    The Conference was organized to celebrate the 50th anniversary of the cervical smear test, commonly referred to as the `Pap test` after its creator, George Nicholas Papanicolaou. The reports present the development of the test, its worldwide application, and its performance as the screening test for the detection of cervical cancer. Pap smear screening for precursors of carcinoma of the cervix has led to dramatic decrease in the incidence and deaths from this cancer. The test represents one of the greatest achievements in preventive medicine.

    To conduct a trend analysis of Pap test practices, Pap test results and related women's services and guidelines of college health centers. College health centers who participated in the annual ACHA Pap Test and STI (sexually transmitted infection) Survey years 2004-2014 (n ranged from 127 to 181 depending on year). Descriptive analyses are presented with ANOVAs (Analysis of Variance) and chi-square tests calculated to examine trends over time. The number of Pap tests significantly decreased over time; however, the percentage of normal and HSIL (high-grade squamous intraepithelial lesion) results did not vary. Availability of conventional cytology slides and cryotherapy were significantly associated with year. Over time, college health centers' guidelines related to initiation of Pap testing evolved to consistently conform to national recommendations for cervical screening. The results indicate most college health centers are following the current national guidelines regarding Pap testing for young adult women.

    Full Text Available Rare entities in the Pap test, including neoplastic and non-neoplastic conditions, pose challenges due to their infrequent occurrence in the daily practice of cytology. Furthermore, these conditions give rise to important diagnostic pitfalls. Infections such as tuberculosis cervicitis may be erroneously diagnosed as carcinoma, whereas others, such as schistosomiasis, are associated with squamous cell carcinoma. These cases include granuloma inguinale (donovanosis, tuberculosis, coccidioidomycosis, schistosomiasis, taeniasis, and molluscum contagiosum diagnosed in Pap tests. Granuloma inguinale shows histiocytes that contain intracytoplasmic bacteria (Donovan bodies. Tuberculosis is characterized by necrotizing granulomatous inflammation with Langhans-multinucleated giant cells. Coccidioidomycosis may show large intact or ruptured fungal spherules associated with endospores. Schistosoma haematobium is diagnosed by finding characteristic ova with a terminal spine. Molluscum contagiosum is characterized by the appearance of squamous cells with molluscum bodies. This article reviews the cytomorphology of selected rare infections and focuses on their cytomorphology, differential diagnosis, and role of ancillary diagnostic studies.

    Full Text Available This study is a report on modifications and pilot testing of a measurement tool to predict Pap testing based on the Interaction Model of Client Health Behavior. Women have been found to avoid routine cervical cancer screening (CCS due to personal influencing factors. For this study, the Pap Smear Belief Questionnaire (PSBQ was modified by adding items and evaluated through content validity index (CVI = .89 and cognitive interviews (think-aloud protocol, resulting in a 31-item instrument with four subscales (Benefits, Barriers, Vulnerability, Experiences. Pilot testing the modified PSBQ was conducted at a local agency. Fifty-three women completed and returned the PSBQ, which had good internal consistency, with a Cronbach’s alpha coefficient of .81 (Benefits α = .51; Barriers α = .85; Vulnerability α = .78; Experiences α = .87. Test–retest reliability of the 31-item PSBQ was also good (.878. Univariate logistic regression indicated that the only significant predictor of seeking/avoiding routine screening by women’s background characteristics was social influence (p = .04. Subscales found to be significant predictors in Pap testing were Barriers (p = .003 and Gynecological Exam Experiences (p = .04. The refined 31-item PSBQ has good psychometric data supporting its use in predicting CCS. However, this research should be replicated in a larger sample enabling further validity and reliability testing of the PSBQ. Understanding women’s attitudes toward CCS will help health care providers, who deal with gynecological health, develop more effective screening programs and interventions facilitating better experiences for women contributing to an increase in routine screening.

    We sought to determine whether primary language use, measured by language of interview, is associated with disparities in cervical cancer screening. We undertook a secondary data analysis of a pooled sample of the 2001 and 2003 California Health Interview Surveys. The surveys were conducted in English, Spanish, Cantonese, Mandarin, Korean, and Vietnamese. The study was a cross-sectional analysis of 3-year Pap test use among women ages 18 to 64, with no reported cervical cancer diagnosis or hysterectomy (n = 38,931). In addition to language of interview, other factors studied included race/ethnicity, marital status, income, educational attainment, years lived in the United States, insurance status, usual source of care, smoking status, area of residence, and self-rated health status. We fit weighted multivariate logit models predicting 3-year Pap test use as a function of language of interview, adjusting for the effects of specified covariates. Compared with the referent English interview group, women who interviewed in Spanish were 1.65 times more likely to receive a Pap test in the past 3 years. In contrast, we observed a significantly reduced risk of screening among women who interviewed in Vietnamese (odds ratio [OR] 0.67; confidence interval [CI] 0.48-0.93), Cantonese (OR 0.44; 95% CI 0.30-0.66), Mandarin (OR 0.48; 95% CI 0.33-0.72), and Korean (OR 0.62; 0.40-0.98). Improved language access could reduce cancer screening disparities, especially in the Asian immigrant community.

    Full Text Available This paper describes the development and implementation of a Hmong Cervical Cancer Intervention Program utilizing a patient navigation model to raise cervical cancer awareness for Hmong women through educational workshops and to assist Hmong women in obtaining a Pap test. Out of 402 women who participated in a baseline survey, the Patient Navigation Program was able to enroll 109 participants who had not had a Pap test in the past 3 years and had never had a Pap test. Through utilization of outreach, an awareness campaign and patient navigation support, at least 38 percent of 109 participants obtained a Pap test. Overall, 21 workshops and 43 outreach activities were conducted by the Hmong Women’s Heritage Association, leading to 63 percent of those enrolled in the Patient Navigation Program who could be contacted to obtain a Pap test.

    Lack of medical care in North Korea and vulnerability to human trafficking during their migration increase risks of cervical cancer among North Korean refugees. To better understand factors influencing Pap test use, we conducted a qualitative study of eight North Korean refugees in South Korea. Individual barriers were limited knowledge, lack of perceived need for preventive services, and concerns about costs. Environmental facilitators included having female providers, receiving family support, and free screenings. Refugees' health outlook, including viewing cancers as fatal diseases, hindered seeking Pap tests. Multi-faceted approaches to address individual and environmental factors in promoting Pap tests are warranted.

    This study aimed to explore the factors associated with the intention to receive a Pap test among married immigrant women of Vietnamese origin living in Taiwan. This was a cross-sectional community-based study. We enrolled 281 women aged 30 years and over in the study, from July 2013 to January 2014. The participants' characteristics, cervical cancer knowledge, Pap test knowledge, attitudes toward cervical cancer, barriers to receiving a Pap test, fatalism, and intention to receive a Pap test, were measured using self-report questionnaires. Hierarchical multiple regression analyses were performed to examine the variables associated with participants' intentions to receive a Pap test. Vietnamese women with low scores on the measures of cervical cancer knowledge and perceived barriers to receiving a Pap test were more willing to receive the test, as were those with high scores on the measures of Pap test knowledge and fatalism. Women who received a Pap test in the previous year were more willing to receive a Pap test within the next 3 years. Preventive healthcare for immigrant women should be a focus of nurses. The development of culturally appropriate health education and strategies should enhance their knowledge of Pap tests and reduce perceived barriers to Pap test participation. This study's results can be a reference for nurses who work with immigrant women. Copyright © 2016. Published by Elsevier B.V.

    Understanding how individuals make decisions about Pap tests concerning their personal values helps health-care providers offer tailored approaches to guide patients' decision making. Yet research has largely ignored decision making about Pap tests among immigrant women who experience increased risk of cervical cancer. To explore decision making about Pap tests among Korean immigrant women. We conducted a qualitative descriptive study using 32 semi-structured, in-depth interviews with Korean immigrant women residing in a north-eastern metropolitan area. Data were audio-recorded, transcribed verbatim and analysed using inductive coding. Although most women with positive decisions made their own decisions, some women deferred to their providers, and others made decisions in collaboration with their providers and significant others. While women making positive decisions tended to consider both barriers to and facilitators of having Pap tests, women making negative decisions predominantly discussed the barriers to having Pap tests, such as modesty and differences between the South Korean and US health-care systems. The women's reflections on their decisions differed regarding their Pap test decisions. Women's desired roles in the decision-making process and reflection on their decision outcome appeared to vary, although most participants with positive decisions made their own decisions and were satisfied with their decisions. Future research should conduct longitudinal, quantitative studies to test our findings regarding decision-making processes and outcomes about Pap tests. The findings should be incorporated into cervical cancer screening practices to fulfil the unmet needs of immigrant women in patient-provider communication and to facilitate women's decision making about Pap tests. © 2016 The Authors.

    2016-02-01

    Data from 20 years ago--shortly after passage of the Americans with Disabilities Act--showed that women with significant mobility disability had 40% lower Pap test rates than other women. To examine whether disability disparities in Pap test rates have diminished over time, this study analyzed National Health Interview Survey responses from selected years between 1998 and 2010 from women aged 21-65 years without histories of cervical cancer or hysterectomy. Seven chronic disability types were identified using self-reported functional impairments or participation limitations. Self-reported Pap testing within the previous 3 years was studied. Bivariable analyses and multivariable logistic regression analyses controlling for sociodemographic variables were conducted in 2014. Rates of all chronic disability types increased over time. Pap test rates remained relatively constant over time for all women, holding around 84%-87%. Bivariable analyses found statistically significantly lower rates of Pap testing for women with disability compared with nondisabled women. Multivariable analyses failed to find consistent evidence of lower Pap test rates among women across disability types compared with nondisabled women. In 2010, the AOR for reporting Pap testing for women noting the most severe movement difficulty compared with nondisabled women was 0.35 (95% CI=0.15, 0.79). However, the AOR for this disability type varied over time. Little has changed over time in Pap test rates for all women. Women with certain disabilities continue to experience disparities compared with nondisabled women in receipt of this important screening test.

    Transmasculine (i.e., female-to-male transgender) individuals have lower rates of cervical cancer screening than nontransgender women and often report negative experiences with the Pap test. Deciding to undergo screening and the test experience itself are characterized by the following processes: negotiating identity as the patient, provider, and insurance company wrestle with the degree of (in)congruence between a patient's masculine gender identity and their conception of the Pap test as feminine; bargaining for health as a Pap test may be required to obtain medical transition services or avoid undesired health outcomes; withstanding acute challenges during the Pap test to body, identity, and privacy; or reframing challenges as affirmation. The degree of distress triggered by the Pap test varied from "routine" to traumatic. Participants affirmed that a trusted, trans-competent health care provider could significantly reduce barriers to regular and satisfactory cervical cancer screening. Data are from 32 in-depth interviews conducted in Boston, Massachusetts, with transmasculine individuals; a modified grounded theory approach informed the analysis.

    The purpose of this study was to develop and validate a questionnaire to examine women's beliefs about cervical cancer and the Pap test in Chilean women. The questionnaire, developed following the guidelines by Robert de Vellis, is based on the Health Belief Model. The content validity index was 0.93 upon review by 10 Chilean experts. A cross-sectional design was implemented to validate the questionnaire. The sample included 333 women recruited from a women's healthcare center in Santiago, Chile. Exploratory factor analysis was used to evaluate validity and coefficient α to evaluate reliability. After six models were computed, the questionnaire was reduced from 53 to 28 items. The new questionnaire, CPC-28 (in Spanish, Creencias, Papanicolaou, Cancer -28), includes six domains: the barriers domain to take a Pap test, the cues to action domain, the severity domain, the need to have a Pap test domain, the susceptibility to cervical cancer domain, and the benefit domain. The unexpected salient factor "need to have a Pap test" was found as part of the susceptibility domain proposed in the initial questionnaire. This finding is an important topic for future research. The CPC-28 questionnaire explained 49% of the total variance, and the reliability was .735. It was concluded that the CPC-28 questionnaire will have important implications on research, education, and administration across disciplines. Nursing curricula and healthcare providers must stress the importance and reinforce the importance of prevention of cervical cancer and regular Pap test screenings. © 2013 Sigma Theta Tau International.

    Full Text Available Background: Cervical cancer is known to be preventable because of long period of pre-invasive stage, availability of screening tools, and effective treatments for early invasive cervical lesions. Screening is main measures to prevent the disease and Pap smear is a screening strategy for cervical cancer. Current paper aimed to evaluate levels of awareness and practice regarding Pap smear screening among women aged between 20 to 65 years in Tehran (Iran. Methods: This was a descriptive-analytical study conducted in Tehran City of Iran in 2015 at Firoozgar Hospital. The research population included all married, widowed and divorced women aged 20-65 years. Data analysis was performed using the Pearson correlation and Student’s t-tests in SPSS, ver. 23 (Chicago, IL, USA. Results: Among 90 individuals who have fill questionnaire completely, 66.6% subjects had Pap smear tests. 40% of the individuals aged between 30 to 39 and the education level is distributed equally between Intermediate, Diploma and graduate and only 3 percent of them, continue their education to higher level. There was a significant relationship between the awareness of Pap smear and educational level (of both wives and husbands. The people who have graduate degree, have the best awareness. Working women revealed higher level of awareness about Pap smear. Shame and fear of taking the cancer were the most common reasons which lead to avoidance in doing the test by the women, while the most encouraging factors for performing the test were the information mostly provided by physicians and after that, the information provided by friends. Conclusion: The awareness of Pap smear test which was measured by weighting different questions in the questionnaire by experts, prove that the women aged above 39, have an average level of awareness of Pap smear test. Due to high prevalence of cervical cancer and prolonged pre invasive course, role of Pap smear for early diagnosis necessitate the use

    Microbial transformation of polyfluoroalkyl phosphate esters (PAPs) into perfluorocarboxylic acids (PFCAs) has recently been confirmed to occur in activated sludge and soil. However, there lacks quantitative information about the half-lives of the PAPs and their significance as the precursors to PFCAs. In the present study, the biotransformation of 6:2 and 8:2 diPAP in aerobic soil was investigated in semi-dynamics reactors using improved sample preparation methods. To develop an efficient extraction method for PAPs, six different extraction solvents were compared, and the phenomenon of solvent-enhanced hydrolysis was investigated. It was found that adding acetic acid could enhance the recoveries of the diPAPs and inhibit undesirable hydrolysis during solvent extraction of soil. However 6:2 and 8:2 monoPAPs, which are the first breakdown products from diPAPs, were found to be unstable in the six solvents tested and quickly hydrolyzed to form fluorotelomer alcohols. Therefore reliable measurement of the monoPAPs from a live soil was not achievable. The apparent DT_5_0 values of 6:2 diPAP and 8:2 diPAP biotransformation were estimated to be 12 and > 1000 days, respectively, using a double first-order in parallel model. At the end of incubation of day 112, the major degradation products of 6:2 diPAP were 5:3 fluorotelomer carboxylic acid (5:3 acid, 9.3% by mole), perfluoropentanoic acid (PFPeA, 6.4%) and perfluorohexanoic acid (PFHxA, 6.0%). The primary product of 8:2 diPAP was perfluorooctanoic acid (PFOA, 2.1%). The approximately linear relationship between the half-lives of eleven polyfluoroalkyl and perfluoroalkyl substances (PFASs, including 6:2 and 8:2 diPAPs) that biotransform in aerobic soils and their molecular weights suggested that the molecular weight is a good indicator of the general stability of low-molecular-weight PFAS-based compounds in aerobic soils. - Highlights: • Biotransformation of 6:2 and 8:2 diPAPs in an aerobic soil was investigated.

    Full Text Available Objective: The objective of the study is to evaluate the use of the Pap smear screening method for detection of precancerous lesions. Methods: All women who visited the outpatient gynecology clinic of the Department of Obstetrics and Gynaecology at King Georges Medical University, Lucknow, UP, India, over 1 year for different clinical problems were recruited for the study. A total of 1650 women who were sexually active and over 21 years of age were enrolled in the study. A clinical examination, an examination per speculum, and a vaginal examination were performed and a history taken for all women. A Pap smear was used for all women to screen for cervical cancer. The smear was obtained using an Ayre spatula and spread over a marked glass slide, which was placed in 95% ethyl alcohol and sent to the Department of Pathology for cytopathological examination. All data were recorded using a predetermined pro forma. Women who had visible malignant cervical lesions were excluded from the study. Results: Most women were in the age range of 30–50 years and multiparous. Vaginal discharge was the most common complaint, occurring in 36.96% of the women. An irregular menstrual cycle was the complaint of 12.78% and abdominal pain of 25.63% of women, while 15.15% were asymptomatic. The Pap smear test of 93.57% of the women was adequately taken, while 6.42% of the individuals had an inadequate sample. The test was negative for malignancy in 48.84%, and 42.66% had infection or inflammation. Atypical squamous cells of undetermined significance (ASCUS, low-grade squamous intraepithelial lesion (LSIL, and high-grade squamous intraepithelial lesion (HSIL were detected in 2.90%, 5.09%, and 0.48%, respectively. Women with Pap tests positive for ASCUS, LSIL, and HSIL underwent a colposcopy and guided biopsy. Conclusions: Women with an abnormal Pap test should undergo a colposcopy, and those with abnormal colposcopy findings should be advised to undergo a biopsy. A Pap

    Despite the established role of the Pap smear test (PST) in prevention and early detection of cervical cancer, it is still rarely practiced in Sudan. Many challenges hinder the establishment of an effective cervical cancer screening program, including socio-cultural factors. Therefore, this study aimed to investigate the knowledge, attitudes and practices (KAP) of Sudanese women with regard to the Pap smear test and cervical cancer. A total of 500 married women aged 14 to 58 years were recruited from obstetric clinics, hospitals and universities in Khartoum in 2014. Data were collected using a standardized, pretested questionnaire that inquired socio-demographic characteristics and their KAP about cervical cancer and the PST. More than 52% of participating women were above 30 years of age, and the majority (78.8%) were university degree holders. A total of 486 (97.2 %) of participants were resident in urban areas of Khartoum State. However about 48% of the respondents had never heard about PST, and only 15.8% of the participants had undergone a Pap smear test previously; 46.6% (233/500) knew that the human papilloma virus (HPV) was the causative agent, but only 39.2% (196/500) had heard about HPV vaccination, and only 11.4% (57/500) had received the vaccine. However 68% of the respondents agreed to do Pap smear if properly informed about the test and 75.4% of the respondents agreed to participate in a cervical cancer screening program. Despite a high educational level, less than half of our participants had accurate knowledge about cervical cancer, HPV, and cervical cancer screening. Health education about cervical cancer, HPV and sexually transmitted infections and the role of PST in cervical cancer prevention are crucial when designing interventions aimed at improving cervical cancer screening for Sudanese women.

    Describe the association between receipt of cervical cytology and type of health insurance in Peruvian women, and determine the role of sociodemographic and sexual health variables in this relationship. A cross-sectional study using information on a sample of 12 272 women aged 30 to 49 years from the Demographic and Family Health Survey (ENDES), Peru, 2005-2008. The dependent variable was receipt of at least one Pap smear in the last five years. The primary independent variables were type of health insurance, educational level, household socioeconomic level, ethnicity, and place of residence. Prevalence ratio, obtained from Poisson regression with robust variance, was used to measure multivariate association. Among sexually active women, 62.7% had received at least one Pap test in the last five years. Percentage of women tested varied by type of health insurance. Women with public or private insurance had a greater probability of having received a Pap smear--1.27 (95% CI, 1.24-1.31) and 1.52 (95% CI, 1.46-1.58) times greater, respectively--than uninsured women. This association was primarily explained by socioeconomic status variables. In addition, women who participated the least in screening were characterized by illiteracy or only a primary education, low socioeconomic level, speaking an indigenous language, and living in a rural area. When they also lacked health insurance, the gap widened, rising to as much as one third compared to more advantaged social groups. Inequalities were found in receipt of Pap testing according to type of health insurance; women without insurance were least likely to be screened, implying existence of a barrier to cervical cancer screening in Peru.

    This study explored narrative responses following abnormal Pap tests among Hispanic migrant farmworkers ( N = 18; ages 22-50 years) via in-depth interviews in Florida. Qualitative analyses utilized health literacy domains (obtain/process/understand/communicate) as a conceptual framework. Participants described how they (1) obtained information about getting a Pap test, (2) processed positive and negative reactions following results, (3) understood results and recommended health-promoting behaviors, and (4) communicated and received social support. Women had disparate reactions and understanding following an abnormal Pap result. Health literacy was a meaningful conceptual framework to understand assets and gaps among women receiving an abnormal Pap test result. Future interventions should incorporate health literacy domains and facilitate patient-provider communications and social support to assist women in decision-making and health-promoting behaviors, ultimately decreasing cancer disparities.

    The frequently cited number of 50 million annual Papanicolaou cervical screening (Pap) tests performed in the US was based on the National Health Interview Survey (NHIS) of the 1980s. Since then, monumental changes have occurred. More change will soon follow when primary human papilloma virus (HPV) testing and/or HPV vaccine delivery are fully accepted and implemented. The objectives of this study were 1) to estimate the total annual Pap tests performed in the US based on recent NHIS surveys, and 2) to estimate the potential change in the total annual Pap volume produced by changing demographics, reduced screening frequency, HPV testing, and the HPV vaccine. In the NHIS 2000 and NHIS 2005, women were asked to report the frequency of their Pap tests for the 6 years prior to the interview and to report whether they had abnormal findings. The authors analyzed the survey respondents answers to these questions by using SAS Survey Procedures (SAS Institute, NC). The results were stratified by age, and the total national volume was then extrapolated from a similarly stratified 2000 US census. The projected increase of total Pap tests for the next 25 years was determined by using the projected census data. Potential reductions of Pap tests performed secondarily to HPV testing of women >30 years old and of HPV vaccination were also determined. Based on NHIS 2000 and NHIS 2005, 66 million (95% CI, 65-68) and 65 million (95% CI, 64-67) Pap tests were performed in the US, respectively. Had HPV testing been performed in women older than 30 years who had both negative HPV and negative 3-year Pap tests, then 30% (95% CI, 29-32%) of Pap tests would not have been performed. If both HPV testing and vaccination are performed, the total number of Pap tests performed annually is predicted to be reduced by 43% (95% CI, 35-38%). Therefore, despite an expected increase in the population of women eligible for Pap tests, the total number will likely decrease substantially in the future

    The present study was designed to ascertain knowledge about HPV, cervical cancer (CC) and the Pap test among female dental students of Panineeya Institute of Dental Sciences and Hospital, Hyderabad, India. A self-administered questionnaire covering demographic details, knowledge relating to human papilloma virus (HPV) (8 items), cervical cancer (4 items) and the Pap smear (6 items) was employed. Responses were coded as "True, False and Don't Know". Mean and standard deviation (SD) for correct answers and levels of knowledge were determined. Based on the year of study, significant differences in knowledge of HPV were noted for questions on symptoms (p=0.01); transmission from asymptomatic partners (p=0.002); treatment with antibiotics (p=0.002); start of sexual activity (p=0.004); and recommended age for HPV vaccination (p=0.01). For knowledge regarding CC, significance was observed for the age group being affected (p=0.008) and symptoms of the disease in early stages (p=0.001). Indications for Pap smear tests like symptoms' of vaginal discharge (p=0.002), marital status (p=0.01) and women with children (p=0.02) had significant difference based on the year of study. Based on religion, transmission of HPV via pregnancy, HPV related diseases except CC and preventive measures except condom use and oral contraceptives showed significant differences. However, significant variation with religion was observed only for two preventive measures of CC (Pap test; p=0.004) and HPV vaccination (p=0.003). Likewise, only the frequency of Pap test showed a significant difference for religion (p=0.001). This study emphasizes the lack of awareness with regard to HPV, CC and screening with pap smear even among health professionals. Hence, regular health campaigns are essential to reduce the disease burden.

    Full Text Available Little is known about the factors influencing screening among low-income Hispanic women particularly among recent immigrants. A sample of 148 low-income, low-literate, foreign-born Hispanic women residing in the Washington DC metropolitan area participated in the study. The mean age of the sample was 46.2 (SD = 11.5, 84% reported annual household incomes<=$15,000. All women were Spanish speakers and had low acculturation levels. Ninety six percent had reported having a Pap smear, but 24% were not in compliance with recommended screening (Pap test within the last 3 years. Among women 40 and older, 62% had received a mammogram, but only 33% were compliant with age appropriate recommended mammography screening guidelines. Women in this study had more misconceptions about cancer than Hispanics in other studies. Multivariate logistic models for correlates of Pap test and mammography screening behavior indicate that factors such as fear of the screening test, embarrassment, and lack of knowledge influenced screening behavior. In conclusion, women in this study had lower rates of mammography screening than non-Hispanic women and lower rates of compliance with recommended Mammography and Pap test screening guidelines.

    Full Text Available Background: Cervical cancer is a preventable disease with a regular screening program. Many studies have reported a large number of barriers that women had for the first time, but this study decided to find other barriers for the second time pap smear. Methods: In this qualitative research, data were gathered through in-depth interviews and expressed through conventional content analysis in the form of constant comparison. The participants were 15 women with family profile at 30 health care centers who lived in the south of Tehran and had done Pap smear for one time but didn’t do it for the second time. Results: Three main themes emerged from the analysis of the interviews: negative experiences of the first Pap test were as follows: results of the first time test, readiness for performing the test, getting the test itself, and the site of the first Pap test. Personal barriers to getting the second Pap test were: inattention to time, physical barriers to the second Pap test, and inhibitory beliefs. Perceived social barriers to getting the second Pap test with two sub-themes included social supports and abstract norms. Conclusion: This study provided other barriers about Pap smear including lack of the spouse’s support, the role of health care providers and physicians in screening program for early diagnosis in women.

    We sought to test the diagnostic efficacy of a low-cost, liquid-based cervical cytology that could be implemented in low-resource settings. A prospective, split-sample Pap study was performed in 595 women attending a cervical cancer screening clinic in rural El Salvador. Collected cervical samples were used to make a conventional Pap (cell sample directly to glass slide), whereas residual material was used to make the liquid-based sample using the ClearPrep method. Selected samples were tested from the residual sample of the liquid-based collection for the presence of high-risk Human papillomaviruses. Of 595 patients, 570 were interpreted with the same diagnosis between the 2 methods (95.8% agreement). There were comparable numbers of unsatisfactory cases; however, ClearPrep significantly increased detection of low-grade squamous intraepithelial lesions and decreased the diagnoses of atypical squamous cells of undetermined significance. ClearPrep identified an equivalent number of high-grade squamous intraepithelial lesion cases as the conventional Pap. High-risk human papillomavirus was identified in all cases of high-grade squamous intraepithelial lesion, adenocarcinoma in situ, and cancer as well as in 78% of low-grade squamous intraepithelial lesions out of the residual fluid of the ClearPrep vials. The low-cost ClearPrep Pap test demonstrated equivalent detection of squamous intraepithelial lesions when compared with the conventional Pap smear and demonstrated the potential for ancillary molecular testing. The test seems a viable option for implementation in low-resource settings.

    Full Text Available Background: Studies for liquid-based Papanicolaou (Pap tests reveal that liquid-based cytology (LBC is a safe and effective alternative to the conventional Pap smear. Although there is research on ThinPrep and SurePath systems, information is lacking to evaluate the efficiency and effectiveness of systems based on cytocentrifugation. This study is designed to determine the sensitivity and specificity of the Shandon PapSpin (ThermoShandon, Pittsburgh, Pennsylvania, USA liquid-based gynecological system. We used split-sample and direct-to-vial study design. Materials and Methods: 2,945 women referred to prophylactic check-up were enrolled in this study. Split sample design was used in 1,500 women and residual cervical cytology specimen from all these cases was placed in fluid for PapSpin preparation after performing conventional smear. The direct-to-vial study was carried out in another cohort of 1,445 women in whom the entire cervical material was investigated using only the PapSpin technique. Follow up histological diagnoses for 141 women were obtained from both study arms following 189 abnormal cytology cases. 80 LBC cases from the split sample group and 61 LBC cases in the direct-to-vial group were correlated with the histology results. The sensitivity and secificity of the conventional smear and PapSpin tests in both study arms were compared. Results: In the split sample group, conventional smears showed a higher proportion of ASC-US (atypical cells undetermined significance: 31 (2.1% vs 10 (0.7% in PapSpin (P = 0.001. A higher proportion of unsatisfactory samples was found in the conventional smear group: 25 (1.7% vs 6 (0.4% cases (P = 0.001. In the split sample group, the sensitivity of the conventional and PapSpin tests was 68.7% vs 78.1%, and the specificity 93.8% vs 91.8%, respectively. In the direct to vial group PapSpin sensitivity was 75.9% and specificity 96.5%. The differences in sensitivity and specificity were not significant. The

    Full Text Available Abstract Background The cytological screening programme of Viterbo has completed the second round of invitations to the entire target population (age 25–64. From a public health perspective, it is important to know the Pap-test coverage rate and the use of opportunistic screening. The most commonly used study design is the survey, but the validity of self-reports and the assumptions made about non respondents are often questioned. Methods From the target population, 940 women were sampled, and responded to a telephone interview about Pap-test utilisation. The answers were compared with the screening program registry; comparing the dates of Pap-tests reported by both sources. Sensitivity analyses were performed for coverage over a 36-month period, according to various assumptions regarding non respondents. Results The response rate was 68%. The coverage over 36 months was 86.4% if we assume that non respondents had the same coverage as respondents, 66% if we assume they were not covered at all, and 74.6% if we adjust for screening compliance in the non respondents. The sensitivity and specificity of the question, "have you ever had a Pap test with the screening programme" were 84.5% and 82.2% respectively. The test dates reported in the interview tended to be more recent than those reported in the registry, but 68% were within 12 months of each other. Conclusion Surveys are useful tools to understand the effectiveness of a screening programme and women's self-report was sufficiently reliable in our setting, but the coverage estimates were strongly influenced by the assumptions we made regarding non respondents.

Method a cross-sectional study, carried out with 775 patients who underwent the Pap smear test in the Centro de Saúde da Família of Fortaleza, between September 2010 and February 2011. Results the majority of the women studied were young (≤35 years), had low levels of education (≤7 years of study), and commenced sexual activity early (≤20 years), with 17.0% of them failing to return to receive the test results. Statistically significant results for the failure to return were related to: young women (p=0.001); early onset of sexual activity (p=0.047); and inadequate knowledge about the Pap smear test (p=0.029). Conclusion the fact that the women failed to return for the result is a problem for the control of cervical cancer and must be addressed through educational strategies that reinforce the importance of the return for the early detection of this cancer.

    The purpose of this study was to determine and compare the knowledge and attitudes toward human papillomavirus (HPV), HPV vaccine, Pap tests, and cervical cancer among US and Peruvian women. A convenience sample of 275 US women in Augusta, GA, and 702 Peruvian women living in or near Cusco, Peru, completed 22- or 21-item questionnaires, respectively. These questionnaires determined their knowledge about HPV, the HPV vaccine, Pap tests, and cervical cancer. Simple logistic regression was used to determine the relationship between location and language on the correct responses. Odds ratios (ORs) and 95% confidence intervals were calculated. US Spanish- (OR = 0.02), Quechua- (OR = 0.05), and Peru Spanish-speaking women (OR = 0.03) were significantly less likely to know that HPV causes cervical cancer compared with US non-Spanish-speaking women. US Spanish- (OR = 10.61, OR = 5.74), Quechua- (OR = 11.08, OR = 9.89), and Peru Spanish-speaking women (OR = 17.25, 14.43) were significantly more likely to be embarrassed and afraid, respectively, to get a Pap test compared with US non-Spanish-speaking women. US Spanish- (OR = 0.11), Quechua- (OR = 0.14), and Peru Spanish-speaking women (OR = 0.11) women were significantly less likely to know the HPV vaccine is safe and effective compared with US non-Spanish-speaking women. Education must be implemented to address serious misconceptions and worrisome attitudes toward Pap tests and the HPV vaccine to decrease the rate of cervical cancer in Peru and US Spanish-speaking women.

    Cervical cancer is the most common female genital tract carcinoma worldwide. It is increasingly becoming the leading carcinoma seen among women in the developing world. The aim of our study was to showcase the effect of educational intervention on the knowledge of cervical cancer and subsequently the uptake of Pap smear test amongst market women in Niger state, Nigeria. The state has a rich network of markets in all the local government areas because of the fishing activities, bountiful agricultural produce yearly and its situation to the North of the national capital, Abuja. This was a quasi-experimental study conducted in two groups with pre and post intervention data collection. Sample size was determined based on a previous similar study done in Nigeria. Multi stage sampling technique was used for recruiting the study participants. SPSS statistical software was used for data entry, editing and analysis. Respondents' knowledge of cervical cancer were comparable at pre-intervention but were statistically significantly better (P<0.0001) at post-intervention in the intervention group compared to the control group for every variable measured. However, there was only a (Fisher's exact, P=0.621) compared to the control group. This study showed an increase in knowledge about cervical cancer and Pap smear test however the uptake of Pap smear test remained low even after intervention. This underscores the need for sustained intervention programs to eventually translate knowledge acquired to habitual practice.

    To estimate the association between the human papillomavirus (HPV) vaccine and sexual risk behaviour, as well as the participation in the Cervical Cancer Screening Program (CCSP). Cross-sectional study. School of Medicine and Health Sciences, School of Law, and School of Economics and Business (University of Oviedo). Female university students. Information was collected about contraceptive methods, sexual behaviours, HPV knowledge, and participation in the CCSP. Furthermore, proportions and odds ratio (OR) were estimated with their corresponding 95% confidence intervals (95%CI). Approximately two-thirds (67.7%) of the sample was vaccinated against HPV, and 216 women (65.3%) were sexually active. Barrier contraceptive methods were used by 67.6% during their current intimate relationships, being less frequent in non-vaccinated women (54.9% vs. 75.4% in vaccinated female students) (P=.002). The risk of having at least one sexual risk behaviour was higher in non-vaccinated women: OR2.29 (95%CI: 1.29-4.07). In addition, the probability of having a PAP test within the CCSP was higher in non-vaccinated women: OR2.18 (95%CI: 1.07-4.47). The prevalence of sexual risk behaviours in non-vaccinated women is elevated, and it is related to the lack of use of barrier contraceptive methods. The vaccination against HPV could affect sexual behaviours and the participation in the CCSP. Therefore, the information received by young people about contraceptive methods, sexually transmitted diseases, and cancer prevention should be reinforced. Copyright © 2017 Elsevier España, S.L.U.

    Our objective was to evaluate the progression and regression of cervical dysplasia in human immunodeficiency virus (HIV)-positive women during the late antiretroviral era. Risk factors as well as outcomes after treatment of cancerous or precancerous lesions were examined. This is a longitudinal retrospective review of cervical Pap tests performed on HIV-infected women with an intact cervix between 2004 and 2011. Subjects needed over two Pap tests for at least 2 years of follow-up. Progression was defined as those who developed a squamous intraepithelial lesion (SIL), atypical glandular cells (AGC), had low-grade SIL (LSIL) followed by atypical squamous cells-cannot exclude high-grade SIL (ASC-H) or high-grade SIL (HSIL), or cancer. Regression was defined as an initial SIL with two or more subsequent normal Pap tests. Persistence was defined as having an SIL without progression or regression. High-risk human papillomavirus (HPV) testing started in 2006 on atypical squamous cells of undetermined significance (ASCUS) Pap tests. AGC at enrollment were excluded from progression analysis. Of 1,445 screened, 383 patients had over two Pap tests for a 2-year period. Of those, 309 had an intact cervix. The median age was 40 years and CD4+ cell count was 277 cells/mL. Four had AGC at enrollment. A quarter had persistently normal Pap tests, 64 (31%) regressed, and 50 (24%) progressed. Four developed cancer. The only risk factor associated with progression was CD4 count. In those with treated lesions, 24 (59%) had negative Pap tests at the end of follow-up. More studies are needed to evaluate follow-up strategies of LSIL patients, potentially combined with HPV testing. Guidelines for HIV-seropositive women who are in care, have improved CD4, and have persistently negative Pap tests could likely lengthen the follow-up interval.

    Full Text Available Abstract Background Mothers have a primary role in the prevention of cervical cancer in Korea. This study aimed to determine the awareness and health beliefs of mothers about preventing cervical cancer in their daughters, their intention to recommend the Pap test to their daughters, and the factors influencing this intention. Methods A cross-sectional survey design was employed, and the study enrolled mothers (n = 1,581 of pubescent girls aged 13 to 18 years who were living nationwide in Korea. The six health-beliefs variables related to preventing cervical cancer in their daughters, awareness of the importance of cervical cancer prevention methods, and the intention to recommend the Pap test to daughters were investigated. The impacts of these health beliefs of the mothers and the sociodemographic factors influencing their intention to recommend the Pap test to their daughters were assessed using multiple logistic regression analysis. Results Almost one-quarter (23.7 % of the mothers had talked about the Pap test, 69.2 % were intending to recommend the Pap test to their daughters, and 38.5 % considered that the Pap test could be necessary if their daughters became sexually active. The significant health beliefs influencing the intention to recommend the Pap test were the perceived barriers [odds ratio (OR = 1.47, 95 % confidence interval (95 % CI = 1.03–2.11] and benefits (OR = 2.25, 95 % CI = 1.55–3.25. The significant sociodemographic factors of mothers were their education (OR = 1.52, 95 % CI = 1.08–2.13, their experience of talking about the Pap test with their daughters (OR = 2.11, 95 % CI = 1.23–3.64, their regularity of undergoing the Pap test themselves (OR = 1.98, 95 % CI = 1.30–3.03, and their age when they first underwent the Pap test (OR = 1.60, 95 % CI = 1.43–0.82. Conclusions The mothers perceived HPV vaccination as the most important of the five methods

    Objective: To determine the frequency of Pap smear testing among women and to evaluate their level of knowledge about the test and other relevant factors. Methods: The study comprised women who presented to the Gynaecology and Obstetrics Polyclinic of Sakarya Training and Research Hospital, Turkey, between April 1 and 30, 2012. The questionnaire was developed in line with the objectives of the study. They were filled by the participants who were supervised during the process. Women who had had at least one Pap smear test in life were considered to have taken a Pap smear test , and those who had heard of the test were accepted as women who k new of the Pap smear test . Data was analysed using SPSS 15.0. Chi-square test was used for analyses, and statistical significance was set at p<0.05. Results: The age of 601 subjects ranged between 15 and 64 years, with a mean of 31.09+-10.49 years. Of the total, 115 (19.1%) had taken a Pap smear test before and 293 (48.8%) knew of the test. The proportion of the women who had had a Pap smear test was higher among those who were over 30 years of age (n=73; 63.47%), had post-high school educational degrees (n=68; 59.13%), had moderate familial income status (n=74; 64.34%), were married (n=109; 94.78%), had first sexual experience after 25 years of age(n=42; 36.52%), and were not using a contraceptive method (n=97; 84.34%) (p<0.05 for each). Besides, more women with previous knowledge of the test had taken the test (p<0.05). Conclusion: The subjects did not have sufficient information on Pap smear and the frequency of having a test was low. Raising awareness would prove beneficial. (author)

    Discussion: The study reveals HPV prevalence rate of 28.3% in women attending gynaecology OPD of a tertiary care hospital and also prevalence of HPV was found to be highest in sexually active individuals with parity of 3 or more. These results are in agreement to many published national and international studies [12,13,14]. The study results also indicate lower sensitivity and higher specificity of Pap smear in detecting HPV infection, however it still remains the most important practicably available test in early detection of cervical carcinoma.

