    In rodents, insufficient thyroid hormone (TH) gestationally has adverse effects on cerebral cortex development. Comparable studies of humans examining how TH insufficiency affects cortical morphology are limited to children with congenital hypothyroidism or offspring of hypothyroxinemic women; effects on cortex of children born to women with clinically diagnosed hypothyroidism are not known. We studied archived MRI scans from 22 children aged 10–12 years born to women treated for preexisting or de novo hypothyroidism in pregnancy (HYPO) and 24 similar age and sex controls from euthyroid women. FreeSurfer Image Analysis Suite software was used to measure cortical thickness (CT) and a vertex-based approach served to compare HYPO versus control groups and Severe versus Mild HYPO subgroups as well as to perform regression analyses examining effects of trimester-specific maternal TSH on CT. Results showed that relative to controls, HYPO had multiple regions of both cortical thinning and thickening, which differed for left and right hemispheres. In HYPO, thinning was confined to medial and mid-lateral regions of each hemisphere and thickening to superior regions (primarily frontal) of the left hemisphere and inferior regions (particularly occipital and temporal) of the right. The Severe HYPO subgroup showed more thinning than Mild in frontal and temporal regions and more thickening in bilateral posterior and frontal regions. Maternal TSH values predicted degree of thinning and thickening within multiple brain regions, with the pattern and direction of correlations differing by trimester. Notably, some correlations remained when cases born to women with severe hypothyroidism were removed from the analyses, suggesting that mild variations of maternal TH may permanently affect offspring cortex. We conclude that maternal hypothyroidism during pregnancy has long-lasting manifestations on the cortical morphology of their offspring with specific effects reflecting both

    After establishing the diagnosis of an insulinoma, most surgeons prefer preoperative localization. Selective arteriography is usually considered the gold standard for this purpose. Recently, computed tomography (CT) and preoperative US have contended the role to angiography. MRI has been used in few cases of endocrine pancreatic tumors, and its role in this particular field has to be defined. Between November 1988-September 1990 7 adult patients who had undergone surgery were evaluated. Eight tumors were resected in 6 patients who were cured; in an 18-year-old woman surgical treatment was unsuccessful. Arterio-graphy, CT, preoperative US, MRI and intraoperative US detected 2, 6, 6, 5 and 6 tumors respectively. Two insulinomas (0.2 and 0.7 cm) were found at histologic examination in resected specimen. The ability of intra-operative US and careful surgical exploration to resolve more than 90 percent of cases makes the preoperative use of arteriography and CT questionable value. If further experience confirms these findings, US and MRI may suffice. (author). 13 refs.; 3 figs.; 1 tab.

    As wind turbines increase in size and the demands for lifetime also increases, new methods of load reduction needs to be examined. One method is to make the yaw system of the turbine soft/flexible and hence dampen the loads to the system. This paper presents work previous done on this subject...... with foucus on hydraulic yaw systems. By utilizing the HAWC2 aeroelastic code and an extended model of the NREL 5MW turbine studies shows that a significant reduction in fatigue loads to the yaw system and rotor shaft is possible by the soft yaw drive concept....

    Core cognitive schemas may play a role in the vulnerability for sexual offending. Identifying these schemas could help to conceptualize sexual crimes and rehabilitate convicted sexual offenders. The aim of this preliminary study was to explore the relationship between early maladaptive schemas (EMSs) and sexual offending, as well as how rapists and child sex molesters differ in terms of these schemas. Thirty-two men convicted for rape, 33 convicted for child sexual abuse, and 30 non-offenders were evaluated using the Young Schema Questionnaire (YSQ-S3) and the Brief Symptom Inventory (BSI). Results showed that participants convicted for child sexual abuse presented significantly more schemas from the disconnection/rejection, impaired autonomy/performance, other directness, and over vigilance/inhibition domains than non-offenders, whereas rapists presented more schemas from the impaired autonomy/performance domain than non-offenders. Differences between sex offenders showed that child molesters presented more schemas of pessimism than rapists. Preliminary findings suggested that EMSs may impact sex offender's perceptions about themselves and about the world. Schema-focused therapy (Young, 1990, 1999) may thus be an acceptable approach to sex offender's psychological assessment and intervention.

