What's the difference between multiparous and polytocous?
Multiparous
Definition:
(a.) Producing many, or more than one, at a birth.
Example Sentences:
(1) There were 49% primiparous and 51% multiparous women.
(2) The incidence of grand multiparity was only 4.7%; however, 25% were less than 30 years old.
(3) Ninety multiparous Holstein cows were used to determine the effect of ration energy density and bST on lactation performance and whole body chemical composition.
(4) The problem of a pregnancy with a prior cesarean section is an ever-increasing one and, in our practice, approximately 25% of multiparous patients have had a prior cesarean delivery.
(5) Fewer multiparous cows given two injections 14 d apart and inseminated after estrus conceived than did cows given two injections and a progesterone intravaginal coil inserted 8 d after the first injection (42 vs. 66%).
(6) An interaction was found between race and maternal age and between multiparity and type of hospital of birth.
(7) An MLC reaction inhibiting serum from a grand-multiparous woman (16 successful pregnancies) is described.
(8) The increased incidence of gallstones in multiparous women may be related to hormonal effects on the gallbladder and its contractility.
(9) The cessation of regular cyclicity during aging occurred significantly (p less than 0.01) earlier in virgin than multiparous rats.
(10) Two cytotoxic human-human hybridoma IgM antibodies to HLA were generated by EBV transformation of PBMC from multiparous women and fusion of EBV transformed cells with the human fusion partners KR4 or KR12.
(11) It has previously been shown that J.H., a human leukocyte antigen (HLA)-Dw2 homozygous multiparous woman, fails to respond in a mixed lymphocyte reaction (MLR) to her Dw1 homozygous husband W.H., and that her T cells suppress the responses of HLA matched responders to W.H.
(12) The litter sizes of 8- to 10-mo-old primiparous females were not different from those of multiparous rats.
(13) Multiparity and twin pregnancies are predisposing factors.
(14) In the first-litter sows lower serum levels were found for all three Ig classes as compared to multiparous sows.
(15) The majority of patients are multipare between 28 and 47 years old.
(16) Both patients are elderly multiparous females with long-standing peripheral venous disease and a history of previous gynaecologic surgery.
(17) Adherence inhibition was not observed when PC from tumor-immunized or multiparous mice were exposed to antigen extracts from adult syngeneic livers or kidneys.
(18) Logistic regression analyses of the multiparous and nulliparous populations showed independent sets of significant (p less than or equal to 0.05) risk variables.
(19) Indications were multiparity, previous caesarean section and socioeconomic reasons.
(20) Sixty percent of the mothers smoked and 50% had other identifiable risk factors for preterm delivery; 20% of the multiparous patients had previously experienced a perinatal death, preterm delivery or had a baby with intra-uterine growth retardation.
Polytocous
Definition:
(a.) Bearing fruit repeatedly, as most perennial plants; polycarpic.
(a.) Producing many or young.
Example Sentences:
(1) In polytocous species, animals with reduced birth weights are associated with reduced neonatal survival, which may be related to substandard placental function.
(2) This is particularly true for polytocous species, where it may be necessary to achieve some regulation of litter size by differential embryonic mortality.
(3) In the rat, as in most other polytocous species, fetuses tend to be relatively evenly spaced along the uterine horn, perhaps to minimize possible effects of local overcrowding on placental function and fetal growth.
(4) The pig is an excellent animal in which to study the control of folliculogenesis in a polytocous species, and particularly to examine the inter-relationships between follicles from the same animal.
(5) Although the rat is a polytocous rodent, the female has a regular ovarian cyclicity of 4 or 5 days, with distinct proestrus, estrus, and diestrus phases.
(6) A special problem in prenatal toxicity is the inter- and intralitter variability of the toxic manifestation (especially in polytocal animals).
(7) We examined whether or not the sex of the fetuses of polytocous animals distributes randomly in the position along the uterine horn in 255 mouse litters.
(8) This procedure is pertinent especially for polytocous species such as swine and poultry, for which the occurrence of full-sib families makes the inclusion of dam effects in the model necessary and tests are completed throughout the year.
(9) This model is unique in that atresia can be induced in the single DF of a primate species, and thus avoids the disadvantages inherent to studying atresia of heterogeneous follicles in polytocous species.
(10) This procedure, specific for a hierarchical portion of a model relevant to many animal breeding populations, is pertinent especially for polytocous species such as swine and poultry.
