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

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

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

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

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

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

Experimental arthritis drug prevents stem cell transplant complication

25. Apr. 2018

An investigational drug in clinical trials for rheumatoid arthritis prevents a common, life-threatening side effect of stem cell transplants, new research shows. Studying mice, the researchers found the drug prevented what’s known as graft-versus-host disease, a debilitating, sometimes lethal condition that develops when transplanted stem cells attack the body’s own organs or tissues.

Scientists unearth vital link between fat, immunity and heat regulation

24. Apr. 2018

Scientists have discovered a key, previously unknown role for a population of cells that live in our fat — these cells regulate our body heat and protect us against cold shock. The discovery opens the door to future treatments in which weight loss (or gain) is the desired goal, as activating the pathway involved may stimulate the body to burn (or not burn) white fat.

The role of ‚extra‘ DNA in cancer evolution and therapy resistance

23. Apr. 2018

Researchers tracked genomic alterations detected in patient samples during tumor cell evolution in culture, in patient-derived xenograft (PDX) mouse models from the cultures, as well as before and after treatment in patients. The team reports that tumor progression was often driven by cancer-promoting genes, known as oncogenes, on extrachromosomal pieces of DNA. (Mehr in: Cancer News — ScienceDaily)

Researchers have made the surprise discovery that the ‚odd one out‘ in a family of proteins known to drive cancer development is instead critical for preventing stomach cancers. The research team showed switching off a certain gene caused spontaneous development of stomach cancers, driven by chronic inflammation. The study also revealed that immunotherapy may prove to be a significant tool for treating stomach cancers that are driven by runaway inflammation, warranting further investigation.

Soil metals linked with cancer mortality

Epidemiologists and geologists have found associations between esophageal cancer and soils where lead is abundant, lung cancer and terrains with increased copper content, brain tumor with areas rich in arsenic, and bladder cancer with high cadmium levels. These statistical links do not indicate that there is a cause-effect relationship between soil type and cancer, but they suggest that the influence of metals from the earth’s surface on the geographical distribution of tumors should be analyzed.
