Wirkungen einer physikalischen Stimulierung der spontanen arteriolären Vasomotion bei Rehabilitanden unterschiedlichen Alters
Authors: Klopp Rainer Christian , Niemer Wolfgang , Schulz Jörg 
Published: August 2013

Zusammenfassung
An zwei Stichproben aus Rehabilitanden unterschiedlicher Alters-gruppen (~38 Jahre und ~51 Jahre) wurde im Rahmen einer placebokontrollierten Untersuchungsreihe anhand repräsentativer Funktionsmerkmale der Mikrozirkulation der komplementär-thera-peutische Erfolg einer Zusatzbehandlung zur biorhythmisch definier-ten physikalischen Vasomotionsstimulation ermittelt. Als Ergebnis zeigte sich, dass bei älteren Rehabilitanden die Beträge der mikrozirkulatorischen Merkmaländerungen größer sind als bei jüngeren Rehabilitanden, sie klingen jedoch nach Beendigung der Zusatzbehandlung rascher als bei diesen ab.

Published: August 2013

AbstractBlends of isotactic polypropylene (iPP) and high density polyethylene (HDPE), with and without compatibilizers and with different organoclay amounts (1%, 3%, and 5%), were systematically investigated to assess the effect of the additives on the crystallinity of the blends, as well as the correlation between the microhardness,Hand the Young’s modulusE. The compatibilizers used were: maleic anhydride grafted styrene ethylene butadiene styrene (SEBS-g-MAH), maleic anhydride grafted polyethylene (PE-g-MAH), maleic anhydride grafted polypropylene (PP-g-MAH), ethylene propylene diene monomer (EPDM), and maleic anhydride grafted EPDM (EPDM-g-MAH). The thermal properties and crystallization behavior were determined by differential scanning calorimetry (DSC) and wide angle X-ray scattering (WAXS). Macro- and micromechanical properties were also investigated. The results obtained showed that the addition of clay slightly increases the crystallinityαWAXSof the blends. However, the hardnessHdecreases enormously only by adding 1 wt% of clay. With higher clay amounts,Hincreases again. The relationship between the Young’s modulusEand the hardnessHfor all the studied blends was found to be somewhat higher than the one obtained for polyethylene (PE) samples with different morphologies.
Possibility of amoebas' aggregation in finite time
Authors: Hilmi Saïd , Ziti Chérif 
Published: August 2013

Abstract
The dynamic of amoebas in favorable circumstances is modeled by a nonlinear system of Partial Differential Equations arising in chemotaxis. The competition between different parameters of this system plays a major role in the process of aggregation. Throughout this paper, we prove the existence of self-similar solutions that blow up in finite time in a dimensional space and under specific circumstances depending upon the position of those parameters.

Authors: Wu Chang-Qun , Hao Yan 
Published: August 2013

Abstract In this paper, the problem of modifying Halpern iteration for approximating a common fixed point of a family of asymptotically quasi- ∅-nonexpansive mappings is considered. Strong convergence theorems are established in a uniformly smooth and strictly convex Banach space which also enjoys the Kadec-Klee property. The results presented in this paper mainly improve the corresponding results announced in [Y.J. Cho, X. Qin, S.M. Kang, Strong convergence of the modified Halpern- type iterative algorithms in Banach spaces, An. Stiint. Univ. Ovidius Constanta Ser. Mat. 17 (2009) 51-68].
Anger Makes You Feel Stronger: The Positive Influence of Trait Anger in a Real-Life Experiment
Authors: Tibubos Ana Nanette , Schnell Kerstin , Rohrmann Sonja 
Published: August 2013

Abstract
Although anger as a negative emotion is associated with unpleasantness, recent research on anger highlights its motivational effect. The present study tested whether individuals experience both, an unpleasant and an activating affect, after real-life provocations. Results revealed that an anger situation evoked not only typical subjective and cardiovascular anger reactions but also a sense of strength, which is a positive affect. A comparison of participants with low versus high anger disposition according to the STAXI-2 at baseline, treatment, and recovery showed that participants with high trait anger consistently scored higher in subjective ratings of feeling strong than their counterparts did. Moreover, we found a larger and longer lasting effect of feeling strong than feeling angry after an anger treatment. Thus, differences in anger disposition influence the positive correlation between trait anger and positive affect.
Test and Math Anxiety: A Validation of the German Test Anxiety Questionnaire
Authors: Schnell Kerstin , Tibubos Ana Nanette , Rohrmann Sonja , Hodapp Volker 
Published: August 2013

Abstract
The present study investigated the construct validity of the Test Anxiety Questionnaire (Prüfungsangstfragebogen PAF; Hodapp, Rohrmann, & Ringeisen, 2011), a revised and shortened version of the German Test Anxiety Inventory (TAI-G), by comparing it with math anxiety. A sample of German fifth- and sixth-grade students (N = 79; 61 % male) was analyzed. Math anxiety was measured by a German adaptation of the Math Anxiety Questionnaire (Fragebogen für Rechenangst FRA; Krinzinger et al., 2007). A significant but moderate correlation between test anxiety and math anxiety was found. In regression analyses, math anxiety predicted math performance whereas test anxiety explained additional variance for both math and overall performance. It can be concluded that math and test anxiety have overlaps, but do not constitute the same construct. Thus, the results support the construct validity of the PAF indicating its usefulness in practical application.

