Abstract
In 2004 to 2006, in the Okanagan Valley, British Columbia, Canada, we measured pesticides, water chemistry, and hatching success of Great Basin spadefoot (Spea intermontana), Pacific treefrog (Pseudacris regilla), Western toad (Bufo boreas), and Columbia spotted frog (Rana luteiventris). Predator-proof cages containing Gosner Stage 4 eggs were placed in ponds in nonagricultural reference sites in conventionally sprayed and organic orchards. Seventeen pesticides were detected in ponds in sprayed orchards but occurred at low concentrations (ng/L) except for diazinon (1,410 ng/L). Chloride, sulfate, conductivity, nitrate, and phosphorus showed significant differences among sites. Spadefoot mean hatching success ranged from 0 to 92% among sprayed orchards, whereas the range was 48 to 98.6% among organic orchards and 51 to 95.5% among reference sites. Mean hatching success for Pacific treefrog was 22.1 to 76.1% among sprayed orchards, whereas the range was 83.4 to 97.1% among reference sites. Although sample sizes were small and replication was low, we found that trends in hatching success of eggs of Western toad and Columbia spotted frogs were consistent with the other species. Variables that correlated negatively with amphibian hatching success included 12 pesticides and seven water chemistry parameters. However, stepwise regression found that, in 2005, atrazine accounted for 79% of the variation in spadefoot hatching success and, in 2006, atrazine, total nitrate, and chlorpyrifos accounted for 80%. For Pacific treefrog there were no significant correlations with pesticide concentrations; rather, hatching success correlated with water chemistry parameters. The present study also emphasizes the variability in species sensitivity and importance of incorporating water chemistry into the interpretation of water quality for amphibians. Environ. Toxicol.

Abstract
We conducted dose–response exposures to compare the lethality of endosulfan, diazinon, and azinphosmethyl in the early-life stages of the Great Basin spadefoot (Spea intermontana) and the Pacific treefrog (Pseudacris regilla). Our experiment occurred in two 8-d phases: one, with developing embryos, and two, with Gosner Stage 27 tadpoles. Pesticide concentrations were representative of field-measured concentrations (60 ng/L of endosulfan, 50 ng/L of azinphosmethyl, and 350 ng/L of diazinon), in the same geographic areas where these species occur in British Columbia. Although the concentrations met the requirements for federal water quality guidelines, we observed mortalities, deformities, and other sublethal effects. Phase 1 consisted of exposing Gosner Stage 10 embryos in the pesticide solutions for a total of 8 d. Significant mortality of S. intermontana began posthatch in the highest lethal concentrations of the commercial formulations of endosulfan (Thiodan; LC208d = 2,672.7 ng/L) and diazinon (LC208d &gt;175,000 ng/L). Phase 2 compared behavior, morphology, and survival of captive-reared tadpoles exposed to the same 8-d experimental regime as the embryo experiment. Endosulfan induced significant effects on behavior and morphology of P. regilla and significantly reduced survivorship of S. intermontana (LC208d = 77.1 ng/L). Abnormal behavior and excitability was observed in both species, with P. regilla tadpoles being more sensitive. At 60,000 ng/L endosulfan, P. regilla also lost pigmentation and exhibited abnormal tail morphology. Environ. Toxicol. Chem. 2010;29:1604–1612. © 2010 SETAC
A novel implicit numerical treatment for non‐linear turbulence models using high and low Reynolds number formulations
Authors: Assato Marcelo , de Lemos Marcelo J. S. 
Published: April 2010

AbstractNon‐linear turbulence models can be seen as an improvement of the classical eddy‐viscosity concept due to their better capacity to simulate characteristics of important flows. However, application of non‐linear models demand robustness of the numerical method applied, requiring a stable discretization scheme for convergence of all variables involved. Usually, non‐linear terms are handled in an explicit manner leading to possible numerical instabilities. Thus, the present work shows the steps taken to adapt a general non‐linear constitutive equation using a new semi‐implicit numerical treatment for the non‐linear diffusion terms. The objective is to increase the degree of implicitness of the solution algorithm to enhance convergence characteristics. Flow over a backward‐facing step was computed using the control volume method applied to a boundary‐fitted coordinate system. The SIMPLE algorithm was used to relax the algebraic equations. Classical wall function and a low Reynolds number model were employed to describe the flow near the wall. The results showed that for certain combination of relaxation parameters, the semi‐implicit treatment proposed here was the sole successful treatment in order to achieve solution convergence. Also, application of the implicit method described here shows that the stability of the solution either increases (high Reynolds with non‐orthogonal mesh) or preserves the same (low Reynolds number applications). Additional advantages of the procedure proposed here lie in the possibility of testing different non‐linear expressions if one considers the enhanced robustness and stability obtained for the entire numerical algorithm.

