BACKGROUND: Khellin is a naturally occurring furochromone which, when combined with artificial ultraviolet (UV) A or solar irradiation (KUVA), is reported to repigment vitiligo skin as effectively as PUVA photochemotherapy. The exact mechanism of KUVA-induced repigmentation is unknown. OBJECTIVES: The aim of this study was to test the effect of khellin and KUVA on proliferation and melanogenesis of normal human melanocytes and Mel-1 melanoma cells in vitro. METHODS: Cultured normal human melanocytes, Mel-1 melanoma cells and fibroblasts were treated with khellin, UVA and KUVA and the effect on proliferation determined by cell counting. The effect on melanogenesis was determined by a radiometric melanin formation assay. Changes in gene expression and protein synthesis were determined by Northern blot, reverse transcriptase-polymerase chain reaction (RT-PCR) and Western blot analyses. RESULTS: Khellin stimulated proliferation of Mel-1 melanoma cells and melanocytes at concentrations between 1 nmol L-1 and
The medicinal plant Ammi visnaga is a valuable source of furanochromones and pyranocoumarins used as vasodilator agents. Its ability to germinate under unfavourable growth conditions, such as saline soil and hypoxia characterizing clay soils and marshes ecosystems, prompted us to qualitatively characterize secondary metabolites in umbels of A. visnaga plants grown under different conditions (in field, hydroponically controlled, and contrasted by salinity and/or hypoxia) by HPLC-ESI/IT/MSn analysis. Subsequently, the quantitative analysis of the bioactive compounds, above all furanochromones and pyranocoumarins, was carried out by HPLC-ESI/QqQ/MS/MS. The results show the influence of growing conditions on the quali-quantitative profile of A. visnaga secondary metabolites and evidence that hydroponic culture leads to increased level of A. visnaga active principles. Furthermore, two furanochromones never reported before were identified and characterized by 1D- and 2D-NMR analysis. ...
Considerable progress has been achieved in reducing aflatoxin contamination in agricultural products [47-52] since the discovery that aflatoxin is extremely toxic to humans and animals [2, 53]. Many inhibitors [9, 54] have been demonstrated to have an inhibitory effect on aflatoxin biosynthesis in A. flavus. Among them, plant-derived metabolites are of special interest. Non-host plant metabolites, such as onion, garlic extracts, eugenol [55-57], khellin, visnagin [58], caffeine, and piperlongumine [59] inhibit A. flavus growth and/or aflatoxin production. At the same time, host plant-derived metabolites including luteolin [60], eriodictyol [61], and tanning acids [62] also inhibit A. flavus development and/or aflatoxin production. However, most of these compounds can hardly be applied in practice because their biosynthesis pathway and the related biochemical steps are not well understood.. Resveratrol, a natural phytoalexin, could protect plants from fungal infection and improve the defense ...

Free radical oxidation (FRO) processes has been suggested to be the leading mechanism in the pathogenesis of lung diseases.. The aim was to study FRO processes in experimentally induced pneumonia (PN). Methods: PN was induced in 80 white rats by transthoracic injection of pneumococcus culture. The animals were sacrified before pneumococcus injection, and on the 1, 3, 7 days of PN. The content of malonic dialdehyde (MDA) was determined in the lung, liver and kidney tissues. The production of active oxygen forms (AOF) by alveolar macrophages (AM) was determined by nitroblue tetrazolium (NBT) test. Fe2+-induced chemiluminescence (ChL) of tissues and blood was recorded, morphological investigations were performed.. Results: MDA content in the lung of intact animals was lower than in other tissues. In the presence of Fe2+ in the lung tissue MDA value increased insignificantly and ChL was not observed. Addition of pulmonary homogenates to hepatic homogenate suppressed ChL and reduced MDA accumulation. ...
A study of the structural requirements of cholic acid derivatives as liver X receptor (LXR) ligands was performed. A model of cholenamide derivative 1 complexed with LXR showed that the C24 carbonyl oxygen forms a hydrogen bond with His435 located close to Trp457. The N,N-dimethyl group is located in a hydrophobic pocket. Based on these data, we designed compounds with high affinity for LXRs. Cholenamide derivatives 1-11 were synthesized from 3β-acetyl-Δ5-cholenic acid 20, and lactams 12-19 were synthesized from alcohol 25. Tertiary amides 3 and 4 showed higher activity in reporter assays, and compounds with hydrophobic residues exhibited the highest activity of all derivatives. The stereochemistry at C23 was found to be an important determinant of EC50 and gene transactivation, as each isomer exhibited different activity ...

Basidiomycetes isolated from rotted roots of alfalfa (Medicago sativa) and khella (Ammi visnaga) near Giza, Egypt, were evaluated for in vitro growth rates, temperature tolerance, pathogenicity, and similarity to isolates of Marasmiellus inoderma, a basidiomycete pathogen of maize and sugarcane in Egypt. All fungi produced similar white, appressed colonies on potato-dextrose, corn-dextrose, and malt agar media. Colony diameters indicated that the alfalfa and khella isolates were not identical; however, they were similar to those of M. inoderma. Growth of the alfalfa and khella isolates was similar to that of the M. inoderma isolates within the temperature range of 25 35 C, but below 20 C and at 38 C, development of the alfalfa and khella isolates was significantly greater than that of either isolate of M. inoderma. In pathogenicity tests, the alfalfa and khella isolates performed similarly but differently from either M. inoderma isolate on all hosts. Characteristics of basidiocarps of the ...

