Mild hypothermia upregulates myc and xbp1s expression and improves anti-TNFα production in CHO cells
Chinese hamster ovary (CHO) cells are the most frequently used host for commercial production of therapeutic proteins. However, their low protein productivity in culture is the main hurdle to overcome. Mild hypothermia has been established as an effective strategy to enhance protein specific productivity, although the causes of such improvement still remain unclear. The self-regulation of globa...
BACKGROUND The role of surgery in the treatment of non-small-cell lung cancer (NSCLC) with clinically manifested mediastinal node metastasis is controversial even in resectable cases because it is often accompanied by systemic micrometastasis. However, surgery is occasionally indicated for cases with single-station N2 disease or within multimodal treatment regimens, and in clinical trials. The ...
In this paper we present a robust information integration approach to identifying images of persons in large collections, such as the web. The underlying system relies on combining content analysis, which involves face detection and recognition, with context analysis which involves extraction of text or HTML features. Two aspects are explored to test the robustness of this approach: Sensitivity...
The refractive index structure constant Cn2 near the ocean surface is an important parameter for studying atmospheric optical turbulence over ocean. measured and meteorological parameters, such as temperature three-dimensional wind speed, sea on South China Sea during period from January to November 2020 were analyzed. On basis of Monin–Obukhov similarity theory, dimensionless function fT was e...
Within the vertebrate eye, bc crystallins are extremely stable lens proteins that are uniquely adapted to increase refractory power while maintaining transparency. Unlike a crystallins, which are well-characterized, multifunctional proteins that have important functions both in and out of the lens, bc lens crystallins are a diverse group of proteins with no clear ancestral or contemporary nonle...