    To study women's knowledge regarding the role of human papilloma virus (HPV) in cervical intraepithelial neoplasia and their attitudes toward the integration of HPV testing as part of routine follow-up of atypical squamous cell of uncertain significance/low-grade squamous intraepithelial lesion (ASCUS/LGSIL) abnormalities. Over a 12-month period, all women attending the University of Ottawa colposcopy clinic for evaluation and follow-up of ASCUS/LGSIL Pap smears were recruited. Demographic data included age, nature of the Pap smear abnormality, gravidity, parity, occupation and education level, smoking history, previous history of abnormal smears, colposcopic examination and treatment, and current method of contraception. The women were asked to rate their level of concern over their Pap smear abnormality, from 0 (not concerned) to 10 (very concerned). Women's knowledge regarding the role of HPV in cervical intraepithelial neoplasia and the rationale behind the use of HPV testing was assessed by the clinic nurse as being minimal, moderate, or good, as defined by pre-specified criteria. Upon explanation by the nurses of the results of the recent ALTS (ASCUS/LGSIL Triage Study) trial, the women were asked to state whether they preferred to continue with regular colposcopic surveillance every 6 months, or to use the results of the HPV test, if negative, to reduce the number of colposcopy examinations to one annually. Descriptive statistics and logistic regression analysis were used to identify significant demographic factors associated with the women's preference for incorporation of HPV testing in their follow-up. All P values less than.10 were considered to be statistically significant, due to the exploratory nature of the study. Of the 100 women who participated in the study, 42% presented with ASCUS.

    Few Iranian women take the Papanicolaou test despite its important role in preventing cervical cancer. This study aimed to determine the effectiveness of an educational intervention based on the protection motivation theory (PMT) variables and implementation intentions in the first and second Pap test practice among Iranian women. In this quasi-randomized controlled trial, 200 women who were referred to 30 primary health care clinics in Tehran were randomly selected. PMT variables and Pap test practice were measured at baseline and again after 3 and 15 months. The 4-week educational intervention program was conducted for the intervention group. Following the intervention, the mean scores of self-efficacy, perceived vulnerability, and behavior intention variables were significantly higher in the intervention group when compared to the control group (ptheory-based framework for developing educational interventions regarding Pap test practice in Iran.

    Given that there are many Iranian women who have never had a Pap smear, this study was designed to develop and validate a measurement tool based on the Protection Motivation Theory to assess factors influencing the Iranian women's intention to perform first Pap testing. In this psychometric research, to determine the Content Validity Index (CVI) and the Content Validity Ratio (CVR), a panel of experts (n=10) reviewed scale items. Reliability was estimated through the Intraclass Correlation Coefficient (n=30) and internal consistency (n=240). Also, factor analysis (exploratory and conformity) was performed on the data of the sample women who had never had a Pap smear test (n=240). A 26-item questionnaire was developed. The CVI and CVR scores of the scale were 0.89 and 0.90, respectively. Exploratory factor analysis loaded a 26-item with seven factors questionnaire (perceived vulnerability and severity, fear, response costs, response efficacy, self-efficacy, and protection motivation (or intention)) that jointly accounted for 72.76% of the observed variance. Confirmatory factor analysis indicated a good fit for the data. Internal consistency (range 0.70-0.93) and test-retest reliability (range 0.72-0.96) of sub-scales were acceptable. This study showed that the designed instrument was a valid and reliable tool for measuring the factors influencing the women's intention to perform their first Pap testing.

    Cervical cancer is known as one of the most prevalent types of cancers and a major public health problem in developing countries which can be detected by Pap test, prevented, and treated. Despite the effective role of Pap test in decreasing the incidence and mortality due to cervical cancer, it is still one the most common causes of cancer-related deaths among women, especially in developing countries. Thus, this study aimed to examine the effect of educational interventions implemented by health volunteers based on protection motivation theory (PMT) on promoting Pap test use among women. This quasi-experimental study was conducted on 60 health volunteers and 420 women. The study participants were divided into an intervention and a control group. Data were collected using a valid self-reported questionnaire including demographic variables and PMT constructs which was completed by both groups before and 2 months after the intervention. Then, the data were entered into the SPSS statistical software, version 19 and were analyzed using Chi-square test, independent T-test, and descriptive statistical methods. P<0.05 was considered as statistically significant. The findings of this study showed that the mean scores of PMT constructs (i.e. perceived vulnerability, perceived severity, fear, response-costs, self-efficacy, and intention) increased in the intervention group after the intervention (P<0.001). However, no significant difference was found between the two groups regarding response efficacy after the intervention (P=0.06). The rate of Pap test use also increased by about 62.9% among the study women. This study showed a significant positive relationship between PMT-based training and Pap test use. The results also revealed the successful contribution of health volunteers to training cervical cancer screening. Thus, training interventions based on PMT are suggested to be designed and implemented and health volunteers are recommended to be employed for educational

    Trans-masculine (TM, i.e., persons who have a masculine spectrum gender identity, but were assigned female sex at birth) individuals face disparities in cervical cancer screening rates compared to cisgender women. Some unique barriers to screening in this population are specific to Pap tests. Introduction of self-collected frontal (i.e., vaginal) swabs for human papillomavirus (HPV) testing as a screening strategy may obviate these barriers. This study elucidates cervical cancer screening preferences among TM individuals. TM individuals participated in in-depth interviews (n = 31) and online surveys (n = 32) to explore perceptions and experiences regarding cervical cancer screening, including the acceptability of self-collected frontal HPV swabs for cervical cancer screening compared to provider-administered Pap tests. Provider-collected frontal HPV swab acceptability was also explored. Most TM individuals (94% in-person and 91% online participants) preferred either the self- or provider-collected frontal HPV swab to the Pap test. Participants perceived self- and provider-collected frontal HPV swabs to be less invasive, provoke less gender discordance, and promote a greater sense of agency compared to Pap tests. However, some participants expressed concern about HPV swab accuracy and, regarding the self-collected swab, discomfort about the need to engage with genitals they may not want to acknowledge. Individuals who reported positive provider relationships found Pap tests and provider-collected frontal swabs more acceptable than those who did not. Frontal HPV swabs have the potential to promote regular cervical cancer screening among TM individuals and to narrow screening disparities. Work is ongoing to establish swab accuracy and develop shared decision-making tools.

    Objective The objective of this study was to determine the attitudes and acceptability of self-administered cervicovaginal sampling compared with conventional physician-acquired Papanicolaou (Pap) smear among multiethnic Malaysian women. Method A cross-sectional study was carried out via interviewer-administered surveys from August 2013 through August 2015 at five government-run, urban health clinics in the state of Selangor. Subjects were participants from an ongoing community-based human papillomavirus (HPV) prevalence study who answered a standard questionnaire before and after self-sampling. The cervicovaginal self-sampling for HPV genotyping was performed using a simple brush (‘Just for Me’; Preventive Oncology International, Hong Kong). Detailed data on sociodemographics, previous Pap smear experience, and attitudes towards self-administered cervicovaginal sampling were collected and analysed. Acceptability was inferred using a five-item Likert scale that included six different subjective descriptives: experience, difficulty, convenience, embarrassment, discomfort or pain, and confidence in collecting one's own sample. Results Of the 839 participants, 47.9% were Malays, followed by 30.8% Indians, 18.8% Chinese and 2.5% from other ethnicities. The median age of the participants was 38 years (IQR 30–48). Some 68.2% of participants indicated a preference for self-sampling over the Pap test, with 95% indicating willingness to follow-up a positive result at the hospital. Age, ethnicity and previous Pap test experience were significant independent factors associated with preference for self-sampling. The older the individual, the less likely they were to prefer self-sampling (adjusted OR 0.94, 95% CI 0.90 to 0.98). The Chinese were less likely to prefer self-sampling (72.6%) than the Malays (85.1%) (adjusted OR 0.57, 95% CI 0.33 to 0.98, p=0.004). Participants who had never undergone a Pap smear were also more likely to prefer self-sampling (88.5%) than

    Proline aminopeptidase (PAP, EC 3.4.11.5) is the only enzyme that effectively releases proline from the N-termini of peptides. The amino acid sequence of the PAP from Triticosecale, TsPAP1, comprises conserved regions, characteristic of the monomeric forms of PAP found in bacteria but not yet identified in plants. Therefore, we aimed to obtain and biochemically characterize the TsPAP1 protein. The recombinant TsPAP1 protein was received through heterologous expression of the TsPAP1 coding sequence in a bacterial expression system and purified with affinity chromatography. Gel filtration chromatography and SDS electrophoresis revealed that TsPAP1 is a monomer with a molecular mass of 37.5 kDa. TsPAP1 prefers substrates with proline at the N-terminus but is also capable of hydrolyzing β-naphthylamides of hydroxyproline and alanine. Among the peptides tested, the most preferred were di- and tripeptides, especially those with glycine in the Y position. The use of diagnostic inhibitors indicated that TsPAP1 is a serine peptidase; however, further characterization revealed that the SH residues are also important for maintaining its activity. To examine the role of TsPAP1 under physiological conditions, we developed transgenic Arabidopsis plants overexpressing TsPAP1. Compared with wild-type plants, the transgenic lines accumulated more proline, flowered an average of 3.5 days earlier, and developed more siliques than did untransformed controls. Our paper is the first to describe the biochemical properties of a novel monomeric plant PAP and contributes to the functional characterization of PAP proteins in plants.

    P fimbrial adhesins may be associated with the virulence of avian pathogenic Escherichia coli (APEC). However, most APECs are unable to express P fimbriae even when they are grown under conditions that favor P fimbrial expression. This failure can be explained by the complete absence of the pap operon or the presence of an incomplete pap operon in Pap-negative APEC strains. In the present study, we analyzed the pap operon, specifically the papA gene that encodes the major fimbrial shaft, to better understand the pap gene cluster at the genetic level. First, by PCR, we examined a collection of 500 APEC strains for the presence of 11 genes comprising the pap operon. Except for papA, all the other genes of the operon were present in 38% to 41.2% of APEC, whereas the papA was present only in 10.4% of the APEC tested. Using multiplex PCR to probe for allelic variants of papA, we sought to determine if the low prevalence of papA among APEC was related to genetic heterogeneity of the gene itself. It was determined that the papA of APEC always belongs to the F11 allelic variant. Finally, we sequenced the 'papA region' from two papA-negative strains, both of which contain all the other genes of the pap operon. Interestingly, both strains had an 11,104-bp contig interruptingpapA at the 281-bp position. This contig harbored a streptomycin resistance gene and a classic Tn10 transposon containing the genes that confer tetracycline resistance. However, we noted that the papA gene of every papA-negative APEC strain was not interrupted by an 11,104-bp contig. It is likely that transposons bearing antibiotic resistance genes have inserted within pap gene cluster of some APEC strains, and such genetic events may have been selected for by antibiotic use.

    The research presents different configurations of microfluidic mixers made from polydimethylsiloxane (PDMS) fabricated using an improved, low-cost print-and-peel (PAP) method. Processes, such as mixing, operated in the micro scale allow decreased equipment size-to-production capacity ratio and decreased energy consumption per unit product. In the study, saturated solutions of blue and yellow food dyes were introduced inside the channels using a LEGO® improvised microsyringe pump. Scanning Electron Microscopy (SEM) was used to determine the average depth of the fabricated micromixers which was found to be around 14 ¼m. The flows were observed and images were taken using a light microscope. The color intensities of the images were then measured using MATLAB®. From the relationship between color intensity and concentration, the mixing indices were calculated and found to be 0.9435 to 0.9941, which falls within the standard mixing index range (0.8 - 1.0) regardless of the flow rate and the configuration of the micromixer as verified through the two-way ANOVA. From the cost analysis, the cost of the device fabricated in this study is a hundred-fold less than expenses from standard fabrication procedures. Hence, the fabricated device provides an alternative for micromixers produced from expensive and conventional lithographic methods.

    The non-participation to cervical screening is the major determinant in the risk of mortality due to cervical cancer. In France, around 40% of women do not participate to regular screening. The cultural or economic barriers for performing screening by Pap test are numerous; one of the most frequent is the refusal of gynaecological examination. A persistent HPV(HR) infection is a necessary factor for developing cervical cancer. The HPV(HR) testing has a high sensibility to detect high grade cervical intra-epithelial neoplasia (CIN 2-3) and a satisfactory specificity after 30-35 years old. The principal objective of this study was to compare the participation rates in women 35-69 years old who did not perform a Pap test after a first individual invitation, either when an HPV(HR) auto-test was offered to be performed at home or a second invitation to Pap test was sent. We also evaluated the quality of the two tests, the positive results obtained by age groups and the following histological type of lesions diagnosed in the women with positive results. The study included 9,334 women, 35-69 years old, who did not realized a Pap-test during the 2 previous years and who did not respond at a first individual invitation. These non-responders were randomized into two groups: one group (n=4,934) received a second individual invitation and the other (n=4,400) an offer of receiving and performing an HPV auto-test at home. In women 35-69 years the participation to the second invitation to Pap test was significantly lower (7.2%) than the participation to auto-test (26.4%) with Plaw rate is a consequence of an inversion of the ratio HPV 16 versus other types in women 60 years old and over. In this group, the follow-up of 36 women diagnosed five cases of CIN1, one of CIN2 and four of CIN3; 22 patients are lost of follow up at 6 months. Globally, in the studied population, an individual recall for pap test allowed to diagnose and treat 3 high grade lesions (7‰) and the dispatching

    Full Text Available Abstract Background and Objectives: Escherichia coli is the most common etiologic factor of urinary tract infection, which its most important virulence factor is P fimbriae. Uropathogenic E. coli expresses various types of adhesins, such as pili adhesins (pyelonephritis-associated pili, Pap that mediates binding to the surface of epithelial cells of the urinary tract. This study aims to identify papC and papG genes and to evaluate antibiotic resistance level in the isolated E. coli samples. Methods: In this descriptive cross-sectional study, 50 samples were collected from patients with urinary tract infection and after isolation of bacteria and DNA extraction, antibiotic susceptibility tests was performed by disc diffusion method using related antibiotics. Presence of papG and papC genes (class I, II, and III was assessed by multiplex PCR method. Statistical data were analyzed using descriptive t-test. Results: The isolated E. coli samples were susceptible to amikacin (100% and cefepime (72% and resistant to ampicillin (100% and nitrofurantoin (94%. Eighteen samples (32.7% had papG gene, of which 17 (30.9% samples had papGII gene and 1 sample (1.8% had papGIII gene; papGI gene was not detected in any of the samples. Conclusion: The results of the present study showed that papC and papGI genes are the most common Pap fimbriae adhesion-encoding genes in E. coli isolated from urinary tract infection. The difference between the results of this study with those of other studies is due to geographic diversity.

    Full Text Available Abstract Background We have previously shown that use of an EC brush device in combination with the Rovers Cervex-Brush (SurePath broom offered no significant improvement in EC recovery. Here we determine if use of additional collection devices enhance the diagnostic utility of the SurePath Pap for gynecologic cytology. Methods After informed consent, 37 women ages 18–56 receiving their routine cervical examinations were randomized into four experimental groups. Each group was first sampled with the SurePath broom then immediately re-sampled with an additional collection device or devices. Group 1: Rover endocervix brush (n = 8. Group 2: Medscand CytoBrush Plus GT (n = 7. Group 3: Rover spatula + endocervix brush (n = 11. Group 4: Medscand spatula + CytoBrush Plus GT (n = 11. Results Examination of SurePath broom-collected cytology yielded the following abnormal diagnoses: atypia (n = 2, LSIL (n = 5 and HSIL (n = 3. Comparison of these diagnoses to those obtained from paired samples using the additional collection devices showed that use of a second and or third device yielded no additional abnormal diagnoses. Importantly, use of additional devices did not improve upon the abnormal cell recovery of the SurePath broom and in 4/10 cases under-predicted or did not detect the SurePath broom-collected lesion as confirmed by cervical biopsy. Finally, in 36/37 cases, the SurePath broom successfully recovered ECs. Use of additional devices, in Group 3, augmented EC recovery to 37/37. Conclusions Use of additional collection devices in conjunction with the SurePath broom did not enhance diagnostic utility of the SurePath Pap. A potential but not significant improvement in EC recovery might be seen with the use of three devices.

    Full Text Available Lo studio esamina la validità dell’Elicited Oral Imitation Test (EI nella misurazione delle conoscenze implicite e delle strategie di processing. Si basa sull’ipotesi elaborata da Erlam secondo il quale l’EI è ricostruttivo, cioè richiede agli apprendenti di processare l’input orale e non di ripeterlo meccanicamente. La struttura misurata nello studio è il participio passato: la scelta è motivata dal fatto che si tratta di una struttura problematica a diversi livelli di competenza e richiede la capacità di processare tratti morfologici e sintattici allo stesso tempo (Salvi, Vanelli, 2004.I partecipanti sono 26 studenti cinesi di livello A2 e B1 che, all'epoca, avevano frequentato per circa 400 ore un corso di lingua italiana all'Università degli Studi di Milano. Lo studio utilizza, oltre all’EI, altre due forme di valutazione: un Untimed Grammaticality Judgment Test (UGJT e un Metalinguistic Knowledge Test (MKT. Lo studio ha dimostrato che l'EI ha un debole correlazione con  l'UGJT e con l’MKT, a conferma del fatto che gli studenti hanno fatto affidamento su due tipi di competenze differenti che possono essere identificate con le conoscenze implicite e il processing nel caso dell'EI e con le conoscenze esplicite nel caso dell’UGJT e dell’MKT. I dati raccolti nello studio hanno anche evidenziato una correlazione tra UGJT e MKT a riprova che i due tipi di valutazione richiedono competenze basata su costrutti simili.  The elicited oral imitation test as a tool for measurement of knowledge and skills of implied processingThe study examined the validity of the Elicited Oral Imitation Test (EI in the measurement of implicit knowledge and processing strategies.

    Objective: To determine the agreement/variability between colposcopic findings, Pap smear cytology and histopathological diagnosis in gynaecology patients. Methods: The cross-sectional cohort study was conducted from October 2010 to September 2011 at the Fauji Foundation Hospital, Rawalpindi, and comprised women who presented to the out-patient department with various gynaecological complaints. Colposcopy was performed in all women with unhealthy cervix during gynaecological examination, abnormal Pap smear report, recurrent vaginal discharge and postcoital bleeding. Pap smear was performed before colposcopy if not done earlier. Colposcopic findings were recorded on a specially-designed proforma. Biopsies from abnormal areas were taken and sent for histopathology. Colposcopic findings were compared with histopathology and Pap smear reports The agreement between the methods was evaluated by using Kappa coefficient and chi square test at a significance level of 5 percent. Results: The mean age of the 143 women was 44 8.5 years (range: 25-72 years). Colposcopic findings were normal in 66(46 percent) women, while 77(54 percent) had abnormal findings and among the latter, 62(80.5 percent) had abnormal histopathology, indicating strong agreement (K=0.65; p<0.001). Pap smear report was abnormal in 48(33.5 percent) cases and among them histopathology was abnormal in 28(58 percent). In the remaining 95(66.4 percent) patients with normal Pap smear, histopathology was abnormal in 44((46 percent), indicating weak agreement between Pap smear and histopathological diagnosis (K=0.10; p=0.08). Conclusion: There was a strong agreement between colposcopic findings and histopathological diagnosis. However, agreement between cytological findings and colposcopic findings and cytology and histopathological diagnosis remained weak. (author)

    BACKGROUND Understanding women’s psychological barriers to getting Papanicolaou (Pap) screening has potential to impact cancer disparities. This study examined pain perceptions of Pap testing among Black, Latina and Arab women and goal setting to receive Pap tests. METHODS Data on 420 women, a longitudinal study, were analyzed using Chi-square tests of differences and generalized linear mixed models. RESULTS At baseline, 30.3% of Black and 35.5% of Latina women perceived Pap tests to be very painful compared to 24.2% of Arab women. Perceptions of pain influenced goal settings, such as scheduling a first ever Pap test (Odds ratio = 0.58, 95% Confidence interval: 0.14-0.94). Immediately following the intervention, women’s perception that Pap tests are very painful significantly declined (P-valuetest is very painful significantly reduces the likelihood of Black, Latina and Arab women setting the goal to schedule their first ever Pap test. Latina women are the least likely to improve their perception that the Pap test is very painful, though national statistics show they have the highest rates of morbidity and mortality from cervical cancer. These findings are instructive for designing tailored interventions to break down psychological barriers to Pap screening among underserved women. PMID:23288606

    Objective: To investigate the clinical value of serum PSA and PAP determinations in diagnosis of prostate cancer patients. Methods: The serum PSA and PAP levels of 98 prostate cancer patients, 45 prostate benign disease patients and 40 normal subjects were tested by IRMA. Results: The serum PSA and PAP levels of prostate cancer patients were significantly higher than those in prostate benign disease patients and normal controls (P < 0.01). The diagnostic sensitivity and specificity of serum PSA for prostate cancer were 93.9% and 93.3% respectively. The diagnostic sensitivity and specificity of serum PAP for prostate cancer were 71.4% and 91.1% respectively. Conclusion: The determination of serum PSA and PAP was of high clinical value for diagnosis of early prostate cancer. It could be used as an important reference parameter for the clinical staging, follow-up of treatment result and prediction of prognosis

    Full Text Available Il patrimonio edilizio urbano è un bene che caratterizza l’identità dell’uomo che con esso ha vissuto; la conoscenza della realtà originaria, la conservazione e valorizzazione nel tempo comportano interventi di tipo documentale che possono interessare sia gli aspetti costruttivi degli edifici, connessi a dimensioni e geo-localizzazione, sia quelli legati alla forma urbana, sia ancora altri più specifici di tipo storico-artistico e materico. Le nuove tecnologie laser di misura terrestre, integrate da sensori di posizionamento e fotografici, consentono di rilevare in tempi ridotti e di rappresentare anche spazialmente sia singole unità edilizie sia interi insediamenti urbani. Le grandi quantità di dati acquisiti costituiscono un arricchimento della conoscenza geometrica di base, fornita in genere da rappresentazioni cartografiche “vettoriali o raster”. Il lavoro descrive un test di scansione laser, statica e cinematica, avviato sul territorio di Dalmine (Bergamo nell’ambito di un programma di interventi comunali di tutela paesaggistica, conservazione dei caratteri costruttivi e valorizzazione degli insediamenti storici della città, realizzati negli anni venti del secolo scorso e identificativi del suo passato di città-industria. L’approccio al rilievo tende altresì a validare una procedura operativa, basata su componenti tecnologiche innovative, semplice, sufficientemente economica e convenientemente applicabile all’indagine su aree urbane.

    Although historic perfluorinated compounds are currently under scrutiny and growing regulatory control in the world, little is known about human exposure to other polyfluorinated compounds presently in use. Fluorotelomer alcohols (FTOHs) and polyfluoroalkyl phosphate esters (PAPs) are known to degrade to terminal perfluorinated acids and toxic reactive intermediates through metabolic pathways. Therefore, it is important to characterize their human exposure by the identification of unique biomarkers. With the use of liquid chromatography-mass spectrometry-time-of-flight analysis (LC-MS-TOF), we developed a workflow for the identification of metabolites for the 8:2 FTOH and 8:2 diPAP. Analysis of serum and urine of dosed rats indicated the 8:2 FTOH-sulfate and the 8:2 diPAP as potential biomarkers. These compounds, as well as 25 other fluorinated compounds and metabolites, were analyzed in human serum and urine samples from the general population (n = 100) and office workers (n = 30). The 8:2 FTOH-sulfate was measured for the first time in human samples in 5 to 10% of the serum samples, ranging from 50 to 80 pg/mL. The 8:2 diPAP was measured in 58% of the samples, ranging from 100 to 800 pg/mL. This study indicates the FTOH-sulfate conjugate as a biomarker of exposure to FTOHs and PAPs in humans.

    Purpose Identification of risk for CPAP nonadherence prior to home treatment is an opportunity to deliver targeted, adherence interventions. Study objectives included (1) test a risk screening questionnaire to prospectively identify CPAP nonadherence risk among adults with newly-diagnosed OSA; (2) reduce the questionnaire to a minimum item set that effectively identifies 1-month CPAP nonadherence; and (3) examine the diagnostic utility of the screening index. Methods A prospective, longitudinal study at two clinical sleep centers in the U.S. included adults with newly diagnosed OSA (n=97; AHI ≥ 5 events/hr) by polysomnogram (PSG) consecutively recruited to participate. After baseline participant and OSA characteristics were collected, a risk screening questionnaire was administered immediately following CPAP titration polysomnogram. One-month objective CPAP use was collected. Results Predominantly white (87%) males (55%) and females (45%) with obesity (BMI 38.3 kg/m2; SD 9.3) and severe OSA (AHI 36.8; SD 19.7) were included. One-month CPAP use was 4.25hrs/night (SD 2.35). Nineteen questionnaire items (I-NAP) reliably identified nonadherers defined at CPAP use (Wald X2[8] =34.67, p60% (63%). Conclusion A risk screening questionnaire employed immediately after titration PSG may reliably identify CPAP nonadherers and permit the delivery of targeted interventions to prevent or reduce nonadherence. This novel approach may enhance cost-effectiveness of care and permit appropriate allocation of resources for CPAP adherence. PMID:24595715

    Systematic reviews and meta-analyses of test accuracy studies are increasingly being recognised as central in guiding clinical practice. However, there is currently no dedicated and comprehensive software for meta-analysis of diagnostic data. In this article, we present Meta-DiSc, a Windows-based, user-friendly, freely available (for academic use) software that we have developed, piloted, and validated to perform diagnostic meta-analysis. Meta-DiSc a) allows exploration of heterogeneity, with a variety of statistics including chi-square, I-squared and Spearman correlation tests, b) implements meta-regression techniques to explore the relationships between study characteristics and accuracy estimates, c) performs statistical pooling of sensitivities, specificities, likelihood ratios and diagnostic odds ratios using fixed and random effects models, both overall and in subgroups and d) produces high quality figures, including forest plots and summary receiver operating characteristic curves that can be exported for use in manuscripts for publication. All computational algorithms have been validated through comparison with different statistical tools and published meta-analyses. Meta-DiSc has a Graphical User Interface with roll-down menus, dialog boxes, and online help facilities. Meta-DiSc is a comprehensive and dedicated test accuracy meta-analysis software. It has already been used and cited in several meta-analyses published in high-ranking journals. The software is publicly available at http://www.hrc.es/investigacion/metadisc_en.htm.

    Objectives: The aim of this study was to estimate the proportion of women undergoing Papanicolaou (Pap) smear examinations, and the frequency of epithelial cell abnormalities in a teaching hospital in one emirate of the United Arab Emirates (UAE) during a three-year period. Methods: A retrospective study of 602 patient records from July 2007 to July 2010 was done in a teaching hospital in Ajman, UAE. The variables studied were age, ethnicity, menopausal status, and abnormalities in the Pap smear. Data were analysed using the Statistical Package for the Social Sciences and presented mainly as percentages; to assess associations, the chi-square test was used. Results: The total number of outpatients who attended the Obstetrics & Gynaecology Department from July 2007 to July 2010 was 150,111 patients, of which 602 (0.4% of the total) had a Pap smear test. The sample was 50.1% Arabs and 49.9% other nationalities. While 73% of the outpatients had specific complaints, 27% came for a routine screening. Epithelial cell abnormalities were seen in 3.3% of the sample, with atypical squamous cells of undetermined significance (ASCUS) found in 1.8%, low-grade squamous intraepithelial lesions (LSILs) found in 1.2%, and high-grade squamous intraepithelial lesions (HSILs) found in 0.3%. There were no cases of squamous cell carcinoma. Conclusion: Voluntary routine Pap smear screening was remarkably low in the study group. ASCUS was the most common epithelial cell abnormality. Community health education and opportunistic screening for cervical cancer are recommended for both national and expatriate women in the region. PMID:23275844

    Objective: To evaluate the performance of visual inspection of cervix (VIA) after application of 3% acetic acid in cervical cancer screening in comparison with PAP smear. Results: Out of 540 subjects, 356 were negative with both screening techniques. One hundred and fifty-six subjects were positive with VIA (28.9%) while PAP smear was positive in seventy-eight subjects (14.4%). The sensitivity of VIA was 93.9% and of PAP smear was 46.9%. Corresponding specificities were 30.4% and 69.5%. There was no significant difference between the positive predictive value (PPV) of both test (p<0.05). The accuracy of VIA was 77.5% compared to 52.8% of PAP smear. The difference was highly significant (p < 0.01). Conclusion: These results indicate that VIA is more sensitive and has a higher accuracy as compared to PAP smear. It could, therefore, be valuable in detection of precancerous lesions of cervix. Low cost, easy applicability and immediate results make VIA a useful screening test in developing countries like Pakistan as compared to PAP smear. (author)

    ENEA (Italian National Agency for New Technologies, Energy and the Environment) is conducting a large research and development programme on innovative vehicles with high energy efficiency and low environmental impact. In particular conducts activities on electric and hybrid vehicles. Testing and evaluation activities play a strong role in this programme. A complete characterization chain has been then defined and set up with a network of facilities which covers main testing needs for single components, subsystems and complete vehicles, in simulated and real operating conditions. The test facility which has been realised is able to experiment and fully characterise complete drive-trains (and subsystems) for pure electric and hybrid vehicles. It is composed by a different section for each subsystem: 1) power generation; 2) energy storage and management; 3) driving motors. Each section acts as an experimental island, able to operate alone or jointly with the other sections. In fact, all the sections are remotely controlled and managed in order to create different assembly of the drive-train. The facility has been sized to allow the testing of drive-trains and subsystems of small and medium-sized vehicles (up to minibuses), but an extension to larger vehicles is possible. During 1996 and part of 1997 the Drive train Test Facility has been completed and made operative. This paper mainly presents the final configurations of these novel testing systems with peculiar features and characteristics.

    Recent US data indicate that women of Vietnamese descent have higher cervical cancer incidence rates than women of any other race/ethnicity, and lower levels of Pap testing than white, black, and Latina women. Our objective was to provide information about Pap testing barriers and facilitators that could be used to develop cervical cancer control intervention programs for Vietnamese American women. We conducted a cross-sectional, community-based survey of Vietnamese immigrants. Our study was conducted in metropolitan Seattle, Washington, DC. A total of 1532 Vietnamese American women participated in the study. Demographic, health care, and knowledge/belief items associated with previous cervical cancer screening participation (ever screened and screened according to interval screening guidelines) were examined. Eighty-one percentage of the respondents had been screened for cervical cancer in the previous three years. Recent Pap testing was strongly associated (p<0.001) with having a regular doctor, having a physical in the last year, previous physician recommendation for testing, and having asked a physician for testing. Women whose regular doctor was a Vietnamese man were no more likely to have received a recent Pap smear than those with no regular doctor. Our findings indicate that cervical cancer screening disparities between Vietnamese and other racial/ethnic groups are decreasing. Efforts to further increase Pap smear receipt in Vietnamese American communities should enable women without a source of health care to find a regular provider. Additionally, intervention programs should improve patient-provider communication by encouraging health care providers (especially male Vietnamese physicians serving women living in ethnic enclaves) to recommend Pap testing, as well as by empowering Vietnamese women to specifically ask their physicians for Pap testing.

This was depending on the excessive length of the drum designed also for counter-current mode, so that ashes melted in the first part solidify in the second part because of heat losses. In conclusion, plant operation resulted satisfactory, also under the environmental aspects, despite of the very severe test conditions, with high chlorine content and the presence of aromatic compounds and copper, which acts as catalyst in the novo-synthesis of dioxins. Incineration and co-incineration of sewage sludge and hazardous compounds were therefore demonstrated to be a safe and viable disposal option.

    Many evidences illustrate that the Pap smear screening successfully reduces if the cervical cancer could be detected and treated sufficiently early. People with disability were higher comorbidity prevalence, and less likely to use preventive health care and health promotion activities. There were also to demonstrate that people with visual impairment has less access to appropriate healthcare services and is less likely to receive screening examinations. In Taiwan, there was no study to explore utilization of Pap smear, associated factors and use barriers about Pap smear screening test among women with visual impairment. The purpose is to explore the utilization and barriers of using Pap smear for women with visual impairment in Taiwan. To identify the barriers of women with visual from process of receiving Pap smear screening test. The cross-sectional study was conducted and the totally 316 participators were selected by stratified proportional and random sampling from 15 to 64 year old women with visual impairment who lived in Taipei County during December 2009 to January 2010. The data was been collected by phone interview and the interviewers were well trained before interview. The mean age was 47.1 years old and the highest percentage of disabled severity was mile (40.2 %). Totally, 66.5 % of participators were ever using Pap smear and 38.9 % used it during pass 1 year. Their first time to accept Pap smear was 38.8 year old. There was near 50 % of them not to be explained by professionals before accepting the Pap smear. For non-using cases, the top two percentage of barriers were "feel still younger" (22.3 %), the second was "there's no sexual experience" (21.4 %). We found the gynecology experiences was key factor for women with visual impairment to use Pap smear, especially the experiences was during 1 year (OR = 4). Associated factors and barriers to receive Pap smear screening test for women with visual impairment can be addressed through interventions

    The aim of this study was to determine the association between pelvic organ prolapse (POP) and non-human papillomavirus (HPV) Papanicolaou (Pap) smear abnormalities. This was a retrospective cohort study of women aged 40 to 70 years who presented for consultation at our institution between 2010 and 2015 and had results of a Pap smear and HPV test available within 5 years of their visit. We extracted demographic information, medical and social history, Pap smear, and HPV results from the electronic medical record. Associations between the presence of POP and non-HPV Pap smear abnormalities were estimated using univariable and multivariable analyses. We reviewed 1590 charts and excluded 980 women, leaving 610 women in the study: 183 with POP and 427 without POP. Women with POP were significantly older (58.2 ± 7.2 vs 55.6 ± 6.6, P 10 year) history of abnormal Pap smear (24.0% vs 14.8%, P women with POP.

    The latest Italian Water Act imposes for every wastewater treatment plant a disinfection facility. Testing the disinfection efficiency is even more important when considering the potential reuse of wastewater in agriculture. The new Water Act defines emission limits for surface water either in terms of microbiological indicators either in terms of chlorine residual levels. Particularly the actual law introduces a new bacteriological indicator (Escherichia coli) instead of the ones adopted by the previous legislation (mostly faecal coliform) but it does not indicate a standard method for its analytical determination. The presented paper concerns the testing of the hydrodynamic behaviour and the hypochlorite efficiency of a disinfection facility, located in S. Rocco Monza wastewater treatment plant. Tracer tests and different hypochlorite doses were applied in order to determine the disinfection efficiency of the contact reactor. As far as microbiological standards were concerned, it was chosen to use both the indicators E. coli and faecal coliforms in order to respect the actual legislation and the need of continuity with the past. The results did not show any difference in the sensitivity of the two microbiological indicators. [Italian] L'entrata in vigore del Decreto Legislativo 152/99 ha imposto che tutti gli impianti di depurazione delle acque reflue urbane, debbano obbligaoriamente dotarsi di un trattamento di disinfezione.

Il recente decreto fissa nuovi valori limite d'emissione in acque superficiali sia in termini di organismi indice che di cloro libero residuo, introducendo alcuni elementi di novita'. In particolare, e' stato introdotto un nuovo organismo indice: l'Escherichia coli, in sostituzione di quelli precedentemente utilizzati (coliformi

    P pili are prototypical chaperone-usher pathway-assembled pili used by Gram-negative bacteria to adhere to host tissues. The PapC usher contains five functional domains: a transmembrane β-barrel, a β-sandwich Plug, an N-terminal (periplasmic) domain (NTD), and two C-terminal (periplasmic) domains, CTD1 and CTD2. Here, we delineated usher domain interactions between themselves and with chaperone-subunit complexes and showed that overexpression of individual usher domains inhibits pilus assembly. Prior work revealed that the Plug domain occludes the pore of the transmembrane domain of a solitary usher, but the chaperone-adhesin-bound usher has its Plug displaced from the pore, adjacent to the NTD. We demonstrate an interaction between the NTD and Plug domains that suggests a biophysical basis for usher gating. Furthermore, we found that the NTD exhibits high-affinity binding to the chaperone-adhesin (PapDG) complex and low-affinity binding to the major tip subunit PapE (PapDE). We also demonstrate that CTD2 binds with lower affinity to all tested chaperone-subunit complexes except for the chaperone-terminator subunit (PapDH) and has a catalytic role in dissociating the NTD-PapDG complex, suggesting an interplay between recruitment to the NTD and transfer to CTD2 during pilus initiation. The Plug domain and the NTD-Plug complex bound all of the chaperone-subunit complexes tested including PapDH, suggesting that the Plug actively recruits chaperone-subunit complexes to the usher and is the sole recruiter of PapDH. Overall, our studies reveal the cooperative, active roles played by periplasmic domains of the usher to initiate, grow, and terminate a prototypical chaperone-usher pathway pilus.

    Attitudes toward cervical cancer and participation in early detection and screening services are well known to be profoundly affected by cultural beliefs and norms. This study explored the attitudes and sociocultural beliefs on cervical cancer screening among Malaysian women. In this qualitative study, in-depth interviews were conducted with 20 Malaysian women, ages 21 to 56 years, who have never had a Papanicolaou (Pap) smear. Respondents generally showed a lack of knowledge about cervical cancer screening using Pap smear, and the need for early detection for cervical cancer. Many believed the Pap smear was a diagnostic test for cervical cancer, and since they had no symptoms, they did not go for Pap screening. Other main reasons for not doing the screening included lack of awareness of Pap smear indications and benefits, perceived low susceptibility to cervical cancer, and embarrassment. Other reasons for not being screened were related to fear of pain, misconceptions about cervical cancer, fatalistic attitude, and undervaluation of own health needs versus those of the family. Women need to be educated about the benefits of cervical cancer screening. Health education, counseling, outreach programs, and community-based interventions are needed to improve the uptake of Pap smear in Malaysia.

A idade média na amostra foi de 46,2 anos (desvio padrão 11,5, e 84% relatavam renda familiar anual menor que quinze mil dólares. Todas as mulheres falavam espanhol e apresentavam níveis reduzidos de aculturação; 96% destas informavam ter realizado TP, mas 24% não relatavam adesão às normas recomendadas de rastreamento. Entre aquelas com quarenta anos ou mais, 62% haviam realizado MM, mas somente 33% de acordo com as normas de rotina. A freqüência de conceitos equivocados sobre o câncer neste grupo de mulheres foi maior que a observada para mulheres latinas em outros estudos. Modelos logísticos multivariados para variáveis correlacionadas à conduta no rastreamento pelo TP e MM indicam que fatores como o medo do teste, vergonha e desconhecimento tiveram influência. Concluiu-se que as mulheres nesse estudo apresentaram menor freqüência de rastreamento por MM que mulheres não latinas, além de apresentarem também níveis mais reduzidos de adesão às normas de rastreamento por TP e MM.

