Recent Longevity News for the week ending 10/2/19 Fruit flies live longer with combination drug treatment - Science Daily, 9/30/19 - "lithium as a mood stabiliser, trametinib as a cancer treatment and rapamycin as an immune system regulator ... The three drugs in question act on different proteins of this network to slow the ageing process and delay the onset of age-related death ... Each drug individually extended lifespan by an average of 11%, while pairing two drugs extended lifespan by roughly 30%. When the three drugs were combined, the fruit flies lived 48% longer than flies in a control group that were not given the treatment ... Previous studies in fruit flies have achieved lifespan extensions of about 5-20%, so we found it was quite remarkable that this drug combination enabled them to live 48% longer ... Rapamycin has undesirable effects on fat metabolism, which can be similar to insulin resistance in people, but lithium appeared to cancel out this effect when the two drugs were given together" - See lithium supplements at Amazon.com.
Is Melatonin Safe to Take
Every Night? - Time, 10/1/19 - "A 0.5 mg dose may be
all that’s needed for sleep-cycle regulation, and should be taken three to five
hours before bed, he says. For people who want to take
melatonin just before bed, a 5 mg dose is
appropriate. “Some people report headaches or stomach problems at higher doses,
but those side-effects are uncommon,” he says ... Still, there are other
concerns. “Melatonin has an incredible safety record, no doubt about it,” says
Dr. Mark Moyad, the Jenkins/Pomkempner director of preventive and alternative
medicine at the University of Michigan. “But it’s a hormone, and you don’t want
to mess around with hormones until you know what they’re doing.” ... People with
existing medical problems should discuss melatonin with their doctor before
using it" - Err! That last line raised my blood pressure. Do
doctors even have any training is supplements? I had a run-in with some
doctors over supplements. They’ve been putting out the same line my entire life.
It reminds me of my second-grade teacher talking about communism and how their
leaders put of the communist line when even they don’t believe it. Most doctors
and nurses even take supplements. Things like saying the supplements aren’t
tested for impurities when ConsumberLab and CVS test them all the time. Have
they read the news on valsartan and Zantac being recalled for cancer causing
impurities? - See

Fish Oil Supplements May Do Your Heart Good - WebMD, 9/30/19 -
"The most up-to-date review of data from 13 prior
studies found daily omega-3 fish oil supplement
use tied to a significant lowering of risk for heart attack ... Daily use of the
supplement -- typically about 840 milligrams per day -- was also linked to a
lower overall risk of dying from heart disease ... the 13 studies involved data
on more than 120,000 adults, a sample size that is 64% larger than any other yet
conducted ... the researchers pointed out that there was a "dose-response"
relationship in the findings: The more omega-3 fish oil a person took in each
day, the greater their protection against heart disease" - [Science

High-fructose and high-fat diet damages liver mitochondria - Science Daily, 10/1/19 - "high levels of fructose in the diet inhibit the liver's ability to properly metabolize fat. This effect is specific to fructose. Indeed, equally high levels of glucose in the diet actually improve the fat-burning function of the liver. This explains why high dietary fructose has more negative health impacts than glucose does, even though they have the same caloric content ... Fructose makes the liver accumulate fat. It acts almost like adding more fat to the diet. This contrasts the effect of adding more glucose to the diet, which promotes the liver's ability to burn fat, and therefore actually makes for a healthier metabolism ... In the high-fat plus fructose group, these mitochondria are fragmented and they're not able to burn fat as well as the healthy mitochondria. But looking at the high-fat diet plus glucose group, those mitochondria become more normal looking because they are burning fat normally" No need to cut down red and processed meat, study says - Science Daily, 9/30/19 - "In one review of 12 trials with 54,000 people, the researchers did not find statistically significant or an important association between meat consumption and the risk of heart disease, diabetes or cancer ... In three systematic reviews of cohort studies following millions of people, a very small reduction in risk among those who had three fewer servings of red or processed meat a week, but the association was uncertain" - [WebMD] - [NYT] - [NYT2] 7 ways drinking more water can make you healthier - CNET, 9/25/19 - "You'll feel energized ...

