Published: January 2009

The research work was conducted to find out the seasonal prevalence of ectoparasites of carp fingerlings. Seven species of parasites viz. Trichodina domerguei, Trichodina reticulata, Chilodonella cyprini, Myxobolus koi, Dactylogyroides tripathi, Dactylogyrus extensus and Dactylogyrus catlarius were recovered from 640 fingerlings of Silver carp (Hypophthalmicthys molitrix), Bighead carp (Ctenopharyngodon idella), Common carp (Cyprinus carpio), Thai punti (Puntius gonionotus), Catla (Catla catla), Rui (Labeo rohita) and Mrigal (Cirrhina mrigala) from different nursery ponds of Bogra district during June 2005 to May 2006. The highest prevalence (95%) was in Trichodina domerguei and lowest (10%) in Dactylogyrus catlarius during winter season. Average prevalence of protozoan and monogenean parasite was 37.16 in rainy season, 40.08 in winter season and 30.25 in summer season. Winter is the most disease occurring season of the year.

Published: January 2009

A trial was conducted to evaluate the effects of combination of soybean meal (SBN), mustard oilcake (MOC), sesame oilcake (SOC) and linseed oilcake (LOC) as alternative for dietary fish meal (FM) protein for Labeo rohita fingerling for a period of 56 days. Six experimental diets were formulated by replacing 30, 50, 60, 70 and 100% (2 diets) of the total dietary fish meal protein by the combination of FM, SBM, MOC, SOC, and LOC. The combinations of the protein sources were as diet 1 (FM 100%), diet 2 (FM:SBM:MOC::70:15:15), diet 3 (FM:SBM:SOC:LOC::50:20:20:10), diet 4 (FM:SBM:SOC:LOC::40:20:20:20), diet 5 (FM:SBM:SOC:LOC::25:30:15:30), diet 6 (SBM:MOC:SOC:LOC::25:25:25:25) and diet 7 (SBM:SOC:LOC::40:30:30). The performances of these six test diets were compared with the diet 1 (control). All diets were iso-nitrogenous containing about 30% protein. The growth trial was conducted in a flow through system under laboratory condition with three replications for each treatment. On the basis of the growth response, food conversion ratio (FCR), protein efficiency ratio (PER) diet 7 showed better performance followed by diet 1, diet 2, diet 5, diet 3, diet 4 and diet 6 respectively but those were not significantly different (P>0.05). The diet 6 produced the lowest performance. The apparent protein digestibility (APD) values for all the experimental diets were very nearer but significantly different (P0.05) in diets even from control one which were formulated to evaluate the effects of combination of low cost oil seed cakes as dietary protein source for Labeo rohita fingerling. Hence, it might be concluded that from the economic point of view, that all the low cost oil seed cakes which are locally available can be used in combination form as the alternative protein source for the feed of Labeo rohita.

A study on the abundance of zooplankton of a culture and a non-culture pond of the Rajshahi University campus
Authors: Rahman Sharmeen , Hussain M Afzal 
Published: January 2009

Zooplankton constitute important food item of many omnivorous and carnivorous fishes. The study was conducted with an aim to study the zooplankton production including physico-chemical parameters with an emphasis to the existing management practices taken by the operators. The study was carried out in a culture and a non-culture pond of Rajshahi University campus was carried out from September, 2004 to February, 2005. Monthly fluctuations of some physico-chemical parameters were noted. The ponds showed alkaline in nature with moderate bicarbonate alkalinity. Diurnal change of water temperature, free CO2 and dissolved Oxygen were also studied. Four groups of zooplankton were identified, of which copepods (1260 units/l and 973.33 units/l in pond-1 and pond-2 respectively) were most dominant. A total of 9 genera of zooplankton were identified of which Cyclops (68.25% and 60.28% of total copepods) was most abundant in both ponds. Total zooplankton showed positive correlation with pH, carbonate alkalinity (CO3) and bicarbonate alkalinity (HCO3) in both ponds and DO, carbon dioxide (CO2) in pond-1. Present findings indicated that the culture pond showed better result than that of the non-culture pond regarding zooplankton production.

