Acquaintance Rape Of College Students, Rana Sampson

United States Public Health Resources

Rape is the most common violent crime on American college campuses today. This guide describes the problem of acquaintance rape of college students, addressing its scope, causes and contributing factors; methods for analyzing it on a particular campus; tested responses; and measures for assessing response effectiveness. With this information, police and public safety officers can more effectively prevent the problem.
Researchers believe that college rape prevention programs, including the most widely used ones, are insufficient. Most rapes are unreported, perhaps giving campus administrators and police the false impression that current efforts are adequate. In addition, campus police may be influenced …

The Ignored Disease: The Aids Epidemic 1981–1987, Heather L. Graff, Heather Graff Bloom

College of Journalism and Mass Communications: Theses

Less than six months after Ronald Reagan was inaugurated as the 40th president of the United States, the federal Centers for Disease Control in Atlanta reported pneumocystis carinii pneumonia, in five gay men. In the United States, AIDS was first diagnosed among gay men in New York City and San Francisco. There were several media trends for AIDS coverage in the 1980s. In the early 1980s, AIDS was mainly thought of as a gay-related disease. In the mid- l 980s, AIDS cases were found in hemophiliacs, intravenous drug users and "celebrities." Coverage in the late 1980s focused on heterosexuals and …

Association Of Borrelia Garinii And B. Valaisiana With Songbirds In Slovakia, Klara Hanincova, Veronika Taragelova, Juraj Koci, Stefanie M. Schafer, Rosie Hails, Amy J. Ullmann, Joseph Piesman, Milan Labuda, Klaus Kurtenbach

United States Public Health Resources

In Europe, 6 of the 11 genospecies of Borrelia burgdorferi sensu lato are prevalent in questing Ixodes ricinus ticks. In most parts of Central Europe, B. afzelii, B. garinii, and B. valaisiana are the most frequent species, whereas B. burgdorferi sensu stricto, B. bissettii, and B. lusitaniae are rare. Previously, it has been shown that B. afzelii is associated with European rodents. Therefore, the aim of this study was to identify reservoir hosts of B. garinii and B. valaisiana in Slovakia. Songbirds were captured in a woodland near Bratislava and investigated for engorged ticks. Questing I. ricinus ticks …

Sodium Tanshinone Iia Sulfonate Mediates Electron Transfer Reaction In Rat Heart Mitochondria, Guangyin Zhou, Wen Jiang, Yan Zhao, Guangén Ma, Wenjuan Xin, Junjie Yin, Baolu Zhao

United States Public Health Resources

In this paper, an electron transfer reaction mediated by sodium tanshinone IIA sulfonate (STS) was studied in rat heart mitochondria. It was found that STS could stimulate mitochondrial NADH oxidation dose-dependently and partly restore NADH oxidation in the presence of respiratory inhibitor (rotenone or antimycin A or KCN). It was likely that STS could accept electrons from complex I similar to ferricyanide and could be converted to its semiquinone form that could then reduce oxygen molecule. The data also showed that cytochrome c (Cyt c) could be reduced by STS in the presence of KCN, or STS could transfer the …

A Preliminary Linkage Map Of The Hard Tick, Ixodes Scapularis, A. J. Ullmann, J. Piesman, M. C. Dolan, W. C. Black Iv

United States Public Health Resources

Blackwell Publishing Ltd. A linkage map of the Ixodes scapularis genome was constructed, based upon segregation amongst 127 loci. These included 84 random amplified polymorphic DNA (RAPD) markers, 32 Sequence-Tagged RAPD (STAR) markers, 5 cDNAs, and 5 microsatellites in 232 F₁ intercross progeny from a single, field-collected P₁ female. A preliminary linkage map of 616 cM was generated across 14 linkage groups with one marker every 10.8 cM. Assuming a genome size of ~ 10 ⁹ bp, the relationship of physical to genetic distance was found to be ~ 300 kb/cM in the I. scapularis genome.

