In this study, a sensitive high performance liquid chromatography coupled to a fluorescence detector (HPLC-FLD) method after post-column derivatisation was applied for the presence of aflatoxins (AFs) in 151 pistachios and 151 groundnuts from Turkey. Samples were collected between January 2010 and December 2012 in two provinces of Turkey and checked for AFs levels. Quantification limits were 0....

Article history: Received 01 July 2015 Accepted 29 July 2015 In the present study, simple and reliable method of histamine analysis was developed, optimized and validated to meet the requirements of fish safety. Histamine in fish samples was extracted with a methanol–phosphate buffer including 2 % TCA solution (50:50, v/v) followed by defatting with hexane after centrifugation at 13,000 rpm. Hi...

An HPLC-FLD method was developed using a surface response methodology for the quantification of silodosin in pharmaceuticals. The validated accuracy, precision, working range, reproducibility, limit detection, quantification, and robustness. Analytical Quality by Design (AQbD) strategy applied to develop an pharmaceuticals central composite design methodology. Excitation emission wavelengths wi...

In this work, deep eutectic solvent (DES) combined with ultrasonic-assisted extraction was proposed to extract free seleno-amino acids from Cardamine hupingshanensis. The contents of in the were determined by high-performance liquid chromatography a fluorescence detector (HPLC-FLD). Response surface design used optimize conditions such as ultrasonic time, temperature, and liquid-solid ratio. re...

Non-host resistance is the most ample and durable form of plant resistance against pathogen infection. It includes induction of defense-associated genes, massive metabolic reprogramming, and in many instances, a form of localized cell death (LCD) at the site of infection, purportedly designed to limit the spread of biotrophic and hemibiotrophic microorganisms. Reactive oxygen species (ROS) have...

The rapid increase in fatty liver disease (FLD) incidence is attributed largely to genetic and lifestyle factors; however, environmental toxicants are a frequently overlooked factor that can modify the effects of more common causes of FLD. Chronic exposure to inorganic arsenic (iAs) is associated with liver disease in humans and animal models, but neither the mechanism of action nor the combina...

Loss-of-function siz1 mutations caused early flowering under short days. siz1 plants have elevated salicylic acid (SA) levels, which are restored to wild-type levels by expressing nahG, bacterial salicylate hydroxylase. The early flowering of siz1 was suppressed by expressing nahG, indicating that SIZ1 represses the transition to flowering mainly through suppressing SA-dependent floral promotio...

Abstract Background To investigate the pharmacokinetics of 6- O -demethylmenisporphine, an oxoisoaporphine alkaloid with significant anti-tumor activities and isolated from Menispermi Rhizoma, a novel sensitive HPLC assay was established for -demethylmenisporphine quantification in rat plasma. Methods Peak responses were detected by highly selective fluorescence detector 426-nm excitation 514-n...

A novel method of Fisher’s linear discriminant (FLD) in the residual space is put forward for the representation of face images for face recognition, which is robust to the slight local feature changes. The residual images are computed by subtracting the reconstructed images from the original face images, and the reconstructed images are obtained by performing non-negative matrix factorization ...

To quantitatively evaluate the regional functional reserve in the cirrhotic liver and to seek related index that reflects diminished segmental liver function. A 3D system for quantitative evaluation of the liver was used to fuse technetium-99m galactosyl human serum albumin single-photon emission computed tomography and computed tomography images from 20 patients with cirrhotic liver and hepato...
