Study on a New Ultraviolet Sterilizer to the Surface Disinfection of the Ultrasound Probe.

We studied the disinfection effect of a new ultraviolet (UV) sterilizer and its utilization on ultrasound probe surfaces. Carrier quantitative germicidal tests, simulated on-the-spot trials, and organic substance influence tests were used to carry out experimental observation. Artificially infected probes were disinfected using the sterilizer or a germicidal lamp for comparison.

Hepatoid adenocarcinoma of the stomach: A case report and literature review.

Hepatoid adenocarcinoma (HAC) is a rare form of gastric cancer that has unique clinicopathological features and an extremely poor prognosis. The present case report describes a patient who was referred to the No. 461 Hospital of PLA (Changchun, China) due to nausea and occasional vomiting of acid/water.

Responses of Phanerochaete chrysosporium to toxic pollutants: physiological flux, oxidative stress, and detoxification.

The white-rot fungus Phanerochaete chrysosporium has been widely used for the treatment of waste streams containing heavy metals and toxic organic pollutants. The development of fungal-based treatment technologies requires detailed knowledge of the relationship between bulk water quality and the physiological responses of fungi. A noninvasive microtest technique was used to quantify real-time changes in proton, oxygen, and cadmium ion fluxes following the exposure of P.

[Extracellular polymeric substances (EPS) of white-rot fungus and their effects on Pb2+ adsorption by biomass].

The extracellular polymeric substances (EPS) of P. chrysosporium and their effects on Pb2+ biosorption were studied. The product, composition of EPS and the effects on Pb2+ biosorption capacity were investigated in lab via flask experiments.

Coarsening of extracellularly biosynthesized cadmium crystal particles induced by thioacetamide in solution.

A novel coarsening route for extracellularly biosynthesized cadmium nanocrystals was investigated for the first time. In this process, the white rot fungus Coriolus versicolor was employed to take up cadmium ions and synthesize extracellular cadmium crystal particles. The coarsening of the particles was induced by thioacetamide under certain conditions.

Surface-modified Phanerochaete chrysosporium as a biosorbent for Cr(VI)-contaminated wastewater.

To improve the removal efficiency of heavy metals from wastewater, the surface of a fungal biomass was modified to obtain a high-capacity biosorbent for Cr(VI) in wastewater. The effects of pH, initial concentration, and sorption time on Cr(VI) removal by polyethylenimine (PEI)-modified Phanerochaete chrysosporium were investigated. The biomass adsorption capacity was significantly dependent on the pH of the solution, and the optimum pH was approximately 3.

Application of a by-product of Lentinus edodes to the bioremediation of chromate contaminated water.

The agricultural by-product of Lentinus edodes was used as a novel biosorbent for bioremediation of chromate contaminated waste water in the simulated experimental conditions. The contact time, particle size, biosorbent dosage and optimum pH range were investigated to optimize the sorption condition. The biosorption by the biomass was strongly affected by pH.

A novel biosorbent: characterization of the spent mushroom compost and its application for removal of heavy metals.

The spent mushroom compost of Lentinus edodes was used as a biosorbent for adsorbing cadmium, lead and chromium from solutions under batch conditions for the first time. Titration of the biomass revealed that it contained at least three types of functional groups. The Fourier transform infrared spectrometry showed that the carboxyl, phosphoryl, phenolic groups were the main groups.
