Periodontitis Linked to HPV-Positive Oral Tumors - Medscape, 6/19/12 - "After adjustment for age at diagnosis, sex, and smoking status, each millimeter of alveolar bone loss was associated with a 2.6-times increased odds of an HPV-positive tumor (odds ratio [OR], 2.61; 95% confidence interval, 1.58 to 4.30). The strength of this association was greater for patients with oropharyngeal lesions (OR, 11.70) than for those with oral cavity tumors (OR, 2.32) and laryngeal squamous cell carcinoma (OR, 3.89)"

Natural antioxidant can protect against cardiovascular disease - Science Daily, 6/16/12 - "The enzyme -- glutathione peroxidase, or GPx3 -- is a natural antioxidant that helps protect organisms from oxidant injury and helps the body naturally repair itself. Researchers have found that patients with high levels of good cholesterol, the GPx3 enzyme does not make a significant difference. However, those patients with low levels of good cholesterol, the GPx3 enzyme could potentially be a big benefit ... The new research, published June 16 by PLoS One, supports the view that natural antioxidants may offer the human body profound benefits ... people with high levels of the GPx3 enzyme and low levels of good cholesterol were six times less likely to develop cardiovascular disease than people with low levels of both"

• Glutathione supplements pills benefit and side effects - raysahelian.com -  "This antioxidant, made from the combination of three amino acids cysteine, glutamate, and glycine, forms part of the powerful natural antioxidant glutathione peroxidase which is found in our cells ... Supplements that help make glutathione ... Acetylcysteine ... ALA ... Pycnogenol ... The frequent use of acetaminophen (Tylenol) depletes glutathione peroxidase levels" - See n-acetyl cysteine at Amazon.com.

Vitamin B12 Deficiency With Metformin Linked to Neuropathy - Medscape, 6/15/12 - "In patients with type 2 diabetes taking metformin, vitamin B12 deficiency is associated with higher levels of peripheral neuropathy ... Chronic metformin use has been previously shown to be associated with vitamin B12 deficiency. Peripheral neuropathy is typically diagnosed as diabetic neuropathy, but this can also be a symptom of vitamin B12 deficiency ... I think we must be careful about older patients and patients who take metformin for a long time. We must measure levels of vitamin B12. We don't change therapies [at our institution], but we treat deficiencies with B12 supplements" - See vitamin B12 at Amazon.com.

BPA exposure effects may last for generations - Science Daily, 6/15/12 - "Since exposure to BPA changes social interactions in mice at a dose within the reported human levels, it is possible that this compound has trans-generational actions on human behavior. If we banned BPA tomorrow, pulled all products with BPA in them, and cleaned up all landfills tomorrow it is possible, if the mice data generalize to humans, that we will still have effects of this compound for many generations ... female mice received chow with or without BPA before mating and throughout gestation. Plasma levels of BPA in supplemented female mice were in a range similar to those measured in humans. Juveniles in the first generation exposed to BPA in utero displayed fewer social interactions as compared with control mice. The changes in genes were most dramatic in the first generation (the offspring of the mice that were exposed to BPA in utero), but some of these gene changes persisted into the fourth generation"

Vitamin D with calcium shown to reduce mortality in elderly - Science Daily, 6/15/12 - "The findings from the study found that the reduced mortality was not due to a lower number of fractures, but represents a beneficial effect beyond the reduced fracture risk ... This is the largest study ever performed on effects of calcium and vitamin D on mortality ... Our results showed reduced mortality in elderly patients using vitamin D supplements in combination with calcium, but these results were not found in patients on vitamin D alone ... pooled data from eight randomized controlled trials with more than 1,000 participants each. The patient data set was composed of nearly 90 percent women, with a median age of 70 years. During the three-year study, death was reduced by 9 percent in those treated with vitamin D with calcium ... Some studies have suggested calcium (with or without vitamin D) supplements can have adverse effects on cardiovascular health ... Although our study does not rule out such effects, we found that calcium with vitamin D supplementation to elderly participants is overall not harmful to survival, and may have beneficial effects on general health" - See vitamin D at Amazon.com.

Omega-3 Heart Trial Fails the Test - vitalchoice.com, 6/15/12 - "Authors acknowledge their study's limitations and flaws ..."

