    Berberine inhibits human tongue squamous carcinoma cancer tumor growth in a murine xenograft model. Ho YT, Yang JS, Lu CC, Chiang JH, Li TC, Lin JJ, Lai KC, Liao CL, Lin JG, Chung JG. Phytomedicine. 2009 Sep;16(9):887-90. Epub 2009 Mar 20. PMID: 19303753 Our primary studies showed that berberine induced apoptosis in human tongue cancer SCC-4 cells in vitro. But there is no report to show berberine inhibited SCC-4 cancer cells in vivo on a murine xenograft animal model. SCC-4 tumor cells were implanted into mice and groups of mice were treated with vehicle, berberine (10mg/kg of body weight) and doxorubicin (4mg/kg of body weight). The tested agents were injected once per four days intraperitoneally (i.p.), with treatment starting 4 weeks prior to cells inoculation. Treatment with 4mg/kg of doxorubicin or with 10mg/kg of berberine resulted in a reduction in tumor incidence. Tumor size in xenograft mice treated with 10mg/kg berberine was significantly smaller than that in the control group. Our findings indicated that berbeirne inhibits tumor growth in a xenograft animal model. Therefore, berberine may represent a tongue cancer preventive agent and can be used in clinic.

    Vitamin D Deficiency in the Morbidly Obese. Buffington C, Walker B, Cowan GS Jr, Scruggs D. Obes Surg. 1993 Nov;3(4):421-424. PMID: 10757956 These data suggest that low vitamin D may be associated with obesity per se. Hypovitaminosis D, when it is found in post-bariatric surgery patients, may not be caused by the surgery since it may have been present to some degree pre-operatively.

    Fish consumption and risk of subclinical brain abnormalities on MRI in older adults. Virtanen JK, Siscovick DS, Longstreth WT Jr, Kuller LH, Mozaffarian D. Neurology. 2008 Aug 5;71(6):439-46. PMID: 18678827 doi: 10.1212/01.wnl.0000324414.12665.b0 Conclusions: Among older adults, modest consumption of tuna/other fish, but not fried fish, was associated with lower prevalence of subclinical infarcts and white matter abnormalities on MRI examinations. Our results add to prior evidence that suggest that dietary intake of fish with higher eicosapentaenoic acid and docosahexaenoic acid content, and not fried fish intake, may have clinically important health benefits

    The high prevalence of vitamin D insufficiency across Australian populations is only partly explained by season and latitude. van der Mei IA, Ponsonby AL, Engelsen O, Pasco JA, McGrath JJ, Eyles DW, Blizzard L, Dwyer T, Lucas R, Jones G. Environ Health Perspect. 2007 Aug;115(8):1132-9. PMID: 17687438 doi: 10.1289/ehp.9937. Conclusion Vitamin D insufficiency is common over a wide latitude range in Australia. Season appears to be more important than latitude, but both accounted for less than one-fifth of the variation in serum 25(OH)D levels, highlighting the importance of behavioral factors. Current sun exposure guidelines do not seem to fully prevent vitamin D insufficiency, and consideration should be given to their modification or to pursuing other means to achieve vitamin D adequacy.

    Are omega-3 fatty acids options for prevention and treatment of cognitive decline and dementia? Cederholm T, Palmblad J. Curr Opin Clin Nutr Metab Care. 2009 Dec 16. [Epub ahead of print] PMID: 20019606 PURPOSE OF REVIEW: To report recent data on the potential role of omega-3 fatty acids (n-3 FA) found in oily fish, especially docosahexaenoic acid (DHA), to prevent and treat cognitive decline and Alzheimer's disease. RECENT FINDINGS: Observational studies still provide conflicting results, in which the majority indicate beneficial effects on cognition, both when assessed as a continuous variable or as incident dementia, mainly Alzheimer's disease. Experimental studies have demonstrated potentially ameliorating effects of eicosapentaenoic acid (EPA) and DHA on amyloid fragment formation, signal transduction including upregulation of the apolipoprotein receptor SorLA, as well as on angiogenesis. The role of EPA and DHA metabolites on Alzheimer's disease pathology is under investigation. Recently, three randomized intervention studies, with duration up to 6 months have been reported. In contrast to a small study from Taiwan, no positive overall effects were reported from the Swedish OmegAD Study or from a Dutch study, although post hoc analyses indicate that selected individuals with mild forms of Alzheimer's disease or cognitive decline may respond to treatment. SUMMARY: No firm conclusions can be drawn. Based on epidemiological data, fish including oily fish could be advised as part of a balanced diet for public health purpose, although the evidence for better cognition is only fairly consistent. It is unlikely that n-3 FA will emerge as a treatment option in general for improving cognitive function in patients with Alzheimer's disease. n-3 FA, especially DHA, may turn out as an adjuvant therapy in selected cases. Further long-term intervention studies on individuals with mild cognitive reductions are awaite"

    "The coconut is called the tree of life for it has been providing us, humans, food and drink, materials for housing, fuel and many industrial uses. And its medicinal uses are many and varied. The latest medical potential of products of the coconut first identified by Jon Kabara and others in the 70s, is the anti-bacterial, anti-viral and anti-fungal activity of its medium chain fatty acids, particularly lauric acid (C12:0) in its monoglyceride form (monolaurin or ML). The first clinical trial ever of ML was on 15 HIV-infected patients reporting regularly at the San Lazaro Hospital, Manila who, never having received any anti-HIV medication, were randomly assigned to 3 treatment groups: 7.2 g ML, 2.4 g ML and 50 ML of coconut oil daily for 6 months. The San Lazaro Hospital Team was led by Eric Tayag."

