magnetometric and ferromagnetic resonance(mFR)measurements have been performed on the polycrystalline multilayered structure,[Gd(7.5 nm)/Co(3 nm)]*** temperature dependence of magnetization of the sample suggests a compensation temperature Tcomp in the region of 240 K,implying that the Co and Gd layers are antiferromagnetically *** FmR curves are strongly temperature dependent,particularly in the vicinity of Tcomp.

BACKGROUND: monochorionic twin pregnancies complicated by severe twin to twin transfusion syndrome at midgestation can be treated by either serial amnioreduction(removal of large volumes of amniotic fluid) or selective fetoscopic laser coagulation of the communicating vessels on the chorionic plate. We conducted a randomized trial to compare the efficacy and safety of these two treatments. mETHODS: Pregnant women with severe twin to twin transfusion syndrome before 26 weeks of gestation were randomly assigned to laser therapy or amnioreduction. We assessed perinatal survival of at least one twin (a prespecified primary outcome),survival of at least one twin at six months of age, and survival without neurologic complications at six months of age on the basis of the number of pregnancies or the number of fetuses or infants, as appropriate. RESULTS:The study was concluded early, after 72 women had been assigned to the laser group and 70 to the amnioreduction group, because a planned interim analysis demonstrated a significant benefit in the laser group. As compared with the amnioreduction group, the laser group had a higher likelihood of the survival of at least one twin to 28 days of age (76 percent vs. 56 percent; relative risk of the death of both fetuses, 0.63; 95 percent confidence interval, 0.25to 0.93; P=0.009) and 6 months of age (P=0.002). Infants in the laser group also had a lower incidence of cystic periventricular leukomalacia (6 percent vs. 14 percent,P=0.02) and were more likely to be free of neurologic complications at six months of age (52 percent vs. 31 percent, P=0.003). CONCLUSIONS: Endoscopic laser coagulation of anastomoses is a more effective first linetreatment than serial amnioreduction for severe twin totwin transfusion syndrome diagnosed before 26 weeks of gestation.

The cells of origin of neurogenic heterotopic ossifications(NHOs), which develop frequently in the periarticular muscles following spinal cord injuries(SCIs) and traumatic brain injuries, remain unclear because skeletal muscle harbors two progenitor cell populations: satellite cells(SCs), which are myogenic, and fibroadipogenic progenitors(FAPs), which are mesenchymal. Lineage-tracing experiments using the Cre recombinase/Lox P system were performed in two mouse strains with the fluorescent protein Zs Green specifically expressed in either SCs or FAPs in skeletal muscles under the control of the Pax7 or Prrx1 gene promoter, respectively. These experiments demonstrate that following muscle injury, SCI causes the upregulation of PDGFRα expression on FAPs but not SCs and the failure of SCs to regenerate myofibers in the injured muscle, with reduced apoptosis and continued proliferation of muscle resident FAPs enabling their osteogenic differentiation into NHOs. No cells expressing Zs Green under the Prrx1 promoter were detected in the blood after injury, suggesting that the cells of origin of NHOs are locally derived from the injured muscle. We validated these findings using human NHO biopsies. PDGFRα+mesenchymal cells isolated from the muscle surrounding NHO biopsies could develop ectopic human bones when transplanted into immunocompromised mice, whereas CD56+myogenic cells had a much lower potential. Therefore, NHO is a pathology of the injured muscle in which SCI reprograms FAPs to undergo uncontrolled proliferation and differentiation into osteoblasts.
