Induction of ornithine decarboxylase activity in hairless rat epidermis as a pharmacological model: validation of the animal model
Authors: Bouclier M. , Jomard A. , Kail N. , Shroot B. , Hensby C.
Published: July 2007

We use a mutant hairless Sprague Davvley rat to evaluate the capacity of retinoids to inhibit the epidermal ornithine decarboxylase activity induced by sellotape stripping. In order to minimize the variability introduced by the animals in our model we decided to validate the hairless rats used.

A number of animal parameters were examined using a single lot of 50 males and 50 females aged from 4 to 11 weeks and acclimatized to laboratory conditions. The body weight growth curves were established. Nude animals present two periods of hair growth, the first at 6-7 weeks and the second at about 10-11 weeks. Hair development is more pronounced in males. No histological change was observed in the stratum corneum but an increase in epidermal thickness was noted in males aged 9 weeks. Removal of the stratum corneum by sellotape stripping was more effective and reproducible in the females, as determined histologically. Sellotape-stripping induction of ornithine decarboxylase in the epidermis was higher in rats aged 5-6 weeks and reached a plateau in animals aged 6-12 weeks. Individual variations obtained were lower in females (about 5%-10% in females and 10%-20% in males).

The present research suggests that female rats aged about 8 weeks provide maximum reproducibility of response and ease of use.
Reconstructing evidence-based practice: an investigation of three conceptualisations of EBP
Authors: Olsson Tina M.
Published: July 2007

English

This article uses programme theory reconstruction to investigate three conceptualisations of evidence-based practice (EBP). The first two are taken directly from the literature and contrasted with a third taken from a relevant policy programme. The article argues that ‘evidence-based practice’ is not a homogeneous concept, and that interested parties within research, practice and policy may not have a shared vision of EBP even though they may use the same terminology. It is important for the successful implementation of EBP within practice and policy that there is a clear understanding of what EBP is and how EBP is supposed to work if research, policy and practice are to work together toward common goals.

Published: July 2007

Only 20–25% of families screened for BRCA1/2 mutations are found positive. Because only a positive result is informative, we studied the role of BRCA1/2 immunohistochemistry as an additional method for patient selection. From 53 high-risk-affected probands, 18 (34%) had available paraffin blocks of their tumors and were selected for this study. Mutation screening was done by conformation-sensitive gel electrophoresis and multiplex ligation-dependent probe amplification. For immunohistochemistry, 21 neoplastic specimens (15 breast carcinomas, 5 ovary neoplasms, and 1 rectal adenocarcinoma) were analyzed with BRCA1 (monoclonal antibody, Ab-1, oncogene) and BRCA2 (polyclonal antibody, Ab-2, oncogene) antibodies. Absence of the BRCA1 protein was confirmed in negative tumors by Western blotting. Seven patients were positive for BRCA1/2 mutations: 5 for BRCA1 and 2 for BRCA2. Four out of five positive patients had tumors negative for BRCA1 immunostaining, and the remaining 13 BRCA1-negative patients had positive BRCA1 immunostaining in all tumor samples. Sensitivity to predict for BRCA1 mutation carriers was 80%, and specificity was 100%, with a positive predictive value of 100% and a negative predictive value of 93%. This correlation was statistically significant ( p=0.001). No correlation was observed for BRCA2. If larger studies confirm these results, high-risk patients with BRCA1-negative tumors should be screened first for this gene.
Comparative gross morphology of the digestive tract in ten Didelphidae marsupial species
Authors: Santori R.T. , Moraes D. Astua De , Cerqueira Rui
Published: July 2007

Natural diets of Didelphidae species vary in the amounts of invertebrates, fruits
and small vertebrates eaten. We investigated the digestive morphology of ten
species of didelphid marsupials varying in food habits. The purpose was to
describe and to compare the shape and relative size of the digestive tract portions
among species studied and relate them to food habits. The form of the
gastrointestinal tract in this family is simple, with a unilocular stomach, small
intestine, large intestine and caecum. Caluromys philander was the species with
highest association between digestive tract measurements and its frugivorous
habits. However, although its caecum is morphologically distinct from the
other species, the relative length is small when compared to the more faunivorous
Metachirus nudicaudatus. Stomach length of Philander frenata is related to
a more carnivorous diet, while large intestine length of Didelphis aurita is related
to its omnivore diet. The digestive tract measurements of the other species
appear to be related with a variable degree of morphological differentiation
from a generalized form related to omnivory toward a more carnivorous diet.
Great caecum relative size distinguished Metachirus nudicaudatus from the
most other species and its relationship with diet is not well understood.
Is coat-colour polymorphism in Eurasian red squirrels (Sciurus vulgaris L.) adaptive?
Authors: Wauters Luc A. , Zaninetti Massimiliano , Tosi Guido , Bertolino Sandro
Published: July 2007

