A schistosome [beta] subunit remodels inactivation of a calcium channel _via_ an N-terminal polyacidic motif [PDF]
, 2010 The beta subunit of high voltage-activated Ca (Cav) channels targets the pore forming [alpha]~1~ subunit to the plasma membrane and defines the biophysical phenotype of the Cav channel complex. Cav channel inactivation following activation and opening is

Fish Space Use and Behavior in an Aquarium: The Use of Microhabitats as Enrichment
Zoo Biology, EarlyView.The inclusion of microhabitats in a stream tank serves as environmental enrichment for fish in human care. ABSTRACT Environmental enrichment is an important tool to maintain the health and well‐being of animals in human care, but studies of environmental enrichment for fish in human care have lagged behind those of land animals.

Characterization of schistosome tegumental alkaline phosphatase (SmAP).
PLoS Neglected Tropical Diseases, 2011 Schistosomes are parasitic platyhelminths that currently infect over 200 million people globally. The parasites can live for years in a putatively hostile environment - the blood of vertebrates. We have hypothesized that the unusual schistosome tegument (

The Embryonic Development of the Cotylean Polyclad Phrikoceros jannetae
Acta Zoologica, EarlyView.ABSTRACT Polyclads exhibit distinct developmental modes ranging from direct to indirect development, with several transitional stages also recognised. The existence of an indirect developmental mode in polyclads with a planktonic life history stage in the form of a free‐swimming larva is unique among all free‐living flatworms and makes polyclads a ...
