Discovery of structural and functional transition sites for membrane-penetrating activity of sheep myeloid antimicrobial peptide-18

Scientific Reports, 2023
Cathelicidin antimicrobial peptides have an extended and/or unstructured conformation in aqueous solutions but fold into ordered conformations, such as the α-helical structure, when interacting with cellular membranes. These structural transitions can be

Oxaziridines: Versatile Reagents in Modern Organic Synthesis

The Chemical Record, EarlyView.
Being capable of transferring an O atom and N‐group/atom, oxaziridines are considered multitasking agents. These are employed for diverse organic transformations, such as epoxidation of olefins, α‐ and γ‐hydroxylation/amination of carbonyl compounds, oxidation of sulfides, [3+2]cycloaddition with unsaturated systems.

Evaluation of the Adequate Radiopacity of Cavity Lining/Base and Core Build‐Up Light Cured Composite Resins

Australian Dental Journal, EarlyView.
ABSTRACT Background This study aimed to compare the radiopacity of composite resins (CR) used as lining, base, and core‐build up materials with enamel and dentine and evaluate their compliance with ISO 4049. Methods Specimens of 1, 2, and 3 mm thicknesses; (n = 6) were fabricated from 13 low‐viscosity and 10 regular‐viscosity CRs.

Validation of SMAP Soil Moisture at Terrestrial National Ecological Observatory Network (NEON) Sites Show Potential for Soil Moisture Retrieval in Forested Areas

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2021
Soil moisture influences forest health, fire occurrence and extent, and insect and pathogen impacts, creating a need for regular, globally extensive soil moisture measurements that can only be achieved by satellite-based sensors, such as NASA's ...

Presynaptic actin nanostructures: A reproducibility case study

Journal of Microscopy, EarlyView.
Abstract In an effort to assess the reproducibility of bioimage analyses in current publications, we took part in a Global BioImage Analysts’ Society (GloBIAS) initiative to try and reproduce results from published articles. We attempted to reproduce core findings from Bingham et al.

Biocrust restoration in novel climates: assisted migration, habitat amelioration, and varied community composition as climate‐smart techniques

Restoration Ecology, EarlyView.
Abstract Introduction Successful restoration of terrestrial drylands depends on stable, fertile soils that retain water. These functions are provided by biological soil crusts (biocrust), suggesting their reestablishment is a critical step in dryland restoration.
