Redox‐Controlled Photosensitization of Nanocrystalline Titanium Dioxide
Authors: Szaciłowski Konrad , Macyk Wojciech , Hebda Maciej , Stochel Grażyna 
Published: October 2006

AbstractPhotosensitization of nanocrystalline titanium dioxide materials has been achieved by chemisorption of the pentacyanothiamineferrate(II) complex, which offers a relatively high redox potential that determines the photoelectrochemical properties of the photosensitized TiO2. The adsorbed pentacyanoferrate complex binds to TiO2 through the cyanide bridge and forms a new surface complex characterized by a metal‐to‐metal charge‐transfer transition (MMCT) (FeII→TiIV). The photosensitization can be observed only at low potentials at which FeII moieties are present. Photocurrent switching between anodic and cathodic can be induced by varying either the photoelectrode potential or the wavelength of the incident light. Simple molecular modeling—together with spectroscopic and electrochemical measurements—allows the elucidation of the mechanism of the observed photoelectrochemical behavior.
In‐group reassurance in a pain setting produces lower levels of physiological arousal: direct support for a self‐categorization analysis of social influence

Published: October 2006

AbstractA large body of research demonstrates a strong social component to people's pain experiences and pain‐related behaviours. We investigate this by examining the impact of social‐influence processes on laboratory‐induced pain responses by manipulating the social‐categorical relationship between the person experiencing pain and another who offers reassurance. We show that physiological arousal associated with laboratory‐induced pain is significantly lower in normal, healthy participants following reassurance about the pain‐inducing activity when that reassurance comes from an in‐group member in contrast to reassurance from an out‐group member and a no reassurance control. These data are consistent with predictions derived from self‐categorization theory, providing convincing empirical support of its analysis of social influence using a non‐reactive measure. These data also represent a clear advance within the pain literature by identifying a possible common process to the social‐psychological component of pain responses.

The potential of electrophoretic mobility shift assays for clinical mutation detection
Authors: Hestekin Christa N. , Barron Annelise E. 
Published: October 2006

AbstractAs the understanding of the links between genetic mutations and diseases continues to grow, there is an increasing need for techniques that can rapidly, inexpensively, and sensitively detect DNA sequence alterations. Typically, such analyses are performed on PCR‐amplified gene regions. Automated DNA sequencing by capillary array electrophoresis can be used, but is expensive to apply to large numbers of patient samples and/or large genes, and may not always reveal low‐abundance mutations in heterozygous samples. Many different types of genetic differences need to be detected, including single‐base substitutions and larger sequence alterations such as insertions, deletions, and inversions. Electrophoretic mobility shift assays seem well suited to this purpose and could be used for the efficient screening of patient samples for sequence alterations, effectively reducing the number of samples that must be subjected to full and careful sequencing. While there is much promise, many of the mobility shift assays presently under development have yet to be demonstrated to have the high sensitivity and specificity of mutation detection required for routine clinical application. Hence, further studies and optimization are required, in particular the application of these methods not only to particular genes but also to large numbers of patient samples in blinded studies aimed at the rigorous determination of sensitivity and specificity. This review examines the state‐of‐the‐art of the most commonly used mobility shift assays for mutation detection, including denaturing gradient gel electrophoresis, TGGE, SSCP, heteroduplex analysis, and denaturing HPLC.
Closed‐form generalised power correlation coefficient of Ricean channels
Authors: Mendes José Ricardo , Yacoub Michel Daoud , da Costa Daniel Benevides 
Published: October 2006

AbstractExact, closed‐form and general expressions of the marginal and joint moments as well as of the correlation coefficient of the instantaneous powers of two Ricean signals are derived. All statistics are expressed as finite sums of simple functions of the model parameters. The model includes environments where the Ricean factor and the mean power of one signal are different from their counterparts of the other signal. Some plots illustrate the generalised power correlation coefficient provided in this work. Coherence parameters are derived and practical values for system design are suggested.

