Health-related quality of life and symptom profiles of female survivors of sexual abuse.

OBJECTIVES To determine the association between severity of sexual abuse and psychiatric or medical problems in a sample of female patients from primary care medical settings and to assess the relationship between sexual abuse severity and health-related quality of life before and after controlling for the effects of a current psychiatric or medical diagnosis. DESIGN Structured interview and self-report questionnaire. SETTING Three family practice outpatient clinics. SUBJECTS A total of 252 women selected by somatization status using a screen for unexplained physical symptoms. MAIN OUTCOME MEASURES Patient assessment after administering the Medical Outcomes Study 36-item Short-Form Health Survey and self-report medical problems questionnaire; the quality-of-life scale developed by Andrews and Withey; Diagnostic and Statistical Manual of Mental Disorders, Third Edition, Revised, diagnoses and symptom counts from the Diagnostic Interview Schedule; the Dissociative Experiences Scale; and the modified Dissociative Disorders Interview Schedule. RESULTS A history of sexual abuse is associated with substantial impairment in health-related quality of life and a greater number of somatized symptoms (P < .001), medical problems (P < .01), and psychiatric symptoms and diagnoses (P < .001). In regression analyses, sexual abuse severity was a significant predictor of high scores on 6 of the 8 subscales of the Medical Outcomes Study Short-Form Health Survey (P < .05) and all of the quality-of-life subscales developed by Andrews and Withey (P < .01), with average decrements of up to 0.41 SDs for moderately abused women and 0.56 SDs for severely abused women. Furthermore, sexual abuse severity remained a significant predictor of high scores on the subscales mental health (P < .05), social functioning (P < .05), and quality of life (P < .05), even after adjusting for the presence of several common psychiatric diagnoses. CONCLUSIONS Female primary care patients with a history of sexual abuse have more physical and psychiatric symptoms and lower health-related quality of life than those without previous abuse. In addition, a linear relationship exists between the severity of sexual abuse and impairment in health-related quality of life, both before and after controlling for the effects of a current psychiatric diagnosis.
Duplex PCR for Differential Identification of Mycobacterium bovis, M. avium, and M. avium subsp.paratuberculosis in Formalin- Fixed Paraffin-Embedded Tissues from Cattle

ABSTRACT We previously isolated and sequenced two genomic segments ofMycobacterium avium subsp. paratuberculosis, namely, f57, a species-specific sequence, and the p34 gene, coding for a 34-kDa antigenic protein. Comparison of sequences upstream of the p34 open reading frame (us-p34) from M. avium subsp.paratuberculosis and M. tuberculosisshowed a 79-base deletion in M. tuberculosis. Sequence analysis of the p34 genes in another two species, M. bovis(strain BCG) and M. avium (strain D4), confirmed the differences observed between tuberculous and nontuberculous species. A duplex diagnostic PCR strategy based on coamplification of nonhomologous us-p34 and species-specific f57 sequences was therefore developed. Duplex PCR yielded three different patterns, specific either for tuberculous bacilli (M. tuberculosis, M. bovis, and M. africanum), for both nontuberculous mycobacteria M. avium and M. intracellulare, or for M. avium subsp. paratuberculosis. The specificity of this single-step DNA-based assay was assessed on DNA from cultured mycobacterial strains, as well as on a panel of formalin-fixed and paraffin-embedded tissues from cattle. Molecular assay results from tissular DNA were compared to conventional bacteriological and histological test results, including those obtained by Ziehl-Neelsen staining on tissue biopsy specimens. Molecular discrimination was successful and confirmed the value of duplex us-p34 and f57 sequence amplification for differential diagnosis of tuberculosis, paratuberculosis, or infections caused by other members of the M. avium complex.
The Speed of Exchange Rate Pass-Through

