Octopamine in invertebrates

Progress in Neurobiology, 1999
Octopamine (OA), a biogenic monoamine structurally related to noradrenaline, acts as a neurohormone, a neuromodulator and a neurotransmitter in invertebrates. It is present in relatively high concentrations in neuronal as well as in non-neuronal tissues of most invertebrate species studied. It functions as a model for the study of modulation in general.

Invertebrates in neurotoxicology [PDF]

open access: possibleActa Biologica Hungarica, 2000
Due to the relative simplicity of their nervous system, invertebrate animals were widely used in the past decades for studying the processes of excitability at membrane level, as well as the mechanisms of neuronal events and interneuronal communication. Parallel with investigating basic questions of neurobiology, lower animals have also been the object

Is there “pain” in Invertebrates?

Behavioural Processes, 1986
In contrast to nociception, the perception of pain, or pain experience, remains a subjective notion applicable to humans, but untestable with animals. Yet, when defined operationally as a physiological response induced in an animal by stimuli painful to humans, and resulting in a protective stimulus avoidance response, pain is amenable to testing with ...

Oncology of invertebrates

Veterinary Clinics of North America: Exotic Animal Practice, 2004
In this article, "Invertebrates" are considered to be all those animals that are not in the five main groups of vertebrates (Mammalia,Aves, Reptilia, Amphibia, and three classes of fish), and the term neoplasm is used in its traditional sense of "new, uncontrolled, growth".

Viruses of Invertebrates

1968
Publisher Summary The chapter discusses the viruses of invertebrates. The great majority of the viroses described among the invertebrates occur in the Insecta. In the Lepidoptera, newly found nuclear polyhedroses, intestinal cytoplasmic polyhedroses, and granuloses have been added to the list of inclusion body viroses.

Geriatric Invertebrates

Veterinary Clinics of North America: Exotic Animal Practice, 2020
Invertebrates are becoming more popular and, as collections age, clients may seek veterinary intervention where the welfare of the animal must be considered. This article covers aging in many invertebrate species but with a focus on species likely to be seen in general practice.

Invertebrate lamins

Experimental Cell Research, 2007
Lamins are the main component of the nuclear lamina and considered to be the ancestors of all intermediate filament proteins. They are localized mainly at the nuclear periphery where they form protein complexes with integral proteins of the nuclear inner membrane, transcriptional regulators, histones and chromatin modifiers.

GnRH in the invertebrates: an overview

2002
Publisher Summary This chapter provides an overview of GnRH in the invertebrates. The gonadotropin-releasing hormone (GnRH), which was previously called luteinizing hormone-releasing hormone (LHRH), represents a pivotal peptide in animal reproduction.

Invertebrate care

Veterinary Clinics of North America: Exotic Animal Practice, 2004
Invertebrates are attracting increasing interest within the veterinary profession. They are also significant in their own right; as the Council of Europe's "Charter on Invertebrates" points out, they are the most important component of wild fauna as well as providing food, contributing to agriculture and forestry, and aiding medicine,industry, and ...
