    Mu opioid receptor-like sequences are present throughout vertebrate evolution (1996)

    Notes: Abstract The sequence of the mu opioid receptor is highly conserved among human, rat, and mouse. In order to gain insights into the evolution of the mu opioid receptor, polymerase chain reaction (PCR) was used to screen genomic DNA from a number of different species using degenerate oligonucleotides which recognize a highly conserved region. DNA was assayed from representative species of both the protostome and deuterostome branches of the metazoan phylogenetic tree. Mu opioid receptor-like sequences were found in all vertebrate species that were analyzed. These species included bovine, chicken, bullfrog, striped bass, thresher shark, and Pacific hagfish. However, no mu opioid receptor-like sequences were detected from protostomes or from any invertebrates. The PCR results demonstrate that the region of the mu opioid receptor gene between the first intracellular loop and the third transmembrane domain (TM3) has been highly conserved during evolution and that mu opioid receptor-like sequences are present in the earliest stages of vertebrate evolution. Additional opioid receptor-like sequence was obtained from mRNA isolated from Pacific hagfish brain using rapid amplification of cDNA ends (RACE). The sequence of the Pacific hagfish was most homologous with the human mu opioid receptor (72% at the amino acid level between intracellular loop 1 and transmembrane domain 6) although over the same region high homology was also observed with the delta opioid receptor (69%), the kappa receptor (63%), and opioid receptor-like (ORLI) (59%). The hag-fish sequence showed low conservation with the mammalian opioid receptors in the first and second extracellular loops but high conservation in the transmembrane and intracellular domains.

    Notes: Yttrium oxide hydroxide nitrate (Y4O(OH)9NO3), which was prepared by polyvinyl alcoholassistedhydrothermal method from the Y(NO3)3 and KOH starting solution, was characterized by XRDand FE-SEM. The results revealed that pH value of the starting solution is an important factor whichdetermines the morphology and size of the products. The obtained products varied from lamina microprismsto circular nanorods when the pH value increased from 7.0 to 8.0. In the high pH value above 8.0,the size of nanorods decreased with increasing pH value. A primary mechanism was proposed to explainthe evolution of morphology and size of Y4O(OH)9NO3 products prepared under various pH values

    Notes: XRD, SEM, bulk density and dielectric properties measurements were used to investigate theeffect of TiO2 nanopowder substitution for conventional TiO2 micro-powder on the sintering and electricproperties of PZT ceramics. Results revealed that the sintering temperature of dense Pb(Zr0.53Ti0.47)O3ceramics was lowered about 50°C ~ 100°C when 20% and 40% of conventional TiO2 micro-powder wassubstituted by TiO2 nanopowder. The electric properties were kept or even enhanced in the PZT ceramicsadopted the TiO2 nanopowder

    Notes: Yttrium oxide hydroxide nitrate nanorods were prepared via a facile hydrothermal methodusing PEG-6000 as template in Y(NO3)3 and KOH reactant system. The effect of hydrothermal treatmenttime on the crystallite structure, the crystallite shape and size was investigated by XRD and FE-SEMmeasurements. XRD results showed that the main phase of the as-prepared product was Y4O(OH)9NO3crystal of monoclinic phase. FE-SEM images displayed that the size of the nanorods grows large withincreasing time from 5h to 24h. Furthermore, no shape change was found, demonstrating that the asgrown nanorods are stable when the reaction time increased from 1h to 24 h. Dissolution recrystallizationprocess was proposed to explain the growth process of Y4O(OH)9NO3 nanorods

    Notes: The filling of multi-walled carbon nanotubes with metallic silver nanowires via wetchemistry method was investigated. The carbon nanotubes were filled with long continuous silvernanowires. The carbon nanotubes were almost opened and cut after being treated with concentratednitric acid. Silver nitrate solution filled carbon nanotubes by capillarity. Carbon nanotubes werefilled with silver nanowires after calcinations by hydrogen. The diameters of silver nanowires werein the range of 20-40 nm, and lengths of 100 nm - 10 μm. We studied the micromorphology of thesilver nanowires filled in carbon nanotubes by transmission electron microscopy (TEM) and X-raydiffraction (XRD). Based on the experimental results, a formation mechanism of the Agnanowire-filled carbon nanotubes was proposed

    Notes: Surface modification was conducted on the basic magnesium sulfate whiskers (MSW) using sodium stearate. The modification performance was evaluated by comparing the activation index, oil absorption value, rest angle, and dispersibility in polypropylene (PP) resin prior to and after treatment. It was found that the surface properties of the whiskers were improved by sodium stearate modification. In particular, the improvement in the dispersibility in PP was significant. Surface characterization was conducted using scanning electron microscopy (SEM), thermogravimetric-differential scanning calorimetry (TG-DSC) and fourier transform infrared spectroscopy (FTIR) for the raw and modified whiskers. The results indicated the co-existence of both chemical and physical adsorptions of sodium stearate on the surfaces of MSW

Based on the experimental results, a formationmechanism of the Ag nanowire-filled carbon nanotubes was proposed. And the microwavepermittivity of the carbon nanotubes filled with metallic silver nanowires was measured in thefrequency range from 2 GHz to 18 GHz. The loss tangent of the carbon nanotubes filled withmetallic silver nanowires is high. So the carbon nanotubes filled with metallic silver nanowireswould be a good candidate for microwave absorbent

    Notes: Carbon fiber reinforced concrete (CFRC) structures exhibit both strain sensibility andtemperature sensibility, which are coupled with each other when used in traffic or health monitoringfor concrete structures. This coupling property results in inaccurateness of measured deformation.In this paper Four-probe Difference Method is used to detach the above two effects according toloaded conditions of structures and different characteristics of the two effects. The theoretical andexperimental results indicate that the method is feasible and effective
