Verbreitungsgrenzen südlicher Florenelemente in Mitteldeutschland
Authors: Meusel Hermann 
Published: August 2010

AbstractMitteldeutschland als Übergangsgebiet zwischen dem süddeutschen Berg‐ und Hügelland und dem norddeutschen Flachland ist durch das Ausklingen einer ganzen Reihe von Arten ausgezeichnet, deren Verbreitung von der submeridionalen bis in die südliche temperate Zone reicht. Als Beispiele werden nach ihrer Gesamtverbreitung verschiedene ökogeographische Gruppen behandelt: 1. Xerotherme Arten mit Beziehungen zur mediterran‐submediterranen Trockenwald‐ und Garrigue‐Vegetation und submediterran‐alpisch/dealpine Sippen. Die süd‐nördlich gestaffelten Grenzlinien dieser Arten sind durch das Großklima‐Gefälle bedingt und werden durch die besonderen Faktoren des lokalen Klimas, der Geländeformen und der Böden abgewandelt. Die meisten xerothermen südlichen Elemente der mitteldeutschen Flora häufen sich im nordfränkischen, thüringischen und osthessischen Kalkhügelland. 2. Kontinentale submediterran‐pontische Elemente sind im warmen Elbtal und vor allem im mitteldeutschen Trockengebiet (im Regenschatten des Harzes) verbreitet und erreichen hier vielfach ihre absolute Nordwestgrenze. 3. Von den submediterran‐mitteleuropäischen Bergpflanzen verdienen besonders diejenigen Arten Beachtung, die im Erzgebirge und im Thüringer Gebirge regelmäßig vorkommen, im Harz jedoch fehlen oder dieses Mittelgebirge nur in Vorposten erreichen. 4. Vertreter der süd‐mitteleuropäischen Laubwaldflora, die in Mitteldeutschland ihre Nordgrenze erreichen, sind a) als ozeanisch‐subozeanische Elemente im Werra‐Leine‐Weser‐Gebiet und im Thüringer Hügelland oder b) als subozeanisch‐(subkontinentale) Elemente im westsächsischen Hügelland konzentriert. Auch hier wirken Geländegestalt und Bodenverhältnisse modifizierend auf das mitteldeutsche Teilareal. 5. Abschließend werden submediterran‐atlantisch‐(zentraleuropäische) Sandpflanzen erwähnt, die sich vor allem in den Niederungen ausbreiten und deshalb in Mitteldeutschland trotz südlicher Herkunft Südwestgrenzen aufweisen. Von allen Verbreitungstypen werden Vertreter genannt, die in einem geschlossenen Areal bis in den mitteldeutschen Raum vordringen und solche, die hier nur Vorposten‐Areale erreichen.
Floral anatomy of two species of Swartzia and its bearing on its systematic position
Authors: Dhillon M. 
Published: August 2010

AbstractThe present investigation deals with the floral anatomy of two species of the genus Swartzia of the family Leguminosae. In Swartzia the vascular supply of sepals, petals and stamens arises independently from separate cycles of gaps. After the divergence of the vascular supply of the petals, a number of traces arise from third cycle of gaps and undergo repeated divisions to form a large number of traces, each one of which supplies a stamen. This is in contrast with Papilionaceous legumes which are either dihiate or unihiate, whereas Swartzia like members of Mimosoideae is trihiate. The implications of these obsevations on the systematic position of Swartzia have been discussed.

Gliederung, Verbreitung und Entstehung der Gattung Rhododendron – Eine Synthese aus botanischer, paläobotanischer und geologischer Sicht
Authors: Krutzsch Wilfried 
Published: August 2010