Molecule links weight gain to gut bacteria - Science Daily, 9/27/19 -
"Their findings could have far-ranging implications for
obesity in affluent countries and malnutrition in impoverished countries ... In
the study, published this week by Science, Dr. Lora Hooper and her research team
found that the commensal, or good, bacteria that live in the guts of mammals
program the metabolic rhythms that govern the body's absorption of dietary fat
... Most mice on that diet become obese. To our surprise, those that had no
HDAC3 in their intestinal lining were able to eat a high fat, high sugar diet
and stay lean ... disrupting the
interactions between the microbiota and the body's clock could make us more
likely to become obese. These disruptions happen frequently in modern life when
we take antibiotics, work overnight shifts, or travel internationally. But we
think that our findings might eventually lead to new treatments for obesity --
and possibly malnutrition -- by altering the bacteria
in our guts" - See

Common
nutrient supplementation may hold the answers to combating Alzheimer's disease
- Science Daily, 9/27/19 - "when these mice are given
high choline in their diet throughout life, they exhibit improvements in spatial
memory, compared with those receiving a normal choline regimen ...
Choline acts
to protect the brain from Alzheimer's disease in at least two ways, both of
which are explored in the new study. First, choline blocks the production of amyloid-beta plaques. Amyloid-beta plaques are the hallmark pathology observed
in Alzheimer's disease ... Secondly, choline supplementation reduces the
activation of microglia. Over-activation of microglia causes brain inflammation
and can eventually lead to neuronal death, thereby compromising cognitive
function. Choline supplementation reduces the activation of microglia, offering
further protection from the ravages of AD ... it is well understood that
Alzheimer's disease causes harm to the brain long before clinical symptoms are
made evident. And once these symptoms are identified, it is too late -- the
disease has become irreversible. In addition to causing disorientation and
memory loss, the disease causes loss of motor control in those who are afflicted
... This study shows that the simple addition of choline in the diet throughout
life may reduce AD pathology in those most affected by the disease ... The
current established adequate intake level of choline for adult women (>19yrs of
age) is 425mg/day, and 550mg/day for adult men. A converging line of evidence
indicates that even the current recommended daily intake (RDI) may not be
optimal for a proper aging process, especially in women ... The tolerable upper
limit (TUL) of choline unlikely to cause side effects for adult females and
males (>19yrs of age) is 3500mg/day, which is 8.24 times higher than the
425mg/day recommendation for females and 6.36 times higher than the 550mg/day
recommendation for males ... vitamin supplements containing choline, for example
choline bitartrate and choline chloride, are widely available at affordable
costs. The vitamin supplements containing choline are particularly relevant for
those who are on plant-based diets" - See

The prevalence of periodontitis -- a serious gum infection that damages the soft tissue and destroys the bone that supports your teeth -- also increases with age. As many as 64% of older adults in the U.S. have periodontitis ... Periodontitis is associated with a variety of medical conditions including cardiovascular disease and diabetes.

Omega-3s Recommended as
Adjunctive Therapy for Major Depression - Medscape, 9/25/19 -
"The guideline notes that there is a growing body of
evidence demonstrating the efficacy of n-3 PUFAs
as an adjunctive treatment for MDD. The guideline authors also note that
omega-3s are safe and effective for accelerating the effect of antidepressants
at treatment initiation and for augmenting existing antidepressant therapy when
efficacy is inadequate ... With respect to formulation and dosage, the guideline
recommends pure eicosapentaenoic acid (EPA) or a combination of EPA and
docosahexaenoic acid, with net EPA starting from at least 1 g/day up to 2 g/day
for at least 8 weeks as adjunctive treatment. Importantly, the authors note that
the quality of n-3 PUFAs may affect therapeutic activity ... The guideline also
endorses n-3 PUFAs as a potential prophylactic treatment for high-risk
populations, in addition to standard medical care" - See

Vitamin
D and fish oil show promise in prevention of cancer death and heart attacks
- Science Daily, 9/24/19 - "Nearly 26,000 U.S. men and
women participated in the nationwide VITAL clinical trial. After more than five
years of study and treatment, the results show promising signals for certain
outcomes. For example, while Omega-3 fatty acids
(fish oil) showed only a small, but nonsignificant, reduction in the primary
cardiovascular endpoint of major CVD
events, they were associated with significant reductions in heart attacks. The
greatest treatment benefit was seen in people with dietary fish intake below the
cohort median of 1.5 servings per week but not in those whose intake was above
that level. In addition, African-Americans appeared to experience the greatest
risk reductions. The heart health benefits are now confirmed by recent
meta-analyses of omega-3 randomized trials. ... Similarly,
vitamin D supplementation did not reduce major
CVD events or total cancer incidence but was associated with a statistically
significant reduction in total cancer mortality
among those in the trial at least two years. The effect of vitamin D in reducing
cancer death is also confirmed by updated meta-analyses of vitamin D trials to
date." - See

