241 As planned, 0.2 million embryos, 13 thousand internal embryos, 7000 preternaturally and collect ovum produced embryos will be produced annually when the project finished.

242 The results are as follows: (1) The mitochondria in the embryos before morula stage were mostly hooded.

243 But such experiments destroy human embryos, so right - to - lifers object.

244 The virus could not agglutinate 1% of the chicken erythrocytes and interfered with the development of the hemagglutinins by the B-1 strain of Newcastle disease virus in the chicken embryos.

245 Objective:To probe into the synergetic teratogenic action on mouce embryos between hyperthermia and observed factors (Vitamin A and dactinomycin).

246 The purpose of this study is to increase the pregnancy rate in patients with implantation failure by use of a co-culture system for human embryos development on autologous endometria monolayer cells.

247 Bush has restricted the use of cloned human embryos in research.

248 Objective To investigate the effect of environmental contaminants on development rate and DNA methyltransferase activity of preimplantation embryos.

249 The cells of the integument and nucellus of some plants form perfectly normal embryos.

250 In this study, the foreign gene was transferred into wheat immature embryos by Agrobacterium tumefaciens mediated, and the factors influencing wheat transformation were analyzed.

251 In contrast to Haeckel's drawings, these photos show remarkable differences between the early embryos of these species.

252 Scientists have secretively created more than 150 human-animal hybrid embryos in British laboratories over the past three years.

253 The experimental results confirmed that photobacterium phosphoreum and zebrafish(B. Rerio)embryos were favourable to carry out combined toxicological experiment.

254 That's because "pregnant" pipefish fathers will kill off embryos conceived by an undesirable female to make room for the offspring of a potentially more attractive female.

255 However, the embryos at gastrula or heart beating stage were very sensitive to UV irradiation, showing just damage effect, which was very strong even at very low amount of the UV irradiation.

256 The term caudal means nearer to the tail and is used in description of embryos.

257 There are two methods of collecting cow embryos -- directly through the birth canal,(www.Sentencedict.com) or surgically.

258 In this paper, we have studied effects of monocrotophos on the development of preimplantation mouse embryos cultured in a simple defined chemical medium.

259 Cc, born two months ago, was the only live birth from 87 cloned embryos that were implanted in surrogate mothers.

260 By using the improved FHK apparatus made in Japan for embryo transfer in dairy cattle, the embryos were transferred into the uterine gland of two cattle recipients through the vaginal fornix.

261 Results: As the decreasing score of the oocyte, the maturation rate, fertilization rate, cleavage rate and the quality of embryos decreased, meanwhile the apoptosis rate of granulose cells increased.

262 A series of numerical experiments have been done to test the seeding effect of artificial icecristals or raindrop embryos using a one-dimentional time dependent cumulonimbus cloud model.

263 Working with iPS cells in this way also gives information that should make it easier to develop embryonic stem cells (ES cells) from pig or other ungulate embryos, said the researchers.

264 The effects of fetal bovine serum(FBS) addition time, concentration and different culture systems on the developmental potentiality of bovine parthenogenetic embryos were observed.

265 Objective To explore the method of embryos transplant technology in evaluating the development toxicity of hydroxyurea.
