Published: April 2013

AbstractBackgroundThe aim of this study was to assess airway hyperresponsiveness to eucapnic voluntary hyperventilation and dry powder mannitol challenge in athletes aiming to participate at the Paralympic Games 2008 in Beijing, especially in athletes with spinal cord injury.MethodsForty-four athletes with a disability (27 with paraplegia (group 1), 3 with tetraplegia (group 2) and 14 with other disabilities such as blindness or single limb amputations (group 3) performed spirometry, skin prick testing, measurement of exhaled nitric oxide, eucapnic voluntary hyperventilation challenge test (EVH) and mannitol challenge test (MCT). A fall in FEV1 of ≥10% in either challenge test was deemed positive for exercise-induced bronchoconstriction.ResultsFourteen (32%) athletes were atopic and 7 (16%) had a history of physician-diagnosed asthma. Absolute lung function values were significantly lower in patients of group 1 and 2 compared to group 3. Nine (20%) athletes were positive to EVH (8 paraplegics, 1 tetraplegic), and 8 (18%) athletes were positive to MCT (7 paraplegics, 1 tetraplegic). Fourteen (22.7%) subjects were positive to at least one challenge; only three athletes were positive to both tests. None of the athletes in group 3 had a positive test. Both challenge tests showed a significant association with physician-diagnosed asthma status (p = 0.0001). The positive and negative predictive value to diagnose physician-diagnosed asthma was 89% and 91% for EHV, and 75% and 86% for MCT, respectively.ConclusionEVH and MCT can be used to identify, but especially exclude asthma in Paralympic athletes.
Culture-related decision conflicts in the translation process
Authors: Loogus Terje 
Published: April 2013

Translators as members of a certain culture, generally that of the target culture, base their translation-relevant decisions on their own culture, while the decisions are motivated by the (alien) source culture. In the translation process, cultural differences may lead to various decision-making conflicts and the translator has to find a compromise between the author of the source text, the target recipient and finally, of course, the translator him/herself. In this article, proceeding from functionalist approaches to translation, the discussion focuses on the decision conflicts related to translating culturespecific elements. Culture-related decision conflicts, as considered here, refer to the translator's inner indecision with reference to his/her goals, interests, values, beliefs, methodological approach, or any consequences thereof, attributable to the different cultural embeddings of the source text and the target text. In general, decision conflicts are perceived as subjective translation problems. The translator has to be able to constantly act between separate perspectives, continuously see things from different viewpoints. The conflicts arise when the translator attempts to bring together two incongruent cultures without prejudice to any of the parties involved in the process. Acting within the interface of two different cultures, bearing in mind the interests of several participants, is what makes translation-relevant decisions a highly complex matter.
Theses about the poietic principle of metonymy
Authors: Pilv Aare 
Published: April 2013

The paper observes the relation of fictional/figural discourses to language-games that are active in reality. The starting point for the discussion is the "theory of two contexts" by Arne Merilai, the basic idea of which is distinguishing between fictional and factual speech acts on the basis of their different contexts of truth value. It seems to be justified to expand it to the whole sphere of figurality. After that the paper views John Gibson’s Wittgensteinian theory of fiction as an archive of standards/etalons of languagegames and a laboratory of reshaping and creating these standards. The fictional/figural sphere can be described as the area of possibility that creates language-games of reality via poiesis. The article describes some cases where the logic of figural sphere is introduced directly into real political discourse, forcing the reality to act according to the rules of art, but thus excluding the ethical freedom of our real-life language-games. It means that there exists a certain principle of metonymy between the figural sphere as archive and laboratory of standards, on the one hand, and the language-games of reality, on the other hand, while violation of that principle involves a danger of losing the reconciliatory power of fictionality/figurality that, according to Jaak Tomberg, is a significant function of literature as a human practice. There are several possibilities for further analysis: the cases where the danger can be turned into something positive; the problems and gains of art forms (certain forms of the theatre, happenings) that use techniques of intrusion into reality; the question if such violation of the "principle of metonymy" is specifically connected with modernist avant-gardism or not.
On the Selection of Bypassing Schemes Affecting the Secondary Arc Current and TRV in Series Compensated Lines
Authors: Zandi Zeynab , Sheshyekani Keyhan , Afjei Ebrahim 
Published: April 2013

