"High serum selenium associated with elevated LDL and total cholesterol By Helen Albert 21 January 2010 Atherosclerosis 2009; Advance online publication MedWire News: High levels of serum selenium are associated with elevated total and low-density lipoprotein (LDL) cholesterol, report US researchers. The results add weight to those of a previous UK study, reported by MedWire News, that reported an association between high plasma selenium and an adverse lipid profile. Eliseo Guallar (Johns Hopkins University Bloomberg School of Public Health, Baltimore, Maryland) and colleagues carried out a cross-sectional analysis of 1159 individuals aged 56.8 years on average who participated in the National Health and Nutrition Examination Survey (NHANES) 2003-2004."

Mice injected with cancer cells experienced significantly elevated levels of C-reactive protein, white blood cells, and lipid peroxidation compared with control mice. These levels were reduced in animals that received cisplatin and/or DHA. While treatment with 125 mg/kg DHA inhibited tumor growth by 38 percent compared to untreated animals, 250 mg/kg suppressed tumor growth by 79 percent, which was a greater effect than that of cisplatin alone (which was associated with a 55 percent reduction). The combination of DHA and cisplatin resulted in an 81 percent inhibition of growth, while reducing elevated white blood cell levels (leukocytosis) to normal levels. Treatment with the higher dose of DHA alone was associated with a similar reduction in white blood cells, which, when elevated, are associated with tumor growth. A strong relationship was observed between tumor growth and white blood cell levels as well as C-reactive protein levels. In another experiment with rats treated with cisplatin, the addition of 250 mg/kg DHA prevented lethal kidney toxicity in 88 percent of the animals that received it, while none of the rats that received cisplatin alone survived.

"THURSDAY, Dec. 17 (HealthDay News) -- In a surprise finding, Canadian researchers report that the immediate effect of the fish oil fatty acids that are good for the heart is a short-term increase in blood fats and the molecules that help them form clots. "We were surprised to find that the acute response has some potentially negative effects in comparison to what you might expect from chronic, long-term intake," said Lindsay E. Robinson, an associate professor of nutrition at the University of Guelph, and leader of the group reporting the finding in the January issue of the Journal of Nutrition. However, the study results shouldn't affect the current recommendation for eating more oily fish to get the omega-3 polyunsaturated acids that reduce the risk of blood clots that can cause heart attacks and stroke, Robinson said. "The recommendation to increase intake is very well-studied, and this doesn't change it," she said. And the effects were seen in a selected group of middle-aged men with metabolic syndrome, a combination of high blood pressure, obesity and elevated blood fat levels, Robinson noted. In the study, eight men had controlled intake of three regimens: high doses of omega-3 fatty acids, low doses of them and just plain water. Robinson and her colleagues measured several blood components involved in clotting, including fats and clotting factors such as plasminogen-activator inhibitor-1 (PAI-1) for the following eight hours. PAI-1 inhibits the destruction of blood clots, so high levels of it in the blood increase the risk of artery-blocking clots. The researchers found that both omega-3 fatty acid regimens increased blood fat and clotting factor activity. But the increase in clotting factor was greater for the higher doses of omega-3 fatty acids than for the lower intakes. Robinson said her group hopes to do further studies of the immediate effects of omega-3 fatty acid intake. "We need to look at the mechanisms, why blood lipid levels go up," she

Berberine is a novel cholesterol-lowering drug working through a unique mechanism distinct from statins. Kong W, Wei J, Abidi P, Lin M, Inaba S, Li C, Wang Y, Wang Z, Si S, Pan H, Wang S, Wu J, Wang Y, Li Z, Liu J, Jiang JD. Nat Med. 2004 Dec;10(12):1344-51. Epub 2004 Nov 7. PMID: 15531889 doi:10.1038/nm1135 We identify berberine (BBR), a compound isolated from a Chinese herb, as a new cholesterol-lowering drug. Oral administration of BBR in 32 hypercholesterolemic patients for 3 months reduced serum cholesterol by 29%, triglycerides by 35% and LDL-cholesterol by 25%. Treatment of hyperlipidemic hamsters with BBR reduced serum cholesterol by 40% and LDL-cholesterol by 42%, with a 3.5-fold increase in hepatic LDLR mRNA and a 2.6-fold increase in hepatic LDLR protein. Using human hepatoma cells, we show that BBR upregulates LDLR expression independent of sterol regulatory element binding proteins, but dependent on ERK activation. BBR elevates LDLR expression through a post-transcriptional mechanism that stabilizes the mRNA. Using a heterologous system with luciferase as a reporter, we further identify the 5' proximal section of the LDLR mRNA 3' untranslated region responsible for the regulatory effect of BBR. These findings show BBR as a new hypolipidemic drug with a mechanism of action different from that of statin drugs.

Introduction: nutritional and functional roles of eggs in the diet. Applegate E. J Am Coll Nutr. 2000 Oct;19(5 Suppl):495S-498S. Review. PMID: 11022998 For years, eggs have been held up as a powerhouse of nutrition. This reputation has been due to eggs' exceptional nutrition profile as a nutrient-dense food containing high quality protein and a substantial amount of many essential vitamins and minerals. Unfortunately their position on the nutrition pedestal fell with the discovery that they are also a source of dietary cholesterol. The most recent scientific research not only returns eggs to their golden past, but elevates their position as a functional food and ultimately provides more reasons than ever to consume eggs. In February 2000, scientists convened at a conference in Amelia Island, Florida, to discuss the latest research about the role of eggs in disease prevention and the promotion of health. This supplement of the Journal of the American College of Nutrition (JACN) presents compelling scientific evidence about eggs' functional food attributes, reaffirms that eggs have a minimal effect on blood cholesterol levels and presents new research on the contribution of eggs to the American diet. For health professionals, this issue provides a new scientifically based viewpoint on eggs and their role in health and nutrition, a viewpoint that should be imparted to all consumers in an effort to ensure optimal health and well-being.

