High
levels of vitamin D in older people can reduce heart disease and diabetes -
Science Daily, 2/16/10 - "Researchers looked at 28
studies including 99,745 participants across a variety of ethnic groups
including men and women. The studies revealed a significant association between
high levels of
vitamin D and a decreased risk of developing
cardiovascular disease (33% compared to low levels of vitamin D), type 2
diabetes (55% reduction) and
metabolic syndrome
(51% reduction)" - See

Dietary
formula that maintains youthful function into old age - Science Daily,
2/12/10 - "Using bagel bits soaked in the supplement to
ensure consistent and accurate dosing, the formula maintained youthful levels of
locomotor activity into old age whereas old mice that were not given the
supplement showed a 50 per cent loss in daily movement, a similar dramatic loss
in the activity of the cellular furnaces that make our energy, and declines in
brain signaling chemicals relevant to locomotion. This builds on the team's
findings that the supplement extends longevity, prevents cognitive declines, and
protects mice from radiation ... Ingredients consists of items that were
purchased in local stores selling vitamin and health supplements for people,
including vitamins B1, C, D, E, acetylsalicylic acid, beta carotene, folic acid,
garlic, ginger root, ginkgo biloba, ginseng, green tea extract, magnesium,
melatonin, potassium, cod liver oil, and flax seed oil" - Sounds like

About ten years ago I did a lot of reading on Dr. Judah
Folkman and Angiostatin,
Endostatin & other anti-angiogenesis drugs and started that webpage on it.
What really caught my eye with Dr, Folkman's research was a picture of a mouse
with a tumor the size of it's head that was fully cured by angiostatin.
They had problems duplicating it in humans though. Someone sent these
articles and they seem to be picking up research on it again:

TED 2010: Halting Blood Vessels Key to New Cancer Treatment; Possibly
Obesity - wired.com, 2/10/10 - "What he found
was that nature has laced a large number of foods, beverages and herbs with
naturally occurring inhibitors of angiogenesis ... He and his researchers
built a simulator to test the effect different foods (see list of foods at
right) would have on blood vessels at concentrations that are available
through eating, rather than concentrated, encapsulated forms. The tests
showed that an extract of resveratrol, found in red grapes and red wine,
would inhibit abnormal angiogenesis by 60 percent. Extracts from
strawberries and soybeans had similar benefits ... They also tested four
teas — a Chinese jasmine tea, Japanese sencha, Earl Gray and a blend of the
Chinese jasmine and Japanese sencha teas. The teas varied in their
potencies. The Chinese Jasmine and Japanese sencha teas were each less
potent than the Earl Grey tea. But when they combined the two teas, the
combination was more potent than either one alone or than the Earl Grey tea.
This means there’s food synergy, Li said,
and that foods likely work best in combination to create benefits"

Highlights from TED 2010, Wednesday: "We can eat to starve cancer" -
boingboing.net, 2/10/10 - "Angiogenesis means the
growth of blood vessels. Your body usually knows how to regulate the growth
of blood vessels, but sometimes there are defects in blood growing and
pruning. Too little angiogenesis can lead to things like wounds that won't
heal, heart attack, and other diseases. Too much angiogenesis leads to other
bad things such as blindness, arthritis. It's is a common denominator of
many diseases. It's also the "hallmark of every type of cancer." ... In
autopsies of people who died in car accidents, doctors have found
microscopic cancers in 40% of woman (breast) and 40% of men (prostate).
Something like 70% of older people have microcancers in their thyroid. But
the cancer is harmless -- "cancer without disease." If you block
angiogenesis the cancer can't grow. "It's a tipping point between harmless
cancer and deadly one.""

