Published: August 2011

AbstractBACKGROUND: The health benefits of n‐3 fatty acids have led to much research on manipulating the fatty acid composition of animal‐derived foods. In this study, two experiments were conducted to investigate the interaction of dietary fatty acids on egg yolk fatty acid concentrations. In experiment I, 32 dietary treatments with three replicates of three birds each were fed for 35 days. Diets were prepared by mixing one type of fish oil with four vegetable oils in different proportions. In experiment II, three different types and two levels of fish oil in combination with two vegetable oils were tested under the same conditions as in experiment I.RESULTS: In experiment I the results showed that the egg yolk saturated (SFA) and monounsaturated (MUFA) fatty acid concentration was determined by the dietary SFA, MUFA and 18:2n‐6 content. The egg 18:2n‐6 concentration was mainly explained by the dietary inclusion of 18:2n‐6 and negatively by the dietary MUFA content. The egg C18:3n‐3, C20:5n‐3 and C22:6n‐3 concentration is almost exclusively determined by their direct supply from the diet. The egg 20:4n‐6 concentration was inversely proportional to the long‐chain n‐3 polyunsaturated fatty acid content of the diet. The results of experiment II showed that the egg yolk C20:5n‐3 and C22:6n‐3 concentration was determined by both the level of dietary fish oil (1 or 2%) and the C20:5n‐3/C22:6n‐3 ratio in the fish oil.CONCLUSION: The results of this study demonstrated that the direct dietary supply of fatty acids is the most important factor determining the egg yolk fatty acid composition, in particular for the n‐3 fatty acids. The interaction effect from other dietary fatty acids was in general small. Copyright © 2011 Society of Chemical Industry

AbstractSurgically implanted satellite transmitters have been widely used in studies of avian ecology, yet little is known about their potential impacts on birds. We implanted satellite transmitters with percutaneous antennae (approx. 50 g) in 17 female common eiders (Somateria mollissima) at a breeding colony in Arctic Canada. Among females implanted during incubation, 11 of 12 nests were abandoned within 1 week of being radioed. We observed no differences in the proportion of time that implanted female eiders allocated to basic behaviors. Radioed birds were more likely to pick or preen their abdominal (site of surgical incision) and posterior–dorsal (site of antenna exit) regions than unmarked females, although these behaviors were rare (approx. 0.3% of total time budget). Three of 10 females re‐observed had a pronounced limp following surgery, but we observed no walking difficulties among these females in subsequent seasons, and we observed some implanted eiders nesting in subsequent years. Mark–resighting models suggest eiders with transmitters had lower apparent survival the year after implantation (67.0%; 85% CI: 47.8–81.9%) than did color‐banded eiders (87.5%, 85% CI: 82.5–91.2%), but there was no model support for a survival difference in subsequent years. We conclude that transmitter implantation in common eiders leads to short‐term changes in behavior and a decline in first year survival. We encourage researchers to collect similar data on their study subjects where possible and use it to determine the degree to which data are representative of the greater population. © 2011 The Wildlife Society.
Self‐Assembled Antimicrobial and Biocompatible Copolymer Films on Titanium

Published: August 2011

AbstractCopolymers of 4‐vinyl‐N‐hexylpyridinium bromide and dimethyl(2‐methacryloyloxyethyl) phosphonate self‐assemble to form ultrathin layers on titanium surfaces that show antimicrobial activity, and biocompatibility. The copolymer layers are characterized by contact angle measurements, ellipsometry and XPS. Antibacterial activity is assessed by investigation of adherence of S. mutans. Biocompatibility is rated based on human gingival fibroblast adhesion and proliferation. By balancing the opposing effects of the chemical composition on biocompatibility and antimicrobial activity, copolymer coatings are fabricated that are able to inhibit the growth of S. mutans on the surface but still show attachment of gingival fibroblasts, and therefore might prevent biofilm formation on implants. magnified image