    Objective: We aimed to detect the frequency of restricted diffusion in intracerebral metastases and to find whether there is correlation between the primary tumor pathology and diffusion-weighted MR imaging (DWI) findings of these metastases. Material and methods: 87 patients with intracerebral metastases were examined with routine MR imaging and DWI. 11 hemorrhagic metastatic lesions were excluded. The routine MR imaging included three plans before and after contrast enhancement. The DWI was performed with spin-echo EPI sequence with three b values (0, 500 and 1000), and ADC maps were calculated. 76 patients with metastases were grouped according to primary tumor histology and the ratios of restricted diffusion were calculated according to these groups. ADCmin values were measured within the solid components of the tumors and the ratio of metastases with restricted diffusion to that which do not show restricted diffusion were calculated. Fisher's exact and Mann-Whitney U tests were used for the statistical analysis. Results: Restricted diffusion was observed in a total of 15 metastatic lesions (19, 7%). Primary malignancy was lung carcinoma in 10 of these cases (66, 6%) (5 small cell carcinoma, 5 non-small cell carcinoma), and breast carcinoma in three cases (20%). Colon carcinoma and testicular teratocarcinoma were the other two primary tumors in which restricted diffusion in metastasis was detected. There was no statistical significant difference between the primary pathology groups which showed restricted diffusion (p > 0.05). ADCmin values of solid components of the metastasis with restricted diffusion and other metastasis without restricted diffusion also showed no significant statistical difference (0.72 {+-} 0.16 x 10{sup -3} mm{sup 2}/s and 0.78 {+-} 21 x 10{sup -3} mm{sup 2}/s respectively) (p = 0.325). Conclusion: Detection of restricted diffusion on DWI in intracerebral metastasis is not rare, particularly if the primary tumor is lung or breast

    We review the literature on the relation between narcissism and consumer behavior. Consumer behavior is sometimes guided by self-related motives (e.g., self-enhancement) rather than by rational economic considerations. Narcissism is a case in point. This personality trait reflects a self-centered, self-aggrandizing, dominant, and manipulative orientation. Narcissists are characterized by exhibitionism and vanity, and they see themselves as superior and entitled. To validate their grandiose self-image, narcissists purchase high-prestige products (i.e., luxurious, exclusive, flashy), show greater interest in the symbolic than utilitarian value of products, and distinguish themselves positively from others via their materialistic possessions. Our review lays the foundation for a novel methodological approach in which we explore how narcissism influences eye movement behavior during consumer decision-making. We conclude with a description of our experimental paradigm and report preliminary results. Our findings will provide insight into the mechanisms underlying narcissists' conspicuous purchases. They will also likely have implications for theories of personality, consumer behavior, marketing, advertising, and visual cognition.

    Background This article reports three studies describing the development and validation of the 12-item Sensitivity to Pain Traumatization Scale (SPTS-12). SPT refers to the anxiety-related cognitive, emotional, and behavioral reactions to pain that resemble the features of a traumatic stress reaction. Methods In Study 1, a preliminary set of 79 items was administered to 116 participants. The data were analyzed by using combined nonparametric and parametric item response theory resulting in a 12-item scale with a one-factor structure and good preliminary psychometric properties. Studies 2 and 3 assessed the factor structure and psychometric properties of the SPTS-12 in a community sample of 823 participants (268 with chronic pain and 555 pain-free) and a clinical sample of 345 patients (126 with chronic post-surgical pain, 92 with other nonsurgical chronic pain, and 127 with no chronic pain) at least 6 months after undergoing coronary artery bypass graft surgery, respectively. Results The final SPTS-12 derived from Study 1 comprised 12 items that discriminated between individuals with different levels of SPT, with the overall scale showing good to very good reliability and validity. The results from Studies 2 and 3 revealed a one-factor structure for chronic pain and pain-free samples, excellent reliability and concurrent validity, and moderate convergent and discriminant validity. Conclusion The results of the three studies provide preliminary evidence for the validity and reliability of the SPTS-12. PMID:28615962

