Disease relevance of Oviposition

• After oviposition, CD4(+), CD8(+), and CD19(+) splenocytes and granuloma cells expressed elevated levels of FasL but FasL expression declined during the downmodulated stage of infection [1].
• In group B (fipronil 1%), 66 animals showed C. hominivorax eggs, with 92 ovipositions and five animals with active myiasis [2].
• Here we report on increased levels of TNF-alpha and its soluble receptors in murine schistosomiasis, beginning with schistosome oviposition and circumoval granuloma formation [3].
• The role of urea in the oviposition behaviour of Japanese encephalitis vectors in rice fields of South India [4].
• Suppression of leaf feeding and oviposition of phytophagous ladybird beetles (Coleoptera: Coccinellidae) by chitinase gene-transformed phylloplane bacteria and their specific bacteriophages entrapped in alginate gel beads [5].

Psychiatry related information on Oviposition

• Sex-peptide (SP), which is secreted by the accessory gland of Drosophila males, is transferred to the female during copulation, thereby reducing her sexual appetite (receptivity to males) and stimulating ovulation/oviposition [6].

High impact information on Oviposition

• Embryonic synthesis of histone mRNA begins at 90 min after oviposition, making the histone genes among the first to be transcribed by embryonic nuclei [7].
• Three compounds (cis-3-hexen-1-ol, linalool, and cis-alpha-bergamotene) increased egg predation rates by a generalist predator; linalool and the complete blend decreased lepidopteran oviposition rates [8].
• For successful parasitization, the female Campoletis sonorensis endoparasitic wasp injects a polydnavirus into its host, Heliothis virescens, during oviposition [9].
• Since juvenile hormone analogue does not elicit increased oviposition and reduced receptivity, Sex-Peptide must have an additional, separate effect on these two postmating responses [10].
• Feeding 20-hydroxyecdysone at 94 hr after oviposition allows giant larvae to develop at the same rate as wild-type larvae and to produce normal-sized adults (although at 94 hr the imaginal discs of giant lack much of the folding pattern of mature discs) [11].

Biological context of Oviposition

• It is well established that avian oviposition is regulated, at least partly, by a neurohypophysial hormone, arginine vasotocin, and ovarian hormones, prostaglandins, are regulated through mechanisms of the induction of uterine contractions [12].
• Plasma levels of 13,14-dihydro-15-keto prostaglandin F2 alpha in relation to oviposition and ovulation in the domestic hen (Gallus domesticus) [13].
• Moreover, these findings clearly indicate temporal correlation of AVT and its receptor gene expression in different tissues during oviposition [14].
• Oogenesis and oviposition were otherwise unaffected, also suggesting that precocene affects the gland cells directly, rather than indirectly by antagonism of juvenile hormone [15].
• Circadian rhythms of oviposition and feeding activity in Japanese quail: effects of cyclic administration of melatonin [16].

Anatomical context of Oviposition

• These results suggest that avian galanin in the oviduct evokes oviposition through mechanisms of the induction of uterine and vaginal contractions [12].
• None of these stimuli enhanced the already high output of PGF2 alpha when added to incubations of granulosa cells collected within 5 min after oviposition [17].
• One of these proteins, early-expressed protein 1 (EP1), is a 190-kDa molecule which constitutes up to 5% of the total hemolymph protein by 24 hr following oviposition by the wasp [18].
• Appearance of an arginine vasotocin receptor of large molecular size in the uterus (shell gland) of the hen at oviposition [19].
• In the control group the concentration of AVT decreased in the neurohypophysis and increased in plasma at oviposition [20].

Associations of Oviposition with chemical compounds

• On the other hand, the injection of pharmacological doses of melatonin into 2-day-old female flies diminishes the mating speed and the oviposition rate [21].
• In both situations, dexamethasone had no effect on the parasite burden but altered the egg distribution in tissue, indicating that under the schedule used it did not interfere with the development of adult worms or oviposition [22].
• Progesterone titers remained low throughout egg retention and oviposition [23].
• The concentration of PGFM in plasma from the brachial vein increased at midsequence oviposition, while the levels of PGE2 were unchanged [24].
• In contrast, the concentration of PGF2 alpha did not increase during the 12-h period preceding the terminal oviposition of the sequence in plasma from the brachial, uterine, or follicular veins.(ABSTRACT TRUNCATED AT 250 WORDS)[24]

Gene context of Oviposition

• It was shown that attainment of a definite JHE activity level in females of lines 101 and 147 agrees well with the onset of oviposition of fertilized eggs [25].
• Using null and antimorphic mutants to show decreased walking ability and delayed/reduced oviposition we demonstrated that Act88F expression is functionally important in multiple muscle groups [26].
• Logjam encodes a predicted EMP24/GP25 protein that is required for Drosophila oviposition behavior [27].
• In addition, we have used available data on Yolk Protein electrophoretic pattern and jousting, oviposition, and mating behavioral characters [28].
• The development of a sensitive detection assay based on a chemiluminescent substrate for beta-galactosidase allowed us to determine the onset of DmRP140 transcription to between 8-10 h after oviposition [29].

Analytical, diagnostic and therapeutic context of Oviposition

• The effect of active and passive immunization against testosterone on ovarian follicular development and oviposition was studied [30].
• In contrast, topical or oral administration of captopril to newly emerged adults caused a reduction in oviposition [31].
• Plasma 13,14-dihydro-15-keto prostaglandin F2alpha (PGFM) and progesterone levels were determined in actively ovulating, 1- to 2-yr-old female geese (Anser anser domesticus) at hourly intervals during the oviposition cycle, using the enzyme immunoassay (EIA) technique [32].
• 4. Intravenous injection with arginine vasotocin or prostaglandins also induced oviposition and pigment secretion; indomethacin, however, only inhibited pigment secretion [33].
• Bioassays with individual compounds showed that only 3-methylindole consistently induced oviposition, in concentrations spanning 5 orders of magnitude [34].
