Effects of 0.4 T, 3.0 T and 9.4 T static magnetic fields on development, behaviour and immune response in zebrafish (Danio rerio).

Magnetic Resonance Imaging (MRI) is widely applied in medical diagnosis due to its excellent non-invasiveness. With the increasing intensity of static magnetic field (SMF), the safety assessment of MRI has been ongoing. In this study, zebrafish larvae were exposed to SMFs of 0.

The influences and regulatory mechanisms of magnetic fields on circadian rhythms.

A variety of devices used in daily life and biomedical field will generate magnetic fields with different parameters, raising concern about their influences on people's physiological functions. Multiple experimental works have been devoted to the influences of magnetic fields on circadian rhythms, yet the findings were not always consistent due to the differences in magnetic field parameters and experimental organisms. Also, clear regulatory mechanisms have not been found.

Cordycepin inhibits inflammatory responses through suppression of ERK activation in zebrafish.

As a natural extract, cordycepin has been shown to play important regulatory roles in many life activities. In the study, the effects of cordycepin on inflammatory responses and the underlying mechanisms was explored using a zebrafish model. In the model of LPS-induced inflammation, cordycepin was found to significantly inhibited the expression of pro-inflammatory cytokines such as tnf-α, il-1β, il-6, and il-8.

[Effects of simulated elevation of atmospheric CO2 concentration on the physiological features of spring phytoplankton in Taihu Lake].

To disclose the impact of different CO2 concentrations (270 x 10(-6), 380 x 10(-6), 750 x 10(-6)) on physiological features of spring phytoplankton, an in situ simulated experiment was carried out in Meiliang Bay of Taihu Lake from 29 April to 26 May in 2012. The results showed that atmospheric CO2 elevation would significantly alter the pH value and carbonate chemical environments of Taihu Lake, resulting in weakening the advantages of carbon concentrating mechanism (CCM) of phytoplankton. Phytoplankton in Taihu Lake tended to use more dissolved CO2 (CO2, aq) due to the deliberate CO2 sequestration under the high CO2 level treatment.
