Epidemiology of occupational injuries and illnesses in a university population: A focus on age and gender differences
Authors: Saleh Shadi S. , Fuortes Laurence , Vaughn Thomas , Bauer Eric P. 
Published: August 2002

AbstractBackgroundOccupational injuries and illnesses are a major preventable public health problem.MethodsThis study evaluated the incidence, nature, and cause of awarded workers' compensation claims for a large state university and teaching hospital. Rates and types of injury were compared across age and gender.ResultsRates of injury varied over twofold with age, with those 16–25 having the lowest rates of injury and those 36–45 having the highest rates. Claims rates were 1.36‐fold higher for women than men. Women had higher rates for injury resulting from lifting, falling, noxious exposures, repetitive motion, and carpal tunnel syndrome. Similarly women had significantly higher rates of claims for pain, sprains, bruises, burns, concussion, and inhalation injury; with lower rates of cuts, ligament injury, and jammed joints.ConclusionsThese group differences suggest the need to examine age and gender job distributions and relevant ergonomic and environmental causative factors.

The social consequences of occupational injuries and illnesses
Authors: Dembe Allard E. 
Published: August 2002

AbstractBackgroundMost outcome studies of occupational injuries and illnesses have tended to focus on direct economic costs and duration of work disability. Rarely have the broader social consequences of work‐related disorders or their impacts on injured workers' families, coworkers, and community been investigated. This paper examines a wide range of social consequences including workers' psychological and behavioral responses, vocational function, and family and community relationshipsMethodsLiterature review and development of conceptual frameworkResultsComplex and multifactorial relationships are described whereby occupational injuries and illnesses produce a variety of social consequences involving filing and administration of workers' compensation insurance claims, medical care experiences, domestic function and activities of daily living, psychological and behavioral responses, stress, vocational function, rehabilitation and return to work, and equity and social justiceConclusionA research agenda is proposed for guiding future investigations in this field.

Published: August 2002

AbstractChimerism in humans appears to be a rare phenomenon that is usually discovered by accident. Here we describe a stillborn male fetus with multiple congenital anomalies which was found to have two cytogenetically abnormal cell lines, 47,XY, +21 and 47, XX, +12. The difference in sex chromosome constitution between the cell lines indicated that the fetus had dispermic chimerism. To our knowledge, this is the first report of chimerism with two abnormal cell lines. © 2001 Wiley‐Liss, Inc.

AbstractWe performed a two‐stage genome screen to search for novel risk factors for late‐onset Alzheimer disease (AD). The first stage involved genotyping 292 affected sibling pairs using 237 markers spaced at approximately 20 cM intervals throughout the genome. In the second stage, we genotyped 451 affected sibling pairs (ASPs) with an additional 91 markers, in the 16 regions where the multipoint LOD score was greater than 1 in stage I. Ten regions maintained LOD scores in excess of 1 in stage II, on chromosomes 1 (peak B), 5, 6, 9 (peaks A and B), 10, 12, 19, 21, and X. Our strongest evidence for linkage was on chromosome 10, where we obtained a peak multipoint LOD score (MLS) of 3.9. The linked region on chromosome 10 spans approximately 44 cM from D10S1426 (59 cM) to D10S2327 (103 cM). To narrow this region, we tested for linkage disequilibrium with several of the stage II microsatellite markers. Of the seven markers we tested in family‐based and case control samples, the only nominally positive association we found was with the 167 bp allele of marker D10S1217 (chi‐square = 7.11, P = 0.045, df = 1). © 2002 Wiley‐Liss, Inc.

