The Future Of The World Health Organization: What Role For International Law?, David P. Fidler Jan 1998

The Future Of The World Health Organization: What Role For International Law?, David P. Fidler

Vanderbilt Journal of Transnational Law

This Article has tried to provide a comprehensive analysis of the role of international law in WHO's future. Whether WHO realizes it, international law has had and will continue to have effects on international health policy. In the future, WHO has a choice: It can continue to act as if international law plays no role in global public health or it can build the commitment and capacity needed to integrate international law into its endeavors and into the creation of global health jurisprudence. Building such commitment and capacity will not resurrect WHO to its past glories, but they may very …

Polyadenylation Of Vesicular Stomatitis Virus Mrna Dictates Efficient Transcription Termination At The Intercistronic Gene Junctions, Leroy N. Hwang, Nathan Englund, Asit K. Pattnaik Jan 1998

Polyadenylation Of Vesicular Stomatitis Virus Mrna Dictates Efficient Transcription Termination At The Intercistronic Gene Junctions, Leroy N. Hwang, Nathan Englund, Asit K. Pattnaik

School of Veterinary and Biomedical Sciences: Faculty Publications

The intercistronic gene junctions of vesicular stomatitis virus (VSV) contain conserved sequence elements that are important for polyadenylation and transcription termination of upstream transcript as well as reinitiation of transcription of downstream transcript. To examine the role of the putative polyadenylation signal 3' AUACU75' at the gene junctions in polyadenylation and transcription termination, we constructed plasmids encoding antigenomic minireplicons containing one or two transcription units. In plasmid-transfected cells, analyses of the bicistronic minireplicon containing the wild-type or mutant intercistronic gene junctions for the ability to direct synthesis of polyadenylated upstream, downstream, and readthrough mRNAs showed that the AUACU …

On The Proper Definition Of Cognitive Ethology, Alan Kamil Jan 1998

On The Proper Definition Of Cognitive Ethology, Alan Kamil

Papers in Behavior in Biological Sciences

The last 20-30 years have seen two “scientific revolutions” in the study of animal behavior: the cognitive revolution that originated in psychology, and the Darwinian, behavioral ecology revolution that originated in biology. Among psychologists, the cognitive revolution has had enormous impact. Similarly, among biologists, the Darwinian revolution has had enormous impact. The major theme of this chapter is that these two scientific research programs need to be combined into a single approach, simultaneously cognitive and Darwinian, and that this single approach is most appropriately called cognitive ethology.

Metazoan Parasites And Other Symbionts Of Cetaceans In The Caribbean, Antonio A. Mignucci-Giannoni, Eric P. Hoberg, Doug Siegel-Causey, Ernest H. Williams Jr.

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The parasite fauna in cetaceans from Puerto Rico, the Virgin Islands, and the larger Caribbean region is poorly known. We provide the first records for parasite biodiversity among a diverse assemblage of cetaceans from the Caribbean Sea. Internal and external parasites and commensals were collected from stranded whales and dolphins salvaged in Puerto Rico, the United States and British Virgin Islands, Jamaica, and Venezuela between 1989 and 1997. A total of 47 individuals of 16 species of whales and dolphins (15 odontocetes and one mysticete) were examined. Overall, parasites and commensals were found in 34 (72.3%) animals, representing 13 species …

Mummies And Mummification Practices In The Southern And Southwestern United States, Mahmoud Y. El-Najjar, Thomas M. J. Mulinski, Karl Reinhard Jan 1998

Mummies And Mummification Practices In The Southern And Southwestern United States, Mahmoud Y. El-Najjar, Thomas M. J. Mulinski, Karl Reinhard

Karl Reinhard Publications

Mummification was not intentional for most North American prehistoric cultures. Natural mummification occurred in the dry areas of North America, where mummies have been recovered from rock shelters, caves, and overhangs. In these places, corpses desiccated and spontaneously mummified. In North America, mummies are recovered from four main regions: the southern and southwestern United States, the Aleutian Islands, and the Ozark Mountains of Arkansas. This chapter is limited to a discussion of burial practices and a tabulation of the location of mummies in the southwestern United States with some comments on mummies of the southern United States, including the Ozarks.

