\n\nResult(s): No differences in cleavage or blastocyst formation were found in different groups in experiment check details 1, 2, or 3. Embryos cultured singly had fewer ICM and TE cells than those cultured in groups. Embryos cultured singly in 0.5 mu L had fewer TE cells than those in 10 mu L, but had insignificant difference in the ICM. Duo culture in 0.5-2 mu L appeared to give the same results as group culture in 10-mu L drops.\n\nConclusion(s): Group culture is preferred when using sequential media. Beneficial effects cannot be mimicked by volume reduction
in single-embryo culture. (Fertil Steril (R) 2011;95:1435-9. (C)2011 by American Society for Rigosertib Reproductive Medicine.)”
“Background. Atypical haemolytic uraemic syndrome
(aHUS) is associated with dysfunction of the alternative pathway of complement. Disease activity subsides as renal failure progresses but recurs upon renal transplantation, indicating that viable renal tissue contributes to disease activity. We present evidence of cerebrovascular occlusive disease indicating that vascular injury may occur in the absence of kidneys.\n\nA currently 12-year-old girl developed renal failure at the age of 20 months. She underwent bilateral nephrectomy and renal transplantation but lost the transplant due to recurrences. She was on haemodialysis for 7 years. At 10 years of age she developed a transient ischaemic attack. Imaging, genetic investigation and mutation characterization were performed.\n\nImaging demonstrated occlusion and stenosis of the carotid arteries. Two complement mutations, a novel mutation in factor B and a previously described mutation in factor I, and the H3-factor H haplotype, were identified. The factor B mutation, L433S, did not induce www.selleckchem.com/products/lxh254.html excessive complement activation in vitro. Measurement
of C3 degradation products indicated ongoing complement activation. In spite of the patient being anephric, treatment was initiated with eculizumab, a humanized anti-C5 antibody that blocks terminal complement activation. She underwent a successful kidney transplant 9 months later and has not developed a recurrence or progression of vascular stenosis 1 year later.\n\nThe course of disease in this patient with aHUS suggests that complement-mediated vascular injury may occur in the total absence of renal tissue and overt recurrences. To our knowledge, this is the first description of eculizumab treatment in an anephric aHUS patient.”
