Text: A blighted ovum or anembryonic gestation is characterized by a normal-appearing gestational sac, but the absence of an embryo. It likely occurs as a result of early embryonic death with continued development of the trophoblast. When small, the sac cannot be distinguished from the early normal pregnancy, as there may be a yolk sac, though a fetal pole is not seen. For diagnosis, the sac must be of sufficient size that the absence of normal embryonic elements is established. The criteria depends on the type of ultrasound exam performed. A pregnancy is anembryonic if a transvaginal ultrasound reveals a sac with a mean gestational sac diameter (MGD) greater than 25 mm and no yolk sac, or an MGD >25 mm with no embryo. Transabdominal imaging without transvaginal scanning may be sufficient for diagnosing early pregnancy failure when an embryo whose crown--rump length is 15 mm or more has no visible cardiac activity.

Text: The cell membrane (also known as the plasma membrane or cytoplasmic membrane, and historically referred to as the plasmalemma) is a biological membrane that separates the interior of all cells from the outside environment (the extracellular space). It consists of a lipid bilayer with embedded proteins. The basic function of the cell membrane is to protect the cell from its surroundings. The cell membrane controls the movement of substances in and out of cells and organelles. In this way, it is selectively permeable to ions and organic molecules. In addition, cell membranes are involved in a variety of cellular processes such as cell adhesion, ion conductivity and cell signalling and serve as the attachment surface for several extracellular structures, including the cell wall, the carbohydrate layer called the glycocalyx, and the intracellular network of protein fibers called the cytoskeleton. In the field of synthetic biology, cell membranes can be artificially reassembled.

Text: Drinking in public is legal in England and Wales -- one may carry a drink from a public house down the street (though it is preferred that the user requests a plastic glass to avoid danger of breakage and because the taking of the glass could be considered an offence of Theft as only the drink has been purchased), and one may purchase alcohol at an off-licence and immediately begin drinking it outside. Separately, one may drink on aeroplanes and on most National Rail train services, either purchasing alcohol on-board or consuming one's own.

Text: The National Gallery of Art is supported through a private-public partnership. The United States federal government provides funds, through annual appropriations, to support the museum's operations and maintenance. All artwork, as well as special programs, are provided through private donations and funds. The museum is not part of the Smithsonian Institution.
