Second‐look us examination of MR‐detected breast lesions
Authors: Candelaria Rosalind , Fornage Bruno D. 
Published: December 2010

AbstractPurpose:To review our institutional experience in using second‐look ultrasound (SLUS) to identify breast lesions initially detected on MR imaging that were indeterminate or suspicious for malignancy.Methods: This Health Insurance Portability and Accountability Act compliant retrospective review included 83 women with 131 lesions initially identified as indeterminate or suspicious for malignancy on MR imaging from February 1, 2008 through July 31, 2009. An SLUS correlate was confirmed on the basis of concordant location, size, and morphologic features. The detection rate of SLUS was determined. Patients' demographics, lesion size, and MR imaging morphologic features (focus, mass, non‐masslike) were reviewed to identify which factors led to successful detection on SLUS. Likelihood ratio χ2 tests were used for statistical analysis.Results: SLUS correlates were found for 88 of 131 (67%) lesions initially detected on MR imaging; 27 of 88 (31%) were malignant. SLUS detected foci (67%) and masses (73%) more frequently than it did non‐masslike lesions (54%). The detection rate of SLUS was independent of lesion size on MR imaging. Malignant lesions were not more likely than benign lesions to be detected on SLUS (61% versus 70%).Conclusions: SLUS provides value in the clinical workup of breast lesions that are indeterminate or suspicious for malignancy. It identified two thirds of the MR‐detected lesions evaluated and permitted performance of US‐guided needle biopsy on 70 of 88lesions. The likelihood of finding MR‐detected lesions on SLUS was significantly higher for foci and masses than for non‐masslike lesions (P

Published: December 2010

AbstractAccording to the World Reference Base for Soil Resources (IUSS Working Group WRB, 2006), the differentiation of Acrisols and Alisols is based on the cation‐exchange capacity of clay, which cannot be directly determined in the field, but needs expensive and time‐consuming soil‐chemical analyses. This is an unsatisfactory situation for pedologists, who urgently require a rapid field method to distinguish illuviation‐type reference soil groups (Alisols, Acrisols, Luvisols, Lixisols). In this study, we tested the ability of gamma‐ray spectrometry to separate major WRB reference soil groups in the field. The underlying hypothesis is that Alisols and Acrisols are distinguished by their clay mineral composition, which should be reflected by geochemistry and consequently gamma‐ray radiation (i.e., K‐containing illite vs. K‐free kaolinite).Highly significant differences in their gamma‐ray spectrum for K, Th, and U were found for limestone and its soils. Especially the K and Th signatures allowed a clear separation of Acrisols and Alisols. In general, the surface radiation was sufficient to separate these soils. Best results were revealed considering parent rock and the whole soil profile. This means by using a portable radiometer and a pH meter, all illuviation‐type reference soil groups could be distinguished in this case. If applicable at other sites, this approach could enormously reduce expenditures for soil‐chemical analysis needed to assist soil classification.

AbstractLack of environmentally safe handling of garbage is a growing problem in urban sub‐Saharan Africa (SSA). Composting the garbage for soil‐fertility management presents an opportunity for reducing the risks of environmental pollution. This study aimed at evaluating the agronomic effectiveness and nutrient‐utilization efficiency of urban market crop‐waste compost on a Eutric Ferralsol. The study was conducted in central Uganda with treatments including compost applied at 0, 5, and 10 t ha–1(d.w. basis); inorganic N fertilizer at rates of 0, 40, and 80 kg ha–1and inorganic P fertilizer at 0, 9, and 18 kg ha–1. Maize (Zea maysL.), variety Longe 4 was used as the test crop. The nutrient quality of the compost was medium with total N of 0.9% and total P of 0.45%. Compost significantly increased plant height, LAI, stover weight, and grain yield; however, there were no significant differences between the 5 and 10 t ha–1rates. Nitrogen also had a significant effect on LAI and stover yield, though there was no significant difference between the 40 and 80 kg ha–1rates. Likewise, P increased plant height with no significant difference between the 9 and 18 kg ha–1rates. Mineral N at 40 kg ha–1led to the highest increase in N uptake by plants (76%) above the control. Nitrogen‐ and P‐utilization efficiencies for the 5 t ha–1compost rate were more than twice that of the 10 t ha–1rate. The highest P‐utilization efficiency (69%) was obtained where 9 kg ha–1P was applied with 40 kg ha–1N, while the highest N‐utilization efficiency (48%) was obtained with the 5 t ha–1compost applied together with N at 40 kg ha–1. From the above studies, it is clear that effectiveness of the 5 t ha–1compost rate is the most promising.