Dog's tale of survival opens door in cancer research - USA Today,
7/24/02 - "The treatment is a cocktail of so-called
anti-angiogenic drugs, which have been widely researched for more than a
decade and work by starving tumors of their blood supply. Researchers say
the three-drug combination, which Haber mixed into Navy's regular dog food,
targets the
cancer from many
angles ... When researchers heard that Navy was cancer-free after receiving
a cocktail of drugs already approved by the Food and Drug Administration —
Celebrex,
tamoxifen (sold
as Nolvadex) and
doxycycline — the treatment became known
as the Navy Protocol ... Navy's treatment, though experimental, cost $2,000"

In 2008, the Environmental Protection Agency (EPA) suggested that PERC be
classified as a "likely human carcinogen." Moreover, the EPA found that PERC's
most dangerous noncancer toxicity is brain and nervous system damage -- and set
safe exposure levels well below levels that cause such damage"

Lycopene
effects contributing to prostate health - Nutr Cancer. 2009 Nov;61(6):775-83
- "Epidemiological evidence links
lycopene consumption with decreased
prostate cancer risk ... Lycopene modulates
several of the aforementioned pathways, providing a promising rationale for
prostate cancer risk reduction by lycopene: In many experimental setups,
lycopene reduced inflammatory signals, prevented oxidative DNA damage, modulated
the expression or activity of IGF axis members, of Wnt/beta-catenin and androgen
signalling, and enhanced gap junctional communication. Lycopene's influence on
these pathways likely contributes to the observed cell growth inhibition and
apoptosis induction by lycopene. A substantial part of the lycopene effects can
be explained by its antioxidant action, but other mechanisms might also be
involved" - See

rate compared to the lycopene plus RT group
(P = 0.001). Plasma TBARS levels after RT were also significantly higher in the
RT only group compared to lycopene plus RT group (P = 0.001). In conclusion,
lycopene supplementation significantly reduced the weight loss and prevented
oxidative stress in rats treated with abdominopelvic radiation" - See

Synergistic
role of curcumin with current therapeutics in colorectal cancer: minireview
- Nutr Cancer. 2009 Nov;61(6):842-6 - "Despite the use
of surgical resection and aggressive chemotherapy, nearly 50% of patients with
colorectal carcinoma
develop recurrent disease, highlighting the need for improved therapies.
Curcumin (diferuloylmethane), the major active
ingredient of turmeric (curcuma longa) with no discernable toxicity, has been
shown to inhibit the growth of transformed cells and colon carcinogenesis at the
initiation, promotion, and progression stages in carcinogen-induced rodent
models. In a Phase I clinical trial, curcumin has been found to be extremely
well tolerated and effective ... Existing data suggest that curcumin in
combination with chemotherapy is a superior strategy for treatment of
gastrointestinal cancer" - See

Zinc in
cancer prevention - Nutr Cancer. 2009 Nov;61(6):879-87 -
"Zinc not only improves
cell mediated immune functions but also functions as an antioxidant and
anti-inflammatory agent. Oxidative stress and chronic inflammation have been
implicated in development of many cancers. In patients with
head and neck cancer, we have shown
that nearly 65% of these patients were zinc deficient based on their cellular
zinc concentrations. Natural killer (NK) cell activity and IL-2 generation were
also affected adversely ... Zinc status also correlated with number of hospital
admissions and incidences of infections. NF-kappa B is constitutively activated
in many cancer cells, and this results in activation of antiapoptotic genes,
VEGF, cyclin DI, EGFR, MMP-9 and inflammatory cytokines. Zinc inhibits NF-kappa
B via induction of A-20. Thus, zinc supplementation should have beneficial
effects on cancer by decreasing angiogenesis and induction of inflammatory
cytokines while increasing apoptosis in cancer cells. Based on the above, we
recommend further studies and propose that zinc should be utilized in the
management and chemoprevention of cancer" - See

Successful
Treatment of Severe Hypertriglyceridemia with a Formula Diet Rich in Omega-3
Fatty Acids and Medium-Chain Triglycerides - Ann Nutr Metab. 2010 Feb
12;56(3):170-175 - "Patients with highly increased
plasma
triglyceride levels are at risk of
developing serious complications such as pancreatitis, coronary heart disease
and stroke. Therefore it is important to rapidly decrease plasma triglyceride
levels. A sufficient control of triglyceride levels with drugs like fibrates,
statins or nicotinic acid can usually only be attained after a couple of weeks.
Plasma exchange appears to be a fast but expensive method to reduce triglyceride
levels. In this study we describe the use of a new
omega-3 fatty acid and medium-chain
triglyceride-rich formula diet as a therapeutic concept to reduce plasma
triglyceride levels fast and effectively ... Thirty-two patients with severe
hypertriglyceridemia were treated with the especially composed formula diet for
a period of 7 days. Results: Within this period of time, plasma triglycerides
decreased from 1,601 (402-4,555) to 554 (142-2,382) mg/dl (p < 0.05). Total
cholesterol levels were reduced from 417 (211-841) to 287 (165-457) mg/dl (p <
0.001). Fasting glucose and uric acid levels also slightly decreased (-8%;
-12%). The formula diet as a 1-week treatment was well tolerated and accepted by
the patients" - See

