Due to its malignancy, the development of effective therapeutic strategies for hepatocellular carcinoma (HCC) is of urgent needs. Natural antimicrobial peptides (AMPs), also known as host defense peptides (HDPs), not only act as direct antimicrobial agents, but also represent important

The use of molecular diagnostic tools in epidemiological investigations of Cryptosporidium, Giardia, and Enterocytozoon has provided new insights into their diversity and transmission pathways. In this study, 157 stool specimens from 2-month to 70-year-old patients were collected, a polymerase chain

Cereal yields decrease when grain fill proceeds under conditions of prolonged, moderately elevated temperatures. Endosperm-endogenous processes alter both rate and duration of dry weight gain, but underlying mechanisms remain unclear. Heat effects could be mediated by either abnormal, premature cessation

Nonribosomal peptide synthetases (NRPSs) produce many important and structurally complex natural products. Because of their architectures, reprogramming NRPSs has long been attempted to access new bioactive compounds. However, detailed characterization of NRPS catalysis and substrate selectivity by adenylation (A) domains
