(v. i.) To give an example.
(1) Would people feel differently about it if, for instance, it happened on Boxing Day or Christmas Eve?
(2) In both instances the permeation rates of proteins can be better correlated to hydrodynamic radii than to molecular weights.
(3) In three instances SAA levels increased during hospitalization while CRP levels did not.
(4) A 6.4 kilobase C4B-5'-specific Taq I fragment usually provided a reliable guide to the presence of a C4A deletion but unusually in one instance this fragment was found to be a marker of a functioning C4A gene.
(5) "Runners, for instance, need a high level of running economy, which comes from skill acquisition and putting in the miles," says Scrivener, "But they could effectively ease off the long runs and reduce the overall mileage by introducing Tabata training.
(6) Both hypodontia and hyperdontia are found in a number of well-defined genetic syndromes and in most instances are common characteristics of the disease.
(7) The opportunities for infection are often strong in areas of high population within a city – schools, for instance.
(8) Of these, 12 had radiation-induced neurologic complications which, in 5 instances, consisted of persisting, wholly or partially disabling paresis in the lower limbs.
(9) The decision of the editors to solicit a review for the Medical Progress series of this journal devoted to current concepts of the renal handling of salt and water is sound in that this important topic in kidney physiology has recently been the object of a number of new, exciting and, in some instances, quite unexpected insights into the mechanisms governing sodium excretion.
(10) We firmly believe that a systematic approach to the 12-lead ECG can provide information that can diagnose the difference between ventricular and supraventricular tachycardia, and in many instances diagnose the mechanism and site of origin of the supraventricular tachycardia.
(11) Other less common indications are some instances of aspiration pneumonia, septicemias due to B. fragilis, and actinomycoses.
(12) Tension in flexor tendons during wrist flexion may play a role in otherwise unexplained instances of the carpal tunnel syndrome.
(13) But most instances are more mundane: the majority of fraud cases in recent years have emerged from scientists either falsifying images – deliberately mislabelling scans and micrographs – or fabricating or altering their recorded data.
(14) The right side of the ventricular septum was affected in five instances.
(15) Women on the beat: how to get more female police officers around the world Read more Mortars were, for instance, used on 5 June when Afghan national army soldiers accidentally hit a wedding party on the outskirts of Ghazni, killing eight children.
(16) Our own experiences have shown that patients involved in studies with well designed protocols are better controlled and in most instances also better treated than patients treated outside such protocols.
(17) No instances of osteoradionecrosis occurred as a result of dental extraction with this conservative method.
(18) Therefore these suggested methods of choice may not in every instance be the most accurate of all indicators of nutritional status for a particular nutrient.
(19) The advantage of this in vivo method is the possibility to determine the thyroidal activity at various times after 131I-application (2 phase test) and by repeated 131I-applications under different conditions (diet, age, for instance).
(20) In each instance, dexamethasone was given at midnight and the plasma ACTH concentration was determined at 9:00 a.m. on the day before and after administration of the dexamethasone.
(n.) The production of new individuals from virgin females by means of ova which have the power of developing without the intervention of the male element; the production, without fertilization, of cells capable of germination. It is one of the phenomena of alternate generation. Cf. Heterogamy, and Metagenesis.
(n.) The production of seed without fertilization, believed to occur through the nonsexual formation of an embryo extraneous to the embrionic vesicle.
(1) O. puertoricensis did not exhibit autogeny or parthenogenesis.
(2) Cyclical parthenogenesis exaggerates the force of selection relative to recombination and will therefore enhance interlocus effects.
(3) Fertilization anomalies (possibly increased by in vitro procedures) were recorded: 1.6% of embryos resulted from parthenogenesis and 6.4% were polyploid (mainly polyspermic).
(4) Now, productive colonies of these lizards, which have remarkably little genetic variation, can be readily established and used not only for research on parthenogenesis but also for many kinds of experiments for which reptile systems are desirable.
(5) This rapid and extensive range expansion provides strong evidence that parthenogenesis can be a successful strategy for lizards in an environment with low and unpredictable rainfall.
(6) We used a comparison between cleavage rates and fertilization rates according to chromosomal analysis of oocytes to estimate the parthenogenesis frequency.
(7) These populations are thus panmictic, and most likely reproduce by cyclical parthenogenesis.
(8) Rickettsia-like maternally inherited bacteria have been shown to be involved in a variety of alterations of arthropod sexuality, such as female-biased sex ratios, parthenogenesis, and sterility of crosses either between infected males and uninfected females or between infected individuals (cytoplasmic incompatibility).
(9) There was no significant difference in parthenogenesis between any of the culture media and it appears to be a function of the strain of mice and the timing between human chorionic gonadotropin (hCG) injection and ovum collection.
(10) Parthenogenesis frequency was increased by male sexual rest.
(11) The causes for the variability of parthenogenesis indices in the polyploid clones are discussed.
(12) In vitro fertilization enabled the study of lethal (parthenogenesis) or sublethal (triploidy, monosomy and trisomy) chromosomal abnormalities in man.
(13) Methylamine appeared to activate oocytes, and most of them developed by haploid parthenogenesis.
(14) It is suggested that males are heteromorphic for the long homologue due to chromatin diminution, that occurs in the maturation division of mitotic parthenogenesis.
(15) A time-course experiment demonstrated that the extent of parthenogenetic activation in vivo following Br treatment was related to the period of time between drug injection and isolation of ova, the optimal period being 12 h. Neither Br nor MA had a direct activating effect on the oocytes as evidenced by an inability to induce parthenogenesis in vitro.
(16) Since calf thymocyte centrosomes do not support parthenogenesis, the present results suggest that duplication of the foreign centrosome is required for centrosome-induced parthenogenesis.
(17) The oocytes were prepared by a combined enzyme-mechanical method without impairing the fertility of the oocyte or inducing parthenogenesis.
(18) Comparisons are made with previously published models that deal with monogamous mating and with parthenogenesis.
(19) Parthenogenesis can only evolve in areas devoid of the generating bisexual species, because such species would prevent newly formed unisexuals from establishing clones due either to hybridization or competition.
(20) The evolutionary switch from paternal to maternal inheritance in mammals might be related to the additional dangers that parthenogenesis represents: a threat to the life of the mother as well as to the life of the fetus.
