Abstract:
ABSTRACT Acylhomoserine lactones, which serve as quorum-sensing signals in gram-negative bacteria, are produced by members of the LuxI family of synthases. LuxI is a Vibrio fischeri enzyme that catalyzes the synthesis of N-(3-oxohexanoyl)-l-homoserine lactone from an acyl-acyl carrier protein andS-adenosylmethionine. Another V. fischeri gene,ainS, directs the synthesis ofN-octanoylhomoserine lactone. The AinS protein shows no significant sequence similarity with LuxI family members, but it does show sequence similarity with the Vibrio harveyi LuxM protein. The luxM gene is required for the synthesis ofN-(3-hydroxybutyryl)-l-homoserine lactone. To gain insights about whether AinS and LuxM represent a second family of acylhomoserine lactone synthases, we have purified AinS as a maltose-binding protein (MBP) fusion protein. The purified MBP-AinS fusion protein catalyzed the synthesis ofN-octanoylhomoserine lactone fromS-adenosylmethionine and either octanoyl-acyl carrier protein or, to a lesser extent, octanoyl coenzyme A. With the exception that octanoyl coenzyme A served as an acyl substrate for the MBP-AinS fusion protein, the substrates for and reaction kinetics of the MBP-AinS fusion protein were similar to those of the several LuxI family members previously studied. We conclude that AinS is an acylhomoserine lactone synthase and that it represents a second family of such enzymes.

Abstract:
A Fischer indole synthesis with a cis-configurated octahydroisobenzofuran-6-one yielded exclusively a furo[3,4-c]carbazole derivative as the product of a regioselective angular annulation reaction. A Friedländer quinoline synthesis from the same substrate gave a mixture of angular and linear annulation products, i. e. furo[3,4-a]acridine and furo[3,4-b]acridine derivatives. When submitting a mixture of cis- and trans-octahydroisoindole derivatives to Fischer and Friedländer syntheses, the trans-starting material gave regioselectively linear annulation products, i. e. pyrrolo[3,4-b]carbazole and pyrrolo[3,4-b]acridine derivatives. In contrast, the respective cis-configurated isoindole gavemixtures of angular and linear annulation products. The constitutions and relative configurations of nine new indole and quinoline derivatives were established by 2D NMR experiments and X-ray singlecrystal investigations.

Abstract:
The effects of support modification on cobalt based catalysts in Fischer-Tropsch synthesis were investigated. Part of silica support was modified with ammonia solution and the other part not. The Co/SiO2 catalyst with the support surface modified by ammonia solution showed larger particle size, strong Co-Si interaction, higher activity and selectivity in Fischer-Tropsch synthesis. It could be concluded that the support acidity can be controlled thus affected the reaction property of the catalysts in Fischer-Tropsch synthesis.

Abstract:
Interest in Fischer-Tropsch technology is increasing rapidly. Alkyl/alkenyl products from Fischer-Tropsch synthesis are alternative, renewable, environmentally and economically attractive fuels and there are considered one of the most favorable fuels for conventional fossil-based fuels. The chemistry of this gas-to-liquid industry converts synthesis gas containing carbon monoxide and hydrogen to oxygenated hydrocarbons such as alcohols. The fire hazards associated with the use of these liquid hydrocarbons mixtures are obvious. This article aims to explore the fundamental fire and explosion characteristics for main products composition from Fischer-Tropsch synthesis.

