Population Maintenance Of The Scyphozoan Cyanea Sp. Settled Planulae And The Distribution Of Medusae In The Niantic River, Connecticut, Usa, Sean Colin, Patricia Krener

Arts & Sciences Faculty Publications

Scyphozoan jellyfish are seasonally conspicuous in coastal waters, but relatively little is known about the factors that control their distribution and population dynamics.Cyanea sp is a seasonally abundant medusa in the Niantic River, Connecticut, U.S. and appears to maintain a population entirely within the estuary. To better understand the factors controlling their occurrence, we examined the temporal and spatial distribution of settled scyphistomae in relation to that of the medusae. Planula settlement patterns mirrored the presence of mature female medusae. The planulae settled primarily near the bottom. After settlement, planulacysts and polyps on the settlement plates were out competed …

Mutagenic Stabilization And/Or Disruption Of A Cd4-Bound State Reveals Distinct Conformations Of The Human Immunodeficiency Virus Type 1 Gp120 Envelope Glycoprotein, Shi-Hua Xiang, Peter D. Kwong, Rishi Gupta, Carlo D. Rizzuto, David J. Casper, Richard Wyatt, Liping Wang, Wayne A. Hendrickson, Michael L. Doyle, Joseph Sodroski

Nebraska Center for Virology: Faculty Publications

The human immunodeficiency virus type 1 (HIV-1) gp120 exterior envelope glycoprotein is conformationally flexible. Upon binding to the host cell receptor CD4, gp120 assumes a conformation that is recognized by the second receptor, CCR5 and/or CXCR4, and by the CD4-induced (CD4i) antibodies. Guided by the X-ray crystal structure of a gp120-CD4-CD4i antibody complex, we introduced changes into gp120 that were designed to stabilize or disrupt this conformation. One mutant, 375 S/W, in which the tryptophan indole group is predicted to occupy the Phe 43 cavity in the gp120 interior, apparently favors a gp120 conformation closer to that of the CD4-bound …

Human Immunodeficiency Virus Type 1 (Hiv-1) Tat Induces Nitric-Oxide Synthase In Human Astroglia, Xiaojuan Liu, Malabendu Jana, Subhajit Dasgupta, Sreenivas Koka, Jun He, Charles Wood, Kalipada Pahan

Nebraska Center for Virology: Faculty Publications

Human immunodeficiency virus type 1 (HIV-1) infection is known to cause neuronal injury and dementia in a significant proportion of patients. However, the mechanism by which HIV-1 mediates its deleterious effects in the brain is poorly defined. The present study was undertaken to investigate the effect of the HIV-1 tat gene on the expression of inducible nitric-oxide synthase (iNOS) in human U373MG astroglial cells and primary astroglia. Expression of the tat gene as RSV- tat but not that of the CAT gene as RSV-CAT in U373MG astroglial cells led to the induction of NO production and the expression of iNOS …

The Colored Man Standing By The Punch Bowl, Michael K. Jordan

Faculty Scholarship

This essay will explore racial dissonance and how it affects our thinking about race relations and social policy in America. The first part of this essay will examine the concept of race. Though we often think of race as delineating real characteristics that exist objectively, race is actually a socially created abstraction. In addition, how this abstraction changes over time will also be explored. This is another way of saying that "colored people" has been replaced by the term "black people." The difference between the two terms raises important questions about social policy. Next, this article explores the connection among …

The New Thought Police: Inside The Left’S Assault On Free Speech And Free Minds (Book Review), John W. Teeter Jr

Faculty Articles

Attacks on political correctness have grown both plentiful and rather tiresome. Such tomes occasionally score valid ideological points, but one grows weary of the bitter repetitiveness of it all. The New Thought Police might seem to offer a little novelty to the litany. Bruce is undeniably bright, impassioned, and edgy. Her book, however, is decidedly a mixed bag. The best parts center on her controversial role as a feminist spokeswoman during the O.J. Simpson murder trial. Bruce cogently emphasized that the case was a tragic paradigm of domestic violence rather than a racist conspiracy against a black cultural icon.

Bruce’s …

Composition And Morphology Of The Follicular Basal Lamina During Atresia Of Bovine Antral Follicles, H. F. Irving-Rodgers, M. L. Mussard, J. E. Kinder, R. J. Rodgers

Department of Animal Science: Faculty Publications

The fate of the follicular basal lamina during atresia was investigated using bovine follicles, in which different follicle phenotypes have been observed. These phenotypes include: healthy follicles with rounded basal granulosa cells with an aligned basal lamina or follicles with columnar basal granulosa cells with a basal lamina of many loops (loopy), and atretic follicles in which either the antral granulosa cells (antral atresia) or the basal cells (basal atresia) die first. Loopy lamina and basal atresia occur only in small antral follicles < 5 mm in diameter. Follicles were collected from cattle of unknown reproductive history and processed for immunohistochemistry and electron microscopy, and from animals in which follicle growth had been monitored by daily measurements of follicle diameter by ultrasonography. Electron microscopic observations of dominant follicles during the growth phase, plateau and regression showed that the basal lamina was still visible and intact upon atresia. These follicles had a conventional aligned basal lamina, which they retained, except for some degree of folding, as they progressed into antral atresia. In small follicles (2–5 mm in diameter), the basal cell shape (rounded or columnar) and appearance of the basal lamina (aligned or of many loops) did not appear to be related to the type of atresia. On atresia the follicular basal laminae retained immunoreactive laminin α1 and β2, type IV collagen a1 and nidogen. Laminin α2, which may come from the theca, was present in the follicular basal lamina of only 22% of healthy follicles, but was expressed very commonly in 71% of the atretic follicles. Laminin α2 expression was found in both phenotypes of healthy follicles, antral and basal atretic follicles, and follicles with aligned or loopy basal laminae. It is concluded that the basal lamina is not degraded upon atresia, but does undergo a variety of other changes.

