Consumption of 100% fruit juice remains controversial for its potential adverse impact on weight and displacement of essential foods in the diets of children. A systematic review of the literature published from 1995-2013 was conducted using the PubMed database to evaluate associations between intake of 100% fruit juice and weight/adiposity and nutrient intake/adequacy among children of 1 to 18 years of age. Weight status outcome measures included body mass index (BMI), BMI z-score, ponderal index, obesity, weight gain, adiposity measures, and body composition. Nutrient outcome measures included intake and adequacy of shortfall nutrients. Data extraction and analysis was conducted according to the Academy of Nutrition and Dietetics Evidence Analysis Process. Twenty-two studies on weight status provided evidence that did not support an association between 100% fruit juice consumption and weight/adiposity in children after controlling for energy intake. Limited evidence from eight studies suggests that children consuming 100% fruit juice have higher intake and adequacy of dietary fiber, vitamin C, magnesium, and potassium. Differences in methodology and study designs preclude causal determination of 100% fruit juice as sole influencer of weight status or nutrient intake/adequacy of shortfall nutrients. In context of a healthy dietary pattern, evidence suggests that consumption of 100% fruit juice may provide beneficial nutrients without contributing to pediatric obesity.

Higher SCC have been observed in goat milk than in cow milk. This study evaluated the prevalence of high SCC and determined whether increased neutrophils were a factor in high SCC. Bulk tank goat milk samples were collected from commercial dairy goat herds in California, Arkansas, Michigan, and Wisconsin. Total SCC were determined using a Fossomatic Electronic Cell Counter and microscopically using pyronin Y-methyl green stain. Differential counts were determined using Wright's-stained cytospin centrifuge preparations. Average SCC were high (6.12 log10 cells/ml; geometric mean, 1.32 x 10(6) cells/ml). The average of the Fossomatic and direct microscopic SCC indicated that 8.6% of the producers had SCC < .75 x 10(6) cells/ml and that 34.5% were< 1 x 10(6) cells/ml. The current goat milk SCC standard is 1 x 10(6) cells/ml; the cow milk SCC standard will be .75 x 10(6) cells/ml in 1993. Milk samples contained 9.9% macrophages, 2.8% lymphocytes, and 87% neutrophils. These data indicate that high SCC were prevalent and that increased neutrophils contributed to high SCC in the bulk tank goat milk.

Background: Evidence from epidemiological, clinical and animal studies suggests a link may exist between low bone density and cardiovascular disease, with inflammatory mediators implicated in the pathophysiology of both conditions. This project examined whether supplementation with soy isoflavones (IF), shown to have antiinflammatory properties, could prevent tissue expression of TNF-α and the development of skeletal pathology in an animal model of chronic inflammation.

Olanzapine is a first line medication for the treatment of schizophrenia, but it is also one of the atypical antipsychotics carrying the highest risk of weight gain. Metformin was reported to produce significant attenuation of antipsychotic-induced weight gain in patients, while the study of preventing olanzapine-induced weight gain in an animal model is absent. Berberine, an herbal alkaloid, was shown in our previous studies to prevent fat accumulation in vitro and in vivo. Utilizing a well-replicated rat model of olanzapine-induced weight gain, here we demonstrated that two weeks of metformin or berberine treatment significantly prevented the olanzapine-induced weight gain and white fat accumulation. Neither metformin nor berberine treatment demonstrated a significant inhibition of olanzapine-increased food intake. But interestingly, a significant loss of brown adipose tissue caused by olanzapine treatment was prevented by the addition of metformin or berberine. Our gene expression analysis also demonstrated that the weight gain prevention efficacy of metformin or berberine treatment was associated with changes in the expression of multiple key genes controlling energy expenditure. This study not only demonstrates a significant preventive efficacy of metformin and berberine treatment on olanzapine-induced weight gain in rats, but also suggests a potential mechanism of action for preventing olanzapine-reduced energy expenditure.

Five trials with steers new to the feedlot environment were conducted to determine the effects of one or two i.m. injections of selenium (Se) and(or) vitamin E (Vit E) on performance, health status and serum antibody response to Pasteurella haemolytica vaccination. In all trials, performance and average number of days sick per steer were not affected (P greater than .05) by single injection of Se and(or) Vit E. In Trial 1, 26 steers (avg initial wt 267 kg) were treated with 1) no Se or Vit E or 2) 25 mg Se (as Na2SeO3) plus 340 IU Vit E (as [d]-alpha-tocopheryl acetate). P. haemolytica serum immunoglobulin G (IgG) titers on d 7 and 14 were greater (P less than .05) for steers receiving 25 mg Se plus 340 IU Vit E. In Trial 2, 141 steers (avg initial wt 204 kg) were treated with 1) no Se or Vit E, 2) 25 mg Se, 3) 340 IU Vit E or 4) 25 mg Se plus 340 IU Vit E. Serum IgG titers were greater (P less than .05) only for Treatment 4 on d 6. Trial 3 was conducted using 107 steers and the same treatments as in Trial 2. By d 14, titers for treatment 4 were greater (P less than .05) than those for Treatments 1 or 3, but not greater than those for Treatment 2. In Trial 4, serum IgG titers were unaffected (P greater than .05) when 48 steers (avg initial wt 248 kg) were treated with 1) no Se or Vit E, 2) 25 mg Se plus 340 IU Vit E 14 d prior to shipping or 3) 25 mg Se plus 340 IU Vit E 14 d prior to shipping, plus repeat injection on day of arrival at the feedlot. In Trial 5, 107 steers were treated with 1) no Se or Vit E, 2) 25 mg Se plus 340 IU Vit E or 3) 50 mg Se plus 680 IU Vit E. Serum IgG titers increased linearly (P less than .01) due to treatment on d 7, 13 and 20 and a quadratic response (P less than .05) was observed on d 27. In these trials, serum antibody response to P. haemolytica vaccination was enhanced with the combination of Se and Vit E; however, performance and health status were not affected.
