What's the difference between excessive and superfetation?
Excessive
Definition:
(a.) Characterized by, or exhibiting, excess; overmuch.
Example Sentences:
(1) 5-Azacytidine (I) stability was increased approximately 10-fold over its stability in water or lactated Ringer injection by the addition of excess sodium bisulfite and the maintenance of pH approximately 2.5.
(2) Since the advance and return of sperm inside the tubes could facilitate the interaction of sperm with secretions participating in its maturation, the persistent infertility after vasectomy could be related to the contractile alteration that follows the excessive tubal distention.
(3) The following conclusions emerge: (i) when the 3' or the 3' penultimate base of the oligonucleotide mismatched an allele, no amplification product could be detected; (ii) when the mismatches were 3 and 4 bases from the 3' end of the primer, differential amplification was still observed, but only at certain concentrations of magnesium chloride; (iii) the mismatched allele can be detected in the presence of a 40-fold excess of the matched allele; (iv) primers as short as 13 nucleotides were effective; and (v) the specificity of the amplification could be overwhelmed by greatly increasing the concentration of target DNA.
(4) Excessive lip protrusion was eliminated, and arch leveled.
(5) Ten milliliters of the solution inappropriately came into contact with nasal mucous membranes, causing excessive drug absorption.
(6) Dietary factors affect intestinal P450s markedly--iron restriction rapidly decreased intestinal P450 to beneath detectable values; selenium deficiency acted similarly but was less effective; Brussels sprouts increased intestinal AHH activity 9.8-fold, ECOD activity 3.2-fold, and P450 1.9-fold; fried meat and dietary fat significantly increased intestinal EROD activity; a vitamin A-deficient diet increased, and a vitamin A-rich diet decreased intestinal P450 activities; and excess cholesterol in the diet increased intestinal P450 activity.
(7) Cigarette consumption has also been greater in urban areas, but it is difficult to estimate how much of the excess it can account for.
(8) Preliminary studies of different systems suggest several of them may have sensitivity to detect intraepithelial abnormalities in excess of 95%.
(9) Excessive accumulation of hydrogen ions in the brain may play a pivotal role in initiating the necrosis seen in infarction and following hyperglycemic augmentation of ischemic brain damage.
(10) Fifty-four cases were analysed, and a two-fold excess of clustering within one year was observed, both within single districts and between adjacent districts.
(11) The first one is a region with iodine insufficiency; the second one is a region where the people use table salt in excess.
(12) Addition of methacholine to the substance-P-treated cells caused a rapid increase in [3H]IP3, whereas a second addition of a 10-fold excess of substance P had no effect.
(13) It is possible that the marked elevations in obsessive-compulsive symptomatology and in interpersonal sensitivity may reflect in part a sensitization to excessive performance demands.
(14) Using the intersection point of these pH-logPCO2 lines as a point of equal hemoglobin-independent "base excess" for each condition, values for true base excess were plotted.
(15) This excess in diagnosis comprises, in particular, the ductal type, primarily its most aggressive forms.
(16) Attention is drawn to the desirability of differentiating between supra- and sub-gingival calculus in the CPITN scoring system and to the excessive treatment requirements that arise from classifying everyone with calculus as requiring prophylaxis and scaling.
(17) IgG-gold also adhered to M cells and excess unlabeled IgG inhibited IgA-gold binding; thus binding was not isotype-specific.
(18) The technique did not compromise cancer resection, excessively prolong operating time, or alter postoperative management.
(19) The temperature-activated 4 to 5 S EBP transformation is found to be highly reproducible without loss of [3H]estradiol-binding activity in a buffer containing an excess of [3H]estradiol, 40 mM Tris, 1 mM dithiothreitol, and 1 M urea at pH 7.4.
(20) The amount of cleavage products depends on the excess of H2O2 used.
Superfetation
Definition:
(n.) The formation of a fetus at the result of an impregnation occurring after another impregnation but before the birth of the offspring produced by it. This is possible only when there is a double uterus, or where menstruation persists up to the time of the second impregnation.
Example Sentences:
(1) Combined pregnancies rarely occur without treatment with ovulation inducing agents by superfecundation and superfetation.
(2) Suspected superfetation was investigated in a Glasgow hybrid stock of mice.
(3) Intervals between successive deliveries that are shorter than the normal duration of gestation do not necessarily indicate superfetation and this phenomenon may be rare among hares in captivity as well as in the wild.
(4) A frequent explanation was that twins were the result of superfetation, a divine impregnation occurring along with that by the lawful husband.
(5) Those phases reviewed include ovulation, fertilization and tubal passage of sperm and fertilized ova, capacitation of spermatozoa, the spacing of ova along the uterus, preimplantation stages of the uterus and uterus-blastocyst interaction, decidualization, the zona pellucida, normal and delayed nidation, superfetation, and the parthogenetic activation of eggs.
(6) This observation reports a case of human superfetation.
(7) The possibility of inducing superfetation in hares by artificial insemination (AI) was investigated.
(8) Ovulation during pregnancy is hypothesized to be the cause of superfetation found in mares.
(9) The second gestation was of normal length and superfetation was not therefore considered to be the cause of the anomalous litters.
(10) In humans, superfetation has been recorded secondary to ovulation induced by clomiphene citrate.
(11) This case report should support earlier evidence that superfetation in the bovine can and does occur.
