    BACKGROUND: The psychometric validity of many subscales of the 90-item Hopkins Symptom Checklist (SCL-90) remains largely unknown. Therefore, the aim of the present study was to evaluate the psychometric properties of the "Hamilton-subscales" for depression (SCL-D16), anxiety (SCL-A14), their 6......-item core-measures (SCL-D6 and SCL-A6), the anxiety symptom scale (SCL-ASS8) and the interpersonal sensitivity scale (IPS5). METHODS: The psychometric properties of the SCL-D16, SCL-A14, SCL-D6, SCL-A6, SCL-ASS8, and the IPS5 were evaluated based on SCL-90 ratings from 850 day patients from a Danish...... SCL-90 subscales were identified. Using these scales it is possible to perform a psychometrically valid evaluation of psychiatric patients regarding the severity of depression (HAM-D6), specific anxiety (SCL-ASS8) and interpersonal sensitivity (IPS5)....

    Full Text Available Objectives This study was conducted to investigate the relationships among job stress, job satisfaction, and mental health in marine officers. Methods The researchers gathered data on marine officers working at a harbor in Chungcheong Province, South Korea, using a self-reported questionnaire. Mental health was measured by the Symptom Checklist-90-Revision (SCL-90-R, and general characteristics including socioeconomic factors, job stress, and job satisfaction were measured by structured questionnaires. Multiple regression analysis was performed to investigate the relationships among job stress, job satisfaction, and mental health status according to the symptom dimensions of the SCL-90-R. Results Among the marine officers, obsessive-compulsive behavior, depression, and somatization were the most problematic symptoms. Those who reported poor health, low job satisfaction, and high job stress had a higher prevalence of psychoticism, somatization, depression, anxiety, and phobic anxiety. Conclusions An occupational health system should be introduced that would regularly check the mental health of marine officers in charge of ships and sailors, in order to help reduce their stress levels, enhance their job satisfaction, and thereby improve their mental health.

    The Symptom Check-List-90 (SCL-90) is a widely used psychiatric questionnaire which has not yet been validated in Finland. We investigated the utility of the translated version of the SCL-90 in the Finnish population, and set community norms for it. The internal consistency of the original subscales was checked and found to be good. Discriminant function analysis, based on the nine original subscales, showed that the power of the SCL-90 to discriminate between patients and the community is good. Factor analysis of the items of the questionnaire yielded a very strong unrotated first factor, suggesting that a general factor may be present. This together with the fact that high intercorrelations were found between the nine original subscales suggests that the instrument is not multidimensional. The SCL-90 may be useful in a research setting as an instrument for measuring the change in symptomatic distress, or as a screening instrument. The American community norms should be used with caution, as the Finnish community sample scored consistently higher on all subscales.

    The aim of the study was to investigate the relationships between the Symptom Checklist-90-Revision (SCL-90-R) and the Minnesota Multiphasic Personality Inventory (MMPI) in temporomandibular disorders (TMD) patients with psychological problems. Subjective symptoms, objective signs, and psychological characteristics of 36 TMD patients with psychological problems were analyzed. The symptom severity index (SSI) and craniomandibular index (CMI) were used to assess subjective symptoms and objective signs of patients with TMD, respectively. The SCL-90-R and MMPI were used for psychological evaluation. The SSI was not significantly correlated with the CMI in TMD patients with psychological problems, and these indices displayed significant correlations with the SCL-90-R and MMPI in several selected subscales. The results of SCL-90-R had a limited relationship with those of MMPI in these patients. Based on the MMPI diagnosis, the SCL-90-R somatization subscale showed moderate to high sensitivity and specificity, but the SCL-90-R depression subscale showed moderate to low sensitivity and specificity. Considering the limited relationship between the SCL-90-R and MMPI in TMD patients with psychological problems, more comprehensive psychological tests are recommended when clinicians suspect patients with TMD of having accompanying psychological problems. © 2011 John Wiley & Sons A/S.

    Full Text Available Multidimensional Inventory Check List of Symptoms (SCL-90-r is based on self-evaluation and it has been used for determination of level of: somatisation, obsessive-compulsive symptoms, interpersonal sensitivity, depression, anxiety, hostility, phobias, paranoia and psychosis at persons which are exposed to long term emotional and physical stress. Our goal was to determine relations of physical trauma and psychological changes at persons with lower extremities amputations and to determine factors which influence those changes. Thirty seven persons with lower extremities amputations were examined. The sample included 26 (70.2 % veterans and 11 (29.7 % civilians with diseases related amputations. They voluntarily filled Check List of Symptoms SCL-90-r. Symptoms Inventory includes 9 dimensions of primary symptoms: SCL1-somatisation, SCL2-obsessive-compulsive symptoms, SCL3-interpersonal sensitivity, SCL4-depression, SCL5-anxiety, SCL6-hostility, SCL7-phobias, SCL8-paranoia, SCL9-psychosis and SCL10-extra scale. Inventory includes 90 statements, each evaluated with five-level scale of disorder. Every answer is graded with 0-4 points. Thirty seven persons with lower extremities amputations and average chronological age 46.2 +/- 10.92 years were analyzed. Considering marital status 30 (81.1 % of them were married, 4 (10.8 % were not married and 3 (8.1 % were widowers. Considering level of amputation 27 of them (73.0 % had amputation below knee, 5 (13.5 % of them amputation above knee and 5 of them (13.5 % foot amputation. SCL-90-r in both groups determined high level of sensitivity, anxiety, hostility and paranoia. Veterans showed higher level of paranoia comparing to civilians (p<0.002, and younger veterans and married ones had higher level of paranoia comparing to other veterans (p<0.01. Persons with amputations below and above knee showed higher level of paranoia comparing those with foot amputation (p<0.001. Persons with lower extremities

    The aim of the study was to compare the screening properties of two General Health Questionnaire (GHQ) versions and the Symptom Checklist (SCL-90), and to evaluate them as psychiatric screening instruments in Finland. We administered the GHQ-36 and the SCL-90 to psychiatric outpatients (n=207) and to a community sample (n=315). Receiver operating characteristic (ROC) analysis was used to estimate the screening performance of the two instruments and of the GHQ-12 extracted from the GHQ-36. The screening properties of the scales were found to be good and similar. Suggested optimal cut-off points were 3/4 for the GHQ-12, 8/9 for the GHQ-36 and 0.90/0.91 for the SCL-90. In conclusion, the scales functioned equally well in screening. This favors the GHQ-12 for pure screening. When information on the symptom level is also needed, the GHQ-36 and the SCL-90 become better choices. The cut-off points presented here should be considered in the future Finnish psychiatric screening studies.

    Full Text Available "nObjective: Inconsistent results have been reported regarding the symptom dimensions relevant to psychosis in symptoms check list revised (SCL90-R, i.e., "psychoticism" and "paranoid ideation". Therefore, some studies have suggested different factor structures for questions of these two dimensions, and proposed two newly defined dimensions of "schizotypal signs" and "schizophrenia nuclear symptoms". We conducted an exploratory factor analysis on the items of these two dimensions in a general population sample in Iran. "nMethod: A total of 2158 subjects residing in Southern Tehran (capital of Iran were interviewed using the psychoticism and paranoid ideation questions in SCL90-R to assess severity of these symptom dimensions. Factor analysis was done through SAS 9.1.3 PROC FACTOR using Promax rotation (power=3 on the matrix of "polychoric correlations among variables" as the input data. "nResults: Two factors were retained by the proportion criterion. Considering loadings >= 0.5 as minimum criteria for factor loadings, 7 out of 10 questions  from psychoticism ,and 3 out of 6 questions from paranoid ideation were retained, and others were eliminated. The factor labels proposed by the questionnaire suited the extracted factors and were retained. Internal consistency for each of the dimensions was acceptable (Cronbach's alpha 0.7 and 0.74 for paranoid ideation and psychoticism respectively. Composite scores showed a half-normal distribution for both dimensions which is predictable for instruments that detect psychotic symptoms. "nConclusion: Results were in contrast with similar studies, and questioned them by suggesting a different factor structure obtained from a statistically large population. The population in a developing nation (Iran in this study and the socio-cultural differences in developed settings are the potential sources for discrepancies between this analysis and previous reports.

    To explore the effect of application of the measurement table of PHI and 16PF and SCL-90 for freshmen psychology inspection. The measurement tables of PHI and 16PF for psychology inspection of freshmen of 2004-2007 years were used to sift crisis intervention objects. Continuous four years test showed certain stability, in addition to excited factors,the scores of Freshmen's PHI factors were more lower than normal. The incidence rates of mental problems screened by PHI table were very low and 3-5 serious-mental-problem students weren't detected. The problem can be resolved by the application of PHI combined with 16PF through remesuring the suspected cases by SCL-90. The combinative application of PHI, 16PF and SCL-90 would be better.

    Addiction is a relapsing chronic condition in which psychiatric phenomena play a crucial role. Psychopathological symptoms in patients with heroin addiction are generally considered to be part of the drug addict's personality, or else to be related to the presence of psychiatric comorbidity, raising doubts about whether patients with long-term abuse of opioids actually possess specific psychopathological dimensions. Using the Self-Report Symptom Inventory (SCL-90), we studied the psychopathological dimensions of 1,055 patients with heroin addiction (884 males and 171 females) aged between 16 and 59 years at the beginning of treatment, and their relationship to age, sex and duration of dependence. A total of 150 (14.2%) patients with heroin addiction showed depressive symptomatology characterised by feelings of worthlessness and being trapped or caught; 257 (24.4%) had somatisation symptoms, 205 (19.4%) interpersonal sensitivity and psychotic symptoms, 235 (22.3%) panic symptomatology, 208 (19.7%) violence and self-aggression. These dimensions were not correlated with sex or duration of dependence. Younger patients with heroin addiction were characterised by higher scores for violence-suicide, sensitivity and panic anxiety symptomatology. Older patients with heroin addiction showed higher scores for somatisation and worthlessness-being trapped symptomatology. This study supports the hypothesis that mood, anxiety and impulse-control dysregulation are the core of the clinical phenomenology of addiction and should be incorporated into its nosology.

    Personality disorders are associated with dysfunction in a variety of areas. Recent longitudinal research has shown that personality disorders are also predictive of problems later in life, as well as of poor response to treatment of depression and anxiety. This study assessed whether personality disorder features were associated with psychiatric symptoms in a cohort of women treated for substance abuse in Sweden. Patients were diagnosed with personality disorders using the Structured Clinical Interview for DSM-IV (SCID-II) personality questionnaire and SCID-II interview, and were then administered a self-report questionnaire designed to measure symptoms of psychiatric illness, the Symptoms Checklist-90 (SCL-90), during and five years after treatment. Concurrently, features of all personality disorders, except histrionic, were associated with SCL-90 score. At five-year follow-up, most personality disorders remained associated with SCL-90 score, with the exception of paranoid and schizoid personality disorder. After controlling for baseline score on the SCL-90, conduct disorder, borderline personality disorder, and narcissistic personality disorder remained significantly associated with symptoms at follow-up. After controlling for abstinence and baseline score, only borderline personality disorder features remained associated with SCL-90 score at follow-up. Patients with personality disorders should be monitored after treatment for psychiatric symptoms.

    The ability of the Young Adult Self-Report (YASR), the Symptom Checklist (SCL-90) and the General Health Questionnaire (GHQ-28) to predict maladjustment across a 2-year time-span was assessed in a general population sample of 528 18- to 22-year-olds. Referral for mental health services and need for professional help were predicted by total problem scores of the YASR, the GHQ-28 and the SCL-90 and by the internalizing scale of the YASR. Furthermore, the internalizing scale predicted suicide attempts or suicidal ideation, whereas the externalizing scale predicted police contacts. The YASR delinquent behavior syndrome was the only significant predictor of alcohol abuse. The findings supported the validity of the YASR as an instrument for the assessment of psychopathology in young adults.

    Full Text Available Con base en una muestra probabilística de 466 estudiantes universitarios mexicanos, se explora la relación entre distrés psicológico y conductas de riesgo (consumo de sustancias, conductas sexuales, y ambas, en hombres y mujeres. Los resultados indican que el distrés psicológico presenta diferencias con mayor frecuencia en el caso de las mujeres que presentan consumo de drogas, tabaco y alcohol, o conductas que mezclan sexo y alcohol, y sexo y consumo de drogas, que en el caso de los hombres. Los hombres con actividad sexual ocasional presentan mayor distrés que quellos que no presentan esta conducta. Como punto de partida, se explora la estructura factorial del SCL-90-R, coincidiendo en los resultados con los obtenidos por investigadores de otras latitudes; al parecer, el análisis factorial no soporta la estructura propuesta por los autores del instrumento.

    The aim of this study was to compare the symptomatic and clinical features of depression among five groups of patients with major depressive disorder (MDD) living in China, Korea, Malaysia/Singapore, Taiwan, and Thailand. Consecutive consenting adults (aged 18-65) who met DSM-IV criteria for non-psychotic MDD – based on the Mini International Neuropsychiatric Interview – and who were free of psychotropic medication were evaluated in a cross-sectional study. Depressive symptoms were evaluated using the 10-item Montgomery–Asberg Depression Rating Scale (MADRS) and the 13-item depression subscale of the Symptoms Checklist 90-Revised (SCL-90-R). In addition, the 10-item SCL-90-R Anxiety Subscale was completed. ancova were conducted, adjusting for confounders: age, completion of secondary education, marital status, work status, religion, index episode duration, and depressive severity. For the magnitude of differences, a threshold of 0.10 was taken as the minimum effect size representing clinical significance, and an effect size of 0.25 was considered moderate. Four MADRS symptoms differentiated these five groups, the most prominent being ‘lassitude’ and ‘inner tension’. Nine SCL-90-R depression items also differentiated the groups, as did eight SCL-90-R Anxiety Subscale items. The MADRS lassitude item had the largest effect size (0.131). The rest of those statistically significant differences did not exceed 0.10. MDD is more similar than different among outpatients in these diverse Asian countries. The between-country differences, while present and not due to chance, are small enough to enable the use of common clinician and self-report rating scales in studies involving Asians with MDD from various ethnic backgrounds.

    Abstract This study investigated the mental health of military transport personnel in the Western Sichuan Plateau of China, and factors that correlate with their mental health. The Symptom Checklist 90 (SCL-90) was used to investigate the mental health status of the subjects. Their scores were compared with the national and military norm in China. Demographic factors were analyzed for associations with SCL-90 scores. Psychological problems were detected in 28.90% of total 1076 male officers and soldiers surveyed. The SCL-90 scale somatization score of these servicemen was higher than the national and military norms in China, while other scores were comparable. The reported physical health symptoms and being an only child were strongly associated with the SCL-90 scores. The mental health of military transport personnel in the China Western Sichuan Plateau should receive more attention. PMID:29561449

    1999-11-01

    To examine the relation between psychiatric symptoms and defense mechanisms, we administered two questionnaires, the Symptom Check-list 90 (SCL-90) and the Defense Style Questionnaire (DSQ) to 122 psychiatric out-patients and to a community sample of 337 subjects. Using regression analysis, we found that 51.8% of the variation in subject's Global Severity Index value could be explained by his defense style. Of the three defense styles, the immature style explained most of the variation in the symptoms. We found little overall evidence for specific connections between particular defenses and symptoms. Projection and dissociation were central in most of the symptom dimensions. We compared patients and controls with the same level of general symptom severity and found that patients used significantly more devaluation and splitting, and controls used significantly more altruism and idealization. Whether defenses predispose to certain symptomatology or are one of its aspects is discussed.

    Anxiety is one of the most common reactions that parents show while understanding their children's intellectual disability due to Down syndrome. Anxiety leads parents not to develop appropriate relations with their children, subsequently their psychological health are at risk. The present study was aimed to determine the effect of problem-focused coping strategy training on psychological symptoms of mothers with Down child. This was an experimental study with pretest and posttest design with case and control group. Sixty-four mothers were selected randomly from Iranian Down Syndrome Charity Society. They completed Symptoms Checklist-90-Revised (SCL-90-R). They were assigned to experimental and control groups in equal. Experimental group participated in 12 training sessions (once a week; 60 minutes for each session) and received problem-focused coping strategy program, but control group did not. After 12(th) session, all subjects completed SCL-90-R again. Analysis of covariance was used for analyzing the data. There was a significant difference (Pstrategy-training program led to improve family's perception towards the child and subsequently promote of mental health of mothers with Down children.

    This study explores the psychological wellbeing of twenty-two (n = 22) adults with achondroplasia. The sample was composed of seven (n = 7) males and fifteen (n = 15) females between the ages of 21 and 75 (mean age = 39.6). Each individual completed four self-administered questionnaires: the Beck Depression Inventory (BDI-l), the Beck Anxiety Inventory (BAI), the Beck Hopelessness Scale (BHS), and Derogatis Symptom Check-list-90-Revisited (SCL-90-R). They also filled out a socio-demographic questionnaire. We found that 31.8% of the sample reported at least one comorbid condition such as, hypertension, diabetes, rheumatoid arthritis, asthma, scoliosis, thyroid problems, neuropathy, psoriasis, gastritis and/or sleep apnea; 32% reported mild to severe depressive symp- toms; 55% reported mild to severe symptoms associated to anxiety and 18% reported mild to severe symptoms associated with hopelessness; 22.7% reported mild to severe symptoms in at least one of the sub-scales in Derogatis Symptom Checklist-90-Revisited (SCL-90-R) particularly the obsessive-compulsive, paranoid and depressive subscales. Chi Square correlations (X2) were made to observe if there was interdependence between the socio-demographic variables and the administered tests. In general, no significant correlations were found between BDI-Il, BAI, BHS, SCL-90-R and civil status, gender, income and age. However, a significant correlation was found between age and the somatization sub-scale of the SCL-90-R (rs = 0.510, p achondroplasia. The development of preventive and cultural sensitive interventions is suggested in order to protect and treat individuals with the condition.

    The aim of the current study was to evaluate the prevalence of psychopathological symptoms in patients who self-reported different forms of bruxism by means of clinical and anamnestic diagnostic criteria. Eighty-five participants were divided into four groups as sleep bruxers (12), awake bruxers (24), sleep-awake bruxers (33), and non-bruxers (16). A self-report symptom inventory questionnaire (Symptom Checklist-90-Revised (SCL-90-R)) was filled out by all groups to determine their psychopathological symptoms. As regards mean psychopathological scores, patients with sleep-awake bruxism endorsed the highest scores. In addition, patients with awake bruxism showed higher scores than patients with sleep bruxism and non-bruxism in most SCL-90-R subscales. Kruskal-Wallis test revealed significant differences between groups in any of the SCL-90-R subscales, except for the psychoticism subscale. Mann-Whitney test followed by Bonferroni's test correction between non-bruxer and sleep-awake bruxer groups revealed significant differences in depression, anxiety, hostility, phobic anxiety, paranoid ideation, global severity index, positive symptom distress index, and positive symptom total in all SCL-90-R subscales. Statistical analysis of our study showed that differences between groups were significant in all SCL-90-R subscales except for the psychoticism subscale. Better distinction of bruxism forms may help to develop new treatment strategies for bruxism disorder.

    Despite the fact that research has demonstrated consistent associations between self-rated measures of personality dimensions and mental disorders, little has been undertaken to investigate the relation between psychiatric symptoms and response patterns to self-rated tests. The aim of this study was to investigate the association between psychiatric symptoms and response quality using indices from our functional method. A sample of 1,784 participants from a Swiss population-based cohort completed a personality inventory (NEO-FFI) and a symptom checklist of 90 items (SCL-90-R). Different indices of response quality were calculated based on the responses given to the NEO-FFI. Associations among the responses to indices of response quality, sociodemographic characteristics and the SCL-90-R dimensions were then established. Psychiatric symptoms were associated with several important differences in response quality, questioning subjects' ability to provide valid information using self-rated instruments. As suggested by authors, psychiatric symptoms seem associated with differences in personality scores. Nonetheless, our study shows that symptoms are also related to differences in terms of response patterns as sources of differences in personality scores. This could constitute a bias for clinical assessment. Future studies could still determine whether certain subpopulations of subjects are more unable to provide valid information to self-rated questionnaires than others.

    Objective: To investigate the occurrence ruleof common psychological abnormalities in petrochemical workers using association rule. Methods: From July to September,2014,the Symptom Checklist-90 (SCL-90)was used for the general survey of mental healthamong all employees in a petrochemical enterprise.The association rule Apriori algorithm was used to analyze the data of SCL-90 and investigate the occurrence rule of psychological abnormalities in petrochemical workers with different sexes,ages,or nationalities. Results: A total of 8 248 usable questionnaires were collected. The SCL-90 analysis showed that 1623 petrochemical workers(19.68%) had positive results,among whom 567(34.94%)had one positive factor and 1056 (65.06%)had two or more positive factors. A total of 7 strong association rules were identified and all of them included obsessive-compulsive symptom and depression. Male({obsessive-compulsive symptom,anxiety}=>{depression}) and female workers ({somatization,depression}=>{obsessive-compulsive symptom}) had their own special association rules. The workers aged 35-44 years had 17 special association rules,and ethnic minorities had 5 special association rules. Conclusion: Employeesin the petrochemical enterprise have multiple positive factors in SCL-90, and employees aged 35-44 years and ethnic minorities have a rich combination of psychological symptoms and need special attention during mental health intervention.

    The purpose of this study is two-fold: (a) to analyze self-concept, self-esteem, and psychopathological symptoms in individuals with and without intellectual disability; and (b) to explore whether there were gender differences in these same variables in both groups. The sample is made up of 170 participants aged 19 to 40, 128 without disability and 42 with intellectual disability. The methodology is descriptive. To measure the variables, three assessment instruments were applied: the "Listado de adjetivos para la evaluaci6n del autoconcepto en adolescentes y adultos" (LAEA; Garaigordobil, in press), the Rosenberg Self-Esteem Scale (RSE; Rosenberg, 1965), and the Revised Symptom Checklist-90 (SCL-90; Derogatis, 1983). The ANOVA showed that participants with intellectual disability scored significantly lower in self-concept and self-esteem, and higher in all the psychopathological symptoms except for somatization. The ANOVA did not reveal significant gender differences in any variables in either of the two groups.

    Both emotional distress (ED) and social isolation/alienation (SI/A) have been found to prospectively predict adverse cardiac events, but few studies have tested the confounding/redundancy of these measures as correlates/predictors of outcomes. In this study, 163 patients with documented coronary artery disease (CAD) were interviewed for multiple indices of SI/A and administered the Symptom Checklist 90 - Revised (SCL90R). A spouse or friend provided an independent rating of ED using the spouse/friend version of the Ketterer Stress Symptom Frequency Checklist (KSSFC). The measures of ED and SI/A covaried. All three scales from the KSSFC (depression, anxiety, and "AIAI" - aggravation, irritation, anger, and impatience), and three scales from the SCL90R (anxiety, depression, and psychoticism), were associated with early Age at Initial Diagnosis (AAID) of CAD. Neither three scales derived from the SCL90R (shyness, feeling abused, and feeling lonely) nor the interview indices of SI/A (married, living alone, having a confidant, self description as a lone wolf, and self-description as lonely) were associated with early AAID. Thus, it is concluded that the present results indicate that ED and SI/A are confounded and that, even when tested head-to-head in a multivariate analysis, only ED is associated with AAID.

    To investigate the psychological characteristics of patients with allergic rhinitis (AR) and its associated factors. Three hundred and seventy-seven patients with AR were evaluated by the Symptom Checklist-90 (SCL-90). The results were compared with a standard, obtained from healthy Chinese population, including factors of gender, age, educational level, medical history of AR, presence of complications, type of allergenic sensitizations and nasal symptoms (using logistic regression analysis). An abnormal psychological state was found in 10% of AR patients, 13% with deuto-healthy, and remaining 77% of AR patients were completely healthy. The SCL-90 scores of the 377 patients were significantly higher than those of the normal standard population, including symptoms of somatization, compulsion, anxiety, rivalry and psychosis (t equals 7.128, 3.943, 2.777, 6.423, 7.507, respectively, all P horror were respectively different in different AR case history (F equals respectively 2.379, 2.255, all P types, educational level, allergen types (all P > 0.05). Snuffle, sneeze and snivel had no influence on patient's SCL-90 scores (all P > 0.05). Itchy nose was a major symptom that affect on AR patients' SCL-90 scores of depression (standard regression b = 0.126, t = 2.076, P < 0.05). AR patients' psychological status was worse than that of the healthy adults.

    2016-01-01

    The Symptom Checklist - Post-Traumatic Stress Disorder Scale (SCL-PTSD), also known as Crime-Related PTSD Scale has been validated in survivors of interpersonal trauma in the general population. However, the psychometric properties have not been investigated in a clinical setting for patients with PTSD from diverse traumatic events. This study investigates the reliability and validity of the Korean version of the SCL-PTSD among 104 psychiatric outpatients with PTSD, caused by interpersonal (n = 50) or non-interpersonal trauma (n = 54). Self-report data of the SCL-PTSD, Beck Depression Inventory (BDI), State-Trait Anxiety Inventory (STAI), and Impact of Events Scale-Revised (IES-R) were gathered. The Korean version of the SCL-PTSD showed excellent internal consistency and moderate-to-good four-week temporal stability in both the interpersonal and non-interpersonal trauma groups. In comparison with other diagnostic groups, the scores of the SCL-PTSD were significantly higher compared to those of adjustment disorder, depression, other anxiety disorders, and schizophrenia, demonstrating its criteria-related validity. Convergent validity was confirmed because the scores of the SCL-PTSD were significantly correlated with BDI, SAI and TAI scores. Concurrent validity was demonstrated by significant correlation with the IES-R score. This study demonstrated the favorable psychometric prosperities of the Korean version of the SCL-PTSD, supporting its use in clinical research and practice. PMID:27134501

    The purpose of this study was to examine the stress responses of parents to the sexual and ritualistic abuse of their children in day-care centers. Sixty-five mothers and 46 fathers of children sexually abused in day-care centers completed the Symptom Checklist-90-Revised (SCL-90-R), a measure of psychological distress. These scores were compared with a carefully matched comparison group of parents of 67 nonabused children. Parents of abused children also completed the Impact of Event Scale (IES), a measure which indexes symptoms that characterize posttraumatic stress disorder. Parents of sexually abused children reported significantly more psychological distress than parents of nonabused children, with parents of ritually abused children displaying the most severe psychological distress. Parents of abused children reported symptom profiles on the SCL-90-R and IES consistent with posttraumatic stress disorder.

    HIV-infected individuals (HIV+) has 2-3 times the rate of tobacco smoking than the general population, and whether smoking may lead to greater psychiatric symptoms or cognitive deficits remains unclear. We evaluated the independent and combined effects of being HIV+ and chronic tobacco-smoking on impulsivity, psychopathological symptoms and cognition. 104 participants [27 seronegative (SN)-non-Smokers, 26 SN-Smokers, 29 HIV+ non-Smokers, 22 HIV+ Smokers] were assessed for psychopathology symptoms (Symptom Checklist-90, SCL-90), depressive symptoms (Center for Epidemiologic Studies-Depression Scale, CES-D), impulsivity (Barratt Impulsiveness Scale, BIS), decision-making (The Iowa Gambling Task, IGT, and Wisconsin Card Sorting Test, WCST), and cognition (seven neurocognitive domains). Both HIV+ and Smoker groups had higher SCL-90 and CES-D scores, with highest scores in HIV+ Smokers. On BIS, both HIV+ and Smokers had higher Total Impulsiveness scores, with higher behavioral impulsivity in Smokers, highest in HIV+ Smokers. Furthermore, across the four groups, HIV+ Smokers lost most money and made fewest advantageous choices on the IGT, and had highest percent errors on WCST. Lastly, HIV+ had lower z-scores on all cognitive domains, with the lowest scores in HIV+ Smokers. These findings suggest that HIV-infection and chronic tobacco smoking may lead to additive deleterious effects on impulsivity, psychopathological (especially depressive) symptoms and cognitive dysfunction. Although greater impulsivity may be premorbid in HIV+ and Smokers, the lack of benefits of nicotine in chronic Smokers on attention and psychopathology, especially those with HIV-infection, may be due to the negative effects of chronic smoking on dopaminergic and cardio-neurovascular systems. Tobacco smoking may contribute to psychopathology and neurocognitive disorders in HIV+ individuals.

    To study perinatal anxiety symptoms in a sample of Mexican mothers. A) To evaluate the effect of certain psychosocial factors during pregnancy on anxiety symptoms at two postpartum time intervals; and B) to determine whether this symptomatology is related to symptoms of postnatal depression. In this secondary data analysis, 156 women were interviewed during pregnancy (T1): 149 were interviewed again at 6 weeks postpartum (T2) and 156 at 4-6 months postpartum (T3). Subjects were selected from women seeking prenatal attention at three health centers in Mexico City who presented with depressive symptomatology and/or previous history of depression. Two models were subjected to multivariate regression analysis to determine the influence of psychosocial factors in pregnancy (age, education, partner status, social support [APGAR], stress events, self-esteem [Coopersmith], depressive symptomatology [BDI-II], and anxiety [SCL-90]) on anxiety symptomatology (SCL-90) in T2 and T3. Two additional linear regression analyses were performed to evaluate the influence of prenatal anxiety symptomatology (SCL-90) on postpartum depression symptoms (BDI-II), one for each postnatal period (T2, T3). The variables that predicted postpartum anxiety symptomatology in T2 were anxiety symptoms and lack of social support; in T3 they were anxiety symptoms, lack of a partner, and lack of social support. Prenatal anxiety symptoms predicted postpartum depressive symptomatology at both postpartum intervals (T2, T3). Untreated prenatal anxiety symptomatology is predictive of symptoms of anxiety and depression in the postpartum period, suggesting the need for timely detection and treatment. Women lacking social support or partners are a population particularly vulnerable to anxiety symptoms, and merit interventions that address these issues.

    Full Text Available 130 patients from a methadone maintenance treatment program agreed to complete Symptoms Checklist 90-Revised (SCL-90R and Alcohol Use Disorders Identification Test (AUDIT self-report scales. Scores higher than the proposed cut-score on SCL-90R scale were observed on depression, obsessions-compulsions, paranoid ideation, anxiety, anger-hostility, somatization, interpersonal sensitivity, and psychoticism subscales. In sum, 42.9% of our sample exhibited depressive symptomatology, 34.9% obsessive-compulsive symptoms, 29.1% somatization, 27.2% anxiety symptoms, 22.2% paranoid ideation, 19% phobic anxiety, 15.1% psychoticism, and 15.1% hostility and 11.9% presented with symptoms of interpersonal sensitivity. Mean score on AUDIT scale was 6.9±7.9. 63.0% of our participants scored below cut-off and were classified as having a low level of alcohol-related problems; 24.4% scored in the range of 8–15 which is an indication of alcohol abuse whereas 12.6% scored 16 and above indicative of serious abuse/addiction. Scores on AUDIT scale were positively correlated with length of time on methadone treatment, but not with length of time on drug use or age of our participants. Positive correlations were observed among AUDIT and SCL-90R scores, namely, with global severity index score, positive symptom distress index, positive symptom total, and all primary symptom dimensions subscales except phobic anxiety.

    In recent years, 90 Y has been considered as one of the best radionuclides for tumor radioimmunotherapy when chelated to tumor-associated antibodies. This evaluation is based on the superior properties of this radionuclide (suitable half-life, pure β-ray emitter of intermediate energy, stable daughters, and suitable chemical properties) and because it is available as a radionuclide generator product by decay of its 28a parent 90 Sr. The experimental conditions of 90 Sr- 90 Y generator are described. The elution efficiency of 90 Sr- 90 Y generator reaches 98%. One of the most important problems is the 90 Sr contamination breakthrough from the generator. The level of 90 Sr contamination must be controlled to the clinical standard. The cation exchange resin 732 (100-150 mesh) was successfully used for the separation of 90 Y from 90 Sr. The method used by the authors provides a 90 Y-HAc solution which is very simple and safe for administration to the patients. 90 Y was separated from 90 Sr almost completely, the level of the 90 Sr contamination per 740 MBq 90 Y product was only 0.74 kBq. However the toxicity of 90 Sr is extremely high, the human life-time permissible dose is 74 kBq, then 740 MBq of 90 Y is allowed to be administrated to a patient for 50-100 times

WMD was taken as the index of effect size, and meta-analysis was carried to study the difference of mental health between university teachers and norm of China, also within different genders and titles. 56 qualified literatures were included. The university teachers' total score, and the score of interpersonal sensitivity factor, anxiety factor, photic anxiety factor were higher than the norm of China, WMD were respectively 11.24, 0.21, 0.16 and 0.22. Male teachers' total score (-3.86), and the score of somatization (-0.07), depression (-0.06), anxiety (-0.07), photic anxiety (-0.06) were lower than female's. The score of primary title teachers interpersonal sensitivity (-0.09), photic anxiety (-0.10) were lower than intermediate title teachers'. The score of primary title teachers somatization (-0.19), obsessive-compulsive (-0.13), interpersonal sensitivity (-0.12), depression (- 0.12), anxiety (-0.10), paranoid ideation (-0.12), psychoticism (-0.09) were lower than senior vice title teachers'. The score of primary title teachers somatization(-0.23), depression (-0.16) were lower than senior title teachers'. The mean level of university teachers' mental health was lower than the norm of China. The overall situation of university teachers' mental health in China was not optimistic. The society and school should take targeted measures to improve university teachers' mental health.

    We examined the effects of home-delivered cognitive-behavioral therapy (CBT) for depression on anxiety symptoms in an ethnically diverse, low resource, and medically frail sample of rural, older adults. This was a secondary analysis of a randomized clincial trial with 134 rural-dwelling adults 65 years and older with decreased quality of life and elevated psychological symptomatology. Anxiety symptoms were assessed with the anxiety and phobic anxiety subscales of the Symptom Checklist-90-Revised (SCL-90-R). Compared to a minimal support control condition, CBT for depression resulted in significantly greater improvements in symptoms of anxiety and phobic anxiety from pre-treatment to post-treatment. Home-delivered CBT for depression can be an effective treatment for anxiety in a hard-to-reach older populations. Additional research should explore integrated anxiety and depression protocols and other treatment modalities, including bibliotherapy or telehealth models of CBT, to reduce costs associated with its in home delivery. Flexibility in administration and adaptations to the CBT protocol may be necessary for use with vulnerable, rural older adults.

    Some features of a novel 90 Sr- 90 Y generator which employs supported liquid membrane (SLM) to separate carrier-free 90 Y from 90 Sr present in the high level waste of the spent fuel of reactor are described. After ascertaining the purity of 90 Y particularly with respect to 90 Sr breakthrough, its complexation was studied with a few oxo/aza donor ligands, such as DTPA, EDTMP, DOTA, TETA and a cyclic phosphonate, CTMP. These studies were primarily carried out to adjudge the quality of the 90 Y obtained from a novel 90 Sr- 90 Y generator and ascertain its usability for labelling biomolecules such as antibodies and peptides. The DOTA complexes are most stable at 37 C in human serum; they appear to be ideal bifunctional chelating agent for use in radioimmunotherapy with 90 Y. (orig.)

    To assess the relationship between psychological distress and physical somatic symptoms as well as work environment conditions in the diverse population of dentists based in the Canary Islands (Spain). 203 dentists officially registered with the local General Dental Councils, returned the questionnaire delivered by mail. Participants provided information on demographic characteristics, self-constructed questions like self-perceived environmental working conditions (location, access, temperature, humidity and pollution). They also completed the Spanish versions of the 12-item General Health Questionnaire (GHQ-12) and the revised version of the Symptom Checklist (SCL-90-R). The GHQ-12 was used to assess psychological distress and the somatic physical symptoms were assessed with the 12-item somatic subscale extracted from the SCL-90-R. Three different linear regression models were constructed. Psychological distress was positively related to somatic symptoms in all the models even after adjusting for sex and age. This association also remained significant for self-perceived environmental working conditions in the two final models. 23% of the dentists had psychological distress. The mean score for the SCL-90-R somatic subscale was 0.55 points (Standard Deviation: 0.50). Self-perceived environmental working conditions were also associated with the strong relationship found between psychological distress and physical somatic symptoms among dentists.

    Yttrium-90 is a radioisotope of great interest in the field of Nuclear Medicine. It is considered one of the most important and most used radionuclides for radioimmunotherapeutical applications, especially promising for the treatment of certain types of cancer. Another important application of 90 Y is radio synovectomy. This radionuclide has a half-life of 64 hours, emits long range beta particles (maximum energy of 2.3 MeV) and decays, without intermediate nuclides, to a stable daughter. 90 Y may be obtained carrier-free, generated by the decay of its parent 90 Sr (half-life=28 years). 90 Sr is a product from uranium fission, and due to its long half-life, can be indefinitely used, which is certainly advantageous. It is present in great amounts, and needs to be processed and purified in order to be used as raw material for the generators. Generators of 90 Sr- 90 Y may thus be used during various months, due to 90 Sr long half-life. Several methods for the separation of 90 Y from 90 Sr by solvent extraction and ion exchange have been reported in literature. Thanks to its simplicity, ion exchange techniques have been more commonly used for this generator system. The main objective of this work was to develop a methodology for the preparation of 90 Sr- 90 Y generators, using cationic exchange resins. In such method, 90 Sr is strongly adsorbed in the resin and 90 Y is eluted by a 0.003 M EDTA solution. According to the quality control carried out, results showed that elution yields are greater than 65%, thus confirming the efficiency of the separation method used.

    Chronic fatigue following inflammatory diseases has been well documented. However, little is known about possible risk factors of chronic post-inflammatory fatigue. The aim of this study was to investigate whether chronic post-inflammatory fatigue after clinical remission of the disease sarcoidosis is associated with specific dimensions of personality, psychological symptoms and baseline levels of stress hormones. Thirty-seven non-fatigued and 33 fatigued patients in clinical remission of sarcoidosis were evaluated with the Temperament and Character Inventory-short form (TCI); the Symptom CheckList-90 (SCL), and the Checklist Individual Strength (CIS). Baseline levels of ACTH and cortisol were measured in plasma. Principal component analysis with orthogonal rotation (varimax) was conducted on all personality, psychological and stress hormone data in order to obtain a smaller set of components. Logistic regression was performed to associate these components with chronic post-inflammatory fatigue. Principal component analyses identified 5 components, of which two components were significantly associated with chronic post-inflammatory fatigue. The first component comprised the personality trait Harm Avoidance and all SCL-subscales except Sleep. The second component consisted of baseline levels ACTH and cortisol, and showed an inverse association with chronic post-inflammatory fatigue. The 3 other components, consisting of respectively SCL-Sleep, TCI-Novelty Seeking-Reward Dependence-Self Transcendence, and TCI-Persistence, were not significantly associated with chronic fatigue. Chronic post-inflammatory fatigue after clinical remission of sarcoidosis is associated with a triad of risk factors: a specific personality profile with profound neurotic characteristics in combination with high levels of psychological distress, and decreased baseline ACTH/cortisol levels.

    Adolescence is characterized by rapid physiological, social and cognititive changes. Aim of the present work is to study mental health of Saudi adolescent secondary school girls in Abha city, Aseer region, Saudi Arabia. A cross-sectional study was conducted in 10 secondary schools for girls using the Arabic version of the symptom-revised checklist 90 (SCL 90-R), a mental health questionnaire that was administered to the girls by fourth-year female medical students. The most prevalent mental symptoms in the 545 female students were phobic anxiety (16.4%), psycchoticism (14.8%), anxiety (14.3%), and somatization (14.2%). The prevalence of depression, paranoid ideation and interpersonal sensitivity amounted to 13.9%, 13.8% and 13.8%, respectively. The least prevalent mental symptoms were hostility (12.8%) and obsessive-compulsive behavior (12.3%). Overall, psychological symptoms (in terms of a positive global severity index) were found in 16.3% of the girls. In a multivariate logistic regression analysis, no significant relationship was found with sociodemographic factors. Psychological symptoms and disorders are prevalent in secondary school girls and health professionals need to be able to recognize, manage and follow-up mental health problems in young people. Further research is needed to explore the magnitude of the problem at the national level. (author)

    We investigated the relationship between internalized stigma of mental illness at baseline and depressive and psychotic symptoms 3 and 6 months later, controlling for baseline symptoms. Data on homeless veterans with severe mental illness (SMI) were provided by the Northeast Program Evaluation Center (NEPEC) Special Needs-Chronic Mental Illness (SN-CMI) study (Kasprow and Rosenheck, 2008). The study used the Internalized Stigma of Mental Illness (ISMI) scale to measure internalized stigma at baseline and the Symptom Checklist-90-R (SCL-90-R) to measure depressive and psychotic symptoms at baseline and 3 and 6 month follow-ups. Higher levels of internalized stigma were associated with greater levels of depressive and psychotic symptoms 3 and 6 months later, even controlling for symptoms at baseline. Alienation and Discrimination Experience were the subscales most strongly associated with symptoms. Exploratory analyses of individual items yielded further insight into characteristics of potentially successful interventions that could be studied. Overall, our findings show that homeless veterans with SMI experiencing higher levels of internalized stigma are likely to experience more depression and psychosis over time. This quasi-experimental study replicates and extends findings of other studies and has implications for future controlled research into the potential long-term effects of anti-stigma interventions on mental health recovery.

