摘要:
Processing and use of fluids from the reproductive tract (biofluids) to improve the in vitro production of mammalian embryos comprising the following steps: a) fractionation and processing of biofluids through a sorting, purification, lyophilization and subsequent storage; b) a method of sperm capacitation in a culture medium supplemented with biofluids; c) in vitro fertilization in a medium enriched with biofluids and d) subsequent in vitro culture with development of the obtained embryos to any stage of preimplantational development in culture media supplemented with biofluids.
摘要:
The present invention provides compositions and methods for detection schemes for ascertaining pregnancy status of an animal. The compositions and methods employ interferon-tau (IFNT) and/or antibodies specific for IFNT. Methods of the present invention detect the presence of IFNT in samples obtained from animals as an early indicator of pregnancy. Methods are provided to identify non-pregnant animals so that management decisions regarding rebreeding can be made earlier compared to existing approaches.
摘要:
The invention relates to a double-stranded ribonucleic acid (dsRNA) for inhibiting the expression of a RRM2 gene. The invention also relates to a pharmaceutical composition comprising the dsRNA or nucleic acid molecules or vectors encoding the same together with a pharmaceutically acceptable carrier; methods for treating diseases caused by the expression of a RRM2 gene using said pharmaceutical composition; and methods for inhibiting the expression of RRM2 in a cell.

摘要:
The present invention provides data to demonstrate that the fusion performance of a cell-line in procedures involving fusion and cleavage indices either alone or in combination are a means for selecting a cell lines that will be successful in a nuclear transfer or microinjection program. This technique and method of selecting a cell line offers an additional alternative and improvement in the creation of activated and fused nuclear transfer-capable embryos for the production of live offspring in various mammalian non-human species including goats, pigs, rodents, primates, rabbits and cattle.
摘要:
The present invention is directed to various methodologies to make NT a practical procedure for animals, specifically, primates including human and non-human primates. Furthermore, the methods and molecular components provided by the the present invention provide a practical means for producing embryos with desired characteristics. In a specific embodiment, the methodology of the present invention comprises introducing nuclei having desired characteristics along with one or more molecular components into an egg, culturing the egg to produce a viable embryo, transferring the embryo to the oviducts of a female, and prouducing a cloned animal.
摘要:
Est décrit un procédé pour induire un état anhydrobiotique chez les sujets jeunes infectieux des nématodes entomogènes. Ces sujets jeunes infectieux anhydrobiotiques se prêtent particulièrement au stockage et au transport. Ce procédé permet une dessiccation soigneusement contrôlée desdits sujets en les mettant en suspension dans de l'huile, et en éliminant graduellement l'eau à l'aide d'un agent déshydratant, notamment en utilisant de l'air à une humidité relative inférieure à 100 %, en présence éventuelle d'un tensio-actif.
摘要:
Modified Beta Adrenergic Receptors having the amino acid residue in position 113 substituted by certain other amino acids have been synthesized. These modified receptors interact with novel ligands that do not react with the natural Asp 113 containing receptors. Transgenic animals containing this modified receptor will respond to novel ligands which will not interact with the normal receptor. RELATED APPLICATION The present application is a continuation-in-part of our copending U.S. Patent Application Serial No. 223,182, filed 22 July, 1988.
摘要:
A method of identifying individual zebrafish ( Danio rerio ), containing the steps of: observing a striped pattern for each of an anal fin and a caudal fin of each individual of two or more zebrafish in side view; determining characteristics of each individual from the observed striped pattern; and identifying each individual on the basis of the characteristics obtained.
