Time of day matters to thirsty trees, U of T researcher discovers
The time of day matters to forest trees dealing with drought, according to a new paper produced by a research team led by Professor Malcolm Campbell, University of Toronto Scarborough's vice-principal for research and colleagues in the department of cell and systems biology at the St. George campus.   view more (2009-11-24)

Multiple health concerns surface as winter, vitamin D deficiences arrive
A string of recent discoveries about the multiple health benefits of vitamin D has renewed interest in this multi-purpose nutrient, increased awareness of the huge numbers of people who are deficient in it, spurred research and even led to an appreciation of it as "nature's antibiotic."   view more (2009-11-24)

Factors from common human bacteria may trigger multiple sclerosis
Current research suggests that a common oral bacterium may exacerbate autoimmune disease. The related report by Nichols et al, "Unique Lipids from a Common Human Bacterium Represent a New Class of TLR2 Ligands Capable of Enhancing Autoimmunity," appears in the December 2009 issue of The American Journal of Pathology.   view more (2009-11-24)

Exposure to both traffic, indoor pollutants puts some kids at higher risk for asthma later
New research presents strong evidence that the "synergistic" effect of early-life exposure to both outdoor traffic-related pollution and indoor endotoxin causes more harm to developing lungs than one or the other exposure alone.   view more (2009-11-24)

Surface bacteria maintain skin's healthy balance
On the skin's surface, bacteria are abundant, diverse and constant, but inflammation is undesirable. Research at the University of California, San Diego School of Medicine now shows that the normal bacteria living on the skin surface trigger a pathway that prevents excessive inflammation after injury.   view more (2009-11-23)

New findings suggest strategy to help generate HIV-neutralizing antibodies
New discoveries about anti-HIV antibodies may bring researchers a step closer to creating an effective HIV vaccine, according to a new paper co-authored by scientists at the Vaccine Research Center of the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health.   view more (2009-11-20)

Sweet -- sugared polymer a new weapon against allergies and asthma
Scientists at Johns Hopkins and their colleagues have developed sugar-coated polymer strands that selectively kill off cells involved in triggering aggressive allergy and asthma attacks.   view more (2009-11-20)

UAB Researchers Discover Antibody Receptor Identity, Propose Renaming Immune-System Gene
Researchers at the University of Alabama at Birmingham (UAB) have uncovered the genetic identity of a cellular receptor for the immune system's first-response antibody, a discovery that sheds new light on infection control and immune disorders.    view more (2009-11-20)

New culprit for viral infections among elderly -- an overactive immune response
Researchers at Yale School of Medicine have found that exaggerated responses of the immune system explain why the elderly succumb to viral infections more readily than younger people.   view more (2009-11-19)

Saliva proteins change as women age
In a step toward using human saliva to tell whether those stiff joints, memory lapses, and other telltale signs of aging are normal or red flags for disease, scientists are describing how the protein content of women's saliva change with advancing age.   view more (2009-11-19)

Immune system activated in schizophrenia
Researchers at the Swedish medical university Karolinska Institutet have discovered that patients with recent-onset schizophrenia have higher levels of inflammatory substances in their brains. Their findings offer hope of being able to treat schizophrenia with drugs that affect the immune system.   view more (2009-11-18)

Thoughtful words help couples stay fighting fit
Couples who bring thoughtful words to a fight release lower amounts of stress-related proteins, suggesting that rational communication between partners can ease the impact of marital conflict on the immune system.   view more (2009-11-16)

Faculty of 1000 reviewers examine a study from New Zealand on whether prolonged exposure to the father's semen protects new mothers against pre-eclampsia and having an undersized baby   view more (2009-11-13)

IACC includes vaccine research objective in strategic plan for autism research
Autism Speaks is encouraged by yesterday's decision of the Interagency Autism Coordinating Committee (IACC) to include vaccine research studies in the objectives of the updated Strategic Plan for Autism Research.   view more (2009-11-12)

People with less education could be more susceptible to the flu
People who did not earn a high school diploma could be more likely to get H1N1 and the vaccine might be less effective in them compared to those who earned a diploma, new research shows.   view more (2009-11-11)

Can a plant be altruistic?

Hundreds of genes distinguish patients likely to survive advanced melanoma
Although the chances of surviving advanced melanoma aren't very good with current therapies, some patients can live for years with cancer that has spread beyond the skin to other organs.   view more (2009-11-10)

New Synthetic Molecules Trigger Immune Response to HIV and Prostate Cancer
Researchers at Yale University have developed synthetic molecules capable of enhancing the body's immune response to HIV and HIV-infected cells, as well as to prostate cancer cells. Their findings, published online in the Journal of the American Chemical Society, could lead to novel therapeutic approaches for these diseases.   view more (2009-11-06)

Common Pain Relievers May Dilute Power of Flu Shots
With flu vaccination season in full swing, research from the University of Rochester Medical Center cautions that use of many common pain killers - Advil, Tylenol, aspirin - at the time of injection may blunt the effect of the shot and have a negative effect on the immune system.   view more (2009-11-04)

Daily dose of color may boost immunity this flu season
Hoping to keep the flu at bay? A strong immune system helps. Enjoying the bounty of colorful fruits and vegetables available right now can be an important step toward supporting your family's immune system this cold/flu season.   view more (2009-11-04)
