    Thermochromism in the insulating forms of polyaniline: Role of ring-torsional conformation (1992)

    Notes: The temperature-dependent optical spectra of the major insulating forms of polyaniline—the fully reduced leucoemeraldine base, half-oxidized emeraldine base (EB), and fully oxidized pernigraniline base (PNB)—and of two oligomeric model compounds for polyaniline are reported. All three forms of the polymer possess a ∼3.8 eV optical absorption assigned to a transition from the valence band to a narrow π* conduction band; in all cases this transition shifts to higher energy and weakens with increasing temperature, T. The oxidized forms also exhibit transitions at ∼2 eV; in EB, this absorption feature has previously been assigned to a "molecular exciton'' and is found to increase in energy with increasing T. In PNB, the observed ∼2.3 eV transition is correlated with the expectation of a Peierls dimerization gap in this half-filled band system; in contrast to the ∼2 eV transition in EB, this optical transition energy decreases with increasing T in PNB. These observations are for the most part understood by a simple model which accounts for the steric repulsion between the constituent phenyl rings of the polymer chain. The dependence of the steric potential on ring angle is anharmonic, giving rise to thermal expansion of the average phenyl ring-torsion angles and a concomitant reduction in the bandwidth and average energy of the valence band; the observed thermochromic behavior is generally consistent with these changes in electronic structure. The potential role of other conformational changes—rod-to-coil transitions, order–disorder transitions, bond-length order changes, and structural isomerizations—is discussed.

    Notes: [Auszug] SIR-In response to J.G. Wilson (Nature 328, 288; 1987), we should like to present our case against a total academic boycott of our scientists. We have no doubts that trade and sports boycotts against South Africa have been effective; any government moves towards reform can be ...

    Identification of synergistic combinations of spirogermanium with 5-fluorouracil or cisplatin using a range of human tumour cell lines in vitro (1984)
    Springer
    Investigational new drugs 2 (1984), S. 29-33

    ISSN: 1573-0646
    Keywords: spirogermanium ; synergistic drug combinations ; human tumour cell lines ; 5-fluorouracil ; cisplatin

    Topics: Chemistry and Pharmacology , Medicine
    Notes: Summary A series of continuous human tumour cell lines, derived from various tumour types, were used to establish whether the combination of spirogermanium (SP) with other ‘standard’ antitumour drugs proved superior to these as single agents in reducing cell survival in vitro. A non-cytotoxic concentration of SP was selected and when combined with a range of concentrations of cisplatin or 5-fluorouracil (5-FU), definite synergistic cell kill was noted in all lines tested. In contrast, the combination of SP with various other antitumor drugs, including adriamycin, methotrexate and the vinca alkaloids and with X-irradiation did not enhance cytotoxicity. These pre-clinical in vitro studies suggest that benefit may accrue from combining SP with either 5-FU or cisplatin and provide a basis for their clinical evaluation in colo-rectal tumours or transitional cell cancer of the bladder, respectively.

    Mitochondrial Sequences as Indicators of Genetic Classification in Bush Babies (2000)
    Springer
    International journal of primatology 21 (2000), S. 889-904 
    Details
    ISSN: 1573-8604
    Keywords: Galago ; bush baby ; mitochondrial genes ; phylogeny ; systematics
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract Systematic relationships among the African bush babies are not well understood. Various generic designations are currently in use. Some authors refer all species to a single genus (Galago), while others recognize ≤4 genera. Phylogenetic reconstructions based on morphology, karyology, allozymes and vocal repertoires have generated inconsistent hypotheses of relationship. We analyzed partial sequences of three mitochondrial genes (270 bp from cytochrome b, 387 bp from 12S rRNA, and 241 bp from 16S rRNA, total 898 bp) to resolve some uncertainties. We sampled taxa from each of three genera: Galagoides alleni, G. demidoff and G. zanzibaricus; Galago senegalensis, G. gallarum and G. moholi; and Otolemur crassicaudatus and O. garnettii. Outgroup taxa were Asian lorises: Nycticebus coucang and Loris tardigradus. We analyzed sequences separately and in combination, and modeled phylogenies using maximum parsimony, weighted parsimony, neighbor-joining and maximum-likelihood. We obtained some variation in phylogenetic inference depending on sequence and analytical method, but the results also gave strong phylogenetic signals. The lesser bush babies invariably formed a clade, showing evidence of very recent radiation. The greater bush babies also formed a clade, marked by somewhat greater interspecific genetic distances, which was allied with Galagoides alleni in most instances. Galagoides demidoff and G. zanzibaricus are not closely related, though both diverged early in the history of the group. A genus comprising Galagoides alleni, G. demidoff and G. zanzibaricus is not supported by our data. The most likely alliance for Galagoides alleni is within the genus Otolemur. Of the three partial sequences employed in the study, 16S rRNA gave the most consistent results, while cytochrome b was least informative.

    Loud calls ofGalago crassicaudatus andG. garnettii and their relation to habitat structure (1991)
    Springer
    Primates 32 (1991), S. 153-167

    ISSN: 0032-8332
    Keywords: Galago crassicaudatus ; Galago garnettii ; Loud calls
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract Long distance vocalizations have been shown to be good indicators of genetic species in primates. Here the loud calls of two recently identified greater galago taxa —Galago crassicaudatus andG. garnettii — are compared and analyzed statistically. Observed differences in call structures are investigated further as potential indicators of differences in the structures of habitats frequented by the two species. Although the calls share a repetitive structure, and show similar dominant frequency bands (1,000 – 1,500 Hz), they differ significantly in the number of units per call, unit duration, inter-unit interval, highest frequency, lowest frequency, dominant frequency band, first harmonic, and call duration. The duration of theG. crassicaudatus call is more than twice that ofG. garnettii. Strong intraspecific consistency is seen in the most energetic frequency bands (dominant frequency band and first harmonic), and durations of the individual units and inter-unit intervals. Information important to species recognition is thus most likely to be contained in these features. Individual recognition may be encoded in the relative emphasis of higher level harmonics. The frequency structures of the calls will reflect requirements for acoustical transmission in a forest environment, as well as structural constraints imposed by body size. Higher frequencies detected in theG. garnettii call (up to 8,500 Hz) may have a functional significance related to distance estimation, or may simply be a reflection of smaller body size. The greater modulation of theG. garnettii call suggests that its habitat constitutes a denser or more turbulent medium for sound transmission than does the habitat ofG. crassicaudatus.
