Effect of Lupin Cyclitols on Pea Aphid Probing BehaviourThe cyclitols: D-pinitol, D-chiro-inositol are naturally present in the tissues ofLupinus angustifolius. The effect of these cyclitols on the behaviour of the pea associated clone ofAcyrthosiphon pisumduring various stages of probing was studied. The main stage of probing studied was the stylet penetration in mesphyll and vascular bundle. D-pinitol, D-chiro-inositol and their mixture were exogenously applied to peaPisum sativumexplants and the aphid probing behaviour was evaluated using the Electrical Penetration Graph technique (EPG). Feeding of peas with cyclitols at a concentration of 10 mM, caused a selective accumulation of D-pinitol and D-chiro-inositol in stems, leaf petioles, and leaf blades. In aphid bodies, both cyclitols were traced, respectively, to the host plant treatment. The new cyclitols in pea tissues did not significantly affect the total duration and frequency of aphid activities during probing in peripheral as well as vascular tissues. However, the aphid behaviour on cyclitol-treated plants as compared to their behaviour on the control was slightly altered. Non-probing and probing in mesophyl prevailed among aphid activities during the initial period of stylet penetration. Aphids on D-pinitol+D-chiro-inositol-treated plants reached phloem vessels relatively later than aphids on the control and D-chiro-inositol plants. There were recurrent switches between E1 (salivation) and E2 (sap ingestion) patterns in some aphids during the phloem phase on D-pinitol and D-pinitol+D-chiro-inositol - treated plants. This may reflect difficulties in the uptake of the phloem sap, and point to lupin cyclitols as being responsible, at least in part, for the rejection ofL. angustifoliusas a host plant by the pea clone ofA. pisum.

Warning against warnings: Alerted subjects may perform worse. Misinformation, involvement and warning as determinants of witness testimony
The article presents experiments exploring the memory misinformation effect. Subjects heard a recording and afterwards read a description of it, which included, in the misled group, some details inconsistent with the recording; finally thay answered questions about the recording. The aim of the research was to replicate the tainted truth effect, consisting in poor memory functioning of non-misled warned subjects and to check whether a subject's involvement in the issue moderates this effect. Highly involved subjects were more resistant to the misinformation effect than those lowly involved. In the case of highly involved participants, warning was effective in reducing the misinformation effect, but it also caused more errors in the case of non-misled subjects. Thus, warning witnesses about nonexising discrepancies between what they saw/heard and what they were told, might lead to less accurate testimony.

Fusion of Data from Inertial Sensors, Raster Maps and GPS for Estimation of Pedestrian Geographic Location in Urban TerrainAn electronic system and an algorithm for estimating pedestrian geographic location in urban terrain is reported in the paper. Different sources of kinematic and positioning data are acquired (i.e.: accelerometer, gyroscope, GPS receiver, raster maps of terrain) and jointly processed by a Monte-Carlo simulation algorithm based on the particle filtering scheme. These data are processed and fused to estimate the most probable geographical location of the user. A prototype system was designed, built and tested with a view to aiding blind pedestrians. It was shown in the conducted field trials that the method yields superior results to sole GPS readouts. Moreover, the estimated location of the user can be effectively sustained when GPS fixes are not available (e.g. tunnels).

Thermal characterisation of Lake Morskie Oko water in 2007 based on measurements by a gradient thermal probeThe study was undertaken to illustrate a wide range of application of a gradient thermal probe in thermal characterisation of water reservoirs on the example of Lake Morskie Oko whose water temperature has been measured since 2006. For analysis, the data collected in 2007 were chosen because of the least missing data; in this year only the data from 13 days were not recorded. The data permitted analysis of changes in daily mean temperatures of water at particular depths, with the daily means calculated as arithmetic means from 144 measurements made at every 10 minutes. The daily amplitudes of temperatures at particular depths and mean daily amplitudes for particular months were determined, which permitted an assessment of the scale of the temperature amplitude damping with increasing depth. High frequency of temperature reading permitted detection of short-duration anomalies, taking place e.g. over a time span of 10 minutes, or their vertical extent. It has been established that measurement at 2 a.m. is the optimum for determination of the annual mean temperature. The time moments at which the minimum and maximum temperatures are recorded within a day at the surface were identified. Different variants of temporary jump changes in the surface water temperature within the day were analysed. The dynamics of temperature changes from the surface to the bottom of the lake was discussed.

Application of Phytotoxkit microbiotest for hazard assessment of bottom sediments in the eutrophic dam reservoir
The aim of this study was to estimate ecotoxicity of the sediments from the shallow, eutrophic dam reservoir - Sulejowski. Research was carried out using Phytotoxkit microbiotests, which measure inhibition of seeds germination and roots growth retardation of the three species of plants (dicotyl Lepidium sativum, Sinapis alba, monocotyl Sorgum saccharatum). Tested plants gave different response to sediment samples, with decreasing sensitivity gradient: L. sativum, S. saccharatum, S. alba. The relationship of phytotoxicity of sediments with its water content was recorded (r = 0.63, p < 0.05). The results obtained showed spatial diversification along the reservoir, with the highest values in its opposite ends of the upper and lower parts (up to 87%), which are separated by a central area with the lowest toxicity (up to 45%). Possible reasons and implications of bottom sediments phytotoxicity are discussed.

