The cultivated almond displays a gametophytic self-incompatibility system, which avoids self-fertilization, and it is controlled by multi-allelic locus (S-locus) containing two genes specifically expressed in pistil (S-RNase) pollen (SFB). Studies on almonds with the same S-haplotype but different phenotype pointed to existence of unknown components this system explain its functioning. increase...

Journal: :Food Control 2023

Surge in consumption of healthy and safe foods has challenged researchers to develop sensitive, precise, robust detection quantification food contaminants like acrylamide even if they are present trace. Keeping this view, a sensitive analytical method was developed validated for potato-based product (potato cutlet), using LC-MSMS with positive electrospray ionization (+ESI). The consists adding...

A new analytical method has been developed and is proposed for the rapid determination of eighteen common amino acids, including tryptophan, in plasma and dried blood spots, by liquid chromatography coupled with ionspray tandem mass spectrometry. Potentially the method can include other amino acids and can be used for the diagnosis of metabolic disease. The use of the ionspray tandem mass spect...

The pollution of water bodies by pharmaceuticals and personal care products (PPCPs) has attracted widespread concern due to their use pseudo-persistence, but effects on sediments are less known. In this study, solid-phase extraction-high performance liquid chromatography–tandem mass spectrometry (SPE-LC/MSMS) was used investigate the occurrence ecological risks five typical in thirteen key rese...

The scallop, Patinopecten yessoensis, was screened for new saxitoxin analogues to study the metabolism of paralytic shellfish toxins (PSTs), and this resulted in discovery two analogues: M5-hemiaminal (HA) M6-HA. M5-HA isolated its structure determined by using NMR spectroscopy. It contains hydrogen at C-4 with opposite stereochemistry that saxitoxin, a hemiaminal formed between 9-NH2 hydrated ...
