Helminth fauna of sympatric Przewalski’s Equus przewalskii Poljakov, 1881 and domestic horses E. caballus L. in the Chernobyl exclusion zone, Ukraine
Authors: Slivinska K. , Dvojnos G. , Kopij G. 
Published: July 2006

Abstract
In 1998 Przewalski’s horses have been introduced in the Chernobyl exclusion zone (CEZ), N Ukraine. They live in the zone under natural conditions. No anthelminthic treatment to these introduced horses has been applied to date. In this same area, 19 domestic horses were also stabled by some peasants. Eighteen years after the Chernobyl nuclear disaster, and five years after this introduction, the diagnostic dehelminthisation method has been applied both to the Przewalski’s horses (n = 21) and the domestic horses (n = 6). In addition, in one Przewalski’s and one domestic horse helmith fauna was surveyed using the post-mortem method. A total of 29 and 19 helminth species has been recorded in the Przewalski’s and domestic horses respectively. Only six helminth species were common for the two horse species compared. Species from the family Strongylidae constituted the dominant helminth group. Four cyathostomine species (Cyathostomum catinatum; Cylicostephanus minutus, C. longibursatus, Cylicocyclus nassatus) formed the majority of helminth parasites both in the Przewalski’s and domestic horses. Our findings suggest that the CEZ has no effect on the species diversity of helminth fauna parasiting Przewalski’s horses, neither it has an effect on the prevalence and intensity of parasite infestation. Behavioural and ecological studies also support the lack of such effect.
Syncuaria squamata (Linstow, 1883) (Nematoda: Acuariidae) in the Great Cormorant [Phalacrocorax carbo sinensins (Blumenbach, 1798)] in northern Poland
Authors: Kanarek G. , Rolbiecki L. 
Published: July 2006

Abstract
Of the 105 great cormorants (Phalacrocorax carbo sinensins) from northern Poland (the Vistula Lagoon and Masurian Lake District), examined in 2000–2001, 67 proved hosts of the nematode Syncuaria squamata (Linstow, 1883). The prevalence, mean intensity, and intensity range amounted to 63.8 %, 36.2 specimens, and 1–120 specimens, respectively. The infection was heavier in the immature birds (84.6 %, 40.9 inds, and 1–120 inds) than in the adults (3.7 %, 1 ind.). The nematodes were dominated by gravid females (n=1846), followed by males (n=157), immature females (n=79), and L4 larvae (n=2). Measurements of the parasite are provided. S. squamata is a new species for the parasite fauna of Poland.
Xiphinema simile (Nematoda: Longidoridae) in the Czech Republic and a note on other Xiphinema species
Authors: Kumari S. 
Published: July 2006

Abstract
A nematode survey was carried out in South Moravia and Bohemia (Czech Republic) to assess the occurrence of Xiphinema in the rhizosphere of fruit orchards. Sixty six orchards in South Moravia and seven in Bohemia were studied during the years 2003 and 2004. Four Xiphinema species (X. diversicaudatum, X. pachtaicum, X. simile and X. vuittenezi) were recorded. X. simile constitutes a first record for the nematodes fauna of the Czech Republic.

Authors: Liu Y. , Hua J. , Jiang Y. , Li Q. , Wen D. 
Published: July 2006

Abstract
The distribution of nematode communities with depth in greenhouse soil of different ages from Shenyang suburb was investigated in October 2004. Thirteen families and 23 genera were observed in our study. Heterocephalobus was dominant genus in all treatments. The numbers of total nematodes and trophic groups declined with soil depth but increased with greenhouse age. Bacterivores were the most abundant trophic group in all treatments, followed by plant parasites and omnivores-predators, while fungivores were the least, only accounted for less than 4 % of the total abundance. Maturity index (MI) and plant parasite index (PPI) were effective in distinguishing differences in nematode community structure in different ages of greenhouses. The numbers of total nematodes were positively correlated with soil organic carbon, total nitrogen, nitrate, and electrolytic conductivity, but negatively with soil pH.
Enterobius vermicularis infection in preschool and schoolchildren of six rural communities from a semiarid region of Venezuela: A clinical and epidemiological study
Authors: Cazorla D. , Acosta M. , García E. , Garvett M. , Ruiz A. 
Published: July 2006

