It takes as little as one week of high-fat feeding (HFF) in rodents for adipocytes to become enlarged, storing fo...

A new tool for an old problem

Cancer is characterized by somatic mutations that provide a growth and survival advantage. The mutations are a function of chance because of the random nature of mutagenesis. However, the biology in the tumor cells drives the selection of mutations that are advantageous to the cancer. 1 in addition, the tumor environment exerts a selective pressure on the tumor. For example, the hypoxic environ...

A new approach to an old problem.

A patient with progressive visual loss was found to have an optic nerve sheath meningioma. The patient was treated with stereotactic radiotherapy, a computer-guided stereotactic technique that minimizes the risk of radiation-induced optic neuropathy. Six months after treatment, the patient was doing well and showed no signs of radiation-induced optic neuropathy.