Published: August 2013

×One of key questions in breeding for organic agriculture is about most appropriate selection environment. A successful man-made cereal species, triticale (Triticosecale Wittm. ex A. Camus.) - is very suitable for growing in organic crop management systems but little research has been conducted on breeding triticale for organic agriculture. Field trials were carried out in Priekuïi during 2009-2012. One hundred F4 winter triticale lines were sown in conventionally and organically managed fields. Selection of the approximately ten best lines in each environment, according to breeders’ opinion with respect to suitability for organic conditions, was made. The selected lines were compared in both organic and conventional fields. The study did not show that there was a need to create varieties for organic farming by selection of triticale in the initial generations in organic fields.
Changes in Strength, Endurance, and Fatigue During a Resistance-Training Program for the Triceps Brachii Muscle
Authors: Gacesa Jelena Z. Popadic , Klasnja Aleksandar V. , Grujic Nikola G. 
Published: August 2013

Context:
As a result of the adaptation process, some functional properties show different functions over time during strength training. Muscle strength and fatigue may show different adaptation patterns in reaching the improvement plateau after several weeks of training.

Objective:
To follow muscle endurance and fatigue values during resistance training of the elbow extensors in young nonathletes.

Design:
Descriptive laboratory study.

Setting:
Controlled laboratory.

Patients or Other Participants:
Nineteen healthy young nonathletes (age = 21.0 ± 1.1 years; body mass index = 25.2 ± 2.9 kg/m2).

Intervention(s):
Triceps brachii resistance training was performed on the isoacceleration dynamometer for 10 weeks (frequency = 5 times a week, 5 sets of 10 maximal elbow extensions, 1-minute resting period between sets).

Main Outcome Measure(s):
Measurements of endurance strength and fatigability were conducted using the same equipment, and endurance strength (ES), fatigue rate (FR), and decrease in strength (DS) were defined.

Results:
All measured values for triceps brachii strength changed after training (ES increased by 57%, FR decreased by 68%, and DS improved by 59%; P &lt; .001). No correlation was found between ES and the fatigability values—FR and DS (r2 = 0.37 for FR and r2 = 0.04 for DS; P &gt; .05). The FR and DS trends showed specific functions, which reached a plateau after 4 weeks of training, and we found no further weekly changes in these values as the training continued. As an adaptation to exercise, ES showed a continuous, yet not linear, increase.

Conclusions:
Fatigability in the triceps brachii decreased in the first 4 weeks of training. After that period, muscle functional properties improved as a result of increased endurance.

AbstractLoss‐of‐function mutations of NSD1 and 5q35 microdeletions encompassing NSD1 are a major cause of Sotos syndrome (Sos), which is characterized by overgrowth, macrocephaly, characteristic facies, and variable intellectual disability (ID). Microduplications of 5q35.2–q35.3 including NSD1 have been reported in only five patients so far and described clinically as a reversed Sos resulting from a hypothetical gene dosage effect of NSD1. Here, we report on nine patients from five families with interstitial duplication 5q35 including NSD1 detected by molecular karyotyping. The clinical features of all 14 individuals are reviewed. Patients with microduplications including NSD1 appear to have a consistent phenotype consisting of short stature, microcephaly, learning disability or mild to moderate ID, and distinctive facial features comprising periorbital fullness, short palpebral fissures, a long nose with broad or long nasal tip, a smooth philtrum and a thin upper lip vermilion. Behavioral problems, ocular and minor hand anomalies may be associated. Based on our findings, we discuss the possible etiology and conclude that it is possible, but so far unproven, that a gene dosage effect of NSD1 may be the major cause. © 2013 Wiley Periodicals, Inc.

