Abstract

Background: Environmental pollution is one of the most serious problems mankind is facing in this century. Arthropods and fish are highly sensitive to synthetic pyrethroids. In this article, we describe the acute toxicity, free amino acid level and protease activity in the tissues of freshwater fish when exposed to cypermethrin.

Methods: Acute toxicity of cypermethrin to the freshwater fish Tilapia mossambica was studied using a static bioassay method. The effect of cypermethrin on free amino acid and protease activity in tissues of gills, liver and muscle of freshwater fish Tilapia mossambica was also studied.

Results: The LC50 in 96 h was found to be 35.6 μg/L. Free amino acid levels and protease activity showed an elevation following exposure to lethal and sub lethal doses of cypermethrin. A significant change was noticed on day 4 increase. However, normal condition was restored only in sub lethal concentration.

Conclusions: The present study clearly shows significant changes in the Tilapia mossambica when exposed to a low quantity of cypermethrin.

Zusammenfassung
In jüngster Zeit wurden mehrere Autoantikörper neu identifiziert, die eng mit verschiedenen Formen der Autoimmun-Enzephalitis assoziiert sind. Die Antikörper richten sich gegen Strukturen der Zelloberfläche von Neuronen: Glutamat-Rezeptoren (Typen NMDA und AMPA), GABAB-Rezeptoren sowie die Kaliumkanal(VGKC)-assoziierten Proteine LGI1 und CASPR2. Sie sind doppelt so häufig wie die klassischen paraneoplastischen Antikörper (Anti-Hu, -Yo, -Ri, -Ma, -CV2, -Amphiphysin), weniger eng mit einem Tumor assoziiert und die korrespondierenden klinischen Syndrome sprechen deutlich besser auf eine Immuntherapie an. Der monospezifische Nachweis dieser Autoantikörper in Serum oder Liquor der Patienten erfolgt vorwiegend durch indirekte Immunfluoreszenz, unter Verwendung transfizierter HEK293-Zellen, welche die Membran-assoziierten Zielantigene rekombinant exprimieren. Aufgrund symptomatischer Überlappungen der verschiedenen Krankheitsentitäten ist es sinnvoll, alle diese Parameter bei jedem Patienten parallel zu bestimmen (Autoantikörper-Profile). Eine rasche Diagnosestellung (maßgeblich unterstützt durch das serologische Labor), der unmittelbare Beginn immuntherapeutischer Intervention und, im Falle einer paraneoplastischen Ätiologie, die Entfernung des Tumors entscheiden die Prognose. Nach eigenen Untersuchungen findet man bei den neu identifizierten Autoimmun-Enzephalitis-Formen Antikörper gegen Glutamat-Rezeptoren (Typ NMDA) mit 42% am häufigsten. Ein Drittel der positiven Reaktionen wurde in der Laborpraxis durch einen Autoantikörper verursacht, dessen Bestimmung vom Kliniker nicht angefordert war: Das unterstreicht die Notwendigkeit, für diesen Diagnostik-Bereich wegen der gebotenen Eile multiparametrische serologische Testsysteme einzusetzen.
Strain localization in polycarbonates deformed at high strain rates

Published: October 2011

Abstract
We studied three-dimensional transient large coupled thermomechanical deformations of a polycarbonate (PC) plate with a through-the-thickness inhomogeneity at its centroid. The PC exhibits strain softening followed by strain hardening and its elastic moduli are taken to be functions of strain rate and temperature. The inhomogeneity is either a void or a region of initial temperature higher than that of the rest of the plate. The nonlinear initial-boundary-value problem is solved numerically by the finite element method. It is found that deformations localize into narrow regions that we call bands. For a plate deformed in tension, the maximum principal stretch within the band is almost twice that of the maximum shear strain and for a plate deformed in shear the two have approximately the same magnitude. For the PC deformed in uniaxial compression, we call the minimum slope of the effective stress vs. the effective strain curve in the strain softening regime as the softening modulus, E

s
, and find values of E

s
and the defect strength needed for the deformations to localize. These values are found to be different for the plate deformed in shear from that deformed in tension and the minimum value of E

s
for the localization of deformation also depends upon the defect type and the defect strength (e.g., the ratio of the major to the minor axes of the elliptic void).

