In humans (as in all other mammals, except for monotremes), implantation is the very early stage of pregnancy at which the conceptus adheres to the wall of the uterus. At this stage of prenatal development, the conceptus is a blastocyst. It is by this adhesion that the foetus receives oxygen and nutrients from the mother to be able to grow.
In humans, implantation of a fertilizedovum is most likely to occur about 9 days after ovulation, ranging between 6 and 12 days.
Implantation window
The reception-ready phase of the endometrium of the uterus is usually termed the "implantation window" and lasts about 4 days. The implantation window follows around 6 days after the peak in luteinizing hormone levels. With some disparity between sources, it has been stated to occur from 7 days after ovulation until 9 days after ovulation, or days 6-10 postovulation. On average, it occurs during the 20th to the 23rd day after the last menstrual period.
The implantation window is characterized by changes to the endometrium cells, which aid in the absorption of the uterine fluid. These changes are collectively known as the plasma membrane transformation and bring the blastocyst nearer to the endometrium and immobilize it. During this stage the blastocyst can still be eliminated by being flushed out of the uterus. Scientists have hypothesized that the hormones cause a swelling that fills the flattened out uterine cavity just prior to this stage, which may also help press the blastocyst against the endometrium. The implantation window may also be initiated by other preparations in the endometrium of the uterus, both structurally and in the composition of its secretions.
In humans, an embryo is generally considered to be between the first and the eighth week of development after fertilization, and from then it is instead called a fetus. While most organ systems develop from the third week to the eighth, embryonic life begins at conception.
The development of the embryo is called embryogenesis. In organisms that reproduce sexually, once a sperm fertilizes an egg cell, the result is a cell called the zygote, which possesses half the DNA of each of its two parents. In plants, animals, and some protists, the zygote will begin to divide by mitosis to produce a multicellular organism. The result of this process is an embryo.
Etymology
First attested in English in the mid-14c., the word embryon derives from Medieval Latinembryo, itself from Greekἔμβρυον (embruon), lit. "young one", which is the neuter of ἔμβρυος (embruos), lit. "growing in", from ἐν (en), "in" and βρύω (bruō), "swell, be full"; the proper Latinized form of the Greek term would be embryum.
Pink Floyd bootleg recordings are the collections of audio and video recordings of musical performances by the British rock band Pink Floyd, which were never officially released by the band. The recordings consist of both live performances and outtakes from studio sessions unavailable in official releases. In some cases, certain bootleg recordings may be highly prized among collectors, as at least 40 songs composed by Pink Floyd have never been officially released.
During the 1970s, bands such as Pink Floyd created a lucrative market for the mass production of unofficial recordings with large followings of fans willing to purchase them. In addition, the huge crowds that turned up to these concerts made the effective policing of the audience for the presence of recording equipment virtually impossible. Vast numbers of recordings were issued for profit by bootleg labels.
Some Pink Floyd bootlegs exist in several variations with differing sound quality and length because sometimes listeners have recorded different versions of the same performance at the same time. Pink Floyd was a group that protected its sonic performance, making recording with amateur recording devices difficult. In their career, Pink Floyd played over 1,300 concerts, of which more than 350 were released as bootlegged recordings (sometimes in various versions). Few concerts have ever been broadcast (or repeated once they were broadcast on television), especially during 'the golden age' of the group from 1966 to 1981.
Dr. Paul Holliston (Hudson) is a geneticist who has been living alone in his rambling clinic, which he operates out of his home, after losing his wife in a car crash. This leads to his feeling constant pangs of guilt from his sister-in-law Martha Douglas (Diane Ladd), who has become his assistant.
One night, Holliston runs over a pregnant doberman dog. The dog is fatally injured, but Holliston manages to save one of her unborn puppies by gestating it in an artificial uterus. Because the device still requires nutrients to be supplied by the mother, he must drastically shorten the gestation period: to this end, he uses an experimental growth hormone made from human placental lactogen, which speeds up the embryo's growth.
"Embryo" (sometimes called "The Embryo") is a song by Pink Floyd. It was a concert staple in 1970–71, but a full band version was never released on a Pink Floyd studio album. A studio version did appear in 1970 on the rare multi-artist album Picnic – A Breath of Fresh Air. Its next appearance was in 1983 on Pink Floyd's own compilation called Works. It then appeared in 2007 on A Breath of Fresh Air – A Harvest Records Anthology 1969–1974 (one of only 3 tracks from the original sampler album to be included in the similarly-titled anthology).
History
The studio version of the song, recorded in 1968, was a quiet, almost acoustic piece sung by David Gilmour with a duration of under five minutes. The song ends with an organ solo and high-pitched vocal gibberish (with bassist Roger Waters having sped his voice up, much like he did on "Several Species of Small Furry Animals Gathered Together in a Cave and Grooving with a Pict"). This studio take has not appeared on any Pink Floyd album except Works, an American compilation. A short version similar to the studio cut was recorded "live" for a 2 December 1968 BBC session.
