Wednesday Bible Study: Moar genocide
Regarding Psalm 60, the meaning ofShushan Eduth is disputed. It means something like " Lilly of Testimony, " which doesn ' t make a lot of sense. It could be the name of a tune, but some authorities say it ' s the name of a city where Jews resided during the Babylonian exile, although that doesn ' t make much sense in context since this supposedly refers to a battle recounted in 1 Samuel 10, and repeated in 1 Chronicles 19. It could just be a metaphor for the content. Joab is one of David ' s generals, and like various passages in the Deuteronomistic History, this describes the massacre of the Moabites.  Psalm 61...

A Mitochondrial View of Muscle Aging
The hundreds of mitochondria present in every cell are primarily responsible for generating adenosine triphosphate, a chemical energy store molecule used to power cell operations. Mitochondria are the descendants of ancient symbiotic bacteria, and carry a small circular genome, the mitochondrial DNA. They replicate as needed, can fuse together and swap component parts, and damaged mitochondria are removed by cell maintenance processes. Mitochondrial function declines with age for a variety of reasons that include damage to mitochondrial DNA and changes in the expression of genes involved in replication, fusion, and quality...

Fight Aging! Newsletter, February 5th 2024
In conclusion, the Immunity and Redox Clocks allow BA quantification in mice and both the ImmunolAge and RedoxAge in mice relate to lifespan. « Back to Top Senolytic CAR T Cell Therapy Improves Health in Aged Mice https://www.fightaging.org/archives/2024/01/senolytic-car-t-cell-therapy-improves-health-in-aged-mice/ To the degree that senescent cells in a tissue exhibit distinctive surface features, one can deploy technologies such as chimeric antigen receptor T cells to selectively destroy them. T cells will destroy whatever cell binds to the chimeric antigen receptor they are equipped w...

DEL-1 Upregulation Promotes Bone Regeneration in Aged Mice
Bone is constantly remodeled throughout life. The extracellular matrix making up bone tissue is continually broken down by osteoclast cells and built up by osteoblast cells. In youth, these activities are balanced. With aging, however, the activity of osteoclast cells progressively outweighs the activity of osteoblast cells. The consequence is an ever greater loss of bone mineral density leading to osteoporosis. This process is also found in the bone loss characteristic of advanced periodontitis. There are many contributing factors leading to the imbalance in bone remodeling, and it isn't all that clear as to which of them...

A Tour of Geroscience, Largely Focused on Unambitious Goals in the Treatment of Aging
Geroscience is a philosophy of development, suggesting that aging can be slowed and we should work towards means to do so. In practice, geroscience is, more or less, the the name given to that part of the research and development community that aims to produce means to alter metabolism to modestly slow aging. It is best represented by the development of supplements and repurposing of very well studied drugs, near all of which produce smaller benefits to long-term heath than regular moderate exercise, and none of which can match the benefits provided by the practice of calorie restriction. It is entirely unambitious. This l...

LEV Foundation on Senolytics as One Part of a Combination Rejuvenation Therapy
The primary focus of the Longevity Escape Velocity (LEV) Foundation is to demonstrate that therapies based on the repair of forms of underlying molecular damage that cause aging can be combined to produce greater rejuvenation. Research of recent years has demonstrated quite comprehensively that the alternative strategy for treating aging, to manipulate metabolism into a state in which aging occurs modestly more slowly, has so far produced therapies that largely cannot be combined. The combination of any two or more metabolic alterations, induced by supplements or other small molecules, that individually modestly slow aging...

The Germline Impacts Life Span
One evolutionary perspective on life is that the individuals making up a species are secondary concerns, mere wrappers for the all-important germline cells. Evolution optimizes for success in propagation of the germline lineage, not the success of the individual. With that in mind, one might expect to find that the germline can influence the body. That influence doesn't have to be a net positive for the individual, as noted here. The individual is disposable, and health only matters insofar as it enhances reproductive fitness in the eternal, ever-shifting arms race that takes place over evolutionary time. Classica...

In this study, we found that DMC reduced the SASP level in senescent cells. Furthermore, senescent cells enter irreversible cell cycle arrest, which involves the activation of p53/p21 and Rb/p16. In this study we found that the expression levels of p21 and p16 were decreased after DMC treatment. The downregulation of p21 may be attributed to the decrease of p53. In this study, we found that the mRNA level of p53 was reduced after DMC treatment. Ferroptosis is an iron-dependent cell death process, which is accompanied by iron accumulation. Our previous study reported an important role of FECH, an enzyme inserts ferro...

Flagellin Immunization Modestly Extends Life Span After Late-Life Administration in Mice
The immune system recognizes flagellin as foreign. Flagellin is the protein found in flagellae, the whip-like structures that bacteria use to move around. Attacking and destroying these bacteria is very much a part of the immune system's portfolio of normal activities. Thus immunization with flagellin provokes the immune system into greater activity and responsiveness in the short term, and it has been tested in humans as a vaccine adjuvant, intended to make the immune system respond more effectively to the vaccine delivered alongside flagellin. Interestingly, flagellin immunization also makes the immune system clear out h...

Right Heart Catheterization in Tetralogy of Fallot
With the availability of high resolution echocardiographic images and Doppler echocardiography, role of cardiac catheterization has come down in tetralogy of Fallot and other congenital heart diseases in general. Important risks for cardiac catheterization in a deeply cyanotic infant are the chance of precipitation of a cyanotic spell and thrombotic strokes due to hemoconcentration. Chance of precipitating a cyanotic spell are more when pulmonary angiography is attempted through the already narrow right ventricular outflow tract. Hemocontration is due to the diuresis following contrast angiography, which can be prevented ...

In conclusion, FMD cycles have high potential to be effective in increasing the toxicity of a range of therapies against ALL and other blood cancers and should be tested in randomized clinical trials, especially in combination with immunotherapy and low toxicity cancer therapies. In summary, we present a new strategy for improving leukemia treatment by combining FMD with chemotherapy to promote the killing of ALL cells in part by an immune-dependent mechanism. Fasting/FMD has been shown to reduce chemotherapy-associated toxicity in pre-clinical and clinical studies and thus represents a safe and potentially effectiv...

Reviewing the Prospects for Dentin Regeneration
The regrowth of teeth - and the components of teeth, such as dental pulp, dentin, and enamel, that do not naturally exhibit sufficient regenerative capacity to address damage - has been a goal for researchers for some years now. Inroads have been made, but the research community is still some years from being able to sufficiently control the regrowth of entire teeth to produce more than technology demonstrations. Meanwhile, perhaps more meaningful advances have been made towards provoking the regeneration of damaged teeth in situ, finding ways to program cells in and around teeth into more regenerative modes of behavior. ...

Amyloid- β Inhibits Synaptic Proteasomal Function in Alzheimer's Disease
Cells contain many proteasomes, one portion of a broad array of repair and quality control mechanisms. The proteasome is a hollow, capped cylindrical structure made of many component proteins. It admits entry only to proteins that have been decorated with the addition of a ubiquitin molecule. Once inside the proteasome's central chamber, the ubiquinated protein is disassembled into short peptides suitable for reuse in the synthesis of other proteins. This ubiquitin-proteasome system is necessary to prevent the buildup of damaged, misfolded, unfolded, or otherwise unwanted proteins. It has been noted that proteasomal...