    Full Text Available Background: Extensive screening programme of cervical Pap smear examination can detect the precancerous and cancerous lesions at an early stage and mortality & morbidity due to these lesions can be reduced. HPV infection is a known etiological agent for cervical cancer. HIV infected women are at higher risk of contracting HPV infection due to immune compromised status. Objective: Present study has been undertaken mainly to detect precancerous & cancerous lesions as well as inflammatory lesions in female patients living with HIV & to emphasize the fact that Pap smear examination should be established as a part of routine protocol for examination in HIV infected women. Methods: The study was carried out on 369 HIV infected females attending Integrated Counselling &Testing Centre of government institute. As controls, 142 females (not falling under high risk category, attending the Obstetrics& Gynaecology OPD with various gynaecological complaints were taken & results were compared. Results: Squamous cell abnormalities were found about four times high as compared to control group. High incidences of squamous cell abnormalities were noted in patients with high parity (parity three or more. Conclusion: Regular gynaecological examination including Pap smear examinations is highly recommended for HIV infected females. Pap smear examination is a simple, cheap, safe & practical diagnostic tool for early detection of cervical cancer in high risk population.

    The integration of ordinary differential equations systems (ODEs) is of significant concern to tropospheric and stratospheric chemistry modelers. The solution of the ODEs requires a large computational effort because of their stiff nature; in a three-dimensional photochemical model the solution of the ODEs required at least 70% of the total CPU time. Several numerical integration techniques exist which attempt to provide accurate and computationally efficient solutions. In this work it is presented a comparison of some of the techniques in terms of solution accuracy and required computational time. It has been compared the Hybrid Solver (Young and Boris, 1977), the Quasi Steady-State Approximation method (Hesstvedt et al., 1978) and the Chemical Solver for Ordinary Differential Equations (Aro, 1996), by using the CALGRID photochemical model. The accuracy is evaluated by comparing the results of every method with the solutions obtained by the Livermore Solver for Ordinary Differential Equations (Hindmarsh, 1980). The comparison has been made varing the parameters of the error tolerances, and taking into account the trade-off between solution accuracy and computational efficiency.

    Di-(2-ethylhexyl) phthalate (DEHP), commonly referred to as di-octyl phthalate, is an important production chemical in the US. In addition to its major use as an additive in plastics, DEHP is widely used to evaluate the effectiveness of high efficiency particulate air (HEPA) filters. Historically, DEHP was also used in quantitative fit testing for respirators. Evaluations of this compound a decade ago showed that it can induce hepatocellular carcinomas in laboratory animals. Although most Department of Energy (DOE) facilities have since discontinued using DEHP in respirator fit testing, DEHP continues to be used for evaluating HEPA filters. This report summarizes available information on the toxicity, mutagenicity, carcinogenicity, and other hazards and problems posed by DEHP, specifically with reference to HEPA filter testing. Information on work practice improvements as well as the availability and suitability of DEHP substitutes are also presented. This material should assist the DOE in the safe use of this material.

    Nowadays, the increasing oil consumption throughout the world induces crucial economical, security, and environmental problems. As a result, intensive researches are undertaken to find appropriate substitution to fossil fuels. In view of the large amount of eucalyptus trees present in arid areas, we focus in this study on the investigation of using eucalyptus biodiesel as fuel in diesel engine. Eucalyptus oil is converted by transesterification into biodiesel. Eucalyptus biodiesel characterization shows that the physicochemical properties are comparable to those of diesel fuel. In the second phase, a single cylinder air-cooled, DI diesel engine was used to test neat eucalyptus biodiesel and its blends with diesel fuel in various ratios (75, 50, and 25 by v%) at several engine loads. The engine combustion parameters such as peak pressure, rate of pressure rise, and heat release rate are determined. Performances and exhaust emissions are also evaluated at all operating conditions. Results show that neat eucalyptus biodiesel and its blends present significant improvements of carbon monoxide, unburned hydrocarbon, and particulates emissions especially at high loads with equivalent performances to those of diesel fuel. However, the NOx emissions are slightly increased when the biodiesel content is increased in the blend.

    To estimate the incidence of abnormal cervical cytology by ThinPrep Pap-tests and cervical intraepithelial neoplasia (CIN) in young adult reproductive-aged Thai women. A total of 1254 women distributed in all regions of Thailand were monitored from 2002 through 2004. Women were screened for abnormal cervical cytology using the ThinPrep method every 6 months. Interpretation of cervical cytology was based on the Bethesda system, version 2001. Women who had the ThinPrep Pap results as atypical squamous cells of undetermined significance or worse underwent colposcopic examination. The ThinPrep and all cervical tissue samples obtained from diagnostic or therapeutic procedures were analyzed and reviewed by Covance Central Laboratory Service, Inc., Indianapolis, USA. The cumulative incidence of abnormal ThinPrep Pap-tests was as follows: 15.3 per 100 woman years (WY) (95% confidence interval [CI] 12.3, 18.9) at 6 months; 12.3 per 100 WY (95% CI 10.3, 14.6) at 12 months; and 11.6 per 100 WY (95% CI 10.0, 13.5) at 18 months. Of 1448.6 woman years of follow up, the incidence of CIN1 was 4.1 per 100 WY (95% CI 3.2, 5.3); CIN2 0.8 per 100 WY (95% CI 0.4, 1.4); and CIN3 0.6 per 100 WY (95% CI 0.3, 1.2). The incidence of abnormal ThinPrep Pap-test and CIN in young adult Thai women had been reported. No comparable data is available.

    The workplace has been deemed a suitable location for educating many women at once about cancer screening. To determine how group education about early diagnostic methods for breast and cervical cancer effects women's behavior and readiness to receive mammography and Pap smear. This semi-interventional study was conducted at a textile factory in Istanbul, Turkey. Female workers (n= 125) were included in the study. A participant identification form and knowledge evaluation form developed for this study, along with the transtheoretical model, were used to collect data. A 45-min interactive group education was given to the participants. Upon contacting participants 3 months after group education, 15.4% (n = 11) stated that they had since received a mammogram and 9.8% (n = 7) a Pap smear. As suggested by the transtheoretical model, group education increased participants' readiness to receive cancer screening, along with their knowledge of breast and cervical cancer. Group education positively impacted women's knowledge of cancer and their readiness to receive mammography and Pap smear. Group education can potentially create awareness of cancer screening tests among women and improve their readiness to receive such tests.

    To assess the impact of smear test in the fight against cervix uteri cancer in Senegal. This was a descriptive cross-sectional study of 1836 Pap smears performed in patients over 15 years during several screening campaigns in Senegal conducted between June 2010 and June 2012. We analyzed epidemiological data, pathological smears, and the proposed management. In 69% of cases, the women were less than 45 years old. They were mostly multiparous and did not use contraceptive methods before. The smears were interpreted in 91.4% (n=1661) and were pathological in 5.2% of cases. They revealed mainly atypical squamous cells of undetermined significance, squamous intraepithelial low-grade lesions, and squamous intraepithelial high-grade lesions, respectively in 2.5% (n=46), 1.7% (n=30) and 1% (n=19) of cases. Multiparity, early marriages were the main risk factors. Patients with pathological smars had colposcopy with cryotherapy (23 cases), and colposcopy and biopsy (13 cases). A hysterectomy was performed in 4 cases. The pathological smear rate found in this study confirms the interest to continue cervical cancer screening with this practice. Strengthening of its geographical and financial access through a national prevention program will effectively help to lower cases of cervical cancer. Copyright © 2016 Elsevier Masson SAS.

    Full Text Available Abstract Objective Hyperchromatic crowded groups (HCG, a term first introduced into the cytology literature by DeMay in 1995, are commonly observed in Pap tests and may rarely be associated with serious but difficult to interpret lesions. In this study, we specifically defined HCG as dark crowded cell groups with more than 15 cells which can be identified at 10× screening magnification. Methods We evaluated consecutive liquid-based (Surepath Pap tests from 601 women (age 17–74 years, mean age 29.4 yrs and observed HCG in 477 cases. In all 477 HCG cases, Pap tests were found to be satisfactory and to contain an endocervical sample. HCG were easily detectible at 10× screening magnification (size up to 400 um, mean 239.5 um and ranged from 1 to 50 (mean 19.5 per Pap slide. Results HCG predominantly represented 3-Dimensional groups of endocervical cells with some nuclear overlap (379/477 – 79%, reactive endocervical cells with relatively prominent nucleoli and some nuclear crowding (29/477 – 6%, clusters of inflammatory cells (25/477 – 5.2%, parabasal cells (22/477 – 4.6%, endometrial cells (1/477 – 0.2%. Epithelial cell abnormalities (ECA were present in only 21 of 477 cases (4.6%. 18 of 21 women with HCG-associated ECA were less than 40 years old; only 3 were =/> 40 years. HCG-associated final abnormal Pap test interpretations were as follows: ASCUS (6/21 – 28%, LSIL (12/21 – 57%, ASC-H (2/21 – 9.5%, and HSIL/CIN2-3 (3/21 – 14%. The association of HCG with ECA was statistically significant (p = 0.0174. chi-square test. In patients with ECA, biopsy results were available in 10 cases, and 4 cases of biopsy-proven CIN2/3 were detected. Among these four cases, HCG in the Pap tests, in retrospect represented the lesional high grade cells in three cases (one HSIL case and two ASC-H cases. Interestingly, none of the 124 cases without HCG were found to have an epithelial cell abnormality. Conclusion We conclude: a. HCG are observed

    Cancer cervix is the leading cause of cancer deaths in females in developing countries and one in five women suffering from cervical cancer lives in India. The aim of this study is to determine the awareness about cervical cancer and Pap smear among nurses working in a tertiary care institute. Study Setting and Design: Cross-sectional survey in a tertiary care institute. Nurses working at our institute excluding those who have worked or working in the Obstetrics and Gynecology department were provided with a pre-designed questionnaire testing their knowledge about cervical cancer. Approximately, 86% were aware about cancer cervix and 69% were aware of a pre-cancerous stage. 42.3% were not aware of any risk factor and 27.6% were not aware of any symptom of cancer cervix. 86.2% were aware about Pap smear, but only 58.6% were aware that facilities of Pap smear were available at our hospital. Knowledge about cervical cancer and awareness of Pap smear as screening test was inadequate in nursing staff. Awareness programs about cervical cancer and screening are needed to increase awareness for this preventable condition. There is a need to arrange reorientation programs to sensitize nurses and establish cytology clinics to offer facilities for easily accessible and affordable screening.

Although these phenomena are drastic, the molecular mechanisms underlying the cellular changes are mostly unknown. In this study, we focused on the pancreatitis-associated protein (PAP) family members of the secretory lectins and characterized their expression in the IL of CS model rats because we had identified two members of this family as up-regulated genes in our previous microarray analysis. RT-PCR and histological studies demonstrated that prominent PAP-I and PAP-II expression was induced in melanotrophs in the early stages of CS, while another family member, PAP-III, was not expressed. We further examined the regulatory mechanisms of PAP-I and PAP-II expression and revealed that both were induced by the decreased dopamine levels in the IL under CS. Because the PAP family members are implicated in cell survival and proliferation, PAP-I and PAP-II secreted from melanotrophs may function to sustain homeostasis of the IL under CS conditions in an autocrine or a paracrine manner.

  20. CKI isoforms α and ε regulate Star–PAP target messages by controlling Star–PAP poly(A) polymerase activity and phosphoinositide stimulation

    2011-01-01

    Star–PAP is a non-canonical, nuclear poly(A) polymerase (PAP) that is regulated by the lipid signaling molecule phosphatidylinositol 4,5 bisphosphate (PI4,5P2), and is required for the expression of a select set of mRNAs. It was previously reported that a PI4,5P2 sensitive CKI isoform, CKIα associates with and phosphorylates Star–PAP in its catalytic domain. Here, we show that the oxidative stress-induced by tBHQ treatment stimulates the CKI mediated phosphorylation of Star–PAP, which is critical for both its polyadenylation activity and stimulation by PI4,5P2. CKI activity was required for the expression and efficient 3′-end processing of its target mRNAs in vivo as well as the polyadenylation activity of Star–PAP in vitro. Specific CKI activity inhibitors (IC261 and CKI7) block in vivo Star–PAP activity, but the knockdown of CKIα did not equivalently inhibit the expression of Star–PAP targets. We show that in addition to CKIα, Star–PAP associates with another CKI isoform, CKIε in the Star–PAP complex that phosphorylates Star–PAP and complements the loss of CKIα. Knockdown of both CKI isoforms (α and ε) resulted in the loss of expression and the 3′-end processing of Star–PAP targets similar to the CKI activity inhibitors. Our results demonstrate that CKI isoforms α and ε modulate Star–PAP activity and regulates Star–PAP target messages. PMID:21729869

    Full Text Available Abstract Background Prevalence of type 2 diabetes mellitus is increasing due to lifestyle changes, particularly affecting those genetically at risk. We developed DiAlert as a targeted group-based intervention aimed to promote intrinsic motivation and action planning for lifestyle changes and weight loss in first degree relatives of patients with type 2 diabetes mellitus. The main objective of the pilot of the DiAlert intervention was to assess fidelity, feasibility and acceptability prior to starting the randomized controlled trial. Methods Individuals with a family history of type 2 diabetes mellitus were self-identified and screened for eligibility. DiAlert consists of two group sessions. Feasibility, fidelity, acceptability and self-reported perceptions and behavioral determinants were evaluated in a pre-post study using questionnaires and observations. Determinants of behavior change were analyzed using paired-samples t tests and Wilcoxon signed rank tests. Results DiAlert was delivered to two groups of first degree relatives of patients with type 2 diabetes mellitus (N = 9 and N = 12. Feasibility and fidelity were confirmed. Overall, the DiAlert group sessions were positively evaluated (8.0 on a scale of 1 to 10 by participants. The intervention did not impact perceived susceptibility or worry about personal diabetes risk. Action planning with regard to changing diet and physical activity increased. Conclusions DiAlert proved feasible and was well-accepted by participants. Positive trends in action planning indicate increased likelihood of actual behavior change following DiAlert. Testing the effectiveness in a randomized controlled trial is imperative. Trial registration Netherlands National Trial Register (NTR: NTR2036

    The purpose of this investigation was to evaluate the impact of the vaginal milieu on the presence of abnormal Pap smears and a positive human papilloma virus (HPV) test. A cross-sectional study was conducted between June 2014 and May 2015, evaluating the vaginal discharge by fresh wet mount microscopy and comparing these data with Pap smear findings. Wet mount slides were scored for bacterial vaginosis (BV), aerobic vaginitis (AV), presence of Candida and Trichomonas vaginalis. Cytologic evaluation was done on all Pap smears according to the Bethesda criteria. The cobas© HPV Test (Roche) was performed for HPV detection. A total of 622 cases were evaluated. The mean age of the patients was 41.6 ± 10.65 years (range 21-75). Eighty-three women (13.3 %) had a cytology result worse than low-grade squamous intraepithelial lesion (LSIL). When comparing this group with the one with normal or minor [atypical squamous cells of undetermined significance (ASC-US) or LSIL] Pap smear abnormalities, there were no differences in the presence of Candida (32.5 % vs. 33.2 %, p = 1.0), absence of lactobacilli (38.6 % vs. 32.5 %, p = 0.32) or BV (20.5 % vs. 13.2 %, p = 0.09). On the other hand, moderate or severe inflammation (msI) (41.0 % vs. 28.8 %, p = 0,04), moderate or severe AV (msAV) (16.9 % vs. 7.2 %, p = 0.009) and msAV/BV (37.3 % vs. 20.0 %, p = 0.001) were more common in women with such major cervical abnormalities. No significant association was found between deviations of the vaginal milieu and high-risk HPV infection. The presence of msI or msAV, but not BV, is independently associated with an increased risk of major cervical cytological abnormalities, but not with HPV infection.

    Organized screening based on Pap tests has substantially reduced deaths from cervical cancer in many countries, including Australia. However, the impact of the program depends upon the degree to which women participate. A new method of screening, testing for human papillomavirus (HPV) DNA to detect the virus that causes cervical cancer, has recently become available. Because women can collect their own samples for this test at home, it has the potential to overcome some of the barriers to Pap tests. The iPap trial will evaluate whether mailing an HPV self-sampling kit increases participation by never- and under-screened women within a cervical screening program. The iPap trial is a parallel randomized controlled, open label, trial. Participants will be Victorian women age 30–69 years, for whom there is either no record on the Victorian Cervical Cytology Registry (VCCR) of a Pap test (never-screened) or the last recorded Pap test was between five to fifteen years ago (under-screened). Enrolment information from the Victorian Electoral Commission will be linked to the VCCR to determine the never-screened women. Variables that will be used for record linkage include full name, address and date of birth. Never- and under-screened women will be randomly allocated to either receive an invitation letter with an HPV self-sampling kit or a reminder letter to attend for a Pap test, which is standard practice for women overdue for a test in Victoria. All resources have been focus group tested. The primary outcome will be the proportion of women who participate, by returning an HPV self-sampling kit for women in the self-sampling arm, and notification of a Pap test result to the Registry for women in the Pap test arm at 3 and 6 months after mailout. The most important secondary outcome is the proportion of test-positive women who undergo further investigations at 6 and 12 months after mailout of results. The iPap trial will provide strong evidence about whether HPV self

    Full Text Available Obstructive Sleep Apnea (OSA is associated with medical and neurobehavioral morbidity across the lifespan. Positive airway pressure (PAP treatment has demonstrated efficacy in treating OSA and has been shown to improve daytime functioning in adults, but treatment adherence can be problematic. There are nearly no published studies examining functional outcomes such as academic functioning in adolescents treated with PAP. This study was conducted as an initial step towards determining whether PAP treatment improves daytime functioning among adolescents with OSA.Self-reported academic grades, self- and parent-reported academic quality of life, and objectively-measured attention were assessed before and after PAP was clinically initiated in a sample of 13 obese adolescents with OSA, as well as 15 untreated obese Controls without OSA. Based on adherence data, the treated group was divided into PAP Users (n = 6 and Non-Adherent participants (n = 7.Though demographically similar, the three groups significantly differed in how their academic performance and attention scores changed from baseline to follow-up. Non-Adherent participants showed worsening functioning over time, while PAP Users showed stable or improved functioning, similar to controls.Although many adolescents prescribed PAP for OSA are non-adherent to the treatment, those who adhere to treatment can display improved attention and academic functioning.

  7. Crystal structure of the P pilus rod subunit PapA.

    Full Text Available P pili are important adhesive fibres involved in kidney infection by uropathogenic Escherichia coli strains. P pili are assembled by the conserved chaperone-usher pathway, which involves the PapD chaperone and the PapC usher. During pilus assembly, subunits are incorporated into the growing fiber via the donor-strand exchange (DSE mechanism, whereby the chaperone's G1 beta-strand that complements the incomplete immunoglobulin-fold of each subunit is displaced by the N-terminal extension (Nte of an incoming subunit. P pili comprise a helical rod, a tip fibrillum, and an adhesin at the distal end. PapA is the rod subunit and is assembled into a superhelical right-handed structure. Here, we have solved the structure of a ternary complex of PapD bound to PapA through donor-strand complementation, itself bound to another PapA subunit through DSE. This structure provides insight into the structural basis of the DSE reaction involving this important pilus subunit. Using gel filtration chromatography and electron microscopy on a number of PapA Nte mutants, we establish that PapA differs in its mode of assembly compared with other Pap subunits, involving a much larger Nte that encompasses not only the DSE region of the Nte but also the region N-terminal to it.

    The Routine Pap smear test has successfully reduced the incidence of invasive cervical cancer in the presence of a proper structure for its implementation. This study was designed to assess the effect of health education on the knowledge, attitude, and uptake of Pap smear among female teachers. It was a quasi-experimental, controlled study with a pre-test, post-test design. A total of 100 respondents were recruited for each of the intervention and control groups, by the multistage sampling technique. The mean knowledge score of cervical cancer was low in both the interventions (25.5% ± 10.5) and control groups (18.9% ± 10.0) at baseline; a significant rise to 57.2% ± 20.7 was recorded after the intervention in the Intervention group (Pfree Pap smear was poor at the post-intervention phase in both the groups (P=0.45). Reported reasons for poor uptake included the respondents' dislike for the test (38.4%) and the belief that the test was not necessary (24.4%). About 20% of the respondents did not have any reason at all. Health education had no significant effect on the uptake of a free Pap smear among teachers. Despite the significant improvement in the attitude toward the test, many respondents did not like the test after than before the intervention. Sociocultural issues such as the gender of the sample collector, and system factors like few service delivery points, and the time required to access the service could have contributed to the poor uptake recorded in this study. A program designed to improve routine cervical cancer screening by Pap smear should therefore address not only the knowledge and cost, but also the sociocultural and systemic factors.

    The introduction of organized cervical cancer (CC) screening programs has drastically reduced the prevalence of CC. However the incidence is still too high, especially among elderly women. All guidelines strongly recommend a regular Papanicolaou (Pap) testing for young and middle-aged patients. On the other hand, many international professional societies no longer advise screening in women who have undergone hysterectomy, and in women aged 65 years and above, who have a previous history of regular Pap smears. Here we report the case of poorly differentiated CC, involving the pelvic lymph nodes and urinary bladder, occurring in a 79-year-old woman who regularly underwent Pap tests, with no reported cytological abnormalities. In this very rare case, the CC cells, as well as cells from metastatic lymph nodes and cells from urinary specimens, molecularly showed human papilloma virus (HPV)-53. With the limitations of a single case, this report brings important information to prevent CC in elderly patients: the utility of molecular tests to increase sensitivity of Pap smears in postmenopausal women; the importance of HPV-53 as one of the four "emergent" genotypes having a possible role in oncogenesis; and the presence of HPV-53 in lymph node metastases from cervical carcinoma, which would support the role of this virus in the maintenance of malignant status.

    Cloning and sequencing of the papA gene from uropathogenic Escherichia coli 4030 strain to investigate the differences of the sequences of the papA of UPEC4030 strain and the ones of related genes, in order to make whether or not it was a new genotype. Cloning and sequencing methods were used to analyze the sequence of the papA of UPEC4030 strain in comparison with related sequences. The sequence analysis of papA revealed a 722 bp gene and encode 192 amino acid polypeptide. The overall homology of the papA genes between UPEC4030 and the standard strains of ten F types were 36.11%-77.95% and 22.20%-78.34% at nucleotide and deduced amino acid levels. The homology between the sequence of the reverse primers and the corresponding sequence of UPEC4030 papA was 10%-66.67%. The results confirmed that UPEC4030 strain contained a novel papA variant. UPEC4030 strain could contain an unknown papA variant or the novel genotype. The pathogenic mechanism and epidemiology related need to be further studied.

    Cyprinus carpio (koi) is one of the most popular ornamental fish. A major problem for C. carpio farming is bacterial infections especially by Aeromonas hydrophila. Previously studies had shown that the Phagocytosis Activating Protein (PAP) gene was involved in the innate immune response of animals. Therefore, we attempted to identify a role for the PAP gene in the immunology of C. carpio. The expression of the PAP was found in C. carpio whole blood and increased when the fish were stimulated by inactivated A. hydrophila. In addition, PAP-phMGFP DNA was injected as an immunostimulant. The survival rate and the phagocytic index were significantly increased in the A. hydrophila infected fish that received the PAP-phMGFP DNA immunostimulant. A chitosan-PAP-phMGFP nanoparticle was then developed and feeded into fish which infected with A. hydrophila. These fish had a significantly lower mortality rate than the control. Therefore, this research confirmed a key role for PAP in protection fish from bacterial infection and the chitosan-PAP-phMGFP nanoparticle could be a good prototype for fish immunostimulant in the future.

    Since June 2013 the total feed ban of processed animal proteins (PAPs) was partially lifted. Now it is possible to mix fish feed with PAPs from non-ruminants (pig and poultry). To guarantee that fish feed, which contains non-ruminant PAPs, is free of ruminant PAPs, it has to be analysed with a ruminant PCR assay to comply with the total ban of feeding PAPs from ruminants. However, PCR analysis cannot distinguish between ruminant DNA, which originates from proteins such as muscle and bones, and ruminant DNA, which comes from feed materials of animal origin such as milk products or fat. Thus, there is the risk of obtaining positive ruminant PCR signals based on these materials. The paper describes the development of the combination of two analysis methods, micro-dissection and PCR, to eliminate the problem of 'false-positive' PCR signals. With micro-dissection, single particles can be isolated and subsequently analysed with PCR.

    This study assessed the ability of bone scintigraphy, alkaline phosphatase (ALP), total acid phosphatase (TAP), and prostatic acid phosphatase (PAP) to diagnose bone metastasis in a series of 62 patients with histologically proven prostatic cancer. Abnormal uptake was seen on the bone scan in 49 patients (79 %). A final diagnosis of bone metastasis was made in 40 patients (65 %). The sensitivity and specificity were 100 % and 59 %, respectively, for bone scintigraphy; 50 % and 96 % for ALP; 65 % and 82 % for TAP; and 73 % and 77 % for PAP. For 40 patients with bone metastasis, all of the ALP, TAP, and PAP were positive in 17 patients (43 %) and negative in 8 patients (20 %). Higher levels of ALP, TAP, and PAP tended to be associated with more extensive bone metastasis. Although serological examination showed lower sensitivity than bone scintigraphy in the diagnosis of bone metastasis, PAP may be most frequently used as a screening procedure of bone metastasis.

    Five commercial PAP RIA kits were intercompared by common RIA quality control criteria. All RIAs performed basically well although some differences existed in respect to concentration range, specific and non-specific binding, 50%-intercept, sensitivity and measurements of serum PAP in male and female controls. The latter finding may have been due to differences in antigen purity, antiserum specificity and composition of the assay medium employed. Good correlation was found between PAP determination by RIA and by enzyme assay. First measurements of PAP in patients treated for prostatic carcinoma being performed for orientation purposes are demonstrated. The PAP RIA has been introduced into our routine diagnostic and follow-up of prostatic carcinoma.

  20. Pap smears for men: a vision of the future?

    Oon, S F

    2012-02-01

    BACKGROUND: Anal intraepithelial neoplasia (AIN) rarely receives as much publicity as its neighbouring orifice, the cervix. As in the cervix, intraepithelial neoplasias are precursors to cancer in the anal canal. AIN and cervical interstitial neoplasia (CIN) undergo dysplasia as a consequence of human papillomavirus (HPV) infection. Since the advent of screening with the Pap smear in CIN, cervical cancer has plummeted to a fifth of its initial incidence. Anal cancer, however, has been rising, with a predilection for human immunodeficiency virus-infected men. HPV causes a squamous epithelial dysplasia and converts healthy tissue into AINs of increasing severity until anal cancer manifests. CLINICAL CASE: This article describes a clinical case of anogenital HPV infection refractory to medical and surgical therapy. It also describes an effective surgical excision technique associated with a good cosmetic outcome. CONCLUSIONS: The paper concludes by briefly discussing the implications of a national screening programme against AIN in the future.

    2009-03-01

    Adhesion of uropathogenic Escherichia coli to host tissues is mediated by pili, which extend from the outer cell membrane of the bacterium. Here we report molecular dynamics (MD) characterizations of the major constituent of P pili from the uropathogenic E. coli, PapA, in unliganded state and in complex with the G1 strand of the chaperone PapD. To mimic the PapA response to the gradual dissociation of the PapD G1 strand and to evaluate the role of PapA chaperone recognition sites, we also carried out MD simulations of complexes of PapA with fragments of PapD G1 strand, that leave either the P4 or both P3 and P4 sites unoccupied. Data on the unbound form of PapA indicate that, upon release of the chaperone, PapA evolves toward compact states that are likely not prone to subunit-subunit association. In line with recent experimental reports, this finding implies that chaperone release and subunit-subunit association must be concerted. Our data also indicated that the gradual unbinding of the chaperone from the PapA groove has increasingly strong structural consequences. Indeed, the release of the chaperone from the site P4, which is closest to the initiation site (P5), does not have dramatic effects on the domain structure, whereas its release from both the P4 and the adjacent P3 sites induces a quick structural transition toward a collapsed state, where the subunit groove is obstructed.

    While there are studies postulating a model of synergism between human papillomavirus (HPV) and herpes simplex virus (HSV) in cervical carcinogenesis, the frequency of anal herpes as well as its association with anal squamous intraepithelial lesions (ASILs) has been understudied in men. This study evaluates the frequency of HSV changes in anal Pap smears and its association with ASILs in a high-risk population. A computerized search for specimens associated with anal cytology that had positive findings of HSV was performed. The electronic medical records were examined for past diagnosis of herpes, HSV serology prior to or after cytology, and if the patient received treatment after cytologic diagnosis of HSV. Of the 470 anal Pap smears (Thin-prep) examined, seven had cellular changes consistent with HSV infection. All patients were asymptomatic human immunodeficiency virus (HIV) positive males with no prior HSV serology tests. Two patients had prior diagnoses of HSV infection. Cytologic abnormalities were identified in 86% ranging from atypical squamous cells of undetermined significance to high grade squamous intraepithelial lesion. Three patients were treated after the HSV cytologic diagnosis. The frequency of HSV changes in anal Pap smear is low (1.48%), but the presence of concomitant cytologic abnormalities is high (86%). While our findings suggest the possible role of HSV as a HPV co-factor in ASILs, larger studies are needed to support this. Identification of HSV infection on anal Pap smear is important for institution of patient treatment and subsequent reduction of transmission. Copyright © 2014 Wiley Periodicals, Inc.

    In paediatric moderate-to-severe asthmatics, there is significant bronchospasm, airway obstruction, air trapping causing severe hyperinflation with more positive intraplural pressure preventing passive air movement. These effects cause an increased respiratory rate (RR), less airflow and shortened inspiratory breath time. In certain asthmatics, aerosols are ineffective due to their inadequate ventilation. Bilevel positive airway pressure (BiPAP) in acute paediatric asthmatics can be an effective treatment. BiPAP works by unloading fatigued inspiratory muscles, a direct bronchodilation effect, offsetting intrinsic PEEP and recruiting collapsed alveoli that reduces the patient's work of breathing and achieves their total lung capacity quicker. Unfortunately, paediatric emergency department (PED) BiPAP is underused and quality analysis is non-existent. A PED BiPAP Continuous Quality Improvement Program (CQIP) from 2005 to 2013 was evaluated using descriptive analytics for the primary outcomes of usage, safety, BiPAP settings, therapeutics and patient disposition.

    Full Text Available Abstract Background The Malaysian Ministry of Health promotes breast self-examination (BSE for all women, and Pap smear screening every three years for all sexually active women ages 20 years and above. The objectives of this paper were to examine the practice of these two screening tests among women production workers in electronics factories, and to identify factors related to practice. Methods This was a cross-sectional survey of women production workers from ten electronics factories. Data was collected by a self-administered questionnaire from a total of 1,720 women. The chi-square test, odds ratio and binomial logistic regression were used in bivariate and multivariate analysis. Results Prevalence rates were 24.4% for BSE once a month, and 18.4% for Pap smear examination within the last three years. Women who were significantly more likely to perform BSE every month were 30 years and older, Malays, with upper secondary education and above, answered the BSE question correctly, and had a Pap smear within the last three years. The proportion of women who had a Pap smear within the last three years were significantly higher among those who were older, married, with young children, on the contraceptive pill or intra-uterine device, had a medical examination within the last five years, answered the Pap smear question correctly, and performed BSE monthly. Conclusion Screening practice rates in this study were low when compared to national rates. Socio-demographic and health care factors significantly associated with screening practice are indicative of barriers which should be further understood so that more effective educational and promotional strategies could be developed.

    Star-PAP, a nuclear phosphatidylinositol (PI) signal-regulated poly(A) polymerase (PAP), couples with type I PI phosphate kinase α (PIPKIα) and controls gene expression. We show that Star-PAP and PIPKIα together regulate 3'-end processing and expression of pre-mRNAs encoding key anti-invasive factors ( KISS1R , CDH1 , NME1 , CDH13 , FEZ1 , and WIF1 ) in breast cancer. Consistently, the endogenous Star-PAP level is negatively correlated with the cellular invasiveness of breast cancer cells. While silencing Star-PAP or PIPKIα increases cellular invasiveness in low-invasiveness MCF7 cells, Star-PAP overexpression decreases invasiveness in highly invasive MDA-MB-231 cells in a cellular Star-PAP level-dependent manner. However, expression of the PIPKIα-noninteracting Star-PAP mutant or the phosphodeficient Star-PAP (S6A mutant) has no effect on cellular invasiveness. These results strongly indicate that PIPKIα interaction and Star-PAP S6 phosphorylation are required for Star-PAP-mediated regulation of cancer cell invasion and give specificity to target anti-invasive gene expression. Our study establishes Star-PAP-PIPKIα-mediated 3'-end processing as a key anti-invasive mechanism in breast cancer. Copyright © 2018 A.P. and Laishram.

    To estimate the lifetime prevalence of Pap smear among women in Kuwait and to assess their knowledge about and attitude toward Pap smears. This was a descriptive cross-sectional study using a multistage cluster sampling method. We interviewed 299 women attending polyclinics in Kuwait using a self-administered questionnaire. Factors related to history of having a Pap smear, knowledge level, and willingness to participate in a screening program were evaluated. The lifetime prevalence of Pap smear was found to be 37% (95% CI 33-43). Forty-four percent of women in our study had a Pap smear only once in their lives. History of having at least one Pap smear was significantly related to such factors as age, total family income, marital status, history of cervical infection, and knowledge. The level of knowledge about cervical cancer varied among the participants. Forty-six percent of women were uncertain about the symptoms of cervical cancer. About half the women recognized cervical infection, smoking, and having multiple sexual partners as risk factors for cervical cancer; however, only 10% recognized early sexual intercourse as a risk factor. Willingness to participate in a future screening program varied significantly according to educational level, employment status, and total family income. Although cervical cancer incidence and mortality are relatively low in Kuwait, they may be underreported in the absence of a screening program. Moreover, lifetime prevalence of having a Pap smear was found to be considerably lower in Kuwait compared with developed countries.

    The running of complex experimental plants in the field of energetic sources involves a strong component of automation. Since they are unique and innovative plants there are not well defined ways to run them. So it is necessary to design the automation each time and then to select the proper resources for the implementation. The plant for the testing of gas turbine components of Sesta is an important example of this type of approach.

    Full Text Available The cervical-vaginal cytology can be interpreted after many classifications, starting from Babeú- Papanicolaou and ending with the Bethesda system, but no matter what the interpretation manner is it is really important to have a good quality of the smears and an experienced cytologist. If we refer to the total number of cases from the lot presented - 16732 cases, the results are satisfactory; 83% smears having normal limits, 10.14% MCB, 2.71% L-SIL, 0.82% H-SIL, 2.77% ASCUS, 0.10% AGC. In Iaúi there are significantly more patients with benign cell changes and L- SIL, while in Buzău there are significantly more patients with a normal smear, but there is also a higher frequency of theatypical squamous cells with an undetermined significance. Classically specialists say that 50-75% of the false negative results are due to the errors made when harvesting the sample. In conclusion we estimate that considering the present conditions in our country where the lack of interest and financial possibilities do not allow an action of detecting the lesions of the cervix organized nationwide, we can still make a selection of the cases with a high risk by making a free Pap smear for all the patients that come to a specialized service, either state or private, provided they respect the protocol of harvesting the cervical secretions, of preparing and reading/interpreting the smears.

    PAP-1 is an in vitro phosphorylation target of the Pim-1 oncogene. Although PAP-1 binds to Pim-1, it is not a substrate for phosphorylation by Pim-1 in vivo. PAP-1 has recently been implicated as the defective gene in RP9, one type of autosomal dominant retinitis pigmentosa (adRP). However, RP9 is a rare disease and only two missense mutations have been described, so the report of a link between PAP-1 and RP9 was tentative. The precise cellular role of PAP-1 was also unknown at that time. We now report that PAP-1 localizes in nuclear speckles containing the splicing factor SC35 and interacts directly with another splicing factor, U2AF35. Furthermore, we used in vitro and in vivo splicing assays to show that PAP-1 has an activity, which alters the pattern of pre-mRNA splicing and that this activity is dependent on the phosphorylation state of PAP-1. We used the same splicing assay to examine the activities of two mutant forms of PAP-1 found in RP9 patients. The results showed that while one of the mutations, H137L, had no effect on splicing activity compared with that of wild-type PAP-1, the other, D170G, resulted in both a defect in splicing activity and a decreased proportion of phosphorylated PAP-1. The D170G mutation may therefore cause RP by altering splicing of retinal genes through a decrease in PAP-1 phosphorylation. These results demonstrate that PAP-1 has a role in pre-mRNA splicing and, given that three other splicing factors have been implicated in adRP, this finding provides compelling further evidence that PAP-1 is indeed the RP9 gene

    Aerosol drug delivery via high flow nasal cannula (HFNC), bubble continuous positive airway pressure (CPAP), and synchronized inspiratory positive airway pressure (SiPAP) has not been quantified in spontaneously breathing premature infants. The purpose of this study was to compare aerosol delivery via HFNC, bubble CPAP, and SiPAP in a model of a simulated spontaneously breathing preterm infant. The types of CPAP systems and nebulizer positions used during aerosol therapy will impact aerosol deposition in simulated spontaneously breathing infants. Quantitative, comparative, in-vitro study. A breath simulator was set to preterm infant settings (VT : 9 ml, RR: 50 bpm and Ti: 0.5 sec) and connected to the trachea of an anatomical upper airway model of a preterm infant via collecting filter distal to the trachea. The HFNC (Optiflow; Fisher & Paykel), Bubble CPAP (Fisher & Paykel), and SiPAP (Carefusion) were attached to the nares of the model via each device's proprietary nasal cannula and set to deliver a baseline of 5 cm H2 O pressure. Albuterol sulfate (2.5 mg/0.5 ml) was aerosolized with a mesh nebulizer (Aeroneb Solo) positioned(1) proximal to the patient and(2) prior to the humidifier (n = 5). The drug was eluted from the filter with 0.1 N HCl and analyzed via spectrophotometry (276 nm). Data were analyzed using descriptive statistics, t-tests, and one-way analysis of variance (ANOVA), with P CPAP (1.24 ± 0.24; p = 0.008). Placement of the nebulizer prior to the humidifier increased deposition with all devices (P < 0.05). Aerosol can be delivered via all three devices used in this study. Device selection and nebulizer position impacted aerosol delivery in this simulated model of a spontaneously breathing preterm infant. © 2014 Wiley Periodicals, Inc.

