Juno is a large asteroid in the asteroid belt. Juno was the third asteroid discovered, in 1804, by German astronomer Karl Harding. It is one of the twenty largest asteroids and one of the two largest stony (S-type) asteroids, along with 15 Eunomia. It is estimated to contain 1% of the total mass of the asteroid belt.
Dione, also designated Saturn IV, is the fourth-largest moon of Saturn. With a mean diameter of 1,123 km and a density of about 1.48 g/cm3, Dione is composed of an icy mantle and crust overlying a silicate rocky core, with rock and water ice roughly equal in mass. Its trailing hemisphere is marked by large cliffs and scarps called chasmata; the trailing hemisphere is also significantly darker compared to the leading hemisphere.
Carotenoids are yellow, orange, and red organic pigments that are produced by plants and algae, as well as several bacteria, archaea, and fungi. Carotenoids give the characteristic color to pumpkins, carrots, parsnips, corn, tomatoes, canaries, flamingos, salmon, lobster, shrimp, and daffodils. Over 1,100 identified carotenoids can be further categorized into two classes – xanthophylls and carotenes.
Androstenedione, or 4-androstenedione, also known as androst-4-ene-3,17-dione, is an endogenous weak androgen steroid hormone and intermediate in the biosynthesis of estrone and of testosterone from dehydroepiandrosterone (DHEA). It is closely related to androstenediol (androst-5-ene-3β,17β-diol).
In ancient Greek religion and Greek mythology, Dione is an oracular goddess, a Titaness primarily known from Book V of Homer's Iliad, where she tends to the wounds suffered by her daughter Aphrodite. Dione is presented as either an Oceanid, daughter of Oceanus and Tethys, or the thirteenth Titan, daughter of Gaia and Uranus.
HMS Juno was a Leander-class frigate of the Royal Navy (RN). Like the rest of the class, Juno was named after a figure of mythology. She was built by Thornycroft of Woolston, Hampshire. Juno was launched on 24 November 1965 and commissioned on 18 July 1967.
Juno was an ancient Roman goddess, the protector and special counsellor of the state. She was equated to Hera, queen of the gods in Greek mythology and a goddess of love and marriage. A daughter of Saturn and Ops, she was the sister and wife of Jupiter and the mother of Mars, Vulcan, Bellona, Lucina and Juventas. Like Hera, her sacred animal was the peacock. Her Etruscan counterpart was Uni, and she was said to also watch over the women of Rome. As the patron goddess of Rome and the Roman Empire, Juno was called Regina ("Queen") and was a member of the Capitoline Triad, centered on the Capitoline Hill in Rome, and also including Jupiter, and Minerva, goddess of wisdom.
Polydeuces, also designated Saturn XXXIV, is a small trojan moon of Saturn occupying the trailing L5 Lagrange point of Dione. It was discovered by the Cassini Imaging Science Team in images taken by the Cassini space probe on 21 October 2004. With a mean diameter of about 3 km (1.9 mi), Polydeuces is thought to have a smooth surface coated with fine, icy particles accumulated from the cryovolcanic plumes of Enceladus. In its orbit around Saturn, Polydeuces periodically drifts away from Dione's Lagrange point due to gravitational perturbations by other nearby moons of Saturn. Of the four known trojan moons of Saturn, Polydeuces exhibits the largest displacement from its Lagrange point.
Dione Taylor is a Canadian blues, roots, soul and jazz singer/songwriter, born and raised in Regina, Saskatchewan. Dione calls her music the “Prairie Blues”, which is a mixture of Roots, Blues, Gospel and Americana. She is influenced by vocalists such as Aretha Franklin, Sister Rosetta Tharpe, Son House and Sarah Vaughan. She released her first album, Open Your Eyes, in 2004, and it was nominated for Vocal Jazz Album of the Year at the Juno Awards of 2005.
