Authors: Kováčik Jozef , Klejdus Bořivoj , Hedbavny Josef , Bačkor Martin 
Published: June 2009

AbstractTolerance of three Slovak populations of Silene vulgaris [from the localities “Harmanec” (total soil Cu 34.1 mg kg−1), “Lubietová”; (total soil Cu 831.6 mg kg−1) and “Špania dolina” (total soil Cu 1368.7 mg kg−1) referred as SV1, SV2, and SV3, respectively] and Silene dioica (SD; from the locality “Špania dolina”) exposed to 60 μM Cu for 7 days has been studied. Respective controls with 0.21 μM Cu were also cultured. SV3 and SD contained higher total shoot Cu than SV1. Methanol‐soluble shoot Cu represented 60, 59, 59, and 55% from total shoot Cu and roots contained 16.7‐, 20.4‐, 9.9‐ and 28.9‐fold more Cu than shoots in SV1, SV2, SV3, and SD, respectively. Soluble proteins were the least affected in SV3 and SD when Cu‐exposed and control plants were compared. Root hydrogen peroxide and superoxide showed similar trend and were correlated with enhancement of ascorbate‐ and guaiacol‐peroxidase activities. Malondialdehyde accumulation increased in SV1 and SV2. Phenylalanine ammonia‐lyase activity and total soluble phenols were higher in SV3 Cu‐exposed plants compared to SV1 and SV2. Shikimate dehydrogenase activity was enhanced in all Cu‐exposed populations. Cinnamyl alcohol dehydrogenase activity and root lignin content were not affected and polyphenol oxidase activity was not detected. Within 14 detected free amino acids, majority of them decreased preferentially in the roots. Only serine increased in shoots and decreased in roots of all populations. Potassium content was not affected in SV3. Na, Ca, and Fe increased in roots of Cu‐exposed plants of all populations, while Mg was the least affected and Zn increased in SV2 and SV3 shoots and roots. This study revealed the highest tolerance in population from the locality with the highest soil Cu content. Present findings as complex metabolic responses to Cu stress with special emphasis on phenolic metabolism are discussed. © 2009 Wiley Periodicals, Inc. Environ Toxicol 25: 581–592, 2010.
Toxicity of parathion on embryo and yolk‐sac larvae of gilthead seabream (Sparus aurata l.): Effects on survival, cholinesterase, and carboxylesterase activity

Published: June 2009

AbstractThis study was conducted to examine the acute toxicity of the organophosphorus pesticide (OP) parathion on embryos and yolk‐sac larvae of gilthead seabream (Sparus aurata), and to investigate the effects of this compound on cholinesterase and carboxylesterase activity of seabream larvae in the phase of endogenous feeding. The 72‐h LC50 for yolk‐sac larvae (0.523 mg L−1) was about two‐fold lower than the 48‐h LC50 for embryos (1.005 mg L−1). Parathion significantly inhibited the activity of ChE and CaE activity in yolk sac larvae but there were not significant differences in the sensitivity of both esterases to parathion as inferred by their 72‐h IC50 values. Larvae exposed to parathion for 72 h showed a 70% inhibition of the whole body acetylcholinesterase at approximately the LC50. © 2009 Wiley Periodicals, Inc. Environ Toxicol 25: 601–607, 2010.

Published: June 2009

AbstractObjectivesPreterm delivery is the leading cause of major perinatal morbidity and mortality associated with triplet pregnancies. The objective of this study was to evaluate the efficacy of ultrasound‐indicated cervical cerclage in triplet pregnancies that are diagnosed with cervical shortening on biweekly transvaginal sonography (TVS).MethodsA retrospective review of all triplets who were followed with biweekly TVS for measurement of cervical length was conducted. Cervical shortening was defined as cervical length ⩽ 2.5 cm. Outcomes of interest included cervical cerclage placement, gestational age at delivery and birth weight.ResultsIn our population of 24 triplet pregnancies, 13 had cervical shortening. Of these, 54% underwent cervical cerclage at a mean gestational age of 20 weeks. Overall, patients without cervical shortening delivered on average 17 days later than those with cervical shortening (32 + 2 weeks vs. 29 + 6 weeks, P = 0.034). Moreover, infants of patients without cervical shortening weighed on average 456 g more at birth than did those with cervical shortening (1751 g vs. 1295 g, P = 0.039) and had a lower percentage of very low birth weight infants (30.3% vs. 69.2%, P = 0.002). Within the subset of patients with cervical shortening, there was no statistical difference in any of the outcomes studied between patients who underwent cervical cerclage and those who did not.ConclusionsTriplet pregnancies complicated by cervical shortening diagnosed on biweekly TVS surveillance do not appear to benefit from placement of cervical cerclage, based on assessment of gestational age at delivery, birth weight and incidence of very low birth weight infants.

