    Notes: We investigated whether human β2 adrenoceptor (β2AR) gene polymorphisms are associated with the pressor response to laryngoscopy and tracheal intubation. Ninety-two patients undergoing elective surgery under general anaesthesia were enrolled into this study. Arterial systolic pressure, heart rate and rate pressure product were measured before induction of anaesthesia and 1 min following laryngoscopy and tracheal intubation. Genomic DNA was then used to identify the β2AR-16 and β2AR-27 genes using an allele-specific polymerase chain reaction method. Using multiple linear regression models, controlling for age, sex, weight, baseline blood pressure, heart rate and rate pressure product, we found that patients who possessed the glutamic acid homozygote of β2AR-27 produced significantly greater changes in mean arterial pressure and rate pressure products than patients with the glutamine homozygote of β2AR-27 (β coefficient for mean blood pressure = 11.81, β coefficient for pulse−pressure product = 8.76, both p-values = 0.023). These findings suggest that genetic variability in the human β2AR gene polymorphisms may be associated with the pressor response to laryngoscopy and tracheal intubation.

    Various methods to determine the gonadal development and spawning season of the purplish Washington clam, Saxidomus purpuratus (Sowerby) (2005)

    Notes: The monthly variation in reproductive cycle, condition factor (fatness), gonad index (GI), ovarian egg diameter and biochemical composition [RNA, DNA content and their ratio RNA/DNA (R/D)] were compared to determine the spawning season of the purplish Washington clam, Saxidomus purpuratus, collected from the west sea of Taean, Korea. All these factors were correlated to the spawning season from May to October. Monthly variation and concentration of the R/D ratio especially represented indicative information about the processes of gonad development and spawning patterns. The increases in R/D ratio in the ovaries corresponded with increases in ovarian egg diameters and the GI during the spawning season. The peak of R/D and RNA content in females was a good indicator of sexual maturation and the DNA content in males. During winter between November and January, the value of fatness, GI, egg size, RNA and DNA content were lower than in other seasons, indicating depletion of energy reserves and lower metabolic demands because of colder temperatures.

    Pax-7 Immunoreactivity in the Post-natal Chicken Central Nervous System (2003)

    Notes: In this immunocytochemical study on the constitutive expression of Pax-7 protein in the postnatal chicken brain, Pax-7 showed region and cell type specific expression. In the optic tectum, only cells in grey matter showed positive immunoreactivities (IRs), whereas those in the white matters did not show any IRs. In thalamic nuclei and several pontine nuclei, we also localized Pax-7 positive IRs. On the contrary, in the cerebellum, Pax-7 was mainly localized within the Bergmann glia, whereas Purkinje cells did not show any IRs. In double immunolabelling studies, most of the Pax-7 IRs did not originate from neuroglial cells such as oligodendrocytes, microglia or astrocytes, but from neurons, with the exception of Bergmann glia in the cerebellum. The presence of Pax-7 IRs in the adult chicken brain could suggest that Pax-7 might play a role in maintaining normal physiological function in some postnatal chicken brain cells.

    The magnetic properties of Fe-based amorphous ribbons coated with various oxides using the sol–gel process (1997)

    Notes: Abstract The metal oxides MgO, BaO, Al2O3, SiO2, MgO–Al2O3, CaO–Al2O3, SrO–Al2O3, BaO–Al2O3 and MgO–SiO2 have been coated onto ribbons of the Fe-based amorphous alloy Metglas 2605S3A using a sol–gel process. The effects of the surface coating on the magnetic properties of the alloy are investigated. The d.c. hysteresis loop for ribbons coated with MgO and MgO–Al2O3 is more square shaped than that for the uncoated ribbon. For ribbons coated with BaO, SrO–Al2O3 and BaO–Al2O3 it is more inclined than for the uncoated ribbon. Significant differences in the frequency dependence of the effective permeability are observed that depend on the nature of the coated oxides. The core loss is also affected by the coating. These results may be explained in terms of a stress induced by the coating and the modification of the domain structure via elastic and/or magnetoelastic interactions. It is thought from the magnetoelastic interactions that the MgO and MgO–Al2O3 coatings induce tensile stresses whilst those of BaO, SrO–Al2O3 and BaO–Al2O3 induce compressive stresses.

    Start-up and operation of anaerobic biofilters with packing alternatives (1989)

    Notes: Abstract Four types of anaerobic upflow biofilters: non-packed (NP-AUBF), two-stage (2S-AUBF), multi-stage (MS-AUBF) and fully-packed (FP-AUBF), were tested for their start-up and operational performance characteristics. The volume of each filter was 12.1 dm3 (10 cm I.D.x155 cm in height). Stepwise seeding was conducted and the effect on the reduction of COD and gas production was monitored. When each reactor was loaded with 2 and 4 kg COD/m3-day of synthetic waste simulating alcohol production plant, 2S-, MS-, FP-AUBF had treatment efficiencies of 89–93%, while NP-AUBF showed efficiencies lower than 50%. As a conclusion, 2S- or MS-AUBF can be used as efficiently as FP-AUBF, while the amount of packings in the former is half that in FP-AUBF.

    Adsorption of oxygen on the paramagnetic defect centers in aluminophosphate molecular sieves (1997)

    Notes: Abstract Temperature-programmed desorption (TPD) and electron spin resonance (ESR) techniques have been employed to investigate the oxygen adsorbed on the paramagnetic defect centers in dehydroxylated AlPO4-20, AlPO4-11, AlPO4-5, and VPI-5 molecular sieves. Two different adsorption sites are observed for the small-pore AlPO4-20, where oxygen is entrapped within the intracrystalline voids generated during the calcination step, as well as within the β-cages. However, the unidimensional molecular sieves AlPO4-11, AlPO4-5, and VPI-5 have only one type of adsorption site within their inner pores. The apparent activation energies of desorption (12.0-21.7 kcal mol-1) determined from the oxygen TPD results demonstrate that, as the pore size of the AlPO4 molecular sieve is larger, the interaction between the adsorbed oxygen and the molecular sieve framework becomes weaker.

    A spectroscopic investigation of the structure of alcohol-water solutions (1975)

    Notes: Abstract The v2 + v3 combination band of water has been recorded for nine alcohol-water solutions in which the volume fraction of water is less than 2% and for three alcohol-water solutions over the entire range of composition. In dilute solutions it was found that the fraction of “symmetrically” bonded water was, in general, smaller than in aprotic solvent-water systems. The fraction of nonbonded water protons was greater in alcohols of higher molecular weight and was also greater in tertiary alcohols than in primary ones. The 2vOH overtone band was recorded for three alcohols in alcohol-rich solutions. Water appears to break up the polymeric alcohol structure, and there appears to be a slight preference for water-water bonds over water-alcohol bonding. Raman spectra of the alcohol C−O stretching mode indicate that water-alcohol bonding is stronger than alcohol-alcohol bonding. The fraction of free alcohol and water OH groups appears to be smaller in solutions of intermediate composition than in the pure liquids. This increased “structure” of the solutions is consistent with the maxima occurring in the viscosity of alcohol-water solutions.