Atamestane, also known as metandroden, as well as 1-methylandrosta-1,4-diene-3,17-dione, is a steroidal aromatase inhibitor that was studied in the treatment of cancer. It blocks the production of estrogen in the body. The drug is selective, competitive, and irreversible in its inhibition of aromatase.
Epiandrosterone, or isoandrosterone, also known as 3β-androsterone, 3β-hydroxy-5α-androstan-17-one, or 5α-androstan-3β-ol-17-one, is a steroid hormone with weak androgenic activity. It is a metabolite of testosterone and dihydrotestosterone (DHT). It was first isolated in 1931, by Adolf Friedrich Johann Butenandt and Kurt Tscherning. They distilled over 17,000 litres of male urine, from which they got 50 milligrams of crystalline androsterone, which was sufficient to find that the chemical formula was very similar to estrone.
Heliconiini is a tribe of butterflies in the subfamily Heliconiinae, also known as the passion-vine butterflies. This group has roughly 100 species and subspecies distributed primarily in the Neotropics.
Retroprogesterone, also known as 9β,10α-progesterone or as 9β,10α-pregn-4-ene-3,20-dione, is a progestin which was never marketed. It is a stereoisomer of the naturally occurring progestogen progesterone, in which the hydrogen atom at the 9th carbon is in the α-position instead of the β-position and the methyl group at the 10th carbon is in the β-position instead of the α-position. In other words, the atom positions at the two carbons have been reversed relative to progesterone, hence the name retroprogesterone. This reversal results in a "bent" configuration in which the plane of rings A and B is orientated at a 60° angle below the rings C and D. This configuration is ideal for interaction with the progesterone receptor, with retroprogesterone binding with high affinity to this receptor. However, the configuration is not as ideal for binding to other steroid hormone receptors, and as a result, retroprogesterone derivatives have increased selectivity for the progesterone receptor relative to progesterone.
11β-Hydroxyandrostenedione (11β-OHA4), also known as 11β-hydroxyandrost-4-ene-3,17-dione, is an endogenous, naturally occurring steroid and androgen prohormone that is produced primarily, if not exclusively, in the adrenal glands. It is closely related to adrenosterone, 11-ketotestosterone (11-KT), and 11-ketodihydrotestosterone (11-KDHT), which are also produced in the adrenal glands.
19-Nor-5-androstenedione, also known as estr-5-ene-3,17-dione, is a synthetic, orally active anabolic-androgenic steroid (AAS) and a derivative of 19-nortestosterone (nandrolone) that was never introduced for medical use. It is an androgen prohormone of nandrolone and of other 19-norandrostanes.
Elaphe dione, commonly known as Dione's rat snake, the steppe rat snake, or the steppes rat snake, is a species of snake in the family Colubridae. The species is native to Asia and Eastern Europe. There are no subspecies that are recognized as being valid. A large specimen from Putyatin Island measured up to 90 cm (3.0 ft) in length.
7α-Thioprogesterone is a synthetic, steroidal, and potent antimineralocorticoid (putative) and antiandrogen which was developed by G. D. Searle & Co and was described in the late 1970s and early 1980s but was never developed or introduced for medical use. It is a derivative of progesterone (pregn-4-ene-3,20-dione) with a thio (sulfur) substitution at the C7α position, and is related to the spirolactone group of drugs but lacks a γ-lactone ring.
19-Nordehydroepiandrosterone (19-nor-DHEA), or 19-nor-5-dehydroepiandrosterone (19-nor-5-DHEA), is an estrane (19-norandrostane) steroid which was never marketed. It is the combined derivative of the androgen/anabolic steroid nandrolone (19-nortestosterone) and the androgen prohormone dehydroepiandrosterone. Related compounds include 19-nor-5-androstenediol, bolandiol (19-nor-4-androstenediol), and bolandione (nor-4-androstenedione), which are all known orally active prohormones of nandrolone. 19-Nor-DHEA may occur as a metabolite of bolandione and related steroids.