Published: August 2002

AbstractThe combination of autosomal dominant, early onset Paget disease of bone (PDB) and muscular dystrophy is an unusual disorder. We recently mapped the disorder in a large family from central Illinois with PDB and proximal limb‐girdle type of muscular dystrophy (LGMD), and in 3 additional families with hereditary inclusion body myopathy (HIBM), Paget disease of bone and frontotemporal dementia, to a unique locus on chromosome 9p21.1‐q12. The present study describes an unrelated 10‐member family with autosomal dominant PDB and a scapuloperoneal type of muscular dystrophy. Clinical, biochemical, and radiological evaluations were performed to delineate clinical features in this family. Progression of the muscular dystrophy begins with weakness in the distal muscles of the legs accompanied by foot drop. EMG and muscle biopsy are compatible with a primary dystrophy. Onset of Paget disease is early, at a mean age of 41 years, with initial distribution in the long bones and eventual infiltration of the spine and pelvis. Creatine phosphokinase (CPK) and alkaline phosphatase levels are elevated in affected individuals. Molecular analyses excluded all known loci for Paget disease of bone, scapuloperoneal muscular dystrophy (SPMD), fascioscapulohumeral muscular dystrophy (FSH), amyotrophic lateral sclerosis (ALS), Bethlem myopathy, two forms of autosomal dominant limb‐girdle muscular dystrophy (LGMD), and the critical region for LGMD or HIBM/PDB on chromosome 9p21.1‐q12, thus providing evidence for genetic heterogeneity among families with the unique combination of muscular dystrophy and Paget disease of bone. © 2002 Wiley‐Liss, Inc.
Sequencing of the GRIK1 gene in patients with juvenile absence epilepsy does not reveal mutations affecting receptor structure
Authors: Izzi Claudia , Barbon Alessandro , Kretz Rebekka , Sander Thomas , Barlati Sergio 
Published: August 2002

AbstractHereditary factors play a major role in the etiology of juvenile absence epilepsy (JAE) that is a common subtype of idiopathic generalized epilepsy (IGE). Sander et al. [1997: Am J Med Genet 74:416–421] reported an allelic association of JAE with the nine‐copy allele of a tetranucleotide repeat polymorphism in the third intron of the kainate‐selective GluR5 receptor gene (GRIK1) and supportive evidence for linkage of IGE to GRIK1 in families of JAE probands. These findings suggest that a major genetic determinant of GRIK1 confers susceptibility to JAE. Assuming that the GRIK1 tetranucleotide repeat polymorphism is unlikely to have functional relevance itself, we have sequenced the coding regions and regulatory sequences of the GRIK1 gene in eight JAE patients who carry the nine‐repeat allele of the GRIK1 tetranucleotide repeat polymorphism to detect a putative functional GRIK1 mutation that is in linkage disequilibrium with the nine‐repeat allele. Seven of them were derived from families showing positive evidence for linkage to GRIK1. Our mutation analysis of coding regions and splice junctions revealed only two silent polymorphisms (A522C and C1173T) out of the five SNPs present in public databases and no mutations affecting protein structure. No significant differences were found in the allele frequencies of the detected polymorphisms between the JAE patients and controls. High levels of sequence conservation were also found in the promoter, in the 5′ and both the 3′ untranslated regions and in the RNA secondary structure involved in the editing reaction. The results presented indicate that mutations in the coding sequences, in the intron‐exon boundaries and in the main regulatory regions of the GRIK1 are not commonly involved in the etiology of JAE. © 2002 Wiley‐Liss, Inc.