    Full Text Available Background: Internet addiction disorder is an interdisciplinary phenomenon and it has been studied from different viewpoints in terms of various sciences such as medicine, computer, sociology, law, ethics, and psychology. The aim of this study was to determine the association of psychiatric symptoms with Internet addiction while controlling for the effects of age, gender, marital status, and educational levels. It is hypothesized, that high levels of Internet addiction are associated with psychiatric symptoms and are specially correlated with obsessive-compulsive disorder symptoms. Methods: In a cross-sectional study, a total number of 250 students from Isfahan′s universities were randomly selected. Subjects completed the demographic questionnaire, the Young Diagnostic Questionnaire (YDQ and the Symptom Checklist-90-Revision (SCL-90-R. Data was analyzed using the multiple logistic regression method. Results: There was an association between psychiatric symptoms such as somatization, sensitivity, depression, anxiety, aggression, phobias, and psychosis with exception of paranoia; and diagnosis of Internet addiction controlling for age, sex, education level, marital status, and type of universities. Conclusions: A great percentage of youths in the population suffer from the adverse effects of Internet addiction. It is necessary for psychiatrists and psychologists to be aware of the mental problems caused by Internet addiction.

    Recently there has been interest in labelling monoclonal antibodies with therapeutic amounts of a pure beta emitting isotope. 90 Y offers many desirable features and may be conveniently and economically obtained from a 90 Sr- 90 Y generator. A potential hazard with this system is breakthrough of the parent 90 Sr which has a half life of 28 years and is an extremely toxic bone seeking isotope. Therefore it is essential that the daughter be completely separated from its parent. We have devised two simple techniques which allow us to monitor rapidly the amount of 90 Sr breakthrough and quantitate the 90 Y activity over a 5 log range. (author)

    The purpose of this study was to assess the amount of psychological stress experienced by didactic phase, physician assistant (PA) students. The Symptom Checklist-90-R (SCL-90-R) survey was administered to 81 students in 2011 during the first two didactic phase semesters at two PA programs. Using ANOVA and t-tests, several variables were analyzed for significance. The SCL-90-R results portray that a significant proportion of the students from both programs reported elevated levels of stress during the first and second semester of the didactic year. Although several significant levels were noted throughout this study, it is not known how these scores from PA students would compare to other medical and/or nonmedical graduate students. Additional studies of stress from both medical and nonmedical graduate students would be beneficial for comparison to PA students.

    Strontium-90 has been determined by radiochemical separation techniques in environmental samples. These techniques, of course, cannot separate the two strontium radionuclides from each other of from stable strontium. Consequently the end product of the chemical separation contains all strontium isotopes in SrCO 3 . The beta particules emitted by 90 Sr are absorbed by the SrCO 3 precipitate. This is the main source of error in the activity measurement. It has been prepared sources of 90 Sr in SrCO 3 in order to determinate the counting efficiency and autoabsorption curve. Also detection efficiencies have been calibrated using known activities of 90 Y and equilibrium mixture of 90 Sr+ 90 Y in the same geometry than our samples. The activity of 90 Sr by ingrowth of 90 Y has been calculated by our computer program. (author). 2 figs., 3 refs

    Dysphoria has recently been conceptualized as a complex emotional state that consists of discontent and/or unhappiness and a predominantly externalizing mode of coping with these feelings. The Nepean Dysphoria Scale (NDS) was developed on the basis of this model of dysphoria and used in this clinical study to ascertain the specificity of the relationships between dysphoria and relevant domains of psychopathology. Ninety-six outpatients completed the NDS, Symptom Checklist 90-Revised (SCL-90R) and Depression, Anxiety, Stress Scales, 21-item version (DASS-21). The scores on the NDS subscales (Discontent, Surrender, Irritability and Interpersonal Resentment) and total NDS scores correlated significantly with scores on the DASS-21 scales and relevant SCL-90R subscales. Multiple regression analyses demonstrated the following: DASS-21 Depression and Stress each had unique relationships with NDS Discontent and Surrender; DASS-21 Anxiety had a unique relationship with NDS Discontent; SCL-90R Hostility and Paranoid Ideation and DASS-21 Stress each had unique relationships with NDS Irritability; and SCL-90R Paranoid Ideation and DASS-21 Stress, Depression and Anxiety each had unique relationships with NDS Interpersonal Resentment. These findings support the notion that dysphoria is a complex emotional state, with both non-specific and specific relationships with irritability, tension, depression, paranoid tendencies, anxiety, hostility and interpersonal sensitivity. Conceptual rigor when referring to dysphoria should be promoted in both clinical practice and further research.

    Little has been known regarding the correlates of severe insomnia in major depressive disorder (MDD). This post-hoc analysis aimed to examine the sociodemographic and clinical correlates of severe insomnia in psychotropic drug-free, Asian adult outpatients with MDD. Participants were psychotropic drug-free patients with MDD, aged 18-65 years. By using the Symptom Checklist-90 Items, Revised (SCL-90-R), a score of 4 (severe distress) on any one of three insomnia items was defined as severe insomnia. Other measures included the Montgomery-Asberg Depression Rating Scale (MADRS), the Fatigue Severity Scale (FSS), the nine psychopathology subscales of SCL-90-R, the Physical and Mental Component Summaries of Short Form Health Survey (SF-36 PCS and SF-36 MCS), and the Sheehan Disability Scale (SDS). Of 528 participants, their mean age being 39.5 (SD=13.26) years, 64.2% were females, and 239 (45.3%) had severe insomnia. The logistic regression model revealed that low educational qualifications (less than secondary school completion), high SCL-90-R Depression scores, high SCL-90-R Anxiety scores, and low SF-36 PCS scores were independently correlated with severe insomnia (p'sdepression and anxiety severity, and poor physical health. These findings may implicate the treatment of comorbid MDD and severe insomnia, for example, sleep hygiene education, pharmacological treatment. Copyright © 2015 Elsevier B.V. All rights reserved.

    To study the psychological aspects of tinnitus patients, to analyze the distribution of psychologic obstacle in tinnitus patients, and then to provide information for diagnosing and treating tinnitus clinically. All patients were detected their frequency and loudness of tinnitus. Then they were evaluated by symptom checklist 90 (SCL-90), life satisfaction scale, Pittsburgh sleep quality index (PSQI) and tinnitus handicap inventory (THI). All data were analyzed with statistical software SPSS11.0. (1)There was no straight line correlation between frequency, loudness of tinnitus and the patient's scores from SCL-90, life satisfaction rating scale (LSR), life satisfaction index A (LSIA), LSIB, PSQI, THI. (2) To 76 tinnitus patients, some factors of SCL-90 were higher than internal nom. Compared with internal nom, tinnitus patients' score of LSR, LSIA and LSIB were all lower than it. Many of tinnitus patients had sleep disorder, the ratio was higher than internal nom. (3) Grouping these patients, based on the score of THI. To THI four grade group and THI five grade group, their satisfaction of lives were lower, some factors of SCL-90 were higher than internal nom. To THI five grade group, the ratio about sleep disorder was higher than internal nom. There is no straight line correlation between frequency, loudness of tinnitus and the patient's scores from SCL-90, LSR, LSIA, LSIB, PSQ1, THI. Grouping based on the score of THI, the groups of THI four grade and THI five grade are approved that they have psychologic obstacle obviously, they should be paid close attention.

    BACKGROUND AND OBJECTIVES: Adolescence is characterized by rapid physiological, social and cognititive changes. Aim of the present work is to study mental health of Saudi adolescent secondary school girls in Abha city, Aseer region, Saudi Arabia. METHODS: A cross-sectional study was conducted in 10 secondary schools for girls using the Arabic version of the symptom-revised checklist 90 (SCL 90-R), a mental health questionnaire that was administered to the girls by fourth-year female medical students. RESULTS: The most prevalent mental symptoms in the 545 female students were phobic anxiety (16.4%), psychoticism (14.8%), anxiety (14.3%), and somatization (14.2%). The prevalence of depression, paranoid ideation and interpersonal sensitivity amounted to 13.9%, 13.8% and 13.8%, respectively. The least prevalent mental symptoms were hostility (12.8%) and obsessive-compulsive behavior (12.3%). Overall, psychological symptoms (in terms of a positive global severity index) were found in 16.3% of the girls. In a multivariate logistic regression analysis, no significant relationship was found with sociodemographic factors. CONCLUSION: Psychological symptoms and disorders are prevalent in secondary school girls and health professionals need to be able to recognize, manage and follow-up mental health problems in young people. Further research is needed to explore the magnitude of the problem at the national level. PMID:19584586

    Depression may essentially influence cognitive function contributing to poor school performance. The present study undertakes to determine the existence and strength of correlation between depressive symptomatology and other mental conditions with the acquired level of understanding of Newtonian physics taught in schools. The current study recruited 490 students (262 girls, 228 boys) attending the first semester of the Greek Second Grade of General Lyceum School. Force Concept Inventory (FCI) tested the depth of the students’ understanding of Newtonian Physics. Symptom Checklist-90-R assessed general mental status. The tests took place in the classroom during a 1 h session. Low FCI scores significantly correlated with mental conditions, with depression ranking first. Girls had higher scores in all nine symptoms scales of SCL-90 and lower FCI scores. Stepwise regression models proved that the gender effect on FCI could be effectively explained through the significant effect of depression. An understanding of Newtonian physics among high school students may be restricted by common problematic mental conditions, with depression being the greatest among all. Further research, using a more systematic approach to measure depression among adolescents with poor understanding of physics, would help to elucidate the nature of the effect.

  3. Discriminating real victims from feigners of psychological injury in gender violence: Validating a protocol for forensic setting

    Full Text Available Standard clinical assessment of psychological injury does not provide valid evidence in forensic settings, and screening of genuine from feigned complaints must be undertaken prior to the diagnosis of mental state (American Psychological Association, 2002. Whereas psychological injury is Post-traumatic Stress Disorder (PTSD, a clinical diagnosis may encompass other nosologies (e.g., depression and anxiety. The assessment of psychological injury in forensic contexts requires a multimethod approach consisting of a psychometric measure and an interview. To assess the efficacy of the multimethod approach in discriminating real from false victims, 25 real victims of gender violence and 24 feigners were assessed using a the Symptom Checklist-90-Revised (SCL-90-R, a recognition task; and a forensic clinical interview, a knowledge task. The results revealed that feigners reported more clinical symptoms on the SCL-90-R than real victims. Moreover, the feigning indicators on the SCL-90-R, GSI, PST, and PSDI were higher in feigners, but not sufficient to provide a screening test for invalidating feigning protocols. In contrast, real victims reported more clinical symptoms related to PTSD in the forensic clinical interview than feigners. Notwithstanding, in the forensic clinical interview feigners were able to feign PTSD which was not detected by the analysis of feigning strategies. The combination of both measures and their corresponding validity controls enabled the discrimination of real victims from feigners. Hence, a protocol for discriminating the psychological sequelae of real victims from feigners of gender violence is described.

    90 Y of high specific activity and very high radionuclidic purity (>99.998%) is essential for targeted therapy. Since the current methods used for the preparation of 90 Y from 90 Sr are not adaptable for use in a central/hospital radiopharmacy, a simple 90 Sr- 90 Y generator system based on electrochemical separation technique was developed. Methods: Two-cycle electrolysis procedure was developed for separation of 90 Y from 90 Sr in nitrate solution. The first electrolysis was performed for 90 min in 90 Sr(NO 3 ) 2 feed solution at pH 2-3 at a potential of -2.5V with 100-200 mA current using platinum electrodes. The second electrolysis was performed for 45 min in 3 mM HNO 3 at a potential of -2.5V with 100 mA current. In this step, the cathode from the first electrolysis containing 90 Y was used as anode along with a fresh circular platinum electrode as cathode. The 90 Y deposited on the circular cathode after the second electrolysis was dissolved in acetate buffer to obtain 90 Y acetate, suitable for radiolabeling. Results: >96% recovery of 90 Y could be achieved in each cycle, with an overall decay corrected yield of >90%. The recovered 90 Y had high radionuclidic purity with barely 30.2±15.2 kBq (817±411 nCi) of 90 Sr per 37 GBq (1 Ci) of 90 Y (0.817±0.411 ppm). Consistent and repeated separation could be demonstrated using up to 1.85 GBq (50 mCi) of 90 Sr. The generator was named 'Kamadhenu,' the eternally milk-yielding Indian mythological cow. Conclusions: A technique suitable for adaptation at central radiopharmacies for obtaining therapeutic quantities of pure 90 Y has been developed

    Psychological complaints were investigated in two samples of 60 and 138 in-patients suffering from chronic tinnitus. We administered the Tinnitus Questionnaire (TQ), a 52-item self-rating scale which differentiates between dimensions of emotional and cognitive distress, intrusiveness, auditory perceptual difficulties, sleep disturbances and somatic complaints. The test-retest reliability was .94 for the TQ global score and between .86 and .93 for subscales. Three independent analyses were conducted to estimate the split-half reliability (internal consistency) which was only slightly lower than the test-retest values for scales with a relatively small number of items. Reliability was sufficient also on the level of single items. Low correlation between the TQ and the Hopkins Symptom Checklist (SCL-90-R) indicate a distinct quality of tinnitus-related and general psychological disturbances.

    To determine the psychiatric symptom assessment of patients seeking treatment for irritable bowel syndrome (IBS) and to demonstrate the presence of more complicated psychiatric disorders. The participants were recruited from patients who were attending internal medicine and gastroenterology clinics and who fullfilled the Rome III criteria for IBS. Fifty patients with IBS (IBS group) and 50 patients with complaints other than gastrointestinal symptoms (control group) were randomly selected. All participants were screened by the Structured Clinical Interview for DSM-IV (SCID-I), Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI), Symptom Check list - 90 (Revised) [SCL-90-R]. Seventeen patients (34%) and three control subjects (6%) had at least one psychiatric diagnosis (p = 0.001). Global severity index (GSI) total scores and SCL-90-R items were significantly higher in the IBS group than the control group (0.92 +/- 0.46 vs 0.358 +/- 0.19, p IBS group than the control group (p disorders diagnosed with SCID-I were significantly higher in the IBS group (34% vs 6%) [p = 0.001]. Among the Axis-I disorders, somatoform and anxiety disorders were higher in the patient group than in the control subjects (p = 0.002 and p = 0.0057) whereas there was no difference for mood disorders (p = 0.204). Seven (14%) of the patients and two (4%) of the control subjects had at least one Axis-II psychiatric disorder diagnosed with SCID-II without any significance (p = 0.159). These findings suggest that except for mood and personality disorders, almost all psychiatric symptoms and disease co-morbities with IBS are higher than in the sample without IBS. We can easily use SCL-90-R, BAI and BDI in internal medicine and gastroenterology clinics to detect psychiatric symptom levels and then to refer patients to a psychiatrist for further evaluation and treatment.

    The purpose of this study is two-fold: (a) to study the concomitant relationships between psychopathological symptoms, cooperation, social skills, and other personality traits; and (b) to identify the predictive variables of psychopathological symptoms. The sample consists of 322 adolescents aged 14 to 17 years old. This study uses correlational methodology. In order to assess psychopathological symptoms, cooperation, social skills, and personality traits, the following scales are used: the Symptom Checklist (SCL-90-R; Derogatis, 1983), the Cooperativeness Scale (CS; Rigby, Cox, and Black, 1997), the MESSY social skills scale (Matson, Rotatori, and Helsel, 1983), and the TPT Personality Test (Corral, Pamos, Pereña, and& Seisdedos, 2002). Pearson coefficients suggest that adolescents with many psychopathological symptoms have low levels of cooperative behaviors and social skills. They also score high in inappropriate assertiveness, impulsiveness, overconfidence, and jealousy-withdrawal and have low levels of emotional stability, sociability, and responsibility. Through multiple regression analyses, the following variables were identified as predictors of psychopathological symptoms: jealousy-withdrawal, low social integration, impulsiveness, and low self-concept. The role played by intervention programs promoting socio-emotional development to prevent psychopathological symptoms and enhance mental health is discussed.

    To observe the effect of psychosocial factors on the level of cholyglycine(CG) before childbirth, 69 gravidas were investigated by using the Gravida General Situation Questionnaire, the A Strait Behavior Questionnaire, and Symptom Checklist-90(SCL-90) in the term of pregnancy till giving birth. The data were subjected to statistical analysis. The result showed that: (1) The level of CG was significantly higher in the group with A-behavior than that in the group with B-or M-Behavior(P<0.05); (2) The incidence of post partum complication in the high CG group (8%) was significantly higher than that in the low CG group (P<0.01); (3)The gestational period, the relation with parents of gravidas husband and SCL-90 panic score were main influencing factors on the level of CG . Besides physiological factors' effecting on CG, psychosocial factors should also be paid attention to. (authors)

    Objective: To compare the long-term quality of life in esophageal carcinoma patients treated with continuous accelerated hyperfractionated (CAHF) and late-course accelerated hyperfractionated (LCAF) radiotherapy. Methods: Subjective and Objective Management Analysis (SOMA) scale, Symptom Checklist 90 (SCL-90) and Life Satisfaction Index A (LSIA) questionnaire were mailed to the long survivors in both CAHF and LCAF groups to assess the long-term quality of life including symptoms, psychological status and life satisfaction. Results: There was no significant difference between the two groups in the score of quality of life such as late radiation reaction, SCL-90 and LSI-A. Conclusions: 1. It is reasonable to assess the quality of life with these scales for esophageal carcinoma patients treated with radiotherapy, 2. Preliminary results demonstrate that there is no significant difference in long-term quality of life between the CAHF and LCAF radiotherapy groups, 3. Methods of evaluating the long-term quality of life for esophageal carcinoma patients treated with radiotherapy needs further investigation, preferably involving more patients and setting on control arm

  12. Hanford isotope project strategic business analysis yttrium-90 (Y-90)

    International Nuclear Information System (INIS)

    1995-10-01

    The purpose of this analysis is to address the short-term direction for the Hanford yttrium-90 (Y-90) project. Hanford is the sole DOE producer of Y-90, and is the largest repository for its source in this country. The production of Y-90 is part of the DOE Isotope Production and Distribution (IP and D) mission. The Y-90 is ''milked'' from strontium-90 (Sr-90), a byproduct of the previous Hanford missions. The use of Sr-90 to produce Y-90 could help reduce the amount of waste material processed and the related costs incurred by the clean-up mission, while providing medical and economic benefits. The cost of producing Y-90 is being subsidized by DOE-IP and D due to its use for research, and resultant low production level. It is possible that the sales of Y-90 could produce full cost recovery within two to three years, at two curies per week. Preliminary projections place the demand at between 20,000 and 50,000 curies per year within the next ten years, assuming FDA approval of one or more of the current therapies now in clinical trials. This level of production would incentivize private firms to commercialize the operation, and allow the government to recover some of its sunk costs. There are a number of potential barriers to the success of the Y-90 project, outside the control of the Hanford Site. The key issues include: efficacy, Food and Drug Administration (FDA) approval and medical community acceptance. There are at least three other sources for Y-90 available to the US users, but they appear to have limited resources to produce the isotope. Several companies have communicated interest in entering into agreements with Hanford for the processing and distribution of Y-90, including some of the major pharmaceutical firms in this country

    Recent UNAIDS '90-90-90' targets propose that to end the HIV epidemic by 2030, 90% of persons living with HIV (PLWH) worldwide should know their diagnosis, 90% of diagnosed PLWH should be on antiretroviral therapy (ART) and 90% of PLWH on ART should be virally suppressed by 2020. We sought to quantify the epidemiological impact of achieving these targets in India. We constructed a dynamic-transmission model of the Indian HIV epidemic to project HIV infections and AIDS-related deaths that would occur in India over 15 years. We considered several scenarios: continuation of current care engagement (with early ART initiation), achieving 90-90-90 targets on time and delaying achievement by 5 or 10 years. In the base case, assuming continuation of current care engagement, we project 794 000 (95% uncertainty range (UR) 571 000-1 104 000) HIV infections and 689 000 (95% UR 468 000-976 000) AIDS-related deaths in India over 15 years. In this scenario, nearly half of PLWH diagnosed would fail to achieve viral suppression by 2030. With achievement of 90-90-90 targets, India could avert 392 000 (95% UR 248 000-559 000) transmissions (48% reduction) and 414 000 (95% UR 260 000-598 000) AIDS-related deaths (59% reduction) compared to the base-case scenario. Furthermore, fewer than 20 000 (95% UR 12 000-30 000) HIV infections would occur in 2030. Delaying achievement of targets resulted in a similar reduction in HIV incidence by 2030 but at the cost of excess overall infections and mortality. India can halve the epidemiological burden of HIV over 15 years with achievement of the UNAIDS 90-90-90 targets. Reaching the targets on time will require comprehensive healthcare strengthening, especially in early diagnosis and treatment, expanded access to second-line and third-line ART and long-term retention in care.

    An exploration of nursing care for patients with benign prostatic hyperplasia (BPH) treated using 90 Sr- 90 Y through the rectum was carried out . The treatment result and nursing experience in 90 cases were reported in this paper. Before the therapy nurses explained the method and principle of this treatment to the patients for the sake of increasing their confidence and to help them complete the treatment course successfully. During the radiotherapy, nurses practiced strictly radiation protection principles and operating instructions. They assisted the patients to have a healthy life style and good diet . The result of treatment indicated that the total effectiveness rate was 96.7%. The symptoms of lower urinary obstruction were improved evidently and the life quality of the patients elevated. Observation of clinical system confirmed that 90 Sr- 90 Y may be a new treatment method of BPH with benefits of safe irradiation dos, easy operation, non-traumatization, painlessness, and remarkable curative effects. However, it should be stressed that nursing care plays a pivotal role in the treatment result. (authors)

    Abstract Background Recently, we showed that assumptions from complex system theory seem applicable in the field of psychiatry. This means that indicators of critical slowing down in the system signal the risk for a critical transition in the near future. In the current study we wanted to explore whether the principle of critical slowing down may also be informative to anticipate on the type of symptoms that individuals are most likely to develop. This is relevant as it may lead to personalized prediction of risk of whether adolescents with mixed complaints are most likely to develop either depression, anxiety, somatic or psychotic symptoms in the near future. For example, we hypothesized that critical slowing down in feeling ‘suspicious’ more strongly indicates risk for a future transition to psychotic symptoms, while critical slowing down in feeling ‘down’ more strongly indicates risk for a transition to depressive symptoms. Methods We examined this in a population of adolescents (most between 15 and 18 years) as adolescents are an at-risk group for the development of psychopathology. At baseline experience sampling was performed for 6 days, 10 measurements a day. Affect items were used to assess autocorrelation as an indicator of ‘critical slowing down’ of the system. At baseline and follow-up SCL-90 questionnaires were administered. In total, 147 adolescents participated both in baseline and follow-up measures and showed increases in at least one of the defined symptom dimensions. We examined whether autocorrelation was positively associated with the size of symptom transition and whether different type of transitions (in depression, anxiety etc.) were differentially predicted by autocorrelations in specific affect states. Results The analyses were done very recently, and findings have not been presented before. We found both shared and specific indicators of risk in the development for transition to various symptom dimensions. First

    Recent research indicates an association between obesity and symptoms of psychopathology, the nature of which remains obscure. This study examined the confounding role of behavioral factors on this association. One hundred and forty-two overweight/obese subjects who sought treatment for obesity, of both genders (51 males and 91 females), 18 to 64 years old and 139 normal-weight controls of both genders (41 males and 98 females), 18 to 63 years old, were enrolled in this study. We measured psychopathology features, using the Symptom Checklist 90-Revised (SCL-90-R), dietary habits, using the MedDietScore (MDS) questionnaire, and physical activity, using the International Physical Activity Questionnaire (IPAQ). A series of regression models were used to estimate the mediation of dietary patterns and physical activity on the obesity-psychopathology association. The associations between obesity and depression (β=0.32/β=0.15), obsession-compulsion (β=0.03/β=-0.13), anxiety (β=-0.25/β=-0.12), interpersonal sensitivity (β=0.08/β=-0.04) and psychoticism (β=-0.01/ β=0.025) are accounted for by sedentary behavior and Mediterranean diet. Our data suggest that modifiable behavioral factors such as sedentary time and dietary patterns positively affect the association between obesity and symptoms of psychopathology.

    The aim of this review is to critically appraise the evidence on measurement properties of self-report questionnaires measuring somatization in adult primary care patients and to provide recommendations about which questionnaires are most useful for this purpose. We assessed the methodological quality of included studies using the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) checklist. To draw overall conclusions about the quality of the questionnaires, we conducted an evidence synthesis using predefined criteria for judging the measurement properties. We found 24 articles on 9 questionnaires. Studies on the Patient Health Questionnaire-15 (PHQ-15) and the Four-Dimensional Symptom Questionnaire (4DSQ) somatization subscale prevailed and covered the broadest range of measurement properties. These questionnaires had the best internal consistency, test-retest reliability, structural validity, and construct validity. The PHQ-15 also had good criterion validity, whereas the 4DSQ somatization subscale was validated in several languages. The Bodily Distress Syndrome (BDS) checklist had good internal consistency and structural validity. Some evidence was found for good construct validity and criterion validity of the Physical Symptom Checklist (PSC-51) and good construct validity of the Symptom Check-List (SCL-90-R) somatization subscale. However, these three questionnaires were only studied in a small number of primary care studies. Based on our findings, we recommend the use of either the PHQ-15 or 4DSQ somatization subscale for somatization in primary care. Other questionnaires, such as the BDS checklist, PSC-51 and the SCL-90-R somatization subscale show promising results but have not been studied extensively in primary care.

    Full Text Available In 2014, the Joint United Nations Program on HIV/AIDS (UNAIDS issued treatment goals for human immunodeficiency virus (HIV. The 90-90-90 target specifies that by 2020, 90% of individuals living with HIV will know their HIV status, 90% of people with diagnosed HIV infection will receive antiretroviral treatment (ART, and 90% of those taking ART will be virally suppressed. Consistent methods and routine reporting in the public domain will be necessary for tracking progress towards the 90-90-90 target.For the period 2010-2016, we searched PubMed, UNAIDS country progress reports, World Health Organization (WHO, UNAIDS reports, national surveillance and program reports, United States President's Emergency Plan for AIDS Relief (PEPFAR Country Operational Plans, and conference presentations and/or abstracts for the latest available national HIV care continuum in the public domain. Continua of care included the number and proportion of people living with HIV (PLHIV who are diagnosed, on ART, and virally suppressed out of the estimated number of PLHIV. We ranked the described methods for indicators to derive high-, medium-, and low-quality continuum. For 2010-2016, we identified 53 national care continua with viral suppression estimates representing 19.7 million (54% of the 2015 global estimate of PLHIV. Of the 53, 6 (with 2% of global burden were high quality, using standard surveillance methods to derive an overall denominator and program data from national cohorts for estimating steps in the continuum. Only nine countries in sub-Saharan Africa had care continua with viral suppression estimates. Of the 53 countries, the average proportion of the aggregate of PLHIV from all countries on ART was 48%, and the proportion of PLHIV who were virally suppressed was 40%. Seven countries (Sweden, Cambodia, United Kingdom, Switzerland, Denmark, Rwanda, and Namibia were within 12% and 10% of achieving the 90-90-90 target for "on ART" and for "viral suppression

    90 Y (T 1/2 =64.2 h) finds several applications in nuclear medicine. It is formed from the decay of 90 Sr which has a long half-life of 28.8 years. 90 Sr can be used as a long-lasting source for the production of carrier-free 90 Y. 90 Sr itself is abundantly available in high level waste (HLW) of PUREX origin. The present studies deal with the separation of pure 90 Sr from HLW and the subsequent separation of 90 Y from 90 Sr. Actinides and some of the fission products like lanthanides, zirconium, molybdenum and cesium were first removed from the HLW using methods based on solvent extraction and ion-exchange studied earlier in our laboratory. The resulting waste solution was used as a feed for the present process. The separation of 90 Sr from HLW was based on radiochemical method which involved a repeated scavenging with ferric hydroxide followed by strontium carbonate precipitation. The separation of 90 Y from 90 Sr was achieved by membrane separation technique. A compact generator is developed for this separation using a commercially available polytetrafluoroethylene (PTFE) membrane, impregnated with indigenously synthesised 2-ethylhexyl 2-ethylhexyl phosphonic acid (KSM-17). Generator system overcomes the drawbacks associated with conventional solvent extraction and ion-exchange based generators. The product is in chloride form and is suitable for complexation studies. After gaining an operating experience of ∼3 years in generating carrier-free 90 Y at 2 mCi level for initial studies in radiotherapeutic applications, the process was scaled up for the production of about 12 mCi of 90 Y to be used for animal studies before its application to patients. Radiochemical and chemical purity of the product was critically assayed by radiometry, ICP-AES, etc. The process is amenable for further scaling up. (author)

    Three different 90Y internally administered radionuclide therapies are currently used in both standard-of-care and clinical trial procedures atMD Anderson Cancer Center. TheraSphere and SIR-Spheres therapies utilize 90Y-labeled microspheres, while Zevalin is an 90Y-labeled radioimmunotherapeutic agent. Several publications have indicated radionuclidic impurities resulting from 90Y production methods. The 90Y in SIR-Spheres and Zevalin are produced from a 90Sr/90Y generator, which leaves measurable quantities of 90Sr in the final product. TheraSphere 90Y is produced in a nuclear reactor which results in a large number of impurities, most notably 88Y and 91Y. Product information sheets reference these impurities with specific limits given. These limits represent a tiny fraction of the total product activity, and in the case of TheraSphere and SIR-Spheres gamma-emitting impurities, this has been verified in the literature. An analysis of 90Sr impurities in SIR-Spheres and Zevalin is presented in this paper. Impurity quantities were found to be within the vendors’ documented limits.

    Introduction UNAIDS “90-90-90” strategy calls for 90% of HIV-infected individuals to be diagnosed by 2020, 90% of whom will be on anti-retroviral therapy (ART) and 90% of whom will achieve sustained virologic suppression. Reaching these targets by 2020 will reduce the HIV epidemic to a low-level endemic disease by 2030. However, moving the global response towards this universal test and treat model will pose huge challenges to public health systems in resource-limited settings, including global and local supply chain systems. These challenges are especially acute in Africa, which accounts for over 70% of the persons affected by HIV. Discussion From a supply chain perspective, each of the “90's” has possible complications and roadblocks towards realizing the promise envisioned by 90-90-90. For instance, ensuring that 90% of HIV-infected persons know their status will require a large increase in access to HIV tests compared with what is currently available. To ensure that there are enough anti-retrovirals available to treat the nearly 25 million people that will require them by 2020 represents a near doubling of the ARV supplied to treat the 13 million currently on treatment. Similarly, to monitor those on treatment means an unprecedented scale-up of viral load testing throughout Africa. Conclusions Larger issues include whether the capacity exists at the local level to handle these commodities when they arrive in the most severely affected countries, including considerations of the human resources and costs needed to make this strategy effective. We believe that such “real world” analysis of proposed strategies and policies is essential to ensure their most effective implementation. PMID:27370169

    Full Text Available The risk of stroke after a transient ischemic attack (TIA for patients with a positive diffusion-weighted image (DWI, i.e., transient symptoms with infarction (TSI, is much higher than for those with a negative DWI. The aim of this study was to validate the predictive value of a web-based recurrence risk estimator (RRE; http://www.nmr.mgh.harvard.edu/RRE/ of TSI.Data from the prospective hospital-based TIA database of the First Affiliated Hospital of Zhengzhou University were analyzed. The RRE and ABCD2 scores were calculated within 7 days of symptom onset. The predictive outcome was ischemic stroke occurrence at 90 days. The receiver-operating characteristics curves were plotted, and the predictive value of the two models was assessed by computing the C statistics.A total of 221 eligible patients were prospectively enrolled, of whom 46 (20.81% experienced a stroke within 90 days. The 90-day stroke risk in high-risk TSI patients (RRE ≥4 was 3.406-fold greater than in those at low risk (P <0.001. The C statistic of RRE (0.681; 95% confidence interval [CI], 0.592-0.771 was statistically higher than that of ABCD2 score (0.546; 95% CI, 0.454-0.638; Z = 2.115; P = 0.0344 at 90 days.The RRE score had a higher predictive value than the ABCD2 score for assessing the 90-day risk of stroke after TSI.

    Among the more attractive radionuclides for therapeutic applications is yttrium-90. Its relatively short half-life (64.0h), maximum beta energy (2.28 MeV) make it well suited for a variety of applications, ranging from the radiolabeling of antibodies for tumor therapy to the production of radiolabeled particles for the treatment of liver malignancies. Yttrium-90 results from the decay of strontium-90 (28y) and decays to a stable daughter ( 90 Zr) and has no γ-ray, what makes this nuclide very attractive for therapeutic applications. 90 Y is produced through a generator system, from the decay of 90 Sr. Before it can safely employed in clinical applications, the 90 Y must be made essentially free of 90 Sr, an isotope known to cause bone marrow suppression. The objective of this work is to develop 90 Sr- 90 Y generator using a cation exchange method resin. This method was the most effects for the separation of 90 Y and 90 Sr. 90 Sr is strongly adsorbed in the resin and 90 Y is eluted in 0.003M EDTA. The generator efficiency and radionuclide control results were also evaluated using 85 Sr (γ-ray emitter). The generator was developed, using AG 50WX8 exchange resin converted to the Na+ form and then conditioned with 0.003M EDTA solution (pH=4.8). The quality control showed that 90 Y had no 8 '5Sr impurities, inside the detection limits of the detector. The results presented here are very promising, showing that the methodology is able to separate the two nuclides, with low quantities of 90 Sr impurity and satisfactory elution yields. (author)

    The aim of the study is to assess a mediational pathway, which includes patients' sex, personality traits, age of onset of gambling disorder (GD) and gambling-related variables. The South Oaks Gambling Screen, the Symptom Checklist (SCL-90-R) and the Temperament and Character Inventory-R were administered to a large sample of 1632 outpatients attending a specialized outpatient GD unit. Sociodemographic variables were also recorded. A Structural Equation Model was adjusted to assess the pathway. Age of onset mediated between personality profile (novelty seeking and self-transcendence) and GD severity and depression symptoms (measured by SCL-90-R). Sex had a direct effect on GD onset and depression symptoms: men initiated the GD earlier and reported fewer depression symptoms. Age of onset is a mediating variable between sex, personality traits, GD severity and depression symptoms. These empirical results provide new evidence about the underlying etiological process of dysfunctional behaviors related to gambling, and may help to guide the development of more effective treatment and prevention programs aimed at high-risk groups such as young men with high levels of novelty seeking and self-transcendence.

    Full Text Available Objective: Premenstrual syndrome is a common disorder experienced by up to 50% of women during reproductive age. The prevalence of severe form of PMS (PMDD is 3 % to 8%. Psychiatric disorders in PMS patients have resulted in significant morbidity and in some cases caused resistance to the treatment process Material and Method: 390 participants (264 with PMS/PMDD, and 126 healthy students of University of Guilan who completed the demographic questionnaire, daily symptom rating (DSR and the checklist 90-revised (SCL-90-R took part in this study. This study was conducted using a cross sectional method. Results: According to repeated measure variance, the mean scores of psychiatric symptoms (Depression, Anxiety, Aggression, Interpersonal sensitivity in the PMS group were significantly higher than the healthy group (p< 0/05, and increase in severity of PMS from mild to severe was accompanied by increase in mean score of these subscales. There was a significant difference in mean score of depression, anxiety, aggression and interpersonal sensitivity between the 3rd and the 13th day of the cycle. Significant effect of the DSR grouping (PMS and Healthy group and time interaction emerged in interpersonal sensitivity and aggression, significant effect on the DSR grouping (Mild, Moderate, Severer and time interaction demonstrated in interpersonal sensitivity. Conclusion: Patients with prospective confirmed PMDD seemed to suffer from psychiatric symptoms. Therefore, recognizing co-morbid psychiatric symptoms in patients with PMDD is of prime importance. All healthcare providers should be sensitive to mental status of women with PMS.

    While the extraction paper chromatography (EPC) technique constitutes a novel paradigm for the determination of few Becquerels of 90 Sr in MBq quantities of 90 Y obtained from 90 Sr/ 90 Y generator, validation of the technique is essential to ensure its usefulness as a real time analytical tool. With a view to explore the relevance and applicability of EPC technique as a real time quality control (QC) technique for the routine estimation of 90 Sr content in generator produced 90 Y, a systematic validation study was carried out diligently not only to establish its worthiness but also to broaden its horizon. The ability of the EPC technique to separate trace amounts of Sr 2+ in the presence of large amounts of Y 3+ was verified. The specificity of the technique for Y 3+ was demonstrated with 90 Y obtained by neutron irradiation. The method was validated under real experimental conditions and compared with a QC method described in US Pharmacopeia for detection of 90 Sr levels in 90 Y radiopharmaceuticals. (author)

    This study aimed to investigate psychosocial functioning and different dimensions of theory of mind (ToM) in people with bulimia nervosa (BN) and Eating Disorder Not Otherwise Specified-BN type (EDNOS-BN). Psychosocial functioning and ToM were assessed in a sample of young adult females, 16 BN and 16 EDNOS-BN outpatients and 16 healthy controls (HCs). They were assessed using the Eating Disorder Inventory-Symptom Checklist-2 (EDI-2 SC) for evaluating psychological traits associated with eating disorders; the Symptom Checklist-90-Revised (SCL-90-R) for evaluating psychopathological status; and the Theory of Mind Assessment Scale (Th.o.m.a.s.), a semi-structured interview aimed at assessing a person's different dimensions of ToM. The BN and EDNOS-BN groups exhibited worse performance than the control group on all dimensions of the SCL-90-R, and on all dimensions of the EDI-2 SC. The only difference for perfectionism was that BN obtained higher scores than EDNOS-BN group. Our results also revealed an impairment of third-person and second-order ToM in patients with bulimia (BN and EDNOS-BN) with respect to control subjects. These preliminary data have important implications for future empirical work, in that they provide valuable information regarding the importance of investigating the various facets of ToM ability separately, in order to provide a more detailed profile of ToM functioning in the clinical samples. © 2013 The British Psychological Society.

    Transarterial radioembolization using Y microspheres is a novel therapeutic option for inoperable hepatic malignancies. As these spheres are radiolucent, real-time assessment of their distribution during the infusion process under fluoroscopic guidance is not possible. Bremsstrahlung radiations arising from 90Y have conventionally been used for imaging its biodistribution. Recent studies have proved that sources of 90Y also emit positrons, which can further be used for PET/computed tomography (CT) imaging. This study aimed to assess the feasibility of 90Y PET/CT imaging in evaluating microsphere distributions and to compare its findings with those of Bremsstrahlung imaging. Thirty-five sessions of 90Y microsphere transarterial radioembolization were performed on 30 patients with hepatic malignancies. 90Y PET/CT imaging was performed within 3 h of therapy. Bremsstrahlung imaging was also performed for each patient. The imaging findings were compared for concordance in the distribution of microspheres. Exact one-to-one correspondence between 90Y PET/CT imaging and 90Y Bremsstrahlung imaging was observed in 97.14% of cases (i.e. in 34/35 cases). Discordance was observed only in one case in which 90Y PET/CT imaging resolved the microsphere uptake in the inferior vena cava tumor thrombus, which was, however, not visualized on Bremsstrahlung imaging. There is good concordance in the imaging findings of 90Y PET/CT and 90Y Bremsstrahlung imaging. 90Y PET/CT imaging scores over the conventionally used Bremsstrahlung imaging in terms of better resolution, ease of technique, and comparable image acquisition time.

    Prison medical workers (PMWs) are critically important, but they are also vulnerable to psychological problems. Currently, there is no study on examining PMWs' mental health conditions and possible influencing factors in China. Hence, we conducted this cross-sectional survey, aiming to understand the mental health status of the PMWs and related impact factors in Jiangxi province of China. We employed the Chinese version of the Symptom Checklist-90-R (SCL-90-R) to assess the mental disorders and psychological health conditions of PMWs in Jiangxi. The t tests were used to compare the differences for the average score of SCL-90-R between the Chinese general population and targeted PMWs of this study. Multivariable logistic regression analyses were conducted to identify the main factors associated with overall detection rate of PMWs' psychological health conditions. The scores of four dimensions (somatization, obsessive-compulsive symptoms, anxiety, and paranoid ideation) were significantly higher than the Chinese national norm, and the total positive rate was 49.09% among the PMWs. Gender, marital status, age, and length of employment are identified to be the most significant predictors to affect PMWs' mental health. Positive correlations between each of the nine dimensions of the SCL-90-R have been verified. This study demonstrated for the first time that PMWs are facing mental health risk and suffering serious psychological problems with psychopathology symptoms, which has become a growing concern in China. Our current findings suggest a need for more in-depth studies on this subject going forward to validate our conclusions and also to identify more impact factors, since such studies and knowledge of PMWs' mental health and influencing factors are very limited in China.

