A central concern of media scholars such as Ben Bagdikian and Robert McChesney is the undemocratic potential of the U.S. mainstream media system, dominated by a small number of highly consolidated, multinational, corporate media firms. In this context, other scholars, including Chris Atton, John Downing, Stephen Duncombe, Nina Eliasoph, and Clemencia Rodriguez, have argued for the importance of...

Background The large-scale production of biopharmaceuticals, such as monoclonal antibodies (mAbs), commonly requires the use of serum-free medium, for both safety and economical reasons. However, because serum is such an essential supplement of the growth medium of most mammalian cells, its removal demands a very time-consuming process of cell adaptation. In this process, cells are usually subj...

One of the basic postulates of molecular evolution is that functionally important genes should evolve slower than genes of lesser significance. Essential genes, whose knockout leads to a lethal phenotype are considered of high functional importance, yet whether they are truly more conserved than nonessential genes has been the topic of much debate, fuelled by a host of contradictory findings. H...

Recent national and international developments are demonstrating the power of technology to transform communication channels, media sources, events, and the fundamental nature of journalism. Technological advances now allow citizens to record and instantly publicize information and images for immediate distribution on ubiquitous communication networks using social media such as Twitter, Faceboo...

Silk protein sericins, in the recent years, find application in cosmetics and pharmaceuticals and as biomaterials. We investigate the potential of sericin, extracted from both mulberry Bombyx mori and different non-mulberry sources, namely, tropical tasar, Antheraea mylitta; muga, Antheraea assama; and eri, Samia ricini, as growth supplement in serum-free culture medium. Sericin supplemented me...

The complex formation between allylamine and mineral acids (HCl, H 2 SO 4, 3 PO 4 ) their stabilities were investigated by Uv-Vis, DSC TGA analyses. Free radical polymerization of salts was achieved using 2,2?-azobis (2-methylpropanediamine)dihydrochloride at 50 o C under N atmosphere in water. PAlAm synthesized the presence insoluble water due to physical crosslinking chains. They converted so...
