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

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

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

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

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.

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

Researchers discover key to drug resistance in common breast cancer treatment

Three-quarters of all breast cancer tumors are driven by the hormone estrogen. These tumors are frequently treated with drugs to suppress estrogen receptor activity, but unfortunately, at least half of patients do not respond to these treatments, leaving them with drug-resistant tumors and few options. Now, scientists have found that two immune system molecules may be key to the development of drug resistance in estrogen-driven breast cancers. (Mehr in: Cancer News — ScienceDaily)

Towards personalised medicine: One type of data is not enough

20. Jun. 2018

To understand the biology of diseased organs researchers can use different types of molecular data. One of the biggest computational challenges at the moment is integrating these multiple data types. A new computational method jointly analyses different types of molecular data and disentangles the sources of disease variability to guide personalised treatment.

New therapeutic opportunity for the treatment of resistant malignant melanoma

20. Jun. 2018

Researchers have revealed that malignant melanoma can reprogram their protein synthesis machinery and become addicted to a new family of enzymes that modify transfer RNAs during acquired resistance. The inhibition of these molecules synergies with targeted therapies to produce a strong anti-tumoral effect. These new findings will be key in the development of improved diagnostic tools and melanoma treatment. (Mehr in: Cancer News — ScienceDaily)

Rare in-vivo study shows weak brain nodes have strong influence on memory network

20. Jun. 2018

The majority of existing simulation studies show that the parts of the brain with high connectivity, the so-called ‚hubs‘, are most important when it comes to several different cognitive tasks. But the results of a rare in-vivo study demonstrates that the nucleus accumbens (NAc) — a part of the brain with weak connections — plays an unexpectedly influential role in enhancing the memory network.

Laser-sonic scanner aims to replace mammograms for finding breast cancer

18. Jun. 2018

For women over 40, mammography is a necessary yet annoying procedure to endure every year or two. The technique, while valuable for reducing breast cancer deaths, is less than ideal because it exposes patients to X-ray radiation and requires their breasts to be painfully squished between plates. The plates flatten the breast so the X-rays can more easily pass through it and produce a clear image. (Mehr in: Cancer News — ScienceDaily)