Virtual colonoscopy without laxative equals standard OC in identifying clinically significant polyps - Science Daily, 6/14/12 - "Computed tomographic colonography (CTC), also known as virtual colonoscopy, administered without laxatives is as accurate as conventional colonoscopy in detecting clinically significant, potentially cancerous polyps ... patients do not have to go through bowel cleansing before the exam, but instead begin a low fiber diet two days before the test. They also ingest a tagging agent the day before the exam, which mixes with residual material in the colon and can then be identified and removed digitally when radiologists interpret the scans ... laxative-free CTC exams detected clinically significant polyps 10 mm or larger with 91 percent accuracy compared to OC exams, which were 95 percent accurate. Statistically, there is no difference between these two number"

Bodybuilding myth debunked: Growth-promoting hormones don't stimulate strength - Science Daily, 6/14/12 - "anabolic hormones -- long thought to be essential for building a muscular frame -- do not influence muscle protein synthesis, the process that leads to bigger muscles ... In the first study, researchers examined the responses of both male and female participants to intense leg exercise. Despite a 45-fold difference in testosterone increase, men and women were able to make new muscle protein at exactly the same rate ... In the second study ... The men experienced gains in muscle mass that ranged from virtually nothing to more than 12 pounds, yet their levels of testosterone and growth hormone after exercise showed no relationship to muscle growth or strength gain ... Surprisingly, the researchers noted that cortisol -- considered to have the opposite effect of anabolic hormones because it reduces protein synthesis and breaks down tissue -- was related to the gain in muscle mass" - Note:  That may be true about cortisol but looking at it another way, cortisol could be an indicator of how much you're working out.  Actually and increase in muscle due to an increase in weight lifting with a corresponding increase in cortisol due to the increased weight lifting is what I'd expect.

Link between metabolic disorders and Alzheimer's disease examined - Science Daily, 6/14/12 - "individuals with T2D have a nearly twofold higher risk of AD than nondiabetic individuals"

Eat Breakfast, Cut Diabetes and Obesity Risk - WebMD, 6/14/12 - "Compared to people who ate breakfast three or fewer times per week, they were: ... 34% less likely to develop type 2 diabetes ... 43% less likely to become obese ... 40% less likely to develop fat around the tummy (abdominal obesity)"

N-Acetylcysteine Mucolysis in the Management of COPD : Abstract and Introduction - Medscape, 6/14/12 - "NAC may exert its mucolytic and mucoregulatory action via several mechanisms (Figure 3). First, it works through depolymerization of the mucin glycoprotein oligomers by hydrolyzing the disulfide bonds that link the mucin monomers. This is possible because of the presence of free thiols (sulfhydryl groups). Therefore, NAC decreases the sputum viscosity in vitro [Sheffner, 1963; Davis et al. 1975] and acts as a mucolytic. Second, it plays a mucoregulatory role as it can decrease sputum hypersecretion in experimental rat models [Rogers et al. 1989]. Moreover, it has been demonstrated to inhibit the mucus secretory cell hyperplasia and enhanced expression of the MUC5AC gene in bleomycin-induced lung fibrosis in rats [Mata et al. 2003]" - See n-acetyl cysteine at Amazon.com.

Folic acid intake during early pregnancy associated with reduced risk of autism in offspring - Science Daily, 6/14/12 - "The study found that women who each day consumed the recommended amount of folic acid (600 micrograms, or .6 milligrams) during the first month of pregnancy experienced a reduced risk of having a child with autism spectrum disorder, specifically when the mother and/or her child had a specific genetic variant (MTHFR 677 C>T) associated with less efficient folate metabolism" - See folic acid products at Amazon.com.

Obesity, depression found to be root causes of daytime sleepiness - Science Daily, 6/13/12 - "Three studies being presented June 13 at sleep 2012 conclude that obesity and depression are the two main culprits making us excessively sleepy while awake ... Insufficient sleep and obstructive sleep apnea also play a role; both have been linked to high blood pressure, heart disease, stroke, depression, diabetes, obesity and accidents"

Early gut bacteria regulate happiness - Science Daily, 6/12/12 - "UCC scientists have shown that brain levels of serotonin, the 'happy hormone' are regulated by the amount of bacteria in the gut during early life ... normal adult brain function depends on the presence of gut microbes during development. Serotonin, the major chemical involved in the regulation of mood and emotion, is altered in times of stress, anxiety and depression and most clinically effective antidepressant drugs work by targeting this neurochemical ... Scientists at the Alimentary Pharmabiotic Centre in UCC used a germ-free mouse model to show that the absence of bacteria during early life significantly affected serotonin concentrations in the brain in adulthood ... Finally, when the scientists colonized the animals with bacteria prior to adulthood, they found that many of the central nervous system changes, especially those related to serotonin, could not be reversed indicating a permanent imprinting of the effects of absence of gut flora on brain function" - See probiotic products at Amazon.com.

