CANADA-WHALE HUNT July 22/98 AP PANGNIRTUNG, Northwest Territories -- Inuit hunters in canoes have killed a bowhead whale in the Canadian Arctic, sparking celebrations in their hometown but dismaying conservationists. It was the first hunt of this endangered species in the small Baffin Island community of Pangnirtung in 50 years. The Inuit, which the story says were formerly know as Eskimos, have killed few of the whales in the last five decades because of tight restrictions by the federal government. During land-claims negotiations leading up to the creation of Nunavut, the Inuit obtained the right to resume bowhead hunting, subject to federal approval. News of the successful hunt of a 43-foot whale spread quickly through the region. The whale was butchered Tuesday at the hunters' base camp, with meat and portions of its blubbery outer layer to be shipped to communities throughout Nunavut. The hunt was criticized by animal-rights activists and marine biologists because the bowhead whale is on both Canadian and international lists of endangered species. NEW SCIENTIFIC JOURNAL: CLONING: SCIENCE AND POLICY Co-Editors-in-Chief are Ian Wilmut, Ph.D., and Lee Silver, Ph.D. July 22/98 PRNewswire LARCHMONT, N.Y. -- Cloning: Science and Policy, a new peer-reviewed journal co-edited by Ian Wilmut, Ph.D., and Lee Silver, Ph.D., has been announced by Mary Ann Liebert, Inc., publishers (www.liebertpub.com). The first issue will be published in December. "The Journal will cover all aspects of cloning research and applications," said Ian Wilmut, Ph.D. (Roslin Institute), who cloned Dolly, the sheep. "It will include papers on original investigations into cellular and molecular biology of de-differentiating embryonic stem cells and methods of genetic modifications of animals including germ line gene therapy in humans." "The new results reported by Ryuzo Yanagimachi, Ph.D., and other researchers at the University of Hawaii demonstrate that cloning is no longer just a single scientific result but a burgeoning new technology," said Lee Silver, Ph.D., (Princeton University). "In light of these new results, the establishment of this Journal is more important than ever we will publish both the science and cover the many complex policy and ethical issues that are arising already and will grow as new advances in cloning take place." In a talk given at a scientific meeting last month, Dr. Yanagimachi spoke of the difficulty of getting this paper published; "A journal focusing on cloning will be an important contribution both to the literature and to the field itself," continued Dr. Silver. The Senior Editor of the new journal is Tanja Domenko, D.V.M., Ph.D. (Oregon Regional Primate Research Center). "It is essential to cover the further advancement of nuclear transfer technology and to consolidate basic science with possible applications not just in animal science but also in human medicine," she said today.

July 23/98 Nature VOL.394, No.6691 (pp369-374, N&V) Dolly the cloned sheep is no longer alone. On p369, Ryuzo Yanagimachi of the University of Hawaii, Honolulu in the United States and an international team from the US, Japan, Italy and the United Kingdom report the birth of no fewer than 22 healthy and fertile female mice which have been cloned from nuclei of adult ovarian cumulus cells using a similar technique to that used to produce Dolly. In particular Yamanigachi and colleagues used donor cell nuclei that were in the 'quiescent' G0 stage of the cell division cycle, which seems to have been one of the crucial factors contributing to the success of Dolly. The cloned mice derived from nuclei from cumulus cells, ovarian cells that surround the egg and are shed with it on ovulation, and the first-born of these mice has been named Cumulina. They also tried nuclei from nerve cells and Sertoli cells from the testis, which are also permanently in the G0 stage. But only the cumulus cell nuclei were successful. The previous repeated failures to clone mice by nuclear transplantation had led some to think that the task was simply a biological impossibility. But Yanagimachi's mice seem perfectly normal and have produced offspring of their own after mating. The success rate is still low, however, ranging from 1 in 40 to 1 in 80 survivors for every embryo implanted in different experiments. Successful cloning of mice opens up a better prospect of determining the technical and biological factors that contribute to successful cloning. Developmental biologists will also be able to address the crucial question of how the donor nucleus from a specialized cell becomes reprogrammed by the egg cytoplasm to enable it once