Absence Of Interferon-Γ–Inducible Gene Igtp Does Not Significantly Alter The Development Of Chagasic Cardiomyopathy In Mice Infected With Trypanosoma Cruzi (Brazil Strain), A. P. De Souza, B. Tang, H. B. Tanowitz, S. M. Factor, V. Shtutin, J. Shirani, G. A. Taylor, L. M. Weiss, L. A. Jelicks

United States Public Health Resources

Interferon-γ (IFN-γ) contributes to host resistance during acute infection with Trypanosoma cruzi, the causative agent of Chagas’ disease. Inducibly expressed guanosine triphosphatase (IGTP), a 48-kDa guanosine triphosphatase (GTPase), is a member of a family of GTPase proteins inducibly expressed by IFN-γ. The expression pattern of IGTP suggests that it may mediate IFN-γ–induced responses in a variety of cell types. IGTP has been demonstrated to be important for control of Toxoplasma gondii infection but not for resistance against Listeria monocytogenes. We evaluated the role of IGTP in development of chronic chagasic cardiomyopathy in IGTP null mice and C57X129sv (wild …

United States Public Health Resources

Ovarian cancer is the fifth most common cancer among U.S. women.¹ An estimated 23,400 new cases were expected to be diagnosed in the U.S. in 2001. As is the case for breast and endometrial cancers, ovarian cancer is more common among women in northern and central Europe, and North America compared with Africa, South America, and Asia.² In the U.S., substantial racial and ethnic variations also are observed in the incidence of ovarian cancer. rates reportedly are highest among non-Hispanic white and American Indian women, and are lower among Hispanic, Native Hawaiian, and Asian women.³ Among white …

Inhibition Of Markers Of Hepatic Stellate Cell Activation By The Hormone Relaxin, Robert G. Bennett, Kusum K. Kharbanda, Dean J. Tuma

United States Public Health Resources

Hepatic fibrois results from excess extracellular matrix produced primarily by hepatic stellate cells (HSC). In response to injury, HSC differentiate to a myofibroblastic phenotype expressing smooth muscle actin and fibrillar collagens. Relaxin is a polypeptide hormone shown to have antifibrotic effects in fibrosis models. In this study, activated HSC from rat liver were treated with relaxin to determine if relaxin can reverse markers of HSC activation. Relaxin treatment resulted in a decrease in the expression of smooth muscle actin, but had no effect on cell proliferation rate. The levels of total collagen and type I collagen were reduced, while the …

Ethanol Consumption Decreases The Synthesis Of The Mannose 6-Phosphatelinsulin-Like Growth Factor Ii Receptor But Does Not Decrease Its Messenger Rna, James Haorah, Richard Macdonald, Julie A. Stoner, Terrence M. Donohue, Jr.

United States Public Health Resources

The mannose 6-phosphatelinsulin-like growth factor I1 receptor (M6P/IGF-IIR) is a protein that facilitates the transport of acid hydrolases into the lysosome. We have shown that chronic ethanol consumption lowers the M6P/IGF-IIR content in rat hepatocytes. Here, we determined the steady-state level of mRNA encoding M6P/IGF-IIR, as well as the rate of receptor synthesis, to ascertain whether the ethanol-elicited reduction in receptor protein content is related to changes in either or both of these parameters. Rats were pair-fed the normal carbohydrate (NC) or low carbohydrate high-fat (LC) liquid diets containing either ethanol or isocaloric maltose-dextrin for 7-8 weeks. RNA was isolated …

Impaired Receptor-Mediated Endocytosis By The Asialoglycoprotein Receptor In Ethanol-Fed Mice: Implications For Studying The Role Of This Receptor In Alcoholic Apoptosis, Shana R. Dalton, Robert L. Wiegert, Cheryl R. Baldwin, Karen M. Kassel, Carol A. Casey

United States Public Health Resources

During receptor-mediated endocytosis (RME), extracellular molecules are internalized after being recognized and bound to specific cell surface receptors. In previous studies of the asialoglycoprotein receptor (ASGPR) in rats, we showed that ethanol impairs RME at multiple ASGPR sites. Ethanol administration has been shown to increase apoptosis, and we demonstrated increased sensitization to apoptotic induction in hepatocytes from ethanol-fed rats. Although a physiological role for the ASGPR has not been identified, investigators have shown its involvement in the uptake/clearance of apoptotic cells in vitvo. This suggests a potential role for the ASGPR in the removal of apoptotic cells, and the recent …

Interferon Gamma Enhances Proteasome Activity In Recombinant Hep G2 Cells That Express Cytochrome P4502e1: Modulation By Ethanol, Natalia A. Osna, Dahn L. Clemens, Terrence M. Donohue Jr.