    The role of the endocannabinoid system in nicotine addiction is being increasingly acknowledged. We conducted a pilot, randomised double blind placebo controlled study set out to assess the impact of the ad-hoc use of cannabidiol (CBD) in smokers who wished to stop smoking. 24 smokers were randomised to receive an inhaler of CBD (n=12) or placebo (n=12) for one week, they were instructed to use the inhaler when they felt the urge to smoke. Over the treatment week, placebo treated smokers showed no differences in number of cigarettes smoked. In contrast, those treated with CBD significantly reduced the number of cigarettes smoked by ~40% during treatment. Results also indicated some maintenance of this effect at follow-up. These preliminary data, combined with the strong preclinical rationale for use of this compound, suggest CBD to be a potential treatment for nicotine addiction that warrants further exploration.

    The literature on Multiple Perpetrator Rape (MPR) is scant; however, a significant proportion of sexual offending involves multiple perpetrators. In addition to the need for research with apprehended offenders of MPR, there is also a need to conduct research with members of the general public. Recent advances in the forensic literature have led to the development of self-report proclivity scales. These scales have enabled researchers to conduct evaluative studies sampling from members of the general public who may be perpetrators of sexual offenses and have remained undetected, or at highest risk of engaging in sexual offending. The current study describes the development and preliminary validation of the Multiple-Perpetrator Rape Interest Scale (M-PRIS), a vignette-based measure assessing community males' sexual arousal to MPR, behavioral propensity toward MPR and enjoyment of MPR. The findings show that the M-PRIS is a reliable measure of community males' sexual interest in MPR with high internal reliability and temporal stability. In a sample of university males we found that a large proportion (66%) did not emphatically reject an interest in MPR. We also found that rape-supportive cognitive distortions, antisocial attitudes, and high-risk sexual fantasies were predictors of sexual interest in MPR. We discuss these findings and the implications for further research employing proclivity measures referencing theory development and clinical practice.

    Full Text Available Introduction. This is a working paper which aims to present the preliminary results of a study into the search behaviour of the general public. The paper reports on the findings of the first six months of an eighteen-month data collection excercise. Method. . Detailed observations were made of nine volunteers, engaged on a variety of search tasks. Some of the tasks were self-selected, others were set by the researchers. Most tasks however, were designed to enable the volunteers to search within their own areas of interest and expertise. Analyses. A set of 'search dimensions' is proposed and qualitative findings based on these are presented. In addition, some initial quantitative findings are discussed. Result. Findings to date suggest that the best search strategy is a combination of simplicity and scrutiny. Volunteers who entered a few search terms but then carefully studied the results, appeared to be more successful than those who attempted to be prescriptive and entered a long series of terms.

    Full Text Available The main topic of the contribution was comparison between retrospective attachment (emocional warmth and rejection and aggressive manifestations (physical aggressivness, verbal aggressivness, anger and hostility among younger adulthood. Bowlby's theory of attachment was that once a core attachment style develops in an infant, it will influence and shape the nature of all intimate relations for the individual moving forward throughout the infant's life cycle. Authors Mikulincer and Shaver (2011 explain how these primary attachment experiences would affect future emotional, cognitive and behavioral processes. Secure adolescents, in comparison to insecure ones are perceived as being less aggressive. Research has pointed out that secure parental attachment promotes adaptive psychological functioning. The direct relationship between attachment security and aggressive/delinquent behaviour is in line with prior evidence that secure adolescents rate higher in terms of emotional and social adjustment, enjoy more positive relationships with their family and peers, and are less likely to engage in externalizing problems, such as antisocial and aggressive behaviours. On the other hand, insecure attachment is connected with aggressive and externalizing behaviour. Hypotheses were formulated on the base of theoretical background and our assumption was, that younger adults with emocional warmth attachment will have lower level of aggressive manifestations (physical aggression, verbal aggression, anger and hostility than younger adults with rejectional attachment. We used two standardized questionnaires for data collection, s.E.M.B.U. Questionnaire, which measured retrospective attachment (emocional warmth and rejection and Questionnaire of Aggressivness, which measured aggressive manifestations. We used statistical analysis and we found statistically significant differencies, which are preliminary findings from broader research, between emocional warmth