again to give rise to all the different cell types in the animal body. Davor Solter at the Max-Planck Institute fur Immunobiologie, Freiburg, Germany, discusses the work along with the latest news on Dolly, in an accompanying News and Views article. CLONING: DOLLY'S DNA PROFILE July 23/98 Nature VOL.394, No.6691 (pp329-330, p330) Dolly the sheep hit the headlines last year as the first animal to be cloned from an adult cell. She was produced by transferring the nuclear material from a mammary cell taken from an adult ewe into an enucleated egg cell. But since the initial reports there have been concerns about Dolly's authenticity. The donor ewe was pregnant at the time the mammary tissue was taken, so, according to some, it is possible that Dolly could have been the product of a fetal cell after all. The first attempts to produce a DNA profile of Dolly suggested that she was indeed an adult clone, but the tests were not detailed enough to remove all doubt. Two reports in this week's scientific correspondence pages, one by Ian Wilmut of the Roslin Institute in Midlothian, UK, and colleagues, who originally produced Dolly (p329), and the other by Esther Signer of the University of Leicester, UK, and colleagues (p330), now provide independent DNA profiles that confirm Dolly was indeed a clone of the 6-year-old donor ewe. Davor Solter at the Max-Planck Institute fr Immunobiologie, Freiburg, Germany, discusses the work along with the work by Yanagimachi and colleagues, in an accompanying News and Views article. NEWS OF CLONED MICE REPRESENTS KEY STEP IN REALISING COMMERCIAL POTENTIAL OF NUCLEAR TRANSFER TECHNOLOGY July 21/98 (from a press release) LONDON -- Roslin Institute today welcomed the publication in today's Nature of news of the cloning of the first mice from adult cells. The publication, by Dr Yanagimachi from the University of Hawaii and colleagues, describes the production of mice by nuclear transfer from cells from the ovaries of adult mice. Dr Ian Wilmut of the Roslin Institute said, "These are exciting results. They suggest that it will be possible to produce adult clones from a range of different cell types and species. Dr Harry Griffin, Assistant Director of Roslin Institute added, "The results will further encourage the commercial development of cloning technology. Roslin Institute has already concluded licenses to Roslin Bio-Med and PPL Therapeutics for the use of its nuclear transfer technology for biomedical applications. The evidence published today from Dr Yanagimachi and his colleagues will provide further encouragement for applications in farm animal production and in human cell therapy, where the ability to clone from adult cells is particularly important." Dr Wilmut went on to say, "Research in mice is much less expensive than in large animals such as sheep and cattle and the work published today will encourage many laboratoriesincluding our ownto use mice in studies to understand the basic mechanisms involved in the 'reprogramming' of adult cells. Studies on mice will also facilitate the use of nuclear transfer for studying mechanisms involved in ageing and in cancer." ROSLIN INSTITUTE: DOLLY THE SHEEP'S PROVENANCE UPHELD; GENETIC FINGERPRINTING PROVES HER ORIGINS July 21/98 >From a press release LONDON -- The following was released today by the Roslin Institute: Independent tests have conclusively proved Dolly the sheep is derived from the nucleus of a cell from the mammary gland of an adult donor. Correspondence published today in the leading scientific journal Nature details independent work carried out by the Department of Genetics at the University of Leicester which verifies Dolly's origins and confirms the work published by the Roslin Institute and PPL Therapeutics in Nature (27.2.97)1. The same issue of Nature also contains details of further DNA microsatellite analysis carried out by specialist genotyping company, Rosgen on behalf of Dolly's creators Roslin Institute and PPL Therapeutics. This second study provides additional confirmation that Dolly was derived from an adult cell. Professor Sir Alec Jeffreys, well known inventor of the DNA fingerprinting technique and his team at Leicester carried out the fingerprinting procedures. Mammary tissue from the original 6-year old donor ewe, cells derived from the tissue and a blood sample from Dolly were all compared. The DNA fingerprints of mammary tissue, cells and Dolly were identical in band number, position and relative intensity. Tissue and cells from the 6-year old ewe had been stored frozen at the Hannah Research Institute ever since their removal and the correspondence also includes details from Dr