Sulfur dioxide enhance drought tolerance of wheat seedlings through HS signaling.

Drought is one of the most common factors that limit plant growth and productivity. Sulfur dioxide (SO) has recently been found to play a benefical role in protection of plants against environmental stress. In this study, we investigated the effect of SO on the physiological and molecular response of wheat seedlings to drought stress.

Effect of acute ammonia exposure on the glutathione redox system in FFRC strain common carp (Cyprinus carpio L.).

Ammonia is one of the most common aquatic pollutants. To analyze the effect of ammonia exposure on the glutathione redox system, we investigated the levels of hydrogen peroxide (HO) and glutathione, and transcription and activities of glutathione-related enzymes in liver and gills of FFRC strain common carp (Cyprinus carpio L.) exposed to 0, 10, 20, and 30 mg/L of ammonia.

Integrated sediment quality assessment through biomarker responses and bioavailability measurements: Application in Tai Lake, China.

A weight of evidence (WoE) framework has been applied to assess sediment quality of a typical freshwater lake, Tai Lake in China, where the sediments were contaminated by various chemicals but showed no acute lethality to the benthic invertebrate, Chironomus dilutus. A quantitative scoring method was employed to integrate three lines of evidence (LoE), including adverse effects in life cycle bioassays, biomarker responses, and bioavailability-based chemical analysis. Six biomarkers were determined in C.

Joint toxicity of sediment-associated DDT and copper to a polychaete, Nereis succinea.

As major components in antifouling paints, both dichlorodiphenyltrichloroethane (DDT) and copper are ubiquitous in estuarine sediment and have been detected at high concentrations in the harbors in South China. In the present study joint toxicity between DDT and copper to an estuarine polychaete, Nereis succinea, was examined using bioaccumulation potential, growth impairment and change in lipid peroxidation contents as sub-lethal endpoints. In general, the toxicity of DDXs (DDT and its metabolites) and copper acted independently and copper was more toxic to the lugworms at environmentally relevant concentrations.

Assessment of the estrogenic activities of chickpea (Cicer arietinum L) sprout isoflavone extract in ovariectomized rats.

Aim: Chickpea (Cicer arietinum L) is a traditional Uighur herb. In this study we investigated the estrogenic activities of the isoflavones extracted from chickpea sprouts (ICS) in ovariectomized rats.

Methods: Ten-week-old virgin Sprague-Dawley female rats were ovariectomized (OVX).