New Investigative Techniques [In Mummies, Disease & Ancient Cultures], Theodore A. Reyman, Henrick Nielsen, Ingolf Thuesen, Derek N. H. Notman, Karl Reinhard, Edmund Tapp, Tony Waldron

Karl Reinhard Publications

In this chapter, we shall see how the amplification of minute amounts of genetic material by the polymerase chain reaction (PCR) has enabled researchers to identifY both native and infectious DNA in these bodies. The use of amplified bacterial and viral DNA may turn out to be Aidan Cockburn's 'magic bullet' for solving some of the mysteries of infectious disorders in ancient populations. In the same fashion, native DNA may give us clues to a variety of genetic abnormalities that existed in those distant times. These newer techniques will be the focus of the revised technical section in this second …

Human Dental Microwear Caused By Calcium Oxalate Phytoliths In Prehistoric Diet Of The Lower Pecos Region, Texas, Dennis Danielson, Karl Reinhard Jan 1998

Human Dental Microwear Caused By Calcium Oxalate Phytoliths In Prehistoric Diet Of The Lower Pecos Region, Texas, Dennis Danielson, Karl Reinhard

Karl Reinhard Publications

Recent research demonstrates that silica phytoliths of dietary origin are associated with microwear of human teeth. Previous research has shown that severe enamel microwear and dental wear characterizes Archaic hunter-gatherers in the lower Pecos region of west Texas. Calcium oxalate crystals are especially common in Archaic coprolites. The vast majority are derived from prickly pear and agave, which were the dietary staples in west Texas for 6,000 years. The calcium oxalate phytoliths are harder than enamel. Therefore, calcium oxalate crystals are the most likely source of previously documented dental microwear and wear in the lower Pecos region.Am J Phys Anthropol …

Comparisons Of Two Polymorphic Species Of Ostertagia And Phylogenetic Relationships Within The Ostertagiinae (Nematoda: Trichostrongyloidea) Inferred From Ribosomal Dna Repeat And Mitochondrial Dna Sequences, Dante S. Zarlenga, Eric P. Hoberg, Frank Stringfellow, J. Ralph Lichtenfels Jan 1998

Comparisons Of Two Polymorphic Species Of Ostertagia And Phylogenetic Relationships Within The Ostertagiinae (Nematoda: Trichostrongyloidea) Inferred From Ribosomal Dna Repeat And Mitochondrial Dna Sequences, Dante S. Zarlenga, Eric P. Hoberg, Frank Stringfellow, J. Ralph Lichtenfels

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The first internal transcribed spacer DNA (ITS-1) (rDNA) and the mitochondrial (mt) DNA-derived cytochrome oxidase I gene (COX-1) were enzymatically amplified, cloned and sequenced from 6 nominal species of Ostertagiinae as well as Haemonchus contortus and Haemonchus placei. The portion of the COX-1 gene analyzed was 393 base pairs (bp) in length and contained 33 within species polymorphic base changes at 28 synonymous sites. The ITS-1 rDNA consensus sequences ranged from 392 bp (Ostertagia ostertagi/Ostertagia lyrata, Teladorsagia circumcincta) to 404 bp (H. contortus, H. placei). These data were used both in …

The Effectiveness Of A Strength Training Program On Extremity Strength, Flexibility, And Balance Of Elderly Women, Patricia L. Murphy Jan 1998

The Effectiveness Of A Strength Training Program On Extremity Strength, Flexibility, And Balance Of Elderly Women, Patricia L. Murphy

Master's Projects

This quasi-experimental study, partially replicating that of Nelson and Wernick (1997), compares balance, flexibility, and extremity strength before and after an 8-week weight-bearing exercise class. Six women, aged 69 to 85, used 1-5 pound wrist weights and ankle weights up to 1 o pounds. Pre-and post-exercise measurements of biceps curls, seated leg lifts with weights, one leg stand, and seated stretches were gathered. Results showed improvement in every category, with the greatest improvement (41.6%) in balance and the least (8.3%) in trunk flexibility. Nursing is uniquely positioned to assist this population by promoting, developing, and implementing such exercise programs.

