Early exposure to social deprivation and neglect linked to prematurely shortened telomeres in children

Studies in institutionalized Romanian children have found that the length of time spent in conditions of social deprivation and neglect correlates with lower IQ and behavioral problems. A new study, led by researchers at Children's Hospital Boston and Tulane University, shows that early adversity even affects children's chromosomes – prematurely shortening the chromosome tips, known as telomeres, and hastening how quickly their cells "age."

Cellular 'mechanic' keeps DNA damage in check in cells

CANCER RESEARCH UK scientists have discovered how a protein in immune cells plays an essential role in their development by repairing DNA damage - and if this protein is missing lymphomas can form.

Researchers lay foundation for future lung cancer detection test

Scientists working with Professor Dr. Joachim L. Schultze have identified over 480 molecules whose concentration in the blood changes when a person develops lung cancer. These molecules are present in the blood cells either in increased or decreased quantities. "In lung cancer patients, typical patterns which can be detected with a measuring program thus emerge", explains Prof. Schultze.

Lung protein appears to play a key role in smoking-related emphysema

An international research team has identified a lung protein that appears to play a key role in smoking-related emphysema and have crafted an antibody to block its activity, Indiana University scientists reported.

Inhalation of hydrogen can reduce hyperoxic lung injury

Inhaling small amounts of hydrogen in addition to concentrated oxygen may help stem the damage to lung tissue that can occur when critically ill patients are given oxygen for long periods of time, according to a rat model study conducted by researchers in Pittsburgh. The study also found hydrogen initiates activation of heme-oxygenase (HO-1), an enzyme that protects lung cells.

Over-activation of single gene promotes leukemia, but its loss causes liver cancer

An international team of researchers, led by scientists at the University of California, San Diego School of Medicine, and the Eastern Hepatobiliary Surgery Hospital in China, say a human gene implicated in the development of leukemia also acts to prevent cancer of the liver.

Scientists identify 'de novo' genetic mutations in autism spectrum disorder children

Scientists at the University of Washington (UW) Department of Genome Sciences have identified several sporadic or "de novo" genetic mutations in children with autism spectrum disorder. The researchers applied leading edge molecular biology techniques and massively parallel sequencing to simultaneously examine all of the protein coding portions of the genome, collectively called the exome.

'Mu opioid' receptors in the brain linked to smoking relapse

Nearly everyone who has tried to quit smoking says it's incredibly difficult, and the struggle is due in part to genetic factors. Now, a new study from the Raymond and Ruth Perelman School of Medicine at the University of Pennsylvania sheds light on how one specific genetic risk for smoking relapse may work: Some of the difficulties may be due to how many receptors, called "mu opioid" receptors, a smoker has in his or her brain.

High IGF-I hormone levels linked with better long-term recovery after stroke

Insulin-like growth factor I, IGF-I, is a hormone that is found in the blood and contributes to, among other things, growth and bone mass. The levels of this hormone are higher in people who exercise regularly and those with good health. Scientists at the Sahlgrenska Academy have shown for the first time that high levels of this hormone are associated with better long-term recovery after a stroke.
