Phospholipid patterns of 15 representative strains of the genus Amycolatopsis were recorded by two-dimensional thin-layer chromatography. The structure analysis of the isolated phospholipids was verified by fast atom bombardment-mass spectroscopy. The positive- and negative-ion spectra of the partially purified phospholipid fractions qualitatively reflect their distinctive composition. All strains contained diphosphatidylglycerol, phosphatidylglycerol, and phosphatidylinositol. Two different types of phosphatidylethanolamine and phosphatidylmethylethanolamine were detected, viz., compounds with or without hydroxy fatty acids. These phospholipid patterns underline the integrity of the genus. Fast atom bombardment-mass spectrometry analysis of phospholipid patterns may serve as an aid for differentiation of bacterial species.
Annes initial forays into mass spectrometry for glycopolymer analysis were stimulated in 1979 by a sabbatical visit to Imperial by Clint Ballou, Chair of Biochemistry at Berkeley. Together, they undertook pioneering work revising the structure of the 6-O-methylglucose polysaccharide of Mycobacterium smegmatis utilizing field desorption and fast-atom bombardment mass spectrometry. A few years later, her research on leukocyte glycosylation with Minoru Fukuda at the La Jolla Cancer Research Foundation was fundamental to the emerging field of glycobiology, laying foundations for studies into the roles of carbohydrates in the immune system. A seminal discovery was her identification of sialyl-Lewis X on neutrophils, pivotal to defining ligands for the selectins when they were cloned in 1989. Annes characterization of the glycoprotein hormone that controls erythropoiesis (erythropoietin) in the late 1980s was crucial for biopharmaceutical progress, as it provided the first evidence the recombinant ...

|p|Liquid state, high resolution 13C NMR spectroscopy and mass spectrometry were used to study the composition and structure of soil organic matter (SOM) using soil extracts from two long-term experiments at the Rothamsted Experimental Station. Both one- and two-dimensional NMR techniques were applied. 13C NMR sub-spectra of the CHn (n=0...3) groups, obtained by the Distortionless Enhancement by Polarisation Transfer (DEPT) technique, were used for the elucidation of the qualitative and quantitative composition of humic and fulvic acids in the soils. The chemical structure of SOM was further analysed at the molecular level through Fast Atom Bombardment Mass Spectrometry (FABMS) and Gas Chromatography-Mass Spectrometry (GC/MS). Humic and fulvic extract results were not only compared to each other, but also to the solid state 13C NMR results for the complete soil sample.|/p|
A novel glutathione-conjugated metabolite of morphine has been isolated from the bile of guinea pigs given morphine. The metabolite was separated by preparative HPLC on a reverse phase column (YMC-GEL C18) using methanol/water (1:4, v/v) as eluate and purified by HPLC on another reverse phase column (mu-Bondapak phenyl) using water/acetonitrile/trimethylamine/acetic acid (150:3:2:1, v/v) as a mobile phase. The unambiguous structure assignment of the metabolite was performed by fast atom bombardment mass spectrometry and 400 MHz fourier transform NMR spectrometric analysis, and it was identified as (8S)-glutathion-S-yl)dihydromorphinone, in comparison with the synthetic morphinone-glutathione adduct. ...
As a simple model of ultraviolet (UV)-induced protein denaturation, Amyloid P hexapeptide (APH, Phe-Thr-Leu-Cys-Phe-Arg) was exposed to UVA irradiation. A new product was isolated by HPLC and identified by fast atom bombardment mass spectrometry (FAB-MS) as the disulfide dimer. Thus, UVA induced disulfide bond formation. We also examined the effect of replacing the Cys residue of APH with other amino acid residues (methionine, tryptophan, tyrosine and histidine) that might be susceptible to oxidative damage. In the case of [Trp4]-APH, the amount of the analog was decresed at 40 J/cm2 or higher. When APH and [Trp4]-APH were mixed and UVA-irradiated, the combination afforded a greater number of products than the sum of those obtained when they were separately irradiated. That finding suggests that denaturation of proteins by UVA may involve very complex reactions of plural kinds of amino acid residues. Since the UV-induced APH dimer formation could be easily evaluated by HPLC, we used this system ...

