Brucella was an intracellular parasite, which could infect special livestock and humans. After infected by Brucella, livestock’s reproductive system could be affected and destroyed resulting in huge economic losses. More seriously, it could be contagious from livestock to humans. So far, there is no available vaccine which is safe enough for humans. On this point, subunit vaccine has become the new breakthrough of conquering brucellosis. In this study, Brucella rL7/L12-BLS fusion protein was used as an antigen to immunize rabbits to detect the immunogenicity. The results of antibody level testing assay of rabbit antiserum indicated rL7/L12-BLS fusion protein could elicit rabbits to produce high-level IgG. And gamma interferon (IFN-γ) concentrations in rabbit antiserum were obviously up-regulated in both the rL7/L12 group and rL7/L12-BLS group. Besides, the results of quantitative real-time PCR (qRT-PCR) showed the IFN-γ gene’s expression levels of both the rL7/L12 group and rL7/L12-BLS group were obviously up-regulated. All these results suggested Brucella L7/L12 protein was an ideal subunit vaccine candidate and possessed good immunogenicity. And Brucella lumazine synthase (BLS) molecule was a favorable transport vector for antigenic protein. © 2016 Springer Science+Business Media New York

OBJECTIVE: This meta-analysis examined the relationship between excess body weight or body mass index (BMI) and risk of thyroid cancer. METHODS: PubMed®, MEDLINE®, EMBASE™ and Academic Search™ Premier databases were searched to identify cohort studies examining the effect of being overweight or obese on the risk of thyroid cancer. RESULTS: The inclusion criteria were met by seven cohort studies (total number of thyroid cancer cases, 5154). The pooled relative risk (RR) of thyroid cancer was 1.13 (95% confidence interval [CI] 1.04, 1.22) for overweight. Obesity was also linked with increased thyroid cancer risk in males and females, the strength of the association increasing with increasing BMI. The combined RR of thyroid cancer was 1.18 (95% CI 1.11, 1.25) for excess body weight (overweight and obesity combined). Being overweight was associated with a significant increase in thyroid cancer risk among non-Asians, but not among Asians. Overweight, obesity and excess body weight were all associated with papillary thyroid carcinoma risk. CONCLUSIONS: The association between overweight/ obesity/excess body weight and thyroid cancer risk was confirmed. © SAGE Publications Ltd 2012.
