Acute Toxicity of Gamma Radiation to the Monogonont Rotifer Brachionus koreanus
We examined the tolerance of the monogonont rotifer Brachionus koreanus in response to gamma radiation. In order to determine the median lethal dose (LD50) of rotifers against gamma radiation, we irradiated B. ko...

Identification of insulin-like peptide 1 (ILP1) gene and its expression in response to different food sources in the intertidal copepod Tigriopus japonicus
Insulin-like peptide (ILP) is an important hormone that controls a wide array of functions including glucose or trehalose levels in body fluids in invertebrates. However, the presence and role of ILP in copepo...

Combined effects of cadmium and copper on the expression of antioxidant enzyme — coding genes in the polychaete, Perinereis nuntia
Polychaetes have been used as useful model organisms for environmental pollution monitoring in aquatic sediments. Here, we investigated the combined effect of copper (50, 100 and 200 μg/L) and cadmium (50 μg/L...

Evaluation of the potential impact of polluted sediments using Manila clam Ruditapes philippinarum: bioaccumulation and biomarker responses
An assessment was made to monitor the short-term impact of heavily polluted sediments that may move out from the brackish man-made Lake Shihwa outside of the sea dike due to operations of a tidal power plant. ...

Molecular cloning and expression of novel metallothionein (MT) gene in the polychaete Perinereis nuntia exposed to metals
To report a novel metallothionein (MT) gene and evaluate its potency as a biomarker, we clone this MT gene and measured the expression levels in the metal-exposed polychaete Perinereis nuntia. Accumulated metal c...
