Water

Water (chemical formula: H₂O) is a transparent fluid which forms the world's streams, lakes, oceans and rain, and is the major constituent of the fluids of organisms. As a chemical compound, a water molecule contains one oxygen and two hydrogen atoms that are connected by covalent bonds. Water is a liquid at standard ambient temperature and pressure, but it often co-exists on Earth with its solid state, ice; and gaseous state, steam (water vapor). It also exists as snow, fog, dew and cloud.

Water covers 71% of the Earth's surface. It is vital for all known forms of life. On Earth, 96.5% of the planet's crust water is found in seas and oceans, 1.7% in groundwater, 1.7% in glaciers and the ice caps of Antarctica and Greenland, a small fraction in other large water bodies, and 0.001% in the air as vapor, clouds (formed of ice and liquid water suspended in air), and precipitation. Only 2.5% of this water is freshwater, and 98.8% of that water is in ice (excepting ice in clouds) and groundwater. Less than 0.3% of all freshwater is in rivers, lakes, and the atmosphere, and an even smaller amount of the Earth's freshwater (0.003%) is contained within biological bodies and manufactured products. A greater quantity of water is found in the earth's interior.

Water (Elitsa & Stoyan song)

"Water" (Bulgarian script: Вода) was the Bulgarian entry in the Eurovision Song Contest 2007, performed in Bulgarian by Elitsa Todorova & Stoyan Yankoulov. This was the first occasion on which the Bulgarian language was used on the Eurovision stage, previous Bulgarian entries being performed in English. Originally titled "Voda", the song had its title translated to English for the Contest.

The song is an up-tempo number with techno influences, as well as a jaw harp and traditional percussion. Todorova sings folk-inspired lyrics dealing with a young girl meeting a young boy riding a horse.

The performance in the semi-final featured the duo wearing what looked like armour, while they were wearing more mainstream clothes in the final. The performances were also notable for the high-energy percussion performances of both musicians.

As Bulgaria had not finished the previous Contest in the top ten, the song was performed in the semi-final. Here, it was performed first (preceding Israel's Teapacks with "Push The Button"). At the close of voting, it had received 146 points, placing 6th in a field of 28 and qualifying Bulgaria for its first final.

Water (2005 film)

Water (Hindi: वाटर), is a 2005 Indo-Canadian film written and directed by Deepa Mehta, with screenplay by Anurag Kashyap. It is set in 1938 and explores the lives of widows at an ashram in Varanasi, India. The film is also the third and final instalment of Mehta's Elements trilogy. It was preceded by Fire (1996) and Earth (1998). Author Bapsi Sidhwa wrote the 2006 novel based upon the film, Water: A Novel, published by Milkweed Press. Sidhwa's earlier novel, Cracking India was the basis for Earth, the second film in the trilogy. Water is a dark introspect into the tales of rural Indian widows in the 1940s and covers controversial subjects such as misogyny and ostracism. The film premiered at the 2005 Toronto International Film Festival, where it was honoured with the Opening Night Gala, and was released across Canada in November of that year. It was first released in India on 9 March 2007.

The film stars Seema Biswas, Lisa Ray, John Abraham, and Sarala Kariyawasam in pivotal roles and Kulbhushan Kharbanda, Waheeda Rehman, Raghuvir Yadav, and Vinay Pathak in supporting roles. Featured songs for the film were composed by A. R. Rahman, with lyrics by Sukhwinder Singh and Raqeeb Alam while the background score was composed by Mychael Danna. Cinematography is by Giles Nuttgens, who has worked with Deepa Mehta on several of her films.

Uppercase

HINT2

Histidine triad nucleotide binding protein 2 (HINT2) is a mitochondrial protein that in humans is encoded by the HINT2 gene on chromosome 9. This protein is an AMP-lysine hydrolase and phosphoamidase and may contribute to tumor suppression.

Structure

As a member of the histidine triad nucleotide-binding (Hint) protein family, which is a subfamily of the histidine triad (HIT) family, HINT2 contains a conserved histidine and HIT sequence motif (His-X-His-X-His-X-X), and the latter two histidines contribute to a catalytic triad. The 163-amino acid protein encoded by this gene forms a 17-kDa homodimer. Compared to other members of the Hint family, HINT2 has a 61% sequence homology to HINT1 and 28% sequence homology to HINT3. When compared with HINT1, the 35–amino acid extension at the HINT2 N-terminal corresponds to a predicted mitochondria import signal.

Function

HINT1

Histidine triad nucleotide-binding protein 1 is a protein that in humans is encoded by the HINT1 gene. It is a haploinsufficient tumor suppressor gene that inhibits the Wnt/β-catenin pathway in colon cancer cells and Microphthalmia-associated transcription factor (MITF) activity in human mast cells. In the LysRS-Ap4A-MITF signaling pathway, HINT1 inhibits the MITF transcriptional activity by direct association. Upon pathway activation, HINT1 is released from MITF by diadenosine tetraphosphate (Ap4A), produced by LysRS.