Abstract
Between August 2001 and July 2002, a cross-sectional survey was conducted to investigate clinical and epidemiological data on pinworm infection among 427 preschool and primary school age children of six rural communities from the semiarid region of Falcon state, northwestern Venezuela. Children were evaluated clinically and parasitologically by the Graham method. Overall prevalence was high (63.23 %). Pinworm infection rates were not significantly different between sex or age, suggesting similar transmission pattern and risk conditions for all individuals. Among the clinical findings and children’s habits, only perianal itching, enuresis, bruxism, and finger sucking showed significant higher percentages in infected children than in uninfected. Of interest was that anal pruritus (odds ratio [OR], 2.441), finger sucking (OR, 1.901), lower socioeconomic levels (OR, 4.358) and high levels of overcrowding conditions (≥ 3 persons/room: OR, 1.878; ≥ 2 persons/bed: OR, 11.833) appeared to be significant factors associated with transmission and endemic maintenance of enterobiasis among student children in this semi-arid Venezuelan region.

Authors: Borgsteede F. , Kavetska K. , Zoun P. 
Published: July 2006

Abstract
The presence of gizzard worms belonging to the genus Amidostomum was studied in birds in the Netherlands during the period 1975–2003. Amidostomum acutum was found in Anatidae: Anas acuta, A. clypeata, A. crecca, A. penelope, A. platyrynchos, A. strepera, Aythya ferina, Ay. fuligula, Ay. marila, Bucephala clangula, Melanitta fusca, M. nigra, Tadorna tadorna, Somateria mollissima and Recurvirostra avocetta. No Amidostomum species were found in the following three species of Mergini: Mergus albellus, M. merganser and M. serrator. Amidostomum anseris was seen in Anser albifrons, A. fabalis, Branta bernicla and Branta leucopsis. Amidostomum cygni was detected in Cygnus bewickii and Cygnus olor, while Amidostomum fulicae was found in Fulica atra. The prevalence is only given for bird species where ten or more individuals had been investigated: Anas platyrhynchos (n = 14): 21.4 %; Melanitta nigra (n = 12): 91.7 %; Somateria mollissima (n = 117): 100 %; Anser albifrons (n = 11): 100 % and Cygnus olor (n = 10): 60 %. Based on the present results, much more attention should be paid to the systematics, the epidemiological pattern and the pathogenicity of worms of this genus.

Authors: Háněl L. , Čerevková A. 
Published: July 2006

Abstract
Soil nematodes were studied in 11 meadow sites in the White Carpathians. In total, 155 species and 86 genera were found but the composition of nematode assemblages in eastern and western side of the mountains differed. Most nematode species belonged to the orders Tylenchida (52), Dorylaimida (35) and Rhabditida (16), and to the trophic groups bacterivores (47), plant parasites (29) and omnivores (25). In individual sites and sampling dates the number of species varied in range 18–68, genera 18–52, H’spp 1.32–3.50, H’gen 1.31–3.21, T 1.79–5.70, MI 2.32–3.63, PPI 2.03–2.98, and ΣMI 2.20–3.50. Composition of nematode assemblages and their matrix classification indicated a low degree of anthropogenous disturbance to the meadows.

Published: July 2006

Abstract
Nematode communities were used as bioindicators of changes in agroecosystems caused by anthropogenic factors. The aim of this study was to examine the impact of plowing and harrowing on nematode communities structure in comparison to “no tillage” treatments. The effects of mechanical disturbing of nematodes were determined on four soil treatments. Differences in nematode community structure were compared between two tillage regimes: standard tillage and no tillage. Research was conducted in 2000, in Kneževo near Osijek. Plowing had impact on increasing of bacterivorous nematodes and decreasing of fungivorous nematodes. Pratylenchus, Helicotylenchus and Tylenchus were dominant plant-feeding nematodes in no tillage treatments, while in plowing treatments Pratylenchus and Tylenchus were dominant. Abundance of Aphelenchoides decreased significantly after plowing. Tillage affected nematode communities in the soil ecosystem by changing the trophic structure and gave a decreasing, but not statistically significant, trend in MI.