Published: April 2010

AbstractIf endothelial progenitor cells (EPCs), which circulate in blood flow, are captured on the luminal surface of an implanted artificial graft and sooner or later proliferate to form a fully endothelialized surface, such a small‐diameter artificial graft must exhibit a high patency rate. This study aimed at designing a luminal surface of elastomeric electrospun mesh graft, which is capable of selective capture of EPCs under arterial flow and has a high antithrombogenic potential until full endothelization is achieved. The designed luminal surface layer is composed of a photopolymerized gelatin gel layer that enables the release of impregnated heparin and selective adhesion of circulating EPCs via complexation between surface‐fixed vascular endothelial growth factor (VEGF) and cellular VEGF receptor. Human mononuclear cells seeded and cultured on such a gel layer expressed endothelial cell surface markers. Confocal laser scanning microscopy observation revealed that VEGF is highly surface‐enriched, and heparin is homogeneously distributed in the gel layer. A continuously slow release of heparin was observed. Thus, a prototype luminal surface was fabricated on electrospun segmented polyurethane tubes for in vivo study. © 2010 Wiley Periodicals, Inc.

Published: April 2010

AbstractSynthetic calcium‐deficient apatites (CDA) are structurally similar to biological apatites and are well known as chemical precursors of biphasic calcium phosphates (BCP). BCP are mixtures of hydroxyapatite and β‐tricalcium phosphate and are widely used as bone substitutes in human surgery. Bupivacaine, a local anesthetic, has been loaded onto CDA using isostatic compaction. The purpose of this study was to evaluate the in vivo performance of such a local release on pain after having previously defined the in vitro release profile of bupivacaine. CDA was loaded with 1%, 4%, and 16% of bupivacaine using an isostatic compaction process. In vitro release profile assays performed indicated the complete release of bupivacaine after 24 h. Wistar male rats received 50 mg implants of CDA associated, respectively, with 0, 1%, 4%, and 16% of bupivacaine into the distal femur. Analgesia was measured using the electronic version of the Von Frey monofilament test, assessing the inflammatory response and a neurological score. During the first postoperative days, a dose‐dependent analgesic effect was observed with the bupivacaine adsorbed on the resorbable implant. This combined device system thus appears to release local anesthetic in a manner that prevents or limits postoperative pain following bone surgery. This innovative approach could be integrated into a global pain management program, for example, in the context of bone harvesting where bone reconstruction is required. © 2010 Wiley Periodicals, Inc.

AbstractThis study evaluated the effect of resin monomer composition on crystal growth at the interface between the resin/bioglass composites and water. Light‐cured resin that contained 2‐bis[4(2‐hydroxy‐3‐methacryloyloxy‐propyloxy)‐phenyl], 2‐hydroxyethyl methacrylate, and triethylene glycol dimethacrylate with different compositions were used. Resin/bioglass composites were prepared with 40 mass% bioglass and 60 mass% resin. The resin/bioglass composites were stored in deionized distilled water for 24 h (control group) or 3–12 months (experimental groups). After water storage, the disk surfaces were examined by light‐ and scanning electron microscopy. Chemical states of the crystals were analyzed by laser‐Raman spectroscopy and micro‐X‐ray diffractometry. The microscopic analysis showed crystal on the resin disks surface after six months of water storage for hydrophilic resins. However, there was no crystal formation in the control and the experimental groups of specimens of hydrophobic resins. Raman analysis showed the chemical states of the crystals formed on the resin matrix and bioglass to be different. The micro‐X‐ray analysis of crystals on resin disks identified them to be calcium carbonate. This crystal formation occurred in water instead of simulated body fluid. In conclusion, the resin monomer compositions affected the ability to induce crystal growth on the surfaces of disks containing bioglass. © 2010 Wiley Periodicals, Inc.

