Animal Pleasure And Its Moral Significance, Jonathan Balcombe Jun 2014

Animal Pleasure And Its Moral Significance, Jonathan Balcombe

Jonathan Balcombe, PhD

This paper presents arguments for, and evidence in support of, the important role of pleasure in animals’ lives, and outlines its considerable significance to humankind’s relationship to other animals. In the realms of animal sentience, almost all scholarly discussion revolves around its negative aspects: pain, stress, distress, and suffering. By contrast, the positive aspects of sentience – rewards and pleasures – have been rarely broached by scientists. Yet, evolutionary principles predict that animals, like humans, are motivated to seek rewards, and not merely to avoid pain and suffering. Natural selection favours behaviours that enhance survival and procreation. In the conscious, …


Long Term Recall Of Memory Cd8 T Cells In Mice To First And Third Generation Smallpox Vaccines, Sharone Green, Francis Ennis, Anuja Mathew Jan 2014

Long Term Recall Of Memory Cd8 T Cells In Mice To First And Third Generation Smallpox Vaccines, Sharone Green, Francis Ennis, Anuja Mathew

Sharone Green

Since long-term immunity is a critical component of any effective vaccine, we compared over a 15-month period, the strength, durability and specificity of immunity of an attenuated smallpox vaccine Modified Vaccinia Ankara (MVA) to the New York City Board of Health (NYCBH) vaccine. The frequencies of CD8(+) T cells to an immunodominant CD8 T cell epitope B8R(20-27) remained remarkably stable in mice given either MVA or NYCBH. Both groups were also protected from a lethal intranasal challenge with Western Reserve strain of vaccinia virus (VACV-WR). Cytokine responses to virus-specific peptides were detectable with significant boosting upon challenge. Expression of most …

Electrospray ionisation tandem mass spectrometry has allowed the unambiguous identification andquantification of individual lens phospholipids in human and six animal models. Using this approach ca. 100unique phospholipids have been characterised. Parallel analysis of the same lens extracts by a novel directinsertionelectron-ionization technique found the cholesterol content of human lenses to be significantlyhigher (ca. 6 times) than lenses from the other animals.The most abundant phospholipids in all the lenses examined were choline-containing phospholipids. In rat,mouse, sheep, cow, pig and chicken, thesewere present largely as phosphatidylcholines, in contrast 66% of thetotal phospholipid in Homo sapienswas sphingomyelin, with the most abundant being dihydrosphingomyelins,in …
