Quantum Tunnelling to the Origin and Evolution of Life

Quantum tunnelling is a phenomenon which becomes relevant at the nanoscale and below. It is a paradox from the classical point of view as it enables elementary particles and atoms to permeate an energetic barrier without the need for sufficient energy to overcome it. Tunnelling is being of vital imp

Implications of quantum metabolism and natural selection for the origin of cancer cells and tumor progression

Energy transfer in material solids is driven primarily by differences in intensive thermodynamic quantities such as pressure and temperature. The crucial observation  in quantum-theoretical models was the consideration of the heat capacity as associated with the vibrations of atoms in a crystalline

Variation in cancer risk among tissues can be explained by the number of stem cell divisions

Tomasetti and Vogelstein show that the lifetime risk of cancers of many different types is strongly correlated with the total number of divisions of the normal self-renewing cells maintaining that tissue’s homeostasis. These results suggest that only a third of the variation in cancer risk among t

A new theory of the origin of cancer: quantum coherent entanglement, centrioles, mitosis, and differentiation

Low non-specific, low intensity laser illumination (635, 670 or 830 nm) apparently enhances centriole replication and promotes cell division, what is the opposite of a desired cancer therapy. In the contrary, centrioles are sensitive to coherent light. Then higher intensity laser illumination - stil

Quantum Teleportation and Von Neumann Entropy

From the aspect of the quantum information theories, various quantum entropies are possibly computed at each stage, which ensures the emergence of the entangled states in the intermediate step. If a single qubit quantum teleportation is near the computational basis, the quantum measurement is domina

About metabolism of a carcinoma cell

Most cancer cells utilize aerobic glycolysis irrespective of their tissue of origin. The alteration from oxidative phosphorylation to glycolysis – called the Warburg effect – is an universal phenomen and has now become a diagnostic tool for cancer detection. Warburg O, Posener K, Negelein E.

Quantum entanglement between the electron clouds of nucleic acids in DNA

Rieper, Anders and Vedral modelled the electron clouds of nucleic acids in a single strand of DNA as a chain of coupled quantum harmonic oscillators with dipole-dipole interaction between nearest neighbours. As a main result, the entanglement contained in the chain coincides with the binding energy

Lärm kann Herz-Kreislauf-Erkrankungen und Diabetes begünstigen

Verkehrslärm erhöht das Risiko für Herz-Kreislauf-Erkrankungen und Diabetes. Dies zeigen erste Resultate der SiRENE-Studie unter der Leitung des Schweizerischen Tropen- und Public Health-Instituts (Swiss TPH), die heute im Rahmen des ICBEN-Kongresses (International Commission on Biological Effects of Noise) in Zürich vorgestellt werden.

Infektionen im Babyalter erhöhen das Risiko für Gluten-Unverträglichkeit

Infektionen im frühen Kindesalter fördern das Risiko für eine spätere Zöliakie (Gluten-Unverträglichkeit). Diesen Schluss ziehen Wissenschaftler des Instituts für Diabetesforschung am Helmholtz Zentrum München, Partner im Deutschen Zentrum für Diabetesforschung (DZD). Sie hatten für die aktuelle Ausgabe des ‚American Journal of Epidemiology‘ Daten der Kassenärztlichen Vereinigung Bayerns ausgewertet. Wiederholte Magen-Darm-Erkrankungen im ersten Lebensjahr erhöhen das Risiko demnach besonders. (Mehr in: Pressemitteilungen – idw – Informationsdienst Wissenschaft)

How Insulin in the Brain May Suppress the Subjective Feeling of Hunger

Insulin in the brain may help regulate the hunger sensation and improve functional connectivity in certain cognitive brain regions (default-mode network, DMN *) as well as in the hippocampus and hypothalamus. This is the finding of a new study by researchers at the German Center for Diabetes Research (DZD) in Tübingen. (Mehr in: Pressemitteilungen – idw – Informationsdienst Wissenschaft)

Entzündungsherd Fettgewebe – Neuropeptid-Hormon hemmt Entzündungsreaktion von Makrophagen

Bei starkem Übergewicht oder Fettleibigkeit kommt es im Körper zu gewebeschädigenden Entzündungsreaktionen. Ausgelöst werden diese häufig durch die Gefahrensignale von `überforderten´ Makrophagen im Fettgewebe. Auf Dauer schädigen diese Entzündungsprozesse diverse Körpergewebe, und stehen sogar im Verdacht, bei Adipositas Folgeerkrankungen wie Diabetes Typ 2 oder Atherosklerose auszulösen. Wissenschaftler der Universität Ulm haben nun herausgefunden, dass ein bestimmtes Hormon (Neuropeptid FF) Fettgewebs-Makrophagen davon abhalten kann, solche gewebeschädigenden Entzündungen hervorzurufen.

Neuer therapeutischer Angriffspunkt: Forscher finden „Aus“-Schalter für mTor-Komplex

Die sog. mTor-Kinase ist eine molekulare Schaltzentrale in der Zelle, die den Stoffwechsel, Zellteilung und Zellwachstum reguliert. Bei krankhaften Veränderungen ist eine normale Regulation jedoch nicht mehr gegeben und es wäre hilfreich, wenn man die Zentrale einfach abschalten könnte, etwa um Insulinresistenzen oder das Krebswachstum zu unterbinden. Forscher am FMP haben einen entscheidenden „off“-Schalter gefunden.Paradoxerweise handelt es sich dabei um eine Lipid-Kinase, deren Produkt bislang eher für das Aktivieren von mTor bekannt war.Die Ergebnisse (Fachmagazin Science) lassen auf neue Therapien gegen Diabetes, Fettleibigkeit, Krebs und eine seltene angeborene Muskelkrankheit hoffen.