Colin Wilde and his colleagues at the Hannah that confirm that both tissue and cells used to make Dolly were from the mammary gland of a pregnant ewe. The independent tests were carried out after scientists had suggested that Dolly could have been mistakenly derived from contaminating embryo cells or from a foetal cell present in the bloodstream of the pregnant ewe rather than from an adult cell. The correspondence describing Rosgen's analysis reports that the alleles present in Dolly's DNA were identical to those in the original mammary tissue and also concludes that Dolly was derived from an adult mammary cell of a Finn Dorset ewe. Professor Ian Wilmut of the Roslin Institute said, "Whilst we have always been certain that Dolly was derived from a mammary gland cell from an adult ewe, we are very pleased her origin has now been validated by a wholly independent and highly eminent source." Dr Alan Colman, research director of PPL Therapeutics added, "We hope that this authentication of the Dolly work will now put an end to the doubts expressed by some people over the last few months. Dolly may be a rare event, but she is certainly not an 'anecdote'. Since Dolly, the Roslin Institute and PPL have continued nuclear transfer work using foetal cells and we have successfully demonstrated its commercial benefits with the birth of Polly and other transgenic lambs, and a bull calf, Mr Jefferson. These additional cloned animals show that the technology is now well-proven and established." UK'S PPL THERAPEUTIC IN NEW CLONING DEAL July 22/98 Reuters LONDON -- British biotechnology company PPL Therapeutics Plc was cited as saying today that it has reached an agreement with ProBio America Inc to use its proprietary cloning technology for research into cloning pigs and other animals, adding that it will be part of an international consortium which will be licensed by ProBio to use the Honolulu Cloning Technique for research into animal cloning. PPL's managing director Ron James was qutoed as saying, "If this collaborative research to adapt the mouse to cloning techniques to pigs is successful, we expect it to lead to commercial right in the xenograft (transplant from one species to another) and, possibly other areas." The Honolulu Cloning Technique was developed by Dr Ryuzo Yanagimachi of the University of Hawaii and an international team of scientists from the United States, Japan, Italy and the United Kingdom. BOVINE TB MAY HAVE SPREAD SOUTH IN MICHIGAN July 22/98 UPI JACKSON, Mich. -- State officials were cited as saying today that tests on a Jackson County farm found one cow is a "suspect" for bovine tuberculosis, a lung disease among white-tailed deer that officials are trying to keep from infecting livestock and ruining the state's cattle industry. So far this year one cow in northern Michigan has been confirmed as infected. GENETIC DIVERSITY NEEDS PROTECTION July 23/98 Western Producer Garry Fairbairn Two years ago, according to this editorial, a network of some 600 scientists around the world conducted an ambitious survey of animal life. They looked at 9,615 bird species, 4,355 mammal species, 1,277 reptile species, 497 amphibian species, 2,158 fish species. The results, as reviewed and analyzed in a recent Worldwatch Institute study, found that almost one in five of the surveyed species are in danger of extinction. Researcher John Tuxill, author of the study, was quoted as saying, "We are in the midst of a mass extinction, an event not seen since the disappearance of the dinosaurs 65 million years ago." He adds that habitat destruction, through actions like forest-clearing and roadbuilding, is the primary threat to most of the endangered land species. Overfishing threatens not only the target fish, but other marine life that gets swept up in the nets. Pollution, including agricultural runoff, affects both land and water creatures. Demand for animal parts for aphrodisiacs or natural medicines has led to excessive hunting of tigers and other animals, while the continuing quest for ivory still threatens elephants. The story adds that agriculture is a part of the problem, but it can also contribute to solutions. Tuxill cites one British study that found only seven skylarks after harvest in a field that had been conventionally seeded. Another field seeded with no-till equipment had 157 skylarks, and more than 200 other birds. The editorial concludes that the world's farmers could play important roles, but society needs to support them in doing so. Fair compensation for crop damage, or for land left idle for the benefit of wildlife, should not be a problem for a global society committed to