AbstractDie Kombination von Morphologie und Chorologie der subgenerischen Einheiten führt zu wichtigen Fragen bei der Bewertung der Untergliederung der Gattung. Ergänzung findet dieses in einer erstmalig vorgenommenen historischen Analyse der Gattung Rhododendron vor dem Hintergrund geowissenschaftlicher Daten (Paläoklimatologie, Paläogeographie, Paläochorologie, Paläofloristik, Paläoorographie etc.). Dies ergibt ein differenzierteres phylogenetisches Bild von der Entwicklung der Gattung, die, seit ca. 53 Mill. Jahren belegt, in mehreren Etappen in verschiedenen begrenzten Räumen und unter verschiedenen Klimaten erfolgt ist, d. h. während der verschiedenen Stufen des Tertiärs und Quartärs. Das heutige Mannigfaltigkeitszentrum in Südostasien ist dabei historisch‐geologisch betrachtet recht jung (ca. 10–15 Mill. Jahre) und als solches kein primäres, sondern ein durchaus sekundäres. Bis weit in das Alttertiär hinein war Südostasien noch ein Trokkengebiet. Die Differenzierung und Ausbreitung von sehr vielen der heutigen Arten Südostasiens (speziell die der Sektion Vireya) ist sehr jungen Datums (nur rund 1–5 Mill. Jahre alt). Als älteste Gruppen werden das Subgenus Hymenanthus, und zwar die Sektion/Subsektion Pontica, das Subgenus Pentanthera und Teile des Subgenus Rhododendron, Sekt./Subsekt. Rhododendron (Ferruginea) und Carolineana, resp. ihre Vorläuferformen, angesehen. Sie allein weisen auch heute noch in ihren Reliktarealen auf eine ursprüngliche nordtethyanische, laurasische, warm‐humide, extratropische laurophylle Gürtelflora des Alttertiärs hin, die sich vom westlichen Nordamerika über das östliche Nordamerika, Europa bis hin nach Mittelusien erstreckt hat. Dies ist der Ursprungs‐Florenbelt der Gattung Rhododendron. In diesem Belt fand im Eozän durch zonale klimatische Unterschiede die erste, wichtigste Differenzierung der Gattung statt. wobei die ursprünglich immergrünen, alepidoten Vertreter im Süden in die lepidoten und im Norden in die ersten sommergrünen, laubwerfenden alepidoten Typen aufspalten. Der alte zonale Vegetationsbelt zerfällt ab Oligozän in einen westlichen, mittleren (Europa/Vorderasien) und östlichen Teil. Fast alle folgenden Entwicklungsdifferenzierungen sind dann nur noch auf den östlichen Sektor. auf Südost‐ und Ostasien beschränkt, und sie alle sind jünger als Eozän. Diese Differenzierungsprozesse reichen bis hin zur Gegenwart. Die Besiedlung Nordostasiens und der arktischen Region ist im wesentlichen ein Phänomen des Quartärs. insbesondere des Holozäns.

Chemotaxonomical studies of the genus Salsola (Chenopodiaceae) in Egypt
Authors: Turki Z. A. 
Published: August 2010

AbstractAnalysis of protein, lipid and neutral sugars in nine species of Egyptian Salsola are carried out. In addition, fatty acids composition in closely related six species are determined by GLC. A remarkable chemical diversity between the different species is found.The protein level in S. imbricata subsp. imbricata is the highest of all studied species (392.7 mg/gm dry wt.) while the lowest is in S. schweinfurthii (83.6 mg/gm). The highest lipid content is detected in S. longifolia (32.2 mg/gm). The neutral sugar content is variable ranging from 15.3 mg/gm in S. schweinfurthii to 88.3 mg/gm in S. oppositifolia.The lipids of all species examined contain at least five different fatty acids. Oleic acid predominates in all species studied. Salsola inermis and S. imbricata subsp. gaetula are generally rich in fatty acids (both include eight fatty acids) while S. tetragona and S. incanescens have only five fatty acids.
WISP-1/CCN4 regulates osteogenesis by enhancing BMP-2 activity

