Future
Diabetes Treatment May Use Resveratrol To Target The Brain - Science Daily,
10/6/09 - "the brain plays a key role in mediating
resveratrol's anti-diabetic actions, potentially paving the way for future
orally-delivered
diabetes
medications that target the brain ... Resveratrol
activates sirtuins, a class of proteins that are thought to underlie many of the
beneficial effects of calorie restriction" - See
resveratrol products at Amazon.com.
Eating
Licorice In Pregnancy May Affect A Child's IQ And Behavior - Science Daily.
10/6/09 - "Expectant mothers who eat excessive
quantities of licorice during
pregnancy could adversely affect their child's
intelligence and behavior ... They were also more likely to have poor attention
spans and show disruptive behavior such as ADHD (attention deficit hyperactivity
disorder) ... It is thought that a component in licorice called glycyrrhizin may
impair the placenta, allowing stress hormones to cross from the mother to the
baby"
Drivers
Of Convertibles May Be At Risk For Noise-induced Hearing Loss - Science
Daily, 10/6/09 - "Drivers who frequently take to the
road with the top down may be risking serious damage
to their hearing"
How Soy
Reduces Diabetes Risk - Science Daily, 10/6/09 -
"They found that daidzein and equol enhanced
adipocyte differentiation, or the formation of fat cells, through activation of
a key transcription regulator, the same receptor that mediates the
insulin-sensitizing effects of anti-diabetes drugs. Thus, daidzein and equol
daidzein and equol seem to work in a similar manner as anti-diabetic drugs
currently in the market"
Click here of a 10/5/09 news clip (I put it on YouTube) that claims that
metformin may provide the same anti-aging
benefits as calorie restriction (you won't need
to look like a POW). Metformin is another one I take for anti-aging.
In addition to the calorie restriction type benefits, see my
Insulin and Aging page.
Curcumin
May Inhibit Nicotine-induced Activation Of Head And Neck Cancers - Science
Daily, 10/4/09 - "HNSCC
cells were pre-treated with curcumin and then nicotine was introduced. The
results of the studies showed that the curcumin
was able to block the nicotine from activating cancer ... Although nicotine
itself has not been shown to be carcinogenic, it has been shown to encourage the
cancer-forming process" - See

from over-responding when a virus hits. This balance helps prevent T cells,
which ordinarily serve the immune system, from causing harm"
Low-Cost Drugs Prevent Heart Attack, Stroke - WebMD, 10/1/09 -
"Besides being encouraged to take a daily aspirin,
patients were prescribed a medication bundle, typically lovastatin (40
milligrams a day) to lower cholesterol and lisinopril (20 milligrams a day) to
lower blood pressure ... Compared with the no-exposure group, the low-exposure
group (whose members picked up medicines less than half the time) had a 60%
reduction in hospitalizations for heart attack and stroke"
Oxidized
Form Of A Common Vitamin May Bring Relief For Ulcerative Colitis - Science
Daily, 10/1/09 - "Here's another reason why you should
take your vitamins. A new research report appearing in the October 2009 print
issue of the Journal of Leukocyte Biology suggests that retinoic acid, the
oxidized form of vitamin A, could be a
beneficial treatment for people suffering from
ulcerative colitis and other irritable bowel diseases"
Eating
Sweets Every Day In Childhood 'Increases Adult Aggression' - Science Daily,

9/30/09 - "One group was required to drink 65 ml of
Yakult daily, giving a daily probiotic dose of 100 billion bacteria per 100 ml.
The other group was given no product to consume at all ... analysis of the fluid
between the gum and the tooth (gingival crevicular
fluid) showed that the probiotic was
associated with reductions were in elastase activity, and enzyme linked to
inflammation, and matrix metalloproteinase-3 (MMP-3), an enzyme that is
responsible for the degradation of extracellular matrix components and known to
have increased activity during inflammation" - [Abstract]

Pioglitazone Reduces ER Stress in the Liver: Direct Monitoring of in vivo ER
Stress Using ER Stress-activated Indicator Transgenic Mice - Endocr J. 2009
Sep 29 - "8 weeks of
pioglitazone treatment
reduced the accumulation of fat droplets in the liver and attenuated the
development of insulin resistance. In the liver of the ERAI transgenic mice,
ERAI fluorescence activity was clearly reduced as early as after 4 weeks of
pioglitazone treatment, preceding the improvement of insulin resistance. In
addition, after the pioglitazone treatment, serum free fatty acid and
triglyceride levels were decreased, and serum
adiponectin levels were increased. These data indicate that pioglitazone
treatment suppresses ER stress in the liver which may explain, at least in part,
the pharmacological effects of pioglitazone to reduce insulin resistance"
- Note: Pioglitazone is one that I take for anti-aging. See my
Insulin and Aging page. See pioglitazone

has been shown to have antioxidative properties; however, it remains unclear
whether silibinin improves Abeta-induced neurotoxicity ... Silibinin prevented
the memory impairment induced by Abeta(25-35) in the Y-maze and novel object
recognition tests. Repeated treatment with silibinin attenuated the
Abeta(25-35)-induced accumulation of malondialdehyde and depletion of
glutathione in the hippocampus ... Silibinin prevents memory impairment and

