Lymphome B mandibulaire isolé révélé par une anesthésie du nerf alvéolaire inférieur
2009
Resume Introduction Les lymphomes mandibulaires sont rares. Ils se manifestent le plus souvent par une tumefaction indolore. Nous rapportons un cas de lymphome mandibulaire revele par une atteinte isolee du nerf alveolaire inferieur evoluant depuis huit mois. Observation Un homme, de 41 ans, etait suivi pour des douleurs hemimandibulaires gauches. Un signe de Vincent s’est progressivement installe, sans anomalie radiologique. Apres huit mois est apparue une tumefaction dure du vestibule inferieur gauche en regard de la 34. La biopsie a etabli le diagnostic de lymphome B. L’affection etait exclusivement mandibulaire. Apres une polychimiotherapie, le patient est en remission complete depuis d…
Bestimmung von Glykolyse-Metaboliten in isolierten Zellkernen
1958
Isolated rat liver nuclei have been analyzed for the intranuclear concentration of 8 glycolytic metabolites, and in addition for the 3 adenine nucleotides, and for malate. All these substrates are to be found in nuclei in a range of concentration comparable to that in the whole tissue. The consequences of these findings with respect to the definite establishment of glycolysis in isolated nuclei, as well as for the intranuclear formation of energy-rich phosphate bonds, are discussed.
Über das Vorkommen von Desoxyribonuclease und Kathepsin in Zellkernen aus Nieren
1950
The authors prepare cell nuclei by a newly developed procedure. Isolated cell nuclei from hog and calf kidney contain almost the whole activity of desoxyribonuclease (depolymerase) of these tissues. — The catheptic activity of isolated cell nuclei from hog kidney is a very considerable one. The importance of these findings is briefly discussed.
Phosphoribomutase- und 5-Phosphoriboisomerase-Aktivität in isolierten Zellkernen
1958
The existence of phosphoribomutase and 5-phosphoriboisomerase has been demonstrated in isolated cellular nuclei from rat liver and swine kidney. Phosphoribomutase has been shown to require Mg-ions for optimal activity.
Spin Switching in Molecular Quantum Cellular Automata Based on Mixed-Valence Tetrameric Units
2016
In this article we focus on the study of spin effects in a single square-planar mixed-valence cell comprising two electrons and in coupled molecular cells for quantum cellular automata. Using the vibronic model we demonstrate that the polarizabilities of the cell are different in spin-singlet and spin-triplet states of the electronic pair. Based on this inference the concept of spin switching in molecular quantum cellular automata is proposed, and the conditions under which this effect is feasible are derived. In order to reveal these conditions we have performed a series of quantum-mechanical calculations of the vibronic energy levels of the isolated cell and of the cell subjected to the e…
