Triple-point defective surfaces
Authors: Chiantini Luca , Markwig Thomas 
Published: July 2010

Abstract
In this paper we study the linear series |L – 3p| of hyperplane sections with a triple point p on a surface S embedded via a very ample line bundle L for a general point p. If this linear series does not have the expected dimension we call (S, L) triple-point defective. We show that on a triple-point defective surface through a general point every hyperplane section has either a triple component or the surface is rationally ruled and the hyperplane section contains twice a fibre of the ruling.
Three-dimensional modeling of the structure formation and consolidation of wood composites
Authors: Drolet François , Dai Chunping 
Published: July 2010

AbstractA new three-dimensional (3D) computer simulation model is proposed to study structure development in wood composites, particularly strand or short fiber wood composites. The model takes into account the stochastic positioning and orientation of the strands within the mat. It also predicts the response of individual strands within the structure to the compressive and shear forces produced during mat consolidation. The model provides a complete description of mat structure in three dimensions, including spatial distribution of porosity, inter-strand contact, and density. Predictions for porosity obtained with the 3D model compare very well with those from an earlier two-dimensional analytical model. Mat structure is dictated by mat density in a two-step process: rapid removal of macrovoids before the mat density reaches the original wood density and asymptotic elimination of microvoids at higher mat densification. Other factors of importance include original wood density and strand dimensions, particularly strand thickness and width. Although known for its influence on mechanical properties, strand orientation seems to have little effect on mat porosity and strand contact.

Abstract
This paper reports the evaluation tests on the reliability and validity of a three-dimensional (3D) laser body scanner for the estimation of body volume and percent fat. Repeated measures of body imaging were performed for reproducibility analysis. The validity of the instrument was assessed by the comparison of the measures of body volume by imaging to hydrodensitometry, and body fat was compared to hydrodensitometry and dual energy X-ray absorptiometry. Reproducibility analysis showed little difference between within-subjects measurements of volume (intraclass correlation coefficient (ICC)≥0.99 and p&lt;0.01). Body volume estimations by laser body scanner and hydrodensitometry were strongly related (r=0.99 and p&lt;0.01), and agreement was high (ICC=0.99 and p&lt;0.01). Measurements of percent body fat also agreed strongly with each other between methods (ICC=0.86 and p&lt;0.01), and mean percent fat estimates by body imaging did not differ from criterion methods (p&gt;0.05). These findings indicate that the 3D laser body scanner is a reliable and valid technique for the estimation of body volume. Furthermore, body imaging is an accurate measure of body fat, as compared to dual energy X-ray absorptiometry. This new instrument is promising as a quick, simple to use, and inexpensive method of body composition analysis.
A novel method for radiochemical separation of radioyttrium from Sr targets using precipitation technique
Authors: Sadeghi Mahdi , Zali Akram , Avila Mario 
Published: July 2010

Abstract
A method is described for separating radioyttrium from strontium within 30−40 min. The yield of radioyttrium amounts to 97% and the strontium impurity occurs at 8.2 ppm level. Radioyttrium (containing 86Y, 87Y and 88Y) was produced by proton-induced nuclear reactions on natSrCO3 deposited on Cu backing. Irradiated target material was removed with acetone and 8 M HCl solution from copper substrate, followed by ethyl cellulose (EC) filter removal. Optimal radioyttrium separations from Cu and 65Zn activities were obtained by loading the mixture on Dowex-1×8 anion exchange resin and eluting with 8 M HCl, followed by precipitation of natSr as SrSO4 while radioyttrium passed through the filter paper.
Accidental Amplification and Inactivation of a Methyltransferase Gene Eliminates Cytosine Methylation inMycosphaerella graminicola

Published: July 2010

AbstractA de novo search for repetitive elements in the genome sequence of the wheat pathogen Mycosphaerella graminicola identified a family of repeats containing a DNA cytosine methyltransferase sequence (MgDNMT). All 23 MgDNMT sequences identified carried signatures of repeat induced point mutation (RIP). All copies were subtelomeric in location except for one on chromosome 6. Synteny with M. fijiensis implied that the nontelomeric copy on chromosome 6 served as a template for subsequent amplifications. Southern analysis revealed that the MgDNMT sequence also was amplified in 15 additional M. graminicola isolates from various geographical regions. However, this amplification event was specific to M. graminicola; a search for MgDNMT homologs identified only a single, unmutated copy in the genomes of 11 other ascomycetes. A genome-wide methylation assay revealed that M. graminicola lacks cytosine methylation, as expected if its MgDNMT gene is inactivated. Methylation was present in several other species tested, including the closest known relatives of M. graminicola, species S1 and S2. Therefore, the observed changes most likely occurred within the past 10,500 years since the divergence between M. graminicola and S1. Our data indicate that the recent amplification of a single-copy MgDNMT gene made it susceptible to RIP, resulting in complete loss of cytosine methylation in M. graminicola.
Soil analysis (for plant nutrition) in Hungary: Practice and results

