The effects of Ca and Ba substitutions for Sr on the structure properties ${\mathrm{Sr}}_{2}$${\mathrm{IrO}}_{4}$ were studied. Increase in Ir-O(2)-Ir bond angle ${\mathrm{IrO}}_{2}$ plane was found after Sr. However, Ir-O(2) distance is to be unchanged by substitution, while it decreases substitution. Regardless these structural changes, magnetic transition temperature at 240 K unchanged. Semiconductive behavior resistivity all compounds with increase activation energy above 200 K. Both...
To investigate the pathogenesis of accelerated bone formation in estrogen deficiency, diffusion chambers containing osteoblast-like cells isolated from newborn rat calvariae were transplanted into peritoneal cavity sham-operated (sham), ovariectomized (OVX) rats, and OVX rats with supplement 17 beta-estradiol (OVX + E2). Bone was more than that sham E2 rats. Osteoblast-like cultured sera exhibited higher levels DNA content culture wells, alkaline phosphatase activity, messenger RNA...
Expression of estrogen receptor (ER) was studied in MC3T3-E1 cells (mouse osteoblastic cell line), HOS TE85 (human osteosarcoma and primary derived from mouse calvaria with immunohistochemical techniques. The staining ER readily detectable cells, by using a monoclonal anti-ER antibody that recognizes the DNA binding domain ER. immunoreactivity distributed cytoplasm as well nuclei. 17 beta-Estradiol (10(-8) M) did not alter this pattern. expression confirmed Northern blot analysis rat cDNA...
Abstract Enzymatic hydrolysis of poly(butylene succinate) (PBS) and succinate‐ co ‐ L ‐lactate) (PBSL) has been studied by using a lipase originated from Pseudomonas cepacia . It found that the drawn fibers PBSL are readily hydrolyzed action lipase, while those PBS undergo little enzymatic hydrolysis. Since polymer films under same conditions, should depend not only on crystallinity but also molecular orientation. The weight samples gradually decreases with incubation time, because...
Abstract Polycrystalline CaMoO3 was prepared by a new method making use of the oxygen stability range, and revealed to have an orthorhombic lattice (a=5.448Å, b=7.776Å, c=5.582Å), metallic conduction Pauli paramagnetism. The results indicate that 4d2 electrons Mo4+ are delocalized in as same those BaMoO3 SrMoO3.
Abstract The rock salt arrangement between Mn and Mo or Ta was found in new compounds (BaLa) (MnMo)O6 (SrLa) (MnTa)O6. fluorescent X-ray Kβ shift from located those of MnO (MnTa)O6 obeyed the Curie–Weiss law above room temperature, while showed a ferrimagnetism with Tc=120 K. valency pair (Mn2+, Mo5+) verified.
We elucidate the magnetic phases and superconducting (SC) transition temperatures (T c) in Sr2VFeAsO3-δ (21113V), an iron-based superconductor with a thick-blocking layer fabricated from perovskite-related metal oxide. At low < 37.1 K), 21113V exhibited SC phase range 0.031 ⩽ δ 0.145 antiferromagnetic (AFM) iron sublattice 0.267 0.664. Mixed-valent vanadium dominant AFM 0.088, partial ferrimagnetic (Ferri.) 0.124 The Ferri. was most at value of 0.267, showing Fe T 20 K. Increasing...
X-ray photoelectron diffraction (XPD) patterns of In 3d core levels have been measured for the Si(001)-(4×3)-In surface. An R factor analysis with single-scattering and multiple-scattering simulations XPD was performed three structural models proposed so far. Only model by surface [Appl. Surf. Sci.123/124, 104 (1998)] appeared to give a reasonably small when geometric parameters were modified from original ones.

Abstract Ordered perovskites,(LaSr) (Mn2+W5+)O6 and (LaSr) (Mg2+W5+)O6, were newly prepared. The lattice constants,the electrical conductivities the magnetic moments studied. results indicate that 3d5 electrons in Mn2+ are almost localized interaction between W5+ is fairly weak this compound.
Chain-extended poly(butylene succinate) (PBS-e) and succinate/adipate) (PBSA-e) as well high polymers of succinate-co-carbonate) (PBSC) succinate-co-ε-hydroxycaproate) (PBSCL) were melt-spun into mono-filament fibers by the on-line spinning drawing technique. The mechanical properties degradability these totally compared in reference to those homopolymer (PBS) succinate-co-L-lactate) (PBSL).

Abstract The magnetic properties of 8H-type hexagonal-type Ba(Na1/4Ru3/4)O3 having a 2D geometry Ru5+(t2g3) ions were studied by magnetic-susceptibility measurements in the temperature range 5 K &lt; T 700 K. In this structure, face-shared RuO6 octahedra form (Ru2O9)8− clusters with array, which are sandwiched layers NaO6 and corner-shared octahedra. data show an antiferromagnetism-like behavior, could be well fitted to Curie-Weiss law above 520 μeff = 3.74 μB θ −1330 At lower 262 K, it...
ABSTRACT A saponin-enriched soybean extract was tested for agonistic activities against a series of nuclear receptors including peroxisome proliferator-activated (PPARs) and cholesterol metabolism-related, retinoid-related, hormone-related detoxification-related as well the transcription factor Nrf-2 to elucidate its mechanism action. Reporter gene assays were used measure Nrf-2. The found increase PPARα, PPARδ PPARγ, liver X receptor (LXR)α LXRβ, estrogen (ER)α dose-dependently. At 500...
