Fight Aging!
May 07, 2021
The membrane pacemaker hypothesis suggests that the lipid composition of membranes, and particularly mitochondrial membranes, is an important determinant of species longevity in at least some clades, such as mammals and birds. Membrane composition determines the degree of resistance to lipid oxidation and consequent loss of function for component parts of a cell. Aging is...
Mesenchymal Stem Cell Therapy as a Treatment for Skin Aging
May 07, 2021
The term "mesenchymal stem cell therapy" covers a very broad range of cell sources and cell capabilities. Arguably the category needs to be thrown out and replaced with a more detailed taxonomy. The results of mesenchymal stem cell therapy in one clinic can be wildly different from those in another due to small differences in...
Fight Aging!

A sizable fraction of sarcopenia, the loss of muscle mass and strength with age, is avoidable. Not all of it, of course, at least not without advances in therapies targeting the underlying mechanisms of aging. But it is in part the consequence of a lack of physical activity, with other contributions arising from diet, changes...
Turning a pancreatic cancer cell’s addiction into a death sentence

(University Health Network) Probing the unique biology of human pancreatic cancer cells in a laboratory has yielded unexpected insights of a weakness that can be used against the cells to kill them.
Breaching the blood-brain barrier to deliver precious payloads
May 07, 2021
(Georgia Institute of Technology) RNA-based drugs may change the standard of care for many diseases, making personalized medicine a reality. So far these cost-effective, easy-to-manufacture drugs haven't been very useful in treating brain tumors and other brain disease. But a team of researchers at Georgia Tech and Emory University has shown that a combination of...
Eureka Alert
May 07, 2021
(Medical University of Vienna) Since the tumour cells of neuroblastoma resemble certain cells in the adrenal glands, a joint research group investigated the cellular origin of these cells and sympathetic neurons during the embryonic development of human adrenal glands. They discovered a previously unknown cell type that might potentially be the origin of the tumour...
