In this study, we used a Drosophila model to understand the role of the dec2P384R mutation on animal health and elucidate the mechanisms driving these physiological changes. We found that the expression of the mammalian dec2P384R transgene in fly sleep neurons was sufficient to mimic the short sleep phenotype observed in mammals. Remarkably, dec2P384Rmutants lived significantly longer with improved health despite sleeping less. In particular, dec2P384R mutants were more stress resistant and displayed improved mitochondrial fitness in flight muscles. Differential gene expression analyses went on to reveal several altered tr...

In this study researchers added new insight, showing that high-intensity aerobic exercise, which derives its energy from sugar, can reduce the risk of metastatic cancer by as much as 72%. If so far the general message to the public has been 'be active, be healthy', now researchers can explain how aerobic activity can maximize the prevention of the most aggressive and metastatic types of cancer.
The study combined an animal model in which mice were trained under a strict exercise regimen, with data from healthy human volunteers examined before and after running. The human data, obtained from an epidemiological study ...

This study showed that the leakage of this mitochondrial nucleic material may occur as a result of mitochondrial dysfunction, which may involve genetic mutations in genes encoding mitochondrial proteins or incomplete degradation of mitochondrial dsDNA in the lysosome - which is a 'degradation factory' of the cell. Upon the leakage into the cytoplasm, this undegraded dsDNA is detected by a 'foreign' DNA sensor of the cytoplasm (IFI16) which then triggers the upregulation of mRNAs encoding for inflammatory proteins."
Using a PD zebrafish model (gba mutant), the researchers demonstrated that a combination of PD-like ph...

This study demonstrates the potential of a natural (o-Vanillin) and a synthetic (RG-7112) senolytic compounds to remove senescent IVD cells, decrease SASP factors release, reduce the inflammatory environment and enhance the IVD matrix production. Removal of senescent cells, using senolytics drugs, could lead to improved therapeutic interventions and ultimately decrease pain and a provide a better quality of life of patients living with intervertebral disc degeneration and low back pain.

In conclusion, the study indicates that HBOT may induce significant senolytic effects that include significantly increasing telomere length and clearance of senescent cells in the aging populations.
Data on the Prevalence of Liver Fibrosis in Middle Age
https://www.fightaging.org/archives/2020/11/data-on-the-prevalence-of-liver-fibrosis-in-middle-age/
Fibrosis is a consequence of age-related disarray in tissue maintenance processes, leading to the deposition of scar-like collagen that disrupts tissue structure and function. It is an ultimately fatal issue for which there are only poor treatment options a...

We report that electrical stimulation (ES) stimulation of post-stroke aged rats led to an improved functional recovery of spatial long-term memory (T-maze), but not on the rotating pole or the inclined plane, both tests requiring complex sensorimotor skills. Surprisingly, ES had a detrimental effect on the asymmetric sensorimotor deficit.
Histologically, there was a robust increase in the number of doublecortin-positive cells in the dentate gyrus and SVZ of the infarcted hemisphere and the presence of a considerable number of neurons expressing tubulin beta III in the infarcted area. Among the genes that were unique...

Towards Better Vaccines and a Lower Burden of Infectious Disease in Old People
Over a lifetime, the burden of infectious disease - and particularly persistent infections such as cytomegalovirus - influences the pace of aging via its detrimental impact on immune function in later life. The slow upward trend in life expectancy over the past two centuries is due in no small part to reductions in infectious disease that accompanied improvements in sanitation and then medicine. In addition, in old age, once the immune system declines into ineffectieness, infectious disease becomes a much more serious concern. Infections that a young person defeats with ease become life-threatening. The primary strategy to...

And now for some good news on health
When it comes to health concerns, the COVID-19 pandemic is top of mind for most people right now. And that’s for good reason.
But there is some very good non-COVID health news that may not be getting the attention it deserves. According to the CDC, the rates of six of the top 10 causes of death in this country, which account for about three-quarters of all deaths, have been declining. That’s remarkable. And these improvements are occurring despite an aging population and an obesity epidemic that affects several health conditions.
Six positive health trends
Let’s look at the trends in these conditions and their rank ...

Patients & Vulnerable Populations Pandemically Left in the Dark
By GRACE CORDOVANO PhD, BCPA
To be honest, the United States blew it on the mask front. From a public health, caregiver and patient safety, as well as community transmission standpoint, we are at least 3 months late to game. Anytime a brand new virus that humanity does not have any immunity to makes an appearance, is highly contagious, starts rapidly infecting people as well as the doctors and nurses caring for them, hospitalizing, and killing them in concerning numbers across the globe, we should enable every proactive safety measure at our disposal.
The first confirmed case of COVID-19 in the US was on January 20,...

In this study, by adenovirus-mediated delivery and inducible transgenic mouse models, we demonstrate the proliferation of both HCs and SCs by combined Notch1 and Myc activation in in vitro and in vivo inner ear adult mouse models. These proliferating mature SCs and HCs maintain their respective identities. Moreover, when presented with HC induction signals, reprogrammed adult SCs transdifferentiate into HC-like cells both in vitro and in vivo. Finally, our data suggest that regenerated HC-like cells likely possess functional transduction channels and are able to form connections with adult auditory neurons.

In this study we show, for the first time, significant alterations in cholesterol efflux capacity in adolescents throughout the range of BMI, a relationship between six circulating adipocyte-derived EVs microRNAs targeting ABCA1 and cholesterol efflux capacity, and in vitro alterations of cholesterol efflux in macrophages exposed to visceral adipose tissue adipocyte-derived EVs acquired from human subjects. These results suggest that adipocyte-derived EVs, and their microRNA content, may play a critical role in the early pathological development of ASCVD.

Support for Oxidized Cholesterol as a Primary Cause of Atherosclerosis
https://www.fightaging.org/archives/2018/11/support-for-oxidized-cholesterol-as-a-primary-cause-of-atherosclerosis/
In the paper I'll point out today, the authors provide evidence in support of the concept that it is specifically oxidized cholesterol that is the primary cause of atherosclerosis rather than the condition resulting from too much cholesterol in general. In atheroscl...

This study found that professional chess players had shorter lifespans than those players who had careers outside of chess and argued that this might be due to the mental strain of international chess competition.
In the present study, we focused on survival of International Chess Grandmasters (GMs) which represent players, of whom most are professional, at the highest level. In 2010, the overall life expectancy of GMs at the age of 30 years was 53.6 years, which is significantly greater than the overall weighted mean life expectancy of 45.9 years for the general population. In all three regions examined, mean life...

The suicide rate is increasing. Why is that?
Those of us who work in pediatric intensive care have frequent encounters with the problem of suicide and attempted suicide. It has seemed to me for some years that the numbers are increasing, and this has been shown to be the case. After years of declining, the suicide rate in our country has been increasing, now at about 125 percent of the rate of several decades ago.
This increase accelerated after 2006. Although all age groups showed an increase, the rate among women, particularly adolescent girls, took a notable jump. In 2012 suicide was the second leading cause of death in adolescents aged 12 to 19 years, accounting ...
