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 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 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

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

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 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

Nanohyperthermia softens tumors to improve treatment

The mechanical resistance of tumors and collateral damage of standard treatments often hinder efforts to defeat cancers. However, a team of researchers has successfully softened malignant tumors by heating them. This method, called nanohyperthermia, makes the tumors more vulnerable to therapeutic agents. First, carbon nanotubes (CNTs) are directly injected into the tumors. Then, laser irradiation activates the nanotubes, while the surrounding healthy tissue remains intact.

Antibody for fighting cancer emerges

19. Mai. 2017

While studying the underpinnings of multiple sclerosis, investigators came across important clues for how to treat a very different disease: cancer. Researchers describe an antibody that can precisely target regulatory T cells which in turn unleashes the immune system to kill cancer cells. The team reports that the antibody decreased tumor growth in models of melanoma, glioblastoma and colorectal carcinoma, making it an attractive candidate for cancer immunotherapy.

Antibodies to the proteins PD-1 and PD-L1 have been shown to fight cancer by unleashing the body’s T cells, a type of immune cell. Now, researchers have shown that the therapy also fights cancer in a completely different way, by prompting immune cells called macrophages to engulf and devour cancer cells.

More cancers diagnosed at early stage following increase in health insurance coverage

Cancer is most curable when it’s detected at its earliest stages. An analysis of nearly 273,000 patients showed that between 2013 and 2014 there was a 1% increase in the percentage of breast, lung, and colorectal cancers diagnosed at the earliest, most treatable stage. Following full implementation of the Affordable Care Act (ACA), this study is the first to explore changes in the proportion of cancers – those that can be detected through screening – diagnosed at stage I.