Objectives Cleft palate is a common congenital maxillofacial defect. We wish to present the fabrication of a modified feeding plate that will adapt to the changing palatal and velopharyngeal morphology during function. Case Report A neonate with unilateral cleft lip and palate was referred to our clinic for the fabrication of a feeding plate. Intraoral examination revealed a cleft involving the uvula and the soft palate, with an alveolar defect on the left side. An impression was taken and a dental cast was obtained. A 1-mm Bioplast clear soft plate was pressed on the model. After trimming the edges of the plate, several retentive holes were made for its attachment to the hard plate. With the Bioplast soft plate replaced on the cast, plaster was used to cover parts of the soft plate that were not to come in contact with the hard plate. Biocryl resin was put on the retentive holes and 2-mm Biocryl C Rosa-transparent plate was pressed. The edges of the plate were cut, trimmed, and polished. Conclusion This modified feeding plate effectively obstructed the soft palate defect. The adaptation of the flexible bulb of the appliance with the soft palate was excellent. Evaluation with nasoendoscopy revealed the synchronized movement of the bulb of the appliance with the soft palate during swallowing. Soft extension of the feeding plate eliminated the risk of irritation, and the baby accepted the appliance easily.

Abstract
52-years old man years following the kidney transplantation from deceased donor was admitted to the hospital with fever and progressive abdominal pain. The patient was diagnosed with chronic hepatitis C seven years before admission. Graft function in posttransplant period was stable and optimal, the patient was treated with standard maintenance immunosupresive protocol (cyclosporine A, mycophenolate mofetil and low-dose prednison), metylprednisolon bolus therapy (1 g/m2 body surface area), was administered two months prior to admission due to creeping creatinine (suspection of acute rejection was not confirmed by biopsy). Empiric antibiotic treatment due to febrile status was ineffective. Abdominal ultrasound and computer tomography (CT) scan revealed three tumorous lesions in the liver, radical surgical intervention was not executable. Histological examination of the tissue from the lesions demostrated alveolar echinococcosis, serology for Echinoccocus multilocularis was positive. Long-term treatment by mebendazol 200 mg twice daily led to disappearance of the clinical symptoms, but after the therapy cessasion patient was again hospitalized with fever and progression of cystic lesions in CT scan. Following the mebendazol therapy reinstalation the clinical course of echinococcosis was improved and remained stable, transplant kidney failure occurred due to progression of interstitial fibrosis/tubular atrophy and chronic haemodialysis was initiated one year later.

Abstract
Concentrations of various essential and toxic elements (Zn, Mn, Fe, Cu and Cd) were analysed by inductively coupled plasma optical emission spectrometry (ICP-OES) in the sheep tapeworm (Moniezia expansa) and in different tissues of its host Ovis aries. The element concentrations of the cestode parasites were compared to different organs (liver, kidney, and muscle) of sheep that were exposed to experimental amounts of Cd (0.2 g of CdCl2 added to 10 ml of distilled water and administered orally to the sheep every day for a period of 1 week). All sheep were randomly divided into four groups; the first group (Cd) contained uninfected, Cd exposed sheep, and its control (group C) were uninfected and unexposed to Cd; the second group (TCd) contained infected, Cd exposed sheep, and its control (group CT) contained infected, unexposed sheep. The experimental Cd exposure resulted in significantly higher Mn concentrations in sheep tapeworms (10.0 mg/kg) than in sheep muscle (0.6 mg/kg) and kidney (0.8 mg/kg). The experimental Cd exposure also significantly decreased the Cu concentrations in sheep liver and muscle. Moreover Cd exposure decreased the Fe concentrations in sheep kidney but caused it to increase in sheep liver and muscle. Zinc concentrations showed no differences between groups (Cd, TCd, C, T) in any monitored sheep tissues. The article also discuss the effect of tapeworm infection on a significant decrease of Fe in sheep muscle, liver and kidneys, as well as a decrease in Cu levels of the muscles and liver. This mineral imbalance may contribute to various health problems such as osteoporosis, metabolic processes disorder, antioxidant (SOD) dysfunction etc.

Abstract
Parasitic infection during pregnancy represents a serious stress factor and affects the course of pregnancy and the foeto-maternal relationship. The infection may not clinically manifest itself, however it can modulate the immune response of the offspring for a long-time. The influence of secondary Echinococcus multilocularis infection on the proportion of CD4+ and CD8+ T cells and the level of anti-Echinococcus antibodies were studied in Balb/c mice. The female mice were infected with homogenised metacestode material containing 2000 E. multilocularis protoscoleces (Group 1, 2). Group 1 was fertilised on day 60 post infection, while Group 2 remained unfertilised. Group 3 was uninfected and fertilised on the same day as Group 1. The numbers of both T cell subpopulations were higher in non-pregnant than in pregnant mice. In late pregnancy, the decline of CD4+, however, the increase of CD8+ T-cell subtypes were observed in both, infected and uninfected mothers, respectively. The strong humoral response with the high production of IgM and IgG2b antibodies in infected mice was detected. In infected mothers, IgG2b level was higher than in infected nonpregnant mice during almost whole monitored period. In Group 1, delivery caused suppression of Th2 immune response, represented by IgG1, under the level observed in uninfected mothers. The findings show the changes in helper regulatory and cytotoxic immunity mechanisms of infected mothers. In offspring of infected mothers all IgG subclasses were detected, however specific IgM were not transmitted neither transplacentary, nor transmammary.

