An Examination Of Chimpanzee Use In Human Cancer Research, Jarrod Bailey

Laboratory Experiments Collection

Advocates of chimpanzee research claim the genetic similarity of humans and chimpanzees make them an indispensable research tool to combat human diseases. Given that cancer is a leading cause of human death worldwide, one might expect that if chimpanzees were needed for, or were productive in, cancer research, then they would have been widely used. This comprehensive literature analysis reveals that chimpanzees have scarcely been used in any form of cancer research, and that chimpanzee tumours are extremely rare and biologically different from human cancers. Often, chimpanzee citations described peripheral use of chimpanzee cells and genetic material in predominantly human …

Automatic Recognition Of Frog Calls Using A Multi-Stage Average Spectrum, Wen-Ping Chen, Song-Shyong Chen, Chun-Cheng Lin, Ya-Zhung Chen, Wen-Chih Lin

Bioacoustics Collection

The automatic recognition of animal sounds is one of the powerful techniques for replacing the traditional ecological survey method that mainly depends on manpower, which is hence both costly and time consuming. This study developed an automatic frog call recognition system based on the combination of a pre-classification method of the syllable lengths and a multi-stage average spectrum (MSAS) method. In this system, the input frog syllables are first classified into one of the four groups determined by the pre-classification method according to syllable length. Then the proposed MSAS method is used to extract the standard feature template to analyze …

Veterinary Ethics And Production Diseases, Bernard E. Rollin

Professional Veterinary Ethics Collection

An animal's welfare should be governed by five freedoms, namely, freedom from hunger and thirst, freedom from discomfort, freedom from pain, injury or disease, freedom to express normal behavior and freedom from fear and distress. If the essence of veterinary medicine is to act like a physician for animals then the profession must be vocal in opposition to production diseases, which can be prevented by changing the system of production.

Fallow Bucks Get Hoarse: Vocal Fatigue As A Possible Signal To Conspecifics, Elisabetta Vannoni, Alan G. Mcelligott

Veterinary Science and Medicine Collection

Many studies of sexually selected vocal communication assume that calls remain stable throughout the breeding season. However, during this period, physiological and social factors change and these can have strong effects on the structure of calls and calling rates. During the rut, fallow bucks, Dama dama, reduce their feeding and increase the time and energy spent on vocalizing and fighting to gain matings, and consequently their body condition declines greatly. The availability of matings and intensity of competition between males also change. Therefore, we predicted that male vocal signalling would vary over time in response to the changing intersexual and …

Interests And Harms In Primate Research, Nathan Nobis

Experimentation Collection

The article discusses the moral issues on primate research in reference to the moral defenses by Sughrue and colleagues. It states that Sughrue and colleagues have claimed to provide equal examination of the primate stroke research's ethics. It mentions that the promise to straighten out a number of ethical arguments in favor and against primate research was not fulfilled. Several moral arguments are presented in response to Sughrue and colleagues' moral defense for animal experimentation.

Effect Of Noxious Stimulation Upon Antipredator Responses And Dominance Status In Rainbow Trout, Paul J. Ashley, Sian Ringrose, Katie L. Edwards, Emma Wallington, Catherine R. Mccrohan, Lynne U. Sneddon

Aquaculture Collection

A potentially painful experience may modify normal behavioural responses. To gauge the importance of pain relative to predation or social status, we presented competing stimuli, a predator cue or an unfamiliar social group, to two groups of noxiously treated rainbow trout, Oncorhynchus mykiss. In the predator cue experiment, fish were classified as bold or shy. Noxiously stimulated fish did not show antipredator responses, suggesting that pain is the imperative. In the social status experiment, noxiously stimulated fish held individually and undisturbed showed an increase in respiration rate and plasma cortisol. As a comparison, we used the dominant or subordinate fish …

From Traumatic Brain Injury To Posttraumatic Epilepsy: What Animal Models Tell Us About The Process And Treatment Options, Asla Pitkänen, Riikka J. Immonen, Olli H.J. Gröhn, Irina Kharatishvili

Biomedicine and Animal Models in Research Collection

A large number of animal models of traumatic brain injury (TBI) are already available for studies on mechanisms and experimental treatments of TBI. Immediate and early seizures have been described in many of these models with focal or mixed type (both gray and white matter damage) injury. Recent long-term video-electroencephalography (EEG) monitoring studies have demonstrated that TBI produced by lateral fluid-percussion injury in rats results in the development of late seizures, that is, epilepsy. These animals develop hippocampal alterations that are well described in status epilepticus–induced spontaneous seizure models and human posttraumatic epilepsy (PTE). In addition, these rats have damage …

The Effects Of The Acetic Acid “Pain” Test On Feeding, Swimming, And Respiratory Responses Of Rainbow Trout (Oncorhynchus Mykiss): A Critique On Newby And Stevens (2008), Lynne U. Sneddon

Experimentation Collection

Newby and Stevens’ (2008) paper ‘‘The effects of the acetic acid ‘pain’ test on feeding, swimming, and respiratory responses of rainbow trout (Oncorhynchus mykiss)’’ examines the effects of a noxious stimulus on the behaviour of trout in an attempt to replicate research conducted in my laboratory (Sneddon, 2003a; Sneddon, 2007; Sneddon et al., 2003a,b; Reilly et al., 2008). However, the authors used a different protocol to the one already published and I would like to respond to some of their points of discussion to provide scientific explanations for their results using data from my laboratory. The authors show that swimming …

Resolving Animal Distress And Pain: Principles And Examples Of Good Practice In Various Fields Of Research, Alicia Karas, Matthew C. Leach, Karl A. Andrutis, Kathleen Conlee, John P. Gluck, Andrew N. Rowan, Martin L. Stephens

Laboratory Experiments Collection

Pain and distress are central topics in legislation, regulations, and standards regarding the use of animals in research. However, in practice, pain has received greatly increased attention in recent years, while attention to distress has lagged far behind, especially for distress that is not induced by pain. A contributing factor is that there is less information readily available on distress, including practical information on its recognition, assessment and alleviation.

This chapter attempts to help fill that void by reversing the usual pattern and giving greater attention to distress than to pain. In addition, we also bypass the pain versus distress …

Measurement And Mitigation Of Laboratory Animal Distress Sources Of Distress In The Animal Laboratory, Larry Carbone

Laboratory Experiments Collection

Pain and distress differ, but overlap. For the purposes of this discussion, we will consider pain to involve nociceptive input of stimuli that are potentially tissue damaging, and that further include an unpleasant emotional component (Merskey and Bogduk 1994). Pain need not necessarily induce distress, as when an animal or human willingly undergoes some painful situation in order to achieve a desired reward. In that case, while the pain may be unpleasant, it is not so severe as to be intolerable. Likewise, there are many potential causes of distress that do not involve physical pain.

Personal Reflections On Russell And Burch, Frame, And The Hsus, Martin Stephens

Animal Welfare Collection

The coincidence of anniversaries associated with the publication of William Russell and Rex Burch’s The Principles of Humane Experimental Technique, the founding of the Fund for the Replacement of Animals in Medical Experiments (FRAME), and the establishment of the collaboration between FRAME and the University of Nottingham, provides an opportunity to reflect on Russell and Burch’s legacy and how it was carried forward by FRAME. The Principles, published in 1959, was the pioneering work in what later became the alternatives or Three Rs field of replacement, reduction, and refinement of animal use. Such was the book’s initial and undeserved obscurity, …
