This is the question asked by a team of investigators from the Harvard School of Public Health and the University of Puerto Rico, reporting their findings today during the 87th General Session of the International Association for Dental Research, convening at the Miami Beach Convention Center.
A team of researchers from the Massachusetts General Hospital Center for Engineering in Medicine (MGH-CEM) has found the first evidence of cell-to-cell communication by amino acids, the building blocks of proteins, rather than by known protein signaling agents such as growth factors or cytokines.
A team of scientists from The Ohio State University has examined the stress levels of parents whose young children either had no cavities or so many cavities that the children had receive anesthesia before undergoing dental treatment.
The investigators presented their findings today during the 87th General Session of the International Association for Dental Research.
Today, during the 87th General Session of the International Association for Dental Research, convening at the Miami Beach Convention Center, a group of scientists from Nihon University (Tokyo, Japan) will present findings suggesting that periodontal disease could act as a risk factor for reactivating latent HIV-1 in affected individuals.
BUFFALO, N.Y. -- Several studies have suggested there is a connection between organisms that cause gum disease, known scientifically as periodontal disease, and the development of heart disease, but few studies have tested this theory.
The beneficial effects of anti-angiogenesis drugs in the treatment of the deadly brain tumors called glioblastomas appear to result primarily from reduction of edema - the swelling of brain tissue - and not from any direct anti-tumor effect, according to a study from Massachusetts General Hospital (MGH) researchers.
Bacteria are single cell organisms with no nervous system or brain. So how do individual bacterial cells living as part of a complex community called a biofilm "decide" between different physiological processes (such as movement or producing the "glue" that forms the biofilm)?
In the fight against infected skin wounds, mixing tea tree oil and silver or putting them in liposomes, (small spheres made from natural lipids), greatly increases their antimicrobial activity and may minimise any side effects.
Soldiers who survive severe injuries on battlefields such as those in Iraq and Afghanistan can be at risk from developing infections of their wounds with multidrug resistant bacteria.
Gas gangrene, the notorious infectious disease of two world wars can still be a problem today.
Antibiotics used extensively in intensive livestock production may be having an adverse effect on agricultural soil ecosystems.
A new, environmentally friendly coating that protects metals against corrosion in seawater has been developed by a team of researchers from Sheffield Hallam University.
Drug-resistant forms of HIV can be spread between individuals who have not received anti-retroviral treatment, according to Professor Deenan Pillay from University College, London and the Health Protection Agency, speaking at the Society for General Microbiology meeting at Harrogate today, (Monday 30 March).
A research team at the Scripps Research Institute has obtained the first glimpse of a protein that keeps certain substances, including many drugs, out of cells. The protein, called P-glycoprotein or P-gp for short, is one of the main reasons cancer cells are resistant to chemotherapy drugs. Understanding its structure may help scientists design more effective drugs.
At a time of heightened concern about conflicts of interest posed by relationships between academic medical researchers and commercial firms, a new study finds that a significant number of academic institutions do not have clear policies covering the industrial relationships of members of Institutional Review Boards (IRBs), committees charged with ensuring that clinical studies uphold patient r
