Identifying Risk Factors for Underimmunization by Using Geocoding Matched to Census Tracts: A Statewide Assessment of Children in Hawaii
Authors: Whitehead Sara J. , Cui Kate X. , De Anindya K. , Ayers Tracy , Effler Paul V. 
Published: August 2007

OBJECTIVE. Obtaining childhood immunization coverage data for small geographic areas is difficult and resource-intensive, especially in the absence of comprehensive immunization registries. To identify factors that are associated with delayed immunization, we collected school-entry immunization records statewide and used geocoding to link to publicly available census tract sociodemographic data.METHODS. Immunization records were reviewed for children who were enrolled in all public and private school kindergarten programs in Hawaii in the 2002–2003 school year; immunization status at the time of the second birthday was determined. The main outcome variable was up-to-date status for the 4:3:1:3:3 vaccination series (4 doses of diphtheria-tetanus-pertussis, 3 doses of polio, 1 dose of measles-mumps-rubella, 3 doses of Haemophilus influenzae type b, and 3 doses of hepatitis B vaccines). Children's home addresses were geocoded to census tracts; coverage rates by tract were mapped, and sociodemographic data from Census 2000 files were used to identify factors that were associated with delays in immunization.RESULTS. Records were obtained for 15275 of 15594 children registered in Hawaii kindergartens. Overall, 78% had completed their 4:3:1:3:3 series by their second birthday. Risk factors for delayed immunization included delayed immunization at 3 months of age, living in Maui County, living in a neighborhood where a low proportion of adults had postsecondary education, and living in a neighborhood where a high proportion of households spoke a language other than English at home. The majority (80%) of underimmunized children would have required only 1 additional visit to bring them up-to-date.CONCLUSIONS. Retrospective review of kindergarten-entry immunization data revealed geographic areas with lower immunization coverage, and geocoding to census tracts identified associated sociodemographic risk factors. This is a practical method for state or city health departments to identify pockets of need and to direct resources appropriately.

Published: August 2007

Abstract
The harmful effects of surfactants to the environment are well known. We were interested in investigating their potential toxicity in a pure culture of Acinetobacter junii, a phosphate (P)-accumulating bacterium. Results showed a high acute toxicity of sodium dodecyl sulfate (SDS) and hexadecyltrimethylammonium bromide (HDTMA) against A. junii. The estimated EC50 values of the HDTMA for the inhibition of CFUs in the pure culture of A. junii was 3.27 ± 1.12 × 10−7 mol L−1 and for the inhibition of the P-uptake rates 2.47 ± 0.51 × 10−6 mol L−1. For SDS, estimated EC50 values for the inhibition of CFUs in the pure culture of A. junii was 5.00 ± 2.95 × 10−6 mol L−1 and for the inhibition of the P-uptake rates 3.33 ± 0.96 × 10−4 mol L−1. The obtained EC50 values in the standardised yeast toxicity test using Saccharomyces cerevisiae were 3.03 ± 0.38 × 10−4 and 4.33 ± 0.32 × 10−5 mol L−1 for SDS and HDTMA, respectively. These results emphasized the need to control concentrations of surfactants entering the activated sludge system. The negative effects of these toxicants could greatly decrease populations of P-accumulating bacteria, as well as eukaryotic organisms, inhabiting activated sludge systems, which in turn could result in the decrease of the system efficiency.

Abstract
Little is known about the extra- and intracellular stimuli inducing renal stem/progenitor cells to develop into three-dimensionally structured tubules. To study this specific development in a controlled environment, we used an advanced culture technique. Embryonic tissue derived from neonatal rabbit kidney was placed in a perfusion culture container at the interface of an artificial interstitium made of a polyester fleece. Culture was carried out in chemically defined Iscove’s Modified Dulbecco’s Medium (IMDM) for 13 days. Development of tubules was histochemically detected on cryosections labeled with Soybean Agglutinin (SBA). The experiments showed that aldosterone exerts a specific tubulogenic effect. Application of aldosterone (1 × 10−7 M) raised numerous SBA-labeled tubules, while in the absence of the steroid hormone the development of tubules was lacking. Specificity of hormone action was analyzed by the use of aldosterone antagonists. Administration of spironolactone (1 × 10−4 M) and canrenoate (1 × 10−5 M) completely inhibited the development of tubules. Finally, disrupting the intracellular molecular complex of the mineralocorticoid receptor (MR) and heat shock proteins by geldanamycin (2 μg/ml) prevented the development of tubules. Our results suggest that the tubulogenic effect induced by aldosterone is attributed to both hormone binding and an undisturbed intracellular response of the MR.
Measurement Decisions for Clinical Assessment of Limb Volume Changes in Patients With Bilateral and Unilateral Limb Edema
Authors: Mayrovitz Harvey N , Macdonald John , Davey Suzanne , Olson Kelly , Washington Ezella 
Published: August 2007

Background and Purpose
Therapy-related changes in limb volumes often are estimated using summated segmental volumes based on adjacent circumference measurements. The purposes of this study were: (1) to determine the effect of different segment lengths on calculated volume reductions after complete decongestive therapy and (2) to determine the effect of excluding posttherapy control limb volumes on calculated reductions in edema volume in patients with unilateral limb lymphedema.