United States Public Health Resources

We tested the influence of IFNγ on proteasome activity in parental Hep G2 cells that do not metabolize ethanol, as well as in recombinant Hep G2-derived cells that express either or both alcohol dehydrogenase (ADH) and cytochrome P4502E1 (CYP2E1). IFNγ treatment increased proteasome activity in VL-17A (ADH⁺, CYP2E1⁺) and E-47 (CYP2E1⁺) cells, but not in Hep G2, VI-R2 (parental cells with empty vectors) or in VA-13 (ADH⁺) cells. Proteasome activation by IFNγ correlated positively with the level of CYP2E1 activity. Treatment of VL-17A cells with agents that inhibit CYP2E1 or the inducible …

Chronic Ethanol Consumption Impairs Receptor-Mediated Endocytosis Of Maa-Modified Albumin By Liver Endothelial Cells, Michael J. Duryee, Lynell W. Klassen, Thomas L. Freeman, Monte S. Willis, Dean J. Tuma, Geoffrey M. Thiele

United States Public Health Resources

Alcoholic liver disease has been associated with abnormalities in receptor-mediated endocytosis (RME) which results in abnormal degradation of metabolically altered proteins. Model systems using formaldehyde-modified albumin (f-Alb) have shown an impairment in RME following chronic alcohol consumption utilizing both in situ perfused rat livers and isolated rat liver endothelial cells (LECs). The discovery that alcohol metabolite derived aldehydes can modify proteins prompted a study to determine if malondialdehyde– acetaldehyde-modified albumin (MAA-Alb) would be degraded similar to that reported for f-Alb, and whether ethanol-fed rats would demonstrate an impaired RME with respect to this ligand which occurs as a consequence of …

Reducing Childhood Pedestrian Injuries: Proceedings Of A Multidisciplinary Conference, Richard A. Schieber, Maria Vegega

United States Public Health Resources

EXECUTIVE SUMMARY
Motor vehicle crashes are associated with one of every five deaths among children 1 to 14 years of age in the United States, and pedestrian injuries account for a third of them. Compared with occupant injuries, pedestrian injuries are more severe; death is five times more likely to occur among those injured. In 1999, 533 child pedestrians were killed, and at least 30,000 children were nonfatally injured in traffic. Another 200 were killed in non-traffic areas, including driveways, sidewalks, and parking lots. Traumatic brain injury accounts for more than half the fatalities.
Dr. Schieber noted that the decline …

Reduced-Median-Network Analysis Of Complete Mitochondrial Dna Coding-Region Sequences For The Major African, Asian, And European Haplogroups, Corinna Herrnstadt, Joanna L. Elson, Eoin Fahy, Gwen Preston, Douglass M. Turnbull, Christen Anderson, Soumitra S. Ghosh, Jerrold M. Olefsky, M. Flint Beal, Robert E. Davis, Neil Howell

United States Public Health Resources

The evolution of the human mitochondrial genome is characterized by the emergence of ethnically distinct lineages or haplogroups. Nine European, seven Asian (including Native American), and three African mitochondrial DNA (mtDNA) haplogroups have been identified previously on the basis of the presence or absence of a relatively small number of restriction-enzyme recognition sites or on the basis of nucleotide sequences of the D-loop region. We have used reduced-median-network approaches to analyze 560 complete European, Asian, and African mtDNA coding-region sequences from unrelated individuals to develop a more complete understanding of sequence diversity both within and between haplogroups. A total of …

Pathogenesis Of Human And Bovine Cryptosporidium Parvum In Gnotobiotic Pigs, Sonia J. Pereira, Norma E. Ramirez, Lihua Xiao, Lucy A. Ward

United States Public Health Resources

To compare the pathogenesis of human genotype 1 (HuGl) and bovine genotype 2 (BoG2) Cryptosporidium parvum, neonatal gnotobiotic pigs were given 1-10 HuGl or BoG2 oocysts. The prepatent and patent periods were significantly longer for HuGl than for BoG2 C. parvum (prepatent, 8.6 vs. 5.6 days; patent, 16.6 vs. 10.3 days). BoG2-infected pigs developed signif- icantly more severe disease than did HuGl-infected pigs. BoG2 parasites were seen micro- scopically throughout the intestines during the prepatent and patent periods. HuGl parasites were only detected during the patent period in the ileum and colon but colonized the mucosal surface in significantly …

