Imaging of scar tissue formation

Science Daily (US) - 19/07/2017
Organs respond to injuries with the formation of new fibrous tissue, which can result in scarring. This process called fibrogenesis can now be monitored noninvasively on a molecular level, as scientists report. They have created a new gadolinium-based probe for magnetic resonance imaging that specifically reports the proteins involved in fibrogenesis. The imaging method may provide a quantitative assessment of the formation of the potentially harmful scar tissue.

High-fat ice cream may not necessarily mean tastier ice cream

Science Daily (US) - 19/07/2017
Even though ice cream connoisseurs may insist that ice cream with more fat tastes better, a team of food scientists found that people generally cannot tell the difference between fat levels in ice creams.

Macrophages made to engulf cancer cells in solid tumors

Science Daily (US) - 19/07/2017
Human macrophages have been engineered to ignore the 'don't eat me' signal both healthy and cancerous cells exhibit. Combined with cancer-specific targeting antibodies, these engineered macrophages invaded and engulfed human tumor cells in a mouse model.

Combining CAR T cells with existing immunotherapies may overcome resistance in glioblastomas

Science Daily (US) - 19/07/2017
Genetically modified “hunter” T cells successfully migrated to and penetrated a deadly type of brain tumor known as glioblastoma (GBM) in a clinical trial of the new therapy, but the cells triggered an immunosuppressive tumor microenvironment and faced a complex mutational landscape that will need to be overcome to better treat this aggressive cancer, researchers report.

Skin vaccination with microneedle patch, influenza fusion protein improves efficacy of flu vaccines

Science Daily (US) - 19/07/2017
A boosting skin vaccination with a biodegradable microneedle patch and protein constructed from sequences of influenza virus subtypes could improve the effectiveness of conventional influenza vaccines, according to a study.

Despite lack of efficacy data, surprising consensus in pediatric anti-epilepsy med scripts

Science Daily (US) - 19/07/2017
A new study indicates that US doctors appear to have reached an unexpected consensus about which anti-seizure medicine to prescribe to their pediatric patients.

New way cells turn off genes

Science Daily (US) - 19/07/2017
For some developmental genes one allele must stay silent, otherwise debilitating syndromes and cancers can arise. Scientists have now uncovered a new imprinting mechanism cells use to keep these genes quiet in mice.

Very low rate of early use of prescription smoking cessation medications among older patients after heart attack

Science Daily (US) - 19/07/2017
Only about 7 percent of older adults who smoked used a prescription smoking cessation medication within 90 days after being discharged from a hospital following a heart attack, according to a study.

Some women may benefit from delaying breast reconstruction following mastectomy

Science Daily (US) - 19/07/2017
Some patients with a combination of risk factors, such as being obese and having diabetes or being a smoker, may benefit from delayed rather than immediate breast implant reconstruction after a mastectomy to decrease their risk for serious wound complications, according to a study.

Definitive genomic study reveals alterations driving most medulloblastoma brain tumors

Science Daily (US) - 19/07/2017
An international consortium completed a landmark study of most common pediatric brain tumor, revealing new cancer genes, laying the foundation to expand precision medicine.

Secrets of our cellular 'energy sensor'

Science Daily (US) - 19/07/2017
Scientists have uncovered a new kind of 'energy sensor' in our cells, changing our understanding of how the body monitors glucose levels and switches on the supply of alternative 'fuels.' It is thought the research could have particular implications for diabetes, in which the level of glucose in the blood is abnormally high.

Social interaction affects cancer patients' response to treatment

Science Daily (US) - 19/07/2017
How well cancer patients fared after chemotherapy was affected by their social interaction with other patients during treatment, according to a new study. Cancer patients were a little more likely to survive for five years or more after chemotherapy if they interacted during chemotherapy with other patients who also survived for five years or more.

Vaccine rejection and hesitancy examined: Effect of calls to promote vaccination

Science Daily (US) - 19/07/2017
The center of a public health debate is whether parents should have their children vaccinated. Researchers challenge statements made by influential individuals who oppose the widespread use of vaccines.

Soil filters out some emerging contaminants before reaching groundwater

Science Daily (US) - 19/07/2017
There is considerable uncertainty surrounding emerging contaminants in aquatic ecosystems and groundwater, and a recent study of compounds from pharmaceuticals and personal care products didn't add much clarity. But it did provide insight into the transport of the chemicals, according to researchers.

New animal models for hepatitis C could pave the way for a vaccine

Science Daily (US) - 19/07/2017
In the rats that roam New York City's streets and tunnels, scientists have found a virus that resembles hepatitis C. They have used it to create the first animal model of the human disease, a breakthrough that potentially could yield a much-needed vaccine.

Major communication gaps between doctors, home health care nurses revealed

Science Daily (US) - 19/07/2017
Serious gaps in communication have been found between physicians and home health care agencies responsible for caring for often elderly patients discharged from hospitals. The problem, the study said, can contribute to hospital readmissions.

Human in vitro fertilization could evolve thanks to piglet study

Science Daily (US) - 19/07/2017
It is estimated that parents seeking to have children through in vitro fertilization (IVF) spend between $12,000 and $15,000 each session plus the cost of medications, which could average between $3,000 and $5,000. Now, researchers have made a discovery that could decrease the costs associated with IVF in humans -- and it all started with piglets.

Brains are more plastic than we thought

Science Daily (US) - 19/07/2017
New research has shown just how adaptive the brain can be, knowledge that could one day be applied to recovery from conditions such as stroke.

Innovative nanosensor for disease diagnosis

Science Daily (US) - 19/07/2017
A research group has developed diagnostic sensors using protein-encapsulated nanocatalysts, which can diagnose certain diseases by analyzing human exhaled breath. This technology enables early monitoring of various diseases through pattern recognition of biomarker gases related to diseases in human exhalation.

Is bone strength hereditary?

Science Daily (US) - 19/07/2017
A new study indicates that bone strength may be inherited and that its genetic determinants are to some extent shared with bone mineral density.