    Objectives. Reproductive health screenings are a necessary part of quality health care. However, sexual minorities underutilize Papanicolaou (Pap) tests more than heterosexuals do, and the reasons are not known. Our objective was to examine if less hormonal contraceptive use or less positive health beliefs about Pap tests explain sexual orientation disparities in Pap test intention and utilization. Methods. We used multivariable regression with prospective data gathered from 3821 females aged 18 to 25 years in the Growing Up Today Study (GUTS). Results. Among lesbians, less hormonal contraceptive use explained 8.6% of the disparities in Pap test intention and 36.1% of the disparities in Pap test utilization. Less positive health beliefs associated with Pap testing explained 19.1% of the disparities in Pap test intention. Together, less hormonal contraceptive use and less positive health beliefs explained 29.3% of the disparities in Pap test intention and 42.2% of the disparities in Pap test utilization. Conclusions. Hormonal contraceptive use and health beliefs, to a lesser extent, help to explain sexual orientation disparities in intention and receipt of a Pap test, especially among lesbians. PMID:23763393

However the incidence is still too high, especially among elderly women. All guidelines strongly recommend a regular Papanicolaou (Pap testing for young and middle-aged patients. On the other hand, many international professional societies no longer advise screening in women who have undergone hysterectomy, and in women aged 65 years and above, who have a previous history of regular Pap smears. Here we report the case of poorly differentiated CC, involving the pelvic lymph nodes and urinary bladder, occurring in a 79-year-old woman who regularly underwent Pap tests, with no reported cytological abnormalities. In this very rare case, the CC cells, as well as cells from metastatic lymph nodes and cells from urinary specimens, molecularly showed human papilloma virus (HPV-53. With the limitations of a single case, this report brings important information to prevent CC in elderly patients: the utility of molecular tests to increase sensitivity of Pap smears in postmenopausal women; the importance of HPV-53 as one of the four “emergent” genotypes having a possible role in oncogenesis; and the presence of HPV-53 in lymph node metastases from cervical carcinoma, which would support the role of this virus in the maintenance of malignant status.Keywords: old women, molecular tests, cervical cancer screening, HPV-DNA test, HPV genotypingA Letter to the editor has been received and published for this articleCorrigendum for this paper has been published

    Cervical cancer is one of the major causes of deaths due to cancer among women in India. Pap smear is one of the best methods to detect early changes in cervix. However, there is lack of data on awareness level of women about Pap smear and various risk factors for cervical cancer. To study the awareness about various risk factors for cervical cancer, health-seeking behavior and hygienic practices among women and to assess the distress experienced by these women before the Pap smear examination. This cross-sectional study was carried out on women coming for a Pap smear examination in a tertiary teaching hospital in New Delhi. A pretested interview schedule was used to get information after obtaining their informed consent. Fifty-seven percent stated that they did not consult a doctor when they noticed the symptoms the first time. Sixty-one percent did not know what a cervical cancer is and a same percentage of women did not know what a Pap smear examination was. Older age group, Muslim and literate women had higher number of abnormal Pap smear results. Women who reported being stressed in their lives had higher number of abnormal smears as compared to women who claimed to lead a stress free life. Poor hygienic practices among these women from urban areas were also associated with abnormal Pap smear results. The study concluded that factors such as poor awareness, shyness, poor hygiene, and old age could be responsible for abnormal Pap smears and this needs special attention in cancer prevention activities of the government.

    This study focuses on the meanings assigned to practices for cervical cancer prevention among women from low-income neighborhoods in Salvador, Bahia State, Brazil. This was a qualitative study based on content analysis of semi-structured interviews with 15 women 24 to 68 years of age. The results showed high appreciation of the Pap smear test, performed as part of routine gynecological examination (but without the patient necessarily having biomedical knowledge of its role). Besides accessibility and quality of health services, other factors influence the way the women assign meaning to cervical cancer prevention. Moral values associated with sexuality and gender influence risk perception, adoption of preventive practices, and interpretation of cervical cytology results. The ongoing practice of the Pap smear test is part of the construction of femininity, which is associated with maturity and personal responsibility for self care in a context of medicalization of the female body.

    Full Text Available The aim of this study was to determine the nutritional composition of five varieties of pap (cereal product commonly consumed in Maroua, city of the Far-North Region of Cameroon. The proximate composition (moisture, ash, protein, lipid, and crude fibre was determined by standard AOAC methods. Minerals (calcium, magnesium, sodium, potassium, iron, zinc, copper and manganese were determined by atomic absorption spectrophotometry and phosphorus was determined colorimetrically. Amino acid composition was determined by ion-exchange chromatography. All the pap varieties had a very high carbohydrate content (79.47-85.29 g/100 g dry matter. Appreciable levels of phosphorus and potassium were recorded in all the pap varieties (137.5-231.0 mg/100 g dry matter and 198.20-322.22 mg/100 g dry matter, respectively. Consumption of each pap (100 g by children 1-2 year old would meet 9.86-17.46% and 0.08-19.51% of their daily recommended intake respectively for protein and minerals. Leucine and glutamic acid were the most abundant essential amino acids and non-essential amino acids respectively in the pap. Essential amino acids in most of the pap samples met the recommended children requirement of the FAO/WHO/UNU for 1-2 year old children except methionine+cysteine and lysine.

  20. Light and the E3 ubiquitin ligase COP1/SPA control the protein stability of the MYB transcription factors PAP1 and PAP2 involved in anthocyanin accumulation in Arabidopsis.

    Anthocyanins are natural pigments that accumulate only in light-grown and not in dark-grown Arabidopsis plants. Repression of anthocyanin accumulation in darkness requires the CONSTITUTIVELY PHOTOMORPHOGENIC1/SUPPRESSOR OF PHYA-105 (COP1/SPA) ubiquitin ligase, as cop1 and spa mutants produce anthocyanins also in the dark. Here, we show that COP1 and SPA proteins interact with the myeloblastosis (MYB) transcription factors PRODUCTION OF ANTHOCYANIN PIGMENT1 (PAP)1 and PAP2, two members of a small protein family that is required for anthocyanin accumulation and for the expression of structural genes in the anthocyanin biosynthesis pathway. The increased anthocyanin levels in cop1 mutants requires the PAP1 gene family, indicating that COP1 functions upstream of the PAP1 gene family. PAP1 and PAP2 proteins are degraded in the dark and this degradation is dependent on the proteasome and on COP1. Hence, the light requirement for anthocyanin biosynthesis results, at least in part, from the light-mediated stabilization of PAP1 and PAP2. Consistent with this conclusion, moderate overexpression of PAP1 leads to an increase in anthocyanin levels only in the light and not in darkness. Here we show that SPA genes are also required for reducing PAP1 and PAP2 transcript levels in dark-grown seedlings. Taken together, these results indicate that the COP1/SPA complex affects PAP1 and PAP2 both transcriptionally and post-translationally. Thus, our findings have identified mechanisms via which the COP1/SPA complex controls anthocyanin levels in Arabidopsis that may be useful for applications in biotechnology directed towards increasing anthocyanin content in plants. © 2013 The Authors The Plant Journal © 2013 John Wiley & Sons Ltd.

    Full Text Available Background and Objectives: Despite the importance of pap smear in reducing the incidence of cervical cancer and its death, this cancer is still one of the leading causes of death among women around the world. Accordingly, in this study, we aimed to determine the effect of an educational program based on the protection motivation theory on Pap smear screening behavior. Materials and Methods: This quasi-experimental study was conducted on 200 women referring to Fasa health centers, Fasa, Iran. The participants were randomized into experimental and control groups (n=100 per group. The data collection tool, which consisted of demographic data and protection motivation theory constructs, was completed by both groups before and 2 months after the intervention. For the experimental group, the educational program was implemented during 4 sessions using group discussions and educational pamphlets. To analyze the data, chi-square test, independent t-test, and paired t-test were run in SPSS, version 22. Results: After the intervention, the mean scores of protection motivation theory constructs significantly increased in the experimental group compared to the control group (P<0.001. However, no significant difference was noted between the two groups regarding the response efficacy construct at the post-intervention stage (P=0.552. In addition, after the intervention, the rate of conducting Pap smear test significantly incremented in the experimental group (58%. Conclusions: The study results revealed the effectiveness of the educational intervention based on protection motivation theory in promoting Pap smear screening behavior. Therefore, we recommend designing educational interventions based on this theory to promote public health, especially in women.

É importante destacar que, em Arroio do Padre, há um processo incipiente de “agroecologização”, ou seja, as unidades familiares encontram-se nos níveis iniciais da transição agroecológica. Já em São Lourenço do Sul, observou-se que essas mulheres atuam na agroecologia há mais de 40 anos. Estas distintas trajetórias conferem percepções de mundo diferenciadas entre os dois contextos sociais. Enquanto para as interlocutoras de Arroio do Padre a agroecologia pouco interfere em suas escolhas dentro e fora de casa, já para as entrevistadas de São Lourenço do Sul é essencial no repensar das relações estabelecidas no lar e no seu entorno, especialmente nos assuntos que tangem aos mercados e a sua valorização enquanto “agricultora”.

    p-Aminophenol (PAP), a metabolite of acetaminophen, is nephrotoxic. This study investigated PAP-mediated changes as a function of time that occur prior to loss of membrane integrity. Experiments further evaluated the development of oxidative stress by PAP. Renal slices from male Fischer 344 (F344) rats (N = 4-6) were exposed to 0.1, 0.25, and 0.5 mM PAP for 15-120 min under oxygen and constant shaking at 37 o C. Pyruvate-stimulated gluconeogenesis, adenine nucleotide levels, and total glutathione (GSH) levels were diminished in a concentration- and time-dependent manner prior to detection of a rise in lactate dehydrogenase (LDH) leakage. Glutathione disulfide (GSSG) levels were increased by PAP suggesting the induction of oxidative stress. Western blot analysis confirmed a rise in 4-hydroxynonenal (4-HNE)-adducted proteins in tissues exposed to 0.1 and 0.25 mM PAP for 90 min. The appearance of 4-HNE-adducted proteins at the 0.1 mM concentration of PAP occurred prior to development of increased LDH leakage. Pretreatment with 1 mM glutathione (GSH) for 30 min only partially reduced PAP toxicity as LDH values were less severely depleted relative to tissues not pretreated with GSH. In contrast, pretreatment for 15 min with 2 mM ascorbic acid completely protected against PAP toxicity. Further studies showed that ascorbic acid pretreatment prevented PAP-mediated depletion of GSH. In summary, PAP rapidly depletes GSH and adenine nucleotides and inhibits gluconeogenesis prior to a rise in LDH leakage. PAP induces oxidative stress as indicated by an increase in GSSG and 4-HNE-adducted proteins. Ascorbic acid pretreatment prevents PAP toxicity by maintaining GSH status

    Obiettivi: la ricerca dei virus enterici in matrici ambientali, soprattutto nei reflui urbani, risulta di grande interesse sia per la valutazione del rischio di natura virale sia per compiere studi epidemiologici.

    Lo scopo di questo lavoro è stato l’applicazione parallela di diverse tecniche attualmente in uso in virologia clinica a isolati citopatogeni ambientali al fine di ottenere una precisa identificazione degli agenti rilevati.

    Metodi: sono stati analizzati 21 campioni di aerosol, provenienti da impianti di depurazione di reflui civili a fanghi attivi, e risultati citopatogeni in colture di cellule BGM.

    Dopo una nuova semina in “shell vials”, su tre linee cellulari continue per mettere in evidenza eventuali differenze nello spettro di citopatogenicità. Per l’identificazione degli isolati virali, sono state adottate in parallelo: microscopia elettronica, tecniche biomolecolari di amplificazione genica, elettroforesi su gel di poliacrilamide (PAGE, test immunoenzimatici, sieroneutralizzazione.

    Risultati: la semina in “shell vials” ha confermato la
    presenza di particelle virali infettive in tutti i campioni
    tranne uno; inoltre ha permesso di ridurre il
    tempo di comparsa dell’effetto citopatico a 3-4 giorni
    contro i 6-8 giorni necessari seminando in fiasche.
    La microscopia elettronica ha individuato la presenza
    di particelle enterovirus-simili in 18 dei 21
    campioni e di virioni della famiglia Reoviridae in 8.
    La positività dei campioni è stata ottenuta, inoltre,
    con la RT-PCR, per 2 campioni di enterovirus e 2 di
    reovirus e con la PAGE in 6 campioni. Il presente
    studio ha portato ad un’identificazione sufficientemente
    certa di reovirus in 2 campioni e di enterovirus
    in 1 campione.

    Conclusioni: l’identificazione di isolati ambientali si

    Full Text Available Aim: To analyze the cervical cytological abnormalities which are detected in women undergoing Pap screening in a tertiary health care center within Siirt, a southeastern province of Turkey. Material and Method: A total of 3000 women who underwent Pap screening at the study center between January 1, 2009 and December 31, 2009 were recruited for the study. The women who were diagnosed with benign epithelial changes, infectious alterations, as well as atypical squamous cells with undetermined significance (ASC-US, atypical squamous cells of high significance (ASC-H, and low-grade squamous intraepithelial lesion (LSIL were included. Results: Benign epithelial alterations, infectious changes, ASCUS, ASC-H, and LSIL were detected in 83.7%, 15.3%, 0.8%, 0.1% and 0.1% of the Pap smears respectively. A significant correlation was found between the patient age and the histopathological alterations in the Pap smears (r=0.072, p=0.001. Although no correlation could be detected between gravidity and Pap smear results (r=0.033, p=0.067, a significant correlation existed between parity and the histopathological findings within the Pap smears (r=0.051, p=0.005. Interestingly, the Pap smear results were found to be unrelated to socioeconomic status (r=0.088, p=0.168, education level (r=0.048, p=0.257, and smoking habit (r=0.086, p=0.077. Discussion: The present study has reported a value of 1.0% for the overall prevalence of cervical cytological abnormalities, which is much lower than in western countries. Thus, rather than being dependent on the data reported by clinical studies that have been conducted in western countries, Turkish health care policy should be based on the data obtained from national studies.

    Recently, we noticed a considerable development in alleviating problems related to positive airway pressure (PAP) masks. In this study, we report on the initial PAP mask acceptance rates and the effects of mask switching on mask-related symptoms. We prospectively collected all cases of mask switching in our sleep unit for a period of 14 months. At the time of the study, we used ResMed™ CPAP devices and masks. Mask switching was defined as replacing a mask used for at least 1 day with another type of mask. Changing to a different size but keeping the same type of mask did not count as mask switching. Switching outcomes were considered failed if the initial problem persisted or reappeared during the year that followed switching. Our patient pool was 2768. We recorded 343 cases of mask switching among 267 patients. Of the 566 patients who began new PAP therapy, 108 (39 women) had switched masks, yielding an initial mask acceptance rate of 81 %. The reason for switching was poor-fit/uncomfortable mask in 39 %, leak-related in 30 %, outdated model in 25 %, and nasal stuffiness in 6 % of cases; mask switching resolved these problems in 61 %. Mask switching occurred significantly (p = 0.037) more often in women and in new PAP users. The odds ratio for abandoning PAP therapy within 1 year after mask switching was 7.2 times higher (interval 4.7-11.1) than not switching masks. The initial PAP mask acceptance rate was high. Patients who switched their masks are at greater risk for abandoning PAP therapy.

  7. Recombinant mouse PAP has pH-dependent ectonucleotidase activity and acts through A(1-adenosine receptors to mediate antinociception.

    Full Text Available Prostatic acid phosphatase (PAP is expressed in nociceptive neurons and functions as an ectonucleotidase. When injected intraspinally, the secretory isoforms of human and bovine PAP protein have potent and long-lasting antinociceptive effects that are dependent on A(1-adenosine receptor (A(1R activation. In this study, we purified the secretory isoform of mouse (mPAP using the baculovirus expression system to determine if recombinant mPAP also had antinociceptive properties. We found that mPAP dephosphorylated AMP, and to a much lesser extent, ADP at neutral pH (pH 7.0. In contrast, mPAP dephosphorylated all purine nucleotides (AMP, ADP, ATP at an acidic pH (pH 5.6. The transmembrane isoform of mPAP had similar pH-dependent ectonucleotidase activity. A single intraspinal injection of mPAP protein had long-lasting (three day antinociceptive properties, including antihyperalgesic and antiallodynic effects in the Complete Freund's Adjuvant (CFA inflammatory pain model. These antinociceptive effects were transiently blocked by the A(1R antagonist 8-cyclopentyl-1, 3-dipropylxanthine (CPX, suggesting mPAP dephosphorylates nucleotides to adenosine to mediate antinociception just like human and bovine PAP. Our studies indicate that PAP has species-conserved antinociceptive effects and has pH-dependent ectonucleotidase activity. The ability to metabolize nucleotides in a pH-dependent manner could be relevant to conditions like inflammation where tissue acidosis and nucleotide release occur. Lastly, our studies demonstrate that recombinant PAP protein can be used to treat chronic pain in animal models.

    Bricker, Angela L.; Belasco, Joel G.

    1999-01-01

    High-level expression of the major pilus subunit (PapA) of uropathogenic strains of Escherichia coli results in part from the unusually long lifetime of the mRNA that encodes this protein. Here we report that the longevity of papA mRNA derives in large measure from the protection afforded by its 5′ untranslated region. This papA RNA segment can prolong the lifetime of an otherwise short-lived mRNA to which it is fused. In vivo alkylation studies indicate that, in its natural milieu, the papA ...

  10. Factors affecting compliance with clinical practice guidelines for pap smear screening among healthcare providers in africa: systematic review and meta-summary of 2045 individuals.

    Full Text Available Although the importance of the Pap smear in reducing cancer incidence and mortality is known, many countries in Africa have not initiated yet widespread national cervical cancer screening programs. The World Health Organization (WHO has published Clinical Practice Guidelines (CPGs on cervical cancer screening in developing countries; however, there is a gap between expectations and clinical performance. Thus, the aim of this study was to conduct a systematic review and meta-summary to identify factors affecting compliance with CPGs for Pap screening among healthcare providers in Africa.And Findings: MEDLINE, Scirus, Opengate and EMBASE databases were searched in January 2012. Studies involving medical personnel practicing in Africa, whose outcome measured any factors that affect medical personnel from using a Pap smear to screen for cervical cancer, were included. Two reviewers independently evaluated titles and abstracts, then full-texts, extracted data and assessed quality of the included studies. A descriptive analysis of the included studies was conducted. We calculated Frequency effect sizes (FES for each finding and Intensity effect sizes (IES for each article to represent their magnitudes in the analyses. Of 1011 studies retrieved, 11 studies were included (2045 individuals. Six different themes related to the factors affecting compliance with CPGs were identified: Insufficient Knowledge/Lack of awareness (FES = 82%, Negligence/Misbeliefs (FES = 82%, Psychological Reasons (FES = 73%, Time/Cost Constraint (FES = 36%, Insufficient infrastructure/training (FES = 45% and also no reason given (FES = 36%. IES for articles ranged between 33 and 83%.These results suggest that prevention initiatives should be comprehensive to include education and resources needs assessments and improvement, Pap smear test training, strategies on costing, and practitioner time studies.

    Background Almost one million prematurely born infants die annually from respiratory insufficiency, predominantly in countries with limited access to respiratory support for neonates. The primary hypothesis tested in the present study was that a modified device for bubble nasal continuous positive airway pressure (Bn-CPAP) would provide lower work of spontaneous breathing, estimated by esophageal pressure-rate products. Methods Infants born CPAP with FiO2 CPAP, then 2 h with Bn-CPAP using a modified bubble device presently termed Seattle-PAP, which produces a different pattern of pressure fluctuations and which provided greater respiratory support in preclinical studies, then 2 h on standard Bn-CPAP. Results All 40 infants enrolled completed the study and follow-up through 36 wks post menstrual age or hospital discharge, whichever came first. No infants were on supplemental oxygen at completion of follow-up. No infants developed pneumothoraces or nasal trauma, and no adverse events attributed to the study were observed. Pressure-rate products on the two devices were not different, but effort of breathing, assessed by areas under esophageal pressure-time curves, was lower with Seattle-PAP than with standard Bn-CPAP. Conclusion Use of Seattle-PAP to implement Bn-CPAP lowers the effort of breathing exerted even by relatively healthy spontaneously breathing premature neonates. Whether the lower effort of breathing observed with Seattle-PAP translates to improvements in neonatal mortality or morbidity will need to be determined by studies in appropriate patient populations.

    Full Text Available Lo studio delle narrazioni di genere all'interno di questo tipo di organizzazione desta inoltre un particolare interesse anche in ragione della sottorappresentazione delle donne nella sfera della politica. Si tratta di un deficit democratico che coinvolge i sistemi politici moderni nel loro complesso, ma che interessa l'Italia con una particolare gravità ed evidenza. La questione della sottorappresentazione politica delle donne è stata sinora affrontata prevalentemente in termini tecnico-legali (politiche di pari opportunità ed azione positiva, o di teoria politica (la dicotomia pubblico-maschile e privato-femminile come fondamento del contratto sessuale della politica. Mancano invece contributi che guardino ai partiti come organizzazioni largamente responsabili dei processi di selezione e promozione delle carriere politiche, dunque come luoghi di quotidiana produzione di pratiche e culture di genere, più o meno egualitarie o, viceversa, discriminatorie. Sulla base di tale vuoto di ricerca e riflessione, il presente articolo si propone di mettere in luce le pratiche e le culture di genere che emergono dai racconti di uomini e donne all'interno di due organizzazioni partitiche, una di destra e una di sinistra, situate nel contesto territoriale della provincia di Trento. La ricerca è stata condotta attraverso lo strumento dell'intervista semi-strutturata, coinvolgendo quattro donne e quattro uomini, divisi per coppie di età (un uomo ed una donna giovani ed un uomo ed una donna da lungo presenti nel partito, accostabili per quanto concerne ruolo e posizione nelle organizzazioni partitiche considerate.

    While the benefits of continuous positive airway pressure (CPAP) or bilevel positive airway pressure (BiPAP) for patients with obstructive sleep apnea are well described, reports in the literature of complications from its use are rare. A patient who received postoperative BiPAP after undergoing transsphenoidal craniopharyngioma resection developed severe pneumocephalus and unplanned intensive care unit admission. Although the pneumocephalus resolved with conservative management over two weeks, we propose caution in the use of CPAP postoperatively in patients undergoing procedures of the head and neck.

    It is difficult to synthesize the vast amount of textual data available from social media websites. Capturing real-world discussions via social media could provide insights into individuals' opinions and the decision-making process. We conducted a sequential mixed methods study to determine the utility of sparse machine learning techniques in summarizing Twitter dialogues. We chose a narrowly defined topic for this approach: cervical cancer discussions over a 6-month time period surrounding a change in Pap smear screening guidelines. We applied statistical methodologies, known as sparse machine learning algorithms, to summarize Twitter messages about cervical cancer before and after the 2012 change in Pap smear screening guidelines by the US Preventive Services Task Force (USPSTF). All messages containing the search terms "cervical cancer," "Pap smear," and "Pap test" were analyzed during: (1) January 1-March 13, 2012, and (2) March 14-June 30, 2012. Topic modeling was used to discern the most common topics from each time period, and determine the singular value criterion for each topic. The results were then qualitatively coded from top 10 relevant topics to determine the efficiency of clustering method in grouping distinct ideas, and how the discussion differed before vs. after the change in guidelines . This machine learning method was effective in grouping the relevant discussion topics about cervical cancer during the respective time periods (~20% overall irrelevant content in both time periods). Qualitative analysis determined that a significant portion of the top discussion topics in the second time period directly reflected the USPSTF guideline change (eg, "New Screening Guidelines for Cervical Cancer"), and many topics in both time periods were addressing basic screening promotion and education (eg, "It is Cervical Cancer Awareness Month! Click the link to see where you can receive a free or low cost Pap test.") It was demonstrated that machine learning

    Full Text Available Electronic nose and olfactometry techniques represent a modern analytical approach in food industry since they could potentially improve quality and safety of food processing. The aim of this study was to evaluate possible application of electronic nose in PA P detection and recognition in feed. For this purpose 6 reference feedstuffs (CRA-W / UE STRAT F E E D Project were used. The basis of the test samples was a compound feed for bovine fortified with processed animal proteins ( PAP consisting of meat and bone meal (MBM and/or fish meal at different concentrations. Each feed sample was tested in glass vials and the odour profile was determined by the ten MOS (metal oxide semi-conductor sensors of the electronic nose. Ten different descriptors, representing each ten sensors of electronic nose, were used to characterise the odour of each sample. In the present study, electronic nose was able to discriminate the blank sample from all other samples containing PA P ( M B M , fish meal or both. Samples containing either 0.5% of MBM or 5% of fish meal were identified, while samples containing a high fish meal content (5% associated with a low MBM content (0.5% were not discriminated from samples containing solely fish meal at that same high level (5%. This latter indicates that probably the high fish meal level, in samples containing both MBM and fish meal, tended to mask MBM odour. It was also evident that two odour descriptors were enough to explain 72.12% of total variability in odour pattern. In view of these results, it could be suggested that electronic nose and olfactometry techniques can provide an interesting approach for screening raw materials in feed industry, even though further studies using a wider set of samples are needed.

    Cervical cancer is an important woman's health problems worldwide, especially in low socio-economic countries. The aim of this study was to compare the Pap smear screening results between Akha hill tribe and urban women who live in Chiang Rai province, Thailand. Screening was conducted for 1,100 Akha women and 1,100 urban women who came to have the Pap smear at Chiangrai Prachanukroh Hospital and 1 private cytology laboratory from January to June 2008. The demographic characteristics and factors related to abnormal Pap smears of these women were gathered using closed model questionnaires. Abnormal Rap smears were defined according to the Bethesda 2001 system. The results showed that the prevalence of abnormal Pap smears was 12.2% in Akha women and 4.5% in urban women. The highest prevalence of Pap abnormalities was found in the 41-50 years age group in both populations (4.5% in Akha and 1.7% in urban women). In both populations, abnormal Pap smears were found in education level. In conclusion, cervical cancer control by education and early detection by Pap smear screening is necessary for hill tribe women. More Pap smear screening service units should be set to improve the coverage for the risk group women who got married in young age, especial in ethnic groups.

    Full Text Available Abstract Background Others and we have previously described the potent in vivo and in vitro activity of the broad-spectrum antiviral agent PAP (Pokeweed antiviral protein against a wide range of viruses. The purpose of the present study was to further elucidate the anti-viral spectrum of PAP by examining its effects on the survival of mice challenged with lymphocytic choriomeningitis virus (LCMV. Methods We examined the therapeutic effect of PAP in CBA mice inoculated with intracerebral injections of the WE54 strain of LCMV at a 1000 PFU dose level that is lethal to 100% of mice within 7–9 days. Mice were treated either with vehicle or PAP administered intraperitoneally 24 hours prior to, 1 hour prior to and 24 hours, 48 hours 72 hours and 96 hours after virus inoculation. Results PAP exhibits significant in vivo anti- LCMV activity in mice challenged intracerebrally with an otherwise invariably fatal dose of LCMV. At non-toxic dose levels, PAP significantly prolonged survival in the absence of the majority of disease-associated symptoms. The median survival time of PAP-treated mice was >21 days as opposed to 7 days median survival for the control (p = 0.0069. Conclusion Our results presented herein provide unprecedented experimental evidence that PAP exhibits antiviral activity in the CNS of LCMV-infected mice.

  20. Star-PAP Control of BIK Expression and Apoptosis Is Regulated by Nuclear PIPKIα and PKCδ Signaling

    SUMMARY BIK protein is an initiator of mitochondrial apoptosis and BIK expression is induced by pro-apoptotic signals including DNA damage. Here we demonstrate that 3′-end processing and expression of BIK mRNA are controlled by the nuclear PI4,5P2-regulated poly(A) polymerase Star-PAP downstream of DNA damage. Nuclear PKCδ is a key mediator of apoptosis and DNA damage stimulates PKCδ association with the Star-PAP complex where PKCδ is required for Star-PAP-dependent BIK expression. PKCδ binds the PI4,5P2-generating enzyme PIPKIα, which is essential for PKCδ interaction with the Star-PAP complex and PKCδ activity is directly stimulated by PI4,5P2. Features in the BIK 3′-UTR uniquely define Star-PAP specificity and may block canonical PAP activity toward BIK mRNA. This reveals a nuclear phosphoinositide signaling nexus where PIPKIα, PI4,5P2 and PKCδ regulate Star-PAP control of BIK expression and induction of apoptosis. This pathway is distinct from the Star-PAP-mediated oxidative stress pathway indicating signal-specific regulation of mRNA 3′-end processing. PMID:22244330

    2017-06-01

    Full Text Available Background and Objective: Cervical cancer is the second most common cancer among the females. This cancer is considered as a preventable disease due to having a long period before the invasion, availability of appropriate screening program, and effective treatment of primary lesions. The aim of this study was to determine the factors related to per forming regular Pap smear test based on the Theory of Planned Behavior (TPB among the females living in Fasa, Iran. Materials and Methods: This descriptive-analytic cross-sectional study was conducted on 700 married women in Fasa city in 2016. The study population was selected from the females referring to the healthcare centers of Fasa using simple random sampling technique. The data were collected by means of a three-part questionnaire, including demographic data, knowledge, and TPB constructs. Data analysis was performed using Pearson correlation coefficient test and logistic regression in SPSS, version 22. Results: According to the results, 45.7% of the patients had a history of undergoing a Pap smear test, and 20.7% of them performed this test regularly. The results indicated that knowledge, attitude, subjective norms, and perceived behavioral control were the predictors of intention and behavior of Pap smear test among the women (P<0.05. These components accounted for 57.4% and 31.6% of the intention and behavior variance, respectively. Conclusion: As the findings of this study indicated, it is possible to increase the level of screening behaviors among the women by improving their awareness, attitude, subjective norms, and perceived behavioral control. This measure in turn plays a significant role in the prevention and control of cervical cancer.

    2005-01-01

    We have reported that PAP-1, a product of a causative gene for autosomal retinitis pigmentosa, plays a role in splicing. In this study, CIR, a protein originally identified as a CBF1-interacting protein and reported to act as a transcriptional corepressor, was identified as a PAP-1 binding protein and its function as a splicing factor was investigated. In addition to a basic lysine and acidic serine-rich (BA) domain and a zinc knuckle-like motif, CIR has an arginine/serine dipeptide repeat (RS) domain in its C terminal region. The RS domain has been reported to be present in the superfamily of SR proteins, which are involved in splicing reactions. We generated CIR mutants with deletions of each BA and RS domain and studied their subcellular localizations and interactions with PAP-1 and other SR proteins, including SC35, SF2/ASF, and U2AF 35 . CIR was found to interact with U2AF 35 through the BA domain, with SC35 and SF2/ASF through the RS domain, and with PAP-1 outside the BA domain in vivo and in vitro. CIR was found to be colocalized with SC35 and PAP-1 in nuclear speckles. Then the effect of CIR on splicing was investigated using the E1a minigene as a reporter in HeLa cells. Ectopic expression of CIR with the E1a minigene changed the ratio of spliced isoforms of E1a that were produced by alternative selection of 5'-splice sites. These results indicate that CIR is a member of the family of SR-related proteins and that CIR plays a role in splicing regulation

    Invasive cervical cancer is today the fourth most common cancer of women in western civilization. Screening programs have led to a continuously decrease. Nevertheless, both screening and a positive test result are known to be associated with a negative psychological impact. Screening programs in European countries differ and thus psychological impact might as well. The aim of this study was to evaluate the psychological impact of women with an abnormal Pap smear in a German cohort. Between July 2013 and May 2014, a self-assessment questionnaire was distributed to 595 patients that were referred to a special clinic for cervical dysplasia for further evaluation of an abnormal Pap smear. Patients were recruited in five different centers. Most patients (45.9 %) were informed about the test result via phone call by their doctor. 68.8 % of the patients felt anxious and 26.3 % even felt panic. After having talked to their physician, 51.4 % of our cohort still felt worried and only 24.4 % felt reassured. Concerning disease management, 48.4 % underwent a control Pap smear in 6 months. The preferred information source was the physician (63.9 %). Compared to the results in other European countries, our study cohort showed differences concerning age distribution, patients living in a partnership, number of children and especially disease management. Cancer screening itself and abnormal test results have an impact on patient's feelings. To reduce the psychological impact, patients need to be better informed about the risks and benefits of cancer screening programs and in case of cervical cancer screening about the meaning of an abnormal test result. Our results underline the importance of a trustful physician-patient relationship in that matter.

    Full Text Available Our study aimed to assess adult women's knowledge of human papillomavirus (HPV and cervical cancer, and characterize their attitudes towards potential screening and prevention strategies.Women were participants of an HIV-discordant couples cohort in Nairobi, Kenya. An interviewer-administered questionnaire was used to obtain information on sociodemographic status, and sexual and medical history at baseline and on knowledge and attitudes towards Pap smears, self-sampling, and HPV vaccination at study exit.Only 14% of the 409 women (67% HIV-positive; median age 29 years had ever had a Pap smear prior to study enrollment and very few women had ever heard of HPV (18%. Although most women knew that Pap smears detect cervical cancer (69%, very few knew that routine Pap screening is the main way to prevent ICC (18%. Most women reported a high level of cultural acceptability for Pap smear screening and a low level of physical discomfort during Pap smear collection. In addition, over 80% of women reported that they would feel comfortable using a self-sampling device (82% and would prefer at-home sample collection (84%. Nearly all women (94% reported willingness to be vaccinated to prevent cervical cancer if offered at no or low cost.These findings highlight the need to educate women on routine use of Pap smears in the prevention of cervical cancer and demonstrate that vaccination and self-sampling would be acceptable modalities for cervical cancer prevention and screening.

    Zooplankton behaviour depending on light, such as phototaxis, is important, mainly in terms of its ecological significance, as, for example, in the role of phototaxis in the diurnal vertical migration of Daphnia magna, and its possible involvement in predator-prey relations. In Daphnia magna chemicals were found to induce roughly three types of phototaxis alteration: depression, enhancement and sign change. These phenomena are based on mechanisms that require further investigation. In spite of the complex photobehaviour of Daphnia magna and the scarce knowledge of toxic effects, it was possible to set up rapid and easy ecotoxicity tests by fixing certain experimental conditions.

    KEY MESSAGE : pap1 - D/fls1ko double mutant plants that produce substantial amounts of anthocyanin show tolerance to abiotic stress. Anthocyanins are flavonoids that are abundant in various plants and have beneficial effects on both plants and humans. Many genes in flavonoid biosynthetic pathways have been identified, including those in the MYB-bHLH-WD40 (MBW) complex. The MYB gene Production of Anthocyanin Pigment 1 (PAP1) plays a particularly important role in anthocyanin accumulation. PAP1 expression in many plant systems strongly increases anthocyanin levels, resulting in a dark purple color in many plant organs. In this study, we generated double mutant plants that harbor fls1ko in the pap1-D background (i.e., pap1-D/fls1ko plants), to examine whether anthocyanins can be further enhanced by blocking flavonol biosynthesis under PAP1 overexpression. We also wanted to examine whether the increased anthocyanin levels contribute to defense against osmotic stresses. The pap1-D/fls1ko mutants accumulated higher anthocyanin levels than pap1-D plants in both control and sucrose-treated conditions. However, flavonoid biosynthesis genes were slightly down-regulated in the pap1-D/fls1ko seedlings as compared to their expression in pap1-D seedlings. We also report the performance of pap1-D/fls1ko seedlings in response to plant osmotic stresses.

    This study developed a new purple coloured Taraxacum brevicorniculatum plant through genetic transformation using the Arabidopsis AtPAP1 gene, which overproduced anthocyanins in its vegetative tissues. Rubber-producing Taraxacum plants synthesise high-quality natural rubber (NR) in their roots and so are a promising alternative global source of this raw material. A major factor in its commercialization is the need for multipurpose exploitation of the whole plant. To add value to the aerial tissues, red/purple plants of the rubber-producing Taraxacum brevicorniculatum species were developed through heterologous expression of the production of anthocyanin pigment 1 (AtPAP1) transcription factor from Arabidopsis thaliana. The vegetative tissue of the transgenic plants showed an average of a 48-fold increase in total anthocyanin content over control levels, but with the exception of pigmentation, the transgenic plants were phenotypically comparable to controls and displayed similar growth vigor. Southern blot analysis confirmed that the AtPAP1 gene had been integrated into the genome of the high anthocyanin Taraxacum plants. The AtPAP1 expression levels were estimated by quantitative real-time PCR and were highly correlated with the levels of total anthocyanins in five independent transgenic lines. High levels of three cyanidin glycosides found in the purple plants were characterized by high performance liquid chromatography-mass spectrum analysis. The presence of NR was verified by NMR and infrared spectroscopy, and confirmed that NR biosynthesis had not been affected in the transgenic Taraxacum lines. In addition, other major phenylpropanoid products such as chlorogenic acid and quercetin glycosides were also enhanced in the transgenic Taraxacum. The red/purple transgenic Taraxacum lines described in this study would increase the future application of the species as a rubber-producing crop due to its additional health benefits.

    Reliable laboratory testing is of great importance to detect Bartonella bacilliformis infection. We evaluated the sensitivity and specificity of the enzyme-linked immunosorbent assay (ELISA) using recombinant protein Pap31 (rPap31) for the detection of antibodies against B. bacilliformis as compared with immunofluorescent assay (IFA). Of the 302 sera collected between 1997 and 2000 among an at-risk Peruvian population, 103 and 34 samples tested positive for IFA-immunoglobulin G (IgG) and IFA-IgM, respectively. By using Youden's index, the cutoff values of ELISA-IgG at 0.915 gave a sensitivity of 84.5% and specificity of 94%. The cutoff values of ELISA-IgM at 0.634 gave a sensitivity of 88.2% and specificity of 85.1%. Using latent class analysis, estimates of sensitivity and specificity of almost all the assays were slightly higher than those of a conventional method of calculation. The test is proved beneficial for discriminating between infected and non-infected individuals with the advantage of low-cost and high-throughput capability. PMID:24515944

    Full Text Available Abstract Background Extensive information on cervical cancer is currently available. Its effectiveness in reducing anxiety in women receiving abnormal Pap tests is not clear. We investigated current practices of communicating abnormal Pap results to evaluate women's reactions and determine the sources of information they use subsequently. Methods A self-administered questionnaire-based study was performed in 1475 women in France, Spain and Portugal who had received an abnormal Pap smear result in the 12 months prior to completing the questionnaire. Questions covered methods of communication of the result, emotional reactions, support received (from the physician and entourage, and information sources, using pre-specified check box options and rating scales. Data were analyzed by country. Results Pap test results were mostly communicated by phone to Spanish women (76%, while physician letters were common in France (59% and Portugal (36%. Frequent reactions were anxiety, panic and stress, which were less common in Spanish women than their French and Portuguese counterparts. After discussing with their physician, half of the participants were worried, despite rating highly the psychological support received. Over 90% of women in each country discussed their results with family or friends. Partners provided a high level of support. Overall, the abnormal diagnosis and consequences had a low to medium impact on daily, professional and family life and their relationships with their partner. Impact was higher in Spanish women than the French or Portuguese. Information on the diagnosis and its treatment was rated average, and nearly 80% of participants wanted more information, notably French women. Preferred sources were the physician and the Internet. Conclusions Women expressed a strong wish for more information about cervical cancer and other HPV-related diseases, and that their physician play a major role in its provision and in support.