Coat-colour polymorphism, the relative frequencies of red, brown and black
fur-morphs, was examined in nine populations of the Eurasian red squirrel
(Sciurus vulgaris L.) in northern Italy. The proportions of the three different
coat-colours differed between populations. Red morphs were most common
in mixed woodlands of the Upper Po-plain, but rare in populations from the
Alps. The highest frequencies of black morphs were found in subalpine
conifer forests in the western Alps (Gran Paradiso) and in montane mixed
conifer forests in the central Alps (Valtellina). Coat-colour did not affect juvenile
survival, and there were no significant differences in mean foot length or
body mass among subadults and adults of different colour-morphs. However,
inter-population variation in the frequency of black morphs was positively
correlated with the proportion of spruce (and/or fir) in the forest and with the
density of trees. We suggest that the combination of a denser and more cryptic
fur in black morphs gives them a selective advantage over other coat colour
morphs in wet, dense spruce-fir forests of the Italian Alps, which could
explain the within- and between population variation in the relative frequencies
of coat colour phenotypes observed in this study.
Influence of Membrane and Filter Paper on Plane-Strain Testing of Soft Sedimentary Rock
Authors: Ye Guanlin , Zhang Feng , Yashima Atsushi , Aung Hla , Naito Kiyokaza
Published: July 2007

It is recognized that the intermediate principal stress plays an important role in the strength and the stress-dilatancy relation of soft sedimentary rock. However, few plane-strain/true triaxial experiments on soft rock have been referenced in literature due to the relatively high strength of geomaterials. With a conventional plane-strain apparatus, equipped with a prefixed plane-strain confining frame, it is difficult to obtain real isotropic consolidation before shearing. On the other hand, it has been found that the influence of the membrane/covering material on a high-strength specimen cannot be ignored. In this study, therefore, an innovative plane-strain test system for soft rock, that can overcome the shortcomings of the conventional type of apparatus, and issues related to specimen preparation are introduced. The results of drained compression tests and drained creep tests, along with theoretical simulations, are reported. The influence of the membrane and the filter paper are illustrated by a simple finite element method. A combination of experimental and theoretical approaches is employed to facilitate the understanding of the mechanical behavior of soft rock.
A Column Apparatus for Investigation of 1-D Unsaturated-Saturated Response of Sand-Geotextile Systems
Authors: Bathurst Richard J. , Ho Alvin F. , Siemens Greg
Published: July 2007

This paper is focused on the details of an experimental device that was used to investigate the transient unsaturated-saturated hydraulic response of sand-geotextile layers under conditions of 1-D constant head surface infiltration. The column was instrumented with inexpensive tensiometer-transducer devices to measure pore water pressures and conductivity probes to measure wetting front migration. The results of two tests are presented to demonstrate the use of the apparatus. One test was carried out using a sand column and the second test was nominally identical but included a horizontal woven geotextile layer at about mid-depth. The test results demonstrate that the apparatus can detect differences in the unsaturated response of the two systems. For example, transient ponding of water was measured above the surface of the geotextile layer commencing from an initial unsaturated condition despite the relatively high saturated permeability of the woven material. In addition, there was a small but detectable delay in the hydraulic flow after the wetting front reached the geotextile layer.
Ecology and Control of Russian Thistle (Salsola iberica) After Spring Wheat Harvest
Authors: Schillinger William F.
Published: July 2007

