New model for preserving donor tissue will allow more natural joint repair for patients

James Cook, director of MU's Comparative Orthopaedic Laboratory and the Missouri Orthopaedic Institute's Division of Research, and James Stannard, J. Vernon Luck Sr. Distinguished Professor of Orthopaedic Surgery at the MU School of Medicine and medical director of the Missouri Orthopaedic Institute.Currently, doctors have to throw away more than 80 percent of donated tissue used for joint replacements because the tissue does not survive long enough to be transplanted. Now, following...

Early exposure to antidepressants affects adult anxiety and serotonin transmission

This image shows Anne M. Andrews, University of California - Los Angeles Health Sciences. A UCLA team has studied early developmental exposure to two different antidepressants, Prozac and Lexapro, in a mouse model that mimics human third trimester medication exposure. They found that, although these serotonin-selective reuptake inhibiting antidepressants (SSRIs) were thought to work the same way, they did not produce the same long-term changes in anxiety behavior in the adult mice.About 15 percent of women in the United States suffer from anxiety disorders and depression during their pregnancies, and many are prescribed antidepressants. However little is known about how early...

Probing bacterial resistance to a class of natural antibiotics

Yixin Shi is a researcher at the Biodesign Institute's Center for Infectious Diseases and Vaccinology.Antimicrobial peptides are a distinctive class of potent, broad-spectrum antibiotics produced by the body's innate immune system -- the first line of defense against disease-causing microbes.

Potential new tool for cervical cancer detection and diagnosis

This shows a comparison between the normal cervical tissue and tissue lesion for different stages. From top to bottom are the pathological images for the normal cervical tissue (first row) and tissue lesion (second row), the photo image (third row) and corresponding DMAP images (fourth row) of representative experiments respectively. Margins of the normal tissue (green) and cervical lesion (red) are indicated in the photo and DAMP images. The scale bar for the histological images represents 0.1 mm, and that for the photo and DMAP images is 1 mm.Cervical cancer is, in many ways, a shining example of how successful the war on cancer can be. Thanks largely to the advent of Pap smear screening, U.S. cervical cancer...