Published: December 2010

AbstractVegetable‐production systems often show high soil mineral‐N contents and, thus, are potential sources for the release of the climate‐relevant trace gas N2O from soils. Despite numerous investigations on N2O fluxes, information on the impact of vegetable‐production systems on N2O emissions in regions with winter frost is still rare. This present study aimed at measuring the annual N2O emissions and the total yield of a lettuce–cauliflower rotation at different fertilization rates on a Haplic Luvisol in a region exposed to winter frost (S Germany). We measured N2O emissions from plots fertilized with 0, 319, 401, and 528 kg N ha–1 (where the latter three amounts represented a strongly reduced N‐fertilization strategy, a target value system [TVS] in Germany, and the N amount fertilized under good agricultural practices). The N2O release from the treatments was 2.3, 5.7, 8.8, and 10.6 kg N2O‐N ha–1 y–1, respectively. The corresponding emission factors calculated on the basis of the total N input ranged between 1.3% and 1.6%. Winter emission accounted for 45% of the annual emissions, and a major part occurred after the incorporation of cauliflower residues. The annual N2O emission was positively correlated with the nitrate content of the top soil (0–25 cm) and with the N surpluses of the N balance. Reducing the amount of N fertilizer applied significantly reduced N2O fluxes. Since there was no significant effect on yields if fertilization was reduced from 528 kg N ha–1 according to “good agricultural practice” to 401 kg N ha–1 determined by the TVS, we recommend this optimized fertilization strategy.

Published: December 2010

AbstractBackground and ObjectivesInferior vena cava (IVC) leiomyosarcomas are rare and are a relatively small subset of retroperitoneal sarcomas. The current approach is resection and ligation or reconstruction of the IVC. This study was undertaken to analyze the outcomes associated with the use of neoadjuvant radiotherapy and IVC reconstruction in the treatment of IVC leiomyosarcoma.MethodsA retrospective clinicopathological review of patients treated during a 10‐year period.ResultsFour patients were treated with neoadjuvant radiotherapy, median 47.5 Gy, all underwent margin negative resection with 75% of the tumors being high grade and all patients requiring resection of adjacent organs. Reconstruction of the IVC was performed with an autologous superficial femoral vein graft. There were no mortalities and the morbidity rate was 50%. At a median follow up of 37 months; two patients had a patent IVC, no patients had a local recurrence, and one patient developed a distant metastases treated successfully with metastectomy.ConclusionsNeoadjuvant radiotherapy and resection of the IVC leiomyosarcoma resulted in 100% local control, and all patients are alive at median follow up of 37 months. IVC reconstruction with the superficial femoral vein is safe and associated with acceptable short and long term morbidity. J. Surg. Oncol. 2011; 103:175–178. © 2010 Wiley‐Liss, Inc.

