Effect of probiotics or high incubation temperature on gene expression and cell organization of the small intestine and yolk sac of chicks
The small intestine and yolk sac (YS) are important organs for nutrient absorption and innate immunity in chickens during the post-hatch or prehatch periods. These organs share a similar structure of epithelial cell-lined villi with tight junctions between adjacent cells. Probiotics have been …

STRUCTURAL AND FUNCTIONAL CHARACTERIZATION OF ARCHAEAL BOX H/ACA RIBONUCLEOPROTEIN INVOLVED IN RIBOSOMAL RNA PSEUDOURIDYLATION
… in sRNP-mediated rRNA pseudouridylation. Certain Ys in rRNAs are evolutionarily conserved from Bacteria to human. Among those, two Ys are present in helix 69 of rRNA and one in helix 90. We successfully deleted Cbf5 in Haloferax volcanii, a haloarchaeon, and showed that the deleted strain was …

Effects of high shear deformation from equal channel angular pressing-conform and post thermal mechanical processing on the microstructural and mechanical properties of titanium alloys
… processing and properties of titanium alloys subject to equal channel angular pressing-conform (ECAP-C) and post thermal mechanical processing (TMP). The ECAP-C process uses high-shear deformation to refine the microstructure with the goal of producing an ultrafine grain material with …

Solidification, microstructure and mechanical properties of mg-nd-gd-zn-zr cast magnesium alloy with yttrium, erbium and samarium additions
… experience tremendous progress if magnesium alloys become an integral part of their production unit mainly because of their light weight. The main limitation to progress in this direction is paucity in the mechanical properties of magnesium alloys. Rare earth elements have been used as alloying …

Informing U.S. Caribbean fisheries management through simulation modeling: a case of length-based mortality estimation models
… sample sizes (n), and sampling program length (Ys) on total mortality rate estimates (Z). Given the scenarios investigated, the Beverton-Holt model produced consistently biased, but more stable results when n was low, variation was high for both growth and recruitment, and sampling began after …

Effect of Processing Path on Microstructure and Mechanical Properties of a Low Carbon, Low Alloy Advanced High Strength Steel
… A significant increase in yield strength, YS, (1010 MPa) and ultimate tensile strength, UTS, (1109 MPa) was noted in water-quenched condition in comparison with the YS of 426 MPa and UTS of 612 MPa in air-cooled condition. The total elongation (TE) in air-cooled and water-quenched …

Characterizing PIAS1 Function During Embryogenesis and Lung Cancer Progression
… field. We used mice (Mus musculus) as our model system for studying the function of Pias1 by global inactivation of this gene in mammals to discover tissues and biological processes affected by the loss of Pias1. We found that, in agreement with previous reports, inactivation of Pias1 results in …

Investigation of the mechanism of radical propagation in E. coli ribonucleotide reductase by site-specific incorporation of unnatural amino acids
… respectively, and a series of fluorotyrosines (FnYs, n=2, 3, 4), which we have established as probes for proton-coupled electron transfer reactions and incorporated into 12, we propose a mechanism for radical transfer in RNR. We show that binding of substrate and effector are essential for control …
