The present study describes construction and investigation of experimental formulations of ammonium nitrate embedded in a matrix of degradable natural polymer poly-3-hydroxybutyrate (P3HB) and P3HB blended with wood flour shaped as tablets, some of them coated with P3HB. Kinetics of ammonium release into soil as dependent on the composition of the polymer matrix was investigated in laboratory experiments. The rates of fertilizer release from formulations coated with a biopolymer layer were considerably (two months or longer) slower than the rates of fertilizer release from uncoated formulations, while release from polymer and composite (polymer/wood flour) formulations occurred with comparable rates...

NADPH oxidase 4 (NOX4) with the sole function to produce reactive oxygen species (ROS) can be a molecular target to disrupt cancer metastasis. Several studies have indicated that lycopene exhibited anti-metastatic actions in vitro and in vivo. However, the role of NOX4 in the anti-metastatic action of lycopene remains unknown. Herein, we first confirmed the anti-metastatic effect of lycopene (0.1-5 μM) on human liver adenocarcinoma SK-Hep-1 cells. We showed that lycopene significantly inhibited NOX4 protein expression with the highest inhibition of 64...

Factors including genetics, fertilization, and climatic conditions, can alter the biomass composition of soybean seeds, consequently impacting their market value and usage. This study specifically determined the content of protein and oil, as well as the composition of proteinogenic amino acids and fatty acids in seeds from ten diverse soybean cultivars grown in four different sites. The results highlighted that different environments produce a different composition for the ten cultivars under investigation...

Phytogenic feed additives represent a potential alternative to antibiotics with attributed health and growth promoting effects. Chickens supplemented with an essential oil blend, a Quillaja saponin blend or a combination of both phytogenic preparations showed a comprehensively and significantly improved apparent ileal digestibility of crude protein and amino acids compared to control birds. Accordingly, holistic transcriptomic analyses of jejunum and liver samples indicated alterations of macromolecule transporters and processing pathways likely culminating in an increased uptake and metabolizing of carbohydrates and fatty acids...

Curcumin is a dominating active component of curcuma longa and has been studied widely because of its prominent biological activities. Extremely low aqueous solubility, stability and bioavailability of curcumin limits its application in the field of medicine. In this study, we developed pectin-curcumin (PEC-CCM) conjugates which could self-assemble water-soluble nano-micelles in aqueous solution. The structure of PEC-CCM conjugates was characterized by ultraviolet and visible spectra (UV-Vis), fluorescence spectra, Fourier transform infrared (FTIR) spectroscopy and 1H nuclear magnetic resonance (NMR) spectroscopy...

Chitinase ChiEn1 did not hydrolyze insoluble chitin but showed hydrolysis and transglycosylation activities towards chitin-oligosaccharides. Interestingly, the addition of ChiEn1 increased the amount of reducing sugars released from chitin powder by endochitinase ChiIII by 105.0%, and among the released reducing sugars the amount of (GlcNAc)2 was increased by 149.5% whereas the amount of GlcNAc was decreased by 10.3%. The percentage of GlcNAc in the products of chitin powder with the combined ChiIII and ChiEn1 was close to that in the products of chitin-oligosaccharides with ChiEn1, rather than that with ChiIII...

In red wine, the contents of higher alcohols and ethyl carbamate (EC) are two significant health concerns. To reduce the production of higher alcohols by wine yeast YZ22 with low production of EC, one BAT2 was replaced by a BAT1 expression cassette first and then another BAT2 was deleted to obtain the mutant SYBB3. Real-Time quantitative PCR showed that the relative expression level of BAT1 in SYBB3 improved 28 times compared with that in YZ22. The yields of isobutanol and 3-methyl-1-butanol produced by mutant SYBB3 reduced by 39...

Microalgal long-chain polyunsaturated fatty acids (LC-PUFAs) have emerged as promising alternatives to depleting fish oils. However, the overproduction of LC-PUFAs in microalgae has remained challenging. Here, we report a sequential metabolic engineering strategy that systematically overcomes the metabolic bottlenecks and overproduces LC-PUFAs. Malonyl CoA-acyl carrier protein transacylase, catalyzing the first committed step in type II fatty acid synthesis, and desaturase 5b, involved in fatty acid desaturation, were coordinately expressed in Phaeodactylum tricornutum...

The effect of standard bakery concentrations of microbial transglutaminase (MTG) in wheat bread preparation on the immunoreactivity of celiac disease (CD) patients' sera was investigated. Immunoblotting using monoclonal antibodies specific to unmodified and/or deamidated gliadin showed no differences between control bread and MTG-bread. Deamidation of gliadin could not be detected at standard MTG concentrations. CD patients' sera were characterized using anti-gliadin and anti-DGP ELISA and grouped into DGP high and low titer pools...

Thiouracil (TU), synthesized for its thyroid-regulating capacities and alternatively misused in livestock for its weight-gaining effects, is acknowledged to have an endogenous origin. Discrimination between low-level abuse and endogenous occurrence is challenging and unexplored in an experimental setting. Therefore, cows (n = 16) and calves (n = 18) were subjected to a rapeseed-supplemented diet or treated with synthetic TU. Significant higher urinary TU levels were recorded after TU administration (<CCα, 15 642 μg L(-1)) compared to rapeseed supplementation (<CCα, 65...

