Infants With Rare Genetic Disease Saved by Cord Blood Stem Cells

...l storage diseases. The major barrier to universal newborn screening is building an infrastructure to support widespread testing, she said. The cost of testing itself would be relatively low. Although lysosomal storage diseases are rare ?fewer than 5,000 births combined out of 4 million per year in the U.S....

New Estimates For The Causes Of Child Deaths Worldwide

...ild deaths. Infection of the blood or pneumonia in newborn babies and pneumonia in older children constitute 29% of all deaths. Undernutrition is an underlying cause of 53% of all deaths in children aged younger than 5 years. The investigators also calculated the total numbers and proportional distributions ...

Asymptomatic HIV babies could use earlier treatment

...l trials are needed to determine if every infected newborn should be treated or if some subsets of infants will benefit more than others, Maldonado explained. In the meantime, the findings emphasize the importance of testing pregnant women for HIV and watching for signs of infection in the newborns of women ...

An essential regulator of body weight revealed

...from adult mice. If the neurons were eliminated in newborn mice, their developing brains found a way to compensate for the deficiency, and the mice grew up eating normally. The research, conducted by Serge Luquet at the University of Washington in the laboratory of Howard Hughes Medical Institute investigato...

Study uncovers placental microtransfusions lead to transmission of AIDS virus during childbirth

...become infected themselves. That's a half million newborn worldwide every year facing chronic illness and premature death on their first day out of the safety of the womb. "The question has always been how does the virus get from the mothers to the babies?" said principal investigator Dr. Steven Meshnick, ...

Cells from amniotic fluid used to tissue-engineer a new trachea

...t year, Fauza reported using similar techniques in newborn lambs to repair congenital diaphragmatic hernia (CDH), or a hole in the diaphragm that separates the lungs from the visceral organs. If the hole is large enough, the stomach and other visceral organs can end up in the chest cavity, crowding the lung...

New brain scan technology could save babies' lives

...n some cases help save the lives, of premature and newborn babies in intensive care. By providing vital information about brain function at the cot side, the scanner avoids the need to move critically ill babies to conventional scanning facilities, which may involve sedating them and has a degree of risk.

Greasing interferon's gears may pave way to greater therapeutic benefits, fewer side effects

... Holtzman. The researchers are currently screening newborn infants for levels of Stat1 action and tracking their susceptibility to viral infection. In addition, the group is studying transgenic mice engineered to carry the same Stat1 mutations that were examined in cells. In this way, the researchers can i...

Infants can organise visual information at just four months

...vious observations that this ability is present in newborn babies. At four months, two further grouping abilities emerged: grouping by shape and by proximity. Proximity grouping had not been tested in infants prior to this research, and grouping by shape had previously been seen only at six or seven months. ...

Neurons find their place in the developing nervous system with the help of a sticky molecule

The researchers found that the transplanted myelin-producing cells survived in the mice brains and successfully moved to regions of the brain where they could aid in producing myelin. The transplanted cells also helped lead to production of...

...y. In the 1990s, the same research team found that newborn Siphonops annulatus had teeth and stayed with their mothers for some time after hatching. Those observations, coupled with the unusually pale skin color of mothers caring for young, led Nussbaum and colleagues to speculate that S. annulatus hatchling...
