Background

Lateral epicondylitis is a common work‐related musculoskeletal disorder. The objective of this study was to identify risk factors associated with lateral epicondylitis among active workers.

Methods

Seven‐hundred thirty‐three workers in 12 Washington worksites participated in structured interviews, physical examinations, and individual exposure assessments of biomechanical and psychosocial factors. Multivariable logistic modeling was used.

Results

Thirty‐eight subjects (5.2%) had lateral epicondylitis. Age (36–50 years‐old), being female, and low social support at work were significant risk factors. Frequency of forceful exertion (≥5 vs. <1 times/min (OR 5.17, 95%CI 1.78–15.02), and ≥1 to <5 vs. <1 (OR 4.47, 95%CI 1.57–13.71)) and forearm supination at ≥45° for ≥5% of the time with high lifting force (OR = 2.98, 95% CI 1.18–7.55) were significant physical load factors.

Conclusions

Frequency of forceful exertion or a combination of forearm supination and forceful lifting were significant physical factors and should be considered for prevention strategies. Am. J. Ind. Med. 52:479–490, 2009. © 2009 Wiley‐Liss, Inc.

Mit H2O2 reagieren die Komplexe 1 zu den Bis(μ‐oxo)dinickel(III)‐Komplexen 2, in denen die Xylyl‐Brücke des Liganden unter Bildung von 3 hydroxyliert werden kann. Kinetische Studien identifizieren den Hydroxylierungsprozess als eine elektrophile aromatische Substitution. Die geringere Reaktivität als bei entsprechenden μ‐η2:η2‐Peroxo‐Dikupfer(II)‐Komplexen lässt sich mit ungünstigen entropischen Effekten erklären.

Published: April 2009

Easy come, easy go? Transport resistances on particle surfaces are important for mass transfer in nanoporous materials and bulk diffusion in crystals. Interference microscopy and IR micro‐imaging are shown to be excellent tools for determining such transport resistances. By studying short‐chain‐length alkane guest molecules in crystals of the metal–organic framework compound Zn(tbip) a data collection of surface permeabilities is established.

Efforts Toward the Direct Experimental Characterization of Enzyme Microenvironments: Tyrosine100 in Dihydrofolate Reductase
Authors: Groff Dan , Thielges Megan C. , Cellitti Susan , Schultz Peter G. , Romesberg Floyd E.
Published: April 2009

State secrets: Site‐specific deuteration and FTIR studies reveal that Tyr100 in dihydrofolate reductase plays an important role in catalysis, with a strong electrostatic coupling occuring between Tyr100 and the charge that develops in the hydride‐transfer transition state (see picture, NADP+ purple, Tyr100 green). However, relaying correlated motions that facilitate catalysis from distal sites of the protein to the hydride donor may also be involved.

Published: April 2009

Stereocontrolled access to the hexacyclic core of FD‐594 has been achieved. The key steps include the intramolecular SNAr reaction for construction of the densely functionalized xanthone skeleton, the stereoselective lactone cleavage using a chiral nucleophile to induce the axial stereochemistry, and the SmI2‐mediated pinacol cyclization for the stereocontrolled conversion of axially chiral biaryl dialdehyde into the corresponding trans diol.

Sweets for my sweet! Efficient synthesis of the deoxysugar part of versipelostatin (VST) was achieved by direct and stereoselective glycosidation of the reduced VST aglycon. Comparison of the synthetic and natural VST products using NMR indicate that VST has a β‐d‐digitoxose‐(1,4)‐α‐l‐oleandrose‐(1,4)‐β‐d‐digitoxose trisaccharide. A biological assay indicates that the deoxyoligosaccharide unit of the synthetic glycoside is important for biological activity.

Efficient synthesis of the deoxysugar part of versipelostatin (VST) was achieved by direct and stereoselective glycosylation of the reduced VST aglycon. Activation of 2‐deoxyglycosyl imidate with IBr under basic conditions enables α‐selective glycosylation of β‐2‐deoxylglycosides without anomerization. Comparison of the synthetic and natural VST products using NMR indicates that versipelostatin has a β‐D‐digitoxose‐(1,4)‐α‐L‐oleandrose‐(1,4)‐β‐D‐digitoxose trisaccharide. In addition, results of a biological assay indicate that the deoxyoligosaccharide unit of the synthetic glycoside was important for biological activity of the compound.
The Role of Organic Glasses in cis/trans Photoisomerization at Low Temperatures
Authors: Zhao Yao‐Peng , Yang Lan‐Ying , Simmons Charles J. , Liu Robert S. H.
Published: April 2009

Into the looking glass! Low temperature photoisomerization studies on some arenes have been studied in different organic glasses. The results are consistent with a possible softening of the glass and offer an explanation for the mechanism of photoisomerization in a confined medium.

magnified image

Low temperature photoisomerization of stilbene and 1,4‐diphenyl‐1,3‐butadiene derivatives was found to vary depending on the organic glass employed in such studies. Examination of the combined results showed that the variation was more likely to arise from the rigidity of the organic glass at the temperature of irradiation rather than the composition of the organic glass; that is, the observed results are consistent with the possible softening of the glass that surrounds the excited substrate in the same manner as detected in the photolysis of ethyl iodide reported by Porter and co‐workers. These observations successfully account for the apparent “disagreement” of reports from the Hawaii and the Florida State groups on the mechanism of photoisomerization in low temperature glasses.

