How to diagnose and treat Gardner syndrome with gastric polyposis
Gardner syndrome (GS) is a rare, autosomal, dominant inherited disorder with a high degree of penetrance characterized by the triad: intestinal polyposis and various bone and soft-tissue tumors. It is regarded as a clinical subgroup of familial adenomatous polyposis (FAP).   view more (2008-05-21)

Over half of people with rheumatoid arthritis have periodontitis
Over half (56%) of people with rheumatoid arthritis (RA) also have periodontitis (a chronic inflammatory disease of the gum and surrounding ligaments and bones that hold the teeth in place), displaying fewer teeth than healthy matched controls, high prevalence of oral sites presenting dental plaque and advanced attachment loss (the extent of... view more...

Going from ulcers to cancer
Researchers have uncovered a big clue as to why some of the bacteria that cause stomach ulcers pose a greater risk for serious problems like stomach cancer than others; it turns out these bacteria can exploit the surrounding stomach cells to protect them from the immune system.   view more (2008-08-25)

Severe human bite wounds are 12 times more common in men

Genital stimulation opens door for cryptic female choice in tsetse flies
By snipping off parts of male genitalia and reducing genital sensation in both male and female tsetse flies, researchers induced a suite of changes in female reproduction, including reduced ovulation, reduced sperm storage and increased re-mating attempts by the females.   view more (2009-05-15)

Radiation therapy combined with microsurgery shows promise for curing injured spinal cord
Research on rats with crushed spinal cords, similar to human injury, reveals that treatment soon after injury combining radiation therapy to destroy harmful cells and microsurgery to drain excess fluids significantly increases the body's ability to repair the injured cord leading to permanent recovery from injury.   view more (2007-07-25)

Mutation may cause inherited neuropathy
Mutations in a protein called dynein, required for the proper functioning of sensory nerve cells, can cause defects in mice that may provide crucial clues leading to better treatments for a human nerve disorder known as peripheral neuropathy, which affects about three percent of all those over age 60.   view more (2007-12-26)

Scientist refines cosmic clock to determine age of Milky Way
The University of Chicago's Nicolas Dauphas has developed a new way to calculate the age of the Milky Way that is free of the unvalidated assumptions that have plagued previous methods.   view more (2005-06-30)

Stress may leave your mouth a mess
A literature review published in the August issue of the Journal of Periodontology (JOP) saw a strong relationship between stress and periodontal diseases; 57% of the studies included in the review showed a positive relationship between periodontal diseases and psychological factors such as stress, distress, anxiety, depression, and loneliness.   view more (2007-08-09)

Cyclic vomiting syndrome: Recurring and unexplained episodes destroy teeth
Health risks are everywhere and as many as people know about, there are still many of which people are unaware. Parents face even more concerns when it comes to protecting children. Some diseases and problems are more prevalent in children-like cyclic vomiting syndrome (CVS).   view more (2007-01-12)

Why an Allosaurus's butt is worse than its bite
At up to 12 metres long and weighing as much as two tonnes, the Allosaurus is recognised as having been one of the fiercest dinosaurs of the late Jurassic age. But its slender teeth and sometimes narrow jaw bone have left scientists puzzled as to how the Allosaurus managed to hunt prey successfully. Emily Rayfield, of the University of Cambridge's... view more... (2001-02-19)

Argon conclusion: Researchers reassess theories on formation of Earth's atmosphere
Geochemists at Rensselaer Polytechnic Institute are challenging commonly held ideas about how gases are expelled from the Earth. Their theory, which is described in the Sept. 20 issue of the journal Nature, could change the way scientists view the formation of Earth's atmosphere and those of our distant neighbors, Mars and Venus.   view more (2007-09-20)