Verbal memory performance during subchronic challenge with a selective serotonergic and a mixed action antidepressant
Authors: Wingen M. , Langer S. , Ramaekers J. G. 
Published: October 2006

AbstractObjectivesEffects of escitalopram 10–20 mg/day and mirtazapine 30–45 mg/day on verbal memory of 18 healthy participants were assessed in a randomized, double‐blind, placebo‐controlled, three‐way crossover trial.MethodEach treatment period lasted for 15 days and was separated from the next period by a washout period of at least 13 days. Participants received an evening dose of escitalopram 10 mg, mirtazapine 30 mg, or placebo from days 1 to 7 and an evening dose of escitalopram 20 mg, mirtazapine 45 mg, or placebo from days 8 to 15. On days 2, 9, and 16 a visual verbal memory task was performed measuring drug effects during the acute phase, after dose increase and at steady state.ResultsEscitalopram did not affect immediate or delayed verbal memory score throughout treatment. During mirtazapine treatment, participants performed less well in the overall immediate recall score compared to placebo. This impairment was most pronounced in the final trial of the visual verbal learning task.ConclusionVerbal memory was not affected by acute and subchronic escitalopram treatment in healthy participants. Overall immediate verbal memory was slightly but significantly impaired throughout mirtazapine treatment, probably due to a general reduction in overall arousal caused by H1 blockade.

AbstractReplacement of antipsychotic drugs with quetiapine (QTP) was tried in a naturalistic setting in chronic schizophrenic patients who still showed moderate psychiatric symptoms and either showed extrapyramidal symptoms (EPS) or took anti‐parkinson drugs for the EPS. QTP was added on and gradually increased while the previous drugs were tapered and discontinued whenever possible. Clinical symptoms, objective and subjective QOL, and EPS were measured before and 6 months after QTP addition, using Brief Psychiatric Rating Scale (BPRS), Quality of Life Scale (QLS), Schizophrenia Quality of Life Scale (SQLS) and Drug‐Induced Extrapyramidal Symptom Scale (DIEPSS), respectively. Twenty‐one patients completed the trial and received the assessment. It was found that replacement with QTP‐improved clinical symptoms, objective and subjective QOL and EPS. This improvement was equally observed in not only patients who switched to QTP monotherapy (n = 11) but also patients who took QTP together with reduced small doses (4.4 ± 4.3 mg/day) of previous drugs (n = 11). The results suggest that replacement with QTP improves symptoms as well as objective and subjective QOL in a subgroup of schizophrenia. Copyright © 2006 John Wiley & Sons, Ltd.
Maternal sensitivity and behaviour problems in young children with developmental delay
Authors: Niccols Alison , Feldman Maurice 
Published: October 2006

AbstractChildren with developmental delay are at increased risk for behaviour problems, but little is known about risk and resilience factors. Previous research has established links between maternal sensitivity and behaviour problems in typically developing children, but no studies have examined maternal sensitivity in the development of behaviour problems in children with developmental delay. In this study, we coded videotaped interactions of 30 2‐year‐olds with developmental delay and their mothers using the maternal behaviour Q‐sort and a child behaviour coding system. Mothers completed the child behaviour checklist when their children were 2 and 3 years old. Results revealed significant inverse relations between maternal sensitivity and concurrent and later externalizing problems, and significant positive relations between maternal sensitivity and concurrent observed appropriate behaviour (compliance and social engagement). This study informs developmental theory and identifies an important maternal variable that may reduce the risk of behaviour problems in children with developmental delay.

Static strain stimulates expression of matrix metalloproteinase‐2 and VEGF in microvascular endothelium via JNK‐ and ERK‐dependent pathways
Authors: Milkiewicz Malgorzata , Mohammadzadeh Forough , Ispanovic Eric , Gee Eric , Haas Tara L. 
Published: October 2006

AbstractVEGF and MMP protein production are both required for exercise‐induced capillary growth in skeletal muscle. The underlying process by which muscle activity initiates an angiogenic response is not established, but it is known that mechanical forces such as muscle stretch are involved. We hypothesized that stretch of skeletal muscle microvascular endothelial cells induces production of MMP‐2 and VEGF through a common signal pathway. Endothelial cells were grown on Bioflex plates and exposed to 10% static stretch for up to 24 h. MMP‐2 protein level was measured by gelatin zymography and VEGF, MMP‐2, and MT1‐MMP mRNA levels were quantified by real‐time quantitative PCR. ERK1/2 and JNK phosphorylation and VEGF protein levels were assessed by Western blotting. Effects of mitogen‐activated protein kinases (MAPKs) (ERK1/2, JNK) and reactive oxygen species (ROS) on stretch‐induced expression of MMP‐2 and VEGF were tested using pharmacological inhibitors. Stretching of endothelial cells for 24 h caused significant increases in MMP‐2 protein and mRNA level, but no change in MT1‐MMP mRNA. While MMP‐2 protein production was enhanced by H2O2 in unstretched cells, ROS inhibition during stretch did not diminish MMP‐2 mRNA or protein production. Inhibition of JNK suppressed stretch‐induced MMP‐2 protein and mRNA, but inhibition of ERK had no effect. In contrast, inhibition of ERK but not JNK attenuated the stretch‐induced increase in VEGF mRNA. Our results demonstrate that differential regulation of MMP‐2 and VEGF by MAPK signal pathways contribute to stretch‐induced activation of microvascular endothelial cells. J. Cell.

