Postembryonic development and lifestyle shift in the commensal ribbon worm.

Background: Various morphological adaptations are associated with symbiotic relationships between organisms. One such adaptation is seen in the nemertean genus Malacobdella. All species in the genus are commensals of molluscan hosts, attaching to the surface of host mantles with a terminal sucker.

Application of Braided Piezoelectric Poly-l-Lactic Acid Cord Sensor to Sleep Bruxism Detection System with Less Physical or Mental Stress.

For many years, we have been developing flexible sensors made of braided piezoelectric poly-l-lactic acid (PLLA) fibers that can be tied and untied for practical applications in society. To ensure good quality of sleep, the occurrence of bruxism has been attracting attention in recent years. Currently, there is a need for a system that can easily and accurately measure the frequency of bruxism at home.

Synthesis of azide-modified glycerophospholipid precursor analogs for detection of enzymatic reactions.

Glycerophospholipids (GPLs) are major cell membrane components. Although various phosphorylated molecules are attached to lipid moieties as their headgroups, GPLs are biosynthesized from phosphatidic acid (PA) via its derivatives, diacylglycerol (DAG) or cytidine diphosphate diacylglycerol (CDP-DAG). A variety of molecular probes capable of introducing detection tags have been developed to investigate biological events involved in GPLs.

Three new species in Ehrenberg, 1828 (Nemertea, Monostilifera) from sublittoral to upper bathyal zones of the northwestern Pacific.

Monostiliferous nemerteans in the genus Ehrenberg, 1828 are generally characterized as having four eyes, and they occur worldwide, from the intertidal zone to the deep-sea bottom. Recent extensive sampling of has explored the high species diversity, including many undescribed forms, but phylogenic analysis has revealed non-monophyly of the genus. We herein describe three new species of the genus (, , and ) from northwestern Pacific waters based on specimens collected by dredging or by use of a remotely operated vehicle at depths of 116-455 m.
