Recent Longevity News for the seven days ending 2/22/12.  You should consult your doctor if you are taking any medications.

Fructose off the Hook for Overweight and Obesity? - WebMD, 2/20/12 - "The remaining 10 studies under review were based around adding calories. In each, half of the participants ate their usual diet, while the other half added fructose, a naturally occurring sweetener, to what they normally ate. The fructose groups did gain weight, but no more than would be expected from the amount of additional calories -- or energy -- that they took in as part of the studies ... Our data suggests that fructose plays the same role as any energy-dense substance"

The Body Odd - What's the lifespan of a singer's voice? - MSNBC, 2/17/12 - "vocal cords stiffen with age ... As the vocal membranes are used more, they become fibrous and stiff with a diminished amplitude of vibration" - Note: When I get the yearly checkup from my throat cancer, they stick a scope up your nose all the way down to your vocal cords and tell you to say “eeee”.  One doc remarked how strong my vocals were.  I do karaoke a lot so it would seem to throw out this theory.

Clinical trial supports CLA’s weight management in obese Chinese - Nutra USA, 2/17/12 - "Twelve weeks of supplementation produced an average 0.7 kg decrease in body weight and an average decrease in total body fat of 0.6 kg ... milk supplemented with CLA (3.4 g/d for 12 wk) ... used the Tonalin branded ingredient from BASF" - [Abstract] - See conjugated linoleic acid at Amazon.com.

Catechin-enriched green tea shows fat busting potential: RCT - Nutra USA, 2/17/12 - "Visceral fat levels decreased by 9.5 cm2 after twelve weeks of consuming the catechin-enriched beverage, compared with a control beverage with normal levels of green tea catechins" - See green tea extract at Amazon.com.

Organic food sweetener may be a hidden source of dietary arsenic - Science Daily, 2/16/12 - "Of the 17 toddler milk formulas tested, only two had listed organic brown rice syrup as the primary ingredient. These two formulas, one dairy-based and one soy-based, were extremely high in arsenic, more than 20 times greater than the other formulas. The amount of inorganic arsenic, the most toxic form, averaged 8.6 ppb for the dairy based formula and 21.4 ppb for the soy formula"

Flu may boost Alzheimer's risk, research suggests - MSNBC, 2/16/12 - "Viruses such as influenza and herpes may leave brain cells vulnerable to degeneration later in life, and increase the risk of developing diseases such as Alzheimer's and Parkinson's, research suggests. That's because these the viruses can enter the brain and trigger an immune response — inflammation — which can damage brain cells"

In the mouth, smoking zaps healthy bacteria - Science Daily, 2/15/12 - "They need a more aggressive form of treatment, because even after a professional cleaning, they're still at a very high risk for getting these pathogens back in their mouths right away"

Glass half empty: Is your tap water safe? - MSNBC, 2/15/12 - "Barium, chromium, copper, lead, nitrate, and other chemicals, as well as E. coli (E. coli!?), have been detected over the past year ... Antibiotics, hormones, a cancer drug, a chemical found in gasoline, antiseizure medication...research shows that hundreds of unregulated contaminants may be flowing from my tap ... a reverse-osmosis system filters out many EPA-regulated contaminants; and an ultraviolet filter kills bacteria and other microorganisms" - See water distillers at Amazon.com.

Is That ‘New Car Smell’ Toxic? - WebMD, 2/15/12 - "new car smell comes from toxic chemicals off-gassing in a car’s interior, like brominated flame retardants (BFRs), chromium, and lead ... At the top of the list for the most healthy car interior is the 2012 Honda Civic ... At the bottom of the list are the 2011 Mitsubishi Outlander Sport and 2011 Chrysler 200 SC"

  • Effects of Ginseng Rhizome and Ginsenoside Ro on Testosterone 5α-Reductase and Hair Re-growth in Testosterone-treated Mice - Phytother Res. 2011 May 2 - "Extracts of red ginseng rhizome showed greater dose-dependent inhibitory effects against testosterone 5α-reductase (5αR) when compared with extracts of the main root. Ginsenoside Ro, the predominant ginsenoside in the rhizome, and ginsenoside Rg(3) , a unique ginsenoside in red ginseng, showed inhibitory activity against 5αR with IC(50) values of 259.4 and 86.1 µm, respectively. The rhizome of P. japonicus, which contains larger amounts of ginsenoside Ro, also inhibited 5αR. Topical administration of extracts of red ginseng rhizomes (2 mg/mouse) and ginsenoside Ro (0.2 mg/mouse) to shaved skin inhibited hair re-growth suppression after shaving in the testosterone-treated C57BL/6 mice. These results suggest that red ginseng rhizomes containing both oleanane- and dammarane-type ginsenosides are a promising raw material for cosmetic use. This is the first report that ginsenoside Ro enhances in vivo hair re-growth based on their inhibitory activity against 5αR in the androgenetic alopecia model" - See ginseng at Amazon.com.

Conventional medicines used to treat male pattern baldness are designed to block the conversion of testosterone to DHT. Topical application of minoxidil (Rogaine®) and taking oral finasteride (Propecia®) have been shown to inhibit this conversion and to increase hair growth, but both medications have been linked with several adverse side effects, including fast heart rate, headaches, impotence, and decreased libido ... 400 mg of a standardized extract of saw palmetto and 100 mg of beta-sitosterol per day ...

