Chow Line: Coconut oil unlike other saturated fat (for 12/9/07)
"I've always read that you should avoid coconut oil because of its high level of saturated fat. But I recently heard it is actually healthful and can help you lose weight. Is that true?
Most nutritionists don't believe consuming coconut oil will help with weight loss -- the evidence is far from conclusive on that point. But most will also concede that the oil may not be the demon many think it is.
To be honest, when it comes to nutrition research, the "truth" often seems elusive. Studies pronounce one verdict and then new findings point in another direction. That's simply the nature of the scientific process and the complexity surrounding nutrition and health. As long as we persist in hunting for more precise answers, we'll continue to encounter surprises. "
(WO/2006/108276) A METHOD OF TREATING CANCER USING DICHLOROACETATE
"The invention relates to the use of dichloroacetate and chemical equivalents thereof for the treatment of cancer by inducing apoptosis or reversing apoptosis-resistance in a cell Preferably, the dosage is 10-100 mg/kg Preferably, sodium dichloroacetate is used.

Small molecule offers big hope against cancer - ExpressNews - University of Alberta
"January 16, 2007 - Edmonton - DCA is an odourless, colourless, inexpensive, relatively non-toxic, small molecule. And researchers at the University of Alberta believe it may soon be used as an effective treatment for many forms of cancer."
DCA Research Information
"DCA is an odourless, colourless, inexpensive, relatively non-toxic, small molecule. And researchers at the University of Alberta believe it may soon be used as an effective treatment for many forms of cancer.
Dr. Evangelos Michelakis, a professor at the U of A Department of Medicine, has shown that dichloroacetate (DCA) causes regression in several cancers, including lung, breast, and brain tumors.
Michelakis and his colleagues, including post-doctoral fellow Dr. Sebastien Bonnet, have published the results of their research in the journal Cancer Cell"
Defining Adequate Vitamin D Intake : Cross-sectional and Intervention Studies

Doctoral dissertation (article-based)
In summary, vitamin D intake remains inadequate among the target groups of this thesis, as reflected by seasonal variation in calcitropic hormones and bone metabolism. Dietary intake of vitamin D should be increased to achieve at least an adequate vitamin D status (S-25-OHD>50 nmol/l) and possibly an optimal vitamin D status (S-25-OHD>80 nmol/l) throughout the year. This could be accomplished by introducing new vitamin D-fortified foods to the market.

Doctoral dissertation (article-based)
It seems likely that low vitamin D levels are related to fatigue fractures, and that an increasing trend exists between TRACP-5b bone resorption marker elevation and fatigue fracture incidence. Though seldom detected by plain radiography, fatigue fractures often underlie unclear lower leg stress-related pain occurring in the distal parts of the tibia. Femoral neck fatigue fractures, when displaced, lead to long-term morbidity in a high percentage of patients, whereas, when non-displaced, they do not predispose patients to subsequent adverse complications. Importantly, an educational intervention can diminish the incidence of fracture displacement by enhancing awareness and providing instructions for earlier diagnosis of fatigue fractures
YouTube - Vitamin D: It's Not Just For Bones Anymore
David Feldman, MD, professor of medicine at Stanford, explores the biological action of Vitamin D beyond its widely understood role in the information and maintenance of bone. Emerging therapeutic uses of the vitamin include the prevention and treatment of breast, prostate and colon cancer, chronic kidney disease and arthritis, among other conditions.

CONCLUSIONS: These data suggest that variable responsiveness to UVB radiation is evident among individuals, causing some to have low vitamin D status despite abundant sun exposure. In addition, because the maximal 25(OH)D concentration produced by natural UV exposure appears to be approximately 60 ng/ml, it seems prudent to use this value as an upper limit when prescribing vitamin D supplementation.

Vitamin D (Cholecalciferol, Calcitriol)
Bioactive vitamin D or calcitriol is a steroid hormone that has long been known for its important role in regulating body levels of calcium and phosphorus, and in mineralization of bone. More recently, it has become clear that receptors for vitamin D are present in a wide variety of cells, and that this hormone has biologic effects which extend far beyond control of mineral metabolism.
The active form of vitamin D binds to intracellular receptors that then function as transcription factors to modulate gene expression. Like the receptors for other steroid hormones and thyroid hormones, the vitamin D receptor has hormone-binding and DNA-binding domains. The vitamin D receptor forms a complex with another intracellular receptor, the retinoid-X receptor, and that heterodimer is what binds to DNA. In most cases studied, the effect is to activate transcription, but situations are also known in which vitamin D suppresses transcription.
Each of the forms of vitamin D is hydrophobic, and is transported in blood bound to carrier proteins. The major carrier is called, appropriately, vitamin D-binding protein. The halflife of 25-hydroxycholecalciferol is several weeks, while that of 1,25-dihydroxycholecalciferol is only a few hours.
The vitamin D receptor binds several forms of cholecalciferol. Its affinity for 1,25-dihydroxycholecalciferol is roughly 1000 times that for 25-hydroxycholecalciferol, which explains their relative biological potencies
Common genetic variants of the vitamin D binding protein (DBP) predict differences in response of serum 25-hydroxyvitamin D [25(OH)D] to vitamin D supplementation. - [Clin Biochem. 2009] - PubMed Result
BACKGROUND: To determine the effect of vitamin D binding protein (DBP) genotypes on 25-hydroxyvitamin D [25(OH)D] changes with vitamin D supplements, we studied 98 adults receiving 600 or 4000 IU/d vitamin D(3) for one year. METHODS: The DBP functional variant, T436K, was genotyped by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). RESULTS: Mean 25(OH)D increases were 97% for TT (n=48), 151% for TK (n=31) and 307% (n=6) for KK genotypes (p=.004). CONCLUSIONS: As with baseline 25(OH)D, T436K genotype predicts 25(OH)D changes after long-term vitamin D supplementation.
Common genetic variants of the vitamin D binding protein (DBP) predict differences in response of serum 25-hydroxyvitamin D [25(OH)D] to vitamin D supplementation.