Cavum veli interpositi cyst: prenatal diagnosis and postnatal outcome
Authors: D'Addario V. , Pinto V. , Rossi A. C. , Pintucci A. , Di Cagno L. 
Published: June 2009

AbstractObjectiveThe cavum veli interpositi (CVI) is a space within the double‐layered tela choroidea of the third ventricle. Occasionally, this space is fluid‐filled and sonographically visible as an interhemispheric anechoic cyst. Because of its rarity, the incidence of CVI cyst is undetermined and the outcome of affected individuals has been found to be variable. The aim of this study was to report our experience of the sonographic findings and outcome of fetuses affected by CVI cysts.MethodsIn five fetuses with a CVI cyst, we performed targeted prenatal ultrasound scans of intracranial structures and a detailed anatomical survey to rule out associated malformations. Follow‐up consisted of neurological examination and neurosonography.ResultsThe CVI cyst appeared as a well‐defined anechoic lesion without adjacent mass effect. In all fetuses the cyst was single and in two cases it enlarged slightly during pregnancy. The cyst was isolated in three fetuses and associated with borderline ventriculomegaly in two. A single umbilical artery was the only associated extracranial anomaly and this was detected in only one fetus. Neurosonography confirmed the presence of CVI cysts in all cases after delivery. During postnatal follow‐up (range 10–48 months), the cyst regressed in one case within 1 month after delivery while the size of the others remained stable. No infant developed psychomotor disorders.ConclusionsPrenatal sonographic diagnosis of CVI cysts is feasible. Its finding in isolation is consistent with favorable postnatal outcome.

Published: June 2009

AbstractObjectivesTo investigate whether maternal history and ultrasound findings can be predictors for massive hemorrhage during Cesarean section in patients with placenta previa and adherence of the placenta.MethodsWe reviewed 127 singleton pregnancies with placenta previa. Maternal history, antenatal ultrasound findings of the placenta, including location, presence of placental lacunae, lack of a clear zone, presence of sponge‐like findings of the cervix and presence of a marginal sinus in cases of placenta previa were reviewed retrospectively, and their association with amount of bleeding during Cesarean section was analyzed.ResultsLogistic regression analysis revealed that advan‐ced maternal age (odds ratio (OR), 5.4; 95% CI, 1.8–16.4), previous Cesarean section (OR, 20.4; 95% CI, 4.0–105.2) and sponge‐like findings in the cervix (OR, 5.6; 95% CI, 1.8–17.0) were associated with massive bleeding (> 2500 mL). Placental adherence occurred in five cases and was more frequent in cases where the placenta was located at the site of the scar of a previous Cesarean section (OR, 123.1; 95% CI, 4.5–3395.2) and where there was lack of a clear zone (OR, 48.0; 95% CI, 3.8–604.7).ConclusionsAdvanced maternal age, previous Cesarean section and presence of sponge‐like findings in the cervix are risk factors for massive bleeding during Cesarean section in cases of placenta previa, regardless of whether placental adherence is present. Placental location on the scar of a previous Cesarean section and lack of a clear zone are risk factors for placental adherence. When these findings are identified preoperatively, management should be tailored accordingly. Copyright © 2009 ISUOG. Published by John Wiley & Sons, Ltd.

Published: June 2009

AbstractObjectiveThe congenital bony and musculoskeletal defect of the pelvis in bladder exstrophy–epispadias complex (BEEC) highly predisposes females to uterine prolapse. There is a paucity of knowledge on the anatomy of the pelvic soft tissue structures following surgery. The aim of this study was to investigate with transperineal three‐dimensional (3D) ultrasound the pubovisceral muscle in females with BEEC who had undergone surgical reconstruction in childhood.MethodsIn a cross‐sectional observational study we examined 12 Caucasian female BEEC patients, mean age 19.9 (range, 15.5–27.4) years, from a single center after a single‐stage functional reconstruction with closure of the anterior pelvic ring. As a control group we used 13 Caucasian nulligravidae. 3D transperineal ultrasound volumes were acquired with the patient at rest in the supine position and with an empty bladder, and established pelvic floor parameters were measured. Analysis was conducted offline by two independent investigators.ResultsNo statistical difference between the BEEC patients and the control group was observed in the anteroposterior diameter or the area of the levator hiatus, or in the maximal thickness of the levator muscle. However, significantly greater values were observed in BEEC patients in the transverse diameter of the levator hiatus (mean, 4.31 vs. 3.81 cm, P = 0.046) and in the levator angle (mean, 80.1 vs. 70.0°, P = 0.040). The measurements obtained in the control group were consistent with those previously reported in the literature.ConclusionsThis is the first study showing that transperineal 3D ultrasound can be used for the assessment of BEEC patients after functional reconstruction. Biometric pelvic floor parameters may be useful in the long‐term follow‐up of BEEC patients. Copyright © 2009 ISUOG. Published by John Wiley & Sons, Ltd.

