Understanding the complex nature of endodontic biofilm would help to create a new disinfection strategy to eliminate the microorganism from the root canal system. The intricate canal structure creates challenges for proper disinfection, necessitating the need to understand the biofilm structure, composition, and mechanism within the biofilm community.

The Wnt-dependent master regulator NKX1-2 controls mouse pre-implantation development.

Embryo size, specification, and homeostasis are regulated by a complex gene regulatory and signaling network. Here we used gene expression signatures of Wnt-activated mouse embryonic stem cell (mESC) clones to reverse engineer an mESC regulatory network. We identify NKX1-2 as a novel master regulator of preimplantation embryo development.

EMBRACE (Empowering Medical students' skills in BReaking bAd news with Compassion and Empathy) module improves the skills of undergraduate medical students in effectively breaking the bad news: a case-control study.

A new ferrocene derivative blocks KRAS localization and function by oxidative modification at His95.

Ras proteins are membrane-bound GTPases that regulate essential cellular processes at the plasma membrane (PM). Constitutively active mutations of K-Ras, one of the three Ras isoforms in mammalian cells, are frequently found in human cancers. Ferrocene derivatives, which elevate cellular reactive oxygen species (ROS), have shown to block the growth of non-small cell lung cancers (NSCLCs) harboring oncogenic mutant K-Ras.

Controlling anammox speciation and biofilm attachment strategy using N-biotransformation intermediates and organic carbon levels.

Conventional nitrogen removal in wastewater treatment requires a high oxygen and energy input. Anaerobic ammonium oxidation (anammox), the single-step conversion of ammonium and nitrite to nitrogen gas, is a more energy and cost effective alternative applied extensively to sidestream wastewater treatment. It would also be a mainstream treatment option if species diversity and physiology were better understood.
