Abstract:
... Dielectric barrier discharge (DBD) cold plasma, as a new nonthermal technology, has attracted increasing attention in pesticide degradation. In this study, DBD plasma was used to degrade carbendazim (MBC) in aqueous solution. Under the optimal conditions (160 kv, 50 Hz), MBC solution (0.5 μg/mL) was degraded by 89.04% after plasma treatment for 10 min. Four MBC degradation products were identified ...

Abstract:
... Poor growth greatly reduces the production efficiency of small sea cucumbers Apostichopus japonicus in summer. The present study found that crawling frequency and tentacle activity frequency of sea cucumbers (~1 g of wet body weight) were significantly lower at 25 °C than those at 16 °C. These results suggest that high temperature greatly decreases fitness-related behavior of small A. japonicus. S ...

Abstract:
... In Arabidopsis thaliana, NAC-like and activated by AP3/PI (NAP) are NAC transcription factors that regulate leaf senescence and environment stress. Gene LbNAP, which has a typical NAC region, was cloned from lily petals. Our results indicated that LbNAP was located in the nucleus, and the gene had transcriptional activation activity. Further studies on LbNAP expression showed that it was lowest in ...
... In this study, shell-core fibers were successfully prepared by using Eudragit S100 (ES100) and poly(vinyl alcohol) (PVA)/pectin (PEC) through coaxial electrospinning technology. The electrospun fiber was characterized by attenuated total reflectance-Fourier transform infrared spectroscopy (ATR-FTIR) and X-ray diffraction (XRD). Thermo-gravimetric analysis (TGA) showed that the coaxial electrospun ...

We cultured post-larval shrimp in four salinity treatment groups (SAL20 (control) = 20 ppt (parts per thousand), SAL10 = 10 ppt, SAL30 = 30 ppt, and SAL40 = 40 ppt) for 20 days (restriction stage) and then transferred them to the control salinity environment (20 ppt) for 20 days (compensation stage). The SAL40 group exhibited an over-compensation growth effect in body length and weight, and the SA ...

Abstract:
... The large yellow croaker (Larimichthys crocea) is an economically important marine species with the highest annual production among the farmed marine fishes in China. However, the aquaculture industry of this species is suffering from severe problems that include weakened disease resistance, decreased growth rate, and reduced meat quality due to frequent inbreeding. Genome editing, which has a hug ...

Abstract:
... Feeding regime, which involve selection of appropriate diet and application of feed itself is a decisive factor in intensive, RAS-based production system – more so, for carnivorous fish culture. It is critical for the economics, resource (feed/nutrients) use efficiency and final profit yield. The present study examined different feeding strategies in juvenile pikeperch reared in RAS for growth per ...
... The increase in temperature due to global warming greatly affects the toxicity produced by pesticides in the aquatic ecosystem. Studies investigating the effects of such environmental stress factors on next generations are important in terms of the sustainability of ecosystems. In this study, the effects of parental synergistic exposure to glyphosate and temperature increase on the next generation ...