Subjects
This two-part retrospective study was conducted using data from patients with bilateral leg lymphedema (n=70) and data from patients with unilateral arm lymphedema (n=75) and patients with unilateral leg lymphedema (n=45).

Methods
For the bilateral leg lymphedema group, pretreatment to posttreatment changes in limb volume were determined using segment lengths of 4, 8, and 12 cm. For the unilateral lymphedema group, pretreatment to posttreatment changes in edema volume were determined and compared using or not using posttreatment control limb volumes.

Results
Bilateral leg volume changes were similar for all segment lengths but not significantly different from each other. Unilateral edema volume changes were significantly overestimated in both arms and legs when posttherapy control limb volumes were not used.

Discussion and Conclusion
The results indicate that segment lengths of 4 cm generally are not needed to obtain adequate estimates of leg volume changes. Both limb volumes should be measured to properly assess therapeutic outcomes in patients with unilateral limb lymphedema.
Endoscopic Flexor Hallucis Longus Decompression: A Cadaver Study
Authors: Keeling John J. , Guyton Gregory P. 
Published: August 2007

Background New indications for arthroscopy are being considered because arthroscopy limits incision size and potentially decreases operative morbidity. This cadaver study investigated the utility of performing an all-endoscopic flexor hallucis longus (FHL) decompression. Methods Eight fresh-frozen cadaver legs were used. In the simulated prone position with large joint arthroscopic equipment, posterolateral and posteromedial portals were used to perform posterolateral talar process bony excision and FHL sheath debridement and release. We noted the integrity of the sural nerve, FHL tendon, and medial tibial neurovascular bundle. After open dissection, values for sural nerve distance to the posterolateral portal, the amount of FHL sheath released and the proximity of the arthroscopic instrumentation to the medial tibial neurovascular structures were recorded. Results Three of eight FHL tendons were injured during the attempted FHL release. Furthermore, no FHL sheath was completely released down to the level of the sustentaculum. Although posterolateral portal placement was on average 12.1 mm from the sural nerve, it was only 6.1 mm from the lateral calcaneal branch of the sural nerve. Moreover, in all cases the medial calcaneal nerve and first branch of the lateral plantar nerve were closely juxtaposed and in some cases adherent to the FHL fibro-osseous sheath. Conclusions Although os trigonum or posterolateral talar process excision was performed without difficulty, endoscopic release of the FHL tendon proved technically demanding with significant risk to the local neurovascular structures. Given the reliability and low morbidity of open techniques, this cadaver study calls into question the clinical use of complete endoscopic FHL release to the level of the sustentaculum. Moreover, hindfoot endoscopic surgery should be performed by surgeons familiar with open posterior ankle anatomy and experienced in hindfoot endoscopy.

Published: August 2007

Background Although surgery is the standard treatment for hallux valgus, there is insufficient evidence from randomized trials to determine which methods of treatment are most appropriate. Methods One hundred patients with hallux valgus were randomized to a Lindgren (subcapital, transverse, displacement osteotomy) or a distal chevron osteotomy. Outcome measures, such as the American Orthopaedic Foot and Ankle Society (AOFAS) clinical rating for the hallux, EuroQol (EQ-5D) for health-related quality of life, and visual analogue scales (VAS) for pain were used in addition to radiographic parameters. Results The AOFAS score and VAS demonstrated significant improvement in both groups ( p < 0.001) at 1-year followup. There were no differences in outcome between the two procedures regarding patient satisfaction or health-related quality of life as measured by EuroQol (EQ-5D). Patients with limitations in wearing shoes or who were not satisfied with the cosmetic result had a lower EQ-5D. The hallux valgus angle (HVA) and 1–2 intermetatarsal angles (IMA) improved considerably as a result of both operations. The postoperative improvements in HVA, IMA, and 1–2 intermetatarsal distance (IMD) were greater in the Lindgren group. A remaining postoperative HVA of more than 16 degrees was more common in the chevron group. Conclusions Clinical outcomes demonstrated no differences between the procedures, but patients who had a Lindgren osteotomy showed better radiographic correction. Loss of correction was noted in both groups after 3 to 6 years. Neither of the osteotomies is recommended for patients with an HVA of more than 30 degrees or an IMA of more than 15 degrees.
First observation of a hexagonal close packed metastable intermetallic phase between Cu and Al bilayer films
Authors: Cha L. , Scheu C. , Richter G. , Wagner T. , Sturm S. , Rühle M. 
Published: August 2007