AbstractBackgroundBiliary tract cancer (BTC) is a relatively rare malignancy worldwide. Little is known about potential etiologic contributions of occupational exposures.MethodsThe associations between occupational exposures to textile dusts and chemicals and BTC are investigated in a cohort of 267,400 women textile workers in Shanghai, China. A nested case‐cohort analysis of 162 BTC cases diagnosed during 1989–1998 was conducted with a reference subcohort of 3,188 workers. Exposures to workplace dusts and chemicals were reconstructed by linking complete work history data with a job‐exposure matrix (JEM). Hazard ratios (HR) and dose‐response trends were estimated by Cox proportional hazards modeling modified for case‐cohort design.ResultsAn elevated risk of ≥1‐year employment in maintenance jobs (HR 2.92, 95% CI: 1.48, 5.73) with a significant trend by duration is observed. Excess risk was also found for ≥20 years exposure to metals (HR 2.50, 95% CI: 1.09, 5.72).ConclusionsLong‐term exposure to maintenance work and metals in the textile industry may have increased BTC risk in this population.

Genetic disorders among Palestinian Arabs. 4: Genetic clinics in the community
Authors: Zlotogora Joël , Barges Saleh , Bisharat Bishara , Shalev Stavit A. 
Published: July 2006

AbstractGenetic disorders are frequent in the Arab population of Israel, mainly because of the preference for consanguineous marriages. Many of the inherited diseases are present with a high frequency only in a limited region or a single village. It is therefore not surprising that, in each of the villages, a different distribution of genetic diseases is found; thus, a detailed knowledge of the genetic disorders present in each village is of utmost importance for genetic counseling. As a direct consequence of these observations two community genetics clinics were opened as a pilot project to study their impact on the population to be served. The use of a computer database allowed for easier and more accurate genetic counseling. There were almost 1,500 visits in the 4‐year period since the introduction of the services. During the years an increase in the mean number of consultations per clinic as well as a change in the type of referrals was observed. There was an increasing proportion of clinics that were made at a time in which genetic counseling allow for primary prevention. The presence of a genetic counselor in the village clinic allows for better and closer contacts with the family physician. © 2006 Wiley‐Liss, Inc.

Published: July 2006

AbstractSeit der Veröffentlichung des letzten Aufsatzes im Jahre 1998 haben Übergangsmetallkomplexe des Bors anhaltendes Interesse ausgelöst. Borylkomplexe, die zahlenmäßig größte Klasse, wurden weiterhin intensiv erforscht, besonders in Hinblick auf die metallkatalysierte Funktionalisierung von organischen Substraten. Zusätzlich konnten neue Verbindungsarten wie Boran‐ und terminale Borylenkomplexe charakterisiert werden. Diese Studien erweiterten den Umfang der bekannten Koordinationstypen für borhaltige Liganden beträchtlich. Durch strukturanalytische und theoretische Untersuchungen konnten grundlegende elektronische Eigenschaften der Übergangsmetall‐Bor‐Bindung aufgeklärt werden, sodass sich Anwendungsmöglichkeiten für diese Komplexe abzeichnen. Hier werden die besten Methoden zur Bildung von Übergangsmetall‐Bor‐Bindungen vorgestellt, die zu neuen, faszinierenden Verbindungen geführt haben.
The transparency of the Universe limited by Lyα clouds
Authors: Schild R. E. , Dekker M. 
Published: July 2006

