A new test for hepatitis C in blood units

Posted on 01. May, 2009 by in Education in Science, Experiments & Research, Health & Medicine, News

1112A new test could allow a major breakthrough in the fight against hepatitis C. According to the University of Bonn, this method would be for an equivalent sensitivity, significantly less costly than the usual commercial tests. For the first time, poorer countries would be able to test for hepatitis C in blood units on a large scale and with the best methods available.

The test was developed by researchers at the University of Bonn and the Bernhard Nocht Institute for Tropical Medicine in Hamburg. Scientists from Brazil, Singapore, South Africa and England have also participated in the study has been published in the journal “PLoS Medicine”.

Hepatitis C affects approximately 170 million people worldwide. The contaminated units of blood are a major source of contamination, they are routinely tested for hepatitis C in Europe and the USA. These recent tests against are too expensive for poorer countries who then turn to testing older and much less sensitive.

Jan Felix Drexler, University of Bonn said: “In Brazil, a test for hepatitis C market costs more than $ 100 per sample. In contrast, ours is up to 19 dollars”. The principle of the method is the same: the test recognized in the blood DNA sequences specific to hepatitis C. It will not only determine whether or not contamination but also to quantify. The test could also help monitor the success of therapy.

News of the pre-Big Bang

Was there a pre-Big Bang? For some, the question is irrelevant: if there was one, it is forever undetectable. For others, on the contrary, the whole issue is that if there was one, could he have left “marks” in our cosmos?

Alejandro Corichi of the National Autonomous University of Mexico and Parampreet Singh, the Perimeter Institute for Theoretical Physics in Waterloo (Ontario) believe that yes: Based on their calculations, they argue that these traces would be detectable in the form of fluctuations in the CMB-explosive remnants of the Big Bang in which bathes the cosmos. Better still, they write, if such traces are actually detectable is that the universe was before we quite similar to ours.

At the base, the two physicists are not marginal in their search for “something” of the pre-Big Bang. They only build their theory from a concept that few of our readers should know: loop quantum gravitational (Loop quantum gravity). The inventor of this concept, which would in theory to rewrite the equations of Einstein to comply with the universe bizarroïde of the small-and time-the Big Bang is the German Martin Bojowald described by Nature in 2005 as one of the leading candidates for the Einstein of the twenty-first century.

When a president mingled AIDS

Posted on 14. Apr, 2008 by in Education in Science, Health & Medicine, Social

The disastrous policy of the South African government to the AIDS caused 330 000 deaths, shows a study from Harvard University.

For years, former President Thabo Mbeki has denied the reality of AIDS: from 2000, he first publicly denied the association between AIDS and HIV-virus, which identified 25 years ago, has earned this year’s Nobel medicine at its discoverer. Then in 2002-2003, against the protests, including in his country, he appeared bend, but has delayed the entry to his country of AIDS drugs. Until 2006, its health minister went so far as to recommend garlic and olive oil as a treatment.

South Africa has one of the highest prevalence of AIDS on its territory, with 5 and a half million people infected, which represents 19% of the adult population. In 2000, President Mbeki had attended a round table of experts, by entrusting the management to a man named Peter Duesberg, California, the most media promoters of the theory that HIV does not cause AIDS. A few months later, at the Annual Conference on AIDS had rightly held that year in his country, it officially announced its rejection of the “theory” of AIDS and at the same time, offers of free drugs, including generic drugs less expensive.

Thabo Mbeki left the presidency last September. (more…)

Philippe Sautet, Silver Medal CNRS 2007

The catalyst for chemistry Lyon
“At the Polytechnic, economics courses and chemistry fascinated me for a very specific reason: through these two disciplines, I discovered modeling. Much more than the technique itself, I was seduced by the idea of being able to extract concepts from numerical models. “Thus, Philippe Sautet became a chemist theorist, his passion for building models to understand and predict real phenomena and complex. In 1988, after a DEA and a PhD in theoretical chemistry, he joined the CNRS and joined the team of Bernard Bigot at the Research Institute for Catalysis of Lyon. There, he began his first work on modeling the catalyst and that is, for nearly twenty years, he developed methods of calculation and theoretical models in order to unravel the mysteries of this property that is the subject of both issues.