At normal atmospheric pressure oxygen melts at 54.36 Kelvin (K) and boils at 90.2 K; on Earth it essentially exists only as a gas. It readily dissolves in water, which makes aquatic life possible. Under normal conditions oxygen forms molecules consisting of two oxygen atoms each sharing two electrons in the 2p subshell; this form of oxygen is known as O2. O2 is a pale blue odourless gas. ...
The portion of oxygen consumed after exercise that removes excess lactic acid from the blood. A small amount of the excess lactic acid is excreted in urine and sweat; a little contributes to the manufacture of protein; some is converted to glucose or glycogen in the liver and muscle, but most of the lactic acid produced during exercise is reconverted into pyruvic acid and used in aerobic metabolism to form carbon dioxide and water. Approximately 5-10 L of oxygen forms the lactacid post-exercise oxygen consumption; it is usually higher in highly trained athletes, especially sprinters. ...

Due to its electronegativity, oxygen forms stable chemical bonds with almost all elements to give the corresponding oxides. Noble metals (such as gold or platinum) are prized because they resist direct chemical combination with oxygen, and substances like gold(III) oxide must be generated by indirect routes. Two independent pathways for corrosion of elements are hydrolysis and oxidation by oxygen. The combination of water and oxygen is even more corrosive. Virtually all elements burn in an atmosphere of oxygen or an oxygen-rich environment. In the presence of water and oxygen (or simply air), some elements- sodium-react rapidly, to give the hydroxides. In part, for this reason, alkali and alkaline earth metals are not found in nature in their metallic, i.e., native, form. Cesium is so reactive with oxygen that it is used as a getter in vacuum tubes, and solutions of potassium and sodium, so-called NaK are used to deoxygenate and dehydrate some organic solvents. The surface of most metals ...
The replacement of essential elements by heavy metals exercise an influence on phytoplankton ultrastructure and metabolism. When metals enter into the algal cells, they transform some biological ultrastructures, e.g. chlorophylls. Created metalo-biomolecules retain energy and block the electron transport chain. Increased generation of reactive oxygen forms is a result of abnormal metabolic activities and reactive oxygen species may cause a denaturation of biomolecules. Phytoplankton alleviates the toxicity of metals and oxidative stress through enhancing the defensive mechanisms. Production of phytochelatines is involved in the protection against the replacement of essential element by toxic metals. Antioxidants, such as superoxide dismutase, catalase, ascorbic acid, glutathione, and many peroxidases protect phytoplanktonic cells against oxidative stress ...

Atrial fibrillation is an abnormal heart beat that starts in the upper parts of the heart and can cause stroke or death, if untreated. In general, treatments are not very effective with frequent relapses of the abnormal heart beats. One explanation for the high relapse rate is that the treatments might not address the underlying cause of atrial fibrillation.. Recently, we have found that atrial fibrillation is associated with increased oxidative stress in a particular part of the top parts of the heart, the left atrial appendage (LAA). Oxidative stress is a condition where abnormal oxygen forms are produced. These forms harm the cells of the heart, causing them to beat abnormally. Also, the inside of the heart becomes sticky and more likely to form blood clots. These clots, when they travel to the head, are thought to be the main cause of stroke in this condition. We have found increased oxidative stress and increased evidence of blood clotting in pig and mouse models of atrial fibrillation. We ...

M ultiple environment trials (MET) are generally carried out by plant breeders to select and recommend high yielding and stable genotypes for a set of environments. The analysis of MET data often results in genotype - by - environment interactions which often causes difficulties in the interpretation of results and reduce efficiency in selecting the best genotypes . AMMI and GGE biplot analysis are two recent methods that are widely used to overcome these difficulties in MET data analysis. The objec tive of this study was to compare GGE biplot and AMMI analysis t hat determine the most efficient method for evaluating and describing genotype performance across environments .

Реферат: The preparation of model silver catalysts supported on highly oriented pyrolytic graphite is described, and the effect of the Ag particle size on the catalytic ethylene oxidation into ethylene oxide, studied by in situ XPS and mass spectrometry, is considered. For a mean particle diameter of 8 nm, the adsorbed oxygen species characterized by an O 1s binding energy of 530.8 ± 0.2 eV (electrophilic oxygen) forms on the silver surface exposed to the ethylene-oxygen reaction mixture. Larger silver particles with a mean diameter of 40 nm additionally contain the adsorbed oxygen species characterized by an O 1s binding energy of 529.2 ± 0.2 eV (nucleophilic oxygen). The presence of both oxygen species on the surface of the larger particles ensures the formation of ethylene oxide, while the sample with the smaller silver particles is inactive in the epoxidation reaction. The O 1s signal at 530.8 eV is partly due to oxygen dissolved in the subsurface layers of silve ...

The goal of this research was to assess the stability and yield performance of 150 durum wheat genotypes in multi-environment trials in two locations (Diyarbakir and Kiziltepe), in 2011-2012, and 2012-2013 growing seasons. The trials were designed by Lattice Experimental Design with two replications (incomplete block design). The AMMI (Additive Main Effects and Multiplicative Interaction) and GEI (Genotype×Environment Interaction) analysis were used in the study to estimate GEI effects on grain yield, because of plant breeders great interest in these models for breeding programs. AMMI evaluation indicated that genotypes made the most important contributions to treatments Sum of Squares (59.8%), environments (3.5%), and GEI (36.7%), respectively, suggesting that grain yield had been affected by environment. IPCA 1 and IPCA 2 axes (Principal Component) were significant as P| 0.01 and explained 63.8 and 36.2%, respectively. Results showed that Kiziltepe 2013 was more stable and high yielding, meanwhile
