Reconstituting identity and history in post-war Mostar, Bosnia-Herzegovina

This paper by Carl Grodach demonstrates the careful unravelling of complexity, diversity, contestation and contradictions involved in the reconstruction of symbolic urban spaces after violent conflict, and the allied processes of cultural reinterpretation, political reconfiguration and material revaluation which accompany it. The paper analyses the reconstruction and redevelopment of the 16th-century historic centre of Mostar, Bosnia-Herzegovina, following the Bosnian Wars of 1992–1995. Reconstruction efforts centre around Stari Most, the 16th-century Ottoman bridge destroyed by Bosnian Croat military in 1993. In Mostar, both international and local organizations are in the process of reinterpreting Bosnia’s legacy of Ottoman city spaces. This research and analysis illuminates how such spaces can be central to contemporary projects to redefine group identities and conceptions of place. It provides insight into the ways various groups are attempting to reshape outside perceptions of the city—and Bosnia’s ethnic conflict—to articulate a new definition of local identity and ethnic relations and to remake a stable tourist economy through Mostar’s urban spaces.

SCWDS BRIEFS: Volume 20, Number 2 (July 2004)

National Veterinary Services Laboratories in Ames, Iowa, confirmed vesicular stomatitis (VS) in horses at one premises in Texas. As of July 21, 2004, infected animals were identified on a total of 45 premises in Colorado (11), New Mexico (21), and Texas (13). These are the first reports of VS in livestock in the United States since the 1998 epizootic. SCWDS VS Studies Chronic Wasting Disease Developments: nearly 118,000 wild white-tailed deer, mule deer, and elk were tested in the United States from October 2002 to September 2003, with 592 animals testing positive for the CWD prion. More than $38,000,000 was spent by federal and state wildlife and animal health agencies on CWD-related activities during this same period. The Second International Chronic Wasting Disease Symposium, hosted by the Wisconsin Department of Natural Resources, will be held in Madison, Wisconsin, July 12-14, 2005. Crow Decoys Used in West Nile Virus Study Although Lyme disease caused by a spirochete bacterium, Borrelia burgdorferi, is relatively rare in the southeastern United States, a Lyme disease-like infection referred to as Southern Tick-Associated Rash Illness (STARI) and thought to be caused by Borrelia lonestari, has been recognized in people in this region. The Ohio Division of Wildlife joined SCWDS as an associate member beginning July 1, 2004. The Final Report of the 2003 Hemorrhagic Disease (HD) Surveillance project has been completed and distributed to all cooperators.

Comparative study on structure and magnetic properties of polycrystalline PrxY1-xBa2Cu3O7-delta prepared in oxygen and argon atmosphere

We report a systematic study on the influence of the synthesis routes on the structural and magnetic properties of polycrystalline PrxY1-xBa2Cu3O7-delta. We have prepared high-quality samples of this material by following a sol-gel method based on heat treatment in both inert argon and oxygen atmospheres in order to compare their effect on the formation of the superconducting phase using X-ray powder diffraction. Magnetic measurements (DC and AC susceptibility) clearly demonstrate that, for the same concentration of Pr, the superconducting transition temperature markedly increases in all samples prepared in argon atmosphere, including pure Pr-123.