maintaining biodiversity. USING DNA TO DISABLE DISEASES: LOEB INSTITUTE RESEARCHERS ARE DEVELOPING PROTECTION AGAINST DISEASES FOR FARM-BRED FISH July 22/98 The Ottawa Citizen H3 Pauline Tam Joel Heppell, part of a research team at Ottawa's Loeb Research Institute that is, according to this story, developing the world's first fish vaccine made from DNA, was quoted as saying that ``Right now, most of the fish raised on fish farms die from the diseases for which there are no vaccines. Fish farmers can lose a lot of money from high fish mortality rates.'' The technology has found its way to Cobequid Life Sciences Inc., a Richmond Hill-based company focusing on the development of DNA vaccines, which is financing the multi-million dollar effort to bring DNA vaccines for fish to market. Recently, Cobequid received $350,000 from the National Research Council's Industrial Research Assistance Program to help fund the costs of commercializing the fish vaccine. The company, which has a division that specializes in vaccines for farm-raised fish, estimates the global market for its products to be more than $100 million U.S. per year. Cobequid believes DNA vaccines can control several types of viral diseases that conventional, protein-based vaccines on the market today cannot. AT UMDNJ - ROBERT WOOD JOHNSON MEDICAL SCHOOL, LYME DISEASE VACCINE STUDY PROVES SAFE AND 92 PERCENT EFFECTIVE IN ADULTS July 22/98 (from a press release) NEW BRUNSWICK, N.J. -- A new vaccine for Lyme disease has proven 92 percent effective in protecting adults against Lyme disease, reports a researcher at the University of Medicine and Dentistry of New Jersey (UMDNJ) who headed the nationwide study. The results of the three-year, multi-center study are published in the July 23 issue of The New England Journal of Medicine. The report was authored by Dr. Leonard H. Sigal, principal investigator of the study and director of the Lyme Disease Center at the UMDNJ-Robert Wood Johnson Medical School in New Brunswick. The vaccine, called ImuLyme, was developed and is manufactured by Pasteur Merieux Connaught of Swiftwater, Pa. The company is awaiting approval by the U.S. Food and Drug Administration to market the vaccine, which may be available later this year or in early 1999. "The results of this study indicate that this vaccine is an effective source of protection against Lyme disease," said Dr. Sigal, an associate professor of medicine. "Especially in high-risk areas, the vaccine will take its place along with personal precautions as a winning strategy in the prevention of the disease." ImuLyme is a pure protein that is genetically engineered from the bacterial organism that causes Lyme disease. It stimulates the body's immune responses against the Outer Surface Protein found in the bacteria that causes the tick-borne illness. "The vaccine cannot trigger Lyme disease," said Dr. Sigal. "It merely provides protection against the bacteria responsible for the disease. The study included 10,306 people over the age of 17 that began in 1994, with neither physicians nor participants knowing which participants were receiving the vaccine and which were given a placebo, an inactive, harmless substance. The vaccine was tested in New Jersey, New York, Connecticut, Massachusetts, and Wisconsin, where Lyme disease is most common. ImuLyme was administered in two injectives, one month apart. A third dose was given, one year later to ensure the vaccine's effectiveness. Until they received the third dose, the vaccine was only 67 percent effective in preventing Lyme disease. Many of those vaccinated experienced redness, swelling and soreness at the site of the injection, side effect similar to any other intramuscular vaccine, said Dr. Sigal. The side effects dissipated within 72 hours following the injection. In those participants who received the three doses, the vaccine was 100 percent effective in all women and all men under age 60, but only 67 percent effective in men 60 years of age or older. "We do not know why the vaccine was not as thoroughly effective in older men," said Dr. Sigal. "This is an area we are currently studying." Lyme disease is the most common tick-borne infection in the United States. It is caused by a spirochete, a spiral-shaped bacterium called Borrelia Burgdorferi, and is transmitted by the bite of an infected deer tick. Some 98,000 cases of Lyme disease have been reported to the Centers for Disease Control and Prevention since 1992, including about 13,000 last year. The typical features of Lyme disease are a distinctive rash (erythema migrants), arthritis and viral-like symptoms. If left untreated, it can lead to heart, nervous