Mayo Clinic researchers and collaborators have validated the zebrafish as a functional model for nicotine addiction research. The findings appear in the Proceedings of the National Academy of Sciences (PNAS). The zebrafish is valuable because it is easy to study and exhibits [...]
Mayo Clinic surgical researchers are reporting a 93 percent success rate in recent animal tests of endoscopic repair of perforated ulcers. The goal is to advance the use of an endoscope — which allows access to organs through natural openings, such as the mouth —
for a less invasive alternative to laparoscopic techniques (surgery performed through [...]
Mayo Clinic researchers have found that certain structural features within breast tissue can indicate a woman’s individual cancer risk. The findings appear online today in the Journal of Clinical Oncology.
The study shows that acini (AS-ih-nye), the small milk-producing elements in breast lobules, can be counted in sample biopsies. The percentage of acini present per lobule [...]

Mayo Clinic researchers report that distress and fatigue among medical residents are independent contributors to self-perceived medical errors. The findings appear today in the Journal of the American Medical Association (JAMA).
“We looked at distress and fatigue together and found that both factors [...]
In a proof-of-concept study, Mayo Clinic investigators have demonstrated that induced pluripotent stem (iPS) cells can be used to treat heart disease. iPS cells are stem cells converted from adult cells. In this study, the researchers reprogrammed ordinary fibroblasts, cells that contribute to scars such as those resulting from a heart attack, converting them into [...]
Mayo Clinic cardiology researchers have found a peptide that helps preserve and improve kidney function during heart failure, without affecting blood pressure. Earlier variations of this peptide caused blood pressure to drop limiting the potential benefits to the kidneys. The findings appear in the current Proceedings of the National Academy of Sciences.
“Heart failure itself and [...]
Ronald Petersen, M.D., Ph.D., head of Mayo’s Alzheimer’s Disease Research Center, is featured in an HBO-produced feature on Mild Cognitive Impairment. Dr. Petersen, a national expert in dementias, is focused on finding ways to make the earliest possible diagnoses for MCI. Dr. Petersen diagnosed President Ronald Reagan’s Alzheimer’s disease. Here’s a sampling:

Mayo Clinic researchers are reporting positive results in early leukemia clinical trials using the chemical epigallocatechin gallate (EGCG), an active ingredient in green tea. The trial determined that patients with chronic lymphocytic leukemia (CLL) can tolerate the chemical fairly well when high doses are administered in capsule form and that lymphocyte count was reduced in [...]
Mayo Clinic and the University of Minnesota researchers have been collaborating on medical research for over five years as part of the Minnesota Partnership for Biotechnology and Medical Genomics. Now they’ve gone from humans to bugs. Investigators have discovered a way to create a human-safe pesticide aimed specifically at aphids that destroy soybeans and other [...]