    A method for finding integrable four-dimensional symplectic maps is outlined. The method relies on solving for parameter values at which the linear stability factors of the fixed points of the map have the values corresponding to integrability. This method is applied to accelerator lattices in order to increase dynamic aperture. Results show a increase of the dynamic aperture after correction, which implies the validity of the method.

    The study objective was to develop quality measures for adult cochlear implant centers. A modified Delphi design beginning with focus groups of surgeons and audiologists was used, as adapted from the American College of Cardiology / American Heart Association method for creating quality measures. Two academic cochlear implant programs and 1 private program participated. Qualitative focus group analysis yielded 58 candidate measures. An additional 5 candidate measures were added from a systematic review of the literature. After exclusion of pediatric measures, structure measures, and process measures and discussion of details and implications of each measure, 8 measures remained as the preliminary Adult Cochlear Implant Outcome (CI-OUTCOME) Measure Set. This study provides a preliminary set of measures for evaluating the quality of adult cochlear implant centers, based on input from implant surgeons and audiologists. The next step will be to gather feedback from implant patients. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2016.

    Full Text Available One of the key areas being emphasis in ISO 9001 Quality Management System (QMS is performance measurement towards continual improvement. Among the primary measuring tools is quality cost approach. Quality cost has been well practice in manufacturing sector but slowly gain its importance in construction industry. In fact Project Management Body of Knowledge (PMBOK has reckoned quality cost as one of the tool and technique in few of its management processes. In view of such circumstances that has prompted an effort to undertake a study to ascertain the level of knowledge and practice on quality cost in Malaysian construction landscape. The targeted group of respondents was the personnel in the project management team. Capitalizing Construction Industry Development Board (CIDB National Electronic Tendering Initiatives (NETI road shows which were held in year 2007 throughout the country, the author was able to garner 263 respondents representing the project management team. Subsequently the data gathered from the completed forms were analyzed using Statistical Package for Social Science (SPSS software. General findings indicated that the level of knowledge and practice on quality cost among the project management team were relatively low. One of the main contributing factors was poor knowledge in the area related to quality cost. Despite of such scenario most of the respondents showed their interest in acquiring knowledge in the field of quality cost. Hence quality cost approach is at the infancy stage in Malaysian construction industry.

    D-cycloserine (DCS), a partial glutamate N-methyl-D-aspartic acid (NMDA) receptor agonist, enhances extinction of conditioned fear responding in rodents and facilitates exposure-based learning in humans with anxiety disorders. This preliminary study investigates DCS pretreatment on response to cocaine cues in cocaine-dependent subjects. Ten cocaine-dependent subjects were randomly assigned to receive either 50 mg DCS or matching placebo two hours before each of two 1-hour cocaine cue exposure sessions one day apart. HR and craving ratings were obtained before and during cue exposure sessions. There was a trend towards increased craving to cocaine cues in cocaine-dependent individuals after administration of DCS. The administration of DCS prior to cue exposure sessions may facilitate response activation. While facilitation of extinction-based learning by DCS may have therapeutic potential for cocaine dependence, this drug may exhibit a different profile in cocaine-dependent individuals as compared to those with anxiety disorders.

    Despite the many dangers associated with smoking during pregnancy, it remains a salient public health problem for Wisconsin women. The First Breath pilot program was developed in an attempt to reduce rates of smoking during pregnancy among low-income women. Preliminary results suggest that the First Breath counseling-based approach is effective, with a quit rate of 43.8% among First Breath enrollees at 1 month postpartum. Women receiving First Breath cessation counseling also had higher quit rates at every measurement period versus women in a comparison group who were receiving whatever cessation care was available in their county in the absence of First Breath. The First Breath pilot study has demonstrated success in helping pregnant women quit smoking and in creating a model for integration of cessation services into prenatal health care service provision. It is through this success that First Breath is expanding beyond the pilot study stage to a statewide program in 2003.

