(SACRAMENTO, Calif.) - Osteoporosis affects many women and can cause painful, disabling and even life-threatening fractures. Researchers from the UC Davis Department of Internal Medicine are seeking a simple, inexpensive way to prevent the disease. Strontium citrate is a widely available, over-the-counter dietary supplement promoted to "improve bone health." Strontium is a natural element found in bone in all people. Strontium citrate is another form of strontium ranelate, a proven medication prescribed across Europe and Australia to treat and prevent osteoporosis and related fractures. Unlike pharmaceuticals, strontium citrate is not a prescribed medication and is inexpensive.

Subfractionation of Lipoproteins 101 Let's review some subfractionation techniques. On the market 3 main methods exist. They all work. Dr. Davis highly prefers NMR for its subtleties, scope, and particle counts. Superko and Krauss are affiliated with Berkeley HeartLab which uses GGE (BHL). Density gradient ultracentrifugation is very popular among our members (VAP-II and VAP). Recently, Krauss appears to be introducing a new technology based on ion-mobility. Basically, the denser the particle, the faster and more mobile the particle moves through a gel (GGE). The denser the particle, the smaller the diameter (Angstroms or nanometers) as determined via electromagnetic resonance (NMR) or absorbance via density ultracentrifugation (VAP, which are indirectly compared to known sizes).

Berberine inhibits adipogenesis in high-fat diet-induced obesity mice. Hu Y, Davies GE. Fitoterapia. 2009 Oct 25. [Epub ahead of print] PMID: 19861153 doi:10.1016/j.fitote.2009.10.010 Our previous studies illustrated that berberine inhibited adipogenesis in murine-derived 3T3-L1 preadipocytes and human white preadipocytes. In this study, the effects of berberine on the adipogenesis of high-fat diet-induced obesity (FD) or normal diet (ND) mice and possible transcriptional impact are investigated. The results demonstrated that in FD mice, berberine reduced mouse weight gain and food intake and serum glucose, triglyceride, and total cholesterol levels accompanied with a down-regulation of PPARgamma expression and an up-regulation of GATA-3 expression. Berberine had no adverse effects on ND mice. These encouraging findings suggest that berberine has excellent pharmacological potential to prevent obesity.

Should new vitamin D recommendations be made? According to a new study carried out at the University of California at Davis, the recommended dose of vitamin D that most experts recommend taking is too low during the winter months when there's less direct sunlight

Omega-3 fatty acids: evidence basis for treatment and future research in psychiatry. Freeman MP, Hibbeln JR, Wisner KL, Davis JM, Mischoulon D, Peet M, Keck PE Jr, Marangell LB, Richardson AJ, Lake J, Stoll AL. J Clin Psychiatry. 2006 Dec;67(12):1954-67. Review. Erratum in: J Clin Psychiatry. 2007 Feb;68(2):338. PMID: 17194275 Conclusions: The preponderance of epidemiologic and tissue compositional studies supports a protective effect of omega-3 EFA intake, particularly eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), in mood disorders. Meta-analyses of randomized controlled trials demonstrate a statistically significant benefit in unipolar and bipolar depression (p=.02). The results were highly heterogeneous, indicating that it is important to examine the characteristics of each individual study to note the differences in design and execution. There is less evidence of benefit in schizophrenia. EPA and DHA appear to have negligible risks and some potential benefit in major depressive disorder and bipolar disorder, but results remain inconclusive in most areas of interest in psychiatry. Treatment recommendations and directions for future research are described. Health benefits of omega-3 EFA may be especially important in patients with psychiatric disorders, due to high prevalence rates of smoking and obesity and the metabolic side effects of some psychotropic medications.

A German group has now shown that the important inflammatory marker, tumor necrosis factor (TNF), is also reduced by vitamin D supplementation. Many studies have implicated increased TNF levels in promoting cancer. In this study, a modest vitamin D dose of 3320 units (83 micrograms) was given vs. placebo. The 25-hydroxy D level reached in the treated group was 34.2 ng/ml (85.5 nmol/L), which resulted in a 26.5% reduction in TNF compared with 18.7% reduction (?) in the placebo group.
