(1) A tentative yet comprehensive review of the effects of smoking on reproductive capacity includes conception, sperm morphology, teratogeny and intrauterine growth retardation, cancer, timing of menopause, estrogen secretion, in vitro fertilization and estrogen metabolism.
Teratology
Definition:
(n.) That branch of biological science which treats of monstrosities, malformations, or deviations from the normal type of structure, either in plants or animals.
(n.) Affectation of sublimity; bombast.
Example Sentences:
(1) The importance of precocious development for planning teratological studies is emphasized.
(2) Unlike previous studies with 13-cis-retinoic acid during the pre- and early organogenic stages of development (Hummler et al., Teratology 42:263-272, 1990), no thymic hypo- or aplasia or heart anomalies were observed, which may be attributable to the slightly longer 13-cis retinoic acid treatment period, i.e., GD 10-27.
(3) It seems likely that diaphragmatic hernia is a non-specific consequence of several teratological processes.
(4) The principles of teratology are described, and animal models for research in abnormal ocular development and clinical studies of human teratogens are surveyed.
(5) Functional teratology is quite a new concept in neuroscience.
(6) Dams were killed on Day 19 and the fetuses were assessed for teratologic anomalies.
(7) On the basis of findings published in the literature, morphologic changes seen among the author's patients were classified as anthropologic and teratologic dislocations.
(8) The synthesis of these sciences into the relatively nascent science of reproductive toxicology includes teratology, pharmacology, epidemiology, and occupational and environmental health.
(9) In 1652, a chair of anatomy was created; embryology and teratology, at that time solely morphological sciences, depended on anatomy.
(10) No teratological or abortifacient effects were noted.
(11) The elaboration of the effect of retinoic acid on limb morphogenesis has prompted renewed investigation into the teratology of retinoic acid treatment, with the hope that such analysis might give insight into mechanisms of vertebrate patterning.
(12) The first generation (F0) gilts were bred after 4 months of study; some were killed for teratologic assays at 100 days of gestation (dg), and the others produced an F1 generation of offspring.
(13) The results are discussed with particular reference to the evaluation of teratologic studies on food colouring in general and the various regulation proposals from the National Food Administration.
(14) It also illustrates that selected histochemical studies may be helpful in a teratologic investigation.
(15) Subtle functional disturbances in organisms exposed while immature (behavioral teratology) may be one of the most sensitive indicators of chemical toxicity.
(16) N-Ethyl-N-nitrosourea (ENU) was administered intravenously to pregnant Wistar-albino rats on days 14--21 of gestation in order to study the teratological effects of the carcinogen on the developing brain.
(17) Concerning the applied doses no teratological effect was observed.
(18) The developmental toxicity of acetonitrile and 5 halogenated derivatives was examined with an in vivo teratology screen adapted for use in the Long-Evans rat.
(19) A wealth of literature has become available about lasting functional consequences of perinatal psychotropic drug exposure, having affected brain development in a subtle rather than gross structural way (behavioral teratology or functional neuroteratology).
(20) It is suggested that teratological investigations be carried out on the basis of a clearly formulated problem using experimental procedures suited to the biological characteristics of the test substances and of the animals.
