Read the Rest...Metformin, a Review
Metformin is a drug that shows up in discussion here every so often. It is thought to be a calorie restriction mimetic, recapitulating some of the metabolic changes caused by the practice of calorie restriction. Its effects on life span in laboratory animals are up for debate and further accumulation of evidence – the results [...]

In recent years resveratrol has clearly fallen below the dividing line for work that is useful from a longevity perspective – if it could extend life significantly in mice, that would have been demonstrated by now. You might compare with the size of the effects on mouse lifespan for rapamycin to provide an example of [...]

Singularity Hub looks at the tissue engineering of teeth: “For years, researchers have investigated stem cells in an effort to grow teeth made for a person’s own cells. Toward this end, [scientists] have developed methods to control adult stem cell growth toward generating dental tissue and ‘real’ replacement teeth. [The] researchers’ approach is to extract [...]

For some years researchers have been investigating the mechanisms of limb and organ regrowth in lower animals like salamanders, with an eye to finding out how easy or hard it would be to recreate those same capabilities in mammals – such as we humans. Do we retain the core mechanisms, lying dormant in our biochemistry, [...]

An article from the Wellcome Trust: “Researchers have been engineering cartilage in the laboratory for 15 years or more, but as yet the tissues they have created don’t function properly in human joints. [Researchers] are taking a new approach to try to bridge the gap between laboratory-created cartilage and the tissue our bodies make. … [...]

Following on from a recent post on the involution of the thymus in adults, the process by which it ceases to generate immune cells and atrophies, here is a another paper that considers some of the possible paths to interventions that maintain the thymus into old age. Given experiments in mice showing that transplant of [...]

You might recall research published last near on NRG-1 levels in naked mole-rats. Here is an update: “The typical naked mole rat lives 25 to 30 years, during which it shows little decline in activity, bone health, reproductive capacity and cognitive ability. … Naked mole rats have the highest level of a growth factor called [...]

The choroid plexus is, amongst other things, a filter for cerebrospinal fluid – you might think of this role as analogous to that of the kidney as a filter for blood, though the two organs are very different in structure at every level, and the choroid plexus also produces the fluid it filters. Like all [...]

(HealthDay News) – A new method of repairing leaking mitral heart valves appears safe, a small study shows. In the new study, researchers tested a reversible implant called the Percutaneous Transvenous Mitral Annuloplasty (PTMA) system, which is installed via a catheter. In the heart, the mitral valve controls the flow of blood from the left [...]