Desensitization to media violence over a short period of time
Authors: Fanti Kostas A. , Vanman Eric , Henrich Christopher C. , Avraamides Marios N. 
Published: January 2009

AbstractThis study investigated the desensitization to violence over a short period of time. Participants watched nine violent movie scenes and nine comedy scenes, and reported whether they enjoyed the violent or comedy scenes and whether they felt sympathetic toward the victim of violence. Using latent growth modeling, analyses were carried out to investigate how participants responded to the different scenes across time. The findings of this study suggested that repeated exposure to media violence reduces the psychological impact of media violence in the short term, therefore desensitizing viewers to media violence. As a result, viewers tended to feel less sympathetic toward the victims of violence and actually enjoy more the violence portrayed in the media. Additionally, desensitization to media violence was better represented by a curvilinear pattern, whereas desensitization to comedy scenes was better represented by a linear pattern. Finally, trait aggression was not related to the pattern of change over time, although significant effects were found for initial reports of enjoyment and sympathy. Aggr.

Published: January 2009

AbstractThis stone lantern is known as the “Koto‐ji”, or “harp‐tuner”, as it resembles the tuning bridge of the Japanese koto. The six windows of the lantern are said to symbolize the six essential attributes of a perfect garden, such as the one it overlooks: spaciousness, seclusion, artifice, antiquity, abundant water, and broad views. R. Hoffmann et al. report on two synthesized compounds containing the unusual S42− rectangles bound to either Ir or Rh fragments, illuminated by the two lamp windows. Like the Koto‐ji lantern, this paper, which suggests the presence of SS half‐bonds, sheds some light in the garden of beautiful compounds.

Published: January 2009

AbstractThe purpose of this study was to determine renal arterial anatomy and gender differences in adults without renovascular disease using multidetector computed tomography angiography (MDCTA). MDCTA datasets of 399 patients were retrospectively reviewed. Measurements of the aortorenal diameters, the angulation of the renal ostia and pedicles as well as the distance between the origins of the renal arteries were measured. Differences in measurements between genders were tested for statistical significance using analysis of variance (ANOVA) and Pearson's Chi‐Square tests. A total of 798 renal arteries were available for analysis in 207 female (mean age = 52.91 years) and 192 male patients (mean age = 53.04 years). Female patients were found to have smaller aortae (at the level of the right renal ostium) and bilateral renal arteries than males (mean aortic diameter M/F = 18.33/15.89 mm, mean right renal artery ostial diameter M/F = 5.06/4.59 mm, mean left ostial renal diameter M/F = 5.14/4.66 mm) (p < .001). There was no statistical significance for the renal ostia level in relation to the vertebrae and the majority of renal arteries originated at the L1 and L2 levels. The longitudinal distance between right and left renal artery ostia ranged from 0 to 32 mm (mean = 4,6 mm, median = 5mm). The mean anteroposterior orientation of the right renal ostia was M/F = 29.45°/28.20°, and M/F = −7.96°/−11.14° for left renal artery ostia. The mean anteroposterior orientation of the right renal pedicle was M/F = 41.37°/44.34° and M/F = 42.31°/43.95° for the left pedicle. There are some differences in normal renal arterial anatomy between genders. Normal renal arterial information is useful not only for planning and performing of endovascular and laparoscopic urologic procedures, but also for medical device development. Clin.

Computational fluid dynamics (CFD) models in the learning process of Hydraulic Engineering
Authors: López P. A. , Mora J. J. , Martínez F. J. , Izquierdo J. 
Published: January 2009

AbstractIn this article, we show the ability to use sophisticated computational fluid dynamics (CFD) models as simple and useful tools in the learning process for Fluid Mechanics and Hydraulic Engineering topics. Specifically, we present a comparison between results obtained for a controlled layout simulated both by physical and computational models. This particular experience is based on a Venturi tube. In the laboratory of the Multidisciplinary Center for Fluid Modeling (CMMF), we have implemented a suitable assembly to simulate different Venturi‐related phenomena and to take measurements in an intrusion flow forced by the pressure field into the perforated Venturi tube. The same geometry has been reproduced using a CFD code, and both pressure and velocity values have been compared. By doing this comparison, we first provide awareness to our students about the importance of calibration, then show them the agreement between measured and computed values, and finally design a methodology for students to visualize pressure and velocity fields by means of a number of graphical displays of the results. This approach has revealed itself to be a powerful tool for them to understand the intricacies of hydraulic topics. © 2009 Wiley Periodicals, Inc.

