Feline renal allograft rupture
Authors: Palm Carrie A. , Aronson Lillian R. , Mayhew Philipp D. 
Published: March 2010

A 5-year-old domestic shorthair cat, that had undergone renal transplantation 3 months earlier, was evaluated after an acute episode of abdominal discomfort. Abdominal ultrasound revealed an enlarged renal allograft (5.5 cm; reference range, 3.2–4.2 cm) with pyelectasia (renal pelvis=3.7 mm; reference range, 1–2 mm). Based on the ultrasonographic appearance of the allograft, primary rule-outs for the renomegaly included hypertrophy and allograft rejection. The ureter and urethra were dilated and a mild amount of abdominal effusion was noted. Thirty-six hours after admission, the cat became acutely hemodynamically unstable and was diagnosed with a hemoabdomen. Review of the original ultrasound revealed a peri-renal hematoma. During emergency laparotomy, ruptures in the cortex of the transplanted kidney were found to be the source of hemorrhage. Immediately following surgery, the cat experienced cardiorespiratory arrest, and resuscitation was not successful. Necropsy and histopathology revealed rupture of the renal allograft. This is the first reported case of renal allograft rupture in a cat, whereas allograft rupture has been reported in human renal transplant patients.

Abstract
40Ar/39Ar dating yielded the reliable ages of andesite from the Unerikan complex (102.1 ± 1.4 Ma) and basaltic andesite from the Burunda complex (107.3 ± 2.4 Ma). The established age of volcanism is close to one of the stages of formation of the Khingan–Okhotsk volcanoplutonic belt. The petrography and geochemistry of basic, normal-basic, and normal rocks point to their dual character: They combine features specific for tholeiitic and calc-alkalic rocks. Most likely, these rocks formed in the setting of transform continental margin.
Paleomagnetism of Late Paleozoic, Mesozoic, and Cenozoic rocks in Mongolia
Authors: Kovalenko D.V. 
Published: March 2010

AbstractRock complexes in Mongolia experienced two remagnetization events. Almost all secondary remanence components of normal polarity were acquired apparently in the Cenozoic, after major deformation events, and those of reverse polarity were associated with intrusion of bimodal magmas during the Late Carboniferous–Permian reverse superchron. Active continental-margin sequences in some areas of Mongolia were folded prior to the Late Carboniferous–Permian magnetic event. The primary origin of magnetization in Late Paleozoic and Mesozoic rocks has been inferred to different degrees of reliability. According to paleolatitudes derived from most reliable paleomagnetic data, the analyzed rocks were located far north of the North China block throughout the Late Paleozoic and Early Mesozoic. Mongolia, as well as Siberia, moved from the south to the north in the Paleozoic, back from the north to the south between the latest Triassic and the latest Jurassic, and remained almost within the same latitudes in Cretaceous and Cenozoic time. These paleolatitudes show no statistical difference from those for the Siberian craton at least since the latest Permian (275–250 Ma). Older Mongolian complexes (with ages of 290, 316, and 330 Ma) likewise may have formed within the Siberian continent, which makes their paleomagnetic determinations applicable to calculate the polar wander path for Siberia. The paleolatitudes of Early Carboniferous sediments in Mongolia differ significantly from those of Siberia, either because of overprints from the reverse superchron or because they were deposited away from the Siberian margin.
Terpanes and steranes in coals of different genetic types in Siberia
Authors: Kashirtsev V.A. , Moskvin V.I. , Fomin A.N. , Chalaya O.N. 
Published: March 2010

Abstract
Chloroform extracts of coals from different genetic groups and different ages have been studied by chromato-mass-spectrometry, namely, Devonian liptobioliths from the Barzas region (Kuznetsk Basin) and Lower Cretaceous humites and sapropelites from the Kangalas and Taimylyr deposits, respectively (Lena Coal Basin). It has been established that the most ancient Devonian liptobioliths formed in coastal environments. Lipids of different biotas of marine and continental genesis, including resins of early Conifers, were the source of biomarker molecules. The Mesozoic humic and sapropelic coals differ little in chemofossil biomarkers, which might be related to their significant bacterial transformation and biosynthesis of chemofossils mainly by prokaryotes.
Divergence between Asian, European and Canadian populations of the monogenean Pseudodactylogyrus bini indicated by ribosomal DNA patterns

