    Notes: Abstract Tay's syndrome is a trichothiodystrophy associated with congenital ichthyosis. We report the findings on MRI and spectroscopy in a young girl with sparse, short, ruffled hair, dry skin and delayed milestones. T2-weighted images showed prominent diffuse confluent increase in signal symmetrically in all the supratentorial white matter. These findings are similar to those in a previously described case, and consistent with dysmyelination. Spectroscopy showed increased myoinositol and decreased choline.

    Lithium niobate: Summary of physical properties and crystal structure (1985)
    Springer
    Applied physics 37 (1985), S. 191-203

    ISSN: 1432-0630

    Notes: Abstract Ferroelectric lithium niobate (LiNbO3) is widely used in integrated and guided-wave optics because of its favorable optical, piezoelectric, electro-optic, elastic, photoelastic, and photorefractive properties. However, detailed summaries of its pertinent physical properties and crystal structure are not readily available. In this tutorial paper, the important tensor physical properties and their mathematical descriptions are compiled and presented. The essential features of the structure of lithium niobate, including its hexagonal and rhombohedral unit cells, are illustrated and the principal (Cartesian) axes used in the description of the anisotropic properties are specified relative to the crystal structure. Errors in property coefficient values and structure information that have been propagated in the literature are corrected.

Diese wurden alkyliert und zu 6-Methylthio-1-phenyl-2,3-dihydro-4(1H)-pyridinonen (5) hydrolysiert. Zuletzt gelangte man durch selektives Entfernen der Methylthiogruppe mitRaney-Nickel zu den Titelverbindungen6.

    Notes: Summary 6-Phenylimino-3,6-dihydro-2H-thiopyran-4-amines (1) were converted to 1-phenyl-5,6-dihydropyridine-2(1H)-thiones (3). Those were akylated and hydrolyzed, thus yielding 6-methylthio-1-phenyl-2,3-dihydro-4(1H)-pyridinones (5). Finally, the methylthio group was removed withRaney nickel giving the title compounds6. The relative configurations of the formed diastereoisomeric dihydropyridinones have been investigated by NOE measurements.

    Notes: Summary 3-Amino-2,4-pentadienthioamides, which were obtained from 6-dialkylamino-2H-thiopyrane-4(3H)iminium halides by alkali hydrolysis, react with hydroxylamine hydrochloride in a [C-C-C] + [N-O]-addition to give selectively 5-amino-3-alkenyl-1,2-oxazoles. These oxazoles have been identified by13C and1H NMR spectroscopic analysis. The configuration of these compounds was established on the basis of the coupling constants and 2D-NOESY-experiments. The position of the substituents has been determined by analysis of the fragmentation pattern.

Die Umsetzung mit Ammoniak führte zur Bildung von 6-Dimethylamino-2H-thiopyran-4(3H)-iminiumiodiden (3). Diese wurden zu 3-Amino-N,N-dimethyl-2,4-pentadienthioamiden (4) hydrolysiert. Beim Erhitzen mit Schwefel erfolgte Cyclisierung zu 3-Aminothiophen-2-thiocarboxamiden (5). Die Konfiguration der Pentadienthioamide (4) wurde mit NOE-Messungen untersucht, die der Thiophen-2-thiocarboxamide (5) mit Hilfe zweidimensionaler NMR-Methoden aufgeklärt.
    Notes: Summary 4-Dimethylamino-5,6-dihydro-2H-thiopyran-2-thiones (1) were alkylated to N,N-dimethyl-6-methylthio-2H-thiopyran-4(3H)-iminiumiodides (2). Aminolysis of the latter with ammonia led to 6-dimethylamino-2H-thiopyran-4(3H)-iminiumiodides (3) which were hydrolyzed to 3-amino-N,N-dimethyl-2,4-pentadienthioamides (4). Ring closure with sulfur gave 3-aminothiophene-2-thioamides (5). The configurations of the pentadienthioamides (4) have been investigated by NOE experiments. The structures of the thiophene-2-thioamides (5) were established by means of two-dimensional NMR techniques.

    Description / Table of Contents: Zusammenfassung Es wurde der Einfluß von 3 Aminosäuren-Kohlenhydrate-Komplettlösungen (1. TPE 1800 Pfrimmer,n = 12; 2. Combiplasmal, Braun-Melsungen,n = 12; 3. AKE 2000 Fresenius,n = 12) auf die Magensekretion untersucht und dabei mit einer Kontrollgruppe verglichen (0,9 % NaCI,n = 12). Ergebnisse: Volumen: keine signifikante Abweichungen. Säure-Gesamt, Säure-Konzentration und Pepsin-Gesamt zeigen einen signifikanten Anstieg. Gastrin: Keine signifikanten Veränderungen. Blutzucker und Insulin: sind bei Lösung 2 signifikant erhöht. Die stimulierte Magensekretion kann durch Cimetidin und Pirenzepin supprimiert werden.
    Notes: Summary The gastric secretory response to three amino acid-carbohydrate solutions (I. TPE 1800 Pfrimmer,n = 12; 2. Combiplasmal, Braun- Melsungen,n = 12; 3. AKE 2000 Fresenius,n = 12) was examined and compared to that of controls (0.9 % NaCI,n = 12). Results: Acid and pepsin outputs: significantly stimulated, no significant change of gastric volume. Gastrin : does not mediate this secretory response. Insulin and blood sugar: significantly elevated by solution 2. Cimetidine and pirenzepine inhibit this stimulated gastric secretion.
