Blood Vessel

Infection with high-risk strains of the human papillomavirus (HPV), which have been linked to cancer, might increase the risk of heart and blood vessel or cardiovascular disease, especially among women with obesity or other cardiovascular risk factors, according to new research in Circulation Research, an American Heart Association journal.

Researchers at Boston University School of Medicine (BUSM) have identified a new potential target protein (c-Cbl) they believe can help further the understanding of colon cancer and ultimately survival of patients with the disease.

They found colon cancer patients with high levels of c-Cbl lived longer than those with low c-Cbl. Even though scientists have studied this protein in other cancers, it has not been explored in colon cancer until now.

Scientists at the Howard Hughes Medical Institute's Janelia Research Campus have developed a microscope which combines two imaging techniques to capture live 3-D images of cells.

The research was recently published in the journal Science and was led by physicist Eric Betzig. Though scientists have used microscopes to image live cells for centuries, the clearest have been achieved using glass slides to isolate cells

Physicians, trainees and even laypeople can now stand right beside an expert radiologist as he performs one of the most difficult medical procedures of its kind - in virtual reality.

Ziv Haskal, MD, of the University of Virginia Health System, has created a dramatic teaching tool using the power of virtual reality. Whether watched on a high-end VR system or an inexpensive cardboard viewer, Haskal's virtual procedure puts the viewer right next to him as he creates a new blood vessel in a patient's liver through a small nick in the patient's neck.

Tumor cells circulating throughout the body in blood vessels have long been feared as harbingers of metastasizing cancer - even though most free-floating cancer cells will not go on to establish a new tumor.

But if these cast-offs could be accurately counted, they could provide an additional way to track treatment or screen for the disease.

A new study, conducted by a team of researchers from the University of California, San Diego, has identified how the environment surrounding a tumor can stimulate metastatic behavior in the individual cancer cells. Researchers found that the tumor cells activate a particular set of genes and begin to form blood vessel-like structures when they are confined in a densely packed environment.
