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

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

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

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

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

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

Study prompts new ideas on cancers’ origins

16. Dez. 2017

Cancer therapies often target cells that grow and divide rapidly, such as stem cells, but in studying how stomach cancers occur, researchers found that even when the stomach isn’t able to make stem cells, other cells in the stomach can begin to divide and contribute to precancerous lesions.

What does hair loss have to teach us about cancer metastasis?

15. Dez. 2017

Researchers have identified a signaling pathway regulating cell migration and metastasis. Unexpected hair loss in a preclinical model helped them to identify the pathway. When cells within the skin that maintain hair follicles migrate too often, hair follicle maintenance is disrupted. Researchers speculated that this pathway might also play a role in cancer cell migration. Indeed, they showed that disrupting this pathway in preclinical models increased metastasis.

Bioengineers imagine the future of vaccines and immunotherapy

14. Dez. 2017

In the not-too-distant future, nanoparticles delivered to a cancer patient’s immune cells might teach the cells to destroy tumors. A flu vaccine might look and feel like applying a small, round bandage to your skin. These are examples of how innovative biomaterials could enhance vaccines against HIV and other infectious diseases and immunotherapies for patients with cancer or dampen responses in autoimmune disorders, allergies and transplanted organ recipients.

Liquid biopsy results differed substantially between 2 providers

14. Dez. 2017

Two prostate cancer researchers found significant disparities when they submitted identical patient samples to two different commercial liquid biopsy providers. Liquid biopsy is a new and noninvasive alternative to tumor tissue sequencing, and it is intended to specifically detect and sequence tumor DNA circulating in patients‘ blood. The results are used to help guide doctors to tailor the best treatment for patients at each point of their disease. (Mehr in: Cancer News — ScienceDaily)

Deadly heart rhythm halted by noninvasive radiation therapy

14. Dez. 2017

Radiation therapy often is used to treat cancer patients. Now, doctors have shown that radiation therapy — aimed directly at the heart — can be used to treat patients with a life-threatening heart rhythm. They treated five patients with irregular heart rhythms, called ventricular tachycardia, who had not responded to standard treatments. The therapy resulted in a dramatic reduction in the number of ventricular tachycardia episodes. (Mehr in: Cancer News — ScienceDaily)

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.
