Human health risks associated with the natural environment and the human activities therein are interconnected, comprise a wide range of spatial scales and are temporally dynamic and changing. It has been recognized that the health of our natural environment and human health are inextricably linked. Our planet is changing in an unprecedented rate and new challenges emerge from climate and environmental change, globalization, urbanization, and lifestyle changes.

3D-Abbildung auf Basis von Millimeterwellensignalen eröffnet neue Perspektiven für Sicherheitstechnologie oder industrielle Messtechnik. Ohne ionisierende Strahlung können hier materialdurchdringend hochgenaue 3D-Bilder erzeugt werden. Auf welchen Grundsätzen basiert diese Bildgebung? Wie wird die Bildgebung digital umgesetzt? Der Seminarvortrag soll Publikum mit nachrichtentechnischem oder mathematischem Vorwissen einen Einstieg in die Methoden der digitalen Bildgebung ermöglichen.

Why did you write The Secret Language of Cells? While studying signaling among brain cells, I became aware that all our cells—immune cells, gut cells, microbes, plant cells, etc. —are also constantly sending back and forth messages to each other in the same ways that neurons do. These conversations among cells outside of the brain […] Quelle: John Lieff, M.D

The Secret Language of Cells describes revolutionary findings about the interaction of the immune system and the brain and provides a new understanding of the relationship between mind and body. The immune system has a huge impact on the brain and mental health. Similarly, the brain strongly influences immune activity throughout the body. These interactions […] Quelle: John Lieff, M.D

  “The Secret Language of Cells … presents a new paradigm for understanding health and disease.” Andrew Weil, MD, director of the Andrew Weil Center for Integrative Medicine, professor at University of Arizona College of Medicine, and author This new paradigm, described in my upcoming book, The Secret Language of Cells, is based on the newly-recognized principle […] Quelle: John Lieff, M.D

It is only recently that scientists have been able to observe tiny viruses and their behavior. Bacteria are a thousand times larger than viruses, and our human cells are a thousand times larger than bacteria. We still don’t know what viruses are and how they can have such a complex lifestyle while consisting of just […] Quelle: John Lieff, M.D

Dear Reader,                      During a several year hiatus from writing new blog posts, I have completed my book, The Secret Language of Cells, which is due to be published this September. It is a synthesis, organization, and update of much of what I have written in my […] Quelle: John Lieff, M.D

The Secret Language of Cells takes us on an exciting journey into a world where we can visualize elaborate conversations among immune cells, brain cells, gut cells, bacteria, and even viruses. Dr. Lieff gives a wealth of examples for his thesis that this cellular signaling is the basis of life. It is a must read for anyone […] Quelle: John Lieff, M.D

Muhammad A Shah, Emily L Denton, Cheryl H Arrowsmith, Mathieu Lupien and Matthieu Schapira Abstract Background The notion that epigenetic mechanisms may be central to cancer initiation and progression is supported by recent next-generation sequencing efforts revealing that genes involved in chromatin-mediated signaling are recurrently mutated in cancer patients. Results Here, we analyze mutational and transcriptional profiles from TCGA and the ICGC across a collection 441 chromatin factors and histones. Chromatin factors essential for rapid replication are frequently overexpressed, and those that maintain genome stability frequently mutated. We identify novel mutation hotspots such as K36M in histone H3.1, and uncover…

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 inhibitory signals, evasion of programmed cell death and limitless replicative potential with a potential for the invasion of other organs. Cancer disease is widespread among metazoans. Some properties of cancer cells such as uncontrolled cell proliferation, lack of apoptosis, hypoxia, fermentative metabolism and free cell motility, i.e. metastasis, resemble a prokaryotic lifestyle, which leads to the assumption of…

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.

Progressive increase in mtDNA 3243A>G heteroplasmy causes abrupt transcriptional reprogramming Wallace hypothesized mitochondrial dysfunction as a central role in a wide range of age-related disorders and various forms of cancer. Steadily rising increases in mitochondrial DNA mutations cause abrupt shifts in diseases. Discrete changes in nuclear gene expression in response to small increases in DNA mutant level are analogous to the phase shifts that is well known in physics: As heat is added, the ice abruptly turns to water or with more heat abruptly to steam. Therefore, a quantitative change that is an increasing proportion of mitochondrial DNA mutation results…

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 tissues is attributable to environmental factors or inherited predispositions. The majority is due to bad luck, that is, random mutations arising during DNA replication in normal, noncancerous stem cells. Tomasetti C, Vogelstein B (2015): Variation in cancer risk among tissues can be explained by the number of stem cell divisions. Science 2 January 2015:…

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 solid. However, living organisms are essentially isothermal. Because of very little differences in temperature between different parts of a cell it is assumed that energy flow in living organisms is mediated by differences in the turnover time of various metabolic processes in the cell, which occur in cyclical fashion. It has been shown that the cycle time of…
