| 1 | Microstructural dependence of magnetic and magnetostrictive properties in Fe-19 at% Ga显示文摘A combination study of magnetic and magnetostrictive properties in directionally cast(DC)(un-annealed)and differently heat-treated Fe-19 at%Ga samples was carried out at room temperature.Slow cooling leads to an increase in the occupation of[200]easy magnetic axis.However,structural ordering of Ga atoms into a metastable D03 phase decreases the saturation magnetostriction(λs)and saturation magnetization(Ms),while increases coercivity(Hc).Water quenching suppresses the formation of stable fee ordered phase(L12)and largely preserves disordered bcc single-phase(A2)structure down to room temperature,leading to enhanced magnetostriction and magnetization.Slow cooling promotes the ordering of metastable bcc ordered phase(D03).Magnetic force microscopy(MFM)study exhibits that the water-quenched(WQ)sample consists of a well-aligned stripe domain structure,while irregular maze-like domain structure is observed in furnace-cooled(FC)sample.The results confirm that in addition to an inhibitory effect of D03 ordering on magnetic domain wall motions,irregular magnetic domains also contribute to decrease in magnetic and magnetostrictive properties of FC sample. | Aliakbar Emdadi Syamak Hossein Nedjad Habib Badri Ghavifekr Majid Kavanlouei Faezeh Alijan Farzad Lahiji Vahid Ramezankhani | 2020 | Rare Metals2020，39，4： | 1 |

| 4 | Brain-derived neurotrophic factor in patients with advanced age-related macular degeneration显示文摘AIM: To investigate the serum level of the brain-derived neurotrophic factor(BDNF) in age-related macular degeneration(AMD) and healthy control subjects. The disruption in the tight balance of neuroinflammatory and neuroprotective processes in an immune-privileged site like retina is proposed to contribute to the pathogenesis of AMD. One of the main neuroprotective mediators in the central nervous system is BDNF with its serum level notably affected in several neurodegenerative disorders.·METHODS: Thirty-six patients with AMD and 36 agematched controls were enrolled in this study. The serum level of BDNF was measured using the enzyme-linked immunosorbent assay method. Results were analyzed to compare case and control values. Comparisons were also made between the BDNF level of wetvs dry-AMD,and male vs female patients and controls. Analysis of variance(ANOVA) and Student's t-test were employed to analyze the data.·RESULTS: The mean BDNF levels in AMD group were significantly higher than the control group. Furthermore,our analysis revealed greater BDNF values in all AMDsubgroups compared to controls(P =0.004, 0.005, 0.001 and 0.02 for male wet-AMD, male dry-AMD, female wetAMD and female dry-AMD vs controls, respectively). The BDNF level however did not vary between wet- and dryAMD patients(P =0.74). While within-group comparisons in males and females of AMD and control groups did not show any difference in BDNF(P =0.16, 0.64 and 0.85 for wet-AMD, dry-AMD and control groups, respectively),between-group data showed a higher mean BDNF in both male and female AMD subjects than their peer controls.·CONCLUSION: This study demonstrated that the serum BDNF level is different in patients with AMD as compared to subjects without AMD. Future attempts should be done to unravel beneficial or deleterious effect of this neurotrophin in the pathogenesis of AMD. | Mehrdad Afarid Mohammad Torabi-Nami Alijan Nemati Amir Khosravi Mahyar Malekzadeh | 2015 | International Journal of Ophthalmology(English edition)2015，8，5： | 0 |
