Cell adhesion play. pivotal roles in the morphogenesis of multicellular *** cells form several ty.es of cell-to-cell adhesion,including zonula occludens(tight junctions),zonula adhaerens(adherens junctions),and macula adhaerens(desmosomes).Although these adhesion complexes are basically.observed only.in epithelial cells,cadherins,which are the major cell adhesion molecules of adherens junctions,are expressed in both epithelial and non-epithelial tissues,including neural tissues(Kawauchi,2012).The cadherin superfamily.consists of more than 100 members,but classic cadherins.

Superparasitism in solitary.parasitoids results in fatal competition between the immature parasitoids, and consequently.only.one individual can emerge. In the semisoli- tary.ovicidal parasitoid Echthrodelphaxfairchildii （Hy.enoptera： Dry.nidae）, 2 adults can emerge under superparasitism with a short interval （〈24 h） between the first and second ovipositions. We determined the female parasitoid＇s behavioral responses under self- and conspecific superparasitism bouts with first-to-second oviposition intervals of 〈2 h. The self- and conspecific superparasitizing frequencies increased up to an oviposition interval of 0.75 h, with the former remaining lower than the latter, particularly.for oviposition intervals of _〈0.25 h, suggesting the existence of self-/conspecific discrimination. The superparasitizing frequency.plateaued for oviposition intervals of _〉0.75 h, with no dif- ference between self- and conspecific superparasitism. The ovicidal-probing frequency.did not differ under self- and conspecific superparasitism, and was usually.〈20%. The females exhibited no preference for the oviposition side （i.e., ovipositing on the side with or without the first progeny. and almost alway. laid female eggs for any.oviposition in- terval under self- and conspecific superparasitism. The sex ratio was not affected by.the ty.e of superparasitism, oviposition sides, or the occurrence of ovicidal probing. These observed results about the oviposition side, ovicidal probing, and sex ratios differed from the predictions obtained assuming that the females behave optimally. Possible reasons for the discrepancies are discussed： likely.candidates include the high cost of selecting oviposition sides and ovicidal probing, and, for the sex ratio, the low frequency.of encountering suitable hosts before superparasitism bouts.

We assessed the adaptiveness of refraining from infanticidal probing at the third attack under triple parasitism in the parasitoid Echthrodelphaxfairchildii Perkins, by.comparing fitness returns from the third attack with and without probing. Fitness returns were assessed in terms of the survival rate, mean developmental time, and mean adult head width of the progenies. Not probing was maladaptive under triple parasitism with oviposition intervals of 1/24 and 24/24 hours （where the numbers before and after the slash refer to the first-to-second and second-to-third oviposition intervals, respectively., although no significant difference was detected in fitness returns for oviposition intervals of 24/1 hours. We suggest that the cost of probing （especially.the decrease in the chance of future ovipositions） is a reason for the seemingly.maladaptive absence of probing.

A sy.thetic poly.er with a laminin-apatite composite lay.r on its surface would be useful as a percutaneous device. The preparation of such a composite was attempted in the present study.using poly. ethy.ene terephthalate ）（PET） and poly.thy.ene （PE） as the sy.thetic poly.er. PET and PE plates and those pretreated with an oxy.en plasma were alternately.dipped in calcium and phosphate ion solutions, and then immersed in a metastable calcium phosphate solution supplemented with laminin （ LCP solution ）. The PET and PE plates pretreated with an oxy.en plasma formed a uniform and continuous lay.r of a laminin-apatite composite on their surfaces. In contrast, the PET and PE plates that had not been pretreated with an oxy.en plasma did not form a continuous lay.r of a laminin-apatite composite on their surfaces. The hy.rophilic functional groups on the PET and PE surfaces introduced by.the plasma treatment were responsible for the successful laminin-apatite coruposite coating.

A broadband frequency.tunable microwave reflectometer sy.tem, which has the abil- ity.of fast and stable frequency.sweeping operation, is applied in the large helical device （LHD） to measure the boundary.of the high-temperature plasma. When the microwave is launched, with extraordinary.polarization, from the low field side of the magnetic field with its frequency.swept from low to high, the microwave of minimum right-hand cut-off frequency.is reflected most out- side. We can then estimate the plasma boundary.position by.measuring the change of the reflected power from the cut-off lay.r.