Abstract
In this paper we describe the structure and formation of a new intermetallic phase in the Cu – Al system, which has not been reported before. The phase was found in Cu/Al bilayer films, which were deposited at room temperature on (0001) sapphire substrates using molecular beam epitaxy. The interfacial intermetallic phase is 8 nm thick, and possesses a hexagonal close-packed structure. The lattice parameters of the phase gradually increase from the near-Cu-side to the near-Al-side. In parallel with the described lattice expansion, the chemical composition of the interlayer also varies from 27 to 58 Al at.% from the near-Cu-side to the near-Al-side. The formation and microstructural characteristics of this new phase are explained by Hume-Rothery laws and Shockley partial dislocations. In addition, in-situ heating experiments were performed in a transmission electron microscope at ∼600 °C to investigate the thermodynamic stability of this new Cu – Al intermetallic phase. During annealing the intermetallic layer disappears and other known equilibrium intermetallic phases develop. This indicates that this new hexagonal close-packed Cu – Al intermetallic phase is metastable.
Theta-like specimens for measuring mechanical properties at the small-scale: effects of non-ideal loading
Authors: Fuller Edwin R. , Henann David L. , Ma Li 
Published: August 2007

Abstract
As material structures, and devices fabricated from them, shrink to the nano-scale, it is ever more difficult to measure accurately the mechanical properties needed for designing small-scale devices and for assessing reliability. A promising test configuration for localized, small-scale uniaxial tensile measurements is the theta specimen. Stress distributions in this test configuration are examined via finite element analysis. When loaded uniformly with a double-articulating loading platen, a uniform uniaxial stress state is realized in the test gauge. When alternative, more easily realized experimentally, loading configurations are used (i. e., line or point contact), large secondary stresses develop. For each loading configuration, influences of non-ideal load application are elucidated. Two design modifications are considered to mitigate undesirable stresses: a compliant layer and an extended upper loading tab. The latter yields the most favorable stress state and is the most tolerant to non-ideal loading.
Indentation response of single-crystalline GaAs in the nano-, micro-, and macroregime

Published: August 2007

Abstract
Fabrication, handling and processing of wafers of intrinsically brittle and anisotropic single-crystalline GaAs require a high level of control of the material's response to different loading conditions. The present work is focused on the response to hardness indentation. A short overview on the behaviour of (100) GaAs wafers in several doping conditions over a wide range of indentation loads from nano-indentation up to macro-indentation including sharp and blunt indenters is given. Special attention is paid to the pop-in effect in depth-sensing nano-indentation, to the anisotropy of indentation-induced radial crack formation and to the material's crack resistance obtained from the indentation fracture mechanics approach. We have observed that, under certain conditions, the frequency of formation of radial cracks is essentially different for the two in-plane <110> directions. This observation is attributed to the occurrence of two different kinds of dislocations and to the lack of inversion symmetry. The effect turns out to be closely related to a left – right asymmetry in the material removal caused by wire sawing. This insight has paved the way to the optimisation of the process of wire sawing of GaAs single crystals.
Modelling the onset of oxide formation on metal surfaces from first principles
Authors: Ciacchi Lucio Colombi 
Published: August 2007

AbstractThe formation of ultrathin oxide layers on metal surfaces is a non-thermally-activated process which takes place spontaneously at very low temperatures within nanoseconds. This paper reports mechanistic details of the initial oxidation of bare metal surfaces, in particular Al(111) and TiN(001), as obtained by means of first-principles molecular dynamics modelling within the Density-Functional Theory. It is shown that the reactions of bare metal surfaces with O molecules take place according to a “hot-atom” dissociative mechanism which is triggered by the filling of the σ* antibonding molecular orbital and is characterised by a sudden release of a large amount of kinetic energy. This released energy provides a driving force for metal/oxygen place-exchange processes which are responsible for the onset of oxide formation at virtually 0 K and at oxygen coverages well below 1 monolayer (ML). Further simulations of the oxidation reactions reveal that a disordered ultrathin oxide forms on Al(111), whereas a rather ordered structure develops on TiN(001) following a selective oxidation process which leaves clusters of Ti vacancies in the TiN lattice underneath the oxide layer.

