Recent Longevity News for the week ending 3/11/15: Note: I'm still not getting any significant abstracts in my RSS feeds. This has happened several times in the past but not for this long. Then when they start again I get thousands per day for several weeks. In the meantime I've gone to every two weeks on the newsletter.
New
class of drugs dramatically increases healthy lifespan, mouse study suggests
- Science Daily, 3/9/15 - "like cancer cells, senescent
cells have increased expression of "pro-survival networks" that help them resist
apoptosis or programmed cell death. This finding provided key criteria to search
for potential drug candidates ... Using these criteria, the team homed in on two
available compounds -- the cancer drug dasatinib (sold under the trade name
Sprycel®) and quercetin, a natural compound sold as a supplement that acts as an
antihistamine and anti-inflammatory ... The two compounds had different strong
points. Dasatinib eliminated senescent human fat cell progenitors, while
quercetin was more effective against senescent human endothelial cells and mouse
bone marrow stem cells. A combination of the two was most effective overall ...
In animal models, the compounds improved cardiovascular function and exercise
endurance, reduced osteoporosis and frailty, and extended healthspan" -

quercetin at Amazon.com Letrozole is a promising new treatment of male infertility - Science Daily, 3/7/14 - "Some recently published studies have suggested that in men with obesity-related low testosterone, a low dose of letrozole can normalize testosterone levels ... Doctors think obesity can cause infertility in men because excess fat results in too much estrogen. The body's aromatase enzyme, which is more prevalent in fat, converts androgens (male hormones, such as testosterone) into estrogen. Letrozole inhibits this action of aromatase ... The men received a 2.5-milligram letrozole pill every week" - Note: I've been taking a quarter tablet every other day for years but it's becoming harder and harder to find it without a prescription even among overseas pharmacies. Click here for one place but I've been using the Fempro brand.
Onion
extract may improve high blood sugar and cholesterol - Science Daily, 3/6/15
- "Two doses of onion extract, 400 and 600 mg/kg/day, strongly reduced fasting
blood sugar levels in diabetic rats by 50 percent and 35 percent, respectively,
compared with "baseline" levels at the start of the study before the rodents
received onion extract" - Note: That's a huge amount. 70 kilograms
is about 150 pounds. So 70 * 600 = 42,000. In any case, see onion extract at Amazon.com
Gut
microbial mix relates to stages of blood sugar control - Science Daily,
3/5/15 - "men whose blood sugar control stayed normal
over the year had more gut bacteria that are
considered beneficial for metabolic health, whereas those who stayed prediabetic
had fewer beneficial bacteria and more harmful bacteria ... she said it is
possible that changing one's gut bacteria could prevent diabetes" - See

Oxytocin also reportedly increased the use of body fat as a fuel for energy. There were no serious side effects and no difference in side effects between oxytocin and placebo ... Because oxytocin has sex-specific effects, it needs to be studied in women" - See Oxy Pro (Oxytocin) Nasal Spray at International Anti-aging Systems.
Omega-3 Fatty Acids May Stem Further Damage After Heart Attack - WebMD,
3/4/15 - "374 heart attack survivors who received
standard treatment and took either a 4-gram prescription-only dose of
omega-3 fatty acids each day or a placebo ...
patients taking the omega-3 capsules had lower levels of inflammation and were
39 percent less likely to show deterioration of heart function. There was also
less thickening or scarring of the areas of the heart that were not directly
damaged during the heart attack" - See
fish oil supplements at Amazon.com Oxytocin may enhance social function in psychiatric disorders - Science Daily, 3/4/15 - "a simple injection of the melanocortin drug quickly induced a pair bond in male and female prairie voles without mating, and that bond lasted long after the drug wore away. The researchers also showed the same drug activated oxytocin cells so the cells released oxytocin directly into the brain's reward centers responsible for generating bonds ... Young believes this new found ability to induce an enduring bond in voles means the drug can also enhance attention to and learning from social information in people who have social disorders ... Imagine a drug that could induce the social attention and motivation a mother feels when nursing her infant or the bond between new lovers. This is exactly what we have shown in our latest oxytocin-related research and the chemical's viability to be a therapeutic target for enhancing social function in psychiatric disorders, including autism spectrum disorders and schizophrenia" - See Oxy Pro (Oxytocin) Nasal Spray at International Anti-aging Systems. Love Coffee? Your Heart May, Too - WebMD, 3/3/15 - "drinking three to five cups a day was associated with less calcium build-up in the arteries ... Coffee contains more than 1,000 chemicals, including antioxidants that may be contributing to the health benefits" Marijuana: The allergen you never knew existed - Science Daily, 3/3/15 - "Included in the article is information on case reports regarding episodes of allergic reactions, hypersensitivity and even anaphylaxis (a severe allergic reaction) to cannabis in its various forms. Among other things, cannabis pollen or cannabis smoke exposure has resulted in symptoms of allergic rhinitis (hay fever) conjunctivitis and asthma. Allergic asthma triggered by seasonal and occupational exposure to cannabis has also been reported" - Note: It seems like every week another negative study comes out on marijuana.
Lycopene
may ward off kidney cancer in older women - Science Daily, 3/2/15 -
"after analyzing data from 96,196 women nationwide and
in Detroit who enrolled in the Women's Health Initiative from 1993 to 1998 and
were followed through July 2013 ... Compared with women who reported a lower
intake of lycopene, those who ingested more
had a 39 percent lower risk. No other micronutrient was significantly associated
with the same risk" - See
Jarrow Lyco-Sorb (contains Lyco-O-Mato) at Amazon.com Licorice manufacturers encouraged to state daily limit of consumption - Science Daily, 3/2/15 - "The boy also complained of a bad headache and had high blood pressure ... he had been eating at least 20 licorice sweets each day for the past four months. This resulted in the consumption of 2.88 mg/kg of glycyrrhizic acid (one of the active ingredients of licorice), well above the World Health Organization's recommended maximum of 2 mg/kg"