Docosahexaenoic Acid Deficiency and Prefrontal Cortex Neuropathology in
Recurrent Affective Disorders - J Nutr. 2010 Feb 10 -
"Increasing evidence suggests that docosahexaenoic acid
[DHA, 22:6(n-3)], the principal (n-3) fatty acid in brain gray matter, has
neurotrophic and neuroprotective properties. Preliminary clinical evidence also
suggests that the perinatal accrual, and the subsequent dietary maintenance of,
cortical DHA is positively associated with cortical gray matter volumes. The
pathophysiology of recurrent affective disorders, including unipolar and bipolar
depression, is associated with (n-3) fatty acid deficiency, DHA deficits,
impaired astrocyte mediated vascular coupling, neuronal shrinkage, and
reductions in gray matter volume in the prefrontal cortex (PFC). Preclinical
studies have also observed neuronal shrinkage and indices of astrocyte pathology
in the DHA-deficient rat brain. Together, this body of evidence supports the
proposition that DHA deficiency increases vulnerability to neuronal atrophy in
the PFC of patients with affective disorders" - See

Telmisartan:
a Different Angiotensin II Receptor Blocker Protecting a Different Population?
- J Int Med Res. 2009;37(6):1662-1679 - "Telmisartan
has a unique profile among ARBs, with a high affinity for the angiotensin II
type 1 receptor, a long duration of receptor binding, a high lipophilicity and a
long plasma half life. This leads to sustained and powerful blood pressure
lowering when compared with the first marketed ARBs, such as losartan and
valsartan. Some pharmacological properties of telmisartan clearly distinguish it
from other members of the ARB class and may contribute to the clinical effects
seen with telmisartan. A class effect for ARBs cannot be assumed. To date,
telmisartan is the only ARB that has been shown to reduce cardiovascular risk in
at-risk cardiovascular patients"

cancer who received supplements of
coenzyme Q(10) and a mixture of other antioxidants (e.g. vitamin C,
selenium, folic acid and beta-carotene) ... Median predicted survival was 12

Improving outcome of
chemotherapy of metastatic breast cancer by docosahexaenoic acid: a phase II
trial - Br J Cancer. 2009 Dec 15;101(12):1978-85 -
"The objective response rate was 44%. With a mean follow-up time of 31 months
(range 2-96 months), the median TTP was 6 months. Median OS was 22 months and
reached 34 months in the sub-population of patients (n = 12) with the highest
plasma DHA incorporation. The most common grade 3 or 4 toxicity was neutropaenia
(80%). CONCLUSION: DHA during chemotherapy was devoid of adverse side effects
and can improve the outcome of chemotherapy when highly incorporated. DHA has a
potential to specifically chemosensitise tumours" - See

Red clover
extract: a source for substances that activate peroxisome proliferator-activated
receptor alpha and ameliorate the cytokine secretion profile of
lipopolysaccharide-stimulated macrophages - Menopause. 2010 Feb 5 -
"In lipopolysaccharide-stimulated macrophages, red
clover extract and its compounds reduced the secretion of proinflammatory
cytokines, interleukin-6 and tumor necrosis factor alpha, increased the
secretion of the anti-inflammatory interleukin-10, and/or reduced the expression
of nuclear factor-kappaB, inducible nitric oxide synthase, and/or cyclooxygenase
2. Tumor necrosis factor alpha production was most efficiently reduced by
biochanin A and genistein. Interleukin-6 levels were most efficiently reduced by
genistein and equol. CONCLUSIONS:: Owing to its PPARalpha activation and
modulation of the secreted cytokine profile, red clover extract is a putative
candidate for preventing atherosclerosis and, thus, cardiovascular disease"

tea that has been oxidized by fermentation) contains between 3 and 10 per
cent. Oolong tea is semi-fermented tea and is somewhere between green and
black tea ... A key difference between black tea and green tea lies in the
types and amounts of flavonoids. Green teas contain more of the simple
flavonoids called catechins. But when black tea is made, the catechins
undergo oxidation resulting in the generation of more complex varieties,
called thearubigins and theaflavins" - [Abstract]

