Four C.I. Solubilised Sulphur dyes were applied to cultivated silk fabric using sodium thioglycolate at pH 7, for 30 min at 60 °C in the absence of electrolyte. Medium/deep shades were obtained that displayed good/excellent fastness to washing at 40 °C and little or no sensitivity to oxygen bl...

This study was designed to improve the stability of liquid formulations of recombinant influenza hemagglutinin (rHA) and to understand the mechanism of early loss of potency for rHA. The potency of rHA derived from several influenza strains was determined using single radial immunodiffusion (SRI...

The nucleus of mammalian spermatozoa is mainly composed of chromatin associated with protamines: highly basic proteins (around 7 kDa). These highly basic proteins, due to their cysteine content, can participate in the generation of disulfide bond. These characteristics permit typical condensed n...

Characterization, thermal stability and thermal decomposition of light trivalent lanthanide nicotinates, Ln(C6H4NO2)3·nH2O (Ln = La to Gd, except Pm) were synthesized and investigated employing simultaneous thermogravimetry and differential scanning calorimetry (TG–DSC), Fourier transform infr...

Hydroxytyrosol (HT) is a natural polyphenol antioxidant that exists in olive oil. In the study of multifunctional hypolipidemic of nicotinic derivatives, we found that hydroxytyrosol nicotinate (HT-N) incorporation of niacin with HT displayed α-glucosidase inhibitory activities in vitro, such a...

A three novel vitamin based ionic liquids, cholinium nicotinate, cholinium biotinate and cholinium ascorbate were synthesized and characterized. For the first time the acidity constant for biotin was determined. Physicochemical properties such as density, electrical conductivity and viscosity we...

ObjectiveWe previously reported on vitamin E malabsorption after gastrectomy. In this study, we focused on neurological dysfunction due to serum vitamin E decrease during the postgastrectomy period in lager number of patients.

A sensitive and rapid reversed-phase ultra performance liquid chromatographic (UPLC) method for the simultaneous determination of tocopherols (α‐, β‐, γ‐, δ‐), tocotrienols (α‐, β‐, γ‐, δ‐), α‐tocopherol acetate and α‐tocopherol nicotinate is described. The separation was ach...

An HPLC method is described using normal phase conditions with an unbonded silica column to determine concentrations of supplementary vitamin A and vitamin E esters and β-carotene in infant formulae. The method utilises selective dual-channel fluoresence for vitamins A and E and visible absorba...

Nicotinamide adenine dinucleotide (NAD) biosynthesis, including synthesis from aspartate via the de novo pathway and from nicotinate (NA) via the Preiss–Handler pathway, is conserved in land plants. Diverse species of NA conjugates, which are mainly involved in NA detoxification, were also foun...

The detailed volumetric and viscometric investigation of three vitamin-based ionic liquids (ILs): cholinium biotinate ([Ch][Biot]), cholinium ascorbate ([Ch][Asc]) and cholinium nicotinate ([Ch][Nicot]), have been performed in this article in order to get insight about the taste of ILs. The appa...

Taking into account the great interest of consumers for high purity natural vitamin E preparations, it is highly desirable to develop an efficient process for recovering Vitamin E from vegetable oil deodorizer distillates (VODDs) with reduction in costs and better use of energy. The process desc...

Present work reports on studies of sodium nicotinate solutions in water and aqueous ethanol by means of 1H, 13C, 15N NMR spectroscopy. The H(2) nucleus was observed to be the least shielded among pyridine ring protons whilst C(6) signal placed in the lowest field in relation to the other pyridin...

SummaryObjectiveRecently, the transcription factor AP-2ɛ was shown to be a regulator of hypertrophy in cartilage and to be differentially expressed in osteoarthritis (OA). However, the only known target gene of AP-2ɛ up to date is integrin alpha10. To better characterize the function of AP-2ɛ in...

In non-desert areas primary biological aerosol particles, including pollen, are an important source of phosphorus (P). During the flowering season large quantities of pollen from wind pollinated trees, are observed in boreal and temperate lakes and forest, which contain high P concentrations. Ho...

A lanthanum based phosphate coating on magnesium AZ31 alloy was prepared through chemical conversion coating technique and characterized their corrosion performance. The coating was obtained in a two stage procedure using two different solvents, water or ethanol for preparing the coating nitrate...

Calcium phosphates (CaP) based materials are widely recognized as the most suitable matrix for bone tissue engineering. The cationic and anionic substitutions of CaP structure by the elements and groups of biological importance seem to be the effective ways to improve the properties of CaP-based...

Developing non-noble metal catalysts with high performance to reduce the cost of hydrazine fuel cells is urgent. Herein, in this study, a series of carbon-supported phosphatized CuNi catalysts (P-CuxNiy/C) are designed for hydrazine oxidation reaction (HzOR) via high temperature phosphating proc...

Phosphorous is one of three major nutritional elements for plants and usually exists as phosphate ions in nature. For hydroponic culturing and wastewater treatment, the development of a high-performance phosphate sensor would be very helpful. A novel phosphate ion-selective electrode was constru...

The production, isolation, purification and characterization of soluble Extracellular Polymeric Substances (EPS) secreted by Pseudomonas veronii 2E were studied. Optimal production was obtained in medium M9-14 g l−1 glycerol, 25 °C. Spectrophotometric and potentiometric titration studies showed...
