    Notes: The ciliated protozoan Paramecium contains hemoglobin in heterogeneous monomeric forms. In particular, Paramecium caudatum is characterized by the presence of a major component called Hb10 and a basic component named bHb. We found that in P. caudatum both of these hemoglobin components show some variation according to stock. The types and distributions of these hemoglobin components were examined on 16 stocks in five different syngens and one stock in an unidentified syngen using high performance liquid chromatography. The results indicate that in a variety of stocks the major component, Hb10, was divided into three types, A, B or A + B, and that the basic hemoglobin component was composed of a combination of two or three variants out of four possible, i.e. bHb 1, bHb 2, bHb 3 and bHb 4. Neither the Hb10 types nor the bHb variants, however, could be used to distinguish syngen in P. caudatum, since all of the Hb10 types and bHb variants were widely distributed over syngens and identical profiles appeared to some stocks in different syngens.

    Biochemical genetic evidence for a hybrid origin of spined loach, Cobitis taenia taenia, in Japan (1994)

    Topics: Biology
    Notes: Starch gel electrophoresis and isoelectric focusing were performed on sarcoplasmic proteins from three taxa of cobitid fish in Japan, Cobitis biwae, C. taenia striata and C. l. taenia. These taxa are hardly distinguishable from each other by external appearance or morphological characters. Electrophoretic patterns of sarcoplasmic proteins from white muscle suggested fixed allelic differences between C. biwae and C. t. striata at two protein-coding loci (parvalbumin and creatine kinase). The third taxon, C. t. taenia, showed composite banding patterns with respect to the above two proteins, suggesting C. t, taenia originated from hybridization between C. biwae and C, t. striata. Previously, C. t, taenia and C. t. striata were believed to have shared a common ancestor subsequent to their divergence from C. biwae.

    Estimation of the Outcrossing Rate on Dryobalanops aromatica Gaertn. f. in Primary and Secondary Forests in Brunei, Borneo, Southeast Asia (1994)
    Oxford, UK : Blackwell Publishing Ltd
    Plant species biology 9 (1994), S. 0

    Topics: Biology
    Notes: Abstract Dryobalanops aromatica is an emergent canopy tree species with hermaphroditic bee-pollinated flowers. This species is distributed in the lowland dipterocarp forests of Malaya, Sumatra, Rhio Archipelago and Borneo. The flowering of many different dipterocarp species was observed in some parts of Brunei in 1991, and all over Brunei in 1992. The outcrossing rates of D, aromatica were estimated in 1991 and 1992 in the secondary forest, and in 1992 in the primary forest. Selective harvesting of D. aromatica has occurred in the secondary forest about 20 years ago. Four enzyme systems with a total of six isozyme loci were used to estimate the single locus and the multilocus outcrossing rates. The multilocus outcrossing estimates ranged from 0.794 to 0.856, with a mean of 0.816. These estimates are similar to those for other tropical tree species. Although the flowering density of D. aromatica in the secondary forest was lower than in the primary forest, the multilocus outcrossing estimates were not significantly different. The variation between years in the secondary forest was also not significant. These findings may be largely the result of the high flowering tree density of this species, even in the secondary forest. In this study, the outcrossing rates of D. aromatica were maintained by high flowering density regardless of the size structure or the topography of the habitat.

    Penicillin-binding proteins in Mycobacterium smegmatis (1984)
    Oxford, UK : Blackwell Publishing Ltd
    FEMS microbiology letters 25 (1984), S. 0 
    Details
    ISSN: 1574-6968
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Biology
    Notes: Abstract The penicillin-binding proteins (PBPs) of Mycobacterium smegmatis were studied. Five PBPs ranging in Mr from approx. 114000 to 25000 were detected in the cytoplasmic membrane. The affinities of the PBPs for selected β-lactam antibiotics were determined. Most of the antibiotics bound to PBPs 3 and 4 at low concentrations. A penicillin-susceptible mutant and a cefmetazole-resistant mutant were isolated by selection in vitro. The PBPs of these mutants were identical to those of the parent strain. The affinity of cefmetazole for the individual PBPs was identical in each mutant.

    Dielectric relaxation of polyorganophosphazenes (1992)
    Springer
    Journal of inorganic and organometallic polymers and materials 2 (1992), S. 255-267 
    Details
    ISSN: 1572-8870
    Keywords: Polyorganophosphazene ; dielectric relaxation ; two-site model ; conformation analysis
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology
    Notes: Abstract Dielectric relaxation spectra of poly(bis-trifluoroethoxy phosphazene) (PBFP), poly(bis-n-propoxy phosphazene) (PBPP), and poly(bis-n-propylamino phosphazene) (PBPAP) were measured in wide temperature and frequency regions, and the α-relaxation caused by micro-Brownian motion of segments in the rubbery state and the β-relaxation due to the local motions of the polymer in the glassy region were observed. The dielectric spectra of PBFP at temperatures higher than the rubbery region exhibited a mesophase transition at 358 K. From conformation analysis according to the two-site model, it has been elucidated that the mechanism for β-relaxation of these samples is hindered internal rotation of the side groups.

    Description / Table of Contents: Übersicht Behandelt wird die Formulierung der Randintegralgleichung für den axialsymmetrischen, elastisch transversal-isotropen Körper. Es wird angenommen, daß die Achse der elastischen Symmetrie mit der Rotationsachse zusammenfällt und der Körper einer beliebigen axialsymmetrischen Belastung ohne Torsion unterworfen ist. Ausgeführte numerische Beispiele werden mit Ergebnissen der Finite-Element-Methode verglichen.
    Notes: Summary In this paper we deal with the formulation of the axisymmetric boundary integral equation for the transversely isotropic elastic body. We assume that the axis of elastic symmetry is coincident with the axis of rotation and that the elastic body is subjected to arbitrary axisymmetric loading without torsion. Numerical calculations are carried out and compared with results by the finite element method.

    Notes: Summary In this paper we deal with the one of the ways to obtain a free-space Green's function of a transversely isotropic infinite elastic medium which is subjected to a ring-like axisymmetric loading. We assume that the loading is torsionless. To solve the problem, we introduce two potential functions and apply the Hankel and the Fourier transforms. As a special case we solve the same problem of the isotropic medium.
