VOGEL, S; Duke University: Biological Relevance of the Peclet Number Exchange processes commonly use forced convective flows to augment molecular diffusion. A dimensionless index, the P�clet number (vl/D), indicates the relative magnitude of the two processes. Its value can provide a functional rationale for specific structures and processes, and it can suggest situations in which […]

BOWKER, G.E.; Furman University: A mathematical evaluation of wind, gravitational, and electrostatic forces in pollen capture. Under typical pollination conditions (clear skies), plants carry a net negative charge. This charge is located on the skyward distal parts of the plants, and is concentrated at points (e.g. the edges of leaves, the tips of needles, and […]

BECKMAN, BRIAN; SHIMIZU, MUNETAKA; GADBERRY, BRAD; PARKINS, PAUL; COOPER, KATHY; National Marine Fisheries Service; University of Washington; University of Washington; National Marine Fisheries Service; University of Washington: Temperature and the relations among plasma IGF-I, 41 kDa IGFBP, and growth in coho salmon. The effects of environmental variation on the IGF-I system and subsequently on growth […]

WOOD, AW; DUAN, C; Univ of Michigan, Ann Arbor: Targeted gene knockdown reveals an important role for insulin-like growth factor binding protein-2 in zebrafish embryonic development The insulin-like growth factor (IGF) system plays a central role in mediating fetal and postnatal growth in vertebrates. The major players in this hormone system are the peptide growth […]

DAVIS, K. B.; PETERSON, B.; HKD-SNARC/ARS/USDA, Stuttgart, AR; CGRU/ARS/USDA, Stoneville, MSLike: Insulin-Like Growth Factor and IGF Binding Proteins in Sunshine Bass Growth of fish is regulated by components of the pituitary-liver-somatic tissue axis. The influence of growth hormone from the pituitary is,in part, to stimulate the liver to synthesize and release insulin-like growth factors (IGF-I […]

PICHA, M.E.*; FRUCHTMAN, S.; NOGA, E.J.; BORSKI, R.J.; North Carolina State University, Raleigh: Increases in insulin-like growth factor-I during compensatory growth in a teleost fish Compensatory growth is an accelerated growth state that exceeds normal rates when animals are alleviated of certain growth-stunting conditions. Little is known of the hormonal control of compensatory growth in […]

DING, J; DUAN, C; Univ. of Michigan, Ann Arbor: IGF binding protein-5 is required for the pharyngeal skeleton formation in vivo IGFBPs are a conserved family of proteins that bind to IGFs and modulates IGF bioactivity. Some IGFBPs may also possess intrinsic biological activities that are IGF-independent. Their in vivo physiological functions of IGFBPs, however, […]

BREUNER, C.W.*; WADA, H.; SHYU, J.; LOVE, O.P.; University of Texas at Austin; University of Texas at Austin; University of Texas at Austin; Simon Fraser University: Corticosteroid Binding Globulin Capacity Responds to Chronic Hormone Treatment but not Acute Stressors There is increasing evidence that corticosteroid binding globulins (CBG) regulate glucocorticoid action in surprising and unpredictable […]

WEISBLAT, D.A.; REN , X.*; GONSALVES, F.C.; Univ. of California, Berkeley; Univ. of California, Berkeley; Univ. of California, Berkeley: Paradoxical aspects, and their possible evolutionary implications, of cell fate determination and cell signaling in the early embryo of Helobdella robusta, a glossiphoniid leech Though highly derived, leeches are among the best studied representatives of the […]

ZANOL, J.; FAUCHALD, K.; George Washington Univ. ; NMNH, Smithsonian Institution: Looking for more morphological information, a study of morphological characters in Eunicidae (Eunicida, Polychaeta, Annelida) One current problem in morphological phylogenetic studies of Polychaeta is the lack of knowledge about variability of diagnosing characters which makes the establishment of accurate primary hypotheses of homology […]
