Omega fatty acid balance can alter immunity and gene expression - 0 views

  •  
    Floyd Chilton and colleagues wanted to examine whether theses fatty acids might have other effects, and developed a dietary intervention strategy in which 27 healthy humans were fed a controlled diet mimicking the w6/w3 ratios of early humans over 5 weeks. They then looked at the gene levels of immune signals and cytokines (protein immune messengers), that impact autoimmunity and allergy in blood cells and found that many key signaling genes that promote inflammation were markedly reduced compared to a normal diet, including a signaling gene for a protein called PI3K, a critical early step in autoimmune and allergic inflammation responses. This study demonstrates, for the first time in humans, that large changes in gene expression are likely an important mechanism by which these omega fatty acids exert their potent clinical effects

Harvard study confirms health risk from BPA leaching - 0 views

  • Critics of the chemical bisphenol A or BPA have received powerful new ammunition in the form of a study from the Harvard School of Public Health (HSPH) which confirmed that the substance can leach from polycarbonate drinking bottles into humans. The study revealed that participants who drank for a week from polycarbonate bottles and baby bottles showed a two-thirds increase of BPA in their urine. According to HSPH: “The study is the first to show that drinking from polycarbonate bottles increased the level of urinary BPA, and thus suggests that drinking containers made with BPA release the chemical into the liquid that people drink in sufficient amounts to increase the level of BPA excreted in human urine.”

Vitamin D - Linus Pauling Institute at Oregon State University - 0 views

  •  
    Vitamin D is a fat-soluble vitamin that is essential for maintaining normal calcium metabolism (1). Vitamin D3 (cholecalciferol) can be synthesized by humans in the skin upon exposure to ultraviolet-B (UVB) radiation from sunlight, or it can be obtained from the diet. Plants synthesize ergosterol, which is converted to vitamin D2 (ergocalciferol) by ultraviolet light. Vitamin D2 is less active in birds than vitamin D3 and may also be less active in humans (2). When exposure to UVB radiation is insufficient for the synthesis of adequate amounts of vitamin D3 in the skin, adequate intake of vitamin D from the diet is essential for health.

VitD Duration of Vitamin D Synthesis in Human Skin - 0 views

  •  
    Vitamin D production in human skin occurs only when UV radiation exceeds a threshold. From simulations of UV irradiances, the VitD www page ( http://zardoz.nilu.no/~olaeng/fastrt/VitD.html) computes the daily duration of dermal vitamin D production at midday when UV radiation exceeds the required threshold. The daily duration depends on latitude, time, total ozone, clouds, aerosols, surface reflectivity and altitude all of which can be specified by the user

    Addition of milk prevents vascular protective effects of tea. Lorenz M, Jochmann N, von Krosigk A, Martus P, Baumann G, Stangl K, Stangl V. Eur Heart J. 2007 Jan;28(2):219-23. Epub 2007 Jan 9. PMID: 17213230 doi:10.1093/eurheartj/ehl442 In conclusion, milk may counteract the favourable health effects of tea on vascular function. The finding that the tea-induced improvement of vascular function in humans is completely attenuated after addition of milk may have broad implications on the mode of tea preparation and consumption. In addition, it indicates that caution is warranted in the design of studies involving nutritional flavonoids.

    Enriched eggs as a source of N-3 polyunsaturated fatty acids for humans. Lewis NM, Seburg S, Flanagan NL. Poult Sci. 2000 Jul;79(7):971-4. Review. PMID: 10901195 Plasma triglycerides (TG) are decreased by addition of n-3 PUFA-enriched eggs to the diet. N-3 PUFA may influence LDL particle size, causing a shift toward a less atherogenic particle. Blood platelet aggregation is significantly decreased in participants consuming n-3 PUFA-enriched eggs. Overall results of studies to date demonstrate positive effects and no negative effects from consumption of n-3-enriched eggs. Three n-3 PUFA-enriched eggs provide approximately the same amount of n-3 PUFA as one meal with fish. It is recommended that n-3 PUFA-enriched eggs be used as one source of n-3 PUFA to increase individual consumption to meet the current Canadian recommendations

