Institutional Animal Care And Use Committees: A Flawed Paradigm Or Work In Progress?, John P. Gluck, F. Barbara Orlans

Animal Welfare Collection

In his challenging article, Steneck (1997) criticized the creation of the Institutional Animal Care and Use Committee (IACUC) system established by the 1985 amendments to the Animal Welfare Act. He saw the IACUC review and approval of biomedical and behavioral research with animals as an unnecessary "reassignment" of duties from existing animal care programs to IACUC committees. He argued that the committees are unable to do the work expected of them for basically three reasons: (a) the membership lacks the expertise in matters relevant to animal research and care, (b) there exists an inherent and disabling conflict of interest, and …

Effect Of Room Arrangement And Blood Sample Collection Sequence On Serum Thyroid Hormone And Cortisol Concentrations In Cynomolgus Macaques (Macacafascicularis), Bryan L. Flow, John T. Jaques

Research Methodology and Laboratory Animals Collection

We evaluated the relationship, in cynomolgus macaques (Macacafascicularis), between rank for order of blood collection with serum concentrations of 3,5,3'-triiodothyronine (T3), thyroxine (T4), free thyroxine (FT4), and serum cortisol. These relationships were determined for males and females that were housed in two room arrangements. For both room arrangements, males and females were housed separately. For room arrangement 1, macaques were housed on both sides of the animal holding room. The sides of the animal holding room were designated as side A or side B. Blood was initially collected from animals on side A, then from animals on side B. Animals …

Preference For Flavoured Foods By Lambs Conditioned With Intraruminal Administration Of Nitrogen, Juan J. Villalba, Frederick D. Provenza

Behavioral Education for Human, Animal, Vegetation, and Ecosystem Management (BEHAVE)

We suggested that food preference depends on the interplay between flavour and post-ingestive effects, and we predicted that protein-restricted lambs would acquire preferences for foods paired with supplemental sources of N, including urea (Expts 1 and 2), casein (Expt 3), and gluten (Expt 4). In each experiment, twenty lambs, in two groups of ten, were conditioned as follows: on odd-numbered days, lambs in group 1 received wheat straw (Expts 1, 3, and 4) or ground barley (Expt 2) flavoured with a distinctive flavour, and lambs in group 2 received the same food but with a different flavour. On even-numbered days, …

Preference For Wheat Straw By Lambs Conditioned With Intraruminal Infusions Of Starch, Juan J. Villalba, Frederick D. Provenza

Behavioral Education for Human, Animal, Vegetation, and Ecosystem Management (BEHAVE)

We hypothesized that feed preference depends on the interplay between flavour and postingestive effects, and we tested two predictions based on this hypothesis: (1) lambs acquire preferences for poorly nutritious feeds paired with starch; and (2) preferences persist when starch is no longer administered. Twenty lambs were randomly allocated to two groups and conditioned as follows: on odd-numbered days, lambs in group 1 received onion-flavoured wheat straw and lambs in group 2 received oregano-flavoured wheat straw. On even-numbered days, the flavours were switched and starch (2.5-9.4% of the digestible energy received/d) was infused into the rumen of all animals during …

The Effect Of Disturbance On The Reproduction And Management Of Captive Cranes, Claire M. Mirande, James W. Carpenter, Ann M. Burke

Proceedings of the North American Crane Workshop

A retrospective analysis of egg laying histories and observations of crane pairs at the International Crane Foundation and the Patuxent Wildlife Research Center indicates that disturbance associated with captivity has adverse impacts on captive breeding. Females on public display laid significantly fewer eggs than those off display (P < 0.05). Crane pairs moved to other pens (other than adjacent pens) or hetween facilities laid slightly fewer eggs than those birds which were not moved. although the results were not statistically significant (P = 0.188). Pen design and construction also appeared to have adverse impacts on breeding. In addition, human activities, intraspecific interactions, and rearing methods influence a bird's response to disturbance, and, therefore, these factors must also be considered in an effective crane management program. Modifying procedures to minimize disturbance, timing necessary disturbances after the breeding and molt seasons, and carefully monitoring birds for signs of stress can result in increased reproductive potential for captive, endangered cranes.

