Recent Longevity News for the seven days ending 3/19/08.  You should consult your doctor if you are taking any medications.

My toll free number has chanced to 866-573-4699.  When I switched over to Vonage I was able to keep my local number but when I selected the Vonage toll free number, I had to change that number.  I didn't have any takers for Vonage.  That surprised me.  I don't understand why anyone with broadband would not get it.  I don't get why anyone would watch Judge Judy make rude, sarcastic remarks for an hour every night or why people think the economy is more important than preventing terrorists nukes from reaching US soil either.  I guess I have to take some psychology courses.  Click here form my Vonage review.  I let my roommate have the magicJack number so now whenever that phone rings she knows it is for her plus there is no hassle when my home phone gets forwarded to my cell.  Vonage just added a contact book that allows you to easily call up to 5 people at once or set up something similar to reverse 911 where you record your message and it calls and plays it to multiple contacts.  It's got SimulRing® that allows up to 5 other phone to ring when your Vonage phone rings. It's got Voice Activated Dialing that actually works the first time.  My Verizon Razor phone takes several tries for that to work.  You can add multiple Home Pages to Microsoft Internet Explorer.  I added the Vonage contact book so that it is always handy.

Could foods prevent ovarian cancer? - MSNBC, 3/14/08 - "Kaempferol — a flavonoid found in tea, broccoli, kale and spinach — and luteolin — which is provided by peppers, carrots, cabbage and celery — were both identified as cancer protective. Women who consumed the most of these two flavonoids were 40 percent and 34 percent less likely, respectively, to develop ovarian cancer compared to women who consumed the least ... A 2007 study published in the British Journal of Nutrition linked greater consumption of carotenoid phytochemicals with a 67 percent lower risk of ovarian cancer. This included not only beta-carotene, the oft-cited carotenoid in deep-orange vegetables and fruits, but also alpha-carotene, beta-cryptoxanthin, lutein and zeaxanthin — carotenoids found in a wide range of red, orange, yellow and green vegetables" - See Jarrow Formulas, CarotenALL, Mixed Carotenoid Complex at Amazon.com.

DHEAS Levels Linked to Cognitive Function in Women - Medscape, 3/13/07 - "There are data that suggest that DHEA and DHEAS may have neuroprotective effects and that the decline in the production of these steroids with healthy aging may contribute to neuronal dysfunction and degeneration, and thus cognitive decline ... women with higher circulating levels of DHEAS performed better on executive function tests. A positive association was also observed between circulating DHEAS and higher scores on tests of simple concentration and working memory in women with more than 12 years of education" - See DHEA at Amazon.com.

How Diabetes Drives Atherosclerosis - WebMD, 3/13/08 - "Abe's team showed that molecules called advanced glycation end products (AGEs), produced in greater levels by patients with diabetes, interfere with ERK5 cardioprotection. Glycation reactions cause the release of oxidizing side products like hydrogen peroxide (H202) that drive free radical production, inflammation and cell damage in many diseases" - I was always under the impression that it was advanced glycation end products in the first place.  I guess I was right before they discovered it.

Telmisartan treatment decreases visceral fat accumulation and improves serum levels of adiponectin and vascular inflammation markers in Japanese hypertensive patients - Hypertens Res. 2007 Dec;30(12):1205-10 - "telmisartan treatment was associated with an improvement of vascular inflammation, reductions in visceral fat and increases in serum adiponectin"

Effects of curcumin on bladder cancer cells and development of urothelial tumors in a rat bladder carcinogenesis model - Cancer Lett. 2008 Mar 12 - "Exposure of human bladder cancer cells to curcumin resulted in the induction of apoptotic cell death and caused cells to arrest in the G2/M phase. The anti-apoptotic Bcl-2 and Survivin protein was downregulated by the curcumin treatment together with enhancement of the Bax and p53 expression. The inhibitory activities of curcumin were stronger than those of cisplatin and could not be prevented by catalase pretreatment in T24 cells. Clonal assay indicated large-dose and short-term curcumin was lethal to bladder cancer cells. Moreover, the in vivo study revealed curcumin did induce apoptosis in situ, inhibit and slow the development of bladder cancer. These observations suggest that curcumin could prove an effective chemopreventive and chemotherapy agent for bladder cancer" - curcumin products at Amazon.com.

Lipoic acid supplementation and endothelial function - Br J Pharmacol. 2008 Mar 17 - "Endothelial dysfunction is caused by all the recognized cardiovascular risk factors and has been implicated in the complex processes leading to the initiation and progression of atherosclerosis. Short-term treatment with lipoic acid is shown in the current issue of the British Journal of Pharmacology to improve endothelial function of aortic rings of old rats. The age-related decrease in phosphorylation of nitric oxide synthase and Akt was improved by lipoic acid supplementation. The improved phosphorylation status may have been due to reduced activity of the phosphatase PPA2, associated with decreased levels of endothelial ceramide induced by lipoic acid. Neutral sphingomyelinase activity was also reduced by lipoic acid, which was due, at least in part, to increased glutathione levels in endothelial cells" - alpha lipoic acid at Amazon.com.