Published: July 2010

Agricultural goods obtained and produced in Hungary have played an important role in the markets of Western Europe. By utilizing the ecological potentials of the Carpathian Basin, local inhabitants are in the position to produce considerable food surpluses in addition to meeting their own demands. With agricultural production becoming more and more intensive in Hungary, the application of mineral fertilizers also started to increase slowly from the 1960’s. From the mid-1970’s a uniform sampling, soil testing and fertilization extension system was created together with its own institutional and laboratory testing network. The intensive use of mineral fertilizers in Hungary lasted from the mid-1970’s to the last quarter of the 1980’s, during which an average amount of 230 kg·ha
-1
NPK fertilizer was applied. In this period the so-called “build-up” fertilization was applied in conformity with the improvement of all other elements involved in the production technology, which was also clearly expressed in the agro-political objectives of those days aiming to obtain higher yields. At that time the nutrient supply and nutrient base of soils in Hungary increased clearly, so the production technology could no longer limit higher yields. In 1990 agriculture changed fundamentally and radically in Hungary, and the same was valid for nutrient supplies as well. At the beginning of the 1990’s there was a sudden decrease in the level of mineral fertilizer application (to below 40 kg NPK active ingredients·ha
-1
), followed by a slow increase, which has reached the level of almost 70 kg·ha
-1
by today. In the meantime the animal stock in Hungary has decreased and consequently the amount of manure has also fallen. All in all, the nutrient balance of Hungarian soils has always been negative since 1989. Due to the changes in its structure and ownership over the past twenty years or so, it has become very difficult to obtain reliable information about Hungarian agriculture. The Soil Resources Management General Partnership (in Hungarian: Talajerőgazdálkodás Kkt.) conducts extension work based on soil sampling and has a continuous flow of data on over thirty thousand hectares, beginning at the end of the 1970’s. Based on the analyses of these data it can be stated that the extra amount of nutrients over balance, applied during the period of replenishment (until the change in regimes) has been „removed” from the soil over the past fifteen years, consequently the Hungarian nutrient balance has become negative again. This kind of fertilization practice cannot be sustained in Hungary, as the maintenance of the production potential of Hungarian soils is far from being resolved at the moment; it poses risks to and questions sustainability, as well as it may cause a very serious competitive disadvantage to the country.

Patients with minor bleeding during treatment using oral anticoagulation, who are free from risk of other complications, can benefit from the use of aminaphtone as an initial therapeutic option.
A Dutch Survey on Circumpatellar Electrocautery in Total Knee Arthroplasty
Authors: van Jonbergen Hans-Peter W. , Barnaart Alexander F.W. , Verheyen Cees C.P.M. 
Published: July 2010

Introduction:Anterior knee pain following total knee arthroplasty is estimated to occur in 4-49% of patients. Some orthopedic surgeons use circumpatellar electrocautery (diathermy) to reduce the prevalence of postsurgical anterior knee pain; however, the extent of its use is unknown.Materials and Methodology:In April 2009, a postal questionnaire was sent to all 98 departments of orthopedic surgery in The Netherlands. The questions focused on the frequency of total knee arthroplasties, patellar resurfacing, and the use of circumpatellar electrocautery.Results:The response rate was 92%. A total of 18,876 TKAs, 2,096 unicompartmental knee arthroplasties, and 215 patellofemoral arthroplasties are performed yearly in The Netherlands by the responding orthopedic surgeons. Of the orthopedic surgeons performing TKA, 13% always use patellar resurfacing in total knee arthroplasty for osteoarthritis, 49% use selective patellar resurfacing, and 38% never use it. Fifty-six percent of orthopedic surgeons use circumpatellar electrocautery when not resurfacing the patella, and 32% use electrocautery when resurfacing the patella.Conclusion:There is no consensus among Dutch orthopedic surgeons on the use of patellar resurfacing or circumpatellar electrocautery in total knee replacement performed for osteoarthritis. A prospective clinical trial is currently underway to fully evaluate the effect of circumpatellar electrocautery on the prevalence of anterior knee pain following total knee arthroplasty.

