Oral bacteria may cause problems in arthritis patients

The culprit behind a failed hip or knee replacements might be found in the mouth. DNA testing of bacteria from the fluid that lubricates hip and knee joints had bacteria with the same DNA as the plaque from patients with gum disease and in need of a joint replacement.

Study explains why some people develop kidney stones and others do not

Kidney stones strike an estimated 1 million Americans each year, and those who have experienced the excruciating pain say it is among the worst known to man (or woman).

Test can reliably diagnose and monitor brain tumor without the need for surgery

In a breakthrough for the way brain cancer is diagnosed and monitored, a team of researchers, lead by Anna M. Krichevsky, PhD, of the Center of Neurologic Diseases at Brigham and Women's Hospital (BWH) in Boston and Santosh Kesari, MD, PhD, director of Neuro-Oncology at UC San Diego Moores Cancer Center, have demonstrated that brain tumors can be reliably diagnosed and monitored without surgery.

BCCA, UBC scientists identify new breast cancer genes

Scientists at the BC Cancer Agency and University of British Columbia have identified new breast cancer genes that could change the way the disease is diagnosed and form the basis of next-generation treatments.

Combined, complimentary therapies maximize NSC transplantation benefits for spinal cord repair

Combined, complimentary therapies have the ability to maximize the benefits of neural stem cell (NSC) transplantation for spinal cord repair in rat models, according to a study carried out by a team of Korean researchers who published in a recent issue of Cell Transplantation.

Conventional testing underestimates Rett Syndrome patients' cognitive abilities

Researchers at Montefiore Medical Center have identified, in a pilot study published in the April edition of Pediatric Neurology, that children with Rett Syndrome, who cannot speak or use their hands to communicate and therefore were thought to be unable to understand and process information, do in fact exhibit meaningful visual search whereby they can process and prioritize information.

Lime juice and solar disinfection improve quality of drinking water

Looking for an inexpensive and effective way to quickly improve the quality of your drinking water? According to a team of researchers from the Johns Hopkins Bloomberg School of Public Health and the Johns Hopkins School of Medicine, sunlight and a twist of lime might do the trick.

New study recommends intraoperative histological evaluation for Hirschsprung disease treatment

Hirschsprung disease occurs when nerve cells in the colon do not develop normally before birth and the bowel is unable to move its contents along. Severe bowel obstruction and even perforation can then occur. The condition is usually diagnosed within the first months of life, but can be found in older children as well.

US DoD awards UC researchers $3.7M grant to study circadian rhythms

Researchers from the University of Cincinnati (UC) have received a four-year, $3.7 million grant from the U.S. Department of Defense for investigations into circadian rhythms that could lead to enhanced understanding of disease treatments, trauma care and human combat performance.

Genetic reach of autism may extend to half siblings

When a child has autism, siblings are also at risk for the disorder. New research from Washington University School of Medicine in St. Louis shows that the genetic reach of the disorder often extends to half siblings as well.

Study demonstrates how Parkinson's disease protein can spread in patient's brain

Last year, researchers from the Perelman School of Medicine at the University of Pennsylvania found that small amounts of a misfolded brain protein can be taken up by healthy neurons, replicating within them to cause neurodegeneration. The protein, alpha-synuclein (a-syn), is commonly found in the brain, but forms characteristic clumps called Lewy bodies, in neurons of patients with Parkinson's disease (PD) and other neurodegenerative disorders.

Genetically modified mouse mimics key features of Charcot-Marie-Tooth disease

A team of scientists from the University of Missouri created a genetically modified mouse that mimics key features of Charcot-Marie-Tooth disease, an inherited neuromuscular disease affecting approximately 150,000 people in the United States.

Kaposi's sarcoma-associated herpesvirus senses and reacts to host cell's impending death

A research team led by Children's National Medical Center has identified a trigger that causes latent Kaposi's sarcoma-associated herpesvirus (KSHV) to rapidly replicate itself. KSHV causes Kaposi's sarcoma, primary effusion lymphoma, and other cancers that commonly affect immunocompromised patients, including those with AIDS.

Engineered particles tied to penetratin discover, deliver ligands for mitochondria, ribosomes

Scientists who developed a technology for identifying and targeting unique protein receptor ZIP Codes on the cellular surface have found a way to penetrate the outer membrane and deliver engineered particles - called iPhage - to organelles inside the cell.

New brain cancer vaccine with material from own tumors proves effective in clinical trial

A new brain cancer vaccine tailored to individual patients by using material from their own tumors has proven effective in a multicenter phase 2 clinical trial at extending their lives by several months or longer. The patients suffered from recurrent glioblastoma multiforme-which kills thousands of Americans every year.

Research on molecular mechanisms underlying Alzheimer's disease

Alzheimer's disease has been described as the "looming epidemic on the horizon." More than 5 million Americans currently suffer from this neurodegenerative disease that robs patients of their memories, and this number is projected to triple by the middle of the century.

Promising anti-diabetic substance found in liquorice root

It provides the raw material for liquorice candy, calms the stomach and alleviates diseases of the airways: liquorice root. Chosen as the "Medicinal plant 2012", the root has been treasured in traditional healing since ancient times. Researchers at the Max Planck Institute for Molecular Genetics in Berlin have now discovered that liquorice root also contains substances with an anti-diabetic effect.

More insight into tangled proteins in Alzheimer's disease

In Alzheimer's disease, brain neurons become clogged with tangled proteins. Scientists suspect these tangles arise partly due to malfunctions in a little-known regulatory system within cells. Now, researchers have dramatically increased what they know about this particular regulatory system in mice. Such information will help scientists better understand Alzheimer's and other diseases in humans and could eventually provide new targets for therapies.

Tumor microenvironment contributes critically to drug response

It should be possible to significantly improve the response of common cancers to existing "classical" chemotherapy drugs, say scientists at Cold Spring Harbor Laboratory (CSHL), by introducing agents that alter the interaction of cancer cells with their immediate surroundings, called the tumor microenvironment.
