LONDON, Jan 2 (Reuters) – Scientists seeking a cure for AIDS
say they have been inspired, not crushed, by a major setback in
which two HIV positive patients believed to have been cured
found the virus re-invading their bodies once more.
True, the news hit hard last month that the so-called
“Boston patients” – two men who received bone marrow transplants
that appeared to rid them completely of the AIDS-causing virus -
had relapsed and gone back onto antiretroviral treatment.
LONDON (Reuters) – Trebling tobacco tax globally would cut smoking by a third and prevent 200 million premature deaths this century from lung cancer and other diseases, researchers said on Wednesday.
In a review in the New England Journal of Medicine, scientists from the charity Cancer Research UK (CRUK) said hiking taxes by a large amount per cigarette would encourage people to quit smoking altogether rather than switch to cheaper brands, and help stop young people from taking up the habit.
LONDON (Reuters) – He was riddled with jaundice, pock-marked, bloody and twitchy.
A new scientific analysis shows French revolutionary Maximilien de Robespierre was probably suffering from an organ-destroying immune disorder called sarcoidosis when he was executed by guillotine in 1794.
LONDON, Dec 20 (Reuters) – People who are already on the way
to developing diabetes could significantly reduce their risk of
having a heart attack or stroke by walking for just an extra 20
minutes a day for a year, scientists said on Friday.
A large international study of people with a condition
called impaired glucose tolerance (IGT) – a precursor to
diabetes – found that taking an extra 2,000 steps a day over one
year cut the risk of serious heart illness by 8 percent.
LONDON (Reuters) – Scientists have found that the sleep disorder narcolepsy can sometimes be triggered by a scientific phenomenon known as “molecular mimicry”, offering a possible explanation for its link to a GlaxoSmithKline H1N1 pandemic flu vaccine.
Results from U.S. researchers showed the debilitating disorder, characterized by sudden sleepiness and muscle weakness, can be set off by an immune response to a portion of a protein from the H1N1 virus that is very similar to a region of a protein called hypocretin, which is key to narcolepsy.
LONDON (Reuters) – Scientists have proved for the first time that the Middle East respiratory syndrome (MERS) virus that has killed 71 people can also infect camels, strengthening suspicions the animals may be a source of the human outbreak.
Researchers from the Netherlands and Qatar used gene-sequencing techniques to show that three dromedary, or one-humped camels, on a farm in Qatar where two people had contracted the MERS coronavirus (CoV) were also infected.
LONDON (Reuters) – Scientists derided research published on Tuesday that suggested ear acupuncture may help people lose weight, saying the study’s design was flawed and its conclusions highly implausible.
Responding to the findings of research published online in the journal Acupuncture in Medicine, experts not involved in the work said it was unreliable and probably a waste of money.
LONDON, Dec 12 (Reuters) – The global death toll from cancer
rose to 8.2 million in 2012 with sharp rises in breast cancer as
the disease tightened its grip in developing nations struggling
to treat an illness driven by Western lifestyles.
Cancer deaths were up 8 percent from 7.6 million in a
previous survey in 2008 and breast cancer killed 522,000 women
last year, up 14 percent in the same period, according to the
World Health Organisation’s International Agency for Research on
LONDON (Reuters) – Scientists have found that a mutation in a new strain of bird flu infecting people in China can render it resistant to a key first-line treatment drug without limiting its ability to spread in mammals.
The discovery means that unlike seasonal flu strains, which often become less transmissible when they develop resistance to drugs like Roche’s Tamiflu, the new H7N9 bird flu does not lose any of its spreading potential with drug resistance.
LONDON (Reuters) – Researchers cast doubt on the prevailing wisdom that vitamin D supplements can prevent conditions like cancer, diabetes and heart disease, saying on Friday low vitamin D may be a consequence, not a cause, of ill health.
The findings could have implications for millions of people who take vitamin D pills and other supplements to ward off illness – Americans spend an estimated $600 million a year on them alone.
