The use of benefi cial fungi and bacteria can improve growth, yield and food quality of plants. The electrical conductivity (EC) of a nutrient solution is closely linked to better nutrition of arugula plants in a hydroponic system. Therefore, objectives of current study were to evaluate isolated and combined eff ect of inoculation with Azospirillum brasilense and Trichoderma hazianum under two ECs on root-shoot biomass, nutrition and yield of arugula in hydroponic cultivation system. The experi- ment was designed in a strip-plot block with fi ve replications in a 4 × 2 factorial scheme. The treatments were consisted of four microbial inoculations (without, A. brasilense, T. harzianum and co-inoculation of both) and two ECs (1.4 and 1.6 dS m −1). The higher EC with A. brasilense inoculation provided greater growth of arugula plants in a hydroponic system. Inoculation with A. brasilense has increased leaf area, shoot–root length, leaf chlorophyll index (LCI) and shoot ammonium accumulation while reduced root-shoot nitrate accumulation. The leaf nutrition or biofortifi cation of arugula plants with K, S, Ca, Mg, Zn, Fe, and Mn was improved under both isolated and combined inoculations of A. brasilense and T. harzianum .

Background/Aims: Screening for hepatitis B virus (HBV) is recommended in populations with anticipated prevalence ≥2%. This study surveyed HBV screening and vaccination practices of Asian American primary care providers (PCPs). Methods: Approximately 15,000 PCPs with Asian surnames in the New York, Los Angeles, San Francisco, Houston, and Chicago areas were invited to participate in a web-based survey. Asian American PCPs with ≥25% Asian patients in their practice were eligible. Results: Of 430 (2.9%) survey respondents, 217 completed the survey. Greater than 50% followed ≥200 Asian patients. Although 95% of PCPs claimed to have screened patients for HBV, 41% estimated that ≤25% of their adult Asian patients had ever been screened, and 50% did not routinely screen all Asian patients. In a multivariable analysis, the proportion of Asian patients in the practice, provider geographic origin and the number of liver cancers diagnosed in the preceding 12 months were significantly associated with a higher likelihood of screening for HBV. Over 80% of respondents reported that ≤50% of their adult Asian patients had received the HBV vaccine. Conclusions: Screening and vaccination for HBV in Asian American patients is inadequate. Measures to improve HBV knowledge and care by primary-care physicians are critically needed. (Gut Liver 2013; 7:450-457)
