Bisphenol B Exposure Induces Miscarriage by Suppressing Migration/Invasion and Migrasome Formation

open access: yesAdvanced Science, EarlyView.
BPB (Bisphenol B) exposure up‐regulates ER (estrogen receptor) levels, enhances its interactions with the lnc‐HZ04 promoter region, and thus promotes ER‐mediated lnc‐HZ04 transcription. Subsequently, lnc‐HZ04 suppresses TCF4 (transcription factor 4)‐mediated PKCA (protein kinase C alpha) transcription and subsequently suppresses migration/invasion and ...

Research, monitoring, and reflection as a guide to the management of complex ecosystems: The case of fire in the Kruger National Park, South Africa

open access: yesConservation Science and Practice, 2022
Conservation managers frequently set goals and monitor progress toward them. This often becomes a routine annual exercise, and periodic reflection over longer periods is done less often, if at all.