Published: August 2002

AbstractUnderstanding the growth pattern in Marfan syndrome is important for prediction of expected growth, prevention of excessive growth by hormone therapy, timing of surgical epiphysiodesis for cessation of growth, and instituting brace treatment for scoliosis. In this study, we analyze growth patterns and generate growth charts for persons with Marfan syndrome. From the charts of 180 clinically diagnosed Marfan patients, longitudinal height and weight measurements were obtained. From this data, growth charts and growth velocity charts were generated for males and females. Skeletal maturation was studied by determining the Risser signs from the x‐rays of 71 males and 56 females. From 22 female patients, age of menarche was available and retrieved either by reviewing the charts or contacting the patients. Mean length at birth was 53 ± 4.4 cm for males and 52.5 ± 3.5 cm for females. Mean final height was 191.3 ± 9 cm for males and 175.4 ± 8.2 cm for females. Mean birth weight was 3.51 ± 0.74 kg for males and 3.48 ± 0.68 kg for females. The puberty‐associated peak in growth velocity was 2.4 years earlier than the gender‐matched general population for males with Marfan syndrome and 2.2 years earlier for females. Age of menarche was 11.7 ± 2 years of age, which is also early compared to the general population. This study suggests that the growth spurt and pubertal skeletal maturation occur early in Marfan syndrome. The growth curves generated should help more accurately predict adult stature, as well as monitor progression toward it. © 2002 Wiley‐Liss, Inc.
No association of the dopamine transporter gene 3′ VNTR polymorphism with ADHD subtypes in a population sample of twins
Authors: Todd Richard D. , Jong Yuh‐Jiin I. , Lobos Elizabeth A. , Reich Wendy , Heath Andrew C. , Neuman Rosalind J. 
Published: August 2002

AbstractDopamine pathway genes have been the subject of a variety of studies testing the association of candidate genes and liability for attention‐deficit hyperactivity disorder (ADHD). Due to the known effects of stimulant medications such as methylphenidate on the dopamine transporter, a variety of case control and family‐based transmission distortion genetic studies of ADHD have focused on DAT1 polymorphisms. The most widely reported positive finding has been with a variable number of tandem repeats (VNTR) polymorphism of unknown function in the 3′ untranslated region of the DAT1 gene. In this report, we test for association of alleles of this polymorphism with ADHD using population‐derived samples of twins. We use the transmission disequilibrium test and ADHD subtypes defined by both DSM‐IV and latent class criteria. We fail to demonstrate any significant association or trend for association of any of the VNTR alleles with any of the variously defined ADHD subtypes. © 2001 Wiley‐Liss, Inc.
Evidence for postjunctional serotonin (5‐HT1) receptors in the trigeminocervical complex
Authors: Goadsby Peter J. , Akerman Simon , Storer R. James 
Published: August 2002

AbstractUnits linked to stimulation of the superior sagittal sinus were identified and recorded from in the trigeminocervical complex of the anesthetized cat. Iontophoresis of glutamate NMDA receptor agonists increased the baseline‐firing rate of these neurons. Coejection of sumatriptan, 4991W93, or ergometrine resulted in a significant reduction in NMDA agonist‐induced increases in firing. These data establish the existence of triptan‐sensitive (5‐HT1) receptors on postsynaptic central trigeminal neurones.
Synthesis and characterization of pH‐sensitive networks containing degradable poly(1,3‐dioxolane) segments
Authors: Du Juan , Peng Yuxing , Zhang Tingting , Ding Xiaobin , Zheng Zhaohui 
Published: August 2002

AbstractpH‐sensitive networks were obtained by radical copolymerization of telechelic poly(1,3‐dioxolane) (PDXLDA) with acrylic acid (AA). PDXLDA was synthesized by acrylation of the corresponding dihydroxylated polyacetal (polyDXL) with AA in pyridine. The copolymer networks of poly(AA‐b‐DXL) showed pH sensitivity due to —COOH groups, which are insoluble in any solvents, but can swell in water or good solvents. The swelling behavior is closely related to the solvents and is composition‐dependent. The networks containing polyDXL segments can be decrosslinked under acidic conditions due to the low ceiling temperature of polyDXL. After degradation, the linear segments of polyDXL became cycled molecules. The networks' structure, swelling behavior, and degradation were characterized by Fourier transform infrared spectroscopy, differential scanning calorimetry, GC–MS analysis, and swelling data. This kind of material can be potentially used in biosystems, such as in intelligent drug‐delivery systems. © 2002 Wiley Periodicals, Inc. J Appl Polym Sci 83: 1678–1682, 2002

Published: August 2002

AbstractThe turbulent drag reduction characteristics in a rotating disk apparatus were investigated by using polysaccharide guar gum in deionized water. The ultrasonic degradation method was adopted to obtain different molecular weight fractions of guar gum for this study. The stability of guar gum over time was observed to be better than the typical synthetic water‐soluble drag reducers [e.g., poly(ethylene oxide)]. A linear correlation between polymer concentration and the concentration/(drag reduction) for different molecular weights of guar gum was obtained, and the universal drag reduction curve for the guar gum/deionized water system was constructed. © 2002 Wiley Periodicals, Inc.

