Fatal Copper Disorder Can Now Be Detected At Birth
Fatal Copper Disorder Can Now Be Detected At Birth
A new test could greatly extend the survival of infants with Menkes disease, a rare, otherwise fatal disorder of copper metabolism. The test allows for early diagnosis of the condition, when the chance for successful treatment is greatest.
Bone Marrow Stem Cell Release Regulated By Brain's Biological Clock
Researchers have discovered that the release of blood stem cells from bone marrow is regulated by the brain through the cyclical human biological clock, via adrenergic signals transmitted by the sympathetic nervous system. These new findings point out that the harvest of stem cells for transplantation may be improved by timing it at the peak of their release.
Less Invasive Method Provides Highly Accurate Means To Determine Lung Cancer Stage, Study Suggests
Using two different endoscopes together is better than using one to stage lung cancer, and is also much more precise and less invasive than the surgical method now most commonly used. This new technique, which uses two small flexible tubes, one of which is inserted into a patient's esophagus to access lymph nodes in the back of the lungs while the other is placed into the trachea, or airway, to reach nodes at the front and sides, was 93 percent accurate in finding malignant lymph nodes in a group of 138 patients.
Babies Recently Treated With Lotion, Shampoo, And Powder More Likely To Have Phthalates Chemicals In Urine
Babies recently treated with infant personal care products such as lotion, shampoo, and powder, were more likely to have manmade chemicals called phthalates in their urine than other babies. Phthalates (pronounced "thah-lates") are added to many personal care and cosmetic products, as well many common household plastic and vinyl products, and some studies suggest they may affect reproductive development in humans. Phthalate exposure in early childhood has been associated with altered hormone concentrations as well as increased allergies, runny nose, and eczema.
Birth Control Pill Use Cuts Ovarian Cancer Risk
A new study from The Lancet finds that the longer a woman takes birth control pills, the lower her risk of ovarian cancer.
Bug Guts Map Brings Scientists Closer To Understanding Different Bugs' Role In The Body
Scientists have made a major step towards understanding precisely which bugs in the gut are involved in which processes in the body, by mapping the different species of bugs living in seven members of the same Chinese family.