Major expansion of newborn screening for inherited metabolic disorders is taking place across the US and around the world as newer analytical technology is applied. Historically, each disorder to be screened required a separate test with associated costs and requirement for a portion of the dried-blood-spot specimen from a heel stick. This limitation of the existing tests was partially responsible for the limitation of mandated newborn screening in the US to a small number of disorders (usually three to seven, depending on the state).. The technique of tandem mass spectrometric (MS) analysis of dried-blood spots was first proposed for newborn screening in 1990 by Millington et al. (1). Using ionization techniques of fast atom bombardment or liquid secondary ionization with tandem MS, they simultaneously determined a large number of acylcarnitines as an acylcarnitine profile. This allowed newborn screening for numerous inherited fatty acid oxidation and organic acid disorders by a single ...
Ions as a source of reactants: Ions get neutralized when they reach the surface, they become an additional source of reactive species.. The synergy between ion bombardment and chemical etching was first shown by Coburn and Winters in the classical experiment shown on slide 2.. Besides enhancing the chemical etch, ions also play a major role in removing non-volatile by-products or etch products that require an activation energy to desorp from the surface. The removal of by-products and their redeposition onto the feature sidewall is the fundamental reason why plasma etching can obtain anisotropic profiles (slide 3). Factors that influence the anisotropy are (slide 4 ...

The amino acid sequence of human alpha-fetoprotein, a 67-kDa protein present in mammalian embryonic serum, was verified by fast atom bombardment mass spectrometric (FAB/MS) analyses of three different enzymatic digests of the protein. Human alpha-fetoprotein obtained from a large-scale cell culture was digested with trypsin and V-8 protease either separately on two different samples or combined on the same one. The V-8 protease digest of the protein was partially fractionated by HPLC; the other samples were directly analyzed by FAB/MS without previous purification steps. About 90% of the alpha-fetoprotein amino acid sequence was verified by mass spectrometric analysis; this also confirmed that the cell-derived protein is identical with the hepatoma-derived protein. FAB analysis revealed that the N terminus of the mature protein is arginine rather than threonine, with the threonine occupying the second position. Therefore, the processing site of the alpha-fetoprotein signal peptide during maturation of
TY - JOUR. T1 - A revised biosynthetic pathway for phosphatidylinositol in Mycobacteria. AU - Morii, Hiroyuki. AU - Ogawa, Midori. AU - Fukuda, Kazumasa. AU - Taniguchi, Hatsumi. AU - Koga, Yosuke. PY - 2010/11/1. Y1 - 2010/11/1. N2 - For the last decade, it has been believed that phosphatidylinositol (PI) in mycobacteria is synthesized from free inositol and CDP-diacylglycerol by PI synthase in the presence of ATP. The role of ATP in this process, however, is not understood. Additionally, the PI synthase activity is extremely low compared with the PI synthase activity of yeast. When CDP-diacylglycerol and [ 14C]1L-myo-inositol 1-phosphate were incubated with the cell wall components of Mycobacterium smegmatis, both phosphatidylinositol phosphate (PIP) and PI were formed, as identified by fast atom bombardment-mass spectrometry and thin-layer chromatography. PI was formed from PIP by incubation with the cell wall components. Thus, mycobacterial PI was synthesized from CDP-diacylglycerol and ...

We have previously described the structures of neutral and sialylated O-glycosidic mannose-linked tetrasaccharides and keratan sulphate polysaccharide chains in the chondroitin sulphate proteoglycan of brain. The present paper provides information on a series of related sialylated and/or sulphated tri- to penta-saccharides released by alkaline-borohydride treatment of the proteoglycan glycopeptides. The oligosaccharides were fractionated by ion-exchange chromatography and gel filtration, and their structural properties were studied by methylation analysis and fast-atom-bombardment mass spectrometry. Five fractions containing [35S]sulphate-labelled oligosaccharides were obtained by ion-exchange chromatography, each of which was eluted from Sephadex G-50 as two well-separated peaks. The apparent Mr values of both the large- and small-molecular-size fractions increased with increasing acidity (and sulphate labelling) of the oligosaccharides. The larger-molecular-size fractions contained short ...

Alpha, beta, and gamma radiation also accompany induced radioactivity. Radioactive isotopes are prepared in the lab using bombardment reactions to convert a stable nucleus into one which is radioactive. Positron (particle with the same mass as an electron, but a charge of +1 instead of -1) emission isnt observed in natural radioactivity, but it is a common mode of decay in induced radioactivity. Bombardment reactions can be used to produce very heavy elements, including many which dont occur in nature ...

