'Goldilocks' gene could determine best treatment for TB patients
’Goldilocks’ gene could determine best treatment for TB patients
Tuberculosis patients may receive treatments in the future according to what version they have of a single 'Goldilocks' gene, says an international research team from Oxford University, King's College London, Vietnam and the USA. This is one of the first examples in infectious disease of where an individual's genetic profile can determine which drug will work best for them - the idea of personalised medicine that is gradually becoming familiar in cancer medicine.

Higher intake of processed meat linked to greater type 2 diabetes risk in population with high diabetes rates
Diabetes risk is increased in men and women who eat a diet that is high in processed meats, according to a study published online this week in the American Journal of Clinical Nutrition . Processed meats include hot dogs, lunch meat, sausages and canned meats. The link to type 2 diabetes was even greater for those who regularly ate canned meat.

A silver bullet to beat cancer?
The internet is awash with stories of how silver can be used to treat cancer. Now, lab tests have shown that it is as effective as the leading chemotherapy drug - and may have fewer side-effects. Results from the study at the University of Leeds, published in Dalton Transactions , show that particular silver compounds are as toxic to cancer cells as the platinum-based drug Cisplatin, which is widely used to treat a range of cancers.

Researchers identify peptide that inhibits replication of hepatitis C virus
Researchers identify peptide that inhibits replication of hepatitis C virus
Researchers from UCLA's Jonsson Comprehensive Cancer Center have identified a cell-permeable peptide that inhibits a hepatitis C virus protein and blocks the viral replication that can lead to liver cancer and cirrhosis. The finding by Samuel French, a UCLA assistant professor of pathology and senior author of the research, builds on previous work by French's laboratory that identified two cellular proteins that are important factors in hepatitis C virus infection.

Alzheimer’s Disease May Spread by
For decades, researchers have debated whether Alzheimer's disease starts independently in vulnerable brain regions at different times, or if it begins in one region and then spreads to neuroanatomically connected areas. A new study by Columbia University Medical Center (CUMC) researchers strongly supports the latter, demonstrating that abnormal tau protein, a key feature of the neurofibrillary tangles seen in the brains of those with Alzheimer's, propagates along linked brain circuits, "jumping" from neuron to neuron.

Better NHS services reduce suicide rates
Researchers at The University of Manchester have for the first time shown a positive link between improvements in mental health services and a reduction in suicide rates. Their research is published in The Lancet today (Thursday) in a study by the National Confidential Inquiry into Suicide and Homicide by People with Mental Illness, based at the University's Centre for Mental Health and Risk.

Why the brain is more reluctant to function as we age
Why the brain is more reluctant to function as we age
New findings, led by neuroscientists at the University of Bristol and published this week in the journal Neurobiology of Aging , reveal a novel mechanism through which the brain may become more reluctant to function as we grow older. It is not fully understood why the brain's cognitive functions such as memory and speech decline as we age.

Diabetes – A difficult riddle to solve
Type 2 diabetes has increased at an explosive rate in recent dec- ades and is today one of the most prevalent chronic diseases threat- ening people’s health around the world. The greatest increase has been seen in countries such as India and China, as well as in the Middle East. “We know that people’s genes have not changed in recent decades, so it must be something in the environment, in our lifestyle, that leads to an increasing number of people developing the disease”, says Professor Leif Groop, who works at the Division of Diabetes, Metabolism and Endocrinology at Lund University.

Stem cells could drive hepatitis research forward
By creating liver-like cells, scientists can study why people respond differently to the disease. Hepatitis C, an infectious disease that can cause inflammation and organ failure, has different effects on different people. But no one is sure why some people are very susceptible to the infection, while others are resistant.

Poor neighbourhoods suffer higher incidence of arthritis
People living in poor neighbourhoods have a higher rate and risk of arthritis - one of the most common causes of disability in the developed world. Results revealed that people who live in socially disadvantaged areas were 42 per cent more at risk of getting arthritis than people in more affluent areas.

Genes linked to cancer could be easier to detect with liquid lasers
Genes linked to cancer could be easier to detect with liquid lasers
ANN ARBOR, Mich.-Using a liquid laser, University of Michigan researchers have developed a better way to detect the slight genetic mutations that might predispose a person to a particular type of cancer or other diseases. Their results are published in the current edition of the German journal Angewandte Chemie.

Bacteria evaded childhood vaccine
Bacteria evaded childhood vaccine
Bacteria which can cause pneumonia and meningitis in children swapped DNA to evade a vaccine targeted against them, a new study has found. The researchers from the University of Oxford and the US Centers for Disease Control and Prevention (CDC) used the latest DNA sequencing techniques to investigate how pneumococcus bacteria evolved after the introduction of a childhood vaccine in 2000 in the USA.

Bright Lights of Purity
Luminescence of CdSe/CuS nanocrystals prepared by cation-exchange. On the left are crystals prior to purification, on the right are the same nanocrystals after impurities have been removed. To the lengthy list of serendipitous discoveries - gravity, penicillin, the New World - add this: Scientists with the U.S. Department of Energy (DOE)'s Lawrence Berkeley National Laboratory (Berkeley Lab) have discovered why a promising technique for making quantum dots and nanorods has so far been a disappointment.

Genetic breakthrough for brain cancer in children
Canadian-led research team identifies two mutations in crucial gene involved in deadly pediatric brain tumours An international research team led by the Research Institute of the McGill University Health Centre (RI MUHC) has made a major genetic breakthrough that could change the way pediatric cancers are treated in the future.

Cutting off the oxygen supply to serious diseases
A new family of proteins which regulate the human body's 'hypoxic response' to low levels of oxygen has been discovered by scientists at Barts Cancer Institute at Queen Mary, University of London and The University of Nottingham. The discovery has been published in the international journal Nature Cell Biology .

MS drug prevented fatal heart condition in lab study
A drug used to treat multiple sclerosis may also be effective at preventing and reversing the leading cause of heart attack, a new study has found. Scientists found that Gilenya, a drug recently approved in the US for treating MS, was effective at reversing the symptoms of ventricular hypertrophy in mice.

Body clock receptor linked to diabetes in new genetic study
A study published today has found new evidence for a link between the body clock hormone melatonin and type 2 diabetes. The study found that people who carry rare genetic mutations in the receptor for melatonin have a much higher risk of type 2 diabetes. The findings should help scientists to more accurately assess personal diabetes risk and could lead to the development of personalised treatments.

Protective covering for implants
Protective covering for implants
A new technology could prevent most breast implant rejections. So far, more than a quarter of all breast implants must be removed within four years, because neighboring tissues develop a rigid envelope of fibrous tissue to protect themselves from the foreign body. A company has developed a protective covering made up of a nanostructured surface and a layer of collagen that will prevent the body from rejecting the implant.
