Enzyme Catalysis and Control
Current Topics in Cellular Regulation: Volume 24, Enzyme Catalysis and Control is a compendium of papers that discusses phosphoryl transfer reactions, the role of water on the free energy of hydrolysis of pyrophosphate, and the hormonal actions of vitamin D. Other papers describe the regulation lipid metabolism by a lipid-carrying protein, the GABA, and taurine enzymes in mammalian brain. One paper examines the role of vitamin D in the metabolism of cells, as well as in the whole animal. Upon absorption in the body, the vitamin undergoes various metabolic transformations before interacting with specific receptors, and then inducting the genome in the target tissues to generate biological and...
Taurine 4
Mitochondria from mammalian tissues possess an elaborate system for 2+ 2+ transporting Ca across their inner membrane which consists of Ca import, 2+ via the Ca uniporter, in response to the mitochondrial membrane 2+ + potential ?? and of Ca release by an antiport system in exchange for H + 9,23 or Na (see Fig. l) . Because the uniporter is dependent upon the external 2+ 2+ 2+ 2+ Ca concentration ([Ca ]), mitochondria accumulate Ca until the [Ca ] o o 2+ decreases to the level at which the uniporter activity balances the Ca efflux. 2+ The [Ca ] at which the uniporter and efflux activities are equal is defined o the “setpoint” andcorresponds to values between 0.3-3μM. 2+ Figure 1.

Glutamine and Glutamate Mammals
Based on the joint effort of a great many top scientists, this book covers most aspects of the metabolism and function of glutamine and glutamate in mammals.
Insect Neurochemistry and Neurophysiology · 1989 ·
This volume contains the proceedings of the Third International Conference on Insect Neurochemistry and Neurophysiology (ICINN'89), which was held at the University of Maryland at College Park, Maryland, on July 10-12, 1989. The ICINN meetings were ini tiated in 1983 at a time when insect neurobiology was emerging as a vigorous sector of entomology, requiring a degree of attention and autonomy long before granted to its sister field, vertebrate neurobiol ogy. The distinctly medical aspects of the latter were replaced by potentiali ties for developing new approaches to insect control, and the difference was reflected in the kind of sponsorship that has made the ICINNs possible. It is to the c...
Antioxidants in Health and Disease Volume 2
This book is a printed edition of the Special Issue "Antioxidants in Health and Disease" that was published in Nutrients
Research Methods in Neurochemistry
This fifth volume of Research Methods in Neurochemistry represents a milestone in that it marks almost a decade since the inception of the series. Over these ten years there has been an almost exponential growth in neuro chemistry accompanied by numerous technical developments. This is the justification for our series; inevitably we have only been able to cover a frac tion of the methodological innovations of the last decade, but we have tried as much as possible to create a balance between the different approaches and philosophies in the study of the chemical basis of brain function. Thus our original format of grouping chapters under various headings-for instance, studies in intact tissues...
Amino Acids
Techniques in the neurosciences are evolving rapidly. There are currently very few volumes dedicated to the methodology - ployed by neurosclentlsts, and those that are available often seem either out of date or limited m scope. This series is about the methods most widely used by modern-day neurosclentists and 1s wrltten by their colleagues who are practicing experts. Volume 1 will be useful to all neurosclentists since It concerns those procedures used routinely across the widest range of subdisciplines. Collecting these general techniques together m a single volume strikes us not only as a service, but will no doubt prove of exceptIona utilitarian value as well. Volumes 2 and 3 - scribe al...
Taurine
The underlying philosophy of these two symposia on taurine remains the same as all those that have been held previously: the best way to remain current in the subject matter is to talk directly with the investigators at the forefront of the field. Thus, we brought together some 50 individuals from 11 different countries who have keen interests and active research programs in the many-faceted areas of taurine research. The meetings were held on October 8-10, 1991, in an elegant setting in a resort area at Orange Beach, Alabama, approximately 50 miles outside of Mobile on the Gulf Coast. The meetings were programmed as two separate Symposia held sequentially. The first symposia on October 8 wa...
Trace Amines
This is the third Proceedings book to arise from biennial conferen ces on the Trace Amines. Since our first meeting in 1983 in Edmonton, Canada, progress has been brisk and, as will be seen from the ensuing pages, it is now possible to include major contributions from inverte brate neurobiologists as well as receptorologists. In the opening ses sion we heard about the distribution of the trace amines-now clear ly a misnomer-in insects and the pharmacological, receptor, and syn aptic characteristics of octopamine and tryptamine as well as the pos sibility of monoamines in general being targets for insecticide discov ery. In mammalian brain the distribution and characterization of the tryptami...
Neurobiology of the Trace Amines
Many of the trace amines-more correctly called biogenic amines have been known for decades, but because of their tiny concentra tions (0. 01-100 ng/g) in brain, it was only after the development of sophisticated analytical techniques (such as mass spectrometry) that they could be identified and quantitated in nervous tissue. There are now more than 20 of them and most are related to the catecholamines and 5-hydroxytryptamine both structurally and metabolically. Their pharmacological and physiological properties make them prime candidates for a transmitter or neuromodulator role and many of them elicit profound behavioral syndromes after injection--one of them, phenylethylamine, has even been...
