(Press-News.org) London, UK, Saturday 12 April 2014: Exciting new data presented today at the International Liver Congress™ 2014 shows that the gut microbiota has a potential role in the development of alcoholic liver disease (ALD).1 Though an early stage animal model, the French study highlights the possibility of preventing ALD with faecal microbiota transplantation – the engrafting of new microbiota, usually through administering human faecal material from a healthy donor into the colon of a recipient.2
In the study, two groups of germ-free mice received gut microbiota transplants from human representatives; one set from a patient with severe alcoholic hepatitis, the other from a patient with a history of alcohol abuse but
without alcoholic hepatitis. The two sets of germ-free mice were then fed a liquid alcoholic diet.
The group that received microbiota from the patient with severe alcoholic hepatitis developed a more severe
liver injury and a higher disruption of the intestinal mucosa in direct comparison to the group that received microbiota from the patient without severe alcoholic hepatitis. The study also identified two Clostridium bacteria that were able to produce ethanol in vitro and that were systematically associated with intestinal microbiota associated liver injury.
EASL Scientific Committee Member Prof. Frank Lammert commented: "Among heavy drinkers, the severity of alcoholic liver disease does not strictly correlate with the amount of alcohol intake, meaning that other factors must be influencing its development."
"These findings provide first evidence for a causal role of gut microbiota in alcohol-induced inflammation, and open up new avenues for the treatment of alcoholic liver disease with potentially better patient outcomes."
At present, intestinal microbiota is considered to constitute a "microbial organ": one that has pivotal roles in the body's metabolism as well as immune function. Therefore transplantation aims to restore gut functionality and re-establish the homoestasis of intestinal flora.
The study was developed by an INRA-Micalis and INSERM/Paris-South University/Antoine-Béclère hospital
collaboration.

Low vitamin D linked to fatty liver disease in UK children
2014-04-12
London, UK, Saturday 12 April 2014: A UK study[i] investigating the link between low vitamin D status and non-alcoholic fatty liver disease (NAFLD) in British children has identified a genetic variant associated with the disease's severity.
The research, conducted by the King's College Hospital Paediatric Liver Centre and the University of Surrey's School of Biosciences and Medicine, and funded by the Children's Liver Disease Foundation retrospectively analysed the medical records of 120 paediatric patients with NAFLD.
The findings could carry significant implications ...

"Human hepatocellular carcinoma is one of the most prevalent cancers worldwide and the second most frequent cause of cancer-related death," said EASL's Scientific Committee Member Dr Helen Reeves Senior Lecturer & Honorary Consultant Gastroenterologist at Newcastle Hospitals NHS Foundation Trust, ...
New interferon-free, all-oral 3D regimen achieves high SVR in chronic HCV genotype 1 patients
2014-04-12
London, UK, Saturday 12 April 2014: The new interferon-free, all-oral, three direct-acting-antiviral (3D) treatment regimen in development by AbbVie has achieved very high rates of virological response in patients chronically infected with hepatitis C virus (HCV) genotype 1 (GT1); according to the results of three studies presented today at the International Liver CongressTM 2014.
The 3D regimen consists of the HCV NS3/4A protease inhibitor ABT-450 dosed with ritonavir, the NS5A inhibitor ABT-267, and the NS5B RNA polymerase inhibitor ABT-333.
"Using this investigational ...
New data for HCV genotype 4 patients with simeprevir- and sofosbuvir-based regimens
2014-04-12
London, UK, Saturday 12 April 2014: Results from RESTORE , a phase III, multicentre, single-arm, open-label study presented today at the International Liver CongressTM 2014 showed that simeprevir 150 mg once-daily for 12 weeks in combination with peginterferon and ribavirin (followed by 12 or 36 weeks of peginterferon and ribavirin) was effective and well tolerated in hepatitis C virus (HCV) genotype 4-infected patients, consistent with previous observations in HCV genotype 1-infected patients.
Overall, 65.4% of patients achieved SVR12 (82.9% of treatment-naïve, 86.4% ...

The Lancet Oncology today [Friday 11 April] publishes a major new Commission examining the challenges to effective cancer control in China, India, and Russia – which together experience 46% of all new cancers worldwide, and account for more than half (52%) of all cancer deaths globally. The Commission was led by Professor Paul Goss, of Harvard Medical School and Massachusetts General Hospital Cancer Center, USA, in collaboration with over 40 leading cancer experts from the regions studied, and across the world.
At the same time, the journal also publishes a three part ...
UAlberta researchers examine metabolism in defective cells
2014-04-11
UAlberta researchers are taking a closer look at how two metabolic pathways interact to increase the lifespan of cells with mitochondrial defects. Magnus Friis is the lead author of the study, which was published online on April 10 and will be published in the April 24 issue of Cell Reports.
Mitochondria produce energy for cells through oxidative metabolism, but the process produces toxic byproducts that can accumulate and cause defects in the cell's mitochondria. These defects, in turn, affect the cell's ability to generate energy and can potentially lead to cell death ...

2014-04-11
TORONTO, April 11, 2014 – Women with diabetes are 14 per cent less likely to be screened for breast cancer compared to women without diabetes, according to a study by researchers at the Institute for Clinical Evaluative Sciences (ICES) and Women's College Hospital.
The study, published today in the journal Diabetic Medicine, is the first to examine the influence of socioeconomic status on the gap in mammogram screening among women with diabetes.
"Managing the demands of a chronic condition such as diabetes is challenging for many women, leaving other preventative actions, ...
BLOODHOUND team predicts the impact of the 1,000 mph supersonic car
2014-04-11
10th of April, 2014 (London). A new paper from the Swansea University, College of Engineering team working on the BLOODHOUND SSC (Supersonic car) project has been published on the aerodynamic characteristics of travelling at 1,000mph. Simulations have looked at how the car will cope with the supersonic rolling ground, rotating wheels and resulting shock waves in close proximity to the test surface at the record attempt site in Hakskeen Pan, South Africa. Where, in 2015, it will make high speed test runs of up to 800mph, with the full 1,000mph attempt scheduled for 2016.

Odds that global warming is due to natural factors: Slim to none
2014-04-11
An analysis of temperature data since 1500 all but rules out the possibility that global warming in the industrial era is just a natural fluctuation in the earth's climate, according to a new study by McGill University physics professor Shaun Lovejoy.
The study, published online April 6 in the journal Climate Dynamics, represents a new approach to the question of whether global warming in the industrial era has been caused largely by man-made emissions from the burning of fossil fuels. Rather than using complex computer models to estimate the effects of greenhouse-gas ...
Warming climate has consequences for Michigan's forests
2014-04-11
HOUGHTON, Mich., April 11, 2014 – In the last 100 years, Michigan has become warmer, with more rain coming through heavy downpours. Climate models suggest that the state will continue to warm and variability in precipitation patterns will increase, which will have consequences for the state's forests. A new U.S. Forest Service report describes the potential risks and opportunities of climate change for forests in the eastern Upper Peninsula and northern Lower Peninsula.
More than 30 scientists and forest managers contributed to "Michigan Forest Ecosystem Vulnerability ...
