Japanese chum salmon stock enhancement: current perspective and future challenges

from Chum Salmon

Cystatin, a cysteine proteinase inhibitor, was isolated from chum salmon (Oncorilynch"s keta) pituitary glands by ion-exchange chromatography on Mono-Q, gel filtration on Superdex 75, and reverse-phase HPLC on an ODS fo1]owing ethanol-ammonium acetate extraction. Salmon pituitary cystatin was equipotent te chicken egg-white cystatin in the papain inhibitory assay. The cystatin consists of 111 a...

Down Syndrome: Current Status, Challenges and Future Perspectives

RNAi for insect control: current perspective and future challenges.

The research on the RNA interference (RNAi) for the control of insect pests has made significant growth in recent years. The availability of the genomic sequences of insects has further widened the horizons for the testing of this technology to various insect groups. Different modes of application of double-stranded RNA (dsRNA) have been tested; however, the practicability of delivery of dsRNA ...

Current Diagnostic Status of Pheochromocytomaand Future Perspective: A Mini Review

Pheochromocytomas (PCCs) are rare neuroendocrine tumors. The current diagnostic tools are based on biochemistry and histopathology results, but heterogeneity of diagnostic markers, signs and symptoms of PCCs bring a lot of difficulties for these two current methods. Unfortunately microscopic understanding of PCCs is not adequate for its confident prognosis and management. There are data linking...
