Over one hundred contributions detail advances in the molecular and cellular biology of eicosanoid production, as well as their role in signal transduction. One of the most exciting developments explored within this collection of articles is the expression of the novel isoform of cyclooxygenase (cox-2), which may play a large role in the development of anti-inflammatory drugs.

Contains the proceedings of a July-August 1994 workshop which brought together 60 leading scientists, including many Nobel Laureates in high energy physics and principal contributors in other fields of physics, and 36 selected up-and-coming physicists. First-hand accounts by the authors of some of t

Dendritic cells are antigen-presenting cells, and are found in all tissues and organs of the body. Papers from the June 1994 symposium are arranged in sections covering dendritic cells origin and differentiation; phenotype; antigen processing and presentation; cell migration; follicular dendritic ce

The optical properties of semiconductors have played an important role since the identification of semiconductors as "small" bandgap materials in the thinies, due both to their fundamental interest as a class of solids baving specific optical propenies and to their many important applications. On the former aspect we can cite the fundamental edge absorption and its assignment to direct or indirect transitions, many-body effects as revealed by exciton formation and photoconductivity. On the latter aspect, large-scale applications sucb as LEDs and lasers, photovoltaic converters,...

Proceedings of a NATO Advanced Study Institute/Twentieth Course of the International School of Biophysics, held in Erice, Italy, Oct.-Nov. 1991. The fourth course on Bioelectrochemistry differed somewhat from the proceeding ones because of greater emphasis on physiological phenomena. The course was

Until recently, the field of atomic and molecular collisions was left to a handful of practitioners who essentially explored it as a branch of atomic physics and gathered their experimental re sults mainly from spectroscopy measurements in bulk. But in the past ten years or so, all of this has dramatically changed, and we are now witnessing the rapid growth of a large body of research that encompasses the simplest atoms as well as the largest mole cules, that looks at a wide variety of phenomena well outside purely spectroscopic observation, and that finds applications in an unexpectedly...

The proceedings of the September 1990 NATO Advanced Research Workshop comprise papers and poster abstracts in four sections: general overview; the molecular basis of patterning (introduction; pattern of pattern; retinoids and other factors); the extracellular matrix and limb development (overview; c

An overview of semimagnetic and diluted magnetic semiconductors, which are interesting because they confer many new physical properties on both bulk materials and on heterostructures, apparently by exchange interactions between magnetic moments and either magnetic ions or the spin of the charge carr

Scientists examine a number of issues in estimating the health effects of burning solid waste, increasingly being considered by American cities as their landfills get full. Designed to be useful to scientists, laypeople, regulators, and regulatees. Among the topics are models of the atmospheric dist

Angiogenesis is the formation of new blood vessels as outgrowths of existing ones; it occurs during ovulation and wound healing, but is also associated with about 50 diseases, such as diabetic retinopathy and arthritis, and precedes neoplastic transformation. Some 30 papers from a workshop in Porto
