Chemesthesis is the chemical stimulation of receptors on somatosensory neurons usually by noxious chemicals leading to irritation. Transient receptor potential channels play a major role in detecting chemesthetic stimuli and are found in a wide variety of organisms, from yeast to humans. Currently, there are no reports of TRP channels in earthworms. Earthworms, including Lumbricus terrestris, aerate and enrich soil providing a suitable habitat for plants. Hence, chemicals in the soil which repel earthworms could have deleterious effects on plant growth. Allyl isothiocyanate, a prototypical TRPA1 agonist, has been used as an expellant for sampling earthworms, suggesting that earthworms possess TRPA1 channels. We began the search for TRPA1-like channels in earthworms using electrophysiological, immunohistochemical, behavioral and cell dissociation/calcium imaging techniques. We obtained responses from segmental nerves to tactile stimulus, 50mM AITC and pH 3.8, 4.0 and 4.2. Some cells in the epidermis displayed positive immunoreactivity for Drosophila and human TRPA1 homologs. L. terrestris detected and avoided ATIC and cinnamaldehyde (another TRPAI agonist) but not capsaicin (a TRPV1 agonist) in air and soil T-maze behavioral assays. We were able to dissociate cells from L. terrestris epithelium and ventral nerve cord, but could not use them in calcium-imaging experiments.

The Physiology of Earthworms focuses on the three species of earthworms — Liimbricus terrestris, Eisenta foetida, and Allolobophora longa. Other earthworms or oligochaetes such as the fresh-water species are briefly mentioned. The topics covered include the biochemical architecture; digestion and metabolism; calciferous glands; axial field; nitrogenous excretion; water relations; respiration; physiology of regeneration; neurosecretion; nervous system; and behavior of oligochaetes. This book is a good source of information for biology students and researchers conducting work on earthworms and its different species.

Chemesthesis are the chemically initiated sensations that occur via the touch system. Examples in the mouth include the burn of capsaicinoids in chilies, the cooling of menthol in peppermint, and the tingle of carbonation. It is physiologically distinct from taste and smell, but is increasingly understood to be just as important as these senses for their contribution to flavor, especially with the sustained growth in interest in spicy foods from around the world. Chemesthesis: Chemical Touch in Food and Eating surveys the modern body of work on chemesthesis, with a variety of contributors who are well known for their expertise on the topic. After a forward by John Prescott and an introduction by Barry Green (who originally coined the term chemesthesis 25 years ago), the book moves on to survey chemesthetic spices and address the psychology and physiology of chemesthesis; practical sensory and instrumental analysis; the interaction of chemesthesis with other chemical senses; health ramifications; and the application of chemesthesis in food. The major types of chemesthesis, including pungency/burning, cooling, tingling, nasal irritation, and numbing, are each covered in their own chapter. The book concludes with a look to the future. This is the first comprehensive book on chemesthesis since 1990, when Barry Green and his colleagues edited a volume on the perception of chemical irritants, including those in food. This new book is intended to be a vital resource for anyone interested in the sensory impact of the food we eat, including food scientists, sensory professionals, analytical chemists, physiologists, culinary scientists, and others.

In recent decades, there has been a new surge of interest in the history and legacies of the Silk Roads both within academic and public discourses. A field of Silk Roads Studies has come into its own. Consciously mirroring the temperament of its subject, the field has moved out of the narrow niches of particular disciplines to become a truly interdisciplinary endeavor. New research findings about the historical operations of the Silk Roads and interpretations of their legacies for the modern and contemporary world have broken down geographical and temporal divides that once demarcated the Silk Roads as primarily pre-modern and Old World-centered conduits of globalization. In light of these developments, the time is ripe to begin formulating a new definition of the contour of Silk Roads Studies and laying a new foundation for further work in this field. Silk Roads: From Local Realities to Global Narratives brings together leading scholars in multiple disciplines related to Silk Roads studies. It highlights the multiplicity of networks that constituted the Silk Roads, including land and maritime routes, and approaches the Silk Roads from Antiquity to China’s One Belt One Road Initiative from Afro-Eurasia to the Americas. This holistic approach to understanding ancient globalization, exchanges, transformations, and movements - and their continued relevance to the present - is in line with contemporary academic trends toward interdisciplinarity. Indeed, the Silk Roads is such an expansive topic that many approaches to its study must be included to represent accurately its many facets. The volume emphasizes exchange and transformation along the Silk Roads - moments of acculturation or hybridization that contributed to novel syncretic forms. It highlights the multiplicity of networks that constituted the Silk Roads, including land and maritime routes, and approaches to the Silk Roads from Antiquity to China’s One Belt One Road Initiative from Afro-Eurasia to the Americas.

The “bioelectronic nose”, the device which has a similar function to the human smell sensing system, can be realized by combining the olfactory cells or receptors with nanotechnology. In the last two decades, much has been learned about the smell sensing mechanism in biological systems. With knowledge about the biological olfactory system and the techniques for the expression of biological receptor proteins, we are able to utilize biological materials and systems to mimic the biological olfactory system. In addition to the advances in biological and biotechnological area, nanotechnology has progressed to a great degree. The bioelectronic nose is a good example of the integration of biotechnology and nanotechnology. This book describes basic biological sciences of the olfactory system, biotechnology for the production of olfactory biological elements, and nanotechnology for the development of various sensing devices. The purpose of this book is to provide the reader with a concept, basic sciences, fundamental technologies, applications, and perspectives of the bioelectronic nose.