Published: April 2011

AIMS Internet gambling has been associated with Increased risk of problem gambling. In this study different clusters of gambling activities and behavioral measures of gambling were used In analyses, which aimed at Investigating prevalence of problem gambling in Internet poker gamblers and In other gamblers. DATA AND METHODS The study consisted of secondary analyses of a Finnish population data set collected in 2007 (telephone survey, reaching 5,008 Finns aged 15 years and over). Bivariate statistics and logistic regression models were used in the analyses. Results When only age and sex were added to logistic regressions, overseas Internet poker (IP) gamblers were almost three times more likely to be problem gamblers than other gamblers. However, when also behavioral measures of gambling were added to equations, no difference in problem gambling between IP and other gambling was found. In the slot machine (SM) cluster an opposite phenomena occurred: when behavioral variables were added to analyses, subjects in SM cluster were more likely to be problem gamblers than other gamblers. When IP and SM were compared in the same multivariate analysis, subjects in both of these gambling clusters were more likely to be problem gamblers than other gamblers. Conclusions The present study shows the importance of behavioral measures in gambling research. The level of involvement in gambling should be one of the primary interests in studies and interventions.

Published: April 2011

Background: The surgical indications, timing, and procedure for flexible flatfoot reconstruction in young patients remains controversial. This retrospective study reports the clinical results of reconstruction of flexible, idiopathic, symptomatic flatfoot in adolescent and young adults indicated for surgery by persistent pain and functional limitations. The hypothesis was that the results of these procedures allow patients to return to sports activities with minimal discomfort or pain. Materials and Methods: Sixteen consecutive idiopathic flatfeet in ten patients with a mean age of 15.6 years at the time of surgery (range, 10 to 22) were assessed at a final followup visit at average of 5.2 (range, 2 to 10) years. Reconstruction included combined medializing calcaneal osteotomy and lateral column lengthening in all 16 patients. Flexor digitorum longus transfer (nine), medial column stabilization (eight), and gastroncnemius recession (eight) were carried out as needed. The AOFAS, SF-36, and FAOS questionnaires were completed. Sports activity and patient satisfaction were also assessed. Standard preoperative and postoperative radiographic parameters were measured. Results: The mean AOFAS score increased on average from 49.1 to 93.4. Only one patient reported a postoperative restriction in sports. The satisfaction level was excellent in 15 feet and good in one foot. Significant improvement in radiographic parameters was noted for the AP talonavicular coverage angle ( p < 0.001) and lateral talar-first metatarsal angle ( p < 0.001). Conclusion: Flexible flatfoot reconstruction in a cohort of symptomatic adolescent and young adult patients achieved a reduction of pain and improved functional outcome including the ability to participate in sporting activities.

Talonavicular Joint Fixation Using Augmenting Naviculocalcaneal Screw in Modified Double Hindfoot Arthrodesis
Authors: Kiesau Carter D. , LaRose Connor R. , Glisson Richard R. , Easley Mark E. , DeOrio James K. 
Published: April 2011

Background: Triple arthrodesis and combined talonavicular/subtalar arthrodesis are procedures for hindfoot disorders. Achieving talonavicular joint fusion can be problematic. We hypothesized that talonavicular joint fixation bending stiffness could be increased by adding a fully-threaded screw inserted through the lateral navicular into the calcaneus. Materials and Methods: We used ten fresh-frozen cadaver hindfeet. The calcaneus and talus were immobilized, and talonavicular joint stripped of cartilage. Two partially-threaded 4.5-mm cannulated screws were placed across the talonavicular joint, one traversing the central third of the navicular and a second through the medial third of the navicular. We quantified talonavicular fixation bending stiffness and angulation in response to 4N-m bending moments applied to the navicular in four directions: plantar-to-dorsal (P-D), medial-to-lateral (M-L), dorsal-to-plantar (D-P), and lateral-to-medial (L-M). An augmenting fully-threaded 4.5 mm cannulated screw was then placed through the lateral third of the navicular into the calcaneus and the specimens retested. Results: The mean bending stiffness in each direction increased significantly after addition of the third screw. The stiffness increase in each direction was: P-D 92%, D-P 39%, L-M 108%, and M-L 56%. Correspondingly, mean talonavicular angulation significantly decreased in each direction: P-D 43%, D-P 28%, L-M 47%, and M-L 34%. Conclusion: A third, fully-threaded screw from the lateral navicular into the calcaneus significantly increases talonavicular bending stiffness and decreases angulation. Clinical Relevance: The increased resistance to arthrodesis site motion afforded by the addition of a naviculocalcaneal screw may improve the likelihood of achieving successful talonavicular fusion in combined talonavicular/subtalar arthrodesis.
Outcomes of Suture Button Repair of the Distal Tibiofibular Syndesmosis
Authors: DeGroot Henry , Al-Omari Ali A. , Ghazaly Sherif Ahmed El 
Published: April 2011

