Unterchungen über den Transport von Stoffen durch peritrophische Membranen / Investigation of the Transport of Material through Peritrophic Membranes
Authors: Zimmermann U. , Peters W. , Hallstein H. 
Published: March 2015

The tubular peritrophic membranes of Calliphora are formed by the secreting cells of the proventriculus at a rate of 3.5 ± 1 mm per hour. It has been estimated that each of these cells produces its own weight in membrane material in about one day.
Autoradiography of peritrophic membranes from flies injected with glucose-C 14 show cross bands as well as longitudinal bands, indicating a periodic incorporation of radioactive material and therefore a different chemical composition, which may be of importance for transport phenomena.

Authors: Tempel K. 
Published: March 2015

24 Stdn. bis 6 Wochen nach 3-mal im Abstand von 24 Stdn. wiederholter i.v. Injektion von Polyvinylsulfat (PVS), Pentosanpolysulfoester (SP54®) und Mucoitinpolysulfat (Heparin Novo®) in Dosen von 25,0 mg, 62,5 mg bzw. 12500 IE/kg K.-Gew. sowie 24 Stdn. nach 5-mal im Abstand von 1 Tag wiederholter i.v. Injektion von hoch- und niedrigmolekularer DNS in Dosen von 12,5 — 100 mg/kg wurde das Verhalten von Frischgewicht, DNS, Protein, DNase I und DNase II in Lunge, Thymus, Leber, Milz und Nieren der Maus untersucht.
Die wesentlichsten Ergebnisse lassen sich wie folgt zusammenfassen :
1. In Abhängigkeit von Polyanion und Dosis reagierte die Thymusdrüse hypo- oder hyperplastisch. Zu proliferativen Veränderungen kam es in Milz, Lunge, Leber und Niere.
2. Nach Heparinoidbehandlung blieb der Proteinbestand von Leber und Niere hinter dem gleichzeitig erfolgenden Zuwachs von Organgewicht und DNS-Gehalt zurück.
3. Unter dem Einfluß von PVS und SP54® verminderte sich die DNase I-Aktivität von Leber und Niere mindestens 4 Wochen lang um durchschnittlich 30 — 40 Prozent. Zu Aktivitätszuwachs kam es im Verlauf der DNS-Behandlung.
4. PVS und DNS führten in allen untersuchten Organen zu einem maximal 200-proz. Aktivitätszuwachs der sauren DNase.
5. Den Untersuchungen zufolge kommen Elemente des lymphoreticulären Gewebes als gemeinsamer Angriffspunkt von anionischen Makromolekülen in Betracht. Darüber hinaus lassen sich auch in vivo Wirkungen auf den Proteinstoffwechsel nicht ausschließen.
Mit Kohlensäure Verbundenes und Freies Chlorophyll.
Authors: Warburg Otto , Krippahl Günter , Lehmann Arnold 
Published: March 2015

Beweis, daß die Funktion des Chlorophylls bei der Photosynthese nicht nur die Absorption des Lichts ist, sondern auch die Umwandlung der Lichtenergie in chemische Energie. Chlorophyll ist also auch der chemische Katalysator der Photosynthese.
Der Beweis wurde erbracht durch Messung des verbundenen und des freien Chlorophylls während der Photosynthese sowie der O2-Entwicklung aus dem verbundenen Chlorophyll, deren Quantenausbeute = 1 ist und aus dem freien Chlorophyll, deren Quantenausbeute = 0 ist.
Spezifische Störung von Entwicklung und Enzymbildung der Plastiden höherer Pflanzen durch hohe Wachstumstemperaturen
Authors: Feierabend J. , Berger Ch. , Meyer A. 
Published: March 2015

1. At elevated growth temperatures between 32° and 34 °C synthetic processes of rye seedling plastids like formation of chlorophyll and photosynthetic enzymes (carboxydismutase) are nearly completely prevented, whereas formation of protein, of non-photosynthetic enzymes, and total leaf growth are little or not affected.
2. In the dark, carboxydismutase, which may be taken as representative of plastid behavior, fails to appear at 32°C, whereas it is normally synthesized at 22°C. Plastids of etiolated seedlings remain small at 32°C. Early formation of prolamellary bodies is normal but further differentiation of plastids cannot proceed as usual. They lack larger thylakoids, and ribosomes cannot be detected. But many osmiophilic globuli are accumulated, and characteristic tubulus like structures, which are not found at 22°C, appear in great number.
3. In light the ability of the seedlings to form chlorophyll sharply declines above 28°C. Between 32° and 34°C the leaves still reach full development but are rather chlorotic. Carboxydismutase remains extremly low in far-red as well as in red or blue light.
4. Carboxydismutase activity, which is already present, is not destroyed by high temperature, neither is the synthesis of this enzyme directly inhibited, if it is already proceeding. Maximum sensibility to the effect of high temperature is found in the youngest stages before the formation of photosynthetic enzymes has started.
5. Application of kinetin — alone or in combination with an auxin — does not restore formation of carboxydismutase at 32°C to normal rates of synthesis as observed at 22°C.
6. When seedlings are grown in 32°C between 24 and 96 hours of germination and then put back to 22°C the formation of carboxydismutase is not started again in the dark. But when they are kept in light after having been returned to 22°C a new increase of the enzyme as well as of chlorophyll is initiated.
7. The mode of action of high temperature is discussed. In many respects it corresponds to the well-known heat-bleaching effect of the unicellular alga Euglena.