Abstract
This paper investigates the effect of different bypassing schemes and grounding methods on the secondary arc current and the transient recovery voltage (TRV) of series compensated transmission lines. It is known that in series compensated lines, the peak value of the TRV may exceed the insulation strength. Furthermore, a secondary arc current is generated during a single line to ground fault mainly affected by the capacitive coupling between the healthy lines and the faulted line and can persist for seconds. The steadiness of secondary arc current prevents line reclosers from having a prompt closing to fulfill the system stability. This paper discusses different scenarios that can be employed to limit the secondary arc current consistency and to suppress a severe TRV during a single line to ground fault. A frequency domain analysis is conducted to better understand the nature of the secondary arc current. It is noted that an accurate arc model based upon the Kiziclay’s arc model is used in the simulations.
Effect of Air Velocity and Temperature on the Drying Kinetics of Drumstick Leaves (Moringa Oleifera)
Authors: Premi Monica , Sharma Harish , Upadhyay Ashutosh 
Published: April 2013

Abstract
The present study examines the effect of air velocity on drying kinetics of the drumstick leaves in a forced convective dryer. The drumstick leaves were dried in the temperature range of 50–800 C, at different air velocity (Dv) of 0.5 and 1.3 m/s. The results indicated that drying temperature and air velocity are the factors in controlling the drying rate. Experimental data obtained for the samples for color, drying rate and drying time proved that air velocity of 1.3 m/s yielded the product superior in terms of both quality and energy efficiency as compared to the samples at 0.5 m/s. Activation energy for drumstick leaves dried with air velocity, 0.5 and 1.3 m/s was 12.50 and 32.74 kJ/mol respectively. The activation energy relates similarly with the effective moisture diffusivity which also increased with increase in air velocity and temperature.

Published: April 2013

Abstract
In the present study carob molasses (pekmez) was spray dried to obtain a powder with desired improved handling properties. Maltodextrin with dextrose equivalent (DE) values of 8.6, 15.3 and 18.6 was used as a drying agent. Different molasses to maltodextrin ratios (25:75, 50:50), and dryer air inlet temperatures (160 °C, 210 °C) were additional parameters. The spray dried powders were analyzed for glass transition temperature, moisture content, water activity, wetting behavior, particle size, color, total phenolic content and antioxidant activity. The expected increasing effect of decreasing DE value on the glass transition temperature was obscured by different moisture contents. The glass transition temperature was mainly lowered by increasing the pekmez to maltodextrin ratio but also by increasing the air inlet temperature resulting in increasing moisture content. Wetting behavior was strongly influenced by the DE value. Total phenolic content was reduced in general by about 10 % and antioxidant activity changed by about 20 % independent from the investigated parameters. It can be concluded that spray drying of pekmez with addition of maltodextrin is a suitable method to improve and adjust handling properties of pekmez without loss of its nutritional value.

Authors: Dempwolff Ulrich , Müller Peter 
Published: April 2013

Abstract
We describe two classes of permutation polynomials over finite fields F in characteristic 2 of the shape L(X)Xk where L(X) is an additive polynomial. Such polynomials determine translation planes of order |F|. We show that our polynomials define new classes of translation planes and we compute the automorphisms of these planes

AbstractProteoglycans (PGs) regulate diverse functions in the central nervous system (CNS) by interacting with a number of growth factors, matrix proteins, and cell surface molecules. Heparan sulfate (HS) and chondroitin sulfate (CS) are two major glycosaminoglycans present in the PGs of the CNS. The functionality of these PGs is to a large extent dictated by the fine sulfation patterns present on their glycosaminoglycan (GAG) chains. In the past 15 years, there has been a significant expansion in our knowledge on the role of HS and CS chains in various neurological processes, such as neuronal growth, regeneration, plasticity, and pathfinding. However, defining the relation between distinct sulfation patterns of the GAGs and their functionality has thus far been difficult. With the emergence of novel tools for the synthesis of defined GAG structures, and techniques for their characterization, we are now in a better position to explore the structure-function relation of GAGs in the context of their sulfation patterns. In this review, we discuss the importance of GAGs on CNS development, injury, and disorders with an emphasis on their sulfation patterns. Finally, we outline several GAG-based therapeutic strategies to exploit GAG chains for ameliorating various CNS disorders.

Abstract

Background: The Japanese Association of Medical Technologists (JAMT) sought to establish common reference intervals (RIs) applicable nationwide in Japan for 27 serum constituent analytes for which certified reference materials are available and nine analytes frequently measured in routine tests. More than 100 laboratories certified for metrological traceability collaborated in the recruitment, sampling, and measurement of analytes for the establishment of RIs. No previous attempt has been made to establish RIs by such a large number of laboratories. The allowable limits of trueness and intermediate precision based on the JAMT criteria were applied to the reference values measured by these laboratories, and measured values within the allowance limits were used to establish RIs.

