New technology could help advance blood biomarker capabilities for improved diagnosis, treatment and prognosis of traumatic brain injury (TBI). An estimated 1.7 million Americans suffer a traumatic brain injury each year, and an estimated 5.3 million individuals -- approximately two percent of the U.S. population -- are living with disability as a result of TBI. Traumatic brain injuries can occur from even the slightest bump or blow to the head.

Bioengineers have identified small molecules that can be used to program stem cells to home in on sites of damage, disease and inflammation. The techniques used to find and test these small molecules may represent important tools in advancing cell-based therapy, offering a new strategy for delivering cells to the right locations in the body.

It is possible to use magnetic resonance imaging to 'see' the inflammation in the pancreas that leads to type 1 diabetes, a pilot study has revealed. Autoimmunity and inflammation directed against the pancreas and its insulin-producing beta cells underlie the development of type 1 diabetes, researchers note.

Researchers have designed and developed hybrid gold-silica nanoparticles, which are turning out to be genuine therapeutic “Swiss Army knives”. Tested in mice and on cultured human cells, they make it possible to combine two forms of tumor treatment and three imaging techniques. They notably have a greater drug loading and delivery capacity than carriers currently on the market, which opens interesting perspectives for cancer research.

Between 5 and 8 million children in the United States have nonalcoholic fatty liver disease (NAFLD), yet most cases go undiagnosed. Medical researchers have now developed a new magnetic resonance imaging (MRI)-based technique to help clinicians and researchers better detect and evaluate NAFLD in children.

Building on previously published research, investigators have advanced technology to allow for time-lapse images of protein synthesis with high spatial-temporal resolution in live cells/tissues and map protein degradation in live cells/tissue. They've successfully demonstrated that this technology can be used to image protein synthesis in brain tissues, zebrafish and mice in vivo, making it a useful tool for biomedical researchers studying complex protein metabolism in everything from cell lines to living animals/humans.

Researchers have shown that brain scans can predict which patients with clinical depression are most likely to benefit from a specific kind of talk therapy. The study is the first to use a technique known as resting-state functional brain connectivity MRI to identify differences in brain wiring that predict therapeutic responses to talk therapy.

As an indicator of prostate cancer, the PSA test is regarded in urology as highly controversial since it is not always unequivocal. A team of researchers has now developed a program that compensates the shortfalls of PSA screening with methods from personalized medicine. As a result, prostate cancer screening is able to reach a new level of quality.

Pancreatic cancer affects approximately 46,000 people each year in the United States and ranks fourth among the leading causes of cancer-related deaths. Only about 6 percent of individuals with pancreatic cancer will live five years after their diagnosis. One reason for this high mortality rate is the lack of effective tools to detect pancreatic cancer early enough to allow its surgical removal. Now researchers are now one step closer to devising an approach to detect pancreatic cancer earlier.
