Recent Longevity News for the seven days ending 7/2/08.  You should consult your doctor if you are taking any medications.

Post-exercise Caffeine Helps Muscles Refuel - Science Daily, 7/1/08 - "Recipe to recover more quickly from exercise: Finish workout, eat pasta, and wash down with five or six cups of strong coffee ... Athletes who ingested caffeine with carbohydrate had 66% more glycogen in their muscles four hours after finishing intense, glycogen-depleting exercise, compared to when they consumed carbohydrate alone" - Yeah, if you want to fell like crap for the rest of the day.  I drink by caffeine before the workout then again after a power nap. See:

  • Extra Sleep Improves Athletic Performance - Science Daily, 6/9/08 - "Getting extra sleep over an extended period of time improves athletic performance, mood and alertness ... The athletes then extended their sleep to 10 hours per day for six to seven weeks ... After obtaining extra sleep, athletes swam a 15-meter meter sprint 0.51 seconds faster, reacted 0.15 seconds quicker off the blocks, improved turn time by 0.10 seconds and increased kick strokes by 5.0 kicks"

Low Levels Of Good Cholesterol Linked To Memory Loss, Dementia Risk - Science Daily, 6/30/08 - "Researchers defined low HDL as less than 40 mg/dL ... At age 60, participants with low HDL had a 53 percent increased risk of memory loss compared to the high HDL group" - [WebMD] - The best way to increase HDL is niacin.  See niacin at Amazon.com.  Start slow maybe even with the 100 mg capsules.  It took me about three months to get immune to the flush from 2000 mg per day.  Taking it with soup seems to be the best.

Single Mechanism For Hypertension, Insulin Resistance And Immune Suppression - Science Daily, 6/30/08 - "spontaneously hypertensive rat (SHR) ... protein receptors on the surface of SHR cells become clipped off as the animals develop hypertension. They used a novel visualization technique to show that after several weeks of ingesting doxycycline in their drinking water, the SHR rats developed cells that again bristled with normal CD18 and insulin receptors. The animals' metabolic conditions simultaneously improved; blood pressure normalized and symptoms of immune suppression disappeared" - Note: I was taking Periostat (low dose doxycycline, 20 mg) for two reasons, the help prevent gum disease and to lower CRP.  Now I have a third reason.  See doxycycline at OffshoreRx1.com (you can use a pill cutter to quarter the pills).  See:

  • Low-dose Periostat (Doxycycline) Shows Benefits in Patients with Heart Failure - Doctor's Guide, 11/20/02 - "At six-month follow-up, sub-antimicrobial dose doxycyline significantly reduced CRP levels by 45.8 percent compared to baseline values (p<0.05). The drug was also associated with a 33.5 percent reduction in interleukin-6 and a 50 percent reduction in metalloproteinase ... The findings are exciting, since research is now showing that CRP is both a key marker of inflammation leading to future acute coronary events, but also that CRP itself may contribute to the initiation and progression of atherosclerosis"
    • Blood Protein Predicts Stroke Risk - HealthDay, 6/23/03 - "whether the substance [CRP] is an independent risk factor for these episodes or merely a reflection of narrowed and crumbling arteries hasn't been entirely clear ... New research now suggests that the molecule, called C-reactive protein (CRP), is indeed its own oddsmaker ... The cholesterol-fighting drugs known as statins have been shown to lower CRP by about 25 percent or so, Stein says. However, it's not clear that that effect reduces cardiovascular trouble or increases survival"

Could Caffeine Stop MS in Its Tracks? - WebMD, 6/30/08 - "When consumed in large amounts in a newly reported study, caffeine was found to protect against multiple sclerosis by blocking key steps in the development of the disease"

Shiitake Mushrooms May Improve Human Immune Function, Especially If Grown On Old Oak Logs - Science Daily, 6/29/08 - "These mushrooms contain high-molecular-weight polysaccharides (HMWP), which some studies suggest may improve human immune function. Other research indicates that the shiitake compound eritadenine may help lower cholesterol levels" - See shiitake mushroom supplements at Amazon.com.