Published: August 2010

Abstract
Wnt-induced secreted protein 1 (WISP-1/CCN4) is a member of the CCN family that is highly expressed in skeletal tissue and in osteoprogenitor cells induced to differentiate in vitro. To determine the function of WISP-1 during osteogeneis, osteogenic bone marrow stromal cells (BMSCs) were transduced with WISP-1 adenovirus (adWISP-1) in the presence or absence of bone morphogenetic protein 2 (BMP-2) adenovirus (adBMP-2). WISP-1 overexpression enhanced the ability of BMP-2 to direct BMSCs toward osteogenic differentiation and appeared to work by stimulating Smad-1/5/8 phosphorylation and activation. The ability of WISP-1 to enhance BMP-2 activity also was shown in vivo using an ectopic osteogenesis assay with BMSCs transduced with WISP-1, BMP-2, or both. When BMSCs were infected with lentivirus containing human WISP1 shRNA, they formed less bone in vivo and were less responsive to BMP-2, confirming that WISP-1 and BMP-2 have a functional interaction. Immunoprecipitation (IP) and Western blot analysis showed that WISP-1 bound directly to BMP-2 and showed that WISP-1 increased BMP-2 binding to hBMSCs in a dose-dependent fashion. To understand how WISP-1 enhanced BMP-2 signaling, the influence of WISP-1 on integrin expression was analyzed. WISP-1 induced the mRNA and protein levels of α5-integrin and, further, was found to bind to it. Antibody-blocking experiments showed that the BMP-2 binding to BMSCs that was enhanced by WISP-1 was completely neutralized by treatment with anti-integrin α5β1 antibody. Pilot studies and the use of transgenic mice that overexpressed human WISP-1 in preosteoblasts had increased bone mineral density (BMD), trabecular thickness, and bone volume (BV/TV) over wild-type controls, supporting observations using human osteoprogenitors that WISP-1 has a positive influence on osteogenesis in vivo. In conclusion, these studies show, for the first time, that WISP-1 has a positive influence on bone cell differentiation and function and may work by enhancing the effects of BMP-2 to increase osteogenesis through a mechanism potentially involving binding to integrin α5β1. © 2011 American Society for Bone and Mineral Research.
The microtubule cytoskeleton acts as a key downstream effector of neurotransmitter signaling
Authors: Gardiner John , Overall Robyn , Marc Jan 
Published: August 2010

AbstractMicrotubules are well known to play a key role in the trafficking of neurotransmitters to the synapse. However, less attention has been paid to their role as downstream effectors of neurotransmitter signaling in the target neuron. Here, we show that neurotransmitter‐based signaling to the microtubule cytoskeleton regulates downstream microtubule function through several mechanisms. These include tubulin posttranslational modification, binding of microtubule‐associated proteins, release of microtubule‐interacting second messenger molecules, and regulation of tubulin expression levels. We review the evidence for neurotransmitter regulation of the microtubule cytoskeleton, focusing on the neurotransmitters serotonin, melatonin, dopamine, glutamate, glycine, and acetylcholine. Some evidence suggests that microtubules may even play a more direct role in propagating action potentials through conductance of electric current. In turn, there is evidence for the regulation of neurotransmission by the microtubule cytoskeleton. Synapse, 2010. © 2010 Wiley‐Liss, Inc.
Differential developmental trajectories for CB1 cannabinoid receptor expression in limbic/associative and sensorimotor cortical areas
Authors: Heng Lijun , Beverley Joel A. , Steiner Heinz , Tseng Kuei Y. 
Published: August 2010

AbstractCannabis use during adolescence is associated with an increased risk for schizophrenia and other disorders. The neuronal basis is unclear, but prefrontal cortical mechanisms have been implicated. Here, we investigated developmental changes in the endocannabinoid system by assessing expression and function of the CB1 cannabinoid receptor in prefrontal and other cortical areas in juvenile (postnatal day 25, P25), adolescent (P40), and adult (P70) rats. Overall, the expression of CB1 receptors in the cortex is highest in juveniles and drops thereafter toward adult levels. However, CB1 receptor expression follows distinct developmental trajectories in different cortical areas. The most pronounced and progressive decrease in CB1 expression was observed in medial prefrontal and other limbic/associative regions. In contrast, major changes in sensorimotor cortices occurred only after P40. We also assessed electrophysiological measures of CB1 receptor function and found that CB1‐dependent inhibition of synaptic transmission in the prefrontal cortex follows the same developmental trajectory as observed for receptor expression. Together, these findings indicate that CB1 receptor‐mediated signaling decreases during development but is differentially regulated in limbic/associative vs. sensorimotor systems. Therefore, cannabis use during adolescence likely differentially affects limbic/associative and sensorimotor cortical circuits. Synapse, 2011. © 2010 Wiley‐Liss, Inc.
Differential effects of stress on [11C]raclopride and [11C]MNPA binding to striatal D2/D3 dopamine receptors: A PET study in conscious monkeys
Authors: Tsukada Hideo , Ohba Hiroyuki , Nishiyama Shingo , Kakiuchi Takeharu 
Published: August 2010

AbstractIt has been reported that stress and facilitation of dopamine neuronal system are closely related. In the present study, the effects of stress on the binding of antagonist‐based [11C]raclopride and agonist‐based (R)‐2‐CH3O‐N‐n‐ propylnorapomorphine ([11C]MNPA) to D2/D3 receptors were evaluated in the striatum of conscious monkey brain. The stress state assessed from plasma cortisol level was negatively correlated with [11C]raclopride binding as expected. It was noteworthy that [11C]MNPA binding exhibited a positive correlation with stress state; thus, the animals with higher cortisol levels showed higher binding to D2/D3 receptors.

