The Acute Phase Protein Ceruloplasmin as a Non-Invasive Marker of Pseudopregnancy, Pregnancy, and Pregnancy Loss in the Giant Panda

After ovulation, non-pregnant female giant pandas experience pseudopregnancy. During pseudopregnancy, non-pregnant females exhibit physiological and behavioral changes similar to pregnancy. Monitoring hormonal patterns that are usually different in pregnant mammals are not effective at determining pregnancy status in many animals that undergo pseudopregnancy, including the giant panda. Therefore, a physiological test to distinguish between pregnancy and pseudopregnancy in pandas has eluded scientists for decades. We examined other potential markers of pregnancy and found that activity of the acute phase protein ceruloplasmin increases in urine of giant pandas in response to pregnancy. Results indicate that in term pregnancies, levels of active urinary ceruloplasmin were elevated the first week of pregnancy and remain elevated until 20–24 days prior to parturition, while no increase was observed during the luteal phase in known pseudopregnancies. Active ceruloplasmin also increased during ultrasound-confirmed lost pregnancies; however, the pattern was different compared to term pregnancies, particularly during the late luteal phase. In four out of the five additional reproductive cycles included in the current study where females were bred but no birth occurred, active ceruloplasmin in urine increased during the luteal phase. Similar to the known lost pregnancies, the temporal pattern of change in urinary ceruloplasmin during the luteal phase deviated from the term pregnancies suggesting that these cycles may have also been lost pregnancies. Among giant pandas in captivity, it has been presumed that there is a high rate of pregnancy loss and our results are the first to provide evidence supporting this notion

First case of Anaplasma platys infection in a dog from Croatia

<p>Abstract</p> <p>Background</p> <p>It is known that <it>Anaplasma (A.) platys</it>, the causative agent of infectious canine cyclic thrombocytopenia, is endemic in countries of the Mediterranean basin. However, few reports are available from the Balkans. This case report describes a dog, which was imported from Croatia to Germany in May 2010. One month later the dog was presented to a local veterinarian in Germany due to intermittent/recurrent diarrhoea. Diagnostic tests were performed to identify infections caused by <it>Anaplasma </it>spp., <it>Ehrlichia </it>spp., <it>Hepatozoon canis, Babesia </it>spp., <it>Leishmania </it>spp., <it>Borrelia burgdorferi </it>and/or <it>Dirofilaria immitis</it>.</p> <p>Findings</p> <p>Haematological examination of a blood smear revealed basophilic inclusions in thrombocytes, which were confirmed as <it>A. platys </it>with a species-specific real-time PCR. Additionally, an infection with <it>Babesia (B.) vogeli </it>was also detected (PCR and serology). No specific antibodies against <it>Anaplasma </it>antigen were detectable. Although the dog showed no specific clinical signs, thrombocytopenia, anaemia and elevated C-reactive protein (CRP) were observed. Sequencing of a 1,348-bp partial ribosomal RNA gene revealed highest homology to <it>A. platys </it>sequences from Thailand, Japan and France.</p> <p>Conclusions</p> <p><it>A. platys </it>was detected for first time in a dog imported from Croatia. As the dog was also co-infected by <it>B. vogeli</it>, unique serological and haematological findings were recorded. Thrombocytopenia, anaemia and elevated values of C-reactive protein were the laboratory test abnormalities observed in this case. <it>A. platys </it>infections should be considered in dogs coming from Croatia and adjacent regions.</p

Effect of Mannheimia (Pasteurella) haemolytica infection on acute-phase proteins and some mineral levels in colostrum-breast milk-fed or colostrum-breast milk-deprived sheep

The aim of this study was to investigate the levels of acute-phase proteins and minerals as indicators for the reactivity in 1-year-old sheep. A total of 26 Chios breed sheep were fed colostrum-breast milk (control, n = 15)or were deprived after separation from their mother immediately after birth(experimental, n = 11). Mannheimia (Pasteurella) haemolytica serotype A1 was inoculated intratracheally and blood samples were taken in vacuumed sera on days 0, 1, 4, 7, 10, 13, 16, 19 and 22. Antibiotic treatment was initiated after blood sampling on day 22, and blood samples were taken on days 1, 4 and 7 after the treatment. The levels of C-reactive protein (CRP), haptoglobin, ceruloplasmin, fibrinogen, zinc, iron and calcium, which are the indicators of immune function and infectious diseases were analysed. No significant difference between the control and trial groups before and after the infection was determined. However, serum CRP, haptoglobin, ceruloplasmin and fibrinogen levels were increased in the course of the infection. These levels were restored to normal following treatment

Integrating multicriteria evaluation and data visualization as a problem structuring approach to support territorial transformation projects

Large freight or passenger transport projects are problematic and controversial because many financial, technical, environmental and social aspects need to be considered. Indeed, the interface between the transport project and territorial planning domains is generally the focus of considerable heated debates, which often develop into conflicting decision contexts characterized by a high level of complexity. This paper presents a possible response to these difficulties through an innovative approach that integrates the analytic network process and the interactive visualization tool. The approach is intended to be deployed as problem structuring method, with a view to creating a common language for the actors involved and a shared basis for generating fruitful discussions. The proposed approach was applied in the context of the German section of the Genoa–Rotterdam railway corridor within the Interreg IVB NWE Project ‘‘Code24’’. The reported application shows how the combination of visualization and real-time interaction with spatial data provided effective decision support to a multinational stakeholder group. More generally, the application presented in this paper aims to demonstrate the potential of the approach for the selection of a transport improvement strategy within the content of territorial transformation
