Recent Longevity News for the week ending 1/27/16
Brain levels of vitamin B12 decrease with age and are prematurely low in people with autism and schizophrenia - Science Daily, 1/23/16 - "Vitamin B12 levels in the brain are significantly decreased in the elderly and are much lower in individuals with autism or schizophrenia, as compared to their peers at similar ages ... healthy elderly people in the age range of 61-80 have about three times lower levels of total brain B12 than younger age groups, which is a result of normal aging" - See vitamin B12 at Amazon.com.
New study shows aged garlic extract can reduce dangerous plaque buildup in arteries - Science Daily, 1/21/16 - "the participants were given either a placebo or a dose of 2,400 milligrams of Aged Garlic Extract every day. A follow-up screening conducted a year after the initial screening found those who had taken Aged Garlic Extract had slowed total plaque accumulation by 80%, reduced soft plaque and demonstrated regression (less plaque on follow-up) for low-attenuation plaque" - See garlic supplements at Amazon.com.
B12 deficiency a concern for long-term care - Science Daily, 1/19/16 - "A high proportion of older adults entering long-term care homes in Ontario are B12 deficient, with more developing deficiencies over the course of their first year in residence ... Untreated B12 deficiency will eventually lead to anemia and neurologic complications such as unsteady gait and paralysis. Low levels of the vitamin have been found to be associated with depression and dementia, increased confusion, lethargy and even osteoporosis" - See vitamin B12 at Amazon.com.
Abstracts from this week:
Fish, Long-Chain n-3 PUFA and Incidence of Elevated Blood Pressure: A Meta-Analysis of Prospective Cohort Studies - Nutrients. 2016 Jan 21;8(1) - "elevated blood pressure (EBP) ... Circulating LC n-3 PUFA as biomarker was inversely associated with incidence of EBP (SRR: 0.67; 95% CI: 0.55, 0.83), especially docosahexaenoic acid (SRR: 0.64; 95% CI: 0.45, 0.88), whereas no significant association was found for dietary intake (SRR: 0.80; 95% CI: 0.58, 1.10). The present finding suggests that increased intake of docosahexaenoic acid to improve its circulating levels may benefit primary prevention of EBP" - See Jarrow Max DHA at Amazon.com.

Vinegar treatment prevents the development of murine experimental colitis via inhibition of inflammation and apoptosis - J Agric Food Chem. 2016 Jan 21 - "This study investigated the preventive effects of vinegar and acetic acid (the active component of vinegar) on ulcerative colitis (UC) in mice. Vinegar (5% v/v) or acetic acid (0.3% w/v) treatment significantly reduced the disease activity index and histopathological scores, attenuated body weight loss and shortened the colon length in a murine experimental colitis model induced by dextran sulfate sodium (DSS) ... Surprisingly, pretreatment with vinegar for 28 days before DSS induction increased levels of the commensal lactic acid-producing or acetic acid-producing bacteria, including Lactobacillus, Bifidobacteria and Enterococcus faecalis, whereas decreased Escherichia coli levels were found in the feces of mice. These results suggest that vinegar supplement might provide a new dietary strategy for the prevention of UC" - See apple cider vinegar at Amazon.com.
Influence of Topical, Systemic and Combined Application of Antioxidants on the Barrier Properties of the Human Skin - Skin Pharmacol Physiol. 2016 Jan 23 - "The formation of free radicals in human skin by solar ultraviolet radiation is considered to be the main reason for extrinsic skin aging. The antioxidants in human tissue represent an efficient protection system against the destructive action of these reactive free radicals ... The study included 5 groups of 15 volunteers each, who were treated for 2 months with antioxidant-containing or placebo tablets, creams or a combination of antioxidant-containing tablets and cream ... The verum cream had a positive influence on epidermal thickness, elasticity and skin moisture, but the verum tablets improved the epidermal thickness only. The combined application of verum tablets and creams led to a significant improvement of all investigated skin parameters, whereas the application of placebo tablets or cream did not influence any parameters" - See OZ Naturals- THE BEST Vitamin C Serum For Your Face Contains Clinical Strength 20% Vitamin C + Hyaluronic Acid Anti Wrinkle Anti Aging Serum For A Radiant & More Youthful Glow!, Protein Essentials Hydrolyzed Collagen Protein Powder with Peptan® (16oz) at Amazon.com and Sunkist Grower Select Blueberry Capsules, 500 mg, 90 Count Bottle.

