Formaldehyde quantification using ampicillin is not selective [PDF]

Formaldehyde (HCHO) is a simple and highly reactive human metabolite but its biochemistry is poorly defined. A limiting factor in HCHO research is lack of validated quantification methods for HCHO relevant to biological samples. We describe spectroscopic

Ester prodrugs of ampicillin tailored for intracellular accumulation

, 1997
Seven new ester prodrugs of ampicillin with hydrolysis half-lives ranging from 65 to 308 min were synthesized. The cellular accumulation of two of them (in J774 mouse macrophages) and their activities against intracellular Staphylococcus aureus were ...

The expansion of culturable opportunistic pathogens and antibiotic resistance in mouse gut following antibiotic exposure

Microbiology Spectrum
Antibiotics significantly change gut microbiota, leading to dysbiosis and changes in bacterial community composition, which further results in a series of dysfunctions with severe health consequences.

Pharmacokinetic Comparison of Oral Bacampicillin and Ampicillin

, 1984
Bacampicillin is a oral prodrug which is rapidly 'Converted to ampicillin during absorption from the gastrointestinal tract. It is much more lipophilic than ampicillin by the substitution at the ampicillin thia' zolidine carboxy group.

Optimized Selenium‐Doped Nanocomposites for Enhanced Polymer Gel Performance in Permeability Reduction

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Excessive water production in mature oil fields necessitates robust shut‐off treatments, yet conventional polymer gels often fail under high‐temperature and high‐salinity conditions. This study aims to enhance gel thermal stability and mechanical strength by incorporating selenium‐doped Ag/AgO–ZnO nanocomposites synthesized via a novel green ...

Synergistic Advanced Oxidation and Physicochemical Treatment Strategies for Antibiotic Removal and Resistance Mitigation in Water

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT The presence of antibiotics in water not only causes environmental pollution but also increases the growth of antibiotic‐resistant bacterial genes, which pose serious threats to human beings and other water residents. Large numbers of people are reportedly affected by the resistant bacterial genes, as many broad‐spectrum antibiotics are not ...

Emergence of ampicillin-resistant Enterococcus faecium in Danish hospitals

, 2008
BACKGROUND: Ampicillin-resistant Enterococcus faecium isolates are reported in increasing numbers in many European hospitals. The clonal complex 17 (CC17) characterized by ampicillin resistance has been associated with nosocomial E. faecium outbreaks and

Exploring the Roles of Tuna‐Associated Acinetobacter sp. YFT067: Implications for Host Health and Metabolism

Animal Research and One Health, EarlyView.
This study firstly isolated a tuna‐derived gut probiotic Acinetobacter seifertii YFT067. Dietary administration of YFT067 played significant roles in promoting growth performance, SCFAs production, lipid absorption, and metabolism of the host, indicating YFT067 as a promising probiotic candidate for enhancing tuna aquaculture productivity through ...

Evaluation of a Product Intended for Microbiological Control in Animal Production, and Its Combination With Halquinol

Animal Research and One Health, EarlyView.
Activo Liquid and Halquinol inhibit Salmonella and Escherichia coli in culture media. Activo Liquid exhibits bactericidal action, whereas HA is bacteriostatic, and their combination results in positive or indifferent interactions. This combination effectively inhibits E. coli throughout digestion simulation, thus reducing the required concentrations of
