aflatoxin B1; antibodies; antigen detection; biosensors; detection limit; enzyme-linked immunosorbent assay; immunoaffinity chromatography; immunochemistry; zearalenone
Abstract:
... Immunoreagents with good results in the competitive enzyme-linked immunosorbent assay are often unable to provide the required detection limit in the traditional competitive immunochromatographic assay. The solution may be either the production of new reagents or improving the test strip. In the latter case, the assay is often performed stepwise using additional liquid reagents, but this is a sign ...

Chironomidae; DNA barcoding; adults; barcoding; biodiversity; cost effectiveness; genetic markers; high-throughput nucleotide sequencing; larvae; midges; phylogeny; rare species; taxonomy; toxicity
Abstract:
... Several of the biggest challenges in taxonomy and systematics are related to a toxic mixture of small size, abundance, and rarity. There are too many species in groups with too few taxonomists and many of these species are very rare and hard to find because they are hidden in mass samples. To make matters worse, these species often have life‐history stages that are morphologically so different tha ...

From soapstock, which is a waste product of sunflower oil production, the fatty component was isolated using isopropyl alcohol, toluene, fusel oil and a mixture of common salt and nonionic surfactants. With the help of the Langmuir film balance the molecular areas of isolated fats were found and the degree of hydrophobization in comparison with the original soapstock was evaluated. It was found th ...

Abstract:
... 'Abnormal vertical growth' (AVG) was recognised in Australia as a dysfunction of macadamia (Macadamia spp.) in the mid-1990s. Affected trees displayed unusually erect branching, and poor flowering and yield. Since 2002, the commercial significance of AVG, its cause, and strategies to alleviate its affects, has been studied. The cause is still unknown, and AVG remains a serious threat to orchard vi ...

During field screening trials of a number of known cerambycid pheromones in China, males of Megopis costipennis (White) (Coleoptera: Cerambycidae: Prioninae: Callipogonini) were found to be specifically attracted to racemic anti-2,3-octanediol, suggesting that one of the enantiomers of this compound might be a female-produced sex pheromone of this species. Analysis of volatiles produced by beetles ...

Abstract:
... Procedures for the analysis of turnover of chemicals (and of natural compounds) are well developed using radio or stable isotope labelled tracer compounds in various standardized OECD tests. Due to the analytical focus on the isotope label the chemical speciation of the so-called non-extractable residues (NER) in soils and sediments often remains unknown. These NER may stem from parent compounds, ...

However, bulk g-C₃N₄ prepared from direct polycondensation still suffers from a high charge recombination rate and low photocatalytic activity. Herein, a facile (NH₄)₂SO₄-modified polycondensation strategy was developed for the synthes ...

... A human study of the effects on hemodynamics of caffeine and epigallocatechin-3-O-gallate (EGCG) was performed. Caffeine tablets (200 mg) were orally administered to healthy males aged between 25 and 35 years 30 min after oral administration of EGCG tablets (100 and 200 mg). The increase in BP induced by caffeine was inhibited when co-administrated with EGCG. We found that caffeine slightly decrea ...

Abstract:
... The most potent microtubule assembly inhibitor of newer diphenylpyridazinone derivatives examined was NSC 613241. Because NSC 613241 and (−)-rhazinilam also induce the formation of similar 2-filament spirals, these aberrant reactions were compared. Spiral formation with both compounds was enhanced by GTP and inhibited by GDP and by 15 other inhibitors of microtubule assembly. Similarly, microtubul ...

Abstract:
... Chiral carbon nanoparticles (CCNPs) were developed by surface passivation using the chiral ligand (−)-sparteine or (+)-sparteine (denoted (−)-SP/CNP and (+)-SP/CNP, respectively). The chirality of the prepared CCNPs was demonstrated by circular dichroism and polarimetry and employed as an enantioselective separation platform for representative racemic mixtures. ...

Epicatechin derivatives (1, 3 and 5), polyphenols (6 and 7) from Orostachys japonicus, and catechin derivatives (2 and 4) from our in-house library were evaluated for their inhibitory activity on cholinesterase. Compound 5 exhibited IC50 values of 58.3±2.4 and 17.8±3.8μg/mL on AChE and B ...

The genus is superficially similar to representatives of the Neotropical subfamily Discocephalinae, but the labium, which arises anteriad of the imaginary line traversing head at anterior limit of the eyes, exludes such a possibility. The new genus exhi ...

Possible relations with other species and an identification key for the Mexican specie ...

The line was developed as a potentially new source of resistance to Fusarium head blight (FHB) in wheat. 00Ar134-1 is resistant to Fusarium head blight as well as leaf rust, stem rust, and common bunt. Although lower yielding and taller than commercial cultivars, this line is of similar maturity and kernel wei ...

Abstract:
... With the different kinds of fuel now available, modern spark ignition engines have to be adapted, owing not only to the difference between the characteristic heat of combustion of the different fuels, but also to the response of the flame to stretch. As the burning rate is a function of the laminar burning speed which is a function of the flame stretch, this parameter has to be taken into account ...
