In a recent study led by Uppsala University, the researchers compared the DNA of identical (monozygotic) twins of different age. They could show that structural modifications of the DNA, where large or small DNA segments change direction, are duplicated or completely lost are more common in older people. The results may in part explain why the immune system is impaired with age.
New research from Uppsala University, Sweden, shows that reduced insulin sensitivity is linked to smaller brain size and deteriorated language skills in seniors. The findings are now published in the scientific journal Diabetes Care.
New research from Uppsala University shows that a specific brain region linked to appetite regulation is reduced in elderly people who are obese. Poor eating habits over a lifetime may therefore weaken brain function that helps us to control our desire to eat. The findings are published in The International Journal of Obesity.
Newborn mice that are exposed to Bisphenol A develop changes in their spontaneous behavior and evince poorer adaptation to new environments, as well hyperactivity as young adults. This has been shown by researchers at Uppsala University. Their study also revealed that one of the brain’s most important signal systems, the cholinergic signal system, is affected by Bisphenol A.
Environmental toxicants such as dioxins, PCBs, and pesticides can pose a risk for cardiovascular disease. For the first time a link has been demonstrated between atherosclerosis and levels of these kinds of toxicants in the blood. The study, carried out at Uppsala University, is being published online this week in ahead of print in the prestigious journal Environmental Health Perspectives.
