Background: Based on the low volatility and refractory nature of Tetracycline (TC), excessive use leads to its continuous accumulation in water environments, posing serious risks to the ecological environment and human health. Although a very limited number of nanomaterials capable of simultaneously detecting and removing TC have been fabricated, they generally exist issues associated with a single detection signal ("on" or "off") or low adsorption rates with low adsorption capacities. As a result, it is crucial to develop a reliable technique to achieve ratiometric detection as well as rapid and efficient removal of TC.

Eravacycline is a broad-spectrum fluorocycline currently approved for complicated intra-abdominal infections (cIAIs). In lung-infection models, it is effective against methicillin-resistant (MRSA) and tetracycline-resistant MRSA. As such, we aimed to develop a population pharmacokinetic/pharmacodynamic (PK/PD) model to evaluate eravacycline's pulmonary distribution and kinetics.

The spread of multidrug-resistant (MDR) bacteria and their resistance genes along the food chain and the environment has become a global threat aggravated by incorrect disinfection strategies. This study analysed the effect of induction by sub-inhibitory concentrations of eugenol - a major ingredient in clove essential oil commonly used in disinfectant agents - on the phenotypic and genotypic response of MDR Enterococcus faecalis E9.8 strain, selected based on the phenotypic response of other enterococci.

This study explored the use of mango lignocellulosic kernel biochar (MKB) modified with MnFeO magnetic nanoparticles and a Cu@Zn-BDC metal-organic framework (MOF) (MKB/MnFeO/Cu@Zn-BDC MOF) for tetracycline (TC) removal from aqueous solutions and hospital wastewater. The modified biochar exhibited strong magnetic properties (19.803 emu/g) and a specific surface area of 30.

In recent years, the accumulation of waste plastics and emergence plastic-derived pollutants such as microplastics have driven significantly the development and updating of waste plastic utilization technology. This study prepared the porous carbon (PC-1-KOH) material directly from polyethylene terephthalate (PET) in waste plastic bottles using KOH activation and molten salt strategy for efficient removal of antibiotic tetracycline (TC). The maximum removal efficiency of TC was 100.