Calcium Alone Does Not Reduce Hip Fracture Risk - Science Daily, 6/29/08 - "a recent analysis of several studies found no reduction in risk of hip fracture with calcium supplementation ... Future studies of fracture prevention should focus on the best combination of calcium plus vitamin D, rather than on calcium supplementation alone"

Israeli Study: Drinking Red Wine May Improve Meat's Healthfullness - Science Daily, 6/27/08 - "The rats that had eaten the turkey meat without the wine had high levels of chemicals that promote oxidation, which has been linked to cancer, atherosclerosis, and other serious disease ... the rats that got the turkey meat and the red wine had less of those oxidation chemicals in their stomach and blood after their meal"

Higher Coffee Consumption Associated With Lower Liver Cancer Risk - Science Daily, 6/26/08 - "0-1 cup, 2-3 cups, 4-5 cups, 6-7 cups, and 8 or more cups per day ... The researchers noted a significant inverse association between coffee drinking and the risk of primary liver cancer. They found that the multivariable hazards ratio of liver cancer dropped for each group that drank more coffee. It fell from 1.00, to .66, to .44, to .38 to .32 respectively"

Potential Role Of Fish-based Fatty Acids In Resolving, Preventing Asthma - Science Daily, 6/24/08 - "a molecule produced by the body from omega-3 fatty acids helps resolve and prevent respiratory distress in laboratory mice" - See Mega Twin EPA at Amazon.com.

Abstracts from this week's Doctor's Guide Nutrition/Dietetics plus abstracts from my RSS feeds (Click here for the journals, the PubMed ones at the top):

Advanced glycation end products and diabetic foot disease - Diabetes Metab Res Rev. 2008 May-Jun;24 Suppl 1:S19-24 - "recent clinical studies have shown that the AGE-breakers may be able to decrease adverse vascular effects of glycation with few side effects"

Resveratrol reduces endothelial progenitor cells senescence through augmentation of telomerase activity by Akt-dependent mechanisms - Br J Pharmacol. 2008 Jun 30 - "Resveratrol significantly increased telomerase activity and Akt phosphorylation ... Resveratrol delayed the onset of EPC senescence and this effect was accompanied by activation of telomerase through the PI3K-Akt signalling pathway. The inhibition of EPCs senescence by resveratrol might protect EPCs against dysfunction induced by pathological factors in vivo and improve EPC functional activities in a way that may be important for cell therapy" - See resveratrol products at Amazon.com.

Assessing the effect of docosahexaenoic acid on cognitive functions in healthy, preschool children: a randomized, placebo-controlled, double-blind study - Clin Pediatr (Phila). 2008 May;47(4):355-62 - "Regression analysis, however, yielded a statistically significant positive (P = .018) association between the blood level of docosahexaenoic acid and higher scores on the Peabody Picture Vocabulary Test, a test of listening comprehension and vocabulary acquisition" - See Jarrow Max DHA at Amazon.com.

Panax Ginseng Enhances Cognitive Performance in Alzheimer Disease - Alzheimer Dis Assoc Disord. 2008 Jun 17 - "ginseng group was treated with Panax ginseng powder (4.5 g/d) for 12 weeks ... After ginseng treatment, the cognitive subscale of ADAS and the MMSE score began to show improvements and continued up to 12 weeks (P=0.029 and P=0.009 vs. baseline, respectively). After discontinuing ginseng, the improved ADAS and MMSE scores declined to the levels of the control group. These results suggest that Panax ginseng is clinically effective in the cognitive performance of AD patients" - See ginseng at Amazon.com.

Neat Tech Stuff :

  • Andy Grove Offers an Energy Solution - New York Times Blog, 6/27/08 - "Pickups, SUVs, vans, and the like represent about 80 million vehicles, with mileage of perhaps 13 to 16 miles per gallon,” he writes. “Converting those should be our first priority ... A modest change in the worst offenders from an energy efficiency point of view, would have the biggest impact: Converting the worst gas guzzlers to use electricity even for as little as 50 miles of driving range on a daily basis could cut petroleum imports by 50 to 60 percent, Mr. Grove states"