Alcohol
consumption as a risk factor for dementia and cognitive decline: meta-analysis
of prospective studies - Am J Geriatr Psychiatry. 2009 Jul;17(7):542-55 -
"Alzheimer disease (AD) ... vascular
dementia (VaD) ... The pooled relative risks (RRs) of AD, VaD, and Any
dementia for light to moderate drinkers compared with nondrinkers were 0.72 (95%
CI = 0.61-0.86), 0.75 (95% CI = 0.57-0.98), and 0.74 (95% CI = 0.61-0.91),
respectively. When the more generally classified "drinkers," were compared with
"nondrinkers," they had a reduced risk of AD (RR = 0.66, 95% CI = 0.47-0.94) and
Any dementia (RR = 0.53, 95% CI = 0.53-0.82) but not cognitive decline. There
were not enough data to examine VaD risk among "drinkers." Those classified as
heavy drinkers did not have an increased risk of Any dementia compared with
nondrinkers, but this may reflect sampling bias. Our results suggest that
alcohol drinkers in late life have reduced risk of dementia. It is unclear
whether this reflects selection effects in cohort studies commencing in late
life, a protective effect of alcohol consumption throughout adulthood, or a
specific benefit of alcohol in late life"

Statins Can Protect Against Alzheimer’s Disease, According To New Study
- Science Daily, 6/22/09 - "They clearly
demonstrated that treatment with a statin called Lovastatin could prevent
the death of nerve cells under these conditions. The statins not only
prevented cells from dying but also prevented the loss of memory capacity
that normally occurs after such cell death. In a previous study Dolga had
showed that these statins stimulate the protective capacity of tumor
necrosis factor, which is a key player in the brain’s immune response"

Soya
isoflavone supplementation enhances spatial working memory in men - Br J
Nutr. 2009 Jun 1:1-7 - "Volunteers were randomised
to take four capsules/d containing soya isoflavones (116 mg isoflavone
equivalents/d: 68 mg daidzein, 12 mg genistein, 36 mg glycitin) or placebo
for 6 weeks, and the alternate treatment during the following 6 weeks.
Assessments of memory (verbal episodic, auditory and working), executive
function (planning, attention, mental flexibility) and visual-spatial
processing were performed at baseline and after each treatment period.
Isoflavone supplementation significantly improved spatial working memory (P
= 0.01), a test in which females consistently perform better than males.
Compared with placebo supplementation, there were 18 % fewer attempts (P =
0.01), 23 % fewer errors (P = 0.02) and 17 % less time (P = 0.03) required
to correctly identify the requisite information. Isoflavones did not affect
auditory and episodic memory (Paired Associate Learning, Rey's Auditory
Verbal Learning Task, Backward Digit Span and Letter-Number Sequencing),
executive function (Trail Making and Initial Letter Fluency Task) or
visual-spatial processing (Mental Rotation Task). Isoflavone supplementation

Is
Vitamin D Deficiency Linked To Alzheimer's Disease And Vascular Dementia?
- Science Daily, 5/26/09 - "Several studies have
correlated tooth loss with development of cognitive impairment and
Alzheimer's disease or vascular dementia. There are two primary ways that
people lose teeth: dental caries and periodontal disease. Both conditions
are linked to low vitamin D levels, with induction of human cathelicidin by
1,25-dihydroxyvitamin D being the mechanism ... There is also laboratory
evidence for the role of vitamin D in neuroprotection and reducing
inflammation, and ample biological evidence to suggest an important role for
vitamin D in brain development and function ... those over the age of 60
years should consider having their serum 25(OH)D tested, looking for a level
of at least 30 ng/mL but preferably over 40 ng/mL, and supplementing with
1000-2000 IU/day of vitamin D3 or increased time in the sun spring, summer,

Role of
Huperzine A in the Treatment of Alzheimer's Disease - Ann Pharmacother.
2009 Feb 24 - "AD is a progressive neurodegenerative
brain disorder for which there is no cure; available therapies only decrease
cognitive decline. Huperzine A, an alkaloid derived from Chinese club moss
(H. serrata), acts as a selective inhibitor of acetylcholinesterase and may
also display neuroprotective properties. Preliminary data suggest that
huperzine A may improve cognition; studies ranging from 8 to 12 weeks have
found improvements in the Mini-Mental State Examination score of 1-5 points
... Although use of huperzine A has shown promising results in patients with
AD, data supporting its use are limited by weak study design" - See