Published: April 2009

Mit dem Berechnungsverfahren der DIN V 18599 liegt ein umfassendes Berechnungsmodell für die energetische Bewertung von Gebäuden vor. Der große Umfang der Verfahren stellt auch an die softwaretechnischen Umsetzungen für die Planungspraxis hohe Anforderungen. Das Fraunhofer‐Institut für Bauphysik hat hierzu den Rechenkern ibp18599kernel entwickelt, der zwischenzeit‐lich von zahlreichen Softwarehäusern für Endanwendungsprogramme zur energetischen Bewertung und Erstellung von Energieausweisen eingesetzt wird. Dieser “Rechenmotor” unterliegt einer steten Qualitätskontrolle zur Sicherstellung der Berechnungsgenauigkeit. Der vorliegende Aufsatz stellt den Prozess der Qualitätssicherung anhand eines neuen Validierungsbeispiels in Form eines komplexen Verwaltungsgebäudes vor. Die Fallstudie kann auch zur Validierung anderer Berechnungssysteme, die nicht auf dem Rechenkern basieren, genutzt werden.
Die Ermittlung des Jahresnutzkühlenergiebedarfs in Bürogebäuden mit dem Berechnungsverfahren nach Energieeinsparverordnung 2007 bzw. DIN V 18599
Authors: Merkel Karlheinz , Haupt Wolfram , Tutsch Joram , Pültz Gunter , Wolf Stefan
Published: April 2009

Die seit 2007 gültige Energieeinsparverordnung (EnEV) schreibt für Bürogebäude eine gesamtheitliche Bilanzierung des Energiebedarfs vor, so dass neben dem Heizwärmeverbrauch und dem Energieverbrauch für Lüftungsanlagen erstmals auch der Kühlenergieverbrauch und der Stromverbrauch für Beleuchtung zu berücksichtigen ist. Die vorliegende Studie fokussiert auf den Jahreskühlenergieverbrauch von Büroräumen, welcher neben den Rechenregeln nach EnEV 2007 bzw. DIN V 18599 auch mit Hilfe der Algorithmen in der VDI 2067 oder mittels dynamischer, thermischer Simulationen ermittelt werden kann. Hierzu wird der Jahreskühlenergiebedarf für einen typischen Büroraum mit unterschiedlichen Fassadentypen nach den verschiedenen Verfahren berechnet, um Unterschiede aufzuzeigen. Abschließend wird exemplarisch der Einfluss des dem jeweiligen Verfahren zugrundeliegenden Außenklimas aufgezeigt.

Authors: Popper Rudolf , Niemz Peter
Published: April 2009

An 21 heimischen und 11 überseeischen Holzarten wurde die Gleichgewichtsfeuchte bei 20 °C und 35, 50, 65, 80 und 95 % relativer Luftfeuchtigkeit experimentell in der Adsorptionsphase bestimmt. Aufbauend auf den experimentell bestimmten Mittelwerten wurden mit dem Hailwood‐Horrobin‐Modell (HH‐Modell) ausgewählte Parameter wie Fasersättigungsfeuchte, mono‐ und polymolekulare Sorption, spezifische Oberfläche des Sorbenten, hypothetisches Molekulargewicht des Sorbenten sowie Unzugänglichkeit des Sorbenten zum Sorbat berechnet. Zusätzlich wurden Tabellen für die Gleichgewichtsfeuchte bei 20 °C und in 2‐%‐Schritten abgestufter relativer Luftfeuchtigkeit berechnet. Die mittels des HH‐Modells berechnete Fasersättigungsfeuchte liegt für alle geprüften Holzarten im Bereich zwischen 22 bis 36 %, im Mittel bei ca. 30 %. Es treten erhebliche Abweichungen zwischen den einzelnen Holzarten in der Fasersättigungsfeuchte auf. Die Tendenzen für die Kenngrößen der Sorptionsanalyse wurden aufgezeigt.
Resonance light scattering spectrometric study of poly diallyldimethylammonium chloride–antibody–antigen system
Authors: Li Juan , Li Xiaozhou , Tang Jieli , Kang Jing , Zhang Yihua
Published: April 2009

