The relation between the vertical migration in summer and spawning of a littoral-fringe periwinkle,Nodilittorina exigua, was studied by field observations and laboratory experiments. The snails moved down soon after the first appearance of their
planktonic eggs in the sea and stayed at low shore-levels until early August. It was shown that the migration increased the
chance of immersion of the snails, and therefore of releasing eggs by the females. Females immersed every day in the laboratory
released more eggs than those which experienced some days of exposure to air, during the same period. The results obtained
suggest the reproductive advantage of immersion at low levels. Nevertheless, the snails moved upward before the end of the
spawning season. Typhoon swells increasing in frequency through the summer seemed to be responsible for the upward migration. 相似文献

Techniques for partitioning cell adhesion are useful tools in biological and medical experiments. However, conventional cell patterning methods require special apparatus, special materials or high-level skills. Therefore, we have developed a new cell patterning methodology which can be easily carried out in biological laboratories. Non-cell adhesive material including hydrogel or gas patterns to restrict cell adhesion on a culture dish or glass substrates can be constructed by exploiting a polydimethylsiloxane (PDMS) mold with microchannels. The PDMS molds suck non-adhesive materials into microchannels from the inlet of the microchannels and the materials are immobilized onto the substrates with a desired pattern. High resolution under a few micrometers and long-term stability can be realized. This method has been used for analysis of stem cells, muscle cells, neuron development and other cells in collaboration with many biological researchers. Several examples to use this technique are introduced in this review. 相似文献

A female patient with systemic lupus erythematosus (SLE) developed pulmonary aspergillosis with staphylococcal pneumonia and hepatic candidiasis.Aspergillus terreus, which is a rare causative organism of pulmonary aspergilosis, was identified from a pulmonary lesion by culture. The aleurioconidium production, a characeristic of the genusAspergillus sect.terrei, was demonstrated on short and irregular hyphal features in tissue sections. This report is the first of a combined case of pulmonary aspergillosis due toA. terreus with infections caused by other microorganisms. 相似文献