Abstract:
The influence of training on fatty acid and glyceride synthesis by liver and adipose tissue homogenates of young and old Fischer-344 rats was examined. Four groups of rats (10 animals/group) were studied: young untrained, young trained, old untrained, and old trained. Training of each group was for 10 wk at 75% maximal O2 uptake. Young rats were killed at 6 mo of age and old rats were killed at 27 mo of age. Fatty acid synthesis was assessed by measuring the activities of acetyl-CoA carboxylase, fatty acid synthase, ATP citrate-lyase, "malic" enzyme, and glucose-6-phosphate dehydrogenase. Glyceride synthesis was evaluated by determining the rate of incorporation of [14C]glycerol 3-phosphate into lipids. In addition, lipoprotein lipase activity was measured in acetone-ether powders of adipose tissue from the four groups of rats. In liver, training had no effect on fatty acid or glyceride synthesis in either group. However, aging caused a significant decrease in the activities of four of the lipogenic enzymes but had no effect on glyceride synthesis. Training caused an increase in fatty acid synthase and glyceride synthesis in adipose tissue, and aging decreased lipoprotein lipase activity. It was concluded that training enhances the synthetic capacity of lipids by adipose tissue but that aging had a more profound effect in that the activities of the enzymes involved in these processes were lower in the old rats. Furthermore, the decreased activity of lipoprotein lipase in the older rats may explain the higher plasma triglyceride levels that were observed in these animals.

Abstract:
The search for new stable and active catalysts of Fischer-Tropsch synthesis is one of the key directions for production of liquid fuels from alternative raw materials. Stabilization of the active phase is the main task in the development of catalysts for hydrogenation of CO into liquid fuels. This problem can be solved by choosing the optimal support, as well as the synthesis method. This work is devoted to the development of new polymer mono– and bimetallic Ru-containing catalysts for liquid phase Fischer-Tropsch synthesis. It is shown that the use of 1% Ru-HPS and 10% Co — 1% Ru-HPS allows to obtain a high yield of gasoline hydrocarbons (more than 70%), providing a high conversion of CO (up to 23%). The selected polymer-based systems showed high stability in the Fischer-Tropsch synthesis process.

Full text
Abstract:
The effects of N(omega-nitro-L-arginine (L-NNA), a nitric oxide synthase inhibitor, on airway responsiveness were studied in the spontaneously hyperresponsive Fischer and the control normoresponsive Lewis rat strains to investigate the role of the endogenous nitric oxide (NO) pathway in strain-related differences in airway responsiveness. Responsiveness to inhaled methacholine was significantly increased in L-NNA-treated Lewis rats but not in Fischer rats. L-NNA increased carbachol-induced tracheal contractions in vitro to a larger extent in Lewis rats compared with Fischer rats. The effect of L-NNA was abolished by removal of the epithelium. Carbachol induced a NO-dependent increase in guanosine 3′,5′-cyclic monophosphate levels in tracheal tissues but to a lesser extent in Fischer (2.1-fold increase) than in Lewis (3.7-fold increase) rats. In conclusion, endogenous NO is involved in the regulation of airway responsiveness to cholinergic agonists in rats. A relatively ineffective NO-guanosine 3′,5′-cyclic monophosphate regulatory mechanism in Fischer rats contributes, in part, to strain-related differences in airway responsiveness between Fischer and Lewis rats.

The effects of lanthanum promotion on cobalt based catalysts in Fischer-Tropsch synthesis were investigated. The Co/ZrO2 catalysts promoted by lanthanum had higher activity and selectivity in Fischer-Tropsch synthesis. The catalyst with the La content 1% had the highest activity and selectivity attributed to the promotion effect of La. However, excessive La addition could depress the activity of the catalyst due to the Co-La interaction and the lower reduction degree.

Abstract:
The aim of the article is to determine the properties of fuel mixtures of Fischer–Tropsch naphtha fraction with traditional gasoline (petrol) to be able to integrate the production of advanced alternative fuel based on Fischer–Tropsch synthesis into existing fuel markets. The density, octane number, vapor pressure, cloud point, water content, sulphur content, refractive index, ASTM color, heat of combustion, and fuel composition were measured using the gas chromatography method PIONA. It was found that fuel properties of Fischer–Tropsch naphtha fraction is not much comparable to conventional gasoline (petrol) due to the high n-alkane content. This research work recommends the creation of a low-percentage mixture of 3 vol.% of FT naphtha fraction with traditional gasoline to minimize negative effects—similar to the current legislative limit of 5 vol.% of bioethanol in E5 gasoline. FT naphtha fraction as a biocomponent does not contain sulphur or polyaromatic hydrocarbons nor benzene. Waste materials can be processed by FT synthesis. Fischer–Tropsch synthesis can be considered a universal fuel—the naphtha fraction cut can be declared as a biocomponent for gasoline fuel without any further necessary catalytic upgrading.