AbstractBackgroundAim of our study was to compare functional ability and physical activity in children and young adults who underwent surgery for a malignant bone tumor that was located around the knee.MethodsThis cross‐sectional study included 82 patients aged 8–25 years with a follow‐up of 1–5 years. The functional ability and the amount of physical activity were evaluated by means of questionnaires and objective instruments.ResultsThirty nine patients underwent limb‐salvage surgery (24 allograft and 15 endoprosthesis) and 43 underwent ablative surgery (27 amputations and 16 rotationplasty). Patients in the limb‐salvage group were significantly older at the time of surgery than patients in the ablative group (mean age 15.2 years vs. 13.2 years, P = 0.03). Apart from significantly better scores for the timed up and down stairs and various walking activities in the limb‐salvage group as compared to the ablative surgery group, no significant differences were seen for any of the outcome measures.ConclusionsOne to 5 years after limb‐salvage and ablative surgery due to a malignant bone tumor children and young adults do, apart from a few activities involving walking and climbing stairs, not differ with respect to overall functional ability and physical activity.

AbstractAimsAngiogenesis from thyroid cancer cell plays the important roles in post‐surgical persistent, recurrent, and metastatic papillary thyroid cancer (PTC). This study is to investigate the expression of angiopoietin‐1 (Ang‐1), angiopoietin‐2 (Ang‐2), Tek/Tie‐2 receptor, and vascular endothelial growth factors (VEGF) in normal, benign thyroid tissues and different stage of PTC. We expect angiogenetic factors are important in the presentation of local‐regional neck or distant metastases in PTC.Materials and ResultsA total of 101 tissues from the subjects underwent thyroidectomy were enrolled in the study. There were 22 control and 79 thyroid cancer patients in different TNM stagings were collected. Ang‐1 illustrated highest mean immunostaining score in metastatic group. Comparing with normal and benign thyroid tissues, thyroid cancer tissues illustrated significantly high expression of three angiogenetic factors and Tie‐2 receptor. Of the PTC, significantly high expression of three angiogenetic factors and Tie‐2 receptor were illustrated in recurrent cases. VEGF showed statistical difference in disease‐free cancer mortality, and recurrent groups.ConclusionsImmunochemical staining illustrated VEGF, Ang‐1, Ang‐2 expression in PTC tissues related to clinical staging; however, we need more information concerning these factors with long‐term follow‐up results.

Published: December 2010

AbstractBackgroundSentinel lymph node biopsy (SNLB) is the standard of care in staging of melanoma and other skin cancers. Early studies used lymphazurin (LZ) for SLNB. A national shortage of LZ promoted methylene blue (MB) as an alternate stain.ObjectiveThis study compares complication rates between LZ and MB in SLNB patients, and the reliability dyes in locating sentinel lymph nodes.MethodsCharts were reviewed for patients who underwent SLNB for skin cancers between September 2006 and November 2008 at Penn State Hershey Medical Center. The type and quantity of dye, the presence of blue stained sentinel nodes, and any complications were recorded.ResultsNinety‐three patients underwent SLNB (46 LZ, 47 MB). The amount of dye used was similar (avg. 0.93 ml LZ, 1.24 ml MB). The complication rate of LZ was 8.7%, and MB was 25.5%. There was significantly more (P = 0.003) skin graft complications in the MB patients (6/12) versus LZ (0/15).ConclusionsThere is a higher rate of complications with MB, especially with skin grafting. The reported risk of anaphylaxis with LZ has not been reported in volumes <2 ml. The sentinel lymph node identification rate is historically similar between dyes, and in this study was noted to be higher with LZ. J. Surg. Oncol. 2011; 103:421–425. © 2010 Wiley‐Liss, Inc.

Published: December 2010

AbstractThis paper examines the effect of mood on satisfaction derived from experiencing an iconic and immersive cultural performance in Guilin, China called Impression of Liusanjie using structural equation modeling. Mood, together with visitor expectations and performance evaluations, was found to be significantly related to satisfaction and future intentions to recommend the show to others. Satisfaction was more strongly related to experiential evaluation of the performance than with attribute evaluation. The results indicate that understanding the mood and experiential outcomes for visitors at a performance is important increasing satisfaction and word‐of‐mouth recommendations.