    Mi'kmaq women are reported to have lower rates of Papanicolaou (Pap) screening and higher rates of cervical cancer than non-Aboriginal women. This qualitative participatory study used postcolonial feminist perspectives and Indigenous principles to explore Mi'kmaq women's experiences with Pap screening within the contexts that shaped their experiences. Community facilitators assisted with the research process. Talking circles and individual in-depth interviews were conducted with 16 Mi'kmaq women. Also, health-care providers were interviewed in 2 Mi'kmaq communities. The findings indicate that historical and social contexts are shaping Mi'kmaq women's screening experiences and that these experiences are diverse, as are their understandings about screening. Some women were accessing regular screening despite challenging personal circumstances. The results highlight the need for nurses and other health-care providers to understand the uniqueness of each woman's experiences with Pap screening. Improvements in screening rates depend on multifaceted nursing approaches developed in partnership with Mi'kmaq women. Copyright© by Ingram School of Nursing, McGill University.

    Full Text Available BACKGROUND Cancer of cervix is a global health problem and is a leading cause of morbidity and mortality of women in India. It is one of the most preventable and curable of all cancers. Simple, noninvasive screening procedures like Papanicolaou smears can help in detection and quick and effective timely treatment. The objective of the study is to assess the role of Pap smear in detecting premalignant, malignant and nonneoplastic lesions of cervix in our institute. MATERIALS AND METHODS This is a one year prospective and four year retrospective study of 1,349 women in age group of 20-80 years carried over a period of 5 years from January 2012-December 2016 in the cytology wing of Department of Pathology, Tripura Medical College. Patients clinically presenting with dyspareunia, postcoital bleeding, vaginal bleeding, frothy vaginal discharge with itching and pain in hypogastrium were included in the study. Samples were collected under direct vision of Cusco’s speculum and transferred to glass slides, fixed and stained by Papanicolaou stain and were examined and reported. Reporting was done as per Bethesda system. RESULTS A total of 1,349 number of cases were screened, out of which 639 number of patients had abnormal Pap smears and 13.63% had unsatisfactory or inadequate samples. LSIL was the most common premalignant lesion with 113 (8.37% number of cases, SCC in 39 (5.2% number of cases, ASCUS in 15 (1.11% and adenocarcinoma in 2 (0.14% number of cases. CONCLUSION It was found that premalignant and malignant lesion in cervix is not uncommon in our setup and Pap smear appears to be an elementary, economical, safe and yet highly sensitive screening test for early detection of various cervical lesions.

La alta prevalencia de incontinencia urinaria de mujeres que solicitaron un examen de indicios de cáncer de cuello uterino justifica aproximaciones preventivas en esos espacios.This cross-sectional study aimed to investigate the association between socio-demographic and behavioral factors and the presence of self-reported urinary incontinence in 784 women undergoing cervical cancer screening in Greater Florianópolis, Santa Catarina State, Brazil. Socio-demographic data, health status, physical activity, constipation, and body mass index were obtained, and the International Consultation on Incontinence Questionnaire-SF was used. Prevalence of urinary incontinence was 30.7% (16.5% reported leakage once a week or less and 23.8% losses in small volumes. Poisson univariate regression showed the following factors associated with urinary incontinence: lower education, lower income, non-white skin color, overweight, worse health status, constipation, and older age. After adjustment, according to a hierarchical model, schooling, ethnicity, health status, and age remained significantly associated. The high prevalence of urinary incontinence in women seeking Pap smear tests justifies preventive approaches in these areas of intervention.

    L’introduzione delle lauree triennali ha in molti casi costretto i docenti a ridurre drasticamente il numero di ore di insegnamento e quindi l’estensione dei programmi dei corsi di Fisica. In questo volumetto l'autore si è proposto di esporre sinteticamente ma con il massimo rigore possibile il corso di Fisica Generale I evitando le dimostrazioni delle leggi fisiche, ma dando la priorità alle applicazioni di tali leggi e allo svolgimento di esercizi che in genere viene trascurato in molti corsi. Ha cercato pertanto di presentare i fenomeni fisici sottolineando, dove possibile, la loro presenza nella vita quotidiana e le loro più semplici e immediate applicazioni, consentendo in tal modo agli studenti di vedere la Fisica non più come una interminabile serie di formule ma come un nuovo modo di interpretare e di capire i fenomeni naturali inanimati (del resto non dobbiamo dimenticare che il termine greco da cui deriva il suo nome è fisis, fisis, ovvero natura).

  10. Genome-Wide Analysis of PAPS1-Dependent Polyadenylation Identifies Novel Roles for Functionally Specialized Poly(A Polymerases in Arabidopsis thaliana.

    Directory of Open Access Journals (Sweden)

    Christian Kappel

    2015-08-01

    Full Text Available The poly(A tail at 3' ends of eukaryotic mRNAs promotes their nuclear export, stability and translational efficiency, and changes in its length can strongly impact gene expression. The Arabidopsis thaliana genome encodes three canonical nuclear poly(A polymerases, PAPS1, PAPS2 and PAPS4. As shown by their different mutant phenotypes, these three isoforms are functionally specialized, with PAPS1 modifying organ growth and suppressing a constitutive immune response. However, the molecular basis of this specialization is largely unknown. Here, we have estimated poly(A-tail lengths on a transcriptome-wide scale in wild-type and paps1 mutants. This identified categories of genes as particularly strongly affected in paps1 mutants, including genes encoding ribosomal proteins, cell-division factors and major carbohydrate-metabolic proteins. We experimentally verified two novel functions of PAPS1 in ribosome biogenesis and redox homoeostasis that were predicted based on the analysis of poly(A-tail length changes in paps1 mutants. When overlaying the PAPS1-dependent effects observed here with coexpression analysis based on independent microarray data, the two clusters of transcripts that are most closely coexpressed with PAPS1 show the strongest change in poly(A-tail length and transcript abundance in paps1 mutants in our analysis. This suggests that their coexpression reflects at least partly the preferential polyadenylation of these transcripts by PAPS1 versus the other two poly(A-polymerase isoforms. Thus, transcriptome-wide analysis of poly(A-tail lengths identifies novel biological functions and likely target transcripts for polyadenylation by PAPS1. Data integration with large-scale co-expression data suggests that changes in the relative activities of the isoforms are used as an endogenous mechanism to co-ordinately modulate plant gene expression.

    Relativamente poco noto al gran pubblico, il premio Nobel Paul Adrien Maurice Dirac appartiene a quel gruppo di uomini di ingegno che nei primi decenni del secolo contribuirono a dare alla nostra concezione del mondo fisico la sua impronta attuale. Assolutamente cruciali, per una valutazione dell'opera di Dirac, sono gli anni compresi tra il 1925 e il 1931: un periodo in cui il fisico fornisce la prima spiegazione chiara e coerente delle proprietà di spin dell'elettrone (equazione di Dirac) e perviene, in forza della pura deduzione matematica, alla scoperta dell'esistenza dell'elettrone positivo o positrone.

    Full Text Available Il contributo proposto ha l’obiettivo di analizzare alcuni significativi brani del tessuto urbano della periferia est di Roma, adottando metodi interpretativi legati alla storia, alla società, alla programmazione urbanistica e alla costruzione. Gli aspetti salienti del quadrante orientale della periferia romana verranno così delineati partendo “dal di dentro”, sottolineandone i percorsi, gli spazi e i nuclei compositivi che sono all’origine della struttura e della forma stessa dei quartieri disposti a cavallo del Grande Raccordo Anulare. In questo ambito, si pone l’attenzione su alcuni episodi chiave che vedono protagoniste le nuove chiese che riescono a creare una centralità all’interno dei quartieri periferici sostituendo le biblioteche, le piazze e i centri commerciali.  Analizzando da vicino questi esempi, si scopre come di recente sono state realizzate chiese firmate da architetti di fama internazionale proprio allo scopo di rafforzare, o meglio di costruire, un fattore identitario per ciascun quartiere ubicato nel settore orientale della città. Partendo quindi dal generale si arriva a indagare una chiesa e un quartiere che possono essere considerati un modello da seguire per tutta la periferia a ridosso del GRA: la chiesa giubilare di Dio Padre Misericordioso progettata da Richard Meier nel quartiere di Tor Tre Teste. La sequenzialità degli eventi che hanno contraddistinto il concorso per la progettazione della chiesa, la scelta della proposta di Richard Meier, la complessità del cantiere, l’analisi tecnica, stilistica e simbolica della realizzazione finale sono quindi analizzate nell’ambito del rapporto con il quartiere e del tentativo di realizzare (attraverso di essa un centro di attrazione per tutta la periferia.   The article analyses some significant parts of the urban tissue at the eastern periphery of Rome, using the interpretative methods inherent to history, society, urban programming and construction

    The assembly of adhesive pili in Gram-negative bacteria is modulated by specialized periplasmic chaperone systems. PapD is the prototype member of the superfamily of periplasmic pilus chaperones. Previously, the alignment of chaperone sequences superimposed on the three dimensional structure of PapD revealed the presence of invariant, conserved and variable amino acids. Representative residues that protruded into the PapD cleft were targeted for site directed mutagenesis to investigate the pi...

    Questa non è solo un'autobiografia scientifica. Il ritratto che Max Born ci offre di se stesso va oltre il profilo dell'uomo di scienza, che pure è stato tra i maggiori del nostro secolo. Di lui veniamo a sapere tutto ciò che occorre per accostarsi alle teorie che gli valsero il premio Nobel, ma anche i tratti di una normale vita borghese nella quale si intrecciavano le influenze dell'ambiente intellettuale e commerciale. Il tono è quello di una rievocazione piana e distesa che ci accompagna per le varie fasi della carriera dello studente, del docente, dello scienziato, nelle università tedesche e inglesi, negli anni delle persecuzioni naziste, alle quali l'ebreo Max Born ebbe la fortuna di sopravvivere, e nel dopoguerra, quando egli tornò in Germania e seppe dare un contributo di idee e di iniziative ai movimenti pacifisti. E' la lunga e operosa vita di un uomo di genio, del quale si ricorda la profonda umanità, la vastità degli interessi culturali, l'acutezza dei giudizi sulle persone, sulle vicend...

    "Introduzione alle Teorie di Gauge" completa la serie di tre volumi basati sulle lezioni dei corsi di Meccanica Quantistica Relativistica, Interazioni Elettrodeboli e Teorie di Gauge, impartite dagli autori agli studenti delle Lauree Magistrali in Fisica e Astronomia & Astrofisica dell'Universita "La Sapienza" di Roma, nell'arco di qualche decennio. L'obiettivo principale del volume è di introdurre i concetti di base della rinormalizzazione nella teoria quantistica dei campi e i fondamenti delle moderne teorie di Gauge. Anche se collegato ai volumi precedenti, il libro si presta ad una lettura indipendente, che presume solo conoscenze generali di relativita speciale, della seconda quantizzazione e della fenomenologia delle interazioni elettrodeboli. Lo strumento di base è l'integrale sui cammini di Feynman, introdotto nei capitoli iniziali e sistematicamente impiegato nel seguito. L'esposizione segue un percorso pedagogico, che parte dal caso semplice dell'ampiezza di transizione in meccanica quantistic...

  2. OTTO-PAP: An alternative option to the PBMR fuelling philosophy

    International Nuclear Information System (INIS)

    Mulder, E.; Teuchert, E.

    1997-01-01

    Once Through Then Out, Power Adjusted by Poison (OTTO-PAP) fuelling of a high temperature pebble-bed reactor offers a simple alternative to the MEDUL (Mehrfachdurchlauf = German for multi-pass) fuelling regime followed in pebble bed reactor designs to date. The prerequisite for a modular reactor unit of maximum power output, subject to observing passive safety characteristics is a sufficiently flat axial neutron flux profile. This is achieved by introducing B 4 C coated particles of pre-calculated size and packing density within the fuel spheres. In accordance with AVR operating practise the temperature profile is radially equalised by introducing a 2-zone core loading. Adding pure graphite spheres loosely into the centre column area of the core effectively reduced the maximum power in the middle. Increasing the reactor diameter is enabled by the introduction of noses. A 3-D geometric modeller developed in cylindrical co-ordinates enables a given flow description of the pebbles adjacent to the nose boundaries and in the vicinity of the shut down/control rods. After translation of the geometric data the neutronic behaviour of the reactor is followed in 3-D by the CITATION code. This study is aimed towards achieving an optimal core layout with a LEU (Low Enriched Uranium) fuel cycle. Physical properties of the OTTO-PAP, 150 MWt reference design is reported, while computations performed observe results obtained by the reference HTR-MODUL design. (author)

    The levonorgestrel intrauterine system (LNG-IUS) combines a uterine foreign body and the continuous release of low-dose levonorgestrel for contraception. Its influence on the rate of vulvovaginal infections and flora disturbance is insufficiently known, but important for contraceptive advice in women, especially those who develop recurrent vaginosis or Candida vulvovaginitis. Slides of 286 women who had a Pap smear taken before and 1 to 2 years after placement of a LNG-IUS were blindly reviewed for the presence of abnormal vaginal flora (AVF), bacterial vaginosis (BV), aerobic vaginitis (AV) and Candida vaginitis (CV). Prior to insertion, there were no differences in vaginal flora abnormalities between women using different kinds of contraception. LNG-IUS users did not have different rates of AVF, BV, AV or CV, but the general risk to develop any infection was increased. Uterine bleeding after insertion did not seem to predict a different flora type. We found that Pap smears suggested more vaginal infections after 1 year of LNG-IUS use than prior to insertion of the device. Copyright © 2011 Elsevier Inc. All rights reserved.

    2015-01-01

    This article describes translational research (TR) and continuous quality improvement (CQI) processes used to identify and address barriers and facilitators to Pap smear screening within an urban Aboriginal Community Controlled Health Service (ACCHS). Rapid Plan-Do-Study-Act (PDSA) cycles were conducted, informed by client surveys, a data collection tool, focus groups and internal research. There was a statistically significant increase in Pap smear numbers during PDSA cycles, continuing at 10 months follow up. The use of TR with CQI appears to be an effective and acceptable way to affect Pap smear screening. Community and service collaboration should be at the core of research in Aboriginal and Torres Strait Islander health settings. This model is transferrable to other settings and other health issues.

Questi fattori sono stati responsabili anche di un impoverimento genetico della forma autoctona italiana Sus scrofa meridionalis e majori che sembrano persistere solo in Sardegna e Maremma (Apollonio et al., 1988. Tra le riserve in cui si ritiene possano trovarsi popolazioni ancora integre, figura la tenuta presidenziale di Castelporziano (Roma. Prendendo spunto da questo lavoro, con il nostro contributo riportiamo i risultati, a livello genetico, della ibridazione con il maiale da parte di cinghiali della Campania, basato sul DNA microsatellite di 4 loci polimorfi. Sono state studiate 9 popolazioni (allevate e libere, usando per riferimenti maiali allo stato brado e cinghiali di Castelporziano. Dall?analisi delle frequenze alleliche è stato eseguito il test di assignment (implementato in una sub routine del software Arlequin 2.0 che individua la possibile origine di un individuo, rispetto ad una rosa di probabili popolazioni di riferimento (Paetkau et al., 1998. Con i risultati del test di assignment si è costruito il grafico log-log genotype, rappresentato da un piano individuato dalle due variabili di riferimento (cinghiale e maiale brado. Le popolazioni esaminate evidenziano una generalizzata distribuzione a cavallo tra i due riferimenti con individui geneticamente simili al cinghiale ed altri al maiale. Questa ripartizione simmetrica è molto evidente nel caso dei cinghiali catturati a Punta Licosa e in quelli dell?allevamento di Polla. La distribuzione dei genotipi sul piano è spesso dispersa, ad eccezione dei cinghiali della Valle del Vento e quelli di Monteverde (individui

    Obiettivi: aumento del 10% dell’uso delle cinture di sicurezza anteriori e posteriori e del 20% dei seggiolini per bambini nella Regione del Veneto.

    Metodi: il Programma Regionale di Prevenzione dei Traumi da Traffico è stato varato nel 1998 e rifinanziato nel 2002 per un secondo triennio. Fa capo alla Direzione per la Prevenzione dell’Assessorato alle Politiche Sanitarie del Veneto, coinvolge i Dipartimenti di Prevenzione di tutte le Aziende ULSS del Veneto e ha come capofila l’azienda ULSS 7 di Pieve di Soligo (TV. Nell’ambito del programma, il 16 maggio 2003 è stata avviata una campagna di marketing sociale finanziata dalla fondazione CARIVERONA e commissionata ad un’ agenzia pubblicitaria leader del settore. La campagna è stata preceduta da ricerca formativa con 19 focus group e 12 interviste, volta ad analizzare il punto di vista dei diversi target, nonché degli attori principali coinvolti (Forze dell’Ordine, autoscuole, etc. Dopo un test di gradimento, la campagna è partita con spot televisivi e radiofonici, inserzioni nei giornali e manifesti informativi destinati alle scuole medie superiori, alle scuole guida nonché agli ambulatori dei medici di famiglia. Attraverso i media si sostiene una serie di azioni nel territorio che coinvolgeranno le amministrazioni comunali, le forze di polizia e le associazioni di volontariato.

    Risultati: l’efficacia della campagna viene valutata attraverso due distinte rilevazioni dell’uso delle cinture di sicurezza/seggiolini, confrontando i dati raccolti prima della campagna e dopo.

    Conclusioni: i traumi da traffico rappresentano nel Veneto un’importante causa di mortalità e morbosità. Il programma regionale ha utilizzato la tecnica innovativa del marketing sociale come strumento essenziale per sostenere i cambiamenti comportamentali necessari a prevenire l’incidentalità da traffico nel

    Introduzione: la complessità interpretativa dei dati relativi ad alcuni fenomeni sanitari a livello territoriale impone la necessità di uno strumento semplice di lettura “epidemiologica”; tale lettura si fonda sull’utilizzo di una serie di “indicatori”, fondamenta di un processo dinamico di monitoraggio temporale e spaziale in grado di descrivere sinteticamente fenomeni di per sé complessi, al fine di fornire al decisore un supporto sintetico ma scientificamente solido.

    Obiettivi: istituzione di un sistema di monitoraggio sanitario community-based; definizione di indicatori sanitari comparabili tramite un esame critico dei dati esistenti; sviluppo di metodologie per la raccolta e la validazione dei dati; supporto alla creazione di un sistema efficace e affidabile di trasferimento e scambio dei dati e degli indicatori stessi con uso spinto della tecnologia telematica; elaborazione di metodi e di strumenti necessari alla produzione di analisi e relazioni.

    Materiali e metodi: gli indicatori analizzati fanno riferimento
    all’elenco definito dal decreto ministeriale n. 27 del 12 dicembre 2001 “sistema di garanzie per il monitoraggio dell’assistenza sanitaria”. A questo elenco ne sono stati aggiunti altri, per un totale di 127, divisi in grandi capitoli tematici: assistenza sanitaria, assistenza distrettuale, assistenza ospedaliera, indicatori stato di salute, consumo di risorse sanitarie (cui è stato dato particolare enfasi, indicatori di domanda/accessibilità. Per definire infine un
    profilo di sintesi di questi grandi capitoli e delle relative
    eterogeneità territoriali si è successivamente applicata la tecnica statistica dello “z-score”.
    Risultati: le differenze emerse a livello distrettuale hanno permesso di disegnare una ‘mappa’ degli indicatori sanitari in provincia di Bergamo.

    Full Text Available Objective: Pap smear test is a major screening test for early diagnosis and treatment of cervix cancer. The aim of our study was to assess the value of HPV-DNA, colposcopy and histopathologic examination in the management of patients with abnormal cervical cytology. Materials and methods: This prospective cohort study was conducted in Ankara University Cebeci Hospital gynecology outpatient clinic. The study compremised 86 patients with smear results of ASCUS, AGC, L-SIL and H-SIL. Age, gravity, parity, age at first coitus, smoking status, number of partners, high risk HPV-DNA status and pathologic colposcopy findings were investigated. Results: Mean age of the patients was 35 years and the most common abnormal smear result was ASCUS, with 55 patients (63%. There was no significant difference between the groups regarding demographic characteristics except age at first coitus and pathologic colposcopy findings. Among patients diagnosed as ASCUS 34.5% had been up-graded with histopathologic examination. Among patients diagnosed as L-SIL 73.6% had been down-graded with histopathologic examination. However, after the histopathologic exam of 9 H-SIL patients two (22.2% were diagnosed as CIN II, two (22.2% were diagnosed as CIN III and one (11.1% was diagnosed as cervical cancer. In the groups of ASCUS, L-SIL and H-SIL the presence of high risk HPV-DNA were 11%, 5% and 33%, respectively. Conclusion: If we are sure that the patient will attend the follow-up visits, then fort he ones with ASCUS and L-SIL a repeat smear test would be the appropriate. However, in the management of patients with H-SIL colposcopic biopsy would be the best approach.

    Full Text Available Abstract Background Although female sex workers (FSWs are a well-known high-risk group for Human Papillomavirus (HPV infections, few tailored intervention programmes for HPV have been established worldwide. The lack of reliable data on the prevalence of HPV and related cervical lesions hampers the establishment of evidence-based intervention programmes. The objectives of this study were to describe the prevalence of high-risk Human Papillomavirus (hrHPV infections and abnormal pap smears in FSWs compared to a control group in Antwerp, Belgium. Methods HPV genotyping and cytology data were analysed from routine Pap smear tests that were collected from both FSWs and the general population (1334 samples for each group between June 2006 and June 2010. Within the laboratory database, all FSWs were matched 1:1 for age and testing date to determine the ORs of hrHPV genotypes, DNA and cytology outcome. Results The prevalence of hrHPV DNA in FSWs was 41.7 % compared to 19.8 % in the age-matched controls with an overall OR of 2.8 (95 % CI: 2.3–3.4. Significant differences were observed in all age groups, and the most significant differences were observed in the cohort under 21 years of age (prevalence of 64.4 % in FSWs versus 14.8 % in controls; OR 10.3 (95 % CI: 5.0–21.2. Significantly more cervical lesions were observed in FSWs, particularly in the 17- to 21-year old age group (OR for LSIL or HSIL: 10.3 (95 % CI: 3.2–33.8. In both groups, HPV 16 was the most prevalent at 12.1 and 6.6 % in the FSW and control groups, respectively. HPV 18 was the 8th and 7th most frequent genotype at 5.0 and 2.5 % in the FSW and control groups, respectively. Conclusions FSWs have a significantly higher prevalence of hrHPV and more abnormal Pap smears than does the general population in Antwerp, Belgium. The hrHPV prevalence in FSWs is similar to that reported in the literature. The need for tailored intervention programmes should be investigated further.

    Primary cervicovaginal melanoma is a rare malignancy associated with a high risk of recurrence. Prior studies discussing the cytomorphology of cervicovaginal melanoma have been based primarily on review of conventional Papanicolaou (Pap) smears. The aim of this study was to evaluate cervicovaginal melanomas identified in liquid-based Pap tests, in comparison with features seen on conventional Pap smear preparation. Cases of cervicovaginal melanoma identified on Pap tests with concurrent or subsequent histopathologic confirmation were collected from the Baystate Medical Center cytopathology files and personal archives of the authors over a total period of 34 years. All cytopathology (n = 6) and the available histology slides (n = 5) were reviewed. Cases were analyzed regarding clinical, histopathologic and cytomorphological findings. A total of six cases with invasive cervicovaginal melanoma diagnosed on Pap tests were identified. Most patients were postmenopausal with contact bleeding, correlating with surface ulceration (identified in biopsy/excision material in 5/5 cases). Most cases had deeply invasive tumors (5/5: modified Breslow's thickness > 5 mm and Chung's level of invasion IV/V). Pap tests included four ThinPrep and two conventional smears. Overall, ThinPrep Pap tests exhibited a higher ratio of tumor cells to background squamous cells. While all Pap tests were bloodstained, tumor diathesis was prominent only within conventional smears. Melanoma cells were present both as clusters and scattered single cells in each Pap test type. Both the preparations contained epithelioid tumor cells, whereas spindled tumor cells were seen in only two ThinPrep cases. Prominent nucleoli and binucleation of tumor cells were seen in both the preparations. Melanin pigment was identified in only ThinPrep (3/4) cases and nuclear pseudo-inclusions in one conventional Pap smear. Cell blocks were made in three ThinPrep cases and immunocytochemistry (S-100, HMB45, Melan

    Full Text Available To improve the production of chlorogenic acid (CGA in hairy roots of Platycodon grandiflorum, we induced over-expression of Arabidopsis thaliana transcription factor production of anthocyanin pigment (AtPAP1 using an Agrobacterium rhizogenes-mediated transformation system. Twelve hairy root lines showing over-expression of AtPAP1 were generated. In order to investigate the regulation of AtPAP1 on the activities of CGA biosynthetic genes, the expression levels of seven P. grandiflorum CGA biosynthetic genes were analyzed in the hairy root line that had the greatest accumulation of AtPAP1 transcript, OxPAP1-1. The introduction of AtPAP1 increased the mRNA levels of all examined CGA biosynthetic genes and resulted in a 900% up-regulation of CGA accumulation in OxPAP1-1 hairy roots relative to controls. This suggests that P. grandiflorum hairy roots that over-express the AtPAP1 gene are a potential alternative source of roots for the production of CGA.

    In patients with infection and sepsis serum levels of Pancreatic Stone protein/regenerating protein I (PSP) are highly elevated. The origin of PSP during these conditions is presumably the pancreas, however, an intestinal origin cannot be excluded. Similarly, pancreatitis-associated protein (PAP) was identified in the pancreas. These proteins were also localized in intestinal organs. Here we aim to elucidate the bio-distribution of PSP and PAP in animal models of sepsis and in healthy humans. PSP and PAP responded to remote lesions in rats although the pancreatic response was much more pronounced than the intestinal. Tissue distribution of PSP demonstrated a 100-fold higher content in the pancreas compared to any other organ while PAP was most abundant in the small intestine. Both proteins responded to CLP or sham operation in the pancreas. PSP also increased in the intestine during CLP. The distribution of PSP and PAP in human tissue mirrored the distribution in the murine models. Distribution of PSP and PAP was visualized by immunohistochemistry. Rats and mice underwent midline laparotomies followed by mobilization of tissue and incision of the pancreatic duct or duodenum. Standard cecum-ligation-puncture (CLP) procedures or sham laparotomies were performed. Human tissue extracts were analyzed for PSP and PAP. The pancreas reacts to remote lesions and septic insults in mice and rats with increased PSP synthesis, while PAP is selectively responsive to septic events. Furthermore, our results suggest that serum PSP in septic patients is predominantly derived through an acute phase response of the pancreas.

    Le idee e le tecniche della Fisica Teorica del XX secolo (meccanica analitica, meccanica statistica, relatività e meccanica quantistica non relativistica) non sono più appannaggio esclusivo dei fisici. Ormai, specialmente con la recente introduzione di nuovi corsi di laurea, le conoscenze di base rientrano nel bagaglio culturale comune ai laureati in materie scientifiche e tecnologiche affini alla Fisica e alle sue applicazioni. Un laureato in queste materie non può non conoscere l’equazione E=mc2 e la media di Gibbs; inoltre deve avere i concetti e i metodi fondamentali della meccanica quantistica che ha cambiato la concezione del mondo ed è alla base della rivoluzione tecnologica in corso. Eppure quelle idee rimangono distanti dal comune modo di pensare e richiedono molto studio e un insegnamento ben mirato. La trattazione in questo libro, è meno formale rispetto ai tradizionali corsi di Istituzioni di Fisica Teorica. Lo scopo è comunque quello di raggiungere una reale comprensione dei concetti fisi...

    Cervical smear material contains endo and exocervical cells, mucus and inflammative, immune cells in cases of pathology. Just not destroyed keratinocytes lay on the glass for microscopy. Liquid cytology supernatant apart other diagnostics could be used for photodiagnostic. The spectroscopic parameters suitable for Normal and HSIL cytology groups supernatant differentiation are demonstrated. The dried liquid PAP supernatant fractions—sediment and liquid were investigated. Excitation and emission matrices (EEM), supernatant fluorescence decay measured under 280 nm diode short pulse excitation and fluorescence spectroscopy by excitation with 355 nm laser light were analyzed. The differences between Normal and HSIL groups were statistically proven in the certain spectral regions. Fluorescence decay peculiarities show spectral regions consisting of few fluorophores. Obtained results on fluorescence differences in Normal and HSIL groups' supernatant shows the potency of photodiagnosis application in cervical screening.

  7. A heterodimer of human 3'-phospho-adenosine-5'-phosphosulphate (PAPS) synthases is a new sulphate activating complex

    2010-01-01

    3'-Phospho-adenosine-5'-phosphosulphate (PAPS) synthases are fundamental to mammalian sulphate metabolism. These enzymes have recently been linked to a rising number of human diseases. Despite many studies, it is not yet understood how the mammalian PAPS synthases 1 and 2 interact with each other. We provide first evidence for heterodimerisation of these two enzymes by pull-down assays and Foerster resonance energy transfer (FRET) measurements. Kinetics of dimer dissociation/association indicates that these heterodimers form as soon as PAPSS1 and -S2 encounter each other in solution. Affinity of the homo- and heterodimers were found to be in the low nanomolar range using anisotropy measurements employing proteins labelled with the fluorescent dye IAEDANS that - in spite of its low quantum yield - is well suited for anisotropy due to its large Stokes shift. Within its kinase domain, the PAPS synthase heterodimer displays similar substrate inhibition by adenosine-5'-phosphosulphate (APS) as the homodimers. Due to divergent catalytic efficacies of PAPSS1 and -S2, the heterodimer might be a way of regulating PAPS synthase function within mammalian cells.

    Capostipite dei "cacciatori di particelle" fu J.J. Thomson, il quale nel 1897 scoprì la prima particella subatomica, l'elettrone. Poco dopo, negli anni tra il 1910 e il 1932, veniva rivelata la natura del nucleo atomico, grazie al lavoro di Rutherford. Partendo da queste prime storiche conquiste della fisica, gli autori introducono gradualmente il lettore nel micromondo delle particelle: dall'elettroscopio a foglie d'oro al dualismo onda-particella, all'enigma di una asimmetria destra-sinistra in natura, all'invenzione dei grandi acceleratori. Poi tra la fine degli anni cinquanta e i primi anni sessanta, l'esplosione di nuove specie particellari sembra vanificare ogni speranza di spiegazione. Lo schema di classificazione introdotto nel 1964 da Ne'eman (e, indipendentemente, da Gell-Mann), pone fine a tale confusione, consentendo una sistemazione coerente: quella che porta al concetto di quark e alle ultime conquiste, teoriche e sperimentali.

    137 Cs one of the major beta gamma emitting fission products present in high level liquid waste (HLLW), which is generated during the reprocessing of spent nuclear fuel. Its separation will restrict the personal radiation exposure during the vitrification and prevents thermal deformation of conditioned waste matrix during storage. Separation will also reduce the volume of vitrified mass to be stored in repository. In addition 137 Cs has enormous applications as radiation sources in food preservation, sterilization of medical products, brachytherapy, blood irradiation, hygienization of sewage sludge etc. The use of 137 Cs (T 1/2 = 30 years) in place of 60 Co (T 1/2 = 5.2 years) will also reduce the shielding requirement, frequency of source replenishment and ease the handling/transportation of radioactive source. Present paper summarises experimental results pertaining to performance evaluation of indigenously synthesised 1, 3 di octyl oxy Calix(4) arene crown 6 (CC6) as extractant for recovery of caesium from HLLW

    In this work the stabilization of hazardous solid wastes containing heavy metals has been studied by means of novel matrices able to generate calcium trisulphoaluminate and silicate hydrates. The process is based on the hydration of two different mixtures containing blast furnace slag, coal ashes, chemical gypsum and Portland cement. The stabilization capacity of the two mixtures has been checked with regard to both a residue from an incinerator of municipal solid wastes and model systems obtained by adding 5 and 10% of soluble nitrates of Cd, Cr, Cu, Ni, Pb and Zn. The stabilized products have been validated from the point of view of mechanical properties by determining the unconfined compressive strength, and from the environmental point of view by means of static and dynamic leaching tests. Both matrices have proved to have great potentiality for the stabilization of hazardous solid wastes, the one based on blast furnace slag being better. Finally, evidence is given that different leaching tests are necessary to fully understand the immobilization mechanism responsible for stabilization.

    To determine if natural human papillomavirus (HPV) infection would induce an anamnestic response to quadrivalent (qHPV) vaccine in women with Systemic Lupus Erythematosus (SLE). Thirty four women (19-50 years) with mild to moderate and minimally active or inactive SLE received standard qHPV vaccine. Neutralizing antibody titers to HPV 6, 11, 16 and18 were evaluated pre- and post- vaccine using HPV competitive Luminex Immunoassay. For each HPV type, logistic regressions were performed to explore the relationship between a positive titer at baseline with their final geometric mean titer and with the rise in titer. Fisher's Exact Test was used to assess the association of at least one positive HPV antibody test at baseline and history of abnormal pap. History of abnormal pap smear/cervical neoplasia occurred in 52.9%. Baseline anti HPV antibody titers: 21% = negative for all 4 HPV types, 79% = positive for ≥1 of the HPV types. Statistical analysis showed: those with a history of abnormal pap smear/cervical neoplasia were likely to have a positive anti-HPV antibody result pre-vaccine to ≥ 1 of the 4 types, p = 0.035 Fisher's Exact Test. In general, HPV exposed women showed higher post vaccine GMTs than HPV unexposed women with higher point estimates. However, when examining the rise in titers using logistic regression, there was no evidence of an anamnestic response. Prior HPV infection and cervical neoplasia in SLE are linked with no anamnestic response to HPV vaccine. This supports not checking HPV-antibodies pre-vaccine. Women with SLE should be vaccinated for HPV.

    Verification of uncertain PAP-smear results in a group of women covered by the cervical screening program in the Podlaski province. The main aim of the study was to identify CIN (Cervical Intraepithelial Neoplasia) lesions present, with varying degrees of severity in women with cytological diagnosis of ASCUS (atypical squamous cells of undetermined significance), LSIL (low grade squamous intraepithelial lesion), and ASC-H (atypical squamous cells - cannot exclude high grade squamous intraepithelial lesion). The study evaluated 101 cervical smears taken from the vaginal part of the cervix in a group of screened women in the Podlaski province. Cytological evaluation was performed according the Bethesda System. We analyzed abnormal smears selected from a total of 7296 cytological examinations performed during 2012 at the University Center for Pathomorphological and Genetic - Molecular Diagnosis, Medical University in Białystok. The cytological results which were of interest to us included 19 cases with ASCUS, 59 with LSIL, and 23 with ASC-H, as well as with morphological features of the presence of Human Papilloma Virus (HPV). Staining was performed using CINtecPLUS test according to the manufacturer's instructions. CINtecPLUS is a immunocytochemical test based on specially designed monoclonal antibodies (E6H4TM) that let us identify protein p16ink4a within the cervical smear Additionally the diagnostic kit was provided with antibodies for diagnosing the presence of Ki-67 protein, a known marker of cell proliferation. The result was considered positive when staining of the nucleus and the cytoplasm appeared in red and brown, respectively. All abnormal results were eventually verified by histological examination of the tissue taken from cervical lesions by diagnostic-therapeutic procedure following colposcopic evaluation of cervical lesion topography In the group of cytological smears with ASCUS, the diagnosis was positive in 5 cases (26.3%), negative in 14 (73

    Full Text Available

    La guida di un autoveicolo, specie in condizioni di intenso traffico o di cattive condizioni meteoclimatiche, è considerata uno dei principali fattori stressanti della vita odierna. Durante la guida si possono infatti osservare significative risposte simpatoadrenergiche e cardiovascolari con la comparsa anche di episodi coronarici. Tali risposte presentano un’ampia variabilità interindividuale in quanto sono influenzate da vari fattori (stile di vita, personalità etc..

    In questa rassegna, vengono presentati i principali risultati degli studi da noi condotti sulle risposte psicofisiologiche indotte dalla guida di diversi tipi di autoveicoli. In conducenti di autobus urbani è stato registrato un sensibile aumento del tasso urinario di adrenalina durante il turno lavorativo rispetto alla stessa fascia oraria di un giorno di riposo. Tale risposta adrenergica era esaltata dall’abitudine tabagica e dall’assunzione di caffè e bevande alcoliche. In soggetti che alla guida di camion coprono lunghe distanze, i più elevati tassi urinari di catecolamine e i più alti livelli di frequenza cardiaca sono stati registrati quando la guida era particolarmente stressante per la presenza di nebbia o di intenso traffico. In soggetti che partecipano, a livello amatoriale, a manifestazioni agonistiche di velocità su pista, abbiamo osservato che durante la gara, rispetto al periodo pre-gara, l’escrezione urinaria di catecolamine aumenta in misura molto rilevante. Analogamente a quanto osservato in autisti di camion, l’attivazione del sistema adrenergico è risultata direttamente associata ai livelli di ansietà. Dall’elettrocardiogramma dinamico è emerso che durante la gara la frequenza cardiaca raggiunge un valore medio di 163.5±7.4 battiti/min. (range: 146,180 battiti/min..

    Un significativo peggioramento della percezione visiva stereoscopica, con potenziale ricaduta negativa sulla performance dei guidatori, è stato osservato in

Nell’articolo non si intende dare una descrizione lessicale completa dei testi odeporici esaminati, ma più limitatamente si presenta una serie cospicua di retrodatazioni e datazioni di parole raccolte in quei testi e quindi ricercate, così allargando lo spettro testuale oltre i limiti della letteratura periegetica, attraverso Google libri. Ma nonostante questo parziale spostamento di sguardo, le schede seguenti continuano a documentare la ricchezza del lessico dell’odeporica: termini scientifici, storici, stranierismi e regionalismi ben testimoniano la varia curiosità dei viaggiatori.  Backdating through travelsSeventeenth and eighteenth century travel literature features, among many points of interest, ideas for researching the history of the language, especially lexical aspects. The article does not intend to give a complete lexical description of the odeporic texts examined, but is limited to a substantial number of backdatings and datings of words collected in those texts, thusgoing beyond the limits of textual periegetic literature, through Google books. Despite this partial shift of attention, we continue to document the richness of odeporic vocabulary: scientifically, historically, through foreign terms and regionalisms, bearing witness to the varied curiosity of travelers.

