Aging research in vertebrates is hampered by the lack of short-lived models. Annual fishes of the genus Nothobranchius live in East African seasonal ponds. Their life expectancy in the wild is limited by the duration of the wet season and their lifespan in captivity is also short. Nothobranchius are popular aquarium fishes and many different species are kept as captive strains, providing rich material for comparative studies. The present paper aims at reviving the interest in these fishes by reporting that: (1) Nothobranchius can be cultured, and their eggs stored dry at room temperature for months or years, offering inexpensive methods of embryo storage; (2) Nothobranchius show accelerated growth and expression of aging biomarkers at the level of histology and behaviour; (3) the species Nothobranchius furzeri has a maximum lifespan of only 3 months and offers the possibility to perform investigations thus far unthinkable in a vertebrate, such as drug screening with life-long pharmacological treatments and experimental evolution; (4) when the lifespan of different species is compared, a general correlation is found between wet season duration in their natural habitat and longevity in captivity; and (5) vertebrate aging-related genes, such as p66Shc and MTP, can be easily isolated in Nothobranchius by homology cloning. These fishes can become excellent models for aging studies. They can be employed to test the effects of experimental manipulation on aging at a pace comparable with that of Drosophila and to probe the effects of natural selection on the evolution of aging-related genes.

Ex Output:
What can Nothobranchius furzeri be used as a model system for?

In the Atlantic, the West India Company concentrated on wresting from Portugal its grip on the sugar and slave trade, and on opportunistic attacks on the Spanish treasure fleets on their homeward bound voyage. Bahia on the north east coast of Brazil was captured in 1624 but only held for a year before it was recaptured by a joint Spanish-Portuguese expedition. In 1628, Piet Heyn captured the entire Spanish treasure fleet, and made off with a vast fortune in precious metals and goods that enabled the Company two years later to pay its shareholders a cash dividend of 70%, though the Company was to have relatively few other successes against the Spanish. In 1630, the Dutch occupied the Portuguese sugar-settlement of Pernambuco and over the next few years pushed inland, annexing the sugar plantations that surrounded it. In order to supply the plantations with the manpower they required, a successful expedition was launched in 1637 from Brazil to capture the Portuguese slaving post of Elmina, and in 1641 successfully captured the Portuguese settlements in Angola. In 1642, the Dutch captured the Portuguese possession of Axim in Africa. By 1650, the West India Company was firmly in control of both the sugar and slave trades, and had occupied the Caribbean islands of Sint Maarten, Curacao, Aruba and Bonaire in order to guarantee access to the islands' salt-pans.

What were two things the West India Company desired?

On an October morning in 1951, Norman Dale (Gene Hackman) drives through the Indiana countryside. In the afternoon he arrives in the small rural town of Hickory and enters the high school. He notices, on a shelf in the hall, basketball trophies won in previous years. As the bell rings to end the school day, he encounters teacher Myra Fleener (Barbara Hershey). She realizes that Norman must be the new basketball coach and teacher of history and civics. She directs him to the office of principal Cletus Summers (Sheb Wooley), where the two men recall how they met many years ago at Buffalo State Teachers College. They had lost touch until recently, when Cletus tracked down Norman and asked him to come coach at Hickory. When Norman thanks Cletus for the opportunity, Cletus interrupts and says, "Your slate's clean here." They proceed to the gym, where student Jimmy Chitwood (Maris Valainis) is shooting baskets. Cletus introduces Norman, but Jimmy ignores the new coach and keeps shooting.That evening on his farm, Cletus explains to Norman that Jimmy has been strongly affected by the recent death of the previous coach, who was like a father to Jimmy. Now the young man has withdrawn from almost everything and everyone and has decided not to play basketball this season. Cletus adds that Jimmy is the best player he has ever seen. As they finish talking, Norman cryptically mentions that he hopes things will work out for him this time.That night, Norman meets some of the townsmen in the barbershop, who bombard him with questions. He tells them he last coached 12 years ago, in Ithaca, New York, and that he has been in the Navy for the past 10 years. The men voice their opinions on what Norman should do with the team. They all agree that Jimmy must rejoin the Huskers for them to have a winning season. Losing patience with all the questions and unwelcome advice, Norman cuts short the meet-and-greet and leaves.The next morning, before school begins, Myra tells Norman that Jimmy is her neighbor, and she has been looking out for him ever since his father died. She thinks it best that he stay off the team. After school, the Huskers are already practicing in the gym when Norman walks in. George Walker (Chelcie Ross), one of the townspeople Norman met in the barbershop, is leading the practice and assumes that Norman will continue allowing him to assist. When Norman brusquely makes it clear that he doesn't need any help, George storms off. As Norman gathers the seven Huskers and begins to introduce himself, Buddy (Brad Long) rudely whispers to his teammate Whit (Brad Boyle), who is standing next to him. Norman orders Buddy to leave, and Buddy convinces Whit to go with him. Jimmy is watching, unseen, at one of the far exits. Norman begins the practice and puts the Huskers through drills of passing, running in place, and dribbling while weaving between chairs; they never scrimmage. Norman explains, "There's more to the game than shooting. There's fundamentals and defense." He also wants them to be in top physical condition because, if they continue to have only five players, substitutions and rest during games will be impossible. On the second day of practice, several townspeople walk in to observe; they've heard about Norman's unusual drills. Rollin Butcher (Robert Swan), Whit's father, brings in his son and has him apologize for walking out the day before. Rollin then tells the other men to leave, because the coach doesn't want them there.One day, as Cletus and Norman eat pie at the diner downtown, in comes Wilbur "Shooter" Flatch (Dennis Hopper), stumbling a bit and wearing a worn-out coat. Shooter, a former basketball player, describes for Norman how he almost led his team to victory in the 1933 sectional game of the tournament on a last-second shot. When Shooter asks Cletus in a low voice if he can borrow some spare change, Shooter's son, Everett (David Neidorf), who
