Oscillations in biological systems
Biosystems, 1970Abstract In this paper an attempt is made to illustrate that lower frequency oscillations — in metabolic processes 3$¯seen at intracellular levels and at tissue and entire organism levels are similarly related; i.e., that there is a regularization of the signals from many millions of cells into a few integrated signals in the overall system.

Chaos is a widespread and easily recognizable phenomenon that hardly anybody took notice of until recently. The reason may be that chaos has something profoundly counterintuitive about it. It will not fit easily into any familiar cause–effect frame. The best introduction to chaos is by the way of an example. Consider a leaking faucet (Shaw, 1984). When

Sialidases in biological systems
Die Pharmazie, 2010Sialidases are very common in biological systems. They are found particularly in diverse virus families and bacteria, but also in protozoa, some invertebrates and mammalian. The enzymes differ in their biochemical properties, e.g., kinetics, binding affinity or substrate preference. Nevertheless, they have conserved domains and structural similarities.

Biologics in Systemic Sclerosis
Current Pharmaceutical Biotechnology, 2014Systemic sclerosis (scleroderma) is a heterogeneous autoimmune disorder characterized by collagen overproduction that leads to cutaneous and internal organs sclerosis and pulmonary arterial hypertension. SSc has high morbidity and mortality. SSc pathogenesis is uncertain. At present most therapies of SSc are symptomatic.

Observation and biological systems
Bulletin of Mathematical Biology, 1977A number of apparently different lines of inquiry into fundamental biological processes point to the central role played by the notion of observation in the theory of biological systems. Not only do we use the results of our own observations to obtain the system descriptions which are the starting-points for an understanding of biological processes ...

A logic for biological systems
Biosystems, 2000This paper proposes a specification language, hybrid projection temporal logic of modelling, analyzing and verifying biological systems which can be considered, in general, to be hybrid systems consisting of a non-trivial mixture of discrete and continuous components.

The object of this article is to draw attention to some of the major areas of investigation of the state of water in biochemical and biological systems. Deductions about the role of water in such systems are somewhat speculative, but the situation might be improved.

Personality: A biologic system
Conditional Reflex, 1971The personality of man is a biologic system structured on the individual’s genetic and anatomic-physiologic potentials for species-specific adaptations. The system also projects him into a social and physical environment. His relationship with this environment is as integral to his being as the unity of his organ parts are to the function of his body ...

Gravity effects on biological systems
Advances in Space Research, 1992Theoretical investigations of the membrane-solution interface predict different effects of gravity on vertically and horizontally oriented planar membranes. Single channel events of gramicidin incorporated into phosphatidylserine planar bilayer membranes were measured in 0.1 M KCl solution, pH 7, at room temperature.
