Abstract:
... Traditional phenolic resin binder is prepared by chemical catalysis of toxic fossil raw materials with toxic wastewater produced in the process. The pyrotechnic with phenolic resin as binder cannot be fully burned, resulting in particulate matter pollution, which is harmful to human body and pollutes the environment. In this study, a new polyester pyrotechnic binder (Mn = 2834 g/mol, PDI = 1.22) w ...

Abstract:
... Envelope proteins of white spot syndrome virus (WSSV) play an important role in viral entry as well as in triggering host defences. To date, some main envelope proteins such as VP28, VP24 and VP19 have been expressed heterologously and proved effective in WSSV prevention. However, VP62, an envelope protein with hub function as well as better antigenicity, has not been focused on. In an attempt to ...

Abstract:
... Oral lichen planus (OLP) is a common T-cell-mediated immunological disease. Hypoxia-inducible factor 1 alpha (HIF1α) plays an integral role in the glycolytic metabolism that facilitates immune functions from boosting cellular proliferative capacity to driving T-cell differentiation. In general, phospholipase D2 (PLD2) is required for HIF1α regulation. However, the involvement of HIF1α and PLD2 in ...
