An end to cancer pain?

An end to cancer pain?

A new study led by University of Toronto researcher Dr. David Lam has discovered the trigger behind the most severe forms of cancer pain. Released in top journal Pain this month, the study points to TMPRSS2 as the culprit: a gene that is also responsible for some of the most aggressive forms of androgen-fuelled cancers.

Beyond genes: Are centrioles carriers of biological information?

Beyond genes: Are centrioles carriers of biological information?

Centrioles are barrel-shaped structures inside cells, made up of multiple proteins. They are currently the focus of much research, since mutations in the proteins that make them up can cause a broad range of diseases, including developmental abnormalities, respiratory conditions, male sterility and cancer. Publishing in Cell Research (Nature), EPFL scientists show that the original centrioles of a fertilized egg, which only come from the father, persist across tens of cell divisions in the developing embryo.

Sound may detect earthquakes on Venus

Sound may detect earthquakes on Venus

Detecting an "earthquake" on Venus would seem to be an impossible task. The planet's surface is a hostile zone of crushing pressure and scorching temperatures--about 874 degrees F, hot enough to melt lead--that would destroy any of the normal instruments used to gauge seismic activity. But conditions in Venus' atmosphere are much more hospitable, and it is here that researchers hope to deploy an array of balloons or satellites that could detect Venusian seismic activity--using sound.

Electronic cigarettes gaining in popularity among teens

Teens no longer smoke just cigarettes. They have branched out to using alternative tobacco products such as electronic cigarettes, hookahs and little cigars. In fact, e-cigarette use is rising rapidly among both cigarette smokers and nonsmokers, according to a study to be presented Sunday, April 26 at the Pediatric Academic Societies (PAS) annual meeting in San Diego.

'Excellent clinical outcomes' For lower-grade brain blood vessel malformation surgery

Interventional treatments, especially surgery,provide good functional outcomes and a high cure rate for patients with lower-grade arteriovenous malformations (AVMs) of the brain, findings which contrast with a recent trial reporting better outcomes without surgery or other interventions for AVMs. "On the basis of these data, in appropriately selected patients, we recommend treatment for low-grade brain AVMs," concludes the study by Dr. Laligam N. Sekhar and colleagues of University of Washington, Seattle.

Stem-cell-based therapy promising for treatment of breast cancer metastases in the brain

Researchers have developed an imageable mouse model of brain-metastatic breast cancer and shown the potential of a stem-cell-based therapy to eliminate metastatic cells from the brain and prolong survival.

7 great achievements in child health research

Pediatric research discoveries over the past 40 years have led to prevention and treatment strategies that have saved millions of lives worldwide. Seven of the greatest research achievements will be presented on Sunday, April 26 at the Pediatric Academic Societies annual meeting at the San Diego Convention Center.

Emoticons and Happy Meals of healthy foods may make students eat better

If it works so well for McDonald's that places like California have tried to ban them, why not make Happy Meals for broccoli?

A paper at the Pediatric Academic Societies (PAS) annual meeting in San Diego says that poor food choices in school cafeterias area risk factor for childhood obesity and students will make better choices if healthy foods are labeled with smiley faces and offe small prizes.

Despite warnings, health food stores recommend OTC dietary supplements to minors

Fifteen year olds are not only able to buy over-the-counter dietary supplements from a sampling of health food stores across the country, the staff at those stores actually went so far as to recommend certain products, despite labels reading "for adult use only."

The American Academy of Pediatrics recommends against using body-shaping supplements -- supplements are unregulated by the US Food & Drug Administration -- for males and females under age 18. Despite the adults-only labeling, it is legal for minors to buy these products in 49 states.

An hour of TV per day linked to unhealthy weight in kindergartners

Do overweight kids watch more television, or does television cause weight kids? That has long been the contention for people seeking a magic bullet in obesity: If we just reduce television time, kids won't be fat.