Free Thyroxine and Functional Mobility, Fitness, and Fatigue in Euthyroid Older Men and Women in the Baltimore Longitudinal Study of Aging - J Gerontol A Biol Sci Med Sci. 2016 Jan 20 - "Adjusting for sex, age, race, height, weight, exercise and smoking, reported walking ability, usual and rapid gait speed, 400-m time, fatigability, and reported energy level were less favorable with increasing FT4 (p = .013 to <.001). In sex-strata, similar associations were observed except for walking ability in men and energy level in women. Categorical analyses revealed that persons with low FT4 exhibited better functional mobility, fitness, and reported energy than persons with intermediate or high levels (p < .05 for all). Persons with high-normal versus medium FT4 had slower usual and rapid gait speed (p < .05) only"
Dietary anthocyanin intake and age-related decline in lung function: longitudinal findings from the VA Normative Aging Study - Am J Clin Nutr. 2016 Jan 20 - "Strong inverse associations were found between anthocyanin intake and age-related decline in lung function. Independent of dietary and nondietary risk factors, slower rates of FEV1 and FVC decline by 23.6 (95% CI: 16.6, 30.7) and 37.3 (95% CI: 27.8, 46.8) mL/y, respectively, were observed in participants in the fourth quartile of intake compared with participants in the first quartile (P-trend < 0.0001). The protective associations observed for anthocyanin intake were present in both current/former and never smokers. Compared with no or very low intakes, an intake of ≥2 servings of anthocyanin-rich blueberries/wk was associated with slower decline in FEV1 and FVC by 22.5 (95% CI: 10.8, 34.2) and 37.9 (95% CI: 22.1, 53.7) mL/y, respectively. To a lesser extent, higher flavan-3-ol intake was also associated with slower lung function decline" - See blueberry extract at Amazon.com and grape seed extract at Amazon.com.

Epidemiological and Mendelian randomisation studies of dihydrotestosterone and estradiol, and leucocyte telomere length in men - J Clin Endocrinol Metab. 2016 Jan 20 - "Advancing age is accompanied by accumulation of ill-health and shortening of chromosomal telomeres signifying biological ageing. Testosterone (T) is metabolised to dihydrotestosterone (DHT) by 5|ga-reductase (SRD5A2) and to estradiol (E2) by aromatase (CYP19A1). Telomerase preserves telomeres, and T and E2 regulate telomerase expression and activity in vitro ... leucocyte telomere length (LTL) ... After adjustment for age, DHT and E2 were positively correlated with LTL"
Coffee induces vascular endothelial growth factor (VEGF) expression in human neuroblastama SH-SY5Y cells - Nutr Neurosci. 2016 Jan 20 - "Our results suggest that daily consumption of coffee may induce VEGF expression in neuronal cells. This might be related to protective effect of coffee on neural disorders such as Alzheimer's disease and Parkinson's disease"

Taurine Supplementation Lowers Blood Pressure and Improves Vascular Function in Prehypertension: Randomized, Double-Blind, Placebo-Controlled Study - Hypertension. 2016 Jan 18 - "We randomly assigned 120 eligible prehypertensive individuals to receive either taurine supplementation (1.6 g per day) or a placebo for 12 weeks. Taurine supplementation significantly decreased the clinic and 24-hour ambulatory BPs, especially in those with high-normal BP. Mean clinic systolic BP reduction for taurine/placebo was 7.2/2.6 mm Hg, and diastolic BP was 4.7/1.3 mm Hg. Mean ambulatory systolic BP reduction for taurine/placebo was 3.8/0.3 mm Hg, and diastolic BP was 3.5/0.6 mm Hg.
