is a member of the STAT protein family, and is mainly activated by the interleukin (IL)-6 family of cytokines, interferons, epidermal growth factor and leptin. Similar to other members of the STAT family, upon cytokine stimulation, STAT3 is tyrosine-phosphorylated at Tyr-705 by Janus kinases (Jaks), and is subsequently dimerized and translocated to the nucleus to activate its target genes. STAT...

This paper presents a tunable optofluidic prism based on the configuration of two laminar flow streams with different refractive indices in a triangular chamber. The chambers with 70 and 90 apex angles are designed based on simulation results, which provide the optimum working range and avoid recirculating flows in the chambers. In addition, a hydrodynamic model has been developed to predict th...

Taiping Rebellion, 1851–1864

The scenario was aggravated by the entry of western capitalism. From the beginning of the nineteenth century, the import of goods from abroad, especially opium, had risen steeply compared to exports. Thus the balance of trade went against China. The import hike was met by the export of large quantities of silver from China to other countries. Before the beginning of the nineteenth century, tael...
