Scientists have been searching for the genetic factors that cause schizophrenia unsuccessfully for years. Well now we know that the disorder is actually caused by what happens in the cells around the genes. Hopefully this knowledge will give us our best treatment yet for the disease in the future.
These cells actually prevent the DNA from functioning properly. These bad genes have the potential to cause some truly devastating diseases.
There is hope for Alzheimer’s patients by suppressing a specific molecule that significantly boosts memory. Baylor University researchers discovered that a molecule called PKR serves two crucial functions in the brain of mice.
Alzheimer’s sufferers also experience PKR-releasing stress in the course of their disease. A drug for human use is still a few years out. But if this one pans out it just might be the memory boosting super drug that saves suffering in Alzheimer’s disease.
Breast milk might solve the controversy over stem cells. We all know that stem cell research has been a hot button for ethical and moral debates for a long time. Now scientists have isolated embryonic-like stem cells in human breast milk.
The stem cells develop into any of the three embryonic germ layers that allow the cells to develop into 220 different cell types. This makes it very powerful in regenerative medicine. But before we get all excited the key testing hasn’t been done yet and major complications could exist.
Your walking speed can tell a lot about you, including your life expectancy. It is just as good an indicator as your health history, blood pressure, or smoking habits. The researchers at the University of Pittsburg have done nine studies since 1986 to investigate the walking speed and life expectancy in senior citizens. The results show a clear link between the two. So when you think about it, kick that walk into gear a little faster.
Spider venom can kill you, but it is creating some revolutionary cures. It already is used in curing impotence and now it can help with epilepsy, high blood pressure, and heart failure. It all comes down to the movement of the ions across the membranes of our cells.
These ion channels govern the movement and the T type calcium channels are linked to congestive heart failure, high blood pressure, epilepsy, and chronic pain. As it turns out the venom of the American Funnel Web Spider has toxins that act on these types of channels. So the blocking is different, if we can develop a calcium channel blocker based on this toxin we will have a new way to identify how these channels work. We will have better drugs for treating pain and disease.
So we can all hope they move fast on these breakthroughs.
Until next week…..
