Authors: Stone Kimberly E. , Eastman Emmanuella M. , Gielen Andrea C. , Squires Barbara , Hicks Glenda , Kaplin Dana , Serwint Janet R. 
Published: July 2007

OBJECTIVES. Residential injuries cause significant morbidity and mortality in infants and young children. The American Academy of Pediatrics recommends initiating injury-prevention counseling during health supervision visits in the first 6 months of life. The objectives of this study were to describe and compare self-reported and observed home safety practices in urban, low-income families who were expecting or had a child &lt;12 months old and to assess the feasibility of using safety products depending on the design and repair of urban homes.PARTICIPANTS AND METHODS. Women who were pregnant or had an infant &lt;12 months old and who were enrolled in East Baltimore's Healthy Start home-visiting program were eligible for the study. For this pilot project, we used a prospective predesign/postdesign. Maternal self-report and investigator home observations documented the use of working smoke alarms on each level of the home, stair gates or doors blocking the top and bottom of all staircases, adult medication storage in locked cabinets, and the environmental feasibility of safety-product use.RESULTS. Home safety practices were higher by maternal self-report than by investigator observation. Fifty-five percent of families who reported a working smoke alarm on every level of the home had nonworking or absent smoke alarms noted during investigator observation. Of assessed staircases, 67% could not accommodate a wall-mounted gate at the top of the stairs, and 38% could not accommodate a pressure-mounted gate at the bottom of the stairs. Although most families reported locked storage of medications, 77% had unlocked medication storage documented during home observation.CONCLUSIONS. In this sample of urban families, implementation of American Academy of Pediatrics-recommended safety practices is low. The structural design of urban homes may be a significant barrier to home safety-product use. The American Academy of Pediatrics Injury Prevention Program sheets, manufacturers of safety products, and legislators need to address injury-prevention issues unique to urban, low-income families.

OBJECTIVE. The objective of this study was to examine differences in intellectual capacities between children with and without soiling, daytime wetting, and bed-wetting.METHODS. This study was based on a population of &gt;6000 children (age range: 7 years 6 months to 9 years 3 months; median: 7 years 6 months) from the United Kingdom–based Avon Longitudinal Study of Parents and Children. Data on wetting and soiling were obtained from a questionnaire completed by parents. The Wechsler Intelligence Scale for Children–Third Edition was administered at a research clinic.RESULTS. Bed-wetting was associated with lower Wechsler Intelligence Scale for Children–Third Edition IQ scores compared with control subjects, particularly performance IQ. This difference remained after exclusion of children with an IQ of &lt;70 and adjustment for gender, stressful life events, and sociodemographic background. There were fewer differences in IQ scores between children with and without soiling or daytime wetting. Co-occurring wetting and soiling were associated with lower IQ scores than isolated soiling, daytime wetting, or bed-wetting, but this was mostly attributable to an overrepresentation of children with an IQ of &lt;70 in the co-occurrence group.CONCLUSIONS. It is hypothesized that the differences in intellectual capacities between children with and without bed-wetting are associated with maturational deficits of the central nervous system. There was less evidence for differences in intellectual capacities between children with and without soiling and daytime wetting. The central nervous system is involved to a lesser extent in soiling and daytime wetting, because peripheral influences from the bladder and gut play a greater role.