    Background Severe alcoholism can be associated with significant nutritional and vitamin deficiency, especially vitamin B1 (thiamine) which is associated with serious illness and neurological deficits that influence mood and cognition. We previously reported reduced alcohol consumption among female but not male alcoholics after supplementation with the high potency thiamine analog benfotiamine (BF). As a follow-up, we have examined the relationship between lifetime alcoholism severity and psychiatric symptoms among the alcohol dependent men from this cohort and their response to BF treatment. Methods Eighty-five adult men (mean age = 48 ± 8 yrs) meeting DSM-IV-TR criteria for current alcohol dependence participated in a randomized, double-blind, placebo-controlled trial of 600 mg BF vs placebo (PL) for 6 months. Psychometric testing included a derived Lifetime Alcoholism Severity Score (AS), Symptom Checklist 90R (SCL-90R), and the Barratt Impulsivity Scale (BIS) at baseline and at 6 months with data analyzed using ANOVA and MANOVA modeling. Results Baseline SCL-90-R scale scores for men with high alcoholism severity (AS ≥ 24; N=46 HAS) were significantly greater than for men with low alcoholism severity (AS < 24; N=39 LAS), but BIS scores did not differ. MANOVA modeling identified a significant treatment effect (F=2.5, df=10, p<0.03) and treatment x alcoholism severity level interaction (F=2.5, dfnum=10, dfden=30, p<0.03) with SCL-90-R scores showing a reduction in symptoms among BF treated, high severity males. Conclustion BF appears to reduce psychiatric distress and may facilitate recovery in severely affected males with lifetime alcohol dependence and should be considered for adjuvant therapy in alcohol rehabilitation.

    The objective of this study was to investigate the clinical features of depression in Asian patients. It was a cross-sectional, observational study of depression in China, Korea, Malaysia, Singapore, Taiwan, and Thailand. Participants were drug-free outpatients with depressed mood and/or anhedonia. Symptoms and clinical features were assessed using the Montgomery-Asberg Depression Rating Scale, Symptoms Checklist 90-Revised (SCL-90-R), and the Fatigue Severity Scale. Other measures included the Medical Outcome Survey 36-Item Short-Form Health Survey (SF-36), the Sheehan Disability Scale, and the Multidimensional Scale of Perceived Social Support (MSPSS). A total of 547 outpatients with major depressive disorder were included in the analyses. Among the Montgomery-Asberg Depression Rating Scale symptoms, "reported sadness" and "reduced sleep" had the highest severity, with means (SDs) of 3.4 (1.2) and 3.4 (1.6), respectively. Apart from the SCL-90-R depression and anxiety domains, the SCL-90-R obsession-compulsion syndrome had the highest domain score, with a mean (SD) of 1.9 (0.9). Among eight domains, the mean (SD) SF-36 pain subscale score of 58.4 (27.7) was only second to that for the SF-36 physical function. In comparison to other disability domains, the Sheehan Disability Scale work/school had the highest subscale score, with a mean (SD) of 6.5 (2.9). The mean (SD) MSPSS "family" subscale score of 4.7 (1.7) was higher than the MSPSS "friends" and "significant others" subscale scores. This study suggests that pain has a minimal impact on the quality of life in Asian patients with depression. Noteworthy issues in this population may include insomnia, obsessive-compulsive symptoms, working/school disability, and family support. Copyright © 2013 Wiley Publishing Asia Pty Ltd.

    Full Text Available Hsp90 is an abundant protein in mammalian cells. It forms several discrete complexes, each containing distinct groups of co-chaperones that assist protein folding and refolding during stress, protein transport and degradation. It interacts with a variety of proteins that play key roles in breast neoplasia including estrogen receptors, tumor suppressor p53 protein, angiogenesis transcription factor HIF-1alpha, antiapoptotic kinase Akt, Raf-1 MAP kinase and a variety of receptor tyrosine kinases of the erbB family. Elevated Hsp90 expression has been documented in breast ductal carcinomas contributing to the proliferative activity of breast cancer cells; whilst a significantly decreased Hsp90 expression has been shown in infiltrative lobular carcinomas and lobular neoplasia. Hsp90 overexpression has been proposed as a component of a mechanism through which breast cancer cells become resistant to various stress stimuli. Therefore, pharmacological inhibition of HSPs can provide therapeutic opportunities in the field of cancer treatment. 17-allylamino,17-demethoxygeldanamycin is the first Hsp90 inhibitor that has clinically been investigated in phase II trial, yielding promising results in patients with HER2-overexpressing metastatic breast cancer, whilst other Hsp90 inhibitors (retaspimycin HCL, NVP-AUY922, NVP-BEP800, CNF2024/BIIB021, SNX-5422, STA-9090, etc. are currently under evaluation.

    Yttrium-90 is one of the most useful radionuclides for radioimmunotherapeutic applications, especially for labelling peptides and antibodies. Studies were carried out to develop a 90 Sr/ 90 Y generator system based on the SLM technique. Two stages of 90 Sr/ 90 Y generator systems were developed at different activity levels of 5, 20, 50 and 100 mCi and operated with semiautomation in sequential mode. In the first stage of the system, PC88A based SLM was used, which transported 90 Y from a nitric acid medium containing 0.01–4M HNO 3 . In the second stage, the 90 Y from the first stage was transferred to the first compartment of the second stage using carbamoylmethyl phosphine oxide (CMPO) based SLM where 1M acetic acid was used as the receiving phase for 90 Y. Quality control was carried out for the products of 90 Y using EPC with paper chromatography and Tec control chromatography. Peptides and antibodies were labelled using the 90 Y product obtained from the generator developed in house. (author)

    Full Text Available Objective: To investigate whether there were any differences in the quality of life, sexual function, and self-esteem of patients who underwent total laparoscopic hysterectomy (TLH (n=42 and total abdominal hysterectomy (TAH (n=42. Materials and Methods: All premenopausal patients who underwent TLH or TAH because of benign uterine disorders were enrolled. The sexual function and quality of life status were assessed preoperatively and 6 months postoperatively using three standardized validated questionnaires: the Arizona Sexual Experiences Scale (ASEX, the Symptom Checklist-90-Revised (SCL-90-R, and the Rosenberg Self-Esteem Scale (RSES. Results: Preoperative ASEX, SCL-90-R and RSES scores were not different among the hysterectomy subgroups. The postoperative SCL-90-R scores were also not different among the hysterectomy subgroups. The postoperative RSES scores were significantly lower (p<0.05 than the preoperative scores for all procedures (indicating improved self-esteem but did not differ among the groups. The postoperative ASEX scores were significantly decreased (p<0.01 as compared with the preoperative scores (indicating improved sexual function. When the average score of each item of the ASEX score was compared in both groups, significant differences were observed in sexual drive and arousal in the laparoscopy group (p<0.01. Conclusion: Women undergoing TLH for benign uterine disease may have better outcomes related to certain sexual function parameters than women undergoing TAH.

    This part contains a proposal for the generator column design, materials to be used (chemicals, ionexes) and technological procedures. The proposal was inspired by the 90 Sr- 90 Y generator operated by Zfk Rossendorf. The aim was to develop and launch a generator for the preparation of carrier-free 90 Y in the form of [ 90 Y] chloride solution in dilute hydrochloric acid. The separation of Y from Sr is based on ionex chromatography by sorbing the two radionuclides on a catex. While Sr remains sorbed, 90 Y is eluted with lithium citrate. During this process, 90 Y is bonded in a citrate complex which, having a negative charge, is subsequently trapped by an anex. A guard column is inserted before the anex column to trap any traces of 90 Sr. 90 Y is eluted from the anex in the yttrium chloride form by using dilute hydrochloric acid. The product from the generator can be used for the preparation of [ 90 Y] - Fe colloid injection or [ 90 Y] - yttrium citrate injection for intra-articular application or for the development of monoclonal antibodies and peptides

    Maternal psychological stress during pregnancy has essentially been conceptualized as a teratogen. However, little is known about the effect of temperature on maternal stress during pregnancy. The aim of this study is to investigate the relationship between temperature and maternal stress during pregnancy. In 2010, a total of 1931 eligible pregnant women were enrolled across Shanghai from four prenatal-care clinics during their mid-to-late pregnancy. Maternal life-event stress and emotional stress levels during pregnancy were assessed by the "Life Event Scale for Pregnant Women" (LESPW) and "Symptom Checklist-90-Revised Scale" (SCL-90-R), respectively. Exposure to ambient temperature was evaluated based on daily regional average in different moving average and lag days. The generalized estimating equations were used to evaluate the relationship between daily average temperature/temperature difference and maternal stress. After adjusting for relevant confounders, an U-shaped relationship was observed between daily average temperature and maternal Global-Severity-Index (GSI) of the SCL-90-R.

Symptom intensity has a statistical relation with patients' quality of life (QOL and mental health. The first objective of the present study was to develop and provide a therapeutic plan based on cognitive behavioral therapy (CBT for IBS that was operated for the very first time in Iran. The second objective was to determine the effectiveness of these treatments on IBS symptoms intensity, health-related QOL, and psychological health among patients with IBS.Methods: The participants were 15 women with IBS. The participants were diagnosed on the basis of ROME-III diagnosis criteria. The data collection tools consisted of IBS Symptom Severity Scale (IBS-SSS, the Irritable Bowel Syndrome Quality of Life (IBS-QOL questionnaire, and the Symptom Checklist-90-Revised (SCL-90-R used to evaluate mental health. Data were collected during the weeks of 0, 4, 12, and 24, during the treatment process. The extracted data was examined statistically via repeated measures MANOVA in SPSS software.Results: CBT has a significant effect on IBS symptoms reduction, QOL improvement, and mental health promotion of the patients. The effect of the therapeutic plan persisted until the follow-up stage.Conclusion: According to the results, applied CBT can be specifically implemented as an effective treatment for IBS. Therefore, the use of this treatment is advised.

    90 Sr/ 90 Y source trains (Novoste Beta-Cath System) are currently under clinical trials in India and abroad for intracoronary brachytherapy for prevention of restenosis. Each source train of the Beta-Cath system is supplied with a source certificate giving dose rate at the reference distance of 2 mm from the centerline of the source train. It is essential that the user should check dose rates of brachytherapy sources before its application on the patients. Dose rates and depth dose measurements for 90 Sr/ 90 Y source trains of active length 40 mm using radiochromic films in a tissue equivalent phantom have been carried out. The objectives of these measurements were (1) to verify the dose rates stated in the source certificate, and (2) to obtain relative depth dose data for treatment planning. This paper presents the results of these measurements

    UNAIDS' Vision 90:90:90 is a call to 'end AIDS'. Developing predictive foresight of the unpredictable changes that this journey will entail could contribute to the ambition of 'ending AIDS'. There are few opportunities for managing unpredictable changes. We introduce 'weak signal detection' as a potential opportunity to fill this void. Combining futures and complexity theory, we reflect on two pilot case studies that involved the Archetype Extraction technique and the SenseMaker(®) Collector(™) tool. Both the piloted techniques have the potentials to surface weak signals--but there is room for improvement. A management response to a complex weak signal requires pattern management, rather than an exclusive focus on behaviour management. Weak signal detection is a window of opportunity to improve resilience to unpredictable changes in the HIV/AIDS landscape that can both reduce the risk that emerges from the changes and increase the visibility of opportunities to exploit the unpredictable changes that could contribute to 'ending AIDS'.

    90Sr (T1/2 = 28.5 years) is a long-lived radionuclide produced in nuclear fission. Fast radiochemical detection of 90Sr in environmental samples is not feasible using current analytical methods. Accelerator Mass Spectrometry (AMS) measurements of 90Sr were made with the Rehovot 14UD Pelletron accelerator at a terminal voltage of 11 or 12 MV using our standard detection system. Injection of hydride ions (SrH3-) was chosen owing to high beam intensity and low Coulomb explosion effects. 90Sr ions were identified and discriminated from isobaric 90Zr by measuring time of flight, total energy and three independent energy-loss signals in an ionization chamber. A reference sample and a ground-water sample were successfully measured. The detection limit determined for a laboratory blank by the residual counts in the 90Sr region is 90Sr/Sr = 3 ?? 10-13, corresponding in practice to (2-4) ?? 10790Sr atoms or about 0.5-1 pCi/L in environmental water samples.

    To compare measures of psychological distress between men and women undergoing ART in the Unit of Reproductive Medicine "UMR" in the Department of Obstetrics and Gynecology at "Farhat Hached" Hospital in Sousse, Tunisia. We conducted a gender comparative study of psychological profile in infertile couples. Recruitment was done during period from January to May 2009. 100 infertile couples with primary infertility were recruited. Scores of general psychopathology, depression, anxiety and self-esteem were evaluated. We administrated questionnaires on psychological factors among infertile couples before starting a new infertility treatment cycle. Psychological factors included the symptom check-list (SCL-90-R), the hospital anxiety and depression scale (HAD-S) and the Rosenberg self-esteem scale (RSE). Infertile women had higher scores than their spouses in the three global scores of the SCL-90-R and in several items such as somatisation, obsessive symptoms, interpersonal sensitivity and phobias. Scores of HADS were higher among women for both depression and anxiety. Scores of self-esteem were lower among women. Women endorsed higher psychological distress than men across multiple symptoms domains: general psychopathology, anxiety, depression and self esteem. Copyright © 2012 Elsevier Ireland Ltd.

    Although Axis I hypochondriasis is closely related to certain personality characteristics, the nature and extent of personality dysfunction in these patients still needs clarification. This study assessed the prevalence of personality disorders observed in hypochondriacal patients, described the types and comorbidity of personality disorders, and compared the psychological distress of patients with and without the most common comorbid personality disorder. One hundred fifteen patients meeting Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, criteria for hypochondriasis completed self-administered assessments, including the Personality Diagnostic Questionnaire-4+ (PDQ-4+), the Hopkins Symptom Checklist-90-Revised (SCL-90-R), the Whiteley Index, and the Somatic Symptom Inventory. These data were taken from a study conducted between September 1997 and November 2001. Eighty-eight patients (76.5%) had 1 or more personality disorders, whereas 27 patients (23.5%) had no personality disorders. Fifty-one patients (44.3%) had more than 3 personality disorders. The most common personality disorder in the hypochondriacal patients was obsessive-compulsive personality disorder (OCPD; 55.7%), followed by avoidant personality disorder (40.9%). The comorbidity of OCPD and avoidant personality disorder was 53.1% (34 of 64 patients with OCPD). The total PDQ-4+ score of the 64 patients with OCPD was significantly higher than that of the 51 patients without OCPD. On the SCL-90-R, the 64 patients with OCPD showed significantly higher scores on all of 3 global indices and 7 of 10 primary symptom dimensions (paranoid ideation, depression, anxiety, phobic anxiety, obsessive-compulsive, interpersonal sensitivity, and psychoticism) on the SCL-90-R compared to the 51 patients without OCPD. The high prevalence of personality disorders, particularly OCPD, among patients with hypochondriasis suggests that consideration of personality features is important in assessment and

    Borderline personality disorder (BPD) is a significant psychiatric illness for which medication treatments are still being explored. The goal of this study was to assess divalproex extended release (ER) vs placebo for patients receiving dialectal behavior therapy (DBT). Patients with BPD received 4 weeks of "condensed DBT." Those with Symptom Checklist-90 (SCL-90) scores >150 after this treatment were then randomly and blindly assigned to placebo or divalproex ER for 12 weeks. Repeated measures analysis of variance utilizing last observation carried forward was used to assess the results. Seventeen participants completed the full assessment. Two patients had a significant decrease in SCL-90 in the first 4 weeks, leaving 15 patients for the medication phase of the trial. There were no significant differences between the participants assigned to divalproex ER compared with placebo. However, there was a significant improvement in both groups from baseline to endpoint (P = .001). The response of 2 of 17 participants in the first 4 weeks prior to medication may point to a practice strategy in approaching outpatients with BPD. Although the patients had a decrease in symptoms during the study, there was no advantage observed for divalproex ER and DBT over placebo and DBT.

In this study, the activation of early warning system was evaluated under the monitoring of disasters workgroup of the Ministry of Health based on the national program of “hospitals preparedness in disasters” in Shahid Motahari Hospital.  Materials and Methods: The sample was composed of 801 adults exposed to the earthquake. Two months after the earthquake, all subjects were surveyed with measures administrated in a standard order as follows: demographic data sheet, disaster experiences scale (DES, general health questionnaire (GHQ, and symptom checklist 90-revised (SCL-90-R. Results: The results revealed that 23% of the survivors in the exposed group had ASD, 10% had anxiety symptoms, 7.5% depression, 4% MADD, 5% psychosomatic disorders, 10% phobia, 7% aggressive behavior, and 10% insomnia. Conclusion: This article has summarized the current status of information on mental disorders caused by experiencing or witnessing a life threatening severe earthquake. The experience of fear, helplessness, and panic during the earthquake, and the appraisal by the victims of serious psychological, social, as well as demographical consequences after the earthquake, were positively related to the subscale scores and the total score of GHQ, SCL-90-R, and DES.

Among them, the most frequent was proctalgia fugax (7.9%, followed by cyclic vomiting syndrome (6.3%, functional fecal incontinence (6.3%, functional dyspepsia (4.8% and belching (4.8%. The UFBD group scored significantly higher than the control group in the global severity index (GSI and in all SCL-90 subscales (P0.05. Conclusion Pathogenesis of UFBD may be closely correlated with psychiatric and psychological factors and sleep disturbance. cFGID are associated with an increased severity of psychopathological features.

    Full Text Available Hsp90 is one of the most conserved and abundant molecular chaperones and is an essential component of the protective stress response; however, its roles in abiotic stress responses in soybean (Glycine max remain obscure. Here, 12 GmHsp90 genes from soybean were identified and found to be expressed and to function differentially under abiotic stresses. The 12 GmHsp90 genes were isolated and named GmHsp90A1-GmHsp90A6, GmHsp90B1, GmHsp90B2, GmHsp90C1.1, GmHsp90C1.2, GmHsp90C2.1 and GmHsp90C2.2 based on their characteristics and high homology to other Hsp90s according to a new nomenclature system. Quantitative real-time PCR expression data revealed that all the genes exhibited higher transcript levels in leaves and could be strongly induced under heat, osmotic and salt stress but not cold stress. Overexpression of five typical genes (GmHsp90A2, GmHsp90A4, GmHsp90B1, GmHsp90C1.1 and GmHsp90C2.1 in Arabidopsis thaliana provided useful evidences that GmHsp90 genes can decrease damage of abiotic stresses. In addition, an abnormal accumulation of proline was detected in some transgenic Arabidopsis plants suggested overexpressing GmHsp90s may affect the synthesis and response system of proline. Our work represents a systematic determination of soybean genes encoding Hsp90s, and provides useful evidence that GmHsp90 genes function differently in response to abiotic stresses and may affect the synthesis and response system of proline.

    90 Sr+ 90 Y applicators are commonly utilized in brachytherapy, including ophthalmic procedures. The recommended instruments for the calibration of these applicators are extrapolation chambers, which are ionization chambers that allow the variation of their sensitive volume. Using the extrapolation method, the absorbed dose rate at the applicator surface can be determined. The aim of the present work was to develop a mini-extrapolation chamber for the calibration of 90 Sr+ 90 Y beta ray applicators. The developed mini-chamber has a 3.0 cm outer diameter and is 11.3 cm in length. An aluminized polyester foil is used as the entrance window while the collecting electrode is made of graphited polymethylmethacrylate. This mini-chamber was tested in 90 Sr+ 90 Y radiation beams from a beta particle check source and with a plane ophthalmic applicator, showing adequate results

    90Sr is one of the main long-lived fission products, and it is transferred into human body primarily by food, with milk being a substantial contributor. Due to its biochemical similarity to calcium, most strontium is efficiently incorporated into bone tissues. 90Sr is characterized by a long physical half life (28.8 y) and decays by beta particles with an Emax of 0.546 MeV to 90Y. This daughter isotope has a half life of 64 h and decays into 90Zr by beta particles with an Emax of 2.284 MeV. The milk components produce a high turbidity and light attenuation, causing a significant decrease of the counting efficiency in liquid scintillation counting (LSC) systems, mostly used for beta emitters detection. Most methods proposed in the past are time-consuming, as they are based on several stages of chemical and physical treatments, including precipitation, ashing, ion exchange and extraction (Wikins et al., 1984, Porter et al, 1961, Kimura et al., 1979). When measuring 90Sr/90Y activity by Cherenkov counting, most of the Cherenkov radiation is produced by 90Y (about 98.6%), due to the much higher energy of its beta particles relative to these from 90Sr. The counting efficiency varies strongly with color quenching, at a greater extent than in standard liquid scintillation counting (L'Annunziata, 2012), and therefore the quench correction is critical. The ‘‘external source area ratio’’ (ESAR) quench correction method was applied to measure 90Sr/90Y activities in aqueous samples with a wide range of quenching levels (Tsroya et al., 2009). This method was proved to be superior to all other quench correction methods (Tsroya et al., 2012) and is applicable also for determination of 90Sr/90Y in human urine (Tsroya et al., 2013). In the present work the applicability of the ESAR method to measurement of 90Sr/90Y activities in milk and some of its products was investigated

    Full Text Available Background: Several studies have shown a connection between mothers with post-natal depression (PND and emotional-behavioral problems in their children. Mothers' psychopathology may impair interactional patterns with children and these outcomes can be influenced by father's psychopathological symptoms. The primary aim of the study was to assess over time parent-infant interaction in families where mothers have experienced postnatal depression and have received psychological treatment during the child's first year of life considering the severity of parents' psychopathological symptoms and children's temperament. Methods: Three groups of families were involved: families with mothers with PND wherein both parents followed a psychological treatment (TxMF; families with mothers affected by PND wherein only the mother followed the treatment (TxM and control families wherein the mothers did not have a psychopathological diagnosis and did not receive any treatment (Con. The families were assessed at two time points through Symptom Check-List-90-Revised (SCL-90-R, Questionari Italiani Temperamento (QUIT and the video-recorded procedure observing mealtime Scala di Valutazione Interazioni Alimentari (SVIA. Results: Parents in the TxMF group had significantly lower SVIA scores (i.e . less maladaptive at T2. TxMF group scored lower at T2 at SCL-90-R, whereas TxM showed no significant differences between T1 and T2. Involvement of fathers in the treatment was important to improve the psychopathological symptoms of both parents and the quality of interactions with their children.

    Selective mutism (SM) is classified in DSM-5 as an anxiety disorder. The aim of the study was to investigate the psychological features of children with SM and their parental psychological profiles, compared to generalized anxiety disorder (GAD) children and their parents. The parents of 26 preschool children with SM and 32 with children with GAD filled out the child behavior check list for 1½-5 years (CBCL1½-5) and the symptom checklist-90-revised (SCL-90-R). Information about the children and their parents' histories was collected through clinical interviews. Children with SM scored higher than children with GAD on the CBCL1½-5 withdrawn scale and lower on the attention problems, aggressive behavior, and externalizing problems scales. Mothers of children with SM scored higher on the SCL-90-R obsessive-compulsive subscale and Global Severity Index than mothers of children with GAD, while fathers of children with SM scored higher on the SCL-90-R Phobic Anxiety subscale and on the Global Severity Index than fathers of children with GAD. Parents of children with SM displayed a greater presence of stressful life events than parents of children with GAD. Data appeared to confirm that SM and GAD share a common anxious core, though some differences in the children's psychological profiles and the parents' history and personality emerged. Future research should focus on the role of external factors, such as parent-child relationship, in the development of SM.

    Global health organizations frequently set disease-specific targets with the goal of eliciting adoption at the national-level; consideration of the influence of target setting on national policies, programme and health budgets is of benefit to those setting targets and those intended to respond. In 2014, the Joint United Nations Programme on HIV/AIDS set 'ambitious' treatment targets for country adoption: 90% of HIV-positive persons should know their status; 90% of those on treatment; 90% of those achieving viral suppression. Using case studies from Ghana and Uganda, we explore how the target and its associated policy content have been adopted at the national level. That is whether adoption is in rhetoric only or supported by programme, policy or budgetary changes. We review 23 (14 from Ghana, 9 from Uganda) national policy, operational and strategic documents for the HIV response and assess commitments to '90-90-90'. In-person semi-structured interviews were conducted with purposively sampled key informants (17 in Ghana, 20 in Uganda) involved in programme-planning and resource allocation within HIV to gain insight into factors facilitating adoption of 90-90-90. Interviews were transcribed and analysed thematically, inductively and deductively, guided by pre-existing policy theories, including Dolowitz and Marsh's policy transfer framework to describe features of the transfer and the Global Health Advocacy and Policy Project framework to explain observations. Regardless of notable resource constraints, transfer of the 90-90-90 targets was evident beyond rhetoric with substantial shifts in policy and programme activities. In both countries, there was evidence of attempts to minimize resource constraints by seeking programme efficiencies, prioritization of programme activities and devising domestic financing mechanisms; however, significant resource gaps persist. An effective health network, comprised of global and local actors, mediated the adoption and adaptation

    Full Text Available Radiopharmaceuticals based on 90Y are widely used in the treatment of malignant deseases. In order to meet the requirements for their future application, a 90Sr/90Y generator was developed and 90Y eluted from this locally produced generator was used for the radiolabelling of the DOTA-conjugated somatostatin analog [DOTA0,Tyr3] octreotate and the preparation of [90Y-DOTA0,Tyr3] octreotate (90Y-DOTATATE for peptide receptore radionuclide therapy. 90Sr/90Y generator was based on the electrochemical separation of 90Y from 90Sr in a two-cycle electrolysis procedure. Three electrode cells were used to perform both electrolyses. In both cycles, working electrodes were kept on constant potential. The pH of the solution was adjusted to 2.7 of the value before the electrolyses. The radionuclidic purity of the 90Y solution was analysed by ITLC and extraction paper chromatography. The labelling of peptide (100 mg DOTATATE with 90YCl3 was performed at 95°C for 30 minutes. Radiochemical purity was determined by HPLC and chromatographic separation, using a solid SepPak C-18 column. Results obtained confirmed the efficiency of our electrochemical separation technique and quality control methods for 90Y. The achieved efficiency of the 90Sr/90Y generator above 96% of the theoretical value represents a good basis for the further development of this generator. The labelling of the DOTATATE with 90Y exhibited a high efficiency, too: there was less than 1% of 90Y3+in the 90Y-DOTATATE.

    To explore the impacts on physical and mental health of the patients with polycystic ovary syndrome (PCOS) treated with electroacupuncture (EA) or Diane 35. Seventy-two patients of PCOS were randomized into an acupuncture group and a western medication group, 36 cases in each group. In the acupuncture group, acupuncture was applied to relieving liver stagnation and regulating qi activity at Ganshu (BL 18), Danzhong (CV 17), Qimen (LR 14), Zhongwan (CV 4), Tianshu (ST 25), Guanyuan (CV 4), Zigong (EX-CA 1), Sanyinjiao (SP 6), Zusanli (ST 36) and Taichong (LR 3). After qi arrival, the electric stimulation was added for 30 min. Acupuncture treatment was given 3 times a week. In the western medication group, Diane 35 was taken since the 5th day of menstruation and lasted for 21 days. The cycle of treatment was 3 months in the two groups. Before treatment and at the end of treatment, the symptom scores were evaluated and the self-report symptom inventory, symptom checklist-90 (SCL-90) was used for the mental health evaluation and the comparison was made between the two groups. Compared with those before treatment in the same group, the symptom scores were reduced significantly after treatment in the two groups (both P medication group (all P <0.05). EA with relieving liver stagnation and regulating qi activity reduces the symptom scores of PCOS and SCL-90 scores, acting on regulating both physical and mental conditions. The effects achieved with acupuncture are better than those with Diane 35.

    Psychological distress and suicidal behavior are important mental health problems among university students and warrant research to inform strategies for effective prevention in this young population. The present study aimed to assess psychological distress and suicidal behavior and to unravel their associations among university students. A total of 5972 undergraduate students, randomly selected from six universities in central China, comprised the sample. The Chinese version of the Symptom Checklist-90-revised (SCL-90-R) was used to assess various psychological symptoms. Logistic regression analysis was used to examine the relationship between psychological distress and risk for suicidal behavior. 40.7% of the university students reported positive in a least one of the 9 psychological symptom dimensions assessed by the SCL-90-R. 7.6% of the students reported suicidal behavior in the previous twelve months. The risk of suicidal behavior was significantly associated with psychological symptoms of all types, but there were notable differences by sex. For male students, depression and phobic anxiety increased the risk of suicidal behavior. Meanwhile, depression and obsessive-compulsiveness were positively associated with suicidal behavior in female students. Furthermore, increasing risk of suicidal behavior was associated with increasing positive symptom total (PST) score and a statistically significant trend was observed. Data collected from a cross-sectional survey does not allow any examination of causal inference. Psychological distress and suicidal behavior were both common among university students; and psychological distress was highly associated with suicidal behavior. The findings underscore the importance of mental health care for university students. Copyright © 2017 Elsevier B.V. All rights reserved.

    In order to replace the conventional method using violent fuming nitric acid, a new method for the determination of 90 Sr in milk has been developed by using the solvent extraction with bis (2-ethylhexyl) phosphoric acid (HDEHP). The daughter nuclide 90 Y in a radiochemical equilibrium with its parent 90 Sr was extracted with 2:1 HDEHP-toluene from the acid solution (1M HCl) of milk ash sample prepared by dry-ashing. After stripping with 8M HCl, 90 Y, together with stable yttrium added as carrier, was precipitated as oxalate to prepare β-counting source. The radiochemical purity was confirmed by decay curve. The decontamination of strontium was checked by applying non-dispersive fluorescence x-ray analysis using 133 Ba as irradiating source. Bone samples of cow were also analyzed by the same method and the results were compared with those obtained by other methods. The duplicate crosschecking analyses of finely ground bone samples were carried out to examine the effectiveness of this method. This simple new method was found to be very effective for the routine analysis of 90 Sr in these samples. (auth.)

  20. BWR 90 and BWR 90+: Two advanced BWR design generations from ABB

    ABB has two evolutionary advanced light water reactors available today - the BWR 90 boiling water reactor and the System 80+ pressurised water reactor. The BWR 90 is based on the design, construction, commissioning and operation of the BWR 75 plants. The operation experience of the six plants of this advanced design has been very good. The average annual energy availability is above 90%, and total power generation costs have been low. When developing the BWR 90 specific changes were introduced to a reference design, to adapt to technological progress, new safety requirements and to achieve cost savings. The thermal power rating of BWR 90 is 3800 MWth (providing a nominal 1374 MWe net), slightly higher than that of the reference plant ABB Atom has taken advantage of margins gained using a new generation of its SVEA fuel to attain this power rating without major design modifications. The BWR 90 design was completed and offered to the TVO utility in Finland in 1991, as one of the contenders for the fifth Finnish nuclear power plant project. Hence, the design is available today for deployment in new plant projects. Utility views were incorporated through co-operation with the Finnish utility TVO, owner and operator of the two Olkiluoto plants of BWR 75 design. A review against the European Utility Requirement (EUR) set of requirements has been performed, since the design, in 1997, was selected by the EUR Steering Committee to be the first BWR to be evaluated against the EUR documents. The review work was completed in 1998. It will be the subject of an 'EUR Volume 3 Subset for BWR 90' document. ABB is continuing its BWR development work with an 'evolutionary' design called BWR 90+, which aims at developing the BWR as a competitive option for the anticipated revival of the market for new nuclear plants beyond the turn of the century, as well as feeding ideas and inputs to the continuous modernisation efforts at operating plants. The development is performed by ABB Atom

In addition, concern has been raised about the mental health of wives of MSM. In this cross-sectional study, the authors examine the mental health status of a sample of 135 of these women. Participants completed an Internet-administered questionnaire in Xi'an from April to June, 2012. Most were unaware at the time of marriage that their husbands were MSM. Physical abuse was frequently reported; depressive symptom and mental health (Symptom Checklist, SCL-90) scores were significantly higher than those of the general Chinese adult female population. A majority (59.8%) of women reported suicidal thoughts after discovering their husbands' MSM behavior; about 10% had attempted suicide. Multiple logistic regression revealed that women's experience with anal sex was associated with 7.8 times (95% CI: 1.3-65.9) greater odds of suicidal ideation. Also, women who demonstrated mental symptoms on the SCL-90 had 2.3 times (95% CI: 1.04-5.2) the odds of suicidal ideation. These results suggest that wives of MSM have a significant need for mental health care, suicide prevention, HIV education, and social support.

    The Hsp90 chaperone protein regulates the folding, maturation and stability of a wide variety of oncoproteins. In recent years, many Hsp90 inhibitors have entered into the clinical trials while all of them target ATPase showing similar binding capacity and kinds of side-effects so that none have reached to the market. During the regulation progress, numerous protein- protein interactions (PPI) such as Hsp90 and client proteins or cochaperones are involved. With the Hsp90-cochaperones PPI networks being more and more clear, many cancerous proteins have been reported to be tightly correlated to Hsp90-cochaperones PPI. Among them, Hsp90-Cdc37 PPI has been widely reported to associate with numerous protein kinases, making it a novel target for the treatment of cancers. In this paper, we briefly review the strategies and modulators targeting Hsp90-Cdc37 complex including direct and indirect regulation mechanism. Through these discussions we expect to present inspirations for new insights into an alternative way to inhibit Hsp90 chaperone function.

  5. Intracellular dynamics of the Hsp90 co-chaperone p23 is dictated by Hsp90

    p23 is a component of the Hsp90 molecular chaperone machine. It binds and stabilizes the ATP-bound dimeric form of Hsp90. Since Hsp90 binds protein substrates in the ATP conformation, p23 has been proposed to stabilize Hsp90-substrate complexes. In addition, p23 can also function as a molecular chaperone by itself and even possesses an unrelated enzymatic activity. Whether it fulfills the latter functions in cells while bound to Hsp90 remains unknown and is difficult to extrapolate from cell-free biochemical experiments. Using the 'fluorescence recovery after photobleaching' (FRAP) technology, I have examined the dynamics of human p23, expressed as a fusion protein with the green fluorescent protein (GFP), in living human HeLa cells. GFP-p23 is distributed throughout the cell, and its mobility is identical in the cytoplasm and in the nucleus. When the Hsp90 interaction is disrupted either with the Hsp90 inhibitor geldanamycin or by introduction of point mutations into p23, the mobility of p23 is greatly accelerated. Under these conditions, its intracellular movement may be diffusion-controlled. In contrast, when wild-type p23 is able to bind Hsp90, a more complex FRAP behavior is observed, suggesting that it is quantitatively bound in Hsp90 complexes undergoing a multitude of other interactions

The influence of COPD patients’ and their spouses’ psychopathology on patient health-related quality of life was also examined. The following measurements were employed: Forced expiratory volume in 1 second expressed in percentage predicted (FEV1%, Shuttle-Walking-Test (SWT, International Diagnostic Checklists for ICD-10 (IDCL, questionnaires on generic and disease-specific health-related quality of life (St. George’s Respiratory Questionnaire (SGRQ, European Quality of Life Questionnaire (EuroQol, a modified version of a Disability-Index (CDI, and a screening questionnaire for a broad range of psychological problems and symptoms of psychopathology (Symptom-Checklist-90-R (SCL-90-R. One hundred and forty-three stable COPD outpatients with a severity grade between 2 and 4 (according to the GOLD criteria as well as 105 spouses took part in the study. The prevalence of anxiety and depression diagnoses was increased both in COPD patients and their spouses. In contrast, substance-related disorders were explicitly more frequent in COPD patients. Multiple linear regression analyses indicated that depression (SCL-90-R, walking distance (SWT, somatization (SCL-90-R, male gender, FEV1%, and heart disease were independent predictors of COPD patients’ health-related quality of life. After including anxiousness of the spouses in the regression, medical variables (FEV1% and heart disease no longer explained disability, thus highlighting the relevance of spouses’ well-being. The results underline the importance of depression

    The objectives of this study were to compare the personality profiles of adolescent males with and without Internet addiction disorder (IAD), and to determine if IAD is associated with specific parental rearing behaviors. A total of 304 subjects (204 IAD positive and 100 IAD negative controls) completed three instruments: Symptom Checklist-90-revision (SCL-90-R), Eysenck Personality Questionnaire Revised (EPQ-R), and Egna Minnen av Barndoms Uppfostran--'My Memories of Upbringing' (EMBU). SCL-90-R profiles of adolescents with IAD revealed comparatively higher mean scores for all of the nine domains, and significantly higher scores for obsessive-compulsive, interpersonal sensitivity, depression, anxiety, hostility, and paranoid ideation; the mean global symptom index of adolescents with IAD was also significantly higher by approximately 10%. EPQ profiles of adolescents with IAD showed that Internet-dependent individuals tended to exhibit a significantly lower degree of extraversion and a significantly higher degree of psychoticism when compared with the control group. EMBU profiles revealed that adolescents with IAD generally rated both maternal and paternal rearing practices as lacking in emotional warmth, being over-involved, rejecting, and punitive (mothers only). The results of this study confirm that IAD often occurs concurrently with mental symptoms and personality traits such as introversion and psychoticism. Adolescents with IAD consistently rated parental rearing behaviors as being over-intrusive, punitive, and lacking in responsiveness. These findings suggest that the influences of parenting style and family function are important factors in the development of Internet dependency.

    The behaviour of 90 Sr and 90 Y has been studied in an adsorption system of sea water-bottom-set beds of the Atlantic ocean (red clay; pelitic silt). It has been shown that strontium is present in the sea water in one form, viz, Sr 2+ . Adsorption of 90 Sr with bottom-set beds follows the ion-exchange mechanism. Yttrium is present in the sea water at least three forms (two absorbable and one non-absorbable). Yttrium-90 adsorption is an irreversible process and only about 10% 90 Y is desorbed by the sea water from red clay and silt

The activity of Her2 has been shown to be modulated by molecular chaperones such as HSP90. We analyzed expression/amplification data for HSP90 and Her2 on 127 primary resected esophageal adenocarcinomas in order to evaluate a possible relationship between these two molecules. HSP90 expression determined by immunohistochemistry was observed in various levels. Thirty nine (39 tumors (30.7% were classified as Her2-positive according to their immunoreactivity and amplification status. There was a significant correlation between HSP90 expression and Her2-status (p = 0.008. This could also be demonstrated by quantitative protein expression analysis with reverse phase protein arrays (r = 0.9; p < 0.001. Her2-status was associated withpT-category (p = 0.041, lymph node metastases (p = 0.049 and tumor differentiation (p = 0.036 with a higher percentage of cases with negative Her2 status in lower tumor stagesA negative Her2-status was also associated with better survival in univariate and multivariate analysis (p = 0.001 and p = 0.014. For HSP90, no associations between clinical and pathological parameters were found. The observed association between HSP90 expression and Her2 suggests a co-regulation of these molecules in at least a subset of esophageal adenocarcinomas. Anti-HSP90 drugs, which recently have been introduced in cancer treatment, may also be an option for these tumors by targeting HSP90 alone or in combination with Her2.

    Studies have been shown that among several methods that have been used for the treatment of keloids the surgical excision followed by the adjuvant radiotherapy presents the lowest relapsed rate of the injury. In this work a comparative dosimetric study has been performed using a 4 MeV electron beam from a Varian Clinac 2100C linear accelerator at the radiotherapy service of the Hospital das Clinicas of UNESP-HC, Botucatu-SP and an Amershan 90 Sr+ 90 Y brachytherapy applicator with 1491 MBq of activity. Percentage depth dose curves from ionization chamber measurements and through Monte Carlo simulation have been obtained and compared. Dose measurements have been obtained using parallel plates ionization chamber (Esradin A12) and extrapolation mini-chamber developed at IPEN. The dose calculations have been obtained using the well-known Monte Carlo radiation transport code MCNP-4C. Maximum dose differences obtained between measured/calculated values for 90 Sr+ 90 Y applicator and for the electron beam were, respectively: 7.8 % and 8.0%. The profiles of the depth and superficial tissue dose distribution produced by the electron beam revealed themselves flatter and more homogeneous than those produced by the 90 Sr+ 90 Y applicator, especially to wider fields, which cannot be obtained with beta therapy applicators because of their geometric limitations. In conclusion this present work has shown that 90 Sr+ 90 Y applicators could be efficient for small and very superficial lesions but in most cases electron beam sources are more adequate especially for large and deeper lesions.

We examined the relationships of measures of psychopathology to outcomes of screening urine tests for cocaine, opiates, and benzodiazepines in a sample of 56 methadone patients. They also completed the Symptom Check List-90-Revised (SCL-90-R. The highest scales in the SCL-90-R profile of our patients were those indicating somatic discomfort, anger, phobic anxiety, paranoid ideation, and also obsessive-compulsive disorder symptoms (scores above the 39th percentile. The only significant correlations between urine tests and SCL-90-R psychopathology were those involving benzodiazepines: patients with urine tests positive for benzodiazepines had lower social self-confidence (r=0.48, were more obsessive-compulsive (r=0.44, reported a higher level of anger (r=0.41, of phobic tendencies (r=40, of anxiety (r=0.39, and of paranoid tendencies (r=0.38, and also reported more frequent psychotic symptoms (r=0.43.

    Jealousy is a heterogenous emotion on a spectrum from normality to psychopathology. The relationship between different jealousy subtypes/dimensions and affective temperaments remain unknown. In addition, few large surveys have investigated the associations between jealousy subtypes and psychopathological dimensions. A Brazilian Portuguese version of the "Questionario della Gelosia" (QUEGE) was developed. We obtained data from an anonymous web-based research platform. Socio-demographic data was obtained and participants answered the QUEGE, the TEMPS-Rio de Janeiro, and the Symptom Checklist-90-Revised (SCL-90-R). 2042 participants (29% men, 71% female, mean age+SD: 28.9±8.8 years), took part in this survey. Confirmatory factor analysis provided a five-factor model for the QUEGE with self-esteem, paranoia, interpersonal sensitivity, fear of being abandoned, and obsessive dimensions. The anxious, irritable, cyclothymic, and depressive temperaments were independently associated with jealousy dimensions, whereas the hyperthymic temperament was associated with lower scores on the self-esteem jealousy dimension (N=2042, PJealousy subtypes were dissimilarly associated with SCL-90R psychopathological dimensions, whereas the 'obsessive' jealousy dimension was not significantly associated with SCL-90R dimension scores. We found no independent influence of gender across any jealousy dimension. A convenience web-based sample was employed. Cross-sectional design precludes the establishment of causal inferences. Our data indicate that a five-factor solution may provide the best-fit model for the QUEGE. Different jealousy subtypes were independently associated with affective temperaments and psychopathological dimensions. These associations reported herein should be confirmed in prospective studies.