Reaktionen von OH-Radikalen mit Acetaldehyd in wäßriger Lösung in Gegenwart von Sauerstoff / Reactions of OH-Radicals with Acetaldehyde in Oxygenated Aqueous Solution
Authors: Schultze Hartmut , Schulte-Frohlinde Dietrich 
Published: March 2015

γ-Irradiation of aqueous acetaldehyde in the presence of N2O and O2 at 0°C leads to the formation of 1.5 molecules of acetic acid per OH radical consumed. As intermediates peroxidic compounds are produced with a half life of about 50 min. H2O2 is not formed.
The primary step of the reaction is the interaction of the OH radical with acetyldehyde yielding water and acetyl radicals which add oxygen. The so formed acetylperoxy radicals form peroxidic intermediates which decompose to give oxygen, acetic acid, and peracetic acid. The peracetic acid interacts with additional acetaldehyde forming a peroxide that is converted into two molecules of acetic acid in a first order process.
At temperatures above 10°C, a chain reaction takes place leading to acetic acid with a G-value of 40 at 40°C. The propagating species are the acetylperoxy and the acetyl radicals. The reaction steps are addition of oxygen to the acetyl radicals and transfer of hydrogen from acetaldehyde to the acetylperoxy radical leading to peracetic acid. In this reaction no hydrogen peroxide is formed.

Authors: Bhushan Brij , Kar K. R. 
Published: March 2015

Sorption of ammine complexes of Cu2+, Ni2+, Zn2+ and Cd2+ on ferric phosphate has been studied at different ionic concentration in the external solution. It has been found that qA and Kd values attain a maximum with increasing concentration (0.02 ᴹ) beyond which a fall is observed. Selectivity quotients of the exchanger material towards competing pairs of the metal ammine ions e.g. (Cu(II)—Zn(II), Cu(II)—Cd(II) and Cu(II)—Ni(II) have also been measured as a function of the concentration of the external solution. The selectivity effects in general, decrease with increase in the external concentration. The qA and selectivity follows the same trend i.e.

Published: March 2015

Reaction of (NPCl2)2NSOCl or (NPCl2)2NSOF with benzene in the presence of AlCl3 yields (NPCl2)2NSOPh. By the same procedure two isomeric forms of NPCl2(NSOPh)2 can be obtained from cis-NPCl2(NSOCl)2. The phenylated products were characterized by IR, mass and 31P NMR spectra.
Reactions of one of the isomers of NPCl2(NSOPh)2 with (CH3)2NH yield NPClN(CH3)2(NSOPh)2 (molar ratio 1:2) and NP[N(CH3)2]2(NSOPh)2 (molar ratio 1:6.8). The structures of the amino substituted derivatives were determined by means of 1H NMR measurements.

