The seasonal occurrence and among-plant and within-plant spatial distribution of the multivoltine leafminer Ophiomyia maura Meigen （Diptera： Agromyzidae） on the herbaceous plant Aster ageratoides Turcz. subsp, ovatus （Asteraceae） were investigated in the field. O. maura has at least four generations a year and mines per leaf fluctuate with a mean of 0.007 throughout the occurrence period. Seasonal occurrence is associated with abundance of new host leaves, suggesting O. maura females prefer to oviposit in newly emerged leaves. The among-plant distribution of O. maura is described by a Poisson distribution early in the season but tends to be weakly clumped later. The within-plant vertical distribution of larval mines increased from middle to upper leaves during plant development, because mined leaves in the middle position early in the season move downward with the emergence of new leaves, shifting mined leaves from the position where O. maura oviposits eggs. Later in the season, mined leaves remain where they are deposited because few new leaves emerge. The spatial distribution of O. maura, resource utilization patterns, and host plant characteristics are discussed.

We discuss cluster phenomena in light nuclei. As examples of typical cluster structures, we first review cluster structures of 12C, 16O, and 20Ne, and then introduce some topics of cluster phenomena in light neutron-rich nuclei such as Be and C isotopes. A particular attention is paid on coexistence of cluster and shell-model aspects.

We report our recent work on a hadronic molecule state of the KKN system with I =1/2 and jR = 1/2＋. We assume that the A（1405） resonance and the scalar mesons, f0（980）, ao（980）, are reproduced as quasi-bound states of KN and KK, respectively. Performing non-relativistic three-body calculations with a variational method for this system, we find a quasibound state of the KIlN system around 1910 MeV below the three-body breakup threshold. This state corresponds to a new baryon resonance of N＊ with JP ： 1/2＋. We find also that this resonance has the cluster structure of the two-body bound states keeping their properties as in the isolated two-particle systems. We also briefly discuss another hadronic molecular state composed by two K and one N, which corresponds to a resonance.

Objective To investigate the effects of isoflavone on body weight, fat mass, and gene expression in relation to lipid metabolism. Methods Thirty-six female SD rats were ovariectomized or sham-operated and fed on a high-fat diet. Two months later, abdominal incision was made, blood was collected to separate serum, and the liver and adipose tissue were immediately collected and weighed. Some portions of these tissues were frozen in liquid nitrogen and stored at -80℃. Results Ovariectomy （OVX） with a high-fat diet could induce obesity in rats, while treatment with isoflavone significantly inhibited the increase in body weight and fat mass in abdomen. Serum total cholesterol and leptin were significantly decreased in isoflavone group, compared with the OVX group. The mRNA expression of liver fatty acid synthase （FAS） in the OVX group was significantly higher than that in sham-operated group, while this difference was not observed in the isoflavone group. The mRNA expression of liver hormone-sensitive lipase （HSL） in the OVX rats tended to be lower than that in the sham-operated rats. Furthermore, a large amount of isoflavone maintained the mRNA expression at a sham level. Conclusion Isoflavone may prevent obesity induced by ovariectomy with a high-fat diet, in part by modulating gene expression related to lipid metabolism.

Cluster structures in light unstable nuclei are discussed. The structures of neutron-rich Be isotopes are theoretically investigated and the molecular orbital bond structure and its role in the vanishing of the neutron magic number N = 8 are discussed. The two-body cluster resonances in highly excited states of neutron-rich Li, Be and B isotopes are predicted theoretically.
