Prevalence of Mycoplasma genitalium in men with urethritis and in high risk asymptomatic males in Tel Aviv: a prospective study

We sought to investigate the prevalence of Mycoplasma genitalium, Chlamydia trachomatis, Neisseria gonorrhoeae, and Trichomonas vaginalis in men presenting to a sexually transmitted infection (STI) clinic, with special attention to M. genitalium, its occurrence in Israeli patients, coinfections, and risk factors. In a cross-sectional study, 259 men were successively enrolled in the Tel Aviv Levinsky Clinic for STIs between November 2008 and November 2010. There were 118 men with urethritis and 141 high-risk men without symptoms. M. genitalium, C. trachomatis, N. gonorrhoeae, and T. vaginalis were detected using nucleic acid amplification tests. Demographic characteristics and risk factors were documented. The overall prevalence of infection with M. genitalium, C. trachomatis, N. gonorrhoeae, and T. vaginalis, were 6.6%, 12.7%, 23.1%, and 0%, respectively. Prevalences in men with urethritis were 11.9%, 22%, and 49%, for M. genitalium, C. trachomatis, and N. gonorrhoeae, respectively. Prevalences in men without symptoms were 2.1%, 5.0%, and 1.4%, for M. genitalium, C. trachomatis, and N. gonorrhoeae, respectively. Co-infections were found only in symptomatic individuals, in whom 5.9% were infected concomitantly with C. trachomatis and N. gonorrhoeae, and 2.5% had dual infection with M. genitalium and N. gonorrhoeae. N. gonorrhoeae, C. trachomatis, and M. genitalium were significantly more prevalent in patients with urethritis. M. genitalium was significantly more prevalent in the heterosexual population than in homosexual males. To conclude, we have found that M. genitalium infection is associated with urethritis in Israeli men, and more so in the heterosexual population. Testing men for M. genitalium as a cause of non-gonococcal urethritis is warranted, particularly because of its poor response to doxycycline and possible failure of azithromycin.
Application of a Real‐Time PCR‐Based System for Monitoring of O26, O103, O111, O145 and O157 Shiga Toxin‐Producing Escherichia coli in Cattle at Slaughter

Faecal samples were collected from 573 slaughtered cattle aged between three and 24 months in seven abattoirs. After enrichment (mTSB with novobiocin), samples were screened by real‐time PCR first for stx and if positive, tested for the top‐five Shiga toxin‐producing Escherichia coli (STEC) serogroups using PCR assays targeting genes specific for serogroups O26, O103, O111, O145 and O157. Of 563 samples with available results, 74.1% tested positive for stx genes. Amongst them, the serogroups O145, O103, O26, O157 and O111 were detected in 41.9%, 25.9%, 23.9%, 7.8% and 0.8%, respectively. From 95 O26, 166 O145 and 30 O157 PCR‐positive samples, 17 O26, 28 O145 and 12 O157 strains were isolated by colony hybridization after immunomagnetic separation. The 17 O26 strains were eae‐positive, but only nine strains harboured stx (eight possessing stx1 and one stx2). Of the 28 O145 strains, ten were eae‐positive including four harbouring stx1 or stx2, whereas 18 were negative for stx and eae. Five of the 12 O157 strains harboured stx2 and eae, did not ferment sorbitol, and were identified as STEC O157:H7/H−. The other seven O157 strains were negative for stx and eae or positive only for eae. Shiga toxin genes and the top‐five STEC serogroups were frequently found in young Swiss cattle at slaughter, but success rates for strain isolation were low and only few strains showed a virulence pattern of human pathogenic STEC.
Short-circuit failure mechanism of SiC power MOSFETs

Failure mechanisms during short-circuit conditions of Silicon Carbide Power MOSFETs are analysed in this work, and a possible theoretical explanation is provided. Insight into the physics involved in such processes was inferred through experimental and numerical analyses. The TCAD structure used for electro-thermal simulations was calibrated to fit the ID-VGS characteristics of a commercial device. Adequate physical effects were considered, such as the presence of charges and traps at the oxide-SiC interface and their effect on threshold voltage and carrier mobility. Experimental evidences were explained by analyzing the numerical results. The high temperature reached during these operating conditions was addressed as the main cause of the device failure. The effect on the leakage current and the activation of a parasitic bipolar transistor are also shown.
Larval anisakid nematodes of Japanese common squid (Todarodes pacificus) from the Sea of Japan.