system and joint problems. SASKATCHEWAN ELK DISEASE APPEARS TO BE WANING July 23/98 Western Producer Ed White According to this story, Saskatchewan's farmed elk are free to move again but mystery still surrounds the animal that caused the elk industry lockdown when it died of chronic wasting disease. George Luterbach, the Canadian Food Inspection Agency veterinarian who oversaw the investigation, was quoted as saying, "It would have been nice to show a direct link back." said. Saskatchewan Elk Breeders' Association president Barry Haubrich was quoted as saying, "She's like normal now." Luterbach was cited as saying the most likely source of infection was the animal's mother, whom had been imported from a part of South Dakota where another sick elk had come from. There is some evidence chronic wasting disease can be spread within a herd, but Luterbach added that officials feel confident this animal has not spread the disease. The quarantine on the four farms that contained the infected animal and its relatives has been lifted, but Luterbach said they will be surveyed every six months to see if any animals show signs of disease. RESEARCHERS SEEK HELP July 23/98 Western Producer The Western Beef Development Centre is looking for cow-calf producers to participate in a pasture to plate research program. The centre, based in Saskatoon, wants to work with about 30 cow-calf producers across Western Canada to monitor information from birth to slaughter over a three-year period. Researchers at the centre plan to use the information to check health records, breeding programs, performance and available carcass data. Sonja Lemm, at the centre, said the information can be used to develop breeding programs that focuses on carcass quality and potentially increase profitability of herds. Information will be returned to the producers committed to keeping extensive records on individual animals. The bookkeeping includes records on calves, cows, bulls, weaning data, feeding and packer records. For more information contact Lemm at the Western Beef Development Centre at 306-966-2627. SASKATCHEWAN SIGNS ON TO BEEF LEVY FOR RESEARCH July 23/98 Western Producer D'Arce McMillan A national beef check-off program to fund market development and research is, according to this story, one step closer to reality now that Saskatchewan has signed on. Beginning Aug. 1, a $1 per head deduction will be collected at points of sale by auction markets, dealers and packing plants and by inspectors when animals are exported. This is in addition to the $1 provincial checkoff. Neil Jahnke, chair of the Cattle Marketing Deductions Committee, was cited as saying the money is vital to keep Canada's beef industry competitive in the world market, adding, "When you think Australia is collecting $6 or $7 a head and other countries too. Governments don't have any money any more. So if the industry is going to survive and thrive, we are sure going to have to do some work on the research and promotion side. ... Ontario, Alberta and B.C. have all agreed and Saskatchewan has now agreed so we've got the big end of it." Jim Caldwell, Canadian Cattlemen's Association director of government affairs was cited as saying that negotiations continue with Quebec and a deal looks possible, and that Manitoba needs to change its check-off legislation because it now provides for a voluntary program that allows producers to apply for refunds of the checkoff. And that would cause problems with the CCA's plan to apply the checkoff to imported cattle. The story adds that the program is expected to raise close to $7 million a year nationally, of which about 19 percent will come from Saskatchewan, and that the money will go into a stand-alone corporation managed by a producer committee made up of representatives from the provinces. It will be used to fund domestic beef promotion, export market development and production research. ANIMAL HEALTH: CAUSES OF LEAD POISONING July 23/98 Western Producer Jeff Grognet Every year, according to columnist Grognet, hundreds of cattle die from lead toxicity, and on the Prairies, it is the most common cause of poisoning. In an outbreak, just one calf may be affected or many cows may succumb at the same time. Calves are at greater risk because they are more inquisitive than older animals. Most cases of lead poisoning occur, writes Grognet, because cattle eat discarded material containing lead such as batteries, crankcase oil, grease and used oil filters. A single battery can kill as many as 20 calves. The incidence of lead poisoning has dropped since lead-free paints and gasoline became available. But there are still many