With increasing t(AFM), all these quantities undergo nonmonotonic variations, except for the monotonic change in the exchange field. The maximal values of the coercivity, its relative change, and the rotational hysteresis loss are almost located at the same t(AFM) of 3.8 nm. The maximal values of the relative change in the exchange field and of the hysteretic effect of the angular dependence are located at 2.5 and 3.0 nm, respectively. The rotational hysteresis loss and the hysteretic behavior of the angular dependence of the exchange bias have different characteristics. The variations

of all physical quantities with t(AFM) can be ascribed to the irreversible reversal of the antiferromagnet spins, which are governed by the Arrhenius-Neel law, except for that of the rotational hysteresis find more loss.”
“This study determined whether morphokinetic variables between aneuploid HDAC inhibition and euploid embryos differ as a potential aid to select euploid embryos for transfer. Following insemination, EmbryoScope

time-lapse images from 98 blastocysts were collected and analysed blinded to ploidy. The morphokinetic variables were retrospectively compared with ploidy, which was determined following trophectoderm biopsy and analysis by array comparative genomic hybridization or single-nucleotide polymorphic array. Multiple aneuploid embryos were delayed at the initiation of compaction (t(SC); median 85.1 hours post insemination (hpi); P = 0.02) and the time to reach full blastocyst stage (t(B); median 110.9 hpi, P = 0.01) compared with euploid embryos (t(SC) median 79.7 hpi, t(B) median 105.9 hpi). Embryos having single or multiple aneuploidy (median 103.4 hpi, P = 0.004 and 101.9 hpi, P = 0.006, respectively) had delayed initiation of blastulation compared with euploid embryos PF-6463922 (median 95.1 hpi). No significant differences were observed in first or second cell-cycle length, synchrony of the second or third cell cycles, duration of blastulation, multinucleation at the 2-cell stage and irregular division patterns between euploid

and aneuploid embryos. This non-invasive model for ploidy classification may be used to avoid selecting embryos with high risk of aneuploidy while selecting those with reduced risk. (C) 2013, Reproductive Healthcare Ltd. Published by Elsevier Ltd. All rights reserved.”
“Introduction Paraneoplastic neurological disorders are rare complications of breast carcinoma. Lambert-Eaton Myasthenic Syndrome (LEMS) is most commonly associated with small cell lung cancer. However, a combination of LEMS and subacute cerebellar degeneration as paraneoplastic syndromes is extremely rare, and has never been described in association with breast cancer.

Case We report for the first time an unusual association of LEMS and paraneoplastic subacute cerebellar degeneration with breast carcinoma.