AbstractProtease production fromDuddingtonia flagrans(isolate AC001) was optimized and the larvicidal activity of the enzymatic extract was evaluated on infective horse cyathostomin larvae (L3).Duddingtonia flagranswas grown in liquid medium with eight different variables: glucose, casein, bibasic potassium phosphate (K2HPO4), magnesium sulphate (MgSO4), zinc sulphate (ZnSO4), ferrous sulphate (FeSO4), copper sulphate (CuSO4) and temperature. The Plackett–Burman analysis showed a significant influence of MgSO4, CuSO4and casein (P < 0.05) on protease production byD. flagransin liquid medium. Central composite design indicated that the highest proteolytic activity was 39.56 U/ml as a function of the concentrations of casein (18.409 g/l), MgSO4(0.10 g/l) and CuSO4(0.50 mg/l). A significant difference (P < 0.01) was found for the larval number between the treated and control groups at the end of the experiment. A reduction of 95.46% in the number of free-living larvae was found in the treated group compared with the control. The results of this study suggest that protease production byD. flagrans(AC001) in liquid medium was optimized by MgSO4, CuSO4and casein, showing that the optimized enzymatic extract exerted larvicidal activity on cyathostomins and therefore may contribute to large-scale industrial production.
On backward self-similar blow-up solutions to a supercritical semilinear heat equation
Authors: Mizoguchi Noriko 
Published: August 2010

We are concerned with a Cauchy problem for the semilinear heat equationthen u is called a backward self-similar solution blowing up at t = T. Let pS and pL be the Sobolev and the Lepin exponents, respectively. It was shown by Mizoguchi (J. Funct. Analysis257 (2009), 2911–2937) that k ≡ (p − 1)−1/(p−1) is a unique regular radial solution of (P) if p > pL. We prove that it remains valid for p = pL. We also show the uniqueness of singular radial solution of (P) for p > pS. These imply that the structure of radial backward self-similar blow-up solutions is quite simple for p ≥ pL.

AbstractThe goal of the present study was to evaluate the diagnostic discriminability of three different global scores for the German version of the Consortium to Establish a Registry on Alzheimer’s Disease-Neuropsychological Assessment Battery (CERAD-NAB). The CERAD-NAB was administered to 1100 healthy control participants [NC; Mini-Mental State Examination (MMSE) mean = 28.9] and 352 patients with very mild Alzheimer’s disease (AD; MMSE mean = 26.1) at baseline and subsets of participants at follow-up an average of 2.4 (NC) and 1.2 (AD) years later. We calculated the following global scores: Chandler et al.’s (2005) score (summed raw scores), logistic regression on principal components analysis scores (PCA-LR), and logistic regression on demographically corrected CERAD-NAB variables (LR). Correct classification rates (CCR) were compared with areas under the receiver operating characteristics curves (AUC). The CCR of the LR score (AUC = .976) exceeded that of the PCA-LR, while the PCA-LR (AUC = .968) and Chandler (AUC = .968) scores performed comparably. Retest data improved the CCR of the PCA-LR and Chandler (trend) scores. Thus, for the German CERAD-NAB, Chandler et al.’s total score provided an effective global measure of cognitive functioning, whereby the inclusion of retest data tended to improve correct classification of individual cases.

Autonomie im Pflegeheim – Konzeptionelle Überlegungen zu Selbstbestimmung und Handlungsfähigkeit anhand eines Modells
Authors: Wulff Ines , Kalinowski Sonja , Dräger Dagmar 
Published: August 2010