Published: March 2010

AbstractThe monogenean Pseudodactylogyrus bini parasitizes the gills of eels belonging to the genus Anguilla. Circumstantial evidence suggests that the parasite has been spread accidentally from the Pacific area (East Asia) to Europe by the intercontinental eel trade. This is based on early descriptions of the parasites from Asian regions and the lack of records of the parasites in Europe before 1977. In addition, the susceptibility of European eels to infections with the parasite is significantly higher compared to that of Japanese eels, which could indicate that the European eel had not undergone co-evolution with this parasite. The present study was undertaken to elucidate the origin of the parasite by using molecular tools. Parasite samples were obtained from Europe (Germany), Asia (Taiwan) and Nova Scotia, the latter of which is the first record of P. bini in Canada. Sequencing of rDNA comprising part of the internal transcribed spacer 1 (ITS1) gene, 5.8S and part of ITS2 (1323 bp) showed that P. bini isolates from the first two regions showed high variability. One sequence was found both in a number of Asian parasites and with one to a few transitions in European parasites, which could indicate that they were split recently into the two regions. Other sequence variations suggested that one or a few genotypes of P. bini were imported on one occasion from Asia to Europe and that the two geographic isolates subsequently developed differently in the two regions. The Nova Scotian/Canadian isolates showed no variation and were found to be unique compared to the European and Taiwanese forms, indicating that this population is independent in origin. This could indicate that the Canadian parasites were introduced to North America on another occasion and independently of the European colonization.
Wellbeing depends on social relationship characteristics: comparing different types and providers of support to older adults
Authors: MERZ EVA-MARIA , HUXHOLD OLIVER 
Published: March 2010

ABSTRACTThis paper examines the associations between different forms of support, who provides the support and the wellbeing of older adults in Germany. Particular attention is paid to the wellbeing differences associated with kin and non-kin providers and with emotional support and instrumental support. In addition, the quality of relationships with kin and non-kin is examined as a moderator of the association between social support and wellbeing. Data for 1,146 respondents to the German Ageing Survey in 2002 were analysed to determine the combinations of emotional or instrumental support, kin or non-kin providers and relationship quality that best predicted wellbeing. Emotional support from kin and instrumental support from non-kin were both found to associate positively with wellbeing. Emotional support from non-kin providers did not associate with wellbeing, whereas instrumental support from kin providers had a negative association with one aspect of wellbeing. Higher relationship quality, whether with kin or non-kin, positively related to wellbeing. Interestingly, the negative impact of instrumental kin support was qualified by relationship quality. In other words, for people with high-quality relationships, receiving instrumental support from kin did not decrease wellbeing. When the relationship with a family carer or supporter is characterised by high quality, the challenges of frailties in old age, such as decreasing capacities and an increasing need for social support, can be met without compromising wellbeing.
The burden of long-term care: how Italian family care-givers become employers
Authors: DEGIULI FRANCESCA 
Published: March 2010

