Perylene diimide based fluorescent sensors for aqueous detection of perfluorooctane sulfonate (PFOS).

Background: Perfluorooctane sulfonate (PFOS), one of the most harmful members of the large group of per- and poly-fluoroalkyl substances (PFAS), is notorious for its environmental persistence, bioaccumulation, and toxic effects, raising serious environmental and health concerns. Developing rapid and sensitive methods to detect PFOS in water is critical for effective monitoring and protection against this hazardous chemical.

Results: In this study, we developed rapid and highly sensitive fluorometric sensors (PDI-2+ , PDI-6+ ) for detecting PFOS.

Challenges in Geographic Access to Specialized Pediatric Burn Care in the United States.

Background: Geographical access to pediatric burn centers in the US is not well described. Patients may receive care at American Burn Association (ABA)-verified burn centers, unverified burn centers, or non-burn centers. A recent study indicated that most US counties do not have an ABA-verified pediatric burn center within 100 miles.

Complete genome sequence of bacteriophage Godfather isolated from .

Microbacteriophage Godfather was collected from a soil sample in Stephenville, Texas. The 17,452-bp double-stranded genome contains 24 protein-coding genes. The genome shares >99% nucleotide sequence identity with cluster EE microbacteriophages Scamander, Danno, Kojax4, and Burgy.

A sensitivity analysis of methodological variables associated with microbiome measurements.

The experimental methods employed during metagenomic sequencing analyses of microbiome samples significantly impact the resulting data and typically vary substantially between laboratories. In this study, a full factorial experimental design was used to compare the effects of a select set of methodological choices (sample, operator, lot, extraction kit, variable region, and reference database) on the analysis of biologically diverse stool samples. For each parameter investigated, a main effect was calculated that allowed direct comparison both between methodological choices (bias effects) and between samples (real biological differences).