On January 15, 2015, the Swiss National Bank discontinued its minimum exchange rate policy of 1 euro against 1.2 Swiss francs. This policy change resulted in a sharp, unanticipated, and permanent appreciation of the Swiss franc by more than 11% against the euro. We analyze the pass-through of this unusually clean exchange rate shock into import unit values at the daily frequency using Swiss transaction-level trade data. Our key findings are twofold. First, for goods invoiced in euros, the pass-through is immediate and complete. Second, for goods invoiced in Swiss francs, the pass-through is partial and exceptionally fast: beginning on the second working day after the exchange rate shock, the medium-run pass-through is reached after 12 working days.
Sildenafil Induces Delayed Preconditioning Through Inducible Nitric Oxide Synthase–Dependent Pathway in Mouse Heart

Sildenafil citrate (Viagra) is the most widely used drug for treating erectile dysfunction in men. We recently demonstrated that it induces potent protective effects against ischemia-reperfusion (I-R) injury in rabbit hearts through the opening of mitochondrial ATP-dependent K+ channels. In the present study, we investigated the role of the NO-dependent signaling pathway in delayed cardioprotection by sildenafil. Adult male ICR mice were treated with saline or sildenafil (0.7 mg/kg IP) 24 hours before global I-R in the Langendorff mode. Infarct size was reduced from 27.6±3.3% in saline-treated control mice to 6.9±1.2% in sildenafil-treated mice (mean±SEM, P <0.05) without compromising cardiac function. Reverse transcription–polymerase chain reaction revealed a transient increase in endothelial and inducible NO synthase (eNOS and iNOS, respectively) mRNA in sildenafil-treated mice, peaking at 45 minutes (eNOS) and 2 hours (iNOS) after sildenafil injection. The magnitude of mRNA increase was more pronounced for iNOS than for eNOS. In addition, a significant increase in both iNOS and eNOS protein was detected 24 hours after sildenafil treatment. A selective inhibitor of iNOS, 1400W (10 mg/kg IP given 30 minutes before I-R), abolished sildenafil-induced protection (23.7±2.8%, P <0.05 versus sildenafil). These data suggest that the induction of NO synthase isoforms is an essential component of the signaling mechanism for sildenafil-induced delayed preconditioning. However, iNOS appears to be the primary isoform that mediates the robust cardioprotection.
The Role of Attention Shifting in Orthographic Competencies: Cross-Sectional Findings from 1st, 3rd, and 8th Grade Students

Attention shifting refers to one core component of executive functions, a set of higher-order cognitive processes that predict different aspects of academic achievement. To date, few studies have investigated the role of attention shifting in orthographic competencies during middle childhood and early adolescence. In the present study, 69 first-grade, 121 third-grade, and 85 eighth-grade students' attention shifting was tested with a computer version of the Dimensional Change Card Sort (DCCS; Zelazo, 2006). General spelling skills and specific writing and spelling strategies were assessed with the Hamburger Writing Test (May, 2002). Results suggested associations between attention shifting and various orthographic competencies that differ across age groups and by sex. Across all age groups, better attention shifting was associated with less errors in applying alphabetical strategies. In third graders, better attention shifting was furthermore related to better general spelling skills and less errors in using orthographical strategies. In this age group, associations did not differ by sex. Among first graders, attention shifting was negatively related to general spelling skills, but only for boys. In contrast, attention shifting was positively related to general spelling skills in eighth graders, but only for girls. Finally, better attention shifting was associated with less case-related errors in eighth graders, independent of students' sex. In sum, the data provide insight into both variability and consistency in the pattern of relations between attention shifting and various orthographic competencies among elementary and middle school students.
Rotaviruses specifically bind to the neutral glycosphingolipid asialo-GM1

Rotaviruses are the major etiologic agents of severe diarrhea in children. Many rotaviruses encode a hemagglutinin which binds to sialic acids. We report that rotaviruses specifically recognize the neutral glycosphingolipid gangliotetraosylceramide (asialo-GM1 or GA1). GA1 resolved by thin-layer chromatography is bound by rotavirus, and binding is blocked by neutralizing rotavirus antiserum. Similar glycosphingolipid structures, such as globoside, gangliotriaosylceramide, and GA1 oxidized with galactose oxidase are ineffective in binding rotavirus. Other enteric viruses also specifically bind GA1. GA1 adsorbed to polystyrene beads inhibits rotavirus replication in vitro (as do anti-GA1 antibodies). The use of orally administered immobilized GA1 or anti-GA1 antibodies may prove useful in preventing or attenuating rotaviral and other enteric viral infections.
Structure and Regulatory Profile of the Monkeypox Inhibitor of Complement: Comparison to Homologs in Vaccinia and Variola and Evidence for Dimer Formation1