Neuroprotective Effects of (-)-Epigallocatechin-3-gallate on Aging Mice
Induced by D-Galactose - Biol Pharm Bull. 2009 Jan;32(1):55-60 -
"aim of the present study was to investigate the
protective effects of (-)-epigallocatechin-3-gallate (EGCG), the main
polyphenolic constituent of green tea ... Oral administration of EGCG (2
mg/kg or 6 mg/kg) for 4 weeks significantly improved the cognitive deficits
in mice and elevated T-SOD and GSH-Px activities, decreased MDA contents in
the hippocampus, and reduced the cell apoptosis index and expression of
cleaved caspase-3 in the mouse hippocampus. The results suggest that EGCG
has potent neuroprotective effects on aging mice induced by D-gal through
antioxidative and antiapoptotic mechanisms, indicating that EGCG is worthy
of further study in aging" - See

Blood Sugar Linked To Normal Cognitive Aging - Science Daily, 12/30/08 -
"Beyond the obvious conclusion that preventing
late-life disease would benefit the aging hippocampus, our findings suggest
that maintaining blood sugar levels, even in the absence of diabetes, could
help maintain aspects of cognitive health. More specifically, our findings
predict that any intervention that causes a decrease in blood glucose should
increase dentate gyrus function and would therefore be cognitively
beneficial" - [WebMD]

study had two major limitations: “One, it looks exclusively at people almost 80
years old who are far more likely to have Alzheimer’s, while ignoring those in
middle ages, where the risk for developing the disease rises quickly and
prevention could best be analyzed,” ... Two, it excludes completely any
consideration of the strong and established role that family history plays with
Alzheimer’s. You can’t do a study on the weather without looking at wind and
rain.”"

"A group of centenarians maintained significantly
higher than normal
HDL cholesterol levels, and within the group the
parameter was strongly correlated with
cognitive function ... The centenarians'
offspring were also significantly healthier than their spouses: They were
half as likely to have diabetes or heart attacks and had significantly lower
blood pressure. No strokes occurred among the offspring ... The presence of
HDL might explain the health and longevity in these families. The serum
concentration of HDL typically declines with age by a mean of 5 mg/dL every
8 years ... Had the decline followed the normal pattern, the centenarians'
HDL would have been about 20 mg/dL. But the actual mean value in the group

Telmisartan prevented

partially inhibited this improvement of cognitive decline. Another ARB,
losartan, which has less PPAR-gamma agonistic effect, also inhibited
Abeta-injection-induced cognitive decline; however the effect was smaller
than that of telmisartan and was not affected by GW9662. Immunohistochemical
staining for Abeta showed the reduced Abeta deposition in
telmisartan-treated mice. However, this reduction was not observed in mice

Less Cognitive Impairment Seen in Women Taking Drug for Osteoporosis -
Doctor's Guide, 4/7/05 - "The drug,
raloxifene,
modulates the activity of the hormone estrogen ... the 120 mg dose conferred
a 33% lower risk of developing mild cognitive impairment when compared with
the 60 mg dose and with placebo. The 60 mg dose offered no apparent
prevention of cognitive impairment. While researchers also observed a
reduced risk of developing Alzheimer's disease, that reduction was of
borderline statistical significance"

Specific Type of Cognition Improves with Hormone Replacement in
Postmenopausal Women - Doctor's Guide, 6/24/03 -
"The
oestrogen therapy
had no effect on overall verbal recall; however, it reduced perseverative
errors -- the repetition of words already recalled -- by almost half.
Perseveration is an important part of verbal learning, representing either
inability to inhibit a previously stated response or true forgetting that a
response was already given"

Dementia Not Inevitable With Age - WebMD, 2/11/03 -
"In their study, fully one-half of the 111
nonagenarians -- people 90-99 years old -- had no signs of clinically
measurable memory loss, while another 12% had only mild cognitive
impairment. Only about one in three had
dementia ... One of the things that
struck me is that most of the people we studied who lived into their 90s --
whether or not they had dementia -- had at least one parent who lived into
their 80s or 90s ... And while some were obese, the vast majority of the
study participants and those who had no signs of memory loss were thin"

"pravastatin showed no effect at all on cognition in
PROSPER. Similarly, simvastatin exerted no impact upon cognitive decline in
the earlier 20,536-patient randomized double-blind Heart Protection Study
... It might be better to look at the use of
antihypertensives
in the elderly to prevent cognitive decline”
based upon accumulating extremely promising clinical trials data on that
score ... Prior statin trials in middle-aged patients have shown stroke
prevention but not until after 5-6 years of treatment"

improvement in certain aspects of memory storage ... Combined with earlier
studies, our work clearly shows that calcineurin is involved in learning and
memory ... behavioral changes related to learning involve strengthening the
connections between nerve cells rather than changing the way nerve cells are
hard-wired together"
