Determination of the absolute stereochemistry of chiral biphenanthryls in solution phase using chiroptical spectroscopic methods: 2,2′‐Diphenyl‐[3,3′‐biphenanthrene]‐4,4′‐diol
Authors: Petrovic Ana G. , Vick Sarah E. , Polavarapu Prasad L. 
Published: October 2007

AbstractAlthough the exciton coupling model has been widely used in the literature to suggest the absolute configuration using electronic circular dichroism (ECD) spectra, chiral biphenanthryl systems are one group of molecules where the application of the exciton model yields ambiguous conclusions. The use of 2,2′‐diphenyl‐[3,3′‐biphenanthrene]‐4,4′‐diol, known as VAPOL, as a chiral ligand for enantioselective catalysis necessitates the reliable determination of its absolute configuration. Based on the X‐ray diffraction data of its phosphoric amide derivative, the configuration of VAPOL has been determined in the literature to be (+)‐(aS). The experimental vibrational circular dichroism, ECD and optical rotatory dispersion spectra, and corresponding quantum mechanical predictions of VAPOL are used in this manuscript to independently determine its absolute configuration.

Entropy production in chiral symmetry breaking transitions
Authors: Kondepudi Dilip , Kapcha Lauren 
Published: October 2007

AbstractIt is now well known that nonequilibrium chemical systems may reach conditions that spontaneously generate chiral asymmetry. One can find a host of model reactions that exhibit such behavior in the literature. Among these, models based on one originally devised by Frank have been studied extensively. Though the kinetic aspects of such model reactions have been discussed in great detail, the behavior of entropy in such systems is rarely discussed. In this article, the rate of entropy production per unit volume, σ, in a modified Frank model is discussed. It is shown that the slope of σ changes at the point at which the asymmetric states appear, behavior similar to that observed in second‐order phase transitions.

Structural and Relaxometric Characterization of Peptide Aggregates Containing Gadolinium Complexes as Potential Selective Contrast Agents in MRI
Authors: Vaccaro Mauro , Mangiapia Gaetano , Paduano Luigi , Gianolio Eliana , Accardo Antonella , Tesauro Diego , Morelli Giancarlo 
Published: October 2007

AbstractThe structural and relaxometric characterization of a novel class of supramolecular aggregates, as potential tumor‐specific contrast agents in magnetic resonance imaging (MRI), is reported. The aggregates are based on a new monomer with an upsilon shape (MonY) that contains, in the same molecule, all three fundamental tasks that are required: 1) a hydrophobic moiety that allows the formation of supramolecular aggregates; 2) the bioactive CCK8 peptide for target recognition; and 3) a chelating agent able to give stable gadolinium complexes. As indicated by dynamic light scattering and small‐angle neutron scattering (SANS) measurements, MonY and its gadolinium complex MonY(Gd) aggregate in aqueous solution to give ellipsoidal micelles with a ratio between the micellar axes of ≈1.7 and an aggregation number Nagg of ≈30. There are no differences in the aggregation behavior of MonY and MonY(Gd), which indicates that the presence of metal ions, and therefore the reduction of the net charge, does not influence the aggregation behavior. When MonY or MonY(Gd) are blended with dioleoyl phosphatidylcholine (DOPC), the aggregation behavior is dictated by the tendency of DOPC to give liposomes. Only when the amount of MonY or MonY(Gd) is higher than 20 % is the coexistence of liposomes and micelles observed. The thickness d of the bilayer is estimated by SANS to be ≈35–40 Å, whereas cryogenic transmission electron microscopy images show that the diameter of the liposomes ranges from ≈50 to 150 nm. Self‐assembling micelles of MonY(Gd) present high relaxivity values (r1p=15.03 mM−1 s−1) for each gadolinium complex in the aggregate. Liposomes containing MonY(Gd) inserted in the DOPC bilayer at a molar ratio of 20:80 present slightly lower relaxivity values (r1p=12.7 mM−1 s−1), independently of their internal or external position in the liposome.
Immunization with heat‐killed Francisella tularensis LVS elicits protective antibody‐mediated immunity

