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

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.

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

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

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 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

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

Deep space radiation treatment reboots brain’s immune system

21. Mai. 2018

NASA and private company SpaceX plan to send humans to Mars within the next 15 years — but need to figure out how to protect astronauts from the dangerous cosmic radiation of deep space. Now neuroscientists have identified a potential treatment for the brain damage caused by cosmic rays — a drug that prevents memory impairment in mice exposed to simulated space radiation.

Are humans causing cancer in wild animals?

21. Mai. 2018

As humans, we know that some of our activities can cause cancer to develop in our bodies. Smoking, poor diets, pollution, chemicals used as additives in food and personal hygiene products, and even too much sun can contribute to an increased risk of cancer. But, are human activities also causing cancer in wild animals? Researchers think so and are urgently calling for research into this topic. (Mehr in: Cancer News — ScienceDaily)

A way to prevent pancreatic cancer from spreading post-surgery?

17. Mai. 2018

New research suggests a strategy for lowering the odds of metastasis following successful pancreatic cancer surgery: The post-operative period, suggests a researcher, ‚offers a window during which efforts might be made to keep cortisol levels down and T cells strong so the patient’s own immune system can kill the cancer cells that have made their way to other parts of the body but until this point have been dormant.‘ (Mehr in: Cancer News — ScienceDaily)

Immune cell provides cradle for mammary stem cells

17. Mai. 2018

Researchers have made new discoveries about how an immune cell known as the macrophage, which normally fights infection by swallowing foreign invaders, nurtures mammary gland stem cells through a chemical signaling molecule. The study may provide important clues about the roles of macrophages in breast cancer progression. (Mehr in: Cancer News — ScienceDaily)

For women, mammograms are a sometimes uncomfortable, but necessary, annual ritual. But this procedure doesn’t always provide accurate results, and it exposes women to X-rays. In a new study, scientists report that they have developed a non-invasive ‚disease screening pill‘ that can make cancerous tumors light up when exposed to near-infrared light in mice without using radiation.

Cell type switch helps colon cancer evade treatment, study suggests

16. Mai. 2018

Researchers have discovered that colon cancers are often resistant to existing drug treatments because they are composed of two different cell types that can replace each other when one cell type is killed. The study suggests that combination therapies targeting both cell types at once may be more effective at treating colorectal cancer, the third highest cause of cancer-related death in the United States.

Different diseases elicit distinct sets of exhausted T cells

15. Mai. 2018

The battle between the human immune system and long-term, persisting infections and other chronic diseases such as cancer results in a prolonged stalemate. Over time battle-weary T cells become exhausted, giving germs or tumors an edge. Using data from multiple molecular databases, researchers have found nine distinct types of exhausted T cells, which could have implications for fighting chronic infections, autoimmunity, and cancer.

First clues to the causes of multiple sclerosis

15. Mai. 2018

There is still no cure for multiple sclerosis, with current treatments largely based on managing symptoms, especially accelerating recovery phases following a relapse and reducing the number and severity of relapses. Researchers have now identified a DNA-binding factor called TOX that might play a role in triggering multiple sclerosis. They found that TOX license immune cells to cause autoimmune tissue destruction in the brain. (Mehr in: Cancer News — ScienceDaily)

Das Babel-Projekt I – Epistemische Funktionen von Metaphern im wissenschaftlichen Erkenntnisprozess

02. Mai. 2018

Unsere Wahrnehmung der Welt und der wissenschaftliche Zugang zu ihrer kausalen Struktur sind wesentlich mit dem Gebrauch von Sprache – insbesondere Metaphern – verbunden. Metaphern erfüllen epistemische Funktionen, indem sie durch die Anlehnung an einen bekannten Quellbereich eine speziell geartete Vorstellung eines neuen, abstrakteren Konzeptes (Zielbereich) vermitteln. Sie sind somit auch für die Neukonstruktion und Artikulation von Theorien und Begriffen bedeutsam. (Mehr in: Veranstaltungen – idw – Informationsdienst Wissenschaft)
