The study presented here was conducted to evaluate the performance of a double-antigen sandwich ELISA to detect antibodies in human serum against the coronavirus associated with severe acute respiratory syndrome (SARS). A recombinant partial nucleocapsid protein of SARS-associated coronavirus was used as a serodiagnostic antigen in the ELISA. A total of 2892 clinical serum samples were tested with the ELISA kit, which positively identified 25 of 35 (71.4%) samples of patients with confirmed SARS infection, 286 of 407 (70%) samples of patients suspected of having SARS, 229 of 302 (75.8%) samples of convalescent SARS patients, and 0 of 544 samples obtained from healthcare workers; only 1 of 1604 clinical samples obtained from patients with other diseases demonstrated a weakly positive result. These results indicate that the double-antigen sandwich ELISA is an effective screening method for the serodiagnosis of SARS-associated coronavirus.

Background:The prevalence of Type 2 Diabetes Mellitus (T2DM) continues to rise globally. The T2DM prevalence is not only in developing countries, but also in developed countries now. Correspondingly, the therapeutics of T2DM calls for a change (higher efficiency) due to growing number of patients and increasing economic burdens globally. Entering into this millennium, both piecemeal pathways (idea driven) and exponential growth of human genomic study are developing quickly. Genetypic-phenotypic translation, modern diagnostics, pharmacology, drug developments, traditional Chinese medicine, personalized medicine and so on are promising disciplines for this change. The clinical anti-diabetic therapeutics, pathogenesis, drug development pipelines are especially highlighted.Conclusion:In summary, a general landscape and principle of T2DM is provided.
