Research provides new insights into how cilia are assembled on the cell surface

Body cells detect signals that control their behavior through tiny hairs on the cell surface called cilia. Serious diseases and disorders can result when these cilia do not work properly.

Skin cell-derived CGRP-beta may cause chronic pain

A new study may explain why only 50% of patients experiencing chronic nerve pain achieve even partial relief from existing therapeutics. The study, published in the June 6 online version of the international research journal PAIN, reveals that certain types of chronic pain may be caused by signals from the skin itself, rather than damage to nerves within the skin, as previously thought.

More women than men are unnecessarily referred for nuclear stress tests

New research from cardiologists at Rhode Island and The Miriam hospitals suggests a possible gender disparity in how patients are referred for nuclear stress tests, an imaging technique that measures blood flow to the heart muscle both at rest and during periods of stress, such as exercise.

Insight into how cancer cells acquire selective survival advantage

Research led by David Litchfield of The University of Western Ontario has identified how biochemical pathways can be "rewired" in cancer cells to allow these cells to ignore signals that should normally trigger their death. It's one way that cancer cells may become resistant to therapy.

Decline of citrate concentration may contribute to bone brittleness

Bone is one of nature's surprising "building materials." Pound-for-pound it's stronger than steel, tough yet resilient. Scientists at the U.S. Department of Energy's Ames Laboratory have identified the composition that gives bone its outstanding properties and the important role citrate plays, work that may help science better understand and treat or prevent bone diseases such as osteoporosis.

Eliminating ABCB5-expressing cells crucial for successful colorectal cancer treatment

Researchers at Children's Hospital Boston have found a marker called ABCB5 that both tags a small proportion of cells within colorectal cancers and fuels resistance in those cells to standard treatments. The results indicate that eliminating ABCB5-expressing cells is crucial for successful colorectal cancer treatment, while adding to the growing body of evidence for a theory of cancer growth called the cancer stem cell hypothesis.

Medical management preferred over surgery for pediatric orbital cellulitis

Researchers from Hasbro Children's Hospital in Providence, R.I., report that medical management may be preferred over surgery for children with orbital cellulitis, an acute infection of the tissues surrounding the eye. They have determined the criteria for surgical intervention should be dependent upon the size of a subperiosteal abscess (SPA).

High-fat diet may cause brain nerve cell injury

Obesity among people who eat a high-fat diet may involve injury to neurons, or nerve cells, in a key part of the brain that controls body weight, according to the authors of a new animal study. The results will be presented Tuesday at The Endocrine Society's 93rd Annual Meeting in Boston.

Rockefeller, Scripps Research develop first genetically humanized mouse model for hepatitis C

Scientists at Rockefeller University and The Scripps Research Institute have developed the first genetically humanized mouse model for hepatitis C, an achievement that will enable researchers to test molecules that block entry of the hepatitis C virus into cells as well as potential vaccine candidates. The finding is reported in the June 9 issue of the journal Nature.