Could Omega-3s Boost Blood Fat Levels?: MedlinePlus - 0 views

  •  
    "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

    Consuming fructose-sweetened, not glucose-sweetened, beverages increases visceral adiposity and lipids and decreases insulin sensitivity in overweight/obese humans. Stanhope KL, Schwarz JM, Keim NL, Griffen SC, Bremer AA, Graham JL, Hatcher B, Cox CL, Dyachenko A, Zhang W, McGahan JP, Seibert A, Krauss RM, Chiu S, Schaefer EJ, Ai M, Otokozawa S, Nakajima K, Nakano T, Beysen C, Hellerstein MK, Berglund L, Havel PJ. J Clin Invest. 2009 May;119(5):1322-34. Epub 2009 Apr 20. PMID: 19381015 doi: 10.1172/JCI37385. Studies in animals have documented that, compared with glucose, dietary fructose induces dyslipidemia and insulin resistance. To assess the relative effects of these dietary sugars during sustained consumption in humans, overweight and obese subjects consumed glucose- or fructose-sweetened beverages providing 25% of energy requirements for 10 weeks. Although both groups exhibited similar weight gain during the intervention, visceral adipose volume was significantly increased only in subjects consuming fructose. Fasting plasma triglyceride concentrations increased by approximately 10% during 10 weeks of glucose consumption but not after fructose consumption. In contrast, hepatic de novo lipogenesis (DNL) and the 23-hour postprandial triglyceride AUC were increased specifically during fructose consumption. Similarly, markers of altered lipid metabolism and lipoprotein remodeling, including fasting apoB, LDL, small dense LDL, oxidized LDL, and postprandial concentrations of remnant-like particle-triglyceride and -cholesterol significantly increased during fructose but not glucose consumption. In addition, fasting plasma glucose and insulin levels increased and insulin sensitivity decreased in subjects consuming fructose but not in those consuming glucose. These data suggest that dietary fructose specifically increases DNL, promotes dyslipidemia, decreases insulin sensitivity, and increases visceral adiposity in overweight/obese adults.

    Efficacy of berberine in patients with type 2 diabetes mellitus. Yin J, Xing H, Ye J. Metabolism. 2008 May;57(5):712-7. PMID: 18442638 doi: 10.1016/j.metabol.2008.01.013. Fasting plasma insulin and homeostasis model assessment of insulin resistance index were reduced by 28.1% and 44.7% (P<.001), respectively. Total cholesterol and low-density lipoprotein cholesterol were decreased significantly as well. During the trial, 20 (34.5%) patients experienced transient gastrointestinal adverse effects. Functional liver or kidney damages were not observed for all patients. In conclusion, this pilot study indicates that berberine is a potent oral hypoglycemic agent with beneficial effects on lipid metabolism In summary, that berberine is a potent oral hypoglycemic agent with modest effect on lipid metabolism. It is safe and the cost of treatment by berberine is very low. It may serve as a new drug candidate in the treatment of type 2 diabetes. However, this is a pilot study. The efficacy of berberine needs to be tested in a much larger population and characterized as a function of the known duration of the diabetes. Further studies are needed to evaluate the action of berberine on type 2 diabetes in other ethnic groups.

Soy compounds may not prevent bone loss: MedlinePlus - 0 views

  •  
    "Wednesday, December 9, 2009 By Amy Norton NEW YORK (Reuters Health) - Supplements containing soy isoflavones may do little to preserve women's bone mass after menopause. In a study of more than 200 women ages 46 to 65, researchers found that the soy supplement did not appear to ward off bone-density loss over 3 years. In general, women on the supplement showed the same degree of bone loss as those given a placebo -- though there was some evidence that a higher dose helped protect bone density in the hip. The findings, reported in the American Journal of Clinical Nutrition, add to a conflicting body of research on soy and postmenopausal bone health. Some studies have suggested that soy-based foods, isolated soy protein or isoflavone-containing supplements may be beneficial, while others have found no advantage. Isoflavones are natural chemicals found in soybeans and certain other plant foods that are structurally similar to estrogen, and may have certain estrogen-like effects in the human body. Since declining estrogen levels after menopause spur bone-density loss, isoflavone supplements could theoretically protect women's bone mass. The current findings, however, do not support that theory."

    Vitamin D and mood disorders among women: an integrative review. Murphy PK, Wagner CL. J Midwifery Womens Health. 2008 Sep-Oct;53(5):440-6. Review. PMID: 18761297 Four of six studies reviewed imparted significant results, with all four showing an association between low 25(OH)D levels and higher incidences of four mood disorders: premenstrual syndrome, seasonal affective disorder, non-specified mood disorder, and major depressive disorder. This review indicates a possible biochemical mechanism occurring between vitamin D and mood disorders affecting women, warranting further studies of these variables using rigorous methodologies.