"November 25, 2009 | Michael O'Riordan Orlando, FL - Treating healthy women with low LDL cholesterol but elevated high-sensitivity C-reactive protein (hsCRP) levels with rosuvastatin (Crestor, AstraZeneca) cuts their risk of cardiovascular events in half, according to a new analysis of Justification for the Use of Statins in Primary Prevention: An Intervention Trial Evaluating Rosuvastatin (JUPITER). The reduction in risk is consistent with the reduction observed in the overall trial, and with the 42% benefit observed in men.

"(NaturalNews) Regularly eating high levels of tofu may increase the risk of the memory loss associated with dementia, according to a new study conducted by researchers from Loughborough University in the United Kingdom, and published in the journal Dementias and Geriatric Cognitive Disorders. Prior research has found that women over the age of 65 who receive hormone therapy may double their risk of dementia. This may occur because estrogen promotes cell growth, which may actually do damage to the aging brain, Hogervorst said. Alternately, high levels of estrogen might enhance the cell-damaging effects of free radicals. Hogervorst also noted that much of tofu consumed by study participants might have been preserved with formaldehyde, a common practice in Indonesia. Formaldehyde has been strongly linked to various forms of cell damage, and might be responsible for the memory effects observed. Prior research has found that older Japanese-American men who consumed high levels of tofu are also at an elevated risk for dementia, however. Researchers investigated the connection between memory loss and diet for 719 elderly urban and rural residents of Java, Indonesia. The found that those who ate tofu at least once per day performed significantly worse on memory tests than those who ate tofu less frequently. The effect was particularly strong among those over the age of 68."

"From 1955 to 1990, all infants in East Germany received 600,000 IU of Vitamin D every three months for a total of 3,600,000 IU at age 18 months. With the 400 IU/day recommendation of the American Pediatric Association in mind, I ran across this amazing paper while surfing Medline for Vitamin D. According to this paper, all infants in the German Democratic Republic (East Germany) received dangerously high doses of Vitamin D every three months in their doctors office. The policy was in place for 35 years. The first 600,000 IU dose was given at three months and then every three months until the child was 18 months of age. This works out to an average of 6,000 IU per day (actually, for several technical reasons it is not equivalent) for 18 months. The authors collected blood before the dose and then 2 weeks after the quarterly dose to obtain 25(OH)D, 1,25(OH)D, and calcium levels on a total of 43 infants. Before the first dose, at 3 months of age, the average infant was extremely deficient (median 25(OH)D of 7 ng/ml). Two weeks after the first dose the average 25(OH)D level was 120 ng/ml, the second dose 170 ng/ml, the third dose, 180 ng/ml, the fourth dose, 144 ng/ml, the fifth dose, 110 ng/ml and after the sixth and final dose, 3.6 million total units, at age 18 months, the children had mean levels of 100 ng/ml. That is, by the 15 and 18 month doses, the children were beginning to effectively handle these massive doses. The highest level recorded in any of the 43 infants was 408 ng/ml at age 9 months, two weeks after the third 600,000 IU dose. Thirty-four percent of the infants had at least one episode of hypercalcemia but only 3 had an elevated serum 1,25(OH)D. The authors reported that all the infants appeared healthy, even the infant with a level of 408 ng/ml, that is, no clinical toxicity was noted in any of these infants."

Glucose restriction can extend normal cell lifespan and impair precancerous cell growth through epigenetic control of hTERT and p16 expression. Li Y, Liu L, Tollefsbol TO. FASEB J. 2009 Dec 17. [Epub ahead of print] PMID: 20019239 doi: 10.1096/fj.09-149328 Cancer cells metabolize glucose at elevated rates and have a higher sensitivity to glucose reduction. However, the precise molecular mechanisms leading to different responses to glucose restriction between normal and cancer cells are not fully understood. We analyzed normal WI-38 and immortalized WI-38/S fetal lung fibroblasts and found that glucose restriction resulted in growth inhibition and apoptosis in WI-38/S cells, whereas it induced lifespan extension in WI-38 cells. Moreover, in WI-38/S cells glucose restriction decreased expression of hTERT (human telomerase reverse transcriptase) and increased expression of p16(INK4a). Opposite effects were found in the gene expression of hTERT and p16 in WI-38 cells in response to glucose restriction. The altered gene expression was partly due to glucose restriction-induced DNA methylation changes and chromatin remodeling of the hTERT and p16 promoters in normal and immortalized WI-38 cells. Furthermore, glucose restriction resulted in altered hTERT and p16 expression in response to epigenetic regulators in WI-38 rather than WI-38/S cells, suggesting that energy stress-induced differential epigenetic regulation may lead to different cellular fates in normal and precancerous cells. Collectively, these results provide new insights into the epigenetic mechanisms of a nutrient control strategy that may contribute to cancer therapy as well as antiaging approaches.

"The common culprit is soy, a plant that contains chemicals with estrogen-like and anti-estrogenic properties - making it a nutritional minefield for breast cancer survivors. While Western diets are relatively low in soy - compared with the typical diet in Asia, where people eat soy daily - the percentage of Americans consuming soy at least once a week has increased from 15% in 1997 to 28% in 2003. In the meantime, studies on the effect of soy on breast cancer recurrence and mortality have been conflicting, with some showing that it can reduce risk, while others show an elevated rate of recurrent disease among high soy consumers. Now the largest study to date of soy's effect on breast cancer suggests that eating soy, even in large amounts, may not be harmful after all, and may even reduce recurrence and death from the disease. But while the findings are intriguing, not all doctors are ready to tout the benefits of tofu