α-D-Glucose and β-D-fructose were γ-irratiated in the solid (polycrystalline) state at room temperature at doses of 3.5 · 1020-4.2 · 1021 eV g-1 (dose rate 1.16 · 1018 eV g-1 min-1). Carbohydrate products containing ≤ 6 carbon atoms were identified and their G-values (in parentheses) measured.
Glucose: Dihydroxyacetone (1) (0.05), 3-deoxy-tetrose (2) (0.015), 1,4-dideoxy-2-pentulose (3) (0.05), 2,4-dideoxy-pentose (4) (0.085), 2,4-dideoxy-pentonic acid (5), 2,3-dideoxypentos-4-ulose (6) (together 0.035), threose (7), erythrulose (8), erythrose (9), erythronic acid (10) (together 0.04), 1-deoxy-2-pentulose (11) (0.005), 2-deoxy-ribose (12) (0.25), 3-deoxy-pentosulose (18) (0.02), 3,5-dideoxy-hexonic acid (14) (0.02), 2,3-dideoxy-hexonic acid (15) (0.01), arabinose (16) (0.25), ribose (17), ribonic acid (18) (together 0.02), 2-deoxy-2-C-hydroxymethyl-pentonic acid (19) (0.06), 5-deoxy-gluconic acid (20), 2deoxy-5-keto-glucose (21), 2-deoxy-gluconic acid (22), 2-deoxy-3-keto-glucose (28), 3-deoxy-glucosone (24), 3-deoxy-gluconic acid (25), 3-deoxy-4-keto-glucose (26), 3-deoxymannonic acid (27) (together 0.4). Identified but nor measured quantitatively were glucosone (28), 3-keto-glucose (29), 4-keto-glucose (30), 5-keto-glucose (31) and gluconic acid (82). G(H2) = 5.75; G(CO2) = 0.7.
Fructose: 7-9 (together 0.65), 3-deoxy-pentonic acids (37), 3-deoxy-pentosulose (88) (together 0.3), arabonic acid (89) (0.1), 18 (0.05), 6-deoxy-2,5-hexodiulose (40) (40). Identified but not measured quantitatively were glyceraldehyde (34), butanone-(3)-diol-(1,2) (35) and 2- and 3-deoxy-hexodiuloses. G(H2) = 4.75, G(CO2) = 0.05.
Reaction schemes are proposed to account for the formation of the products. The scission of the hemiacetal bond and of the C-Η and C-C bonds next to it appears to be typical for solid state irradiations. The formation of deoxy-compounds is observed both in the solid state and in aqueous solution. The formation of dideoxy-compounds is only prominent in the solid state. In polycrystalline fructose a chain reaction is induced leading to 6-deoxy-2,5-hexodiulose (40).
Ređuktone und Reduktonate, I Das Redoxpaar Dehydroascorbinsäure-Ascorbinsäure und ihre Anionen / Reductones and Reductonates, I The Redox Pair Dehydroascorbic Acid-Ascorbic Acid and Anions
Authors: Matusch Rudolf 
Published: March 2015

On the basis of NMR spectroscopy (1H and 13C) it can be shown that in water, dimethylsulfoxide and p-dioxane only the tautomer 1 of L-ascorbic acid is found in a measurable amount. Upon formation of the mono-anion la deprotonation occurs on the hydroxyl group attached to C-3; in addition the hydroxyl group on C-2 is deprotonated in case of the di-anion 1b. Both anions do not open the lactone ring.
After oxidation with iodine in aqueous solution only the dimer of dehydroascorbic acid is detected. This is hydrolized with a half-life of three hours to the monomeric dehydro ascorbic acid dihydrate 7. In dimethylsulfoxide the oxidation rate is decreased, and therefore the formation of the monomeric non-hydratized dehydroascorbic acid 10 can be monitored. This undergoes ringclosure relatively fast to give the half-ketal 13, the reaction of which via 14 leads to the optical active dimeric dehydroascorbic acid 6. The L-ascorbic acid acetonide 15 is oxidised by iodine to 16 which undergoes racemization via the enol 17 to give 18. This forms an equilibrium with compound 19.

Published: March 2015

TiCl4 and ZrCl4 were found to form a series of adducts with trimethyl(methylene)phosphorane, none of which is soluble in common inert solvents. With dimethylaminotitanium chlorides, a dinuclear ylide 10 was obtained, containing a dititanacyclobutane ring system, in which the metal atoms are bridged by [xxx] groups.
cp2TiCl2 and cp2ZrCl2 also form ylide adducts with (CH3)3P=CH2 in the ratio 1:2. The lithiated ylide converts both cp2TiCl2 and cp2TiCl into the cyclic ylide complex (C5H5)2Ti(CH2)2P(CH3)2 (13). With lithiated (CH3)3P=N–P(CH3)2=CH2, the related nitrido-bis-dimethylphosphoniummethylide derivative (15) could be isolated. 13 and 15 were characterized, inter alia by their ESR and mass spectra.

Abstract
The title complex was synthesised and its structure determined by x-ray crystallography. The structure contains two hydrogen bonds between the phosphoryl oxygen atom and the two meta-toluidinium ions. The P–N bond lengths are significantly different and the differences, attributed to varying p π-d π interactions along the bonds, confirm earlier observations on tri-para-toluidylphosphazenyl oxide.

The Influence of the Exchangeable Monovalent Cations on Vibrations of Y Zeolite Framework
Authors: Radak V. M. , Ćeranić T. S. , Živadinović I. M. 
Published: March 2015

Abstract
The influence of the exchangeable monovalent cations on the vibrations of the frame-work of Y zeolite has been studied. A regular shift of the frequencies of some absorption bands is observed and described as a function of interaction between the exchangeable cation and the oxygen from the zeolite framework. The linear dependence of the fre-quencies of some absorption bands and the reciprocal of the sum of ionic radii of the cation and the framework oxygen suggests that the exchanged cations: Na+ , Ag+, K+ and Tl+ are occupying similar positions in the zeolite lattice. Li+ and Cs+ ions do not obey this regularity. The present IR studies agree with the results of chemical analysis of the studied zeolites.