Abstract
Parasitic infection during pregnancy can affect the course of pregnancy, complicate the foeto-maternal relationship and increase abortion rate. The work was aimed to study the course of E. multilocularis secondary infection and reproductive parameters in infected mice. The Balb/c mice were bred in the exponential phase of the metacestode growth, after infection with two different doses (0.5 ml or 1.25 ml) of metacestode material. In comparison to uninfected control group, the effect of infection on reproductive parameters (natality, size of litters) and the course of disease during pregnancy and after the delivery were monitored. The weight of E. multilocularis larval stages was higher in both fertilised groups in comparison to unfertilised control. The number of deliveries and litter counts were similar in both, infected and uninfected mice. Present study confirmed only minor impact of alveolar echinococcosis on the reproduction of rodents, intermediate hosts of parasite.
A new species of Parastrigea (Digenea, Strigeidae) endoparasite of Buteogallus urubitinga (Aves, Accipitridae) from Argentina
Authors: Drago F. , Lunaschi L. 
Published: October 2011

Abstract
A new strigeid digenean, Parastrigea macrobursa n. sp., is described from specimens recovered from the small intestine of the great black-hawk, Buteogallus urubitinga (Aves: Accipitridae), from Formosa Province, Argentina. The new species is characterized by having a tulip-shaped forebody, a hindbody without neck region, a large, well delimited copulatory bursa, and a very deep genital atrium. Three species of Parastrigea share the shape of the copulatory bursa namely P. faini, P. astridae and P. tulipoides. Parastrigea faini and P. astridae differ mainly from the new species by having the forebody strongly divided in two regions and very developed lateral expansions, and Parastrigea tulipoides by having a long neck region and a longer body size. This new species represents the first record of a member of the genus Parastrigea Szidat, 1928 parasitizing birds from Argentina. A key is presented for the species currently recognized as valid in the genus.

Abstract
A new nematode species, Raphidascaris (Ichthyascaris) arii sp. n. (Anisakidae), is described from male and female specimens found in the intestine of two species of marine siluriform fishes, the spotted catfish Arius maculatus (Thunberg) (Ariidae) (type host) and the striped eel catfish Plotosus lineatus (Thunberg) (Plotosidae) from the coastal region of the Gulf of Thailand, Thailand. Based on light and scanning electron microscopy examinations, the new species differs from other nine representatives of the subgenus Ichthyascaris Wu, 1949 mainly in the length of spicules (210–333 μm), body length of gravid females (10–17 mm), and in the presence of small cuticular spines or protuberances on the tail tip of both sexes and 21–30 pairs of preanal and 8 pairs of postanal papillae in the male. This is the first species of this subgenus reported from fishes of the order Siluriformes and the first species of the subgenus Ichthyascaris Wu, 1949 recorded from the Gulf of Thailand.
Resurrection of Pomphorhynchus tereticollis (Rudolphi, 1809) (Acanthocephala: Pomphorhynchidae) based on new morphological and molecular data
Authors: Špakulová M. , Perrot-Minnot M. , Neuhaus B. 
Published: October 2011

Abstract
Pomphorhynchus tereticollis (Rudolphi, 1809) is here redescribed on the basis of Rudolphi’s material, deposited in the Museum für Naturkunde Berlin, and on acanthocephalans recently collected from the type host Platichthys flessus (L.) and the region embodying the type locality. Out of the paratypes of P. tereticollis, the lectotype and paralectotypes have been designated. Their morphology fits well with that of newly collected material of P. tereticollis dissected from the type fish host from the Baltic coast near Stralsund. The resurrection of P. tereticollis, previously considered a synonym of Pomphorhynchus laevis (Zoega in Müller, 1779), is supported by several morphological features distinguishing the two Pomphorhynchus species: 1. The basal parts of the proboscis hooks located on the posterior proboscis half possess proximal projections in P. tereticollis but not in P. laevis. This shape of the hook bases is clearly visible only in unfixed fresh worms; 2. The last hooks are situated at the anterior part of the bulbus or rarely at the posterior-most end of the proboscis in P. tereticollis, while they lie anterior to the end of the proboscis in P. laevis; 3. The proboscis hooks No. 5 or 6 are markedly stout (robust) and clearly distinct in comparison with the surrounding hooks in P. tereticollis, while less robust and more similar to the hooks in P. laevis. In addition, genetic divergence between P. tereticollis and P. laevis based on ITS1, ITS2 and COI sequencing supports the existence of two distinct species and reveals that some isolates previously identified as P. laevis were actually P. tereticollis. Previous and present morphological and genetic data show that both Pomphorhynchus species occur in freshwaters throughout Europe and may infect the same fish hosts, such as chub and barbel, and also several species of isopods (Gammaridae). This study also provides morphological evidence that Pomphorhynchus intermedius Engelbrecht, 1957 is a synonym of P. tereticollis, because the only discrimination character of the former species, the “existing but small proximal projections of basal parts of the proboscis hooks located on the posterior proboscis half” are present also in P. tereticollis.