Schizophrenia: An Integrative Study Of Biological Liabilities And Neurological Causes, Daniel J. Knoblach

Honors Theses, 1963-2015

Society has become increasingly aware of the frustrating and confusing disorders that can result when the brain loses control of its intricate mechanisms. One such disorder that continues to baffle experts is schizophrenia. Schizophrenia is a serious thought disorder characterized by a broad spectrum of cognitive and emotional dysfunctions that disrupts a person's perception of the world into one of tormenting psychotic experience. Schizophrenia results from a variety of complex causes with each possibly contributing something to the disorder. A multifactorial threshold model explains causation by demonstrating that a sum of biological liabilities (genetics and prenatal developmental problems) may take …

Richard W. Pohl: Distinguished Botanist, Marjorie Conley Pohl

Journal of the Iowa Academy of Science: JIAS

In her biographical portrait of Dr. Richard W. Pohl, Mrs. Pohl provides an engaging personal perspective of her late husband, his development as a botanist, his career, and his family life. We gain a sense of Dr. Pohl as a dedicated scientist as well as a humanist. Although Dr. Pohl possessed an abiding curiosity regarding all things natural, he is best known and remembered for his focus on grasses. As Mrs. Pohl documents, this interest in grasses began in the late 1930's and continued throughout his life-ultimately he was regarded as an authority on grass taxonomy both nationally and internationally. …

Ec97-276 Management Strategies For Pen-Mating Female Pigs, Donald G. Levis

University of Nebraska-Lincoln Extension: Historical Materials

The master control switch of a pork production enterprise is weaning day. Pork production managers have little or no control concerning when a weaned female will cycle or how long she will be in estrus after weaning. When females are pen-mated, the producer needs to use management procedures to prevent an excessive number of estrous females from expressing the standing response at the same time, try to manage estrous females so that they are bred at the proper time, try to manage boars so they maintain an adequate level of fertility, evaluate boars for level of sexual behavior before and …

Book Review - The End Of Science: Facing The Limits Of Knowledge, David Lopatto

Journal of the Iowa Academy of Science: JIAS

The June, 1997 issue of Harper's Magazine included a list of recently published books that have titles beginning with "The End of". There are thirty-one titles on the list. Publishers have been rushing to cash in on the public's emotional reaction to the coming end of the century. It is difficult to take some of these works seriously. Perhaps the hardest thesis to swallow is that science, including physics, chemistry, biology, and neuroscience, not to mention the social sciences and the philosophy of science, is coming to an end just as our somewhat arbitrary calendar ticks over to a new …

Prediction Of Potential Antimigraine Activity Using Artificial Neural Networks, Qing Luo, Jerry A. Darsey, Cesar M. Compadre, Sanjay K. Mitra

Journal of the Arkansas Academy of Science

More than 10 million Americans, three quarters of them women, suffer some degree of recurrent migraine headaches. Feverfew [Tanacetum parthenium (L.) Schultz-Bip.) is a member of the Asteraceae family that is native to Europe. This plant is a perennial flowering aromatic plant common in gardens. It has been widely used as a self-medication of arthritis, fever, and migraine headaches for over 2000 years. Sesquiterpene lactones (SL) are the components responsible for the antimigraine activity of feverfew. In this research, the relationship between SL structural information and their biological activity was studied by using Gaussian 92 program in conjunction with artificial …

Circadian Phase Shifts To Neuropeptide Y In Vitro: Cellular Communication And Signal Transduction, Stephany M. Biello, Diego A. Golombek, Kathryn M. Schak, Mary E. Harrington

Psychology: Faculty Publications

Mammalian circadian rhythms originate in the hypothalamic suprachiasmatic nuclei (SCN), from which rhythmic neural activity can be recorded in vitro. Application of neurochemicals can reset this rhythm. Here we determine cellular correlates of the phase-shifting properties of neuropeptide Y (NPY) on the hamster circadian clock in vitro. Drug or control treatments were applied to hypothalamic slices containing the SCN on the first day in vitro. The firing rates of individual cells were sampled on the second day in vitro. Control slices exhibited a peak in firing rate in the middle of the day. Microdrop application of NPY to the SCN …

Long Bone Fracture Management In A Sandhill Crane: A Case Report, Patrice N. Klein, Dorothy Thompson

Proceedings of the North American Crane Workshop

A 65-day-old, juvenile Mississippi sandhill crane (Grus canadensis pulla) sustained an oblique fracture of the right middiaphyseal femur. Internal fixation by use of an intramedullary pin and full cerclage wire was performed to stabilize the fracture site. Post-operative medical management of these fractures is often unsuccessful due to secondary complications associated with long-term restraint. This report describes the successful recovery of an endangered sandhill crane with a long bone fracture of the pelvic limb through a program of incremental physical therapy beginning 2 weeks post-femoral fracture repair. Sling support, assisted walking, and hydrotherapy were methods effective in preventing …