Two species of third-stage larvae of the family Anisakidae are described from the Japanese common squid (Todarodes pacificus Steenstrup) from the Sea of Japan. The larvae of 1 of them, Anisakis simplex (Rudolphi, 1809), commonly occur encapsulated in the viscera of squid, whereas those of another 1, identified as Lappetascaris sp. , are found free in the mantle musculature. The latter, characterized by the presence of a very long ventricular appendix, a conspicuous esophageal gland, and the structure of the cephalic end (presence of sclerotized supports of lip anlagen), previously were reported by various authors as members of the genera Contracaecum, Thynnascaris, or Hysterothylacium. It appears that the larvae form the mantle of squid belong to a hitherto undescribed Lappetascaris species whose adults parasitize an, as yet unknown, predatory marine fish.
Distribution of extracellular matrix proteins in indomethacin-induced lesions in the rat stomach.

INTRODUCTION We investigated the distribution of extracellular matrix (ECM) proteins in indomethacin-induced lesions of the rat stomach. METHOD Twenty rats received indomethacin orally at a dose of 8 mg/kg/body weight. The animals were killed at 3, 6, 12, 24, and 48 h after administration of the drug. The stomachs were removed and frozen in liquid nitrogen. Cryostat serial sections of the lesions were immunostained with antibodies to collagen III, IV, and VI, laminin, and fibronectin. RESULTS Fibronectin was the dominant extracellular protein of the provisional ECM in deep gastric lesions and gastric ulcers. Collagen III was strongly positive in stromal cells under the necrotic material in gastric erosions. Basal membrane proteins (collagen IV and laminin) were found to originate from the muscularis mucosae at the ulcer edge. CONCLUSION There is a typical distribution of ECM proteins in erosions and ulcers of the rat stomach. Fibronectin was most prominent in the provisional matrix of gastric erosions and ulcers.
Physical limitations and depressive symptoms: exploring the nature of the association.

OBJECTIVES Although evidence suggests that physical disability and depression may be reciprocally related, questions of causality versus spuriousness and the direction of causality remain to be confidently answered. This study considered the hypothesis of reciprocal influence; the possibility of spuriousness in relation to pain, stress, and lifetime major depression; and the possible mediating effects of pain and social stress. METHODS We analyzed data from a two-wave panel study of Miami-Dade County residents (n = 1,455) that included a substantial oversampling of individuals reporting a physical disability. RESULTS Results indicated that, although prior levels of physical limitations predicted changes in depressive symptoms, there was no evidence of the reverse association. Results also indicated that part of the association between prior physical limitations and changes in depressive symptoms was explained by intervening level of pain and, to a lesser extent, by the day-to-day experience of discrimination. DISCUSSION Much of whatever causation may be involved in the linkage between physical limitations and depressive symptomatology flows from limitations to depression rather than in the reverse direction. Results also make clear that this linkage is not an artifact of shared associations with pain, social stress, or lifetime major depression.
Modern alongside traditional taxonomy—Integrative systematics of the genera Gymnangium Hincks, 1874 and Taxella Allman, 1874 (Hydrozoa, Aglaopheniidae)

We studied the diversity within the former genus Gymnangium in the South West Indian Ocean by using an integrative approach of both traditional (morphology-based) and modern molecular taxonomy. Nine species were recorded in the material collected. A total of 97 16S mitochondrial DNA sequences and 54 Calmodulin nuclear sequences from eight Gymnangium/Taxella species were analyzed. We found both morphological and molecular differences in the studied Gymnangium species that make it necessary to split the genus. It is proposed to revalidate the genus Taxella which is currently regarded as a synonym of Gymnangium. Two species of the genus Taxella (T. eximia and T. gracilicaulis), until now regarded as distinct species based on morphological characteristics, cluster together in one phylogenetic clade. Possible explanations are discussed. Two species from Madagascar new to science are herein described and rare species from the Indian Ocean islands are re-described.
Sex differences in the preattentive processing of vocal emotional expressions

Emotional tone of voice indicates the significance of a spoken utterance. We asked whether listeners recognize this significance even when attending to something else and whether men and women differ in this regard. To answer these questions, we presented emotionally or neutrally spoken syllables as standards and deviants in a mismatch negativity paradigm. Independent of the listeners' sex, deviants elicited a mismatch negativity in the scalp-recorded event-related potential as an indicator of preattentive acoustic change detection. Only women, however, showed a larger mismatch negativity to emotional than to neutral deviants. Thus, even though both sexes detect change in voice preattentively, only women recruit additional processing resources when the change in voice is one of emotional valence.
THE COMPARISON OF EMOTIONAL INTELLIGENCE AND HARDINESS IN ADDICTS AND NON-ADDICTS