The outbreak of monkeypox in the Unites States in the summer of 2003 was the first occurrence of this smallpox-like disease outside of Africa. This limited human epidemic resulted from cross-infection of prairie dogs by imported African rodents. Although there were no human fatalities, this outbreak illustrates that monkeypox is an emerging natural infection and a potential biological weapon. We characterized a virulence factor expressed by monkeypox (monkeypox inhibitor of complement enzymes or MOPICE). We also compared its structure and regulatory function to homologous complement regulatory proteins of variola (SPICE) and vaccinia (VCP). In multiple expression systems, 5–30% of MOPICE, SPICE, and VCP consisted of function-enhancing disulfide-linked homodimers. Mammalian cells infected with vaccinia virus also expressed VCP dimers. MOPICE bound human C3b/C4b intermediate to that of SPICE and VCP. Cofactor activity of MOPICE was similar to VCP, but both were ∼100-fold less efficient than SPICE. SPICE and VCP, but not MOPICE, possessed decay-accelerating activity for the C3 and C5 convertases of the classical pathway. Additionally, all three regulators possessed heparin-binding capability. These studies demonstrate that MOPICE regulates human complement and suggest that dimerization is a prominent feature of these virulence factors. Thus, our data add novel information relative to the functional repertoire of these poxviral virulence factors. Furthermore, targeting and neutralizing these complement regulatory active sites via mAbs is a therapeutic approach that may enhance protection against smallpox.
The prevalence of compulsive buying: a meta-analysis.

AIMS To estimate the pooled prevalence of compulsive buying behaviour (CBB) in different populations and to determine the effect of age, gender, location and screening instrument on the reported heterogeneity in estimates of CBB and whether publication bias could be identified. METHODS Three databases were searched (Medline, PsychInfo, Web of Science) using the terms 'compulsive buying', 'pathological buying' and 'compulsive shopping' to estimate the pooled prevalence of CBB in different populations. Forty studies reporting 49 prevalence estimates from 16 countries were located (n = 32,000). To conduct the meta-analysis, data from non-clinical studies regarding mean age and gender proportion, geographical study location and screening instrument used to assess CBB were extracted by multiple independent observers and evaluated using a random-effects model. Four a priori subgroups were analysed using pooled estimation (Cohen's Q) and covariate testing (moderator and meta-regression analysis). RESULTS The CBB pooled prevalence of adult representative studies was 4.9% (3.4-6.9%, eight estimates, 10,102 participants), although estimates were higher among university students: 8.3% (5.9-11.5%, 19 estimates, 14,947 participants) in adult non-representative samples: 12.3% (7.6-19.1%, 11 estimates, 3929 participants) and in shopping-specific samples: 16.2% (8.8-27.8%, 11 estimates, 4686 participants). Being young and female were associated with increased tendency, but not location (United States versus non-United States). Meta-regression revealed large heterogeneity within subgroups, due mainly to diverse measures and time-frames (current versus life-time) used to assess CBB. CONCLUSIONS A pooled estimate of compulsive buying behaviour in the populations studied is approximately 5%, but there is large variation between samples accounted for largely by use of different time-frames and measures.
Weight Sharing is Crucial to Succesful Optimization

Exploiting the great expressive power of Deep Neural Network architectures, relies on the ability to train them. While current theoretical work provides, mostly, results showing the hardness of this task, empirical evidence usually differs from this line, with success stories in abundance. A strong position among empirically successful architectures is captured by networks where extensive weight sharing is used, either by Convolutional or Recurrent layers. Additionally, characterizing specific aspects of different tasks, making them "harder" or "easier", is an interesting direction explored both theoretically and empirically. We consider a family of ConvNet architectures, and prove that weight sharing can be crucial, from an optimization point of view. We explore different notions of the frequency, of the target function, proving necessity of the target function having some low frequency components. This necessity is not sufficient - only with weight sharing can it be exploited, thus theoretically separating architectures using it, from others which do not. Our theoretical results are aligned with empirical experiments in an even more general setting, suggesting viability of examination of the role played by interleaving those aspects in broader families of tasks.
Post-source decay fragment spectra of cyclomalto-octaose and branched cyclomalto-hexaose by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry.