sources. Discarded building materials, plumbing supplies, linoleum, oil field waste and remnants of crop sprays all pose a risk. Grognet goes on to advise that if you find a source of lead in the pasture it reinforces the tentative diagnosis. A blood test will confirm lead poisoning. Post mortems can determine if cattle have died from lead toxicity. YOGURT CONTAINER REDESIGNED, BUT ANIMAL ADVOCATES TURN UP THEIR NOSES July 22/98 The Los Angeles Times SUSAN ABRAM First there was dolphin-safe. Now, courtesy of General Mills, we have skunk-safe. It may not carry the same emotional cachet of the dolphins imperiled by tuna nets, but foraging skunks who poke their noses into discarded Yoplait yogurt containers have been dying at a small but noticeable rate for years, animal rights activists say. In an effort to prevent more deaths, which activists estimate to be about 100 nationwide each year, the maker of the No. 2 yogurt brand has modified the tapered Yoplait container to make it animal-safewell, at least animal-safer, and added a warning label to the bottom: "Protect wildlife; crush before disposal." Jack Sheehan, a spokesman for Minneapolis-based General Mills was quoted as saying, "The redesign is somewhat friendlier to small animals," but it is up to consumers to crush the containers before throwing them away. "The [design] changes were already in progress," even before General Mills was contacted by the Animal Protection Institute, a Sacramento-based group concerned about the skunks' predicament, he said. Still, Sheehan said the company wanted consumers to know it was concerned. " But the animal rights activists believe the changes stink. The bushy-tailed, black-and-white creatures are still at risk because the modification to the yogurt containers is too slight, said Camilla Fox, spokeswoman for the Animal Protection Institute. The container's rim curves inward and traps the animal when it sticks its nose and head inside. (General Mills said it curved back the top lip a few millimeters.) PIC RESTRUCTURES BOARD TO FOCUS ON AGRICULTURAL BIOTECHNOLOGY FORMER PIONEER HI BRED INTERNATIONAL, INC., CHAIRMAN JOINS BOARD July 22/98 (from a press release) NEW YORK -- PIC International Group PLC (London: PII), the world's leading provider of genetically improved pigs used for breeding, has announced changes to its Board of Directors in order to reflect the company's focus on agricultural biotechnology. In connection with this restructuring, Phillip J. David was named Chief Executive Officer, effective September 30. PIC International emerged from a recent restructuring in which the U.K.-based Dalgety disposed of four food and agricultural businesses for 1.25 billion pounds and returned 675 million pounds to shareholders. Dalgety recently changed its name to PIC International Group. Tom Urban, former Chairman of Pioneer Hi Bred International, Inc., has been appointed to the Board of Directors, effective October 1. "In his nearly 40 years of experience with Pioneer, Tom led the company to become one of the leading agricultural research and seed genetic companies in the world. His expertise and knowledge will be of tremendous value as we continue to expand our genetic improvement business," said Mr. David. Gregg BeVier, President of PIC Americas, will join the PIC International Group Board on October 1. Mr. BeVier joined PIC Americas in 1983 and has extensive experience in the pig improvement sector of the agricultural biotechnology industry. Brian Baldock, will become non-executive chairman of the Board. Mr. Baldock has been a non-executive director of PIC for six years and is also a director of Marks & Spencer PLC and Cornhill Insurance PLC. Concurrent with these appointments, PIC announced that it will relocate its headquarters and research center to Berkeley, California, from the U.K. in order to attract leading biotechnology scientists. PIC intends to seek a U.S. stock market listing, in addition to the current London listing. Andrew Allner, PIC group finance director, will relocate to California later this year. Prior to joining Dalgety as group finance director in 1998, Mr. Allner was finance director of Nycomed-Amersham plc, a biotechnology, imaging and pharmaceutical group. "PIC is particularly well positioned as the industry leader in the field of genetically improved pigs and we will continue our geographic expansion into emerging growth markets, particularly in the Far East," said Mr. David. "The relocation of the company to the San Francisco area provides us with access to the best research talent in the field, as well as an enhanced ability to develop attractive long-term markets."