(-)-Epigallocatechin-3-Gallate Reduces Body Weight with Regulation of Multiple
Genes Expression in Adipose Tissue of Diet-Induced Obese Mice - Ann Nutr
Metab. 2009 Apr 22;54(2):151-157 - "Experimental diets
supplemented with EGCG resulted in reduction of body weight and mass of various
adipose tissues in a dose-dependent manner. EGCG diet also considerably lowered
the levels of plasma triglyceride and liver lipid. In the epididymal white
adipose tissue of EGCG diet-fed mice, the mRNA levels of adipogenic genes such
as peroxisome proliferator-activated receptor-gamma (PPAR-gamma), CCAAT
enhancer-binding protein-alpha (C/EBP-alpha), regulatory element-binding
protein-1c (SREBP-1c), adipocyte fatty acid-binding protein (aP2), lipoprotein
lipase (LPL) and fatty acid synthase (FAS) were significantly decreased.
However, the mRNA levels of carnitine palmitoyl transferase-1 (CPT-1) and
uncoupling protein 2 (UCP2), as well as lipolytic genes such as hormone
sensitive lipase (HSL) and adipose triglyceride lipase (ATGL), were
significantly increased ... These results suggest that green tea EGCG
effectively reduces adipose tissue mass and ameliorates plasma lipid profiles in
high-fat diet-induced obese mice. These effects might be at least partially
mediated via regulation of the expression of multiple genes involved in
adipogenesis, lipolysis, beta-oxidation and thermogenesis in white adipose
tissue"

Catechin
prevents endothelial dysfunction in the prediabetic stage of OLETF rats by
reducing vascular NADPH oxidase activity and expression - Atherosclerosis.
2009 Feb 3 - "studies have indicated that regular intake
of green tea reduces the risk of cardiovascular diseases. This study examined
whether catechin prevents endothelial dysfunction and hyperglycemia in the
prediabetic stage of a type 2 diabetic (T2D) rat ... Catechin significantly
reduced blood pressure (OLETF vs. Catechin-OLETF; 138+/-16mmHg vs. 126+/-16mmHg,
p=0.013), fasting sugar (129+/-11mg/dL vs. 118+/-9mg/dL, p=0.02) and the insulin
level (2.13+/-1.29ng/mL vs. 0.53+/-0.27ng/mL, p=0.004). In the aorta of
Catechin-OLETF at 25 weeks, endothelium-dependent relaxations were significantly
improved and NADPH oxidase activity in aortic rings was markedly decreased
compared with those of OLETF. Catechin reduced vascular reactive oxygen species
formation in the aorta and suppressed the expression of p22phox and p47phox

Dietary
Green Tea Extract Lowers Plasma and Hepatic Triglyceride and Decreases the
Expression of Sterol Regulatory Element-Binding Protein-1c mRNA and Its
Responsive Genes in Fructose-Fed Ovariectomized Rats - J Nutr. 2009 Feb 4 -
"Fructose elevated plasma TG and cholesterol compared
with the S group. GT at 0.5 and 1.0% markedly lowered plasma and liver TG.
Fructose increased the expression of SREBP-1c, fatty acid synthase, and
stearoyl-CoA desaturase 1 mRNAs in the liver, whereas GT decreased the
expression of these lipogenic genes. Similarly, fructose increased the abundance
of hepatic 3-hydroxy-3-methyl-glutaryl-CoA reductase mRNA, whereas GT
significantly decreased its expression ... the lipid-lowering effect of GT is
mediated partly by its inhibition of hepatic lipogenesis involving SREBP-1c and
its responsive genes without affecting lipoprotein assembly"

