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

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 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

Weltschlaganfalltag: Hirninfarkt bei jungen Menschen

Berlin – Laut der aktuellen Gesundheitsberichterstattung des Bundes haben hierzulande rund 1,76 Millionen Erwachsene mindestens einmal in ihrem Leben einen Schlaganfall erlitten . In der Akutversorgung nimmt die Bundesrepublik europaweit eine Vorreiterrolle ein – Strukturen für eine gute Nachsorge bestehen bisher jedoch kaum. Anlässlich des Weltschlaganfalltags am 29. Oktober diskutieren Experten der Deutschen Schlaganfall-Gesellschaft (DSG) deshalb auf einer Pressekonferenz, wie eine hochwertige Nachsorge gestaltet werden sollte. Zudem informieren sie über den Schlaganfall bei jungen Menschen und über wirksame Therapiemöglichkeiten. Die Pressekonferenz findet am 25.10.17 in Berlin statt.

Molecular Trojan horse delivers chemotherapeutic drug to cancer cells

23. Feb. 2018

Researchers have discovered a way for chemotherapy drug paclitaxel to target migrating, or circulating, cancer cells, which are responsible for the development of tumor metastases. Until now, paclitaxel has only been used to target rapidly dividing cancer cells. The team was successful in getting the drug to piggyback on 123B9, an agent they devised to target an oncogene called EphA2. (Mehr in: Cancer News — ScienceDaily)

Scientists find molecular link between Vitamin A derivative and mouse intestinal health

22. Feb. 2018

New research shows that all-trans-retinoic acid (atRA), the active form of vitamin A, regulates immune system responses in the mouse intestine by controlling expression of the protein HIC1 in cells known as innate lymphoid cells. These findings could suggest new ways to fight disease. (Mehr in: Cancer News — ScienceDaily)

Cancer risk associated with key epigenetic changes occurring through normal aging process

22. Feb. 2018

Some scientists have hypothesized that tumor-promoting changes in cells during cancer development — particularly an epigenetic change involving DNA methylation — arise from rogue cells escaping a natural cell deterioration process called senescence. Now, researchers have demonstrated that instead, tumor-associated epigenetic states evolve erratically during early stages of tumor development, eventually selecting for a subset of genes that undergo the most changes during normal aging and in early tumor development.

Nitrate in drinking water increases the risk of colorectal cancer, study finds

Nitrate in groundwater and drinking water, which primarily comes from fertilisers used in the agricultural production, has not only been subject to decades of environmental awareness — it has also been suspected of increasing the risk of cancer. The largest epidemiological study ever carried out in this area now shows that there is a correlation — also when the amount of nitrate in the drinking water is far below the current drinking water standard.
