Cells: Tumor-activated Protein Promotes Cancer Spread

( Source: MEDICA.de )

Photo: Metastasis [15/05/2013] Researchers at the University of California report that cancers physically alter cells in the lymphatic system – a network of vessels that transports and stores immune cells throughout the body – to promote the spread of disease, a process called metastasis.Cells: Tumor-activated Protein Promotes Cancer Spread - Read more

Nerves: Reversing Paralysis with Restorative Gel

Photo: Nerve cells connect [14/05/2013] Some parts of the body, like the liver, can regenerate themselves after damage. But others, such as our nervous system, are considered either irreparable or slow to recover, leaving thousands with a lifetime of pain, limited mobility, or even paralysis.Nerves: Reversing Paralysis with Restorative Gel - Read more

Cancer Cells: Stability for the Genome

Photo: DNA [10/05/2013] In cancer cells, the genome is often in a chaotic, unstable state. Now, a research group from the Würzburg Biocenter, Germany, found out which enzymes can stabilize DNA.Cancer Cells: Stability for the Genome - Read more

Matrix: Cells Control Neuronal Connections

Photo: Neuron in the net [07/05/2013] Environment moulds behaviour - and not just that of people in society, but also at the microscopic level. This is because, for their function, neurons are dependent on the cell environment, the so-termed extracellular matrix. Matrix: Cells Control Neuronal Connections - Read more

Genetics: The Many Faces of the Bacterial Defense System

( Source: MEDICA.de )

Photo: Bacteria [02/05/2013] Even bacteria have a kind of immune system they use to defend themselves against unwanted intruders – in their case, viruses. Scientists at the Helmholtz Center for Infection Research (HZI) in Braunschweig, Germany, were now able to show that this defense system is much more diverse than previously thought and that it comes in multiple versions.Genetics: The Many Faces of the Bacterial Defense System - Read more

Cells: Conversion from Bad Fat to Good Fat

Photo: Fat cells [29/04/2013] Scientists from Swiss Federal Institute of Technology (ETH) Zurich have shown for the first time that brown and white fat cells in a living organism can be converted from one cell type to the other.Cells: Conversion from Bad Fat to Good Fat - Read more

Leukemia: High Treatment Costs Harming Patients

Photo: Blood clots [29/04/2013] The increasing cost of treatments for chronic myeloid leukemia (CML) in the United States has reached unsustainably high levels and may be leaving many patients under- or untreated because they cannot afford care, according to a study.Leukemia: High Treatment Costs Harming Patients - Read more

Children: Detecting Autism from Brain Activity

Photo: Brain [19/04/2013] Neuroscientists from Case Western Reserve University School of Medicine and the University of Toronto have developed an efficient and reliable method of analyzing brain activity to detect autism in children.Children: Detecting Autism from Brain Activity - Read more

Cell Division: How Alzheimer's Could Occur

( Source: MEDICA.de )

Photo: Spherical structures in cells [12/04/2013] A new hypothesis has been developed by researchers from the Ruhr-Universität Bochum (RUB) on how Alzheimer's disease could occur. They analyzed the interaction of the proteins FE65 and BLM that regulate cell division.Cell Division: How Alzheimer's Could Occur - Read more

Light: Moving Cells Holds Medical Promise

( Source: MEDICA.de )

Photo: Immune cell [09/04/2013] Scientists at Washington University School of Medicine in St. Louis have shown they can coax cells to move toward a beam of light. The feat is a first step toward manipulating cells to control insulin secretion or heart rate using light.Light: Moving Cells Holds Medical Promise - Read more
