Microwave-assisted one-step extraction-derivatization for rapid analysis of fatty acids profile in herbal medicine by gas chromatography-mass spectrometry.

Rui-Lin Liu et al.

The Analyst, 137(21), 5135-5143 (2012-09-13)

A rapid and practical microwave-assisted one-step extraction-derivatization (MAED) method was developed for gas chromatography-mass spectrometry analysis of fatty acids profile in herbal medicine. Several critical experimental parameters for MAED, including reaction temperature, microwave power and the amount of derivatization reagent

A novel sample preparation method using rapid nonheated saponification method for the determination of cholesterol in emulsified foods.

In-Seek Jeong et al.

Journal of food science, 77(10), C1042-C1046 (2012-09-18)

In this study, nonheated saponification was employed as a novel, rapid, and easy sample preparation method for the determination of cholesterol in emulsified foods. Cholesterol content was analyzed using gas chromatography with a flame ionization detector (GC-FID). The cholesterol extraction

Decontamination and digestion of infectious animal waste using a tissue dissolver in an animal biosafety level 3 facility.

Lesley C Homer et al.

Lab animal, 41(11), 327-335 (2012-10-20)

Alkaline hydrolysis-based tissue dissolvers (TDs) are commercially available tools for the digestion and decontamination of infectious animal waste. The authors carried out a series of experiments to verify whether the TD in their facility completely digested animal carcasses and inactivated

Potential of potassium hydroxide pretreatment of switchgrass for fermentable sugar production.

Rajat Sharma et al.

Applied biochemistry and biotechnology, 169(3), 761-772 (2013-01-01)

Chemical pretreatment of lignocellulosic biomass has been extensively investigated for sugar generation and subsequent fuel production. Alkaline pretreatment has emerged as one of the popular chemical pretreatment methods, but most attempts thus far have utilized NaOH for the pretreatment process.

A comparison of the contrast stains, Chicago blue, chlorazole black, and Parker ink, for the rapid diagnosis of skin and nail infections.

Evanthia Tambosis et al.

International journal of dermatology, 51(8), 935-938 (2012-07-14)

The cheapest, most rapid method for the diagnosis of mycotic skin and nail infections is direct examination of samples using a KOH preparation. The standard KOH wet mount lacks a color contrast. Various contrast dyes are available. Parker ink is
