Mazzoccoli G. Chronobiology Meets Quantum Biology: A New Paradigm Overlooking the Horizon? Front Physiol 2022; 13:892582. [PMID: 35874510 PMCID: PMC9296773 DOI: 10.3389/fphys.2022.892582] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/10/2022] [Accepted: 05/27/2022] [Indexed: 11/13/2022] Open
Abstract
Biological processes and physiological functions in living beings are featured by oscillations with a period of about 24 h (circadian) or cycle at the second and third harmonic (ultradian) of the basic frequency, driven by the biological clock. This molecular mechanism, common to all kingdoms of life, comprising animals, plants, fungi, bacteria, and protists, represents an undoubted adaptive advantage allowing anticipation of predictable changes in the environmental niche or of the interior milieu. Biological rhythms are the field of study of Chronobiology. In the last decade, growing evidence hints that molecular platforms holding up non-trivial quantum phenomena, including entanglement, coherence, superposition and tunnelling, bona fide evolved in biosystems. Quantum effects have been mainly implicated in processes related to electromagnetic radiation in the spectrum of visible light and ultraviolet rays, such as photosynthesis, photoreception, magnetoreception, DNA mutation, and not light related such as mitochondrial respiration and enzymatic activity. Quantum effects in biological systems are the field of study of Quantum Biology. Rhythmic changes at the level of gene expression, as well as protein quantity and subcellular distribution, confer temporal features to the molecular platform hosting electrochemical processes and non-trivial quantum phenomena. Precisely, a huge amount of molecules plying scaffold to quantum effects show rhythmic level fluctuations and this biophysical model implies that timescales of biomolecular dynamics could impinge on quantum mechanics biofunctional role. The study of quantum phenomena in biological cycles proposes a profitable “entanglement” between the areas of interest of these seemingly distant scientific disciplines to enlighten functional roles for quantum effects in rhythmic biosystems.

The Double-Aspect of Life. BIOLOGY 2018; 7:biology7020028. [PMID: 29735890 PMCID: PMC6023002 DOI: 10.3390/biology7020028] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/13/2018] [Revised: 05/02/2018] [Accepted: 05/04/2018] [Indexed: 12/13/2022]
Abstract
Life is based on two aspects: matter and a non-material, electrical component. In a dynamic system of reciprocal causality, matter and the so-called bioelectricity interact with one another, forming a functional unity. The aim of this essay is to summarize evidence for bioelectricity, for the sensitivity of biosystems to external physical factors and for the interactions of internal bioelectricity with internal biochemical structures. I propose non-material information of bioelectrical states to be just as inheritable from generation to generation as is the material genetic code.

Abstract
After 30 years of hematopoietic stem cell use for various indications, umbilical cord blood is considered as an established source of cells with marrow and postmobilization peripheral blood. The limited number of cells still remains a problematic element restricting their use, especially in adults who require to be grafted with a higher cell number. Improving the quality of harvested cord blood, at least in terms of volume and amount of cells, is essential to decrease the number of discarded units. In this review, we examine several variables related to parturient, pregnancy, labor, delivery, collection, the newborn, umbilical cord, and placenta. We aim to understand the biologic mechanisms that can impact cord blood quality. This knowledge will ultimately allow targeting donors, which could provide a rich graft and improve the efficiency of the collection.

Endogenous physical regulation of population density in the freshwater protozoan Paramecium caudatum. Sci Rep 2017; 7:13800. [PMID: 29062014 PMCID: PMC5653844 DOI: 10.1038/s41598-017-14231-0] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/04/2017] [Accepted: 10/06/2017] [Indexed: 01/08/2023] Open
Abstract
Studies confirm physical long-range cell-cell communication, most evidently based on electromagnetic fields. Effects concern induction or inhibition of cell growth. Their natural function is unclear. With the protozoan Paramecium caudatum I tested whether the signals regulate cell density and are electromagnetic. Up to 300 cells/mL, cell growth in clones of this study is decreasingly pronounced. Using cuvettes as chemical barriers enabling physical communication I placed 5 indicator cells/mL, the inducer populations, into smaller cuvettes that stand in bigger and contained 50, 100, 200 or 300 cells/mL. Under conditions of total darkness such pairs were mutually exposed for 48 hours. The hypothesis was that indicator cells, too, grow less the more neighbor cells there are. The bigger inducer populations were in the beginning the less they grew. The indicator populations grew accordingly; the more cells they were surrounded by the less they grew. The suppressing neighbors-effect disappeared when inner cuvettes were shielded by graphite known to shield electromagnetic radiation from GHz to PHz, i.e. to absorb energy from microwaves to light. These are the first results demonstrating non-contact physical quorum sensing for cell population density regulation. I assume rules intrinsic to electromagnetic fields interacting with matter and life.

Abstract
The molecular clockwork drives rhythmic oscillations of signaling pathways managing intermediate metabolism; the circadian timing system synchronizes behavioral cycles and anabolic/catabolic processes with environmental cues, mainly represented by light/darkness alternation. Metabolic pathways, bile acid synthesis, and autophagic and immune/inflammatory processes are driven by the biological clock. Proper timing of hormone secretion, metabolism, bile acid turnover, autophagy, and inflammation with behavioral cycles is necessary to avoid dysmetabolism. Disruption of the biological clock and mistiming of body rhythmicity with respect to environmental cues provoke loss of internal synchronization and metabolic derangements, causing liver steatosis, obesity, metabolic syndrome, and diabetes mellitus.