AbstractFrancisella tularensis (FT) has been classified by the CDC as a category A pathogen because of its high virulence and the high mortality rate associated with infection via the aerosol route. Because there is no licensed vaccine available for FT, development of prophylactic and therapeutic regimens for the prevention/treatment of infection is a high priority. In this report, heat‐killed FT live vaccine strain (HKLVS) was employed as a vaccine immunogen, either alone or in combination with an adjuvant, and was found to elicit protective immunity against high‐dose FT live vaccine strain (FTLVS) challenge. FT‐specific antibodies produced in response to immunization with HKLVS alone were subsequently found to completely protect naive mice against high‐dose FT challenge in both infection‐interference and passive immunization experiments. Additional passive immunization trials employing serum collected from mice immunized with a heat‐killed preparation of an O‐antigen‐deficient transposon mutant of FTLVS (HKLVS‐OAgneg) yielded similar results. These findings demonstrated that FT‐specific antibodies alone can confer immunity against high‐dose FTLVS challenge, and they reveal that antibody‐mediated protection is not dependent upon production of LPS‐specific antibodies.

AbstractObjectiveTo investigate body image disturbance in young women with and without an eating disorder (ED) across two different ethnic groups in Australia and Singapore.MethodThe relationship of body image disturbance to cultural orientation and socio‐cultural factors was analysed in 154 women with and without an ED. Participants were from the following backgrounds: North European Australian, East Asian Australian, Singaporean Chinese (SC) and North European expatriates in Singapore.ResultsIrrespective of cultural group, women with an ED had similar body dissatisfaction. Among those without an ED, SC women reported greater body dissatisfaction than all other cultural groups. Finally, within each cultural group, ED participants reported significantly higher body dissatisfaction than their non‐ED counterparts with the exception of SC women where there was no difference.DiscussionSocio‐cultural factors other than body image may play more important roles in SC women's ED psychopathology.

Prevalence and sociodemographic correlates of eating disorder endorsements among adolescents and young adults from China
Authors: Chen Hong , Jackson Todd 
Published: October 2007

AbstractThis research assessed the prevalence and sociodemographic correlates of eating disorder symptoms among young people from China. A sample of 1320 females and 783 males between 12 and 22 years of age was recruited from academic settings in various regions of China and completed a back‐translated Chinese version of the Eating Disorder Diagnostic Scale, as well as measures of body dissatisfaction and demographics. As expected, reported eating disorder symptoms and body dissatisfaction were significantly higher for females than males. Eating disorder symptoms and body dissatisfaction were also more pronounced for participants from higher income households. Finally, age differences in symptoms and body dissatisfaction were inconsistent. In sum, findings extend past prevalence research and highlight specific sociodemographic correlates of eating pathology and body dissatisfaction among Chinese adolescents and young adults.

A hybrid Lagrangian–Eulerian particle‐level set method for numerical simulations of two‐fluid turbulent flows
Authors: Li Zhaorui , Jaberi Farhad A. , Shih Tom I‐P. 
Published: October 2007

AbstractA coupled Lagrangian interface‐tracking and Eulerian level set (LS) method is developed and implemented for numerical simulations of two‐fluid flows. In this method, the interface is identified based on the locations of notional particles and the geometrical information concerning the interface and fluid properties, such as density and viscosity, are obtained from the LS function. The LS function maintains a signed distance function without an auxiliary equation via the particle‐based Lagrangian re‐initialization technique. To assess the new hybrid method, numerical simulations of several ‘standard interface‐moving’ problems and two‐fluid laminar and turbulent flows are conducted. The numerical results are evaluated by monitoring the mass conservation, the turbulence energy spectral density function and the consistency between Eulerian and Lagrangian components. The results of our analysis indicate that the hybrid particle‐level set method can handle interfaces with complex shape change, and can accurately predict the interface values without any significant (unphysical) mass loss or gain, even in a turbulent flow. The results obtained for isotropic turbulence by the new particle‐level set method are validated by comparison with those obtained by the ‘zero Mach number’, variable‐density method. For the cases with small thermal/mass diffusivity, both methods are found to generate similar results. Analysis of the vorticity and energy equations indicates that the destabilization effect of turbulence and the stability effect of surface tension on the interface motion are strongly dependent on the density and viscosity ratios of the fluids.