AbstractObjectiveTo evaluate postoperative satisfaction, including improvements in quality of life, among patients who had undergone labia minora reduction.MethodsIn a retrospective descriptive study, women who had undergone labiaplasty for hypertrophy of the labia minora between January 2005 and December 2009 were contacted by telephone. The women were asked to answer a satisfaction survey evaluating the esthetic and functional results of the surgery.ResultsAmong 21 patients who had labiaplasty using either a pedicle flap reconstruction (n = 18, 86%) or a nymphectomy technique (n = 3, 14%), 18 (86%) were contacted successfully and took part in the survey. All of the contacted patients were satisfied with the overall outcome of the surgery, with a mean rating of 8.7 out of 10 at a median follow‐up of 17 months (interquartile range 6–25 months). From an esthetic point of view, all 18 patients reported an improvement in comfort with respect to any form of original functional discomfort. Concerning sexuality, 95% of the sexually active patients had originally described some form of physical or psychologic discomfort, and all of them reported total disappearance of this symptomatology.ConclusionLabiaplasty provided overall satisfaction in terms of improvements in patient quality of life and sexuality.

Authors: De Smet Els , Jaecques Siegfried V. N. , Wevers Martine , Sloten Jos Vander , Naert Ignace E. 
Published: August 2011

ABSTRACTBackground: Strain, frequency, loading time, and strain rate, among others, determine mechanical parameters in osteogenic loading. We showed a significant osteogenic effect on bone mass (BM) by daily peri‐implant loading at 1.600 µε.s−1 after 4 weeks.Purpose: To study the peri‐implant osteogenic effect of frequency and strain in the guinea pig tibia by in vivo longitudinal micro‐computed tomography (CT) analysis.Material and Methods: One week after implant installation in both hind limb tibiae, one implant was loaded daily for 10′ during 4 weeks, while the other served as control. Frequencies (3, 10, and 30 Hz) and strains varied alike in the three series to keep the strain rate constant at 1.600 µε.s−1. In vivo micro‐CT scans were taken of both tibiae: 1 week after implantation but before loading (v1) and after 2 (v2) and 4 weeks (v3) of loading as well as postmortem (pm). BM (BM (%) bone‐occupied area fraction) was calculated as well as the difference between test and control sides (delta BM)Results: All implants (n = 78) were clinically stable at 4 weeks. Significant increase in BM was measured between v1 and v2 (p < .0001) and between v1 and v3 (p < .0001). A significant positive effect of loading on delta BM was observed in the distal peri‐implant marrow 500 Region of Interest already 2 weeks after loading (p = .01) and was significantly larger (11%) in series 1 compared with series 2 (p = .006) and 3 (p = .016).Conclusions: Within the constraints of constant loading time and strain rate, the effect of early implant loading on the peri‐implant bone is strongly dependent on strain and frequency. This cortical bone model has shown to be most sensitive for high force loading at low frequency.
Analysis of Porphyromonas gingivalis PG27 by deletion and intragenic suppressor mutation analyses
Authors: Ishiguro I. , Saiki K. , Konishi K. 
Published: August 2011

SummaryPG27 is required for secretion of virulence factor gingipains, and has recently been proposed as LptO, which is involved in O‐deacylation of lipopolysaccharide. In the present study, a predicted 14 anti‐parallel β‐strand structure of PG27 was ascertained. Deletion study showed that the region from Asp382 to the C‐terminal His391 of PG27 is dispensable for the function of PG27. Analysis of C‐terminal deletion mutants revealed that the region in strand S14 (Asn369–Gly385) is important for activity. Of the gingipain‐defective mutants, ΔThr378–His391 and ΔPhe377–His391 produced amounts of PG27 comparable to those produced by wild‐type cells, suggesting that Thr378–Phe381 contains essential residues for the function of PG27. In contrast, ΔPhe381–His391, ΔAla380–His391, ΔLeu379–His391 and ΔArg376–His391 produced no detectable PG27. The defects of the ΔAla380–His391 mutant were suppressed by changing either Ala346 or Ala359 of PG27 to valine. Importantly, Ala346 and Ala359 are located close to Leu379 in the structural model of PG27. A359V compensated for the instability of PG27, but not the gingipain‐defective phenotypes, of other deletion mutants tested, suggesting that Ala380 and Phe381 of PG27 are important for the stability of PG27. Lastly, we found that the C‐terminal region of PG27 may be located in the periplasm. Taken together, these findings fit well with a predicted β‐barrel structure model for PG27, and show that strand S14 is important for its function.

