The present invention relates to a disposable clothing cover that has an integrated napkin. The cover provides the functionality of a bib and a napkin and prohibits clothes from inadvertently becoming stained. The cover has cloth friendly adhesive lines which are used for removably attaching the cover to clothing of a wearer. A perforated curved portion positioned below the neck of a wearer of the cover is configured to be detached and functions like a napkin while the remaining part of the cover functions as a bib. The cover has a pair of adhesive tabs that can be used for securing a folded bottom edge of the cover enabling the creation of a pocket at the bottom of the cover to catch food items dropped during eating and drinking. The clothing cover can be packaged individually, formed in a roll, or stacked in a dispenser box.
摘要:
The present disclosure provides a method of generating progenitor cells, such as hematopoietic or neural progenitor cells, from fibroblasts, such as dermal fibroblasts, comprising providing fibroblasts that express or are treated with a POU domain containing gene or protein and culturing the cells under conditions that allow production of progenitor cells, without traversing the pluripotent state. Also provided is a method of isolating a subpopulation of fibroblasts with reprogramming potential comprising providing fibroblasts that express an Oct-4-reporter and isolating cells that are positive for the reporter. Further provided is a method of generating reprogrammed fibroblast-derived induced pluripotent stem cells. Also provided are uses and assays of the cells produced by the methods of the disclosure.

摘要:
The present disclosure provides transformed human pluripotent stem cell (t-hPSC). t-hPSCs are not dependent on Oct4 for renewal and survival, however exhibit a sensitivity to reduced levels of the transcription factor Nanog. Also provided are methods of culturing cells for use in a cell-based screening assay comprising placing one or more transformed human pluripotent stem cells into a receptacle and culturing said stem cells in the receptacle to form a monolayer of stem cells without cell overlap. Methods of screening compounds using t-hPSCs are also described.
摘要:
This invention relates to a new and improved process for the preparation of 6,7-dichloro-1,5-dihydroimidazo[2,1-b]-quinazolin-2[3H]-one of formula ##STR1## (anagrelide), a valuable blood platelet antiaggregative compound. According to the process of the invention the compound of formula (I) is prepared by subjecting a new 2-cyanoiminoquinazoline derivative of the general formula ##STR2## wherein R stands for cyano or a group of the formula COOR.sup.1, in the latter R.sup.1 representing lower alkyl optionally carrying a phenyl substituent, to thermal cyclization in an acidic medium.The invention also relates to new 2-cyanoiminoquinazo-lines of the general formula (III) used for the production of anagrelide and to the preparation of the said compounds.The invention provides an advantageous process for the preparation of anagrelide which is devoid of the drawbacks of the hitherto known processes and renders possible the production of the compound of the formula (I) on industrial scale, too.