AbstractThe brightnesses of supernovae are commonly understood to indicate that cosmological expansion is accelerating due to dark energy. However the entire discussion presumes a perfectly transparent universe because no effects of reddening associated with the interstellar extinction law are seen. We note that with two kinds of dark matter (baryonic and nonbaryonic) strongly dominating the known mass of the universe, it is seriously premature to assume that these dark matter components have not reduced the transmission of the universe for cosmological sources.We show that the long‐known Lyα clouds, if nucleated by the population of baryonic dark matter primordial planetoids indicated by quasar microlensing, would act as spherical lenses and achromatically fade cosmologically distant sources. We attempt to estimate the amount of this cosmological fading, but ultimately the calculation is limited by lack of a satisfactory model for the tenuous outer parts of a primordial planetoid. We also consider the effects of such cosmological fading on the light of quasars. (© 2006 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

Published: July 2006

Abstract136 stars which were known to be members of the open cluster NGC 752 were observed at the R band with the ROTSE–IIId telescope located at the Turkish National Observatory (TUG) site. The data had been evaluated together with BV and 2MASS photometric data. A new practical method for separating dwarf and giant was described and applied. Evaluating the colour magnitude–diagrams with Padova isochrones revealed for the open cluster NGC 752 a metallicity similar to the Sun and an age of 1.41 ± 0.20 Gyr.

Concerning the instantaneous mass and the extent of an expanding universe
Authors: Fahr H. J. , Heyl M. 
Published: July 2006

AbstractIn this article we want to answer the cosmologically relevant question what, with some good semantic and physical reason, could be called the massM u of an infinitely extended, homogeneously matter‐filled and expanding universe. To answer this question we produce a space‐like sum of instantaneous cosmic energy depositions surrounding equally each spacepoint in the homogeneous universe. We calculate the added‐up instantaneous cosmic energy per volume around an arbitrary space point in the expanding universe. To carry out this sum we use as basic metrics an analogy to the inner Schwarzschild metric applied to stars, but this time applied to the spacepoint‐related universe. It is then shown that this leads to the added‐up proper energy within a sphere of a finite outer critical radius defining the point‐related infinity. As a surprise this radius turns out to be reciprocal to the square root of the prevailing average cosmic energy density. The equivalent mass of the universe can then also be calculated and, by the expression which is obtained here, shows a scaling with this critical radius of this universe, a virtue of the universe which was already often called for in earlier works by E. Mach, H. Thirring and F. Hoyle and others. This radius on the other hand can be shown to be nearly equal to the Schwarzschild radius of the so‐defined mass M u of the universe.

AbstractIn order to explore the characteristics of the environment surrounding Gamma‐Ray Bursts (GRBs), we have studied the correlation between the local density of galaxies and the presence of bursts. Using the Main Galaxy sample of the Sloan Digital Sky Survey Data Release 3 (SDSS DR3) and the Current BATSE GRB Catalog, we calculate the local surface density of galaxies within a radius of <2° surrounding each burst. It turns out that there is no correlation between the local density of galaxies and the presence of GRBs. (© 2006 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
Light curve and period study of V Trianguli
Authors: Gürol B. , Müyesseroğlu Z. , Özdemir T. 
Published: July 2006

AbstractNew BVR light curves and times of minimum light for the short period β Lyrae system V Tri were analyzed to derive the physical parameters of the system. The light curves were obtained at Ankara University Observatory and at the TÜBİTAK National Observatory during 5 nights in 2001 and 2002. A new ephemeris is determined for the times of primary minimum. The analysis of the light curves is made using the Wilson‐Devinney 2003 code. The present solution reveals that V Tri is a near‐contact system with a mass ratio near 0.5. The absolute radii and masses estimated for the components, based on our photometric solution, are R 1 = 1.94 R⊙, R 2 = 1.44 R⊙, M 1 = 2.68 M⊙, M 2 = 1.36 M⊙, respectively, for the primary and secondary components. The period variation of the system can be attributed to the light‐time effect. With the assumption of a coplanar orbit of the third body its revealed mass is m 3 = 0.17 M⊙.