ABSTRACTIn recent years in Italy, population ageing, rising female labour-market participation, and the restructuring of the welfare state have combined to create increased demand for long-term care services for frail and dependent older people. The rising demand has increasingly been met by immigrant women of different nationalities, and to a lesser extent immigrant men, who are hired to provide individualised care in people's own homes and other private settings. While there have been many studies of this growing phenomenon, very little attention has been paid to the reasons that bring family care-givers to choose this care-support option. To begin to fill the gap, this paper reports the finding of a qualitative study of 26 family members who were caring for a disabled elder. Semi-structured interviews lasting between 60 and 100 minutes and that covered various aspects of long-term care in family households were conducted. The participants' responses indicate that they did not choose immigrant home eldercare assistants solely for economic reasons but also to be consistent with cultural, moral and traditional understandings of family responsibilities and care. They also provide valuable findings and insights into Italian attitudes towards the welfare state and the care-labour market. While the wealthiest respondent declared a clear predilection for the free-market and a desire to bypass the state, the majority of the respondents advocated a stronger role of the welfare state in helping people cope with the increased burden of long-term care.
Filling a missing link: the influence of portrayals of older characters in television commercials on the memory performance of older adults

Published: March 2010

ABSTRACTThe portrayal of older characters in television commercials has over time become more varied and positive. This study examines how different portrayals of older characters relate to self-stereotyping, a process through which older individuals apply their beliefs about older people in general to themselves and behave accordingly. The study thereby seeks to connect, as few have previously done, cultural studies and critiques of media portrayals with psychological studies of the effects of self-stereotyping. Sixty participants aged 65–75 years were primed with television commercials that portrayed older characters in different ways: ‘warm and incompetent’, ‘warm and competent’, and ‘cold and competent’. It was hypothesised that priming with warm/incompetent portrayals would have a negative effect on memory performance because such representations match the dominant stereotype, and that the effect would occur only among older people who identify with their own age group. It was found that the participants who identified with their own age group did indeed show impaired memory performance after priming with warm/incompetent portrayals, but also that the same effect was found after priming with warm/competent portrayals. The findings are discussed in terms of resistance against stereotyping by older individuals themselves as well as by media producers.
Civil Service Reform in China: Impacts on Civil Servants' Behaviour
Authors: Burns John P. , Xiaoqi Wang 
Published: March 2010

AbstractChina's civil service reforms sought to improve the performance of civil servants by introducing more competitive selection processes, incentives to reward performance, and tightened monitoring and supervision. The impact of the reforms was undermined by clashes with other policies being implemented at the time and by a failure to address elements of organization culture that have rewarded various forms of illegal behaviour, such as corruption. Empirical material for our study is drawn from government data and the experience of civil service reform in three Chinese urban areas (Beijing's Haidian district, Changchun and Ningbo) since the 1990s.
Gauging the Elite Political Equilibrium in the CCP: A Quantitative Approach Using Biographical Data
Authors: Shih Victor , Shan Wei , Liu Mingxing 
Published: March 2010

AbstractCan one man dominate the Chinese Communist Party? This has been a much debated issue in the field of Chinese politics. Using a novel database that tracks the biographies of all Central Committee (CC) members from 1921 to 2007, we derive a measure of top CCP leaders' factional strength in the CC. We show that Mao could not maintain a commanding presence in the Party elite after the Eighth Party Congress in 1956, although the Party chairman enjoyed a prolonged period of consolidated support in the CC at a time when the CCP faced grave external threats. No Chinese leader, not even Mao himself, could regain the level of influence that he had enjoyed in the late 1940s. Our results, however, do not suggest that a “code of civility” has developed among Chinese leaders. The Cultural Revolution saw the destruction of Liu Shaoqi's faction. Although violent purges ended after the Cultural Revolution, Chinese leaders continued to promote followers into the CC and to remove rivals' followers.
Upper ocean layer dynamics and response to atmospheric forcing in the Terra Nova Bay polynya, Antarctica
Authors: Cappelletti Andrea , Picco Paola , Peluso Tiziana 
Published: March 2010