Published: July 2007

Background and Purpose: The primary purpose of this study was to develop a clinical prediction rule (CPR) for identifying patients with knee pain and clinical evidence of knee osteoarthritis (OA) with favorable short-term response to hip mobilizations. The secondary purpose was to determine the predictive validity of individual clinical tests for identifying these same patients.Subjects and Methods: Sixty subjects with knee OA, aged 51 to 79 years, completed self-report questionnaires, a clinical examination of the hip and knee, and functional tests and were treated with 4 hip mobilizations. Follow-up testing was completed 2 days later. The reference criterion for determining a favorable response was either (1) a decrease of at least 30% on composite Numerical Pain Rating Scale score obtained during functional tests or (2) a Global Rating of Change Scale score of at least 3.Results: The CPR developed in this study comprised 5 variables: (1) hip or groin pain or paresthesia, (2) anterior thigh pain, (3) passive knee flexion less than 122 degrees, (4) passive hip medial (internal) rotation less than 17 degrees, and (5) pain with hip distraction. Based on the pretest probability of success (68%), the presence of one variable had a positive likelihood ratio of 5.1 and increased the probability of a successful response to 92% at 48-hour follow-up. If 2 variables were present, the positive likelihood ratio was 12.9 and the probability of success increased to 97%.Discussion and Conclusion: The results suggest that the CPR developed in this study could improve clinicians’ decision making and efficiency in examining and treating patients with knee OA.
Use of Demographic and Quantitative Admissions Data to Predict Academic Difficulty Among Professional Physical Therapist Students
Authors: Utzman Ralph R , Riddle Daniel L , Jewell Dianne V 
Published: July 2007

Background and Purpose: The purpose of this study was to determine whether admissions data could be used to estimate physical therapist students' risk for academic difficulty.
Subjects: A nationally representative sample of 20 physical therapist education programs provided data on 3,582 students.
Methods: Programs provided data regarding student demographic characteristics, undergraduate grade point average (uGPA), quantitative and verbal Graduate Record Examination scores (qGRE, vGRE), and academic difficulty. Data were analyzed using logistic regression. Rules for predicting risk of academic difficulty were developed.
Results: A prediction rule that included uGPA, vGRE, qGRE, age, and race or ethnicity was developed from the entire sample. Prediction rules for individual programs showed large variation.
Discussion and Conclusion: Undergraduate grade point average, GRE scores, age, and race or ethnicity can be useful for estimating student academic risk. Programs should calculate their own estimates of student risk. Academic programs should use risk estimates in combination with other data to recruit, admit, and retain students.

Published: July 2007

Background and Purpose: Random practice of motor tasks has been shown to enhance motor learning. The purpose of this study was to investigate the effects of task practice order (random, blocked) on motor learning in adults with Parkinson disease (PD).Subjects: Twenty adults with mild PD and 20 age-matched adults (controls) participated in the study.Methods: Participants in both groups (PD and control) practiced 3 movement tasks with either a blocked or a random practice order. This 2 participant group × 2 practice order design resulted in 4 experimental groups. The Trail Making Test was administered to all participants to determine task-switching capability. Motor performance on the arm movement tasks was quantified on the basis of the root-mean-square error difference between the goal movement task and each participant's response.Results: The task-switching capability of the control group was superior to that of the PD group. For acquisition, in general, participants in the control group performed with significantly less error than participants in the PD group. For retention, participants in the control group who practiced with a random order performed more accurately than participants in the control group who practiced with a blocked order. However, for the PD group, the findings were reversed; participants who practiced with a blocked order performed more accurately than participants who practiced with a random order. These findings resulted in a group × practice order interaction.Discussion and Conclusion: These pilot study data suggest that, contrary to the findings for age-matched control learners, for learners with mild PD, a blocked practice order may be better than a random practice order for motor learning.
Sex Differences in Career Expectations of Physical Therapist Students
Authors: Johanson Marie A 
Published: July 2007

Background and Purpose: There are some sex differences in the career activities of physical therapists. The purpose of this study was to determine whether these sex differences are reflected in the career expectations of physical therapist students.Subjects: Participants were 919 physical therapist students.Methods: Faculty at 34 physical therapist education programs distributed questionnaires to 1,172 of their students. The 919 returned questionnaires generated a response rate of 78.4%. Sex differences in career expectations were statistically analyzed with logistic regression.Results: Men showed statistically significantly higher odds than women of expecting to own a private practice, to become a faculty member, to become a physical therapist manager or administrator, to publish articles in professional journals, and to have a higher income in the first year of employment.Discussion and Conclusion: At the outset of physical therapist education, there are sex differences in the career expectations of physical therapist students.
Strong Carbon‐Nanotube–Polymer Bonding by Microwave Irradiation
Authors: Wang C. Y. , Chen T. H. , Chang S. C. , Cheng S. Y. , Chin T. S. 
Published: July 2007