    The combustion of a dried sewage sludge in laboratory scale fluidized bed has been studied in Naples by the Istituto di ricerche sulla combustione (Irc) in the framework of a National project named Thermal Process with Energy Recovery to be used in laboratory and pre-pilot scale apparatus. The attention has been focused on emissions of unreacted carbon as elutriated fines, on the emissions of pollutant gases and on the assessment of the inventory of fly- and bottom ashes. The combustion behaviour of sewage sludge has been compared with those of a market available Tyre Derived Fuel (TDF) and a biomass from Mediterranean area (Robinia Pseudoacacia) and with that of a South African bituminous coal. Stationary combustion tests were carried out at 850{sup 0} C by feeding particles in the size range 0-1 mm into a bed of silica sand without any sorbent addition. The fluidized bed combustor has been operated, at a superficial gas velocity of 0.4 m/s and different excesses of air ranging between 14 and 98%. Relatively high combustion efficiency, larger than 98.9% has been obtained in experiments carried out with sewage sludge and excess of air larger than 20%.

    The appropriate management of women with minor cytologic lesions in their cervix is unclear. We performed a meta-analysis to assess the accuracy of human papillomavirus (HPV) DNA testing as an alternative to repeat cytology in women who had equivocal results on a previous Pap smear. Data were extracted from articles published between 1992 and 2002 that contained results of virologic and cytologic testing followed by colposcopically directed biopsy in women with an index smear showing atypical cells of undetermined significance (ASCUS). Fifteen studies were identified in which HPV triage and the histologic outcome (presence or absence of a cervical intraepithelial neoplasia of grade II or worse [CIN2+]) was documented. Nine, seven, and two studies also documented the accuracy of repeat cytology when the cutoff for abnormal cytology was set at a threshold of ASCUS or worse, low-grade squamous intraepithelial lesion (LSIL) or worse, or high-grade squamous intraepithelial lesion (HSIL) or worse, respectively. Random-effects models were used for pooling of accuracy parameters in case of interstudy heterogeneity. Differences in accuracy were assessed by pooling the ratio of the sensitivity (or specificity) of HPV testing to that of repeat cytology. The sensitivity and specificity were 84.4% (95% confidence interval [CI] = 77.6% to 91.1%) and 72.9% (95% CI = 62.5% to 83.3%), respectively, for HPV testing overall and 94.8% (95% CI = 92.7% to 96.9%) and 67.3% (95% CI = 58.2% to 76.4%), respectively, for HPV testing in the eight studies that used the Hybrid Capture II assay. Sensitivity and specificity of repeat cytology at a threshold for abnormal cytology of ASCUS or worse was 81.8% (95% CI = 73.5% to 84.3%) and 57.6% (95% CI = 49.5% to 65.7%), respectively. Repeat cytology that used higher cytologic thresholds yielded substantially lower sensitivity but higher specificity than triage with the Hybrid Capture II assay.

    Full Text Available Examples of Cultural Anti-Semitism in Umberto Eco’s Novel Il cimitero di PragaThe article draws upon Umberto Eco’s recent novel, Il cimitero di Praga, in the consideration of the relationship between narrative fiction and the collective imagination in regards to the genesis and dispersion of The Protocols of the Elders of Zion in the second half of the nineteenth century. A dangerous and mysterious text, The Protocols evoked general clamor and persecutory backlash, as it appeared to document the existence of a Judeo-Masonic conspiracy.In the work, the author also reconstructs sources of the fictional text and traces the historical, political and editorial events surrounding it, plunging into them with a gritty and irreverent realism in a chronicle of the obsession that flowed into the madness of the Shoah.Treating the subject, which is found elsewhere in the scholar’s oeuvre, requires mention of the repertoire of prejudicial accusations against the Jews throughout history, which creates, toward the end of the book, a heated and contentious debate regarding whether such delicate and reckless statements should even be made public at all. This article questions the authorial strategy in Il cimitero di Praga, and considers the novel’s literary agenda, which can be almost interpreted as a call for vigilance against manifestations of anti-Semitism still present in today’s cultural imagination.

    Full Text Available E’ stato eseguito uno studio comparativo tra 22 ceppi di Salmonella Hadar isolati da soggetti coinvolti in un focolaio di tossinfezione alimentare in Abruzzo nel 2000 e 21 ceppi dello stesso sierotipo isolati da carni avicole e da feci umane in Abruzzo e Molise nel periodo 2000 e 2001. L’indagine aveva come obiettivo di fornire una interpretazione epidemiologica del focolaio di tossinfezione alimentare determinando il grado di similarità tra i ceppi di Salmonella Hadar isolati dai soggetti coinvolti nel focolaio, quelli isolati da carne avicola, identificata ma non confermata come possibile fonte di infezione, e da altri campioni umani pervenuti in laboratorio. A tal fine sono state impiegate tecniche di caratterizzazione genotipica come pulsed-field gel electrophoresis (PFGE e random amplified polymorphic DNA (RAPD e sono stati determinati i pattern di resistenza agli antimicrobici. Dall’analisi in PFGE dei profili di restrizione ottenuti con XbaI e BlnI sono stati identificati 12 pulsotipi suddivisi in 3 gruppi. La RAPD non ha fornito indicazioni non riuscendo a discriminare i ceppi isolati dai soggetti con gastroenterite appartenenti al focolaio tossinfettivo. Il test di resistenza agli antimicrobici ha evidenziato pattern di resistenza multipla ma non sono stati identificati ceppi resistenti al Ciprofloxacin o altri Chinoloni testati. I ceppi aviari sono risultati resistenti all’acido nalidixico mentre solo il 31,8% di quelli umani ha presentato tale profilo. Da un’analisi combinata dei pattern di resistenza e dei pulsotipi sono stati identificati 4 profili di cui quello associato al focolaio è risultato non correlato agli altri presenti nello stesso periodo. E’ stata confermata la necessità di applicare un set di metodi di analisi differenti per garantire una migliore caratterizzazione e una maggiore capacità discriminante nell’identificazione delle possibili origini della contaminazione e stabilire correlazioni fra gli

    Full Text Available Il presente articolo riguarda la modellazione del comportamento meccanico di elementi in muratura intesi come sistemi eterogenei composti da malta, blocchi ed interfacce di connessione. La strategiacomputazionale che viene adottata consiste nel modellare separatamente i blocchi, i letti di malta ed le interfacce responsabili di fenomeni di decoesione malta-blocco; a tale scopo, si propone uno speciale modello di interfaccia che combina il danneggiamento con l’attrito. Si sviluppa una procedura numerica, basata sull’algoritmo backward di Eulero, per risolvere il problema evolutivo; per il passo temporale si utilizza invece la tecnica predictor-corrector a controllo di spostamenti. Si effettuano alcune applicazioni numeriche con lo scopodi verificare la capacità del modello e dell’algoritmo proposto nel riprodurre la risposta non lineare della muratura dovuta a fenomeni di degrado localizzati. Infine, si conduce lo studio della modellazione di un arco murario, confrontando i risultati numerici con quelli sperimentali; si dimostra la abilità del modello proposto nel simulare il comportamento globale della struttura ad arco in termini di carico ultimo e di meccanismo di collasso.

  10. Region-based multifocus image fusion for the precise acquisition of Pap smear images.

    2018-05-01

    A multifocus image fusion method to obtain a single focused image from a sequence of microscopic high-magnification Papanicolau source (Pap smear) images is presented. These images, captured each in a different position of the microscope lens, frequently show partially focused cells or parts of cells, which makes them unpractical for the direct application of image analysis techniques. The proposed method obtains a focused image with a high preservation of original pixels information while achieving a negligible visibility of the fusion artifacts. The method starts by identifying the best-focused image of the sequence; then, it performs a mean-shift segmentation over this image; the focus level of the segmented regions is evaluated in all the images of the sequence, and best-focused regions are merged in a single combined image; finally, this image is processed with an adaptive artifact removal process. The combination of a region-oriented approach, instead of block-based approaches, and a minimum modification of the value of focused pixels in the original images achieve a highly contrasted image with no visible artifacts, which makes this method especially convenient for the medical imaging domain. The proposed method is compared with several state-of-the-art alternatives over a representative dataset. The experimental results show that our proposal obtains the best and more stable quality indicators. (2018) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).

    Pulmonary hypertension (PH) is associated with a poor outcome in chronic obstructive pulmonary disease (COPD) and is diagnosed invasively. We aimed to assess the diagnostic accuracy and prognostic value of non-invasive cardiovascular magnetic resonance (CMR) models. Patients with COPD and suspected PH, who underwent CMR and right heart catheter (RHC) were identified. Three candidate models were assessed: 1, CMR-RV model, based on right ventricular (RV) mass and interventricular septal angle; 2, CMR PA/RV includes RV mass, septal angle and pulmonary artery (PA) measurements; 3, the Alpha index, based on RV ejection fraction and PA size. Of 102 COPD patients, 87 had PH. The CMR-PA/RV model had the strongest diagnostic accuracy (sensitivity 92%, specificity 80%, positive predictive value 96% and negative predictive value 63%, AUC 0.93, p<0.0001). Splitting RHC-mPAP, CMR-RV and CMR-PA/RV models by 35mmHg gave a significant difference in survival, with log-rank chi-squared 5.03, 5.47 and 7.10. RV mass and PA relative area change were the independent predictors of mortality at multivariate Cox regression (p=0.002 and 0.030). CMR provides diagnostic and prognostic information in PH-COPD. The CMR-PA/RV model is useful for diagnosis, the RV mass index and PA relative area change are useful to assess prognosis. (orig.)

    Given the importance of papanicolaou (Pap) test in the early detection and timely treatment of cervical cancer, present study was designed to determine predictors of a sample of Iranian women's intention to first Pap test practice based on the protection motivation theory (PMT) variables. In this cross-sectional study, a total of 240 women referral to the 30 primary health care clinics were selected. They completed a developed scale based on PMT variables including intention, perceived vulnerability and severity, fear, response costs, response efficacy and self-efficacy. Path analysis was used to determine the association between predictive factors and intention. The results showed that PMT had goodness of fit with a χ2/df = 2.37, df = 28, P= 0.001 and RMSEA = 0.076. PMT explained 42% of the variance in women's intention to get first Pap smear test. Self-efficacy (b = 0.55, Ptheory-based educational interventions associated with Pap testing among women.

    Full Text Available Semen harbors amyloid fibrils formed by proteolytic fragments of prostatic acid phosphatase (PAP248-286 and PAP85-120 and semenogelins (SEM1 and SEM2 that potently enhance HIV infectivity. Amyloid but not soluble forms of these peptides enhance HIV infection. Thus, agents that remodel these amyloid fibrils could prevent HIV transmission. Here, we confirm that the green tea polyphenol, epigallocatechin-3-gallate (EGCG, slowly remodels fibrils formed by PAP248-286 termed SEVI (semen derived enhancer of viral infection and also exerts a direct anti-viral effect. We elucidate for the first time that EGCG remodels PAP85-120, SEM1(45-107, and SEM2(49-107 fibrils more rapidly than SEVI fibrils. We establish EGCG as the first small molecule that can remodel all four classes of seminal amyloid. The combined anti-amyloid and anti-viral properties of EGCG could have utility in preventing HIV transmission.

    HPV is one of the most common sexually transmitted infections. However, little is known about its prevalence in the female population in Rasht, Northern of Iran. The aim of this study was to find the incidences of HPV viruses in high-risk women in Rasht by wet Pap smear from 2010 to 2015. This cross-sectional study investigated HPV prevalence and its genotype distribution among 103 apparently healthy and non- healthy women with abnormal cells in pap exam. DNA samples were extracted by boiling and phenol - chloroform methods, then used as template for amplifying of specific fragment of HPV genome by PCR using GP5+ / GP6+ primers. PCR products were electrophoresed in 1.5% agarose gel (Roche, Germany) containing Sybrsafe. DNA ladder (Roche Co, Germany) was used to detect the molecular weights of observed bands under UV lamp. Overall, 4/98 women (4.08%) with normal cells and 1/5 women (20%) with abnormal cells were positive for at least one of the high risk HPV types in wet Pap smear. The most HPV infection was found in 26 to 39-year-old individuals. We evidenced a moderate prevalence of HPV infection but needs to be given more attention because in apparently healthy women also, HPV infection was observed. Health officials should conduct the study and wider screening of this infection occurring in this province. Screening for this infection must be recommended in this region.

    Full Text Available Abstract Background The incidence of invasive cervical cancer in HIV-positive women is higher than in the general population. There is evidence that HIV-positive women do not participate sufficiently in cervical cancer screening in Italy, where cervical cancer is more than 10-fold higher in women with AIDS than in the general population. The aim of the present study was to evaluate the history of Pap-smear in HIV-positive women in Italy in recent years. We also examined the sociodemographic, clinical, and organizational factors associated with adherence to cervical cancer screening. Methods A cross-sectional study was conducted between July 2006 and June 2007 in Emilia-Romagna region (Northern Italy. All HIV-positive women who received a follow-up visit in one of the 10 regional infectivology units were invited to participate. History of Pap-smear, including abnormal smears and subsequent treatment, was investigated through a self-administered anonymous questionnaire. The association between lack of Pap-smear in the year preceding the interview and selected characteristics was assessed by means of odds ratios (OR and 95% confidence intervals adjusted for study centre and age. Results A total of 1,002 HIV-positive women were interviewed. Nine percent reported no history of Pap-smear, and 39% had no Pap-smear in the year prior to the date of questionnaire (last year. The lack of Pap-smear in the last year was significantly associated with age Three hundred five (34% women reported a previous abnormal Pap-smear, and of the 178 (58% referred for treatment, 97% complied. Conclusions In recent years the self-reported history of Pap-smear in HIV-positive women, in some public clinics in Italy, is higher than previously reported, but further efforts are required to make sure cervical cancer screening is accessible to all HIV-positive women.

    Scientific data about the effects of positive airway pressure (PAP) treatment on blood pressure (BP) control are continuously increasing; however, they are controversial. We aimed to determine the long-term effects of compliance with PAP therapy on BP in both hypertensive and normotensive patients with obstructive sleep apnea-hypopnea syndrome (OSAHS). One thousand one hundred sixty eight consecutive patients with newly diagnosed OSAHS, who had been recommended PAP therapy, were followed up for a minimum of 2 years. Patients with previous cardiovascular disease were excluded. BP was measured at baseline and after 2 years of PAP treatment. In addition, the correlation between the changes in BP with different levels of PAP compliance was assessed. At the end of the follow-up period, in the hypertensive group of patients (n=586), a significant decrease was shown in systolic (-11.2 mm Hg, P<0.001) and diastolic BP (-4.2 mm Hg, P<0.001). Furthermore, in the patients without hypertension (n=528), a significant decrease was noted both in systolic and diastolic BP (-3.6, P<0.001 and -2.4, P<0.001, respectively). A correlation between the magnitude of change in systolic and diastolic BP and hours of use of PAP (r=0.14, P=0.002 and r=0.1, P=0.025, respectively) was observed in all patients. Long-term use of PAP treatment, as well as increased hours of PAP in patients with OSAHS use showed significant reductions in BP not only in patients with hypertension, but also in normotensive patients. Therefore a significant potential reduction in cardiovascular mortality and morbidity should be expected in these patients.

    Ludwig Boltzmann (1844-1906) è il fisico e matematico austriaco che negli ultimi decenni dell'Ottocento e ancora ai primi del Novecento lottò contro l'opinione dominante tra gli scienziati dell'epoca per affermare la teoria atomica della materia. È noto come con Albert Einstein e fino a oggi la fisica si sia sviluppata e abbia celebrato i propri trionfi lungo le linee anticipate da Boltzmann. La controversia con Mach non riguardava soltanto l'esistenza degli atomi, ma l'intero modo di fare fisica che Boltzmann non riteneva di dover limitare allo studio di quantità misurabili, introducendo invece spiegazioni più elaborate basate su ipotesi più ampie.

    Primary human papillomavirus (HPV) testing (without concurrent Pap tests) every 3 years is under consideration in the United States as an alternative to the two recommended cervical cancer screening strategies: primary Pap testing every 3 years, or concurrent Pap and HPV testing ("cotesting") every 5 years. Using logistic regression and Weibull survival models, we estimated and compared risks of cancer and cervical intraepithelial neoplasia grade 3 or worse (CIN3+) for the three strategies among 1011092 women aged 30 to 64 years testing HPV-negative and/or Pap-negative in routine screening at Kaiser Permanente Northern California since 2003. All statistical tests were two sided. Three-year risks following an HPV-negative result were lower than 3-year risks following a Pap-negative result (CIN3+ = 0.069% vs 0.19%, P < .0001; Cancer = 0.011% vs 0.020%, P < .0001) and 5-year risks following an HPV-negative/Pap-negative cotest (CIN3+ = 0.069% vs 0.11%, P < .0001; Cancer = 0.011% vs 0.014%, P = .21). These findings suggest that primary HPV testing merits consideration as another alternative for cervical screening. © Published by Oxford University Press 2014.

  6. A Peptide Derived from the HIV-1 gp120 Coreceptor-Binding Region Promotes Formation of PAP248-286 Amyloid Fibrils to Enhance HIV-1 Infection.

    Directory of Open Access Journals (Sweden)

    Jinquan Chen

    Full Text Available Semen is a major vehicle for HIV transmission. Prostatic acid phosphatase (PAP fragments, such as PAP248-286, in human semen can form amyloid fibrils to enhance HIV infection. Other endogenous or exogenous factors present during sexual intercourse have also been reported to promote the formation of seminal amyloid fibrils.Here, we demonstrated that a synthetic 15-residue peptide derived from the HIV-1 gp120 coreceptor-binding region, designated enhancing peptide 2 (EP2, can rapidly self-assemble into nanofibers. These EP2-derivated nanofibers promptly accelerated the formation of semen amyloid fibrils by PAP248-286, as shown by Thioflavin T (ThT and Congo red assays. The amyloid fibrils presented similar morphology, assessed via transmission electron microscopy (TEM, in the presence or absence of EP2. Circular dichroism (CD spectroscopy revealed that EP2 accelerates PAP248-286 amyloid fibril formation by promoting the structural transition of PAP248-286 from a random coil into a cross-β-sheet. Newly formed semen amyloid fibrils effectively enhanced HIV-1 infection in TZM-bl cells and U87 cells by promoting the binding of HIV-1 virions to target cells.Nanofibers composed of EP2 promote the formation of PAP248-286 amyloid fibrils and enhance HIV-1 infection.

    Although classified as Gram-positive bacteria, Corynebacterineae possess an asymmetric outer membrane that imparts structural and thereby physiological similarity to more distantly related Gram-negative bacteria. Like lipopolysaccharide in Gram-negative bacteria, lipids in the outer membrane of Corynebacterineae have been associated with the virulence of pathogenic species such as Mycobacterium tuberculosis (Mtb). For example, Mtb strains that lack long, branched-chain alkyl esters known as dimycocerosates (DIMs) are significantly attenuated in model infections. The resultant interest in the biosynthetic pathway of these unusual virulence factors has led to the elucidation of many of the steps leading to the final esterification of the alkyl beta-diol, phthiocerol, with branched-chain fatty acids know as mycocerosates. PapA5 is an acyltransferase implicated in these final reactions. We here show that PapA5 is indeed the terminal enzyme in DIM biosynthesis by demonstrating its dual esterification activity and chain-length preference using synthetic alkyl beta-diol substrate analogues. Applying these analogues to a series of PapA5 mutants, we also revise a model for the substrate binding within PapA5. Finally, we demonstrate that the Mtb Ser/Thr kinase PknB modifies PapA5 on three Thr residues, including two (T196, T198) located on an unresolved loop. These results clarify the DIM biosynthetic pathway and suggest possible mechanisms by which DIM biosynthesis may be regulated by the post-translational modification of PapA5.

    Full Text Available Il Museo Civico di Zoologia di Roma è sorto nel 1932 all?interno del Giardino Zoologico dell?allora Governatorato di Roma, di cui ha condiviso la direzione tecnica ed amministrativa sino al 1998. Il nucleo centrale delle collezioni è costituito dal materiale di proprietà universitaria, di quello che fu il Museo di Zoologia della Regia Università, a sua volta diretto discendente delle collezioni del Museo di Zoologia ed Anatomia Comparata del Pontificio Archiginnasio Romano. La quasi totalità degli esemplari tassidermizzati risale al periodo in cui l?Istituto di Zoologia fu diretto da Antonio Carruccio (1883-1914. Dal 1932, la collezione teriologica si è andata arricchendo, in particolare di materiale osteologico, soprattutto con acquisizioni provenienti dal Giardino Zoologico e da rare spedizioni scientifiche, come quella organizzata dal CNR nell?Alto Rio Negro del 1962-3, guidata da Ettore Biocca. Anche a causa del fatto che per molti anni il Museo è stato privo di curatori, mancano importanti collezioni teriologiche da studio, fatta eccezione per quella cetologica. In molti casi, singoli esemplari potenzialmente di grande valore scientifico, mancano di dati esatti sulla località di cattura. Nell?ambito di un programma di ricatalogazione della collezione recentemente intrapreso, particolare attenzione è stata posta all?acquisizione di tutti i dati legati alla storia dei singoli esemplari, rintracciabili attraverso i resoconti di viaggio dei singoli esploratori. Nel periodo universitario, infatti, il Museo della nuova capitale d?Italia fu oggetto di grande attenzione da parte di privati ed enti, a partire dai Savoia, che donarono le loro collezioni o il materiale raccolto durante le spedizioni effettuate. Il lavoro di revisione in corso sta mettendo in luce una serie di esemplari meritevoli di ulteriori, dettagliate ricerche. È probabile che molto del materiale del Museo, pervenuto a Roma attraverso donazioni della famiglia reale

    Obiettivi: é noto che effettuare diagnosi di Legionellosi risulta difficile a causa della sovrapposizione della sintomatologia con altre forme di polmonite. Questo spiega, in parte, perché i casi di Legionellosi siano sottostimati. I metodi diagnostici disponibili, sebbene richiedano tempi relativamente lunghi, sono necessari per l’esatta stima di prevalenza della Legionellosi e per gli eventuali interventi preventivi.

    Metodi: nell’Azienda Ospedaliera “G. Panico” di Tricase, seguendo i criteri delle Linee Guida della Legionellosi (G.U. 5 maggio 2000 n. 103 durante la degenza dei pazienti che presentavano segni clinici ed obiettivi di polmonite sono state eseguite indagini radiologiche (Rx Torace, TAC, esami di laboratorio (espettorato, sangue, urina ed avviata terapia antibiotica (macrolidi e cefalosporine di III generazione. L’antigene urinario e le IgG anti-Legionella (metodo IFA, sono stati determinati in collaborazione con il Laboratorio di riferimento Regionale.

    Risultati: nel periodo ottobre 2001 gennaio 2003 sono stati notificati nel nostro ospedale 11 casi di Legionellosi accertati da indagini clinico-strumentali e di laboratorio: tutti i casi avevano titoli anticorpali abbastanza elevati, confermati poi da un secondo controllo a distanza di tempo. Solo due hanno presentato una positività per l’antigene urinario. All’atto della dimissione, per il 63.6% dei casi è stato documentato un miglioramento delle condizioni clinico-laboratoristico-strumentali, nel 18.2% si è avuta una effettiva guarigione. La letalità è stata pari al 18.2%. In tutti casi si è provveduto alla sorveglianza ambientale.

    Considerazioni: i nostri dati evidenziano che i casi di Legionellosi registrati sono stati tutti di tipo comunitario. Una corretta applicazione delle Linee Guida nel sistema di notifica permette l’avvio dell’attività di prevenzione oltre

    Obiettivi: valutare la prevalenza sieropositività per HIV, HBV e HCV nei tossicodipendenti afferenti al Ser.T di Formia (LT.

    Materiali e metodi: sono state consultate le cartelle cliniche degli afferenti al Ser.T. nel 2002, estraendo dati relativi ai parametri socio-demografici ed alle sieropositività. L’analisi statistica ha previsto l’impiego del test del χ2 e della regressione logistica multipla.

    Risultati: sono stati presi in considerazione 135 tossicodipendenti, di cui 103 (76.3% maschi e 32 (23.7% femmine. L’età mediana dell’inizio della tossicodipendenza e della presa in carico presso il servizio erano, rispettivamente, di 18 e di 23 anni. Il 94.1% dei tossicodipendenti risulta dipendente primariamente da eroina, il 5.2% da cocaina e lo 0.7% da alcol. Relativamente alle positività per i virus considerati, 7 soggetti (5.2% sono risultati positivi all’HIV, 23 (17% sieropositivi per HBV e 50 (37% sieropositivi per HCV. L’analisi multivariata mostra che sono associate alla sieropositività per HCV la sieropositività per HBV (OR = 3.87 e l’età della presa in carico presso il servizio superiore a 25 anni (OR = 1.88; alla sieropositività per HBV l’occupazione saltuaria (OR = 4.58, la HCV positività (OR = 4.41 e la HIV positività (OR = 5.39; alla sieropositività per HIV l’età della presa in carico presso il servizio superiore a 25 anni (OR = 4.94.

    Discussione: l’indagine ha messo in evidenza prevalenze di sieropositività per HCV, HBV e HIV decisamente inferiori a quelle registrate in altre realtà italiane ed internazionali. Una possibile spiegazione potrebbe essere ricercata nei bassi livelli di sieropositività per questi virus nella popolazione generale del Basso Lazio, o nella scarsa abitudine di scambiarsi le siringhe fra tossicodipendenti di questa area geografica.

Methods: Susceptibility tests were carried out using an agar diffusion method, the E-test (AB Biodisk, Solna, Sweden. Results: Strains were selected because of their resistance to individual antimicrobial agents, tested with automated system (Phoenix, BD, which ranged from 41.6% for ceftazidime to 83.3% for ciprofloxacin for Burkholderia cepacia and from 25% for ceftazidime to 100% for trimethoprim-sulfamethoxazole for Pseudomonas aeruginosa. By using E-test,we were able to demonstrate synergy against 2 strains of Pseudomonas aeruginosa (25% with ceftazidime- piperacillin/tazobactam. No synergy was detected against all strains of Burkholderia cepacia. Conclusions:These results suggest that the E-test offers a simple, labour-efficient and accurate method for MIC determination on agar medium and the susceptibility to antibiotic combinations greatly improves the guide to antibiotic therapy for infections to Gram-negative bacteria in Cystic Fibrosis patients.

  2. Il concetto di Natura nella filosofia di Denis Diderot

    Directory of Open Access Journals (Sweden)

    2014-03-01

    Full Text Available L’immagine della Natura che emerge dalla lettura delle opere di Diderot, è quella di una sorta di organismo in cui tutto risulta legato da una rete di forze inquadrate in un ordine omogeneo e dinamico. Le leggi di quest’ordine sono riscontrabili in tutti gli eventi naturali ed ogni fenomeno non è mai frutto del caso, ma ordinato deterministicamente. Allo spinozismo di quest’ordine geometrico si coniuga un atomismo di matrice epicurea, speci camente nella versione lucreziana del De Rerum Natura: gli atomi che costituiscono la materia si combinano da sempre e all’in nito in un continuo divenire di forme normate da leggi intrinseche, e gli individui nascono dal cozzare e dall’ammassarsi di questi atomi. Non esiste uno stadio culmine di questa “evoluzione”, piuttosto esistono in nite varianti, nel tempo e nello spazio, di un unico modello prototipico che, secondo Diderot, evolve in una specie o in un'altra in maniera totalmente a- nalistica, sebbene assolutamente determinis- tica. La regolarità dell’ordine (per no nell’apparente caos di un turbine di pol- vere e il continuo farsi e rifarsi delle forme si connettono al principio di conti- nuità della natura: la natura non fa salti, tutto è connesso come in una ragnatela e la materia continua muta la sua disposizione in grumi di atomi che, secondo il principio dell’epigenesi, giungono a formare gli individui. Le opere in cui Diderot elabora in maniera più organica e precisa la sua concezione della natura sono particolarmente due: L’interpretazione della natura (1753 e Il sogno di d’Alembert (1769. In mezzo a queste stanno gli scritti sui Sa- lons, tra i quali è particolarmente saliente, per il discorso sulla natura, quello del 1767, in cui, con la Promenade Vernet, molti di questi temi vengono a rontati o ripresi nel pittoricismo della narrazione, attraverso limpide metafore. Natura e arte, in Diderot, sono strettamente connesse. La seconda imita la prima, ma non tenta

    Mucositis is one of the most relevant gastrointestinal inflammatory conditions in humans, generated by the use of chemotherapy drugs, such as 5-fluoracil (5-FU). 5-FU-induced mucositis affects 80% of patients undergoing oncological treatment causing mucosal gut dysfunctions and great discomfort. As current therapy drugs presents limitations in alleviating mucositis symptoms, alternative strategies are being pursued. Recent studies have shown that the antimicrobial pancreatitis-associated protein (PAP) has a protective role in intestinal inflammatory processes. Indeed, it was demonstrated that a recombinant strain of Lactococcus lactis expressing human PAP (LL-PAP) could prevent and improve murine DNBS-induced colitis, an inflammatory bowel disease (IBD) that causes severe inflammation of the colon. Hence, in this study we sought to evaluate the protective effects of LL-PAP on 5-FU-induced experimental mucositis in BALB/c mice as a novel approach to treat the disease. Our results show that non-recombinant L. lactis NZ9000 have antagonistic activity, in vitro, against the enteroinvasive gastrointestinal pathogen L. monocytogenes and confirmed PAP inhibitory effect against Opportunistic E. faecalis. Moreover, L. lactis was able to prevent histological damage, reduce neutrophil and eosinophil infiltration and secretory Immunoglobulin-A in mice injected with 5-FU. Recombinant lactococci carrying antimicrobial PAP did not improve those markers of inflammation, although its expression was associated with villous architecture preservation and increased secretory granules density inside Paneth cells in response to 5-FU inflammation. We have demonstrated for the first time that L. lactis NZ9000 by itself, is able to prevent 5-FU-induced intestinal inflammation in BALB/c mice. Moreover, PAP delivered by recombinant L. lactis strain showed additional protective effects in mice epithelium, revealing to be a promising strategy to treat intestinal mucositis.

    Oxygen is one of the most important variables measured in oceanography, influenced both by physical and biological factors. During the OSMOSIS project, 7 Seagliders were used in 3 subsequent missions to measure a multidisciplinary suite of parameters at high frequency in the top 1000 m of the water column for one year, from September 2012 to September 2013. The gliders were deployed at the PAP time series station (nominally at 49° N 16.5° W) and surveyed the area following a butterfly-shaped path. Oxygen concentration was measured by Aanderaa optodes and calibrated using ship CTD O2 profiles during 5 deployment and recovery cruises, which were in turn calibrated by Winkler titration of discrete samples. The oxygen-rich mixed layer deepens in fall and winter and gets richer in oxygen when the temperature decreases. The spring bloom did not happen as expected, but instead the presence of a series of small blooms was measured throughout spring and early summer. During the summer the mixed layer become very shallow and oxygen concentrations decreased. A Deep Oxygen Maximum (DOM) developed along with a deep chlorophyll maximum during the summer and was located just below the mixed layer . At this depth, phytoplankton had favourable light and nutrient conditions to grow and produce oxygen, which was not subject to immediate outgassing. The oxygen concentration in the DOM was not constant, but decreased, then increased again until the end of the mission. Intrusions of oxygen rich water are also visible throughout the mission. These are probably due to mesoscale events through the horizontal transport of oxygen and/or nutrients that can enhance productivity, particularly at the edge of the fronts. We calculate net community production (NCP) by analysing the variation in oxygen with time. Two methods have been proposed. The classical oxygen budget method assumes that changes in oxygen are due to the sum of air-sea flux, isopycnal advection, diapycnal mixing and NCP. ERA

    We have made a comprehensive study of pigment distributions and microscopically determined phytoplankton abundances within the Porcupine Abyssal Plain (PAP) location in the North Atlantic to better understand phytoplankton variability, and make some suggestions regarding the composition of the material falling to the sea bed and its impacts on benthic organisms such as Amperima rosea. The area has been the focus of many studies of ocean fluxes and benthic communities over recent years, but little attention has been given to the spatio-temporal variability in the surface waters. Dawn casts over a 12-day period at the PAP mooring site (48.83°N 16.5°W) revealed the presence of only one species, the diatom Actinocyclus exiguus, at bloom concentrations for just 5 days. Smaller populations of other diatoms and the dinoflagellates Gymnodinium and Gyrodinium were also present at this time. Following this 5-day interval, a mixed population of small-sized dinoflagellates, prymnesiophytes, prasinophytes, chrysophytes and cyanobacteria occurred. It is clear from concomitant CTD/bottle surveys that rapid changes in phytoplankton community structure at a fixed time series position do not necessarily reflect a degradation or manifestation of one particular species but rather represent the movement of eddies and other water masses within very short timescales. These cause substantial variability in the species class and size fraction that may explain the variability in carbon export that has been seen at the PAP site. We also make some suggestions on the variable composition of the material falling to the seabed and its impact on benthic organisms such as Amperima rosea.

    The outbreak of bovine spongiform encephalopathy (BSE) in the United Kingdom in 1986, with processed animal proteins (PAPs) as the main vector of the disease, has led to their prohibition in feed. The progressive release of the feed ban required the development of new analytical methods to determine the exact origin of PAPs from meat and bone meal. We set up a promising MS-based method to determine the species and the source (legal or not) present in PAPs: a TCA-acetone protein extraction followed by a cleanup step, an in-solution tryptic digestion of 5 h (with a 1:20 protein/trypsin ratio), and mass spectrometry analyses, first without any a priori, with a Q-TOF, followed by a targeted triple-quadrupole analysis. Using this procedure, we were able to overcome some of the major limitations of the official methods to analyze PAPs, detecting and identifying prohibited animal products in feedstuffs by the monitoring of peptides specific for cows, pigs, and sheep in PAPs.

    Early detection of oral cancer has been the most effective approach to reduce morbidity and mortality of cancer patients. If a lesion is clinically considered suspicious, an easily practicable, non-invasive, painless, safe, and accurate screening method for detection of the dysplastic changes is necessary. In an attempt to procure this, a study was conducted with the aim of determining the diagnostic accuracy of rapid Papanicolaou stain (PAP) and silver-stained nucleolar organizer regions (AgNOR) in brush biopsies of potentially malignant lesions for early detection of oral cancer. Brush biopsies taken from 25 cases of leukoplakia and lichen planus each were stained with rapid PAP and silver nitrate stains. Histopathological correlation was performed and further compared with rapid PAP and AgNOR for its diagnostic validity. Statistically significant increase in the mean AgNOR count was seen from normal epithelium to lichen planus to that of leukoplakia. When compared with rapid PAP, a linear correlation was seen in AgNOR counts and stages of dysplasia in leukoplakia which was also found to be statistically significant. Diagnostic accuracy for AgNOR in leukoplakia was found to be 84%, lichen planus 73%, whereas RAPID PAP showed 72% accuracy. AgNOR analysis may be useful as a quantitative marker of incipient cellular alterations and hence would be helpful in assessing suspicious lesions and thus can be regarded as a valuable adjunct. © 2016 John Wiley & Sons A/S.

    Cervical cancer is a serious health problem and stated as the second cause of death of woman worldwide. Several studies have noted a higher incidence of cervical cancer with increasing parity. Early detection with Pap smear is proven to reduce mortality of patients. Knowledge, attitude and husband’s support contributed to theled womanto follow Pap smear examination. This study explores the knowledge of cervical cancer, attitude and husband’ s support of Pap smearin multiparous women that have Pap smear examination. This research is a quantitative study with cross sectional approach recruited 50 respondents as multiparous women that have Pap smear examination inAviati Clinic, Padang Bulan, Medan. The data were collected by self-reports using structured objectives by questionnaires. The result of this study showed that 66% respondents have high knowledge of cervical cancer and 76% respondents have ahigh attitude of Pap smear, but they almost have low husband’s support of Pap smear including information support (62%), emotional support (46%) and real support (50%). This study has revealed that multiparous women that had Pap smear examination generally had high knowledge about cervical cancer and positive attitude about Pap smear, even most of them had low husband’s support.

    The characteristic features of Papanicolaou (Pap) tests collected from female-to-male (FTM) transgender patients on androgen therapy have not been well defined in the literature. FTM transgender patients require cervical cancer screening with the same recommended frequency as cis-gender females. Dysplasia remains challenging to differentiate from atrophy. Without pertinent history, the atrophic findings in younger transgender patients can be misinterpreted as high-grade dysplasia. A review of all cervical Pap tests of transgender patients receiving androgen therapy (2010-2017) was performed. Bethesda diagnosis, cytomorphological features, HPV testing and cervical biopsy results were reviewed. Eleven transgender patients receiving androgen therapy were identified with 23 cervical Pap tests, 11 HPV tests and five cervical biopsies performed. A review of the Pap tests demonstrated: 57% negative for intraepithelial lesion; 13% unsatisfactory; 13% atypical squamous cells of undetermined significance; 13% atypical squamous cells - cannot exclude high-grade squamous intraepithelial lesion; and 4% high-grade squamous intraepithelial lesion. The rates of abnormal tests were higher than our age-matched cis-gender atrophic cohort rates of unsatisfactory (0.5%), atypical squamous cells of undetermined significance (7%), atypical squamous cells-cannot exclude high-grade squamous intraepithelial lesion (0%) and high-grade squamous intraepithelial lesion (0.5%). The cytological findings from liquid-based preparations included dispersed and clustered parabasal-type cells, scattered degenerated cells, smooth evenly dispersed chromatin, and occasional mild nuclear enlargement and irregularity. Dysplastic cells had larger nuclei, hyperchromatic clumped chromatin, and more irregular nuclear contours. The evaluation of dysplasia can be challenging on Pap tests from transgender patients on androgen therapy. The cohort evaluated had higher rates of unsatisfactory and abnormal Pap tests

    The cytotoxic activity of cancer chemotherapy is related to the dose and to the amount of drug delivered per time unit. the significance of time in the effectiveness of a treatment program is frequently overlooked. The term of dose intensity (DI) is used to define the drug dose delivered per time unit and is expressed as mg/m 2 per week. A delay in the sequence of treatment cycles decreases the DI in the DI in the same proportion as a reduction of dose. Average relative DI corresponds to the mean DI of combined agents and is expressed as a fraction of a similar combination selected as a standard. Di is useful to compare the dose actually received with the prescribed dose. The relation of DI with tumor response or survival has not been fully demonstrated. A threshold DI level for therapeutic activity is evident. Above this threshold, a linear relationship of DI and effectiveness is not obvious, particularly regarding high-dose chemotherapy. The term of DI is more useful in its principle than in the significance of its calculated value. (authors). 19 refs., 3 tabs., 3 figs

    Full Text Available Recent evidence indicates that antimicrobial peptides (AMPs serve key roles in defending the urinary tract against invading uropathogens. To date, the individual contribution of AMPs to urinary tract host defense is not well defined. In this study, we identified Regenerating islet-derived 3 gamma (RegIIIγ as the most transcriptionally up-regulated AMP in murine bladder transcriptomes following uropathogenic Escherichia coli (UPEC infection. We confirmed induction of RegIIIγ mRNA during cystitis and pyelonephritis by quantitative RT-PCR. Immunoblotting demonstrates increased bladder and urinary RegIIIγ protein levels following UPEC infection. Immunostaining localizes RegIIIγ protein to urothelial cells of infected bladders and kidneys. Human patients with UTI have increased urine concentrations of the orthologous Hepatocarcinoma-Intestine-Pancreas / Pancreatitis Associated Protein (HIP/PAP compared to healthy controls. Recombinant RegIIIγ protein does not demonstrate bactericidal activity toward UPEC in vitro, but does kill Staphylococcus saprophyticus in a dose-dependent manner. Kidney and bladder tissue from RegIIIγ knockout mice and wild-type mice contain comparable bacterial burden following UPEC and Gram-positive UTI. Our results demonstrate that RegIIIγ and HIP/PAP expression is induced during human and murine UTI. However, their specific function in the urinary tract remains uncertain.