AbstractA one-year time series of Acoustic Doppler Current Profiler (ADCP) data was collected in Terra Nova Bay (TNB) polynya (Ross Sea, Antarctica) during 2000. Together with Automatic Weather Station (AWS) Eneide meteorological data and Special Sensor Microwave Imager (SSM/I) ice concentration data, ADCP data were analysed to investigate upper layer dynamics and variability due to atmospheric forcing. Empirical Orthogonal Function (EOF) analysis was performed to separate the surface variability caused by local forcing from the large-scale circulation component. In particular, the first mode represented the barotropic circulation while the second the stronger surface currents. The decrease in shelf water density from melting sea ice resulted in an off-shore density gradient producing a southern shift in the circulation. This result proved to be consistent with the in situ data acquired during February–April at 120 m depth. The observed variability of the surface currents was assessed with respect to the thermal wind equation and the steady Ekman model. Strong katabatic winds shifted the surface currents eastward with respect to the general north-eastern circulation. The wind stress acted as a relevant forcing for the surface large-scale circulation in TNB, but had negligible effects on the vertically integrated transport.
Barriers to increasing fruit and vegetable intakes in the older population of Northern Ireland: low levels of liking and low awareness of current recommendations

Published: March 2010

AbstractObjectiveTo investigate barriers to increasing fruit and vegetable (f + v) intakes in a large sample of the older population of Northern Ireland (NI), in relation to current intakes.DesignThe study was conducted using a telephone survey assessing f + v intakes, barriers to increasing intakes and various demographic and lifestyle characteristics. Barriers to increasing intakes were investigated using twenty-two closed-response items and one open-response item.SettingNI.SubjectsFour hundred and twenty-six older people from NI, representative of the older population of NI.ResultsPrincipal component analysis of the twenty-two closed-response items revealed five factors affecting f + v consumption. Significant associations with current intakes were found where greater f + v consumption was associated with greater ‘liking’ for f + v (B = 0·675, P < 0·01), greater ‘awareness of current recommendations’ for consumption (B = 0·197, P < 0·01) and greater ‘willingness to change’ (B = 0·281, P < 0·01). ‘Ease of consumption’ and ‘difficulties in achieving consumption’ were not associated with f + v intakes. Similar associations between f + v intakes and ‘liking’ and ‘awareness’ were also found in those consuming low intakes of f + v or those at risk of consuming low intakes. Low awareness and knowledge of recommendations were also found in response to the open-ended question in all groups, although some weight was also given here to environmental difficulties, such as cost and access.ConclusionsThese findings suggest that interventions aiming to increase f + v intakes in the older population of NI should focus predominantly on improving liking and improving knowledge and awareness of current recommendations.
Implications of the HIV-1 Rev dimer structure at 3.2 Å resolution for multimeric binding to the Rev response element

HIV-1 Rev is a small regulatory protein that mediates the nuclear export of viral mRNAs, an essential step in the HIV replication cycle. In this process Rev oligomerizes in association with a highly structured RNA motif, the Rev response element. Crystallographic studies of Rev have been hampered by the protein’s tendency to aggregate, but Rev has now been found to form a stable soluble equimolar complex with a specifically engineered monoclonal Fab fragment. We have determined the structure of this complex at 3.2 Å resolution. It reveals a molecular dimer of Rev, bound on either side by a Fab, where the ordered portion of each Rev monomer (residues 9–65) contains two coplanar α-helices arranged in hairpin fashion. Subunits dimerize through overlapping of the hairpin prongs. Mating of hydrophobic patches on the outer surface of the dimer is likely to promote higher order interactions, suggesting a model for Rev oligomerization onto the viral RNA.
Circadian control of XPA and excision repair of cisplatin-DNA damage by cryptochrome and HERC2 ubiquitin ligase

Published: March 2010

Cisplatin is one of the most commonly used anticancer drugs. It kills cancer cells by damaging their DNA, and hence cellular DNA repair capacity is an important determinant of its efficacy. Here, we investigated the repair of cisplatin-induced DNA damage in mouse liver and testis tissue extracts prepared at regular intervals over the course of a day. We find that the XPA protein, which plays an essential role in repair of cisplatin damage by nucleotide excision repair, exhibits circadian oscillation in the liver but not in testis. Consequently, removal of cisplatin adducts in liver extracts, but not in testis extracts, exhibits a circadian pattern with zenith at ∼5 pm and nadir at ∼5 am. Furthermore, we find that the circadian oscillation of XPA is achieved both by regulation of transcription by the core circadian clock proteins including cryptochrome and by regulation at the posttranslational level by the HERC2 ubiquitin ligase. These findings may be used as a guide for timing of cisplatin chemotherapy.

