Penn Study Details Powerful Molecular Promoter of Colon Cancers
Cancer researchers already know of some oncogenes and other factors that promote the development of colon cancers, but they don’t yet have the full picture of how these cancers originate and spread.
It’s All Connected: Daily Changes in Mouse Gut Bacteria Abundance and Type Moves with Internal Clock and Gender
By now, the old saw, “You are what you eat,” has been well-used in describing the microbiome. However axiomatic that phrase may be, a new study has also found that who and when that consumption is done can affect microbiome make-up.
Penn Study Shows Chronic Insomnia Sufferers May Find Relief with Half of Standard Sleeping Pill Dosing Regimen
The roughly nine million Americans who rely on prescription sleeping pills to treat chronic insomnia may be able to get relief from as little as half of the drugs, and may even be helped by taking placebos in the treatment plan, according to new research published today in the journal Sleep Medicine by researchers from the
Penn Medicine: Cell Aging Slowed by Putting Brakes on Noisy Transcription
Working with yeast and worms, researchers found that incorrect gene expression is a hallmark of aged cells and that reducing such “noise” extends lifespan in these organisms. The team published their findings this month in Genes & Development.
Penn Bioethicists Call for End to "Pay-to-Play" Clinical Research
Charging people to participate in research studies is likely to undermine the fundamental ethical basis of clinical research, according to a new paper written by bioethicists, including lead author Ezekiel Emanuel, MD, PhD, chair of the department of Medical Ethics and Health Policy at the Perelman School of Medicine
Penn Study Questions Presence in Blood of Heart-Healthy Molecules from Fish Oil Supplements
The importance of a diet rich in fish oils – now a billion dollar food-supplement industry -- has been debated for over half a century. A few large clinical trials have supported the idea that fish oils confer therapeutic benefits to patients with cardiovascular disease. Researchers think that hearts and blood vessels may benefit in part from their anti-inflammatory properties.
Sleepy Fruitflies Get Mellow: Sleep Deprivation Reduces Aggression, Mating Behavior in Flies, Penn Study Finds
Whether you're a human, a mouse, or even a fruitfly, losing sleep is a bad thing, leading to physiological effects and behavioral changes. One example that has been studied for many years is a link between sleep loss and aggression. But it can be difficult to distinguish sleep loss effects from stress responses, especially in rodent or human models.
Penn Scientists Find That Flow Means "Go" for Proper Lymph System Development
The lymphatic system provides a slow flow of fluid from our organs and tissues into the bloodstream. It returns fluid and proteins that leak from blood vessels, provides passage for immune and inflammatory cells from the tissues to the blood, and hosts key niches for immune cells. How this system develops hasn’t been well understood, but now researchers from the Perelman School of Medicine at the University of Pennsylvania have found from experiments in mice that the early flow of lymph fluid is a critical factor in the development of mature lymphatic vessels.
Penn Study Finds Link between Physician Training and Brand Name Prescribing
Physicians in training are twice as likely to order a costly brand-name statin (used to lower blood cholesterol levels) when supervised by senior physicians who prefer those medications in their own practice, according to a new study led by researchers at the
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.