Role of chain length in degradation process (chain breakdown)
Authors: Vainstein E. F. , Zaikov G. E. 
Published: August 2002

AbstractThe role of molecular weight of a chain in the chain breakdown in diluted solution at a constant concentration of chain molecules and constant temperature is discussed theoretically using the methods of the theory of the activated complex and kinetics of cooperative processes. The reaction starts at the certain molecular weight of the chain. The chain breakdown is the flat increasing function of the chain molecular weight. This function has a limit when chain molecular weight approaches infinity. Such dependence is explained by the increase of flexibility (following two theories) and increase of extra entropy of molecules of different sizes (following kinetics of cooperative processes. Unequal reactivity of chemically identical active centers links to the dependence of chain flexibility on the location of the more flexible part (place of reaction) of the chain. © 2002 Wiley Periodicals, Inc.

Deposition of polypyrrole on microporous filtration membranes at air/water interface
Authors: Pyo Myoungho , Cho Chulae 
Published: August 2002

AbstractMicrofiltration membranes were utilized as a template for the preparation of polypyrrole films at the air/water interface. Unlike the formation of polypyrrole tubules (or fibrils) when the membranes are soaked in polymerization media, chemical polymerization on the membrane at the interface resulted in the film formation on the membrane surface in contact with polymerization media, without remaining open micropores. Investigations of electrochemical responses with anthraquinone‐2‐sulfonate and Fe(CN) on fully reduced or oxidized polypyrrole as well as studies of conductivity changes with polypyrrole deposition were carried out to confirm this behavior. Complete coverage of one side of a microfiltration membrane with a polypyrrole layer, remaining micropore walls, and the other side of a membrane intact, could be useful in various applications because it allows further electrochemical treatment/measurements utilizing these open micropores straightforward. © 2002 Wiley Periodicals, Inc.

Kinetic studies of crease‐resistant finishing process for cotton fabrics with DMEU/MMEU prepolymer mixture
Authors: Shih Chung‐Yang , Huang Kuo‐Shien 
Published: August 2002

AbstractThe kinetics of the crease‐resistant finishing process for cotton fabrics with DMEU/MMEU prepolymer mixture are studied. The DMEU/MMEU prepolymer resin is made from ethylene urea (EU) and paraformaldehyde (PF) with different mole ratios. The results show that the nitrogen content in the treated fabrics and the reaction rate constant increases with curing temperature and PF mole ratio. The treated fabrics with more PF in the source material have smaller Ea, Δ H*ast;, and ΔS*. The ΔG* was independent of the mole ratio in the source material, but it increases with curing temperature. © 2002 Wiley Periodicals, Inc. J Appl Polym Sci 85: 509–513, 2002
Effect of bonding agents on styrene butadiene rubber–aluminum powder composites
Authors: Vinod V. S. , Varghese Siby , Kuriakose Baby 
Published: August 2002

AbstractEffects of various bonding agents—such as the hexamethylene tetramine–resorcinol system (HR), bis[3‐ (triethoxysilyl) propyl] tetra sulfide (Si‐69), and cobalt naphthenate (CoN)—on the mechanical properties of aluminum powder filled styrene butadiene rubber composites were studied, giving emphasis on concentration of bonding agent and loading of aluminum powder. Shore A hardness, modulus, tensile strength, tear strength, heat buildup, etc., were increased by the loading of aluminum powder, and the presence of bonding agents again increased these properties. Rebound resilience and elongation at break were decreased by the addition of aluminum powder. Equilibrium swelling studies showed an improved adhesion between aluminum powder and styrene butadiene rubber (SBR) in presence of bonding agents. Among the various bonding agents used in this study, silane coupling agent (Si‐69) and hexamethylene tetramine–resorcinol (HR) system were found to be better for aluminum powder filled SBR vulcanizates. © 2002 Wiley Periodicals, Inc.

