Estrogen protects male rats from aortic aneurysms

...t, strikes men more often than women. But vascular surgeons at the University of Michigan Medical School have found some intriguing clues. At this week's American College of Surgeons meeting in New Orleans, Derek T. Woodrum, M.D., a U-M resident in general surgery, will present new research results showing th...

Faces age due to fat loss, skin changes - not gravity

...sun exposure, which damages the skin. "Plastic surgeons rejuvenate the aging face by pulling up and tightening the tissue, but treatment also requires a balance between tightening tissue and replacing loss facial fat with wrinkle fillers," said Dr. Lambros. "The key is knowing how much of each to do." ...

Plastic surgeons perform first entire face reconstruction

..., but deep emotional scars, too. A team of plastic surgeons has successfully combined several reconstructive techniques to help burn victims regain some sense of self without undergoing multiple painful procedures and huge scarring often associated with reconstructing the face, according to a study presented ...

To save dolphin's dorsal fin experts combine medical technology and teamwork

...ammal veterinarians, medical researchers, cosmetic surgeons and dolphin trainers recently joined forces to apply the latest advances in human regenerative medicine in an attempt to restore a bottlenose dolphin's damaged dorsal fin. The procedure on Liko, a three-year-old male dolphin at Dolphin Quest on Hawa...

Study is looking at ways to help stroke survivors regain lost motor skills

...ions impaired by stroke damage. In the study, surgeons place a set of small stimulating electrodes on the protective membrane over the outer surface, or cortex, of the brain corresponding to areas of the brain where motor skills were affected by stroke. The electrode connects to a wire running under the...

Stimulating nerve cells with laser precision

...rently, once the proper neural region is selected, surgeons pinpoint the individual nerves by a process of elimination, striking nerves with an electric probe while the patient is awake to ensure that the right nerve has been located. But electrical probes create a halo of electrical activity in surrou...

Study discovers serious deficiencies in 'apparently normal' heart valves

...ven though the leaky mitral valve can be repaired, surgeons have reported that for many patients the mitral regurgitation returns. The changes that we found in the mitral valves could account for these mixed surgical outcomes." Grande-Allen's co-authors include, Allen G. Borowski, Richard W. Troughton, Penny ...

UCSD team discovers specialized, rare heart stem cells in newborns

...Traditionally, pediatric cardiologists and cardiac surgeons have relied on mechanical devices, human and synthetic tissue grafts, and artificial and animal derived valves to surgically repair heart defects. While progenitor cells won't grow a whole new heart, our research has shown that they can spontaneously...

Defining male and female

Of course, social and legal gender assignment still must be carried out at birth." Scientific evidence on gender is revealing an increasin...

Scientists infuse rat spinal cords with brain-derived human stem cells

... Unveiling a delivery method that may one day help surgeons treat the deadly neurodegenerative disease amyotrophic lateral sclerosis (ALS), researchers at the University of Wisconsin-Madison have inserted engineered human stem cells into the spinal cords of ALS-afflicted rats. Reporting their work today (Apri...

Gene variants predict bleeding after heart surgery

...the heart-lung machine to keep blood pumping while surgeons operate on the stopped heart. "However, these risk factors we use now are poorly predictive of which patients are more likely to bleed," Welsby continued. "Also, these factors are only partially successful in accounting for the striking variability i...

Chromosome deletion predicts aggressive neuroblastoma

...s of neuroblastoma are low risk, and resolve after surgeons remove the tumor. Other cases are more aggressive, and are more likely to resist initial treatment, or to cause a relapse. Identifying the correct risk level allows doctors to treat aggressive cancers appropriately, while not subjecting children with...