    Non-adherence was more frequent in male than in female psychiatric patients. This multi-center study in China examined the gender difference with regard to attitude towards antipsychotic medications and its associations with socio-demographic variables, insight, and psychopathology. Patients' basic socio-demographic and clinical data were collected. Psychopathology and insight were measured with the Symptom Checklist-90 (SCL-90) and the Insight and Treatment Attitudes Questionnaire (ITAQ), respectively. Their attitudes towards antipsychotic medications were assessed by two standardized questions. Nearly 39.6% (109/275) males and 31.1% (70/225) females reported negative attitudes towards antipsychotic medications. Binary logistic regression revealed that in males single marital status (OR=2.9, 95% CI=1.3-6.4), rural residence (OR=0.4, 95% CI=0.2-0.7), longer duration of schizophrenia (OR=1.0, 95% CI=1.0-1.1), knowledge of medication (OR=1.5, 95% CI=1.3-1.6) and the SCL-90 hostility subscale (OR=0.9, 95% CI=0.9-1.0) were contributors to negative attitudes. In female patients, knowledge about medications (OR=1.4, 95% CI=1.3-1.6), the SCL-90 somatization (OR=0.8, 95% CI=0.8-0.9) and anxiety (OR=1.1, 95% CI=1.0-1.2) subscales were contributors to negative attitudes. The study suggested that different psychosocial and clinical factors accounted for the negative attitude towards antipsychotic treatment in male and female patients.

    Maternal stress is associated with impairments in the neurodevelopment of offspring; however, the effects of the timing of exposure to maternal stress on a child's neurodevelopment are unclear. In 2010, we studied 225 mother-child pairs in Shanghai, recruiting mothers in mid-to-late pregnancy and monitoring offspring from birth until 30 months of age. Maternal stress was assessed prenatally (at 28-36 weeks of gestation) and postnatally (at 24-30 months postpartum) using the Symptom-Checklist-90-Revised Scale (SCL-90-R) and Life-Event-Stress Scale to evaluate mothers' emotional stress and life event stress levels, respectively. Children's cognition and temperament were assessed at 24-30 months of age using the Gesell Development Scale and Toddler Temperament Scale, respectively. Multi-variable linear regression models were used to associate prenatal and postnatal stress with child cognitive and temperamental development. Maternal prenatal and postnatal Global Severity Index (GSI) of SCL-90-R were moderately correlated (ICC r=0.30, Ptoddlers' gross motor, fine motor, adaptive and social behavior development independently of postnatal GSI, while the increase in postnatal GSI was associated with changes in multiple temperament dimensions independently of prenatal GSI. The effects of prenatal and postnatal depression scores of SCL-90-R were similar to those of GSI. Relatively small sample size. Compared with postnatal exposure, children's cognitive development may be more susceptible to prenatal exposure to maternal emotional stress, whereas temperamental development may be more affected by postnatal exposure to maternal emotional stress compared with prenatal exposure.

    The objective of this study was to compare efficacy of two meditation protocols for treating patients with obsessive-compulsive disorder (OCD). Patients were randomized to two groups-matched for sex, age, and medication status-and blinded to the comparison protocol. They were told the trial would last for 12 months, unless one protocol proved to be more efficacious. If so, groups would merge, and the group that received the less efficacious treatment would also be afforded 12 months of the more effective one. The study was conducted at Children's Hospital, San Diego, Calif. Patients were selected according to Diagnostic and Statistical Manual of Mental Disorders, Third Edition-Revised (DSM-III-R) criteria and recruited by advertisements and referral. At baseline, Group 1 included 11 adults and 1 adolescent, and Group 2 included 10 adults. Group 1 employed a kundalini yoga meditation protocol and Group 2 employed the Relaxation Response plus Mindfulness Meditation technique. Baseline and 3-month interval testing was conducted using the Yale-Brown Obsessive Compulsive Scale (Y-BOCS), Symptoms Checklist-90-Revised Obsessive Compulsive (SCL-90-R OC) and Global Severity Index (SCL-90-R GSI) scales, Profile of Moods scale (POMS), Perceived Stress Scale (PSS), and Purpose in Life (PIL) test. Seven adults in each group completed 3 months of therapy. At 3 months, Group 1 demonstrated greater improvements (Student's independent groups t-test) on the Y-BOCS, SCL-90-R OC and GSI scales, and POMS, and greater but nonsignificant improvements on the PSS and PIL test. An intent-to-treat analysis (Y-BOCS) for the baseline and 3-month tests showed that only Group 1 improved. Within-group statistics (Student's paired t-tests) showed that Group 1 significantly improved on all six scales, but Group 2 had no improvements. Groups were merged for an additional year using Group 1 techniques. At 15 months, the final group (N=11) improved 71%, 62%, 66%, 74%, 39%, and 23%, respectively, on

    In the course of participating in the IAEA-CRP during the last two years, Vietnam has achieved the goal of setting up a 90 Sr/ 90 Y generator system based on Supported Liquid Membrane (SLM) technique and also radiolabeling of the eluted 90 Y with antibody, peptides and albumin. A two stage SLM based 90 Sr- 90 Y generator was set up in-house to generate carrier-free 90 Y at different activity levels viz. 5, 20, 50 mCi. The generator system was operated in sequential mode in which 2-ethylhexyl 2-ethylhexyl phosphonic acid (PC88A) based SLM was used in the first stage for the transport 90 Y in 4.0 M nitric acid from source phase where 90 Sr- 90 Y equilibrium mixture is placed in nitric acid medium at pH to 1-2. In the second stage, octyl (phenyl)-N,N-diisobutylcarbamoylmethyl phosphine oxide (CMPO) based SLM was used for the transport of 90 Y selectively to 1.0 M acetic acid which is the best medium for radiolebeling. The eluted 90 Y from the generator was tested for the presence of any traces of 90 Sr using the Extraction Paper Chromatography (EPC) and was found suitable for radiolabeling. The generator system could be upgraded to 100 mCi level successfully due to an expert mission from India through IAEA. The 90 Y product obtained from the generator system was used for radiolabeling of antibody and peptides viz. Rituximab, DOTATATE and albumin particles under different experimental conditions. A new chromatography system could be developed for analyzing 90 Y labeled albumin using the TAE buffer as mobile phase in PC and ITLC

    Full Text Available Aim. To investigate the degree of mental strain and chronic stress in a German community sample of students with IBS-like symptoms. Methods and Materials. Following an internet-based survey about stress, this study recruited 176 German university students (23.45±2.48 years; 48.3% males with IBS-like symptoms according to Rome III and 181 students without IBS (23.55±2.82 years; 50.3% males and compared them regarding current mental strain (SCL-90-R and the extend of chronic stress. Beyond this, IBS subtypes, IBS severity, and health care utilization were assessed. Results. Students fulfilling IBS criteria showed significantly elevated values of mental strain and chronic stress. Nearly 40% of the IBS group (versus 20% of the controls reached a clinically relevant value on the SCL-90-R global severity scale. IBS subtypes did not differ in terms of mental distress or chronic stress. Somatization, anxiety, and the chronic stressors “work overload,” “social tension,” and “dissatisfaction with job” were most closely connected to IBS symptom severity. Regarding health care utilization, our results show that consulting a physician frequently was not associated significantly with elevated mental strain or chronic stress but with IBS symptom severity. Conclusion. Our data contribute additional evidence to the distinct association between psychological stress and IBS in community samples.

    Coelho, Talita Salles

    2010-01-01

    The 90 Sr+ 90 Y applicators, used in betatherapy for prevention of keloids and pterigium, are imported and many times their dosimetric features are shown only in an illustrated form by the manufacturers. The exhaustive routine of the medical physicists in the clinic do not make possible the accomplishment of procedures for the confirmation of these parameters. This work presents the development of a methodology for the dosimetry of 90 Sr+ 90 Y betatherapy applicators. The Monte Carlo code MCNP5 was used for the simulation of the percentage depth dose curves and dose distribution profiles produced by these applicators. The experimental measurements of the radial and axial radiation attenuation, have been done with a mini-extrapolation chamber, thermoluminescent dosimeters and radiographic films. The experimental results have been compared with the simulated values. Both percentage depth dose curves and the radial dose profiles, the theoretical and the experimental ones, have presented good agreement, which may validate the use of the MCNP5 for these simulations, confirming the viability of the usage of this method in procedures of beta emitter sources dosimetry.

    90 Sr+ 90 Y clinical applicators are used for brachytherapy in Brazilian clinics even though they are not manufactured anymore. Such sources must be calibrated periodically, and one of the calibration methods in use is ionometry with extrapolation ionization chambers. 90 Sr+ 90 Y clinical applicators were calibrated using an extrapolation minichamber developed at the Calibration Laboratory at IPEN. The obtained results agree satisfactorily with the data provided in calibration certificates of the sources. - Highlights: • 90 Sr+ 90 Y clinical applicators were calibrated using a mini-extrapolation chamber. • An extrapolation curve was obtained for each applicator during its calibration. • The results were compared with those provided by the calibration certificates. • All results of the dermatological applicators presented lower differences than 5%

    90 Y is one of the most useful radionuclides for radioimmunotherapeutic applications and has a half-life (t 1/2 =64.14 h) suitable for most therapeutic applications, beta particles of high energy and decays to a stable daughter. It is significant that 90 Y is available conveniently and inexpensively from a radionuclide 'generator' by decay of its parent, 90 Sr. Nevertheless, current and planned clinical applications with [ 90 Y] labelled compounds employ activity levels that cannot be readily obtained from an in-house generator, but from commercial sources. We have evaluated Eichrom's Sr-resin, either as an 'in-house' generator or as a fast QC method for analysis of 90 Y solutions. In particular, for the development as a generator, we investigated the percentage of the radio-Sr in the first 8 M HNO 3 eluate: in this fraction the concentration of 90 Sr must be smaller than 10 -5 % (recommendations of the International Commission on Radiological Protection). For evaluation as a rapid QC method, we analyzed the concentration of 90 Y in all the fractions containing 'only' radio-Sr: 90 Y should not be present in these eluates. After the collection of β - and γ spectra and analysis of them, we concluded that commercial Sr-resin minicolumn cannot give us the results expected; we developed an in-house system loaded with 4 mL of Sr-resin which gave better results as a generator and a rapid QC method.

    Heat shock protein 90 (Hsp90) is a highly conserved heat shock protein in animal and plants, and exists abundantly in the cytoplasm in unstressed condition, accounting for 1-2% in cytoplasmic proteins. Main difference of Hsp90 from other Hsps are its substrate that Hsp90 binds to. These substrates include various signal transduction proteins, kinase, steroid receptors and transcription factors, therefore, Hsp90 plays a key role in maintaining cellular signal transduction networks. Many chaperoned proteins (client proteins) of Hsp90 are associated with cellular proliferation or malignant transformation, thus Hsp90 chaperone complex has been focused as targets for cancer therapy. Among the client proteins, there are several molecules that have been defined as targets or factors for determination or enhancement of radiosensitivity or thermosensitivity. Thus, it is easily speculated that Hsp90 chaperone complex inhibitors that disrupt association of Hsp90 and client protein in combination with radiation or/and heat has potential effect on enhancement of radiosensitivity or thermosensitivity. In this paper, possible mechanisms in enhancing radiosensitivity or thermosensitivity according to the client proteins will be summarized. (author)

Cognitive behavioral therapy (CBT is known to improve these broad dimensions of psychopathology in addition to PD symptoms. However, little is known about the predictors of treatment response in comorbid psychiatric symptoms after CBT for PD. Recent studies suggest that anxiety sensitivity (AS may be a key vulnerability for PD. This study aimed to examine AS as a predictor of broad dimensions of psychopathology after CBT for PD. Materials and methods: In total, 118 patients with PD were treated with manualized group CBT. We used multiple regression analysis to examine the associations between 3 Anxiety Sensitivity Index (ASI factors (physical concerns, mental incapacitation concerns, and social concerns at baseline and the subscales of the Symptom Checklist-90 Revised (SCL-90-R at endpoint. Results: Low levels of social concerns at baseline predicted low levels on 5 SCL-90-R subscales after CBT: interpersonal sensitivity, depression, hostility, paranoid ideation, and psychosis. High levels of mental incapacitation concerns significantly predicted low levels on 3 SCL-90-R subscales after treatment: interpersonal sensitivity, hostility, and paranoid ideation. Physical concerns at baseline did not predict broad dimensions of psychopathology. Conclusion: This study suggested that the social concerns and mental incapacitation concerns subscales of the ASI at baseline predicted several dimensions of psychopathology after CBT for PD. To improve comorbid psychopathology, it may be useful to

    Objective:To study mental health status and personality of patients with cirrhosis, for examining the role of psychological factors in the genesis and development of the illness.Methods: Mental health status and personality of patients with cirrhosis were assessed by Symptom Checklist-90 (SCL-90)and Eysenck Personality Questionnaire (EPQ). Results: Except for Interpersonal Sensitivity (IS) and Psychosis (P), factor scores of SCL were found to be significantly higher in patients with cirrhosis when compared to controls (P<0.01), especially for Somatization (S), Obsessive-Compulsion (OC), Anxiety (A) and Depression (D). Neuroticism score of EPQ in patients with cirrhosis were also significantly higher than that in controls (P<0.01). Conclusion: Mental health status of patients with cirrhosis was shown to be poor, as characterized by greater emotional distress and poorer regulatory control over environmental stress. The higher Neuroticism score of EPQ indicated higher levels of emotional instability and mental irritability among patients with cirrhosis, which should be addressed by appropriate psychological interventions for better clinical outcomes.

    A recent paper has reviewed methods for the evaluation of discrepant sets of data and demonstrated the results of applying these methods to the published half-life data of 90 Sr and 137 Cs [MacMahon, T.D., Pearce, A., Harris, P., 2004. Convergence of techniques for the evaluation of discrepant data. Appl. Radiat. Isot. 60, 275-281]. The half-life data for 3 H has been subject to a comprehensive review and critical evaluation by Lucas and Unterweger [2000. Comprehensive review and critical evaluation of the half-life of tritium. J. Res. Natl. Inst. Stand. Technol. 105, 541-549]. The current paper reports the results of applying the various evaluation procedures of MacMahon et al. Convergence of techniques for the evaluation of discrepant data. Appl. Radiat. Isot. 60, 275-281] to the data of Lucas and Unterweger [Comprehensive review and critical evaluation of the half-life of tritium. J. Res. Natl. Inst. Stand. Technol. 105, 541-549], resulting in a recommended half-life of 4497(4) days. MacMahon et al. [Convergence of techniques for the evaluation of discrepant data. Appl. Radiat. Isot. 60, 275-281] highlighted problems in the evaluation of the discrepant half-life data of 90 Sr, in particular the worrying upward trend in the data, where the weighted mean of all the measurements increases, on average, by 35 days each time a new measurement result is added. The current paper reports on further analyses of these data. New measurements of the half-life of 90 Y have been reported by Kossert and Schrader [2004. Standardization by liquid scintillation counting and half-life measurements of 90 Y. Appl. Radiat. Isot. 60, 741]. This has prompted a new evaluation of all available published 90 Y half-life data. The data are fairly consistent, and a value of 64.063(16) h is recommended

  2. Spatio-temporal regulation of Hsp90-ligand complex leads to immune activation.

    Full Text Available Hsp90 is the most abundant cytosolic HSP and is known to act as a molecular chaperone. We found that an Hsp90-cancer antigen peptide complex was efficiently cross-presented by human monocyte-derived dendritic cells and induced peptide-specific cytotoxic T lymphocytes. Furthermore, we observed that the internalized Hsp90-peptide complex was strictly sorted to the Rab5+, EEA1+ static early endosome and the Hsp90-chaperoned peptide was processed and bound to MHC class I molecules through a endosome-recycling pathway. We also found that extracellular Hsp90 complexed with CpG-A or self-DNA stimulates production of a large amount of IFN-α from pDCs via static early endosome targeting. Thus, extracellular Hsp90 can target the antigen or nucleic acid to a static early endosome by spatio-temporal regulation. Moreover, we showed that Hsp90 associates with and delivers TLR7/9 from the ER to early endosomes for ligand recognition. Hsp90 inhibitor, geldanamycin derivative inhibited the Hsp90 association with TLR7/9, resulting in inhibition IFN-α production, leading to improvement of SLE symptoms. Interstingly, we observed that serum Hsp90 is clearly increased in patients with active SLE compared with that in patients with inactive disease. Serum Hsp90 detected in SLE patients binds to self-DNA and/or anti-DNA Ab, thus leading to stimulation of pDCs to produce IFN-α. Thus, Hsp90 plays a crucial role in the pathogenesis of SLE and that an Hsp90 inhibitor will therefore provide a new therapeutic approach to SLE and other nucleic acid-related autoimmune diseases. We will discuss how spatio-temporal regulation of Hsp90-ligand complexes within antigen-presenting cells affects the innate immunity and adaptive immunity.

    Idiopathic pulmonary fibrosis (IPF) is a progressive disease of the lung parenchyma, causing significant morbidity through worsening dyspnoea and overall functional decline. IPF is characterised by apoptosis-resistant myofibroblasts, which are a major source for the excessive production of extracellular matrix (ECM) overtaking normal lung tissue. We sought to study the role of heat shock protein (HSP) isoforms HSP90α and HSP90β, whose distinct roles in lung fibrogenesis remain elusive.We determined the level of circulating HSP90α in IPF patients (n=31) and age-matched healthy controls (n=9) by ELISA. The release of HSP90α and HSP90β was evaluated in vitro in primary IPF and control lung fibroblasts and ex vivo after mechanical stretch on fibrotic lung slices from rats receiving adenovector-mediated transforming growth factor-β1.We demonstrate that circulating HSP90α is upregulated in IPF patients in correlation with disease severity. The release of HSP90α is enhanced by the increase in mechanical stress of the fibrotic ECM. This increase in extracellular HSP90α signals through low-density lipoprotein receptor-related protein 1 (LRP1) to promote myofibroblast differentiation and persistence. In parallel, we demonstrate that the intracellular form of HSP90β stabilises LRP1, thus amplifying HSP90α extracellular action.We believe that the specific inhibition of extracellular HSP90α is a promising therapeutic strategy to reduce pro-fibrotic signalling in IPF.

    Full text: A retrospective review of Yttrium 90 synovectomies carried out from June 1997 to February 1999 in Auckland Hospital to determine outcome from the procedure. Methods: Patients were sent a questionnaire for each treated knee The principal outcome measures assessed in the month prior and the 6 months after the Y90 were pain, swelling, walking distance and overall disability score. Referring doctors were sent a questionnaire to provide information on duration of synovitis and treatment. Outcomes measured were presence of effusion 6 months after the Y90, requirement for intra-articular steroid in the 12 months prior to and after the yttrium and change of therapy due lo ongoing symptoms in the treated knee. Results: 29 patients and 40 knees had Y90 during the study period 86% patients with 87.5% knees responded. Referring doctors for 86% patients accounting for 87.5% knees responded. The procedure was well tolerated with the majority of patients reporting nil-mild discomfort during and in the 24 hours after Y90. 86% knees treated reported improvement with a reduction in pain and swelling Patient global assessment reduced from 3.8 to 2.0 while physician global assessment reduced from 3.9 to 3.0. There was an improvement in walking distance 6 months after Y90 with the number of knees able to walk >1km increasing from 2 to 17 14 of 25 patients required a change in treatment because of ongoing problems in the treated knee and one patient has undergone knee joint replacement One further patient is waiting knee joint replacement The need for intra-articular steroid was reduced with 83%, knees having an average of 2.4 steroid injections in the 12 months prior to Y90 compared to 38% knees having an average of 0.7 steroid injections in the 12 months after Y90. Of the 30 knees reporting Improvement 24 knees are at least 12 months post Y90. Of these 50% were Improved at 12 months. As a result of this audit we continue to offer this procedure in the Auckland area, and

    Evidence has suggested that cognitive-behavioral therapy (CBT) is effective in reducing hypochondriacal symptoms, and another line of evidence has suggested that CBT is also effective in reducing pain and the psychological conditions associated with chronic low-back pain (CLBP). The purpose of this study was to examine the effectiveness of CBT among hypochondriacal patients with and without CLBP. A total of 182 hypochondriacal patients were randomly assigned to a CBT or control group. The Somatic Symptom Inventory was used to define CLBP, and the Symptom Checklist 90R (SCL90R) was used to assess psychological symptoms. The outcome measures for hypochondriasis, the Whiteley Index (WI) and the Health Anxiety Inventory (HAI) were administered before the intervention and at 6 and 12 months after completion of the intervention. In the total sample, both WI and HAI scores were significantly decreased after treatment in the CBT group compared with the control group. Ninety-three (51%) patients had CLBP; the SCL90R scores for somatization, depression, phobic anxiety, paranoid ideation, and general severity were significantly higher in CLBP(+) group than in the CLBP(-) group at baseline. Although the WI and HAI scores were significantly decreased after treatment in the CLBP(-) group, such significant pre- to post-changes were not found in the CLBP(+) group. CBT was certainly effective among hypochondriacal patients without CLBP, but it appeared to be insufficient for hypochondriacal patients with CLBP. The core psychopathology of hypochondriacal CLBP should be clarified to contribute to the adequate management of hypochondriacal symptoms in CLBP patients.

    To determine the factors closely correlated with the unhealthy psychological status of patients with lung cancer and to ascertain whether the unhealthy psychology adversely affects their quality-of-life (QOL). Methods: Patients newly diagnosed with lung cancer between May 2013 and December 2015 in the Department of Thoracic Surgery, Tianjin 4th Centre Hospital, Tianjin, China were enrolled in this cross-sectional study. Patients were asked to complete the Symptom Checklist 90 (SCL-90) and Quality of Life Questionnaire (QLQ-C30) survey. From the responses, the correlation between the patient's psychological status and QOL were analyzed with respect to several variables. Results: From the total of 258 patients subjected to the test, 168 belonged to the unhealthy psychology group and 90 to the healthy psychology group. Multiple regression analysis revealed that significant factors related to poor QOL among the 2 groups are gender (p=0.02), younger age (p=0.001), surgical history (p=0.04), employment status (p=0.03), and medical insurance (p=0.01) significantly predicted the severity of unhealthy psychology in lung cancer patients. A significantly negative correlation was noted between the points of SCL-90 and the general QOL in all included patients (p=0.03). Conclusion: Gender, younger age, surgical history, employment status, and medical insurance significantly predicted the severity of unhealthy psychology in lung cancer patients.

    In order to replace the conventional method using violent fuming nitric acid, a new method for the determination of /sup 90/Sr in milk has been developed by using the solvent extraction with bis (2-ethylhexyl) phosphoric acid (HDEHP). The daughter nuclide /sup 90/Y in a radiochemical equilibrium with its parent /sup 90/Sr was extracted with 2:1 HDEHP-toluene from the acid solution (1M HCl) of milk ash sample prepared by dry-ashing. After stripping with 8M HCl, /sup 90/Y, together with stable yttrium added as carrier, was precipitated as oxalate to prepare ..beta..-counting source. The radiochemical purity was confirmed by decay curve. The decontamination of strontium was checked by applying non-dispersive fluorescence x-ray analysis using /sup 133/Ba as irradiating source. Bone samples of cow were also analyzed by the same method and the results were compared with those obtained by other methods. The duplicate crosschecking analyses of finely ground bone samples were carried out to examine the effectiveness of this method. This simple new method was found to be very effective for the routine analysis of /sup 90/Sr in these samples.

    Hormonal alterations in Eating Disorders (ED) may result from the biochemical stress of malnutrition/starvation. The correlations between some hormonal impairments, particularly of the somatotropic axis, and the psychopathological aspects of ED are still undefined. We measured the plasma concentrations of the somatotropic hormone (GH) and the insulin-like growth factor-1 (IGF-1) in 136 patients with various forms of ED, 65 with restricted Anorexia Nervosa (ANR), 19 with bingeing-purging Anorexia Nervosa (ANBP), 12 with purging-non binging Anorexia Nervosa (ANP), 26 with Bulimia Nervosa (BN), 8 with ED not otherwise specified-anorexic type (EDNOS-AN), 7 with ED not otherwise specified-bulimic type (EDNOS-BN) and in 30 healthy controls. Psychological assessment of patients and controls was performed using two outpatient rating scales, the Eating Disorder Inventory-2 (EDI-2) and the Symptom Checklist-90 (SCL-90). Significant negative or positive correlations were observed between GH-IGF-1 concentrations and impairments on several EDI-2 subscales (drive for thinness, body dissatisfaction, interoceptive awareness, sense of ineffectiveness, interpersonal distrust, maturity fear) and on SCL-90 subitems (depression, hostility, obsessivity compulsivity, anxiety), suggesting a possible hormonal modulatory effect on specific aspects of ED psychopathology.

    Full Text Available Abstract Background Burnout is a psychosomatic syndrome characterized by three dimensions (emotional exhaustion [EE], feelings of depersonalization [DP], and reduced personal accomplishment [PA]. We determined the prevalence of burnout and mental health status between HIV/AIDS healthcare workers and other healthcare workers, and determined the factors associated with burnout of HIV/AIDS healthcare workers. Methods All participants were asked to complete a self-administered questionnaire. The participants were recruited from the departments of infectious diseases in four hospitals which treated HIV/AIDS. The questionnaire included demographics, the Maslach Burnout Inventory-General Survey (MBI-GS, the Symptom Checklist 90 (SCL-90, the Eysenck Personality Questionnaire (EPQ, and the Trait Coping Style Questionnaire (TCSQ. Results A total of 512 questionnaires were distributed; 501 questionnaires were completed and collected (the response rate was 97.9 %. After eliminating nine invalid questionnaires (1.80 %, 264 physicians and nurses caring for HIV/AIDS and 228 physicians and nurses caring for other infectious diseases provided valid responses (98.2 %. The HIV/AIDS healthcare workers’ scores on the emotional exhaustion (F = 6.350, p = 0.012 and depersonalization dimensions (F = 8.533, p = 0.004 were significantly higher than other healthcare workers. The HIV/AIDS healthcare workers had higher total scores and positive items on the Symptom Checklist 90 (SCL-90 compared with other healthcare workers. Low job satisfaction, serious somatization, interpersonal sensitivity, poor quality of sleep, high psychoticism scores, and use of negative coping styles were frequently associated with burnout. Conclusions Burnout was shown to be highly prevalent in HIV/AIDS healthcare workers, 76.9 % of whom met the accepted criteria for burnout. In addition, compared with other healthcare workers, HIV/AIDS healthcare workers experienced lower

    Pelizza, Lorenzo; Pupo, Simona

    The term "brittle" is used to describe an uncommon subgroup of patients with type I diabetes whose lives are disrupted by severe glycaemic instability with repeated and prolonged hospitalization. Psychosocial problems are the major perceived underlying causes of brittle diabetes. Aim of this study is a systematic psychopathological and personological assessment of patients with brittle diabetes in comparison with subjects without brittle diabetes, using specific parameters of general psychopathology and personality disorders following the multi-axial format of the current DSM-IV-TR (Diagnostic and Statistical manual of Mental Disorders - IV Edition - Text Revised) diagnostic criteria for mental disorders. Patients comprised 42 subjects with brittle diabetes and a case-control group of 42 subjects with stable diabetes, matched for age, gender, years of education, and diabetes duration. General psychopathology and the DSM-IV-TR personality disorders were assessed using the Symptom Checklist-90-Revised (SCL-90-R) and the Structured Clinical Interview for axis II personality Disorders (SCID-II). The comparison for SCL-90-R parameters revealed no differences in all primary symptom dimensions and in the three global distress indices between the two groups. However, patients with brittle diabetes showed higher percentages in borderline, histrionic, and narcissistic personality disorder. In this study, patients with brittle diabetes show no differences in terms of global severity of psychopathological distress and specific symptoms of axis I DSM-IV-TR psychiatric diagnoses in comparison with subjects without brittle diabetes. Differently, individuals with brittle diabetes are more frequently affected by specific DSM-IV-TR cluster B personality disorders. Copyright © 2016 Elsevier Inc. All rights reserved.

    The aim of this study was to analyze the effects of neurofeedback training for reducing stress and enhancing self-regulation in late adolescence to identify the possibility of use for nursing intervention. A nonequivalent control group pre-post quasi-experimental design was used. Participants were 78 late adolescents assigned to the experimental group (n=39) that received the neurofeedback training and the control group (n=39). Data were collected on heart rate variability (HRV) and skin conductance level (SCL) to assess stress-biomarker response. The questionnaire contained 164 items from: Positive and Negative Affect Schedule (PANAS), Symptom Checklist-90-Revised (SCL-90-R) and Self-regulatory Ability scale. The neurofeedback training was based on the general adaptation syndrome and body-mind medicine. The intervention was conducted in a total of 10 sessions for 30 minutes per session with high-beta, theta and sensory motor rhythm training on scalp at central zero. There were significant difference in standard deviation of normal to normal interval (p=.036) in HRV and SCL (p=.029) of stress-biomarker response between the two groups. Negative affect (p=.036) in PANAS and obsessive compulsive (p=.023) and depression (p<.001) in SCL-90-R were statistically significant. Self-regulation mode (p=.004) in self-regulation ability scale showed a significant difference between the two groups. The results indicated that the neurofeedback training is effective in stress-biomarkers, psychoemotional stress response and self-regulation. Therefore, neurofeedback training using neuroscientific approach based on brain-mind-body model can be used as an effective nursing intervention for late adolescents in clinics and communities for effective stress responses. © 2018 Korean Society of Nursing Science.

    One of the most attractive fields for utilization of large quantities of waste fission products is the field of direct-conversion power supplies for remote locations. Strontium-90 is being given the greatest exploitation because of its availability, nuclear properties, and the relative ease with which it can be fabricated into compact heat sources. Strontium-90 fuelled generators are being used to power automatic weather stations and navigational aids, and consideration is being given to the use of strontium-90 as a power source for space vehicles. Evaluation of several potentially useful strontium compounds led to the selection of the titanate as exhibiting overall properties most desirable for this purpose. Strontium-90, separated from crude fission product streams and purified to the requisite degree by the USAEC's Hanford Works, is shipped in the form of the carbonate to a hot cell facility operated by the Martin Company, where it is converted to titanate pellets. This process is an adaption to remote operation of conventional chemical and ceramic techniques. The pellets are encapsulated in Hastelloy C containers for use in thermoelectric power supplies. Unusual operational problems are encountered because the large quantities of strontium-90 handled (potentially millions of curies per year) represent formidable radiation and contamination hazards. Details of the facility, equipment, process, and safety criteria are given. The operational experience gained during the recent processing of the first 250 000 curies of strontium-90 into fuel for a SNAP-7 generator is described. Encapsulation, calorimetry, decontamination, and waste disposal procedures are also outlined.

    Science.gov (United States)

    2018-01-01

    Background To further understand the relationship between anxiety and depression, this study examined the factor structure of the combined items from two validated measures for anxiety and depression. Methods The participants were 406 patients with mixed psychiatric diagnoses including anxiety and depressive disorders from a psychiatric outpatient unit at a university-affiliated medical center. Responses of the Beck Anxiety Inventory (BAI), Beck Depression Inventory (BDI)-II, and Symptom Checklist-90-Revised (SCL-90-R) were analyzed. We conducted an exploratory factor analysis of 42 items from the BAI and BDI-II. Correlational analyses were performed between subscale scores of the SCL-90-R and factors derived from the factor analysis. Scores of individual items of the BAI and BDI-II were also compared between groups of anxiety disorder (n = 185) and depressive disorder (n = 123). Results Exploratory factor analysis revealed the following five factors explaining 56.2% of the total variance: somatic anxiety (factor 1), cognitive depression (factor 2), somatic depression (factor 3), subjective anxiety (factor 4), and autonomic anxiety (factor 5). The depression group had significantly higher scores for 12 items on the BDI while the anxiety group demonstrated higher scores for six items on the BAI. Conclusion Our results suggest that anxiety and depressive symptoms as measured by the BAI and BDI-II can be empirically differentiated and that particularly items of the cognitive domain in depression and those of physical domain in anxiety are noteworthy.

    The work reported in this paper provides a systematic study towards the development of an optimized strategy for preparation of a clinically relevant dose of {sup 90}Y-labeled dimeric RGD peptide derivative, DOTA-E[c(RGDfK)]{sub 2} [DOTA-(RGD){sub 2}] for in vivo targeted therapy utilizing {sup 90}Y obtained from a novel electrochemical {sup 90}Sr/{sup 90}Y generator. The performance of the generator was evaluated to ensure its suitability for providing {sup 90}Y in adequate quantity and purity required for formulation of clinically relevant dose for PRRT. {sup 90}Y-DOTA-(RGD){sub 2} was synthesized in high yield (86.2 ± 2.5%) and radiochemical purity (98.4 ± 0.5%) using clinically relevant dose (∝ 3.8 GBq) of {sup 90}Y. In vitro stability studies revealed that the radiolabeled conjugate retained its radiochemical purity in normal saline and human serum. Preliminary biodistribution studies carried out in C57/BL6 mice bearing melanoma tumors showed that the preparation exhibited significant tumor uptake (5.30 ± 0.78% of injected activity at 30 min post-injection) with good tumor to background ratio. The optimized radiolabeling protocol seems to be an attractive strategy which is largely viewed as a springboard to realize scope of developing {sup 90}Y labeled cyclic RGD peptides for targeted therapy of tumors over-expressing integrin-α{sub ν}β{sub 3} receptors.

    Osteoarthritis (OA) of the hip and knee causes pain and loss of joint mobility, leading to limitations in physical function. When conservative treatment fails total hip and knee replacement is a cost-effective surgical option. Patients have high expectations regarding functional outcome after these procedures. If such expectations are not met, they may still be dissatisfied with the outcome of a technically successful procedure. Recently, numerous studies reported that psychological factors can influence the outcome of total knee replacement (tkr) and total hip artrhoplasty with total hip replacement (thr). We conducted a prospective study on a consecutive sample of 280 patients affected by hip or knee OA who underwent total joint replacement. At patients’ admission, Harris Hip Score (HHS) and Knee Society Score (KSS) were used to assess pain and function. Furthermore, SF-36, Mini-Mental Status Examination (MMSE), Symptom Checklist-90-R (SCL-90-R), Coping Orientation to Problems Experienced (BRIEF-COPE) and the Amsterdam Preoperative Anxiety and Information Scale (APAIS) were administered. Patients had clinical and radio graphical follow up at 1, 3 and 6 months post-operatively. The HHS and KSS values before surgery showed a linear correlation with both SCL-90-R and MMSE. None of the investigated variables influenced post-operative HHS and KSS scores; however, the improvement of functional scores resulted conditioned by SCL-90-R values, VAS score, schooling and MMSE. Psychological factors and mental status in primary total hip and knee replacement can affect outcome and patient satisfaction. Strategies focused on identification and facing of these conditions must be considered to improve outcome of total replacement.

    Full text: Yttrium-90 (Y-90) is a daughter product of strontium-90 (Sr-90). It is specified that there should be less than 2 micro-curie of Sr-90 in Y-90 radiopharmaceuticals. Since both nuclides are beta emitting and there is always a contamination of Y-90 in Sr-90 sample, validation of the analytical method is necessary. In this study, commercial Y-90 and Sr-85 (a gamma emitting isotope of strontium) were used as daughter and mother nuclides, respectively. Extraction paper chromatography technique and its efficient validation method were investigated. Bis-(2-ethylhexyl) diphosphonate was dropped at the origin of chromatography paper and air dried prior to sample drops. Validation of the separation was done by radio-chromatography scanning of the chromatography paper. Their energy spectra were identified in the spectra mode of Packard Cobra II automatic gamma counter, which can differentiate a pure gamma, a pure beta and a mixture of beta and gamma nuclides. Results showed that yttrium acetate remained fixed at the origin of the chromatography paper while strontium acetate moved to the solvent front when developed in saline. In conclusion, the extraction paper chromatography technique can effectively separate Sr-90 from Y-90

    The aim of this study was to determine the validity and reliability of a 90-minute soccer performance test: Ball-sport Endurance and Sprint Test (BEAST90). Fifteen healthy male amateur soccer players participated and attended 5 testing sessions over a 10-day period to perform physiologic and soccer-specific assessments. This included familiarization sessions and 2 full trials of the BEAST90, separated by 7 days. The total 90-minute distance, mean percent peak heart rate (HRpeak), and estimated percent peak oxygen uptake of the BEAST90 were 8,097 ± 458 m, 85 ± 5% and 82 ± 14%, respectively. Measures obtained from trial 1 and trial 2 were not significantly different (p > 0.05). Reliability of measures over 90 minutes ranged from 0.9-25.5% (% typical error). The BEAST90 protocol replicated soccer match play in terms of time, movement patterns, physical demands (volume and intensity), distances, and mean and HRpeak values, as well as having an aerobic load similar to that observed during a soccer match. Reproducibility of key physical measures during the BEAST90 were mostly high, suggesting good reliability. The BEAST90 could be used in studies that wish to determine the effects of training or nutritional interventions on prolonged intermittent physical performance.

    Kulikov, N.V.; Ozhegov, L.N.

    1976-01-01

    The results are given of laboratory experiments aimed at studying accumulation of Sr-90 and its daughter product Y-90 in the spawn and larvae of whitefish, a representative of autumn spawning fish species. The results are of interest for predicting possible consequences of radioactive contamination of water bodies and introduction of limits for permissible concentration of radioactive substances in aqueous medium. The accumulation coefficient of Sr-90 in the spawn reaches its maximum after the first twenty four hours of the experiment. Subsequently throughout the incubation period the accumulation coefficient (AC) of radionuclide does not undergo any changes being about 3. Besides it has been established that the equilibrium distribution of Sr-90 in whitefish spawn and the surrounding solution occurs during the first two hours. Unlike Sr-90 the accumulation of Y-90 occurs during the whole incubation period and results in the AC value of 80 by the end of the spawn incubation. The experiments aimed at determining the strength of radionuclide fixation by whitefish spawn and larvae revealed that both radionuclides in the spawn are rather mobile. Strontium separates fully from it during the first twenty four hours and yttrium marked by higher fixation strength transfers completely from the spawn into surrounding aqueous medium by the end of the experiment. In larvae the radionuclides are fixed stroger than in the spawn. The approximate radiation doses of embryos by the time of their hatching have been estimated. The estimates indicate that the total radiation dose of the spawn developing in aqueous solution of Sr-90 - Y-90 with 1.1 curie/0 -5 concentration is about 500 radl

    Objective To investigate the status of psychological health in the new prisoners, and to analyze the relationship between psychological health and personal self-esteem. Methods 100 new prisoners were assessed with Symptom Checklist 90 (SCL-90) and Rosenberg Self-esteem Scale (RSES) to evaluate their psychological health and self - esteem respectively. The relationship between psychological health and self - esteem was analyzed. Results Total score of SCL -90, the average score of SCL-90, number of positive items, factor scores of somatization, obsessive-compulsive , depression, anxiety, phobia, paranoid ideation and psychoticism were significantly higher than the national norm {P <0.05, or P <0. 01). The main psychological problems consisted of depression, obsessive-compulsive and anxiety etc. Gender, age, crime types and prison term showed effects on the psychological health. Total score of RSES was negatively correlated with total score of SCL-90, factor scores of obsessive-compulsive, interpersonal sensitivity, depression, anxiety, hostility and phobia. Self-esteem was a significant predictor variable for the total score of SCL-90 and factor scores of some items (P < 0. 05, or P < 0.01). Conclusion The psychological state of the new prisoners shows significantly abnormal. Self-esteem is a negative predictor variable for psychological state, the lower the level of self-esteem is, the worse the psychological state is. Self-esteem should be paid much attention while intervening the psychology of the new prisoners.%目的 探讨新入监服刑人员的心理健康状况及其与自尊水平之间的关系.方法 使用症状自评量表(SCL-90)和Rosenberg自尊量表(RSES)对100名新入监服刑人员的心理健康状况及自尊水平进行调查,并分析其相关性.结果 新入监服刑人员的SCL-90

    The {sup 90}Sr+{sup 90}Y applicators, used in betatherapy for prevention of keloids and pterigium, are imported and many times their dosimetric features are shown only in an illustrated form by the manufacturers. The exhaustive routine of the medical physicists in the clinic do not make possible the accomplishment of procedures for the confirmation of these parameters. This work presents the development of a methodology for the dosimetry of {sup 90}Sr+{sup 90}Y betatherapy applicators. The Monte Carlo code MCNP5 was used for the simulation of the percentage depth dose curves and dose distribution profiles produced by these applicators. The experimental measurements of the radial and axial radiation attenuation, have been done with a mini-extrapolation chamber, thermoluminescent dosimeters and radiographic films. The experimental results have been compared with the simulated values. Both percentage depth dose curves and the radial dose profiles, the theoretical and the experimental ones, have presented good agreement, which may validate the use of the MCNP5 for these simulations, confirming the viability of the usage of this method in procedures of beta emitter sources dosimetry.