RCM‐TVD hybrid scheme for hyperbolic conservation laws
Authors: Zahran Yousef Hashem 
Published: October 2007

AbstractWe describe a hybrid method for the solution of hyperbolic conservation laws. A third‐order total variation diminishing (TVD) finite difference scheme is conjugated with a random choice method (RCM) in a grid‐based adaptive way. An efficient multi‐resolution technique is used to detect the high gradient regions of the numerical solution in order to capture the shock with RCM while the smooth regions are computed with the more efficient TVD scheme. The hybrid scheme captures correctly the discontinuities of the solution and saves CPU time. Numerical experiments with one‐ and two‐dimensional problems are presented.

The impact of news use and social capital on youth wellbeing: An aggregate‐level analysis
Authors: Beaudoin Christopher E. 
Published: October 2007

AbstractThe current study explores the socioenvironmental determinants of youth development, with a focus on the mass media and social capital; it tests a model in which news use and social capital influence youth wellbeing. Social capital is operationally defined in terms of youth involvement and perceptions of place, and youth wellbeing is measured with youth arrest and youth pregnancy. Individual‐level data come from three telephone surveys of adults in 38 counties in the state of Iowa, with macro‐level data coming from the same counties. Over time, youth involvement increased significantly, while youth pregnancy decreased significantly. Perceptions of place and youth arrest remained constant. After transforming the individual‐level measures to the aggregate, structural equation modeling offered support for a three‐step model in which news use influences social capital, which, in turn, influences youth wellbeing. © 2007 Wiley Periodicals, Inc.

Ranking institutional settings based on publications in community psychology journals
Authors: Jason Leonard A. , Pokorny Steven B. , Patka Mazna , Adams Monica , Morello Taylor 
Published: October 2007

AbstractTwo primary outlets for community psychology research, the American Journal of Community Psychology and the Journal of Community Psychology, were assessed to rank institutions based on publication frequency and scientific influence of publications over a 32‐year period. Three specific periods were assessed (1973–1983, 1984–1994, 1995–2004). Findings indicate that there were a large group of institutions that published articles during these periods. Those academic institutions that had the most published articles as well as the largest influence, based on citations by other authors, were identified. Using archival data from the community psychology literature represents one approach for identifying those settings that made substantial contributions to the development and growth of the field. © 2007 Wiley Periodicals, Inc.

Authors: Krishna Ravula Phani , Sistla Sarath Chandra , Smile Robinson , Krishnan R. 
Published: October 2007

AbstractPurposeTo assess the diagnostic value of gray‐scale sonography in differentiating benign reactive nodes from metastatic nodes in the groin.MethodsTwenty‐seven patients with carcinoma of the penis, 3 patients with cutaneous melanoma, and 2 patients with squamous cell carcinoma of the lower extremity with inguinal lymphadenopathy were studied. A total of 122 nodes in the groin were examined sonographically using a 7.5‐MHz probe. Sonographic features studied included lymph node size, longitudinal/transverse diameter (L/T) ratio, presence or absence of echogenic hilum, and appearance of the cortex. Pathologic confirmation was obtained via lymph node biopsy in 14 patients and groin dissection in 18 patients. Sonographic features were correlated with final pathology.ResultsForty‐four of 122 nodes were metastatic and 78 were benign. L/T <2 had a sensitivity of 81% in the diagnosis of metastasis. Absent hilum had a sensitivity of only 68% but a specificity of 95%. An eccentric cortex was also highly specific for malignancy (96%). Presence of any sonographic feature suggestive of metastasis has a high sensitivity (95%) and negative predictive value (96%). The combination of L/T ratio <2 and absent hilum had the highest specificity (97%) combined with a high positive predictive value (93%).ConclusionSonography is useful in the evaluation of groin nodes for metastatic disease. It can help select a suspicious lymph node for cytologic/histologic confirmation. © 2007 Wiley Periodicals, Inc. J Clin Ultrasound, 2008
Tooth replacement pattern of Coloborhynchus robustus (pterosauria) from the Lower Cretaceous of Brazil
Authors: Fastnacht Michael 
Published: October 2007