Russian thistle is the most problematic broadleaf weed for spring-sown crops in the low-precipitation (< 340 mm yr−1) region of the inland Pacific Northwest of the United States. A 6-yr field experiment was conducted at Lind, WA, to evaluate three postharvest control strategies for Russian thistle in continuous annual spring wheat. Postharvest treatments were (1) tillage with low-disturbance overlapping undercutter V-blade sweeps; (2) paraquat + diuron at the labeled rate, which is widely used by farmers; and (3) an untreated check (letting Russian thistle grow unhindered). The undercutter V-sweep consistently killed all Russian thistle with essentially no residue burial, and no seed was produced. In contrast, the paraquat + diuron treatment halted Russian thistle dry biomass production, but plants continued to extract soil water and produce an average of 310 seeds m−2on the lower branches. In the check, Russian thistle produced an average of 700 kg ha−1postharvest dry biomass and 5,670 seeds m−2. The undercutter V-sweep treatment had significantly more water in the 180-cm soil profile at time of wheat harvest, after a killing frost in October, and in mid March as well as greater spring wheat grain yield compared with the herbicide and check treatments. Results show that postharvest tillage with an undercutter V-sweep consistently achieved 100% control, retained ample wheat residue on the surface to control erosion, and was by far the most effective treatment in this experiment.
Rising Atmospheric Carbon Dioxide and Potential Impacts on the Growth and Toxicity of Poison Ivy (Toxicodendron radicans)
Authors: Ziska L. H. , Sicher R. C. , George K. , Mohan J. E.
Published: July 2007

Because of its ability to induce contact dermatitis, the establishment and spread of poison ivy is recognized as a significant public health concern. In the current study, we quantified potential changes in the biomass and urushiol content of poison ivy as a function of incremental changes in global atmospheric carbon dioxide concentration (CO2). We also examined the rate of new leaf development following leaf removal to simulate responses to herbivory as functions of both CO2 and plant size. The experimental CO2 values (300, 400, 500. and 600 µmol mol−1) corresponded approximately to the concentration that existed during the middle of the 20th century, the current concentration and near and long-term projections for this century (2050 and 2090), respectively. Over 250 d, increasing CO2 resulted in significant increases in leaf area, leaf and stem weight, and rhizome length relative to the 300 µmol mol−1 baseline with the greatest relative increase occurring from 300 to 400 µmol mol−1. There was a nonsignificant (P = 0.18) increase in urushiol concentration in response to CO2; however, because of the stimulatory effect of CO2 on leaf biomass, the amount of urushiol produced per plant increased significantly for all CO2 above the 300 µmol mol−1 baseline. Significant increases in the rate of leaf development following leaf removal were also observed with increasing CO2. Overall, these data confirm earlier, field-based reports on the CO2 sensitivity of poison ivy but emphasize its ability to respond to even small (∼ 100 µmol mol−1) changes in CO2 above the mid-20th century carbon dioxide baseline and suggest that its rate of spread, its ability to recover from herbivory, and its production of urushiol, may be enhanced in a future, higher CO2 environment.
Changes in the Regional Cerebral Perfusion After Eye Movement Desensitization and Reprocessing: A SPECT Study of Two Cases
Authors: Oh Dong-Hoon , Choi Joonho
Published: July 2007

Eye movement desensitization and reprocessing (EMDR) has emerged as a promising new treatment for trauma and other anxiety-based disorders. However, the neurobiological mechanism of EMDR has not been well understood. This study reports changes in the resting regional cerebral blood flow after successful EMDR treatment in two patients with posttraumatic stress disorder (PTSD). Brain 99mTc-ECD-SPECT (Technetium 99m–ethyl cysteinate dimmer–single photon emission computerized tomography) was performed before and after EMDR, and, in addition, a pre- and posttreatment comparison was made with 10 non-PTSD participants as a control group. After EMDR, cerebral perfusion increased in bilateral dorsolateral prefrontal cortex and decreased in the temporal association cortex. The differences between participants and normal controls also decreased. Changes appeared mainly in the limbic area and the prefrontal cortex. These results are in line with current understanding of neurobiology of PTSD. EMDR treatment appears to reverse the functional imbalance between the limbic area and the prefrontal cortex.
EMDR and Phantom Limb Pain: Theoretical Implications, Case Study, and Treatment Guidelines
Authors: Schneider Jens , Hofmann Arne , Rost Christine , Shapiro Francine
Published: July 2007

This article reviews the literature on EMDR treatment of somatic complaints and describes the application of Shapiro’s Adaptive Information Processing (AIP) model in the treatment of phantom limb pain. The case study explores the use of EMDR with a 38-year-old man experiencing severe phantom limb pain 3 years after the loss of his leg and part of his pelvis in an accident. Despite treatment at several rehabilitation and pain centers during the 3 years, and the use of opiate medication, he continued to experience persistent pain. After 9 EMDR treatment sessions, the patient’s phantom limb pain was completely ablated, and he was taken off medication. Effects were maintained at 18-month follow-up. The clinical implications of this application of EMDR are explored.

