Pepper painkiller hot topic among doctors

Bite a hot pepper, and after the burn your tongue goes numb. The hope is that bathing surgically exposed nerves in a high-enough dose will numb them for weeks, so that patients suffer less pain and require fewer narcotic painkillers as they heal. “We wanted to exploit this numbness” is how Dr. Eske Aasvang, a pain specialist in Denmark who is testing the substance, puts it. Chili peppers have been part of folk remedy for centuries, and heat-inducing capsaicin creams are a drugstore staple for aching muscles. But today the spice is hot because of research showing that capsaicin targets key pain-sensing cells in a unique way. California-based Anesiva Inc.’s operating-room experiments aren’t the only attempt to harness that burn for more focused pain relief. WASHINGTON: Doctors are experimenting with a chemical that makes peppers hot as a numbing agent during painful surgeries. Devil’s Revenge. Spontaneous Combustion. Hot sauces have names like that for a reason. Now scientists are testing whether the stuff that makes the sauces so savage can tame the pain of surgery. Doctors are dripping the chemical that gives chili peppers their fire directly into open wounds during knee replacement and a few other highly painful operations. Don’t try this at home: These experiments use an ultra-purified version of capsaicin to avoid infection – and the volunteers are under anesthesia so they don’t scream at the initial burn. Harvard University researchers are mixing capsaicin with another anesthetic in hopes of developing epidurals that wouldn’t confine women to bed during childbirth, or dental injections that don’t numb the whole mouth. And at the National Institutes of Health, scientists hope early next year to begin testing in advanced cancer patients a capsaicin cousin that is 1,000 times more potent, to see if it can zap their intractable pain. Nerve cells that sense a type of long-term throbbing pain bear a receptor, or gate, called TRPV1. Capsaicin binds to that receptor and opens it to enter only those pain fibers – and not other nerves responsible for other kinds of pain or other functions such as movement. These so-called C neurons also sense heat; thus capsaicin’s burn. But when TRPV1 opens, it lets extra calcium inside the cells until the nerves become overloaded and shut down. That’s the numbness. “It just required a new outlook about … stimulation of this receptor” to turn those cellular discoveries into a therapy hunt, says the NIH’s Dr. Michael Iadarola. Enter Anesiva’s specially purified capsaicin, called Adlea. Experiments are under way involving several hundred patients undergoing various surgeries, including knee and hip replacements. Surgeons drip either Adlea or a dummy solution into the cut muscle and tissue and wait five minutes for it to soak in before stitching up the wound. Among early results: In a test of 41 men undergoing open hernia repair, capsaicin recipients reported significantly less pain in the first three days after surgery, Aasvang reported this month at a meeting of the American Society of Anesthesiologists. Ongoing studies are testing larger doses in more patients to see whether the effect is real.160Want local news?Sign up for the Localist and stay informed Something went wrong.