A major metabolite of [3H]ecdysone injected into adults of the nematode Parascaris equorum maintained in vitro for 48 h was secreted into the culture medium. The compound could be hydrolysed with a crude hydrolase preparation from Helix pomatia, yielding ecdysone. Sufficient quantity of this material for identification was produced by administration of ecdysone to the parasites. The resulting compound was purified by h.p.l.c. and identified as ecdysone 25-O-beta-D-glucopyranoside by n.m.r. spectroscopy and by fast atom bombardment mass spectrometry of the conjugate and of the sugar released by enzymic hydrolysis. The significance of formation of the glucoside is uncertain. ...

Berninamycins B, C, and D were isolated by reverse-phased HPLC from S.bernensis. The structures of berninamycins B and D were studied with $\sp{13}$C NMR and FAB mass spectrometries. Berninamycin B was found to be deoxyberninamycin A with a valine unit instead of the $\beta$-hydroxyvaline unit of berninamycin A. Berninamycin D was found to have two less dehydroalanine units attached to the carboxyl carbon of the pyridine ring moiety. The structure of berninamycin C was postulated to have one less dehydroalanine unit attached to the carboxyl carbon of pyridine based on FABMS result. The biogeneses of these minor metabolites were discussed ...

This dissertation explores innovations in index-based risk transfer products (IBRTPs) as a means to address an important insurance market failure that leaves many poor and vulnerable populations exposed to considerable uninsured risk. IBRTPs can address problems of covariate risk, asymmetric information and high transaction costs that have precluded the emergence of formal insurance market in low-income areas, where uninsured risk remains a leading cause of persistent poverty. A brief introductory chapter situates this dissertation in the broader, emergent literature on IBRTPs. The second chapter explains how the strong relation between widespread human suffering and weather shocks creates an opportunity to develop famine indexed weather derivatives to finance improved emergency response to humanitarian crises. The third chapter explains how these instruments might be designed and used by operational agencies for famine prevention in response to slow-onset disasters. It uses household data to ...

p,Administration of phenylhydrazine to rabbits resulted in the denaturation of hemoglobins in erythrocytes, causing the formation of intracellular precipitates known as Heinz bodies, severe hemolytic anemia, and reticulocytosis. To elucidate the molecular mechanism of the destabilization, we allowed human oxyhemoglobins to react aerobically with phenylhydrazine. After treatment with acetic acid/HCl and H2SO4/methanol, the chloroform extract contained blue-green pigments of major products accompanied by different minor products. Each product was isolated by column chromatography. By fast-atom-bombardment mass spectrometry (FAB-MS) and proton nuclear magnetic resonance (1H-NMR) spectrometry, dimethyl esters of N-phenylprotoporphyrin IX and meso, N-diphenylprotoporphyrin IX were determined. Other major products also were determined to be dimethyl esters of triphenyl-and tetraphenyl-substituted protoporphyrins by FAB-MS. The formation of meso, N-diphenylprotoporphyrin indicated that the addition of ...

The collision induced decompositions of 3-substituted adamantane carboxylate anions have been studied with a view to uncovering charge-remote fragmentations of the 3-substituent. The 3-substituent is chosen so that it cannot approach the anion site, and so any fragmentations of that substituent should proceed independently of the charged centre, viz. charge-remote reactions. The following systems have been studied (i) the 3-cyclohexenyl system shows no charge-remote retro Diels-Alder fragmentation (DeltaH = +157 kJ mol(-1)), instead, charge-remote loss of the cyclohexenyl radical is noted, (ii) the 3-isobutyl ketone system shows no Norrish II cleavage (loss of C(3)H(6), DeltaH = +18 kJ mol(-1)), instead, the competitive losses of CO(2) from the charged carboxyl centre, together with charge-remote radical loss of the 3-substituent are observed, and (iii) the corresponding 3-isopropyl ester does show the Norrish II loss of C(3)H(6), together with competitive losses of CO(2) and the ...

The battery Sergeant-Major was practically asleep. He was all worn out by the continuous roar of bombardments that had been shaking the dugouts and dazing his brains for weeks. He was pretty well fed up.. The officer commanding the battery, a young man in a very neat uniform and of particularly high birth, came up and spat in his face. The Sergeant-Major sprang to attention, received an order, and took a stick at once and beat up the tired men. For a message had come to the battery that some English (God punish them!) were making a road at X.. The gun was fired. It was one of those unlucky shots that come on days when our luck is out. The shell, a 5.9, lit in the midst of the British working party. It did the Germans little good. It did not stop the deluge of shells that was breaking up their guns and was driving misery down like a wedge into their spirits.

