Recent Longevity News for the seven days ending 4/21/10.  You should consult your doctor if you are taking any medications.

Alfuzosin Improves Ejaculatory Dysfunction in Men With Probable BPH - Medscape, 4/20/10 - "Alfuzosin (Uroxatral, Sanofi Aventis), a uroselective alpha-1-adrenergic receptor blocker, ameliorates ejaculatory dysfunction in sexually active men with lower urinary tract symptoms (LUTS) suggestive of benign prostatic hypertrophy (BPH) ... Alfuzosin significantly improved IPSS score (7.9 [–41%]; P < .0001) and nocturia (–0.9 [–18%]; P < .001) from baseline. Bother due to LUTS also significantly improved (–1.5 [–28%]; P < .0001)"

Vitamin K may protect against developing non-Hodgkin's lymphoma, say Mayo Clinic researchers - Science Daily, 4/19/10 - "the risk of developing Non-Hodgkin lymphoma was approximately 45 percent lower for participants who had vitamin K intakes in the top quartile of intake in the study (>108 ug/day), compared to participants who had intakes in the bottom quartile (<39 ug/day). This association remained after accounting for other factors such as age, sex, education, obesity, smoking, alcohol use and intake of foods with high amounts of antioxidants"

Vitamin and calcium supplements may reduce breast cancer risk - Science Daily, 4/18/10 - "It is not an immediate effect. You don't take a vitamin today and your breast cancer risk is reduced tomorrow ... Vitamin supplements appeared to reduce the risk of breast cancer by about 30 percent"

First evidence that chitosan could repair spinal damage - Science Daily, 4/16/10 - "Cho was amazed to see that the spinal cord was completely dark. None of the dye had entered the nerve cells. Chitosan had repaired the damaged cell membranes ... Next Cho tested whether a dose of chitosan could prevent large molecules from leaking from damaged spinal cord cells. Testing for the presence of the colossal enzyme lactate dehydrogenase (LDH), Borgens admits he was amazed to see that levels of LDH leakage from chitosan treated spinal cord were lower than from undamaged spinal cords. Not only had the sugar repaired membranes at the compression site but also at other sites where the cell membranes were broken due to handling. And when the duo tested for the presence of harmful reactive oxygen species (ROS), released when ATP generating mitochondria are damaged, they found that ROS levels also fell after applying chitosan to the damaged tissue: chitosan probably repairs mitochondrial membranes as well as the nerve cell membranes"

Statins May Lower Testosterone, Libido - WebMD, 4/16/10 - "When they compared men on statins to those not, the men on statins were twice as likely to have low testosterone, regardless of which of three commonly used thresholds for low testosterone they looked at"

Low Vitamin D Level Tied to Cognitive Decline - WebMD, 4/16/10 - "Two new studies add to evidence that older people with low levels of vitamin D may be more likely to suffer from cognitive impairment. ... Results showed that the lower their score on the test, the lower their vitamin D levels" - See vitamin D at Amazon.com.

Diet high in B vitamins lowers heart risks in Japanese study - Science Daily, 4/15/10 - "The findings on the value of B vitamins were consistent with studies in Europe and North America, although the dietary consumption of vitamin B-6 is generally lower in Japan than in the United States ... Comparing those with the diets lowest and highest for each nutrient, they found that higher consumption of folate and vitamin B-6 was associated with significantly fewer deaths from heart failure in men, and significantly fewer deaths from stroke, heart disease and total cardiovascular diseases in women"

Low vitamin D levels associated with more asthma symptoms and medication use - Science Daily, 4/15/10 - "Low levels of vitamin D are associated with lower lung function and greater medication use in children with asthma ... vitamin D enhances the activity of corticosteroids, the most effective controller medication for asthma ... Patients low in vitamin D generally had higher levels of IgE, a marker of allergy, and responded positively to more allergens in a skin prick test" - See vitamin D at Amazon.com.

Calorie restriction leads scientists to molecular pathways that slow aging, improve health - Science Daily, 4/15/10 - "About 30 percent of the animals on calorie restriction die at an advanced age without any diseases normally related to aging," Fontana says. "In contrast, among animals on a standard diet, the great majority (94 percent) develop and die of one or more chronic diseases such as cancer or heart disease. In 30 percent to 50 percent of the animals on calorie restriction, or with genetic mutations in these aging-related pathways, healthspan is equal to lifespan. They eventually die, but they don't get sick." - Note:  See my calorie restriction page.  It's debatable whether it works in humans.  For example, here's another study:

  • Overweight Older People Live Longer - WebMD, 1/28/10 - "people who met the criteria for being overweight were 17% less likely to die compared to people of normal weight ... In the newly reported research, overweight study participants in their 70s followed for up to 10 years had a 13% lower risk of death than participants classified as normal weight ... Obese and normal-weight study participants had a similar risk of death over the 10 years of follow-up. Underweight study participants had the highest risk of death, even after the researchers adjusted for the wasting effects of disease"

Lack of omega-6 fatty acid linked to severe dermatitis - Science Daily, 4/14/10 - "Without arachidonic acid, the mice developed severe ulcerative dermatitis. The animals were very itchy, they scratched themselves continuously, and they developed a lot of bleeding sores" - Note:  I doubt if that's a problem in America where they get way to much omega-6 already.

Women in the placebo group lost an average of 1.4 kilos. In addition, women with NAFLD experienced improvements in waist circumference, body and liver fat content, liver enzymes, and serum triglycerides" - [Abstract] - 5.5 kg is 12.1 pounds - See FucoThin at Amazon.com
  • The effects of Xanthigen in the weight management of obese premenopausal women with non-alcoholic fatty liver disease and normal liver fat - Diabetes Obes Metab. 2010 Jan;12(1):72-81 - "Xanthigen-600/2.4 mg (300 mg PSO + 300 mg brown seaweed extract containing 2.4 mg fucoxanthin) resulted in statistically significant reduction of body weight (5.5 +/- 1.4 kg NAFLD group and 4.9 +/- 1.2 kg NLF group, p < 0.05), waist circumference (NAFLD group only), body (3.5 +/- 1.9 kg NAFLD group, p < 0.001; 3.6 +/- 0.7 kg NLF group, p < 0.05) and liver fat content, liver enzymes (NAFLD group only), serum triglycerides and C-reactive protein. Weight loss and reduction in body and liver fat content occurred earlier in patients with NLF than in patients with NAFLD. Fucoxanthin (> 2.4 mg) and Xanthigen-400/1.6 mg (200 mg PSO + 200 mg brown seaweed extract containing 1.6 mg fucoxanthin) significantly increased REE in NAFLD subjects compared to placebo. CONCLUSIONS: Xanthigen promoted weight loss, reduced body and liver fat content, and improved liver function tests in obese non-diabetic women. Xanthigen and Fucoxanthin also increased REE. This product may be considered a promising food supplement in the management of obesity" - See FucoThin at Amazon.com
  • Dietary Fiber May Help Prevent Body Weight, Waist Circumference Gain - Medscape, 1/6/10 - "There was an inverse association of total fiber intake with subsequent change in weight and in waist circumference. For each 10-g/day increase in total fiber intake, the pooled estimate was –39 g/year (95% confidence interval [CI], –71 to –7 g/year) for weight change and –0.08 cm/year (95% CI, –0.11 to –0.05 cm/year) for waist circumference change ... For each 10-g/day increase in fiber intake from cereals, there was a weight change of –77 g/year (95% CI, –127 to –26 g/year) and change in waist circumference of –0.10 cm/year (95% CI, –0.18 to –0.02 cm/year). Fruit and vegetable fiber was not associated with weight change. However, the association of fruit and vegetable fiber intake with change in waist circumference was similar to that seen for intake of total dietary fiber and cereal fiber"
  • Whole-Grain Intake and Cereal Fiber Are Associated with Lower Abdominal Adiposity in Older Adults - J Nutr. 2009 Sep 2 - "After adjustment for covariates, whole-grain intake was inversely associated with BMI [26.8 kg/m(2) (25.7-28.1) vs. 25.8 kg/m(2) (24.6-27.1), (95% CI); P-trend = 0.08], percent body fat [34.5% (32.7-36.3) vs. 32.1% (30.1-34.1); P-trend = 0.02], and percent trunk fat mass [43.0% (40.4-45.5) vs. 39.4% (36.7-42.1); P-trend = 0.02] in the lowest compared with the highest quartile category of whole-grain intake. Refined grain intake was not associated with any measure of body fat distribution. Cereal fiber was inversely associated with BMI [27.3 kg/m(2) (26.1-28.6) vs. 25.4 kg/m(2) (24.3-26.7); P-trend = 0.012], percent body fat [34.7% (32.8-36.6) vs. 31.5% (29.4-33.5); P-trend = 0.004], and percent trunk fat mass [42.8% (40.2-45.4) vs. 37.8% (35.0-40.6) ... Higher intakes of cereal fiber, particularly from whole-grain sources, are associated with lower total percent body fat and percent trunk fat mass in older adults"
  • Successful Weight Loss With Dieting Is Linked To Vitamin D Levels - Science Daily, 6/11/09 - "the authors found that baseline, or pre-diet, vitamin D levels predicted weight loss in a linear relationship. For every increase of 1 ng/mL in level of 25-hydroxycholecalciferol—the precursor form of vitamin D and a commonly used indicator of vitamin D status—subjects ended up losing almost a half pound (0.196 kg) more on their calorie-restricted diet. For each 1-ng/mL increase in the active or "hormonal" form of vitamin D (1,25-dihydroxycholecalciferol), subjects lost nearly one-quarter pound (0.107 kg) more ... Additionally, higher baseline vitamin D levels (both the precursor and active forms) predicted greater loss of abdominal fat" - See vitamin D at Amazon.com.
