Paracetamol protects against kidney failure
after muscle injury
The commonly-used painkiller Paracetamol can protect against kidney
failure after severe muscle injury, according to researchers at Essex.
One of the main causes of kidney failure affecting tens of thousands of
people each year is Rhabdomyolysis-Induced Renal Failure. Common causes
of this condition include trauma or crushing injuries, drug abuse and
intensive exercise.
Now, an international team of scientists, including Professor Mike
Wilson and Dr Brandon Reeder from the Department of Biological Sciences
at Essex, has discovered that Paracetamol reduces the damage caused to
kidneys following severe muscle injury.
Explained Professor Wilson: ‘It is a very important advance in our
research because it offers the possibility of a very effective, very
simple, very cheap treatment which can be applied in developed and
undeveloped countries.’
The team has previously shown that after severe muscle injury, proteins
such as myoglobin escape into the bloodstream and are deposited in the
kidneys, which generate free-radicals that can damage cells and induce
renal failure. The researchers now report findings in the journal
Proceedings of the National Academy of Sciences that Paracetamol can
mitigate this damage.
It is hoped that Paracetamol may be a very cost-effective way to improve
patient outcomes following such disasters as earthquakes, such as the
recent one in Haiti.
Breakthrough in understanding stress
Scientists at the University have made a breakthrough in
understanding what makes people vulnerable to stress.
A team led by Professor Elaine Fox of the Department of Psychology
tested 100 people and found that, by measuring their biases towards
noticing negative rather than positive images, it was possible to
predict future susceptibility to stress.
This study, funded by the Wellcome Trust, is the first to show that
biases towards negative information make it possible to predict a
physiological reaction to stress up to eight months later.
Professor Fox said: ‘These biases are likely to be reliable early
warning signs for vulnerability to anxiety, and open up possibilities
for therapy.’
Research published a year ago by Professor Fox’s team identified a gene
which is powerfully linked to a tendency to selectively avoid negative
images and to pay attention to positive information.
Professor Fox, Shanna Cahill and Konstantina Zougkou’s latest findings
are published online in the journal Biological Psychiatry.
The results of their research suggest that biases towards noticing
negative things - especially when they operate subconsciously - might
pre-dispose people to anxiety disorders.
In another Wellcome Trust-funded project, Professor Fox’s team is now
investigating whether computer-based training to actively modify these
biases in attention could enhance people’s resilience to traumatic life
events.
Fittest children cycle to school, claims new
research
Children who cycle to school are more physically active and fitter
than those who use other modes of transport, according to new research
from the University.
The findings, published in Medicine and Science in Sports and Exercise,
are based on a study of 6,000 10-16-year-olds from the East of England
whose cardiorespiratory fitness and travel habits were assessed.
Researchers found boys who walked to school were 20 per cent more likely
to be fit compared with those using motorised transport and girls who
walked were 30 per cent more likely to be fit.
Boys who cycled to school were 30 per cent more likely to be fit but
there was a dramatic difference among female cyclists, who were seven
times more likely to reach the minimum fitness standard than girls who
were driven to school.
In all cases, children who were driven to school had the lowest levels
of physical fitness, being less fit than walkers, cyclists and children
who took the bus.
Cyclists were also found to be more physically active at other times of
day when compared with children using other transport modes.
Although cyclists and car users were most different in terms of physical
fitness, the distances they travelled to school were about 1.5 miles for
cyclists and only about two miles for car users. Half of these car
journeys were less than two miles and 15 per cent were less than a mile.
This research by Dr Gavin Sandercock and Christine Voss, of the
University’s Department for Biological Sciences, backs up previous
findings from European countries where cycling is common.
Commenting on their findings, Dr Sandercock said: ‘The positive
associations between active travel and fitness are so strong that
cycling should be encouraged, especially in girls.’
