Unmasking a Viral Invader

June 6, 2014 1:27 pm | News | Comments

Cytomegalovirus, or CMV, is perhaps one of the biggest pathogens you’ve never heard of—big, both proportionately and epidemiologically. If you’re healthy, it’s harmless, but if you have an impaired immune system, the virus can assert itself with a vengeance. Now, researchers have discovered a menu of tactical secrets CMV employs.

Immune System Molecules May Promote Weight Loss

June 6, 2014 1:12 pm | News | Comments

The calorie-burning triggered by cold temperatures can be achieved biochemically– without the chill– raising hopes for a weight-loss strategy focused on the immune system rather than the brain, according to a new study.          

Seemingly Invincible Cancer Stem Cells Reveal a Weakness

June 6, 2014 12:55 pm | News | Comments

Metastatic cancer cells, which can migrate from primary tumors to seed new malignancies, have thus far been resistant to the current arsenal of anticancer drugs. Now, researchers have identified a critical weakness that actually exploits one of these cells’ apparent strengths—their ability to move and invade tissues.

Three Gene Networks Discovered in Autism

June 6, 2014 12:45 pm | News | Comments

A large new analysis of DNA from thousands of patients has uncovered several underlying gene networks with potentially important roles in autism. These networks may offer attractive targets for developing new autism drugs or repurposing existing drugs that act on components of the networks.

Tool Enables Better Delivery of Brain Cancer Treatment

June 5, 2014 2:17 pm | News | Comments

Surgery and radiation for a glioblastoma have only limited effectiveness because the tumor is particularly aggressive, infiltrating brain tissue surrounding the primary tumor. Scientists have developed a technique designed to open the blood-brain barrier at targeted locations just far enough to allow the passage of drug-bearing nanoparticles.

Tangled Path of Alzheimer's-linked Brain Cells Mapped in Mice

June 5, 2014 12:41 pm | News | Comments

By studying laboratory mice, scientists have succeeded in plotting the labyrinthine paths of some of the largest nerve cells in the mammalian brain: cholinergic neurons, the first cells to degenerate in people with Alzheimer’s disease.      

‘Clever’ DNA Help Bacteria Survive

June 5, 2014 12:38 pm | News | Comments

Scientists have discovered that bacteria can reshape their DNA to survive dehydration. The research shows that bacterial DNA can change from the regular double helix to the more compact A-DNA form, when faced with hostile conditions such as dehydration.

Scientists Discover Basis of Allergic Reactions

June 5, 2014 12:27 pm | News | Comments

While it was known that a specific birch pollen protein causes the immune system to overreact, the exact reason why many people are allergic to birch pollen had not yet been fully clarified. Now, scientists at the Vetmeduni Vienna have discovered what makes the protein an allergen.

Weight Loss Not Influenced by Breakfast

June 5, 2014 11:41 am | News | Comments

Nutritionists regularly suggest breakfast be eaten each morning for health benefits, including weight loss. But new research shows that, when comparing regularly consuming with regularly skipping breakfast, weight loss was not influenced.    

Study Documents MERS Spread from Camel to Person

June 4, 2014 5:17 pm | by Mike Stobbe - AP Medical Writer - Associated Press | News | Comments

A new report offers the strongest evidence yet that a mysterious Middle East virus spreads from camels to people. Researchers studied the illness of a 44-year-old camel owner in Saudi Arabia, who died in November of Middle East respiratory syndrome, or MERS.

Saturated Fat May Influence Expression of Obesity Genes

June 4, 2014 2:28 pm | News | Comments

Limiting saturated fat could help people whose genetic make-up increases their chance of being obese, according to a new study. The findings could be useful in identifying people who are predisposed to obesity and could ultimately lead to personalized dietary recommendations.

Test Predicts if Breast Cancer Will Spread

June 4, 2014 2:21 pm | News | Comments

A test that counts the number of locations in tumor specimens where tumor cells may invade blood vessels predicted the risk of distant spread, or metastasis, for the most common type of breast cancer.               

Experimental Drug Targets Skin, Lung Cancers

June 4, 2014 1:55 pm | News | Comments

Researchers are reporting promising treatment milestones for patients with deadly skin and lung cancers who are being treated with an experimental drug called MK-3475.                        

Scientists Successfully Transplant, Grow Stem Cells in Pigs

June 4, 2014 1:46 pm | News | Comments

One of the biggest challenges for medical researchers studying the effectiveness of stem cell therapies is that transplants or grafts of cells are often rejected by the hosts. Now, researchers have shown that a new line of genetically modified pigs will host transplanted cells without the risk of rejection.