A METAGENOMIC STUDY OF THE TICK MIDGUT

A Metagenomic Study of the Tick Midgut Daniel Yuan, B.S. Supervisory Professor : Steven J. Norris, Ph.D. Southern tick–associated rash illness (STARI) or Master’s disease is a Lyme-like illness that occurs following bites by Amblyomma americanum, the lone-star tick. Clinical symptoms include a bull’s eye rash similar to the erythema migrans lesions of Lyme disease, as well as fever and joint pains. Lyme disease is caused by Borrelia burgdorferi and related spirochetes. However, B. burgdorferi has not been detected in STARI patients, or in ticks in the South Central U.S. The causative agent of STARI has not been identified, although it was once thought to be caused by another Borrelia species, Borrelia lonestari. Furthermore, while adult A. americanum have up to a 5.6% Borrelia lonestari infection rate, the prevalence of all Borrelia species in Texas ticks as a whole is not known. Previous studies indicate that 6%-30% of Northern Ixodes scapularis ticks are infected by Borrelia burgdorferi while only 10% of Northern A. americanum and I. scapularis ticks are infected by Borrelia species. The first specific aim of this project was to determine the bacterial community that inhabits the midgut of Texas and Northeastern ticks by using high throughput metagenomic sequencing to sequence bacterial 16S rDNA. Through the use of massively parallel 454 sequencing, we were able to individually sequence hundreds of thousands of 16S rDNA regions of the bacterial flora from 133 ticks from the New York, Missouri and Texas. The presence of previously confirmed endosymbionts, specifically the Rickettsia spp. and Coxiella spp., that are commonly found in ticks were confirmed, as well as some highly prevalent genera that were previously undocumented. Furthermore, multiple pathogenic genera sequences were often found in the same tick, suggesting the possibility of co-infection of multiple pathogenic species. The second specific aim was to use Borrelia specific primers to screen 344 individual ticks from Missouri, Texas and the Northeast to determine the prevalence of Borrelia species in ticks. To screen for Borrelia species, two housekeeping genes, uvrA and recG, were selected as well as the 16S-23S rDNA intergenic spacer. Ticks from Missouri, Texas and New York were screened. None of the Missouri or Texas ticks tested positive for Borrelia spp. The rate of I. scapularis infection by B.burgdorferi is dependent on tick feeding activity as well as reservoir availability. B. burgdorferi is endemic in the Northeast, sometimes reported as highly present in over 50% of all I. scapularis ticks. 11.6% of all New York ticks were positive for a species of Borrelia, however only 6.9% of all New York ticks were positive for B. burgdorferi. Despite being significantly lower than 50%, the results still fall in line with previous reports of about the prevalence of B. burgdorferi. 1.5% of all Texas ticks were positive for a Borrelia species, specifically B. lonestari. While this study was unable to identify the causative agent for STARI, 454 sequencing was able to provide a tremendous insight into the bacterial flora and possible pathogenic species of both the I. scapularis and the A. americanum tick.

Pulmonary hypoplasia and anasarca syndrome in Cika cattle

BACKGROUND: Hydrops foetalis is defined as excessive fluid accumulation within the foetal extravascular compartments and body cavities. It has been described in human and veterinary medicine, but despite several descriptive studies its aetiology is still not fully clarified. Pulmonary hypoplasia and anasarca (PHA) syndrome is a rare congenital abnormality in cattle that is characterised by hydrops foetalis including extreme subcutaneous oedema (anasarca) and undeveloped or poorly formed lungs (pulmonary hypoplasia). Until now, sporadic cases of PHA were reported in cattle breeds like Australian Dexter, Belted Galloway, Maine-Anjou, and Shorthorn. This report describes the first known cases of PHA syndrome in Slovenian Cika cattle. CASE PRESENTATION: A 13-year-old cow aborted a male calf in the seventh month of pregnancy, while a male calf was delivered by caesarean section on the due date from a 14-year-old cow. The pedigree analysis showed that the calves were sired by the same bull, the dams were paternal half-sisters and the second calf was the product of a dam-son mating. Gross lesions were similar in both cases and characterized by severe anasarca, hydrothorax, hydropericardium, ascites, hypoplastic lungs, absence of lymph nodes, and an enlarged heart. The first calf was also athymic. Histopathology of the second affected calf confirmed severe oedema of the subcutis and interstitium of the organs, and pulmonary hypoplasia. The lymph vessels in the subcutis and other organs were severely dilated. Histopathology of the second calf revealed also lack of bronchus associated lymphoid tissue and adrenal gland hypoplasia. CONCLUSIONS: The findings were consistent with known forms of the bovine PHA syndrome. This is the first report of the PHA syndrome occurring in the local endangered breed of Cika cattle. Observed inbreeding practice supports that this lethal defect most likely follows an autosomal recessive mode of inheritance. In the light of the disease phenotype it is assumed that a mutation causing an impaired development of lymph vessels is responsible for the hydrops foetalis associated malformations in bovine PHA.