AbstractThe acrofacial dysostosis syndromes, which are characterized by malformations of the craniofacial region and limbs, are a clinically heterogeneous group of disorders. Based primarily on the of the pattern of limb defects two major groups have emerged: Nager syndrome with predominantly preaxial malformations plus mandibulofacial dysostosis (severe micrognathia and malar hypoplasia) and Miller syndrome with postaxial malformations plus mandibulofacial dysostosis. Among these syndromes, Nager syndrome is a rare condition but the most common form of acrofacial dysostosis. Most cases are sporadic, while autosomal dominant and autosomal recessive inheritance patterns have been reported. Recently, heterozygous mutations in the SF3B4 gene on chromosome 1q12–q21 were found to be responsible for a subset of sporadic and autosomal dominant cases. We present a female infant born to consanguineous parents with craniofacial features resembling Nager syndrome and a unilateral preaxial limb malformation. Mutation analysis of coding exons of SF3B4 did not identify any mutations. This couple also had a deceased child who had similar clinical features. We conclude that, the presence of consanguinity and absence of mutation in SF3B4, provides evidence in support of a recessive form of Nager syndrome. © 2013 Wiley Periodicals, Inc.

Published: August 2013

AbstractAdolescents and young adults with Down syndrome (DS) sometimes experience new‐onset mood disorder and decline in adaptive skills. The clinical phenomenon is poorly characterized and its pathogenesis is not understood. The possible contribution of obstructive sleep apnea syndrome (OSAS) to this phenomenon has not been studied. Subjects were ascertained as a convenience sample through our clinic for persons with DS and medical or mental health concerns between 2004 and 2009. When mood symptoms were present an axis I diagnosis was made using DSM‐IV‐R criteria. Subjects without an axis I diagnosis served as controls. The Reiss scales for children's dual diagnosis and the aberrant behavior checklist (ABC) were completed by caretakers. Twenty‐eight cases meeting criteria for major depressive episode (MDE) and nine controls without psychopathology were referred for overnight polysomnography (PSG). Functional decline was reported in 19 (68%) of cases with MDE, but none of the controls. Twenty‐four (86%) cases had OSAS compared with only 4 (44%) of controls. Moderate–severe OSAS was present in 15 (54%) of cases compared to only 1 (11%) of controls. Intermittent sleep‐associated hypoxia and REM sleep deficits were also more frequent in cases. Across all subjects, prior tonsillectomy was not related to the presence or absence of OSAS. Our findings suggest that OSAS may be a common co‐morbidity in adolescents and younger adults with DS and depression. Recognition of this association maybe critical to understanding the pathogenesis and management of mood‐related disorders, and functional decline in affected individuals. © 2013 Wiley Periodicals, Inc.

AbstractKabuki syndrome is a congenital anomaly syndrome characterized by developmental delay, intellectual disability, specific facial features including long palpebral fissures and ectropion of the lateral third of the lower eyelids, prominent digit pads, and skeletal and visceral abnormalities. Mutations in MLL2 and KDM6A cause Kabuki syndrome. We screened 81 individuals with Kabuki syndrome for mutations in these genes by conventional methods (n = 58) and/or targeted resequencing (n = 45) or whole exome sequencing (n = 5). We identified a mutation in MLL2 or KDM6A in 50 (61.7%) and 5 (6.2%) cases, respectively. Thirty‐five MLL2 mutations and two KDM6A mutations were novel. Non‐protein truncating‐type MLL2 mutations were mainly located around functional domains, while truncating‐type mutations were scattered through the entire coding region. The facial features of patients in the MLL2 truncating‐type mutation group were typical based on those of the 10 originally reported patients with Kabuki syndrome; those of the other groups were less typical. High arched eyebrows, short fifth finger, and hypotonia in infancy were more frequent in the MLL2 mutation group than in the KDM6A mutation group. Short stature and postnatal growth retardation were observed in all individuals with KDM6A mutations, but in only half of the group with MLL2 mutations. © 2013 Wiley Periodicals, Inc.

Published: August 2013

AbstractSmith–Lemli–Opitz syndrome (SLOS) is a neurodevelopmental disorder caused by inborn errors of cholesterol metabolism resulting from mutations in 7‐dehydrocholesterol reductase (DHCR7). There are only a few studies describing the brain imaging findings in SLOS. This study examines the prevalence of magnetic resonance imaging (MRI) abnormalities in the largest cohort of patients with SLOS to date. Fifty‐five individuals with SLOS (27 M, 28 F) between age 0.17 years and 25.4 years (mean = 6.2, SD = 5.8) received a total of 173 brain MRI scans (mean = 3.1 per subject) on a 1.5T GE scanner between September 1998 and December 2003, or on a 3T Philips scanner between October 2010 and September 2012; all exams were performed at the Clinical Center of the National Institutes of Health. We performed a retrospective review of these imaging studies for both major and minor brain anomalies. Aberrant MRI findings were observed in 53 of 55 (96%) SLOS patients, with abnormalities of the septum pellucidum the most frequent (42/55, 76%) finding. Abnormalities of the corpus callosum were found in 38 of 55 (69%) patients. Other findings included cerebral atrophy, cerebellar atrophy, colpocephaly, white matter lesions, arachnoid cysts, Dandy–Walker variant, and type I Chiari malformation. Significant correlations were observed when comparing MRI findings with sterol levels and somatic malformations. Individuals with SLOS commonly have anomalies involving the midline and para‐midline structures of the brain. Further studies are required to examine the relationship between structural brain abnormalities and neurodevelopmental disability in SLOS. © 2013 Wiley Periodicals, Inc.
Preparation of chitosan‐g‐poly(acrylamide)/montmorillonite superabsorbent polymer composites: Studies on swelling, thermal, and antibacterial properties

