Cell transplantation of lung stem cells has beneficial impact for emphysema

Mesenchymal stem cells are considered for transplantation because they are readily available, highly proliferative and display multi-lineage potential.When autologous, lung-derived mesenchymal stem cells were transplanted endoscopically into 13 adult female sheep modeled with emphysema, post-transplant evaluation showed evidence of tissue regeneration with increased blood perfusion and extra...

Drug might protect hearts of childhood leukemia survivors

About 75 percent of children with leukemia who take chemotherapy face life-threatening heart problems as they age, but an international study led by a University of Rochester Medical Center investigator shows that giving a cardio-protective drug during cancer treatment may prevent the damage.

Excessive endurance training can be too much of a good thing, research suggests

Recent research suggests that chronic training for, and competing in, extreme endurance exercise such as marathons, iron man distance triathlons, and very long distance bicycle races may cause structural changes to the heart and large arteries, leading to myocardial injury. A study in the June issue of Mayo Clinic Proceedings reviews the literature and outlines in detail for the first time the...

Export extravaganza

In the first comprehensive census of human cells' export workers, scientists at EMBL Heidelberg, found an unexpected variety of genes involved in transporting molecules to the cell membrane and beyond. The work is published online today in Nature Cell Biology.

Facebook photos may reflect unconscious cultural differences

The photos we select for our Facebook profiles may reflect individual preferences, but they also appear to reflect more deeply rooted, unconscious cultural differences. That's according to a study conducted in part by researchers at the UT Dallas Center for Vital Longevity.

Filming life in the fast lane

New microscope enabled scientists at EMBL Heidelberg to film a fruit fly embryo, in 3D, from when it was about two-and-a-half hours old until it walked away from the microscope as a larva.

Fossil discovery sheds new light on evolutionary history of higher primates

An international team of researchers has announced the discovery of a new fossil primate from Myanmar that illuminates a critical step in the evolution of early anthropoids. Afrasia closely resembles another early anthropoid, Afrotarsius libycus. The close similarity indicates that early anthropoids colonized Africa only shortly before the time when these animals lived. This was a pivotal step in...

Genetics, rapid childhood growth and the development of obesity

A 38-year longitudinal study of New Zealanders suggests that individuals with higher genetic risk scores were more likely to be chronically obese in adulthood, according to a report published in the June issue of Archives of Pediatrics & Adolescent Medicine, a JAMA Network publication.
