Penn researchers discover pathway that eliminates genetic defects in red blood cells
...s. For example, the most well-described pathway is one
that recognizes nonsense mutations that result in an RNA that makes a protein that is too short. Duchenes muscular dystrophy and cystic fibrosis are examples of hereditary diseases that result from nonsense mutations. We describe a surveillance pa...
Developing a more effective vaccine for tuberculosis

third of the world's population. Although the currently used vaccine (M. bovis BCG) provides young children with protection from tuberculosis, it is not effective at preventing the type of tuberculosis that most adolescents and adults suffer from. Th...
Progesterone therapy and preterm birth: More evidence helps identify women who can benefit

large multi-center trial led by Eduardo B. Fonseca, M.D., women with short cervix (most of whom had no prior history of preterm birth) who received progesterone suppository treatment between 24 and 34 weeks gestation had a greatly reduced rate of pre...

New study demonstrates important role of glia in circadian timing

of the commonly studied rhythmic behaviors observed in Drosophilalocomotor activity. Not only do our studies indicate that Ebony abundance is under clock control, Jackson says, but they also suggest that Ebony may exert its effects on locomotor activ...
Forsyth scientists gain new understanding of adult stem cell regulation
...of adult stem cells in vivo. They showed that when one
of many specific gap junction channel types was abolished, the adult stem cell pool disappeared along with the regenerative capabilities, suggesting that gap junction-permeable signals are necessary to maintain stem cell state and tissue regeneration...
Molecule blocks gene, sheds light on liver cancer
...nked to cancer. These findings show exactly how one
specific microRNA, called miR-21, helps cancer develop. This molecule occurs at unusually high levels in many kinds of cancer cells. The study looked at a gene called PTEN (pronounced P-TEN), which normally protects cells from becoming cancerous. ...

billionth of a meter, or a millionth of a millimeter). For comparison, red blood cells are ten to 100 times larger. The researchers were able to control the nanoparticle size by varying the amount or composition of solvents they used to form the nano...

American buffalo slaughter fueled by international trade