A Double-Blind Randomized Controlled Trial of N-Acetylcysteine in Cannabis-Dependent Adolescents - Am J Psychiatry. 2012 Jun 15 - "Participants receiving NAC had more than twice the odds, compared with those receiving placebo, of having negative urine cannabinoid test results during treatment (odds ratio=2.4, 95% CI=1.1-5.2) ... Findings support NAC as a pharmacotherapy to complement psychosocial treatment for cannabis dependence in adolescents" - See n-acetyl cysteine at Amazon.com.

Lower serum vitamin D levels are associated with a higher relapse risk in multiple sclerosis - Neurology. 2012 Jun 13 - "There is increasing evidence that vitamin D can be protective against the development of multiple sclerosis (MS), but it may also be beneficial for the clinical course of the disease ... Exacerbation risk decreased significantly with higher serum vitamin D levels: respective relative exacerbation rates for the medium and high-level category as compared to the low-level category were 0.7 and 0.5 (p value for trend: p = 0.007). The association between 25-OH-D concentrations and exacerbation rate was log linear without a threshold. With each doubling of the serum 25-OH-D concentration the exacerbation rate decreased by 27% (95% confidence interval 8%-42%, p = 0.008)" - See vitamin D at Amazon.com.

Coffee consumption and prostate cancer risk: further evidence for inverse relationship - Nutr J. 2012 Jun 13;11(1):42 - "We conducted a prospective cohort study of 6017 men who were enrolled in the Collaborative cohort study in the UK between 1970 and 1973 and followed up to 31st December 2007 ... Higher coffee consumption was inversely associated with risk of high grade but not with overall risk of PC. Men consuming 3 or more cups of coffee per day experienced 55% lower risk of high Gleason grade disease compared with non-coffee drinkers in aanalyses adjusted for age and social class (HR 0.45, 95% CI 0.23-0.90, p value for trend 0.01). This association changed a little after additional adjustment for Body Mass Index, smoking, cholesterol level, systolic blood pressure, tea intake and alcohol consumption"

Coffee consumption and risk of colorectal cancer: a meta-analysis of observational studies - Public Health Nutr. 2012 Jun 14:1-12 - "we performed a meta-analysis based on both case-control and cohort studies ... Twenty-five case-control (15 522 cases) and sixteen cohort studies (10 443 cases) were included in the meta-analysis. Comparing the highest v. the lowest/non category of coffee consumption, the combined results from case-control studies showed a significant relationship with colorectal cancer (OR = 0.85, 95 % CI 0.75, 0.97) and colon cancer (OR = 0.79, 95 % CI 0.67, 0.95), but not rectal cancer (OR = 0.95, 95 % CI 0.79, 1.15). For cohort studies, there was a slight suggestion of an inverse association with colorectal cancer (relative ratio = 0.94; 95 % CI 0.88, 1.01) and colon cancer (OR = 0.93, 95 % CI 0.86, 1.01), rather than rectal cancer (OR = 0.98, 95 % CI 0.88, 1.09). In subgroup analyses using case-control studies, significant inverse associations were found in females for colorectal cancer and in Europe for colorectal and colon cancer, while the subgroup analyses of cohort studies found that coffee drinks substantially decreased risk of colon cancer only in Asian women"

Caffeinated and decaffeinated coffee and tea intakes and risk of colorectal cancer in a large prospective study - Am J Clin Nutr. 2012 Jun 13 - "Compared with nondrinkers, drinkers of 4-5 cups coffee/d (HR: 0.85; 95% CI: 0.75, 0.96) and ≥6 cups coffee/d (HR: 0.74; 95% CI: 0.61, 0.89; P-trend < 0.001) had a lower risk of colon cancer, particularly of proximal tumors (HR for ≥6 cups/d: 0.62; 95% CI: 0.49, 0.81; P-trend < 0.0001). Results were similar to those overall for drinkers of predominantly caffeinated coffee. Although individual HRs were not significant, there was a significant P-trend for both colon and rectal cancers for people who drank predominantly decaffeinated coffee. No associations were observed for tea"

Vitamin K, vertebral fractures, vascular calcifications and mortality: Vitamin K Italian (VIKI) dialysis study - J Bone Miner Res. 2012 Jun 12 - "Vitamin K1 deficiency was the strongest predictor of vertebral fractures (OR 2.94 95%CI 1.38-6.26). MK4 deficiency was a predictor of aortic calcification (OR 2.82 95%CI 1.14-7.01), whereas MK5 deficiency actually protected against it (OR 0.38 95%CI 0.15-0.95). MK7 deficiency was a predictor of iliac calcification (OR 1.64 95%CI 1.03-2.60). The presence of vertebral fractures was also a predictor of vascular calcifications (OR 1.76 95%CI 1.00-3.08). Increased alkaline phosphatase and C reactive protein (CRP), age, cerebrovascular events were predictors of mortality. Our study suggests that the vitamin K system may be important for preserving bone mass and avoiding vascular calcification in hemodialysis patients, pointing out a possible role of vitamin K in bone and vascular health" - See vitamin K products at iHerb.

