTATIONS We describe a series of pregnant (n = 4) and lactating mothers (n = 2) who developed anaphylactic(More)
The peptide hormone INSL3 is uniquely produced by the fetal testis to promote the transabdominal phase of testicular descent. Because it is fetal sex specific, and is present in only very low amounts in the maternal circulation, INSL3 acts as an ideal biomarker with which to monitor the movement of fetal hormones within the pregnant uterus of a polytocous(More)
Background. Intravenous alemtuzumab and fludarabine are effective in combination for the treatment of chronic lymphocytic leukemia (CLL), but require hospital visits for intravenous injection. We performed a pilot study to assess the safety and efficacy of outpatient-based oral fludarabine with subcutaneous alemtuzumab (OFSA) for the treatment of(More)