Heavy metal excess in soil represents a critical problem for crop productivity. Among these pollutants, cadmium (Cd) is one of the most dangerous in terms of food-chain contamination. Two durum wheat near-isogenic lines (NILs) and 12 commercial varieties (cultivars Arcangelo, Aureo, Aziziah, Cappelli, Cirillo, Creso, Iride, Maestrale, Parsifal, Russello, Strongfield, and Svevo) of durum wheat were exposed to a nontoxic level of Cd to evaluate its concentration in grains, roots, and shoots, as well as effects on biomass production...

A series of new kresoxim-methyl derivatives, (pyridinylphenoxymethylene)phenyl methoxyiminoacetates, were synthesized and their structures were confirmed by NMR and high-resolution mass spectrometry (HRMS). Although derived from a fungicide, the bioassays indicated that several new compounds had good herbicidal activities. At 37.5 g a.i./ha, compound 5c showed 100% inhibition against Abutilon theophrasti, Amaranthus retroflexus, and Eclipta prostrata, which was better than mesotrione. Compound 5e had a broad herbicidal spectrum against broadleaf weeds...

The adipocyte differentiation process, controlled by a tightly regulated transcriptional cascade, contributes partly to determine intramuscular adipose tissue (IMAT) mass, which is associated with meat quality in food animals, as well as obesity and related metabolic complications in human. Thus, this study aimed to characterize genes critical for intramuscular preadipocyte differentiation. Primary intramuscular preadipocytes were isolated from pigs, and mRNA profiles were performed at several key points (0 h, 4 h, 8 h, 1 day, 2 days, and 6 days) during adipogenesis using microarrays...

Utilization of renewable biomass to partly replace the fossil resources in industrial applications has attracted attention due to the limited fossil feedstock with the increased environmental concerns. This work introduced a modified Wacker-type oxidation for transformation of unsaturated fatty acids/esters to the corresponding keto fatty acids/esters, in which Cu2+ cation was replaced with common non-redox metal ions, that is, a novel Pd(II)/Lewis acid (LA) catalyst. It was found that adding non-redox metal ions can effectively promote Pd(II)-catalyzed oxidation of unsaturated fatty acids/esters to the corresponding keto fatty acids/esters, even much better than Cu2+, and the promotional effect is highly dependent on the Lewis acidity of added non-redox metal ions...

An epidemic fungal disease caused by Fusarium proliferatum, responsible for fumonisin production (FB1, FB2, and FB3), has been reported in the main garlic-producing countries in recent years. Fumonisins are a group of structurally related toxic metabolites produced by this pathogen. The aim of this work was to establish an ELISA procedure, mostly applied to cereals, that is suitable for fumonisin detection in garlic, and compare these results with those obtained by HPLC and screening of fresh and dehydrated garlic for toxicological risk...

Plant hormones are important mobile endogenous signaling molecules that regulate responses to abiotic stress as well as plant growth and development. Visual information on more than one plant hormone from the same sample would be especially powerful, because it could enable rapid, intuitive interpretation. However, multi-imaging techniques for plant hormones have been unavailable. Here, we report the first multi-imaging of two plant hormones, one of cytokinin (i.e. trans-zeatin) and abscisic acid (ABA) by MALDI-TOF-MS imaging...

Cancer is the major cause of morbidity and mortality worldwide. Hydroxycinnamic acids (HCAs) are naturally-occurring compounds and their alkyl esters may possess enhanced biological activities. We evaluated C4, C14, C16 and C18 alkyl esters of p-coumaric, ferulic, sinapic and caffeic acids (19 compounds) for their cytotoxic activity against four human cancer cells and also examined their effect on cell cycle alteration and apoptosis induction. The tetradecyl (1c) and hexadecyl (1d) esters of p-coumaric acid and tetradecyl ester of caffeic acid (4c), but not the parental HCAs, were selectively effective against MOLT-4 (human lymphoblastic leukemia) cells with IC50 values of 0...

A study into doses of seed treatments and foliar plant protection products containing an identical active substance registered to control the same pest in the same crops was carried out in the European Union. The results show that, for fungicides, the use of seed treatment is often connected with a significantly lower release of active substance per hectare when compared to foliar treatments. In 11 of 13 cases, the difference was 8-fold or higher. For insecticides, in most of the cases, the consumption of an active substance was several times higher for seed treatment, in one case for foliar application...

This study investigates chemical information of volatile fractions of high-quality cocoa (Theobroma cacao L. Malvaceae) from different origins (Mexico, Ecuador, Venezuela, Columbia, Java, Trinidad, and Sao Tomè) produced for fine chocolate. This study explores the evolution of the entire pattern of volatiles in relation to cocoa processing (raw, roasted, steamed, and ground beans). Advanced chemical fingerprinting (e.g., combined untargeted and targeted fingerprinting) with comprehensive two-dimensional gas chromatography coupled with mass spectrometry allows advanced pattern recognition for classification, discrimination, and sensory-quality characterization...

The iron(IV) binding protein ferrylmyoglobin, MbFe(IV)═O, was found to be reduced by tyrosine based food components in aqueous solution through a sequential proton loss electron transfer reaction mechanism without binding to the protein as confirmed by isothermal titration calorimetry. Dopamine and epinephrine are the most efficient food components reducing ferrylmyoglobin to oxymyoglobin, MbFe(II)O2, and metmyoglobin, MbFe(III), as revealed by multivariate curve resolution alternating least-squares with second order rate constants of 33...