The effect of vitamin D and frailty on mortality among non-institutionalized US older adults - Eur J Clin Nutr. 2012 Jun 13 - "Serum 25(OH)D concentrations were lowest in participants with frailty, intermediate in participants with pre-frailty and highest in participants without frailty. The odds of frailty in the lowest quartile of serum 25(OH)D was 1.94 times the odds in the highest quartile (95% confidence interval (CI): 1.09-3.44). Mortality was positively associated with frailty, with the risk among participants who were frail and had low serum 25(OH)D being significantly higher than those who were not frail and who had high concentrations of serum 25(OH)D (hazards ratio 2.98; 95% CI: 2.01-4.42)" - See vitamin D at Amazon.com.

Diabetes, Metformin, and Breast Cancer in Postmenopausal Women - J Clin Oncol. 2012 Jun 11 - "assessed associations among diabetes, metformin use, and breast cancer in postmenopausal women participating in Women's Health Initiative clinical trials ... observed over a mean of 11.8 years ... Women with diabetes receiving medications other than metformin had a slightly higher incidence of breast cancer (hazard ratio [HR], 1.16; 95% CI, 0.93 to 1.45), and women with diabetes who were given metformin had lower breast cancer incidence (HR, 0.75; 95% CI, 0.57 to 0.99). The association was observed for cancers positive for both estrogen receptor and progesterone receptor and those that were negative for human epidermal growth factor receptor 2 ... Metformin use in postmenopausal women with diabetes was associated with lower incidence of invasive breast cancer" - See metformin at The Antiaging Store.

The effect of pioglitazone treatment on 15-epi-lipoxin A(4) levels in patients with type 2 diabetes - Atherosclerosis. 2012 May 7 - "Arachidonic acid-derived eicosanoids (lipoxins and 15-epilipoxins) have a major role in resolution of inflammation. 15-epi-lipoxin A(4) (15-epi-LXA(4)) is a lipid mediator with strong anti-inflammatory and inflammation-resolving effects ... PIO 15 increased plasma 15-epi-LXA(4) levels (0.63 +/- 0.06-1.05 +/- 0.08 ng/mL, p < 0.01) and adiponectin levels (6.4 +/- 0.3-10.1 +/- 0.7 μg/mL, p < 0.001) and decreased fasting plasma glucose (125 +/- 8-106 +/- 9 mg/dL, p < 0.05), free fatty acids (FFA) (414 +/- 46-320 +/- 38 μmol/l, p < 0.05) and HOMA-IR (5.3 +/- 0.4 to 4.0 +/- 0.4, p < 0.05). Body weight (Δ = 0.2 kg) and HbA1c (7.4 +/- 0.2-7.1 +/- 0.2%) did not change significantly. PIO 30 treated patients had similar increase in plasma 15-epi-LXA(4) (0.64 +/- 0.10-1.08 +/- 0.09 ng/mL, p < 0.01), and decrease in plasma FFA (423 +/- 42-317 +/- 40 μmol/l, p < 0.05) despite a greater increase in plasma adiponectin (6.5 +/- 0.4-15.5 +/- 0.7 ug/mL, p < 0.001) and a greater reduction in HbA1c (8.7 +/- 0.5-7.4 +/- 0.3%, p < 0.01), FPG (159 +/- 16-120 +/- 10 mg/dL, p < 0.01), and HOMA-IR (6.6 +/- 0.8-4.4 +/- 0.4, p < 0.005).

Delayed paternal age of reproduction in humans is associated with longer telomeres across two generations of descendants - Proc Natl Acad Sci U S A. 2012 Jun 11 - "Telomeres are repeating DNA sequences at the ends of chromosomes that protect and buffer genes from nucleotide loss as cells divide. Telomere length (TL) shortens with age in most proliferating tissues, limiting cell division and thereby contributing to senescence. However, TL increases with age in sperm, and, correspondingly, offspring of older fathers inherit longer telomeres. Using data and samples from a longitudinal study from the Philippines, we first replicate the finding that paternal age at birth is associated with longer TL in offspring (n = 2,023, P = 1.84 × 10(-6)). We then show that this association of paternal age with offspring TL is cumulative across multiple generations: in this sample, grandchildren of older paternal grandfathers at the birth of fathers have longer telomeres (n = 234, P = 0.038), independent of, and additive to, the association of their father's age at birth with TL. The lengthening of telomeres predicted by each year that the father's or grandfather's reproduction are delayed is equal to the yearly shortening of TL seen in middle-age to elderly women in this sample, pointing to potentially important impacts on health and the pace of senescent decline in tissues and systems that are cell-replication dependent"