gamma-Cyclodextrin, maltosyl-alpha-cyclodextrin and diglucosyl-alpha-cyclodextrin were analyzed using matrix-assisted laser desorption/ionization time-of-flight (MALDI-TOF) mass spectrometry. All of these compounds have the same molecular weight (M.W. = 1297.15) and consist of only D-glucopyranose. From a comparison of the intensities in the post-source decay (PSD) fragment spectra of these cyclodextrin derivatives, correlation between the chemical structures and the relative intensities in the PSD fragment ions was found. The correlation is considered to be caused by the difference in the number of cleavage sites at the glycosyl binding. It was found that the intensity of the PSD ion resulting from one cleavage is higher than that resulting from two cleavages at a glycosyl bond. The results show that PSD fragment-ion spectrum method used in MALDI-TOF mass spectrometry is a very powerful technique for the structural analyses of the sugar-substituted cyclodextrins.
Prospective evaluation of early cardiac damage induced by epirubicin-containing adjuvant chemotherapy and locoregional radiotherapy in breast cancer patients.

PURPOSE To evaluate prospectively the cardiotoxic effects of epirubicin-containing adjuvant chemotherapy in breast cancer patients. PATIENTS AND METHODS Patients (median age, 46 years; range, 28 to 55 years) were treated with five cycles of fluorouracil, epirubicin (90 mg/m2), and cyclophosphamide (FEC) (group I, n = 21) or with four cycles of FEC followed by high-dose chemotherapy consisting of cyclophosphamide, thiotepa, and carboplatin (group II, n = 19). Locoregional radiotherapy was applied subsequently. Cardiac evaluation was performed before chemotherapy (T0), 1 month after chemotherapy, 1 month after radiotherapy (T2), and 1 year after start of chemotherapy (T3). Left ventricular ejection fraction (LVEF) was determined by radionuclide ventriculography and diastolic function by echocardiography. Autonomic function was assessed by 24-hour ECG registration for heart rate variability (HRV) analysis. Time-corrected QT (QTc) was assessed and N-terminal atrial natriuretic peptide (NT-ANP) and brain natriuretic peptide (BNP) were measured as biochemical markers of cardiac dysfunction. RESULTS No patient developed overt congestive heart failure (CHF) and the mean LVEF declined from 0.61 at T0 to 0.54 at T3 (P =.001), resulting in an LVEF below 0.50 (range, 0.42 to 0.49) in 17% of the patients, whereas 28% had a decline of more than 0.10. Plasma NT-ANP levels increased gradually from 237 pmol/L at T0 to 347 pmol/L at T3 (P <.01), whereas plasma BNP levels increased from 2.9 pmol/L to 5.1 pmol/L (P =.04). Mean QTc increased from 406 msec at T0 to 423 msec at T3 (P <.01). No persistent alterations were found in diastolic function and HRV. CONCLUSION Relatively low doses of epirubicin in adjuvant chemotherapy for breast cancer results in mild subclinical myocardial damage demonstrated by a decline in LVEF, an increase in natriuretic peptide levels, and an increase in QTc, which may indicate a long-term risk of CHF.
Center index method—an alternative for wear measurements with radiostereometry (RSA)