Extraction and isolation. The air-dried medullae of J. effuses (6 kg) were powdered and extracted with 95% ethanol (3 × 70 L) at room temperature. The extracts were combined and concentrated under vacuum to give a residue (180 g). The residue was subjected to column chromatography over a silica gel (200-300 mesh), eluted with petroleum ether-acetone (from 10:1 to 1:1) to generate fractions 1-5. Fraction 2 (2.8 g) was subjected to medium pressure silica gel column chromatography eluted with petroleum ether-ethyl ether-acetone (20:2:1) to yield three fractions 2-1 to 2-3. Fraction 2-2 (1.21 g) was subjected to medium pressure silica gel column chromatography eluted with petroleum ether-acetone (30:1) to afford six fractions 2-2-1 to 2-2-6. Fraction 2-2-2 (860 mg) was subjected to silica gel column chromatography eluted with petroleum ether-acetone (40:1) to yield five fractions 2-2-2-1 to 2-2-2-5. Fraction 2-2-2-5 (600 mg) was chromatographed on Sephadex LH-20 (petroleum ether-CHCl3 -MeOH, ...

Mixed ligand complexes of Zn(II) and Co(II) with cysteine, histidine, cysteinemethylester, and histidinemethylester have been synthesized and characterized by elemental analysis, conductivity, magnetic susceptibility measurements, and infrared,1H NMR, TGA and FAB mass spectra. In these complexes, histidine, and histidinemethylester act as bidentate ligands involving amino and imidazole nitrogens in metal coordination. Similarly, cysteine, and cysteinemethylester also act as bidentate ligands coordinating through thiol sulphur and amino nitrogen. Tetrahedral geometry has been proposed for Zn(II) and Co(II) complexes based on experimental evidence.. ...

The peculiarities of sputtering processes at low-energy Ne grazing ion bombardment of Si(001), SiC(001) and Cu3Au(001) surfaces and their possible application for the surface modification have been studied by computer simulation. Sputtering yields in the primary knock-on recoil atoms regime versus the initial energy of incident ions (0.5-5 keV) and angle of incidence (0-30 degrees) with respect to the target surface have been calculated. It was shown that in the case of grazing ion bombardment, the layer-by-layer sputtering is possible, and its optimum is observed within the small angular range of the glancing angles near the threshold sputtering angle. Comparative studies of layer-by-layer sputtering for Si(001) and SiC(001) surfaces versus the initial energy of incident ions as well as an effective sputtering and sputtering threshold are discussed.

the French had brought with them. They sailed about g p.m., General Béthouart accompanying Lord Cork in the Effingham. The battleship Resolution and a second cruiser, the Aurora, would give weight to the bombardment. There were also five destroyers, one of which (the Havelock) had mounted a French mortar battery on the forecastle. The foremost landing party of 120 men made the twenty-mile passage to Bjerkvik in the four assault landing craft; the rest of the 1,500 infantry mainly in the two cruisers, each of which drew a ready-made-up tow, consisting of a power boat and two pulling boats, behind her. The tanks were carried in the battleship, together with two motor landing craft for putting them ashore; a third, which was of a more modern type, went under its own steam. The whole was to be covered by aircraft from the Ark Royal. The original plan had provided that there should be no preliminary bombardment if there was a possibility of surprise, but in the end the leading destroyers had ...

You know - this bin Laden character was relegated to Elvis/ Jimmy Hoffa status in the Islamic terrorist and liberal circles - these two groups sincerely want to belief that the old fart is still alive, and those grainy audio-tapes Islamics try to produce to proof the latter seem to be a perfect sell to liberals. Cmon, the guy is dead and buried, get over it, it is most likely he was killed in 2002 Tora Bora air bombardment - and he is nothing but a Big Brother type character for anti-Americans like Islamic fundies and libturds ...

During the pacification of the traitor turned world of Nolec Trinus, the Imperial forces bombarded the northern continent with twenty thousand artillery batteries. This was able to stop most of the enemy forces, but some hid in deep bunkers. Finding a demon in the form of a twisted dragon with tentacles, Knight-Errant Nathaniel Garro traveled alone through the bombardment to battle it. After Garro disappeared and broke vox contact, Fellow Knight-Errant Helig Gallor and a squad of regular soldiers serving Malcador the Sigillite went in search of him. They found Garro resting upon his sword next to a destroyed basilica once built by the Word Bearers. Behind Garro was the corpse of the demon, dead. Gallor tried to speak to Garro, but Garro rebuffed him, listening for something.[1] Being ignored upset Gallor, and he pushed Garro further into speaking, saying that he was told by the Sigillite to determine why Garro did not respond. Garro explained that his helmet was ruined by acid, and that he could ...

