Abstract Insecticidal bacterial proteins play key roles in insect-bacteria interactions and have been used as biopesticides. Here, we identify two insecticidal proteins in Paeniclostridium ghonii, designated PG-toxin 1 (PG1) and PG-toxin 2 (PG2), which are homologs of botulinum neurotoxins (BoNTs). Unlike BoNTs, PG1 and PG2 contain two separate proteins: One is the protease light chain (LC), and the other is the heavy chain containing the translocation domain and the receptor binding domain.

Abstract Salidroside (SAL) is the major ingredient of Rhodiola rosea, and has been traditionally used in Chinese medicine for decades. Numerous studies have demonstrated the protective effects of SAL for myocardial ischemia. However, it is yet to be deciphered whether SAL has cardioprotective effects after myocardial infarction (MI) in vivo. In the present study, we established a mouse MI model via coronary artery ligation.