Wet mucus prevents the disinfectant from reaching the virus, which means the virus remained active after 120 seconds of EBD exposure ... By contrast, washing hands under plain water for 30 seconds inactivated the virus, regardless of whether it was initially surrounded by wet or dry mucus"
Low Vitamin D Levels, Shorter Life? - WebMD, 9/20/29 -
"Those with low
vitamin D levels in their blood were nearly three times more likely to die
during the study period than those with adequate levels ... When it came to the
cause of death, vitamin D levels were most clearly linked to deaths from
diabetes complications ... In fact, a recent study, published in the New England
Journal of Medicine, yielded disappointing results: Researchers found that
vitamin D supplements did not help prevent type 2 diabetes in people at high
risk of the disease ... But that may be in part because supplements later in
life might not be enough to prevent a disease ... In general, vitamin D
concentrations of 50 nmol/L or higher are considered to be high enough for
overall health" - See

This should be reflected in the advice provided to the public and in the advocacy undertaken by groups active in bone-health promotion. This finding is of immediate relevance to public health endeavors for osteoporosis prevention and to those counseling patients regarding fracture prevention" Inulin: Is This Commonly Used Fiber Additive Friend or Foe? - Medscape, 9/19/19 - "The amount of inulin that should be consumed depends on individual tolerance and goals. In adults with specific conditions, the following amounts are recommended[19]: For those with diabetes: 10 g/day for 8 weeks ... For weight loss: 10-30 g/day for 6-8 weeks ... To lower high triglycerides: 14 g/day ... To relieve constipation: 12-40 g/day for 4 weeks" - Note: I posted my ice cream recipe several times where I substituted have the sugar with inulin. Weeding Out the Problem: The Impact of Preoperative Cannabinoid Use on Pain in the Perioperative Period - Medscape, 9/19/19 - "Patients who were on preoperative cannabinoids had higher pain numerical rating score (median [25th, 75th percentiles]) at rest (5.0 [3.0, 6.1] vs 3.0 [2.0, 5.5], P = .010) and with movement (8.0 [6.0, 9.0] vs 7.0 [3.5, 8.5], P = .003), and a higher incidence of moderate-to-severe pain at rest (62.3% vs 45.5%, respectively, P = .004; odds ratio, 1.98; 95% CI, 1.25–3.14) and with movement (85.7% vs 75.2% respectively, P = .021; odds ratio, 1.98; 95% CI, 1.10–3.57) in the early postoperative period compared to patients who were not on cannabinoids. There was also a higher incidence of sleep interruption in the early postoperative period for patients who used cannabinoids." Electric tech could help reverse baldness - Science Daily, 9/19/19 - "Because the devices are powered by the movement of the wearer, they don't require a bulky battery pack or complicated electronics. In fact, they're so low-profile that they could be discreetly worn underneath the crown of an everyday baseball cap ... Small devices called nanogenerators passively gather energy from day-to-day movements and then transmit low-frequency pulses of electricity to the skin. That gentle electric stimulation causes dormant follicles to "wake up." ... Because the electric pulses are incredibly gentle and don't penetrate any deeper than the very outermost layers of the scalp, the devices don't seem to cause any unpleasant side effects. That's a marked advantage over other baldness treatments, like the medicine Propecia, which carries risks of sexual dysfunction, depression and anxiety." - Sounds similar to iRestore.

Scutellarin suppresses
patient-derived xenograft tumor growth by directly targeting AKT in esophageal
squamous cell carcinoma - Cancer Prev Res (Phila). 2019 Sep 25 -
"Scutellarin is a flavonoid compound that is found in scutellaria barbata. It has been reported to exhibit anticancer and
anti-inflammation activities ... We found that scutellarin directly binds to the
AKT1/2 proteins and inhibits activities of AKT1/2 in vitro. The AKT protein is
activated in ESCC tissues and knockdown of AKT significantly suppresses growth
of ESCC cells. Scutellarin significantly inhibits anchorage-dependent and
-independent cell growth and induces G2 phase cell cycle arrest in ESCC cells.
The inhibition of cell growth by scutellarin is dependent on the expression of
the AKT protein. Notably, scutellarin strongly suppresses patient-derived
xenograft ESCC tumor growth in an in vivo mouse model. Taken together, our data
suggest that scutellarin is a novel AKT inhibitor that may prevent progression
of ESCC" - See

