Women
With Breast Cancer Have Low Vitamin D Levels - Science Daily, 10/9/09 -
"Women with breast cancer should be given high doses of
vitamin D because a majority of them are likely to have low levels of vitamin D,
which could contribute to decreased bone mass and greater risk of fractures ...
nearly 70 percent had low levels of vitamin D in their blood ... Symptoms of
Vitamin D deficiency include muscle pain, weak bones/fractures, low energy and
fatigue, lowered immunity, symptoms of depression and mood swings, and sleep
irregularities, many of which are common for women undergoing breast cancer
treatment" - See

'Red Wine' Chemical May One Day Treat Diabetes - WebMD, 10/9/09 -
"Resveratrol, found
in red wine, was found to lower blood sugar levels and improve insulin levels
when injected directly into the brains of mice fed very high-calorie diets in a
study conducted by researchers at the University of Texas Southwestern Medical
Center (UTSW) ... resveratrol does not cross the blood-brain barrier very
efficiently" - See

This rare cancer occurs in less than 1 of every 100,000 Americans ... Though rare, this is the first report of nasopharyngeal cancer being caused by the HPV epidemic. We are in the middle of a tonsil cancer epidemic, seeing many patients with tonsil cancer linked to HPV. It turns out that HPV may also be a new cause of this rare form of cancer that occurs in this hidden location"
Omega-3 may prevent age-related sight loss - Nutra USA, 10/8/09 -
"a meta-analysis published in the June 2008 issue of the
Archives of Ophthalmology found that a high intake of
omega-3 fatty acids and fish may reduce the
risk of AMD by up to 38 per cent ... Over 12
years of study, the researchers found that intakes of omega-3, estimated using a
food-frequency questionnaire, were related to both wet and dry AMD risk ...
Indeed, participants with the highest omega-3 intakes, equivalent to about 0.11
per cent of their total energy intakes, had a 30 per cent lower risk of
developing both types than people with the lowest intakes" - [Abstract]

Medication Effective For Acute Liver Failure In Early Stages Of Disease, Study
Suggests - Science Daily, 10/8/09 - "Researchers
found that 52 percent of acute liver failure
patients in mild to moderate comas survived when treated with
NAC, compared to just 30 percent of those treated with only a placebo. In
patients experiencing more severe coma, treatment with NAC did not result in a
significant difference in survival rates" - See

Scientists Explain Cellular Effects Of Vitamin A Overdose And Deficiency - Science Daily, 10/8/09 - "retinol, the key component of vitamin A, is essential for the metabolic fitness of mitochondria and acts as a nutritional sensor for the creation of energy in cells. When there is too much or too little vitamin A, mitochondria do not function properly, wreaking havoc on our organs ... It goes to the nucleus of our cells and can affect our health for better or worse"
Protective Role For Copper In Alzheimer’s Disease - Science Daily, 10/8/09 -
"Two articles in a forthcoming issue of the Journal of
Alzheimer’s Disease -- by Dr Chris Exley, Reader in Bioinorganic Chemistry in
the Research Institute for the Environment, Physical Sciences and Applied
Mathematics at Keele University, UK, and Dr Zhao-Feng Jiang, of Beijing Union
University, Beijing, China -- have confirmed a potentially protective role for
copper in
Alzheimer’s disease" - See

folate intake from foods and supplements had a
20 per cent decrease in risk of developing hearing
loss" - See

Low
HDL Levels as the Most Common Metabolic Syndrome Risk Factor in Heart Failure
- Int Heart J. 2009 Sep;50(5):571-80 - "The most
prevalent parameters were low HDL-C (69%) and
hypertension (69%) in all participants"
- Note: The best way to raise HDL is with
niacin. The no flush form doesn't work and the slow release may cause
liver damage. People complain about the flush but I've been taking it for
years and the longer you take it the less flush. After a while, there is
no flush at all but be sure to take it with food.
http://www.lipidsonline.org/slides/slide01.cfm?tk=25&dpg=34 shows that with
extended release niacin, HDL peaks out at 2,500 mg.
http://www.lipidsonline.org/slides/slide01.cfm?q=effect+of+niacin&dpg=7
shows immediate release crystalline niacin compared to Niaspan. The non
prescription actually works better. I don't see any point in the
prescription other than that it might have less flushing when you first start
taking it. See

The red wine
polyphenol resveratrol reduces polycyclic aromatic hydrocarbon-induced DNA
damage in MCF-10A cells - Br J Nutr. 2009 Oct 8:1-7 -
"In summary, resveratrol
might protect breast cells against PAH-induced
DNA damage. The underlying mechanism was mediated by phase I enzyme suppression
rather than phase II enzyme induction or oxidative DNA repair" - See

Long-chain polyunsaturated fatty acid intake and 12-y incidence of neovascular
age-related macular degeneration and central geographic atrophy: a prospective
cohort study from the Age-Related Eye Disease Study - Am J Clin Nutr. 2009
Oct 7 - "Participants who reported the highest
omega-3 LCPUFA intake (median: 0.11% of total
energy intake) were 30% less likely than their peers to develop CGA and NV
AMD. The respective odds ratios were 0.65 (95%
CI: 0.45, 0.92; P </= 0.02) and 0.68 (95% CI: 0.49, 0.94; P </= 0.02)" -

enhances p53 acetylation and apoptosis in prostate cancer by inhibiting
MTA1/NuRD complex - Int J Cancer. 2009 Oct 6 - "Our
study identifies MTA1 as a new molecular target of
Res
that may have important clinical applications for
PCa chemoprevention and therapy, and points to the combination of Res with
HDAC inhibitors as an innovative therapeutic strategy for the treatment of PCa"

Only HbA1c was associated with IMT independent of other confounders, while 1h-glucose was not informative ... HbA1c was the most informative glycemic marker with respect to IMT in individuals with NGT" Many Americans Have Prediabetes and Should Be Considered for Metformin Therapy - Diabetes Care. 2009 Oct 6 - "Criteria for consideration of metformin included the presence of both IFG and IGT, with >/=1 additional diabetes risk factor: age <60 years, BMI >/=35 kg/m(2), family history of diabetes, elevated triglycerides, reduced HDL-cholesterol, hypertension, or A1c >6.0% ... To the extent that our findings are representative of the U.S. population, approximately 1 in 12 adults has a combination of prediabetes and risk factors which may justify consideration of metformin treatment for diabetes prevention" - See metformin at IAS.
