Identification Of The Binding Subunit Of The Sigma-Type Opiate Receptor By Photoaffinity Labeling With 1-(4-Azido-2-Methyl[6-3h]Phenyl)-3-(2-Methyl[4,6-3h]Phenyl)Guanidine, Michael Kavanaugh, Barbara C. Tester, Michael W. Scherz, John F. W. Keana, Eckard Weber

Biomedical and Pharmaceutical Sciences Faculty Publications

The sigma-type opiate receptor is a distinct binding site in the brain that may mediate some of the psychotomimetic effects caused by benzomorphan opiates and phencyclidine in humans. We have developed a synthetic, highly selective ligand for this receptor, 1,3-di-o-tolylguanidine (DTG). To identify the binding protein(s) of the sigma receptor, we have now synthesized a radiolabeled azide derivative of DTG, 1-(4-azido-2-methyl[6-3H]phenyl)-3-(2-methyl[4,6-3H]phenyl)-guanidine ([3H]N3DTG). In guinea pig brain membrane binding assays conducted in the dark, [3H]N3DTG bound reversibly, selectively, and with high affinity (Kd = 10 nM) to sigma receptors. The drug specificity profile of reversible [3H]-N3DTG binding was identical to that …

Eavesdropping By Bats: The Influence Of Echolocation Call Design And Foraging Strategy, Jonathan Balcombe, M. Brock Fenton

Sentience Collection

We used playback presentations to free-flying bats of 3 species to assess the influence of echolocation call design and foraging strategy on the role of echolocation calls in communication. Near feeding sites over water, Myotis lucifugus and M. yumanensis responded positively only to echolocation calls of conspecifics. Near roosts, these bats did not respond before young of the year became volant, and after this responded to presentations of echolocation calls of similar and dissimilar design. At feeding sites Lasiurus borealis responded only to echolocation calls of conspecifics and particularly to "feeding buzzes". While Myotis, particularly subadults, appear to use the …

Cloning And Sequencing Of The Genes For Shiga Toxin From Shigella Dysenteriae Type 1, Nancy A. Strockbine, Matthew Jackson, Lawrence Sung, Randall Holmes, Alison D. O'Brien

United States Public Health Resources

The structural genes for Shiga toxin, designated stx A and stx B, were cloned from Shigella dysenteriae type 1 3818T, and a nucleotide sequence analysis was performed. Both stx A and stx B were present on a single transcriptional unit, with stx A preceding stx B. The molecular weight calculated for the processed A subunit was 32,225, while the molecular weight of the processed B subunit was 7,691. Comparison of the nucleotide sequences for Shiga toxin and Shiga-like toxin I (SLT-I) from Escherichia coli revealed that the genes for Shiga toxin and SLT-I were greater than 99% homologous; three nucleotide …

Biotechnology And The Law: Social Responsibility V. Freedom Of Scientific Inquiry?, George P. Smith Ii

Scholarly Articles

At American University in Washington, D.C., on November 20, 1973, Julius Stone presented the tenth annual Mooers Lecture, entitled, "Knowledge, Survival, and the Duties of Science."' The central question and thesis that he propounded could and, indeed, should be raised anew today; they form the very core of the province and function of law, science, and medicine. In our brave new world they point to the leeways of choice and patterns of discourse that exist in grappling with the central issue of social responsibility in scientific inquiry. Perhaps they will assist in forging a consensus opinion for a subsequent course …

The Detection, Pharmacokinetics And Behavioral Effects Of Diisopropylamine Dichloroacetate (Dada) In The Horse: A Preliminary Report, J.-M. Yang, W. E. Woods, T. J. Weckman, T. W. Wood, S.-L. Chang, J. W. Blake, Thomas Tobin

Maxwell H. Gluck Equine Research Center Faculty Publications

1. Drug administration studies using diisopropylamine dichloroacetate (DADA) and diisopropylamine (DIPA) were conducted in Thoroughbred and Standardbred horses to assess physiological effects and develop detection methods.

2. Four horses received 0.08 mg DADA/kg body wt and showed no changes in heart and respiratory rates or body temperature as measured over a 1-hr period after administration. A transient diuretic effect was found to occur in 2 mares dosed with 0.80 mg DADA/kg body wt.

