Sentence examples for cu dose from inspiring English sources

We found that Cu contained in CuCNPs was significantly more toxic than an equivalent amount of free Cu dose, implying that the observed Cu toxicity was particle mediated.

Furthermore, the delivery of Cu contained in CuCNPs was more toxic than an equivalent amount of free Cu dose implying that the phenomenon was particle mediated (see Additional file 4).

We detected no responses that may represent toxic effects of the Cu dose used.

Participants received a daily Cu dose defined as the upper safe limit for human consumption, so toxic responses were not expected; liver aminotranferases were evaluated to satisfy ethical considerations.

The oral region (snout) of female C57 black mice was selectively irradiated with 225 kV X-rays (HVL 0.5 mm Cu, dose rate 0.7 Gy min−1 at 25.5 cm from the target, 250 kV Phillips).

Only Cu concentration and sex were chosen for the model, whereas total volume, daily Cu dose, and quality of the test waters ingested ("plain" or "mixed infusions") were left out of the model.

Ingestion of high Cu doses induces acute effects in the gastrointestinal tract, mainly in the stomach (Furukawa and Hatano 1998; Kayashima et al. 1978; Niijima et al. 1987; Wang and Borison 1951), whereas chronic effects from long-term overexposure results mainly on Cu accumulation in the liver and liver damage (Bremmer 1998).

Confirming this hypothesis, Figure 9a,b demonstrates a reduction in nucleation density of h-BN on Cu by dosing 1 × 10 4 mbar of air after annealing in hydrogen and before borazine exposure, i.e., between steps 2 and 4. In the case of air-dosing, the nucleation density is reduced by an order of magnitude compared to the standard oxygen-free growth conditions.

(PDF 35 KB) 11671_2011_558_MOESM4_ESM.PDF Additional file 4: In vitro toxicity for comparison of Cu in CuCNPs versus similar dosing of free Cu OAc) 2. graph showing copper contained in nanoparticles was more toxic than an equivalent amount of copper dosed as a free complex.

A binary mixture of low-dose Cd (9 µmol L−1) and high-dose Cu (900 µmol L−1) showed toxicity to the seedlings, indicated by the significant augmentation in leaf malondialdehyde (MDA) and reduction in leaf chlorophylls.

First, the authors acknowledged that there are large data gaps on the toxicity of Cu at many doses.