• A diet rich in slowly digested carbs reduces markers of inflammation in overweight and obese adults - Science Daily, 1/11/12 - "Among overweight and obese adults, a diet rich in slowly digested carbohydrates, such as whole grains, legumes and other high-fiber foods, significantly reduces markers of inflammation associated with chronic disease ... a low-glycemic-load diet reduced a biomarker of inflammation called C-reactive protein by about 22 percent ... C-reactive protein is associated with an increased risk for many cancers as well as cardiovascular disease ... a low-glycemic-load diet modestly increased -- by about 5 percent -- blood levels of a protein hormone called adiponectin ... a low-glycemic-load diet modestly increased -- by about 5 percent -- blood levels of a protein hormone called adiponectin. This hormone plays a key role in protecting against several cancers, including breast cancer, as well as metabolic disorders such as type-2 diabetes, nonalcoholic fatty liver disease and hardening of the arteries"
• Low-Dose Dietary Resveratrol Has Differential Effects on Colorectal Tumorigenesis in Adiponectin Knockout and Wild-Type Mice - Nutr Cancer. 2011 Sep 29 - "Obesity is associated with a decrease in the antiinflammatory hormone, adiponectin, and increases in the circulating concentrations of multiple proinflammatory cytokines. These changes contribute to colon tumorigenesis. Resveratrol increases adiponectin production in adipocytes and attenuates the development of colon cancer. Thus, we hypothesized that adiponectin is an integral component of the mechanism by which resveratrol antagonizes colorectal tumorigenesis. To investigate this, we induced tumorigenesis in adiponectin knockout (KO) and wild-type (Wt) C57BL/6 mice through combined azoxymethane and dextran sodium sulfate treatment during which mice were fed a high-fat, lard-based diet, or the same diet containing 20 mg/kg resveratrol. After 14 wk on diet, Wt mice gained more weight and, on a percentage basis, had higher fat mass and lower lean mass than KO mice. Resveratrol tended to attenuate this response in male Wt mice. Resveratrol also tended to reduce aberrant crypt foci development and decrease circulating interleukin 6 and insulin concentrations in male but not female Wt mice. Taken together, resveratrol improved overall health of obese Wt but not KO mice as hypothesized with a differential sex response" - See resveratrol products at Amazon.com.
• Isomer-specific effects of conjugated linoleic acid on blood pressure, adipocyte size and function - Br J Nutr. 2011 Sep 23:1-9 - "Consumption of conjugated linoleic acid (CLA) has been shown to modulate cytokine release from adipocytes and positively influence blood pressure in younger rats, but its physiological actions in older models with established hypertension and isomer-specific effects on adipocyte size remain to be determined. Therefore, we investigated the effects of CLA isomers on adipocyte size in relation to blood pressure and adipokine production by hypertrophic adipocytes in older fa/fa Zucker rats with established hypertension. fa/fa Zucker rats were fed with cis(c)9, trans(t)11-CLA or t10, c12-CLA isomers for 8 weeks and compared with lean and obese rats fed with the control diet. Blood pressure and adipocyte size were subsequently measured. Collagenase-isolated adipocytes were size-separated and angiotensinogen and adiponectin protein levels quantified by Western blotting. The t10, c12-CLA group had reduced blood pressure, fewer large adipocytes and increased serum adiponectin. Angiotensinogen was present at higher levels in the large adipocytes, whereas the converse was observed for adiponectin. The beneficial effects of the t10, c12-CLA isomer on blood pressure and adipocyte size in vivo may be due to its ability to reduce the number of large adipocytes, which alters the levels of vasoactive molecules secreted from adipose tissue" - See conjugated linoleic acid at Amazon.com.
• Harvard study supports coffee’s anti-diabetes potential - Nutra USA, 9/21/11 - "Five cups of coffee per day for two months were associated with significant metabolic benefits and live function ... the metabolic benefits were more pronounced in caffeinated coffee, a result that supports the hypothesis that caffeine is responsible for some of the apparent benefits ... Coffee is also a rich source of polyphenols ... one cup of the stuff could provide 350 milligrams of phenolics ... Of these, the most abundant compounds in coffee are chlorogenic acids, making up to 12 per cent of the green coffee bean. The most abundant of these compounds is caffeic acid ... recruited 45 healthy, overweight coffee drinking 40 year olds ... volunteers were asked to drink five cups of coffee per day of instant caffeinated coffee, decaffeinated coffee, or water for eight weeks ... coffee consumption was associated with a 60% reduction in blood levels of a compound called interleukin-6, which can promote inflammation, compared with the water group ...