Background: Recently, a suture button device has been advocated as a simple and effective method of repairing the syndesmosis. Proponents of the device have cited earlier weightbearing and elimination of the need for device removal as potential advantages over metallic screws. However, the available reports generally have short followup. With longer followup, some concerns about the suture button device have surfaced. Materials and Methods: We reviewed the clinical and radiographic results of 24 patients with acute injuries to the distal tibiofibular syndesmosis who were treated with suture button fixation. Average followup was 20 months. The primary outcomes measure was the AOFAS ankle hindfoot score. Secondary outcomes measures included a calibrated measurement of the tibiofibular clear space and tibiofibular overlap. Results: The average AOFAS score was 94 points. Syndesmotic parameters returned to normal after surgery and remained normal throughout the followup period. One in four patients required removal of the suture endobutton device due to local irritation or lack of motion. Osteolysis of the bone and subsidence of the device into the bone was observed in four patients. Three patients developed heterotopic ossification within the syndesmotic ligament, one mild, one moderate, and one who had a nearly complete syndesmotic fusion. Conclusion: The suture button device is an effective way to repair the syndesmosis. In our series, the reduction of the syndesmosis was maintained throughout the followup period. However, reoperation for device removal was more common than anticipated. Osteolysis of the bone near the implant and subsidence of the device may occur.

Radiographic Analysis of an Opening Wedge Osteotomy of the Medial Cuneiform
Authors: Lutz Michael , Myerson Mark 
Published: April 2011

Background: Forefoot varus deformity and medial column instability can develop or be present in association with ankle and hindfoot pathology. This study aimed to confirm the utility of medial cuneiform opening wedge osteotomy as part of hindfoot and ankle deformity correction. Materials and Methods: Patients requiring operative management of flatfoot deformity between January 2002 and December 2007 were prospectively entered in a database. We selected all patients who underwent medial cuneiform opening wedge osteotomy. One hundred and one feet in 86 patients of mean age 36 (range, 9 to 80) years were evaluated. Eighty-one feet had adequate radiographic imaging for assessment. Concomitant procedures were performed. We measured standardized, validated radiographic parameters on pre- and postoperative weightbearing foot radiographs. Variables including concomitant surgical procedures, osteotomy union, malunion, and midfoot arthritis were noted. Results: The mean lateral talus-first metatarsal angle improved from 23 degrees to 1 degrees ( p < 0.001); mean medial cuneiform to floor distance improved from 20 mm to 34 mm ( p < 0.001); mean talar declination angle improved from 39 degrees to 27 degrees ( p < 0.001); mean calcaneal-talar angle improved from 64 degrees to 55 degrees ( p < 0.001); calcaneal pitch angle improved from 14 degrees to 23 degrees ( p < 0.001); mean first metatarsal declination angle improved from 17 degrees to 26 degrees ( p < 0.001); mean talonavicular coverage angle improved from 45 degrees to 18 degrees ( p < 0.001); and mean anteroposterior talus-first metatarsal angle improved from 19 degrees to 0 degrees ( p < 0.001). Conclusion: Radiograph-ical analysis showed that medial cuneiform opening wedge osteotomy combined with other corrective procedures corrected forefoot varus, elevated first metatarsal and medial column instability radiographic parameters that are most commonly associated with flatfoot deformity.

Published: April 2011

Background: The aim of this study was to describe the difference between the medial distal tibial angle (MDTA) when measured on whole lower limb radiographs and mortise radiographs of the ankle. Materials and Methods: A total of 48 legs were included of 24 healthy volunteers. Standard radiographs were obtained of the whole lower leg. Mortise radiographs were obtained of the ankle. The MDTA was measured on the digitized radiographs by three orthopaedic residents, one orthopaedic surgeon and one biomechanical movement scientist. For each leg, the angles measured from the two images were compared. The inter-observer reliability of each method was calculated. Results: The MDTA as measured on whole lower leg images (94.6 ± 2.6 degrees) was significantly different compared with the angle measured on mortise ankle images (92.1 ± 2.2 degrees) ( p < 0.01). The mean measurement difference between observers was less than 1 degree. Reliability of the measurements was good with a high association (κ = 0.85) between observers for the angles measured on the whole lower leg images and also a high association (κ = 0.83) between the observers for the mortise ankle image measurements. Conclusion: The MDTA is not the same on whole lower leg images and mortise views of the ankle. There was an excellent interobserver reliability for the angles measured. Clinical Relevance: Foot and ankle surgeons should take this into account when planning coronal deformity correction of the distal tibia. We believe whole lower leg images should be used to assess the medial distal tibial angle.