Radiostereometry (RSA) is considered to be the most precise and accurate method for wear‐measurements in total hip replacement. Post‐operative stereoradiographs has so far been necessary for wear measurement. Hence, the use of RSA has been limited to studies planned for RSA measurements. We compared a new RSA method for wear measurements that does not require previous radiographs with conventional RSA. Instead of comparing present stereoradiographs with post‐operative ones, we developed a method for calculating the post‐operative position of the center of the femoral head on the present examination and using this as the index measurement. We compared this alternative method to conventional RSA in 27 hips in an ongoing RSA study. We found a high degree of agreement between the methods for both mean proximal (1.19 mm vs. 1.14 mm) and mean 3D wear (1.52 mm vs. 1.44 mm) after 10 years. Intraclass correlation coefficients (ICC) were 0.958 and 0.955, respectively (p < 0.001 for both ICCs). The results were also within the limits of agreement when plotted subject‐by‐subject in a Bland–Altman plot. Our alternative method for wear measurements with RSA offers comparable results to conventional RSA measurements. It allows precise wear measurements without previous radiological examinations. © 2012 Orthopaedic Research Society. Published by Wiley Periodicals, Inc. J Orthop Res 31: 480–484, 2013
The Disbursement Pattern of Japanese Foreign Aid: A Reappraisal

Three perspectives on the determinants of Japan's official development assistance (ODA) program are often represented as distinct, valid explanations of the aid program. Yet few studies have attempted to simultaneously test the hypotheses generated from all three perspectives in a global study of Japanese aid flows. This study seeks to improve the understanding of the Japanese ODA program by addressing some of the gaps in the existing literature. Providing a comprehensive analysis, the article investigates the effects of different political and economic variables on Japanese aid disbursement in eighty-six countries in Africa, Asia, Latin America, and the Middle East from 1979 to 2002. The findings of the study make several contributions to the literature. First, the results provide strong support for the claim that humanitarian concerns, as measured by poverty and human rights conditions in recipient countries, are important determinants of aid allocation. Second, although much of the previous literature has hypothesized that Japan's aid program seeks to promote Japan's economic interests, little empirical support for this view is found in the present study. Likewise, the disbursement pattern of ODA was associated with only a limited number of US security interests; US economic interests are shown to have no effect on ODA.
Oleuropein induced apoptosis in HeLa cells via a mitochondrial apoptotic cascade associated with activation of the c-Jun NH2-terminal kinase.

Oleuropein could inhibit growth and/or induce apoptosis in several cancer cell lines. In this study, we investigate how oleuropein strongly induces apoptotic cell death in HeLa human cervical carcinoma cells. Oleuropein induced HeLa cells apoptosis as demonstrated by induction of a sub-G(1) peak in flow cytometry and apoptosis-related morphological changes observed by fluorescence microscopy after being stained by Hoechst 33324. The results also showed that 150 - 200 μM oleuropein–treated HeLa cells were arrested at the G(2)/M phase. Western blot analysis revealed that the phosphorylated ATF-2, c-Jun NH(2)-terminal kinase (JNK) protein, p53, p21, Bax, and cytochrome c protein in the cytoplasm significantly increased in a dose-dependent manner after treatment of oleuropein for 24 h. Additionally, increasing levels of Bax in response to JNK/SPAK signaling, which formed mitochondrial membrane channels, accounted for releasing of cytochrome c and activation of caspase-9 and -3. SP600125 (20 μM), a JNK(1/2) inhibitor, markedly suppressed the formation of apoptotic bodies and JNK activation induced by oleuropein at 200 μM. Thus, oleuropein-induced apoptosis was activated by the JNK/SPAK signal pathway. The result shows that oleuropein holds promise as a potential chemotherapeutic agent for the treatment of HeLa cells.
Effect of cigarette smoking on copper, lead, and cadmium accumulation in human lens

AIM To identify cigarette smoking as a risk factor for development of cataract, to determine the importance of copper, lead, and cadmium in cataractogenesis, and to learn about any relation between those elements. METHODS Copper, lead, and cadmium concentrations were measured by atomic absorption spectrophotometry in 37 cataractous and nine normal human lenses. RESULTS All three element accumulations in lenses with cataract were statistically meaningful. Lenticular copper, lead, and cadmium were increased significantly with cigarette smoking. Cadmium had a positive correlation both with lead and copper in cataractous lenses. CONCLUSION The accumulation of copper, lead, and cadmium occurs in cataract. The probable source of cadmium in humans is cigarettes. Lenticular cadmium accumulation also increases copper and lead precipitation in the lens. Cigarette smoking might be cataractogenic.