Inorganic Semiconductors for Flexible Electronics
Authors: Sun Y. , Rogers J. A.
Published: July 2007

This article reviews several classes of inorganic semiconductor materials that can be used to form high‐performance thin‐film transistors (TFTs) for large area, flexible electronics. Examples ranging from thin films of various forms of silicon to nanoparticles and nanowires of compound semiconductors are presented, with an emphasis on methods of depositing and integrating thin films of these materials into devices. Performance characteristics, including both electrical and mechanical behavior, for isolated transistors as well as circuits with various levels of complexity are reviewed. Collectively, the results suggest that flexible or printable inorganic materials may be attractive for a range of applications not only in flexible but also in large‐area electronics, from existing devices such as flat‐panel displays to more challenging (in terms of both cost and performance requirements) systems such as large area radiofrequency communication devices, structural health monitors, and conformal X‐ray imagers.
Graft polymerization synthesis and application of magnetic Fe3O4/polyacrylic acid composite nanoparticles
Authors: Hong R. Y. , Pan T. T. , Han Y. P. , Zhang S. Z. , Li H. Z. , Ding J.
Published: July 2007

Fe3O4 magnetic nanoparticles were prepared by coprecipitation using NH3 · H2O as the precipitating agent, and were characterized by Fourier transform infrared spectroscopy (FTIR), transmission electron microscopy (TEM), and X‐ray powder diffraction (XRD). The compatibility between the Fe3O4 nanoparticles and water were enhanced by grafting acrylic acid onto the nanoparticle surface. FTIR, XRD, thermogravimetry (TG), and differential scanning calorimetry (DSC) were used to characterize the resultant sample. The effects of initiator dosage, monomer concentration, and reaction temperature on the characteristics of surface‐modified Fe3O4 nanoparticles were investigated. Moreover, magnetic fluids (MF), prepared by dispersing the PAA grafted Fe3O4 nanoparticles in water, were characterized using UV–vis spectrophotometer, Gouy magnetic balance, and laser particle‐size analyzer. The rheological characteristics of magnetic fluid were investigated using capillary and rotating rheometers. The MF was added to prepare PVA thin film to improve mechanical properties. © 2007 Wiley Periodicals, Inc. J Appl Polym Sci 2007
Rheological and curing behavior of aqueous ambient self‐crosslinkable polyacrylate emulsion
Authors: Liu Xiaohua , Zhang Chuanzhi , Xiong Ting , Chen Deben , Zhong Anyong
Published: July 2007

An aqueous ambient crosslinkable polymer acrylic (AACPA) emulsion was obtained by adding adipic acid dihydrazide (ADH) to the polyacrylate emulsion incorporating diacetone acrylamide (DAAM), and this emulsion was synthesized by two feeding materials methods. The AACPA emulsion and its paint film were characterized with rheological measurements, laser light scattering, Fourier transform infrared, torsional braid analysis (TBA), DTA, and so on. The results showed that AACPA emulsion was pseudoplastic fluid and pseudoplasticity increased with increasing of DAAM content. The results also showed that water resistance, solvent resistance, and thermotacky temperature of AACPA paint film increased with increasing of the content of DAAM. The results dealing with curing behavior of the paint film showed that adding organic swelling solvent and organic acid to the AACPA emulsion can accelerate the curing speed of the paint film. © 2007 Wiley Periodicals, Inc.

Toughening of an epoxy resin with hydroxy‐terminated poly(arylene ether nitrile) with pendent tertiary butyl groups
Authors: Saxena Akanksha , Francis Bejoy , Rao V. Lakshmana , Ninan K. N.
Published: July 2007