The development of boys' preferential pleasure in physical aggression
Authors: Benenson Joyce F. , Carder Hassina P. , Geib‐Cole Sarah J. 
Published: August 2007

AbstractA large body of literature on physical aggression focuses on its maladaptive nature and causes. The current study of 335 children (209 boys, 126 girls), aged 4‐, 5‐, 6‐, and 9‐years, examined a different facet of harmful physical aggression–the development of the pleasure it provides to boys. Two samples of children were included, first 89 boys, then an additional 120 boys and 126 girls. For the first two free response measures, all 209 boys and 126 girls were asked to describe how they played with their three favorite toys and their three favorite playmates, and these descriptions were coded for the presence of physical aggression. Twelve additional structured measures were administered to the second sample of 120 boys and 126 girls. These children were asked to rate how much they enjoyed enacting and viewing on television physical aggression, non‐physically aggressive male sex‐typed roles, and ambiguously sex‐typed roles. Results demonstrated that approximately 50% of boys at all four age levels (and less than 10% of girls) reported that at least one of their three favorite toys was used for inflicting harm through physical aggression on an animate being. Further, with increasing age, boys rated physical aggression in play activities and on television as more enjoyable than alternative male sex‐typed play and television content. Results suggest that advancing understanding of the development of physical aggression requires acknowledging the pleasure it provides to males. Aggr. Behav. 34:154–166, 2008. © 2007 Wiley‐Liss, Inc.
Click Chemistry: Versatility and Control in the Hands of Materials Scientists
Authors: Nandivada H. , Jiang X. , Lahann J. 
Published: August 2007

AbstractThe increasing need for materials with tightly controlled structures will continue to fuel the induction of synthetic organic concepts into materials science. One powerful example is the embracement of “click chemistry” by the materials science community. Because of their high selectivity, near‐perfect reliability, high yields, and exceptional tolerance towards a wide range of functional groups and reaction conditions click reactions have recently attracted increased attention, specifically for use in polymer synthesis as well as for the modification of surfaces and nanometer‐ and mesoscale structures. As outlined in this Review article, click chemistry, such as the CuI‐catalyzed Huisgen 1,3‐dipolar cycloaddition and the Diels–Alder reaction, presents a synthetic concept that lends itself superbly to the controlled preparation of multifunctional materials.
Regional differences in the genetic variability of Finno‐Ugric speaking Komi populations

Published: August 2007

AbstractThe Komi (Komi‐Zyryan) people are one of the most numerous ethnic groups belonging to the Finno‐Ugric linguistic community. They occupy an extensive territory in north Russia to the west of the Ural Mountains, in the northeast of the East European Plain. This is an area of long‐term interactions between Europeans and North Asians. Genetic variability was evaluated in two geographically distinct populations, the Izhemski and Priluzski Komi. We searched for polymorphisms of the TP53 gene (a 16‐bp duplication in intron 3 and three RFLPs: for Bsh1236I at codon 72, for MspI in intron 6, and for BamHI in the 3′ flanking region) and for variable number tandem repeat (VNTR) polymorphisms of locus D1S80 and of the 3′ untranslated region of the gene for apolipoprotein B (ApoB). Some data from our previous studies of TP53, 3′ApoB, and D1S80 variability were involved in the comparison of Komi with other Eastern European populations. Multidimensional scaling analysis of genetic distances was used for the evaluation of genetic relationships between populations. The results revealed some affinity between Priluzski Komi and Eastern Slavonic populations, and significant segregation of Izhemski Komi from other ethnic groups studied. The unique genetic features of Izhemski Komi may have been determined by their ethnogenesis or the pressure of environmental factors, such as special nutrition and adaptation to extreme climatic conditions.

Effect of fiber surface modification on the mechanical properties of sisal fiber‐reinforced benzoxazine/epoxy composites based on aliphatic diamine benzoxazine
Authors: Tragoonwichian Suchada , Yanumet Nantaya , Ishida Hatsuo 
Published: August 2007

AbstractSisal fibers were incorporated into a mixture of benzoxazine and bisphenol A type epoxy resins to form a unidirectionally reinforced composite. Surface modifications of the sisal fibers were carried out with sodium hydroxide, γ‐aminopropyltrimethoxysilane, and γ‐glycidoxypropyltrimethoxysilane. The surface treatments led to changes in the morphology, chemical groups, and hydrophilicity of the fibers. The effect of the fiber surface treatments on the fiber–matrix interfacial adhesion and mechanical properties of the composites were also studied. The results showed that surface treatments with sodium hydroxide and a silane coupling agent led to improved fiber–matrix adhesion; this could be seen in the scanning electron micrographs of the fractured surfaces from mechanical testing and the reduction in the impact strength of the composites made from treated fibers. © 2007 Wiley Periodicals, Inc.
