BERG, L. K.; DESAI, P.; AROPE, S.; KELLEY, K. M.; California State University, Long Beach: Insulin-like Growth Factor-binding Protein-2 (IGFBP-2) as a Possible Mediator for Angiotensin II (AngII) and Glucose-activated Kidney Mesangial Cells Kidney glomerular mesangial cells exhibit activated proliferation and an over-production of extracellular matrix (ECM) in diabetic kidney cells or in response to […]

LARSEN, D.A.*; COOPER, K.A.; SHIMIZU, M.; National Marine Fisheries Service, Seattle, WA.: In vivo effects of testosterone and 11-ketotestosterone on the GH-IGF-I axis (plasma GH, IGF-I, and putative IGFBP-3) in coho salmon, Oncorhynchus kisutch. Studies in fish have demonstrated significant interactions among the endocrine factors regulating growth and reproduction including stimulatory and inhibitory effects of […]

DICKHOFF, W.W.; Northwest Fisheries Science Center, Seattle; Univ. Washington, Seattle: ENDOCRINE CONTROL OF GROWTH IN VERTEBRATES: AN ALTERNATE VIEW The conventional view of endocrine control of vertebrate growth is the growth hormone-insulin-like growth factor axis (GH-IGF axis). Operation of the axis is usually described in the sequence of pituitary GH stimulating production of IGF, and […]

MIGLIETTA , M.P.; SCHUCHERT , P.; Duke University; Mus�um d’histoire naturelle, Gen�ve , Switzerland: The Phylogeny of the genus Turritopsis (Hydrozoa – Cnidaria)-The immortal jellyfish The ability to revert its life cycle, thus becoming potentially immortal, brought some unexpected fame to the otherwise inconspicuous jellyfish genus Turritopsis. The process of transdifferentiation enables the jellyfish to […]

HALANYCH, K. M.; PASSAMANECK, Y.; Auburn Univ.; Woods Hole Oceanographic Insitution: Recent Progress on Resolving Lophotrochozoan Phylogeny The Lophotrochozoa, including mollusks, annelids, brachiopods, flatworms and their allies, encompasses the greatest amount of body plan diversity of the three major bilaterian lineages. Within the clade interphyletic relationships are poorly resolved with most previous analyses limited to […]

HARMON, M.C. *; GAREY, J.R.; LIVINGSTON, B.T.; University of South Florida, Tampa; USF, Tampa; USF, Tampa: Position of the Ophiuroids within the Echinodermata Revisited Both the ribosomal RNA gene sequences and the informative morphological characters within the Echinodermata have proven phylogenetically inconclusive with regards to the position of the ophiuroids. Littlewood et. al. report in […]

In the phylum Placozoa, only two species have been described, Trichoplax adhaerens Schulze (1883) and Treptoplax reptans Monticelli (1893). Whereas the former has […]

CAMPBELL, T.G.*; GAREY, J.R.; University of South Florida: Phylogenetic Analysis of the Micrognathozoan, Limnognathia maerski, Based on the 18S rRNA Gene Micrognathozoans were first discovered in 1994 by Reinhardt Kristensen and Peter Funch after an analysis of the meiofauna of a cold freshwater spring on Disko Island, Greenland. The only described micrognathozoan species, Limnognathia maerski, […]

STRUCK, TORSTEN H*; WESTHEIDE, WILFRIED; PURSCHKE, G�NTER; Auburn University, AL; Universit�t Osnabr�ck, Germany; Universit�t Osnabr�ck, Germany: Origin of new species by sexual maturity in larval stages � Progenesis in polychaetes (Annelida) The origin of species is among the most discussed, but least understood processes of biological evolution. One possible mechanism is progenetic evolution of small […]
