Piscirickettsia salmonis Produces a N-Acetyl-L-Homoserine Lactone as a Bacterial Quorum Sensing System-Related Molecule

open access: yesFrontiers in Cellular and Infection Microbiology, 2021
Piscirickettsia salmonis is the etiological agent of piscirickettsiosis, the most prevalent disease in salmonid species in Chilean salmonids farms. Many bacteria produce N-acyl-homoserine lactones (AHLs) as a quorum-sensing signal molecule to regulate ...

Trained Memory of Uterine Macrophages Improves Subsequent Pregnancy Outcomes

open access: yesAdvanced Science, EarlyView.
This study identifies that pregnancy imprints a durable, pregnancy‐specific form of trained immune memory in uterine macrophages, marked by the emergence of LILRB3+/PIR‐B+ cells that expand across gestations, acquire a tolerogenic and metabolically rewired phenotype, and actively protect against inflammatory pregnancy loss in mice.

AHL AL HADITS DAN AHL AL RA’YI

open access: yesJurnal Res Justitia: Jurnal Ilmu Hukum
This research discusses two main schools of thought in the development of Islamic law, namely Ahl al-Hadith and Ahl al-Ra'yi, which were prominent in the early period of the formation of fiqh. Ahl al-Hadith emphasizes the importance of the authority of Islamic texts, especially the Koran and hadith, in establishing law.

Detection of New Quorum Sensing N-Acyl Homoserine Lactones From Aeromonas veronii

open access: yesFrontiers in Microbiology, 2018
Sturgeon is an important fresh water-culture fish in China. A problem with sturgeon is its high susceptibility to spoilage. Food spoilage is reported to be regulated by quorum sensing (QS). To identify the QS signals acetylated homoserine lactones (AHLs)