Published: March 2010

A total of 75 samples of two species of cyprinid fishes, Cyprinus carpio and Capoeta sp., were collected from three sections of the upper, middle and lower parts of the Kor River in the Fars province, and were analyzed for the determination of Pb, Hg, Cd and As concentrations by the Induction Coupled Plasma method. The average concentrations of Pb in muscle tissues of male Cyprinus carpio and Capoeta sp. were 0.77 ± 0.19, 0.41 ± 0.14 (mg kg− 1); while they were 1.03 ± 0.66, 0.42 ± 0.45 (mg kg− 1) for Hg, 0.08 ± 0.01, 0.08 ± 0.01(mg kg− 1) for Cd and 0.51 ± 0.06, 0.36 ± 0.11 (mg kg− 1) for As (Mean ± SE), respectively. In female Cyprinus carpio and Capoeta sp., the concentrations of Pb were 0.66 ± 0.20 and 0.41 ± 0.15 (mg kg− 1), Hg were 0.49 ± 0.45 and 0.32 ± 30 (mg kg− 1), Cd were 0.24 ± 0.01 and 0.26 ± 0.02 (mg kg− 1) and As were 0.39 ± 0.12 and 0.42 ± 0.13 (mg kg− 1), respectively. The concentrations of heavy metals in mid sampling zone were significantly (P &lt; 0.05) higher than the two other zones; while no significant differences (P &gt; 0.05) were seen in heavy metals assay between the two sexes and species.
The results showed industrial activities around the mid sampling zone of Kor River have polluted the River and the maximum concentrations of Pb, Hg and As residues in fish muscles were 1.46, 0.64 and 1.34 mg kg− 1, which are higher than the maximum levels allowed in fish filets by Environment Protection Agency (EPA) (2, 1 and 5 mg kg− 1), and are therefore not suitable for human consumption.
Freshwater fishes of Bangladesh: Fisheries, biodiversity and habitat
Authors: Hussain M.G. 
Published: March 2010

Fisheries play an important role in nutrition, income, employment and export earnings in Bangladesh. Fishes contribute to 63% of animal protein intake, about 5% of gross domestic product and 5% of export earnings; approximately 1.4 million people are directly engaged in fishing, 11 million in part-time fishing and another 3 million in aquaculture activities. The fisheries are highly diversified and comprised of inland open water capture fisheries, inland closed water culture fisheries and marine fisheries, which contribute respectively 35%, 44% and 21% to total fish production of 2.1 million tonnes. The major environmental factors having negative impacts on fisheries development are mainly: human impacts on riverine morphology, disruption of ecology, intensive agriculture, and modern developments. Fish conservation acts and regulations exist, but enforcement is difficult because of prevailing socio-economic conditions. Few regulatory mechanisms presently exist for protecting aquaculture environments.Production from inland openwater capture fisheries is declining due to over-exploitation and habitat degradation. However, aquaculture production, which mostly follows traditional practices, has been steadily increasing. Fisheries research has made significant contributions to the large growth of aquaculture through generating a number of economically viable, socially acceptable and environmentally compatible technologies being used by different categories of farmers, large and small. Presently, formulation and implementation of strategies and policies for conservation and sustainable management of degraded aquatic habitats have been immensely effective along with the generation and wider application/dissemination of suitable aquaculture and management technologies, which are expected to ensure the conservation of aquatic genetic resources. This paper reviews all these subjects and emphasizes future needs for development and implementation of policies/regulations at the national level, before it becomes too late to conserve valuable aquatic biodiversity and their habitats.
