93 at 14 K and similar to 0.77 at 290 K. Moreover, the insertions of 1 nm thick Co2Fe(Al0.5Si0.5) layers at Co50Fe50/Ag interfaces effectively improved the output of CPP-GMR. Thus, Ag is considered to be a suitable spacer material for the Co2Fe(Al0.5Si0.5) Heusler alloy with a good band matching. (C) 2011 American Institute of Physics. [doi:10.1063/1.3554206]“
“Recurrence is a key characteristic in the development of epilepsy. It remains unclear whether seizure recurrence is sensitive to postseizure stress. Here, tonic-clonic seizures were induced with
a convulsive dose of pentylenetetrazole (PTZ), and acute seizure recurrence was evoked with a subconvulsive dose of the drug. We found that stress inhibited seizure recurrence when applied 30 minutes or 2 hours, but not 4 hours, after the tonic-clonic seizure. NCT-501 clinical trial The time-dependent
anti-recurrence effect of stress was mimicked by the stress hormone corticosterone and blocked by co-administration of mineralocorticoid and glucocorticoid receptor antagonists. Furthermore, in a PTZ-induced epileptic kindling model, corticosterone administered 30 minutes after each seizure decreased the extent Semaxanib of seizures both during the kindling establishment and in the following challenge test. These results provide novel insights into both the mechanisms of and therapeutic strategies for epilepsy. (C) 2010 Elsevier Inc. All rights reserved.”
“Background and aims: Women with gestational diabetes mellitus (GDM) have an enhanced cardiovascular risk factor profile at 3-months postpartum and an elevated risk of future cardiovascular disease, as compared to their peers. Recently, it has emerged that even mild dysglycemia on antepartum oral glucose tolerance test (OGTT) predicts an increased risk of future cardiovascular disease, although it is not known whether there exists an identifiable high-risk subgroup within this patient population. Since gestational impaired glucose tolerance (GIGT) due to isolated hyperglycemia
at 1-h during the OGTT (1-h GIGT) bears metabolic similarity to GDM, we hypothesized AG-881 research buy that, like GDM, 1-h GIGT may predict a high-risk postpartum cardiovascular phenotype.
Methods and results: In this prospective cohort study, 485 women underwent antepartum OGTT, followed by cardiovascular risk factor assessment at 3-months postpartum. The antepartum OGTT identified 4 gestational glucose tolerance groups: GDM (n = 137); 1-h GIGT (n = 39); GIGT at 2- or 3-h (2/3-h GIGT)(n = 50); and normal glucose tolerance (NGT)(n = 259). After adjustment for age, ethnicity, breastfeeding and waist circumference, mean levels of the following cardiovascular risk factors progressively increased from NGT to 2/3-h GIGT to 1-h GIGT to GDM: LDL cholesterol (p = 0.0026); total cholesterol: HDL (p = 0.0030); apolipoprotein B (p = 0.004); apolipoprotein B: apolipoprotein A1 (p = 0.026); leptin (p = 0.018); and C-reactive protein (p = 0.011).
