The peroxidase-like activity of cytochrome c is considerably increased by unfolding of the protein. The enhancement of the activity is due to the higher reaction rate of unfolded cytochrome c with hydrogen peroxide, which is the rate-determining step in the peroxidase cycle of cytochrome c (Gębi...
The drug tetracycline hydrochloride (TC), which has cytotoxic and cytostatic effects on tumor cells, has been encapsulated within the nanocavity of apoferritin in the form of its EuIII complex (Eu3TC). The Eu3TC complex was encapsulated within apoferritin through disassembly followed by reassemb...
The interaction of SDS/SDBS in aqueous gelatin solutions is studied above the gelation temperature by viscosity and circular dichroism (CD) measurements. The steep rise observed in the relative viscosity can be due the structural transitions leading to micellar growth of higher order. Circular d...
A complete assessment of effects of pollutants in the environment requires the use of a wide assemblage of test organisms. Crustaceans have been widely used in aquatic environments, but within this group, ostracods have been overlooked, even though they are one of the commonest groups of animals...
A toxicologic and dermatologic review of 3,7-dimethyl-1-octanol when used as a fragrance ingredient is presented.
Experimental phase equilibrium data for the systems CO 2 +n-dodecane, CO 2 +1-decanol and CO 2 +3,7-dimethyl-1-octanol were used to determine values for binary interaction parameters for use in the RK-ASPEN thermodynamic model in Aspen Plus ® . Bubble and dew poin...
New high pressure VLE data for the ternary mixture CO2+n-dodecane (nC12)+3,7-dimethyl-1-octanol (37DM1O) are presented. A static apparatus with online analysis was used to measure phase compositions at 35, 55 and 75°C, and pressures between 68 and 157bar. In the high-nC12 region the mixture dis...
In order to prevent the electrolyte decomposition of liquid state Al-plastic film lithium-ion batteries during overcharge, the redox reactions of 2-chloro-1,4-dimethoxybenzene and 4-fluoro-1,2-dimethoxy-benzene as possible electrolyte additives were characterized by using overcharge tests, galva...
Synthetic routes for the following dendrimers are described: Si[CH 2 CH 2 Si(Me) 2 CH 2 -3,5-(MeO) 2 -C 6 H 3 ] 4 (2) and Si[CH 2 CH 2 Si(Me) 2 -2,4-(MeO) 2 -C 6 H 3 ] 4 (4). T...
The title compounds, [Mn(C10H8O6)]n and [Zn(C10H8O6)]n, are isomorphous coordination polymers prepared from 2,5‐dimethoxyterephthalic acid (H2dmt) and the respective metal(II) salts. Both complexes form three‐dimensional metal–organic frameworks with each MII centre bridged by four 2,5‐dimet...
We have previously reported the isolation of a vitamin E analog ([alpha ]-tocopherol succinate) from a green barley leaf extract, which stimulates the release of prolactin and growth hormone from rat anterior pituitary cells in vitro. In the present study, we tested the commercially available f...
The distribution equilibrium of lead(II) species between aqueous succinate media and n-octylaniline was studied as a function of the concentrations of extractant in organic phase, weak organic acid concentration, different diluents and effect of shaking period on extraction. The quantitative ext...
Liquid–liquid equilibria (LLE) of the 1-propanol/2-propanol/2-butanol/2-methyl-2-propanol+disodium tartrate or disodium succinate+water systems have been measured at T=298.15K. The Merchuk et al. equation was used to correlate the obtained binodal data. The effect of some factors such as length...
The leaves of Pycnanthus angolensis (Welw.) Warb., Myristicaceae, are used as memory enhancer and anti-ageing in Nigerian ethnomedicine. This study aimed at evaluating the cholinesterase inhibitory property as well as isolates the bioactive compounds from the plant. The acetylcholinesterase and ...
Phytol (PHY) (3,7,11,15‐tetramethylhexadec‐2‐en‐1‐ol) exhibits various pharmacological properties including toxicity and cytotoxicity, and exerts antitumor activity. Owing to the urgent need of new pharmaceutical formulations for breast cancer therapy, this study aimed at the evaluation of ...
Rates of photodegradation of chlorophylls in their entirety and of chlorophyll phytyl chains, and time evolution of the Chlorophyll Phytyl side-Chain Photodegradation Index (CPPI) under visible light exposure were determined and compared in laboratory experiments. Killed phytoplanktonic cells of...
The paracloacal gland secretions of a male and a female brown caiman (Caiman crocodilus fuscus) from Costa Rica were analyzed by gas chromatography-mass spectrometry. 3,7,11-Trimethyldodeca-6,10-dien-1-ol (2,3-dihydrofarnesol) and 20 of its esters, with acid moieties ranging in carbon-chain len...
The lipase-catalyzed citronellol synthesis of citronellyl acetate via transesterification was investigated in a solvent-free system. After screening several lipases, the lipase from Pseudomonas fluorescens was identified as the optimal enzyme for the system. The optimal reaction temperature was ...
BackgroundCitronellyl acetate (CAT), a monoterpene product of the secondary metabolism of plants, has been shown in the literature to possess several different biological activities. However, no antinociceptive abilities have yet been discussed. Here, we used acute pain animal models to describe...
2,5-bis(2-benzoxazolyl)-1,4-dimethoxybenzene (BBDB) and its symmetrically deuterated isotopomer (BBDB-d 2 ) were studied in supersonic jets. The laser induced fluorescence excitation (LIF(E)) spectra of both compounds made possible the unequivocal identification of the spectral origins b...
