  1. A lobster phospholipase C-beta that associates with G-proteins in response to odorants.

    Journal of Neuroscience 19(12):4881 (1999) PMID 10366622

    These results support the conclusion that lobPLCbeta mediates olfactory transduction....
  2. Ultrastructure of the larval tentacle and its skeletal muscle in Xenopus laevis.

    Tissue and Cell 30(2):216 (1998) PMID 9661294

    We have classified the skeletal muscle fibers of the larval tentacular muscle into three types: large (30-50 microns), intermediate (20-30 microns), and small (10-20 microns). By electron microscopy, each type displays characteristic sarcomeric banding patterns, sarcotubular and mitochondrial dispos...
  3. Locomotor function of the dorsal fin in teleost fishes: experimental analysis of wake forces in sunfish.

    Journal of Experimental Biology 204(Pt 17):2943 (2001) PMID 11551984

    We have a very limited understanding of the functional significance of this evolutionary variation in dorsal fin design. To initiate empirical hydrodynamic study of dorsal fin function in teleost fishes, we analyzed the wake created by the soft dorsal fin of bluegill sunfish (Lepomis macrochirus) du...
  4. Function and cellular localization of farnesoic acid O-methyltransferase (FAMeT) in the shrimp, Metapenaeus ensis.

    FEBS Journal 269(14):3587 (2002) PMID 12135499

    We have previously cloned and characterized the shrimp FAMeT. In the present study, recombinant FAMeT (rFAMeT) was produced for bioassay and antiserum generation. FAMeT is widely distributed in shrimp tissues with the highest concentration observed in the ventral nerve cord. Interestingly, an additi...
  5. Twisting and bending of biological beams: distribution of biological beams in a stiffness mechanospace.

    Biological Bulletin 205(1):36 (2003) PMID 12917220

    Most biological beams bend and twist relatively easily compared to human-made structures. This paper investigates flexibility in 57 diverse biological beams in an effort to identify common patterns in the relationship between flexural stiffness and torsional stiffness. The patterns are investigated...
  6. Median fin function in bluegill sunfish Lepomis macrochirus: streamwise vortex structure during steady swimming.

    Journal of Experimental Biology 209(Pt 8):1516 (2006) PMID 16574809

    I analyze flow in the transverse plane at a range of positions around bluegill sunfish Lepomis macrochirus, from the trailing edges of the dorsal and anal fins to the near wake. Simultaneous particle image velocimetry and kinematic measurements were performed during swimming at 1.2 body lengths s(-1...
  7. Extrusive bacterial ectosymbiosis of ciliates.

    Progress in Molecular and Subcellular Biology 41:97 (2006) PMID 16623391

  8. [The cases of teratology in Mallophaga of South Africa].

    Wiadomosci Parazytologiczne 47(1):103 (2001) PMID 16888959

    The following types ofteratology were found in the collection of 1278 individuals of Mallophaga coming from the birds of South Africa origin: deformity clypeus in Quadraceps kilimandjarensis (KELL.) from Stephanibyx coronatus (BURCH.), partial atrophy of one of the antennae of two males Q. kilimandj...
  9. A newly discovered species of living baleen whale.

    Nature 426(6964):278 (2003) PMID 14628049

    We collected a medium-sized baleen whale carcass on a coastal island in the Sea of Japan. This specimen and the previously collected eight specimens resembled Balaenoptera physalus (fin whale) in external appearance but were much smaller. Comparison of external morphology, osteology and mitochondria...
  10. Fine structure and probable function of ring organs in the mite Histiostoma feroniarum (Acari: Actinotrichida: Acaridida: Histiostomatidae).

    Journal of Morphology 253(3):255 (2002) PMID 12125064

    Histiostoma feroniarum, like other histiostomatid mites, possesses peculiar ring organs that are visible under the light microscope as ventrally located, characteristic rings of sclerotized cuticle. The ring organ is composed of three elements: a disc of modified cuticle, ring organ cells located un...