AbstractPresented theoretical paper concerns the structure investigation of Si/SiGe/Si heterojunction bipolar device by the extremely sensitive Grazing-angle Incidence X-ray Backdiffraction (GIXB) technique. The silicon cap layer and the silicon substrate have the same value of the spacing period along the growth surface according the proposed model of heterostructure. However, a longitudinal space shift exists between their lattice space periods. Appearance of the space shift is stipulated by the interface misfit dislocations. The magnitude of the space shift is one of the important characteristics of crystalline layers and substrate interface quality, and can be used for the non-destructive control of device parameters during the growth and fabrication processes.
Symptomatic Hypocalcemia due to Sodium Phosphate for Bowel Preparation following Minimally Invasive Parathyroidectomy
Authors: Kirdak Turkay , Korun Nusret 
Published: August 2011

ABSTRACT
This paper presents a case on symptomatic hypocalcemia due to sodium phosphate use for bowel preparation following parathyroidectomy. Serum calcium and parathyroid hormone were in normal levels postoperatively. Two months following the operation, phosphosoda was administered for bowel preparation. Following bowel preparation severe carpopedal spasm developed. It can be speculated that sodium phosphate administration for bowel preparation may precipitate hypocalcemic tetany in the patients undergoing parathyroidectomy for primary hyperparathyroidism.

AbstractNatural killer (NK) cells are cytotoxic lymphocytes able to kill tumor cells and virus‐infected cells. Human‐resting NK cells can be activated by co‐culture with NK‐resistant CTV‐1a cells. These tumor‐activated cells (TaNKs) are cytotoxic to a range of NK‐resistant tumor cells in vitro. This potential, however, has not been explored in multiple myeloma (MM). In this study, we demonstrate that TaNK cells from 21 MM patients lyse a variety of myeloma targets, including primary isolates of autologous and allogeneic CD138+ myeloma cells whilst sparing CD138−ve bone marrow cells. Myeloma patients' TaNK‐induced lysis of the U266 cell line was significantly higher compared to normal controls (median‐specific lysis 79.1% vs. 69.5%) (P = 0.003). In addition, TaNKs induced substantial lysis of autologous and allogeneic CD138+ myeloma cells (median‐specific lysis 52.5% and 37.4%, respectively). The percentage of specific lysis did not correlate with important disease characteristics (ISS, age, and high‐risk molecular abnormalities) or with the disease status and antimyeloma treatment, including novel agents and dexamethasone. In conclusion, tumor‐primed NK cells are able to induce substantial lysis of myeloma targets including autologous and allogeneic CD138+ myeloma plasma cells and could be an additional therapeutic approach in MM, particularly in the era of novel agents.

AbstractA genetic predisposition for thoracic aortic aneurysms and dissections (TAAD) can be inherited in an autosomal dominant manner with decreased penetrance and variable expression. Four genes identified to date for familial TAAD account for approximately 20% of the heritable predisposition. In a cohort of 514 families with two or more members with presumed autosomal dominant TAAD, 48 (9.3%) families have one or more members who were at 50% risk to inherit the presumptive gene causing TAAD had an intracranial vascular event. In these families, gender is significantly associated with disease presentation (P < 0.001), with intracranial events being more common in women (65.4%) while TAAD events occurred more in men (64.2%,). Twenty‐nine of these families had intracranial aneurysms (ICA) that could not be designated as saccular or fusiform due to incomplete data. TGFBR1, TGFBR2, and ACTA2 mutations were found in 4 families with TAAD and predominantly fusiform ICAs. In 15 families, of which 14 tested negative for 3 known TAAD genes, 17 family members who were at risk for inheriting TAAD had saccular ICAs. In 2 families, women who harbored the genetic mutation causing TAAD had ICAs. In 2 additional families, intracranial, thoracic and abdominal aortic aneurysms were observed. This study documents the autosomal dominant inheritance of TAADs with saccular ICAs, a previously recognized association that has not been adequately characterized as heritable. In these families, routine cerebral and aortic imaging for at risk members could prevent cerebral hemorrhages and aortic dissections. © 2011 Wiley‐Liss, Inc.