3. A qualitative detection method using thin-layer chromatography was developed to detect DIPA, the major metabolite of DADA in equine urine. A quantitative detection method (lower limit …

Understanding The Psychological Impact Of Aids: The Other Epidemic, Marshall Forstein

New England Journal of Public Policy

HIV has created two epidemics, one of disease, the other the consequence of the psychological response to that disease. Thus far, behavioral change is the only effective means of interrupting the transmission of HIV. The underlying psychological dimensions of the societal and individual responses to AIDS are discussed, with suggestions for how both rational thinking and irrational fears and anxiety contribute to the development of public policy. Examples are given of how short-term solutions to reduce anxiety may actually create long-term problems, potentially increasing the risk of transmission of HIV. Specific psychological mechanisms that contribute to the epidemic of fear …

Ethical Issues In Aids Research, Michael A. Grodin, Paula V. Kaminow, Raphael Sassower

New England Journal of Public Policy

There is a need for carefully controlled and scientifically rigorous research studies of the acquired immunodeficiency syndrome (AIDS). The morbidity and mortality associated with AIDS patients and the public health concerns for control of this epidemic have distorted the usual process of research. The Institutional Review Board at Boston City Hospital is suggested as an appropriate mechanism for clarifying the distinctions between research and innovative therapies and for assuring the protection of this vulnerable population of research subjects. This article addresses ethical concerns relating to the time frame of research, drug and antibody testing, vaccine trials, and questions of justice …

The Hiv Seropositive State And Progression To Aids: An Overview Of Factors Promoting Progression, Paul H. Black, Elinor M. Levy

New England Journal of Public Policy

We have considered factors that predispose to infection by the human immunodeficiency virus as well as the clinical consequences of infection. We have also reviewed what is known about the virological status of the asymptomatic carrier, particularly the female, and the fact that pregnancy may be a cofactor for progression of HIV disease in seropositive women. Additionally, we have discussed several other cofactors that may promote the progression of HIV infection. These include intercurrent infection, excessive use of recreational drugs and alcohol, malnutrition, and stress. With respect to stress, we have reviewed evidence indicating that certain personality factors, by buffering …

Properties Of Anti-Lyb-2-Mediated B-Cell Activation And The Relationship Between Lyb-2 Molecules And Receptors For B-Cell Stimulatory Factor-1 On Murine B Lymphocytes, Subbarao Bondada, Joan Morris, A. R. Baluyut

Microbiology, Immunology, and Molecular Genetics Faculty Publications

The murine B-cell differentiation antigen Lyb-2 has been shown to be involved in B-lymphocyte activation and has been postulated by some to be related to a receptor for B-cell stimulatory factor I (BSF-1) (H. Yakura et al., J. Immunol. 137, 1475, 1986). Here we have demonstrated that monoclonal antibody (mAB) to Lyb-2 resembles BSF-1 in its ability to activate small resting B cells and enhancement of surface Ia. Anti-Lyb-2 antibodies bound B cells with very high avidity and were able to induce mobilization of cytosolic-free calcium. Anti-Lyb-2 mAB differs from BSF-1 in that BSF-1 but not anti-Lyb-2 is able to …

Impaired Autoreactive T Cell-Induced T Cell-T Cell Interaction In Aged Mice, Venkatachalam Udhayakumar, Subbarao Bondada, Aruna Seth, Mitzi Nagarkatti, Prakash S. Nagarkatti

Microbiology, Immunology, and Molecular Genetics Faculty Publications

Self-Ia-reactive (autoreactive) L3T4⁺ T cell clones have been shown earlier to stimulate the proliferation of syngeneic naive L3T4⁺ T cells and initiate a T cell-T cell (T-T) interaction leading to the generation of immunoregulatory circuits. Since aging has been shown to be associated with a decline of the immune responsiveness, age-related alterations in the T-T interaction was investigated in the present study. Using several I-E^d-specific autoreactive T cell clones isolated from 2- to 3-month-old (young) DBA/2 mice as stimulators, it was observed that L3T4⁺ T cells from 22- to 24-month-old (aged) DBA/2 mice, failed to …

Improved Selective Medium For The Isolation Of Treponema Hyodysenteriae, Robert A. Kunkle, J. M. Kinyon

School of Veterinary and Biomedical Sciences: Faculty Publications

An agar medium with improved selection for Treponema hyodysenteriae was developed. Cultures of T. hyodysenteriae and T. innocens, feces from 11 clinically normal pigs, and colonic contents from 6 pigs with gross lesions consistent with swine dysentery were diluted in phosphate-buffered saline and plated on Trypticase soy agar (BBL Microbiology Systems, Cockeysville, Md.) with 5% citrated bovine blood (TSA), TSA with 400 ,ug of spectinomycin per ml (TSA-S400), TSA-S400 with 25 ,ug each of colistin and vancomycin per ml, and TSA with 5% pig feces extract and five antimicrobial agents (spiramycin, rifampin, vancomycin, colistin, and spectinomycin) (BJ).

"Cradled On The Sea": Positive Images Of Prison And Theories Of Punishment, Martha Grace Duncan

Faculty Articles

This interdisciplinary study investigates the meanings of incarceration through an analysis of prison memoirs and novels. It argues that many prisoners and nonprisoners exhibit powerful positive associations to penal confinement. The Article draws on psychoanalysis, philosophy, and sociol­ogy to account for the various kinds of attraction that prison exerts. The Article also considers the interrelationships between the analysis of the posi­tive images and three traditional purposes of punishment: rehabilitation, deterrence, and retribution.
