dc.description.abstract | Introduction: Ultradian biorhythms represent biological rhythms which last between 20 and 90
minutes. They were discovered in 50s of the last century and approved by using several techniques of
quantitative and qualitative analyzes which demonstrated than that ultradian biorhythms were
characteristic only for some segregated cells, and later there was discovered their influence in regulation
and synchronization of adjacent cell population, also their importance in entire organism homeostasis
maintaining. This research aims to evaluate and categorize the most important aspects of this approaches.
Materials and methods: In order to find answers to the proposed questions, a bioinformatic
study is needed, by using PubMed and Link Springer data base which will be analyzed and structured in
the following way.
Discussions and results: it was discovered that u. biorhythms have more than 20 impacts over
cell functions and properties, such as ATP synthesis, nucleic acids synthesis, synthesis of proteins, cell
activity, protein secretion, cell respiration, the amount of cAMP, and also sometimes u. biorhythms may
influence even the weigh and the size of the cell. Ultradian biorhhythms were identified not only at
human, but also at the rest of mammals, crustaceans, molluscs, protozoa, bacteria and other single-celled
organisms.
During the study it was determined that this biorhythms are not anything else than the result of
auto-organization of cell population’s oscillations.
Actually, exists the idea that this biorhythms are synchronized by the gangliosides, this was
confirmed by several experiments in vitro, where in the intercellular space of some cell populations was
introduced gangliosides, and in this way was discovered that they were responsible for different
processes, the most obvious one was the oscillations during proteins’ synthesis.
More recent and more complex studies show us a more adaptable model regarding the
synchronization of different cell populations, in this way the biorhythms control occurs as fallow:
endogenously ( interstitial fluid ) which involves the following reactions: gangliosides, attach to specific
receptors and release Ca2 + depots, calcium activates protein kinase, so the phosphorylation of specific
proteins occurs and thus sets the stage of biorhythms of synthesis; Exogenously ( blood) in the same
way, the only difference is that protein kinase activated by cAMP which is activated by the adenylate
cyclase, the last one (adenylate cyclase) is activated by adrenaline, serotonin, melatonin, etc. In this
context, it was possible to insight and later to confirm by experimental studies that cell proliferation
depends not only on circadian rhythms but also on those ultradian ones, in this way they having an
applicable aspect in regenerations, ontogenesis and oncological diseases. Other practical aspects which
may be named: heart work, the efficiency of catecholamine receptors and their secretion, the entire
system of organs, intercellular communications, cellular function. Another aspect, also very important,
is that the process of aging may be Associated with a imbalance of intercellular synchronization,
therefore, imbalance at the level of different ultradian rhythms. Researched phenomenon has important
application in several clinical aspects: 1 ) In this way it adjusts the functions of the entire body; 2) The
mechanism affects the ability of the body to work well with a determined frequency; 3) The quantitative
difference of some substances at different periods of time, is important in the effectiveness of drugs
introduced in different phases of ultradian cycles; 4 ) The perspective to compensate aging effects by
introducing certain substances in the intercellular space.5) Better understanding of different organ
systems functionality and the possibility of diagnosis according to the case.
Conclusions: Ultradian biorhytms are not just a trend, and due to high-technologies
developement, they may be used during diagnosis and during the treatement and planification of
therapeutic maneuvers as well. It rests to elucidate, argumentate optimal, corect, economical and
affordable methods of personalized determination of these rhythms. | en_US |