    1986-10-01

    This article summarizes findings of a fertility sampling survey conducted in April 1985 in the Hebei and Shaanxi provinces and Shanghai, China. Altogether, 13,307 married women of reproductive age were interviewed. The results of the nuptiality section, which surveyed 19,956 women aged 15-49 show that 1) a high marriage rate, a low divorce rate, and a stable marriage relationship exist; 2) during the past 30 years, the number of early marriages has declined remarkably and the median age at marriage has risen; 3) in the past 30 years, the peak age at 1st marriage has risen rapidly for women in Shanghai and Hebei while it has risen relatively slowly for women in Shaanxi; 4) in the past 10 years, the mean age at 1st marriage has increased more than 1 year for Shanghai women, has fluctuated for Shaanxi women, and has decreased for Hebei women; and 5) the total 1st marriage rates were high in the early 1980s, but declined slightly in 1984. Factors which influence nuptiality include 1) education on late marriage, and 2) elimination of arranged marriage. The results of the fertility and infant mortality section show that 1) the number of children ever born has been decreasing year by year, 2) a low proportion of primarily infertile women exists, 3) the parity progressive ratio declined rapidly in Shanghai, but more slowly in Hebei and Shaanxi; 4) infant mortality has declined considerably in the last 25 years, because of improvements in medical and health services; 5) age at 1st birth is increasing; and 6) the magnitude of the rise in median age at 1st birth is smaller than the median age at 1st marriage. During the last 10 years, 1) fertility has declined in both Shaanxi and Hebei; 2) the mean age at childbirth has decreased somewhat; 3) the 1-child policy has won wide response; and 4) among infants born 1980-1983, the mortality rate is 19.3 per 1000 in Shanghai and over 34 per 1000 in both Hebei and Shaanxi. The results of the contraception section show that 1

    A liver tumor 35 mm in diameter was found incidentally in a 40-year-old woman who had no history of liver diseases or the use of oral contraceptives. Radiological diagnostics showed the typical findings of liver cell adenoma (LCA). Dynamic computed tomography revealed that the tumor showed a homogenous enhancement in the arterial phase and almost the same enhancement as the surrounding liver parenchyma in the delayed phase. The tumor was found to contain fat on magnetic resonance imaging. A benign fat containing liver tumor was suggested. However, radiological findings altered, which caused us to suspect that a welldifferentiated hepatocellular carcinoma (HCC) containing fat was becoming dedifferentiated. Partial hepatectomy was performed and the pathological findings showed the typical findings of LCA. This case was an extremely rare LCA, which had no background of risk for LCA and developed the sequential alteration of the radiological findings to suspect well-differentiated HCC.

    History of perinatal complications (PCs) and first degree family history (FH) of psychiatric illness were examined in groups of schizophrenic/schizoaffective (n = 21) and bipolar (n = 10) patients. PCs were significantly more frequent in the schizophrenic and schizoaffective patients than in bipolar patients. An inverse relationship was found between PCs and FH status, with FH-positive patients having significantly fewer PCs than the FH-negative group. This relationship persisted when the bipolar patients were excluded. Findings emphasize the etiological importance of genetics and perinatal events in the psychoses, and support the validity of a familial/sporadic distinction.

    Full Text Available The purpose of this research was to investigate the extent to which small and medium size businesses in the southern region in Malaysia are prepared for ICT adoption. Most of the businesses have now accepted ICT as an important tool to increase its business in the domestic as well as global market place. In future ICT will grow more rapidly in the Malaysian SMEs sectors. In order to increase the effectiveness of ICT, companies can use Internet to present almost unlimited information about their products and services in cyberspace.