A characterization of the 0-basis homogeneous bounding degrees
Authors: Lange Karen 
Published: July 2010

AbstractWe say a countable model has a 0-basis if the types realized in are uniformly computable. We say has a (d-)decidable copy if there exists a model ≅ such that the elementary diagram of is (d-)computable. Goncharov, Millar, and Peretyat'kin independently showed there exists a homogeneous model with a 0-basis but no decidable copy. We extend this result here. Let d ≤ 0′ be any low2 degree. We show that there exists a homogeneous model with a 0-basis but no d-decidable copy. A degree d is 0-basis homogeneous bounding if any homogenous with a 0-basis has a d-decidable copy. In previous work, we showed that the non low2 Δ20 degrees are 0-basis homogeneous bounding. The result of this paper shows that this is an exact characterization of the 0-basis homogeneous bounding Δ20 degrees.

Ecumenical Dialogue in Slovakia in the Context of Ecumenism of the Catholic Church
This contribution describes basic moments of ecumenical dialogue. It desribes short history of ecumenical dialogue from the side of Catholic Church. Main scope is to point on the relationships between Catholic Church and Orthodox church. This contribution decribes prognosis of the ecumenical perspectives in Slovakia in the dogmatic field and how looks practical ecumenism in Slovakia and in general also. In common proclamation with Athenian archbishop Christolodoulos, pope Benedict XVI expressed his desire to travel together along the arduous route of a dialogue in truth with a view to re-establish the full communion of faith.

Published: July 2010

Object
Extracranial-intracranial (EC-IC) bypass surgery remains an important treatment alternative for patients with occlusive cerebrovascular disease. The aim of the present study was to use perfusion CT and CT angiography (CTA) to evaluate cerebral hemodynamics and bypass patency in patients with occlusive cerebrovascular disease before and after EC-IC bypass surgery.

Methods
Ten patients underwent perfusion CT and CTA before and after bypass surgery. Preoperative and postoperative digital subtraction angiography served as the diagnostic gold standard. An artery bypass was established from the superficial temporal artery to a cortical branch of the middle cerebral artery. Perfusion CT scanning was performed at the level of the basal ganglia. Color-coded perfusion maps of cerebral blood volume, cerebral blood flow, and time to peak were calculated.

Results
Preoperative perfusion CT showed significant prolonged time to peak and reduced cerebral blood flow of the affected hemisphere. Postoperative neurological deterioration did not develop in any patient. Computed tomography angiography provided adequate evaluation of the anastomoses as well as the course and caliber of the bypass and confirmed bypass patency in all patients. Postoperative perfusion CT showed improved cerebral hemodynamics with a return to nearly normal perfusion parameters.

Conclusions
Computed tomography angiography is a noninvasive and reliable tool for evaluating patients with EC-IC bypass. Perfusion CT allows monitoring of hemodynamic changes after bypass surgery. The combination of both modalities enables noninvasive anatomical and functional analysis of superficial temporal artery–middle cerebral artery anastomoses using a single CT protocol. Hemodynamic evaluation of patients with occlusive cerebrovascular disease before and after surgery may improve the prediction of outcome and may help identify patients in whom a bypass procedure can be performed.

Background Because high serum low-density lipoprotein (LDL) and total cholesterol concentrations before treatment have been found to be significant positive prognostic factors for a sustained virological response to HCV therapy in monoinfected patients, the aim of this study was to assess this relationship in HIV–HCV-coinfected patients. Methods Pretreatment fasting lipid parameters (in particular total cholesterol, LDL, high-density lipoprotein [HDL], apolipoprotein B [apoB] and triglycerides [TG]) were assessed in 315 patients from the French National Agency for Research on AIDS and Viral Hepatitis (ANRS) HC02-Ribavic therapeutic trial. Results There was a significant correlation between pretreatment lipid parameters and steatosis (total cholesterol r=-0.23, P<0.0001; LDL r=-0.23, P<0.0001; HDL r=-0.28, P<0.0001; and TG r=0.18, P=0.002), but not with fibrosis. None of these lipid parameters were significant predictors of a sustained virological response to HCV therapy, even after adjustment for the type of interferon treatment and for the main known prognostic factors for a response to HCV therapy. Conclusions The possible effect of lipid metabolism on virological response is outweighed by other prognostic factors that affect response to HCV therapy in the ANRS HC02-Ribavic study.