Methods: Reference individuals included 5748 healthy volunteers aged 18–65 years who were engaged in medical care-related work based on the CLSI guidelines. After secondary exclusion of individuals in whom abnormal values were detected in basic routine test items and adjustment for the distribution of age and gender, 3371 reference individuals were chosen in the parametric determination of RIs. Employing the three-level nested ANOVA, between-laboratory, -region, -sex, and -age variations were evaluated.

Results: No significant difference was noted in between-region variations in any item. Results of ANOVA revealed between-sex and -age variations in 14 and 15 analytes, respectively. Based on these results of variation, RIs were established with and without partition by sex.

Conclusions: Since no between-region variation was detected in reference values among accuracy-certified core laboratories, RIs applicable nationwide were established.

Published: April 2013

Abstract

Background: Excessive diagnostic phlebotomy in children and critically ill patients is a frequent phenomenon in many hospitals. However, little attention is paid to a single blood volume taken routinely everyday from thousands of patients worldwide. The objective of the present study was to assess the volume of a single blood sample draw for laboratory testing in a pediatric population in relation to child age and weight, number of diagnostic tests requested by physicians, laboratory needs, and size of collection tube.

Methods: A single blood volume draw for diagnostic tests was measured in 3136 consecutive routine samples taken from children (from 1 day to 18 years old) and placed into a Microvette® or regular sampling tubes. The serum excess was calculated by taking into account the serum volume needed for the requested number of tests and the dead volume of analyzer.

Results: A huge variation in blood volume draws between individual patients, regardless of the number of tests requested, has been observed. The number of blood samples placed into the microvette decreased with patients’ age, with 53.9% in children younger than 1 month old and 9.3% in children older than 12 years old. There was a clear-cut increase in the mean value of the blood volume draw with an increase in children’s age. Only 2% of children up to 3 years old had a blood volume draw >1 mL/kg body weight.

Conclusions: Each pediatric laboratory should have a clear-cut recommendation on the amount on blood volume necessary for the requested number of tests.

Published: April 2013

Abstract

Background: In order to minimize the influence of glycolysis on diabetes mellitus (DM) diagnostic tests, we have compared the behavior of citric/citrate, fluoride additives and gel-serum with plasma-heparin under careful preanalytical conditions. Subsequently, we compared the effectiveness of both fluoride and citric additives at different pre-centrifugation times. Finally, the influence of citric/citrate collection tube on diagnostic tests results was evaluated.

Methods: The first study of 80 voluntary patients assessed the glucose bias of citric/citrate, fluoride additive tubes and gel-serum tubes versus plasma-heparin tubes at several medical decision cut-offs (MDC). The second study performed with 72 volunteers evaluated additives, simulating transport times to the laboratory and centrifugation delay periods. Final evaluation compares the proportion of positive tests in total tests carried out in two different periods.

Results: When citric/citrate (n=79) and fluoride tubes (n=60) were compared with plasma-heparin under controlled preanalytical conditions, both met the bias specification for plasma glucose (±1.8%) at seven MDC. On the contrary, serum samples (n=15) did not meet it at five MDC. In the second study, differences in glucose values at distinct pre-centrifugation times were not statistically significant for citric/citrate tubes, but significant for fluoride tubes and also for comparison of fluoride and citric/citrate tubes. Hemolysis in fluoride tubes was higher. Citric/citrate tube implementation in our laboratory caused an increase in positive diagnostic tests that were only statistically significant for gestational diabetes mellitus (GDM) screening.

Conclusions: Citric/citrate additive tube is equivalent to plasma-heparin avoiding glycolysis completely and immediately under careful preanalytical conditions even with a 3-h delay in plasma separation. According to used MDC we have not statistically significantly increased the diagnoses of DM cases.
Prenatal diagnosis of cystic fibrosis: an experience of 181 cases
Authors: Tomaiuolo Rossella , Nardiello Paola , Martinelli Pasquale , Sacchetti Lucia , Salvatore Francesco , Castaldo Giuseppe 
Published: April 2013

