Schistosoma mansoni : use of a fluorescent indicator to detect nitric oxide and related species in living parasites
Nitric oxide (NO) is synthesized enzymatically by nitric oxide synthase (NOS). Several groups have previously presented evidence for NOS activity and immunoreactivity in several parasitic platyhelminths, including ...
uBioRSS : tracking taxonomic literature using RSS
(Oxford University Press, 2007-03-28)
Web content syndication through standard formats such as RSS and ATOM has become an increasingly popular mechanism for publishers, news sources, and blogs to disseminate regularly updated content. These standardized ...
Is science as global as we think?
A cornerstone of scientific practice is the perceived freedom with which knowledge is disseminated. But does the scientific community make good use of all that is available? Researchers have, on occasion, been accused of ...
Voltage-gated calcium channel subunits from platyhelminths : potential role in praziquantel action
Voltage-gated calcium (Ca2+) channels provide the pathway for Ca2+ influxes that underlie Ca2+-dependent responses in muscles, nerves, and other excitable cells. They are also targets of a wide variety of drugs and toxins. ...
Proteins of the glycine decarboxylase complex in the Hydrogenosome of Trichomonas vaginalis
(American Society for Microbiology, 2006-12)
Trichomonas vaginalis is a unicellular eukaryote that lacks mitochondria and contains a specialized organelle, the hydrogenosome, involved in carbohydrate metabolism and iron-sulfur cluster assembly. We report the ...
Two families of non-LTR retrotransposons, Syrinx and Daphne, from the Darwinulid ostracod, Darwinula stevensoni
Two novel families of non-LTR retrotransposons, named Syrinx and Daphne, were cloned and characterized in a putative ancient asexual ostracod Darwinula stevensoni. Phylogenetic analysis reveals that Daphne is the founding ...
Quantitative orientation-independent differential interference contrast (DIC) microscopy coupled with orientation-independent Polarization microscopy
(Cambridge University Press, 2007-08-05)
Differential interference contrast (DIC) microscopy is widely used to observe structure and motion in unstained, transparent living cells and isolated organelles, producing a monochromatic shadowcast image of optical ...
Time lapse movie of meiosis II in a living spermatocyte from the crane fly, Nephrotoma suturalis, viewed with polarized light microscopy
The events of meiosis II in two living spermatocytes obtained from the testis of a crane-fly larva are recorded in this time-lapse sequence beginning at prophase II through telophase II to the near completion of cytokinesis ...
Characterization of EST derived SSRs from the bay scallop, Argopecten irradians
Interest in bay scallop conservation has resulted in organized stock enhancement efforts and increased attention to fisheries management issues. Genetic markers can facilitate the monitoring of enhancement efforts, ...