The interaction of antigen (Ag) and antibody (Ab) with poly diallyldimethylammonium chloride (PDDA) in aqueous solutions has been studied by optical absorption and resonance light‐scattering (RLS) spectroscopies. The formation of the three‐component‐complex is due to aggregates of Ab or Ag with PDDA by electrostatic interaction and aggregates of Ab with Ag by immunoreaction. The influences of some experimental factors, including incubation time, pH value, concentration of PDDA and concentration of Ab, on the aggregation process have also been studied. A linear relationship between the concentration of Ag and the RLS intensity was found. Under the optimal conditions, for a given concentration of Ab (4.6 µg/mL), the enhancement of RLS intensity is in proportion to the concentration of Ag in the range 0.03–0.83 µg/mL. The RLS could, in combination with immunoassay, be a rapid and sensitive detection method for Ag. Copyright © 2009 John Wiley & Sons, Ltd.
Scavenging of superoxide anion radical and hydroxyl radical by novel thiazolyl‐thiazolidine‐2,4‐dione compounds
Authors: Bozdağ‐Dündar Oya , Gürkan Selen , Aboul‐Enein Hassan Y. , Kruk Irena , Kładna Aleksandra
Published: April 2009

The antioxidant behavior of a series of new synthesized substituted thiazolyl‐thiazolidine‐2,4‐dione compounds (TZDs) was examined using chemiluminescence and electron paramagnetic resonance spin trapping techniques. 5,5‐Dimethyl‐1‐pyrroline‐N‐oxide (DMPO) was used as the spin trap. The reactivity of TZDs with superoxide anion radical (O) and hydroxyl radical (HO•) was evaluated using potassium superoxide/18‐crown‐6 ether dissolved in dimethylsulfoxide, and the Fenton‐like reaction (Fe2+ + H2O2), respectively. The results showed that TZDs efficiently inhibited light emission from the O generating system at a concentration of 0.05–1 mmol L−1 (5–94% reductions were found at 1 mmol L−1 concentration). The TZD compounds showed inhibition of HO•‐dependent DMPO–OH spin adduct formation from DMPO (the amplitude decrease ranged from 8 to 82% at 1 mmol L−1 concentration). The findings showed that examined TZDs had effective activities as radical scavengers. Copyright © 2009 John Wiley & Sons, Ltd.
A rational design approach for amino acid supplementation in hepatocyte culture
Authors: Yang Hong , Roth Charles M. , Ierapetritou Marianthi G.
Published: April 2009

Improvement of culture media for mammalian cells is conducted via empirical adjustments, sometimes aided by statistical design methodologies. Here, we demonstrate a proof of principle for the use of constraints‐based modeling to achieve enhanced performance of liver‐specific functions of cultured hepatocytes during plasma exposure by adjusting amino acid supplementation and hormone levels in the medium. Flux balance analysis (FBA) is used to determine an amino acid flux profile consistent with a desired output; this is used to design an amino acid supplementation. Under conditions of no supplementation, empirical supplementation, and designed supplementation, hepatocytes were exposed to plasma and their morphology, specific cell functions (urea, albumin production) and lipid metabolism were measured. Urea production under the designed amino acid supplementation was found to be increased compared with previously reported (empirical) amino acid supplementation. Not surprisingly, the urea production attained was less than the theoretical value, indicating the existence of pathways or constraints not present in the current model. Although not an explicit design objective, albumin production was also increased by designed amino acid supplementation, suggesting a functional linkage between these outputs. In conjunction with traditional approaches to improving culture conditions, the rational design approach described herein provides a novel means to tune the metabolic outputs of cultured hepatocytes.

A two‐phase partitioning airlift bioreactor for the treatment of BTEX contaminated gases
Authors: Littlejohns Jennifer V. , Daugulis Andrew J.
Published: April 2009

This investigation characterizes a novel 11 L airlift two‐phase partitioning bioreactor (TPPB) for the treatment of gases contaminated with a mixture of benzene, toluene, ethylbenzene, and o‐xylene (BTEX). The application of the TPPB technology in an airlift bioreactor configuration provides a novel technology that reduces energy intensity relative to traditional stirred tank TPPB configurations. The addition of a solid second phase of silicone rubber beads (10%, v/v) or of a liquid second phase of silicone oil (10%, v/v) resulted in enhanced performance of the airlift bioreactor relative to the single phase case, with 20% more BTEX being removed from the gas phase during an imposed transient loading. During a 4 h loading step change of three times the nominal loading (60 g m−3 h−1), overall removal efficiencies for the airlift TPPBs containing a liquid or solid phase remained above 75%, whereas the single phase airlift had an overall removal efficiency of 47.1%. The airlift TPPB containing a silicone rubber second phase was further characterized by testing performance during steady‐state operation over a range of loadings and inlet gas flow rates in the form of a 32 factorial experimental design. Optimal operating conditions that avoid oxygen limitations and that still have a slow enough gas flow rate for sufficient BTEX transfer from the gas phase to the working volume are identified. The novel solid–liquid airlift TPPB reduces energy inputs relative to stirred tank designs while being able to eliminate large amounts of BTEX during both steady‐state and fluctuating loading conditions.