Published: June 2009

AbstractThe paper presents research to develop a model complex that takes into account the interaction between the wind farm and the atmosphere, and between closely spaced wind farms. Six models have been reviewed and developed/adapted for use in wind farm modelling, covering scales from several hundred kilometres down to the size of the individual wind turbine. Flow within wind farms is difficult to predict. The analytical and modified WAsP/park models show promise; however, these require further development/evaluation. For the flow downwind of the wind farm, several intermediate‐scale models fit the available data rather well, and may be candidates for the other half of the two‐model complex which we aim at building.

Published: June 2009

AbstractRapid profiling of fatty acid methyl esters (FAME) from five different animal sources was examined in this study using fast comprehensive two‐dimensional gas chromatography coupled to time‐of‐flight mass spectrometry (fast GC × GC–TOFMS). The result showed that GC × GC analysis combining two different microbore columns (SLB‐5 ms, 10 m × 0.10 mm × 0.10 µm and DBWax, 0.5 m × 0.10 mm × 0.10 µm) allowed three‐fold faster analysis times than those observed for conventional GC × GC analysis. The modulation ratio (MR) of the system was defined at the value of 2.38 by optimizing the modulation period and offset temperature for precise mass spectral identification and highest effluent resolution in the analysis. In accordance with the normalized FAME level obtained from various animal fats, namely lard (LA), chicken fat (CF), beef tallow (BF), mutton tallow (MF) and cod liver oil (CLO), a clear discrimination of LA from the other species by principal components analysis (PCA) was observed. This was attributed to several FAME constituents involving methyl 6,9,12,15‐heneicosatetraenoate (C21:4n‐6), methyl 11,14‐eicosadienoate (C20:2n‐6), trans‐9,12‐methyl octadecadienoate (C18:2n‐6t), trans‐9‐methyl octadecenoate (C18:1n‐9t) and methyl hexadecanoate (C16:0).

Published: June 2009

AbstractWe studied the differences in the characteristics that typify virgin olive oils produced in three representative zones of Extremadura: Sierra Norte of Cáceres, Serena–Siberia, and Tierra de Barros. A total of 156 samples from those three zones were assayed for fatty acids, triglycerides, sterols, and erythrodiol + uvaol. Statistically significant differences (p < 0.05) were found between the mean values of the parameters corresponding to the three zones. These profiles were then used to classify the varietal origin of the oils using the discriminant functions that had previously been defined by the authors for these parameters. This classification, together with the production data, confirmed the use of the different varieties of olives in the study zones. The results showed Manzanilla Cacereña to be the most used variety in the Sierra Norte of Cáceres zone, Cornezuelo and Verdial de Badajoz with a slight presence of Picual in the Serena–Siberia zone, and Carrasqueña and Morisca in Tierra de Barros.

Published: June 2009

Abstract

Background
Proteomic profiling is a rapidly developing technology that may enable early disease screening and diagnosis. Surface-enhanced laser desorption ionization–time of flight mass spectrometry (SELDI-TOF MS) has demonstrated promising results in screening and early detection of many diseases. In particular, it has emerged as a high-throughput tool for detection and differentiation of several cancer types. This review aims to appraise published data on the impact of SELDI-TOF MS in breast cancer.

Methods
A systematic literature search between 1965 and 2009 was conducted using the PubMed, EMBASE, and Cochrane Library databases. Studies covering different aspects of breast cancer proteomic profiling using SELDI-TOF MS technology were critically reviewed by researchers and specialists in the field.

Results
Fourteen key studies involving breast cancer biomarker discovery using SELDI-TOF MS proteomic profiling were identified. The studies differed in their inclusion and exclusion criteria, biologic samples, preparation protocols, arrays used, and analytical settings. Taken together, the numerous studies suggest that SELDI-TOF MS methodology may be used as a fast and robust approach to study the breast cancer proteome and enable the analysis of the correlations between proteomic expression patterns and breast cancer.

Conclusion
SELDI-TOF MS is a promising high-throughput technology with potential applications in breast cancer screening, detection, and prognostication. Further studies are needed to resolve current limitations and facilitate clinical utility.
Protection of sexual and reproductive health rights: Addressing violence against women
Authors: García‐Moreno Claudia , Stöckl Heidi 
Published: June 2009

AbstractViolence against women is recognized as a global public health and human rights problem in need of urgent attention. It affects women's health, including their sexual and reproductive health, and their human rights. While progress has been made in the last 15 years, there is still a long way to go. International human rights law and public health provide tools to governments and non‐governmental actors to ensure women a life free from violence and its consequences. Health policies and services need to address violence more systematically and health providers must take action. At a minimum, they should be informed and able to respond appropriately to violence, providing appropriate care and referral to other services. Equally, if not more important, is to provide support to interventions that prevent violence against women from happening in the first place.
Identity‐based motivation and consumer behavior
Authors: Oyserman Daphna 
Published: June 2009