• Trans-10, cis-12-conjugated linoleic acid reduces the hepatic triacylglycerol content and the leptin mRNA level in adipose tissue in obese Zucker fa/fa rats - Br J Nutr. 2009 Mar 19:1-13 - "Conjugated linoleic acid (CLA) isomers have been reported to reduce body weight and beneficially affect glucose metabolism in animals, but the results are inconsistent and seem to depend on animal model and type of CLA isomer. In the present study, feeding male Zucker fa/fa rats diets supplemented with 1 % trans-10, cis-12-CLA for 10 d reduced the liver TAG content without improving the overall adiposity, and enhanced hepatic mitochondrial and peroxisomal beta-oxidation ... The present results suggest that dietary supplementation with trans-10, cis-12-CLA may increase the catabolism of lipids in liver and adipose tissue. Moreover, we provide new data suggesting that trans-10, cis-12-CLA modulates the expression of resistin and adiponectin inversely in adipose tissue. Hence, the present results suggest that trans-10, cis-12-CLA may have some beneficial effects on lipid metabolism and adiposity but possibly reduces insulin sensitivity" - See CLA products at iHerb.

• Red Wine's Resveratrol May Help Battle Obesity - Science Daily, 6/16/08 - "resveratrol inhibited the pre-fat cells from increasing and prevented them from converting into mature fat cells. Also, resveratrol hindered fat storage. Most interesting, according to Fischer-Posovszky, was that resveratrol reduced production of certain cytokines (interleukins 6 and 8), substances that may be linked to the development of obesity-related disorders, such as diabetes and clogged coronary arteries. Also, resveratrol stimulated formation of a protein known to decrease the risk of heart attack. Obesity decreases this substance, called adiponectin" - [WebMD] - See resveratrol products at Amazon.com.

• Adiponectin elevation by telmisartan ameliorates ISCHEMIC MYOCARDIUM IN Zucker Diabetic Fatty rats with metabolic syndrome - Diabetes Obes Metab. 2011 Nov 3 - "myocardial ischemia/reperfusion (I/R) injury ... Telmisartan reduced the extension of the infarct size in a dose-dependent fashion and decreased the levels of plasma troponin I, a specific marker of myocardial damage. Telmisartan also caused a dose-dependent increase in adiponectin both in plasma and cardiac tissue of infarcted ZDF rats. These levels were minimally increased (p<0.05 vs vehicle) by telmisartan 7 mg/kg/day and reached the maximum values with the highest dose of 12 mg/kg/day (p<0.01 vs vehicle). In contrast, within the infarcted tissue telmisartan decreased the expression of markers of inflammation such as the transcription factor NF-κB, the toll-like receptors TLR2 and TLR4 as well as TNF-α cytokine. Nitrosative stress was maximal in vehicle-treated infarcted hearts as evidenced by increased expression of iNOS, which was almost abolished after treatement with telmisartan. Conclusions: Treatment of ZDF rats for three weeks with telmisartan, a dual angiotensin II receptor antagonist and partial PPAR-γ receptor agonist, resulted in a significant reduction of myocardial damage induced by I/R and was assocciated with increased adiponectin and a decrease in inflammatory markers"

When the researchers introduced adiponectin into cells, they found that the hormone triggers the conversion of ceramides from a destructive force into one that helps cells survive and inhibits cell death ... the new findings have implications for the treatment of numerous diseases including diabetes and cancer ... we can protect those cells from cell death with adiponectin ... Adiponectin, which Dr. Scherer discovered in 1994, not only controls sensitivity to insulin but also is known to play an integral role in metabolism and obesity ... As a person accumulates more fat, however, adiponectin levels decline. Once adiponectin levels start dropping, the body begins storing fat in dangerous places such as the heart, liver and muscle tissues -- where it can cause inflammation and pave the way for heart disease ... adiponectin is very important and is probably a key manipulator of lipid levels"

