Mitochondrial dysfunction in tissue stem cells can cause aging-associated degeneration

Aging-related tissue degeneration can be caused by mitochondrial dysfunction in tissue stem cells. The research group of Professor Anu Suomalainen Wartiovaara at the University of Helsinki, with their collaborators in Max Planck Institute for Biology of Aging, Karolinska Institutet and University of Wisconsin, reported on the 3rd January in Cell Metabolism their results on mechanisms of aging-associated degeneration.

Poor handling of oranges in squeezing machines stimulates bacterial contamination

Scientists from the University of Valencia in Spain have analysed fresh orange juice squeezed by machines in catering establishments. They have confirmed that 43% of samples exceeded the acceptable enterobacteriaceae levels laid down by legislation. The researchers recommend that oranges are handled correctly, that juicers are washed properly and that the orange juice is served immediately rather than being stored in metal jugs.

Antioxidant can delay onset of all indicators of Alzheimer's

When you cut an apple and leave it out, it turns brown. Squeeze the apple with lemon juice, an antioxidant, and the process slows down. Simply put, that same "browning" process-known as oxidative stress-happens in the brain as Alzheimer's disease sets in. The underlying cause is believed to be improper processing of a protein associated with the creation of free radicals that cause oxidative stress.

Fatty livers burn more fat, not less

When our livers become loaded with fat, it isn't because they are slacking. A new study of human patients in the December Cell Metabolism shows that fatty livers actually burn more fat, not less. All that "hard work" may be at the root of the organ damage that comes with nonalcoholic fatty liver disease (NAFLD), a condition associated with insulin resistance that affects about one in three in the U.S. population.

Biosensors can detect oxidant production in living organism

Arterial calcification and coronary heart disease, neurodegenerative diseases such as Parkinson's and Alzheimer's, cancer and even the aging process itself are suspected to be partially caused or accelerated by oxidative stress. Oxidative stress arises in tissues when there is an excess of what are called reactive oxygen species.