  • Monthly Updates - Hair Loss Research, 10/01 - "While finasteride (Propecia/Proscar) decreases serum DHT, it also is thought to increase estrogen which suggests that men over 35 may want to consider using it in conjunction with a systemic aromatase inhibitor such as Chrysin/Piperine (Super Miraforte), Arimidex, or stinging nettle extract, to maximize its hair growth effects and minimize potential side effects (that are listed in the PDR) such as Gynocaemastia (breast enlargement in males), sexual side effects, and an increase in fat deposition. These compounds have been reliably shown to increase testosterone and reduce excess estrogen, resulting in a youthful hormone profile that optimizes immune function and to some degree, body composition"
  • Antiaging Products for Skin, Hair and Nails - Nutrition Science News, 10/00 - "A lack of silicon is known to reduce normal growth and repair of the skin, hair and nails.  However, studies show that silicon supplementation has delivered few benefits. The reason for this in most cases is that a nonbioavailable silicon source has been used. Silicon is a nonmetallic element that is very reactive. It occurs naturally almost exclusively in silicates, the geologic rock-forming minerals. Although silicates are the most abundant materials on earth, they don't provide a bioavailable form of dietary silicon. Moreover, silica, often used as a dietary supplement, is a polymeric silicon-hydroxide-oxide-water complex from hard stone, such as quartz, that has anywhere from two to trillions of silicon atoms, and is also very poorly bioavailable. On the other hand, orthosilicic acid, which consists of only one Si bonded to four hydroxides instead of oxygen, is the form of Si that is found in our bloodstream. Therefore, stabilized orthosilic acid is the only form of supplemental silicon that has been shown conclusively to be bioavailable for humans. Silicates, silica gel, colloidal silica, clays, horsetail (Equisetum arvense) and most foods don't contain the orthosilicic acid form of silicon."
  • Hair Graying and Loss - Nutrition Science News, 10/00 - "Japanese researchers found that topical application of procyanidin-B2 from grape seed and apple extracts activate hair follicles in mice, resulting in increased hair growth. Furthermore, Italian researchers found that a topical preparation containing esculin (an oxolinic acid) from horse chestnut (Aesculus hippocastanum) reduced hair loss and increased circulation to the hair follicles in men and women suffering from hair loss.3 Reduced scalp microcirculation is also one of the factors causing hair loss."
  • Essential Oils Can Help Regrow Hair - Nutrition Science News, 9/00
  • Proanthocyanidin Power - Nutrition Science News, 6/00 - "Japanese researchers shaved mice and found that 40 percent of their hair grew back naturally. When a 1 percent solution of any of three proanthocyanidins was applied to the skin, however, between 70 and 80 percent of the hair grew back. Test tube studies confirm that OPCs actually stimulate the hair keratinocytes to produce three times more hair than the controls."
  • Hair Loss- MinSaw-A, Nizoral and Dercos- The bald truth! - By Phil Micans PharmB - "the addition of retinolic acid (the active ingredient in the famous anti-wrinkle skin cream- Retin-A), helps to further stimulate the blood supply on the scalp surface and therefore to the hair follicle"

  • Latisse for your dome? Drug thickens thin hair - MSNBC, 11/14/11 - "The appeal of using Latisse for hair loss is its ease and convenience, as it seems to only require one drop to the affected area once a day ... The major drawback: It's expensive. Each 2-ounce bottle costs $100 to $150 — and some patients will run through two or three bottles a month"
  • Regrowing hair: Researchers may have accidentally discovered a solution - Science Daily, 2/16/11 - "a short-duration treatment with this compound causes an astounding long-term hair regrowth in chronically stressed mutant mice ... the researchers had been using mice that were genetically altered to overproduce a stress hormone called corticotrophin-releasing factor, or CRF. As these mice age, they lose hair and eventually become bald on their backs, making them visually distinct from their unaltered counterparts. The Salk Institute researchers had developed the chemical compound, a peptide called astressin-B, and described its ability to block the action of CRF. Stenzel-Poore had created an animal model of chronic stress by altering the mice to overproduce CRF ... researchers injected the astressin-B into the bald mice to observe how its CRF-blocking ability affected gastrointestinal tract function. The initial single injection had no effect, so the investigators continued the injections over five days to give the peptide a better chance of blocking the CRF receptors. They measured the inhibitory effects of this regimen on the stress-induced response in the colons of the mice and placed the animals back in their cages with their hairy counterparts ... About three months later, the investigators returned to these mice to conduct further gastrointestinal studies and found they couldn't distinguish them from their unaltered brethren. They had regrown hair on their previously bald backs" - Note:  To the best of my knowledge there's nothing non-experimental on the market, either conventional or alternative, that inhibits CRF.  If there were people would be taking it to reduce cortisol.
  • Drugs for hair loss and benign prostatic hyperplasia may result in loss of libido, erectile dysfunction in men - Science Daily, 1/11/11 - "5a-reductase inhibitors (5a-RIs), while improving urinary symptoms in patients with benign prostatic hyperplasia (BPH) and possible hair loss prevention, produces significant adverse effects in some individuals including loss of libido, erectile dysfunction (ED), ejaculatory dysfunction and potential depression" - Note:  That goes back and forth.  One study claimed that finasteride improved sex after after six months of taking it.  Regarding gynaecomastia, if you're taking low dose letrozole to increase testosterone and to prevent aromatization it many also help prevent gynaecomastia.