    Attention difficulties are a common clinical complaint among children with epilepsy. We aimed to compare a range of attentional abilities between groups of children with two common epilepsy syndromes, Temporal Lobe Epilepsy (TLE) and Idiopathic Generalized Epilepsy (IGE), and to healthy controls. We also investigated whether epilepsy factors (laterality of seizure focus, epilepsy onset, duration, and severity) were related to attentional abilities. Multiple dimensions of attention (selective, sustained, and divided attention and attentional control) were assessed directly with standardized neuropsychological measures in 101 children aged 6-16years (23 children with TLE, 20 with IGE and 58 healthy controls). Attention was also assessed indirectly, via a parent-report measure. Children with TLE performed worse than children with IGE (p=0.013) and healthy controls (pattentional control, but no between-group differences were apparent on tests of other attentional abilities. Compared to healthy controls, greater attention problems were reported by parents of children with TLE (p=0.006) and IGE (p=0.012). Left-hemisphere seizure focus and greater epilepsy severity were associated with poorer attentional control and sustained-divided attention, respectively, but no other epilepsy factors were associated with attentional abilities. These findings suggest that children with localization-related epilepsy, but not generalized epilepsy, may be at risk of deficits in attentional control. Interventions aimed at improving attentional control may be targeted at children with localization-related epilepsy, particularly those with a left-hemisphere seizure focus, who appear to be particularly susceptible to this type of attentional deficit.

    Narcolepsy frequently begins in childhood, and is characterized by excessive daytime sleepiness, with the presence of cataplexy reflecting a more severe phenotype. Narcolepsy may result from genetic predisposition involving deregulation of immune pathways, particularly involving T helper 2 cells (Th2). Increased activation of Th2 cells is usually manifested as allergic conditions such as rhinitis, atopic dermatitis, and asthma. We hypothesized that the presence of allergic conditions indicative of increased Th2 balance may dampen the severity of the phenotype in children with narcolepsy. A retrospective chart review of childhood narcolepsy patients was conducted at three major pediatric sleep centers. Patients were divided into those with narcolepsy without cataplexy (NC-) and narcolepsy with cataplexy (NC+). Demographics, polysomnographic and multiple sleep latency test data, and extraction of information on the presence of allergic diseases such allergic rhinitis, atopic dermatitis, and asthma was performed. There were 468 children identified, with 193 children in NC- group and 275 patients in the NC+ group. Overall, NC+ children were significantly younger, had higher body mass index, and had shorter mean sleep latencies and increased sleep onset rapid eye movement events. The frequency of allergic conditions, particularly asthma and allergic rhinitis, was markedly lower in NC+ (58/275) compared to NC- patients (94/193; P narcolepsy. Current findings further suggest that an increased shift toward T helper 2 cells, as indicated by the presence of allergic conditions, may modulate the severity of the phenotype in childhood narcolepsy, and reduce the prevalence of cataplexy in these patients. © 2015 Associated Professional Sleep Societies, LLC.

    Several kinds of nasal cavity lesions located in the region of the infundibulum on CT. At such time, the visualization of these lesions is very similar. The purpose of this study was to differentially diagnose these nasal cavity lesions through evaluation of the MR findings. In 51 cases of pathologically proven nasal cavity masses which on CT showed infundibular widening, we retrospectively evaluated the MR findings. The cases involved prolapsed antral mucosa from sinusitis(n=15), inverted papilloma(n=10), antrochoanal polyp(n=10), aspergillosis(n=9), and nasal polyp(n=7). All patients underwent both CT and MR. imaging. In all cases, CT findings were similar ; soft tissue masses filling the maxillary sinus and nasal cavity were associated with infundibular widening caused by pressure on the uncinate process, leading to erosion. Differential diagnosis by CT was very difficult ; MR T2 weighted imaging was most effective for differential diagnosis of these nasal cavity masses. Prolapsed antral mucosa showed central inhomogeneous mixed signal intensity, with a peripheral rim of hyperintensity along the sinus wall and nasal component. Antrochoanal polyps showed homogeneous bright signal intensity of the antral and nasal component. Aspergillosis showed central dark signal foci. Inverted papillomas showed mixed intermediate and high intensity mixed with high signal intensity. Nasal polyps showed striation mixed of intermediate and high signal intensity, while nasal polyp showed striation of intermediate and high intensity. On Gd-enhanced T1 weighted images, prolapsed antral mucosa and antrochoanal polyp showed peripheral rim enhancement of the antral and nasal component. In contrast, inverted papilloma and nasal polyp showed intense enhancement of the mass and can be separate from the sinus inflammatory disease. Various nasal cavity masses showing infundibular widening on CT can be differentiated on MR images, especially of these are T2 weighted or contrast enhanced T1