Published: August 2013

ABSTRACTSuperabsorbent composites based on chitosan‐g‐poly(acrylamide) and montorillonite (CTS‐g‐PAAm/MMT) were synthesized through in situ radical polymerization by grafting of crosslinked acrylamide onto chitosan backbone in presence of MMT at different contents. The formation of the grafted network was confirmed by attenuated total reflectance Fourier transform infrared spectroscopy (ATR‐FTIR), thermogravimetric analysis (TGA), and differential scanning calorimetery (DSC). The obtained porous structure was observed by scanning electron microscope (SEM). The presence of clay and its interaction with chitosan‐g‐poly(acrylamide) (CTS‐g‐PAAm) matrix was evidenced by ATR‐FTIR analysis. The morphology was investigated by both X‐ray diffraction (XRD) and SEM analyses. It was suggested the formation of mostly exfoliated structures with more porous structures. Besides, the thermal stability of these composites, observed by TGA analysis, was slightly affected by the clay loading as compared to the matrix. These hydrogel composites were also hydrolyzed to achieve anionic hydrogels with ampholytic properties. Swelling behaviors were examined in doubly distilled water, 0.9 wt % NaCl solution and buffer solutions. The water absorbency of all superabsorbent composites was enhanced by adding clay, where the maximum was reached at 5 wt % of MMT. Their hydrolysis has not only greatly optimized their absorption capacity but also improved their swelling rate and salt‐resistant ability. The hydrolyzed superabsorbent showed better pH‐sensitivity than the unhydrolyzed counterparts. The results of the antibacterial activity of these superabsorbents composites against Staphylococcus aureus (S. aureus) and Escherichia coli (E. coli), assayed by the inhibitory zone tests, have showed moderate inhibition of the bacteria growth. © 2013 Wiley Periodicals, Inc.

Co‐extruded polymeric films for gas separation membranes
Authors: Armstrong Shannon R. , Offord Grant T. , Paul Donald R. , Freeman Benny D. , Hiltner Anne , Baer Eric 
Published: August 2013

ABSTRACTIn recent years, gas separation has become an important step in many production process streams and part of final products. Through the use of melt co‐extrusion and subsequent orientation methods, gas separation membranes were produced entirely without the use of solvents, upon which current methods are highly dependent. Symmetric three layer membranes were produced using poly(ether‐block‐amide) (PEBA) copolymers, which serve as a selective material that exhibits a high CO2 permeability relative to O2. Thin layers of PEBA are supported by a polypropylene (PP) layer that is made porous through the use of two methods: (1) inorganic fillers or (2) crystal phase transformation. Two membrane systems, PEBA/(PP + CaCO3) and PEBA/β‐PP, maintained a high CO2/O2 selectivity while exhibiting reduced permeability. Incorporation of an annealing step either before or after orientation improves the membrane gas flux by 50 to 100%. The improvement in gas flux was a result of either elimination of strain induced crystallinity, which increases the selective layer permeability, or improvement of the PP crystal structure, which may increase pore size in the porous support layer. © 2013 Wiley Periodicals, Inc.

Influence of molecular orientation direction on the in‐plane thermal conductivity of polymer/hexagonal boron nitride composites
Authors: Yoshihara Shusuke , Sakaguchi Masashi , Matsumoto Kazuaki , Tokita Masatoshi , Watanabe Junji 
Published: August 2013

ABSTRACTThe effect of the molecular orientation direction of a polymer matrix on the in‐plane thermal conductivity (TC) of injection‐molded polymer/hexagonal boron nitride (h‐BN) composites is investigated. In this system, the h‐BN platelets align in the in‐plane direction owing to injection shear flow. Three molecular orientations (perpendicular, random, and parallel to the h‐BN plane) are achieved using liquid crystalline polyesters and the in‐plane TCs are compared. Although a parallel orientation of the polymer chains provides the highest TC of the matrix in the injection direction, the TC of the composites is the lowest of the three systems for this orientation. The highest in‐plane TC is found in the perpendicularly oriented system, irrespective of the in‐plane direction. These results reveal that perpendicularly oriented molecular chains serve as effective heat paths between h‐BN platelets that are arranged one above the other, and consequently, a continuous thermal network is created in the in‐plane direction. © 2013 Wiley Periodicals, Inc.