Hans was a busy, happy, sweet and fearless three year old when he was diagnosed with Neuroblastoma. He fought his disease like a "gladiator" for nearly 6 years. Hans was an animal lover to his core. He was guarded at home by his three cats, Black, Orange and Cotton. He also had his Golden Retriever, Honey, to keep him company. Hans enjoyed swimming, biking, gardening, grilling (he had his very own grill!), horseback riding, playing video games, building Legos, and flipping between Nickelodeon, Cartoon Network and Animal Planet. Hans loved all members of his family and he was a loyal friend. He had to go through a lot of treatment in his life. But Hans powered through it. His attitude was lets get this done! His motivation was always to get back home, to his family, pets, favorite foods and pool ...
The methanol fraction (165 g) was separated by silica gel column chromatography and eluted with CHCl3-MeOH mixtures of increasing polarity (100:1→20:1) to afford 10 fractions (Fr. 1~10). Fraction 4 was purified by Sephadex LH-20 column chromatography using MeOH-Water (9:1) to produce compound 5. Fraction 6 was separated on a Sephadex LH-20 column chromatography with MeOH-Water to generate 8 subfractions (Fr.6-1~Fr.6-2). Fraction 6-5 was separated by silica gel column chromatography and eluted with CHCl3-acetone mixtures to afford 18 subfractions (Fr.6-5-1~Fr.6-5-18). Subfraction 6-5-6 was re-crystallized from MeOH to afford compound 7. Fractions 8 and 9 were recrystallized from MeOH to afford compound 6 and compound 1. The remaining fraction 9 was separated using a Sephadex LH-20 column chromatography with MeOH-Water to generate 8 subfractions (Fr.9-1~Fr.9-8). Fraction 9-8 was recrystallized from MeOH to afford compound 2. Fraction 9-6 was further purified by semi-preparative reverse-phase ...
Resonances in the yield of ground-state protons from alpha-particle bombardment of 31P were investigated in the energy range Eα = 1.7 − 3.3 MeV. Fourteen resonances were observed, none of which was known before. Resonance energies and strengths are presented. Angular distribution measurements lead to unique values of the resonance ... read more spin in all cases but one. The exception is the strong resonance at Eα = 3.302 MeV, which shows a deviation from forward-backward symmetry in the angular distribution, to be explained by assuming interference with some unknown broad resonance(s) with opposite parity, probably at higher energy. show less ...
A thermal and chemical degradation approach was followed to determine the precursors of pristane (Pr) and phytane (Ph) in samples from the Gessoso-solfifera, Ghareb and Green River Formations. Hydrous pyrolysis of these samples yields large amounts of Pr and Ph carbon skeletons, indicating that their precursors are predominantly sequestered in high-molecular-weight fractions. However, chemical degradation of the polar fraction and the kerogen of the unheated samples generally does not release large amounts of Pr and Ph. Additional information on the precursors of Pr and Ph is obtained from flash pyrolysis analyses of kerogens and residues after hydrous pyrolysis and after chemical degradation. Multiple precursors for Pr and Ph are recognised in these three samples. The main increase of the Pr/Ph ratio with increasing maturation temperature, which is associated with strongly increasing amounts of Pr and Ph, is probably due to the higher amount of precursors of Pr compared to Ph,...
This study has demonstrated that microparticle bombardment is a simple and efficient technique for generating stable transgenic lines in C. elegans. We have found that a substantial proportion of the transgenic lines generated by microparticle bombardment contain a low number of copies of the transforming DNA integrated into a chromosome, resulting in stable transmission of the transgenic DNA over many generations. A critical factor in the success of this microparticle bombardment transformation strategy is the use of a selectable cotransformation marker to identify rare transformed animals within the population of bombarded animals and their descendants. For the experiments described in this article, we bombarded unc-119 mutants with plasmids containing an unc-119 rescuing fragment and were able to identify transformed animals based on their ability to survive starvation and on their non-Unc phenotype.. In some cases, the unc-119 gene may be an unsuitable cotransformation marker due to ...

How can I complain about lack of ideas to start up my own creativity? It is easier to become discouraged by the volume of other peoples past creativity, and question the worth of your own ideas. I have amazing access to so many images and ideas, from all of history and nature, information from many cultures other than the one I grew up in... wow! How easy it is to become numb to the bombardment of information, and how difficult it can be to see that ones own creativity is a contribution to something, rather than just a re-iteration of what has already been done. Even the commercials are so complex, artistic in many ways, and culturally revealing. How do you start, when you feel like what you may have to say is insignificant ...