    To correlate the sonographic finding of ill-defined fibroadenoma with the histopathologic findings. Sonographic finding of forty nine surgically proven fibroadenomas were retrospectively correlated with histopathologic findings. We evaluated sonographic findings including the margin, shape, size and the echotexture of fibroadenoma. The histopathologic glandular structure, stromal type of fibroadenoma, type of the surrounding breast tissue and presence of interdigitation between fibroadenoma and the surrounding breast tissue were pathologically reviewed and analyzed statistically. Breast sonography of fibroadenomas demonstrated well-defined margin in 28 (57%) and ill-defined margin in 21 (43%) among 49 lesions. Histopathologically, the glandular structure and type of the surrounding breast tissue were not significantly different between well-defined and ill-defined fibroadenomas. The stromal type of fibroadenoma was sclerotic in 8 (29%) well-defined fibroadenomas while sclerotic in 15 (72%) of 21 ill-defined fibroadenomas,showing difference with a statistical significance between well-defined and ill-defined fibroadenomas (p<0.05). Twenty (71%) of 28 fibroadenomas with well-defined sonographic margins showed well-defined border between mass and the surrounding breast tissue, pathologically. Meanwhile, twenty (95%) of 21 fibroadenomas with ill-defined sonographic margins demonstrated interdigitation of the surrounding breast tissue and mass, exhibiting a statistical significance (p<0.005). Ill-defined margins of fibroadenomas on sonography represent the interdigitation of the surrounding breast tissue with a mass and is seen in the sclerotic stromal type of fibroadenomas.

  13. A phenomenographic investigation into Information Literacy in nursing practice - preliminary findings and methodological issues.

    Forster, Marc

    2013-10-01

    Information Literacy is essential to 'evidence-based practice'; without the ability to locate evidence, evidence-based practice is rendered extremely difficult if not impossible. There is currently little evidence to show how Information Literacy is experienced by nurses or what its parameters are within evidence-based practice and therefore whether Information Literacy educational interventions are actually promoting the correct knowledge and skills. Using phenomenographic interviews the author will attempt to discover how nurses experience Information Literacy. Insights from the findings will be used to map out its parameters and to put forward a theoretical model for a course or module to develop it effectively. This article presents preliminary findings, including 7 draft categories of description of how Information Literacy is experienced in nursing. This pilot study indicates that the complete findings may be of significant potential value in the promotion and development of Information Literacy education in nursing. It is argued that such insights into how nurses actually experience the phenomenon of Information Literacy can be used to develop potentially more effective, research-based, educational interventions.

    2015-01-01

    We compared personality traits of 27 persons with multiple substance dependence with personality data of 52 alcohol-dependent persons regarding their personality traits and disorders (obtained by using SCID-II, TCI and NEO FFI). Both patient groups were free of any other mental disorder. In SKD-II, we found significant differences in the male group in dependent and scizotypic personality disorder. There were no significant differences in the female group, but sample was very small. We also found significant differences between alcohol-dependent and multiple substance-dependent persons in extraversion and novelty seeking. We detected significant differences in personality disorders evaluated by SCID-II. Temperament and character items—as evaluated by NEO FFI and TCI—showed also significant differences in personality traits. Given the limited number of subjects, the data should be regarded as preliminary until replicated in a larger sample. Nevertheless, the findings may be of clinical relevance with respect to prognosis or individualized treatment. These findings should be treated with caution until replicated.

