    Selection in vitro for erucic-acid content in segregating populations of microspore-derived embryoids of Brassica napus (1995)
    Oxford, UK : Blackwell Publishing Ltd

    Notes: Microspore culture of Brassica napus under optimized conditions leads to the regeneration of microspore-derived embryoids that, at the late cotyledonary stage, contain large amounts of storage lipids, equal or similar in composition to those found in seeds of the homozygous donor plants. At that stage, the microspore-derived embryoids are large enough to allow the dissection of one cotyledon under aseptic conditions and the determination of its fatty-acid composition. The remaining part of the embryoid can be cultured further and regenerated to give a plant. This offers the possibility of early selection for fatty-acid composition in segregating populations of microspore-derived embryoids. In order to verify this hypothesis, embryoids were generated from microspores of F| plants derived from a cross between doubled haploid lines of the low-erucicacid cv. ‘Duplo’ and the high-erucic-acid cv. ‘Janetzki’. The contents of eicosenoic acid (C20: 1) and erucic acid (C22: 1) in the cotyledons and in the seeds derived from plants regenerated from the remaining parts of the embryoids were highly correlated (rs = 0.85**, P = 0.01). This indicates that, in breeding programmes for high erucic acid, the majority of the microspore—derived embryoids can be discarded at an early stage in vitro. Only microspore-derived embryoids with a high content of C20: 1+C22:1 in the cotyledons need to be transferred to the greenhouse. This report also deals with the addition of abscisic acid (ABA) to the embryoid culture medium to increase the correlation, and discusses the possible application of this system for the selection of high-oleic or low-linolenic types in corresponding microspore-derived embryoid populations.

    Immunohistochemical detection of tissue factor (TF) on paraffin sections of routinely fixed human tissue (1994)

    Notes: Abstract Tissue factor (TF), a 47 kDa transmembrane glycoprotein, is the essential receptor and cofactor for factor VII/VIIa. Its distribution in normal tissues and in tumours has been recently investigated immunohistochemically with monoclonal and polyclonal anti-TF antibodies in frozen sections. The cardinal problem of this technique is the difficulty of determining exactly the localization of the reaction product at least in certain tissues. Here, we demonstrate a method using monoclonal anti-TF antibodies to detect TF in routinely fixed, microwaved, paraffin-embedded tissues. Generally, there were no fundamental differences in TF distribution in frozen and paraffin-embedded material. However, in most cases, the paraffin sections allow a better cellular localization of TF. For example, the staining pattern for TF in both kinds of sections is identical in kidney, brain and skin. The paraffin-embedded material, however, clearly shows that TF expression is restricted to the parietal and the visceral epithelia of Bowman's capsule of glomeruli in the kidney, and to astrocytes and their processes in the brain. TF reactivity in the skin is revealed to be cell membrane-bound; in cardiomyocytes TF shows an exclusively sarcolemmal localization. The immunohistological detection of TF in paraffin sections is a powerful tool for systematic studies on the possible role of TF in the context of physiological and pathological studies.

    Growth and nitrogen fixation ofAeschynomene under water stressed conditions (1981)

    Notes: Summary Studies on the tolerance ofAeschynomene americana L. to periods of flooding or soil moisture deficit were conducted in an attempt to elucidate nitrogen fixation as affected by soil moisture. Nitrogenase activity was not reduced significantly in pot-grown Aeschynomene plants subjected to flooding in greenhouse conditions. After 20 days of withholding water from the soil, nitrogenase activities of the drought-stressed plants were much lower than those of either the well-watered or flooded plants. Leaf water potentials were similar in flooded and control plants; however, the droughted plants had leaf water potentials that were 4 bars lower than those of the control plants. Aeschynomene plants were tolerant to long-term periods of flooding, but exhibited a reduction in nitrogenase activity and leaf water status when subjected to soil moisture deficits.

    Pseudohalogen compounds of astatine: Synthesis and characterization of At/I/-tricyanomethanide-and At/I/-azide-compounds (1987)

    Notes: Abstract Reactions of At/⊖/+, “Ato.H2O”, AtCl 2 − and AtBr2 with the pseudohalogenides tricyanomethanide and azide are described. Information on the compound formation of astatine with C/CN/ 3 − and N 3 − could be obtained on the basis of electromigration investigations under variation of the conditions /composition of the electrolyte, pH, exchange reactions of ligands/. For the reaction: [At/H2O/C/CN/3]+C/CN/ 3 − ⇆[At/C/CN/3/2]+H2O at 301 K and u=0.075 mol.l−1 K2=/675±25/ [1.mol−1] and uo=−/3.50±0.10/×10−4 [cm2.s−1.V−1]. According to this astatine/I/-tricyanomethanide is classified between AtI 2 − and At/SCN/ 2 − . First investigations in azid-containing systems confirm the formation of astatine/I/-azide-compounds. Their composition is probably At/N3/ 2 − . There is no dependence of the ion mobility of astatine/I/-azide in the investigated range on azide concentration which is due to its high stability.

    Notes: We describe a new sensitive and specific method for determination of oxalate in human serum. By using the chemiluminescence decay of monoperoxyoxalic acid very low concentrations of oxalate (200 nmol/L) can be determined. The mean serum oxalate level in apparently healthy controls was 14.5 ± 8.5 m̈mol/L. Supplementation of ascorbic acid leads to an increase in serum oxalate level. While serum oxalate concentrations of calcium oxalate stone formers (x = 16.4 ± 9.8 m̈mol/L) are not significantly different from the control group, an extreme increase of serum oxalate is evident in haemodialysis patients. The serum oxalate concentration decreased during dialysis treatment from 141.4 ± 32.1 m̈mol/L to 36.4 ± 12.7 m̈mol/L.

    Description / Table of Contents: Comparison of the Reactivity of Triethyl Phosphorotrithioite and Triethylphosphite by Synthesis of P—N CompoundsTriethyl phosphorotrithioite, (EtS)3P, reacts unlike triethylphosphite with carbon tetrachloride and nitrogen containing nucleophiles. No reaction occurs with diester amides of phosphoric acid. When (EtS)3P is allowed to react with primary aliphatic amines not amides of phosphoric acid are obtained, but (EtS)2PCCl3 and EtSNHEt are yielded. In the reaction of (EtS)3P with (EtO)2P(O)H, CCl4, and NaN3 results the expected monophosphazene (EtO)2P(O)—N=P(SEt)3 only.The different nucleophilicity of phosphorus in (EtS)2P and (EtO)3P follows from CNDO/2-MO calculations, too.
    Notes: Bei der Reaktion mit CCl4 und stickstoffhaltigen Nucleophilen verhält sich das Triethyltrithiophosphit anders als das Triethylphosphit. Mti Phosphorsäurediethylesteramid und CCl4 setzt sich das Thiophosphit nicht um.Tetrachlormethan und primäre, aliphatische Amine bilden mit (EtS)3P nicht das Thiophosphorsäureamid, sondern (EtS)2PCCl3 und EtSNHEt.Nur bei der Umsetzung von (EtS)3P mit Diethylphosphit, Tetrachlorkohlenstoff und Natriumazid entsteht das erwartete Monophosphazen (EtO)2P(O)—N=P(SEt)3.Die unterschiedliche Nucleophilie des Phosphors im Trialkyltrithio- und Trialkylphosphit wird ausgehend von CNDO/2-MO-Berechnungen diskutiert.
