The Development of Peptide-based Antimicrobial Agents against Dengue Virus.

Dengue fever has become an imminent threat to international public health because of global warming and climate change. The World Health Organization proclaimed that more than 50% of the world's population is at risk of dengue virus (DENV) infection. Therefore, developing a clinically approved vaccine and effective therapeutic remedy for treating dengue fever is imperative.

Drug delivery systems and combination therapy by using vinca alkaloids.

Developing new methods for chemotherapy drug delivery has become a topic of great concern. Vinca alkaloids are among the most widely used chemotherapy reagents for tumor therapy; however, their side effects are particularly problematic for many medical doctors. To reduce the toxicity and enhance the therapeutic efficiency of vinca alkaloids, many researchers have developed strategies such as using liposome-entrapped drugs, chemical- or peptide-modified drugs, polymeric packaging drugs, and chemotherapy drug combinations.

Structures of two elapid snake venom metalloproteases with distinct activities highlight the disulfide patterns in the D domain of ADAMalysin family proteins.

The structures of snake venom metalloproteases (SVMPs) are proposed to be useful models to understand the structural and functional relationship of ADAM (a disintegrin and metalloprotease) which are membrane-anchored proteins involved in multiple human diseases. We have purified, sequenced and determined the structures of two new P-III SVMPs - atragin and kaouthiagin-like (K-like) from Naja atra. Atragin exhibits a known C-shaped topology, whereas K-like adopts an I-shaped conformation because of the distinct disulfide pattern in the disintegrin-like (D) domain.

Regenerative thermal oxidation of airborne N, N-dimethylformamide and its associated nitrogen oxides formation characteristics.

In this study, a two-bed electrically heated regenerative thermal oxidizer (RTO) was used to test the thermal destruction and oxides of nitrogen (NOx) formation characteristics in burning airstreams that contain either N, N-dimethylformamide or dimethylformamide (DMF) mixed with methyl ethyl ketone (MEK). The RTO contained two 0.152 m x 0.