    In the course of participating in the IAEA-CRP during the last two years, Vietnam has achieved the goal of setting up a {sup 90}Sr/{sup 90}Y generator system based on Supported Liquid Membrane (SLM) technique and also radiolabeling of the eluted {sup 90}Y with antibody, peptides and albumin. A two stage SLM based {sup 90}Sr-{sup 90}Y generator was set up in-house to generate carrier-free {sup 90}Y at different activity levels viz. 5, 20, 50 mCi. The generator system was operated in sequential mode in which 2-ethylhexyl 2-ethylhexyl phosphonic acid (PC88A) based SLM was used in the first stage for the transport {sup 90}Y in 4.0 M nitric acid from source phase where {sup 90}Sr-{sup 90}Y equilibrium mixture is placed in nitric acid medium at pH to 1-2. In the second stage, octyl (phenyl)-N,N-diisobutylcarbamoylmethyl phosphine oxide (CMPO) based SLM was used for the transport of {sup 90}Y selectively to 1.0 M acetic acid which is the best medium for radiolebeling. The eluted {sup 90}Y from the generator was tested for the presence of any traces of {sup 90}Sr using the Extraction Paper Chromatography (EPC) and was found suitable for radiolabeling. The generator system could be upgraded to 100 mCi level successfully due to an expert mission from India through IAEA. The {sup 90}Y product obtained from the generator system was used for radiolabeling of antibody and peptides viz. Rituximab, DOTATATE and albumin particles under different experimental conditions. A new chromatography system could be developed for analyzing {sup 90}Y labeled albumin using the TAE buffer as mobile phase in PC and ITLC.

    HIV-infected individuals on first-line antiretroviral therapy (ART) in resource-limited settings who do not achieve the last "90" (viral suppression) enter a complex care cascade: enhanced adherence counselling (EAC), repetition of viral load (VL) and switch to second-line ART aiming to achieve resuppression. This study describes the "failure cascade" in patients in Lesotho. Patients aged ≥16 years on first-line ART at 10 facilities in rural Lesotho received a first-time VL in June 2014. Those with VL ≥80 copies/mL were included in a cohort. The care cascade was assessed at four points: attendance of EAC, result of follow-up VL after EAC, switch to second-line in case of sustained unsuppressed VL and outcome 18 months after the initial unsuppressed VL. Multivariate logistic regression was used to assess predictors of being retained in care with viral resuppression at follow-up. Out of 1563 patients who underwent first-time VL, 138 (8.8%) had unsuppressed VL in June 2014. Out of these, 124 (90%) attended EAC and 116 (84%) had follow-up VL (4 died, 2 transferred out, 11 lost, 5 switched to second-line before follow-up VL). Among the 116 with follow-up VL, 36 (31%) achieved resuppression. Out of the 80 with sustained unsuppressed VL, 58 were switched to second-line, the remaining continued first line. At 18 months' follow-up in December 2015, out of the initially 138 with unsuppressed VL, 56 (41%) were in care and virally suppressed, 37 (27%) were in care with unsuppressed VL and the remaining 45 (33%) were lost, dead, transferred to another clinic or without documented VL. Achieving viral resuppression after EAC (adjusted odds ratio (aOR): 5.02; 95% confidence interval: 1.14-22.09; p  = 0.033) and being switched to second-line in case of sustained viremia after EAC (aOR: 7.17; 1.90-27.04; p  = 0.004) were associated with being retained in care and virally suppressed at 18 months of follow-up. Age, gender, education, time on ART and level of VL were not

    2001-01-01

    Several 90 Sr/ 90 Y-generator systems have been developed and used to produce 90 Y. The most important parameter of the 90 Y to be assayed is 90 Sr content. In addition, when labelling monoclonal antibodies for therapy trace metal quantities accompanying 90 Y (Fe 3+ , Zn 2+ , Cu 2+ , ZrO 2+ , etc.) are to be kept as low as possible in order to obtain high labelling efficiencies. Generally generators' lifetime is limited due to the 90 Sr breakthrough which increases in eluates as a result of the radiolytic degradation of the resin used as support. In the study a described procedure for 90 Y purification from metal contamination is modified in order to lower the amount of 90 Sr present in eluates from generators. As a result a very low 90 Sr content is always assured ( 90 Sr/ 90 Y -6 ). (author)

A 2 709 bp full-length cDNA sequence of heat shock protein 90 ( HSP90 ) gene from O. vulgaris was obtained by homologous amplification and rapid amplification of cDNA ends (RACE). It consisted of a 119 bp 5'untranslated region (UTR) ,a2 136 bp open reading frame(ORF)and a 454 bp 3'UTR. The inferred amino acids sequence was composed of 711 amino acids, whose molecular weight and isoelectric point were 81. 5 ku and 5. 09, respectively. Homologous analysis showed the inferred amino acids sequence was highly conserved and contained five classical HSP90 signature sequences. Real-time quantitative PCR ( RT-PCR) results displayed HSP90 expressed in every tissues chosen, with the most in liver. This study which was the first time to obtain HSP90 gene from Cephalopod played an important role in studying stress mechanisms on the most intelligent invertebrate.

    In 1965, Erling Jacobsen (1919-1988) defended his doctoral thesis on neurosis in which he tested the psychoanalytic theory of eridophobia as an internalising hostility factor with a specific causality for anxiety neurosis. He found no marked difference between anxiety neurosis and obsessive-compulsive neurosis, which, however, both differed from hysterical neurosis. The aim of this follow-up study was to evaluate to which extent anxiety neurosis and obsessive-compulsive neurosis when compared with hysterical neurosis co-existed with depression, both at the level of diagnostic behaviour, including committed suicide, and with regard to symptom profile. A total of 112 patients were followed on the Danish Central Psychiatric Research Register and the Danish Cause of Death Register with regard to their diagnostic behaviour. In a subset of the sample (n = 24), the patients were assessed using the Hopkins Symptom Checklist (SCL)-90. Both at the diagnostic level, including suicide rate, and at the level of symptom severity (SCL-90), anxiety neurosis and obsessive-compulsive neurosis were similar, in contrast to hysterical neurosis which had no more association with the other two categories of neurosis than would be expected by chance. Anxiety neurosis and obsessive-compulsive neurosis are more severe disorders than hysterical neurosis, both in terms of symptom profile and depression, including suicidal behaviour. The identified suicides were committed within the first two decades after discharge from the index hospitalisation. Poul M. Færgemann's Grant and the Neurosis Grant of 22 July 1959. not relevant.

  12. Perception ofown body by women with borderline personality disorder – preliminary studies

    Directory of Open Access Journals (Sweden)

    Aleksandra Szepietowska

    2014-03-01

    Full Text Available Aim: Analysis of the way women with borderline personality disorder (BPD perceive their bodies. Methods: The body perception was presented as a psychological model manifested in the attitude to one’s own body, the way of sensing and interpreting the bodily sensations, mental identification with the body, and the feeling of comfort in interpersonal closeness and social exposure situations. Material and methods: Twenty eight women took part in the study: 14 of them met the BPD criteria, 14 constituted a comparative group (selection by pairs. Three instruments were used: The Symptom Checklist-90 (SCL-90, self-constructed questionnaire examining one’s own body perception (Body Perception Scale – Skala Percepcji Ciała, SPC, and Borderline Scale from Structured Clinical Interview for DSM-IV Axis II Disorders (SCID-II to confirm BPD symptoms. Results: Women with BPD perceive their bodies more negatively in all examined aspects, as compared to those without personality disorders. Predominant are negative emotions towards one’s body and lack of confidence in one’s attraction for other people. Less intense become such traits as: the impression of perceptive changes, difficulty in identification with the body appearance, and avoidance of close physical contacts. Comparisons of SCL-90 results show that in women with BPD all psychopathological symptoms are more severe. These patients are characterized by an increased level of depressiveness, obsessive-compulsive traits, paranoid ideation, and psychoticism. The results profile shows a similar pattern of symptoms in both groups and it is not the type but severity of psychopathological symptoms that differentiates them.

    Full Text Available "n    "nObjective: Premenstrual syndrome (PMS is a common disorder with prevalence rate of approximately 30%; its concurrence with psychiatric symptoms will make it a disabling condition that resists usual treatment. Objective: This study was enrolled to assess the co-morbidity of PMS and psychiatric disorders in a sample of girls with PMS compared to those without PMS. "n    "nMaterial and method : This study was conducted through a cross sectional method with 362 participants (166 with PMS and 196 healthy girls who were selected randomly and completed the demographic questionnaire, premenstrual syndrome symptom daily record scale and the symptom checklist 90-revised (SCL-90-R. "n    "nResult: According to the result of the independent t test, the mean score of all the psychiatric symptoms in the PMS group was significantly higher than those in healthy group (P<0.001. According to SCL-90-R measurement, most of the participants in the PMS group were categorized as extremely sick for somatization (44% ,obsessive-compulsive (59%, depression (58.4%, anxiety (64.5%, hostility (47% and psychoticism (69.3%; most of the participants were diagnosed as having borderline severity of disorders for interpersonal sensitivity (44.6% and paranoid (42.8% and most of the respondents with PMS (46.4% were diagnosed as healthy only for phobic anxiety. "n    "nConclusion: There is a considerable relationship between PMS and different psychiatric symptoms that can complicate the diagnosis of PMS and its treatment for the health care providers. Therefore, all health care providers who are in contact with women in their reproductive age should be sensitive to mental health status in women with PMS.

    2016-03-01

    The purpose of this study is to shed light on therapy-relevant factors, such as self-esteem, self-efficacy, and resources in adults with ADHD in comparison with a healthy control group. A total of 43 adults who met Diagnostic and Statistical Manual of Mental Disorders (4th ed., text rev.; DSM-IV-TR) criteria for ADHD in adulthood were matched with a nonclinical sample in terms of age and gender. All participants (N = 86) were assessed with self-ratings: Symptom Checklist-90-Revised (SCL-90-R), Rosenberg Self-Esteem Scale, General Perceived Self-Efficacy Scale, and Dick's Resources Checklist. Adults with ADHD showed lower levels of self-esteem and self-efficacy when compared with the control group. The authors found some, but not all, of the resources of adults with ADHD to be reduced. In other words, people with ADHD seem to possess specific resources. Our results have important implications for the treatment of adult ADHD and suggest that specific therapy programs should include resources-oriented modules for enhancing self-esteem, self-efficacy, and fostering strengths. © The Author(s) 2012.

  15. The sequential separation of strontium-90, yttrium-90, promethium-147, and cerium-144 from urine and their subsequent estimation

    Kramer, G.H.; Davies, J.M.

    1981-04-01

    A method has been developed for separating low-level activities of the beta-emitting isotopes strontium-90, yttrium-90, promethium-147 and cerium-144 from urine and aqueous solutions. They are subsequently estimated by planchet or liquid scintillation counting. The radionuclides are separated from each other and from interfering elements by solvent extraction with HDEHP (di-2-ethylhexyl phosphoric acid) in n-heptane. It is possible to separate the elements with a minimum of cross-contamination by selecting appropriate pH's and solvent concentrations. Percentage recoveries for the radionuclides are: 90 Sr, 100 +- 12; 90 Y, 65 +- 4; 147 Pm, 90 +- 8; 144 Ce, 87 +- 11. The limits of detection are: 90 Sr, 0.6 pCi; 90 Y, 0.7 pCi; 147 Pm, 1.0 pCi; 144 Ce, 0.8 pCi. (author)

    In this work the results of studying the thermoluminescent properties (TL) of the doped zirconium oxide with europium (ZrO 2 : Eu 3+ ) before beta radiations of 90 Sr/ 90 Y are presented. The powders of ZrO 2 : Eu 3+ were obtained by means of the sol-gel technique and they were characterized by means of thermal analysis and by X-ray diffraction. The powders of ZrO 2 : Eu 3+ , previously irradiated with beta particles of 90 Sr/ 90 Y, presented a thermoluminescent curve with two peaks at 204 and 292 C respectively. The TL response of the ZrO 2 : Eu 3+ as function of the absorbed dose was lineal from 2 Gy up to 90 Gy. The fading of the information of the ZrO 2 : Eu 3+ was of 10% the first 2 hours remaining almost constant the information by the following 30 days. The ZrO 2 doped with the (Eu 3+ ) ion it was found more sensitive to the beta radiation that the one of zirconium oxide without doping (ZrO 2 ) obtained by the same method. Those studied characteristics allow to propose to the doped zirconium oxide with europium like thermoluminescent dosemeter for the detection of the beta radiation. (Author)

    Purpose: The aim of this study was to evaluate the results of keloidectomy and strontium 90 brachytherapy in the prevention of keloid recurrence following excision and to identify outcome and the prognostic factors that predict keloid recurrence after irradiation. Methods and Materials: Data of 612 patients with 892 keloids treated between 1992 and 2006 were evaluated retrospectively. Brachytherapy was performed using a Sr-90Y surface applicator. Total dose was 20 Gy in 10 fractions. Results: With a median follow-up of 61 months, the overall recurrence-free response rate for all keloids was 87.6%. Multivariate analysis revealed the following prognostic factors for recurrence: keloid size > 5 cm (p < 0.0001), burn scars as the keloid etiology (p < 0.0001), and previous treatment (p < 0.0001). Outcome was not found to be significantly related to the interval between surgery and radiotherapy, sex, or age. Pruritus and skin reddening were the most common symptoms of keloids, but all signs and symptoms abated with time after treatment. Cosmetic results from the keloid treatment were considered good or excellent in 70.6% of the patients. Conclusion: Our study findings show that excision plus Sr-90 brachytherapy is effective in the eradication of keloids. Sr-90 radiotherapy (20 Gy in 10 fractions) achieved a similar local control rate, as have higher doses per fraction in other series. It also resulted in a good cosmetic rate and relief of symptoms. Our data further suggest that the initiation of postoperative irradiation within hours of surgical excision is not important to therapeutic outcome.

    The children who experienced their parents' divorce when the divorce rate in Sweden had begun to grow to higher levels than in preceding decades are today adults. The aim of this study was to investigate if adults who had experienced parental divorce 15 years before the time of our study, differed in mental health from those with continuously married parents, taking into account life events other than the divorce. Instruments used were the Symptom Checklist (SCL-90) measuring mental health and the Life Event questionnaire capturing the number and experience of occurred events. Forty-eight persons, who were 7-18 years old when their parents divorced, constituted the divorce group, and 48 persons matched on age, sex and growth environment formed the study groups. The SCL-90 showed a limited difference between the groups, but not concerning total mental health. A main finding was a difference with regard to sex and age; women aged 22-27 in the divorce group displayed poorer mental health than other participants in both groups. The results from the Life Event questionnaire showed that the divorce group had experienced a significantly larger number of events, and more life events were described as negative with difficult adjustment. A regression analysis showed a significant relation between the SCL-90, Global Severity Index and life events experienced as negative with difficult adjustment, divorce events excluded, but not with the divorce itself. It seems highly desirable to pay more attention than has thus far been paid to girls with experience of childhood divorce at age 7-12.

Although there is a demonstrated need to improve the mental health and burnout levels among teachers, little is known about their mental health status, particularly with respect to graduating class teachers in remote mountain areas with undeveloped economies. The purpose of this study was to survey mental health and burnout among graduating class teachers in remote mountain areas and to examine the influence of moderating variables.Methods: We conducted a multilevel analysis of 590 graduating class teachers from 42 primary and secondary schools in remote mountain areas of Guangdong province in the People's Republic of China. The outcome variable of self-reported mental health was measured by the Symptom Checklist-90 (SCL-90, and burnout was measured by the Chinese Maslach Burnout Inventory for primary and secondary school teachers.Results: The status of both mental health and burnout among the respondents was significantly more troubling than the national norm used as a reference (P<0.05 or P<0.01. Each factor in the SCL-90 had a significant correlation with burnout (P<0.01. All factors of the SCL-90 were entered into the regression equation for each dimension of burnout (P<0.01.

    Full text: Management of persistent knee synovitis includes both systemic and local articular treatment relevant to specific etiology. Local treatment may involve attempts to control inflammation and pain in knee joints by intra articular application of analgesics or glucocorticoids. However, in many patients these fail to reduce significantly the synovitis phenomenon and moreover they may lead to severe side effects. Radiosynoviorthesis with Y90 has been in use for many years in several joint pathologies. Indications of Radiosynoviorthesis include various inflammatory and degenerative diseases and its use should be envisaged when other conservative methods have failed like intra articular injections of long acting corticosteroids. Persistent knee synovitis is defined by the presence of hydrops in the joint or functional impairment with warmth, pain and local signs and symptoms requiring intra articular injection of glucocorticoids. In this study, 151 knees with persistent knee synovitis have been treated with Y 90 and have had all a minimum of one year follow up. Many parameters have been identified to measure efficiency of the RSO including pain, hydarthrosis, mobility, as well as global perception of the patients. Excellent and good responses have been appreciated through pain at rest, pain at stress, volume of effusion, and articular mobility. Results showed that percentage of excellent and good response is superior to 80% at three and six months. Success of Y 90 appears to be higher for rheumatoid arthritis as well as for oligoarthritis. Whatever the etiology, intensity of the inflammatory process appears one the major parameters which could better predict the outcomes of yttrium 90 in persistent knee synovitis. (author)

  6. Heat shock protein 90 in neurodegenerative diseases

    2010-06-01

    Full Text Available Abstract Hsp90 is a molecular chaperone with important roles in regulating pathogenic transformation. In addition to its well-characterized functions in malignancy, recent evidence from several laboratories suggests a role for Hsp90 in maintaining the functional stability of neuronal proteins of aberrant capacity, whether mutated or over-activated, allowing and sustaining the accumulation of toxic aggregates. In addition, Hsp90 regulates the activity of the transcription factor heat shock factor-1 (HSF-1, the master regulator of the heat shock response, mechanism that cells use for protection when exposed to conditions of stress. These biological functions therefore propose Hsp90 inhibition as a dual therapeutic modality in neurodegenerative diseases. First, by suppressing aberrant neuronal activity, Hsp90 inhibitors may ameliorate protein aggregation and its associated toxicity. Second, by activation of HSF-1 and the subsequent induction of heat shock proteins, such as Hsp70, Hsp90 inhibitors may redirect neuronal aggregate formation, and protect against protein toxicity. This mini-review will summarize our current knowledge on Hsp90 in neurodegeneration and will focus on the potential beneficial application of Hsp90 inhibitors in neurodegenerative diseases.

  7. Development of Technology for the Preparation of 90Sr/90Y Generators at the Radiopharmacy Directory of IPEN/CNEN-SP

    90 Y (T /2 = 2,67 d; Eβmax = 2,28 MeV) is a radionuclide with efficacy established for various cancer therapies, labeling biomolecules and treating of radiosinovectomy. Due to its nuclear properties, is obtained through the decay of 90 Sr T /2 = 28 y in the form of a generator. Several types of 90 Sr/ 90 Y generators were developed, and the most employed are the cation exchange resins, where Sr and Y are adsorbed and 90 Y is selectively eluted with acetate or EDTA. The disadvantage of this type of generator is the radiolysis, which degrades its use. The electrochemical generator is a proposed solution because there is no significant effect of radiation. In this concept, the difference between the electrochemical potentials of the elements Sr and Y is used to obtain a rapid separation of 90 Y from 90 Sr. The production of 90 Y via colloid formation is the simplest method for the separation, based on the colloid formation of Y in high alkaline pH, which can be filtered and separated from Sr, and subsequently dissolved in HCl. The objective of this work was the development of technologies for the preparation of 90 Sr/ 90 Y generators, and three technologies were developed: generators using cation resins columns, generators through colloid formation and electrochemical generators. Radionuclidic quality control of 90 Y was also evaluated by liquid scintillation, radionuclide identity, extraction paper chromatography (EPC) using complexing agents for 90 Y and by Optical Emission Spectrometry with Inductively Coupled Plasma (ICP-OES). The results showed that generators using cation resins have the best results related to the elution efficiency (∼83%), the reproducibility and radionuclidic purity. The electrochemical generator showed a potential for development, having the advantage of not suffering the effects of radiolysis of the pair 90 Sr/ 90 Y as the resin. A comparison and evaluation of the methods of the radionuclidic quality control showed that the EPC is very

  10. Peculiarities of Sr-90 migration in the environment

    1991-01-01

    The Eastern Urals radioactive track which formed as a result of the Kyshtym accident constituted a natural experimental base for studying the dynamics of Sr-90 behaviour and migration in the environment. Sr-90 behaviour in soil depends on the processes involved in its physical migration horizontally (water runoff, wind transport) and vertically (effective diffusion), on the intensity with which the physico-chemical forms of strontium change, and primarily on Sr-90 incorporation into the soil-absorptive complex. Over 30 years the effective diffusion processes led to downward displacement of Sr-90 in undisturbed soil to a depth of 30 to 50 cm. In 1988 84-94% of the Sr-90 was located in the 10 cm layer as against 90% in the 2 cm layer in the initial 1 or 2 years. The amount of Sr-90 in mobile forms in leached chernozem and grey forest soil hardly changed over time, amounting to between 76 and 90%. In the first 5-10 years Sr-90 surface water runoff was about 0.2% (and Sr-90 wind resuspension 0.1-1.0%) per year of the Sr-90 inventory per unit area. Due to Sr-90 loss from the top soil layer the water runoff and wind resuspension processes decreased exponentially, halving every 4 to 5 years. In most cases, Sr-90 transfer from soil to plants via the roots does not involve discrimination of Sr-90 with regard to calcium, and therefore the Sr-90 accumulation level in various species of natural and agricultural plants depends on their calcium requirements and the amount of exchangeable calcium in the soil. This made it possible to work out quantitative indices for forecasting Sr-90 accumulation in various species of plants for given types of soil. As Sr-90 moves through the trophic chains (including the agricultural one) we find - depending on whether two adjoining links discriminate against it or not as regards calcium - that some organisms reject it while others concentrate it. When restoring farming on the contaminated territory the fact that cattle discriminated against Sr

    A major limitation on the supply of the short-lived medical isotope 90Y (t1/2 = 64 h) is the available quantity of highly purified 90Sr generator material. A radiochemical production campaign was therefore undertaken to purify 1,500 Ci of 90Sr that had been isolated from fission waste materials. A series of alkaline precipitation steps removed all detectable traces of 137Cs, alpha emitters, and uranium and transuranic elements. Technical obstacles such as the buildup of gas pressure generated upon mixing large quantities of acid with solid 90Sr carbonate were overcome through safety features incorporated into the custom-built equipment used for 90Sr purification. Methods are described for analyzing the chemical and radiochemical purity of the final product and for accurately determining by gravimetry the quantities of 90Sr immobilized on stainless steel filters for future use.

    The 90 Sr+ 90 Y beta-ray sources widely used in brachytherapy applications were developed in the 1950's. Many of these sources, called clinical applicators, are still routinely used in several Brazilian radiotherapy clinics for the treatment of superficial lesions in the skin and eyes, although they are not commercialized anymore. These applicators have to be periodically calibrated, according to international recommendations, because these sources have to be very well specified in order to reach the traceability of calibration standards. In the case of beta-ray sources, the recommended quantity is the absorbed dose rate in water at a reference distance from the source. Moreover, there are other important quantities, as the depth dose curves and the source uniformity for beta-ray plaque sources. In this work, depth dose curves were obtained and studied of five dermatological applicators, using thin thermoluminescent dosimeters of CaSO 4 :Dy and phantoms of PMMA with different thicknesses (between 1.0 mm and 5.0 mm) positioned between each applicator and the TL pellets. The depth dose curves obtained presented the expected attenuation response in PMMA, and the results were compared with data obtained for a 90 Sr+ 90 Y standard source reported by the IAEA, and they were considered satisfactory.

    At the start of gender reassignment therapy, persons with a gender identity disorder (GID) may deal with various forms of psychopathology. Until now, a limited number of publications focus on the effect of the different phases of treatment on this comorbidity and other psychosocial factors. The aim of this study was to investigate how gender reassignment therapy affects psychopathology and other psychosocial factors. This is a prospective study that assessed 57 individuals with GID by using the Symptom Checklist-90 (SCL-90) at three different points of time: at presentation, after the start of hormonal treatment, and after sex reassignment surgery (SRS). Questionnaires on psychosocial variables were used to evaluate the evolution between the presentation and the postoperative period. The data were statistically analyzed by using SPSS 19.0, with significance levels set at P < 0.05. The psychopathological parameters include overall psychoneurotic distress, anxiety, agoraphobia, depression, somatization, paranoid ideation/psychoticism, interpersonal sensitivity, hostility, and sleeping problems. The psychosocial parameters consist of relationship, living situation, employment, sexual contacts, social contacts, substance abuse, and suicide attempt. A difference in SCL-90 overall psychoneurotic distress was observed at the different points of assessments (P = 0.003), with the most prominent decrease occurring after the initiation of hormone therapy (P < 0.001). Significant decreases were found in the subscales such as anxiety, depression, interpersonal sensitivity, and hostility. Furthermore, the SCL-90 scores resembled those of a general population after hormone therapy was initiated. Analysis of the psychosocial variables showed no significant differences between pre- and postoperative assessments. A marked reduction in psychopathology occurs during the process of sex reassignment therapy, especially after the initiation of hormone therapy. © 2013

    A low power 20 GHz CMOS dynamic latched regeneration comparator for ultra-high-speed, low-power analog-to-digital converters (ADCs) is proposed. The time constant in both the tracking and regeneration phases of the latch are analyzed based on the small signal model. A dynamic source-common logic (SCL) topology is adopted in the master-slave latch to increase the tracking and regeneration speeds. Implemented in 90 nm CMOS technology, this comparator only occupies a die area of 65 × 150 μm2 with a power dissipation of 14 mW from a 1.2 V power supply. The measurement results show that the comparator can work up to 20 GHz. Operating with an input frequency of 1 GHz, the circuit can oversample up to 20 Giga-sampling-per-second (GSps) with 5 bits resolution; while operating at Nyquist, the comparator can sample up to 20 GSps with 4 bits resolution. The comparator has been successfully used in a 20 GSps flash ADC and the circuit can be also used in other high speed applications.

    Full Text Available El Symptom Checklist-90-R (SCL-90-R es uno de los instrumentos más ampliamente utilizados en la medición de la sintomatología psicopatológica en población clínica y en población general. Ya que gran parte de la investigación en psicopatología se realiza con estudiantes universitarios, este estudio instrumental pretende proporcionar datos de referencia para esta población. Analizamos las propiedades psicométricas de esta escala en una muestra representativa de 1.277 estudiantes de la Universidad de Girona. Las dimensiones con puntuaciones más elevadas para el total de la muestra son Obsesividad-compulsividad, Depresión y Sensibilidad interpersonal. Los resultados muestran diferencias significativas entre hombres y mujeres. La fiabilidad de la escala resulta muy aceptable, con unos coeficientes de consistencia interna de las nueve dimensiones primarias y del GSI, que oscilan entre 0,69 y 0,97. El análisis de la estructura factorial y la fuerte interdependencia entre las escalas primarias cuestionan la multidimensionalidad del SCL-90-R y refuerzan la idea de que el instrumento proporciona una medida de distrés general, es decir, es un indicador unidimensional de malestar psicológico más que una medida de dimensiones psicopatológicas diferenciadas.

    Growing evidence shows that temperamental features and emotional dysregulation are linked to Eating Disorders (EDs). Aim of this study was to explore the possible relationship between temperament and emotional eating (EE) from a dimensional standpoint, and the association of specific temperamental dimensions with overeating triggered by specific emotions. We enrolled 253 women with Anorexia Nervosa, Bulimia Nervosa and Binge Eating Disorder. Of those, 189 (74.7%), 73 (28.8%), and 80 (31.6%) reported binge eating, purging, or restrictive behaviors, respectively (the categories are not mutually exclusive). Participants completed the Emotional Eating Scale (EES), the Temperament and Character Inventory, the Eating Disorder Examination Questionnaire (EDE-Q) and the Symptom Checklist 90-Revised (SCL-90-R). Higher Persistence scores were found in the Restriction group, while the Binge group reported lower Persistence and higher Novelty Seeking scores. The Purge group showed lower Reward Dependence, Self Directedness and Cooperativeness scores. Patients with Purge also reported lower BMI and higher scores on EDE-Q restriction and eating concern subscales as well as higher scores for all SCL 90-R subscales. Patterns of association between temperamental traits and specific emotions were found in each group. Therefore, some temperamental features could be considered predictors of specific associations between emotions and the tendency to eat. Copyright © 2018. Published by Elsevier B.V.

    Sixty depressed patients and 52 normal controls completed three selfreport inventories: the Symptom Checklist-90 (SCL-90), the Beck Depression Inventory (BDI) and a new Verbal Style Investigation Schedule (VESIS) developed by the first author. The VESIS uses 16 key emotional and physical terms from Western inventories and identified the words and phrases most commonly used by Chinese patients to express these feeling states. Chinese subjects commonly used the key term itself for only 3 or the 16 key terms; they usually preferred to use other words or phrases to express the feeling state. We categorized these Chinese expressions into four styles of verbal expression: Psychological, Somatic, Neutral (i.e., a mixture of psychological and somatic) and Deficient (i.e., lack of expression because of denial or suppression). Three of the 12 key emotional terms of the VESIS (depressed, fearful, and anxiousness) were more commonly expressed in a somatic or neutral mode than the other key emotional terms. The key terms "suicidal interest" and "being punished" were more commonly expressed in a deficient style than other key emotional terms. The somatic factor score of the SCL-90 was not correlated with increased somatic expression of emotional states; thus patients who have multiple somatic complaints are not more likely to express emotions somatically. The hypothesis of somatization is discussed in light of this study.

    This study investigated the mental health status of medical students in China, and analyzed the influencing factors in order to provide evidence for mental health education for medical students. A stratified cluster sampling method was used to recruit medical students from Huazhong University of Science and Technology, China. The questionnaire survey on general information and Symptom Checklist 90 (SCL-90) were used for investigation and analysis. The results showed among the 1137 valid questionnaires, 278 (24.45%) participants had SCL-90 score ≥ 160. The top three mental problems of medical students were obsessive-compulsive disorder, interpersonal sensitivity and depression in terms of the factor score ≥ 2.5 and the number of participants who reflected on the diseases. The third-year medical students had the worst mental health status, and fifth-year medical students had the best mental health status. Students from rural area had more psychological problems than those from urban area; furthermore, students with high professional satisfaction, those who were the single child of the family, non-poor students, and those whose parents had high education level had better mental health status. It was concluded that the mental health of medical students is not optimistic in China. Medical students have some mental health problems of different degrees. Factors that influence the mental health of medical students include academic pressure, professional satisfaction level and family environment.

    To examine the predictive validity of the Parental Bonding Instrument (PBI) for outcome in individual and group psychotherapy. Data from four different clinical trials were combined, yielding a total of 105 patients. After controlling for gender, age and initial symptomatic distress, the predictive validity of the PBI subscales was investigated using the symptom checklist-90-revised (SCL-90-R) and inventory of interpersonal problems-64 (IIP-64) at termination as dependent measures in each treatment condition using separate hierarchical multiple regression analyses. Using the SCL-90-R at termination as dependent measure, reports of higher paternal and maternal care were related to a worse outcome in the Pesso-Boyden System Psychomotor condition, whereas reports of higher paternal care were related to a better outcome in the Cognitive-Behavioural Therapy condition. Also, higher maternal protection was related to a better outcome in the Cognitive-Behavioral Group condition. Using the IIP-64 at termination as dependent measure, reports of higher paternal protection were related to a better outcome in the Treatment As Usual condition. The study shows that the PBI may function as a clinical predictor for treatment response, although the results were somewhat contrary to previous reportings. Future studies should contrast and investigate possible differences between individual and group treatments further, as well as more clearly defined diagnostic groups. Clinical implications are presented. Copyright (c) 2008 John Wiley & Sons, Ltd.

    The aim of this study is to explore individual capacity for self-integration, susceptibility to the Rubber Hand Illusion (RHI) and the role of temperament factors in the emergence of body schema and body image dissociation. The RHI factors, proprioceptive drift, body ownership and body disownership were assessed in 48 university students. Personality and psychiatric vulnerability were measured by the Temperament and Character Inventory (TCI-R) and the Symptom Checklist-90-R (SCL-90-R). Our study pointed to the fact that the extent of behaviourally defined proprioceptive drift was associated with temperament factors, especially with Novelty Seeking and Harm Avoidance. Further, the ownership was associated with Symptom Checklist factors, especially with elevated Interpersonal Sensitivity and vulnerability to Schizotypy and Paranoid Ideation and elevated disownership score was found in the case of elevated Schizotypy, including a depersonalisation feeling when the RHI was induced. The RHI may be considered as a conflicting situation, in which a way to cope with incongruent multimodal, visual, haptic and proprioceptive stimulation provides an opportunity to test body integration and embodiment processes in healthy participants and patients without disadvantageous outcomes. The results support and replenish the two opposite processing models of the RHI with a third, temperament-based procedural mechanism. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

    Full Text Available Radioembolization (RE is a selective internal radiation therapy (SIRT delivering targeted, high-dose, intra-arterial radiation directly to the vascular supply of liver tumors. Complications can occur due to aberrant deposition or migration of radiation microspheres into nontarget locations, including normal hepatic parenchyma, lungs, pancreas, and upper gastrointestinal (UGI tract. We report a case of gastric ulcers due to yttrium-90 (90Y seed migration to the stomach to alert clinicians to this rare cause of gastric injury. A 57-year-old woman with stage IV breast cancer with liver and lung metastases presented to the hospital with 2 months of worsening nausea and vomiting. Two months prior, she had received SIRT with 90Y microspheres without complications. Upper GI endoscopy showed diffuse gastritis and extensive antral ulceration. Biopsies revealed black, spherical foreign bodies, consistent with 90Y microspheres, documenting radiation injury. Radiation-induced UGI ulceration is caused by direct radiation injury from beta-radiation. Delay in diagnosis may be due to the nonspecificity of symptoms and temporal delay of symptom onset from SIRT, which was 2 months in our patient. Also, complaints may be attributed erroneously to adjuvant chemotherapy or widespread metastatic disease. Clinicians must consider radiation-associated toxicity in any SIRT-treated patient developing abdominal symptoms.

    Full Text Available Background/Aim. Torture for political reasons is an extreme violence in interpersonal relations resulting in not only acute psychiatric disorders but also very often in very severe and far reaching negative consequences for the overall psychosocial functioning of a victim. The aim of this study was to investigate gender differences in types of torture and psychological consequences in subjects who experienced war torture. Methods. A sample (410 men and 76 women included clients of 'Centre for rehabilitation of torture victims - IAN, Belgrade' who experienced torture in prisons and concentration camps during civil wars in ex-Yugoslavia 1991-1995 and 1999. Types of Torture Questionnaire with 81 items was used for collecting data about forms of torture. Symptom Checklist 90-Revised (SCL-90- R was used for assessing type and intensity of psychological symptoms, and Impact of Event Scale (IES was used to estimate posttraumatic complaints. Results. A gender difference was found for 33 types of torture: 28 more frequent in men, and 5 in women. Factor analysis of torture types revealed three factors explaining 29% of variance: 'common torture', 'sadistic torture', and 'sexual torture'. Discriminant analysis revealed significant gender difference concerning the factors. 'Common torture' and 'sadistic torture' were more prominent in men, and 'sexual torture' was more present in women. Higher scores on depression, anxiety, somatization, interpersonal sensitivity and obsessive-compulsive dimensions on SCL-90-R were found in women. General score and scores of subscales (intrusion and avoidance on IES were significantly higher in women. Conclusion. Women exposed to war torture experienced less torture techniques and shorter imprisonment than men, but had more frequent and severe symptoms of posttraumatic stress disorder and other psychological symptoms. Gender differences in posttraumatic symptomatology can not be explained exclusively by gender differences

    An increased risk of autistic traits in Klinefelter syndrome (KS) has been reported. In addition, some studies have shown an increased incidence of gender dysphoria (GD) and paraphilia in autism spectrum disorder. The aim of this study was to evaluate the presence of (i) paraphilic fantasies and behaviors; and (ii) GD symptomatology in KS. A sample of 46 KS individuals and 43 healthy male controls (HC) were evaluated. Subjects were studied by means of several psychometric tests, such as Autism Spectrum Quotient (AQ) and Reading the Mind in the Eyes Revised (RME) to measure autistic traits, Gender Identity/GD questionnaire (GIDYQ-AA), and Sexual Addiction Screening Test (SAST). In addition, body uneasiness psychopathological symptoms were assessed using Symptom Checklist 90 Revised (SCL-90-R). The presence and frequency of any paraphilic fantasy and behavior was assessed by means of a clinical interview based on Diagnostic and Statistical Manual of Mental Disorders, 5th Edition criteria. Finally, all individuals included were assessed by Wechsler Adult Intelligence Scale-Revised to evaluate intelligence quotient (IQ). Data from a subsample of a previous published series of male to female GD individuals, with the battery of psychological measures useful to provide a psychopathological explanation of GD in KS population available, was also considered. When compared with HC, KS reported significantly lower total, verbal and performance IQ scores and higher SCL-90 obsession-compulsive symptoms (all P gender dysphoric symptoms than HC (P = 0.004), which were mediated by the presence of autistic traits (Sobel's test; P < 0.05). KS is associated with hypersexuality, paraphilic behaviors, and GD, which were mediated by obsessive-compulsive and autistic traits. © 2015 International Society for Sexual Medicine.

    The etiology and pathology of functional constipation (FC) is unclear. Some researches suggest that psychological factors may be related to this common problem. This study aimed to investigate the relationship between attention processing and emotional status in FC patients compared with healthy controls. We investigated selective attention and emotional status in patients with FC using the counting Stroop task. Thirty-five FC patients (FCP group) and 24 healthy controls (HCs) underwent an event-related potential (ERP) study while performing the task. Response time, latency and amplitude of P300 were collected and compared between the two groups. The Hamilton Depression Rating Scale (HAMD-17), Hamilton Anxiety Scale (HAMA), Symptom Checklist-90 (SCL-90) and Eysenck Personality Questionnaire (EPQ) were administered prior to the counting Stroop task. Scores for the FCP group differed significantly from those for the HCs on the HAMD-17, HAMA, SCL-90 (Global Severity Index, Positive Symptoms Total, dimensions of somatization, obsessive-compulsive, depression, anxiety, and psychosis), as well as extraversion and neurosis dimensions of the EPQ (P 0.05). ERP results showed prolonged latency at F4, additionally found enhanced activation at F3, FC1 and T8, and decreased activation at sites FC6 and P7 in the patients with FC. Statistically, significant differences of P300 latency at site F4 (P well as somatization, obsessive-compulsive tendencies and other neurotic personality characteristics. Patients may employ psychological defense mechanisms to avoid the pain of depression and anxiety. ERP results imply there may be some brain dysfunction and attention deficits in patients with FC.

    Clinicians generally agree on the association between depression and hypertension. Less clear is if the nature of the link is direct or indirect and if this should be considered confined only to syndromal forms or if it concerns also subsyndromal affective presentations. This study investigated the nature of the association between hypertension and subsyndromal depression in hospitalized hypertensive patients. 196 hypertensive and 96 non hypertensive inpatients underwent a SCID interview, to exclude patients positive for any Axis I or Axis II diagnosis. Symptomatic Subsyndromal Depression (SSD) was identified according to criteria proposed by Judd. Psychopathological assessment was performed with Anxiety Sensitivity Index (ASI) and Hopkins Symptom Checklist-90 (SCL-90). Clinical assessments included blood pressure measurement, evaluation of general health conditions and screening cardiovascular risk factors (smoke, alcohol, body weight, sedentary life style). Hypertensives met more frequently criteria for SSD. They also scored higher on ASI and SCL-90. However, those with more severe physical conditions, if compared with more healthy patients, did not show increased psychopathological severity. Similarly, psychopathological symptom severity did not differ among hypertensives positive for other cardiovascular risk factors, commonly more frequent among depressed subjects. Further analyses are needed to explore the potential advantage obtained on blood pressure control by treating SSD. Hospitalized hypertensives, more frequently satisfied criteria for Symptomatic Subsyndromal Depression. These milder affective forms are probably directly linked to the presence of hypertension, rather than being indirectly associated to physical impairment or to higher prevalence of other cardiovascular risk factors.

    Chronic alcohol use alters adaptive immunity and cytokine activity influencing immunological and hormone responses, inflammation, and wound healing. Brain cytokine disturbances may impact neurological function, mood, cognition and traits related to alcoholism including impulsiveness. We examined the relationship between plasma cytokine levels and self-rated psychiatric symptoms in 40 adult males (mean age 51 ± 6 years; range 33-58 years) with current alcohol dependence and 30 control males (mean age 48 ± 6 years; range 40-58 years) with no history of alcoholism using multiplex sandwich immunoassays with the Luminex magnetic-bead based platform. Log-transformed cytokine levels were analyzed for their relationship with the Symptom Checklist-90R (SCL-90R), Barratt Impulsivity Scales (BIS) and Alcoholism Severity Scale (ASS). Inflammatory cytokines (interferon γ-induced protein-10 (IP-10); monocyte chemoattractant protein-1 (MCP1); regulated on activation, normal T cell expressed and secreted (RANTES)) were significantly elevated in alcoholism compared to controls while bone marrow-derived hematopoietic cytokines and chemokines (granulocyte-colony stimulating factor (GCSF); soluble CD40 ligand (sCD40L); growth-related oncogene (GRO)) were significantly reduced. GRO and RANTES levels were positively correlated with BIS scales; and macrophage-derived chemokine (MDC) levels were positively correlated with SCL-90R scale scores (p alcoholism may influence brain function leading to increased impulsiveness and/or phobia. The novel association between RANTES and GRO and impulsivity phenotype in alcoholism should be further investigated in alcoholism and psychiatric conditions with core impulsivity and anxiety phenotypes lending support for therapeutic intervention.