Rank annihilation factor analysis for multicomponent kinetic‐spectrophotometric determination using difference spectra
Authors: Bahram Morteza , Mabhooti Mehdi 
Published: January 2009

AbstractIn this work rank annihilation factor analysis (RAFA) is used to analyze difference spectra of kinetic‐spectrophotometric data. Annihilation of the contribution of one chemical component from the original data matrix is a general method in RAFA. However, sometimes RAFA is not suitable for studying rank deficient data such as kinetic‐spectrophotometric measurements. On the other hand, in order to apply RAFA for the determination of an analyte in an unknown sample, a standard two‐way matrix of the analyte with rank one should generally be available. This is not usually attainable for kinetic‐spectrophotometric monitoring of complexation reactions. Processes monitored by difference spectroscopy always have the spectrum of the initial stage subtracted from each spectrum in the data matrix. In this work we show that, for kinetic‐spectrophotometric data of complexation reactions, the spectrum of ligand (reactant) itself can be used as initial spectrum for subtraction. The obtained difference matrix of sample and that of analyte of interest will be full‐rank and rank 1, respectively. Therefore the system can be analyzed by RAFA. The proposed method was investigated with simulated data at the first stage. The method was then applied in the analysis of experimental kinetic‐spectrophotometric data of a complexation reactions of Co(II) and Ni(II) with chromogenic reagent 1‐(2‐pyridylazo) 2‐naphthol in order to do multi‐component determination of these ions in various real samples.

Published: January 2009

AbstractObjectiveTo examine the effect of rosuvastatin on peripheral nerve function in diabetic rats using electrophysiological measurements.BackgroundDiabetes was induced in 5‐day‐old male Wistar rats by intraperitoneal (i.p.) injection of streptozotocin (STZ). As many as 45 diabetic rats were randomized to three groups: one treated with rosuvastatin (group R), another with rosuvastatin and mevalonate (group MR) and the other was untreated (group U). The data were compared with a group of normal age‐matched rats i.e. control rats (group C).MethodsNeurophysiological measurements were performed at the age of 3 months (T1) and again at the age of 8 months (T2), after 3 months of treatment.ResultsAt T1, there was a trend to lower amplitude of compound motor action potential (CMAP) in the three diabetic groups as compared to controls, and no difference for motor nerve conduction velocity (MNCV), amplitude of sensory nerve action potential (SNAP), sensory nerve conduction velocity (SNCV) between diabetic groups and controls. At T2, the amplitude of CMAP was significantly lower in groups R and MR versus group U and control rats. MNCV was significantly and similarly decreased in the three diabetic groups; the latency of the first sensory peak (fastest sensory fibres) was significantly increased in group U but was normal in groups R and MR.ConclusionsThis study shows that :

rosuvastatin exerts a beneficial effect on the conduction of the fastest sensory fibres;
these effects are independent of blood pressure and lipid changes.

Continuous subcutaneous insulin infusion (CSII) 30 years later: still the best option for insulin therapy
Authors: Bruttomesso Daniela , Costa Silvana , Baritussio Aldo 
Published: January 2009

AbstractThirty years after its introduction, the use of continuous subcutaneous insulin infusion (CSII) keeps increasing, especially among children and adolescents. The technique, when used properly, is safe and effective.Compared with traditional NPH‐based multiple daily injections (MDI), CSII provides a small but clinically important reduction of HbA1c levels, diminishes blood glucose variability, decreases severe hypoglycaemic episodes and offers a better way to cope with the dawn phenomenon.Insulin analogues have improved the treatment of diabetes, eroding part of the place previously occupied by CSII, but CSII still remains the first option for patients experiencing severe hypoglycaemic episodes, high HbA1c values or marked glucose variability while being treated with optimized MDI. Furthermore CSII is better than MDI considering the effects on quality of life and the possibility to adjust insulin administration according to physical activity or food intake.CSII may be limited by cost. Present estimates suggest that CSII may be cost‐effective just for patients experiencing a marked improvement in HbA1c or a decrease in severe hypoglycaemic episodes, but the effects on quality of life are difficult to measure.CSII does not merely imply wearing an external device; it requires a multidisciplinary team, intensive patient education and continuous follow up.

