Electrostatic microfiltration (EM) enriches and recovers viable microorganisms at low-abundance in large-volume samples and enhances downstream detection.

Rapid and sensitive detection of pathogens in various samples is crucial for disease diagnosis, environmental surveillance, as well as food and water safety monitoring. However, the low abundance of pathogens (<10 CFU) in large volume (1 mL-1 L) samples containing vast backgrounds critically limits the sensitivity of even the most advanced techniques, such as digital PCR. Therefore, there is a critical need for sample preparation that can enrich low-abundance pathogens from complex and large-volume samples.

Qualitative and quantitative analysis of and and efficacy study of herbal extracts on allergic contact dermatitis using 3D human reconstructed epidermis.

Objective: To evaluate the quality of (AR) and (DC) and study the efficacy of herbal extracts of these two herbs on the treatment of allergic contact dermatitis (ACD).

Methods: Qualitative and quantitative analysis of effective components was performed using High Performance Thin Layer Chromatography (HPTLC), High Performance Liquid Chromatography (HPLC), and HPLC-Quadrupole Time of Flight-Mass Spectrometry (HPLC-QTOF-MS). allergic ACD 3D model was established by incubating 3D reconstructed human epidermis (RHE) with skin sensitizer, potassium dichromate.

The Possibilities of Reducing Food Choice to Improve the Performance of College Foodservices.

Background: College administrative and management leaders, foodservice personnel, and student residents value social, nutritional, financial, and environmental sustainability in their dining expectations. Menu choice reduction looks promising as a strategy to achieve these goals. However, foodservice research about dominant attitudes across these stakeholders is limited.

A review of the determination of organic compounds in Bayer process liquors.

Bayer process liquors present a difficult and complex matrix to the analytical chemist, and the history of the application of modern analytical techniques to this problem is a case study in innovation. All Bayer process liquors contain organic compounds, in amounts varying from traces to several grams per litre. The total organic carbon content of Bayer liquors may be less than 5 g/L up to as much as 40 g/L.
