It seems clear therefore that a student of physiology could best use this book in conjunction with a bigger book that is both more detailed and more current. The advantage of this book is that it is short enough that one can retain perspective. A quite amazingly current bonus that comes with the book is its sophisticated introduction to S. I. metric units of measurement. It foretells and helps ...

The solid-state electrical conductivities of a number of ferredoxin model compounds are reported. For one of these compounds, (KFeS(2))(n), an electron transfer rate for a 25 A unit is shown to be at least 1 x 10(8) electrons sec(-1). The rate becomes proportionally larger for smaller molecular units. This rapid rate is consistant with a short pipe model for electron transport between two react...

There are some discrepancies between the behaviours of the metal-ligand biosystems and the lifeless systems. The participation of macromolecular ligands might be considered as the most important origin of these discrepancies. The amphivalency, flexibility, adaptation to coordination configurations and the availability of the metal-binding sites determine the characteristics of the metal(1igand)...

This Seventeenth Growth Symposium volume is comprised of papers presented in June of 1958. As stated in the foreword, the theme of the conference was that of "Differentiation and growth in response to a changing chemical environment." As Dr. Rudnick points out, and as is all too obvious, this permits an extremely wide range of papers. Subjects and authors are: (1) Wilde-Differentiation in respo...

During the evolution of many systems found in nature, both the system composition and the interactions between components will vary. Equating the dimension with the number of different components, a system which adds or deletes components belongs to a class of dynamical systems with a finite dimensional phase space of variable dimension. We present two models of biochemical systems with a varia...

mobile phone use and wireless communication technology have grown explosively over the past decades. this rapid growth has caused widespread global concern about the potential detrimental effects of this technology on human health. stem cells generate specialized cell types of the tissue in which they reside through normal differentiation pathways. considering the undeniable importance of stem ...

Systems biology is a new field in biology that aims at system-level understanding of biological systems. While molecular biology has led to remarkable progress in our understanding of biological systems, the current focus is mainly on identification of genes and functions of their products which are components of the system. The next major challenge is to understand at the system level biologic...

The design of artificial biological systems and the understanding of their natural counterparts are key objectives of the emerging discipline of synthetic biology. Toward both ends, research in synthetic biology has primarily focused on the construction of simple devices, such as transcription-based oscillators and switches. Construction of such devices should provide us with insight on the des...

We defend the fundamental ontological-pragmatic principle that often where there are continua in reality, science is forced to make partly fiat terminological delimitations. In particular, this principle applies when it comes to describing biological organisms, their parts, properties, and relations. Human-made fiat delimitations are indispensable at the level of both individuals and the natura...