The FRAX tool in French women: How well does it describe the real incidence of fracture in the OFELY cohort

Published: April 2010

Abstract
The FRAX tool estimates an individual's fracture probability over 10 years from clinical risk factors with or without bone mineral density (BMD) measurement. The aim of our study was to compare the predicted fracture probabilities and the observed incidence of fracture in French women during a 10-year follow-up. The probabilities of fracture at four major sites (hip, clinical spine, shoulder, or wrist) and at the hip were calculated with the FRAX tool in 867 women aged 40 years and over from the Os des Femmes de Lyon (OFELY) cohort.The incidence of fracture was observed over 10 years. Thus 82 women sustained 95 incident major osteoporotic (OP) fractures including 17 fractures at the hip. In women aged at least 65 years (n = 229), the 10-year predicted probabilities of fracture with BMD were 13% for major OP fractures and 5% for hip fractures, contrasting with 3.6% and 0.5% in women younger than 65 years (p &lt; .0001). The predicted probabilities of both major OP and hip fractures were significantly higher in women with osteoporosis (n = 77, 18% and 10%) and osteopenia (n= 390, 6% and 2%) compared with women with normal BMD (n = 208, 3% and &lt;1%; p &lt; .0001. The predicted probabilities of fracture were two and five times higher in women who sustained an incident major OP fracture and a hip fracture compared with women who did not (p &lt; .0001). Nevertheless, among women aged at least 65 years with low BMD values (T-score ≤ –1; n = 199), the 10-year predicted probability of major OP fracture with BMD was 48% lower than the observed incidence of fractures (p &lt; .01). A 10-year probability of major OP fracture higher than 12% identified more women with incident fractures than did BMD in the osteoporotic range (p &lt; .05). In French women from the OFELY cohort, the observed incidence of fragility fractures over 10 years increased with age following a pattern similar to the predicted probabilities given by the FRAX tool. However, in women aged at least 65 years with low BMD, the observed incidence of fractures was substantially higher than the predicted probability. © 2010 American Society for Bone and Mineral Research.
Effects on bone geometry, density, and microarchitecture in the distal radius but not the tibia in women with primary hyperparathyroidism: A case-control study using HR-pQCT
Authors: Hansen Stinus , Beck Jensen Jens-Erik , Rasmussen Lars , Hauge Ellen M , Brixen Kim 
Published: April 2010

Abstract
Patients with primary hyperparathyroidism (PHPT) have continuously elevated parathyroid hormone (PTH) and consequently increased bone turnover with negative effects on cortical (Ct) bone with preservation of trabecular (Tb) bone. High-resolution peripheral quantitative computed tomography (HR-pQCT) is a new technique for in vivo assessment of geometry, volumetric density, and microarchitecture at the radius and tibia. In this study we aimed to evaluate bone status in women with PHPT compared with controls using HR-pQCT. The distal radius and tibia of 54 women—27 patients with PHPT (median age 60, range 44–75 years) and 27 randomly recruited age-matched healthy controls (median age 60, range 44–76 years)—were imaged using HR-pQCT along with areal bone mineral density (aBMD) by dual-energy X-ray absorptiomentry (DXA) of the ultradistal forearm, femoral neck, and spine (L1–L4). Groups were comparable regarding age, height, and weight. In the radius, patients had reduced Ct area (Ct.Ar) (p = .008), Ct thickness (Ct.th) (p = .01) along with reduced total (p = .002), Ct (p = .02), and Tb (p = .02) volumetric density and reduced Tb number (Tb.N) (p = .04) and increased Tb spacing (Tb.sp) (p = .05). Ct porosity did not differ. In the tibia, no differences in HR-pQCT parameters were found. Moreover, patients had lower ultradistal forearm (p = .005), spine (p = .04), and femoral neck (p = 0.04) aBMD compared with controls. In conclusion, a negative bone effect of continuously elevated PTH with alteration of HR-pQCT assessed geometry, volumetric density, and both trabecular and cortical microarchitecture in radius but not tibia was found along with reduced aBMD by DXA at all sites in female patients with PHPT. © 2010 American Society for Bone and Mineral Research
Gender differences in risk/protection profiles for low academic performance
Authors: Whitney Stephen D. , Renner Lynette M. , Herrenkohl Todd I. 
Published: April 2010