Farmers' land management practices and status of agricultural land in the Jos Plateau, Nigeria
Authors: Thapa G. B. , Yila O. M. 
Published: December 2010

ABSTRACTA wide range of land management practices, including application of fertilizers, contour‐plowing, stone bunds, mulching and agroforestry, have been adopted by farmers in the Jos Plateau to control degradation. This study examined the relative popularity of 13 land management practices based on mainly qualitative primary information collected through a questionnaire survey of 150 farm households and group discussions held during May to August 2007. The results of the analysis revealed four practices, namely, application of chemical fertilizers and farm yard manure, intercropping and crop rotation were highly popular. These practices generally need little technical skills, show positive short‐term benefits and short establishment time, suggesting that the benefits of increased productivity can be obtained quite quickly. Practices like agroforestry, mulching, legume cultivation and crop residue barriers were moderately popular as they take time, sometimes up to 3 years, before some benefits could be manifested. For farmers dependent on the farm income without any financial back‐up, this is too long as many do not have the economic capital to apply a practice that will only start showing benefits after a few years. The least popular practices were stone and earthen bunds, grass strips, alley cropping and contour‐plowing. These prove to be more labour intensive, and with dwindling labour force in the area, the adoption trend favours other practices requiring relative less labour. Farmers could not control land degradation effectively, despite their efforts made to manage land. Broad policy recommendations are made in line with findings of the analysis.

The influence of solid lubricant for improving tribological properties in turning process
Authors: Suresh Kumar Reddy N. , Nouari Mohammed 
Published: December 2010

AbstractControl of machining zone temperature is achieved by providing effective cooling and lubrication. Though cutting fluids are widely used to carry away the heat in metal cutting, they cannot be recommended in the light of ecological and economic manufacture. Hence, there arises a need to identify eco‐friendly and user‐friendly alternatives to conventional cutting fluids. The present work features a specific study of the application of molybdenum disulphide as solid lubricant for improving tribological properties in turning and to overcome the limitations that arise with the use of cutting fluids or while dry machining. An experimental setup developed has been used to maintain constant flow rate of solid lubricant powder continuously on to the workpiece and tool interface zone. Results are encouraging with overall improvement in machining properties in terms considered parameters as compared to wet and dry techniques, due to the reduction in friction at tool/work and tool/chip interface.

A parametric investigation of the friction performance of electroless Ni‐B coatings
Authors: Das Suman Kalyan , Sahoo Prasanta 
Published: December 2010

AbstractFriction performance of electroless Ni‐B coatings sliding against steel is experimentally investigated in this paper. Friction performance is measured in terms of coefficient of friction (COF) for varying tribological testing parameters such as load, speed and time. Taguchi‐based optimisation of the testing parameters is attempted to find the optimal combination of testing parameters for minimum COF. An analysis of variance reveals that all the testing parameters have significant influence on the friction performance of the coating. Also, the interaction between load and speed is found to affect the friction more compared with the rest of the interactions. The coating characterisation is done with the help of scanning electron microscopy (SEM), energy dispersive X‐ray and X‐ray diffraction analysis. It is found that the Ni‐B coating is amorphous in the as‐deposited condition but gradually turns crystalline with heat treatment. The sliding tracks observed with SEM showed that abrasive failure is the predominant wear mechanism. Copyright © 2010 John Wiley & Sons, Ltd.

Published: December 2010

AbstractFor the nth order nonlinear differential equation, y(n) = f(x, y, y′, …, y(n−1)), we consider uniqueness implies existence results for solutions satisfying certain (k + j)‐point boundary conditions, 1 ⩽ j ⩽ n − 1, and 1 ⩽ k ⩽ n − j. We define (k; j)‐point unique solvability in analogy to k‐point disconjugacy and we show that (n − j0; j0)‐point unique solvability implies (k; j)‐point unique solvability for 1 ⩽ j ⩽ j0, and 1 ⩽ k ⩽ n − j. This result is in analogy to n‐point disconjugacy implies k‐point disconjugacy, 2 ⩽ k ⩽ n − 1. © 2011 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim
