For a long time, researchers thought that the star-shaped astrocytes (the name comes from the Greek word for star) were simply support cells for the neurons. It turns out that these cells have a number of important jobs, including providing nutrients and signaling molecules to neurons, regulating blood flow, and removing brain chemicals called neurotransmitters from the synapse. The synapse is the point of information transfer between two neurons. At this connection point, neurotransmitters are released from one neuron to affect the electrical properties of the other. Long arms of astrocytes are located next to synapses, where they can keep tabs on the conversations going on between neurons.

A new blood test designed to detect hypermethylation of ten key breast cancer genes accurately detects advanced breast cancer. It has great potential as a method to detect recurrence in asymptomatic patients and monitor treatment response. These are the findings of a study led by researchers in Johns Hopkins Kimmel Cancer Center published on 15th April in the journal Cancer Research.

A new study demonstrates very high plasma levels of a protein called islet amyloid polypeptide (IAPP) in type 1 diabetes patients of recent onset. The study was conducted on serum or plasma samples obtained from a nationwide Swedish prospective cohort study that recruits new-onset Type 1 diabetes children.

A chimeric mouse model called TK-NOG which has a humanized liver would have predicted liver toxicity that developed in humans during the 1993 clinical trial of fialuridine. That is the major finding of a new study from researchers in Stanford University, the Center for the Advancement of Health and Biosciences and the Ely Lilly Department of Drug Disposition, all in California. The study is published on 15th April 2014 in the journal PLoS Medicine.
