Target Organ Toxicology in Caenorhabditis elegans

by Dayong Wang

This book introduces readers to intestinal and epidermal barriers, and to toxicity induction of environmental toxicants or stresses in the intestine, epidermis, neurons, muscle, and reproductive organs in Caenorhabditis elegans. In addition, it discusses the protective responses of various organs and nematodes’ avoidance behaviour with regard to environmental toxicants or stresses. The intestinal, epidermal, neuronal, and germline signalling pathways required for the regulation of toxicity of environmental toxicants or stresses are also introduced and discussed. As a classic model animal with well-described genetic and developmental backgrounds, the nematode Caenorhabditis elegans has been successfully and widely used in both toxicity assessments and toxicological studies on various environmental toxicants and stresses. Once exposure to certain environmental toxicants has occurred, the toxicants can enter into the primary targeted organs (such as intestinal cells), and even be translocated into secondary targeted organs (such as reproductive organs and neurons). Based on related available data, this book provides a systematic understanding of target organ toxicology in C. elegans.

Virus Infection and Tumorigenesis: Hints from Marine Hosts’ Stress Responses

by Xiaobo Zhang

This book reviews the latest research on the molecules and mechanisms of marine host stress responses to viral infections and tumorigenesis. It offers an overview of the state of the art in the field as well as future directions. Metabolism disorder is a characteristic of tumorigenesis. Since viruses complete their life cycle in host cells, such infections cause metabolic disorders in the host. As such, the mechanisms of virus pathogenesis and tumor progression are similar or even identical. In essence, the role of antiviral molecules is to maintain the metabolic homeostasis of infected host cells, and the antiviral molecules induced by virus infection may play an important role in antitumor pathways, resulting in cancer cell death or restoring the disordered metabolism of cancer cells. The molecules generated during host stress responses to viruses can also contribute to the antitumor mechanisms in humans. However, the relationship between host stress responses to virus infection and tumorigenesis has not been extensively explored. In recent years, studies have shown that marine host stress responses to viral invasion can be good models for exploring human antitumor mechanisms. Stimulating further research in the field, this book offers graduate students and researchers with comprehensive insights into host stress responses to viral invasion and tumor progression. It is also a valuable resource for those working in the pharmaceutical industry interested in drug discovery based on molecules derived from host stress responses to viral infection.

Bonobo and Chimpanzee: The Lessons of Social Coexistence (Primatology Monographs)

by Takeshi Furuichi

This book describes the similarities and differences between two species, bonobos and chimpanzees, based on the three decades the author has spent studying them in the wild, and shows how the contrasting nature of these two species is also reflected in human nature. The most important differences between bonobos and chimpanzees, our closest relatives, are the social mechanisms of coexistence in group life. Chimpanzees are known as a fairly despotic species in which the males exclusively dominate over the females, and maintain a rigid hierarchy. Chimpanzees have developed social intelligence to survive severe competition among males: by upholding the hierarchy of dominance, they can usually preserve peaceful relations among group members. In contrast, female bonobos have the same or even a higher social status than males. By evolving pseudo-estrus during their non-reproductive period, females have succeeded in moderating inter-male sexual competition, and in initiating mate selection. Although they are non-related in male-philopatric society, they usually aggregate in a group, enjoy priority access to food, determine which male is the alpha male, and generally maintain much more peaceful social relations compared to chimpanzees. Lastly, by identifying key mechanisms of social coexistence in these two species, the author also seeks to find solutions or “hope” for the peaceful coexistence of human beings."Takeshi Furuichi is one of very few scientists in the world familiar with both chimpanzees and bonobos. In lively prose, reflecting personal experience with apes in the rain forest, he compares our two closest relatives and explains the striking differences between the male- dominated and territorial chimpanzees and the female-centered gentle bonobos."Frans de Waal, author of Mama’s Last Hug - Animal Emotions and What They Tell Us about Ourselves (Norton, 2019)

Low-Dose Radiation Effects on Animals and Ecosystems: Long-Term Study on the Fukushima Nuclear Accident

by Manabu Fukumoto

This open access book summarizes the latest scientific findings regarding the biological effects of the Fukushima Daiichi Nuclear Power Plant (FNPP) accident in 2011.Various cases of changes in animals and organisms have been reported since the FNPP accident. However, it is often unknown whether they are actually due to radiation, since the dose or dose-rate are not necessarily associated with the changes observed. This book brings together the works of radiation biologists and ecologists to provide reliable radioecology data and gives insight into future radioprotection.The book examines the environmental pollution and radiation exposure, and contains valuable data from abandoned livestock in the ex-evacuation zone and from wild animals including invertebrates and vertebrates, aqueous and terrestrial animals, and plants that are subjected to long-term exposure in the area still affected by radiation. It also analyzes dose evaluation, and offers new perspectives gained from the accident, as well as an overview for future studies to promote radioprotection of humans and the ecosystem.Since the biological impact of radiation is influenced by various factors, it is difficult to scientifically define the effects of low-dose/low-dose-rate radiation. However, the detailed research data presented can be combined with the latest scientific and technological advances, such as artificial intelligence, to provide new insights in the future.This book is a unique and valuable resource for researchers, professionals and anyone interested in the impact of exposure to radiation or contamination with radioactive materials.

The Alpheidae from China Seas: Crustacea: Decapoda: Caridea

by Zhong-li Sha Yan-rong Wang Dong-ling Cui

As one of the largest families within the Caridea, the Alpheidae have attracted much attention for its species richness, especially on coral reefs. The Alpheidae are one of the most abundant decapods in tropical and subtropical areas, with 48 genera and more than 700 known species. The Alpheidae present a particular challenge in terms of both taxonomy and systematics as they are difficult to identify (some species vary in their growth and there are often large differences between the sexes). Traditional, morphology-based research on the Alpheidae still plays an important role in identifying species, compared with new methods, such as the short gene sequences. Based on more than 2000 specimens collected from the China Seas, this book describes and clearly illustrates 146 species belonging to 16 genera of the Alpheidae. It also presents the key features of every genus and every species within every genus, to enable readers to easily identify the alphid shrimps of the China Seas.