Ursolic acid - Wikipedia, the free encyclopedia - 0 views

  •  
    Ursolic acid is a pentacyclic triterpene acid, used in cosmetics,[2] that is also capable of inhibiting various types of cancer cells by inhibiting the STAT3 activation pathway[3][4] and human fibrosarcoma cells by reducing the expression of matrix metalloproteinase-9 by acting through the glucocorticoid receptor. Ursolic acid is present in many plants, including apples, basil, bilberries, cranberries, elder flower, peppermint, rosemary, lavender, oregano, thyme, hawthorn, prunes. Apple peels contain high quantity of ursolic acid and related compounds which are responsible for the anti-cancer activity of apple. Ursolic acid can also serve as a starting material for synthesis of more potent bioactive derivatives, such as anti-tumor agents

Pascal's Wager and Pandemic Influenza - Vitamin D Newsletter Nov 2005 - 0 views

  •  
    EPIDEMICS' TIMING DETERMINED BY LATITUDEGoing back to 1945, Hope-Simpson discovered that influenza epidemics above 30 degrees latitude in both hemispheres occurred during the six months of least solar radiation and that outbreaks in the tropics almost always occured during the rainy season. He thus concluded, "Latitude alone broadly determines the timing of the epidemics in the annual cycle, a relationship that suggests a rather direct effect of some component of solar radiation acting positively or negatively upon the virus, the human host, or their interaction." That is, something may be regularly reducing our immunity every fall and winter. In 2003 researchers confirmed that influenza epidemics in the tropics occur, with few exceptions, during the rainy season, when vitamin D levels should be falling

Multiple Sclerosis Caused by Vitamin D Deficiency - 0 views

  •  
    NaturalNews) Researchers from Oxford University and the University of British Columbia have discovered that Vitamin D deficiency affects a section of the human genome already linked with multiple sclerosis (MS) risk, adding further weight to theories that this vitamin deficiency might play a role in development of the disease. "Here we show that the main environmental risk candidate -- vitamin D -- and the main gene region are directly linked and interact," said co-author George Ebers.

    People in Asia have been eating fermented foods for more than 1,000 years. One vegan fermented food, renowned in Asia for its ability to protect against heart attacks, was recently shown to have a powerful ability in lab experiments to prevent formation of the clumps of tangled protein involved in Alzheimer's disease. if this works as well in the human brain as scientists expect, it will be a great addition to the tables of anyone who is concerned about this terrible disease

Blind Girl Can See Thanks to Umbilical Cord-Based Adult Stem Cell Treatment - 0 views

    Blind Girl Can See Thanks to Umbilical Cord-Based Adult Stem Cell Treatment London, England (LifeNews.com) -- Born two years ago with severe eye problems, Dakota Clarke could not even see well enough to recognize her own mother and father. But now the parents of the little girl, who is registered blind, say she can make out their faces for the first time after pioneering stem cell treatment. The couple gave up work to raise well over $40,000 to fly their daughter to China for the treatment, which remains at the experimental level in Britain -- because the nation has been too preoccupied with embryonic stem cells and human cloning. They returned home this week convinced that Dakota can now see colors, lights and objects around her as a result. They hope further therapy will give her a lifetime of sight. "It's nothing short of a miracle for us," said Mr Clarke, a former engineer. "She can see the world for the first time." In Dakota's case, cells were administered intravenously through her hairline and reportedly traveled towards her optic nerve, repairing the damaged area. The stem cells came from umbilical cords donated by Chinese mothers. Despite the obvious success, some doctors are talking down the results simply because the treatments aren't approved in England. Pro-life advocates say the results are yet another showing of how adult stem cells outpace their embryonic cousins both ethically and when used in treatments.