Diel Activity Patterns And Host Preferences Of Glossina Fuscipes Fuscipes (Diptera: Glossinidae) Along The Shores Of Lake Victoria, Kenya, M. M. Mohamed-Ahmed, A. Odulaja

All Peer-Reviewed Publications

Diurnal activity patterns and host preference of Glossina fuscipes fuscipes Newstead were studied in forest and linear habitats along Lake Victoria shore, Kenya. The objective was to identify the preferred hosts of G. f. fuscipes, the emanations of which may be attractive to this species. Hourly catches of flies in biconical traps were related to changes in the weather and the prevalence of hosts in the vicinity of traps. Flies were mainly active between 0800 and 1600 h, with males peaking around 1100 h and females around 1300 h. Activity of flies correlated directly with light intensity and temperature, but …

Ankle Injuries And Ankle Strength, Flexibility, And Proprioception In College Basketball Players, Kristen A. Payne, Kris E. Berg, Richard W. Latin

Health and Kinesiology Faculty Publications

Injuries to the ankle joint are among the most common of all sport-related injuries. Figures range from 10% to 30% of all injuries and from 5% to 20% of all time-loss injuries.1-9 Athletes participating in sports such as football, soccer, basketball, and volleyball are especially at risk for this type of injury, largely because of the running and jumping involved. In 1977, Garrick3 reported that during any single year of a 6-year period at the University of Washington, at least 16% of all time-loss injuries for all sports involved ankle sprains.

Changes Over Twelve Years In Populations Of Glossina Pallidipes And Glossina Longipennis (Diptera: Glossinidae) Subject To Varying Trapping Pressure At Nguruman, South-West Kenya, R. Brightwell, R. D. Dransfield, P. Stevenson, B. Williams

All Peer-Reviewed Publications

Long term changes in the size of populations of the tsetse Glossina pallidipes Austen and G. longipennis Corti Were monitored over a 12 year period at Nguruman in south-western Kenya. Tsetse populations were subject to droughts of varying intensity and, from 1987, to trapping, initially by a research organization, and later by a community-based development project. Populations were mainly sampled using odour-baited biconical traps, with data from other monitoring traps corrected accordingly. Mark-release-recapture studies were carried out to relate trap catches to absolute population size, and to quantify movement between subpopulations. Trypanosomiasis incidence rates in a herd of local cattle …

Geographic Variation In Host Selection Behaviour And Reproductive Success In The Stemborer Parasitoid Cotesia Flavipes (Hymenoptera: Braconidae), R. P.J. Potting, L. E.M. Vet, W. A. Overholt

All Peer-Reviewed Publications

Local parasitoid populations may be adapted to their sympatric major plant host complex. Parasitoid strains may thus differ in their propensity to search for a particular micro-habitat or host or they may differ in their physiological compatibility with particular plant or host species. Cotesiaflavipes Cameron, a larval parasitoid used worldwide in biological control against tropical stemborers, has a wide host range in diverse habitats. The existence of plant and/or host specific strains in C. flavipes has been postulated. To provide insight into the existence of strains in C. flavipes, we compared the plant/host complex selection behaviour, and physiological compatibility with …

Retention Of Relative Grip Effort For At-Home Isometric Exercise, Janet E. Steele

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

The purpose of this work was to determine if subjects initially trained to use a handgrip dynamometer could learn to perform the exercises at the same relative level of effort with a considerably less expensive substitute device. All subjects trained (4, 2-minute contractions, 30% maximal effort) 3 times per week for 12 weeks. In Study I, Group 1 (n = 13) trained using only the dynamometer while Group 2 (n = 14) trained using both the dynamometer and an egg-shaped substitute item for the first 6 weeks. All subjects then trained using only the egg-shaped item. Grip effort …

Law And Biology: Toward An Integrated Model Of Human Behavior, Owen D. Jones

Vanderbilt Law School Faculty Publications

As first year law students unhappily discover, the meaning of "law" is frustratingly protean, shifting by usage and user. Depending on whom you ask, law is a system of rules, a body of precedents, a legislative enactment, a collection of norms, a process by which social goals are pursued, or some dynamic mixture of these. Law's principal purpose is to define and protect individual rights, to ensure public order, to resolve disputes, to redistribute wealth, to dispense justice, to prevent or compensate for injury, to optimize economic efficiency, or perhaps to do something else. And yet one thing is irreducibly …
