Weight loss herbal intervention therapy (W-LHIT) a non-appetite suppressing natural product controls weight and lowers cholesterol and glucose levels in a murine model. - BMC complementary and alternative medicine
The prevalence of obesity is increasing in industrialized countries. Obesity increases the risk of coronary artery disease, stroke, cancer, hypertension, and type-2 diabetes. Unfortunately, conventional obesity drug treatment is often associated with adverse effects. The objective of this study was to evaluate a novel natural formula, Weight loss herbal intervention therapy (W-LHIT), developed from traditional Chinese medicine, for weight control in a high-fat-diet (HFD) induced obesity murine model.Two sets of experiments were performed. In experiment 1, 14-week-old C57BL/6 J male mice were fed with HFD for 21 days and then separated into 3 weight-matched groups. One group continued on the HFD as obese-controls. Two groups were switched from HFD to normal fat level diet (NFD) and sham or W-LHIT treated. In experiment 2, 25-week-old obese mice, following 2 weeks acclimatization, received either W-LHIT or sham treatment while maintained on HFD. In both sets of experiments, NFD fed, age matched normal weight mice served as normal controls. Body weight and food intake were recorded. Epididymal fat pad weight, serum glucose and cholesterol levels, as well as PPARγ and FABP4 gene expression in epididymal fat tissue were analyzed at the end of the experiment.In experiment 1, W-LHIT treated obese mice lost body weight 12.2 ± 3.8% whereas sham treated mice lost 5.5 ± 2.8% by day 10 after switching from the HFD to the NFD, without reduction of chow consumption. In experiment 2, W-LHIT treated obese mice maintained on the HFD had significantly lower body weight (8 fold less) than the sham treated mice. W-LHIT treatment also reduced epididymal fat pad weight, blood cholesterol and glucose levels versus sham treated mice without reduced chow consumption. In addition, significantly increased PPARγ (peroxisome proliferator activated receptor γ) and FABP4 (fatty acid binding protein 4) gene expression were found in epdidymal fat tissues. Liver and kidney function and hematology testing results of W-LHIT treated mice were within the normal range.W-LHIT significantly and safely reduced body weight, normalized glucose and cholesterol levels in obese mice, without suppression of appetite, and increased adipocyte PPARγ and FABP4 gene expression.
Audit of manufactured products: use of allergen advisory labels and identification of labeling ambiguities. - The Journal of allergy and clinical immunology
The Food Allergy Labeling and Consumer Protection Act became effective January 1, 2006, and mandates disclosure of the 8 major allergens in plain English and as a source of ingredients in the ingredient statement. It does not regulate advisory labels.We sought to determine the frequency and language used in voluntary advisory labels among commercially available products and to identify labeling ambiguities affecting consumers with allergy.Trained surveyors performed a supermarket survey of 20,241 unique manufactured food products (from an original assessment of 49,604 products) for use of advisory labels. A second detailed survey of 744 unique products evaluated additional labeling practices.Overall, 17% of 20,241 products surveyed contain advisory labels. Chocolate candy, cookies, and baking mixes were the 3 categories of 24 with the greatest frequency (> or = 40%). Categorically, advisory warnings included "may contain" (38%), "shared equipment" (33%), and "within plant" (29%). The subsurvey disclosed 25 different types of advisory terminology. Nonspecific terms, such as "natural flavors" and "spices," were found on 65% of products and were not linked to a specific ingredient for 83% of them. Additional ambiguities included unclear sources of soy (lecithin vs protein), nondisclosure of sources of gelatin and lecithin, and simultaneous disclosure of "contains" and "may contain" for the same allergen, among others.Numerous products have advisory labeling and ambiguities that present challenges to consumers with food allergy. Additional allergen labeling regulation could improve safety and quality of life for individuals with food allergy.
Osteoarticular infectious complications in patients with primary immunodeficiencies. - Current opinion in rheumatology
To describe the incidence and management of various infectious arthritides in selected primary immunodeficiency states.Joint complications have been a well recognized finding in patients with primary immunodeficiencies for many years. Many are clearly infectious in etiology, but other apparently noninfectious joint abnormalities similar to rheumatoid arthritis have been shown to be due to an underlying infectious trigger. In humoral immunodeficiencies such as common variable immunodeficiency and X-linked agammaglobulinemia, bacterial organisms are the most common causes of infectious arthritis, but mycoplasmas and ureaplasmas are also of particular importance. In nonhumoral immunodeficiencies, noninfectious inflammatory arthritides are more prevalent, although microbiologic organisms have been reported in some cases of arthritis. Lack of appropriate culturing techniques and documentation of infectious agents may underestimate the prevalence of low-virulence infections in these patients.Infectious arthritis is a significant comorbidity associated with primary immunodeficiencies and can be the presenting feature for some patients. Prompt examination for common as well as atypical organisms is not only important for the treatment but also crucial to the understanding of the exact etiology of arthritides as a whole in these disorders.
Impact of a mass media campaign upon calls to the New South Wales Hep C helpline. - Health promotion journal of Australia : official journal of Australian Association of Health Promotion Professionals
This study evaluated the impact of a mass media campaign upon calls to the New South Wales Hep C Helpline.A time-series design was used to record the number and characteristics of calls to the helpline before, during and after the campaign.The incidence rate ratio of calls during the month of the campaign was 3.12 (95% CI 2.45-3.97) compared with the months before the campaign, and in this month more callers were < or =30 years or > or =60 years of age or non-English speaking while fewer were professionals or people directly affected by hepatitis C. Callers during the campaign were more likely to have heard about the helpline through the media and to want information about disease transmission, and less likely to want to discuss topics such as support and legal issues.The calls received by the Hep C Helpline indicate that the campaign was a useful way to generate public interest about hepatitis C. The findings indicate that telephone helplines are an information dissemination strategy that can be coupled effectively with mass media campaigns about this issue.
Benzodithiophenes potentiate differentiation of acute promyelocytic leukemia cells by lowering the threshold for ligand-mediated corepressor/coactivator exchange with retinoic acid receptor alpha and enhancing changes in all-trans-retinoic acid-regulated - Cancer research
Differentiation induction is an effective therapy for acute promyelocytic leukemia (APL), which dramatically responds to all-trans-retinoic acid (ATRA). Recent studies have indicated that combinatorial use of retinoid and nonretinoid compounds, such as histone deacetylase inhibitors, arsenics, and PKA agonists, has higher therapeutic value in this disease and potentially in other malignancies. In a screen of 370 compounds, we identified benzodithiophene analogues as potent enhancers of ATRA-induced APL cell differentiation. These effects were not associated with changes in global histone acetylation and, for the most potent compounds, were exerted at very low nanomolar concentrations, and were paralleled by enhancement of some, but not all, ATRA-modulated gene expressions. Investigating the mechanism underlying the effects of these drugs on ATRA-induced APL cell differentiation, we have shown that benzodithiophenes enhance ATRA-mediated dissociation and association of corepressor N-CoR and coactivator p300 acetyltransferase, respectively, with retinoic acid receptor (RAR) alpha proteins. These data suggest that benzodithiophenes act at the level of receptor activation, possibly by affecting posttranslational modification of the receptor (and/or coregulators), thus leading to an enhancement in ATRA-mediated effects on gene expression and APL cell differentiation. Given the specificities of these low benzodithiophene concentrations for PML-RARalpha and RARalpha, these drugs may be useful for combinatorial differentiation therapy of APL and possibly other acute myelogenous leukemia subtypes in which the overall ATRA signaling is suppressed.
