They show for the 1st time in the intact mouse brain evidence for an exchange of lactate between different brain cells. With this study they were able to confirm a 20-year old hypothesis. In comparison to other organs, the human brain has the highest energy requirements. A hypothesis from the 1990’s postulates, that a well-orchestrated collaboration between astrocytes and neurons, is the basis of brain energy metabolism.

Astrocytes produce lactate, which flows to neurons to cover their high energy needs. Due to a lack of experimental techniques, it remained unclear whether an exchange of lactate existed between astrocytes and neurons...

Adding seaweed to processed foods such as frozen pizzas, hot dogs and dried pasta will reduce cardiovascular diseases, concludes a new scientific article. One suggestion is to replace 5% of the flour in pizza dough with dried and granulated seaweed. Many seaweed species have a variety of health benefits. They contain, among other things, beneficial proteins, antioxidants, minerals, trace elements, dietary fiber and polyunsaturated fatty acids.

Seaweed’s content of potassium salts does not led to high blood pressure – unlike the sodium salts, typically encountered in the processed food...

Detecting Cancer Cells before they form Metastases

To date, it has been difficult to detect cancer cells in the blood at an early stage: about 1 malignant cell is encountered per billion of healthy cells. “Detection of cancer cells in blood in the early stage of a disease is difficult, because concentrations of the cancer cells are extremely small,” Harald Fuchs explains. “We are searching for the needles in the haystack.” The number of extracted tumor cells allows conclusions to be drawn with respect to the success of therapy and the future course of the disease. Genetic analysis of cells allows therapies to be adapted to the type of cancer to be treated.

“With our method, we reach a very high hit rate: More than 85% of the extracted cells really are ...

Heart Failure Improvements with Diet and Exercise

 

Doctors have shown the benefits of a healthy diet and exercise in patients with heart failure. The annual congress of the Mexican Society of Cardiology is being held in Acapulco from 21 to 25 November 2015. Experts from the European Society of Cardiology (ESC) will present a special programme

In Mexico there are 750,000 patients living with heart failure and the problem is growing. It is estimated that 75,000 more patients will get heart failure each year. “Just 25% of men and 38% of women with heart failure in Mexico will be alive after 5 years,” said Dr Arturo Orea...