AbstractBACKGROUND: Since cyclophosphamide is metabolically activated to teratogenic acrolein and cytotoxic phosphoramide mustard by cytochrome P‐450 type 2B (CYP2B), we assessed the effects of licorice, a CYP2B inducer, on the fetal defects induced by cyclophosphamide. METHODS: Pregnant Sprague‐Dawley rats were daily administered with licorice (100 mg/kg) by gavage for 7 days, from the 6th to 12th day of gestation, and intraperitoneally administered with cyclophosphamide (11 mg/kg) 1 hr after the final licorice treatment. On the 20th day of gestation, maternal and fetal abnormalities were determined by Cesarian section. RESULTS: Cyclophosphamide was found to reduce fetal and placental weights without increasing resorption or death. In addition, it induced malformations in live fetuses; 93.8, 41.1, and 100% of the external (skull and limb defects), visceral (cleft palate and ureteric dilatation), and skeletal (acrania, vertebral/costal malformations, and delayed ossification) abnormalities, respectively. When pre‐treated with licorice, cyclophosphamide‐induced body weight loss and abnormalities of fetuses were remarkably aggravated. Moreover, repeated treatment with licorice greatly increased mRNA expression and activity of hepatic CYP2B. CONCLUSIONS: The results indicate that repeated intake of licorice may aggravate cyclophosphamide‐induced body weight loss and malformations of fetuses by upregulating CYP2B.

Direct loss model for seismically damaged structures
Authors: Mander John B. , Sircar Jyotirmoy , Damnjanovic Ivan 
Published: August 2011

SUMMARYLoss ratio, which is the ratio of the repair cost to the total replacement cost, is an effective parameter for representing structural and nonstructural damage caused by earthquakes. A probabilistic loss estimation framework is first presented that directly relates hazard to response and hence to losses. A key feature of the loss estimation approach is the determination of losses without need for customary fragility curves. Relationships between intensity measures and engineering demand parameters are used to define the demand model. An empirically calibrated loss model in the form of a power curve with upper and lower cut‐offs is used in conjunction with the demand model to estimate loss ratios. Loss ratios for each of the damage states take into account epistemic uncertainty and an effect on price surge following a major hazardous event. The loss model is calibrated and validated for bridges designed based on the prevailing Caltrans, Japan, and New Zealand standards. The loss model is then transformed to provide a composite seismic hazard–loss relationship that is used to estimate the expected annual loss for structures. The closed‐form four‐step stochastic loss estimation model is applied to the bridges designed for ductility. Results of these ductile designs are compared to a bridge detailed to an emerging damage avoidance design philosophy. Copyright © 2011 John Wiley & Sons, Ltd.
Turbulence in a skewed three‐dimensional wall‐bounded shear flow: effect of mean vorticity on structure modification
Authors: Holstad A. , Andersson H. I. , Pettersen B. 
Published: August 2011

SUMMARYMean‐flow three‐dimensionalities affect both the turbulence level and the coherent flow structures in wall‐bounded shear flows. A tailor‐made flow configuration was designed to enable a thorough investigation of moderately and severely skewed channel flows. A unidirectional shear‐driven plane Couette flow was skewed by means of an imposed spanwise pressure gradient. Three different cases with 8°, 34°and 52°skewing were simulated numerically and the results compared with data from a purely two‐dimensional plane Couette flow. The resulting three‐dimensional flow field became statistically stationary and homogeneous in the streamwise and spanwise directions while the mean velocity vector V and the mean vorticity vector Ω remained parallel with the walls. Mean flow profiles were presented together with all components of the Reynolds stress tensor. The mean shear rate in the core region gradually increased with increasing skewing whereas the velocity fluctuations were enhanced in the spanwise direction and reduced in the streamwise direction.The Reynolds shear stress is known to be closely related to the coherent flow structures in the near‐wall region. The instantaneous and ensemble‐averaged flow structures were turned by the skewed mean flow. We demonstrated for the medium‐skewed case that the coherent structures should be examined in a coordinate system aligned with V to enable a sound interpretation of 3D effects. The conventional symmetry between Case 1 and Case 2 vortices was broken and Case 1 vortices turned out to be stronger than Case 2. This observation is in conflict with the common understanding on the basis of the spanwise (secondary) mean shear rate. A refined model was proposed to interpret the structure modifications in three‐dimensional wall‐flows. What matters is the orientation of the mean vorticity vector Ω relative to the vortex vorticity vector ωv, that is, the sign of Ω ·ωv. In the present situation, Ω ·ωv  >  0 for the Case 1 vortices causing a strengthening relative to the Case 2 vortices. Copyright © 2011 John Wiley & Sons, Ltd.