Female Pattern Hair Loss - Medscape, 2/26/15 - "Recent Phase III clinical
trials demonstrated the efficacy of once daily 5% minoxidil foam for treatment
of FPHL, where a significant change from baseline in the target area hair count
was observed compared to placebo" - See Rogaine at Amazon.com
Plant
chemicals may prevent liver damage caused by fat accumulated during menopause
- Science Daily, 2/25/15 - "The plant compounds used by
the UGA researchers--resveratrol, found in grapes; genistein, found in soybeans;
and quercetin, found in apple peels and onions--have all been shown in previous
studies to be fat-busters, causing fat cells to burst and release their contents
... it's nearly impossible to get enough of any of these compounds through food
or supplements to gain any benefit. However, she said, together they have a
synergistic effect that "cuts the doses you need." ... While the treatment did
not cause the animals ingesting the compounds to lose weight overall, the
researchers saw that visceral fat layers were decreased" - Note: Visceral
fat (abdominal fat) is what most primarily want to reduce. - See
ReserveAge Resveratrol Vegetarian Capsules, 500 Mg, 60-Count
at Amazon.com Experts criticize 'inaccurate' view that B Vitamins have no role in Alzheimer's disease prevention - Science Daily, 2/25/15 - "the analysis of previous clinical trial data published last year cast no doubt whatsoever on the potential of folic acid and vitamin B-12 to prevent dementia, and that the lead author's comments were 'unjustified and misleading' ... taking B vitamins lowers blood levels of a molecule (homocysteine), which in high concentrations acts as a potent risk factor for dementia"
Omega-3
fatty acids, vitamin D may control brain serotonin, affecting behavior and
psychiatric disorders - Science Daily, 2/25/15 - "Serotonin
affects a wide-range of cognitive functions and behaviors including mood,
decision-making, social behavior, impulsive behavior, and even plays a role in
social decision-making by keeping in check aggressive social responses or
impulsive behavior ... Many clinical disorders, such as autism spectrum disorder
(ASD), attention deficit hyperactivity disorder (ADHD), bipolar disorder,
schizophrenia, and depression share as a
unifying attribute low brain serotonin ... This publication suggests that
optimizing intakes of vitamin D,
EPA, and DHA would
optimize brain serotonin concentrations and function, possibly preventing and
ameliorating some of the symptoms associated with these disorders without side
effects" - See

Effects of α-lipoic acid
and eicosapentaenoic acid in overweight and obese women during weight loss -
Obesity (Silver Spring). 2015 Feb;23(2):313-21 - "This is a short-term
double-blind placebo-controlled study with parallel design that lasted 10 weeks.
Of the randomized participants, 97 women received the allocated treatment
[Control, EPA (1.3 g/d),
α-lipoic acid (0.3 g/d), and EPA + α-lipoic acid (1.3
g/d + 0.3 g/d)], and 77 volunteers completed the study. All groups followed an
energy-restricted diet of 30% less than total energy expenditure ...
Body weight
loss was significantly higher (P < 0.05) in those groups supplemented with
α-lipoic acid. EPA supplementation significantly attenuated (P < 0.001) the
decrease in leptin levels that occurs during weight loss" - [Nutra
USA] - Note: The difference in weight loss was 1.3 kg (2.9 pounds)
over ten weeks. See
