What's the difference between trematode and vitellogene?
Trematode
Definition:

Example Sentences:

(11) A study of the ultrafine structure, hysto- and biochemistry of trematodes will enable us to associate better the morphology and the function of organs and to go deeper into the functional morphology and functional biochemistry.
(12) The possession of common antigens by three trematode parasites which commonly occur together in ruminants in the tropics, Fasciola gigantica, Dicrocoelium hospes and Schistosoma bovis was studied in relation to the reliability of serodiagnosis of infection with these helminths.
(13) Infection or immunization with subcellular antigens of Fasciola hepatica confers high levels of immunity to a challenge infection with another trematode, Schistosoma mansoni.
(14) In vitro studies with Paramphistomum microbothrium indicated that the trematode is capable of synthesizing its complex lipids using exogenous substrates.
(15) These studies are revealing additional sites in trematodes that may be important for the development of new and more selective chemotherapeutic agents.
(16) In some trematodes, the caeca, especially in the brush border, and the tegument, subtegumental cells and testes, were reactive to the enzymes.
(17) New hosts are presented for the nematodes Cucullanus pinnai, Spirocamallanus inopinatus and Travnema travnema, for the trematode Pararhipidocotyle jeffersoni and for the acanthocephalan Gorytocephalus spectabilis.
(18) Further investigations are necessary to identify the species of this trematode and to understand if it is a true human parasite or a pseudoparasite.
(19) Trematodes found in 10 Numenius americanus from the Galveston area included Pelmatostomum americanum sp.
(20) Surgical repair of an inguinal hernia in a 19-year-old man in Honduras revealed massive numbers of small granulomata containing trematode eggs on the omentum and other peritoneal surfaces.
Vitellogene
Definition:
(n.) A gland secreting the yolk of the eggs in trematodes, turbellarians, and some other helminths.
Example Sentences:
(1) Significant changes in cytosolic and nuclear hepatic estrogen receptor levels correlate with vitellogenic stage.
(2) The vitellogenic response was assessed by measuring the distribution of the 32P radioactivity between the acidoprecipitable plasma fraction and the plasma vitellogenin recognized by the lizard antivitellogenin serum.
(3) The cephalic signal can be superseded by juvenile hormone, whose presence is necessary for each follicle to become vitellogenic.
(4) The numbers of vitellogenic oocytes in the ovary during the entire study also suggested that atresia of vitellogenic oocytes does not play a prominent role in determining fecundity.
(5) During vitellogenesis oocytes change widely in their shape, size and cytological organisation and their developmental stages can be divided into pre-vitellogenic, early-vitellogenic, vitellogenic, late-vitellogenic and maturation age.
(6) The fates of purified 32P-vitellin and 32P-lipophorin were followed in vitellogenic females of Rhodnius prolixus.
(7) The pituitaries of vitellogenic sockeye salmon (Oncorhynchus nerka) were extracted with a mixture of acetone, water, and hydrochloric acid.
(8) Analytical ultracentrifugal analyses of vitellogenic female HDL3 revealed the presence of two types of lipoproteins.
(9) It is the first clear evidence that pyriform cells and the oocyte may fulfill similar vitellogenic functions.
(10) Cuticular hydrocarbons subsequently fall, along with the disappearance of hemolymphatic ecdysteroids, and then rise again during the vitellogenic phase of JH production.
(11) vitellogenic and post-vitellogenic phases of its annual reproductive cycle.
(12) Vitellogenic proteins are present only in the yolk granules and near the theca cell layer as is shown by immunocytochemical methods.
(13) The above findings suggest that the development of the first clutch of vitellogenic follicles in the lizard utilises lipids stored in the fat bodies and that the growth of the subsequent clutches of vitellogenic follicles is met through the intake of food, which is abundant in the latter part of the breeding phase.
(14) Electrophoresis in SDS-polyacrylamide gels revealed three major apolipoproteins common to egg and vitellogenic HDL3.
(15) The reproductive performance of these females can be predicted approximately by the number of late vitellogenic oocytes present in their ovaries.
(16) Follicle cell nuclei are taken into the ooplasm of pre-vitellogenic follicles; they are finally absorbed before yolk deposition starts.
(17) Ovarian diapause is terminated at 12 degrees LD 10:14 in 7 days following topical application of either JH III or JHB3 at a concentration of about 0.5 micrograms per fly, diapause termination being expressed by an increased rate of vitellogenesis and by an increase in the number of fully developed eggs per vitellogenic female.
(18) The protein bodies appear first in the interfollicular spaces and towards the periphery of the oocytes just near the enveloping follicular epithelial cells, during the early-vitellogenic stage suggesting the formation of yolk proteins from the haemolymph.