    2017-09-01

    Full Text Available Co-evolutionary processes in plant–pathogen/herbivore systems indicate that protease inhibitors have a particular value in biotic interactions. However, little is known about the defensive role of their targets, the plant proteases. C1A cysteine proteases are the most abundant enzymes responsible for the proteolytic activity during different processes like germination, development and senescence in plants. To identify and characterize C1A cysteine proteases of barley with a potential role in defense, mRNA and protein expression patterns were analyzed in response to biotics stresses. A barley cysteine protease, HvPap-1, previously related to abiotic stresses and grain germination, was particularly induced by flagellin or chitosan elicitation, and biotic stresses such as the phytopathogenic fungus Magnaporthe oryzae or the phytophagous mite Tetranychus urticae. To elucidate the in vivo participation of this enzyme in defense, transformed barley plants overexpressing or silencing HvPap-1 encoding gene were subjected to M. oryzae infection or T. urticae infestation. Whereas overexpressing plants were less susceptible to the fungus than silencing plants, the opposite behavior occurred to the mite. This unexpected result highlights the complexity of the regulatory events leading to the response to a particular biotic stress.

    Objective was to improve the diagnosis of cervical neoplasia by early detection of human papillomavirus (HPV) in uterine cervix, by adding molecular testing of HPV using hybrid capture 2 (HC2) and polymerase chain reaction (PCR) tests to Papanicoalou (Pap) test. One hundred women were enrolled in this study. The mean age (mean+-SD) was 41.97+- 8.76 years and range was 27-65 years. All women had undergone cervical cytological screening with cervical cytology, HPV DNA testing by HC2 and PCR, during the period from January to December 2006, at King Abdul-Aziz University Hospital (KAAUH) and King Fahd research Center, Jeddah, Saudi Arabia. The results were obtained by HC2 for detection of HPV were 5(5%) high-risk HPV, one low-risk HPV (1%) and 94(94%) negative cases. The PCR detected only 4(4%) cases. Using the HC2 test as a reference, sensitivity, specificity, positive predictive, negative predictive values and accuracy of base line Pap were 50, 85, 17.7, 96.4 and 83%; of final Pap smear were 100, 96.8, 66.7, 100, and 97% and for PCR were 66.7, 100, 100, 97.9 and 98%. The Pap test was repeated within a year for patients with abnormal Pap test with positive HPV DNA. Combined screening by cytology and HPV testing using both HC2 and PCR sensitively detects women with existing disease. The absence of HPV DNA provides reassurance that patients are unlikely to develop cancer for several years. We suggest using Pap with HC2 and PCR in screening programs to ensure that women with the double negative result at baseline might safely be screened at longer intervals. (author)

    There is strong evidence that inadequate physical activity (PA) leads to an increased risk of lifestyle-related diseases and premature mortality. Physical activity on prescription (PAP) is a method to increase the level of PA of patients in primary care, but needs further evaluation. The aim of this observational study was to explore the association between PAP-treatment and the PA level of patients with metabolic risk factors and the relationship between changes in the PA level and health outcomes at the 6 month follow-up. This study included 444 patients in primary care, aged 27-85 years (56% females), who were physically inactive with at least one component of metabolic syndrome. The PAP-treatment model included: individualized dialogue concerning PA, prescribed PA, and a structured follow-up. A total of 368 patients (83%) completed the 6 months of follow-up. Of these patients, 73% increased their PA level and 42% moved from an inadequate PA level to sufficient, according to public health recommendations. There were significant improvements (p≤ 0.05) in the following metabolic risk factors: body mass index, waist circumference, systolic blood pressure, fasting plasma glucose, cholesterol, and low density lipoprotein. There were also significant improvements regarding health-related quality of life, assessed by the Short Form 36, in: general health, vitality, social function, mental health, role limitation-physical/emotional, mental component summary, and physical component summary.

    Full Text Available There is strong evidence that inadequate physical activity (PA leads to an increased risk of lifestyle-related diseases and premature mortality. Physical activity on prescription (PAP is a method to increase the level of PA of patients in primary care, but needs further evaluation. The aim of this observational study was to explore the association between PAP-treatment and the PA level of patients with metabolic risk factors and the relationship between changes in the PA level and health outcomes at the 6 month follow-up. This study included 444 patients in primary care, aged 27-85 years (56% females, who were physically inactive with at least one component of metabolic syndrome. The PAP-treatment model included: individualized dialogue concerning PA, prescribed PA, and a structured follow-up. A total of 368 patients (83% completed the 6 months of follow-up. Of these patients, 73% increased their PA level and 42% moved from an inadequate PA level to sufficient, according to public health recommendations. There were significant improvements (p≤ 0.05 in the following metabolic risk factors: body mass index, waist circumference, systolic blood pressure, fasting plasma glucose, cholesterol, and low density lipoprotein. There were also significant improvements regarding health-related quality of life, assessed by the Short Form 36, in: general health, vitality, social function, mental health, role limitation-physical/emotional, mental component summary, and physical component summary. Regression analysis showed a significant association between changes in the PA level and health outcomes. During the first 6-month period, the caregiver provided PAP support 1-2 times. This study indicates that an individual-based model of PAP-treatment has the potential to change people's PA behavior with improved metabolic risk factors and self-reported quality of life at the 6 month follow-up.

    Full Text Available Abnormal uterine bleeding is a serious problem among women of late reproductive age. Cervical cancer is one of the reasons of AUB and Pap smear is the best way to diagnose it. Blood has negative effects on Pap smear especially in AUB with great blood. One of the effective solutions for lysing RBC is Carnoy’s. This study aims to compare two methods of fixation in bloody Pap smear by Carnoy’s and normal spray in samples from women with AUB. This study was done on 204 bloody Pap smear from 102 women with AUB that referred to Zeinabieh and Faghihi hospitals of Shiraz University of Medical Sciences from2012-2013. After observing uterine bleeding in each subject, two samples were provided using usual Pap smear method; one of the slides was fixed by normal spray and the other slide fixed by Carnoy’s solution for20 minutes. After staining (Papanicolaou method, two pathologists performed a double-blind trial to analyze them. Data analysis was done using SPSS. 82 samples did not have cell adequacy. Squamous cells in Carnoy’s-fixed slides were more than spray-fixed ones (p=0.024. The decrease in the number of RBC on slides and the increase in the clarity of slides in Carnoy’s-fixed samples were more than sprayfixed slides (p=0.001, while identifying inflammatory cells(p=0.832 and microbial factors (p=1 in both methods showed no significant difference. Carnoy’s solution can be used as an effective fixative in bloody Pap smear from women with abnormal uterine bleeding.

    Full Text Available Carrion' disease, caused by Bartonella bacilliformis, remains truly neglected due to its focal geographical nature. A wide spectrum of clinical manifestations, including asymptomatic bacteremia, and lack of a sensitive diagnostic test can potentially lead to a spread of the disease into non-endemic regions where competent sand fly vectors may be present. A reliable test capable of detecting B. bacilliformis is urgently needed. Our objective is to develop a loop-mediated isothermal amplification (LAMP assay targeting the pap31 gene to detect B. bacilliformis.The sensitivity of the LAMP was evaluated in comparison to qPCR using plasmid DNA containing the target gene and genomic DNA in the absence and presence of human or sand fly DNA. The detection limit of LAMP was 1 to 10 copies/µL, depending on the sample metrics. No cross-reaction was observed when testing against a panel of various closely related bacteria. The utility of the LAMP was further compared to qPCR by the examination of 74 Lutzomyia longipalpis sand flies artificially fed on blood spiked with B. bacilliformis and harvested at days (D 1, 3, 5, 7 and 9 post feeding. Only 86% of sand flies at D1 and 63% of flies at D3 were positive by qPCR. LAMP was able to detect B. bacilliformis in all those flies confirmed positive by qPCR. However, none of the flies after D3 were positive by either LAMP or qPCR. In addition to demonstrating the sensitivity of the LAMP assay, these results suggest that B. bacilliformis cannot propagate in artificially fed L. longipalpis.The LAMP assay is as sensitive as qPCR for the detection of B. bacilliformis and could be useful to support diagnosis of patients in low-resource settings and also to identify B. bacilliformis in the sand fly vector.

    Full Text Available Background: Cervical carcinoma is a common cause of death in India. It is presented by spectrum of precancerous lesions, called cervical intraepithelial neoplasia (CIN. Cervical cytological screening is designed to detect over 90% of cytological abnormalities. It has been established that cervical cancers can be diagnosed at the pre-invasive stage with adequate, repetitive cytological screening. Keeping in view of the importance of cervical PAP abnormalities & by classifying them by Bethesda terminology; correlation with clinical findings & histopathological findings was done. Methods: All cervical Pap smears reported in Department of Pathology from 1st August 2015 to 31st July 2016, were prospectively studied and classified according to revised Bethesda terminology, 2014. Also cytoradiological and clinico-cytological, cytohistological correlation was studied. Results: Due to increasing awareness among masses inculcated by social workers, most of the patients for PAP smear cytology came for routine screening to rule out cervical lesions followed by clinical finding of per-vaginal discharge. The 350 screened patients were in the third and fourth decades of life. 99/350 cases were subjected to USG study, with maximum number of cases (34 cases showing normal study, followed by cases with ovarian cysts and fatty liver disease. Negative for intra-epithelial lesion (NILM without any denotable organism was the pre-dominant cytological finding of PAP smear study followed by cases of NILM with bacterial vaginosis (30 cases with two malignancies. Intra-epithelial lesions (IELs were noted in 16.86%. ASCUS comprised 12.29%, ASC-H comprised 1.14%, L-SIL comprised 1.71%, HSIL comprised 1.43%, Atrophic cervical smears comprised 5.14%, Squamous cell carcinoma comprised 0.29% cases. ASC/LSIL ratio was 7.8 and inadequacy rate for PAP smear study was 7.43%. Cytologyhistopathology correlation was possible in 62 cases. Conclusion: Classification of cervical PAP

Por outro lado, algumas variáveis foram mais freqüentemente observadas nas mulheres não submetidas ao exame de Papanicolaou: ter baixo nível socioeconômico, ter baixa escolaridade, ter baixa renda familiar e pertencer às faixas etárias mais jovens. CONCLUSÃO: os dados aqui apresentados apontam para desigualdades regionais na cobertura do exame de Papanicolaou na população feminina brasileira e para a necessidade de intervenção junto àqueles fatores a ela associados.PURPOSE: to present an overview of the coverage of the Pap smear in Brazil, emphasizing the determinant factors associated with failure of women to submit to the test. METHODS: the literature was reviewed using the LILACS (Latin-American and Caribbean Literature in Sciences of the Health, MEDLINE - 1966 to 2004 (International Literature in Sciences of the Health, PAHO (Collection of the Library of the Pan-American Organization of Health, and WHOLIS (System of Information of the Library of OMS databases. The review was enlarged through the search of bibliographical references of relevant studies, request for published and unpublished studies by specialists, and other sources. Articles that fulfilled the following criteria were selected: to be a cross-sectional study, carried out in Brazil, including information about periodicity of the Pap test (some time in life or in the last three years and/or containing information about factors associated with failure of women to submit to the test. Duplicates and articles without summary were excluded. A total of 13 articles fulfilling these criteria were selected. RESULTS: there are few studies on the coverage of Pap smear in Brazil. Most of them are concentrated in the big cities of the South and Southeast regions of the country. Besides the shortage, little methodological standardization exists in relation to the sampling and profile of the investigated women, which turns difficult the comparison among them

    smokers' group was 13.94%. Pulmonary emphysema was found in 34.6% of cases in the smokers' group: 33.3% former-smokers and 35.2% current-smokers. Emphysema was prevalent in the upper lobes (88.8%). Mean extension was 8.76% in the former smokers group and 18.81% in current-smokers, with a total mean extension of 15.47% in the smokers' group. Statistically, there was a significant difference between non-smokers and smokers as regards emphysema extension and expiratory air trapping (p=0.0034 and p=0.050 respectively). The smokers' group had a significantly wider diameter of the apical segmental bronchus of the right upper lobe than the controls. There was no significant statistical correlation between this dilatation and the emphysema score (r=0.051); p=0.81). The entity of smoking history did not correlate with emphysema extension or air trapping or with the size of the apical segmental bronchus of the right upper lobe. Conclusions: Our study demonstrates that HRCT is more sensitive and specific than commonly-used functional tests for the evaluation of initial emphysema in asymptomatic smokers. We observed expiratory air trapping only in the smokers' group, and only of the lobular type, without evidence of disease in inspiratory scans. Among the smokers and former-smokers, air trapping was found in 30.7% of subjects, with a mean extension lower than 10%. Our results therefore suggest that, even in asymptomatic subjects, expiratory air trapping is probably pathological and, once, bronchial asthma has been excluded, it may be related to cigarette smoking and indicate early inflammatory bronchiolar damage. HRCT may therefore be regarded as a useful tool in the early diagnosis of smoking-related lung disease.

    Full Text Available Famiglie in crisi, genitori assenti, distratti, tendenti alla delega che non fanno fronte alle proprie responsabilità, incapaci di porre limiti e regole ai propri figli: lo stereotipo negativo di “famiglia incapace di educare” sembra ormai consolidato e socialmente condiviso anche da parte di molti operatori dei servizi per la prima infanzia. Per evitare atteggiamenti giudicanti che possono ulteriormente indebolire il ruolo educativo delle famiglie ed ostacolare lo sviluppo di un rapporto di cooperazione, per evitare che si sviluppi sfiducia reciproca tra educatori/insegnanti e genitori, la presente ricerca è stata finalizzata a comprendere il punto di vista dei genitori su una serie di elementi caratterizzanti il “quotidiano dell’educazione” in famiglia. Con la rilevazione effettuata, tramite focus group e questionari, si è cercato di mettere a fuoco il punto di vista dei genitori, di bambini in età 0-6, su alcuni temi tra cui: cosa si inceppa e cosa ostacola l’esercizio delle funzioni normative da parte di padri e madri; il modo in cui vengono condivise le funzioni di cura nella coppia; le coordinate della rete sociale che può sostenere le famiglie nel loro compito; lo stato di salute della relazione educativa e le idee di “buona educazione” più diffuse.

This study showed that the ability of squamous intraepithelial lesion (SIL detection in spatula- first group (27 cases, 4.8%, was comparable to brush-first group (23 cases, 4.1%. Conclusions: Because reported SIL cases are higher when samples are first taken from exocervix and rate of blood contamination increases when samples are taken from endocervix (p=0.004, it is better to take samples first from exocervix for Pap Smear. This strategy increases the chance of diagnosis of cellular lesions of cervix.

    Anthocyanin pigments and associated flavonoids have demonstrated antioxidant properties and benefits for human health. Consequently, current plant bioengineers have focused on how to modify flavonoid metabolism in plants. Most of that research, however, does not consider the role of natural biotic stresses (e.g., herbivore attack). To understand the influence of herbivore attack on the metabolic engineering of flavonoids, we examined tobacco plants overexpressing the Arabidopsis PAP1 gene (encoding an MYB transcription factor), which accumulated anthocyanin pigments and other flavonoids/phenylpropanoids. In comparison to wild-type and control plants, transgenic plants exhibited greater resistance to Spodoptera litura. Moreover, herbivory suppressed the PAP1-induced increase of transcripts of flavonoid/phenylpropanoid biosynthetic genes (e.g., F3H) and the subsequent accumulation of these genes' metabolites, despite the unaltered PAP1 mRNA levels after herbivory. The instances of down-regulation were independent of the signaling pathways mediated by defense-related jasmonates but were relevant to the levels of PAP1-induced and herbivory-suppressed transcription factors, An1a and An1b. Although initially F3H transcripts were suppressed by herbivory, after the S. litura feeding was interrupted, F3H transcripts increased. We hypothesize that in transgenic plants responding to herbivory, there is a complex mechanism regulating enriched flavonoid/phenylpropanoid compounds, via biotic stress signals.

Moreover, herbivory suppressed the PAP1-induced increase of transcripts of flavonoid/phenylpropanoid biosynthetic genes (e.g., F3H) and the subsequent accumulation of these genes' metabolites, despite the unaltered PAP1 mRNA levels after herbivory. The instances of down-regulation were independent of the signaling pathways mediated by defense-related jasmonates but were relevant to the levels of PAP1-induced and herbivory-suppressed transcription factors, An1a and An1b. Although initially F3H transcripts were suppressed by herbivory, after the S. litura feeding was interrupted, F3H transcripts increased. We hypothesize that in transgenic plants responding to herbivory, there is a complex mechanism regulating enriched flavonoid/phenylpropanoid compounds, via biotic stress signals. PMID:25268129

    Bacillus subtilis SC-8 produces an antibiotic that has narrow antagonistic activity against bacteria in the Bacillus cereus group. In B. cereus group bacteria, peptide-activating PlcR (PapR) plays a significant role in regulating the transcription of virulence factors. When B. subtilis SC-8 and B. cereus are co-cultured, PapR is assumed to stimulate antibiotic production by B. subtilis SC-8. To better understand the effect of PapR on this interspecies interaction, the global transcriptome profile of B. subtilis SC-8 was analyzed in the presence of PapR. Significant changes were detected in 12.8 % of the total transcripts. Genes related to amino acid transport and metabolism (16.5 %) and transcription (15 %) were mainly upregulated, whereas genes involved in carbohydrate transport and metabolism (12.7 %) were markedly downregulated. The expression of genes related to transcription, including several transcriptional regulators and proteins involved in tRNA biosynthesis, was increased. The expression levels of genes associated with several transport systems, such as antibiotic, cobalt, and iron complex transporters, was also significantly altered. Among the downregulated genes were transcripts associated with spore formation, the subtilosin A gene cluster, and nitrogen metabolism.

    Full Text Available Healthcare in Thailand is not equally distributed, and not all people can equally access healthcare resources even if they are covered by health insurance. To examine factors associated with the utilization of mammography examination for breast cancer and Pap smear screening for cervical cancer, data from the national reproductive health survey conducted by the National Statistical Office of Thailand in 2009 was examined. The survey was carried out on 15,074,126 women aged 30-59 years. The results showed that the wealthier respondents had more mammograms than did the lower-income groups. The concentration index was 0.144. The data on Pap smears for cervical cancer also showed that the wealthier respondents were more likely to have had a Pap smear than their lower-income counterparts. The concentration index was 0.054. Determinants of mammography examination were education, followed by health welfare and wealth index, whereas the determinants of Pap smear screening were wealth index, followed by health welfare and education. The government should support greater education for women because education was associated with socioeconomic status and wealth. There should be an increase in the number of screening campaigns, mobile clinics, and low-cost mammograms and continued support for accessibility to mammograms, especially in rural areas and low-income communities.

    Human semen is principal vehicle for transmission of HIV-1 and other enveloped viruses. Several endogenous peptides present in semen, including a 39-amino acid fragments of prostatic acid phosphatase (PAP248-286) assemble into amyloid fibrils named as semen-derived enhancer of viral infection (SEVI) that promote virion attachment to target cells which dramatically enhance HIV virus infection by up to 105-fold. Epigallocatechin-3-gallate (EGCG), a polyphenolic compound, is the major catechin found in green tea which disaggregates existing SEVI fibers, and inhibits the formation of SEVI fibers. The aim of this study was to screen a number of relevant polyphenols to develop a rational approach for designing PAP248-286 aggregation inhibitors as potential anti-HIV agents. The molecular docking based virtual screening results showed that polyphenolic compounds 2-6 possessed good docking score and interacted well with the active site residues of PAP248-286. Amino acid residues of binding site namely; Lys255, Ser256, Leu258 and Asn265 are involved in binding of these compounds. In silico ADMET prediction studies on these hits were also found to be promising. Polyphenolic compounds 2-6 identified as hits may act as novel leads for inhibiting aggregation of PAP248-286 into SEVI.

    In questo scritto un’intuizione storica limpida e penetrante, con la quale il giovane Einstein pose le basi per i successivi studi sulla teoria della relatività, è consegnata al lettore in forma chiara ed essenziale. Nel 1905, appena ventiseienne, Einstein intervenne nel dibattito sulle leggi di distribuzione della radiazione luminosa che all’epoca animava gli ambienti scientifici e che si inseriva nel più ampio processo di revisione delle scienze fisiche e naturali. Il giovane scienziato tentò di dimostrare come «...una radiazione monocromatica di densità ridotta... si comporta, per quanto riguarda la termodinamica, come se fosse composta da quanti di energia indipendenti l’uno dall’altro». In altre parole, nel caso limite di basse temperature e piccole lunghezze d’onda, la teoria ondulatoria della luce, tradizionalmente accettata e riconosciuta dai fisici, sembrava destituita di ogni fondamento, e si faceva strada l’ipotesi che la radiazione viaggiasse “a pacchetti”. Lo sviluppo succe...

    Full Text Available Abstrak: Dalam konteks pendidikan istilah dualisme dan dikotomi memiliki makna yang sama yaitu pemisahan antara pendidikan umum dari pendidikan agama. Dikotomi selalu melahirkan pandangan pembedaaan di satu sisi dan penyamaaan di sisi yang lain. Pandangan dikotomis pada hakikatnya mengabaikan esensi atau nilai sprit pendidikan. Membedakan dan menyamakan lebih dimaknai pada ta-taran permukaan sehingga jelas merusak nilai spirit dari pendidikan Islam. Dua-lisme dan dikotomi bukan hanya pada tataran pemilahan, tetapi telah masuk pada wilayah pemisahan yang dalam operasionalnya memisahkan mata pelajaran umum dari mata pelajaran agama, sekolah umum dan madrasah yang penge-lolaannya berjalan terpisah-pisah. Puncaknya pada pemerintah Orde Baru yang mengeluarkan melalui Surat Keputusan Bersama (SKB pada tanggal 24 Maret 1975 yang menguatkan pemisahan itu hingga saat ini. Dampaknya terasa meru-gikan dan makna Islam menjadi sempit karena pengotak-kotakan ilmu akhirnya menomorduakan dan menganaktirikan pendidikan Islam.

    Polyfluoroalkyl phosphate mono-, di-, and tri-esters (mono-, di-, and triPAPs) are used to water- and grease-proof food packaging materials, and these chemicals are known precursors to perfluoroalkyl carboxylic acids (PFCAs). Existing analytical methods for PAPs lack sample clean-up steps in the sample preparation. In the present study, a method based on ultra performance liquid chromatography coupled to tandem mass spectrometry (UPLC/MS/MS) was developed and optimized for the analysis of mono-, di-, and triPAPs, including a clean-up step for the raw extracts. The method was applied to food samples and their PAP-containing packaging materials. The optimized UPLC/MS/MS method enabled the separation and identification of a total of 4 monoPAPs, 16 diPAPs, and 7 triPAPs in the technical mixture Zonyl®-RP. For sample clean-up, weak anion exchange solid phase extraction columns were tested. PAPs standard solutions spiked onto the columns were separated into a fraction containing neutral compounds (triPAPs) and a fraction with ionic compounds (mono- and diPAPs) with recoveries between 72-110%. Method limits of quantification for food samples were in the sub to low picogram per gram range. For quantitative analysis of PAPs, compound-specific labeled internal standards showed to be essential as sorption and matrix effects were observed. Mono-, di-, and/or triPAPs were detected in all food packaging materials obtained from the Swedish market. Up to nine diPAPs were detected in the food samples, with the 6:2/6:2 and 6:2/8:2 diPAPs as the dominant compounds. DiPAP concentrations in the food samples ranged from 0.9 to 36 pg/g, which was comparable to individual PFCA concentrations in the same samples. Consumption of food packed in PAP-containing materials could be an indirect source of human exposure to PFCAs.

    Cervical screening by means of annual Papanicolaou (PAP) smears has been recommended for all women living with HIV. We analysed the results of our annual PAP smear screening program to identify low-risk subgroups for less rigorous screening. The study comprised 369 women followed at the Helsinki University Hospital 2002-2013, with a total of 2033 PAP smear results. We analyzed the temporal changes in PAP smear findings. Logistic regression analysis for binominal dependent variables was used for assessing risk factors for ever having cytological squamous intraepithelial lesions (hereafter referred as SIL) using generalized estimating equations taking into account multiple observations of each patient. Most women had well-controlled HIV, especially towards the end of the study. PAP smear results improved substantially. At the time of each individual's last PAP smear, 90.0% of the findings displayed normal results. Conversely, the rate of SIL decreased from 16.8% to 4.6% from 2002 to 2013. In multivariate analysis the risk of SIL was significantly lower in women with consecutive normal PAP smear findings during the first two years of follow up [odds ratio (OR) 0.21, 95% confidence interval (CI) 0.10-0.45, p 500 cells/μL (OR 0.11, 95% CI 0.05-0.26, p < 0.001). Widespread use of combination antiretroviral therapy (cART) and systematic cervical screening has reduced the rate of abnormal PAP smears. It seems feasible to identify low-risk women by combining HIV-related information and PAP smear results. Screening low-risk women living with HIV at three-year intervals similar to HIV-negative women appears justified. © 2017 Nordic Federation of Societies of Obstetrics and Gynecology.

    La teoria della Relatività Generale ha la duplice funzione di descrivere la gravitazione come fenomeno fisico in sé e di fornire al contempo un algoritmo adeguato a descrivere tutte le altre leggi della fisica in presenza di gravitazione, sia essa reale o semplicemente indotta da uno stato di accelerazione. A tale scopo la teoria si presenta con una struttura matematica molto elaborata che richiede come requisito indispensabile conoscenze di geometria differenziale e di calcolo differenziale assoluto. La maggiore difficoltà nell'uso della teoria è riconoscere il legame fra la sua struttura formale e i fenomeni fisici che essa descrive, potendo in tal modo procedere alla loro verificabilità sperimentale. Gli esercizi sono essenziali al raggiungimento di tale obiettivo; lo scopo del libro pertanto è quello di fornire a studenti e cultori della materia una guida all'applicazione dei concetti teorici della Relatività Generale a una vasta gamma di situazioni fisiche.

    ABSTRACT

    The chaperone/usher pathway is used by Gram-negative bacteria to assemble adhesive surface structures known as pili or fimbriae. Uropathogenic strains ofEscherichia coliuse this pathway to assemble P and type 1 pili, which facilitate colonization of the kidney and bladder, respectively. Pilus assembly requires a periplasmic chaperone and outer membrane protein termed the usher. The chaperone allows folding of pilus subunits and escorts the subunits to the usher for polymerization into pili and secretion to the cell surface. Based on previous structures of mutant versions of the P pilus chaperone PapD, it was suggested that the chaperone dimerizes in the periplasm as a self-capping mechanism. Such dimerization is counterintuitive because the chaperone G1 strand, important for chaperone-subunit interaction, is buried at the dimer interface. Here, we show that the wild-type PapD chaperone also forms a dimer in the crystal lattice; however, the dimer interface is different from the previously solved structures. In contrast to the crystal structures, we found that both PapD and the type 1 pilus chaperone, FimC, are monomeric in solution. Our findings indicate that pilus chaperones do not sequester their G1 β-strand by forming a dimer. Instead, the chaperones may expose their G1 strand for facile interaction with pilus subunits. We also found that the type 1 pilus adhesin, FimH, is flexible in solution while in complex with its chaperone, whereas the P pilus adhesin, PapGII, is rigid. Our study clarifies a crucial step in pilus biogenesis and reveals pilus-specific differences that may relate to biological function.

    IMPORTANCEPili are critical virulence factors for many bacterial pathogens. UropathogenicE. colirelies on P and type 1 pili assembled by the chaperone/usher pathway to

    O 6 -Methylguanine (O 6 -MeG) is highly mutagenic and is commonly found in DNA exposed to methylating agents, generally leads to G:C to A:T mutagenesis. To study DNA replication encountering O 6 -MeG by the DNA polymerase (gp90) of P. aeruginosa phage PaP1, we analyzed steady-state and pre-steady-state kinetics of nucleotide incorporation opposite O 6 -MeG by gp90 exo - . O 6 -MeG partially inhibited full-length extension by gp90 exo - . O 6 -MeG greatly reduces dNTP incorporation efficiency, resulting in 67-fold preferential error-prone incorporation of dTTP than dCTP. Gp90 exo - extends beyond T:O 6 -MeG 2-fold more efficiently than C:O 6 -MeG. Incorporation of dCTP opposite G and incorporation of dCTP or dTTP opposite O 6 -MeG show fast burst phases. The pre-steady-state incorporation efficiency (k pol /K d,dNTP ) is decreased in the order of dCTP:G>dTTP:O 6 -MeG>dCTP:O 6 -MeG. The presence of O 6 -MeG at template does not affect the binding affinity of polymerase to DNA but it weakened their binding in the presence of dCTP and Mg 2+ . Misincorporation of dTTP opposite O 6 -MeG further weakens the binding affinity of polymerase to DNA. The priority of dTTP incorporation opposite O 6 -MeG is originated from the fact that dTTP can induce a faster conformational change step and a faster chemical step than dCTP. This study reveals that gp90 bypasses O 6 -MeG in an error-prone manner and provides further understanding in DNA replication encountering mutagenic alkylation DNA damage for P. aeruginosa phage PaP1.

    Full Text Available Desa Xuan Tun di Kecamatan Van Ninh Kota Nha Trang Provinsi Khanh Hoa merupakan lokasi pertama kegiatan budidaya lobster di Vietnam yang dilakuan pada tahun 1992. Secara umum di Kota Nha Trang, ada tiga jenis lobster yang dibudidayakan yaitu lobster mutiara (Panulirus ornatus, lobster pasir (Panulirus homarus, dan lobster batik (Panulirus longipes, karena benih lobster tersebut mudah didapat pada awalnya, cepat tumbuh, berukuran besar, warna cerah, dan memiliki harga yang tinggi. Kegiatan budidaya lobster pada dasarnya terdiri atas: penangkapan benih lobster, produksi tokolan lobster, dan pembesaran lobster yang masing-masing merupakan segmen usaha tersendiri. Pakan yang digunakan dalam produksi tokolan dan pembesaran lobster adalah berupa udang, kerang, tiram, cumi-cumi, dan ikan rucah, di mana sebagian besar dari pakan tersebut digunakan ikan rucah terutama pada pembesaran lobster. Sebagai akibat penggunaan pakan tersebut dan peningkatan jumlah keramba jaring apung yang cukup signifikan berdampak pada penurunan kualitas perairan yang memicu berkembangya penyakit susu (milky haemolymph disease sehingga terjadi penurunan produksi. Terkait dengan hasil yang didapatkan tersebut, ke depan diperlukan berbagai kegiatan termasuk untuk dapat diaplikasikan di Indonesia. Kegiatan tersebut meliputi: produksi benih lobster secara buatan di hatcheri dan penggunaan pakan buatan berupa moist pellet. Upaya pencegahan penyakit susu dan perlakuan-perlakuan praktis untuk mencegah perkembangan serangan penyakit susu juga perlu mendapat perhatian. Perkembangan budidaya lobster yang begitu cepat memicu terjadinya penurunan daya dukung lahan. Oleh karena itu, kegiatan untuk menentukan daya dukung lahan dan kesesuaian lahan menjadi penting untuk dilakukan untuk menentukan lokasi dan jumlah keramba jaring apung yang dapat dioperasikan. Penentuan daya dukung lahan dan evaluasi kesesuaian lahan tidak hanya dilakukan pada daerah yang

    Full Text Available Uno dei concetti su cui mi piace riflettere è quello della velocità. Più precisamente se sia possibile connettere l’intelligenza alla velocità. Oggi è necessario essere veloci e il vivere velocemente ha conquistato la quotidianità confondendosi strategicamente con la nozione di intelligenza. Le coordinate della surmodernità: l’accelerazione della storia, il restringimento dello spazio e l’individualizzazione dei destini pare abbiano imposto la velocità come conditio sine qua non sia improbabile conquistare un dignitoso ruolo sociale. Velocità come chiave di accesso, password obbligatoria, condizione connettiva con cui l’io finalmente accede all’attuale e soprattutto intelligente modo di vivere. La mia riflessione si concentrerà sull’esempio di lentezza proposto dai barboni, da ora in poi definiti diasporici metropolitani. Velocità vs lentezza, dunque, per una riflessione sulle contemporanee dinamiche del vivere metropolitano. Mi soffermerò su sensazioni, emozioni, ricordi e principalmente dubbi, per articolare una prima critica dell’equazione normativa “velocità uguale intelligenza” nonché per mostrare un esempio di resistenza, un modello altro in opposizione da quello dominate.

    Full Text Available A partire dagli anni Duemila, il fenomeno delle cosiddette risorgenze dialettali si è manifestato, nel panorama linguistico italiano, anche attraverso l’emergenza dei dialetti negli ambiti propri della Comunicazione Mediata dal Computer e, specialmente, sui siti internet creati ‘dal basso’, come l’enciclopedia libera e multilingue online Wikipedia. In questo articolo, si esaminerà il lascito di Cherubini e del suo Vocabolario milanese-italiano sull’edizione regionale lombarda della Wikipedia: gli articoli di quest’ultima saranno passati in rassegna, sia dal punto di vista ortografico, comparando le scelte del lessicografo milanese con quelle più in voga online, sia dal punto di vista morfo-sintattico, discutendo in questo secondo caso la presenza e la produttività di alcuni verbi sintagmatici. What remains of Cherubini today? Two case studies Since the beginning of the twenty-first century, the phenomenon of dialect resurgence has manifested in Italy through the emergence of dialects in Computer Mediated Communication, especially, on bottom-up created Web sites, like the free, multilingual, online encyclopedia Wikipedia. In this article, we will examine the legacy of Cherubini and his Milanese-Italian dictionary on the regional Lombard version of Wikipedia. We will review the articles both in terms of spelling, comparing the choices of Milanese lexicographer with those most utilized currently online, and from a morpho-syntactic point of view, discussing the presence and the productivity of some phrasal verbs.

  5. Studio del comportamento di Acanthamoeba. polyphaga in presenza di Legionella pneumophila e di altri batteri ad habitat acquatico

    2003-05-01

    Full Text Available Le amebe a vita libera sono state oggetto di diversi studi negli ultimi anni, non solo per le loro potenzialità patogene nei confronti dell’uomo, ma anche per l’importante ruolo che svolgono in natura, dove agiscono come predatori in grado di controllare le popolazioni batteriche. Alcuni degli organismi fagocitati però possono evitare la lisi fagosomiale e mantenere la loro condizione vitale a livello intracellulare, divenendo endosimbionti. Le amebe fungono così da riserva per questi batteri, proteggendoli da difficili condizioni extracellulari e provvedendo ad un ambiente consono alla loro replicazione. Tale tipo di interazione è particolarmente studiata in Legionella pneumophila, dal momento che l’ampia diffusione di questo germe, nonché la sua virulenza, pare siano fortemente influenzate dalla capacità di parassitare protozoi appartenenti ai generi Acanthamoeba, Naegleria e Balamuthia. Al fine di ottenere maggiori informazioni sui fattori favorenti o inibenti lo sviluppo di questi protozoi, è stato studiato il comportamento di un ceppo di Acanthamoeba polyphaga coltivato, in solido e in liquido, in associazione con L. pneumophila ed altri batteri ad habitat acquatico (Pseudomonas, Aeromonas, Achromobacter, Burkholderia. Su tappeti di cellule batteriche allestiti in Non Nutrient Agar (NNA, A.polyphaga si è mostrata in grado di moltiplicarsi utilizzando come nutrimento tutti i ceppi testati, nonostante alcuni, come Burkholderia cepacia SSV6 e Achromobacter xylox SS28, risultino più idonei al suo sviluppo. In piastre a pozzetti addizionate di acqua condottata autoclavata, il protozoo ha mostrato una buona capacità di sopravvivenza, non risultando inoltre influenzato dalla presenza di legionella o dei batteri acquatici testati. Dal momento che, fra i batteri descritti come capaci di vita intra-amebica, sono inclusi patogeni quali Chlamydia, Legionella, Listeria e Rickettsiae, risulta necessario riconsiderare la rilevanza clinica

    In the last years there has been an increasing interest on IORT (Intraoperative Radiation Therapy), also because of the development of dedicated accelerators. This technique represents a very effective oncological treatment consisting in delivering a single high dose on a tumour bed soon after surgery resection. In the following we present the proposal of development of a last generation IORT system based on the use of a linear accelerator with variable energy in the range 3-15 MeV, operating in C band (5712 MHz). Respect to the accelerator used in the commercial IORT systems operating at a typical frequency of 2998 MHz (S band) limited to a maximum energy of 12 MeV, the use of a higher RF frequency allows an increase of the maximum energy. This extends the use of the IORT technique to a wider field of tumors and an improvement of the system in terms of compactness and weight reduction. In addition the machine will be provided with a devoted absolute dosimetry system that will strongly simplify the procedures of dosimetric characterization.

    To determine the knowledge and practice of cervical cancer screening among practicing female nurses with a view to sensitizing them as a first step towards increasing screening uptake in the community. A self administered questionnaire survey of all the female nurses working in Nnamdi Azikiwe university Teaching Hospital Nnewi center. 144 out of 166 questionnaires were correctly completed and returned. 122 (87%) were aware of the existence of screening services. Although 9.3% had lost relations to cancer of the cervix, only 5.7% had ever undergone a pap smear. While 52 (37.1%) had no reason for not screening, 21 (15%) were afraid of the possible outcome and 35 (25%) felt they were not likely candidates for cancer of the cervix. knowledge of cervical cancer screening services among female nurses in Nnewi is high while uptake rate is abysmally poor. There is need to further educate the nurses who will play a major role in enlightening the public on the availability and need for cervical screening services.

