Increased surface area of halloysite nanotubes due to surface modification predicts lung inflammation and acute phase response after pulmonary exposure in mice

were 6, 18 or 54 μg of HNT s, compared to vehicle controls and the Carbon black NP (Printex 90) of 162 μg/mouse. The cellular composition of bronchoalveolar lavage (BAL) fluid was determined as a measure ...

Mixing mixed-mode designs in a national health interview survey: a pilot study to assess the impact on the self-administered questionnaire non-response.

multilevel model was used to evaluate the item non-response in the two SAQ modes while controlling for respondents’ characteristics. RESULTS: Of the eligible F2F respondents in this study, 76% (107/140) agreed ...

Dietary supplementation of tannin-extracts to lambs: effects on meat fatty acids composition and stability and on microbial characteristics.

improve the quality of RF bioeffects research. Vijayalaxmi and Prihoda applied four quality criteria to each article: 1. adequacy of exposure assessment; 2. blinded design; 3. use of positive controls; and ...

In vitro antigenotoxic activity, in silico ADME prediction and protective effects against aflatoxin B1 induced hepatotoxicity in rats of an Erythrina latissima stem bark extract

hepatotoxicity in rats induced by the same agent. Male Wistar rats were orally treated with ELBE (20 mg/kg, 50 mg/kg and 100 mg/kg) or curcumin (500 mg/kg) combined with piperine (20 mg/kg) — positive control, for ...

Determinants of unit nonresponse in multi-mode data collection: A multilevel analysis.

interviewer effects were found. Almost half (46.6%) of the variability in nonresponse was attributable to the interviewers, even in the analyses controlling for the area as potential confounder. Partial ...
