Stopping the growth of blood vessels in tumors is a key target for glioblastoma therapies, and imaging methods are essential for initial diagnosis and monitoring the effects of treatments. A team of researchers has developed a combined magnetic resonance imaging (MRI) and ultramicroscopy 'toolkit' to study vessel growth in glioma models in more detail than previously possible.

A new way of using MRI scanners to look for evidence of multiple sclerosis in the brain has been successfully tested by researchers. Multiple sclerosis (MS) is notoriously difficult to diagnose as it has many symptoms but not all sufferers experience all of them and the disease can progress at different rates. MRI scans have been used as a diagnostic tool to detect white matter lesions in the brain but these are not always an indicator of the disease.

Sphingosine kinase inhibitors are a new category of drugs that act on specific enzymes involved in sphingolipid metabolism to reduce the formation of a pro-cancer, pro-inflammatory lipid signaling molecule known as sphingosine-1 phosphate (S1P). Preclinical studies showed that a first-in-class sphingosine kinase 2 inhibitor slowed growth of aggressive prostate cancer cells.

A new MRI imaging technique could reduce the need for amputation in patients with critical limb ischemia, according to a new study. The technique uses a new way of mapping blood delivered to the leg muscle immediately after operations on people with severely reduced blood flow to their limbs. Currently surgeons may need to wait days or weeks to see how successful the surgery has been.

The central nervous system is a key contributor to the problem of painful peripheral nerve disease in people with diabetes, emerging evidence suggests. Diabetic peripheral neuropathy (DPN) occurs in about one-half of all patients with diabetes. In addition to progressive and severe pain, patients with DNP have insensitivity to trauma, placing them at risk of foot ulcerations, infections, and amputations.

Brain scans may identify children who are vulnerable to depression, before symptoms appear, new research indicates. In a new study, the researchers found distinctive brain differences in children known to be at high risk because of family history of depression. The finding suggests that this type of scan could be used to identify children whose risk was previously unknown, allowing them to undergo treatment before developing depression.