Synthesis and characterization of bisitaconimides. I
Authors: Solanki Anjali , Choudhary Veena , Varma I. K. 
Published: August 2002

AbstractThis article describes the synthesis and characterization of bisitaconimides on the basis of 4,4′‐diaminodiphenylether, 2,2′‐bis[4‐(4‐aminophenoxy)phenyl]propane, 1,3‐bis(4‐aminophenoxy)benzene, and 1,4‐bis (4‐aminophenoxy)benzene. Isomerization of the itaconimides to citraconimides (varying in the range of 25–40%) was observed during synthesis. The curing exotherm and thermal stability of the cured resins depended on the backbone structure of itaconimides. The curing exotherm immediately followed the melting endotherms. These resins cured at lower temperatures than bismaleimides but thermal stability of cured bismaleimides was higher than bisitaconimides. © 2002 Wiley Periodicals, Inc.

Published: August 2002

AbstractFour polyelectrolyte complexes were formed through the self‐assembly of poly‐N‐ethyl‐N,N‐ dimethylamino ethyl methacrylate (PEDEM) and poly‐ N‐ethyl‐4‐vinylpyridinium (PEVP) cations with methyl orange (MO) and metanil yellow (MY) anions in water. The FTIR spectra showed that the assembly was formed chiefly through electrostatic force and hydrophobic interaction between polyelectrolytes and organic dyes without new bonds emerging. The fluorescence spectra revealed that the emission waves of the complexes of PEDEM‐MY and PEDEM‐MO in alcohol were blue‐shift in comparison with those of dyes in alcohol, and the emission waves of the PEVP‐MY and PEVP‐MO complexes in alcohol were red‐shift in comparison with those of dyes in alcohol. The structure of the complexes in solid state were also investigated by differential thermal analysis (DTA) and X‐ray diffraction experiments. It was proved that the complexes were new materials formed through weak interactions. © 2002 Wiley Periodicals, Inc. J Appl Polym Sci 85: 638–644, 2002
Processing characteristics and physicomechanical properties of natural rubber and liquid natural rubber blends
Authors: Okieimen F. E. , Akinlabi A. K 
Published: August 2002

AbstractInvestigations into the processing characteristics and physicomechanical properties of natural rubber (NR) modified with liquid natural rubber (LNR) were carried out. Liquid natural rubber samples (of different molecular weights) were first produced by depolymerization of natural rubber latex (NRL), using nitrobenzene as the depolymerizing agent to lower molecular weight rubbers. The LNRs produced were then mixed with natural rubber in various proportions. The NR/LNR blends showed better processing characteristics by having higher scorch time and lower cure rate, higher molecular mass between crosslinking resulting from the lower volume fraction of the LNR, and good solubility properties; and marginal differences in shear modulus, crosslinking densities, Mooney viscosity, plasticity, and the plasticity retention index compared to properties of an unmodified NR. © 2002 Wiley Periodicals, Inc.

Published: August 2002

AbstractElectrochemical copolymerization of pyrrole and indole was performed galvanostatically in a solvent of acetonitrile (AN)/water (vol %: 99/1). The product obtained was characterized by cyclic voltammetry and infrared spectroscopy. The influence of the monomer feed ratio of pyrrole and indole on the synthesis of the copolymer was investigated. The amount of pyrrole units in the copolymer chain increased with increase of the concentration of the pyrrole monomer in the solution. The results showed that the electrochemical activity of the copolymer was improved as the incorporation of pyrrole units increased. Thermogravimetric analysis was carried out to investigate the properties of the copolymer. © 2002 Wiley Periodicals, Inc. J Appl Polym Sci 85: 814–820, 2002