Abstract
Suppressiveness of soil amendments with different rates of composted biowaste materials, olive pomace, municipal green wastes, sewage sludge and spent mushroom substrate, was evaluated against the root-knot nematode Meloidogyne incognita on tomato in potting mixtures. Soil amendments were applied at 0, 10, 25, 50 and 100 g kg−1 soil, according to a randomized block design with five replications for each treatment. Sixty days after tomato transplanting, nematode population density on plant roots and in soil and root gall infestation were assessed on each root system, and plant top and root weight were also recorded. Soil pH, dry and organic matter content, total and ammoniacal nitrogen were analyzed at the same time. Olive pomace-based composts resulted in the highest nematode suppression (73–97 %, according to the rate) and significantly reduced gall formation on tomato roots. Olive-waste compost affected positively tomato growth only in combination with sheep wool wastes, but it caused phytotoxicity when mixed with chicken manure and urea. Soil amendments with composted mushroom substrate also provided a consistent nematode suppression and a significant increase of plant growth, whereas composted municipal green wastes were more suppressive and positively affected tomato growth when combined with sewage sludge. Soil chemical parameters were scarcely affected by compost amendments, as organic matter was significantly increased only by the olive pomace-derived composts and nitrogen content only at the highest rate of the five composts. Data from the experiment confirmed the potential of compost amendments for sustainable management of root-knot nematodes both in field and greenhouse container media, though their technical effectiveness and economic convenience are strictly dependent on a correct proportion and local availability of raw materials used in the composting process.

SCOPE for Research: Mental Health Consumers' Priorities for Research Compared with Recent Research in Australia
Authors: Banfield Michelle A. , Griffiths Kathleen M. , Christensen Helen M. , Barney Lisa J. 
Published: October 2011

Objective: The aim of this study was to identify consumer priorities for research on depression and bipolar disorder in Australia. Method: Australian consumers with personal experience of depression or bipolar disorder were surveyed online about research priorities for their condition using a questionnaire developed from an earlier qualitative phase of the SCOPE for Research project. Participants were asked to rate the importance of a number of broad research areas, specific research topics, target groups and settings in which to conduct research. These ratings were then compared to the content of relevant Australian research published between 1997 and 2006. Results: Consumers rated research into the management and treatment of depression and bipolar disorder of highest priority. Further, consumers rated those at risk of a mood disorder as the most important target groups for research and prioritized research conducted in health settings such as community mental health services ahead of research in other settings. There was some concordance between consumers' ratings of the broad topic areas and settings in which to conduct research and the amount of published research on these topic areas and settings. However, there was little published research on the highest ranked consumer-rated specific topics and target groups for research. Conclusions: Overall, there were substantial differences between the priorities of consumers and the recent research output, suggesting gaps in the Australian research base on mood disorders. The results of this study should be used to inform future research to ensure that it is guided by the priorities of the ultimate beneficiaries of the research, mental health consumers.
Assessing the summer water budget of a moulin basin in the Sermeq Avannarleq ablation region, Greenland ice sheet

Published: October 2011

AbstractWe provide an assessment of the supraglacial water budget of a moulin basin on the western margin of the Greenland ice sheet for 15 days in August 2009. Meltwater production, the dominant input term to the 1.14 ± 0.06 km2 basin, was determined from in situ ablation measurements. The dominant water-output terms from the basin, accounting for 52% and 48% of output, respectively, were moulin discharge and drainage into crevasses. Moulin discharge exhibits large diurnal variability (0.017–0.54 m3 s−1) with a distinct late-afternoon peak at 16:45 local time. This lags peak meltwater production by ∼2.8 ± 4.2 hours. An Extreme Ice Survey time-lapse photography sequence complements the observations of moulin discharge. We infer, from in situ observations of moulin geometry, previously published borehole water heights and estimates of the temporal lag between meltwater production and observed local ice surface uplift (‘jacking’), that the transfer of surface meltwater to the englacial water table via moulins is nearly instantaneous (<30 min). We employ a simple crevasse mass-balance model to demonstrate that crevasse drainage could significantly dampen the surface meltwater fluctuations reaching the englacial system in comparison to moulin discharge. Thus, unlike crevasses, moulins propagate meltwater pulses to the englacial system that are capable of overwhelming subglacial transmission capacity, resulting in enhanced basal sliding.