  • Conjugated Linoleic Acids Reduce Body Fat in Healthy Postmenopausal Women - J Nutr. 2009 Jun 3 - "Isomers of conjugated linoleic acids (CLA) reduce fat mass (FM) and increase insulin sensitivity in some, but not all, murine studies. In humans, this effect is still debatable. In this study, we compared the effect of 2 CLA supplements on total and regional FM assessed by dual energy X-ray absorptiometry, changes in serum insulin and glucose concentrations, and adipose tissue (AT) gene expression in humans. In a double-blind, parallel, 16-wk intervention, we randomized 81 healthy postmenopausal women to 1) 5.5 g/d of 40/40% of cis9,trans11-CLA (c9,t11-CLA) and trans10,cis12-CLA (t10,c12-CLA) (CLA-mix); 2) cis9, trans11-CLA (c9,t11-CLA); or 3) control (olive oil) ... The CLA-mix group had less total FM (4%) and lower-body FM (7%) than the control (P = 0.02 and < 0.001, respectively). Post hoc analyses showed that serum insulin concentrations were greater in the CLA-mix group (34%) than the control group (P = 0.02) in the highest waist circumference tertile only ... In conclusion, a 50:50 mixture of c9,t11- and t10,c12-CLA isomers resulted in less total and lower-body FM in postmenopausal women and greater serum insulin concentrations in the highest waist circumference tertile" - See conjugated linoleic acid at Amazon.com.  As with all CLA studies, I wish they would state brand names instead of leaving it to the reader to figure out which mixture corresponds to which brand name.  I've seen studies where some isomers increase insulin sensitivity while others have the opposite effect.
  • Dietary Supplementation of L-Arginine and Conjugated Linoleic Acid Reduces Retroperitoneal Fat Mass and Increases Lean Body Mass in Rats - J Nutr. 2009 May 13 - "We conclude that CLA and arginine modulated adipose tissue metabolism by separate, but not additive, effects. Also, CLA and arginine may have depressed muscle protein turnover" - See conjugated linoleic acid at Amazon.com and L-arginine products at Amazon.com.
  • Whole-Grain, Low-Calorie Diet Reduced Body Fat Compared With Refined-Wheat Low-Calorie Diet - Doctor's Guide, 5/14/09 - "Patients consuming whole-grain foods had a significantly larger drop in body fat percentage (assessed by dual-energy x-ray absorptiometry scanning) compared with patients who had eaten refined foods (-6.8% vs -4.8%; P = .03) ... Total cholesterol and LDL cholesterol levels rose by 5% in the refined-wheat group but remained unchanged in the wholemeal-wheat group"
  • Study In Pregnant Women Suggests Probiotics May Help Ward Off Obesity - Science Daily, 5/7/09 - "One year after giving birth, women were less likely to have the most dangerous kind of obesity if they had been given probiotics from the first trimester of pregnancy, found new research that suggests manipulating the balance of bacteria in the gut may help fight obesity ... Central obesity, where overall obesity is combined with a particularly fat belly, is considered especially unhealthy ... We found it in 25% of the women who had received the probiotics along with dietary counselling, compared with 43% in the women who received diet advice alone" - See probiotics at Amazon.com.
  • 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" - See Mega Twin EPA at Amazon.com and Jarrow Max DHA at Amazon.com.
  • Carotenoids may halve metabolic syndrome risk - Nutra USA, 4/23/09 - "Higher total carotenoid, beta-carotene, alpha-carotene, and lycopene intakes were associated with lower waist circumferences and visceral and subcutaneous fat mass ... Higher lycopene intake was related to lower serum triglyceride concentrations ... higher total carotenoid intakes, mainly those of beta-carotene and lycopene, were associated with a lower prevalence of metabolic syndrome and with lower measures of adiposity and serum triglyceride concentrations in middle-aged and elderly men" - [Abstract] - See Jarrow Formulas, CarotenALL, Mixed Carotenoid Complex at Amazon.com.
  • Dietary carotenoid intake is associated with lower prevalence of metabolic syndrome in middle-aged and elderly men - J Nutr. 2009 May;139(5):987-92 - "After adjustment for confounders, total carotenoid and lycopene intakes were inversely associated with presence of metabolic syndrome [relative risk (RR) quartile 4 vs. quartile 1 (95% CI) 0.42 (0.20-0.87), P-trend 0.02; and 0.55 (0.28-1.11), P-trend 0.01, respectively]. For beta-carotene, a decreased risk was observed for each quartile of intake compared with the first [RR quartile 4 vs. quartile 1 (95% CI) 0.58 (0.33-1.02)]. Higher total carotenoid, beta-carotene, alpha-carotene, and lycopene intakes were associated with lower waist circumferences and visceral and subcutaneous fat mass. Higher lycopene intake was related to lower serum triglyceride concentrations" - See Jarrow Formulas, CarotenALL, Mixed Carotenoid Complex at Amazon.com.
  • Blueberries May Banish Belly Fat - WebMD, 4/19/08 - "enriched with whole blueberry powder or carbohydrates as 2% of their total diet ...