    In this study we aimed to investigate the prevalance and clinical correlations of night eating syndrome (NES) in a sample of psychiatric outpatients. Four hundred thirthy three consecutive psychiatric out-patients older than 18years were evaluated in the outpatient clinics using clinical interview according to the DSM-IV with regard to psychiatric diagnosis. Participants were also screened for presence of NES utilizing both clinical interview and self report based on Night Eating Questionnaire (NEQ) instruments. Sociodemographic and clinical features such as age, gender, education level, socioeconomic level and body mass index (BMI) were also recorded. The Body Shape Questionnaire (BSQ) and the Symptom Checklist-90 Revised (SCL-90R) were administered. Based on the proposed diagnostic criteria of the NES via utilizing clinical interview method, 97 (32 male, 65 female) of the sample met diagnostic criteria for NES. The point prevalence of NES was 22.4%. No statistically significant differences were found between the two groups in terms of age, gender, marital status, education and BMI. The patients with NES had higher NEQ, BSQ and SCL-90R subscale scores than patients without NES. Prevalance of depressive disorder, impulse control disorder, and nicotine dependency was higher among patients with NES. No differences were found with regard to the medication (antipsychotics, antidepressants and mood stabilizers). Night eating syndrome is prevalent among psychiatric outpatients and associated with depression, impulse control disorder, and nicotine dependency. Body dissatisfaction and higher symptom severity are also other risk factors for the development of NES. Copyright © 2014 Elsevier Inc. All rights reserved.

    Full Text Available Syncope is defined as a transient loss of consciousness and absence of postural tone followed by spontaneous recovery. Neurally mediated syncope (vasovagal and idiopathic unexplained syncope (US are the most common causes of syncope. Syncope is a very limiting disease that, if recurrent, affects the patients’ physical and psychological health. Our objective from this study is to measure the prevalence of psychiatric symptoms among patients with US. All patients (>12 years with vasovagal or US who were evaluated in King Khalid University Hospital were identified. Echocardiography and table tilt test reports were reviewed and patients who had cardiac syncope (due to arrhythmia or structural heart disease were excluded (N = 18. Ninety-four patients were included for further psychiatric assessment. The patients were contacted to fill the Symptoms Checklist-90-Revised (SCL-90-R, which is a self-reporting questionnaire used to evaluate traits of depression, anxiety, somatization disorder and phobia. SCL-90-R scale has been translated to Arabic and validated in previous studies. Of the included cohort, 43 responded to fill the assessment scale, and 51 were excluded due to failure of communication (N = 41 or refusal to participate (N = 10. A control group was recruited with a case: control ratio of 1:3 matching for age, gender, and chronic illnesses.There were 43 patients and 129 control subjects, with predominance of females (67.4% and an average age of 33.8 (SD = 16. There was no difference in average scores of depression (13 vs. 14.53, P = 0.31, anxiety (11.3 vs. 10.4, P = 0.51, or phobia (5.4 vs. 5.2, P = 0.88. However, the syncope group had a higher average score for somatization disorder (18.53 vs. 13.66, P = 0.002. Binary logistic regression model was measured after grouping the cohort into above and below median scores.

    In this work the results of studying the thermoluminescent properties (TL) of the doped zirconium oxide with europium (ZrO{sub 2}: Eu{sup 3+}) before beta radiations of {sup 90}Sr/ {sup 90}Y are presented. The powders of ZrO{sub 2}: Eu{sup 3+} were obtained by means of the sol-gel technique and they were characterized by means of thermal analysis and by X-ray diffraction. The powders of ZrO{sub 2}: Eu{sup 3+}, previously irradiated with beta particles of {sup 90}Sr/ {sup 90}Y, presented a thermoluminescent curve with two peaks at 204 and 292 C respectively. The TL response of the ZrO{sub 2}: Eu{sup 3+} as function of the absorbed dose was lineal from 2 Gy up to 90 Gy. The fading of the information of the ZrO{sub 2}: Eu{sup 3+} was of 10% the first 2 hours remaining almost constant the information by the following 30 days. The ZrO{sub 2} doped with the (Eu{sup 3+}) ion it was found more sensitive to the beta radiation that the one of zirconium oxide without doping (ZrO{sub 2}) obtained by the same method. Those studied characteristics allow to propose to the doped zirconium oxide with europium like thermoluminescent dosemeter for the detection of the beta radiation. (Author)

    The dependence of 90 Sr uptake in the human organism on nutrition peculiarities is shown. Strontium-90 polluting vegetable products due to particle sorption from the air is less available for the uptake than 90 Sr resorbed from the soil with vegetation.

    Radioisotopes have been emitted around Japan due to a nuclear accident at the Fukushima Daiichi nuclear power station in March 2011. A problem is the contaminated water including the atomic nucleus which relatively has a long half- life time and soluble such as {sup 90}Sr, {sup 137}Cs. Internal exposures by {sup 90}Sr are more dangerous than {sup 137}Cs's because Sr has effective half-life time of 18 years and property of accumulation in a born. We have developed real-time {sup 90}Sr counter which is sensitive beta-ray of maximum kinematic energy of 2.28 MeV from {sup 90}Sr and insensitive of beta-ray of maximum kinematic energy of 1.17 MeV and gamma-ray from {sup 90}Sr by Cherenkov detection. This counter composes of Cerenkov counter, trigger scintillation counter and veto counter. Silica aerogel for Cherenkov counter can obtain refractive index between 1.017 and 1.049 easily. And wavelength shifting fiber (WLSF) is used as a light guide for extending effective area and producing lower cost. A mechanism of the identification of {sup 90}Sr is explained in following. In case of {sup 90}Sr, when the trigger counter reacts on the beta-ray from {sup 90}Sr, aerogel emits the Cherenkov light and WLSF reacts and read the Cherenkov light. On the other hand, in case of {sup 137}Cs, the trigger counter reacts on the beta-ray, aerogel stops the beta- ray and Cherenkov light is not emitted. Therefore, aerogel has a function as a radiator and shielding material. the gamma-ray is not reacted on the lower density detector. Cosmic rays would be also reacted by the veto counter.

    A thin window glas flow proportional counter is used to measure the 90 Sr- 90 Y and 89 Sr beta radioactivity in milk samples. A chemical procedure is used to separate strontium-yttrium from the other radionuclides present in milk. A calculation of the total efficiency of the system is performed which includes an empirical estimation of the backscattering factor. The calibration of the whole process allows the determination of the 90 Sr activity within 10% relative error in spite of uncertainties in the recovery yields of strontium and yttrium. No 89 Sr activity has been detected, and the mean value obtained for the 90 Sr activity in nine milk samples of Cantabria is 0.115 Bq/1 with a minimum detectable activity of 0.0105 Bq.

    Olsen, I.; Jonsen, J.

    1979-01-01

    The distribution patterns of 90 Sr in five littermate, 8-day-old Wistar rats were studied by whole body autoradiography. Rats were killed 15 min, 1, 4, 24, and 72 h after a single intraperitoneal injection of the isotope. Immediately after administration, 90 Sr was distributed throughout most of the soft tissues of the body. The soft tissue deposits had practically disappeared after 4 h. In the hard tissues of the body 90 Sr accumulated up to 24-72 h. Fifteen minutes after injection the uptake of 90 Sr in the enamel of the teeth was highest in the occlusal and incisal regions. 90 Sr gradually accumulated throughout the enamel and after 72 h its distribution in this layer was fairly uniform. Immediately after injection a narrow zone of radioactivity appeared in the dentin near the pulp. This zone broadened with time towards the dentinoenamel junction and included the intire dentin layer 72 h after injection. Initially, the uptake of 90 Sr was higher in the dentin than in the enamel, particularly in the cervical areas of the crown. This difference became less apparent with time. There was good correlation between the uptake in the teeth and bones, supporting the use of teeth as indicators of the 90 Sr body burden. (author)

    Estimates of 90 Sr intake via the total diet in New York City and San Francisco have been made since 1960 from quarterly food samplings and average consumption statistics. The dietary intake of 90 Sr has decreased from the maximum levels attained during 1963 to 1964, but the decline has become more gradual in recent years due to the continuing small amounts of 90 Sr deposition and the little-changing cumulative deposit of 90 Sr in soil. The annual intake in 1982 averaged 5.4 pCi/day (0.20 Bq/day) in New York, and 2.6 pCi/day (0.096 Bq/day) in San Francisco, little changed from the previous year. Further gradual reductions in 90 Sr intake are anticipated during 1983. 11 references, 7 figures, 4 tables

    This paper presents the process of the radiolabeling of microaggregated albumin particles with radionuclide Yttrium-90 using the directed method. The albumin microsphere kit was prepared in sodium phosphate buffer. The original solution includes 2 mg albumin particle and 0.5 mg stannous chloride dihydrate. The albumin particles size was ranged from 5 ?m to 30 ?m. The mixture was washed three times with phosphate buffer saline, pH 7.2 by centrifugation and suspended in 0.5 M sodium acetate buffer, pH 6. Yttrium - 90 in 1.0 M acetic acid was collected from 90 Sr/ 90 Y generator. The labeling of the particles with Y-90 (185 MBq) was performed at pH 5.5 in acetate buffer with agitating for 60 min at room temperature. The labeled albumin suspensions were centrifuged at 3000 rpm for 15 min. Labeling yields was calculated using centrifugation, filtration and compared with paper chromatography, which is developed in the Tris Acetic EDTA. In this system, the unbound of Y-90 migrates to an R f of 0.9-1.0 and the radiolabeled albumin particles remains at the point of origin (R f = 0). The size of 90 Y-albumin particles was compared with the albumin particles in the original solution to be sure that they did not change during the labeling treatment. The radiolabeling yields were more than 80%. The labeled compound was dialysis in phosphate buffer. The radiochemical purity was 98%. The 90 Y- albumin is an ideal radiopharmaceutical for potential use in malignant cancer treatment as brachytherapy. (author)

    2016-01-01

    A toxic accumulation of proteins is the hallmark pathology of several neurodegenerative disorders. Protein accumulation is regularly prevented by the network of molecular chaperone proteins, including and especially Hsp90. For reasons not yet elucidated, Hsp90 and the molecular chaperones interact with, but do not degrade, these toxic proteins resulting in the pathogenic accumulation of proteins such as tau, in Alzheimer's Disease, and α-synuclein, in Parkinson's Disease. In this review, we describe the associations between Hsp90 and the pathogenic and driver proteins of several neurodegenerative disorders. We additionally describe how the inhibition of Hsp90 promotes the degradation of both mutant and pathogenic protein species in models of neurodegenerative diseases. We also examine the current state of Hsp90 inhibitors capable of crossing the blood-brain barrier; compounds which may be capable of slowing, preventing, and possible reversing neurodegenerative diseases.

    The research for species characterization of 90 Y and 90 Sr complex compound have been conducted using variation of buffer, concentration of HCl, electrophoresis operation voltage, time of electrophoresis, and electrophoresis migration media. From many trials, the conclusions are the applicable buffer are tartrate buffer and citrate buffer. These buffers can make a complex compound of 90 Y and there is migration to the anode. But, 90 Sr can’t make any complex compound and migration to the cathode. The optimum concentration of hydrochloride acid is 8 M with tartrate buffer but for citrate buffer, the concentration HCl is 2 M. The hydrochloric acid is used to dissolved the both elements as the mentioned above, but also for making complex ligand. The optimum electrophoresis operation voltage is 200 Volt for the both buffer solution and the duration of electrophoresis operation is 2.5 hours with using tartrate buffer but for citrate buffer the duration is 2 hours. The media of migration which can be used for replacing paper is silica. (author)

    In this work the results of studying the thermoluminescent properties (Tl) of the zirconium oxide in its amorphous state (ZrO 2 -a) before beta radiations of 90 Sr/ 90 Y are presented. The amorphous powders of the zirconium oxide were synthesized by means of the sol-gel technique. The sol-gel process using alkoxides like precursors, is an efficient method to prepare a matrix of zirconium oxide by hydrolysis - condensation of the precursor to form chains of Zr-H 3 and Zr-O 2 . One of the advantages of this technique is the obtention of gels at low temperatures with very high purity and homogeneity. The powders were characterized by means of thermal analysis and by X-ray diffraction. The powders of ZrO 2 -a, previously irradiated with beta particles of 90 Sr/ 90 Y, presented a thermoluminescent curve with two peaks at 150 and 257 C. The dissipation of the information of the one ZrO 2 -a was of 40% the first 2 hours remaining constant the information for the following 30 days. The reproducibility of the information was of ± 2.5% in standard deviation. The studied characteristics allow to propose to the amorphous zirconium oxide as thermoluminescent dosemeter for the detection of beta radiation. (Author)

    Hsp90, a homodimeric ATPase, is responsible for the correct folding of a number of newly synthesized polypeptides in addition to the correct folding of denatured/misfolded client proteins. It requires several co-chaperones and other partner proteins for chaperone activity. Due to the involvement of Hsp90-dependent client proteins in a variety of oncogenic signaling pathways, Hsp90 inhibition has emerged as one of the leading strategies for anticancer chemotherapeutics. Most of Hsp90 inhibitors blocks the N terminal ATP binding pocket and prevents the conformational changes which are essential for the loading of co-chaperones and client proteins. Several other inhibitors have also been reported which disrupt chaperone cycle in ways other than binding to N terminal ATP binding pocket. The Hsp90 inhibition is associated with heat shock response, mediated by HSF-1, to overcome the loss of Hsp90 and sustain cell survival. This review is an attempt to give an over view of all the important players of chaperone cycle. Copyright © 2016 Elsevier B.V. and Société Française de Biochimie et Biologie Moléculaire (SFBBM).

    Full Text Available One of the key points in the double measurement method for the measurement of both, 89Sr and 90Sr, by using a proportional counter is the choice of the times at which the measurements should be done. In this paper, the formulae to calculate the 89Sr and 90Sr detection limits in conditions of radioactive equilibrium between 90Y and 90Sr are derived, and an analysis of them as a function of the time between the two measurements is done. The choice for the time of the second measurement is going to depend on the desired quality of the results to be obtained.

    1991-01-01

    An anti-carcinoembryonic antigen (CEA) antibody, NP-4, was labeled with 90 Y using p-isothiocyanatobenzyl DTPA (SCN-Bz-DTPA) and its derivatives 1-(p-isothiocyanatobenzyl)-3-methyl-DTPA (1B3M), 2-(p-isothiocyanatobenzyl)-4-methyl-DTPA (1M3B), 1-(2)-methyl-4-isothiocyanatobenzyl-DTPA (MX-DTPA) as the chelating agents. The 90 Y conjugates were purified from unbound 90 Y by two different methods, HPLC or acrylamide size exclusion gel chromatography, in order to evaluate the best purification method. Labeling efficiency, reaction kinetics and immunoreactivity were compared to the same antibodies labeled with [ 111 In]citrate. Labeling efficiency, as determined by either HPLC or ITLC (instant thin layer chromatography), was consistently higher by ITLC than HPLC for 90 Y-labeled MAb, but equal for 111 In-labeled MAbs. Discrepancies between the 2 methods were linked to impurities in the 90 Y that remained at the origin of ITLC plates. After purification by acrylamide gel filtration, recovery was 50-60% of loaded 90 Y activity, but was more than 87% for the 111 In compounds. Using HPLC, the recovery measured 85% for 90 Y-labeled MAb and more than 93% for 111 In-labeled conjugates. Immunoreactivity of the [ 90 Y]MAb was comparable to the 111 In-labeled conjugates. These studies indicate that HPLC purification of the [ 90 Y] MAbs improves recovery of activity, and suggests that impurities found in the 90 Y and metal-binding properties of acrylamide may have contributed to the poor recoveries from acrylamide gels.

    Many causes including the chronicity of disease, burden of treatment modalities, morbidities, and the expectation of early death resulting from the disease complications, may lead to psychosocial burden in Thalassemia Major (TM) patients. A total of 38 patients with TM and their mothers were recruited to evaluate the psychosocial burden as well as to disclose whether the psychological status of the patients contribute to the compliance with the therapy or to the contrary. Demographic and disease variables were obtained. Child Behavior Check-list (CBCL) was completed by the mothers of the patients. A detailed psychiatric interview based on the 4th edition of the Diagnostic and Statistical Manual diagnostic criteria was performed for each patient. Symptom Distress Checklist 90 (SCL-90) scale was given to all mothers for evaluating their psychopathology. Although CBCL scores remained between the normal ranges, desferrioxamine mesylate (DFO)-compliant patients and the patients with lower ferritin values had significantly higher scores. A total of 24% of the patients had a psychiatric diagnosis including major depression, anxiety disorder, tic disorder, and enuresis nocturnal. The psychiatric diagnosis was significantly higher in the patients who were compliant with desferrioxamine compared with the non-compliant group (P = 0.007). The SCL-90 scores indicated that the mothers who had a child with good adherence to DFO had higher scale scores than the mothers with a poor adherent child. The increase risk of psychosocial and behavioral problems in thalassemics and their parents indicated the importance of a lifelong psychosocial support for the prevention of mental health issues. The patients and their parents, who were more conscious of the illness, were more worried but more compliant with the therapy and need stronger psychiatric support.

    Multimodal treatment of children with ADHD often includes parent-child training (PCT). However, due to the high heritability, parents of children with ADHD are frequently also affected by the disorder, which is likely to constitute a significant barrier to successful treatment of the child. This secondary analysis of our randomized controlled multicentre AIMAC trial (ADHD in mothers and children) investigates whether children's outcomes following parent-child training in combination with maternal ADHD treatment depend on maternal symptom improvement. In a first step focusing on treatment of maternal ADHD, 144 mothers of mother-child dyads were randomized to multimodal ADHD treatment (group psychotherapy plus methylphenidate) or clinical management (mainly supportive counselling). After 12 weeks (T2), a 12-week PCT program (T2-T3) for all mother-child dyads was added to treat children's ADHD. Maternal symptomatology (CAARS-O:L; SCL-90-R) and children's externalizing symptoms (ADHD-ODD Scale, SDQ) were repeatedly assessed (T1 = baseline, T2, T3). Effects of changes in maternal symptomatology (T1-T2) on the change in children's symptom scores (T1-T3) were analysed using a general linear model, controlling for baseline scores, study centre, and maternal treatment group. 125 mother-child dyads were analysed. Mothers showed significant improvements in ADHD symptoms and overall psychopathology [CAARS-O:L ADHD index: mean - 3.54, SE 0.74 p < 0.0001; SCL-90-R Global Severity (GS): mean - 11.03, SE 3.90, p = 0.0056]. Although children's externalizing symptoms improved significantly (ADHD-ODD Scale: mean - 4.46, SE 0.58, p < 0.0001), maternal improvement had no effect on children's outcomes after Bonferroni-Holm correction for multiple testing. The findings do not support our hypothesis that children's outcomes following PCT for ADHD depend on maternal symptom improvements.Trial register CCT-ISRCTN73911400.

    A simple solvent extraction method has been developed for the separation of 90 Y from 90 Sr. Crown ether dissolved in chloroform was used as a selective reagent and organic picrate anion was chosen as a counter ion. The effect of various factors on the extraction equilibrium constant of strontium log K ex = 9.15 was obtained from the study of the distribution coefficient versus to crown ether concentration. The separation method was simple, resulted high purity (>99.9%) and quantitative yield, and took less than half an hour. (author) 27 refs.; 4 figs.; 4 tabs

    This report describes data obtained during a preliminary characterization of 90 Sr levels in browse vegetation from the vicinity of seeps adjacent to ORNL solid waste storage areas (SWSA) where deer (Odocoileus virginianus) were suspected to accumulate 90 Sr through the food chain. The highest strontium concentrations in plant samples were found at seeps associated with SWSA-5. Strontium-90 concentrations in honeysuckle and/or blackberry shoots from two seeps in SWSA-5 averaged 39 and 19 nCi/g dry weight (DW), respectively. The maximum concentration observed was 90 nCi/g DW. Strontium-90 concentrations in honeysuckle and blackberry shoots averaged 7.4 nCi/g DW in a study area south of SWSA-4, and averaged 1.0 nCi/g DW in fescue grass from a seepage area located on SWSA-4. A simple model (based on metabolic data for mule deer) has been used to describe the theoretical accumulation of 90 Sr in bone of whitetail deer following ingestion of contaminated vegetation. These model calculations suggest that if 30 pCi 90 Sr/g deer bone is to be the accepted screening level for retaining deer killed on the reservation, then 5-pCi 90 Sr/g DW vegetation should be considered as a possible action level in making decisions about the need for remedial measures, because unrestricted access and full utilization of vegetation contaminated with 90 Sr bone concentrations of <30 pCi/g in a 45-kg buck

    It is important for public safety to monitor strontium-90 in aquatic environments in the vicinity of nuclear related facilities. Strontium-90 concentrations in seawater exceeding the background level have been observed in accidents of nuclear facilities. However, the analytical procedure for measuring strontium-90 in seawater is highly demanding. Here we show a simple and high throughput analytical technique for the determination of strontium-90 in seawater samples using a direct yttrium-90 separation. The DGA Resin is used to determine the abundance of strontium-90 by detecting yttrium-90 decay (beta-emission) in secular equilibrium. The DGA Resin can selectively collect yttrium-90 and remove naturally occurring radionuclides such as (40)K, (210)Pb, (214)Bi, (238)U, and (232)Th and anthropogenic radionuclides such as (140)Ba, and (140)La. Through a sample separation procedure, a high chemical yield of yttrium-90 was achieved at 95.5±2.3%. The result of IAEA-443 certified seawater analysis (107.7±3.4 mBq kg(-1)) was in good agreement with the certified value (110±5 mBq kg(-1)). By developed method, we can finish analyzing 8 samples per day after achieving secular equilibrium, which is a reasonably fast throughput in actual seawater monitoring. By processing 3 L of seawater sample and applying a counting time of 20 h, minimum detectable activity can be as low as 1.5 mBq kg(-1), which could be applied to monitoring for the contaminated marine environment. Reproducibility was found to be 3.4% according to 10 independent analyses of natural seawater samples from the vicinity of the Fukushima Daiichi Nuclear Power Plant in September 2013.

    A major limitation on the supply of the short-lived medical isotope {sup 90}Y (t{sub 1/2}=64 h) is the available quantity of highly purified {sup 90}Sr generator material. A radiochemical production campaign was therefore undertaken to purify 1500 Ci of {sup 90}Sr that had been isolated from fission waste materials. A series of alkaline precipitation steps removed all detectable traces of {sup 137}Cs, alpha emitters, and uranium and transuranic elements. Technical obstacles such as the buildup of gas pressure generated upon mixing large quantities of acid with solid {sup 90}Sr carbonate were overcome through safety features incorporated into the custom-built equipment used for {sup 90}Sr purification. Methods are described for analyzing the chemical and radiochemical purity of the final product and for accurately determining by gravimetry the quantities of {sup 90}Sr immobilized on stainless steel filters for future use.

    Full Text Available Enteric protozoan Entamoeba histolytica is a major cause of debilitating diarrheal infection worldwide with high morbidity and mortality. Even though the clinical burden of this parasite is very high, this infection is categorized as a neglected disease. Parasite is transmitted through feco-oral route and exhibit two distinct stages namely – trophozoites and cysts. Mechanism and regulation of encystation is not clearly understood. Previous studies have established the role of Heat shock protein 90 (Hsp90 in regulating stage transition in various protozoan parasites like Giardia, Plasmodium, Leishmania and Toxoplasma. Our study for the first time reports that Hsp90 plays a crucial role in life cycle of Entamoeba as well. We identify Hsp90 to be a negative regulator of encystation in Entamoeba. We also show that Hsp90 inhibition interferes with the process of phagocytosis in Entamoeba. Overall, we show that Hsp90 plays an important role in virulence and transmission of Entamoeba.

    99m Tc, the result of the radioactive decay of 99 Mo, is one of the most applied radioisotopes in nuclear medicine and is used in nuclear medicine as a radiopharmaceutical product. It is important to ensure 99 Mo quality in order to fit the 99m Tc quality specifications. The main objective was to obtain a technique for 90 Sr determination in 99 Mo and environmental samples. The purification of 90 Sr is performed by extraction chromatography where crown-ether resin (Sr-Spec, Eichrom) was used. The measurement of the 90 Sr activity is performed by Liquid Scintillation Counting (LSC) using the double windows method. This method permits the 90 Sr determination without waiting until radiochemical equilibrium 90 Sr / 90 Y has been reached. The recovery factor was determined by gamma spectrometry with 85 Sr, and by gravimetry with stable strontium carrier solution. The minimum detectable activity was 0,05 Bq. The recovery factor was the major contribution in the total uncertainty. (author)

    The determination of {sup 90}Sr in bones by dosage of its daughter product {sup 90}Y is a 4-step process: 1) elimination of the phosphate ions by precipitation of the Ca and Sr as oxalate in the presence of acid; 2) reduction in the calcium concentration to a suitable level by the addition of a known volume of nitric acid (a single precipitation is sufficient), the precipitation yield of the strontium nitrate is checked by the measurement of the amount of {sup 85}Sr added as tracer; 3) purification by a yttrium hydroxide precipitation; 4) extraction at equilibrium of the {sup 90}Y which is counted to give the concentration. By using 50 gm of ash it is possible to detect about 0.1 pCi of {sup 90}Sr per gram of calcium. The advantages of this technique: -) treatment of a large quantity of bone ash -) the use of a small volume of nitric acid (less than 2 ml/g of ash, and -) the various operations present no difficulty.

    Full Text Available Abstract Background The aim of our study was to assess psychiatric symptoms in patients with genetically proven primary mutation of the mitochondrial DNA. Methods 19 adults with known mitochondrial mutation (MT have been assessed with the Stanford Health Assessment Questionnaire 20-item Disability Index (HAQ-DI, the Symptom Check List-90-Revised (SCL-90-R, the Beck Depression Inventory-Short Form (BDI-SF, the Hamilton Depression Rating Scale (HDRS and the clinical version of the Structured Clinical Interview for the the DSM-IV (SCID-I and SCID-II As control, 10 patients with hereditary sensorimotor neuropathy (HN, harboring the peripheral myelin protein-22 (PMP22 mutation were examined with the same tools. Results The two groups did not differ significantly in gender, age or education. Mean HAQ-DI score was 0.82 in the MT (range: 0-1.625 and 0.71 in the HN group (range: 0-1.625. Level of disability between the two groups did not differ significantly (p = 0.6076. MT patients scored significantly higher on the BDI-SF and HDRS than HN patients (12.85 versus 4.40, p = 0.031, and 15.62 vs 7.30, p = 0.043, respectively. The Global Severity Index (GSI of SCL-90-R also showed significant difference (1.44 vs 0.46, p = 0.013 as well as the subscales except for somatization. SCID-I interview yielded a variety of mood disorders in both groups. Eight MT patient (42% had past, 6 (31% had current, 5 (26% had both past and current psychiatric diagnosis, yielding a lifetime prevalence of 9/19 (47% in the MT group. In the HN group, 3 patients had both past and current diagnosis showing a lifetime prevalence of 3/10 (30% in this group. SCID-II detected personality disorder in 8 MT cases (42%, yielding 3 avoidant, 2 obsessive-compulsive and 3 personality disorder not otherwise specified (NOS diagnosis. No personality disorder was identified in the HN group. Conclusions Clinicians should be aware of the high prevalence of psychiatric symptoms in patients with

    The present paper explained the turbofan engine GE90 which is being developed by General Electric Co., USA. That engine is to meet the thrust (takeoff thrust) of 300 to 530kN as required for the new-generation wide-fuselage civil transport plane which is being designed for its planned operation in the 1990's. In April, 1991, the world's strongest thrust of 480kN was achieved with engine elements also confirmed through element test. Thereafter, the engine underwent a flying test on board of Boeing 747 to materialize the planned operation in 1995. Made to be 9 in by-pass ratio and about 40 in overall pressure ratio, the GE90 was given the concept that advantage could be secured in both propulsive efficiency and thermal efficiency. That concept could be materialized by the development of composite fan blade technology and energy-efficient technology which were both demonstrated with an unducted fan. In spite of its pressure ratio of 22, the GE90's high pressure compressor demonstrates its polytropic efficiency which is equal to that of the low pressure ratio compressor. 3 refs., 19 figs., 1 tab.

    The migration and distribution of radionuclide 90 Sr were conducted by the analysis of 97 soil longitudinal sections under natural conditions and by pot experiments with fallout and 90 Sr solution, respectively. Spring wheat and rice were employed in the pot experiments. The result showed that the radionuclide 90 Sr was mainly accumulated in the topsoil 0-10 cm under both of the natural and laboratory conditions. The vertical distribution of 90 Sr in soil agreed with the power function, which obtained was Y = 75.78 X -0.527 ; r = -0.986; n = 97. The existing forms of 90 Sr from fallout in soil, only 0.02-0.03% was in a soluble form and 0.06-0.07% in non-replaceable form

    Social and political instability have become common situations in many parts of the world. Exposure to different types of traumatic circumstances may differentially affect psychological status. The aim of this study was to compare the relationship between personal perceptions of control over the events happening in one's life and psychological distress in two groups who experienced physical trauma but differed as to whether the trauma was a result of political upheaval and violence. Views on the extent to which the state was interested in the individual were also assessed. The sample consisted of 120 patients who were injured in the Cairo epicenter and 120 matched controls from the greater Cairo area whose injuries were from other causes. The Brown Locus of Control Scale and the Symptom Checklist-90-Revised (SCL 90-R) were administered approximately three months after the January 2011 start of the demonstrations and subsequent overthrow of the government. The groups did not differ on locus of control. For both groups, externality was associated with greater distress, suggesting a relationship between perceived helplessness in controlling one's life and distress. The Cairo group scored significantly higher than the control group on the SCL 90-R Global Severity Index (GSI) and Positive Symptom Total (PST). Perceptions of state interest in the population were low; overall, 78% viewed the state as having little or no interest in them. Discussion The relationship between exposure intensity and psychological distress is examined. In addition, differences in findings in populations experiencing political chaos compared with other types of disasters are considered. Beliefs regarding personal control over one's life circumstances are more closely associated with psychological distress than the circumstances in which the trauma occurred.

    In this work the results of studying the thermoluminescent properties (Tl) of the zirconium oxide in its amorphous state (ZrO{sub 2}-a) before beta radiations of {sup 90} Sr/ {sup 90} Y are presented. The amorphous powders of the zirconium oxide were synthesized by means of the sol-gel technique. The sol-gel process using alkoxides like precursors, is an efficient method to prepare a matrix of zirconium oxide by hydrolysis - condensation of the precursor to form chains of Zr-H{sub 3} and Zr-O{sub 2}. One of the advantages of this technique is the obtention of gels at low temperatures with very high purity and homogeneity. The powders were characterized by means of thermal analysis and by X-ray diffraction. The powders of ZrO{sub 2}-a, previously irradiated with beta particles of {sup 90} Sr/{sup 90} Y, presented a thermoluminescent curve with two peaks at 150 and 257 C. The dissipation of the information of the one ZrO{sub 2}-a was of 40% the first 2 hours remaining constant the information for the following 30 days. The reproducibility of the information was of {+-} 2.5% in standard deviation. The studied characteristics allow to propose to the amorphous zirconium oxide as thermoluminescent dosemeter for the detection of beta radiation. (Author)

    1979-01-01

    A typical liquid scintillation counter was evaluated for detection of low levels of 90 Sr-Y. A blank of about 5 cpm and 90 Y efficiency of 42% were obtained for 20-ml samples. The corresponding minimum detectable concentration for a 100-minute count is 0.03 pCi/ml, so that measurement of water samples can readily be made at the maximum permissible concentration for 90 Sr, 0.3 pCi/ml. The efficiency for 90 Sr is less than 0.4%, 1.4% for 137 Cs, and less than 0.04% for gamma-emitting 85 Sr, a useful tracer. Some data for 90 Y efficiencies and blanks are given for other liquid scintillation counters. Chemical treatments are necessary in some cases to concentrate 90 Sr-Y, to remove colored substances which cause quenching, or to eliminate interfering radionuclides. However, the manipulations need not be as elaborate as in conventional radiochemical analysis methods for 90 Sr. Ferric ion (yellow) quenches at the 5 ppM level, but the interference can be eliminated by adding a reducing agent. The Rn daughter 214 Bi, an interfering radionuclide, disappears by decay in 2-3 hours after removal of Rn by sweeping with air or gas. Concentration-separation methods studied have included precipitation and ion exchange

    Estimates of 90 Sr intake via the total diet in New York City and San Francisco have been made since 1960 from quarterly food samplings and average consumption statistics. The dietary intakes of 90 Sr have decreased from the maximum levels attained during 1963 to 1964, but the declines have become more gradual in recent years due to the continuing small amounts of 90 Sr deposition and the little-changing cumulative deposit of 90 Sr in soil. The annual intake in 1980 averaged 6.0 pCi/day (0.22 Bq/day) in New York and 2.5 pCi/day (0.092 Bq/day) in San Francisco, slightly lower than the results of the previous year. Further gradual reductions in 90 Sr intake are anticipated during 1981

  1. Structure, Function and Regulation of the Hsp90 Machinery

    Directory of Open Access Journals (Sweden)

    Jing Li

    2013-06-01

    Full Text Available Heat shock protein 90 (Hsp90 is an ATP-dependent molecular chaperone which is essential in eukaryotes. It is required for the activation and stabilization of a wide variety of client proteins and many of them are involved in important cellular pathways. Since Hsp90 affects numerous physiological processes such as signal transduction, intracellular transport, and protein degradation, it became an interesting target for cancer therapy. Structurally, Hsp90 is a flexible dimeric protein composed of three different domains which adopt structurally distinct conformations. ATP binding triggers directionality in these conformational changes and leads to a more compact state. To achieve its function, Hsp90 works together with a large group of cofactors, termed co-chaperones. Co-chaperones form defined binary or ternary complexes with Hsp90, which facilitate the maturation of client proteins. In addition, posttranslational modifications of Hsp90, such as phosphorylation and acetylation, provide another level of regulation. They influence the conformational cycle, co-chaperone interaction, and inter-domain communications. In this review, we discuss the recent progress made in understanding the Hsp90 machinery.

    HSP90 acts as a protein-folding buffer that shapes the manifestations of genetic variation in model organisms. Whether HSP90 influences the consequences of mutations in humans, potentially modifying the clinical course of genetic diseases, remains unknown. By mining data for >1,500 disease-causing mutants, we found a strong correlation between reduced phenotypic severity and a dominant (HSP90 ≥ HSP70) increase in mutant engagement by HSP90. Examining the cancer predisposition syndrome Fanconi anemia in depth revealed that mutant FANCA proteins engaged predominantly by HSP70 had severely compromised function. In contrast, the function of less severe mutants was preserved by a dominant increase in HSP90 binding. Reducing HSP90's buffering capacity with inhibitors or febrile temperatures destabilized HSP90-buffered mutants, exacerbating FA-related chemosensitivities. Strikingly, a compensatory FANCA somatic mutation from an "experiment of nature" in monozygotic twins both prevented anemia and reduced HSP90 binding. These findings provide one plausible mechanism for the variable expressivity and environmental sensitivity of genetic diseases. Copyright © 2017 Elsevier Inc. All rights reserved.

  3. ROV90 - A prototype autonomous inspection vehicle

    Energy Technology Data Exchange (ETDEWEB)

    Roedseth, Oe.J.; Hallset, J.O.

    1991-04-01

    Simple autonomous inspection vehicles are suitable for operations where the cost, danger to humans, or area of operation prohibits the use of conventional underwater technology. Autonomous vehicles are, however, in their infancy and few such vehicles are available. There are still some problems to be overcome before this technology becomes useful in commercial applications. We have built ROV90 to investigate these problems. It is a test bed for experimenting with the different parts of an autonomous underwater vehicle. ROV90 will be able to autonomously follow prominent features in the real world, man made or natural. Examples are pipelines or walls in tunnels. ROV90 is tethered, but we are planning to use experience and results from ROV90 to develop av ''real'' autonomous underwater vehicle (AUV) called PISCIS. 11 refs., 8 figs.

  4. Test for the determination of 90Sr in soil

    International Nuclear Information System (INIS)

    1980-01-01

    The standardized method is based on the chemical separation (extraction, precipitation, etc.) of 90 Sr from other fission products. After long-term storage for 90 Sr- 90 Y equilibrium the activity of the sample precipitated in the form of Y(COO) 2 is measured. The Sr yield coefficient is determined by 85 Sr tracer or by gravimetry. The test is applicable for the determination of 90 Sr contamination originating from fallout or from other sources in soil, when the concentration of 90 Sr is higher than 0.2-0.4 Bqg -1 (5-10 pCig -1 ). The error of the method is less than +-2% of the amount of the 90 Sr present. (Sz.J.)

    Tausworthe, R. C.

    1994-01-01

    The CRISP90 Software Design Analyzer System, an update of CRISP-80, is a set of programs forming a software design and documentation tool which supports top-down, hierarchic, modular, structured design and programming methodologies. The quality of a computer program can often be significantly influenced by the design medium in which the program is developed. The medium must foster the expression of the programmer's ideas easily and quickly, and it must permit flexible and facile alterations, additions, and deletions to these ideas as the design evolves. The CRISP90 software design analyzer system was developed to provide the PDL (Programmer Design Language) programmer with such a design medium. A program design using CRISP90 consists of short, English-like textual descriptions of data, interfaces, and procedures that are imbedded in a simple, structured, modular syntax. The display is formatted into two-dimensional, flowchart-like segments for a graphic presentation of the design. Together with a good interactive full-screen editor or word processor, the CRISP90 design analyzer becomes a powerful tool for the programmer. In addition to being a text formatter, the CRISP90 system prepares material that would be tedious and error prone to extract manually, such as a table of contents, module directory, structure (tier) chart, cross-references, and a statistics report on the characteristics of the design. Referenced modules are marked by schematic logic symbols to show conditional, iterative, and/or concurrent invocation in the program. A keyword usage profile can be generated automatically and glossary definitions inserted into the output documentation. Another feature is the capability to detect changes that were made between versions. Thus, "change-bars" can be placed in the output document along with a list of changed pages and a version history report. Also, items may be marked as "to be determined" and each will appear on a special table until the item is

  6. Hsp90 selectively modulates phenotype in vertebrate development.

    Full Text Available Compromised heat shock protein 90 (Hsp90 function reveals cryptic phenotypes in flies and plants. These observations were interpreted to suggest that this molecular stress-response chaperone has a capacity to buffer underlying genetic variation. Conversely, the protective role of Hsp90 could account for the variable penetrance or severity of some heritable developmental malformations in vertebrates. Using zebrafish as a model, we defined Hsp90 inhibitor levels that did not induce a heat shock response or perturb phenotype in wild-type strains. Under these conditions the severity of the recessive eye phenotype in sunrise, caused by a pax6b mutation, was increased, while in dreumes, caused by a sufu mutation, it was decreased. In another strain, a previously unobserved spectrum of severe structural eye malformations, reminiscent of anophthalmia, microphthalmia, and nanophthalmia complex in humans, was uncovered by this limited inhibition of Hsp90 function. Inbreeding of offspring from selected unaffected carrier parents led to significantly elevated malformation frequencies and revealed the oligogenic nature of this phenotype. Unlike in Drosophila, Hsp90 inhibition can decrease developmental stability in zebrafish, as indicated by increased asymmetric presentation of anophthalmia, microphthalmia, and nanophthalmia and sunrise phenotypes. Analysis of the sunrise pax6b mutation suggests a molecular mechanism for the buffering of mutations by Hsp90. The zebrafish studies imply that mild perturbation of Hsp90 function at critical developmental stages may underpin the variable penetrance and expressivity of many developmental anomalies where the interaction between genotype and environment plays a major role.

