    Pressure and light effects on the phase transition of deuterated Cu(2,5-dimethyl-dicyanoquinonediimine)2 (1996)

    Notes: The deuterated dicyanoquinonediimine salt Cu(2-CD3,5-CD3-DCNQI)2, (d6), a highly conductive organic metal, exhibits a phase transition from the metallic to the insulating state at Tc≈60 K. In a wide temperature range we observe an anticoincidence of high conductivity and electron spin resonance (ESR). These experiments were performed simultaneously in our ESR apparatus equipped for application of He pressure up to 200 bar. Near Tc there is a coexistence of conducting (ESR-silent) and insulating (ESR-detectable) domains. This correlation of ESR and conductivity σ points to a percolation limited conductivity. Upper and lower limits of the size of the domains are given. Light shifts Tc to lower temperatures, pressure to higher ones. This could be due to shrinking of the lattice which induces the phase transition when critical structural parameters are approached. This is most probably explained by a simultaneous development of a charge density wave (CDW) and a spin pairing within the DCNQI stack together with the trimerization of the lattice. Systematic measurements by variation of temperature, pressure, and light led to phase diagrams of (d6) and to the understanding of the mechanism of the phase transitions. © 1996 American Institute of Physics.

    Notes: Bush beans, kale and soybeans were used as models for studying the effects of processing by canning and freezing upon 51Cr and 65Zn content. Plants were grown hydroponically, intrinsically labeled with 51Cr and 65Zn, and processed either by canning or freezing. Freezing resulted in 65Zn losses of 10.7% for kale, 8.6% for bush beans, and 6.7% for soybeans. A loss of 3.8% of 51Cr resulted during freezing of bush beans. Canning resulted in 65Zn losses of 23% for kale, 19.7% for bush beans, and 28.8% for soybeans. Canned bush beans and kale contained 40.7% and 62.7% respectively, less 51Cr than unprocessed samples. Freezing resulted in a greater mineral retention than canning. Less opportunity for leaching is available in freezing and reduction in radionuclide content of the vegetables by canning was accounted for by transfer to the drained liquid.

    Notes: 1. The interactions between five α-adrenoceptor blocking agents and clonidine have been studied in rats, rabbits and dogs after intracisternal injections.2. Dibozane, ethomoxane, azapetine, dibenamine and thymoxamine reduced blood pressure in rats and an antagonism of the hypotensive effects of clonidine was detected for the first four drugs.3. In rabbits, azapetine, dibenamine, dibozane and ethomoxane were hypotensive while thymoxamine had no effect on blood pressure. Dibozane and dibenamine reduced the hypotensive effect of clonidine.4. In dogs, azapetine, dibozane and ethomoxane reduced blood pressure, while dibenamine induced an increase in blood pressure and thymoxamine was without effect. Only dibenamine antagonized the blood pressure lowering effect of clonidine. A definite conclusion could not be drawn with azapetine due to its long duration of action in both rabbits and dogs.5. These results suggest that the central receptors involved in the hypotensive effect of clonidine differ from many other central receptors and vary according to the animal species. In addition the a-adrenoceptor blocking agents appear not to have a unique site and mechanism of action on central cardiovascular control.

    Description / Table of Contents: Zusammenfassung Es wird über einen zwölfjährigen Jungen berichtet, der an einer akuten basalen Subarachnoidalblutung nach einer tätlichen Auseinandersetzung — von Augenzeugen nur als Rangelei bezeichnet — mit einem Klassenkameraden verstarb. Als Blutungsquelle wird eine Gefäßruptur im System der Vena cerebri magna Galeni und der Vv. cerebri parvae (internae) auf dem Boden einer möglichen mikrodysontogenetischen Vorschädigung der Gefäße diskutiert.
    Notes: Summary Report of the case of a 12-year-old boy who had died due to massive basal subarachnoid hemorrhage after moderate fight with a class mate. Findings at autopsy and by microscopic examination indicated that a lesion in the system of the great vein of Galen and the internal cerebral veins might have been the source of the bleeding. The nature of an underlying pre-existing vascular change favoring a rupture is discussed on the basis of the clinical history and the pathoanatomic findings.

    Notes: Summary This is a case report of a young policeman who collapsed in the course of a football game. He died seven days later due to a massive intraventricular hemorrhage that resulted in internal hematocephalus. The source of the bleeding was obviously a bilateral angioma of the choroid plexus of the lateral ventricles.

    Histochemische Untersuchungen über das Verhalten der sauren Mukopolysaccharide bei Wundheilung der lamellierenden Keratoplastik (1980)

    Description / Table of Contents: Zusammenfassung Es wurden histochemische Untersuchungen über Veränderungen der sauren Mukopolysaccharide bei lamellierenden Keratoplastiken am Kaninchenauge durchgeführt mit der Toluidinblau-Metachromasie an unfixierten Gefrierschnitten in einer aufsteigenden pH-Reihe von 3,8 bis 5,2. Während sich die metachromatische Reaktion im Transplantat bei Autokeratoplastiken nach 14 Tagen und bei Homokeratoplastiken nach 21 Tagen normalisiert hat, kommt es im seitlichen Narbengebiet zwischen Transplantat und Empfängerhornhaut zu einer bleibenden Verminderung der Metachromasie. Im unteren waagerechten Wund- beziehungsweise Narbengebiet zeigen sich während der Wundheilungsvorgänge in einem Zeitraum zwischen 1 Tag und 6 Monaten keine auffälligen Veränderungen der Metachromasie. Bei längerer Verweildauer der Nylonfäden kommt es zu einer dauernden Verminderung der metachromatischen Reaktion im lamellären Transplantat.
    Notes: Abstract Histochemical investigations were carried out in a series of toluidine blue preparations of pH 3.8–5.2 of unfixed frozen corneal sections of lamellar keratoplasties in rabbit eyes to show alterations in the pattern of acid mucopolysaccharides during wound healing. The metachromasia in lamellar auto- and homokeratoplasties is mainly reduced in the region of the vertical hostgraft junction. When using virgin silk the zone of reduced metachromasia in the vertical junction is broader compared with a 9/0-Nylon suture. The metachromasia of the lamellar transplant becomes normal in autokeratoplasties (Table 1) after a fortnight and in homokeratoplasties after 3 weeks; otherwise the metachromasia during the wound healing shows no significant difference in auto- and homokeratoplasties. The normal pattern of mucopolysaccharides in the corneal stroma does not return in the vertical host-graft junction, but this scar becomes smaller over a period of time (Fig. 3, 4, 5). There are no significant alterations of metachromasia found in the horizontal host-graft junction during wound healing between 1 day and 6 months, but starting from the 7th day after the lamellar keratoplasty using PAS-stain a small more PAS-intensive coloured line in the horizontal host-graft junction which is still there 6 months after the operation (Fig. 1, 2). When the 9/0 Nylon suture remains for 3 months, corneal vascularisation develops predominantly in the horizontal junction between host and lamellar graft. The graft becomes cloudy and the metachromasia remains reduced as long as 9 months after the suture has been removed (Table 2).

    Notes: Abstact: The kinetic energy spectrum and the polarization of the PSI neutron beam produced in the reaction 12C(p,n)X at 0° with 590 MeV polarized protons were investigated. A strong energy dependence of the neutron beam polarization is observed which was not expected at the time the neutron beam was built.

The method is based on the use of general analytic properties of the differential cross section in the cosgq-plane.
