Prevent periodontitis to reduce the risk of head and neck cancer
Chronic periodontitis, a form of gum disease, is an independent risk factor for head and neck squamous cell carcinoma. This suggests the need for increased efforts to prevent and treat periodontitis as a possible means to reduce the risk of this form of cancer. view more (2009-09-08)
Dental device gets the measure of sensitive teeth
An innovative device that painlessly detects and measures tooth sensitivity is being commercially developed by a University of Leeds company. D-Sense Ltd, launched this week, backed by an initial £250,000 equity investment by the White Rose Technology Seedcorn Fund (WRTSF). The device is based on a diagnostic technique patented by Professor... view more... (2002-03-01)
Trans fats hinder multiple steps in blood flow regulation pathways
Partially hydrogenated vegetable oils in processed foods contain trans fatty acids that interfere with the regulation of blood flow. A new report reveals a new way in which these "trans fats" gum up the cellular machinery that keeps blood moving through arteries and veins. view more (2009-06-17)
Cigarette smoking nearly doubles risk for root canal treatment
According to a new study appearing in the April issue of the Journal of Dental Research, cigarette smoking can lead to not only tooth discoloration and gum disease, but also a common dental procedure that helps to heal a diseased tooth-the root canal. view more (2006-02-24)
Sexual chemistry: The science exposed… The Biochemist April 2002 issue
The rise and rise of STIs (p.8) More cases of sexually transmitted infections (STIs) are being reported than ever before — the incidence has doubled in young people since 1995. A recent article in The Times described the scene in one central London genito-urinary medicine (GUM) clinic as being “about as quiet as the M25 in rush... view more... (2002-04-03)
Two cardiovascular proteins pose a double whammy in Alzheimer's
Researchers have found that two proteins which work in tandem in the brain's blood vessels present a double whammy in Alzheimer's disease. view more (2008-12-22)
African sweetener
One present-day form of colonialism works like this: A company sends researchers into the rainforest to discover promising new natural substances. Once found, the company registers a patent or trademark and begins to cash-in. Even more effective is the latest variant: Instead of using the plant itself, the relevant gene is isolated and... view more... (2004-01-05)

Renegade RNA — Clues to cancer and normal growth
Researchers at Johns Hopkins have discovered that a tiny piece of genetic code apparently goes where no bit of it has gone before, and it gets there under its own internal code. view more (2007-01-05)
Scripps research study reveals mechanism behind nicotine dependency
The new study reveals that, in rats, chronic nicotine use recruits a major brain stress system, the extrahypothalamic corticotropin releasing factor (CRF) system, which contributes to continued tobacco use by exacerbating anxiety and craving upon withdrawal. The researchers found that administering a compound that blocked the receptors involved in... view more... (2007-10-02)
Grow Your Own Teeth
People who have lost or damaged teeth could soon be growing their own, thanks to a major scientific breakthrough by a start-up, Odontis Ltd, formed by King's College, London. An investment of £400,000 from NESTA (the National Endowment for Science, Technology and the Arts) - the organisation that nurtures UK creativity and innovation and the... view more... (2004-04-30)
U-M research: New plastic is strong as steel, transparent
By mimicking a brick-and-mortar molecular structure found in seashells, University of Michigan researchers created a composite plastic that's as strong as steel but lighter and transparent. view more (2007-10-05)
NYU dental researchers find link between C-section delivery and higher risk of cavities in newborns
A new study by NYU dental researchers suggests that women with dental caries (cavities) who deliver Caesarean-section babies should pay special attention to their newborns' oral health. view more (2005-08-24)