Elevated glutamate and NMDA disrupt production of the second messenger cyclic GMP in the early postnatal mouse cortex
Authors: Currie Douglas A. , Corlew Rebekah , de Vente Jan , Moody William J. 
Published: January 2009

AbstractThe second messenger cyclic guanosine monophosphate (cGMP) plays many roles during nervous system development. Consequently, cGMP production shows complex patterns of regulation throughout early development. Elevated glutamate levels are known to increase cGMP levels in the mature nervous system. A number of clinical conditions including ischemia and perinatal asphyxia can result in elevated glutamate levels in the developing brain. To investigate the effects of elevated glutamate levels on cGMP in the developing cortex we exposed mouse brain slices to glutamate orN‐methylD‐aspartate (NMDA). We find that at early postnatal stages when the endogenous production of cGMP is high, glutamate or NMDA exposure results in a significant lowering of the overall production of cGMP in the cortex, unlike the situation in the mature brain. However, this response pattern is complex with regional and cell‐type specific exceptions to the overall lowered cGMP production. These data emphasize that the response of the developing brain to physiological disturbances can be different from that of the mature brain, and must be considered in the context of the developmental events occurring at the time of disturbance. © 2009 Wiley Periodicals, Inc.

Effect of perceived anonymity in assessments of eating disordered behaviors and attitudes
Authors: Lavender Jason M. , Anderson Drew A. 
Published: January 2009

AbstractObjective:The present study assessed the effect of perceived anonymity on endorsements of eating disordered behaviors and attitudes across multiple response formats.Method:Four hundred sixty‐nine undergraduate women responded using one of three questionnaire formats: a nominally anonymous true/false condition, an unmatched count condition, or a randomized‐response condition. Both the unmatched count and randomized response conditions provided complete response anonymity.Results:Significantly different endorsement rates were found for the majority of items when comparing the standard and unmatched count conditions, whereas differences were found for fewer items when comparing the standard and randomized response conditions. Perceived anonymity significantly differed across conditions, with the highest and lowest perceptions of anonymity found for the unmatched count and standard conditions, respectively.Discussion:Perceived anonymity and response format affect endorsements of eating disordered behaviors and attitudes, highlighting the necessity of understanding factors that contribute to response bias. © 2009 by Wiley Periodicals, Inc.

Negative reinforcement eating expectancies, emotion dysregulation, and symptoms of bulimia nervosa
Authors: Hayaki Jumi 
Published: January 2009

AbstractObjective:Research suggests that emotion dysregulation or difficulties in the modulation of emotional experience constitute risk for eating disorders. Recent work has also highlighted the role of certain eating‐related cognitions, specifically expectations of negative emotional reinforcement from eating, in the development of disturbed eating patterns. However, it is unclear whether these expectancies are merely a dimension of a general inability to regulate emotions effectively or rather a unique cognitive‐affective risk factor for the development of an eating disorder. This study examines the unique contribution of eating expectancies to symptoms of bulimia nervosa (BN) after controlling for two dimensions of emotion dysregulation (alexithymia and experiential avoidance) previously implicated in the phenomenology of eating disorders.Method:Participants were 115 undergraduate women who self‐reported demographics, alexithymia, experiential avoidance, eating expectancies, and symptoms of BN.Results:Eating expectancies uniquely contributed 12.4% of the variance in symptoms of BN, F(2, 108) = 11.74, p < .001. The final model was statistically significant, F(6, 108) = 13.62, p < .001, and accounted for 40.0% of the variance in symptoms of BN.Discussion:These results suggest that individuals who expect eating to provide emotional relief may be especially susceptible to disordered eating. Findings are discussed in terms of emotional risk models and clinical interventions for BN. © 2009 by Wiley Periodicals, Inc. Int J Eat Disord 2009

AbstractWe investigated ethidium bromide intercalation into DNA molecule as a model system to test square‐wave voltammetry (SWV) as a suitable method for this purpose We found that 0.13 μg EtBr intercalates into 1 μg dsDNA in average. Further, SWV was utilized for investigation of doxorubicin‐DNA interactions. Intercalated doxorubicin reduced observed dsDNA cytosine and adenine (CA) signal, but also provided new signal called DOXO at −0.35 V. This phenomenon was observed at both single and double stranded DNA standards. We also employed adsorptive transfer stripping technique coupled with SWV for study of doxorubicin‐DNA interactions. Doxorubicin intercalation into dsDNA molecule adsorbed onto working electrode was fast, because we observed considerable changes in CA and DOXO signals after 360 s. Finally, we detected doxorubicin‐DNA adducts formed in doxorubicin treated neuroblastoma cells.