The Use Of X-Ray Computer Tomography For Measuring The Muscularity Of Live Sheep, H. E. Jones, R. M. Lewis, M. J. Young, B. T. Wolf

Department of Animal Science: Faculty Publications

Potential measures of muscularity derived from X-ray computer tomography (CT) were assessed using data for 160 sheep (50 Suffolk males, 50 Suffolk females, 40 Texel males and 20 Charollais males). One-fifth of the lambs within each breed and sex were slaughtered at each of 14,18 or 22 weeks ofage and two-fifths slaughtered at 26 weeks. All lambs were CT scanned prior to slaughter with longitudinal and cross-sectional scans taken at three positions along the body LSth lumbar vertebra (LV5), mid-shaft of the femur (FEM) and ischium USC)]. After slaughter, linear measurements of side length (SL) and M. longissimus thoracis et …

A Description Of The Growth Of Sheep And Its Genetic Analysis, R. M. Lewis, G. C. Emmans, G. Simm

Department of Animal Science: Faculty Publications

The Gompertz is one of a family of growth functions that, when the environment [eg.food, housing) is nonlimiting, provides a useful description of growth as a comparatively simple, single equation. It has three parameters of which the important ones are mature size, A, and the rate parameter, B. Estimates of A and B, however, are highly correlated and defining their separate values for individual animals is problematic. This problem was explored using five methods for estimating the parometers, or transformations ofthem, to describe the growth oftwo genotypes of Suffolk sheep kept under non-limiting conditions. 0 ne genotype was under selection …

Effects Of Breed And Family On Rate Of Copper Accretion In The Liver Of Purebred Charollais, Suffolk And Texel Lambs, N. F. Shuttle, R. M. Lewis, J. Small

Department of Animal Science: Faculty Publications

The feeding of housed lambs on conserved forages and pelleted rations is accompanied by a high risk of chronic cpper (Cu) poisoning (CCP) which might be reduced by seleting sires for low liver Cu status. Livers were therefore retrieved from Suffolk, Texel and Charollais lambs, slaughtered during the course of a performance trial, to ascertain sire and possibly breed effects on the rate of Cu accretion in the liver. In total, 160 livers were obtained, 100 from Suffolk, 40 from Texel and 20 from Charollais lambs, the progeny of 14, eight and eight sires, respectively. Lambs came from three separately …

Effects Of Index Selection On The Carcass Composition Of Sheep Given Either Ad Libitum Or Controlled Amounts Of Food, R. M. Lewis, G. C. Emmans, G. Simm

Department of Animal Science: Faculty Publications

Sheep of a line (S) selected on an index to increase lean weight and decrease fatness at an age, and a control line (C), were given a high quality food at different levels including ad libitum. Live performance was measured from about 21 to 114 kg live weight, The carcasses of each line were analysed for lean, fat and bone at three widely varying weights in both males and females. Level of feeding did not affect the extent to which S was superior to C in either the level of fatness in the carcass (0·86 as much) or the ratio …

Landscaping To Avoid Wildlife Conflicts

Other Bird Strike and Aviation Materials

Wild animals contribute to our enjoyment of nature, and many species add aesthetic value to urban and suburban environments. Landscapes are frequently developed to be “environmentally friendly” by providing food and cover for songbirds, waterfowl, squirrels, and other wildlife. Wild animals can, however, damage property or threaten human health and safety. The presence of undesirable species or animal overpopulation often leads to many common wildlife problems associated with urban landscapes. Equipped with the right information, landscape designers can significantly reduce the potential for wildlife–human conflicts and their resulting impacts on economic interests and public safety.

Ec02-1565 Biology And Management Of Potato Insects, Robert J. Wright, Gary L. Hein, W. Wyatt Hoback, Alexander D. Pavlista

University of Nebraska-Lincoln Extension: Historical Materials

A variety of insects can damage potatoes in Nebraska. Insects may feed directly on the tubers and damage the harvestable crop, or they may indirectly damage the crop by feeding on leaves or stems. If severe enough, indirect damage may reduce harvestable yield and quality. Insect feeding also may be important because some insects (e.g., aphids) may transmit plant diseases such as viruses when they feed, or others (e.g., psyllids) may inject toxins. This publication reviews the identification, biology, and management of common insect pests of potatoes in Nebraska. The basis for a successful integrated pest management (IPM) program for …