AbstractThe vigorous response of multiwalled carbon nanotubes (MWNTs) to microwave irradiation, leading to the release of a large amount of heat, is used to locally melt a plastic matrix adjacent to the nanotubes within a period of seconds. This results in the intercalation of the MWNTs into the polymer matrix at room temperature without any physical damage to the polymer. The so‐called “microwave welding” approach creates a new paradigm for the formation of very strong MWNT–polymer bonds without the use of any adhesive, and represents a significant step forward for the fabrication of functional nanotube composites. Here, we demonstrate the implications of the anisotropic alignment of MWNTs in polymers, patterned conductors/resistors for soft electronics, and high‐strength composites, where the MWNTs are ‘soldered' to flexible polymer substrates.

Published: July 2007

AbstractIn the present work, design, synthesis, and pharmacological evaluation of the analgesic, anti‐inflammatory, and ulcerogenic‐index activities of new 3‐subsituted‐amino‐2‐methylsulfanyl‐5,6,7,8‐tetrahydro‐3H‐benzo[4,5]thieno[2,3‐d]pyrimidin‐4‐ones, structurally planed by exploiting a clear concept of bio‐isosterism, are reported. All compounds exhibited significant analgesic and anti‐inflammatory activity. Compounds A1, A3 showed higher analgesic activity and more potent anti‐inflammatory activity than that of the reference compound diclofenac sodium. Interestingly, the test compounds showed only mild ulcerogenic potential when compared to that of acetylsalicylic acid.
The use of CdTe quantum dot fluorescent microspheres in fluoro‐immunoassays and a microfluidic chip system
Authors: Ma Qiang , Wang Xinyan , Li Yabing , Su Xingguang , Jin Qinhan 
Published: July 2007

AbstractPolystyrene fluorescent microspheres prepared by deposition of CdTe quantum dots (QDs) are used in an immunoassay in this study. CdTe QDs/polyelectrolyte multilayers on the surface of polystyrene microspheres have been formed by layer‐by‐layer self‐assembly via electrostatic interactions. As a model antigen, rabbit IgG has been bound to the outermost layer of the fluorescent microspheres. The immunoreaction between fluorescent microspheres/rabbit IgG and the corresponding antibody was confirmed by change of the fluorescence spectrum and competitive immunoassay. This approach allowed detection of the antigen (rabbit IgG) in the range 1–500 mg/L, based on the change in the fluorescence intensity of the reporter (fluorescent microspheres/rabbit IgG). A novel microfluidic chip device with a laser‐induced fluorescence system was established and used for the detection of fluorescent microspheres in this study.

Bioluminescence characteristics of a tropical terrestrial fungus (Basidiomycetes)
Authors: Deheyn Dimitri D. , Latz Michael I. 
Published: July 2007

AbstractFreshly collected samples of luminous mycelium of a terrestrial fungus from Panama were investigated for their bioluminescence characteristics. Taxonomic identification of fungal species could not be determined because of the lack of fruiting bodies. Fluorescence excited by 380 nm illumination had an emission spectrum with a main peak at 480 nm and additional chlorophyll peaks related to the wood substrate. Bioluminescence appeared as a continuous glow that did not show any diel variation. The light production was sensitive to temperature and decreased with temperatures higher or lower than ambient. Bioluminescence intensity was sensitive to hydration, increasing by a factor of 400 immediately after exposure to water and increasing by a factor of 1 million after several hours. This increase may have occurred through dilution of superoxide dismutase, which is a suppressive factor of bioluminescence in fungus tissue. The mycelium typically transports nutritive substances back to the fruiting body. The function of luminescent mycelium may be to increase the intensity of light from the fungus and more effectively attract nocturnal insects and other animals that serve as disseminating vectors for fungal spores.

