High beef consumption during pregnancy may affect son's sperm count
2 April 2007 - by Dr Laura Bell
Recent research published in the journal Human Reproduction found that men whose mothers had eaten a lot of beef during pregnancy were three times more likely to have a sperm count so low that they could be classed as sub-fertile. The study, carried out at the... [Read More]
Body clock gene clue in bipolar disorder
26 March 2007 - by Dr Laura Bell
Recent research published in the journal Proceedings of the National Academy of Sciences shows that the disruption of a gene known to regulate the body clock and circadian rhythms in mice triggers behaviours similar to humans with bipolar disorder (previously called manic depression). Bipolar disorder is... [Read More]
Children of long-lived parents have a lower risk of heart disease
19 March 2007 - by Dr Laura Bell
Recent research published in the Archives of Internal Medicine suggests that middle aged people who have parents of which at least one lives to be 85 or more, have a lower risk of heart disease. The research used data from the Framingham Heart Study (FHS), which... [Read More]
Low-fat dairy food may increase risk of infertility
5 March 2007 - by Dr Laura Bell
New research published in the journal Human Reproduction has found that consuming low-fat dairy food may lead to a higher risk of infertility. The study found no difference between women who ate the most dairy food and those who ate little or none. However, differences in... [Read More]
Autism Genome Project identifies novel risk genes
26 February 2007 - by Dr Laura Bell
Recent research published online in the journal Nature Genetics has revealed new genetic variations which may contribute to autism. Autism, along with related conditions such as Asperger syndrome, is characterised by a range of severity and symptoms. The conditions are therefore collectively known as autistic spectrum...

Key type 2 diabetes genes identified
19 February 2007 - by Dr Laura Bell
Recent research published online in the journal Nature has mapped the most important genes involved in increasing people's risk of developing type 2 diabetes. These genes could account for up to 70 per cent of the genetic risk of developing the disorder. Type 2 diabetes affects... [Read More]
Gene linked to Alzheimer's disease development
22 January 2007 - by Dr Laura Bell
By Dr Laura Bell: New research published early online in the journal Nature Genetics has linked mutations in the SORL1 gene with an increased risk of developing Alzheimer's disease. Alzheimer's disease is a progressive, degenerative and irreversible brain disorder that causes intellectual impairment, disorientation and eventually death. It is estimated... [Read More]
Shortened telomeres linked to increased heart disease risk
15 January 2007 - by Dr Laura Bell
New research published in the Lancet medical journal last week shows a potential new way to identify people who have a higher risk of heart disease. Telomeres are the strands of DNA that cap and protect our chromosomes. They act as a kind of cellular clock... [Read More]
Variable gene expression seen in different ethnic groups
15 January 2007 - by Dr Laura Bell
By Dr Laura Bell: Research published in the journal Nature Genetics last week showed that variation between different ethnic groups, such as susceptibility to certain diseases, may be explained by variable gene expression. Samples collected for the International HapMap Project were used in the study. The HapMap was published last... [Read More]
Gene mutation blocks pain
18 December 2006 - by Dr Laura Bell
Research published in the journal Nature last week has pinpointed a mutated form of a gene which prevents carriers from feeling pain. It is hoped the research might offer potential new ways to treat severe pain. The research, carried out by Dr Geoffrey Woods, from the... [Read More]
