Biotechnological value of Moringa oleifera seed cake as source of insecticidal lectin against Aedes aegypti

Moringa oleifera seed cake, which is the coproduct of oil extraction, may be a source of lectin. This study reports the purification of a lectin from M. oleifera cake (WSMoLC) and the determination of its effect on larvae, eggs and oviposition of Aedes aegypti. WSMoLC was isolated (purification fold: 3573) by treatment of water extract with ammonium sulphate (60%) and chromatography of lectin-rich fraction on chitin column. In gel trypsin, digestion followed by mass spectrometry revealed the similarity of WSMoLC peptides with other M. oleifera seed proteins. WSMoLC exerted deleterious effects on larvae (LC50: 0.89?mg/mL) and eggs (EC50: 0.14?mg/mL) and served as an oviposition-stimulant at the concentration of 0.1?mg/mL. Larvicidal activity may be linked to lectin resistance to digestion and stimulatory effect on the activities of protease and alpha-amylase at larvae gut. Furthermore, the larvae did not start to express different enzymes in response to lectin effect. This study adds value to M. oleifera seed cake as a source of insecticidal lectin with high potential to be used in control of A. aegypti because, at the same time that it stimulates the oviposition by females, it could kill the eggs or larvae that may arise from them.

Assessment of Tokaj varietal wines with comprehensive two-dimensional gas chromatography coupled to high resolution mass spectrometry

Botrytised wines produced in Tokaj region belong to a special category of sweet wines described with a pleasant honey-like taste and a distinctive fruit flavour. Specific technological process of wine-making developed on macerating of noble-rotten berries in fermented juice or wine, results in alcoholic beverage indicated with the ‘Protected Designation of Origin’ label. A limited number of publications is devoted to analysis of Tokaj wines or by-products (e.g. individual varietal wines, essencia and must) which directly related to final characteristics of botrytized wine. A combination of two-dimensional gas chromatography connected to high-resolution mass spectrometry (GC ¡Á GC-HRTOFMS) offers enhanced separation and reliable identification of organic compounds presented in complex samples. In our study, this technique was applied to analyse varietal wines of the Tokaj wine region produced from three main grape cultivars (Furmint, Lipovina and Muscat Blanc a Petits Grains). The primary task was reliable separation and identification of low volatility compounds (acetamides, 2H-pyrrole- and 2H-pyran-based heterocyclic compounds and sulphur containing compounds) because of the lack of available information in this area. Thus, it revealed the presence of 1(3H)-isobenzofuranone, ethyl 1H-indole-3-acetate and 2-(methylmercapto)benzothiazole which were not previously detected in wine. Furthermore, trace aroma compounds (terpenoids and lactones) was quantified with modified stir bar sorptive extraction method which provided LOD and LOQ values of 2.3?4.7 ng/L and 7.7?15.8 ng/L, respectively. Linear calibration dependencies with correlation coefficients varying between 0.960 ? 0.996 were obtained.

Elastic-Plastic Transformation of Polyelectrolyte Complex Hydrogels from Chitosan and Sodium Hyaluronate

Hydrogels formed by polyelectrolyte complexation (PEC) of oppositely charged biopolymers, free of any chemical additives, are promising biomaterials. In this work, the mechanical behavior of hydrogels consisting of positively charged chitosan and negatively charged sodium hyaluronate (HA) at balanced charge composition is investigated. These hydrogels exhibit strong tensile strain and strain rate dependence. They are elastic-like, independent of the strain rate at small strain, but exhibit plastic-like behavior above the yield point by showing a monotonous decrease of the stress. The cyclic tensile test demonstrates that these hydrogels exhibit small and quickly recoverable hysteresis in the elastic-like region but large and partially recoverable hysteresis above the yield point. The stress relaxation experiment shows a plateau in the reduced stress followed by an abrupt fracture, and the time to failure decreases exponentially with increasing applied step strain. Such elastic-to-plastic-like transformation of the biopolymer PEC gels is quite different from the behaviors of PEC hydrogels formed by oppositely charged vinyl-type synthetic polyelectrolytes due to the difference in flexibility, charge density, and ionic bond strength of these polymers.

Mononuclear copper(II) complexes with quinolones and nitrogen-donor heterocyclic ligands: Synthesis, characterization, biological activity and interaction with DNA

The neutral mononuclear copper(II) complexes with the quinolone antibacterial drugs, pipemidic acid and N-propyl-norfloxacin, in the presence or absence of nitrogen-donor heterocyclic ligands, 2,2?-bipyridine, 1,10-phenanthroline or 2,2?-dipyridylamine, have been prepared and characterized spectroscopically. The interaction of copper(II) with the deprotonated quinolone ligand leads to the formation of the neutral mononuclear complexes of the type [Cu(quinolone)2(H2O)] (1)-(2) while the presence of the N-donor ligand leads to the formation of the neutral mononuclear complexes of the type [Cu(quinolone)(N-donor)Cl] (3)-(8). In all the complexes, copper(II) is pentacoordinate having a distorted square pyramidal geometry. The electron paramagnetic resonance spectra of 1 and 2 are typical of mononuclear Cu(II) complexes, while for the mixed-ligands complexes 3-8 a mixture of dimeric and monomeric species is indicated. The interaction of the complexes with calf-thymus DNA has been investigated with diverse spectroscopic techniques and has shown that the complexes can be bound to calf-thymus DNA by the intercalative mode. The antimicrobial activity of the complexes has been tested on three different microorganisms. All the complexes show an increased biological activity in comparison to the corresponding free quinolone ligand.

Study of the influence of the molecular organization on single-layer OLEDs’ performances

We have synthesized three new silole derivatives with incrementally flexible structure to tune their packing ability and therefore study the influence of the molecular organization in single-layer OLEDs. This architecture was chosen since the absence of organic layers interfaces allows a better evaluation of the role of the molecular arrangement in the active layer. The examination of the EL properties gives evidences of the prominent role of the molecular organization on the OLED efficiency. A crystalline-like organization of the molecules allows high current density but low luminance efficiency since an excessive electron current flow is involved compared to the hole one, and the recombination rate is poor. On the contrary, disordered assemblies of molecules allows better performances by avoiding unfavourable pi-stacking, while keeping good intermolecular orbital overlaps to support charge carrier transport.