AbstractBackground:The demand for prenatal diagnosis (PD) of cystic fibrosis (CF) is increasing.Methods:We performed pre-test multidisciplinary counselling for 192 couples at CF reproductive risk. In 11/192 (5.7%) cases PD was not performed mainly because counselling revealed a reproductive risk for atypical (mild) CF, while 181 PDs were performed in couples revealed at high risk for CF mainly because they already had a CF child (148/181, 81.8%) or had been identified through cascade screening (28/181, 15.5%).Results:In 167/181 (92.3%) cases (including two dichorionic twin pregnancies), PD was performed on chorionic villi, and in 14 on amniocyte DNA. Only 1/181 PD was unsuccessful. In all other cases, single tandem repeat analysis excluded maternal contamination, and PD was made within 7 days of sampling. In total 116/180 (64.4%) PDs were made with dot-blot analysis; 40 (22.2%) required gene sequencing; in 4/180 cases we tested the gene for large rearrangements; in 23/180 (12.8%) cases linkage analysis was necessary because parental mutation(s) were unknown. Forty-two out of 180 (23.3%) PDs revealed an affected foetus. All couples but one interrupted pregnancy. The first twin PD revealed the absence (1 foetus) and the presence of one mutation (the other foetus); the second twin PD revealed one parental mutation (1 foetus) and both parental mutations (the other foetus); the couple planned selective interruption.Conclusions:PD for CF should be performed in reference laboratories equipped for gene scanning and linkage analysis, with a multidisciplinary staff able to offer counselling to couples during all phases of PD.
On main conjectures in
non-commutative Iwasawa theory
and related conjectures
Authors: Burns David 
Published: April 2013

Abstract

The main conjecture of non-commutative Iwasawa theory is shown to be
equivalent, modulo an appropriate torsion hypothesis, to a family of
main conjectures over cyclotomic ℤ
p
-extensions together
with suitable compatibility relations between the associated abelian
p-adic L-functions. This result combines with techniques of
Ritter and Weiss and of Kakde to give a concrete strategy for
deducing main conjectures for (non-abelian) compact p-adic Lie
extensions of arbitrarily large rank from main conjectures in the
classical sense.

As a first application of this approach we combine it with a recent result of Ritter and Weiss to prove, modulo an appropriate vanishing hypothesis on μ-invariants, the main conjecture of non-commutative Iwasawa theory for Tate motives over compact p-adic Lie extensions of totally real number fields of arbitrarily large rank. We then also deduce several interesting consequences of this result concerning a range of related conjectures including special cases of the equivariant Tamagawa number conjecture.

On a notion of exactness for reduced free products of C*-algebras
Authors: Skoufranis Paul 
Published: April 2013

Abstract

We will study some modifications to the notion of an exact C*-algebra by replacing the minimal tensor product with the reduced free product. First we will demonstrate how the reduced free product of a short exact sequence of C*-algebras with another C*-algebra may be taken. It will then be demonstrated that this operation preserves exact sequences. We will also establish that adjoining arbitrary k-tuples of operators in a free way behaves well with respect to taking ultrapowers.
Operator biflatness of the L
1-algebras of compact quantum groups
Authors: Caspers Martijn , Lee Hun Hee , Ricard Éric 
Published: April 2013

Abstract

We prove that the L
1-algebra of any non-Kac type compact quantum group is not operator biflat. Since operator amenability implies operator biflatness, this result shows that any co-amenable, non-Kac type compact quantum group gives a counterexample to the conjecture that L
1(𝔾) is operator amenable if and only if 𝔾 is amenable and co-amenable for any locally compact quantum group 𝔾. The result also implies that the L
1-algebra of a locally compact quantum group is operator biprojective if and only if 𝔾 is compact and of Kac type.

Published: April 2013

Abstract

Aim: To report on a pregnant woman with peripartum cardiomyopathy 7 years after combination chemotherapy with doxorubicine and radiation of cancer of the left breast.

Case: A 35-year old primigravida who was treated 7 years earlier with cancer of the left breast (ympT1c, ypN0, cM0), according to a neoadjuvant study protocol (GeparTrio), was transferred to our unit due to HELLP syndome at 35+5 weeks. Symptoms of cardiopulmonary decompensation occurred shortly after cesarean delivery of a healthy newborn. The patient was admitted to cardiac intensive care and treated with oxygen, diuretics and ACE inhibitors. Maternal left ventricular ejection fraction recovered within a few weeks without any surgical interventions and remained stable within 1 year of follow-up.

Conclusion: The association between radical primary treatment of the left breast and life-threatening cardiac disease could possibly be provoked by pregnancy.
