Pain: a question of balance

( Source: MEDICA.de )

Photo: Woman with strong headaches [03/08/2015] Pain is usually caused by inflammation in the body. Scientists from the University of Würzburg have now demonstrated that one of the responsible substances simultaneously has a pain-relieving function. Their discovery is a promising target for new therapy.Pain: a question of balance - Read more

Scientists create functional liver cells from stem cells

Photo: Stem cells in green and red [31/07/2015] The liver plays a critical role in human metabolism. This organ is responsible for drug breakdown and is therefore the first to be injured due to overdose or misuse. Evaluating this drug-induced liver injury is a critical part of pharmaceutical drug discovery and must be carried out on human liver cells. Regretfully, human liver cells can only be isolated from donated organs.Scientists create functional liver cells from stem cells - Read more

Iron-containing inflammatory cells in Alzheimer's brains

Graphic: Tree with a face looses it's leaves [24/07/2015] Examining post-mortem tissue from the brains of people with Alzheimer's disease, Stanford University School of Medicine investigators identified what appear to be iron-containing microglia -- specialized scavenger cells that sometimes become inflammatory -- in a particular part of the hippocampus, a key brain structure whose integrity is critical to memory formation.Iron-containing inflammatory cells in Alzheimer's brains - Read more

New material forges the way for 'stem cell factories'

Photo: Man holding a vial [23/07/2015] If you experience a major heart attack the damage could cost you around five billion heart cells. Experts at The University of Nottingham have discovered the first fully synthetic substrate with potential to grow billions of stem cells. The research could forge the way for the creation of 'stem cell factories' - the mass production of human embryonic (pluripotent) stem cells.New material forges the way for 'stem cell factories' - Read more

Observing brain network dynamics to diagnose Alzheimer's

Graphic: Different brain scans lined up [17/07/2015] New research provides insights into how the brain organizes itself, and sets the stage for early diagnosis of neurological disorders like Alzheimer's, in which these certain brain networks break down.Observing brain network dynamics to diagnose Alzheimer's - Read more

Geometry of brain's outer surface correlates with genetic heritage

Photo: Image of brain [10/07/2015] Researchers at the University of California, San Diego and the School of Medicine have found that the three-dimensional shape of the cerebral cortex – the wrinkled outer layer of the brain controlling many functions of thinking and sensation – strongly correlates with ancestral background.Geometry of brain's outer surface correlates with genetic heritage - Read more

How intracellular signaling regulates growth factor production

Graphic: Cutting cells [10/07/2015] Now, researchers from German Leibniz Institute for Age Research (FLI) and Harvard University, US, showed that the factor-precursor-producing cells themselves determine if and when cleavage may occur. This is decided by intracellular signaling. Interfering with defined signaling in cells producing cancer growth factors could be developed into a new way of cancer treatment.How intracellular signaling regulates growth factor production - Read more

Disrupting cells' 'powerhouses' can lead to tumor growth

( Source: MEDICA.de )

Photo: Cells [09/07/2015] Cancer cells defy the rules by which normal cells abide. They can divide without cease, invade distant tissues and consume glucose at abnormal rates. Now a study by University of Pennsylvania researchers implicates defects in mitochondria, the energy-production centers of cells, as playing a key role in the transition from normal to cancerous.Disrupting cells' 'powerhouses' can lead to tumor growth - Read more

Heart attack treatment hypothesis 'busted'

( Source: MEDICA.de )

Photo: Man with heart attack [07/07/2015] Researchers have long had reason to hope that blocking the flow of calcium into the mitochondria of heart and brain cells could be one way to prevent damage caused by heart attacks and strokes. But in a study of mice engineered to lack a key calcium channel in their heart cells, Johns Hopkins scientists appear to have cast a shadow of doubt on that theory.Heart attack treatment hypothesis 'busted' - Read more

'Pulse' technology may replenish skin's collagen
