Recent Longevity News for the seven days ending 5/6/09. You should consult your doctor if you are taking any medications. Statin Drugs May Protect Against Cancer And Also Result in Fewer Gallbladder Removals - Science Daily, 5/5/09 - "The research team found a significant inverse association between having statin prescriptions filled and the risk of developing HCC. There was a trend toward stronger risk reduction with longer and more frequent statin prescriptions"
Tea For
The Treatment Of Type-2 Diabetes - Science Daily, 5/5/09 -
"The research subjects drank 750ml of
tea each day. The cure appears to differentiate
itself from other current type-2 diabetes
treatments because the tea does not initially affect the sugar content of the
blood. But after four months of treatment with tea we can, however, see a
significant increase in glucose tolerance ... 'n the patient group who drank the
tea, the number of polyunsaturated fatty acids increased. That is good for the
body's cells because the polyunsaturated fat causes the cell membranes to be
more permeable, which results in the cells absorbing glucose better from the
blood" - See

Vitamin D Causes Problems For Acutely Ill Patients - Science Daily, 4/30/09
- "45% of people in our ICU were
Vitamin D deficient ... When the team
correlated the Vitamin D levels with a disease severity score, there was a
direct correspondence between sickness and Vitamin D deficiency. In other words,
the sicker someone was, the lower the levels of Vitamin D. Out of the 42
patients studied, there were 3 deaths. The 3 patients who died all had the
lowest level of Vitamin D in the cohort" - See

Associations
of dietary long-chain n-3 polyunsaturated fatty acids and fish with biomarkers
of inflammation and endothelial activation (from the Multi-Ethnic Study of
Atherosclerosis [MESA]) - Am J Cardiol. 2009 May 1;103(9):1238-43 -
"Long-chain n-3 PUFA
intake was inversely associated with plasma concentrations of interleukin-6 (p =
0.01) and matrix metalloproteinase-3 (p = 0.03) independent of age, body mass
index, physical activity, smoking, alcohol consumption, and dietary variables.
Nonfried fish consumption was inversely related to C-reactive protein (p =
0.045) and interleukin-6 (p <0.01) ... the results of this study suggest that
the dietary intake of long-chain n-3 PUFAs and fish is inversely associated with
concentrations of some biomarkers, reflecting lower levels of
inflammation and endothelial activation.
These results may partially explain the cardioprotective effects of fish
consumption"

Quercetin reduces systolic blood pressure and plasma oxidised low-density
lipoprotein concentrations in overweight subjects with a high-cardiovascular
disease risk phenotype: a double-blinded, placebo-controlled cross-over study
- Br J Nutr. 2009 Apr 30:1-10 -
"Subjects were randomised to receive 150 mg
quercetin/d in a double-blinded, placebo-controlled cross-over trial with 6-week
treatment periods separated by a 5-week washout period. Mean fasting plasma
quercetin concentrations increased from 71 to
269 nmol/l (P < 0.001) during quercetin treatment. In contrast to placebo,
quercetin decreased systolic blood pressure (SBP) by 2.6 mmHg (P < 0.01) in the
entire study group, by 2.9 mmHg (P < 0.01) in the subgroup of hypertensive
subjects and by 3.7 mmHg (P < 0.001) in the subgroup of younger adults aged
25-50 years. Quercetin decreased serum HDL-cholesterol concentrations (P <
0.001), while total cholesterol, TAG and the LDL:HDL-cholesterol and
TAG:HDL-cholesterol ratios were unaltered. Quercetin significantly decreased
plasma concentrations of atherogenic oxidised LDL, but did not affect TNF-alpha
and C-reactive protein when compared with placebo ... Blood parameters of liver
and kidney function, haematology and serum electrolytes did not reveal any
adverse effects of quercetin. In conclusion, quercetin reduced
SBP and plasma oxidised LDL concentrations in overweight subjects with a
high-CVD risk phenotype. Our findings provide further evidence that quercetin
may provide protection against CVD" - See

The effect
of n-3 long-chain polyunsaturated fatty acid supplementation on urine protein
excretion and kidney function: meta-analysis of clinical trials - Am J Clin
Nutr. 2009 Apr 29 - "The dose of
n-3 LCPUFAs ranged from 0.7 to 5.1 g/d, and
the median follow-up was 9 mo. In the pooled analysis, there was a greater
reduction in UPE in the n-3 LCPUFA group than in the control group: Cohen's d
for all trials was -0.19 (95% CI: -0.34, -0.04; P = 0.01). In a patient with 1 g
UPE/d , this corresponds to a reduction of 190 mg/d. Effects on
GFR were reported in 12 trials. The
decline in GFR was slower in the n-3 LCPUFA group than in the control group, but
this effect was not significant (0.11; 95% CI: -0.07, 0.29; P = 0.24)"

Mega Twin EPA at Amazon.com Low Serum Testosterone and Estradiol Predict Mortality in Elderly Men - J Clin Endocrinol Metab. 2009 Apr 28 - "mean follow-up period of 4.5 years ... low levels (within quartile 1; versus quartiles 2-4) of both testosterone (hazard ratio [HR] 1.65, 95% confidence interval [CI] 1.29-2.12) and estradiol (HR 1.54, 95% CI 1.22-1.95) associated with mortality. A model including both hormones showed that both low testosterone (HR 1.46, 95% CI 1.11-1.92) and estradiol (HR 1.33, 95% CI 1.02-1.73) predicted mortality. Risk of death nearly doubled (HR 1.96, 95% CI 1.46-2.62) in subjects with low levels of both testosterone and estradiol compared with subjects within quartiles 2-4 of both hormones ... Elderly men with low serum testosterone and estradiol have increased risk of mortality, and subjects with low values of both testosterone and estradiol have the highest risk of mortality"

Marine n-3
fatty acids promote size reduction of visceral adipose depots, without altering
body weight and composition, in male Wistar rats fed a high-fat diet - Br J
Nutr. 2009 Apr 28:1-12 - "Wistar rats fed a high-fat
diet. Rats were fed diets including lard (19.5 % lard) or
n-3 FA (9.1 % lard and 10.4 % Triomar) for 7
weeks. Feed consumption and weight gain were similar, whereas plasma lipid
concentrations were lower in the n-3 FA group. Magnetic resonance imaging
revealed smaller visceral (mesenteric, perirenal
and epididymal) adipose depots in the n-3 FA-fed animals (35, 44 and 32 %
reductions, respectively). n-3 FA feeding increased mRNA expression of cytokines
as well as chemokines in several adipose depots. Expression of Adipoq and Pparg
was enhanced in the mesenteric adipose depots of the n-3 FA-fed rats, and
fasting plasma insulin levels were lowered. Expression of the lipogenic enzymes
Acaca and Fasn was increased in the visceral adipose depots, whereas Dgat1 was
reduced in the perirenal and epididymal depots. Cpt2 mRNA expression was almost
doubled in the mesenteric depot and liver. Carcass analyses showed similar body
fat (%) in the two feeding groups, indicating that n-3 FA feeding led to
redistribution of fat away from the visceral compartment"
