Deltamethrin, as a widely used pyrethroid insecticide, has caused significant environmental pollution due to its persistence and non-degradability in soil. Therefore, the immobilized microbial technology has shown good application potential due to its low cost and quick effect. Among them, Aspergillus niger as the representative of 17 kinds of bacterial mixed agents has strong tolerance and decomposition effect, can secrete a variety of degradation enzymes, can play a good degradation effect on ...

This study was conducted to investigate the acute toxic effects of ciprofloxacin, norfloxacin and florfenicol, which are widely used antibacterial drugs, on loach. Through a well-planned experimental design, we systematically monitored the physiological and behavioral characteristics of loach under different drug concentrations and exposure time, and evaluated the toxic effects of these drugs. Under specific test conditions, i.e. water temperature is maintained at (10.0 ± 2.0)℃, and the pH value...

Infrared (IR) dyes, especially those within the near-infrared (NIR) spectrum, hold significant promise for in vivo visualization, due to their ability to access biological tissues and significantly reduce background interference from autofluorescence. Nanoparticles integrated with IR dyes have undergone extensive investigation regarding their pharmacokinetic behavior, including biodistribution patterns and clearance mechanisms. These nanoparticles exhibit a remarkable ability to prefere...

In this study, gel-immobilized fillers were used to conduct partial nitrification experiments, including a small-scale experiment in the laboratory and a pilot experiment in a leather factory. The performance of the filler for partial nitrification was investigated by the small-scale experiment under the reactor start-up condition with low initial ammonia oxidizing bacteria (AOB) relative abundance. Then pilot experiment was carried out for the application of the filler in leather wastewater tre...

Citrobacter are Gram-negative bacteria that give public health challenges due to their zoonotic infections. Diarrheal diseases and antimicrobial resistance are global concerns that increase the burden of implementing infectious disease monitoring, especially in poor economic countries. This study was conducted to determine the prevalence and antimicrobial susceptibility and assess the risk factors of diarrheal diseases caused by bacteria from drinking water wells in the Urban West Regio...

Malaria is a parasitic disease caused by the protozoan parasites Plasmodium species, and usually transmitted through the bite of a female Anopheles species mosquito. Plasmodium falciparum is regarded as the most lethal of the Plasmodium species and most efforts are geared towards its control. Hitherto, with no available vaccines, an antimalarial drug such as Chloroquine was the main stay in the clinical management of uncomplicated P. falciparum malari...

We performed aurora kinase gene expression analysis, in combination with FISH and micronucleus test, in buccal mucosa cells isolated from agricultural workers to better understand the dynamics of genomic instability in these groups of professionals. Two out of a total of 97 agricultural workers who consented to participate in the study (39 men and 58 women) reported a history of cancer based on a previously applied questionnaire. The participants were 28.4 years on average and were categorized i...

Blotting is a classical technique for detecting macro-biomolecules of interest from a mixture of molecules. The technique is generally composed of four steps: 1) gel electrophoresis-based separation of molecules, 2) blotting (transfer and immobilization) of separated molecules from the gel onto the membrane, 3) specific hybridization of probes to target molecules on the membrane, and 4) visualization of the probe/target molecule complex. The present article briefly introduces blotting techniques...