Substance abuse, also known as drug abuse, is a chronic phenomenon entailing many physical, psychological, social, familial, and economic damages so that the addicted person’s social and individual actions are severely reduced. The main purpose of this paper is to compare the emotional intelligence and hardiness in addicts and non-addicts. The sample consisted of 80 drug addicts and 80 normal individuals. The sample size of addicts was determined using convenience sampling method in addiction treatment center of Kermanshah-Iran. Then, the cloning method was used to match the two groups based on the variables of age, education level, number of family members, and family income. The participants answered Petrides and Furnham’s emotional intelligence questionnaire as well as Kobasa's 80-item hardiness questionnaire. Then the data were analyzed using statistical tests. The analysis of data showed that there is a significant difference between addicts and non-addicts in terms of emotional intelligence and hardiness so that the emotional intelligence and hardiness of addicts are lower than the normal group. Also, the level of all emotional intelligence components (optimism, understanding one's own and others’ emotions, controlling emotions, and social skills) was lower in addicts compared to non-addicts. The same results were obtained regarding the individuals hardiness; in other words, the addicted participants obtained lower scores in all hardiness components (commitment, challenge, and control). The other results of this research showed that there is a significant and negative relation between the duration of addiction and emotional intelligence as well as between the duration of addiction and hardiness. Finally, it was concluded that addicts have lower emotional intelligence and hardiness compared to normal individuals; also, there is a significant relation between the emotional intelligence and hardiness in addicts and normal individuals (p<0.05).
Parental Perception of Weight Status: Influence on Children’s Diet in the Gateshead Millennium Study

Objective Recognising overweight and obesity is critical to prompting action, and consequently preventing and treating obesity. The present study examined the association between parental perceptions of child weight status and child’s diet. Methods Participants were members of the Gateshead Millennium Study. Parental perception of their child’s weight status was assessed using a questionnaire and compared against International Obesity Task Force cut-offs for childhood overweight and obesity when the children were aged 6–8 years old. Diet was assessed at age 6-8years old using the FAST (Food Assessment in Schools Tool) food diary method. The association between parental perception and dietary patterns as defined by Principal Components Analysis, was assessed using multivariate regression after adjustment for child’s gender, child’s weight status, maternal body mass index (BMI), maternal education and deprivation status. Results Of the 361 parents who provided complete data on confounders and on their perception of their child’s weight status, 63 (17%) parents perceived their child as being of ‘normal’ weight or ‘overweight’ when they were actually ‘overweight’ or ‘obese’, respectively. After adjustment for confounders, parents who misperceived their child’s weight had children with a lower ‘healthy’ dietary pattern score compared to children whose parents correctly perceived their weight (β = -0.88; 95% CI: -1.7, -0.1; P-value = 0.028). This association was found despite higher consumption of reduced sugar carbonated drinks amongst children whose parents incorrectly perceived their weight status compared to children whose parents perceived their weight correctly (52.4% vs. 33.6%; P-value = 0.005). Conclusions In conclusion, children whose parents did not correctly perceive their weight status scored lower on the ‘healthy’ dietary pattern. Further research is required to define parents’ diets based on their perception status and to examine if a child’s or parent’s diet mediates the association between parental perception and child weight.
Two-Dimensional Compact Inversion of Magnetic Data in the Presence of Remanent Magnetization

Remnant magnetization causes a change in the direction and intensity of the magnetization vector. If inversion is performed regardless of remnance, in some cases it may have unreliable and misleading results. For inversion with respect to remnant magnetization, several solutions have been proposed so far, one of which is to convert the data of total magnetic field into data that is independent of the direction of magnetization. In this study, the transformation of Total Field Anomaly (TFA) into Total Magnitude Anomaly (TMA) is used. The inversion algorithm is based on improving compact inversion method and is just two-dimensional. In compact inversion, anomalies may concentrate on the surface of the earth, and thus the response is unreliable. To solve this problem, a combination of matrices and weighting functions have been used, including elements such as magnetic susceptibility and depth function. The resulting model can be smooth or compact (with sharp edges) based on changing compactness factor. The method has been tested using several synthetic and real data. The synthetic data are a 2D tabular prism, of which the top buried-depth is 20 m and the length and width are 40 to 20 m, a dipping prism with a vertical tabular nearby. The real example is magnetic data over Galinge iron-ore deposit in Qinghai province of China, and the data of four profiles have been considered for 2D inversion. Inversion even smooth or sharp, have been conducted with all models, and especially sharper models are consistent with the known geologic attributes of the magnetic sources.
O EXAME DE SUFICIÊNCIA EM CONTABILIDADE: UMA AVALIAÇÃO SOB A PERSPECTIVA DOS PESQUISADORES

