To determine whether the amino acid pattern of human milk is unique, we compared the amino acid pattern of human milk with the amino acid patterns of the milks of great apes (chimpanzee and gorilla), lower primates (baboon and rhesus monkey) and nonprimates (cow, goat, sheep, llama, pig, horse, elephant, cat and rat). Amino acid pattern was defined as the(More)
We address the strategies to prevent disease transmission from human to non-human primates in natural settings. Some field research methods, such as gaining close proximity for observation, provisioning for habituation, or reintroducing for repopulation, may place primate subjects at risk for acquiring human-carried diseases. Additional risks arise through(More)
Granulysin and NK-lysin are antimicrobial proteins found in the granules of human and swine cytotoxic lymphocytes. A murine counterpart to granulysin has not been identified to date, indicating the importance of additional models to fully characterize the role of granulysin-like molecules in the immune response to infectious disease. Two partial nucleotide(More)
Although technology adoption has been the subject of a great deal of economic research, that focused on the economics of adoption of low-input "sustainable" systems has been much more limited and recent. This paper attempts to explain the recent decline in the use of cover crops using in maize farming in the Department of Athlntida, Honduras. In the early(More)
Improved methods for culturing spermatogenic cells will facilitate the study of spermatogenesis, treatment of male factor infertility, and genetic modification of the male germ line. The objective of this study was to develop a procedure for achieving male germ cell progression through meiosis in vitro. Testes from 3-day-old bulls were decapsulated and(More)
OBJECTIVES Research suggests that the use of lies and deception are prevalent in dementia care settings. This issue has been explored from the view point of carers and professionals, and the acceptability and ethicality of deception in dementia care remains an area of heated debate. This article explored the issue of lies and deception in dementia care from(More)
INTRODUCTION Caring for people with dementia incurs significant stress for carers. Stress has been related to the duration of caring role, the number of weekly hours provided and severity of cognitive impairment. What remains less clear is the impact of neuropsychiatric symptoms and subtype of dementia on carer stress and this study aimed to examine these.(More)
In the Luangwa Valley, Zambia, persistent poverty and hunger present linked challenges to rural development and biodiversity conservation. Both household coping strategies and larger-scale economic development efforts have caused severe natural resource degradation that limits future economic opportunities and endangers ecosystem services. A model based on(More)
Although the T cell dependence of autoimmune responses in connective tissue diseases has been well established, limited information exists regarding the T cell targeting of self Ags in humans. To characterize the T cell response to a connective tissue disease-associated autoantigen, this study generated T cell clones from patients using a set of peptides(More)
Requirements for human Th17 differentiation in the context of activated dendritic cells (DCs) are still emerging. Here, we demonstrate that several Toll-like receptor (TLR) ligands, particularly LPS and a synthetic lipoprotein, activate human DCs to direct increased human Th17 differentiation. Based on neutralization studies, IL1, IL6, and TGFbeta(More)