AbstractUsing holistic‐interactionistic theory, the simultaneous nature of risk and protection factors for both males and females (age 6–11 in Wave 1) is examined using latent profile analysis (LPA). Risk/protection classes are estimated using multiple risk factor variables (e.g., physical child abuse) and multiple protective factors (e.g., extracurricular activities). These risk/protection classes were used to predict low academic performance. For both males and females, high risk, low protection individuals were significantly more likely to experience low academic performance than low risk, high protection cases. Gender differences emerged in a class for females that included the importance of parental/peer disapproval of antisocial behavior as a protective factor that was not present for males. Findings support elements of the holistic‐interactionistic theory for human development and suggest the need to examine risk and protective factors in combination to account for their shared influences on developmental outcomes. Implications for youths underperforming academically are discussed. © 2010 Wiley Periodicals, Inc.
Race, neighborhood disadvantage, and antisocial behavior among female juvenile offenders

Published: April 2010

AbstractThe current study evaluated the significance of two theoretical positions, differential involvement and differential selection, that may lead to disproportionate minority contact among female juvenile offenders. Using a longitudinal, multimethod research design, reoffending was assessed prospectively using self‐report data and official records of offending; neighborhood disadvantage was assessed using census level data. Results supported the differential selection hypothesis and found that Black girls were significantly more likely to get rearrested, particularly for nonviolent crimes, but both Black and White girls self‐reported similar levels of antisocial behavior. After accounting for neighborhood disadvantage, race was not significantly associated with nonviolent rearrest. The results highlight the important role of neighborhoods in explaining the discrepant representation of Black girls within the juvenile and criminal justice systems. They further suggest that neighborhoods might be a key conduit by which minorities are differentially “selected” into the justice system. © 2010 Wiley Periodicals, Inc.
Assessing the use of cutinase reversed micellar catalytic system for the production of biodiesel from triglycerides
Authors: Badenes Sara M. , Lemos Francisco , Cabral Joaquim M. S. 
Published: April 2010

AbstractBACKGROUND: This work evaluates the use of a reversed micellar catalytic system containing a lipolytic biocatalyst, cutinase, to promote the reaction of triglycerides with methanol, ethanol or butanol for the production of biodiesel in isooctane.RESULTS: The specific activity of cutinase increased with increase of the alcohol chain length, and methanol showed a significant toxicity toward the enzyme leading to a specific activity decrease for high concentrations of this alcohol, which did not occur when ethanol or butanol were used. The composition of the mixture was analyzed and it was shown that, although the reaction could proceed without water, the presence of water allowed higher reaction rates and higher conversions, probably because water helps to maintain both the micellar structure and lipase conformation. Excess water, however, had a deleterious effect on conversion.CONCLUSION: The influence of water and methanol, apart from micelle structure, was found to be linked to partition effects of diglyceride and monoglyceride, which may also have a significant impact on the reaction rate.

A changing scene: Comparing business cultures in Peru and the Netherlands
Authors: Torres Daniel More , Jones Stephanie 
Published: April 2010

AbstractThe objective of this study was initially to examine the differences in the business cultures of Peru and the Netherlands; in the process, it was discovered that the traditional view of the culture of Peru, as described in the cross‐cultural management literature, would appear to have lost some accuracy and relevance over the last 20–30 years. Peruvian businesspeople, quantitatively compared in matched pairs with Dutch counterparts, show cultural behavioral preferences at odds with the profile recorded by Hofstede. Meanwhile the Dutch sample, although showing some cultural evolution in the last few decades, reveals less dramatic culture change. To identify the cultural differences, a range of businesspeople in Peru and the Netherlands was surveyed. An overall total of 76 matched pairs (two individuals who were alike in terms of age, gender, years of education, and whether they were entrepreneurs, differing only in being Peruvian or Dutch) were questioned. It was concluded that, although based on a much smaller sample, these findings may shed doubt upon traditionally accepted profiles of other South American countries and, indeed, on other countries that may have undergone significant economic, social, and political change over recent decades. © 2010 Wiley Periodicals, Inc.