Published: July 2010

Abstract
TNF-like weak inducer of apoptosis, TWEAK, is a typical member of the TNF ligand family. Thus, it is initially expressed as a type II transmembrane protein from which a soluble variant can be released by proteolytic processing. In this study, we show that membrane TWEAK is superior to soluble variant of TWEAK (sTWEAK) with respect to the activation of the classical NF-κB pathway, whereas both TWEAK variants are potent inducers of TNFR-associated factor-2 depletion, NF-κB–inducing kinase accumulation and p100 processing, hallmarks of activation of the noncanonical NF-κB pathway. Like other soluble TNF ligands with a poor capability to activate their corresponding receptor, sTWEAK acquires an activity resembling those of the transmembrane ligand by oligomerization or cell surface-immobilization. Blockade of the Fn14 receptor inhibited NF-κB signaling irrespective of the TWEAK form used for stimulation, indicating that the differential activities of the two TWEAK variants on classical and noncanonical NF-κB signaling is not related to the use of different receptors.

AbstractObjectiveSjögren's syndrome (SS) is a systemic autoimmune disease with a variety of presenting symptoms that may delay its diagnosis. We previously discovered a number of candidate salivary biomarkers for primary SS using both mass spectrometry and expression microarray analysis. In the current study, we aimed to verify these candidate biomarkers in independent patient populations and to evaluate their predictive values for primary SS detection.MethodsIn total, 34 patients with primary SS, 34 patients with systemic lupus erythematosus (SLE), and 34 healthy individuals were enrolled for the validation studies. Salivary protein biomarkers were measured using either Western blotting or enzyme‐linked immunosorbent assay, and the messenger RNA (mRNA) biomarkers were measured using quantitative polymerase chain reaction. Statistical analysis was performed using R software, version 2.9.ResultsThree protein biomarkers (cathepsin D [CPD], α‐enolase, and β2‐microglobulin [β2m]) and 3 mRNA biomarkers (myeloid cell nuclear differentiation antigen [MNDA], guanylate binding protein 2 [GBP‐2], and low‐affinity IIIb receptor for the Fc fragment of IgG) were significantly elevated in patients with primary SS compared with both SLE patients and healthy controls. The combination of 3 protein biomarkers, CPD, α‐enolase, and β2m, yielded a receiver operating characteristic (ROC) value of 0.99 in distinguishing primary SS from healthy controls. The combination of protein biomarkers β2m and 2 mRNA biomarkers, MNDA and GBP‐2, reached an ROC of 0.95 in discriminating primary SS from SLE.ConclusionWe have successfully verified a panel of protein and mRNA biomarkers that can discriminate primary SS from both SLE and healthy controls. If further validated in patients with primary SS and those with sicca symptoms but no autoimmune disease, these biomarkers may lead to a simple yet highly discriminatory clinical tool for diagnosis of primary SS.
Exploring the relationship between weaning and infant mortality: An isotope case study from Aşıklı Höyük and Çayönü Tepesi

Published: July 2010

AbstractWe measured stable nitrogen isotope ratios in bone collagen of 60 individuals from the early Neolithic (9th–8th millennium Cal. BC) sites of Çayönü Tepesi and Aşıklı Höyük. Our aim was to identify the duration of exclusive breastfeeding (EBF), compare this with juvenile mortality at each site, and assess whether there was a relationship between them. The isotope analysis suggests that weaning commenced at about 1 year at Aşıklı Höyük and around 2 years at Çayönü Tepesi. The mortality data show equal numbers of infant deaths up to 24 months; however, after 24 months, the mortality rate increases at Çayönü Tepesi, and a Student's t‐test confirms a significant difference in infant mortality between the sites. Weaning foods prepared in the early Neolithic from agricultural crops would have had low‐iron content, poor nutritional value, and would have been prepared in nonsterilized containers. Therefore, later weaned infants in early Neolithic farming settlements, although capable of some immunological response, were probably undernourished putting them at a disadvantage when encountering bacteria in their weaning food. Our results suggest that infant feeding regimes that introduced infants to weaning foods in the first year of life may have had a positive effect on their survival.