Protective effects of
vitamin D on neurophysiologic alterations in brain aging: role of brain-derived

"Vitamin D
supplementation significantly mitigated the observed aging-related reduction in
brain BDNF level and activities of AChE and antioxidant enzymes and elevation in
malondialdehyde level and caspase-3 activity compared to control groups. Brain
BDNF level correlated positively with serum 25(OH) D level and brain AChE
activity and negatively with brain malondialdehyde level and caspase-3 activity
in supplemented groups. Conclusion: Restoring vitamin D levels may, therefore,
represent a useful strategy for healthy brain aging. Augmenting brain BDNF seems
to be a key mechanism through which vitamin D counteracts age-related brain

Thus, protecting from β-cells death in patients with DM may be a useful target in alleviating symptoms of hyperglycemia. Traditional plant-based remedies have been used to treat DM for many centuries and may play a role in protecting β-cell from death. An example of these remedies is Gymnema sylvestre (GS) extract ... Om Santal Adivasi (OSA®) maintained cell membrane integrity in MIN6 cells and mouse islets. Om Santal Adivasi significantly protected MIN6 cells and mouse islets from cytokine-induced apoptosis. In the presence of cytokines, OSA® significantly reduced the expression and activity of caspase-3. The antiapoptotic effect of OSA® as shown by microarray analysis is largely mediated by activating pathways involved in cell survival (mainly casein kinase II pathway) and the free radical scavenger system (specifically superoxide dismutase and catalase). This study indicates that the GS isolate OSA® protects against cytokine-induced apoptosis of β-cells by increasing the expression of cell survival pathways and free radical scavenger system" - See Gymnema sylvestre at Amazon.com.
The gut microbiota
influences skeletal muscle mass and function in mice - Sci Transl Med. 2019
Jul 24;11(502) - "We compared the skeletal muscle of
germ-free mice that lacked a gut microbiota to the
skeletal muscle of pathogen-free mice that had a gut microbiota. Compared to
pathogen-free mouse skeletal muscle, germ-free
mouse skeletal muscle showed atrophy, decreased expression of insulin-like
growth factor 1, and reduced transcription of genes associated with skeletal
muscle growth and mitochondrial function. Nuclear magnetic resonance
spectrometry analysis of skeletal muscle, liver, and serum from germ-free mice
revealed multiple changes in the amounts of amino acids, including glycine and
alanine, compared to pathogen-free mice. Germ-free mice also showed reduced
serum choline, the precursor of acetylcholine, the key neurotransmitter that
signals between muscle and nerve at neuromuscular junctions. Reduced expression
of genes encoding Rapsyn and Lrp4, two proteins important for neuromuscular
junction assembly and function, was also observed in skeletal muscle from
germ-free mice compared to pathogen-free mice. Transplanting the gut microbiota
from pathogen-free mice into germ-free mice resulted in an increase in skeletal
muscle mass, a reduction in muscle atrophy markers, improved oxidative metabolic
capacity of the muscle, and elevated expression of the neuromuscular junction
assembly genes Rapsyn and Lrp4 Treating germ-free mice with short-chain fatty
acids (microbial metabolites) partly reversed skeletal muscle impairments"

The
relationship between vitamin D status and depression in a tactical athlete
population - J Int Soc Sports Nutr. 2019 Sep 10;16(1):40 -
"Depression (defined using diagnostic codes) was more
prevalent in individuals who were diagnosed with vitamin D deficiency (20.4%)
than in individuals who were not (4.2%). After adjustment, vitamin D deficient
diagnoses remained significantly associated with depression diagnoses
(OR = 1.22; 95% CI, 1.11–1.33, p < 0.001). Furthermore, vitamin D deficient
diagnoses were strongly associated with geographic latitude ... These results
suggest that service members stationed at installations located at northerly
latitudes may be at increased risk for vitamin D deficiency. Furthermore,
vitamin D deficient service members may be at higher risk for diagnosis of
depression. As a number of military service members avoid reporting symptoms or
seeking treatment, vitamin D status may be a useful screening tool to identify
service members at risk for depression" - [Nutra