Abstract:
Steam methane reforming has been a conventional process to produce synthesis gas which is an important feedstock to many chemicals. However, for gas to liquid (GTL) applications this reforming process is not suitable as it produces synthesis gas with very high hydrogen to carbon monoxide ratio than required by the Fischer Tropsch synthesis in GTL line. In this work, a GTL process is designed in which synthesis gas is produced by steam reforming from a natural gas feedstock containing relatively substantial carbon dioxide contents in it. Synthesis gas composition is tailored by tail gas recycling from the Fischer Tropsch products. Process simulation and optimization is performed on Aspen HYSYS to produce synthesis gas with hydrogen to carbon monoxide ratio of 2 which is desired in GTL technology.

The prepared catalysts were characterized by using various techniques like BET (Brunauer–Emmett–Teller), SEM (Scanning Electron Microscopy), TGA (Thermal Gravimetric Analysis), XRD (X-ray diffraction spectroscopy), and FTIR (Fourier Transform Infrared Spectroscopy). Fixed bed micro reactor was used to test the catalytic activity of prepared catalysts. The catalytic testing results demonstrated the performance of hydrotalcite based cobalt catalyst in Fischer-Tropsch synthesis with high selectivity for liquid products. The effect of synthesis method on the activity and selectivity of catalyst was also discussed. Copyright © 2017 BCREC Group.

Abstract:
The effect of the preparation method of bifunctional cobalt catalysts with HZSM-5 zeolite and a boehmite binder on the catalytic performance in the Fischer–Tropsch synthesis was studied. The synthesized catalysts were characterized by means of BET, XRD, EDX, SEM, TEM, H2 TPD and NH3 TPD methods and tested in the synthesis of hydrocarbons at a pressure of 2.0 MPa, temperature 240 °C, and gas hourly space velocity 1000 h–1. It was shown that the method of catalyst preparation can be used for controlling the hydrocarbon and fractional composition ofproducts of the Fischer – Tropsch synthesis. A promising composite catalytic system for the single-step synthesis of low-freezing diesel fuel was proposed.

Abstract:
Previous studies in rat have demonstrated decreased number of mitochondria and uncoupling of oxidative phosphorylation after administration of glucocorticoids but at supraphysiological doses and using synthetic glucocorticoids. To analyze the relationships between corticosterone levels (the natural glucocorticoid in rat) and muscle mitochondrial metabolism, Lewis and Fischer 344 rats were bilaterally adrenalectomized and implanted with different corticosterone pellets (0, 12, 50, 100, and 200 mg of corticosterone). Rats bearing a corticosterone pellet delivering corticosterone at concentrations in the range of chronic stress-induced levels presented a lower amount of functional muscle mitochondria with a decrease in cytochrome c oxidase and citrate synthase activities and a depletion of mitochondrial DNA. Moreover, a strain difference in tissue sensitivity to corticosterone was depicted both in end-organ sensitive to glucocorticoids (body, thymus, and adrenal weights) and in muscle mitochondrial metabolism (Lewis > Fischer). Interestingly, this strain difference was also observed in the absence of corticosterone, with a deleterious effect on muscle mitochondrial metabolism in Fischer rats, whereas no effects were observed in Lewis rats. We therefore postulate that corticosterone is necessary for muscle mitochondrial metabolism exerting its effects in Fischer rats with an inverted U curve, whereby too little (only Fischer) or too much (Fischer and Lewis) corticosterone is deleterious to muscle mitochondrial metabolism. In conclusion, we propose a general model of coordinate regulation of mitochondrial energetic metabolism by glucocorticoids.
