Multiple sclerosis: A riddle of the blood-brain barrier solved

( Source: MEDICA.de )

Photo: Loop with a script Multiple Sclerosis [10/04/2015] The creation and progression of multiple sclerosis present scientists with many riddles. Now researchers from the universities of Würzburg and Amsterdam have succeeded in resolving an apparent contradiction in the findings to date. Their work will contribute to a better understanding of the impact of treatments at the so-called blood-brain barrier.Multiple sclerosis: A riddle of the blood-brain barrier solved - Read more

Low-frequency magnetic fields and development of Alzheimer's disease

Photo: Microscope image [09/04/2015] Low-frequency alternating magnetic fields such as those generated by overhead power lines are considered a potential health risk because epidemiological studies indicate that they may aggravate, among other things, neurodegenerative disorders. However, a recent study has produced no evidence that these fields can cause exacerbation or accelerated disease development in relevant mouse models.Low-frequency magnetic fields and development of Alzheimer's disease - Read more

Photo: Measuring tape and pills [30/03/2015] Medication used to treat patients with type II diabetes activates sensors on brain cells that increase hunger, causing people taking this drug to gain more body fat, according to researchers at Georgia State University, Oregon Health and Science University, Georgia Regents University and Charlie Norwood Veterans Administration Medical Center.Why drug for type II diabetes makes people fat - Read more

Neurons: Regeneration in a hostile environment

Photo: Cross section of rat spinal cord [16/03/2015] Damage to the spinal cord rarely heals because the injured nerve cells fail to regenerate. The regrowth of their long nerve fibers is hindered by scar tissue and molecular processes inside the nerves. An international team of researchers now reports that help might be on the way from an unexpected quarter.Neurons: Regeneration in a hostile environment - Read more

Graphic: Two hands protecting a brain icon [20/02/2015] Researchers have long sought treatments that can slow the progression of Parkinson's disease. Current treatments have for decades been only symptomatic in nature, supplying the neurotransmitter dopamine, which the dying nerve cells can no longer produce.Parkinson’s: Growth factor for possible regenerative effects - Read more
