Better way to track emerging cell therapies using MRIs

Better way to track emerging cell therapies using MRIs

Cellular therapeutics — using intact cells to treat and cure disease — is a hugely promising new approach in medicine but it is hindered by the inability of doctors and scientists to effectively track the movements, destination and persistence of these cells in patients without resorting to invasive procedures, like tissue sampling.

Domestic violence likely more frequent for same-sex couples

Domestic violence likely more frequent for same-sex couples

Domestic violence occurs at least as frequently, and likely even more so, between same-sex couples compared to opposite-sex couples, according to a review of literature by Northwestern Medicine® scientists. Previous studies, when analyzed together, indicate that domestic violence affects 25 percent to 75 percent of lesbian, gay and bisexual individuals. However, a lack of representative data and underreporting of abuse paints an incomplete picture of the true landscape, suggesting even higher rates. Continue reading

Mitochondria’s role in neurodegenerative diseases clearer thanks to mouse study

Mitochondria’s role in neurodegenerative diseases clearer thanks to mouse study

A new study by researchers at the University of Utah School of Medicine sheds light on a longstanding question about the role of mitochondria in debilitating and fatal motor neuron diseases and resulted in a new mouse model to study such illnesses. Researchers led by Janet Shaw, Ph.D., professor of biochemistry, found that when healthy, functioning mitochondria was prevented from moving along axons — nerve fibers that conduct electricity away from neurons — mice developed symptoms of neurodegenerative diseases.

VIP: New way to prevent spread of devastating diseases

VIP: New way to prevent spread of devastating diseases

For decades, researchers have tried to develop broadly effective vaccines to prevent the spread of illnesses such as HIV, malaria, and tuberculosis. While limited progress has been made along these lines, there are still no licensed vaccinations available that can protect most people from these devastating diseases. So what are immunologists to do when vaccines just aren’t working Continue reading

New insights on an ancient plague could improve treatments for infections

New insights on an ancient plague could improve treatments for infections

Dangerous new pathogens such as the Ebola virus invoke scary scenarios of deadly epidemics, but even ancient scourges such as the bubonic plague are still providing researchers with new insights on how the body responds to infections. In a study published online Sept Continue reading

Technique to model infections shows why live vaccines may be most effective

Technique to model infections shows why live vaccines may be most effective

Vaccines against Salmonella that use a live, but weakened, form of the bacteria are more effective than those that use only dead fragments because of the particular way in which they stimulate the immune system, according to research from the University of Cambridge published today. The BBSRC-funded researchers used a new technique that they have developed where several populations of bacteria, each of which has been individually tagged with a unique DNA sequence, are administered to the same host (in this case, a mouse) Continue reading

Professional recommendations against routine prostate cancer screening have little effect

Professional recommendations against routine prostate cancer screening have little effect

The effect of guidelines recommending that elderly men should not be routinely screened for prostate cancer “has been minimal at best,” according to a new study led by researchers at Henry Ford Hospital. The study, published as a research letter online in JAMA Internal Medicine , focused on the use of PSA — prostate-specific antigen — to test for prostate cancer. Continue reading

Responsible use of x-rays in dentistry for children

Responsible use of x-rays in dentistry for children

Children need smaller portions — this is true when it comes to eating meals, and when addressing topics such as imaging. Continue reading

Improving medicines for children in Canada

Improving medicines for children in Canada

Due to concerns about their vulnerability, children have historically been neglected in drug research and development, including clinical trials. But the reality is that children need medicines and are taking them. Data shows that each year, about half of Canadian children use at least one prescription drug. Continue reading

Identifying teen alcohol and drug abuse

Identifying teen alcohol and drug abuse

The number of teens who abuse tobacco, alcohol, drugs and other substances hasn’t changed much in the past couple of decades — but for those who are prone to addiction for one reason or another, the menu of substances to choose from is larger than ever. Continue reading
