    Anchorage of embryos in Spirorbinae (Polychaeta) (1972)

    Notes: Abstract Methods of incubation are taxonomically important in Spirorbinae. About half of the known species incubate in the operculum, but the remainder are usually described simply as “incubating within the tube”. Studies of tube incubation show that the embryos are anchored in various ways. They form an egg string, which is attached to the tube by a posterior filament in Spirorbis and Spirorbella; they adhere more generally to the tube wall in Circies and Paradexiospira; they are attached to specialised thoracic stalks in Protolaeospira, Helicosiphon and Romanchella; they adhere to the body surface in Metalaeospira and probably in Eulaeospira; they are not attached to either body or tube in Paralaeospira. Tube incubation is found predominantly in temperate or cold waters. In most species from the southern hemisphere, embryos are anchored to the bodies of the parents, but in most species from the northern hemisphere, embryos are fixed to the walls of the parent tubes.

    Notes: Abstract Five Antarctic or south-temperate species of Spirorbiaae are centred in south-west Africa, whilst 6 tropical species extend round the south-east and another 4 are recorded from Mozambique. Of the three new species, Pileolaria (Pileolaria) annectans sp. n. has a rudimentary opercular plate surmounting a sort-walled sac of embryos, which somewhat resembles a “thoracic brood pouch”. Pileolaria (Pileolaria) dayi sp. n. has a helmet-like brood chamber, but this opens distally, like the brood cups found in the subgenus Duplicaria. Janua Pil-natalensis sp. n. has the dorsal collar folds usually separate, but partially fused in some juveniles.

    Segregation of linked probes to myotonic dystrophy in a family demonstrating that 152 and APOC2 are on the same side of DM on 19q (1988)

    Notes: Summary The two markers most closely linked to the myotonic dystrophy (DM) locus on chromosome 19 are the gene that codes for apolipoprotein CII (APOC2) and the anonymous probe D19S19 (LDR152). Both of these markers show tight linkage to DM, with maximum lod scores of〉20 at recombination fractions of less than 0.05. We have identified, in a family in which DM segregates, an affected individual where a meiotic recombination event has occurred in which both of these linked markers have crossed over with the gene defect. This demonstrates that APOC2 and D19S19 are probably on the same side of DM.

    A simple method for elution of IgA deposits from the skin of patients with dermatitis herpetiformis (1989)

    Notes: Summary To better understand the role of autoimmunity in the pathogenesis of dermatitis herpetiformis, linear IgA bullous dermatosis or other skin disorders, the antigenic specificity of the immune reactants bound in vivo in the skin must be identified. In order to do so, one must first be able to elute these immune reactants from the skin. We describe here a simple method of eluting not only specifically bound IgG, but also IgA and other immunoglobulins and complement components from skin biopsy material. The method involves cutaneous washing of the entrapped serum proteins in PBS pH 7 and pH 5 buffers followed by specific immunoglobulin elutions at pH 3 and 2. The IgA deposits which could not be removed by this treatment were eluted by a combination of low pH (0.5 M citrate pH 2) and a chaotropic agent (2 M NaCl). The relative concentration of IgA in eluates when quantitated by fluoroimmunoassay were three-to five-fold higher in dermatitis herpetiformis skin biopsy specimens, than in eluates of bullous pemphigoid or normal skin biopsy specimens.

    Non-tuberculous mycobacterial lymphadenitis in children (1989)

    Notes: Abstract Eighty-six children (44 males, 42 females) were identified as having non-tuberculous mycobacterial lymphadenitis. The diagnostic criteria were either culture of the organism from the affected lymph node (n=68), or, when culture was negative, a positive skin test with non-tuberculous mycobacterial antigens and negative skin test responses to tuberculin purified protein derivative (PPD) in association with typical histological features (n=18). All children had histopathological findings of granulomatous inflammation with caseation and/or acid-fast bacilli. Eighty-two percent of the children were under 5 years of age at presentation and 30% were less than 2 years old. Most (79%) were city dwellers. Lymph node enlargement had been present for less than 6 months in almost all children (97.5%) and was almost exclusively in the face and neck region (97%). Disease was confined to the involved lymph nodes in 56% but had extended beyond the confines of the infected node to form a collar stud abscess in 38% and 6% presented with a skin sinus. Extranodal extension did not show any statistically significant association with the duration of lymphadenopathy. The duration of lymphadenopathy had been greater in those children in whom an organism was not isolated on culture resected tissue χ2, P〈0.01). All children were treated surgically, and recurrence occurred in five patients. This study describes the clinical and demographic characteristics of non-tuberculous mycobacterial lymphadenopathy in children in a population in which tuberculous adenitis is rare. Recognition of these features may allow earlier diagnosis and appropriate surgical therapy.

    Efficient and selective population of high vibrational levels by stimulated near resonance Raman scattering (1987)

    Notes: We report the successful application of an optically pumped molecular beam laser for efficient and selective population transfer from v″=0 to high lying vibrational levels of Na2 in the electronic ground state. More than 50% of the molecules in a thermally populated rotational level of v″=0 can be transferred to a state v″(very-much-greater-than)1 with typically ≥75% of the molecules excited out of the initial state found in the predetermined end vibrational level and approximately ≤25% distributed over other levels according to the Franck–Condon factors. The applicability of this technique to the study of collision processes involving vibrationally highly excited levels is discussed. This work also contributes in general to a better understanding of optically pumped dimer lasers.

    Mechanism of CO bond scission at alkali promoter sites—IRAS study of the system CO/K/Ni(111) (1987)
    College Park, Md. : American Institute of Physics (AIP)

    Notes: IRAS (infrared reflection absorption spectroscopy) has been employed to study the isotopic mixing reaction: 13C16O(a)+12C18O(a)→13C18O(a)+12C16O(a) on Ni(111) with preadsorbed K adatoms. Under high temperature conditions (T〉450 K) where the isotopically mixed CO is being desorbed, it has been shown that the isotopic exchange reaction cannot be detected by IRAS on the surface among CO molecules strongly interacting with K adatoms. This result implies that dissociation of CO occurs at K-promoted Ni sites followed by surface diffusion of C(a) and O(a) away from the K promoter site. Statistical recombination of C(a)+O(a) occurs with concomitant CO desorption on Ni(111) sites some distance from K centers. The empty K-promoted sites may be refilled by surface diffusion of CO from outside. Thus, alkali metal promotion of C–O bond scission may act via a "feeder-site'' mechanism connecting promoter atoms to external surface sites via surface diffusion of atomic C and O species.
