[Beatrice H. Hahn] reported, the findings show 'for the first time a clear picture of the origin of HIV-1 and the seeds of the AIDS pandemic.' Studies estimate that the human AIDS virus jumped species between 50 and 75 years ago. But no one knows who the first infected person was or how that person acquired HIV. Hahn said her team theorizes that HIV was first transmitted locally somewhere in west central Africa. Because the subspecies of chimpanzees, Pan troglodytes troglodytes, in which the simian virus had been found in captivity, lives in the wild in Cameroon, Gabon and Republic of Congo, the first infection could have been in any of those areas

[Beatrice Hahn] reported, her team's findings show 'for the first time a clear picture of the origin of HIV-1 and the seeds of the AIDS pandemic.' HIV-1 is the virus that causes the vast majority of AIDS cases in the world. The first cases of AIDS were detected in the United States in 1981. Hahn said her team theorizes that HIV was first transmitted locally somewhere in west central Africa. The subspecies of chimpanzees, Pan troglodytes troglo-dytes, in which the simian virus had been found in captivity, lives in the wild in Cameroon, Gabon and Republic of Congo; therefore, the first infection could have been in any of those areas. It is not known whether chimpanzees infected with SIVcpz become ill, Hahn said. Two naturally infected chimpanzees in captivity did not become ill. Some infected chimpanzees that were rescued as orphans because their parents were killed for bush meat died in captivity, but others that were not infected also died, she said, and the deaths were attributed to human infection, poor care and inappropriate diet

The genetic and immunologic tests were developed in stages over the past seven years to help trace the evolution of H.I.V. and solve the mysterious origins of AIDS, said Dr. Beatrice H. Hahn, a virologist at the University of Alabama in Birmingham. Dr. Hahn led the international team that conducted the study, which combined genetics and epidemiology. Dr. Hahn reported, her team's findings show ''for the first time a clear picture of the origin of H.I.V.-1 and the seeds of the AIDS pandemic.'' H.I.V.-1 is the virus that causes the vast majority of AIDS cases in the world. The first cases of AIDS were detected in the United States in 1981.

The World Health Organization said it had developed 20 standards for improving reporting on the testing of drugs and devices on people and urged researchers and companies to use them in all human..

Because Hepatitis B is endemic in many Asian countries, growth in the number of Asian immigrants in New York and across the country has made the disease a broad, expensive, emerging health problem. In the 2000 census, there were 800,000 Asians in the city, with roughly half from China. Hepatitis B, like hepatitis C, is generally contracted through the blood, and is not transmitted through casual contact with infected people. Hepatitis A, which is caused by a different virus, can be transmitted through food, but hepatitis B cannot, with very rare exceptions. Early detection and suppression of the virus can interrupt the cycle of mother-to-child transmission. An adult immune system can usually fight off a new hepatitis B infection, though a small number of cases become chronic. But, Dr. [Henry J. Pollack] said, ''If you get it when you're an infant, your chance of getting chronic hepatitis B is greater than 90 percent.''

Senator Hillary Rodham Clinton, Democrat of New York, said that failed to resolve the issue of leadership. ''Under the president's plan,'' Mrs. Clinton said, ''we still don't know who is accountable within our federal government.'' ''In the Northwest, we have 42,000 travelers going and coming from Asia every week,'' Ms. [Mary Selecky] said. ''We don't want to have to deal in an isolated way with a plane carrying potentially infected people.'' ''They gave us a list of work that they expect us to do,'' Ms. Selecky said, ''but they've only given us a little bit of one-time money. We need a sustained effort.''

Since AIDS first made headlines 25 years ago, it killed 25 million people worldwide and infect 40 million more in one of the worst epidemics in history. Altman relates that in 1985 he was greeted with skepticism about AIDS in Africa, even though the disease had begun to take a devastating toll there. Here, he details the outbreak of AIDS and why many people, including doctors, did not recognize an epidemic in the making and take steps to try to contain it

The show stopped. In a test of the crew's agility and ingenuity, [Gary Razon] supervised the eight stewards it took to dislodge the woman and carry her to the infirmary. Razon said he 'was so scared because the ship was bouncing and feared she might be bleeding from the hip fracture.' Razon could not reach the nephews. From other calls, he learned that the passenger's mother also was also demented. Her nurse provided the name of the woman's psychiatrist, who was skiing. Razon could not reach the covering physician and sent the woman to a hospital after the ship docked in Nassau. A colleague who was a ship's doctor whetted Razon's appetite for a chance to see the world while practising medicine. Razon said he has travelled to many areas but has had less time ashore than he had expected. Still, he said, 'Being a ship's doctor is an offer I cannot refuse.'

As a cruise ship physician, Dr. Gary Razon's most harrowing moments are when passengers and crew become injured or seriously ill hundreds of kilometers from shore. Sudden life-threatening emergencies like internal bleeding, heart attacks, strokes and broken bones can leave little, if any, time to divert a ship to the nearest port. The challenge for a ship's doctor is to stabilize a patient until the ship reaches land. Razon could not reach the nephews. From other calls, he learned that the passenger's mother also was also demented. Her nurse provided the name of the woman's psychiatrist, who was skiing. Razon could not reach the covering physician and sent the woman to a hospital after the ship docked in Nassau. He became a ship's doctor after a colleague, who was one, whetted his appetite about the chance to see the world while practicing medicine. Razon said he had traveled to many areas but with less time ashore than he had expected. Still, Razon said, 'Being a ship's doctor is an offer I cannot refuse.'

It takes about two months to grow the new bladder on a scaffold outside the body. After implantation, the engineered bladder enlarges over time in the recipient. The researchers say they expect that the new bladder will last a patient's lifetime, but the longevity will be known only as the children grow older. A major advantage of his technique is that rejection cannot occur because the cells used to create a new bladder are from the patient, not from another individual. So an ultimate aim -- still years off -- is to develop the technique to grow a wide variety of other tissues, possibly even organs, to help relieve the shortage of donor organs available for transplanting, said the research team's leader, Dr. Anthony Atala. He directs the Institute for Regenerative Medicine at Wake Forest University Baptist Medical Center in Winston-Salem, N.C. After the new bladder formed, in about seven to eight weeks, Dr. Atala removed a large portion of the patient's bladder. Then he sewed the newly created tissue to what is known as the neck of the bladder and to the rest of the remaining portion of the patient's natural bladder