  7. Comparative effects of inhaled relatively insoluble forms of 90Y, 144Ce, and 90Sr on canine peripheral lymphocyte function

    Dogs that have inhaled relatively insoluble forms of either alpha- or beta-emitting radionuclides manifest a peripheral lymphopenia, the development and course of which depends on both total dose and dose rate. The remaining peripheral lymphocytes in dogs exposed to longer lived beta-emitting radionuclides showed a depressed function as measured by the ability to respond to plant mitogens in vitro. This experiment was designed to evaluate the effect of dose rate on peripheral lymphocyte function by exposing dogs to aerosols of radionuclides with varied effective half-lives in the lung: 90 Y (2.6 days), 144 Ce (170 days), and 90 Sr (650 days). Three groups of four adult beagle dogs each were exposed by inhalation to 90 Y, 144 Ce, or 90 Sr in fused-clay particles. Two controls were matched with each group. Initial lung burdens and initial dose rates to the lung were 520 to 610 μCi/kg of body weight and 2200 to 2600 rads/day in the 90 Y group, 33 to 60 μCi/kg and 200 to 350 rads/day in the 144 Ce group, and 25 to 32 μCi/kg and 130 to 170 rads/day in the 90 Sr group. Hematologic parameters and lymphocyte function as measured by the ability of lymphocytes to respond to plant mitogen stimulation were evaluated on a weekly or biweekly basis for 8 weeks after exposure and on a monthly basis thereafter. The 90 Y-exposed dogs showed a marked lymphopenia within 1 week with a return to control levels by 20 weeks after exposure. The remaining peripheral lymphocytes, however, showed no functional changes in these dogs. Animals exposed to 144 Ce or 90 Sr developed a progressive and persisent lymphopenia and showed functional depression of the remaining lymphocytes as well. The relationships among dose pattern, lymphopenia, and lymphocyte-function depression are discussed

    In this study, patients with affective disorders with or without suicide attempts were examined according to whether their disorder was unipolar or bipolar. An analysis was made of their socio-demographic variables, comorbid psychiatric symptoms, and affective temperament dimensions in order to understand the effects of these variables on suicide risk. The study populations consisted of 246 inpatients with affective disorders who had been admitted to the Erenköy Research and Training Hospital for Mental and Neurological Disorders (93 patients with unipolar disorders, 153 with bipolar disorders). The TEMPS-A (Temperament Evaluation of Memphis, Pisa, Paris and San Diego Auto-questionnaire), the Beck Hopelessness Scale (BHS) and the Symptom Checklist-90-Revised (SCL-90-R) psychological symptom screening tests were applied to all patients. In order to determine the affective disorder diagnosis and to identify suicide attempts, a Mini International Neuropsychiatric Interview (MINI) was performed during the first 48 hours of hospitalization. The cyclothymic and anxious temperament dimensions measured using TEMPS-A, somatic symptoms obtained from a symptom checklist, and psychiatric disorders in the family were found to be good indicators of suicide attempts in patients with unipolar disorders in this study. An investigation of predictors of suicide attempts in bipolar patients showed that cyclothymic temperament pattern, paranoid symptoms, evaluated through symptom screening test and having a psychiatric disorder in the family are good predictors of a suicide attempt. The findings are expected to guadiance to preventing suicide in patients with affective disorders. The inclusion in this study of patients with different index episodes of illness, including manic, depressive and mixed periods, can be accepted as a significant limitation of this study.

  10. BWR 90: The ABB advanced BWR design

    1999-01-01

    ABB has two evolutionary advanced fight water reactors available today - the BWR 90 boiling water reactor and the System 80+ pressurised water reactor. The BWR 90 is based on the design, construction, commissioning and operation of the BWR 75 plants. The operation experience of the six plants of this advanced design has been very good. The average annual energy availability is above 90%, and the total power generation costs have been low. In the development of BWR 90 specific changes were introduced to the reference design, to adapt to technological progress, new safety requirements and to achieve cost savings. The thermal power rating of BWR 90 is 3800 MWth (providing a nominal 1374 MWe net), slightly higher dim that of the reference plant ABB Atom has taken advantage of margins gained using a new generation of its SVEA fuel to attain this power rating without major design modifications. The BWR 90 design was completed and offered to the TVO utility in Finland in 1991, as one of the contenders for the fifth Finnish nuclear power plant project. Thus, the design is available today for deployment in new plant projects. Utility views were incorporated through co-operation with the Finnish utility TVO, owner and operator of the two Olkiluoto plants of BWR 75 design. A review against the European Utility Requirement (EUR) set of requirements has been performed, since the design, in 1997, was selected by the EUR Steering Committee to be the first BWR to be evaluated against the EUR documents. The work is scheduled for completion in 1998. It will be the subject of an 'EUR Volume 3 Subset for BWR 90' document. ABB is continuing its BWR development work with the 'evolutionary' design BWR 90+. The primary design goal is to develop the BWR as a competitive option for the anticipated revival of the market for new nuclear plants beyond the turn of the century, as well as feeding ideas and inputs to the continuous modernisation efforts at operating plants.

  12. Stontium-90 contamination in vegetation from radioactive waste seepage areas at ORNL, and theoretical calculations of /sup 90/Sr accumulation by deer

    Energy Technology Data Exchange (ETDEWEB)

    Garten, C.T. Jr.; Lomax, R.D.

    1987-06-01

    This report describes data obtained during a preliminary characterization of /sup 90/Sr levels in browse vegetation from the vicinity of seeps adjacent to ORNL solid waste storage areas (SWSA) where deer (Odocoileus virginianus) were suspected to accumulate /sup 90/Sr through the food chain. The highest strontium concentrations in plant samples were found at seeps associated with SWSA-5. Strontium-90 concentrations in honeysuckle and/or blackberry shoots from two seeps in SWSA-5 averaged 39 and 19 nCi/g dry weight (DW), respectively. The maximum concentration observed was 90 nCi/g DW. Strontium-90 concentrations in honeysuckle and blackberry shoots averaged 7.4 nCi/g DW in a study area south of SWSA-4, and averaged 1.0 nCi/g DW in fescue grass from a seepage area located on SWSA-4. A simple model (based on metabolic data for mule deer) has been used to describe the theoretical accumulation of /sup 90/Sr in bone of whitetail deer following ingestion of contaminated vegetation. These model calculations suggest that if 30 pCi /sup 90/Sr/g deer bone is to be the accepted screening level for retaining deer killed on the reservation, then 5-pCi /sup 90/Sr/g DW vegetation should be considered as a possible action level in making decisions about the need for remedial measures, because unrestricted access and full utilization of vegetation contaminated with <5 pCi/g DW results in calculated steady-state (maximum) /sup 90/Sr bone concentrations of <30 pCi/g in a 45-kg buck.

    Tests with actual ground water from Hanford site, and fundamental studies of 2Na + →Sr 2+ exchange equilibria revealed that a synthetic clay is extremely selective for 90 Sr with a high capacity for uptake. Comparative studies with existing Sr selective ion exchangers clearly revealed that the present synthetic clay exhibited the best performance for 90 Sr removal from actual ground water collected from three different locations at Hanford. This novel Sr ion sieve is expected to be useful for the decontamination of the environment after accidental release and contamination with 90 Sr. (c) 2000 Materials Research Society

    Introduction: 90 Y has shown satisfactory results in the therapy of multiple oncological diseases. This radionuclide has been widely used in therapy of diseases such as NHL (Zevalin), TNE ( 90 Y-DOTATOC), liver cancer, etc. Its safe and effective use presupposes the availability of accurate dosimetry methods and reproducible.El objective of this work is to standardize and optimize images use procedures that allow for dosimetric estimates braking during therapy of malignant diseases 90 Y. Materials and Methods: To quantify the activity in absolute units from scans correction methods that consider the peculiarities of the bremsstrahlung of 90 Y were proposed. acquisition parameters such as the selection of the collimator and the definition of energy windows as well as methods of scatter correction, attenuation, interactions of radiation with the collimator (septal penetration and degradation of information with distance) were considered and sensitivity or calibration factor was estimated. They were evaluated and calibrated parameters for dosimetry at the level of organ and estimates of distributions 3D dose, using experimental measurements with SPECT Mediso Nucline ™ Spirit DH-V system and simulations were performed using the Monte Carlo method, using the SIMIND v5 software .0. Results: The optimum position-energy window width and collimator to be used is determined from the relationship between total photons and primary photons (T / P), calculated with SIMIND. The results were favorable to employ HEGP collimator and energy window between 90-170kev. the sensitivity of the system for the selected collimator (HEGP for 90 Y) was estimated. He was evaluated and determined the MTF order to correct dispersive plane images, the source-detector and interactions of radiation with the collimator distance, using filtering methods (Wiener filter), including empirical estimates of the SNR component. Similarly the procedure for the use of transmission maps obtained from

    to describe whether there were differences in sociodemographic, obstetric, perinatal and psychological variables between immigrant women and native-born women in Spain during the first 24 h after delivery. The immediate postpartum period is a critical time when physical and psychological disorders are likely to occur. Immigrant women have, in general, poor perinatal and psychological results during this time. One hundred and three women at the Virgen de las Nieves University Hospital (Granada, Spain) were divided into two groups: 50 Spanish and 53 immigrants. The instruments used were the Life Orientation Test, the Stress Vulnerability Inventory, the Perceived Stress Scale and the Symptom Checklist-90-Revised (SCL-90-R). Sociodemographic and obstetric data were obtained from the healthcare providers reports. During the postpartum period, the immigrant women had higher mean scores on the following subscales: interpersonal sensitivity (F(1,102) = 4.06; p psychological and emotional support from their families, midwives and the rest of healthcare providers than are native Spaniards immediately after delivery.

    Sarmiento, J.L.; Gwinn, E.

    1986-01-01

    An empirical formula is developed for predicting monthly sea level strontium 90 fallout (F) in the northern hemisphere as a function of time (t), precipitation rate (P), latitude (phi), longitude (lambda), and the sea level concentration of stronium 90 in air (C): F(lambda, phi, t) = C(t, phi)[v /sub d/(phi) + v/sub w/(lambda, phi, t)], where v/sub w/(lambda, phi, t) = a(phi)[P(lambda, phi, t)/P/sub o/]/sup b//sup (//sup phi//sup )/ is the wet removal, v/sub d/(phi) is the dry removal and P 0 is 1 cm/month. The constants v/sub d/, a, and b are determined as functions of latitude by fitting land based observations. The concentration of 90 Sr in air is calculated as a function of the deseasonalized concentration at a reference latitude (C-bar/sub r//sub e//sub f/), the ratio of the observations at the latitude of interest to the reference latitude (R), and a function representing the seasonal trend in the air concentration (1 + g): C-bar(t, phi) = C/sub r//sub e//sub f/(t)R(phi)[1 + g(m, phi)]; m is the month. Zonal trends in C are shown to be relatively small. This formula can be used in conjuction with precipitation observations and/or estimates to predict fallout in the northern hemisphere for any month in the years 1954 to 1974. Error estimates are given; they do not include uncertainty due to errors in precipitation data

    Yttrium-90 is an important radionuclide known for its therapeutic application in nuclear medicine. It is a pure β-emitter with no associated gamma rays and decays to stable daughter 90 Zr. Suitability of this isotope is because of its short half-life (t 1/2 = 64.2 hrs) and high β emissions (E max = 2.28 MeV. An important source of 90 Y is through the decay of 90 Sr, which produces carrier free isotope. 90 Sr (t 1/2 28 yrs) attains secular equilibrium with 90 Y in a short period and can serve as a long term source for the latter isotope because of relatively long half-life of the parent isotope. Solvent extraction studies with N,N,N',N'-tetra-octyldiglycolamide (TODGA) has shown that Y(III) is well extracted in 6 M HCI while at the same time, extraction of Sr(II) is very low leading to a separation factor (D Y /D Sr = 60,000). This property of TODGA can be exploited for the separation of Y from Sr. In the present work, Supported Liquid Membrane (SLM) based separation of Y and Sr has been explored using TODGA as the carrier

    An anti-carcinoembryonic antigen (CEA) antibody, NP-4, was labeled with {sup 90}Y using p-isothiocyanatobenzyl DTPA (SCN-Bz-DTPA) and its derivatives 1-(p-isothiocyanatobenzyl)-3-methyl-DTPA (1B3M), 2-(p-isothiocyanatobenzyl)-4-methyl-DTPA (1M3B), 1-(2)-methyl-4-isothiocyanatobenzyl-DTPA (MX-DTPA) as the chelating agents. The {sup 90}Y conjugates were purified from unbound {sup 90}Y by two different methods, HPLC or acrylamide size exclusion gel chromatography, in order to evaluate the best purification method. Labeling efficiency, reaction kinetics and immunoreactivity were compared to the same antibodies labeled with ({sup 111}In)citrate. Labeling efficiency, as determined by either HPLC or ITLC (instant thin layer chromatography), was consistently higher by ITLC than HPLC for {sup 90}Y-labeled MAb, but equal for {sup 111}In-labeled MAbs. Discrepancies between the 2 methods were linked to impurities in the {sup 90}Y that remained at the origin of ITLC plates. After purification by acrylamide gel filtration, recovery was 50-60% of loaded {sup 90}Y activity, but was more than 87% for the {sup 111}In compounds. Using HPLC, the recovery measured 85% for {sup 90}Y-labeled MAb and more than 93% for {sup 111}In-labeled conjugates. Immunoreactivity of the ({sup 90}Y)MAb was comparable to the {sup 111}In-labeled conjugates. These studies indicate that HPLC purification of the ({sup 90}Y) MAbs improves recovery of activity, and suggests that impurities found in the {sup 90}Y and metal-binding properties of acrylamide may have contributed to the poor recoveries from acrylamide gels.

    Introduction: The scope of using no carrier added (NCA) 90 Y [T 1/2 = 64.1 h, E β(max) = 2.28 MeV] obtained from 90 Sr/ 90 Y generator in radiation synovectomy (RSV) is widely accepted. In the present study, the prospect of using 90 Y produced by (n,γ) route in a medium flux research reactor for use in RSV was explored. Methods: Yttrium-90 was produced by thermal neutron irradiation of Y 2 O 3 target at a neutron flux of ~ 1 × 10 14 n/cm 2 .s for 14 d. The influence of various experimental parameters were systematically investigated and optimized to arrive at the most favorable conditions for the formulation of 90 Y labeled hydroxyapatite (HA) using HA particles of 1–10 μm size range. An optimized kit formulation strategy was developed for convenient one-step compounding of 90 Y-HA, which is easily adaptable at hospital radiopharmacy. The pre-clinical biological evaluation of 90 Y-HA particles was studied by carrying out biodistribution and bioluminiscence imaging studies in Wistar rats. The first clinical investigation using the radiolabeled preparation was performed on a patient suffering from chronic arthritis in knee joint by administering 185 MBq 90 Y-HA formulated at the hospital radiopharmacy deploying the proposed strategy. Results: Yttrium-90 was produced with a specific activity of 851 ± 111 MBq/mg and radionuclidic purity of 99.95 ± 0.02%. 90 Y-labeled HA particles (185 ± 10 MBq doses) were formulated in high radiochemical purity (> 99%) and excellent in vitro stability. The preparation showed promising results in pre-clinical studies carried out in Wistar rats. The preliminary results of the first clinical investigation of 90 Y-HA preparation in a patient with rheumatoid arthritis in knee joints demonstrated the effectiveness of the formulation prepared using 90 Y produced via (n,γ) route in the management of the disease. Conclusion: The studies revealed that effective utilization of 90 Y produced via (n,γ) route in a medium flux research

    To assess self-perceived mental health in women treated with in vitro fertilisation (IVF) 20-23 years previously, while comparing them to a reference group, and to determine any differences in mental health between those who had given birth, those who had adopted a child, those who had given birth and adopted a child and those who remained childless. A cross-sectional study. A Center of Reproductive Medicine (RMC) at a Swedish University hospital. 520 women who had undergone at least one IVF cycle at the University Hospital in Linköping between 1986 and 1989. 504 of 520 women (97%) were eligible for follow-up. While 34 women declined, 93 per cent (n=470) of the women agreed to participate. The reference group consisted of 150 women of the Swedish population included in a study that was used to validate the Symptom CheckList (SCL)-90. Follow-up was conducted in 2008-2009. The SCL-90 was used to measure the women's self-perceived mental health and a questionnaire specific for this study was used to retain demographic information. The SCL-90 assesses 9 primary dimensions; somatisation, obsessive-compulsive, interpersonal sensitivity, depression, anxiety, hostility, phobic anxiety, paranoid ideation and psychoticism. There is also a global index of distress. Women who had previously undergone IVF treatment were at increased risk of symptoms of depression (p=0.017), obsessive-compulsion (p=0.02) and somatisation (p≤0.001) when compared to a reference group. In addition, the women who have remained childless are at increased risk of symptoms of depression (p=0.009) and phobic anxiety (p=0.017). The majority of the women who have been treated with IVF 20-23 years previously appear to be in good mental health. However, women who remain childless and/or without partner after unsuccessful infertility treatment constitute a vulnerable group even later on in life. Published by the BMJ Publishing Group Limited.

    Full Text Available BACKGROUND: In Germany, inpatient psychotherapy plays a unique role in the treatment of patients with common mental disorders of higher severity. In addition to psychiatric inpatient services, psychotherapeutic hospital treatment and psychosomatic rehabilitation are offered as independent inpatient treatment options. This meta-analysis aims to provide systematic evidence for psychotherapeutic hospital treatment in Germany regarding its effects on symptomatic and interpersonal impairment. METHODOLOGY: Relevant papers were identified by electronic database search and hand search. Randomized controlled trials as well as naturalistic prospective studies (including post-therapy and follow-up assessments evaluating psychotherapeutic hospital treatment of mentally ill adults in Germany were included. Outcomes were required to be quantified by either the Symptom-Checklist (SCL-90-R or short versions or the Inventory of Interpersonal Problems (IIP-64 or short versions. Effect sizes (Hedges' g were combined using random effect models. PRINCIPAL FINDINGS: Sixty-seven papers representing 59 studies fulfilled inclusion criteria. Meta-analysis yielded a medium within-group effect size for symptom change at discharge (g = 0.72; 95% CI 0.68-0.76, with a small reduction to follow-up (g = 0.61; 95% CI 0.55-0.68. Regarding interpersonal problems, a small effect size was found at discharge (g = 0.35; 95% CI 0.29-0.41, which increased to follow-up (g = 0.48; 95% CI 0.36-0.60. While higher impairment at intake was associated with a larger effect size in both measures, longer treatment duration was related to lower effect sizes in SCL GSI and to larger effect sizes in IIP Total. CONCLUSIONS: Psychotherapeutic hospital treatment may be considered an effective treatment. In accordance with Howard's phase model of psychotherapy outcome, the present study demonstrated that symptom distress changes more quickly and strongly than interpersonal problems.

    The aim of this study is to investigate the relationship between the risk of muscle dysmorphia and psychopathological symptoms in an Italian sample of male bodybuilders. The sample was recruited online (145 men with a mean age of 30.0 years) and participants were asked to fill out the Muscle Dysmorphic Disorder Inventory (MDDI), Symptom Cheklist-90-R (SCL-90-R), Dissociative Experiences Scale (DES-II), and to provide other socio-demographic data. Bodybuilders at risk of muscle dysmorphia display greater global psychopathology and present higher scores on all SCL-90-R dimensions when compared to bodybuilders not at risk of muscle dysmorphia. Furthermore, risk of muscle dysmorphia is positively associated to dissociative symptoms. The Competitiveness dimension and anabolic steroid intake were not related to muscle dysmorphia, while age appeared to be more significant. Findings are discussed based upon previous studies and directions for future research are suggested. Copyright © 2017 Elsevier B.V. All rights reserved.

    Radioimmunotherapy (RIT) with 90Y-labeled immunoconjugates has shown promise in clinical trials. The macrocyclic chelating agent 1,4,7,10-tetraazacyclododecane-N,N',N",N"'-tetraacetic acid (DOTA) binds 90Y with extraordinary stability, minimizing the toxicity of 90Y-DOTA immunoconjugates arising from loss of 90Y to bone. However, reported 90Y-DOTA immunoconjugate product yields have been typically only BAD) was conjugated to the monoclonal antibody Lym-1 via 2-iminothiolane (2IT). The immunoconjugate product, 2IT-BAD-Lym-1, was labeled in excess yttrium in various buffers over a range of concentrations and pH. Kinetic studies were performed in selected buffers to estimate radiolabeling reaction times under prospective radiopharmacy labeling conditions. The effect of temperature on reaction kinetics was examined. Optimal radiolabeling conditions were identified and used in eight radiolabeling experiments with 2IT-BAD-Lym-1 and a second immunoconjugate, DOTA-peptide-chimeric L6, with 248-492 MBq (6.7-13.3 mCi) of 90Y. Ammonium acetate buffer (0.5 M) was associated with the highest uptake of yttrium. On the basis of kinetic data, the time required to chelate 94% of 90Y (four half-times) under prospective radiopharmacy labeling conditions in 0.5 M ammonium acetate was 17-148 min at pH 6.5, but it was only 1-10 min at pH 7.5. Raising the reaction temperature from 25 degrees C to 37 degrees C markedly increased the chelation rate. Optimal radiolabeling conditions were identified as: 30-min reaction time, 0.5 M ammonium acetate buffer, pH 7-7.5 and 37 degrees C. In eight labeling experiments under optimal conditions, a mean product yield (+/- s.d.) of 91%+/-8% was achieved, comparable to iodination yields. The specific activity of final products was 74-130 MBq (2.0-3.5 mCi) of 90Y per mg of monoclonal antibody. The immunoreactivity of 90Y-labeled immunoconjugates was 100%+/-11%. The optimization of 90Y-DOTA chelation conditions represents an important advance in 90Y RIT

    Purpose: To investigate 90 Sr- 90 Y as a high dose rate (HDR) source for application in a conformal skin brachytherapy (CSBT) device. The CSBT device has been previously developed to provide patient specific treatment for small inoperable lesions and irregular surfaces. Methods: A popular beta emitter, 90 Sr- 90 Y was tested for feasibility in a CSBT device. A 1 cm diameter plaque was used to deliver dose to a solid water phantom containing EBT3 Gafchromic films arranged at the surface and perpendicular to it. Additionally, a 1 cm diameter 6 MeV electron beam was used to irradiate EBT3 film at 100 cm SSD with a 0.5 cm bolus. Films were digitized with an Epson Expression 10000 XL scanner and calibrated with a 6 MeV electron specific dose curve. Normalized percent depth doses (PDD) and dose profiles for both techniques were analyzed using ImageJ. Results: Dose distributions achieved with the 90 Sr- 90 Y sources were compared with those of external electron beam radiation therapy (EBRT). Penumbra (20%- 80%) for EBRT and 90Sr-90Y were 4.3 mm and 1.6 mm, respectively. PDD values of 50% (normalized to 2 mm) were 10.1 mm and 2.8 mm for electron and 90 Sr- 90 Y, respectively. Flatness (80% of the central beam profile) was 14.1% at a 5 mm depth for EBRT and 4.0% at surface for the 90 Sr- 90 Y. Conclusion: As expected, the PDDs of 90 Sr- 90 Y in water are shallower than that of external electron beams for the same field size. 90 Sr- 90 Y can be used in CSBT to provide patient specific treatment where shallower depth doses than that provided by electron external beams may be required: e.g. eyelids, nose, lips, ears, etc. The customizability of EBRT could be replicated by using multiple adjacent 90 Sr- 90 Y plaque placements.

    The experiment feeding 90 Sr(NO 3 ) 2 in the range of 1.85 x 10 2 to 1.85 x 10 5 Bq/chicken was carried out with 45 Beijing-white layers to observe the regular pattern of absorption and distribution of 90 Sr in organs and tissues. The results are summarized as follows: the uptake rate of 90 Sr by layer through oral feeding is very low. Most part of 90 Sr drains away from body with daily excreta and egg. The accumulation of 90 Sr in the body is low and about 70% is in the bone. About 99% of 90 Sr in egg is concentrated in the eggshell. The order of absorptivity of 90 Sr in tissues is bone>feather>muscle>blood>viscera. The absorption coefficient of 90 Sr in organs and tissues in different stages with different feeding volumes has been calculated

    Current research on Internet addiction (IA) reported moderate to high prevalence rates of IA and comorbid psychiatric symptoms in users of social networking sites (SNS) and online role-playing games. The aim of this study was to characterize adult users of an Internet multiplayer strategy game within a SNS. Therefore, we conducted an exploratory study using an online survey to assess sociodemographic variables, psychopathology, and the rate of IA in a sample of adult social network gamers by Young's Internet Addiction Test (IAT), the Toronto Alexithymia Scale (TAS-26), the Beck Depression Inventory-II (BDI-II), the Symptom Checklist-90-R (SCL-90-R), and the WHO Quality of Life-BREF (WHOQOL-BREF). All participants were listed gamers of "Combat Zone" in the SNS "Facebook." In this sample, 16.2% of the participants were categorized as subjects with IA and 19.5% fulfilled the criteria for alexithymia. Comparing study participants with and without IA, the IA group had significantly more subjects with alexithymia, reported more depressive symptoms, and showed poorer quality of life. These findings suggest that social network gaming might also be associated with maladaptive patterns of Internet use. Furthermore, a relationship between IA, alexithymia, and depressive symptoms was found that needs to be elucidated by future studies.

    Full Text Available Heat shock protein 90 (HSP90 represents a suite of highly conserved and multi-functional molecular chaperone proteins that play an important role in cellular stress responses. In order to better understand the expression of HSP90 in mollusks, a full-length complementary DNA (cDNA of HSP90 (HcHSP90 was identified in Hyriopsis cumingii. HcHSP90 cDNA was 2659 bp in length, consisting of 3′ and 5′-untranslated regions and an open reading frame of 2187 bp, that encoded a 728 amino acid protein. Homology analyses showed that the HcHSP90 protein was highly conserved and had 5 well-conserved family signatures of HSP90 proteins. HcHSP90 mRNA expressed in various tissues of H. cumingii. The expression level of HcHSP90 was the highest in the digestive gland. In all tissues, with the exception of the digestive gland where it was down-regulated, HcHSP90 mRNA expression was significantly induced by temperature treatments (0, 5, 25, and 35 °C relative to the control (15 °C. Exposure of H. cumingii to different concentrations of cadmium (50, 100, and 200 μg/L, up-regulated HcHSP90 mRNA in the haemolymph and gill but without an obvious dose-dependent response. When H. cumingii were infected with Aeromonas hydrophila, HcHSP90 mRNA expression in the haemolymph was up-regulated and peaked 36 h post-infection, while in the gills it was significantly up-regulated 3 h post-infection in the gills, then remained constant until returning to pre-challenge expression levels at 36 h post-infection. The results show that HcHSP90 expression can be significantly regulated by changes in temperature, cadmium exposure and bacterial infection. We deduced that HSP90 may play an important role in helping H. cumingii to cope with environmental stress.

    Parish, T.A.

    1979-01-01

    Transmutation of 90 Sr using fusion neutrons has been suggested as a possible technique for disposing of this waste nuclide. For transmutation to be attractive, high transmutation rates relative to natural decay are required. Effective half-lives for 90 Sr were computed for fusion reactor blankets constructed of various materials. To obtain satisfactory transmutation rates, fusion reactors with high first wall neutron currents and with highly moderating blankets were found to be necessary. An effective half-life for 90 Sr of 90 Sr inventory and the number of burners required for various fission usage scenarios. Efficient and fast chemical separations were needed to reap the benefits of a short effective half-life. For the fusion burners considered, it was found that the 90 Sr inventory could not be reduced to less than one-fourth of the inventory without transmutation if fission usage continued at a constant rate. Such a reduction is not sufficient to justify the transmutation disposal of 90 Sr

    2008-08-01

    The Candida albicans heat shock protein 90 kDa (hsp90-CA) is an important target for protective antibodies in disseminated candidiasis of experimental mice and humans. Hsp90-CA is present in the cell wall of Candida pseudohyphae or hyphae--typical pathogenic morphotypes in both mucosal and systemic Candida infections. However, the potential protective effects of hsp90-CA-specific antibodies in vaginal candidiasis has not yet been reported. In the present study we used various vaccine formulations (recombinant hsp90-CA protein and hsp90-CA-encoding DNA vaccine) and routes of administration (intradermal, intranasal, and intravenous) to induce both hsp90-CA-specific systemic and vaginal mucosa immune responses in experimental BALB/c mice. The results showed that intradermal recombinant hsp90-CA protein priming, followed by intranasal or intradermal recombinant hsp90-CA protein boosting induced significant increases in both serum and vaginal hsp90-CA-specific IgG and IgA antibodies compared to the control group, as well as enhanced hsp90-CA-specific splenocyte responses in vitro. In the intradermally boosted group, subsequent experimental vaginal Candida infection induced additional increases in the hsp90-CA specific IgG isotype, suggesting that Candida has the ability to induce a local hsp90-specific antibody (IgG) response during vulvovaginal candidiasis. Further work is required to elucidate the importance of immunity to highly conserved antigens during infection of the human female reproductive tract where a balance between immunity to and tolerance for commonly antigens such as hsp90 is necessary for the maintenance of fertility.

    Developed was a simple and selective chromatographic method of the separation of strontium-90, by the content of which it is possible to judge about the degree of nuclear fuel burnup. Among the studied ion exchangers for strontium separation the best results are exhibited by strongly acidic organic cationite, i.e. vofatite (on the base of styrene, 8%-divinylbenzene) in the H + form. Elution was performed by hydrochloric or oxalic acids. The method allows to achieve a high degree of Sr-90 purification from other fission products. Using the method the Sr-90 content was determined in burnup fuel of the fuel elements of EK-10 type. At the fuel storage period less than 2 years it becomes necessary to determine both Sr-90 and Sr-89. Determination of Sr-90 in the presence of Sr-89 was made by daughter product of Sr-90 - Y-90, which is separated in ion-exchange coloumn. Some other methods of Sr-90 determination in the presence of Sr-89 are noted

    Sym-Dibenzo-16-crown-5-oxyacetic acid and its analogues are selective for the extraction of Y 3+ over Sr 2+ from aqueous solutions into chloroform. The selectivity and the pH range of extraction are influenced by the structure of the ligand. The size of the macrocyclic cavity, the tether length of the lariat, the attachment of alkyl functional groups to the lariat, and the identity of the ionizable group can affect selectivity and extraction efficiency. When the carboxylic acid at the terminal end of the lariat is replaced by a hydroxamic acid, the selectivity for Y 3+ over Sr 2+ is significantly increased. Using these ionizable crown ethers as extractants, 90 Y fractions of greater than 99.9% purity can be obtained in a single solvent extraction step from solutions of 90 Sr. 11 refs., 5 figs., 2 tabs

    In this paper the inventory of {sup 90}Sr in 34 points distributed along the Spanish peninsular territory is presented. Obtained values range between 173 Bq/m{sup 2} and 2047 Bq/m{sup 2}. From these data set and those {sup 137}Cs data obtained in a previous work the {sup 137}Cs/{sup 90}Sr activity ratio has been established, laying this value between 0.9 and 3.6. Also the migration depth of both radionuclides has been analysed obtaining for {sup 137}Cs an average value 57% lower than that obtained for {sup 90}Sr. Additionally, this paper presents the results obtained in 11 sampling points in which the activity vertical profile has been measured. These profiles have been analysed to state the behaviour of strontium in soils and after, by using a convective-diffusive model, the parameters of the model which governs the vertical migration of {sup 90}Sr in the soil, v (apparent convection velocity) and D (apparent diffusion coefficient) have been evaluated. Mean values obtained are 0.20 cm/year and 3.67 cm{sup 2}/year, respectively. - Highlights: > Measured {sup 90}Sr activity in Spanish mainland, being within a range of [173, 2047] Bq/m{sup 2}, with a mean value of 793 Bq/m{sup 2}. > Compared the migration capacity of {sup 137}Cs and {sup 90}Sr in the same soils. > {sup 90}Sr shows a unique behaviour tendency in soil. > The parameters which govern the applied model have been obtained for the analysed profiles. > Analysed those parameters' values also reflects this unique tendency.

    Heat shock protein 90 (Hsp90) overexpression has been implicated in breast carcinogenesis, with putative prognostic and therapeutic implications. The purpose of this study is to evaluate the immunohistochemical expression of Hsp90 and to examine whether Hsp90 expression is associated with estrogen receptor alpha (ER-alpha) and beta (ER-beta) immunostaining in lobular neoplasia (LN) of the breast. Tissue specimens were taken from 44 patients with LN. Immunohistochemical assessment of Hsp90, ER-alpha and ER-beta was performed both in the lesion and the adjacent normal breast ducts and lobules; the latter serving as control. As far as Hsp90 evaluation is concerned: i) the percentage of positive cells, and ii) the intensity was separately analyzed. Additionally, the Allred score was adopted and calculated. Accordingly, Allred score was separately evaluated for ER-alpha and ER-beta. The intensity was treated as an ordinal variable-score (0: negative, low: 1, moderate: 2, high: 3). Statistical analysis followed. Hsp90 immunoreactivity was mainly cytoplasmic in both the epithelial cells of normal breast (ducts and lobules) and LN. Some epithelial cells of LN also showed nuclear staining, but all the LN foci mainly disclosed a positive cytoplasmic immunoreaction for Hsp90. In addition, rare intralobular inflammatory cells showed a slight immunoreaction. The percentage of Hsp90 positive cells in the LN areas was equal to 67.1 ± 12.2%, whereas the respective percentage in the normal adjacent breast tissue was 69.1 ± 11.6%; the difference was not statistically significant. The intensity score of Hsp90 staining was 1.82 ± 0.72 in LN foci, while in the normal adjacent tissue the intensity score was 2.14 ± 0.64. This difference was statistically significant (p = 0.029, Wilcoxon matched-pairs signed-ranks test). The Hsp90 Allred score was 6.46 ± 1.14 in the LN foci, significantly lower than in the normal adjacent tissue (6.91 ± 0.92, p = 0.049, Wilcoxon matched-pairs signed

    Despite significant gains in access to early infant diagnosis (EID) over the past decade, most HIV-exposed infants still do not get tested for HIV in the first two months of life. For those who are tested, the long turnaround time between when the sample is drawn and when the results are returned leads to a high rate of loss to follow-up, which in turn means that few infected infants start antiretroviral treatment. Consequently, there continues to be high mortality from perinatally acquired HIV, and the ambitious goals of 90% of infected children identified, 90% of identified children treated and 90% of treated children with sustained virologic suppression by 2020 seem far beyond our reach. The objective of this commentary is to review recent advances in the field of HIV diagnosis in infants and describe how these advances may overcome long-standing barriers to access to testing and treatment. Several innovative approaches to EID have recently been described. These include point-of-care testing, use of SMS printers to connect the central laboratory and the health facility through a mobile phone network, expanding paediatric testing to other entry points where children access the health system and testing HIV-exposed infants at birth as a rapid way to identify in utero infection. Each of these interventions is discussed here, together with the opportunities and challenges associated with scale-up. Point-of-care testing has the potential to provide immediate results but is less cost-effective in settings where test volumes are low. Virological testing at birth has been piloted in some countries to identify those infants who need urgent treatment, but a negative test at birth does not obviate the need for additional testing at six weeks. Routine testing of infants in child health settings is a useful strategy to identify exposed and infected children whose mothers were not enrolled in programmes for the prevention of mother-to-child transmission.

    Mind-body medical approaches may ameliorate chronic disease. Stress reduction is particularly helpful, but face-to-face delivery systems cannot reach all those who might benefit. An online, 3-dimensional virtual world may be able to support the rich interpersonal interactions required of this approach. In this pilot study, we explore the feasibility of translating a face-to-face stress reduction program into an online virtual setting and estimate the effect size of the intervention. Domain experts in virtual world technology joined with mind body practitioners to translate an existing 8 week relaxation response-based resiliency program into an 8-week virtual world-based program in Second Life™ (SL). Twenty-four healthy volunteers with at least one month's experience in SL completed the program. Each subject filled out the Perceived Stress Scale (PSS) and the Symptom Checklist 90- Revised (SCL-90-R) before and after taking part. Participants took part in one of 3 groups of about 10 subjects. The participants found the program to be helpful and enjoyable. Many reported that the virtual environment was an excellent substitute for the preferred face-to-face approach. On quantitative measures, there was a general trend toward decreased perceived stress, (15.7 to 15.0), symptoms of depression, (57.6 to 57.0) and anxiety (56.8 to 54.8). There was a significant decrease of 2.8 points on the SCL-90-R Global Severity Index (pmind-body medical intervention through a virtual environment and that it is well received. Moreover, the small reduction in psychological distress suggests further research is warranted.

    Full Text Available The International Classification of Diseases, 10th edition (ICD-10 defines atypical bulimia nervosa (ABN as an eating disorder that encompasses several different syndromes, including the DSM-IV binge eating disorder (BED. We investigated whether patients with BED can be differentiated clinically from patients with ABN who do not meet criteria for BED. Fifty-three obese patients were examined using the Structured Clinical Interview for DSM-IV and the ICD-10 criteria for eating disorders. All volunteers completed the Binge Eating Scale (BES, the Beck Depression Inventory, and the Symptom Checklist-90 (SCL-90. Individuals fulfilling criteria for both ABN and BED (N = 18, ABN without BED (N = 16, and obese controls (N = 19 were compared and contrasted. Patients with ABN and BED and patients with ABN without BED displayed similar levels of binge eating severity according to the BES (31.05 ± 7.7 and 30.05 ± 5.5, respectively, which were significantly higher than those found in the obese controls (18.32 ± 8.7; P < 0.001 and P < 0.001, respectively. When compared to patients with ABN and BED, patients with ABN without BED showed increased lifetime rates of agoraphobia (P = 0.02 and increased scores in the somatization (1.97 ± 0.85 vs 1.02 ± 0.68; P = 0.001, obsessive-compulsive (2.10 ± 1.03 vs 1.22 ± 0.88; P = 0.01, anxiety (1.70 ± 0.82 vs 1.02 ± 0.72; P = 0.02, anger (1.41 ± 1.03 vs 0.59 ± 0.54; P = 0.005 and psychoticism (1.49 ± 0.93 vs 0.75 ± 0.55; P = 0.01 dimensions of the SCL-90. The BED construct may represent a subgroup of ABN with less comorbities and associated symptoms.

    Accelerator mass spectrometry (AMS) is one of method used for {sup 90}Sr determination. It would enable rapid {sup 90}Sr measurements from environmental samples such as water, soil, and milk. However, routine analysis of {sup 90}Sr using AMS has not yet been achieved because of difficulties associated with isobaric separation and production of intense negative ion beams characterized by currents from hundreds of nanoamperes to several microamperes. We have developed a rapid procedure for preparing samples with optimum compositions for use with AMS, which enables production of intense Sr beam currents from an ion source. Samples of SrF{sub 2} were prepared from a standard Sr solution and agricultural soil. The time required to prepare a SrF{sub 2} sample from a soil sample was 10 h. Negative {sup 88}SrF{sub 3}{sup −} ions were successfully extracted at 500 nA from mixed samples of SrF{sub 2} and PbF{sub 2}. In the present work, negative ions of {sup 90}Zr, included as an impurity, were accelerated with a tandem accelerator operated at a terminal voltage of 5 MV. Ions characterized by a charge state of 6+ were channeled into a gas counter. An atomic ratio of {sup 90}Zr/{sup 88}Sr of 3 × 10{sup −8} was estimated for the soil sample. No signal was detected from the assay of PbF{sub 2}, which was pressed in an aluminum cathode, for a mass number of 90. PbF{sub 2} revealed good performance in the production of negative SrF{sub 3}{sup −} molecular ion beams and detection of {sup 90}Sr with a gas counter.

    A radiochemical method for the determination of 90 Sr in non-contaminated grass and soil is presented. The method is based on the leaching of 90 Sr from the mineralized samples followed by liquid-liquid extraction of 90 Y, its short lived daughter, by tributylphosphate and precipitation of Y-oxalate, which is counted in a low-level proportional counter. Based on dried samples of 30 g of soil and 100 g of grass the limit of detection is about 0.1 Bq/kg for both materials. (author) figs., tabs., 43 refs

    One function of the glucocorticoid receptor (GR) in corticotroph cells is to suppress the transcription of the gene encoding proopiomelanocortin (POMC), the precursor of the stress hormone adrenocorticotropin (ACTH). Cushing disease is a neuroendocrine condition caused by partially glucocorticoid-resistant corticotroph adenomas that excessively secrete ACTH, which leads to hypercortisolism. Mutations that impair GR function explain glucocorticoid resistance only in sporadic cases. However, the proper folding of GR depends on direct interactions with the chaperone heat shock protein 90 (HSP90, refs. 7,8). We show here that corticotroph adenomas overexpress HSP90 compared to the normal pituitary. N- and C-terminal HSP90 inhibitors act at different steps of the HSP90 catalytic cycle to regulate corticotroph cell proliferation and GR transcriptional activity. C-terminal inhibitors cause the release of mature GR from HSP90, which promotes its exit from the chaperone cycle and potentiates its transcriptional activity in a corticotroph cell line and in primary cultures of human corticotroph adenomas. In an allograft mouse model, the C-terminal HSP90 inhibitor silibinin showed anti-tumorigenic effects, partially reverted hormonal alterations, and alleviated symptoms of Cushing disease. These results suggest that the pathogenesis of Cushing disease caused by overexpression of heat shock proteins and consequently misregulated GR sensitivity may be overcome pharmacologically with an appropriate HSP90 inhibitor.

    A good irradiation geometry was achieved in order to carry out the irradiation of an essential eucalyptus oil with a 90 Y/ 90 Sr electron source. The Monte Carlo simulation code MCNP-4C was employed to determine the absorbed doses in this particular experimental configuration. It also helped us to understand which electrons (from an energetic point of view) were responsible for the damages. In order to identify the induced damages, the irradiated samples were studied by mass spectrometry. The obtained results were related to the absorbed doses determined by the computational simulation

  14. Exploring the Functional Complementation between Grp94 and Hsp90.

    Directory of Open Access Journals (Sweden)

    Kevin A Maharaj

    Full Text Available Grp94 and Hsp90 are the ER and cytoplasmic paralog members, respectively, of the hsp90 family of molecular chaperones. The structural and biochemical differences between Hsp90 and Grp94 that allow each paralog to efficiently chaperone its particular set of clients are poorly understood. The two paralogs exhibit a high degree of sequence similarity, yet also display significant differences in their quaternary conformations and ATPase activity. In order to identify the structural elements that distinguish Grp94 from Hsp90, we characterized the similarities and differences between the two proteins by testing the ability of Hsp90/Grp94 chimeras to functionally substitute for the wild-type chaperones in vivo. We show that the N-terminal domain or the combination of the second lobe of the Middle domain plus the C-terminal domain of Grp94 can functionally substitute for their yeast Hsp90 counterparts but that the equivalent Hsp90 domains cannot functionally replace their counterparts in Grp94. These results also identify the interface between the Middle and C-terminal domains as an important structural unit within the Hsp90 family.

