Helminth

(11) In addition, a number of antiparasitic agents have been shown to exert their actions through a free radical metabolism: nitro compounds used against trypanosomatids, anaerobic protozoa and helminths; crystal violet used in blood banks to prevent blood transmission of Chagas' disease; the antimalarial primaquine, chloroquinine, and quinhasou; and quinones active in vitro and in vivo against different parasites.
(12) Results of the infection of golden hamsters with different dozes of cercariae have shown that with the increase of dozes of infectious material the infection rate of helminths rises during the experimental intestinal schistosomiasis only to a definite level, which is attained by the injection of cercariae into the portal vein in dozes lower than those used for subcutaneous infection.

(17) Levamisole and Banminth affected the motility of the helminth larvae with subsequent death after 24h.
(18) A significant association was also found between distance from a river and prevalence of S. haematobium (r = 0.94) and S. mansoni (r = 0.95) (P less than 0.01), but not with the other helminth infections.
(19) In addition to the known human pathogenic helminths H. nana and H. diminuta, localized foci of hookworms (Ancylostoma spp.)
(20) The observation, in parasitic protozoa and helminths, that selfing or non-obligatory mating is a common feature suggests that these processes may be strategies to overcome the cost of meiosis.
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(3) The cephalic signal can be superseded by juvenile hormone, whose presence is necessary for each follicle to become vitellogenic.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.
