The objective of this study was to evaluate conventional (CONV) and natural (NAT) beef production systems from annual pasture through finishing through grazing. Beef steers (n = 180, initial BW = 250 ± 19 kg) were assigned randomly to 2 treatments in the pasture phase. Steers were implanted with 40 mg of trenbolone acetate (TBA), 8 mg estradiol, and 29 mg tylosin tartrate (CONV), or received no implant (NAT). Steers on the 2 treatments grazed wheat or cereal rye for 109 d. Conventional steers had an 18.5% improvement in ADG (1.22 vs. 1.03 kg/d, P < 0.01) and a heavier final BW (385 vs. 366 kg, P < 0.01) compared with NAT steers. Following the pasture phase, steers (n = 160 steers, 5 steers/pen, 8 pens/treatment) were assigned to a 2 × 2 factorial in the feedlot phase. Production system (NAT vs. CONV) was maintained from the pasture phase, and the second factor was 7 vs. 12% low-quality roughage (DM basis, LOW vs. HIGH). During finishing, CONV steers were given 120 mg of TBA and 24 mg estradiol at processing, fed monensin and tylosin, and fed zilpaterol hydrochloride for the last 20 d of the experiment. There were no program × roughage level interactions (P > 0.07). The CONV steers ate …

Western Immunoblotting In Avian Shell Gland Sample Immunoblotting Methods1, K.K. Hansen, R.J. Kittok, Gautam Sarath, Mary M. Beck

Department of Animal Science: Faculty Publications

Avian shell gland tissue was subjected to Western blot analysis using anti-human estrogen receptor- α antibody H222. Initial attempts to obtain consistent, high-quality blots were unsuccessful because, as it turned out, excessive lipid in tissue preparations interfered with protein separation. Incremental additions of acetone eventually proved to be the critical step in solubilizing lipids and allowing consistent separation of bands on gels. A detailed description of the methodology is presented.

The African Conception Of Death: A Cultural Implication, Lesiba Baloyi, Molebogeng Makobe-Rabothata

Papers from the International Association for Cross-Cultural Psychology Conferences

From an African perspective death is a natural transition from the visible to the invisible spiritual ontology where the spirit, the essence of the person, is not destroyed but moves to live in the spirit ancestors’ realm dead. It signifies an inextricable spiritual connection between the visible and invisible worlds. This chapter focuses on how traditional Africans conceive and deal with the bereavement process. We adopt the African worldview and philosophy as our framework. We dispute the often held view in mainstream psychology that behavior, in this case the concept of death and the bereavement processes have universal applicability, articulation, …

High Prevalence Of Dissociative Amnesia And Related Disorders In Immigrated People, Angelica Staniloiu, Hans J. Markowitsch

Papers from the International Association for Cross-Cultural Psychology Conferences

Across various cultures, dissociative amnesic disorders have been shown to be triggered by psychological stress or trauma. In immigrant populations, stressful experiences can arise during pre-emigration, migration or post-migration phase. Preliminary data suggest that stresses related to various phases of migration and acculturation could trigger dissociative amnesic disorders via a dysregulation of hormonal stress responses. These findings are highly relevant in the era of increased globalization and call for culturally sensitive approaches, in order to accurately diagnose and optimally manage these conditions in the future.

Evaluation Of Three Herbicide Resistance Genes For Use In Genetic Transformations And For Potential Crop Protection In Algae Production, Andrew J. Bruggeman, Daniel Kuehler, Donald P. Weeks

Department of Biochemistry: Faculty Publications

Genes conferring resistance to the herbicides glyphosate, oxyfluorfen and norflurazon were developed and tested for use as dominant selectable markers in genetic transformation of Chlamydomonas reinhardtii and as potential tools for the protection of commercial-scale algal production facilities against contamination by organisms sensitive to these broad-spectrum herbicides. A synthetic glyphosate acetyltransferase (GAT) gene, when fitted with a strong Chlamydomonas promoter, conferred a 2.79-fold increase in tolerance to the EPSPS inhibitor, glyphosate, in transgenic cells compared with progenitor WT cells. A mutant Chlamydomonas protoporphyrinogen oxidase (protox, PPO) gene previously shown to produce an enzyme insensitive to PPO-inhibiting herbicides, when genetically engineered, …

A Model Of The Effect Of Uncertainty On The C Elegans L2/L2d Decision, Leon Avery

Physiology and Biophysics Publications and Presentations

Abstract

At the end of the first larval stage, the C elegans larva chooses between two developmental pathways, an L2 committed to reproductive development and an L2d, which has the option of undergoing reproductive development or entering the dauer diapause. I develop a quantitative model of this choice using mathematical tools developed for pricing financial options. The model predicts that the optimal decision must take into account not only the expected potential for reproductive growth, but also the uncertainty in that expected potential. Because the L2d has more flexibility than the L2, it is favored in unpredictable environments. I estimate …