A Diachronic Analysis Of Porotic Hyperostosis In Prehistoric Populations Of Northern Chile, Maria Sloan Hart Jan 1998

A Diachronic Analysis Of Porotic Hyperostosis In Prehistoric Populations Of Northern Chile, Maria Sloan Hart

UNLV Retrospective Theses & Dissertations

A macroscopic analysis of 604 skeletal remains was undertaken at the Museo Arqueologico de San Miguel de Azapa (MASMA) in order to ascertain the rates of porotic hyperostosis in the prehistoric populations of northern Chile. Porotic hyperostosis has been recognized as being a useful indicator of nutritional stress, in particular, iron-deficiency anemia. In the Americas, this pathology has primarily been associated with maize-dependency and pathogen load. Contrary to expectations, results reveal that pre-agricultural populations have 93% of porotic hyperostosis while the agricultural populations show a rate of 66%. This data does not support the maize-dependency model. It is suggested, instead, …

Medical Paradigms For Counseling: Giving Clients Bad News, Linda F. Smith Jan 1998

Medical Paradigms For Counseling: Giving Clients Bad News, Linda F. Smith

Clinical Law Review

The paradigm of a professional delivering "bad news," while not current in legal counseling, has become an important paradigm in the medical world. Medical professionals see counseling as typically beginning with a diagnosis; and sometimes that diagnosis is upsetting to the patient. Hence oncologists tell patients of their cancer, geneticists tell parents their infant has Down syndrome, and emergency room staff tell relatives about accidents and death. Usually these medical professionals also offer choices- choices among therapies, pain management techniques and support systems. But before the counselor offers alternatives, she must deliver the "bad news." This paper draws upon the …

Diphtheria Toxin Fusion Proteins, Frank Foss, Mansoor Saleh, James Krueger, John Nichols, John Murphy Jan 1998

Diphtheria Toxin Fusion Proteins, Frank Foss, Mansoor Saleh, James Krueger, John Nichols, John Murphy

Haematology and Oncology, East Africa

Two different approaches have been undertaken to develop targeted biomolecules for therapeutics. The first was the construction of immunotoxins consisting of monoclonal antibodies chemically linked through a disulfide bond to a plant or bacterial toxin or radionuclide. Instability of the chemical conjugation of some of the earlier immunotoxins led to the concept of using protein engineering and recombinant DNA to assemble fusion genes combining the sequences for the enzymatically active and translocation domains of a toxin with those of a specific targeting ligand. From the outset, the prospect of using recombinant DNA methods to assemble the structural genes encoding bacterial …

Biology And Ecology Of The Anopheles Quadrimaculatus Sibling Species Complex In Louisiana., Cynthia Roxanne Rutledge Jan 1998

Biology And Ecology Of The Anopheles Quadrimaculatus Sibling Species Complex In Louisiana., Cynthia Roxanne Rutledge

LSU Historical Dissertations and Theses

A polymerase chain reaction method for identifying individuals in the Anopheles quadrimaculatus Say sibling species complex was validated for wild mosquitoes from Louisiana and Mississippi. This method distinguished An. quadrimaculatus species A, B, C, and D by detecting species-specific differences in the 2nd internal transcribed spacer of ribosomal DNA and was 100% specific and 95% sensitive. A polymerase chain reaction assay that detects differences in the second internal transcribed spacer of ribosomal DNA was tested for its usefulness in identifying all immature stages of two representatives in the An. quadrimaculatus sibling species complex. The technique was successful in amplifying DNA …

Stretching The Limits Of The Ada: Asymptomatic Hiv-Positive Status As A Disability In Bragdon V. Abbott, 118 S. Ct. 2196 (1998), Teresa A. Schneider Jan 1998

Stretching The Limits Of The Ada: Asymptomatic Hiv-Positive Status As A Disability In Bragdon V. Abbott, 118 S. Ct. 2196 (1998), Teresa A. Schneider

Nebraska Law Review

This Note points out problems with the Bragdon v. Abbott Supreme Court decision and ultimately argues that an asymptomatic HIV-positive person is not disabled under the first definition of disability contained in the Americans with Disabilities Act (ADA); that is, “a physical or mental impairment that substantially limits one or more of the major life activities of such individual.” An asymptomatic HIV-positive individual is not disabled within that definition because, even though he or she suffers from a physical impairment, the impairment does not substantially limit any major life activity. Although this Note rejects the argument that reproduction is a …