Autonomie ist ein äußerst komplexer, zentraler philosophischer Begriff, welcher unter anderem in ethischen Fragestellungen auch im pflegerischen Kontext seine praktische Anwendung findet. Es kann derzeit nicht von einer einheitlichen Definition von Autonomie ausgegangen werden. Aus Sicht der Autorinnen sind Selbstbestimmung und Handlungsfähigkeit zentrale Aspekte von Autonomie. Während einige Erkenntnisse zu Autonomie im Alter vorliegen, ist zu Autonomie von Pflegeheimbewohnern/-bewohnerinnen sowie wichtigen Einflussfaktoren im Setting Pflegeheim noch wenig bekannt. Ziel dieses Artikels ist es, zu einem besseren Verständnis von Autonomie von Pflegeheimbewohner/-innen beizutragen. Aufgrund des hohen Anteils von Menschen mit kognitiven Beeinträchtigungen in Pflegeheimen spielt insbesondere diese Population bei der Konzeptionalisierung von Autonomie eine wichtige Rolle. Unterschiedliche bestehende Ansätze und die im Rahmen des PAiN-Projekts (Pain and Autonomy in the Nursing Home) entwickelten Perspektiven haben zur Erarbeitung eines eigenen konzeptionellen Verständnisses von Autonomie geführt. Das im interdisziplinären Projektteam entwickelte Modell zu «Bestimmungsfaktoren von Autonomie» gründet sich auf theoretischen und diskursiven Auseinandersetzungen und fokussiert Selbstbestimmung und Handlungsfähigkeit der Bewohner/-innen im Kontext des Setting Pflegeheim. Dieser Konzeption wesentlich ist die unterschiedliche Ausprägungsmöglichkeit von Autonomie sowohl hinsichtlich Selbstwahrnehmung als auch hinsichtlich der Zuschreibung von Autonomie.
Modified Therapeutic Community for Co-Occurring Disorders: Single Investigator Meta Analysis
Authors: Sacks Stanley , McKendrick Karen , Sacks JoAnn Y. , Cleland Charles M. 
Published: August 2010

This paper presents the results of a meta-analysis for a single investigator examining the effectiveness of the modified therapeutic community (MTC) for clients with co-occurring substance use and mental disorders (COD). The flexibility and utility of meta-analytic tools are described, although their application in this context is atypical. The analysis includes 4 comparisons from 3 studies (retrieved N = 569) for various groups of clients with COD (homeless persons, offenders, and outpatients) in substance abuse treatment, comparing clients assigned either to an MTC or a control condition of standard services. An additional study is included in a series of sensitivity tests. The overall findings increase the research base of support for the MTC program for clients with COD, as results of the meta-analysis indicate significant MTC treatment effects for 5 of the 6 outcome domains across the 4 comparisons. Limitations of the approach are discussed. Independent replications, clinical trials, multiple outcome domains, and additional meta-analyses should be emphasized in future research. Given the need for research-based approaches, program and policy planners should consider the MTC when designing programs for co-occurring disorders.

This work presents the results of the attachment of Qdot 655 ITK

TM
amino (PEG) quantum dots (QDs) (Invitrogen) and CdTe QDs (provided by Institute of Materials Science, VAST) to HER2 (Human Epidermal growth factor Receptor 2) specific phage antibodies (Abs) (provided by Institute of Biotechnology, VAST) in solution. The QDs were attached to the phage display specific HER2 Abs to form a complex QD–Ab. The QDs and complex QD–Ab were characterized by UV-VIS spectroscopy, transmission electron microscopy (TEM) and fluorescence microscopy. The fluorescence images show the QDs conjugated to the phage. Due to the QDs attaching to the surface, the phage dimensions were amplified, so its shape could be observed by optical microscopy. The complex QD–Ab was stable and lasted for a month. The results illustrate the value of the HER2 phage–QD complex as a cancer detection platform.
Copper thin film for RFID UHF antenna on flexible
substrate

Published: August 2010

Abstract
A process flow using photolithography and sputtering was studied for copper antenna
fabrication on thin poly(ethylene terephthalate) (PET) substrate. The lift-off route
was chosen for its flexibility at laboratory scale. It was clarified that the
cleaning of PET is an important step that necessitates mild oxygen plasma etching.
Then copper is sputter deposited after photolithographic definition of the antenna.
Care is necessary since PET, as a very flexible substrate, is temperature sensitive.
The temperature increase generated by the impact of deposited copper should be
maintained below the glass transition temperature of the polymer to avoid detrimental
deformation. dc power of 40 to 50 W was found to be the maximum possible sputtering
power for commercial PET. It was found that the resistivity of the thin film is below
two times the bulk resistivity of copper for a deposition pressure below
4×10−3
mbar and thickness above 450 nm. These results
enable the reliable fabrication of copper RFID UHF antennae on a PET substrate for
further testing of new tag designs. The present paper summarizes the effort to test
new designs of antennae for RadioFrequency IDentification (RFID) Ultra High Frequency
(UHF) tags, for use in various applications (e.g. object tracking and environment
monitoring) in Vietnam.