• Adiponectin and adiponectin receptor in relation to colorectal cancer progression - Int J Cancer. 2010 Dec 15;127(12):2758-67 - "Although obesity is a risk factor for colorectal cancer, the underlying mechanism is not clear. Adiponectin is an adipokine that binds to 2 types of receptors, AdipoR1 and AdipoR2. The plasma concentrations of adiponectin are reduced in obese individuals and adiponectin has been reported to have anticarcinogenic properties. Furthermore, AdipoR1 and AdipoR2 have been reported to be expressed in several malignancies ... AdipoR1 and AdipoR2 immunostaining was detected in 72 and 68% of human colorectal cancer tissue, respectively. AdipoR1 and AdipoR2 expression levels were inversely related to T stage. The lowest AdipoR1 and AdipoR2 expression were detected in poorly differentiated adenocarcinoma. RT-PCR also showed the expression of AdipoR1 and AdipoR2 in HCT116 and SW620. MTT assay and TUNEL assay demonstrated the tendency of growth inhibition and apoptosis induction in both cell lines after full-length adiponectin treatment although statistically insignificant. Microarray analysis revealed several gene responses to full-length adiponectin, including upregulation of ENDOGL1 and MT1G. In conclusion, AdipoR1 and AdipoR2 may be intimately related to the progression of colorectal cancer"

• Hypoadiponectinemia is strongly associated with metabolic syndrome in korean type 2 diabetes patients - J Am Coll Nutr. 2010 Jun;29(3):171-8 - "Our findings show that hypoadiponectinemia is strongly associated with MetS in type 2 DM patients. Dietary intake may be indirectly associated with adiponectin levels through factors such as BMI, waist circumference, insulin, homeostasis model assessment of insulin resistance (HOMA-IR), triglyceride, HDL-cholesterol, and blood pressure. Therefore, our results suggest that manipulation of the level of adiponectin may prevent MetS and reduce the risk of cardiovascular disease in type 2 DM patients"
• Adiposity and Insulin Resistance Correlate with Telomere Length in Middle-aged Arabs: The Influence of Circulating Adiponectin - Eur J Endocrinol. 2010 Aug - "Studies in obesity have implicated adipocytokines in the development of insulin resistance, which in turn may lead to accelerated aging ... HOMA-IR was the most significant predictor for TL in males, explaining 35% of the variance (p = 0.01). In females, adiponectin, accounted for 28% of the variance in TL (p = 0.01). Conclusion: Obesity and insulin resistance are associated with chromosomal TL among adult Arabs. Evidence of causal relations needs further investigation. The positive association of adiponectin to TL has clinical implications as to the possible protective effects of this hormone from accelerated aging" - Note:  HOMA-IR = (glucose x insulin)/405 for glucose in mass units (US units) mg/dL.

Strong inverse associations with adiponectin were observed for BMI (-10.72%; 95% CI: -13.78, -7.55), total (-6.89%: 95% CI: -10.34, -3.30; P < 0.05), and central fat mass (-12.50%; 95% CI: -15.82, -9.05; P < 0.05); these relationships were significant both when twins were analyzed as individuals and when characteristics were contrasted within-twin pairs, suggesting a direct effect. We observed modest associations between dietary factors and adiponectin in female twins, independent of adiposity, and report strong inverse associations with body composition. These data reinforce the importance of weight maintenance and increasing consumption of diets rich in plant-based foods to prevent CVD and type 2 diabetes"

• Anti-inflammatory and cardioprotective effects of n-3 polyunsaturated fatty acids and plant sterols in hyperlipidemic individuals - Atherosclerosis. 2008 Sep 27 - "The combination of n-3 PUFA and plant sterols reduced several inflammatory markers. High sensitivity C-reactive protein (hs-CRP) was reduced by 39% (P=0.009), tumor necrosis factor-alpha (TNF-alpha) by 10% (P=0.02), interleukin-6 (IL-6) by 10.7% (P=0.009), leukotriene B(4) (LTB(4)) by 29.5% (P=0.01) and adiponectin was increased by 29.5% (P=0.05). Overall cardiovascular risk was reduced by 22.6% (P=0.006) in the combination group. CONCLUSION: We have demonstrated, for the first time that dietary intervention with n-3 PUFA and plant sterols reduces systemic inflammation in hyperlipidemic individuals. Furthermore, our results suggest that reducing inflammation provides a potential mechanism by which the combination of n-3 PUFA and plant sterols are cardioprotective" - See Mega Twin EPA at Amazon.com and Jarrow Max DHA at Amazon.com.

In vitro, although the protein level of adiponectin was not significantly elevated, the mRNA expression of adiponectin was elevated 1.5-fold by telmisartan in 3T3-L1 adipocytes. Our findings suggest that telmisartan may have beneficial effects in type 2 diabetes beyond its antihypertensive effect" - I've been saying that telmisartan should be the first line treatment for hypertension for some time now if natural methods such as coenzyme Q10 don't work.
• Acarbose Treatment Increases Serum Total Adiponectin Levels in Patients with Type 2 Diabetes - Endocr J. 2008 May 15 - "Treatment with acarbose and pioglitazone decreased HbA1c values by 0.49 % and 0.63 %, respectively. Pioglitazone, as expected, increased serum levels of total adiponectin by 2.1 fold and its high molecular weight isoform by 3.6 fold.

