Campylobacter jejuni enterotoxin was partially purified from culture supernatant. The purified fraction after gel filtration indicated three bands at 68, 54, and 43 kilodaltons on sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE). This fraction enhanced the adenylate cyclase activity of HeLa cell membranes by 1.5-fold over that of the control. The study with anti-cholera toxi...

  Background: The purity and correct folding of a recombinant protein is critical for any structural, biochemical and vaccine design studies. Plasmodium vivax Duffy binding protein-II is a leading vaccine candidate for vivax malaria. In the present study, the purification process of recombinant DBP-IX (a variant form of PvDBP-II) was optimized to achieve the highest yield and purity. Moreover, ...

This chapter analyzes the adequacy of two university education models according to their Information Communications Technology (ICT) usage: One model is based on the use of ICT as a cornerstone and a cohesive element of the teaching-learning process, whereas the other considers ICT a mere teaching support tool. The preliminary results obtained from a review of case studies reveal that ICT use i...