Energy from algae using microbial fuel cells
Authors: Velasquez‐Orta Sharon B. , Curtis Tom P. , Logan Bruce E.
Published: April 2009

Bioelectricity production from a phytoplankton, Chlorella vulgaris, and a macrophyte, Ulva lactuca was examined in single chamber microbial fuel cells (MFCs). MFCs were fed with the two algae (as powders), obtaining differences in energy recovery, degradation efficiency, and power densities. C. vulgaris produced more energy generation per substrate mass (2.5 kWh/kg), but U. lactuca was degraded more completely over a batch cycle (73 ± 1% COD). Maximum power densities obtained using either single cycle or multiple cycle methods were 0.98 W/m2 (277 W/m3) using C. vulgaris, and 0.76 W/m2 (215 W/m3) using U. lactuca. Polarization curves obtained using a common method of linear sweep voltammetry (LSV) overestimated maximum power densities at a scan rate of 1 mV/s. At 0.1 mV/s, however, the LSV polarization data was in better agreement with single‐ and multiple‐cycle polarization curves. The fingerprints of microbial communities developed in reactors had only 11% similarity to inocula and clustered according to the type of bioprocess used. These results demonstrate that algae can in principle, be used as a renewable source of electricity production in MFCs. Biotechnol. Bioeng. 2009;103: 1068–1076. © 2009 Wiley Periodicals, Inc.

Influence of molecular parameters and increasing magnetic field strength on relaxivity of gadolinium‐ and manganese‐based T1 contrast agents
Authors: Caravan Peter , Farrar Christian T. , Frullano Luca , Uppal Ritika
Published: April 2009

Simulations were performed to understand the relative contributions of molecular parameters to longitudinal (r1) and transverse (r2) relaxivity as a function of applied field, and to obtain theoretical relaxivity maxima over a range of fields to appreciate what relaxivities can be achieved experimentally. The field‐dependent relaxivities of a panel of gadolinium and manganese complexes with different molecular parameters, water exchange rates, rotational correlation times, hydration state, etc. were measured to confirm that measured relaxivities were consistent with theory. The design tenets previously stressed for optimizing r1 at low fields (very slow rotational motion; chelate immobilized by protein binding; optimized water exchange rate) do not apply at higher fields. At 1.5T and higher fields, an intermediate rotational correlation time is desired (0.5–4 ns), while water exchange rate is not as critical to achieving a high r1. For targeted applications it is recommended to tether a multimer of metal chelates to a protein‐targeting group via a long flexible linker to decouple the slow motion of the protein from the water(s) bound to the metal ions. Per ion relaxivities of 80, 45, and 18 mM−1 s−1 at 1.5, 3 and 9.4 T, respectively, are feasible for Gd3+ and Mn2+ complexes. Copyright © 2009 John Wiley & Sons, Ltd.
Bilateral projections from rat MI whisker cortex to the neostriatum, thalamus, and claustrum: Forebrain circuits for modulating whisking behavior
Authors: Alloway Kevin D. , Smith Jared B. , Beauchemin Kyle J. , Olson Michelle L.
Published: April 2009

In rats, whisking behavior is characterized by high‐frequency synchronous movements and other stereotyped patterns of bilateral coordination that are rarely seen in the bilateral movements of the limbs. This suggests that the motor systems controlling whisker and limb movements must have qualitative or quantitative differences in their interhemispheric connections. To test this hypothesis, anterograde tracing methods were used to characterize the bilateral distribution of projections from the whisker and forepaw regions in the primary motor (MI) cortex. Unilateral tracer injections in the MI whisker or forepaw regions revealed robust projections to the corresponding MI cortical area in the contralateral hemisphere. Both MI regions project bilaterally to the neostriatum, but the corticostriatal projections from the whisker region are denser and more evenly distributed across both hemispheres than those from the MI forepaw region. The MI whisker region projects bilaterally to several nuclei in the thalamus, whereas the MI forepaw region projects almost exclusively to the ipsilateral thalamus. The MI whisker region sends dense projections to the contralateral claustrum, but those to the ipsilateral claustrum are less numerous. By contrast, the MI forepaw region sends few projections to the claustrum of either hemisphere. Bilateral deposits of different tracers in MI revealed overlapping projections to the neostriatum, thalamus, and claustrum when the whisker regions were injected, but not when the forepaw regions were injected. These results suggest that the bilateral coordination of the whiskers depends, in part, on MI projections to the contralateral neostriatum, thalamus, and claustrum. J. Comp.
