Freiburger Forscher zeigen, wie ein Protein die unkontrollierte Ausbreitung von Abwehrzellen verhindert
Das menschliche Immunsystem besteht aus Millionen von einzelnen Zellen, die täglich im Knochenmark aus Vorläuferzellen produziert werden. Während ihrer Entwicklung expandieren die Immunzellen und differenzieren sich dann zu reifen Lymphozyten – Abwehrzellen, die Fremdstoffe erkennen und beseitigen. (more…)
A study by UA researchers revealed that rats with neuropathic pain that were bathed in green LED showed more tolerance for thermal and tactile stimulus. A clinical trial involving people suffering from fibromyalgia is underway. (more…)
Forscher beobachten Tumorbildung, bei der die auslösenden Signale aus angrenzendem Gewebe kommen
Der gängigen Lehrmeinung nach entsteht Krebs dadurch, dass einzelne Zellen durch Defekte in ihrer Erbsubstanz entarten, dadurch zusätzliche Fehler entstehen und letztlich die betroffenen Zellen beginnen, unkontrolliert zu wachsen. Diese Primärtumoren können streuen und an anderen Stellen im Körper Metastasen, so genannte Sekundärtumoren, bilden. (more…)
ANN ARBOR — Women who have episiotomies after childbirth reported having poorer body image and less satisfying sex lives than women who tear and heal naturally. (more…)
There are recent cases of gonorrhoea, a common sexually-transmitted infection, which are untreatable by all known antibiotics. However, these cases are from developed countries. It could be even worse in developing or third-world countries. (more…)
Even a single, brief stress can induce days of relapse to cocaine-seeking among rats, but a new study shows how the tendency to relapse persists and how to shut it down, suggesting a new pathway for developing addiction treatment medications. (more…)
First let’s get to understand what fracking is:
According to Environmental Protection Agency, hydraulic fracturing, also known as fracking, produces fractures in the rock formation that stimulate the flow of natural gas or oil, increasing the volumes that can be recovered. Wells may be drilled vertically hundreds to thousands of meters below the land surface and may include horizontal or directional sections extending thousands of meters. (more…)
Paper documents self-healing membrane for fuel cell applications
Fuel cells, which offer a cleaner, more efficient alternative to the combustion of gasoline and other fossil fuels, are an important enabling technology for the nation’s energy portfolio. (more…)
