Mitochondria and the evolutionary roots of cancer

Cancer is a group of almost 200 diseases that involve variety of changes in cell structure, morphology, and physiology. Cancer phenotype is underlying several alterations in cellular dynamics with three most critical features, which includes self-sufficiency in growth signals and insensitivity to in

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

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

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

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

Wholeness and implicate order: “Deep” quantum chemistry and cell consciousness: quantum chemistry controls genes and biochemistry to give cells and higher organism’s consciousness and complex behavior

Bohm used the term ‘holomovement’ which is an unbroken and undivided totality and carries an implicate order which is he totality of an order including both the manifested and non-manifested aspects of the order. Non-local quantum phenomena reside in a subtler level than quantum level that is th

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.

MDC-Forscher entdecken neue Regulationsebene bei wichtigem Protein

Die Proteinkinase A (PKA) ist ein wichtiges Signalenzym, das sich im ganzen Körper findet und an vielen zellulären Prozessen beteiligt ist. Sie galt bislang als umfassend untersucht. Ein Forschungsteam des Max-Delbrück-Centrums für Molekulare Medizin in der Helmholtz-Gemeinschaft (MDC) hat nun eine neue Regulationsebene der PKA entdeckt und diese Ergebnisse in Nature Communications veröffentlicht.

How a poorly explored immune cell may impact cancer immunity and immunotherapy

17. Nov. 2017

The immune cells that are trained to fight off the body’s invaders can become defective. It’s what allows cancer to develop. So most research has targeted these co-called effector T-cells. But a new study takes a step back and considers: What if the problem isn’t with the effector T-cells but starts higher up the cellular chain? (Mehr in: Cancer News — ScienceDaily)

Protein key to cancer cells ability to spread identified

17. Nov. 2017

Scientists have made a discovery that could reduce the spread of cancer by hindering a protein that binds cancer cells together and allows them to invade tissues. The groundbreaking study identified a protein, known as cadherin-22, as a potential factor in cancer metastasis, or spread, and showed that hindering it decreased the adhesion and invasion rate of breast and brain cancer cells by up to 90 percent.

A new study has shown that the majority of people in the United Kingdom do not understand the connection between weight issues and cancer. Obesity is associated with thirteen types of cancer, including those of the breast, kidney, bowel, and womb. However, after surveying 3293 adults, taken as representative of the UK population, researchers found that only a quarter of respondents were aware of the link between obesity and cancer.

12. Jahrestagung der Deutschen Wirbelsäulengesellschaft (DWG)

20. Nov. 2017

Der diesjährige Schwerpunkt des Kongresses liegt auf den Themen Trauma und Tumor in der Wirbelsäulenchirurgie. Wichtige wissenschaftliche Beiträge zu Tumorerkrankungen, degenerativen Erkrankungen, entzündlichen und metabolischen Erkrankungen, Verletzungen und Deformitäten aber auch zu innovativen Techniken erwarten die Besucherinnen und Besucher. Dabei steht ein fächerübergreifender Ansatz im Vordergrund, denn auch auf dem Gebiet der Wirbelsäulenheilkunde gilt es, Bewährtes zu erhalten und gleichzeitig neuen Behandlungsmethoden gegenüber offen zu sein. Dass die Deutsche Wirbelsäulengesellschaft diesen Anspruch ernst nimmt, zeigt auch die Zentren-Zertifizierung, die in diesem Jahr gestartet wurde.

6. Morbi-RSA Symposium

01. Nov. 2017

Eigentlich soll der morbiditätsorientierte Risikostrukturausgleich – kurz: Morbi-RSA – den Finanzausgleich zwischen den gesetzlichen Krankenversicherungen regeln. Fakt ist: Die Kassen haben nach wie vor die Möglichkeit, ärztliche Diagnosen zu beeinflussen, um so höhere Zuwendungen aus dem Gesundheitsfonds zu erreichen. Das geht aus einem Gutachten des Berliner IGES Instituts hervor – und liefert jede Menge Zündstoff für das 6. Morbi-RSA Symposium am 20. November 2017 in Essen.