  • Low Glycemic Breakfast May Increase Benefits Of Working Out - Science Daily, 4/15/09 - "Overall, fat oxidation was higher in the LGI treatment than in the HGI treatment (P < 0.05) during the post-breakfast and exercise periods. Following lunch, fullness scores were higher in the LGI trial than in the HGI trial (P < 0.05). The authors concluded that consuming a LGI breakfast increases fat oxidation during subsequent exercise and improved satiety during recovery in sedentary females. As such, individuals trying to shed fat may consider choosing LGI foods eaten prior to when they exercise"

  • Dietary L-Arginine Supplementation Reduces White Fat Gain and Enhances Skeletal Muscle and Brown Fat Masses in Diet-Induced Obese Rats - J Nutr. 2008 Dec 23 - "l-arginine-HCl ... Despite similar energy intake, absolute weights of white fat pads increased by 98% in control rats over a 12-wk period but only by 35% in arginine-supplemented rats. The arginine treatment reduced the relative weights of white fat pads by 30% and enhanced those of soleus muscle by 13%, extensor digitorum longus muscle by 11%, and brown fat by 34% compared with control rats ... arginine treatment resulted in lower serum concentrations of leptin, glucose, triglycerides, urea, glutamine, and branched-chain amino acids, higher serum concentrations of nitric-oxide metabolites, and improvement in glucose tolerance. Thus, dietary arginine supplementation shifts nutrient partitioning to promote muscle over fat gain and may provide a useful treatment for improving the metabolic profile and reducing body white fat in diet-induced obese rats" - See arginine products at Amazon.com.

  • Fat redistribution preferentially reflects the anti-inflammatory benefits of pioglitazone treatment - Metabolism. 2010 Jan 19 - "high-sensitivity C-reactive protein (hsCRP) ... Pioglitazone treatment for 12 weeks decreased serum hsCRP levels (0.83 [1.14] to 0.52 [0.82] mg/L, P < .001) and improved glycemic control (fasting glucose, P < .001; glycosylated hemoglobin, P < .001) and lipid profiles (triglyceride, P = .016; high-density lipoprotein cholesterol, P < .001). Between responders and nonresponders to the hsCRP-lowering effect of pioglitazone, there were significant differences in baseline hsCRP levels and changes in the postprandial glucose and the ratio of visceral fat thickness (VFT) to subcutaneous fat thickness (SFT) (P = .004, .011, and .001, respectively). The percentage change in hsCRP levels after treatment was inversely correlated with baseline hsCRP levels (r = -0.497, P < .001) and directly correlated with the change in postprandial glucose (r = 0.251, P = .021), VFT (r = 0.246, P = .030), and VFT/SFT ratio (r = 0.276, P = .015). Logistic regression analysis revealed that the hsCRP-lowering effect of pioglitazone was affected by baseline hsCRP levels (odds ratio [OR] = 7.929, P = .007) as well as changes in postprandial 2-hour glucose (OR = 0.716, P = .025) and VFT/SFT ratio (OR = 0.055, P = .009). In conclusion, treatment with pioglitazone produced an anti-inflammatory effect, decreasing serum hsCRP levels; and a decrease in the VFT/SFT ratio was independently and most strongly associated with the hsCRP-decreasing effect. These results suggest that abdominal fat redistribution preferentially reflects the anti-inflammatory benefits of pioglitazone treatment"
