New technology directly reprograms skin fibroblasts for a new role
Scientists have discovered a way to repurpose fibroblasts into functional melanocytes, the body's pigment-producing cells. The technique has immediate and important implications for developing new cell-based treatments for skin diseases such as vitiligo, as well as new screening strategies for melanoma.

Microwave imaging of the breast
Although currently available diagnostic screening systems for breast are effective at detecting early signs of tumors, they are far from perfect, subjecting patients to ionizing radiation and sometimes inflicting discomfort on women who are undergoing screening because of the compression of the breast that is required to produce diagnostically useful images. New research suggests a better, cheaper, and safer way to look for the telltale signs of breast cancer may be with microwaves.

Vessel research offers new direction to study how cancer spreads
Researchers have understood very little about how blood and lymphatic vessels form in the mammalian gut -- until now. A new Cornell University study reports for the first time how arteries form to supply the looping embryonic gut with blood, and how these arteries guide development of the gut's lymphatic system.

Combining images and genetic data proves gene loss behind aggressive ovarian cancers
Cancer Research UK scientists have shown that loss of a gene called PTEN triggers some cases of an aggressive form of ovarian cancer, called high-grade serous ovarian cancer.

Effectiveness of drugs to prevent hepatitis among patients receiving chemotherapy
Among patients with lymphoma undergoing a certain type of chemotherapy, receiving the antiviral drug entecavir resulted in a lower incidence of hepatitis B virus (HBV)-related hepatitis and HBV reactivation, compared with the antiviral drug lamivudine, according to a study in the Dec. 17 issue of JAMA.

Real-time radiation monitor can reduce radiation exposure for medical workers
It's a sound that saves. A 'real-time' radiation monitor that alerts by beeping in response to radiation exposure during cardiac-catheterization procedures significantly reduces the amount of exposure that medical workers receive, University of Texas Southwestern Medical Center researchers found.

Single genetic abnormality accelerates, removes the brakes on Ewing sarcoma tumor growth
The genetic abnormality that drives the bone cancer Ewing sarcoma operates through two distinct processes -- both activating genes that stimulate tumor growth and suppressing those that should keep cancer from developing.

New colorectal cancer risk factor identified
Adiponectin, a collagen-like protein secreted by fat cells, derives from the ADIPOQ gene. Variations in this gene may increase risk for type 2 diabetes, cardiovascular disease, and various cancers. A new study that links specific variations in the ADIPOQ gene to either higher or lower colorectal cancer risk is published in Genetic Testing and Molecular Biomarkers.

E-cigarettes may recruit lower risk teens to nicotine use
A new study finds that one-third of Hawaiian adolescents have tried e-cigarettes, half of whom have never used another tobacco product. This is markedly higher rate than in the continental US. This raises the possibility that e-cigarettes are recruiting lower risk adolescents, who otherwise would be less susceptible to tobacco product use.

Potential new tool for cervical cancer detection and diagnosis
A team of researchers from Central South University in China have demonstrated that a technique known as photoacoustic imaging, which is already under investigation for detecting skin or breast cancers and for monitoring therapy, also has the potential to be a new, faster, cheaper and noninvasive method to detect, diagnose and stage cervical cancer with high accuracy. Their work appears in a new paper in the Optical Society journal Biomedical Optics Express.
