Researchers at Okayama University describe in the journal Scientific Reports the role of an extracellular protein, versican, in regulating tumor growth and providing a newly formed network of blood vessels to further nourish the tumor.

 

High levels of versican are located with tumor blood vessels in normal B16F10 mice (WT), while the genetic variant unable to produce versican (Vcanhdf/+) had much fewer blood vessels in the tumor (A). A diagrammatic representation of how the host versican is modified and relocated to promote angiogenesis and tumor growth (B).

A report that Americans are drinking a lot of coffee might be good news in the battle against colon cancer, scientists with the Simmons Cancer Center at UT Southwestern Medical Center say.

A recent industry survey found that coffee consumption is steadily increasing, with 64 percent of adults reporting having had at least one cup of coffee the previous day. Prior studies have found that coffee drinking is associated with a lower risk of getting colon cancer, as well as reduced risk of recurring tumors and death from colon cancer.

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.

UT Southwestern researchers have identified a major mechanism by which obesity causes type 2 diabetes, which is a common complication of being overweight that afflicts more than 30 million Americans and over 400 million people worldwide.

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.

Cleveland Clinic researchers found that implementing a four-step protocol for the most severe type of heart attack not only improved outcomes and reduced mortality in both men and women, but eliminated or reduced the gender disparities in care and outcomes typically seen in this type of event.

The research was presented at the American College of Cardiology's 67th Annual Scientific Session and published in the Journal of the American College of Cardiology.

Results of a study carried out in Brazil showed a strong association between vitamin D deficiency and metabolic syndrome in postmenopausal women. The Metabolic syndrome (MetS), described as a cluster of conditions that heighten the risk of heart disease, stroke and diabetes, is estimated to affect approximately 50% of the female population above the age of 50 in the United States.
