The aim of this work was the preparation of solid lipid nanoparticles, based on trehalose monooleate, loaded with cyclosporin-A for potential treatment of psoriasis. Trehalose was esterified with oleic acid in order to obtain a more lipophilic compound suitable as a lipid matrix for the formulat...
Densities and kinematic viscosities of polymer absorbents such as poly(propylene glycol) diglycidyl ether(PPDE) with molecular weights of 380 and 640, and poly(ethylene glycol) monooleate(PEGM) with molecular weight of 460 were respectively measured at atmosphere and temperatures ranging from 27...
The effects of six triaryl phosphate compounds on the primary productivity of pure algal cultures and natural phytoplankton in lake water were tested. Substitution of the hydrogen atom by a methyl group in the benzene ring decreased its effect. Triphenyl phosphate was the most toxic compound, fo...
A differential-pulse polarographic procedure is described for the determination of impurities such as diisooctyl maleate and maleic acid in pharmaceutical products. The concentration range for diisooctyl maleate is 1 × 10 −6−30 × 10−6 μg ml−1 and the detection limit is 0.2 μg ml−1; for malei...
Oils and fatty acids are important renewable resources provided by nature. Therefore, biotransformation of renewable oils and fatty acids into industrially relevant C9 chemicals was investigated in this study. Olive oil, soybean oil, yeast derived oil, and microalgae fatty acid methyl esters wer...
Whole-cell biotransformation is one of the promising alternative approaches to microbial fermentation for producing high-value chemicals. Baeyer–Villiger monooxygenase (BVMO)-based Escherichia coli biocatalysts have been engineered to produce industrially relevant C9 chemicals, such as n-nonano...
The aim of the study was to investigate the occurrence and formation of peroxygenase catalysed non-volatile oxidised fatty acids (NVOFAs), especially epoxy and hydroxy fatty acids, which potentially provide off-flavours in oat. A method based on extraction of NVOFAs using accelerated solvent ext...
Hydroxy fatty acid dehydrogenase, which is involved in polyunsaturated fatty acid saturation metabolism in Lactobacillus plantarum AKU 1009a, was cloned, expressed, purified, and characterized. The enzyme preferentially catalyzed NADH-dependent hydrogenation of oxo fatty acids over NAD+-dependen...
Fatty acids have a low permeability through the cell membrane. Therefore, the intracellular biotransformation of fatty acids can be slow due to supply limitations. The effects of expression level of the fatty acid transporter FadL in Escherichia coli on the biotransformations were investigated. ...
An alkaline solution for the electrodeposition of Fe-Mo alloys was developed with trisodium nitrilotriacetate (NTA3 −) as the complexing agent for Fe(III). The Fe-Mo voltammetric profile in the presence of 0.11 M NTA and 0.055 M NTA showed, respectively, two cathodic waves and one cathodic wave....
This paper shows the study of silver–zinc electrodeposition from a thiourea solution with added (ethylenedinitrilo)tetraacetic acid (EDTA), disodium salt and N-(2-hydroxyethyl)ethylenediaminetriacetic acid (HEDTA), trisodium salt. Voltammetric results indicated that silver–zinc alloy can be ob...
Methyl 4-O-(4-α-d-glucopyranosyloxy-4-methoxybutyl)-α-d-glucopyranoside (9) was synthesised by transacetalation from methyl 2,3,6-tri-O-acetyl-4-O-(4,4-di-methoxybutyl)-α-d-glucopyranoside and trimethylsilyl 2,3,4,6-tetra-O-acetyl-α-d-glucopyranoside followed by removal of the blocking group...
3-Azi-1-methoxybutyl β-d-galactopyranoside, prepared from 2,3,4,6-tetra-O-acetyl-α-d-galactopyranosyl bromide in four steps, had an affinity constant for antigalactans IgA (Fab′) J539 and X24 of 1550 and 1730 m−1, respectively. 3-Azi-1-methoxybutyl β-d-(4-3H)galactopyranoside, when photolyse...
The present paper discusses the microstructural evolution of aluminum hydroxide (AH3) formed during the hydration of calcium sulfoaluminate in neutral and alkaline solutions (0-M NaOH, 0.01-M NaOH, 0.1-M NaOH, 1-M NaOH, 5-M NaOH and 8-M NaOH). Rietveld method and field emission scanning electron...
The reduction of samarium in air fired samples of barium tetraborate has been identified for the first time by divalent samarium emission spectroscopy. The samarium(II) fluorescence is significantly quenched at ambient temperatures, but is apparent upon cooling of the sample to 77 K. Formation o...
The preparation and capacitive behaviour of boron-doped birnessite-type manganese dioxide is described. The MnO2 has been deposited directly onto carbon fiber substrate via the in-situ redox reaction between KMnO4 and carbon fiber in the presence of sodium tetraborate. A combination of physical ...
Interaction of CD28 with CD80 or CD86 molecules provides a costimulatory signals required in T cell activation. In this study, we cloned and analyzed a CD28 gene (On-CD28) and a CD80/86 gene (On-CD80/86) from Nile tilapia (Oreochromis niloticus). Sequence analysis revealed the typical characteri...
In rice, OsBBX14, a B-box (BBX) transcription factor, reportedly delays heading. Here, we revealed that OsBBX14 positively regulates rice photomorphogenesis. The OsBBX14-overexpressing (OsBBX14-OX) seedlings were hypersensitive to light, especially blue light, and exhibited dwarfism, while the O...
TmxY1−xAl3(BO3)4 nanocrystalline powders, with x = 0.040, 0.080, 0.120, 0.160, 0.320 and 1.000 in mol, prepared by the polymeric precursor method and heat-treated at 1150 °C were characterized by X-ray diffraction (XRD), high-resolution transmission electron microscopy (HRTEM), and selected are...
Azo dyes are widely used in the textile industry despite being poorly biodegradable and highly toxic. Hence, azo dyes need to be removed from effluent prior to environmental discharge. Microbial communities are efficient for the degradation and mineralization of azo dyes. However, little is know...
