Patients over 50 with ulcerative colitis (UC), a chronic disease of the colon, who undergo surgery to treat their condition live longer than those who are treated with medications, according to a new study from the Perelman School of Medicine at the University of Pennsylvania.
Stem cells are key for the continual renewal of tissues in our bodies. As such, manipulating stem cells also holds much promise for biomedicine if their regenerative capacity can be harnessed. However, understanding how stem cells govern normal tissue renewal is a field still in its infancy.
Hydraulic Fracturing Linked to Increases in Hospitalization Rates in the Marcellus Shale Region, According to Penn Study
Hospitalizations for heart conditions, neurological illness, and other conditions were higher among people who live near unconventional gas and oil drilling (hydraulic fracturing), according to new research from the University of Pennsylvania and Columbia University published this week in PLOS ONE.
Vision-Restoring Gene Therapy Also Strengthens Visual Processing Pathways in Brain, According to Penn Study
Since 2007, clinical trials using gene therapy have resulted in often-dramatic sight restoration for dozens of children and adults who were otherwise doomed to blindness. Now, researchers from the Perelman School of Medicine at the University of Pennsylvania and The Children’s Hospital of Philadelphia (CHOP), have found evidence that this sight restoration leads to strengthening of visual pathways in the brain, published this week in Science Translational Medicine.
The human genome encodes roughly 20,000 genes, only a few thousand more than fruit flies. The complexity of the human body, therefore, comes from far more than just the sequence of nucleotides that comprise our DNA, it arises from modifications that occur at the level of gene, RNA and protein.
A scar might be a reminder of an accident or surgery, but the fibrous tissue that makes up a scar also forms after a heart attack and arises in solid tumors as well as in chronic diseases such as liver cirrhosis and muscular dystrophy. Implanted medical devices and materials are similarly surrounded by fibrous capsules that impede their function.
Mathias Basner of the Perelman School of Medicine is interviewed about sleep deprivation, the relationship between work and sleep and other topics about the science of sleep.
Remediating Abandoned, Inner City Buildings Reduces Crime and Violence in Surrounding Areas, Penn Study Finds
Fixing up abandoned buildings in the inner city doesn’t just eliminate eyesores, it can also significantly reduce crime and violence, including gun assaults, researchers from the University of Pennsylvania and Penn’s Perelman School of Medicine report in the first study to demonstrate the direct impact of building remediation efforts on crime.
Affordable Care Act Results in Dramatic Drop in Out-of-Pocket Prices for Prescription Contraceptives, Penn Medicine Study Finds
Average out-of-pocket spending for oral contraceptive pills and the intrauterine device (IUD), the two most common forms of contraception for women, has decreased significantly since the Affordable Care Act (ACA) took effect.