Luminescence studies on RbI:Tb3+ crystals
Authors: Manimozhi P. K. , Muralidharan G. 
Published: July 2007

AbstractOptical absorption, photoluminescence, thermoluminescence (TL) and photostimulated luminescence (PSL) studies on RbI:Tb3+ crystals irradiated with γ‐rays is reported. Photoluminescence of these crystals exhibits characteristic Tb3+ emissions, due to transitions from the 5D3 and 5D4 levels to various levels of the 7F septet. On F‐bleaching the γ‐irradiated crystals, Z3 centres are observed. The TL glow curve indicates a two‐step thermal annihilation process for the radiatively created defects. The presence of the characteristic emissions due to terbium ions in the photostimulation at the F‐band, and TL emissions under both glow peaks, confirm the participation of Tb ions in the defect production and recombination processes. Trap parameters for the TL process are calculated and presented. The low temperature glow peak is attributable to Z3 centres. Copyright © 2007 John Wiley & Sons, Ltd.
Novel chemiluminescence system with calcein as chemiluminescent reagent
Authors: Nie Fei , Lu Jiuru 
Published: July 2007

AbstractChemiluminescence (CL) was observed when calcein reacted with potassium ferricyanide. Several metal ions and organic compounds could enhance this CL signal. The possible mechanisms for the CL reactions and the enhancement effect were investigated via studies of the CL kinetic characteristics, the CL spectra of some related reactions, the UV absorption spectra and the fluorescence spectra of some substances. The merits of figures for some substances with CL activity were obtained. A new CL system with calcein as the CL reagent was preliminarily established. Copyright © 2007 John Wiley & Sons, Ltd.

AbstractThe synthesis and self‐assembly behaviour of porphyrin dodecamers 1H2 and Zn–1, which consist of twelve porphyrins that are covalently attached to a central aromatic core, is described. According to STM, 1D and 2D NMR studies, and molecular modelling calculations, the porphyrin dodecamers have a yo‐yo‐shaped structure. Their large π surface, in combination with their disk‐like shape, allows them to form self‐assembled structures, which in the case of Zn–1 can be tuned by adding bidentate ligands. The self‐assembly of the molecules at the liquid–solid interface of 1‐phenyloctane with highly oriented pyrolytic graphite or Au(111) was imaged by using STM. The porphyrin disks in the self‐assembled arrays have an edge‐on orientation on the surface. The addition of bidentate axial ligands to the Zn–1 molecules in the arrays allows their intermolecular distance to be precisely controlled.
Iron‐Catalyzed Oxidation of Thioethers by Iodosylarenes: Stereoselectivity and Reaction Mechanism
Authors: Bryliakov Konstantin P. , Talsi Evgenii P. 
Published: July 2007

AbstractCatalytic properties of a series of iron(III)–salen (salen=N,N′‐bis(salicylidene)ethylenediamine dianion) and related complexes in asymmetric sulfoxidation reactions, with iodosylarenes as terminal oxidants, have been explored. These catalysts have been found to efficiently catalyze oxidation of alkyl aryl sulfides to sulfoxides with high chemoselectivity (up to 100 %) and moderate‐to‐high enantioselectivity (up to 84 % with isopropylthiobenzene and iodosylmesitylene), the TON (TON=turnover number) approaching 500. The influence of the ligand (electronic and steric effects of the substituents), oxidant, and substrate structures on the oxidation stereoselectivity has been investigated systematically. The structure of the reactive intermediates (complexes of the type [FeIII(ArIO)(salen)] and the reaction mechanism have been revealed by both mechanistic studies with different iodosylarenes and direct in situ 1H NMR observation of the formation of the reactive species and its reaction with the substrate.