AbstractChoices are often identity‐based yet the identity‐to‐choice link is not necessarily obvious for reasons articulated by the identity‐based motivation model (Oyserman, D. (2009). Identity‐based motivation: Implication for action‐readiness, procedural readiness and consumer behavior. Journal of Consumer Psychology). Specifically, which identities are salient and what identities mean in the moment are highly dependent on situational cues. Though they feel stable, identities are dynamically shaped by situational affordances and constraints and this shaping process can occur without conscious awareness. This implies that product use, including use of utilitarian products, can become identity‐based, as can both self‐constructive and self‐destructive choices. Over time, broader identities are more likely to be cued than more narrow ones, though any identity can be cued in the right circumstances. The commentaries apply the model to culture‐contingent effects of power (Shavitt, S., Torelli, C. & Wong, J. (2009). Identity‐based motivation: Constraints and opportunities in consumer research. Journal of Consumer Psychology), charitable giving (Aaker, J. & Akutsu, S. (2009). Why do people give? The role of identity in giving. Journal of Consumer Psychology), and the consequences of salient identities for self‐constructive vs. self‐destructive choices (Kirmani, A. (2009). The self and the brand. Journal of Consumer Psychology) and this commentary addresses some of the questions they raise.
Late Quaternary glaciation of the Tianshan, Central Asia, using cosmogenic 10Be surface exposure dating
Authors: Kong Ping , Fink David , Na Chunguang , Huang Feixin 
Published: June 2009

AbstractGlacial deposits are present at the head of the Ürümqi River valley, Tianshan, Central Asia. 10Be surface exposure ages of 15 boulders from three sites along a 12 km valley transect range from 9 to 21 ka suggesting emplacement by glacial retreat and advance commencing at the global last glacial maximum (LGM) and most likely abating in the early Holocene. Although the age spread for a given locality is not small, perhaps indicating post-depositional reworking, maximum ages per site are either coeval with or are post-LGM and inconsistent with previous pre-LGM electron spin resonance ages.

Authors: GOLZY MOJGAN 
Published: June 2009

AbstractThe main purpose of this paper is to develop a point-free notion of topological transitivity. First, we define transitive frame maps and transitive completely prime filters inFrm, the category of frames and frame maps. Then we discuss the relationship between these notions inFrmand the notions of topological transitive and transitive points inTop. Finally, we investigate the relationship between transitive frame maps and the existence of transitive completely prime filters.

Published: June 2009

AbstractWe discuss here the boundedness of the fractional integral operatorIαand its generalized version on generalized nonhomogeneous Morrey spaces. To prove the boundedness ofIα, we employ the boundedness of the so-called maximal fractional integral operatorIa,κ*. In addition, we prove an Olsen-type inequality, which is analogous to that in the case of homogeneous type.
REILLY INEQUALITIES OF ELLIPTIC OPERATORS ON CLOSED SUBMANIFOLDS

Published: June 2009

AbstractUsing generalized position vector fields we obtain new upper bound estimates of the first nonzero eigenvalue of a kind of elliptic operator on closed submanifolds isometrically immersed in Riemannian manifolds of bounded sectional curvature. Applying these Reilly inequalities we improve a series of recent upper bound estimates of the first nonzero eigenvalue of the Lr operator on closed hypersurfaces in space forms.

Published: June 2009

Although chronic fish oil intervention had been shown to have a positive impact on vascular reactivity, very little is known about their acute effects during the postprandial phase. Our aim was to examine the impact of a fish oil-enriched test meal on postprandial vascular reactivity in healthy younger ( < 50 years) v. older ( ≥ 50 years) men. Vascular reactivity was measured at baseline (0 h), 2 and 4 h after the meal by laser Doppler iontophoresis and blood samples taken at 0 and 4 h for the measurement of plasma lipids, total nitrite, glucose and insulin. Acetylcholine- (ACh, endothelial-dependent vasodilator) and sodium nitroprusside (SNP, endothelial-independent vasodilator)-induced reactivities were greater at 4 h than at baseline or 2 h in the younger men (P < 0·04). These changes were not observed in the older men. Comparison of the male groups revealed significantly greater responses to ACh (P = 0·006) and SNP (P = 0·05) at 4 h in the younger compared with the older males. Postprandial NEFA concentrations were also greater at 4 h in the younger compared with the older men (P = 0·005), with no differences observed for any of the other analytes. Multiple regression analysis revealed age to be the most significant predictor of both ACh and SNP induced reactivity 4 h after the meal. In conclusion, the ingestion of a meal enriched in fish oil fatty acids was shown to improve postprandial vascular reactivity at 4 h in our younger men, with little benefit evident in our older men.