Unesco media literacy workshop

first_imgMedia literacy has been a component ofSouth African schooling for some years.(Image: FreeDigitalPhotos.net)MEDIA CONTACTS • Jaco du ToitUnesco regional office, Windhoek+264 61 291 7221RELATED ARTICLES• Unesco, AU to boost African journalism• Unesco lauds SA literacy project• Social development in SOuth Africa• SA celebrates media freedomJanine ErasmusA three-day regional teacher workshop to be held in early November 2009 in Pretoria, South Africa, aims to boost literacy in new media and information skills. The workshop is a joint project of the United Nations Educational, Scientific and Cultural Organisation (Unesco) and the University of Pretoria.At least 20 teacher trainers from countries in the Southern African region, including South Africa, Swaziland, Lesotho and Namibia, are to attend. Similar regional events will take place in Montego Bay, Jamaica, to cover teacher training institutions in Latin America and the Caribbean; as well as in Colombo, Sri Lanka, for teacher training institutions in the South Asia region.The event centres on Unesco’s draft media and information literacy (MIL) curriculum for teacher education, which is soon to be piloted in teacher training institutions in at least eight developing countries.Trainers at the African event will be brought up to speed with the latest developments in the field of media and information literacy as it pertains to teacher education. They will also have the opportunity to discuss the draft curriculum and give their feedback on it, both as a whole and for specific modules. This feedback is expected to enhance the draft.The development of the MIL programme is steered by an international expert group. Local media education expert Professor Fackson Banda, the SABMiller-Unesco Chair of Media and Democracy at Rhodes University’s journalism school, represents the country in this group. Visiting professor Albert Boekhorst, an information scientist connected to Pretoria University’s Department of Information Science, also works on the project.The group meets regularly to review the curriculum’s progress and make recommendations for its further improvement. The upcoming workshop is an extension of the ongoing validation process.Media expert Professor Birgitte Tufte of the Copenhagen Business School names South Africa as one of the world’s leading countries in media education, along with Australia, Canada, and Great Britain. Other countries slowly following suit include the Netherlands, Italy, Greece, Austria, and Switzerland.South Africa held its first media education conference in 1990 and has seen an increasing demand for media education since the arrival of democracy in 1994.Understanding the mediaThe Alexandria Proclamation says that information literacy and life-long learning are “beacons of the Information Society, illuminating the courses to development, prosperity and freedom”. The proclamation was drawn up at a colloquium on information literacy and life-long learning held in Alexandria, Egypt, in November 2005.Media and communication technologies, says Unesco, are crucial in keeping people informed so that they can competently assess, process and use media, in a variety of forms, in their personal lives and careers.This competency allows citizens to participate usefully in democratic societies. It also allows them to create their own functional media messages.Media and information technologies also stimulate creativity and debate on a range of issues, but their effectiveness is entirely dependent on the audience’s ability to understand, process and use the information while filtering out propaganda and bias.The MIL programme aims to foster literacy in mass media as well as information and communication technologies among the youth of the world, who are today’s most eager media consumers, according to Unesco. These children obtain their news not only through traditional channels but also through new platforms such as social networking sites, where they interact with their peers.However, because of their tender age, these consumers are also most vulnerable to the dangers of misusing or misinterpreting the media.Before media literacy programmes are included in school teaching, a number of obstacles must be overcome, including overworked teachers and already full curricula. South Africa’s own school curriculum has undergone a number of revisions since 1994, when the controversial outcomes-based system was phased in. The 2008 group of matrics was the first to write their final exams under the new system.Teachers themselves need media and information literacy education to be able to understand the role and importance of media, and to be able to equip their pupils with the same skills.Unesco will work towards the inclusion of media literacy in national teacher training curricula, thus creating a ripple effect that will eventually filter down to pupils of secondary education level. The results and effectiveness of eight pilot projects will be shared with government education departments, and will determine the level of integration into national curricula.The integration of libraries into the programme is another crucial step, as libraries offer an environment with valuable resources and services, and play an important role in the life-long learning process.last_img read more

London Olympics: Podobedova wins 4th gold for Kazakhstan in women’s 75kg weightlifting

first_imgSvetlana Podobedova won Olympic gold for Kazakhstan by the narrowest of margins on Friday, edging out Russia’s Natalya Zabolotnaya in the women’s 75kg weightlifting by virtue of lighter body weight. Podobedova and Zabolotnaya both broke the Olympic record with totals of 291 kg, with the Russian setting down a new Olympic best of 131 kg in the snatch and Podobedova setting a new Olympic record of 161 kg in the clean and jerk. Podobedova was born in Russia and represented that country until she was stripped of her 2006 world junior title for doping, after which she switched allegiance to Kazakhstan. “I am grateful I could compete. In 2008 Russia didn’t allow me to go to Beijing but Kazhakstan gave me a chance. I started training for this slowly, and this gold is for Kazhakstan,” she said. “I just wished for it so much. I have been working towards this all my life.” Official results show the total Olympic record awarded to Zabolotnaya, who only joined the Russian team last week after Oksana Slivenko withdrew with injury. Belarusian lifter Iryna Kulesha was a distant third with a total of 269 kg. Podobedova’s victory brings Kazakhstan its fourth gold of the games and third in women’s weightlifting, after Zulfiya Chinshanlo won the 53kg category and Maiya Maneza took victory in the 63kg event.last_img read more