Com o crescimento do ensino superior no Brasil, observa-se que o seu processo de avaliação foi ampliado com ações públicas como o Exame Nacional de Desempenho de Estudantes (ENADE), e de órgãos de classe profissional. O objetivo da pesquisa foi identificar a percepção de docentes e profissionais sobre o exame de suficiência para a profissão contábil, bem como avaliar seu atual modelo. O estudo foi descritivo e a coleta de dados foi desenvolvida por meio de uma websurvey com 1.185 autores de artigos apresentados em congressos e periódicos da área contábil. A amostra foi composta de 41,5% de pesquisadores que atuam como docentes, 29,1% atuam apenas como profissionais de mercado e 29,4% atuam nas duas áreas. Como resultado, a pesquisa apontou uma taxa de concordância de 90% com a exigência da prova, porém 57,7% entendem que a prova deveria ter revalidações periódicas, e 84,6% entendem que além do exame os profissionais deveriam comprovar atualização continuada. Com relação ao modelo que a prova é aplicada, 53% dos entrevistados concordam que é adequado. De maneira geral as questões aplicadas no exame foram consideradas medianas, mas cerca de 70% dos docentes costumam utilizá-las em maior ou menor grau em suas atividades didáticas. Os docentes entendem que bons resultados nestes exames têm importâncias para a imagem das Instituições de Ensino Superior.
METABOLIC HEAT PRODUCTION BY ARTEMIA EMBRYOS UNDER ANOXIC CONDITIONS

The metabolic status of encysted Artemia embryos under anoxic conditions has been studied by calorimetry. Previous work demonstrated a very low, but still measurable, source of metabolic heat (31 nW mg-1 dry mass) after 6 days of anoxia, attributed to the catabolism of small amounts of carbohydrate storage compounds and the unusual nucleotide diguanosine tetraphosphate. Our results indicate that the heat measured drops below the detection limits of our calorimeter (11 nW mg-1 dry mass) after 1.5 h of anoxia, in sharp contrast with previously published results. The possible sources of error that could explain this difference, and a re-evaluation of the metabolic status of cysts during anoxia, are discussed. We conclude that if the cysts are carefully protected from oxygen they become essentially ametabolic.
REVISITING HOGUP CAVE, UTAH: INSIGHTS FROM NEW RADIOCARBON DATES AND STRATIGRAPHIC ANALYSIS

The remarkable finds from the trans-Holocene archaeological record excavated at Hogup Cave, Utah, helped define our understanding of Great Basin prehistory. However, many scholars doubt the integrity of the site's depositional sequence and resulting chronological interpretations. To resolve these concerns, we produce several Bayesian chronological models combining 14 new radiocarbon dates with the results of past dating efforts. We first present an examination of the excavation and previously derived dates, finding that several of the most anomalous dates can be accounted for by details in the excavation's field notes. We then report our new dates and construct an initial Bayesian chronological model to serve as a framework for three increasingly complex models synthesizing old and new dates from the site. The best-supported model divides the site's stratigraphy into four occupational phases: Strata 1 through 7 (9790 to 6490 cal B.P.), Stratum 8 (5840 to 3330 cal B.P.), Strata 9 and 10 (2870 to 2760 cal B.P.), and Strata 11 through 16 (2610 to 360 cal B.P.). This result raises several questions to direct future research and dating efforts at Hogup Cave and serves as a model for reevaluating complex stratigraphic sequences in western North America and beyond. Los descubrimientos excepcionales del registro arqueológico trans-Holoceno excavado en Hogup Cave, Utah, han ayudado a definir nuestro entendimiento de la prehistoria de la Gran Cuenca. Sin embargo, muchos estudiosos dudan la integridad de la secuencia deposicional del yacimiento y, por consiguiente, la validez de las interpretaciones resultantes. Para resolver este problema, se produjeron varios modelos cronológicos bayesianos que combinan 14 nuevas fechas de radiocarbono con las fechas procedentes de trabajos anteriores. En primer lugar se presenta un análisis de la excavación y de las fechas obtenidas anteriormente, demostrando que varias de las fechas más anómalas son explicadas en las notas de excavación. Luego se reportan las nuevas fechas y se presenta un modelo cronológico bayesiano inicial que es utilizado como marco de referencia para producir tres modelos cada vez más complejos que sintetizan las fechas anteriores y las más recientes. El modelo más consistente divide la estratigrafía del yacimiento en cuatro etapas de ocupación: los niveles 1–7 (9790-6490 cal a.P.), el nivel 8 (5840-3330 cal a.P.), los niveles 9–10 (2870-2760 cal a.P.) y los niveles 11–16 (2610-360 cal a.P.). Este resultado genera varias preguntas para guiar las investigaciones futuras en Hogup Cave y sirve como modelo para reevaluar las secuencias estratigráficas complejas en el oeste de Norteamérica y otras regiones.
Indications for first caesarean and delivery mode in subsequent trial of labour.