    2015-01-01

    Five lines of transgenic tobacco over-expressing Production of Anthocyanin Pigment 1 (PAP1) cDNA were analysis of metabolic response against the radiation and their protection of the plant under tissue culture condition. PAP1 transgenic and wild type (WT) plants were treated with the radiations of photosynthetically activate radiation (PAR) or PAR combined with UV-A. All lines of transgenic significantly increased in amounts of p-coumaric acid, naringenin apigenin more than WT under both treatments. Additional UV-A radiating to plant rose up kaempferol content in WT plant (1.5 times) and in PAP1 transgenics (1.8 times). These transgenic plants treated under both conditions had also increased anthocyanin substances (pelargonidin) with significant value after compared to WT. Content of total soluble sugar (TSS) was related to the content of total flavonoids in transgenic. PAR combined with UV-A had a lower induction of the electrolyte leakage percentage and malondialdehyde (MDA) level in the transgenic leaf tissue compared to WT tissue. The metabolic substance levels were considered on its protection of plant cells. In transgenic tissue, the enhancement of apigenin level strongly diminished the increase level of electrolyte leakage while the levels of TSS, p-coumaric acid and naringinin less affected. Moreover, the increase levels of kaempferol and pelargonidin associated with the decrease level of MDA, while the TSS level reversely responded. The PAP1 transgenic increased response of light by adaptation of their metabolites (TSS, p-coumaric acid and flavonoids) consequently enhance parameter indicating protections of the cell. (author)

  3. A cathepsin F-like peptidase involved in barley grain protein mobilization, HvPap-1, is modulated by its own propeptide and by cystatins

    Science.gov (United States)

    Diaz, Isabel

    2012-01-01

    Among the C1A cysteine proteases, the plant cathepsin F-like group has been poorly studied. This paper describes the molecular and functional characterization of the HvPap-1 cathepsin F-like protein from barley. This peptidase is N-glycosylated and has to be processed to become active by its own propeptide being an important modulator of the peptidase activity. The expression pattern of its mRNA and protein suggest that it is involved in different proteolytic processes in the barley plant. HvPap-1 peptidase has been purified in Escherichia coli and the recombinant protein is able to degrade different substrates, including barley grain proteins (hordeins, albumins, and globulins) stored in the barley endosperm. It has been localized in protein bodies and vesicles of the embryo and it is induced in aleurones by gibberellin treatment. These three features support the implication of HvPap-1 in storage protein mobilization during grain germination. In addition, a complex regulation exerted by the barley cystatins, which are cysteine protease inhibitors, and by its own propeptide, is also described PMID:22791822

    neste último método propedêutico. Os diagnósticos de tricomoníase observados em ambos os métodos citológicos (3,7 e 2,7% traduzem a baixa prevalência destes parasitas na gestação. O cálculo do índice kappa para avaliação da concordância entre os dois procedimentos citológicos nos diversos achados microbiológicos demonstrou baixa correlação nos diagnósticos da vaginose bacteriana e colpites bacterianas inespecíficas, bem como na identificação da flora vaginal normal. CONCLUSÕES: embora a citologia corada apresente melhor acurácia no diagnóstico de fungos não formadores de micélios, a citologia direta a fresco demonstrou ser melhor avaliador dos elementos não epiteliais dos esfregaços vaginais. Entretanto, a microscopia corada pela técnica de Papanicolaou, por permitir melhor apreciação das células epiteliais cervicovaginais, representa o mais importante instrumento revelador das agressões e reações nucleocitoplasmáticas.PURPOSE: to analyze vaginal contents using the fresh wet mount of a cytological exam in the first prenatal visit of women with or without genital complaints and correlate the conclusion with the results from the Pap smears. Microscopy during pregnancy should be valued and recognized as a method capable of providing immediate diagnosis in 90% of bacterial vaginosis, candidiasis and trichomoniasis cases. METHODS: a prospective study was performed in 216 pregnant women selected from the prenatal department of a public hospital, between October 30, 2001 and November 12, 2002. Two samples were collected from the posterior vaginal vault and deposited onto two separate microscope slides. To one slide, a droplet of 0.9% NaCl was applied and to the other, a droplet of 10% KOH. Both slides were covered with a coverslip for immediate microscopic evaluation. Tests were perfomed in one drop of the material to examine pH and whiff. The microscopic examination of the material was carried out at a 100X, 400X and exceptionally 1000X

A pesquisa caracteriza-se como exploratória, sendo que no aspecto da abordagem do problema, o trabalho foi desenvolvido em duas fases: uma qualitativa exploratória e outra quantitativa descritiva por meio da análise de variância com aplicação do teste ANOVA. Investigaram-se os efeitos do framing positivo versus o framing negativo, na mensagem transmitida, através de textos que compõem o questionário respondido pelos entrevistados. O questionário foi aplicado a investidores mineiros composto por clientes de uma corretora de valores de Belo Horizonte, bem como professores da área de finanças que ministram disciplinas da área de mercado de capitais em universidades de Belo Horizonte. Neste estudo a maioria dos entrevistados do grupo framing positivo é do sexo masculino, com faixa etária acima de 40 anos. Demonstrou-se que a mensagem estruturada positivamente (enfatizando os ganhos da prevenção ao risco foi mais persuasiva do que a mensagem estruturada negativamente (enfatizando as perdas da não prevenção ao risco e do que a mensagem informativa (do grupo controle. A hipótese de que a informação positiva tem maior impacto do que a informação negativa equivalente vai de encontro com as propriedades da função valor da Teoria dos Prospects. Conclui-se, portanto, que um determinado investidor, munido de informações de caráter positivo, enfatizando os aspectos positivos da mensagem, sinta-se incentivado e superconfiante a investir em ações.

    Full Text Available Abstract Background Partly because of functional genomics, there has been a major paradigm shift from solely thinking of skeletal muscle as contractile machinery to an understanding that it can have roles in paracrine and endocrine functions. Physical inactivity is an established risk factor for some blood clotting disorders. The effects of inactivity during sitting are most alarming when a person develops the enigmatic condition in the legs called deep venous thrombosis (DVT or “coach syndrome,” caused in part by muscular inactivity. The goal of this study was to determine if skeletal muscle expresses genes with roles in hemostasis and if their expression level was responsive to muscular inactivity such as occurs in prolonged sitting. Methods Microarray analyses were performed on skeletal muscle samples from rats and humans to identify genes associated with hemostatic function that were significantly expressed above background based on multiple probe sets with perfect and mismatch sequences. Furthermore, we determined if any of these genes were responsive to models of physical inactivity. Multiple criteria were used to determine differential expression including significant expression above background, fold change, and non-parametric statistical tests. Results These studies demonstrate skeletal muscle tissue expresses at least 17 genes involved in hemostasis. These include the fibrinolytic factors tetranectin, annexin A2, and tPA; the anti-coagulant factors TFPI, protein C receptor, PAF acetylhydrolase; coagulation factors, and genes necessary for the posttranslational modification of these coagulation factors such as vitamin K epoxide reductase. Of special interest, lipid phosphate phosphatase-1 (LPP1/PAP2A, a key gene for degrading prothrombotic and proinflammatory lysophospholipids, was suppressed locally in muscle tissue within hours after sitting in humans; this was also observed after acute and chronic physical inactivity conditions

    Full Text Available L'incontro trentino ha dimostrato l'interesse crescente dei giovani sociologi per lo sviluppo dei metodi narrativi e la capacità che questi hanno di essere efficaci nell'analisi di svariati temi, dai racconti di malattia alle narrazioni identitarie, dallo studio di lavoro e organizzazioni a quello delle migrazioni, di genere e memoria. Tuttavia, l'interesse della sociologia italiana va visto in un quadro di sviluppo più ampio a livello europeo e americano dove, a partire dagli anni '90, l'intervento di alcuni autori come Lyotard, Bruner e Macintyre, ha sancito quella che alcuni autori hanno definito svolta narrativa. La sociologia, infatti, tende sempre più a valorizzare la narrazione come processo di conoscenza peculiare che è attivato costantemente nella vita quotidiana; la "rivoluzione" risiede nel fatto che la narrazione diventa oggetto della sociologia e la disciplina stessa valorizza il suo uso sia come strumento di indagine scientifica, sia come modo di conoscere che come modo di comunicare, rivendicando la legittimità scientifica all'ascolto della parola diretta degli individui coinvolti all'interno delle ricerche di stampo sociologico.

Organoleptic analysis of the wines showed a greater appreciation for both of dessert wines. The best ratings were given for the olfactory characteristics (floral and fruity aromas and taste characteristics. In particular, the Greco bianco b. had excellent scores slightly lower than Malvasia di Lipari b. Therefore, the tested varieties have shown a good potential for the production of dessert wines related to typicality of the grape and the region. Dessert wines produced, have a complex flavor profile and interesting for the high acidic component, which improved the taste perception of wine and attenuated the sensation of sweetness. That feature could allow a good wine aging, too.

    Full Text Available La città di Perugia ha, fin dagli anni ’70, unito alla sua capacità di attrazione turistica, dovuta al patrimonio storico ambientale plurimillenario, una volontà di affrontare il tema della mobilità urbana in maniera profondamente innovativa ed ambientalmente sostenibile. Il concetto della creazione di parcheggi di attestazione, serviti da percorsi meccanizzati di risalita verso l’acropoli, è stato recentemente ampliato dalla creazione del Minimetro, mezzo di trasporto innovativo, dal ridottissimo impatto ambientale, che unisce in soli 12 minuti, con un servizio semicontinuo, l’area di valle di Pian di Massiano, dotata di un capace parcheggio da circa 2800 posti auto, al centro cittadino, servendo diversi quartieri urbani. Tale sistema di trasporto, corridoio forte del trasporto pubblico urbano, ha fornito lo spunto per attuare una nuova modalità di gestione dei flussi turistici, che individua nel Minimetro la modalità principale di accesso al centro storico sia per i gruppi a numero ridotto, sia per i gruppi organizzati in arrivo con i bus turistici. L’organizzazione della mobilità turistica che ne è derivata costituisce un ulteriore passo in avanti lungo quell’itinerario di gestione della città che cerca di coniugare l’attrattiva turistica, con le sue ricadute in termini di crescita economica, e la salvaguardia del patrimonio storico artistico e della qualità della vita dei cittadini. Gli scenari futuri vedono un’iniezione di tecnologia in questo contesto, con l’introduzione nella gestione dei flussi turistici dei concetti di accreditamento, dell’infomobilità come supporto alle politiche urbane, del controllo unito alla fornitura di servizi georeferenziati.

    Full Text Available Introduction: Co-testing performance for detection of high grade Cervical Intraepithelial Neoplasia (CIN has not been adequately addressed from Low Resource Countries (LRCs. Where isolated tests do not have adequate performance, further explorations are recommended. Aim: To evaluate the co-testing of conventional cervical screening tests such as Papanicolaou (Pap and Visual Inspection Cervix with Acetic Acid (VIA, with care HPV on Cervical Samples (CHPV or on Vaginal Samples (VHPV in the detection of high grade CIN. Materials and Methods: The cross-sectional study was conducted on ever married women of age 30 to 59 years in a rural community of Dadri. Women were screened by CHPV, VHPV, and Pap and VIA methods. Confirmation of screen positives was done by histology. Sensitivity, Specificity and likelihood ratios of different combinations of test determined to evaluate the performance. Results: Total eligible women, 66.2% (5032/7604 responded for screening. Analysis was performed on 4658, after excluding those who did not complete all screenings. Co-testing of CHPV (OR=246 or VHPV (OR=278 with Pap had highest association. Positive likelihood ratios of CHPV and VHPV with Pap in CIN II+ detection rates were 13.0 and 11.8 and in CIN III+ the detection rates were 18.0 and 16.0 respectively. Higher sensitivities and specificities were observed in co-testing for CIN III+ detection as against CIN II+ lesions. Conclusion: Choice of co-testing in a pair of tests for detection of high grade CIN is likely to depend on whether screening is targeted for developed or low resource country. VIA in isolation might not yield optimal results for LRCs.

    To determine the prevalence of abnormal cervical smears in a previously unscreened and asymptomatic population in Romania and to compare the data with those from other countries in Europe. In a retrospective study, data were reviewed from smears obtained from women in Romania who had been referred to the gynecologist between January 2006 and December 2011. The smears were collected through 3 regional opportunistic programs of cervical screening and were classified according to the Bethesda system. During the study period, 50536 smear tests were carried out. Of these, 100 smears (0.2%) were unsatisfactory and excluded from the study. Among the remaining 50436 smears, 2965 patients (5.9%) had abnormal epithelial changes. Most of the abnormal smears were represented by atypical squamous cells of undetermined significance (2.6% of all smears). The data confirmed that there is a high prevalence of high-grade intraepithelial squamous-type lesions (0.9% of all smears) in Romania, and of abnormal smears in women younger than 25years of age (14.0% of all abnormal smears). The data show that there is a high prevalence of epithelial abnormalities among cervical smears in Romania compared with other European countries that run a national screening program. © 2013.

    Full Text Available Stoccaggio e trasporto merci hanno assunto, già da alcuni anni, un ruolo rilevante nell’area orientale di Napoli, con impatti significativi sulla qualità urbana ed ambientale dell’area. In quest’area, anche grazie alla sua vicinanza ai principali nodi della mobilità (porto, aeroporto, stazione ferroviaria e alla significativa presenza di aree produttive dismesse o in dismissione, trovano oggi spazio numerose attività di stoccaggio e spedizione merci, in molti casi localizzate all’interno di ex aree industriali, in assenza di una reale ottica “sistemica”. Pertanto, a partire da una breve disamina dell’evoluzione dell’area orientale e di quanto previsto dagli strumenti urbanistici vigenti per la sua trasformazione, il contributo focalizza l’attenzione sul ruolo attuale dslle attività di stoccaggio e trasporto merci nell’area. Quindi, sulla base di alcune recenti esperienze di italiane e in riferimento ad ipotesi già avanzate per l’organizzazione di una piattaforma logistica nell’area orientale di Napoli -quale strumento per ottimizzare le necessità di stoccaggio e trasporto merci riducendone le esternalità negative- valuta la compatibilità di tali scelte con le prospettive di evoluzione/trasformazione dell’area e il potenziale ruolo che l’area potrebbe svolgere in una prospettiva di ri-organizzazione del trasporto merci in ambito urbano.

    Tropical storms and severe weathers are listed as one of core events that need improved observations and predictions in World Meteorological Organization and NASA Decadal Survey (DS) documents and have major impacts on public safety and national security. This effort tries to observe surface air pressure, especially over open seas, from space using a Differential-absorption BArometric Radar (DiBAR) operating at the 50-55 gigahertz O2 absorption band. Air pressure is among the most important variables that affect atmospheric dynamics, and currently can only be measured by limited in-situ observations over oceans. Analyses show that with the proposed space radar the errors in instantaneous (averaged) pressure estimates can be as low as approximately 4 millibars (approximately 1 millibar under all weather conditions). With these sea level pressure measurements, the forecasts of severe weathers such as hurricanes will be significantly improved. Since the development of the DiBAR concept about a decade ago, NASA Langley DiBAR research team has made substantial progress in advancing the concept. The feasibility assessment clearly shows the potential of sea surface barometry using existing radar technologies. The team has developed a DiBAR system design, fabricated a Prototype-DiBAR (P-DiBAR) for proof-of-concept, conducted lab, ground and airborne P-DiBAR tests. The flight test results are consistent with the instrumentation goals. Observational system simulation experiments for space DiBAR performance based on the existing DiBAR technology and capability show substantial improvements in tropical storm predictions, not only for the hurricane track and position but also for the hurricane intensity. DiBAR measurements will lead us to an unprecedented level of the prediction and knowledge on global extreme weather and climate conditions.

Ed è proprio il collocarsi all'interno di questa viva esperienza umana che consente di cogliere in modo più diretto la dimensione antropologica che pare emergere dagli scrittori monastici di questo periodo.

    The application of Life Cycle Assessment (LCA) methodology as environmental balance tool is particularly suitable for the study of complex system such as municipal solid waste (MSW) collection, treatment and disposal systems. In this case a detailed analysis is carried out referring to an overall environmental balance based on two different waste treatments: land filling and incineration. The comparison carried out based on the LCA methodology and referring to specific process assumptions allowed to foreground that waste to energy treatments get a net overall balance lower than all the different land filling options, referring also to energy recovery from collected biogas. [Italian] La applicazione di metodologie di bilancio ambientale LCA (Life Cycle Assessment) si adatta particolarmente allo studio disistemi complessi quali quelli di raccolta, trattamento e smaltimento di rifiuti. In questo caso viene affrontata nel dettaglio la valutazione in termini di bilancio complessivo di diverse opzioni di trattamento basate su posa a discarica e trattamento termico. Il confronto effettuato mediante il percorso metodologico seguito, ha permesso di valutare, sulla base delle ipotesi di processi fatte, come il trattamento termico con recupero energetico abbia un bilancio netto ambientale inferiore rispetto a qualsiasi opzione di posa a discarica, anche dotata di recupero energetico dal biogas.

    Di(2-ethylhexyl) phthalate (DEHP) is considered to be an environmental endocrine disruptor at high levels of general exposure. Studies show that DEHP may cause testicular toxicity on human being. In this study, metabonomics techniques were used to identify differential endogenous metabolites, draw the network metabolic pathways, and conduct network analysis, to determine the underlying mechanisms of testicular toxicity induced by DEHP. The results showed that DEHP inhibited synthesis and accelerated β-oxidation of fatty acids and impaired the tricarboxylic acid cycle (TCA cycle) and gluconeogenesis, resulting in lactic acid accumulation and an insufficient ATP supply in the microenvironment of the testis. These alterations led to testicular atrophy and, thus, may be the underlying causes of testicular toxicity. DEHP also inhibited peroxisome proliferator activated receptors in the testis, which may be another potential reason for the testicular atrophy. These findings provided new insights to better understand the mechanisms of testicular toxicity induced by DEHP exposure.

    Full Text Available Leggere autobiografie consente di conoscere esperienze e momenti della vita che restano ignoti a chi non li ha vissuti. Le autobiografie ci svelano un mondo e, nello stesso tempo, ci introducono in esso. Illustrano e spiegano senza illustrare e senza spiegare. Catturano il lettore nella narrazione e, rendendolo protagonista di quello che accade, gli fanno provare le emozioni di chi racconta e gli mostrano la realtà attraverso i suoi occhi. La corrente sociologica dell’Interazionismo simbolico, un approccio che dà particolare rilievo ai significati attribuiti dagli uomini agli oggetti di cui hanno esperienza, considera le storie di vita uno strumento di indagine prezioso. Il racconto di un tratto della vita, o della vita in genere, consente di raggiungere una conoscenza della realtà soggettiva di chi narra molto superiore rispetto a quella ottenuta attraverso questionari o interviste strutturate.

    Full Text Available In order to interpret the links between Venice and Byzantium, it is firstly described how earliest houses in Venice were decorated by using sculptures coming from trading places. It is described the use of disassembled elements and the replacement of others, such as cornices, windows’ elements, coats of arms, among others. These were used firstly as a revival (Neo-Byzantine, 15th century, and later as reflection of the Venetian society «prudence», related to its behaviours and traditions. This prudence is mainly shown in the Renaissance. Besides this, other aspects such as the type of building and the façades, which are the main transformed surface, are analysed with the aim of researching periodical and characteristic dynamics, mainly in those façades showing stylistic renewal and new elements. Some external façades have maintained specific and easy observable characteristics, so they can be associated to a determined stylistic and morphological period. Other façades are stratified, as it is shown by the presence of elements (windows, cornices, … of different building phases. After tracing the main stratifying processes in about 40 study-cases, thanks to a macroscopic analysis, some ways of new composition elements and different stratified units are described. According to this, it is clear that the main principle is the searching for symmetry. Finally, some ways of intervention on the façades are described, highlighting some significant cases.[it] Nella prima parte dell’articolo viene descritto il modo di adornare le prime case veneziane con sculture importate dai luoghi del commercio, come ricostruzione del legame fra Venezia e Bisanzio.

    In the bacterium Escherichia coli, some intermediates of the sulfate assimilation and cysteine biosynthesis pathway can act as signal molecules and modulate gene expression. In addition to sensing and utilization of sulphur sources, these signaling mechanisms also impact more global cell processes, such as resistance to antimicrobial agents and biofilm formation. In a recent work, we have shown that inactivation of the cysH gene, encoding phosphoadenosine-phosphosulfate (PAPS) reductase, and the consequent increase in intracellular PAPS concentration, strongly affect production of several cell surface-associated structures, enhancing surface adhesion and cell aggregation. In order to identify the molecular mechanism relaying intracellular PAPS concentration to regulation of cell surface-associated structures, we looked for mutations able to suppress the effects of cysH inactivation. We found that mutations in the adenylate cyclase-encoding cyaA gene abolished the effects of PAPS accumulation; consistent with this result, cyclic AMP (cAMP)-dependent gene expression appears to be increased in the cysH mutant. Experiments aimed at the direct identification of proteins interacting with either CysC or CysH, i.e. the PAPS-related proteins APS kinase and PAPS reductase, allowed us to identify several regulators, namely, CspC, CspE, HNS and HupA. Protein-protein interaction between HupA and CysH was confirmed by a bacterial two hybrid system, and inactivation of the hupA gene enhanced the effects of the cysH mutation in terms of production of cell surface-associated factors. Our results indicate that PAPS can modulate different regulatory systems, providing evidence that this molecule acts as a global signal molecule in E. coli. Copyright © 2016 Elsevier Ireland Ltd.

  5. Caravaggio e il Maccheronico di Teofilo Folengo

    Directory of Open Access Journals (Sweden)

    Bernardo Piciché

    2013-06-01

    Full Text Available Il presente studio ipotizza un’affinità tra Caravaggio e Teofilo Folengo, argomentando che la pittura del primo presenta analogie estetiche e etiche con la produzione in latino maccheronico del secondo. Il Baldus costituisce un tipico esempio di quella che Genette definirà come «parodia seria»: attraverso il rovesciamento e la irrisione beffarda Folengo ingaggia tenzone contro l’arte paludata e il travisamento dei valori cristiani. Non si tratta qui di stabilire un’influenza di Folengo su Caravaggio, bensì un’analogia, in virtù di un filo di congiunzione ideale, la cui presumibilità viene corroborata anche dal substrato biografico-culturale e da comune spirito religioso. Sia in Folengo che in Caravaggio sono stati individuati i caratteri di un certo modo della cultura lombarda di essere “contro” al punto che il duo Folengo-Caravaggio sembra epitomizzare l’antitesi al decorum curialcortigianesimo di Castiglione e Raffaello. Il Cristo-paradosso costituisce la vera fonte ispiratrice per entrambi. La comparazione tra due arti deve tenere conto dei diversi strumenti espressivi, e questo costituirà uno dei soggetti di riflessione nel testo. Se l’ipotesi della consentaneità viene ragionevolmente difesa, perché non individuare una componente maccheronica anche nell’arte di Caravaggio? Agli storici d’arte, tuttavia, decidere se si possa considerare il maccheronico come categoria pittorica

Non sono stati mai identificati vettori di zoonosi o altri batteri che siano di alcun interesse per la salute umana, mentre si descrivono qui alcune specie nuove per la fauna italiana in relazione ai Chirotteri quali Providencia alcalifaciens in N.noctula, Serratia marcescens in M. schreibersii e Klebsiella oezaenale in R. hipposideros. Il lavoro invita inoltre ad una maggiore collaborazione e a stringere accordi per ampliare la possibile raccolta dei campioni.

  7. Crystal structures of human sulfotransferases SULT1B1 and SULT1C1 complexed with the cofactor product adenosine-3'- 5'-diphosphate (PAP)

    Cytosolic sulfotransferases (SULTs), often referred as Phase II enzymes of chemical defense, are a superfamily of enzymes that catalyze the transfer of a sulfonate group from 3{prime}-phosphoadenosine 5{prime}-phosphosulfate (PAPS) to an acceptor group of substrates. This reaction modulates the activities of a large array of small endogenous and foreign chemicals including drugs, toxic compounds, steroid hormones, and neurotransmitters. In some cases, however, SULTs activate certain food and environmental compounds to mutagenenic and carcinogenic metabolites. Twelve human SULTs have been identified, which are partitioned into three families: SULT1, SULT2 and SULT4. The SULT1 family is further divided in four subfamilies, A, B, C, and E, and comprises eight members (1A1, 1A2, 1A3, 1B1, 1C1, 1C2, 1C3, and 1E1). Despite sequence and structural similarity among the SULTs, the family and subfamily members appear to have different biological function. SULT1 family shows substrate-binding specificity for simple phenols, estradiol, and thyroid hormones, as well as environmental xenobiotics and drugs. Human SULT1B1 is expressed in liver, colon, small intestine, and blood leukocytes, and shows substrate-binding specificity to thyroid hormones and benzylic alcohols. Human SULT1C1 is expressed in the adult stomach, kidney, and thyroid, as well as in fetal kidney and liver. SULT1C1 catalyzes the sulfonation of p-nitrophenol and N-hydroxy-2-acetylaminofluorene in vitro. However, the in vivo function of the enzyme remains unknown. We intend to solve the structures for all of the SULTs for which structural information is not yet available, and compare the structural and functional features of the entire SULT superfamily. Here we report the structures of two members of SULT1 family, SULT1B1 and SULT1C1, both in complex with the product of the PAPS cofactor, adenosine-3{prime}-5{prime}-diphosphate (PAP).

    Measures of health-related quality of life (HRQL) specific for sleep disorders have had limited psychometric evaluation in the context of randomized controlled trials (RCTs). We investigated the psychometric properties of the Functional Outcomes of Sleep Questionnaire (FOSQ) and Sleep Apnea Quality of Life Instrument (SAQLI). We evaluated the FOSQ and SAQLI construct and criterion validity, determined a minimally important difference, and assessed for associations of responsiveness to baseline subject characteristics and continuous positive airway pressure (CPAP) adherence in a RCT population. Secondary analysis of data collected in a multisite RCT of home versus laboratory-based diagnosis and treatment of obstructive sleep apnea (HomePAP trial). Individuals enrolled in the HomePAP trial (n = 335). N/A. The FOSQ and SAQLI subscores demonstrated high reliability and criterion validity, correlating with Medical Outcomes Study 36-Item Short Form Survey domains. Correlations were weaker with the Epworth Sleepiness Scale (ESS). Both the FOSQ and SAQLI scores improved after 3 mo with CPAP therapy. Averaging 4 h or more of CPAP use was associated with an increase in the FOSQ beyond the minimally important difference. Baseline depressive symptoms and sleepiness predicted FOSQ and SAQLI responsiveness; demographic, objective obstructive sleep apnea (OSA) severity and sleep habits were not predictive in linear regression. The FOSQ and SAQLI are responsive to CPAP intervention, with the FOSQ being more sensitive to differences in CPAP adherence than the SAQLI. These instruments provide unique information about health outcomes beyond that provided by changes in physiological measures of OSA severity (apnea-hypopnea index).

Model pendidikan pesantren menjamur jauh sebelum lembaga pendidikan formal didirikan di Indonesia, sehingga kontribusinya sangat besar dalam pembangunan bangsa ini. Mempertahankan eksistensinya di tengah tren perkembangan masyarakat modern tentunya tidak mudah. Karena pesantren, di satu sisi, merupakan lembaga penguatan keagamaan dan moral, tetapi di sisi lain ia harus mampu beradaptasi dan bermetamorfosis sesuai dengan perkembangan masyarakat modern. Tantangan besar dalam masyarakat modern adalah dekadensi moral dan agama, lambatnya laju perkembangan ekonomi masyarakat, dan tingginya angka konsumerisme masyarakat. Berdasarkan tantangan ini, pesantren dapat melakukan revitalisasi peran dan fungsinya sebagai lembaga pendidikan dan pusat pemberdayaan masyarakat.     Abstract: This paper describes the development of the role and function of pesantren starting from the beginning of "its birth"  in traditional society to model of pesantren the advancement of information technology. Pesantren has flourished long before the formal educational institutions established in Indonesia. Thus, it has great contribution to the development of this nation. Maintaining its existency  in the middle of the development trend of modern society is certainly not easy for pesantren. In one side, it is an institution for strengthening of religious and moral issues but on the other hand it must be able to adapt and metamorphose in accordance with the development of modern society. The major challenges in modern society is the moral and religious decadence, the slow pace of economic development, and the high rate of consumerism. For these challenges, pesantren can revitalize its role and function as educational institutions

    Conclusion: Psychosocial burden due to abnormal Pap smear results in terms of mental stress, overwhelming beliefs, and feelings of guilt and worry of HPV infection and possibility of cervical cancer were noted more in reproductive age groups as compared to the menopausal age group. Health-care providers should be aware of these psychosocial effects whereby they can refer such patients to a gynecologic oncologist for proper counseling at the proper time so that the negative impact due to this psychosocial burden can be prevented.

    Standard polymeric materials as well as mixtures of them coming from urban wastes, were milled at near room temperature in suitable milling conditions. All the experiments carried out gave a material having a homogeneous fibrous aspect. Structural and thermal analysis of the resulting material clearly shows that the mechanochemical action is able to promote a deep destructuring of the starting networks with a very high energy storage in the milled materials. Further, the fibrous material can be easily consolidated whatever the starting composition of the mixture. preliminary results, coming from mechanical tests on compacted materials, lead to an optimistic conclusion as far as plastic recycling by ball milling is concerned. [Italian] Materiali polimerici standard, cosi' come miscele di materiali plastici provenienti da rifiuti solidi urbani, sono stati macinati a temperatura pressoche' ambiente in opportune condizioni operative. Tutti gli esperimenti hanno prodotto un materiale morfologicamente omogeneo di aspetto fibroso. Le analisi termiche e strutturali condotte sui prodotti mostrano chiaramente come l'azione meccanochimica sia in grado di promuovere una forte destrutturazione del materiale di partenza, accompagnata da un evidente accumulo di energia nel prodotto macinato. In aggiunta, il materiale fibroso puo' essere facilmente consolidato in forme finite, indipendemente dalla composizione di partenza. I risultati preliminari delle prove meccaniche eseguite sui materiali consolidati inducono a conclusioni ottimistiche relativamente all'utilizzo di tecniche di macinazione ad alta energia per il riciclaggio di materiali plastici.

    2009-05-01

    Full Text Available La necropoli di Sorres si trova nel territorio del Comune di Borutta in provincia di Sassari. E’ ubicata lungo il versante SE del colle di Sorres, sul quale sorge imponente la chiesa in stile romanico di San Pietro di Sorres (XI-XII sec. sede dell’antica diocesi medievale. La necropoli è composta attualmente da cinque tombe a grotticella artificiale del tipo a domus de janas, scavate nella roccia calcara durante il neolitico recente ed in uso per tutto l’eneolitico. Si presume che fosse l’area sepolcrale dell’insediamento in grotta di Ulàri, una cavità carsica di notevoli dimensioni il cui ingresso si apre lungo il versante Nord del colle; la grotta ha restituito testimonianze archeologiche che vanno dal neolitico media fino al medioevo. La necropoli di Sorres, sebbene sia stata rimaneggiata nella forma degli ambienti ipogei e nella destinazione d’uso, costituisce una delle principali testimonianze del capillare tessuto insediativo del territorio del nord Sardegna.

    Full Text Available Lo studio è incentrato sul tentativo di comprendere la scena presente sulla lorica di una statua acefala di probabile fine età claudia rinvenuta nell'area archeologica di Rusellae (Roselle, GR all'interno di un edificio connesso al culto imperiale. La decorazione analizzata è composta da diversi elementi: un trofeo di armi ed un'aquila in posizione pressocchè centrale, ai loro lati si dispongono figure umane interpretabili come barbari e per le quali si propone l'identificazione con il britanno Caratacus accompagnato dai suoi familiari mentre rivolge una supplica di liberazione al Senato ed all'imperatore Claudio, secondo l'episodio riportato negli Annales di Tacito (12.33-40.

  7. Analisi dell’utilizzo di Twitter nella costruzione di un seminario sperimentale

    Directory of Open Access Journals (Sweden)

    Wolfgang Reinhardt

    2013-03-01

    Full Text Available Nonostante i massicci cambiamenti sociali e tecnologici che si sono verificati a causa del Web negli ultimi anni, i corsi universitari spesso enfatizzano metodi di insegnamento da tempo consolidati e basati su strumenti di apprendimento e risorse tradizionali. Durante tali corsi gli studenti spesso acquisiscono una conoscenza che non è aggiornata e che è lontana da un apprendimento realistico, basato su problemi. L'uso di strumenti e metodi più recenti spesso rimane fuori dalla padronanza degli studenti. In questo contributo si descrive brevemente l’impostazione sperimentale di un seminario in due università tedesche dove l’uso di Social Media per la comunicazione e la collaborazione è stato saldamente integrato alla progettazione di un percorso di apprendimento formale. Si illustra, inoltre, l'utilizzo di Twitter durante il seminario, usando metodologie riprese dalla Social Network Analysis.

  8. Macchine per giuoco nella proposta di Leopardi

    Directory of Open Access Journals (Sweden)

    Laura Neri

    2017-06-01

    Full Text Available Un’operetta morale di Leopardi, la Proposta di premi fatta dall’Accademia dei Sillografi, adotta il linguaggio tecnico di un bando di concorso per proporre tre premi agli inventori di tre macchine umane perfette: l’amicizia, la magnanimità, la fedeltà coniugale sono gli obiettivi delle invenzioni scientifiche. Il tono serio cela in realtà la  polemica contro l’antropocentrismo e soprattutto contro l’ottimismo del suo tempo.  One of Leopardi’s Operette morali, Proposta di premi fatta dall’Accademia dei Sillografi, adopts the gergon of a competition notice to propose three prizes to the inventors of three perfect human machines: friendship, magnanimity, conjugal fidelity are the aims of scientific inventions. The serious tone really conceals the controversy against anthropocentrism and above all against the optimism of its time.

  9. Analisi dell'efficacia di un programma di prevenzione secondaria del carcinoma orale

    Full Text Available

    In Italia i carcinomi del cavo orale (KCO sono diagnosticati
    prevalentemente al II-IV stadio TNM con conseguenti basse sopravvivenza a 5 anni e qualità della vita. Una maggior frequenza di diagnosi allo stadio I porterebbe a migliorare ampiamente i valori medi dei suddetti parametri.
    Scopo del presente lavoro è stato valutare l’efficacia di un programma di prevenzione secondaria del KCO in termini di aumento di diagnosi allo stadio I e di vite salvate.

    Abbiamo stimato la prevalenza di casi istopatologicamente
    accertati (livello C3 di leucoplachia, principale lesione precancerosa del KCO, nella ASL/RMA come prodotto tra la prevalenza stimata di leucoplachia diagnosticata clinicamente (livello C2 (2989,2Ĩ13077,7 e la proporzione, scelta arbitrariamente, di C3 tra i C2 (0,50.

    Tenendo presente che nel campione studiato nella ASL/RMA la proporzione di KCO allo stadio I tra i C3 era 0,03, abbiamo stimato il numero di KCO.

    Abbiamo stimato quanti KCO verrebbero diagnosticati allo stadio I se venisse attuato un programma di prevenzione secondaria, considerando diversi livelli di compliance, e sulla base di una sopravvivenza media a 5 anni, in Italia, del 53% per tutti gli stadi e del 79% per i KCO allo stadio I, abbiamo calcolato il numero di vite salvate. I valori sono stati espressi come IC95.

    Le prevalenze di leucoplachia C3 e KCO sono risultate,
    rispettivamente, 1494,6Ĩ6538,8 e 44,8Ĩ196,2. Con compliance del 10%, 40% e 75% verrebbero diagnosticati, rispettivamente, 4,5Ĩ19,6, 17,9Ĩ78,5 e 33,6Ĩ147,2 casi di KCO e le vite salvate sarebbero 1,1Ĩ5,1, 4,6Ĩ20,4 e 8,7Ĩ38,3 rispettivamente.
    In termini di vite salvate i dati evidenziano la necessita di attuare programmi di screening del KCO, anche nell' eventualità di uno scarso coinvolgimento della popolazione a rischio.

    2014-10-01

    Full Text Available Il saggio indaga due diverse strategie di diserzione rappresentate in due romanzi di guerra: I parenti del sud di Carlo Montella e Going After Cacciato di Tim O’Brien. Nelle due opere analizzate la diserzione sembra essere collegata al conflitto che fa da sfondo al romanzo. Nel libro di Montella,il protagonista, ancora obnubilato dalle dottrine tautologiche fasciste, qualche settimana dopo l’armistizio di Cassibile decide di disertare e di fuggire nella villa di un’anziana parente, con lo scopo di rinsavire dall’ideologia del regime. Nel romanzo di O’Brien, invece, la fuga messa in scena dall’autore sembra avere gli stessi tratti grotteschi e assurdi del conflitto in cui è stato catapultato il protagonista,la Guerra del Vietnam.

    2003-10-01

    Full Text Available Con le sue 11 specie e le oltre 6000 presenze di Chirotteri la Riserva naturale orientata di Onferno è certamente un punto di notevole interesse nel patrimonio naturale italiano. A seguito dei piani di indagine e di sorveglianza posti in essere fin dalla sua creazione nel 1992 da parte della gestione della Riserva e soprattutto grazie al progetto LIFE in corso, si riassumono qui i principali tratti fenologci delle diverse specie nella cavità. Il sistema ipogeo è altamente differenziato topografica e in termini di microclima, come rilevato dal sistema di monitoraggio presente. Da Dicembre inizia il periodo più tipicamente invernale con rapido abbandono della cavità principale da parte dei miniotteri. Vi rimangono poche decine di esemplari e altrettanti rinolofidi delle diverse specie. Tale situazione si prolunga con alcune piccole variazioni fino a Marzo. Al cambio di stagione i miniotteri si muovono dai rifugi posti soprattutto in un tunnel a S. Marino (circa 11 km in linea d?aria a temperatura tra i 3 e 5 °C per tornare nel tratto principale a circa 7°C. I rinolofidi mantengono le posizioni e i numeri precedenti. Con Aprile il gruppo dei miniotteri, oramai completo o quasi, si sposta nella Sala Guano o rimane in vari ambiti del percorso principale. I rinolofidi appaiono in movimento ma il loro numero diminuisce almeno dalle zone di controllo. A Maggio compaiono anche i grandi vespertili già aggregati al grande gruppo dei miniotteri che spesso si presenta in contingenti suddivisi in vari ambiti della grotta. Non si ritrovano più rinolofi maggiori, mentre euryale e minore raggiungono le sale più calde e secche. Con Giugno i contingenti si concentrano nella grande sala ?Quarina? per formare nella seconda metà la colonia riproduttiva. Dal 15 circa iniziano i parti in tutte le specie. Nel Miniottero si registrano scarti di almeno una settimana tra l?avvio della riproduzione e le ultime nascite. Tutto Luglio è speso nella crescita dei

    Full Text Available Nelle conversazioni quotidiane e in rete si discute molto della dipendenza da serie televisive, con particolare riferimento alle serie continue di ultima generazione (tra cui Game of Thrones, Homeland, House of Cards e simili, le quali sembrano incoraggiare il cosiddetto binge-watching più di qualsiasi altra fiction precedente. Molti commentatori paragonano questo fenomeno alla tossicodipendenza, e una recente ricerca psicologica (Hoon Hi Sung, Eun Yeon Kang, Wei-Na Lee 2015 collega la dipendenza da serie alla depressione.