• Effect of green tea on kidney tubules of diabetic rats - Br J Nutr. 2008 Feb 6;:1-8 - "It has been documented that green tea (GT) and its catechin components improve renal failure and inhibit the growth of mesangial cells ... GT treatment significantly (P < 0.01) reduced the serum glucose, glycosylated protein, serum creatinine and blood urea N levels by 29.6 (sem 3.7), 22.7 (sem 5.2), 38.9 (sem 10) and 41.7 (sem 1.9) %, respectively ... the GT-treated group showed a significant 44 (sem 10.8) % higher creatinine clearance (Ccr) ... GT reduced the urea N, creatinine, glucose and protein excretion rates by 30 (sem 7.6), 35.4 (sem 5.3), 34.0 (sem 5.3) and 46.0 (sem 13.0) % compared with the 12 weeks diabetic group. Administration of GT to 12 weeks diabetic rats significantly (P < 0.001) prevented (99.98 (sem 0.27) % less) the accumulation of glycogen in the kidney tubules. These results indicate that in STZ diabetes, kidney function appears to be improved with GT consumption which also prevents glycogen accumulation in the renal tubules, probably by lowering blood levels of glucose. Therefore, GT could be beneficial additional therapy in the management of diabetic nephropathy" - See green tea extract at Amazon.com.

• Dietary lipoic acid-dependent changes in the activity and mRNA levels of hepatic lipogenic enzymes in rats - Br J Nutr. 2007 Dec 7;:1-9 - "Lipoic acid profoundly decreased serum and liver concentrations of TAG, and also lowered serum concentrations of phospholipid and NEFA, and the concentration of cholesterol in the liver. A hypoglycaemic effect of this compound was also observed. Lipoic acid dose-dependently decreased the activity and mRNA levels of fatty acid synthase, ATP-citrate lyase, glucose 6-phosphate dehydrogenase, malic enzyme and pyruvate kinase in the liver despite that reductions were considerably attenuated in the NADPH-producing enzymes. This compound also dose-dependently lowered the mRNA levels of spot 14, adiponutrin, stearoyl-CoA desaturase 1, and Delta5- and Delta6-desaturases. In addition, lipoic acid dose-dependently lowered serum concentrations of insulin and leptin, but increased those of adiponectin. Lipoic acid appeared to reduce hepatic lipogenesis and hence decreases serum and liver lipid levels. Alterations in serum concentrations of insulin and (or) adiponectin may trigger this consequence" - See alpha lipoic acid at Amazon.com.
• Adiponectin, the controversial hormone - Public Health Nutr. 2007 Oct;10(10A):1145-50 - "Considering the anti-inflammatory properties of adiponectin and the fact that it is negatively associated with adiposity, this cytokine could be one of the links between obesity and inflammation. The main mechanisms of action of adiponectin are directed to a protective role against atherogenic and insulin resistance processes. Research has revealed interesting new functions far beyond metabolism, such as immunity, cancer and bone formation. Contrary to all adipose-related proteins, adiponectin decreases with obesity. Most of the contradictory data surrounding adiponectin are related to plasma values and their relationship with body fat, gender differences and insulin resistance"

• Do low levels of circulating adiponectin represent a biomarker or just another risk factor for the metabolic syndrome? - Diabetes Obes Metab. 2007 May;9(3):246-58 - "The metabolic syndrome is currently defined by various combinations of insulin resistance, obesity, dyslipidaemia and hypertension. The tendency for these risk factors to appear simultaneously suggests a single aetiologic basis. A low level of circulating adiponectin is associated with the appearance of each metabolic syndrome risk factor ... An association between the metabolic syndrome and low adiponectin supports the view that the development of the metabolic syndrome may be triggered by a single underlying mechanism. Clinical studies in the future may show that a low level of circulating adiponectin is a primary biomarker for a specific cluster of metabolic syndrome risk factors rather than all the possible combinations of risk factors currently used to identify the metabolic syndrome"
• Decreased Plasma Adiponectin is Associated with Insulin Resistance and HDL Cholesterol in Overweight Subjects - Endocr J. 2007 May;54(2):221-6 - "In overweight subjects, adiponectin levels negatively correlated with body weight (r = -0.35, P<0.001), body mass index (BMI) (r = -0.28, P<0.006), systolic blood pressure (r = -0.21, P<0.04), fasting insulin (r = -0.19, P<0.01) and HOMA-IR (r = -0.20, P<0.01) and positively with high-density lipoprotein cholesterol (HDL-C) (r = 0.27, P<0.009).