Hydroxy‐terminated poly(arylene ether nitrile) oligomers with pendent tert‐butyl groups (PENTOH) were synthesized by the nucleophilic aromatic substitution reaction of 2,6‐dichlorobenzonitrile with tert‐butyl hydroquinone in N‐methyl‐2‐pyrrolidone medium with anhydrous potassium carbonate as a catalyst at 200°C in a nitrogen atmosphere. The PENTOH oligomers were blended with diglycidyl ether of bisphenol A epoxy resin and cured with 4,4′‐diaminodiphenyl sulfone. The curing reaction was monitored with infrared spectroscopy and differential scanning calorimetry. The morphology, fracture toughness, and thermomechanical properties of the blends were investigated. The scanning electron micrographs revealed a two‐phase morphology with a particulate structure of the PENTOH phase dispersed in the epoxy matrix, except for the epoxy resin modified with PENTOH with a number‐average molecular weight of approximately 4000. The storage modulus of the blends was higher than that of the neat epoxy resin. The crosslink density calculated from the storage modulus in the rubbery plateau region decreased with an increase in PENTOH in the blends. The fracture toughness increased more than twofold with the addition of PENTOH oligomers. The tensile strength of the blends increased marginally, whereas the flexural strength decreased marginally. The dispersed PENTOH initiated several toughening mechanisms, which improved the fracture toughness of the blends. The thermal stability of the epoxy resin was not affected by the addition of PENTOH to the epoxy resin. © 2007 Wiley Periodicals, Inc. J Appl Polym Sci 2007
Synthesis of 2‐phenyl‐3‐hydroxyethanyl‐1,3‐oxazolidine and its application as latent curing agents
Authors: Gao Jun , Zhang Ping , Lei Jingxin
Published: July 2007

A kind of new compound of 2‐phenyl‐3‐hydroxyethanyl‐1,3‐oxazolidine was successfully synthesized by addition–condensation reaction of phenyl aldehyde and β‐hydroxylethanolamine and purified by vacuum distillation. Its purity was examined by gas chromatographic analysis. Its structure was confirmed by 13C NMR and FTIR. When this compound was added as a latent curing agent in single‐component moisture‐curable polyurethane system (SPU), bubbles of SPU formed during curing was obviously restrained, and the elongation at break of the cured SPU contained a certain content of 2‐phenyl‐3‐hydroxyethanyl‐1,3‐oxazolidine was increased to 16 times when compared with that uncontained this oxazolidine derivative. © 2007 Wiley Periodicals, Inc.

Ring‐opening polymerization of trimethylenecarbonate and its copolymerization with ϵ‐caprolactone by lanthanide (II) aryloxide complexes
Authors: Zhao B. , Lu C. R. , Shen Q.
Published: July 2007

Lanthanide metal (II) 2,6‐di‐tert‐butylphenoxide complexes (ArO)2Ln(THF)3(Ln = Sm1, Yb2) alone have been developed to catalyze the ring‐opening polymerization of trimethylenecarbonate (TMC) and random copolymerization of TMC and ε‐caprolactone (ε‐CL) for the first time. The influence of reaction conditions, such as initiator, initiator concentration, polymerization temperature, and polymerization time, on monomer conversion, molecular weight, and molecular weight distribution of the resulting PTMC was investigated. It was found that the divalent complex1showed higher activity for the polymerization of TMC than complex2. The random structure and thermal behavior of the copolymers P(TMC‐co‐CL) have been characterized by1H NMR,13C NMR, GPC, and DSC analysis. © 2007 Wiley Periodicals, Inc. J Appl Polym Sci 2007
Pervaporation separation of water/ethanol mixture using asymmetric ion‐exchange membranes containing aluminum ions
Authors: Chen Shih‐Hsiung , Liou Rey‐May , Shih Chi‐Yu , Lai Cheng‐Lee , Lai Juin‐Yih
Published: July 2007

The asymmetric aluminum ion exchange polysulfone membranes have successfully been prepared for the dehydration of ethanol‐water mixture. The relationship between the membrane morphology, separation performance, and the ion content of membranes were discussed in this study. The experimental results showed that the separation performance of those membranes was increased upon increasing the degree of aluminum ion exchange in polysulfone membranes. Both permeation rate and separation factors of those membranes increased with increasing the degree of ion exchange. The increase in separation performance of aluminum ion exchange membranes was mainly attributed to ion crosslinking in polymer network and the hydration effects of exchanged ion in membranes. On the other hand, the operating temperature in the PV process showed a significant influence on the dehydration of water molecules in the permeate. An increase in temperature increased the permeation flux of permeate but slightly decreased its selectivity. The aluminum asymmetric ions in membranes showed a strong influence on permselectivity of asymmetric ion exchange membranes. © 2007 Wiley Periodicals, Inc. J Appl Polym Sci 2007
