Identification of atypical T4SS effector proteins mediating bacterial defense
mLife, Volume 2, Issue 3, Page 295-307, September 2023., 2023 Abstract To remain competitive, proteobacteria use various contact‐dependent weapon systems to defend against microbial competitors. The bacterial‐killing type IV secretion system (T4SS) is one such powerful weapon. It commonly controls the killing/competition between species by secreting the lethal T4SS effector (T4E) proteins carrying conserved ...

An Antifungal Polycyclic Tetramate Macrolactam, Heat-Stable Antifungal Factor (HSAF), Is a Novel Oxidative Stress Modulator in Lysobacter enzymogenes. [PDF]
Appl Environ Microbiol, 2021 PoTeMs are a family of structurally distinct metabolites that have been found in a large number of bacteria. Although PoTeMs exhibit diverse therapeutic properties, the physiological function of PoTeMs in the producer microorganisms had not been investigated.

Interoperability among hospitals treating populations that have been marginalized
Health Services Research, Volume 58, Issue 4, Page 853-864, August 2023., 2023 Abstract Objective To test whether differences in hospital interoperability are related to the extent to which hospitals treat groups that have been economically and socially marginalized. Data Sources and Study Setting Data on 2393 non‐federal acute care hospitals in the United States from the American Hospital Association Information Technology ...

Journal of Geophysical Research: Biogeosciences, Volume 128, Issue 7, July 2023., 2023 Abstract Contrary to the general “greening of the Arctic”, the Siberian Indigirka Lowlands show strong “browning” (a decrease in the Normalized Difference Vegetation Index or “NDVI”) in various recent satellite records. Since greening and browning are generally indicative of increases and losses in photosynthetically active biomass, this browning trend

Advanced Science, Volume 9, Issue 11, April 14, 2022., 2022 This review proposes a novel concept to construct bone repair biomaterials based on supramolecular peptide nanofiber hydrogels, namely multihierarchical fabrications by structural design, biochemical functionalization, and mechanical optimization. Then, it discusses the comprehensive applications of supramolecular peptide nanofiber hydrogels for bone ...

Molecular Plant Pathology, Volume 22, Issue 5, Page 602-617, May 2021., 2021 PilR phosphorylation mediated by PilS down‐regulates lchD expression via DNA binding to lower c‐di‐GMP synthesis and thus accumulate c‐di‐GMP‐free Clp, which activates heat‐stable antifungal factor production via DNA binding. Abstract In the soil gammaproteobacterium Lysobacter enzymogenes, a natural fungal predator, the response regulator PilR ...

Functionalized peptide hydrogels as tunable extracellular matrix mimics for biological applications
Peptide Science, Volume 113, Issue 2, March 2021., 2021 Abstract The development of tailorable and biocompatible three‐dimensional (3D) substrates or molecular networks that reliably mimic the extracellular matrix (ECM) and influence cell behavior and growth in vitro is of increasing interest for cell‐based applications in the field of tissue engineering and regenerative medicine.

Control of glucosylceramide production and morphogenesis by the Bar1 ceramide synthase in Fusarium graminearum. [PDF]
PLoS ONE, 2011 The contribution of plasma membrane proteins to the virulence of plant pathogenic fungi is poorly understood. Accordingly, the objective of this study was to characterize the acyl-CoA dependent ceramide synthase Bar1 (previously implicated in plasma ...