The Effects Of Depression And Anxiety On Memory Performance, Ali H. Kizilbash, Rodney D. Vanderploeg, Glenn Curtiss

United States Public Health Resources

The effects of depression and anxiety, as assessed by MMPI D and Pt scales, on memory performance was examined in 3999 veterans who completed the California Verbal Learning Test (CVLT). Depressive symptoms (without anxiety) had an adverse effect on immediate recall of new information and the total amount (but not rate) of acquisition; however, retrieval and retention were unaffected. On the other hand, high levels of anxiety did not have significant detrimental effects on any aspect of memory functioning assessed including immediate recall, total amount acquired, retention, and retrieval of novel information. However, when depression was compounded by anxiety, there …

Chronic Ethanol Administration Decreases The Ligand Binding Properties And The Cellular Content Of The Mannose 6-Phosphatelinsulin-Like Growth Gactor Ii Receptor In Rat Hepatocytes, James Haorah, Daniel L. Mcvicker, James C. Byrd, Richard G. Macdonald, Terrence M. Donohue, Jr.

United States Public Health Resources

We have shown previously that chronic ethanol administration impairs the maturation of lysosomal enzymes in rat hepatocytes. The mannose 6-phosphate/insulin-like growth factor I1 receptor (M6PLGF-IIR) is a protein that facilitates the transport of lysosomal enzymes into the lysosome. Therefore, we examined whether ethanol consumption altered the ligand binding properties and the cellular content of M6P/IGF-IIR. Rats were pair-fed liquid diets containing either ethanol (36% of calories) or isocaloric maltose-dextrin for either 1 week or 5-7 weeks. Hepatocytes prepared from these animals were examined for receptor-ligand binding and receptor content. One week of ethanol feeding had no significant effect on ligand …

United States Public Health Resources

Objective: To develop and implement a system for rating state clean indoor air laws.
Design: The public health interest of state clean indoor air laws is to limit non-smoker exposure to environmental tobacco smoke (ETS). Current estimates of health risks and methods available for controlling ETS provided a framework for devising a ratings scale. An advisory committee applied this scale to each of seven site specific smoking restrictions and two enforcement related items. For each item, a target score of +4 was identified. The nine items were then combined to produce a summary score for each state. A state that …

Inhibition Of Hepatic Stellate Cell Collagen Synthesis By N-(Methy1amino)Isobutyric Acid, Thomas L. Freeman, Kusum K. Kharbanda, Dean Tuma, Mark Milliard

United States Public Health Resources

The increased deposition of extracellular matrix by hepatic stellate cells following liver injury, in a process known as activation, is considered a key mechanism for increased collagen content of liver during the development of liver fibrosis. We report that N- (methylamino)isobutyric acid (MeAIB), a specific inhibitor of System A-mediated amino acid uptake, reduces the accumulation of collagen in CFSC-2G hepatic stellate cell cultures and in a rat model of liver injury and fibrosis. Rat CFSC-2G cells were cultured in 0-5 mM MeAIB, and the accumulation and synthesis of collagen were measured by binding to Sirius red F3B and pulse-labeling with …

Effect Of Malondialdehyde-Acetaldehyde-Protein Adducts On The Protein Kinase C-Dependent Secretion Of Urokinase-Type Plasminogen Activator In Hepatic Stellate Cells, Kusum K. Kharbanda, Kris A. Shubert, Todd A. Wyatt, Michael F. Sorrell, Dean J. Tuma

United States Public Health Resources

Previous studies from our laboratory have shown that malondialdehyde-acetaldehyde-protein adducts (MAA adducts) are formed in hepatocytes of ethanol-fed rats and directly influence the hepatic stellate cells (HSCs) to induce their secretion of chemokines and to up-regulate their expression of adhesion molecules. Since protein kinase C (PKC) is known to play a major role in many diverse intracellular signal transduction processes, we investigated whether MAA adducts influence the function of HSCs via a PKC-dependent pathway. HSCs in culture were exposed to MAA adducts, and PKC activity was determined. We observed a time- and concentration-dependent activation of PKC when cultures were exposed …
