New strategy for treating allergic disorders

Ghent - Oral intake of allergens or auto-antigens via the lactic acid bacterium Lactococcus lactis might be a new strategy for treating various kinds of auto-immune and allergic disorders.

Specific microRNA, called miR-21, helps liver cancer develop

New research shows how a particular small molecule blocks the activity of a cancer-suppressing gene, allowing liver-cancer cells to grow and spread.

Delta-9-tetrahydrocannabinol opens door for virus that causes Kaposi's sarcoma

The major active component of marijuana could enhance the ability of the virus that causes Kaposi's sarcoma to infect cells and multiply, according to a team of researchers at Harvard Medical School.

Colon cancer may benefit from hormone replacement therapy

Researchers at the Kimmel Cancer Center at Jefferson in Philadelphia have found new evidence suggesting that colon cancer is actually a disease of missing hormones that could potentially be treated by hormone replacement therapy.

Cell injury caused by brushing may help keep gums healthy

One way regular brushing may help keep gums firm and pink is, paradoxically, by tearing open cells, researchers have found.

Region of brain for processing visual 3D shapes indentified

In studies with monkeys, researchers have identified in detail the brain regions responsible for the unique ability of primates, including humans, to process visual 3D shapes to guide their sophisticated manipulation of objects.

New heart attack test assessed

New research commissioned by the National Institute for Health Research's Health Technology Assessment (NIHR HTA) programme is investigating a new blood test for helping diagnose or rule out heart attacks.

Schizophrenia improved by mental and physical exercise

Scientists at Melbourne's Howard Florey Institute have shown that mental and physical exercise can improve behavioural deficits in schizophrenia and repair damaged chemical transmitter pathways in the brain.

Many different reasons for having sex

Many scientists assume people have sex for simple and straightforward reasons such as to experience sexual pleasure or to reproduce, but new research at The University of Texas at Austin reveals hundreds of varied and complex motivations that range from the spiritual to the vengeful.

Drugs designed to disable enzyme TOPK could have anti-cancer benefits

Working with human colorectal cancer cells, a University of Minnesota team, led by cancer biologists Zigang Dong and Ann Bode, has found the potential culprit among a network of enzymes that relay signals inside cells to regulate such functions as cell growth, cancer development and programmed cell death.

Scientists discover brain cell development process implicated in mental retardation

New Brunswick, N.J. , Scientists at Rutgers, The State University of New Jersey, have discovered a biological process in brain cell development that may help explain some causes of mental retardation.

Lithium promotes better bone healing

Researchers at The Hospital for Sick Children (SickKids) have found a molecular pathway that plays a critical role in bone healing and have found that the drug lithium can improve the healing process.

Reducing inflammation plays key role in type 1 diabetes therapy

Researchers at Beth Israel Deaconess Medical Center (BIDMC) have found that a triple combination therapy consisting of both tolerance-inducing and anti-inflammatory properties is successful in abolishing adverse autoimmunity against insulin-producing cells in a mouse model of Type 1 diabetes.

Neighbor clustering better identifies functionally related genes on the bacterial chromosome

The moment a bacterial pathogen makes contact with its host, its goal is simple: to infect.

New way to predict how cells will respond to targeted drug therapies

Models based on this approach could help doctors make better treatment choices for individual patients, who often respond differently to the same drug, and could help drug developers identify the ideal compounds on which to focus their research.

Nanoparticles may provide safe pain control on the battlefield

University of Michigan scientists have received a pilot grant of nearly $1.3 million from the Defense Advanced Research Projects Agency to test whether nanoparticles can solve a pressing problem in battle zones like Iraq: how to administer sustained, safe doses of the most effective painkillers to injured soldiers, long before they can reach expert medical help.

Pigs key to understanding antibiotic resistant bacteria

NSW Department of Primary Industries (NSW DPI) Immunology & Molecular Diagnostic Research Unit Team Leader, Dr James Chin, says it is commonly believed that each time an antibiotic is used only pathogens or disease-causing bacteria will be killed.

Huntington's disease study shows animal models on target

An international team of researchers has published a benchmark study showing that gene expression in several animal models of Huntington's Disease (HD) closely resembles that of human HD patients.

Baby boomers are starting to feel the aches, pains and weight gain of aging

Because they, like others, want to feel younger for longer, food companies and food researchers are striving to meet their needs. Increased amounts of nutritional supplements and antioxidants, including calcium, vitamin D and zinc, can slow the rate of age-related disease and increase the number of healthy years, according Jeffrey Blumberg, a nutrition scientist at Tufts University and speaker here at the Institute of Food Technologists Annual Meeting & Food Expo.
