MIT material stops bleeding in seconds

...al different types of tissue - brain, liver, skin, spinal cord and intestine. "In almost every one of the cases, we were able to immediately stop the bleeding," said Ellis-Behnke, the lead author of the study. Earlier this year, the same researchers reported that a similar liquid was able to partially r...

Newly identified biomarker detects and regulates spread of brain tumors

...rvous system (CNS) and is undetectable in cerebral spinal fluid (CSF), unless malignant astrocytomas--the most common form of intracranial tumors--are present in the CNS. The CSF is a liquid that bathes the brain and acts as a reservoir, which can be sampled for analysis of proteins secreted by CNS tumors. ...

Growth factor stimulates rapid extension of key motor neurons in brain

The volunteers will receive advice on managing their pain and either eight sessions of therapeutic ultrasound (TU) or eight sessions of sham TU. They will also be assessed for pain, disability and general health before the trial, immediat...

How fish mend a broken heart

...certain newts or salamanders can regenerate limbs, spinal cord, retina, brain, and heart tissue. While progenitor cell populations have been identified within most mammalian organs, including skin, skeletal muscle, brain, and heart, these cells vary widely in frequency and the ability to regenerate damage...

Scientists produce neurons from human skin

... does not contain neurons, which are hosted in the spinal cord, but contains only their extensions, called "axons." The researchers?challenge was thus to produce neurons from undifferentiated cells rather than multiply neurons from nerve cells. Tests conducted by the researchers demonstrated that stem ce...

The origin of the brain lies in a worm

...es. While vertebrates have a CNS in the shape of a spinal cord running along their backs, insects and annelid worms like the earthworm have a rope-ladder-like chain of nerve cell clusters on their belly side. Other invertebrates on the other hand have their nerve cells distributed diffusely over their body....

Cancer researchers add spice to research against rare neuromuscular disease

...t the amount of abnormal clumps in the neurons and spinal cords of the mice was slashed by half, and that VEGF activity in the neurons went up more than four times in the treated mice compared to untreated mice. The new research is a signal that new avenues for treating conditions like prostate cancer, b...