    Depression and anxiety are routinely screened as part of perinatal care. However, other Axis 1 disorders and specific anxiety disorders are less likely to be screened or assessed as part of obstetric care. The objective of this study was to determine whether the Psychiatric Diagnostic Screening Questionnaire (PDSQ) is a potentially useful tool to screen for psychiatric conditions in pregnant and postpartum women in a community setting. We compared the prevalence of DSM Axis I disorders obtained on the PDSQ with: (1) the prevalence of these disorders reported in previous studies of pregnant and postpartum women, and (2) scores obtained on the Edinburgh Postpartum Depression Scale (EPDS) and the Symptom Checklist-90-Revised (SCL-90R) anxiety scale. Data were obtained from the Alberta Pregnancy Outcomes and Nutrition (APrON) study. The PDSQ was completed by 1575 women prenatally and 1481 postnatally. The three most prevalent PDSQ conditions were social phobia, somatic disorder, and obsessive-compulsive disorder (OCD). The prevalence of social phobia, alcohol disorder, OCD and psychosis were higher in the APrON cohort compared with statistics in the literature. The proportion of women meeting depression and anxiety cut-offs on the PDSQ were lower than for the EPDS and the SCL-90R. The Cohens Kappa index ( k) indicated poor to fair agreement between the measures in classifying pregnant women as depressed or anxious. The PDSQ subscales may not be appropriate for the pregnant population. Research into instruments more specific to pregnant and postpartum women are needed to determine the prevalence of psychiatric disorders in this population.

    Objective: Stress perception depends on cultural and social aspects that vary from one country to another. One of the most widely disseminated methods of assessing psychological stress is the Perceived Stress Scale (PSS-4). Therefore, in order to identify these factors and their impact on mental health, the present study compares the PSS-4 results among three European countries (Great Britain, France and Spain). This study focuses on PSS-4 results within a Spanish sample to determine: (1) normative data, reliability and validity of PSS-4 in a Spanish sample and (2) how stress perception changes depending on cultural and social factors. Methods: The data were obtained from a website representing a service of a smoking cessation program, the study represented a service that was open to all individuals. The number of participants were 37,451. They reported their age, gender, nationality, marital status, education and employment status, and completed two psychological questionnaires (PPS-4 and the anxiety and depression scales of the Symptom Checklist-90-Revised, SCL 90-R). Results: The PSS-4 scores could differentiate between relevant sociodemographic variables (such as sex, age, nationality, marital status, education, parental status, employment status, and income class). The PSS-4 scores showed a positive correlation with the SCL 90-R anxiety and depression scales. The normed values for interpreting the PSS-4 scores are presented. The PSS-4 showed adequate internal consistency and reliability. Conclusions: The PSS-4 is a useful instrument for assessing stress perception levels in the general population in different countries. Its internal consistency is sufficient for a 4-item scale.

    Full Text Available Abstract Background Heat shock protein 90 (Hsp90 overexpression has been implicated in breast carcinogenesis, with putative prognostic and therapeutic implications. The purpose of this study is to evaluate the immunohistochemical expression of Hsp90 and to examine whether Hsp90 expression is associated with estrogen receptor alpha (ER-alpha and beta (ER-beta immunostaining in lobular neoplasia (LN of the breast. Methods Tissue specimens were taken from 44 patients with LN. Immunohistochemical assessment of Hsp90, ER-alpha and ER-beta was performed both in the lesion and the adjacent normal breast ducts and lobules; the latter serving as control. As far as Hsp90 evaluation is concerned: i the percentage of positive cells, and ii the intensity was separately analyzed. Additionally, the Allred score was adopted and calculated. Accordingly, Allred score was separately evaluated for ER-alpha and ER-beta. The intensity was treated as an ordinal variable-score (0: negative, low: 1, moderate: 2, high: 3. Statistical analysis followed. Results Hsp90 immunoreactivity was mainly cytoplasmic in both the epithelial cells of normal breast (ducts and lobules and LN. Some epithelial cells of LN also showed nuclear staining, but all the LN foci mainly disclosed a positive cytoplasmic immunoreaction for Hsp90. In addition, rare intralobular inflammatory cells showed a slight immunoreaction. The percentage of Hsp90 positive cells in the LN areas was equal to 67.1 ± 12.2%, whereas the respective percentage in the normal adjacent breast tissue was 69.1 ± 11.6%; the difference was not statistically significant. The intensity score of Hsp90 staining was 1.82 ± 0.72 in LN foci, while in the normal adjacent tissue the intensity score was 2.14 ± 0.64. This difference was statistically significant (p = 0.029, Wilcoxon matched-pairs signed-ranks test. The Hsp90 Allred score was 6.46 ± 1.14 in the LN foci, significantly lower than in the normal adjacent tissue (6.91

    (99m)Tc macroaggregate albumin (MAA) scintigraphy is routinely used to estimate the hepatopulmonary shunt (HPS) of (90)Y microspheres because of their comparable average particle sizes (20-30 µm). However, the MAA particle size can vary from 10 to 90 µm. Therefore, HPS computed from (99m)Tc MAA scintigraphy may not accurately represent the HPS of (90)Y microspheres. In view of this, the present study was undertaken to investigate the accuracy of (99m)Tc MAA scintigraphy in estimating the HPS of (90)Y microspheres. Nineteen sessions of transarterial radioembolization using (90)Y therasphere were carried out in 17 patients for hepatic malignancies (both primary and secondary). For each session of therapy, a pretherapeutic (99m)Tc MAA scintigraphy and post-therapeutic (90)Y Bremsstrahlung scintigraphy were performed. The HPSs obtained from these images were compared. The mean HPS fractions calculated from the pretherapeutic (99m)Tc MAA study and the post-therapeutic (90)Y Bremsstrahlung images were 4.77 ± 2.81 and 4.52 ± 2.5%, respectively. The coefficient of correlation (r) was 0.96. (99m)Tc MAA scintigraphy accurately predicts the HPS of (90)Y microspheres.

    About 70% of radioactive substances fell on the territory of the Byelorussian Republic after the Chernobyl Atom Power Station Disaster. Cs-137 and Sr-90 accumulation dynamics was studied in milk of the cows from the highest polluted Braginsky area. 408 milk samples of Black and White cows were investigated. In 1995 average Cs-137 and Sr-90 levels were 61.00 and 3.73 Bk/dm 3 respectively. Cs-137 and Sr-90 levels exceeded Byelorussian Republic upper limits RDU - 96 in 10 and 50% of milk samples respectively. After 5 years (by 2000) Cs-137 and Sr-90 levels had become almost 3 and 2 times less (21.70 Bk/dm 3 and 1.72 Bk/dm 3 respectively). Cs-137 and Sr-90 levels exceeded RDU - 96 in 1.5 and 5.5% of milk samples respectively. In the same periods Cs-137 and Sr-90 levels were 7 and 2 times higher than the similar indexes in the relatively clean Novosibirsk area. Thus, radioactive element levels in milk of Black and White cows of the Byelorussian Republic decreased significantly for the past years. (authors)

  6. Hsp90: A New Player in DNA Repair?

    Directory of Open Access Journals (Sweden)

    Rosa Pennisi

    2015-10-01

    Full Text Available Heat shock protein 90 (Hsp90 is an evolutionary conserved molecular chaperone that, together with Hsp70 and co-chaperones makes up the Hsp90 chaperone machinery, stabilizing and activating more than 200 proteins, involved in protein homeostasis (i.e., proteostasis, transcriptional regulation, chromatin remodeling, and DNA repair. Cells respond to DNA damage by activating complex DNA damage response (DDR pathways that include: (i cell cycle arrest; (ii transcriptional and post-translational activation of a subset of genes, including those associated with DNA repair; and (iii triggering of programmed cell death. The efficacy of the DDR pathways is influenced by the nuclear levels of DNA repair proteins, which are regulated by balancing between protein synthesis and degradation as well as by nuclear import and export. The inability to respond properly to either DNA damage or to DNA repair leads to genetic instability, which in turn may enhance the rate of cancer development. Multiple components of the DNA double strand breaks repair machinery, including BRCA1, BRCA2, CHK1, DNA-PKcs, FANCA, and the MRE11/RAD50/NBN complex, have been described to be client proteins of Hsp90, which acts as a regulator of the diverse DDR pathways. Inhibition of Hsp90 actions leads to the altered localization and stabilization of DDR proteins after DNA damage and may represent a cell-specific and tumor-selective radiosensibilizer. Here, the role of Hsp90-dependent molecular mechanisms involved in cancer onset and in the maintenance of the genome integrity is discussed and highlighted.

  7. Long-term impact of battle injuries; five-year follow-up of injured Dutch servicemen in Afghanistan 2006-2010.

    Full Text Available OBJECTIVES: Units deployed to armed conflicts are at high risk for exposure to combat events. Many battle casualties (BCs have been reported in the recent deployment to Afghanistan. The long-term impact of these combat injuries, at their five-year end point, is currently unknown. To date, no systematic inventory has been performed of an identified group of BCs in comparison to non-injured service members from the same operational theatre. DESIGN: Observational cross-sectional cohort study. SETTING: Open online survey among Dutch BCs that deployed to Afghanistan (2006-2010. PARTICIPANTS: The Dutch BCs (n = 62 were compared to two control groups of non-injured combat groups (battle exposed [n = 53], and non-battle exposed [n = 73]. MAIN OUTCOME MEASURES: Participants rated their impact of trauma exposure (Impact of Events [IES], post deployment reintegration (Post Deployment Reintegration Scale [PDRS], general symptoms of distress (Symptom Checklist 90 [SCL-90], as well as their current perceived quality of life (EuroQol-6D [EQ-6D]. Also cost effectiveness (Short From health survey [SF-36] and care consumption were assessed (Trimbos/iMTA questionnaire. RESULTS: Over 90% of BCs were still in active duty. The mean scores of all questionnaires (IES, EQ-6D, SF-36, and SCL-90 of the BC group were significantly higher than in the control groups (p<0.05. The PDRS showed a significantly lower (p<0.05 outcome in the negative subscales. The mean consumption of care was triple that of both control groups. A lower score on quality of life was related to higher levels of distress and impact of trauma exposure. CONCLUSIONS: This study showed a clear long-term impact on a wide range of scales that contributes to a reduced quality of life in a group of BCs. Low perceived cost effectiveness matched with high consumption of care in the BC group in comparison to the control groups. These results warrant continuous monitoring of BCs.

    In 33 patients with chronic arthritis of the knee, 48 knees were treated with an intra-articular injection of 5 mCi yttrium silicate 90 Y. There were 27 patients with rheumatoid arthritis (RA) and 6 with osteoarthrosis (OA); the mean follow-up period was 33 months. At clinical investigation after 1 year, no signs of pain or swelling were found in 15 knees. In most cases, pain and swelling improved subjectively, with a mean duration of 11 months; in 20 knees, the improvement lasted more than 22 months. When radiographs showed severse destruction, 90 Y treatment was unsuccessful, but an important new finding was that most patients with mild or moderate radiological abormalities appeared to have a long-lasting improvement. The result did not correlate with erythrocyte sedimentation rate (ESR), haemoglobin or Rose titre at the time of injection or at follow up, suggesting that the result of the treatment is more dependent on local factors than on the disease activity. The results of 90 Y treatment in 6 OA knees with persistent swelling were promising regarding swelling, even in patients with moderate radiological abnormalities. The main side-effect was a sometimes painful swelling of the knee, which was always successfully treated with an intra-articular corticosteroid injection. In 90 Y-treated knees, the incidence of unstable joints was not significantly higher than in non-treated knees. In conclusion, 90 Y synovectomy may be a succesful treatment for patients older than 50 years with chronic arthritis of the knee due to RA and probably also OA, even when moderate radiological abnormalities are present.

    Objective. Studies on the effect of subthalamic deep brain stimulation (STN-DBS) on executive functioning in Parkinson's disease (PD) are still controversial. In this study we compared self-reported daily executive functioning in PD patients before and after three months of STN-DBS. We also examined whether executive functioning in everyday life was associated with motor symptoms, apathy, and psychiatric symptoms. Method. 40 PD patients were examined with the Behavior Rating Inventory of Executive Function-Adult Version (BRIEF-A), the Symptom Checklist 90-Revised (SCL-90-R), and the Apathy Evaluation Scale (AES-S). Results. PD patients reported significant improvement in daily life executive functioning after 3 months of STN-DBS. Anxiety scores significantly declined, while other psychiatric symptoms remained unchanged. The improvement of self-reported executive functioning did not correlate with motor improvement after STN-DBS. Apathy scores remained unchanged after surgery. Only preoperative depressed mood had predictive value to the improvement of executive function and appears to prevent potentially favorable outcomes from STN-DBS on some aspects of executive function. Conclusion. PD patients being screened for STN-DBS surgery should be evaluated with regard to self-reported executive functioning. Depressive symptoms in presurgical PD patients should be treated. Complementary information about daily life executive functioning in PD patients might enhance further treatment planning of STN-DBS.

    The aim of this survey was to evaluate the distribution of pathological gamblers treated in an alcohol or drug addiction treatment program run by the Italian National Health Service providing assistance to alcohol and drug abusers in Venice (North east Italy) from September 1 to December 31, 2001. Each drug- or alcohol-dependent patient retained for treatment for at least one month was administrated an anonymous precoded questionnaire to collect personal and socio-demographic features. The South Oaks Gambling Screen (SOGS) was used to measure pathological gambling and the Symptom Checklist-90-Revised (SCL-90-R) to measure psychological distress levels and psychiatric symptoms. Among the 113 enrolled subjects we found a greater prevalence of pathological gamblers among drug users than among alcoholics and drug abusers were younger than alcoholics; moreover, there was a prevalence of single status, low schooling, and a low-medium income despite full-time occupation. Only pathological gamblers revealed a significant positive correlation with a family history of gambling and reached positive scores (>1.5) for some likely psychiatric symptoms. Abuse disorders and pathological gambling are frequently associated with multidependence personality traits. Preventing substance abuse may reduce the pathological gambling rates and better results can be obtained with educational campaigns beginning earlier in life.

    Often, in the stage of research and development of new techniques for detection of ionizing radiation, elaborate electronic systems are required. In this paper, we describe the relatively complex detector and electronic system used for a relatively simple but nevertheless demanding measurement of the beta emitting radionuclides 90 Sr/ 90 Y in environmental samples. The detection limit of 1 Bq in a thin, disc-shaped sample, was obtained by careful elimination of background. Contribution of other radionuclides in the sample, were eliminated or at least considerably reduced by using a silica aerogel as Cherenkov radiator and thin multiwire chamber in coincidence. Cosmic ray signals were reduced by large scintillation counters in anticoincidence. Finally, persisting RF pick-up signals were eliminated by using the signal from a wire antenna and identical MWPC preamplifier and discriminator for a veto to the master coincidence. For each accepted event, both timing and pulse height information was recorded with a personal computer

    The extrapolation chamber is a parallel plate chamber and variable volume based on the Bragg-Gray theory. It determines in absolute mode, with high accuracy the dose absorbed by the extrapolation of the ionization current measured for a null distance between the electrodes. This camera is used for dosimetry of external beta rays for radiation protection. This paper presents the characterization of an extrapolation chamber in a 90 Sr/ 90 Y beta radiation field. The absorbed dose rate to tissue at a depth of 0.07 mm was calculated and is (0.13206±0.0028) μGy. The extrapolation chamber null depth was determined and its value is 60 μm. The influence of temperature, pressure and humidity on the value of the corrected current was also evaluated. Temperature is the parameter that has more influence on this value and the influence of pressure and the humidity is not very significant. Extrapolation curves were obtained. (Author)

    Patients with chronic autoimmune atrophic gastritis (CAAG) often refer digestive symptoms and are prescribed antisecretory medications. Aims were to investigate: (i) gastro-esophageal reflux (GER), (ii) psychopathological profile, (iii) frequency of use and clinical benefit of antisecretory drugs. Prospective observational study on 41 CAAG patients who underwent: 24 h multichannel intra-luminal impedance-pH (MII-pH) monitoring off-therapy, standardized medical interview and psychological questionnaire (i.e., SCL-90R). The medical interview was repeated at least 1 month after MII-pH in patients who were using antisecretory drugs. Statistical analysis was performed calculating median (10th-90th percentiles) and risk ratios (RR) with 95% confidence interval. Median intra-gastric pH was 6.2 (4.6-7.0). One patient had acid reflux (AC) associated with symptoms, five had increased total reflux number and four had symptoms associated to non-acid reflux (NA) (patients referred as 'GER positive'). Using patients 'GER negative' with normal SCL-90R as reference, the RR of being symptomatic in patients GER positive was 2.1 (1.1-4.1) if SCL-90R was normal and 0.9 (0.5-1.7) if it was altered (difference in RR significant being p = 0.04). Seventeen/28 (61%) symptomatic patients were on antisecretory drugs, which were stopped in 16 of them according to results of MII-pH and clinical evaluation after 574 days (48-796) showed that symptoms were unchanged. In patients with CAAG (i) AC reflux rarely occurred whereas increased NA reflux was not infrequent both being related to symptoms in some patients, (ii) psychopathological profile has a role in symptoms' occurrence, (iii) antisecretory drugs were generally inappropriately used and clinically ineffective. © 2015 John Wiley & Sons Ltd.

    Polygamy is defined as a marriage in which a spouse of either gender has more than one mate at the same time. Polygamy is considered a valid form of marriage in many countries and communities around the globe. The purpose of this study is to examine the psychological symptoms, family function, marital satisfaction, life satisfaction and the degree of agreement with the practice of polygamy among 'senior wives' - the first wife in the polygamous marriage - and women in monogamous marriages in the West Bank, Palestine. A convenience sample of 309 women, 187 from polygamous and 122 from monogamous families, participated in this study. All women from polygamous families were senior wives. The following instruments were deployed: the McMaster Family Assessment Device (FAD), the ENRICH marital satisfaction questionnaire, the SCL-90 mental health symptoms checklist, the Rosenberg self-esteem (SE) scale, the Diener et al. (1985), a life satisfaction scale, and a basic socio-demographic scale, including the degree of agreement of the practice of polygamy. The findings revealed significant differences between senior wives in polygamous marriages and wives in monogamous marriages with regard to family functioning, marital satisfaction, self-esteem and life satisfaction. Likewise, many of the mental health symptoms were different. Particularly noteworthy were somatization, depression, hostility psychotism and the General Severity Index (a global index of distress). More women in polygamous marriages agreed with the practice of polygamy than their monogamous counterparts. Practitioners and policy makers need to be aware of the consequences of polygamy on first wives and on society as whole.

    Full text: Aim: Cell membrane-specific somatostatin receptors are usually expressed by neuroendocrine tumors. Radiolabelled receptor-binding somatostatin analogues target tissues expressing these receptors and can be used for visualization and treatment. After the localization of tumors bearing somatostatin receptors with 111In or 99mTc labeled somatostatin analogues, in the case of high tumor uptake related to non target tissues, different radioisotopes have been used for their treatment. Thus, application of high doses of 111In- DTPA-octreotide had an impact on improvement of the clinical symptoms, without significant reduction of the tumor mass. However, 90Y somatostatin analogues (DOTA TOC, lanreotide) may be more effective for reduction of the tissue of the larger tumors while 177Lu labeled ones may be applied in smaller tumors. Combination of both of them seems to be the most effective therapy, particularly in tumors bearing both small and large lesions. The aim of this work is presentation of the preliminary results of the therapy of NETs with another octreotide analogue, 90Y DOTA TATE, which so far has been proved to have high therapeutic potential when labeled with 177Lu. Patients and methods: We investigated 7 patients with neuroendocrine tumors (two patients had neuroendocrine pancreatic carcinomas with liver metastases (one of them had metastases in peritoneal lymph nodes), one patient with operated (resected) bronchial carcinoid and liver metastases, three patients with neuroendocrine carcinomas of unknown origin and hepatic metastases (one with skeletal metastases) and one with pancreatic gastrinoma without metastases (surgery was impossible to perform). In all of them, together with other laboratory analyses and imaging methods, scintigraphy with somatostatin analogues was performed (in 3 with 111In Octreoscan and in the other 4 with 99mTc HYNIC TOC) and high tumor uptake was observed. The therapy was performed with 2- 4,5 GBq 90Y DOTA TATE per

    2005-02-01

    Full Text Available Groundwater contamination from 90Sr is an environmental challenge posed topresent and former nuclear weapons related sites. Traditional methods of extractinggroundwater samples and performing laboratory analyses are expensive, time-consumingand induce significant disposal challenges. The authors present here a prototype countercapable of measuring 90Sr groundwater concentrations in-situ at or below the drinking waterlimit of 8 pCi/liter. The 90Y daughter of 90Sr produces high-energy electrons, which cancreate Cerenkov light. Photomultiplier tubes convert the Cerenkov light into an electronicpulse, which then undergoes signal processing with standard electronics. Strontium-90concentrations near the drinking water limit can be measured in a matter of hours if it is insecular equilibrium with the 90Y daughter. The prototype counter is compact, can bedeployed in an American Standard 6-inch, well while operated by a single person, andtransmits the results to a central monitoring location.

    The change of strontium-90 content in water and silts of the Dnieper cascade water reservoirs was analyzed. It was shown, that decrease of strontium-90 content in water in time connected basically with ion exchange adsorption of strontium-90 by residues. A high sorption ability of residues made it possible for radioisotopes to reduce sharply their concentration along depth of soils. The highest concentration of radioisotopes was in the upper layers, enriched by silt. It was ascertained, that strontium-90 migration along depth of residues took place rapidly in the Kiev's water reservoir. Down the cascade strontium-90 content reduced in lower layers of residues as well as in upper layers. 4 tabs

    Molecular chaperones are reported to be crucial for virus propagation, but are not yet addressed in Human Enterovirus 71 (EV71). Here we describe the specific association of heat shock protein-90-beta (Hsp90β), but not alpha form (Hsp90α), with EV71 viral particles by the co-purification with virions using sucrose density gradient ultracentrifugation, and by the colocalization with viral particles, as assessed by immunogold electron microscopy. The reduction of the Hsp90β protein using RNA interference decreased the correct assembly of viral particles, without affecting EV71 replication levels. Tracking ectopically expressed Hsp90β protein associated with EV71 virions revealed that Hsp90β protein was transmitted to new host cells through its direct association with infectious viral particles. Our findings suggest a new antiviral strategy in which extracellular Hsp90β protein is targeted to decrease the infectivity of EV71 and other enteroviruses, without affecting the broader functions of this constitutively expressed molecular chaperone. - Highlights: • Hsp90β is associated with EV71 virion and is secreted with the release virus. • Hsp90β effects on the correct assembly of viral particles. • Viral titer of cultured medium was reduced in the presence of geldanamycin. • Viral titer was also reduced when Hsp90β was suppressed by siRNA treatment. • The extracellular Hsp90β was also observed in other RNA viruses-infected cells

    Several studies have been published in the literature on the extent and levels of radioactive contamination of food chains caused by fallout from nuclear weapon tests. According to UNSCEAR, these studies cover a great number of:-areas of the developed world, though large, areas of Asia, Africa and South-America are left aside with only, unsatisfactory information about the levels, of radioactive contamination. In 1968, UNSCEAR recommended that a survey on the contamination of biological materials such as human - bone by fission products and particularly Sr 90 should be encouraged on those areas where only fragmentary information was available. UNSCEAR recommendations call upon the fact that many individuals on such areas of the world have been exposed to Sr 90 contamination from birth to their adult area. Therefore, that group have an Sr 90 skeletal burden very much different from people exposed only at adult age. Based on these considerations, UNSCEAR recommendations called for Sr 90 analysis on human bones from different age groups. In Brazil, studies on the of Sr 90 in human bone are practically non-existent, except for the year of 1959. Following UNSCEAR recommendations, we decided to perform such a survey on Sr 90 levels in human bones. Samples were collected from individuals that died in Rio de Janeiro from accidents. These samples were firstly classified according to social level in very poor and poor groups. Samples were then classified in three age groups ranging 0-18, 18-30 and 30-40 years of age. Results show that levels found in the Brazilian age groups are close to the ones observed in Chile (1969), Argentina and Australia (1966-1968) and slightly, higher than -those observed in Venezuela, Senegal and Jamaica (1969). If one compares the results obtained for the North and South hemispheres respectively, one sees that there was a more pronounced decrease in the levels of Sr 90 content of the of some regions of South America. Our results show no

    We illustrate how Fortran 90 supports object-oriented concepts by example of plasma particle computations on the IBM SP. Our experience shows that Fortran 90 and object-oriented methodology give high performance while providing a bridge from Fortran 77 legacy codes to modern programming principles. All of our object-oriented Fortran 90 codes execute more quickly thatn the equeivalent C++ versions, yet the abstraction modelling capabilities used for scentific programming are comparably powereful.

    The protein-folding chaperone Hsp90 has been proposed to buffer the phenotypic effects of mutations. The potential for Hsp90 and other putative buffers to increase robustness to mutation has had major impact on disease models, quantitative genetics, and evolutionary theory. But Hsp90 sometimes contradicts expectations for a buffer by potentiating rapid phenotypic changes that would otherwise not occur. Here, we quantify Hsp90's ability to buffer or potentiate (i.e., diminish or enhance) the effects of genetic variation on single-cell morphological features in budding yeast. We corroborate reports that Hsp90 tends to buffer the effects of standing genetic variation in natural populations. However, we demonstrate that Hsp90 tends to have the opposite effect on genetic variation that has experienced reduced selection pressure. Specifically, Hsp90 tends to enhance, rather than diminish, the effects of spontaneous mutations and recombinations. This result implies that Hsp90 does not make phenotypes more robust to the effects of genetic perturbation. Instead, natural selection preferentially allows buffered alleles to persist and thereby creates the false impression that Hsp90 confers greater robustness.

    Radiopeptide therapy is commonly performed with a single radioisotope. We aimed to compare the effectiveness of somatostatin-based radiopeptide therapy with a single versus a combination of radioisotopes. In a cohort study, patients with metastasized neuroendocrine cancer were treated with repeated cycles of (90)yttrium-labeled tetraazacyclododecane-tetraacetic acid modified Tyr-octreotide ([(90)Y-DOTA]-TOC) or with cycles alternating between [(90)Y-DOTA]-TOC and (177)lutetium-labeled DOTA-TOC ([(177)Lu-DOTA]-TOC) until tumor progression or permanent toxicity. Multivariable Cox regression and competing risk regression were used to study predictors of survival and renal toxicity in patients completing three or more treatment cycles. A total of 486 patients completed three or more treatment cycles; 237 patients received [(90)Y-DOTA]-TOC and 249 patients received [(90)Y-DOTA]-TOC + [(177)Lu-DOTA]-TOC. Patients receiving [(90)Y-DOTA]-TOC + [(177)Lu-DOTA]-TOC had a significantly longer survival than patients receiving [(90)Y-DOTA]-TOC alone (5.51 v 3.96 years; hazard ratio, 0.64; 95% CI, 0.47 to 0.88; P = .006). The rates of severe hematologic toxicities (6.3% v 4.4%; P = .25) and severe renal toxicity (8.9% v 11.2%; P = .47) were comparable in both groups. [(90)Y-DOTA]-TOC + [(177)Lu-DOTA]-TOC was associated with improved overall survival compared with [(90)Y-DOTA]-TOC alone in patients completing three or more cycles of treatment. Contrary to the current practice in radiopeptide therapy, our results suggest an advantage of using a combination of radioisotopes.

    Background & objectives: Radioimmunotherapy is extensively being used for the treatment of non-Hodgkin's lymphoma (NHL). Use of rituximab, a chimeric anti-CD20 antibody directed against the CD20 antigen in combination with suitable beta emitters is expected to result in good treatment response by its cross-fire and bystander effects. The present work involves the conjugation of p-isothiocyanatobenzyl DOTA (p-SCN-Bn-DOTA) to rituximab, its radiolabelling with 90Y and in vitro and in vivo evaluation to determine its potential as a radioimmunotherapeutic agent. Methods: Rituximab was conjugated with p-SCN-Bn-DOTA at 1:1 antibody: DOTA molar ratio. The number of DOTA molecules linked to one molecule of rituximab was determined by radioassay and spectroscopic assay. Radiolabelling of rituximab with 90Y was carried out and its in vitro stability was evaluated. In vitro cell binding studies were carried out in Raji cells expressing CD20 antigen. Biodistribution studies were carried out in normal Swiss mice. Results: Using both radioassay and spectroscopic method, it was determined that about five molecules of DOTA were linked to rituximab. Radiolabelling of the rituximab conjugate with 90Y and subsequent purification on PD-10 column gave a product with radiochemical purity (RCP) > 98 per cent which was retained at > 90 per cent up to 72 h when stored at 37°C. In vitro cell binding experiments of 90Y-DOTA-rituximab with Raji cells exhibited specific binding of 20.7 ± 0.1 per cent with 90Y-DOTA-rituximab which reduced to 15.5 ± 0.2 per cent when incubated with cold rituximab. The equilibrium constant Kd for 90Y-DOTA-Rituximab was determined to be 3.38 nM. Radiolabelled antibody showed clearance via hepatobiliary and renal routes and activity in tibia was found to be quite low indicating in vivo stability of 90Y-DOTA-rituximab. Interpretation & conclusions: p-SCN-Bn-DOTA was conjugated with rituximab and radiolabelling with 90Y was carried out. In vitro studies carried

    Full Text Available Severe pre-eclampsia is the second highest cause of maternal mortality. Free radicals that stimulate heat shock protein 90 (HSP 90 are believed to determine severe pre-eclampsia. HSP90 is an important protein that helps the establishment and maintenance of other proteins. It also increases the life time of cells after various pathological conditions (chaperone function. The chaperone function is the adaptation key factor to endogenous stress in tissues. By recognizing HSP90 level in early detection of severe pre-eclampsia, prevention and management can be started early. This study aimed to prove that the HSP90 level in pregnancy with severe pre-eclampsia is higher than normal pregnancy. This was a quantitative study using cross sectional approach by testing the HSP90 level. The study was conducted during the period of September to November 2013, at the Obstetrics and Gynecological Unit, Moewardi Hospital Surakarta and Prodia Laboratory Jakarta. The number of subjects was 30 patients, consisting of 15 normal pregnant mothers and 15 pregnant mothers with pre-eclampsia . The calculation of serum HSP90 level was conducted using enzyme-linked immunosorbent assay (ELISA. Data were analyzed using t-test using SPSS for Windows version 17 for Windows. The mean of HSP90 in the severe pre-eclampsia group was 131.91±26.66 while the mean in the normal pregnancy group was 80.28±13.39 with p=0.00 (p<0.05. Level of HSP90 serum in severe pre-eclampsia is higher than in normal pregnancy, due to the occurrence of oxidative stress in severe pre-eclampsia

    Elevated Hsp90 expression has been documented in breast ductal carcinomas, whereas decreased Hsp90 expression has been reported in precursor lobular lesions. This study aims to assess Hsp90 expression in infiltrative lobular carcinomas of the breast. Tissue specimens were taken from 32 patients with infiltrative lobular carcinoma. Immunohistochemical assessment of Hsp90 was performed both in the lesion and the adjacent normal breast ducts and lobules; the latter serving as control. Concerning Hsp90 assessment: i) the percentage of positive cells and ii) the intensity were separately analyzed. Subsequently, the Allred score was adopted and calculated. The intensity was treated as an ordinal variable-score (0: negative, low: 1, moderate: 2, high: 3). Statistical analysis followed. All infiltrative lobular carcinoma foci mainly presented with a positive cytoplasmic immunoreaction for Hsp90. Compared to the adjacent normal ducts and lobules, infiltrative lobular carcinoma exhibited a statistically significant decrease in Hsp90 expression, both in terms of Hsp90 positive cells (%) and Allred score (74.2 ± 11.2 vs. 59.1 ± 14.2 p = 0.0001; 7.00 ± 0.95 vs. 6.22 ± 1.01, p = 0.007, Wilcoxon matched-pairs signed-ranks test). Concerning the intensity of Hsp90 immunostaining only a marginal decrease was noted (2.16 ± 0.68 vs. 1.84 ± 0.63, p = 0.087, Wilcoxon matched-pairs signed-ranks test). ILC lesions seem to exhibit decreased Hsp90 expression, a finding contrary to what might have been expected, given that high Hsp90 expression is a trait of invasive ductal carcinomas

    We investigated the role of Heat shock protein 90 (Hsp90) in vitamin D action in Caco-2 cells using geldanamycin (GA) to block Hsp90 function and RNA interference to reduce Hsp90β expression. When cells were exposed to GA, vitamin D-mediated gene expression and transcriptional activity were inhibited by 69% and 54%, respectively. Gel shift analysis indicated that GA reduced vitamin D-mediated DNA binding activity of the vitamin D receptor (VDR). We tested the specific role of Hsp90β by knocking down its expression with stably expressed short hairpin RNA. Vitamin D-induced gene expression and transcriptional activity were reduced by 90% and 80%, respectively, in Hsp90β-deficient cells. Nuclear protein for VDR and RXRα, its heterodimer partner, were not reduced in Hsp90β-deficient cells. These findings indicate that Hsp90β is needed for optimal vitamin D responsiveness in the enterocyte and demonstrate a specific role for Hsp90β in VDR signaling

    The paper presents results on determination of 90 Sr in bilberry and cowberry leaves (Vaccinium myrtillus and Vaccinium vitis-idaea) and the use of these plants as bio-monitors of radiostrontium contamination in Poland. Radiostrontium was determined by mean of liquid scintillation spectrometry preceded by radiochemical separation using Sr-resin and 85 Sr tracer. The approximate map of 90 Sr contamination of Poland is presented. The activity ratio between 90 Sr and obtained earlier data for 137 Cs in the same samples is discussed. The enhancement of radiostrontium content observed in northeastern Poland seems to be the trace of hot-particles fallout from initial Chernobyl cloud, which passed over Polish territory toward Scandinavia.

    Yttrium-90 is known to have a low positron emission decay of 32 ppm that may allow for personalized dosimetry of liver cancer therapy with (90)Y labeled microspheres. The aim of this work was to image and quantify (90)Y so that accurate predictions of the absorbed dose can be made. The measurements were performed within the QUEST study (University of Sydney, and Sirtex Medical, Australia). A NEMA IEC body phantom containing 6 fillable spheres (10-37 mm ∅) was used to measure the 90Y distribut...

  10. Deposition of 90Sr in bone and the relevant dose

    The deposition of fallout 90 Sr in bone and radiation dose from the nuclide in Japan is reviewed with special reference to (i) the intraskeletal distribution of 90 Sr and reference bone, (ii) bone models for predicting 90 Sr level and (iii) possible problems in applying dose rate factors to Japanese, especially to infants and adolescents. An evidence is presented for the assumption that the ratio of the 90 Sr concentration in a particular bone to that in vertebra will reach the ratio observed for stable strontium under the virtually constant intake of 90 Sr. The importance of surveying 90 Sr levels in different bones is stressed. Observed Ratios (bone/diet) found for Japanese are noticeably lower than those reported for Europeans and Americans. The recently presented model for the retention of alkaline earth elements in man by ICRP will be useful if only adults are concerned. Dose rate factors for 90 Sr in bone should be given as a function of age for the purpose of better estimation of dose commitments. The cumulative absorbed doses to bone tissues calculated with the Palmley-Mays model and with the Spiers model show remarkably higher levels in school children and young adults than the mean level.

    2000-01-01

    Strontium-90, a radioactive contaminant from historical operations at the U.S. Department of Energy (DOE) Hanford Site, enters the Columbia River at several locations associated with former plutonium production reactors at the Site. Strontium-90 is of concern to humans and the environment because of its moderately long half-life (29.1 years), its potential for concentrating in bone tissue, and its relatively high energy of beta decay. Although strontium-90 in the environment is not a new issue for the Hanford Site, recent studies of near-river vegetation along the shoreline near the 100 Areas raised public concern about the possibility of strontium-90-contaminated groundwater reaching the riverbed and fall chinook salmon redds. To address these concerns, DOE asked Pacific Northwest National Laboratory (PNNL) to prepare this report on strontium-90, its distribution in groundwater, how and where it enters the river, and its potential ecological impacts, particularly with respect to fall chinook salmon. The purpose of the report is to characterize groundwater contaminants in the near-shore environment and to assess the potential for ecological impact using salmon embryos, one of the most sensitive ecological indicators for aquatic organisms. Section 2.0 of the report provides background information on strontium-90 at the Hanford Site related to historical operations. Public access to information on strontium-90 also is described. Section 3.0 focuses on key issues associated with strontium-90 contamination in groundwater that discharges in the Hanford Reach. The occurrence and distribution of fall chinook salmon redds in the Hanford Reach and characteristics of salmon spawning are described in Section 4.0. Section 5.0 describes the regulatory standards and criteria used to set action levels for strontium-90. Recommendations for initiating additional monitoring and remedial action associated with strontium-90 contamination at the Hanford Site are presented in Section 6

  14. Radioembolization and the dynamic role of 90Y PET/CT

    Full Text Available Before the advent of tomographic imaging, it was postulated that decay of 90Y to the 0+ excited state of 90Zr may result in emission of a positron-electron pair. While the branching ratio for pair production is small (~32x10-6, PET has been successfully used to image 90Y in numerous recent patient and phantom studies. 90Y PET imaging has been performed on a variety of PET/CT systems, with and without time-of-flight (TOF and/or resolution recovery capabilities as well as on both BGO and L(YSO based scanners. On all systems, resolution and contrast superior to bremsstrahlung SPECT has been reported. The intrinsic radioactivity present in L(YSO-based PET scanners is a potential limitation associated with accurate quantification of 90Y. However, intrinsic radioactivity has been shown to have a negligible effect at the high activity concentrations common in 90Y radioembolization. Accurate quantification is possible on a variety of PET scanner models, with or without TOF, although TOF improves accuracy at lower activity concentrations. Quantitative 90Y PET images can be transformed into 3D maps of absorbed dose based on the premise that the 90Y activity distribution does not change after infusion. This transformation has been accomplished primarily with the use of 3D dose point-kernel convolution. From a clinical standpoint, 90Y PET provides a superior post-infusion evaluation of treatment technical success owing to its improved resolution. Absorbed dose maps generated from quantitative PET data can be used to predict treatment efficacy and manage patient follow-up. For patients who receive multiple treatments, this information can also be used to provide patient-specific treatment planning for successive therapies, potentially improving response. The broad utilization of 90Y PET has the potential to provide a wealth of dose-response information, which may lead to development of improved radioembolization treatment-planning models in the future.

  15. Effects of lifetime ingestion of 90Sr in beagle dogs

    To investigate the effects of lifetime 90 Sr ingestion, fifteen beagle dogs were fed the equivalent of 1.3, 4.0, and 12.0 μCi 90 Sr. Exposures prior to weaning were made by maternal administration of one of the same 90 Sr levels, begining at 21 days of gestation. Median survival was 12.5 years for the 1.3 μCi/day group, 6.5 years for the 4 μCi/day group, and 5.2 years of the 12 μCi/day group, compared to unirradiated control values of 14.5 to 15 years. The normal life span of more than half of the 1.3 μCi/day group is remarkable, considering they ingested 5900 to 7500 μCi 90 Sr during their lifetimes. One of seven 1.3 μCi/day dogs died of mycloproliferative syndrome (MPS), while one of four 4 μCi/day and one of four 12 μCi/day dogs died from MPS. In addition, another 12 μCi/day dog died of osteosarcoma and two others in the same group showed skeletal changes related to 90 Sr exposure. Other deaths were as could be expected in normal canine populations. Lifetime skeletal doses, determined by periodic whole-body counting, were 1990-3750, 1880-9230, and 6360-14,680 rad for the 1.3, 4, and 12 μCi/day groups, respectively. Comparison of these values with those from the large 90 Sr toxicity study at Davis in which 90 Sr feeding ended at 18 months of age indicates similar average skeletal doses from the two types of feeding regimens. The similarity of the skeletal doses may relate to the inability of 90 Sr to be incorporated to any great extent into a mature skeleton that no longer has the high calcium turnover associated with early life. As a result, deaths from lifetime 90 Sr ingestion appeared no earlier than when 90 Sr ingestion ended in early adulthood

    This report focuses on enhancements to prototype building models used to determine the energy impact of various versions of ANSI/ASHRAE/IES Standard 90.1. Since the last publication of the prototype building models, PNNL has made numerous enhancements to the original prototype models compliant with the 2004, 2007, and 2010 editions of Standard 90.1. Those enhancements are described here and were made for several reasons: (1) to change or improve prototype design assumptions; (2) to improve the simulation accuracy; (3) to improve the simulation infrastructure; and (4) to add additional detail to the models needed to capture certain energy impacts from Standard 90.1 improvements. These enhancements impact simulated prototype energy use, and consequently impact the savings estimated from edition to edition of Standard 90.1.
