Fishing Games Gone Wrong: Trial-And-Error Behind Important Cause of Female Infertility PDF Print E-mail
Sep 28, 2011 at 09:35 AM
When an egg cell is being formed, the cellular machinery which separates chromosomes is extremely imprecise at fishing them out of the cell's interior, scientists at the European Molecular Biology Laboratory (EMBL) in Heidelberg, Germany, have discovered. The unexpected degree of trial-and-error involved in this process could explain why errors in the number of chromosomes in the egg cell are the leading cause of miscarriages and severe congenital diseases such as trisomies like Down's syndrome, as well as an important cause of female infertility.

Method May Pave The Way For Treatments For MS, CP, Etc.

Myelin protects nerve axons and provides insulation needed for signals to pass along nerves intact. Loss of the coating results in damage to nerves and diminished signal-carrying capacity, which can be expressed outwardly in symptoms such as loss of coordination and cognitive function.

New,Non-Invasive Test For Detection Of Chromosome Abnormalities May Soon Replace The Existing Method PDF Print E-mail
Jul 20, 2011 at 01:20 PM

An alternative way to test a woman's egg for chromosome abnormalities is being developed by scientists. This new technique can enable doctors to avoid the need to manipulate and biopsy the egg itself. The research can also provide significant new information about the critical role played by some genes in the development of chromosome anomalies.

Cancer Stem Cells Recruit Normal Stem Cells To Fuel Ovarian Cancer PDF Print E-mail
Jul 20, 2011 at 01:10 PM
Researchers have found that a type of normal stem cell fuels ovarian cancer by encouraging cancer stem cells to grow. Cancer stem cells are the small number of cells in a tumor that drive its growth and spread. Traditional cancer treatments do not kill these cells, which is why cancer treatments often fail.
