Microbiota-Produced N-Formyl Peptide fMLF Promotes Obesity-Induced Glucose Intolerance. [PDF]

open access: yes, 2019
The composition of the gastrointestinal microbiota and associated metabolites changes dramatically with diet and the development of obesity. Although many correlations have been described, specific mechanistic links between these changes and glucose ...

Adaptation to high ethanol reveals complex evolutionary pathways [PDF]

open access: yes, 2015
Tolerance to high levels of ethanol is an ecologically and industrially relevant phenotype of microbes, but the molecular mechanisms underlying this complex trait remain largely unknown.

A Biochar‐Based Composite Hydrogel Microenvironment for Enhanced Biocatalysis

open access: yesAdvanced Materials, EarlyView.
This work presents the synthesis of a polyacrylamide hydrogel wherein biomass‐derived biochar is co‐encapsulated with the enzyme horseradish peroxidase (HRP). The resulting composite hydrogel possesses balanced electron‐rich and electron‐deficient domains, creating an optimal microenvironment that concentrates both hydrogen peroxide and phenol ...

Tolerability of moxifloxacin in patients with antibiotic hypersensitivity

open access: yesAllergologia et Immunopathologia, 2005
Allergic reactions to antibiotics are commonly reported in the clinical practice. The treatment of antibiotic hypersensitivity (AH) consists of suggesting to avoid the offending antibiotics and to use safe alternatives after performing oral provocation tests (OPT). Moxifloxacin is a new fluoroquinolone antibacterial agent with a broad spectrum activity.

Nonmulberry Silk Fibroin Doping Boosts Charge Transfer and Charge Injection in Aligned Polypyrrole‐Silk Scaffolds for Low‐Voltage Neurostimulation

open access: yesAdvanced Materials Interfaces, EarlyView.
Conductive silk‐polypyrrole scaffolds couple redox stability with cell‐affinitive peptides present innately in an endogenous silk fibroin, enabling optimized electrical stimulation to drive neurite outgrowth. Findings establish electrochemical‐biological link for biomaterial design rules for smart nerve guidance conduits that can provide low voltage ...

Enhanced Infection Resistance and Regenerative Healing of Titanium Implants via Peptide‐Loaded Biodegradable Coatings

open access: yesAdvanced Materials Technologies, EarlyView.
This study presents a new biodegradable coating for titanium implants using a natural antimicrobial peptide, caerin 1.9. Applied via solvent casting, the coating offers sustained antibacterial protection and promotes healing. Tested on 3D‐printed porous titanium scaffolds, it effectively prevented infection—including against resistant bacteria—while ...

Resonant activation: a strategy against bacterial persistence

open access: yes, 2010
A bacterial colony may develop a small number of cells genetically identical to, but phenotypically different from other normally growing bacteria. These so-called persister cells keep themselves in a dormant state and thus are insensitive to antibiotic ...

Biofilm is a major virulence determinant in bacterial colonization of chronic skin ulcers independently from the multidrug resistant phenotype [PDF]

open access: yes, 2017
Bacterial biofilm is a major factor in delayed wound healing and high levels of biofilm production have been repeatedly described in multidrug resistant organisms (MDROs).

Autolysis Control Hypotheses for Tolerance to Wall Antibiotics [PDF]

open access: yesAntimicrobial Agents and Chemotherapy, 2001
Antibiotics are divided into two classes: bacteriostatic and bactericidal. The reasons for their classification are usually self-evident, although seldom proven. For example, chloramphenicol stops protein synthesis and is bacteriostatic, probably because when it is removed growth can recommence.
