<P>With increasing demands toward device miniaturization, Pb-free magnetoelectric laminates (MELs) with a small lateral dimension of similar to 3 x 3 mm(2) have been synthesized by the tape-casting method. The MELs are composed of alternating layers of magnetostrictive NiFe2O4 and piezoelectric BaTiO3 with a uniform single layer thickness of t = 50 and 15 gm, respectively. Both laminates exhibit much larger longitudinal ME voltage coefficient alpha(E33) than the transverse ME voltage coefficient alpha(E31) at both off-resonant and resonant frequencies, which is attributed to the preferential easy-plane alignment of the magnetic moments. Furthermore, enhancement in alpha(E33) by more than 5 times has been achieved upon decreasing t from 50 to 15 mu m in both resonance and off-resonance conditions. The enhanced alpha(E33) values indicate that nearly ideal interface coupling between the ferromagnetic and piezoelectric layers is realized in the miniaturized, thinner MEL, pointing to practical application potential towards developing mass-produced, low-cost ME devices.

<P>We prepared a bone plate enabled with the local, sustained release of alendronate, which is a drug known to inhibit osteoclast-mediated bone resorption and also expedite the bone-remodeling activity of osteoblasts. For this, we coated a bone plate already in clinical use (PLT-1031, Inion, Finland) with a blend of alendronate and a biocompatible polymer, azidobenzoic acid-modified chitosan (i.e., Az-CH) photo-crosslinked by UV irradiation. As we performed the in vitro drug release study, the drug was released from the coating at an average rate of 4.03 mu g/day for 63 days in a sustained manner. To examine the effect on bone regeneration, the plate was fixed on an 8 mm cranial critical size defect in living rats and the newly formed bone volume was quantitatively evaluated by micro-computed tomography (micro-CT) at scheduled times over 8 weeks. At week 8, the group implanted with the plate enabled with sustained delivery of alendronate showed a significantly higher volume of newly formed bone (52.78 +/- 6.84%) than the groups implanted with the plates without drug (23.6 +/- 3.81%) (p < 0.05). The plate enabled with alendronate delivery also exhibited good biocompatibility on H&E staining, which was comparable to the Inion plate already in clinical use. Therefore, we suggest that a bone plate enabled with local, sustained delivery of alendronate can be a promising system with the combined functionality of bone fixation and its expedited repair.

Final R = 0.045 for 1164 observed reflections. In the β-lactam system, the amide group is almost planar with bond distances 1.334(4) and 1.220 (4) Å for C-N and C=O, respectively. These structural results are consistent with those of other biologically inactive β-lactams.

Twelve multiparous Holstein dairy cows in mid-lactation were selected for a replicated 4×4 Latin square design with a 2 ×2 factorial arrangement to investigate the effects of corn and soybean meal (SBM) types on rumen fermentation, N metabolism and lactation performance in dairy cows. Two types of corn (dry ground [DGC] and steam-flaked corn [SFC]) and two types of SBM (solvent-extracted and heat-treated SBM) with different ruminal degradation rates and extents were used to formulate four diets with the same basal ingredients. Each period lasted for 21 days, including 14 d for adaptation and 7 d for sample collection. Cows receiving SFC had a lower dry matter (DM) and total N intake than those fed DGC. However, the milk yield and milk protein yield were not influenced by the corn type, resulting in higher feed and N utilization efficiency in SFC-fed cows than those receiving DGC. Ruminal acetate concentrations was greater and total volatile fatty acids concentrations tended to be greater for cows receiving DGC relative to cows fed SFC, but milk fat content was not influenced by corn type. The SFC-fed cows had lower ruminal ammonia-N, less urea N in their blood and milk, and lower fecal N excretion than those on DGC. Compared with solvent-extracted SBM-fed cows, cows receiving heat-treated SBM had lower microbial protein yield in the rumen, but similar total tract apparent nutrient digestibility, N metabolism measurements, and productivity. Excessive supply of metabolizable protein in all diets may have caused the lack of difference in lactation performance between SBM types. Results of the present study indicated that increasing the energy degradability in the rumen could improve feed efficiency, and reduce environmental pollution.

Hanwoo is an indigenous Korean beef cattle breed, and it shared an ancestor with Yanbian cattle that are found in the Northeast provinces in China until the last century. During recent decades, those cattle breeds experienced different selection pressures. Here, we present genome-wide copy number variations (CNVs) by comparing Hanwoo and Yanbian cattle sequencing data. We used ~3.12 and ~3.07 billion sequence reads from Hanwoo and Yanbian cattle, respectively. A total of 901 putative CNV regions (CNVRs) were identified throughout the genome, representing 5,513,340bp. This is a smaller number than has been reported in previous studies, indicating that Hanwoo are genetically close to Yanbian cattle. Of the CNVRs, 53.2% and 46.8% were found to be gains and losses in Hanwoo. Potential functional roles of each CNVR were assessed by annotating all CNVRs and gene ontology (GO) enrichment analysis. We found that 278 CNVRs overlapped with cattle gene-sets (genic-CNVRs) that could be promising candidates to account for economically important traits in cattle. The enrichment analysis indicated that genes were significantly over-represented in GO terms, including developmental process, multicellular organismal process, reproduction, and response to stimulus. These results provide a valuable genomic resource for determining how CNVs are associated with cattle traits.
