Help the SENS MitoMouse Rejuvenation Research Project Hit Its Crowdfunding Stretch Goals
The latest crowdfunded research project undertaken by the SENS Research Foundation involves using the genetically engineered maximally modifiable mouse lineage in order to demonstrate the ability to copy a version of the ATP8 mitochondrial gene into the cell nucleus, a process known as allotopic expression, and thus prevent mutational damage to this gene from degrading mitochondrial function. This is a modest step on the road towards bringing this class of genetic engineering project to the point of readiness for commercial development, when a biotech startup company could be created to carry it forward.

In this study, AT1-AAs were detected in the sera of patients with peripheral arterial disease (PAD) and the positive rate was 44.44% vs. 17.46% in non-PAD volunteers. In addition, analysis showed that AT1-AAs level was positively correlated with PAD. To reveal the causal relationship between AT1-AAs and vascular aging, an AT1-AAs-positive rat model was established by active immunization. The carotid pulse wave velocity was higher, and the aortic endothelium-dependent vasodilatation was attenuated significantly in the immunized rats. Morphological staining showed thickening of the aortic wall. Histological examination showe...

Improving Medical AI Safety by Addressing Hidden Stratification
Jared Dunnmon Luke Oakden-Rayner By LUKE OAKDEN-RAYNER MD, JARED DUNNMON, PhD Medical AI testing is unsafe, and that isn’t likely to change anytime soon. No regulator is seriously considering implementing “pharmaceutical style” clinical trials for AI prior to marketing approval, and evidence strongly suggests that pre-clinical testing of medical AI systems is not enough to ensure that they are safe to use. As discussed in a previous post, factors ranging from the laboratory effect to automation bias can contribute to substantial disconnects between pre-clinical performance of AI sys...

Increased Insulin Sensitivity is Not Required for Extension of Healthy Life Span in Mice via Calorie Restriction
The biochemistry surrounding insulin and insulin signaling is very well studied in the context of aging. A number of ways to slow aging in laboratory species involve directly manipulating these signaling pathways. Calorie restriction, like a number of other methods of slowing aging, improves insulin sensitivity, and the consensus in the research community has been that some fraction of the benefits to health and longevity that result from a restricted calorie intake are derived from this change to insulin metabolism. Today's open access paper provides evidence to suggest, surprisingly, that this is not in fact the case. It...

Cycles of DNA Damage and Repair as a Cause of Age-Related Epigenetic Drift
Researchers have recently proposed that the normal operation of DNA repair contributes to the epigenetic change that is observed to occur with age. This is an interesting concept, and we'll see how it progresses in the years ahead, particularly as therapies based on alteration of epigenetic markers emerge as an area of active medical research and development. Epigenetic decorations to DNA are a part of the complex regulatory system controlling the amounts and timing of protein production carried out by a cell. Cells react to changing circumstances with changes to epigenetic markers such as DNA methylation. Some of t...

Lipid Metabolism in Aging and Age-Related Disease
Lipids are everywhere in our biochemistry. Where they are present in cell structures and molecular mechanisms that are important to any specific age-related disease, or are among the underlying root causes of aging, it will tend to be the case that differences between species (and possibly individuals) can lead to changes in the pace of aging and disease. For example, lipid composition determines resistance to oxidative damage to cell membranes. A range of evidence supports the membrane pacemaker hypothesis of aging, in that longer-lived species tend to have more resilient cell membranes, based on their lipid composition. ...

The cost, however, is a slow decline into dysfunction and tissue failure.

A Skeptical Review of the Evidence for Metformin
This review paper more or less leans towards my thoughts on metformin as a treatment to slow aging: the animal data is not great, the human data is a single study, the effect size on life span is far too small to care about, and the detrimental side effects are large in comparison to that effect size. The strategy of upregulating stress response mechanisms via drugs such as metformin is a poor strategy for long-lived species, as we clearly don't exhibit the sizable gains in life span that occur in short lived species such as mice under these circumstances. Metformin, in turn, is a low performance example of this strategy, ...

Implantable Nanolasers for Tissue Imaging, Neurotherapy
A variety of imaging techniques and technologies, such as optogenetics, could benefit from devices that can emit visible laser light from inside tissues. Conventional lasers are too large, while nanolasers tend to be inefficient, heating up too much, and typically require damaging ultraviolet light to power them. Now, researchers at Northwestern and Columbia Universities have developed a nanolaser that can be powered by deep-penetrating and safe infrared light while emitting visible light. The device, less than 150 nanometers in width, uses upconversion to capture multiple low-energy (infrared) photons and turn them...

What donor offspring seek when they do DNA testing
I wrote previously about parents who fear that their donor-conceived children might uncover long-held secrets through DNA testing. Many were unsettled by Dani Shapiro’s memoir Inheritance, which told of how a DNA test done for no particular reason dismantled a family story. Now let’s consider reasons why some people who know they were donor-conceived might pursue DNA testing. Why might people who were donor-conceived seek DNA testing? Donor-conceived adults who embark upon DNA testing may, like Shapiro, stumble upon information accidentally. Their experience with DNA testing is not explored in this post, which ...

Data of the dead participant: what ’s the right thing to do?
by Marieke Bak, MSc, MA, PhD(c) When people die nowadays, they no longer leave behind only physical assets. Their estate includes large amounts of personal data that remain in existence after they pass away. Creating a digital will may be a sensible way to posthumously control digital assets like Facebook pages or Google search histories. However, a recent survey found that the vast majority of us never discuss what should happen to our data after death. When it comes to medical data, particularly those collected in the context of research, the situation is similar.… (Source: blog.bioethics.net)

Conversion of Glial Cells into Neurons as an Approach to Regeneration in the Brain
The authors of today's research report on success in use of a gene therapy to convert glial cells into neurons in a living mouse brain, and thereby improve the normally limited recovery that takes place following brain injury, such as that caused by a stroke. A number of research groups are investigating this class of approach to enhance regeneration in the brain, an organ that has little capacity to repair itself. The capacity that does exist is generated by neural stem cells that, arguably, continue to produce new neurons at some pace throughout life. As for all stem cell populations, activity declines with age, however....

Is the DEA Branching Out Into Regulating Medicine?
Jeffrey A. SingerThe Drug Enforcement Administration, having virtually eliminated the diversion of prescription pain relievers into the underground market for nonmedical users, appears to be setting its sights on regulating the medical management of pain, a mission not suited for law enforcement. Acting under the authority of the Substance Use-Disorder Prevention that Promotes Opioid Recovery and Treatment for Patients and Communities Act (SUPPORT Act), the DEA announced a proposal to reduce, once again, the national production quotas for fentanyl, morphine, hydromorphone (Dilaudid), oxycodone, and oxymorphone, ...
