Physicians have known for decades that many premature babies suffer respiratory problems stemming from insufficiency of a lung substance called surfactant during their first few weeks of life. The standard treatment has been to provide replacement surfactant immediately after birth. A new study has found that even after infants begin producing their own surfactant, it often fails to function properly in premature infants who continue to have lung disease after their first week.
The study also raises the question of whether additional replacement surfactant treatment may benefit such infants, just as it does in the week after birth.
Neonatology researchers from The Childrens Hospital of Philadelphia and the University of Pennsylvania published the study in the October 20 online edition of the journal Pediatric Research. It was the first study of surfactant dysfunction in infants beyond the first week of life. "We studied premature babies who require mechanical ventilation to breathe after one week of age," said Philip L. Ballard, M.D., Ph.D., director of Neonatology Research at The Childrens Hospital of Philadelphia. "We found that three-quarters of these high-risk infants have episodes of surfactant dysfunction, and these episodes are associated with worsening of their respiratory status."

University of Connecticut researchers have created a biodegradable composite made of silk fibers that can be used to repair broken load-bearing bones without the complications sometimes presented by other materials.
Repairing major load-bearing bones such as those in the leg can be a long and uncomfortable process.
Study published in the journal ACS Applied Materials & Interfaces is the outcome of an international effort that included teams from Dresden and Berlin in Germany, and the US.

Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.

Stable joint cartilage can be produced from adult stem cells originating from bone marrow. This is made possible by inducing specific molecular processes occurring during embryonic cartilage formation, as researchers from the University and University Hospital of Basel report in the scientific journal PNAS.
Certain mesenchymal stem/stromal cells from the bone marrow of adults are considered extremely promising for skeletal tissue regeneration. These adult stem...
