    Description / Table of Contents: Resume Cubitermes fungifaber, termite humivore de la forêt de Côte-d'Ivoire, construit un nid en terre par adjonctions successives. Quand le nid est soumis à des perturbations expérimentales, les colonies qui survivent peuvent émigrer par voie souterraine et construire un nouveau nid à quelque distance. Ce déménagement peut s'observer même en l'absence de perturbations visibles. De tels déménagements paraissent fréquents et pourraient être des événements normaux dans le développement de la société.
    Notes: Summary Cubitermes fungifaber, a humus-feeding termite from the forest of the Ivory Coast, builds an earthen nest by successive additions. When the nest is experimentally damaged, the surviving colony frequently migrates some distance away, by a subterranean route, and builds a new nest. This relocation sometimes occurs without any noticeable previous disturbance. We present evidence of the frequent occurrence of such relocations, which could be normal events during the development of the society.

    Interleukin-13 increases prostaglandin E2 (PGE2) production by normal human polymorphonuclear neutrophils by enhancing cyclooxygenase 2 (COX-2) gene expression (1998)

    Notes: Abstract. Objective: To investigate whether interleukin-13 (IL-13) can affect arachidonic acid metabolism and phagocytic activity of normal human polymorphonuclear neutrophils (PMN).¶Methods: Normal human PMN (1 × 106 cells/ml) were incubated with different concentrations of IL-13 (0.1–10 ng/ml) for a variety of times (30–120 min). Phagocytosis and intracellular cyclooxygenase-2 (COX-2) were detected by flow cytometry. The expression of COX-1 and COX-2 mRNA was detected by RT-PCR. The concentration of PGE2 in the PMN cultured supernatants was determined by EIA.¶Results: We found that IL-13 at an optimal concentration of 1 ng/ml significantly enhanced COX-2 gene expression and PGE2 production (121.57 ± 22.17 pg/ml in IL-13 stimulation vs. 73.16 ± 11.72 pg/ml in controls) by PMN. In addition, IL-13 stimulated PMN phagocytosis via increased complement receptor type 1 (CR1) and type 3 (CR3), but not IgG Fcγ receptor type 3 (FcγRIII). The cytoplasmic neutral esterase activity of PMN was also enhanced by IL-13 stimulation for 24 h.¶Conclusions: These results suggest that IL-13 can stimulate PMN and modulates the inflammatory reactions via the cyclooxygenase pathway.

    Stimulatory influence of the queen and king on soldier differentiation in the higher termitesNasutitermes lujae andCubitermes fungifaber (1986)

    Description / Table of Contents: Resume L'influence des reproducteurs sur la production de soldats a été étudiée chez deux espèces de termites supérieurs,Nasutitermes lujae (Nasutitermitinae) etCubitermes fungifaber (Termitinae). Dans les deux espèces, le couple royal stimule la production de soldats. Il se forme en moyenne 2 à 3 fois plus de soldats dans les élevages lorsque les reproducteurs sont présents. ChezN. lujae, le roi est aussi stimulateur que la reine. Les reproducteurs agissent à deux niveaux: ils induisent les mues et les orientent vers le type soldat. On peut maintenant affirmer que chezN. lujae, où une phéromone inhibitrice de soldats a été récemment mise en évidence, la proportion de soldats résulte de l'équilibre entre les actions stimulatrices des reproducteurs et les actions inhibitrices des soldats. La nature hypothétique de l'action stimulatrice royale est discutée.
    Notes: Summary The influence of the reproductives on soldier production was studied in two species of higher termites,Nasutitermes lujae (Nasutitermitinae) andCubitermes fungifaber (Termitinae). In both species, the royal pair has a stimulatory influence on soldier production. The soldier molts are two to three times more numerous when workers are reared with the reproductives. InN. lujae, the king and the queen have an apparently equal stimulatory influence. The reproductives act on both induction and orientation of the molts toward the soldier type. It can be now claimed that inN. lujae, in which the existence of an inhibitory soldier pheromone was recently evidenced, the proportion of soldiers results from the balance between the stimulatory influences of the reproductives and the inhibitory influences of the soldiers. The hypothetical nature of the royal stimulatory influence is discussed.

    Notes: Abstract Four cases of gastric diverticula following subtotal gastrectomy are described. This type of diverticula associated with partial gastrectomy are probably true, acquired, pulsion diverticula. In two of our patients the diverticula were associated with significant prolapse of gastric mucosa causing obstruction at the anastomosis.

    210Pb-derived sediment accumulation rates in the southwestern East Sea (Sea of Japan) (1997)

    Notes: Abstract  Recent sediment accumulation rates are 18–230 mg cm-2 yr-1 (0.02–0.2 cm yr-1) based on excess 210Pb activity profiles in the southwestern part of the East Sea (Sea of Japan). Assuming no mixing beneath surface mixed layers, 210Pb-derived sediment accumulation rates are 18–32 mg cm-2 yr-1 in the northern part of the Yamato Ridge and the Ulleung Basin, 29–136 mg cm-2 yr-1 in the Korea Plateau, and 230 mg cm-2 yr-1 in the southern shelf. These values generally agree with long-term sedimentation rates estimated from dated ash layers.

    Notes: Abstract Clay minerals of the surface sediments of Bransfield Strait, Antarctica, exhibit distinctive geographical distributions: kaolinite has the highest concentration near the shore of the South Shetland Islands in the northern strait (20%); chlorite, near Smith Island in the northwestern strait; illite, on the continental shelf off the Antarctic Peninsula in the southern strait (80%); and smectite, close to the Penguin and Bridgeman islands in the northeastern strait (25%). This distribution pattern, combined with hydrographic and climatic data for the strait, are used to infer clay mineral provenance and dispersal patterns.

    Altered cutaneous innervation in psoriatic skin as revealed by PGP 9.5 immunohistochemistry (1991)

    Notes: Summary There is conflicting evidence in the literature as to whether cutaneous nerves are altered in psoriasis or not. In this study, antibodies to protein gene product (PGP) 9.5 were used to visualize cutaneous nerves in biopsies from involved and uninvolved skin of nine patients with psoriasis and from normal skin of eight healthy controls. A profound reduction in the epidermal nerve fibre density was observed in the involved psoriatic skin. These intraepidermal nerve fibres were also mostly short and found in the basal layer. Only a few nerve fibres were found in the suprabasal layer and they were non-varicose, long fibres going straight up without branching. In the uninvolved skin of psoriatic patients, the distribution and number of the intraepidermal nerve fibres was similar to that observed in normal skin. In the dermis, the distribution and the number of the nerve fibres showed no differences between involved psoriatic skin, uninvolved psoriatic skin, and normal skin. The results support previous studies in which alterations of cutaneous nerves in psoriasis have been described.