BACKGROUND A previous caesarean delivery is no longer an indication per se for a subsequent, planned caesarean. We performed this study to identify women suitable for trial of labour after caesarean (TOLAC), investigating the association between the indication for the first caesarean and the risk of unplanned caesarean in the second pregnancy. METHODS We identified women with their first two pregnancies registered in the Swedish Medical Birth Registry 1992-2007. The indications for caesarean in the first pregnancy were determined using a previously published hierarchical system. For each indication group, the rate of caesarean among women with a first caesarean (n = 59 643) and a TOLAC in the second pregnancy was compared with that of primiparae (parity 0) (n = 354 053). RESULTS The TOLAC rate was 69.5%. Among women with TOLAC, the uterine rupture rate was 1.1%. The success rate of TOLAC varied substantially based on the indication for the first caesarean (range 51-83%). Multiple births, breech presentation, and placenta praevia in the first pregnancy were associated with marginally increased odds of unplanned caesarean in the second pregnancy when compared with primiparae (adjusted OR 1.27 [95% CI 1.10, 1.48], 1.42 [1.34, 1.51], and 1.65 [1.17, 2.31]; OR, odds ratio; CI, confidence interval). The indications based on complications during labour/delivery, macrosomia, and maternal diabetes, were associated with substantially increased OR: 3.87 [3.70, 4.06], 4.15 [3.74, 4.61], and 4.62 [3.79, 5.63], respectively. CONCLUSIONS Considering the indications for caesarean in the first pregnancy before recommending a TOLAC or a planned caesarean in the second pregnancy may help to lower the rate of unplanned caesarean deliveries.
Viscosity and growth response of broilers fed high fiber diets supplemented with a corn-produced recombinant carbohydrase

SUMMARY Feed ingredients containing high levels of non-starch polysaccharides (NSP), such as wheat and corn distillers’ dried grains with solubles (DDGS), can form viscous digesta in the gastrointestinal tract, limiting broiler performance. A study was conducted to determine efficacy of a corn-produced recombinant carbohydrase (AC1) on dietary and intestinal viscosity and broiler performance with a high NSP diet. Hubbard × Ross 708, a day old, male broiler chicks (n = 960) were fed 1 of 8 dietary treatments for 21 d. Diets included a corn–soybean meal based diet (PC_1) and a diet of similar essential nutrient density, but with a 10% inclusion of both wheat and DDGS (PC_2) and a negative control (NC) with similar ingredients as PC_2, but with ME reduced by 125 kcal/kg. Additional treatments had varying levels of AC1, supplying 50, 100, 200, 400, or 600 U β-Glucanase (β-Glu-U) per kg of feed, mixed into the NC diet. Dietary and digesta (d14) viscosity and weekly bird performance were measured. The inclusion of wheat and DDGS increased d1–7 feed conversion ratio (FCR) and supplementing AC1 at 50–400 β-Glu-U/kg reduced FCR equivalent to PC_1. Intestinal viscosity correlated with d1–21 FCR and inversely correlated with d1–21 live weight gain (LWG). When analyzed categorically, dietary viscosity inversely correlated with d1–21 LWG (P