Effect of tea catechins on body fat accumulation in rats fed a normal diet - Biomed Res. 2008 Feb;29(1):27-32 - "The administration of 0.5% catechins decreased the accumulation of body fat and the serum levels of cholesterol and bile acids.

Peroxisome Proliferator-Activated Receptor gamma agonism modifies the effects of growth hormone on lipolysis and insulin sensitivity - Clin Endocrinol (Oxf). 2008 Mar 10 - "Peroxisome Proliferator-Activated Receptor gamma (PPARgamma) agonists such as thiazolidinediones (TZD) improve insulin sensitivity in type 2 diabetes via effects on fat metabolism, whereas growth hormone (GH) stimulates lipolysis and induces insulin resistance ...Randomized, placebo-controlled, double-blind parallel-group study including 20 GH-deficient patients on continued GH replacement therapy. The patients were studied before and after 12 weeks ... Adiponectin levels almost doubled during pioglitazone treatment (P = 0.0001). Pioglitazone significantly decreased basal free fatty acid levels (P = 0.02) and lipid oxidation (P = 0.02). Basal glucose oxidation rate (P = 0.004) and insulin sensitivity (P = 0.03) improved in the patients who received pioglitazone treatment. The change in insulin-stimulated adiponectin level after pioglitazone treatment was positively correlated to the change in insulin-stimulated total glucose disposal (R = 0.69 ... The impact of GH on lipolysis and insulin sensitivity is modifiable by administration administration of TZD" - See pioglitazone at OffshoreRx1.com.

The PPARgamma agonist pioglitazone is effective in the MPTP mouse model of Parkinson's disease through inhibition of monoamine oxidase B - Br J Pharmacol. 2008 Mar 10 - "The peroxisome proliferator-activated receptor-gamma (PPARgamma) agonist pioglitazone has previously been shown to attenuate dopaminergic cell loss in the 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) mouse model of Parkinson's disease, an effect attributed to its anti-inflammatory properties. In the present investigation, we provide evidence that pioglitazone is effective in the MPTP mouse model, not via an anti-inflammatory action, but through inhibition of MAO-B, the enzyme required to biotransform MPTP to its active neurotoxic metabolite 1-methyl-4-phenylpyridinium (MPP+) ... Mice treated with MPTP showed deficits in motor performance, marked depletions in striatal dopamine levels and a concomitant reduction in TH immunoreactivity in the substantia nigra. Pretreatment with pioglitazone completely prevented these effects of MPTP. However, pretreatment with pioglitazone also significantly inhibited the MPTP-induced production of striatal MPP+ and the activity of MAO-B in the striatum" - See pioglitazone at OffshoreRx1.com.

Resveratrol protects against arsenic trioxide-induced cardiotoxicity in vitro and in vivo - Br J Pharmacol. 2008 Mar 10 - "The clinical use of arsenic trioxide (As(2)O(3)), a potent antineoplastic agent, is limited by its severe cardiotoxic effects ... resveratrol significantly attenuated As(2)O(3)-induced QT prolongation, structural abnormalities and oxidative damage in the heart. In H9c2 cardiomyocytes, resveratrol also decreased apoptosis, production of ROS and intracellular calcium mobilization induced by treatment with As(2)O(3). These observations suggested that resveratrol has the potential to protect against cardiotoxicity in As(2)O(3)-exposed patients" - See resveratrol products at Amazon.com.

Folate and MTHFR: risk of adenoma recurrence in the Polyp Prevention Trial - Cancer Causes Control. 2008 Mar 6 - "Low dietary folate intake has been associated with colorectal cancer risk and adenoma recurrence. A C/T transition at position 677 in the gene encoding methlylenetetrahydrofolate reductase (MTHFR C677T) has been reported to interact with folate intake to modulate colorectal adenoma recurrence or cancer risk ... In general, no statistically significant associations were found between quartile of folate intake (dietary or total) and adenoma recurrence ... No significant interaction was noted for total folate and MTHFR genotype, though an increased risk of recurrence noted for the MTHFR CT genotype was statistically significant only for those individuals with below median intake of total folate"

• Errant Enzyme Causes Big Bellies - WebMD, 12/11/01 - "They looked at an enzyme called 11-beta hydroxysteroid dehydrogenase type 1. This enzyme is able to increase the level of cortisol in fat cells without raising the level of cortisol in the blood ... The researchers genetically engineered mice that overproduce this enzyme. They made sure that the level of the enzyme was equivalent to the level previously found in the fatty tissue of overweight humans. As expected, the mice produced extra amounts of cortisol in their fat cells, but not in their blood ... The next step was to compare these mice to mice that produced normal amounts of the enzyme. Even when fed a low-fat diet, the genetically-altered mice developed a pot belly while the normal mice did not. The problem was even worse when the altered mice were fed a high-fat diet ... We were surprised to find that it took only a modest increase in this enzyme to cause the mice to become ... obese"