Subclavian artery occlusion causing acute myocardial infarction in a patient with a left internal mammary artery graft
Authors: Barlis Peter , Brooks Mark , Hare David L. , Chan Robert K. 
Published: July 2006

AbstractAlthough atherosclerotic disease of the subclavian artery has previously been reported to cause coronary–subclavian steal syndrome, acute myocardial infarction because of occlusion of the subclavian artery in a graft‐dependent coronary circulation is an uncommon and previously unreported mode of clinical presentation. Increasingly, patients undergoing high‐risk cardiopulmonary procedures have comorbidities with extensive atherosclerotic disease of many vascular beds including coronary, cranial, and peripheral. Our discussion reviews the clinical presentation of such a case and highlights some of the important treatment options available when confronted with such a finding. The successful outcome achieved by percutaneous stenting of the subclavian artery and salvage of the graft may indicate that this modality is the initial treatment of choice in such cases. © 2006 Wiley‐Liss, Inc.

Published: July 2006

AbstractObjectives: To evaluate whether the maximum radiation dose to the patient's skin (MSD) can be estimated during percutaneous coronary intervention (PCI) procedures, we investigated the relationship between the MSD and fluoroscopic time, dose‐area product (DAP), and body weight, separately analyzing the relationships for different target vessels. Background: Many cases of skin injury caused by excessive radiation exposure during cardiac intervention procedures have been reported. However, real‐time maximum‐dose monitoring of the skin is unavailable for many cardiac intervention procedures. Methods: We studied 197 consecutive PCI procedures that involved a single target vessel and were conducted. The DAP was measured, and the MSD was calculated by a skin‐dose mapping software program (Caregraph). The target vessels of the PCI procedures were divided into four groups based on the AHA classification system: AHA 5–10, left anterior descending artery domain (LAD), AHA 11–15, left circumflex artery domain (LCx), AHA 1–3 = R 1–3, and AHA 4 = R 4. Results: The correlation coefficient (r) between the MSD and fluoroscopic time was higher for the right coronary artery (RCA) vessels (R 1–3, 0.852; R 4, 0.715) than for the left coronary artery (LCA) vessels (LAD, 0.527; LCx, 0.646), and the r value between the MSD and DAP was higher for the RCA vessels (R 1–3, 0.871; R 4, 0.898) than for the LCA vessels (LAD, 0.628; LCx, 0.694). Similarly, the correlation coefficient between the MSD and weight × fluoroscopic time (WFP) was higher for the RCA vessels (R 1–3, 0.874; R 4, 0.807) than for the LCA vessels (LAD, 0.551; LCx, 0.735). Conclusions: The DAP and WFP can be used to estimate the MSD during PCI in the RCA but not in the LCA, especially the LAD. © 2006 Wiley‐Liss, Inc.
Quantitative microsatellite analysis to delineate the commonly deleted region 1p22.3 in mantle cell lymphomas

AbstractThe molecular pathogenesis of mantle cell lymphomas (MCL), a subset of B‐cell non‐Hodgkin's lymphomas with a poor prognosis, is still poorly understood. In addition to the characteristic primary genetic alteration t(11;14)(q13;q32), several further genetic changes are present in most cases. One of the most frequent genomic imbalances is the deletion of 1p22.1–p31.1 observed in nearly one‐third of MCL cases. This might indicate the presence of tumor suppressor gene(s) in this critical region of deletion. Quantitative microsatellite analysis (QuMA) is a real‐time PCR‐based method to detect DNA copy number changes. Since QuMA has the resolving power to detect subtle genomic alterations, including homozygous deletions, this may help to identify candidate tumor suppressor genes from deleted regions. To gain more insight into the molecular pathogenesis of MCL, QuMA was performed on genomic DNA from 57 MCL cases. Eight microsatellite loci mapping to the chromosomal region 1p22.3 were analyzed. Losses were observed in 51 of the 57 (∼89.5%) samples. Two cases showed a homozygous deletion at the locus containing the gene SH3GLB1, which plays a key role in Bax‐mediated apoptosis. Two hotspots with copy number losses were detected at chromosomal localizations 85.4 and 86.6 Mb encompassing BCL10 and CLCA2. Both the genes seem to be attractive candidates to study tumor suppressor function in MCL.