AbstractThe well preserved anterior upper and lower jaw fragment of an adult specimen of Coloborhynchus robustus (Pterosauria: Ornithocheiridae), SMNK 2302 PAL, allowed investigations of the replacement pattern of the dentition macroscopically and by using CT scans. The quantification of the dentition by Zahnreihen, Z‐Spacing, and replacement waves indicates a complex pattern of different replacement stages in which large gaps within the dentition were avoided. The specialized prey‐catching apparatus of Coloborhynchus thus could retain its function even following tooth replacement. The replacement process in the specimen took about 2/3 of the total life‐time of a tooth, and damaged teeth in the anterior jaw region may have been replaced more rapidly than posterior teeth. The distolingual replacement of the functional teeth delayed the time of their shedding in comparison with the circular resorption present in crocodiles. In contrast to these, the distolingual position of the replacement tooth did not decrease the biomechanical stability of the functional tooth, which can also be observed as a convergence in other thecodont dentitions, e.g., recent carnivore mammals. Teeth were shed when their replacement had reached about 60% of the full‐grown height. A comparison of the observed pattern is constricted by the preservation and preparation of other specimens. Unfortunately, no known specimen in public collections reaches the quality of Coloborhynchus robustus, SMNK 2302 PAL, so that comparable patterns in other specimens are not likely to be detected. J.

Novel lipoxygenase inhibitors as neuroprotective reagents
Authors: van Leyen Klaus , Arai Ken , Jin Guang , Kenyon Victor , Gerstner Bettina , Rosenberg Paul A. , Holman Theodore R. , Lo Eng H. 
Published: October 2007

AbstractThe lipid‐metabolizing enzyme 12/15‐lipoxygenase (12/15‐LOX) mediates cell death resulting from oxidative stress in both neurons and oligodendrocytes. Specifically, it may contribute to the pathophysiology of stroke and Alzheimer's and Parkinson's diseases. We report here that two of three specific 12/15‐LOX inhibitors, derived from a virtual screen by computer modeling and validated by inhibition of recombinant human 15‐LOX in vitro, are able to rescue both neuronal as well as oligodendroglial cells from cell death induced by oxidative stress. Thus, in a fairly streamlined process, an initial virtual screen of 50,000 compounds in a library of drug‐like molecules has led to the identification of two novel drug candidates for targeting LOX. Future studies of these novel neuroprotective inhibitors of 12/15‐LOX may provide new therapeutic opportunities to combat stroke and other neurodegenerative diseases. © 2007 Wiley‐Liss, Inc.
The influence of work‐family culture and workplace relationships on work interference with family: a multilevel model
Authors: Major Debra A. , Fletcher Thomas D. , Davis Donald D. , Germano Lisa M. 
Published: October 2007

AbstractThis research tested a multilevel model examining the influence of work‐family culture and supportive workplace relationships on work interference with family. Web‐based survey data were provided by 792 information technology employees from 10 organizations. Random coefficient modeling was used to test a path model examining the relationships between work‐family culture, leader‐member exchange (LMX), coworker support, and work interference with family. The direct effects of LMX and coworker support on work interference with family were significant. The indirect effect of work‐family culture on work interference with family was also significant. Results demonstrate the value of work‐family culture in understanding supportive supervisory and coworker relationships and work interference with family and highlight the need to employ multilevel models to understand these relationships.
