A Circular and Tacticity‐Independent Crystalline Mono‐Substituted Nylon‐6 Platform: Unexpected Large Positional Effects on Crystallizability and Performance

open access: yesAngewandte Chemie, EarlyView.
Methyl substitution positions on the nylon‐6 backbone markedly affect crystallizability, thermomechanical properties, and recyclability of the resulting atactic nylon‐6 variants. While γ‐methyl substitution gives an amorphous nylon, all other four methyl‐substitution positions (α, β, δ, and ε) afford, unexpectedly, crystalline nylons, showing tacticity‐

Targeting Peptostreptococcus anaerobius with an Iron‐Based Nanozyme Reverses Ferroptosis Resistance and Enhances Antitumor Immunity in Colorectal Cancer

open access: yesAdvanced Science, EarlyView.
An iron‐based nanozyme selectively eliminates intratumoral P. anaerobius while catalytically generating ROS to induce ferroptosis, synergistically suppressing colorectal cancer growth and activating anti‐tumor immunity through immunogenic cell death. ABSTRACT The intratumoral microbiota is a critical determinant of therapeutic outcomes in colorectal ...

Diversity of Pharmaceuticals Enhances Antibiotic Resistance in the Invertebrate Gut via Biofilm‐Mediated Mechanisms

open access: yesAdvanced Science, EarlyView.
Pharmaceutical diversity acts as an independent driver of antibiotic resistance in soil invertebrates. While bulk soil remains unaffected, the collembolan gut microbiome exhibits significant resistance gene enrichment under complex chemical exposure and diurnal warming.

Stress History Establishes a Transient Tolerant State That Shapes Antibiotic Survival Upon Resuscitation

open access: yesAdvanced Science, EarlyView.
High‐throughput single‐cell analysis of resuscitating bacteria reveals a starvation‐history‐dependent transiently tolerant subpopulation that survives β$\beta$‐lactam exposure by temporarily reducing growth. Distinct from classical persisters, these actively growing yet dynamically modulated cells dominate survival across clinically relevant antibiotic

Antibiotic stewardship implementation and patient-level antibiotic use at hospitals with and without on-site Infectious Disease specialists. [PDF]

open access: yes, 2020
Many US hospitals lack Infectious Disease (ID) specialists, which may hinder antibiotic stewardship efforts. We sought to compare patient-level antibiotic exposure at Veterans Health Administration (VHA) hospitals with and without an on-site ID ...

Utility of beta-lactam allergy assessment in patients receiving vancomycin for surgical prophylaxis

open access: yesSurgery in Practice and Science
Background: Beta-lactam antibiotics are first-line agents for most patients receiving antimicrobial prophylaxis in surgical procedures. Despite evidence showing low cross-reactivity between penicillins and cephalosporins, patients with beta-lactam ...

Ethane-beta-Sultam Modifies the Activation of the Innate Immune System Induced by Intermittent Ethanol Administration in Female Adolescent Rats [PDF]

open access: yes, 2014
Intermittent ethanol abuse or ‘binge drinking’ during adolescence induces neuronal damage, which may be associated with cognitive dysfunction. To investigate the neurochemical processes involved, rats were administered either 1 g/kg or 2 g/kg ethanol in ...