Tea
consumption and risk of breast cancer - Cancer Epidemiol Biomarkers Prev.
2009 Jan;18(1):341-5 - "Tea consumption was not related
to breast cancer risk overall (P for trend = 0.18). However, when stratified by
age, an inverse association was observed among women less than 50 years: those
consuming three or more cups per day had a 37% reduced breast cancer risk when
compared with women reporting no tea consumption (age and study site-adjusted
odds ratios, 0.63; 95% confidence intervals, 0.44-0.89; P = 0.01) with a
significant test for trend (P = 0.01). The inverse association noted among
younger women was consistent for in situ and invasive breast cancer, and for
ductal and lobular breast cancer ... We observed evidence to support a potential
beneficial influence for breast cancer associated with moderate levels of tea
consumption (three or more cups per day) among younger women. Further research
is needed to confirm this association"

"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"

Epigallocatechin-3-gallate inhibits IL-6 synthesis and suppresses transsignaling
by enhancing soluble gp130 production - Proc Natl Acad Sci U S A. 2008 Sep
16 - "Results from in vivo studies using a rat
adjuvant-induced arthritis model showed specific inhibition of IL-6 levels in
the serum and joints of EGCG-treated rats by 28% and 40%, respectively, with
concomitant amelioration of rat adjuvant-induced arthritis. We also observed a
marked decrease in membrane-bound gp130 protein expression in the joint
homogenates of the EGCG-treated group. In contrast, quantitative RT-PCR showed
that the gp130/IL-6Ralpha mRNA ratio increased by approximately 2-fold,
suggesting a possible mechanism of sgp130 activation by EGCG. Gelatin zymography
results showed EGCG inhibits IL-6/soluble IL-6R-induced matrix
metalloproteinase-2 activity in RA synovial fibroblasts and in joint
homogenates, possibly via up-regulation of sgp130 synthesis. The results of
these studies provide previously undescribed evidence of IL-6 synthesis and
transsignaling inhibition by EGCG with a unique mechanism of sgp130
up-regulation, and thus hold promise as a potential therapeutic agent for RA"

The major green tea
polyphenol, (-)-epigallocatechin-3-gallate, inhibits obesity, metabolic

Sep;138(9):1677-83 - "In mice fed a high-fat diet (60%
energy as fat), supplementation with dietary EGCG treatment (3.2 g/kg diet) for
16 wk reduced body weight (BW) gain, percent body fat, and visceral fat weight
(P < 0.05) compared with mice without EGCG treatment ... EGCG treatment
attenuated insulin resistance, plasma cholesterol, and monocyte chemoattractant
protein concentrations in high-fat-fed mice (P < 0.05). EGCG treatment also
decreased liver weight, liver triglycerides, and plasma alanine aminotransferase
concentrations in high-fat-fed mice (P < 0.05). Histological analyses of liver
samples revealed decreased lipid accumulation in hepatocytes in mice treated
with EGCG compared with high-fat diet-fed mice without EGCG treatment. In
another experiment, 3-mo-old high-fat-induced obese mice receiving short-term
EGCG treatment (3.2 g/kg diet, 4 wk) had decreased mesenteric fat weight and
blood glucose compared with high-fat-fed control mice (P < 0.05). Our results
indicate that long-term EGCG treatment attenuated the development of obesity,
symptoms associated with the metabolic syndrome, and fatty liver. Short-term
EGCG treatment appeared to reverse preexisting high-fat-induced metabolic
pathologies in obese mice. These effects may be mediated by decreased lipid
absorption, decreased inflammation, and other mechanisms"

"Hepatocyte growth factor (HGF) has recently attracted a
considerable amount of attention as a stromal-derived mediator in tumor-stromal
interactions, particularly because of its close involvement in cancer invasion
and metastasis, and (-)-epigallocatechin-3-gallate (EGCG) can modulate the cell
signaling associated with angiogenesis, metastasis, and migration of cancer
cells ... EGCG at physiologically relevant concentration (1muM) suppressed
HGF-induced tumor motility and MMP-9 and uPA activities, and the suppression of
Akt and Erk pathway by EGCG was one of the downstream mechanisms to facilitate
EGCG-induced anti-invasion effects. These results suggest that EGCG may serve as
a therapeutic agent to inhibit HGF-induced invasion in hypopharyngeal carcinoma
patients" - I took six capsules per day of green tea extract when I had