AbstractPurposeTo preoperatively visualize the course of the facial nerve, which is displaced by vestibular schwannoma, using diffusion tensor (DT) tractography, and to evaluate the agreement with surgical findings.Materials and MethodsThe subjects were eight patients with vestibular schwannoma who had undergone removal surgery. DT MR images were obtained and tracts that were considered to represent the facial nerve were constructed. We assessed the success rate for tract construction and evaluated the agreement between tractography findings and surgery.ResultsWe obtained a tract that connected the internal auditory meatus and brainstem, and was considered to represent the facial nerve in seven of eight cases. The course of the constructed tract agreed with surgical findings in five of these seven cases. One exception was a case in which the tumor was too large to enable intraoperative observation of the facial nerve; however, the facial nerve appeared to be displaced anteriorly at intracapsular resection, in agreement with tractography. In the other case, the schwannoma was mostly cystic.ConclusionTractographs constructed using MR tensor images enabled us to identify tracts considered to represent facial nerves. We consider DT tractography to be a useful tool for preoperatively predicting facial nerve displacement in vestibular schwannoma. J. Magn. Reson. Imaging 2006. © 2006 Wiley‐Liss, Inc.
Fast magnetization‐driven preparation for imaging of contrast‐enhanced coronary arteries during intra‐arterial injection of contrast agent
Authors: Gui Dawei , Tsekos Nikolaos V. 
Published: October 2006

AbstractPurposeTo implement a short‐duration magnetization preparation sequence, which consists of a saturation followed by multiple inversion pulses, for imaging of short‐T1 species and suppression of long‐T1 species.Materials and MethodsComputer optimizations were performed to derive preparation schemes that 1) suppress long‐T1 background species with T1 ≥ 250 msec, 2) maximize the MZ of contrast‐enhanced (CE) structures with T1 ≤ 50 msec, and 3) have a preparation duration in the range of 200 msec. The optimized sequences were tested on a phantom and a pig model instrumented with an intracoronary catheter for infusion of contrast media.ResultsComputer simulations generated preparation schemes with durations of 165–225 msec depending on the number of preparation pulses used, which generated saturation of over 98% for T1 > 250 msec, and about a 30% reduction for 20 msec < T1 < 50 msec. The phantom studies validated the performance of the optimized sequences. Coronary artery angiograms (380 msec for preparation and image acquisition) demonstrated signal‐to‐noise ratios (SNRs) in the range of 13–15.5 and contrast‐to‐noise ratios (CNRs) in the range of 6.3–7.1 in the CE coronary vessels.ConclusionThis work demonstrates that fast magnetization‐driven preparation schemes can be implemented for fast imaging of CE coronary vessels with efficient saturation of background species.

AbstractPurposeTo study cerebral responses evoked from mechanoreceptors in the human foot sole using a computer‐controlled vibrotactile stimulation system.Materials and MethodsThe stimulation system consisted of two stationary moving magnet actuators with indentors to gently contact and vibrate the foot sole during functional MRI (fMRI) experiments. To allow independent settings of contact force (0–20 N) and intensity of vibration (frequency range = 20–100 Hz) the actuators were controlled by a digital servo loop. For fMRI experiments with complex stimulus protocols, both vibrating probes were further operated under supervisory control.ResultsThe MR compatibility of this electromagnetic system was tested in a 1.5T scanner with an actively shielded magnet (Siemens Magnetom Sonata). Blood oxygenation level‐dependent (BOLD) responses were detected in the contralateral left pre‐ and postcentral gyrus, bilaterally within the secondary somatosensory cortex, bilaterally within the supplementary motor cortex, and bilaterally within the anterior cingular gyrus.ConclusionThis stimulation device provides a new tool for identifying cerebral structures that convey sensory information from the foot region, which is of promising diagnostic value, particularly for assessing sensorimotor deficits resulting from brain lesions.
