Hematoheme displays a potent cytolytic activity toward erythrocytes either in the presence of hydrogen peroxide and a halide ion (system I) or in the presence of oxygen and a reducing agent (system II). In system I it resembles the cytotoxic activity of various peroxidases, whereas in system II ...
In recent years squarines received attention as fluorescent labels. Their very promising spectral properties such as long wavelength absorption and emission, high extinction coefficients and quantum yields could lead novel sensing technologies. In this work newly synthesized fluoroinophores name...
Three different zinc oxide nanoparticles (ZnONP) were prepared, each of them was prepared with a different source of zinc (zinc acetate, zinc chloride, zinc nitrate) and they were used to prepare PLA/PBAT-ZnONP composite films. The effects of the different type of ZnONP on the morphological, wat...
The food industry has been using antimicrobial active packaging as a tool for maintaining the quality of highly perishable products such as fish products. The use of synthetic materials, though, causes serious environmental impacts due to inappropriate disposal. Therefore, eco-friendly polymer m...
The objective of work was to produce and characterize biodegradable films from rice flour, poly(butylene adipate co-terephthalate) (PBAT), glycerol and potassium sorbate, for application as active packaging for fresh lasagna pasta. The films were evaluated with respect to their optical, water va...
In order to control foodborne pathogens on seafood products, an antimicrobial, thermoplastic starch/polybutylene adipate terephthalate (TPS/PBAT; 40/60) film was produced by coating gelatin (15% v/v) containing lauric arginate (LAE; 0.8 mg/cm2), alone or combination with nisin Z (69.4 AU/cm2) to...
This study was aimed at producing acetylated adipate of retrograded starch (ADA-R) with various degrees of substitution with functional groups and at determining the effect of esterification degree on resistance and pasting characteristics of the produced preparations.Paste was prepared from nat...
Di (2-ethylhexyl) adipate (DEHA) is a potential plasticizer alternative for di-2-ethylhexyl phthalate (DEHP). Toxicity of DEHA has been studied mostly via oral exposure but not assessed after repeated intravenous exposure. The present study shows the toxicity effects after intravenous administra...
Poly(glycerol adipate) (PGA) is a biodegradable, biocompatible, polymer with a great deal of potential in the field of drug delivery. Active drug molecules can be conjugated to the polymer backbone or encapsulated in self-assembled nanoparticles for targeted and systemic delivery. Here, a range ...
The reversible reaction of Rh4(CO)12 with carbon monoxide under pressure to yield thermally unstable Rh2(CO)8 has been studied by high-pressure infrared spectroscopy. The equilibrium constant and the thermodynamic parameters of this reaction have been determined in the temperature range +30 to −...
Previously reported (J. Organomet. Chem., 246 (1983) 309) experimental data for the equilibrium constants and thermodynamic parameters of the reversible reaction 2 Rh2(CO)8 ⇄ Rh4(CO)12 + 4 CO have been re-evaluated using more reliable values for the solubility of carbon monoxide in hexane at low...
The homogeneous rhodium catalyzed hydroformylation of ethylene was studied, starting with Rh4(CO)12 in n-hexane solvent, at 293 K under 1.0–4.0 MPa CO, 0.5–2.0 MPa H2 and 0.5–5.0 MPa C2H4. The analytic method was in situ high-pressure infrared spectroscopy. Two different metal carbonyl spectr...
It is well known that the liquid-phase homogeneous unmodified rhodium catalysed hydroformylation of alkenes is poisoned by the presence of trace quantities of conjugated dienes. Nevertheless, some hydroformylation of conjugated dienes is possible with unmodified rhodium, and this reaction is in ...
The solvent extraction of some base metals by mixtures containing a carboxylic acid and an alkylpyridine synergist was studied, with particular reference to the separation of nickel from calcium in sulphate media. The dependence of the synergistic shift in the pH50 value (ΔpH50) and the Ni–Ca ...
CYP199A2, a cytochrome P450 enzyme from Rhodopseudomonas palustris, oxidatively demethylates 4-methoxybenzoic acid to 4-hydroxybenzoic acid. 4-Ethylbenzoic acid is converted to a mixture of predominantly 4-(1-hydroxyethyl)-benzoic acid and 4-vinylbenzoic acid, the latter being a rare example of ...
In this study, the pulsed pressure-assisted brining technology was used for bacon brining, and its effect on the moisture and lipid oxidation changes during drying-ripening period as well as the flavor composition of final products was investigated by determining the moisture content, acid value...
In this chapter, the polymerization process of poly(lactic acid) (PLA) is discussed. Information is given about the production of PLA from the very start of the process, including fermentation to produce lactic acid followed by lactide and finally catalysis conversion of prepolymer.
Iron 2-ethylhexoate is a salt of ferric iron and 2-ethylhexanoic acid. It is incorporated into silicone elastomeric formulations to provide high temperature stability by counteracting oxidative embrittlement. Though metallic salts are commonly used, the reaction of the salt with the siloxane is ...
Iron complexes of the PDP family [((S,S)-PDP)FeII(OTf)2] (1) and [((S,S)-PDP*)FеIII(μ-OH)2FеIII((S,S)-PDР*)](ОTf)4 (3), (S,S)-PDР = N,N′-bis(2-pyridylmethyl)-(S,S)-2,2′-biрyrrоlidine, (S,S)-PDР* = N,N′-bis(3,5-dimеthyl-4-mеthоxypyridyl-2-mеthyl)-(S,S)-2,2′-biрyrrоlidine, and o...
Several 4-chloro-N-(4-oxopyrimidin-2-yl)-2-mercaptobenzenesulfonamide derivatives 13–28 and 35–44 have been synthesized and tested as potential HIV-1 integrase (IN) inhibitors. Compounds 15–17, 19, 21–28, 36 and 41 inhibited IN with IC50 values in the range of 3.3–63.0 μM. The compounds 13...