  16. Assessment of the contralesional corticospinal tract in early-onset pediatric hemiplegia: Preliminary findings.

    Hawe, Rachel L; Dewald, Jules P A

    2014-01-01

    While pediatric hemiplegia results from a unilateral lesion, the immature state of the brain at the time of injury increases the likelihood of observing changes in the non-lesioned hemisphere as well. The purpose of this preliminary study was to use diffusion tensor imaging to evaluate the contralesional corticospinal tracts in individuals with early-onset pediatric hemiplegia. Twelve individuals with pediatric hemiplegia and ten age-matched controls underwent diffusion tensor imaging (DTI). Corticospinal projections were reconstructed using probabilistic tractography for both the lesioned and contralesional side in pediatric hemiplegia as well as the dominant and non-dominant sides in control subjects. The contralesional tract was found to have decreased white matter integrity relative to control subjects. Compared to controls, the contralesional tract also showed increased tract volume. The increase in volume suggests the presence of ipsilateral corticospinal projections from the contralesional hemisphere that are maintained during development to control the paretic extremities. Decreases in integrity may be explained by diffuse damage or incomplete maturation. The findings of this study support the notion of bilateral motor involvement in pediatric hemiplegia, and the need to address bilateral neural changes as well as motor deficits in this population.

    2008-01-01

    Based on findings in traumatized animals and patients with posttraumatic stress disorder, and on traumatogenic models of complex dissociative disorders, it was hypothesized that (1) patients with complex dissociative disorders have smaller volumes of hippocampus, parahippocampal gyrus, and amygdala than normal controls, (2) these volumes are associated with severity of psychoform and somatoform dissociative symptoms, and (3) patients who recovered from dissociative identity disorder (DID) have more hippocampal volume that patients with florid DID. The preliminary findings of the study are supportive of these hypotheses. Psychotherapy for dissociative disorders may affect hippocampal volume, but longitudinal studies are required to document this potential causal relationship.

    Full Text Available We report a case of a 33-year-old male with a mixed germ-cell testicular tumor. Postoperative follow-up FDG-PET revealed concentration of FDG in the left inguinal area which is not tumor metastasis or local recurrence but suture reactivity granuloma. In this paper, we reviewed suture granulomas associated with false-positive findings on FDG-PET after surgery. If FDG-PET will be used more frequently in the future, it will be necessary to refrain from using silk thread in order to prevent any unnecessary surgery.

    This paper reports on preliminary findings on a study of the relationship of growth and profitability among small privately held Finnish Life Science firms. Previous research results concerning growth and profitability are mixed, ranging from strongly positive to a negative relationship. The conventional wisdom states that growth is a prerequisite for profitability. Our results suggest that the reverse is the case. A high profitability-low growth biotech firm is more probably to make the transition to high profitability-high growth than a firm that starts off with low profitability and high growth.

    Full Text Available The traditional general procurement route found in many housing projects in Malaysia is conceptualized as a governance structure following the transaction cost economics (TCE approach. This approach has been used to examine governance structures in different economic sectors in several countries but evidence of its use in the context of developing countries is limited. This lack of evidence has prompted the authors to conduct a preliminary study to ascertain whether a TCE approach can explain construction governance structures in developing countries. This research does not discuss the trade-off that governs the choice of hybrids, market or hierarchies for organizing transactions. Rather, it takes advantage of existing research to substantiate the specific properties of hybrid organizations as governance structures. The main focus is coordination. Coordination is specified at two levels. At Level 1 is the coordination of specialization (i.e. the formation of the project team members and at Level 2 is the coordination mode of the contracting parties (client and contractor and the agents involved (the lead designer and project manage r. A case survey method was adopted. Preliminary findings seem to suggest that clients have used hierarchical themes in the contracts and high powered incentives to coordinate with in the contracting parties. The research findings suggest that all participants involved in the sample studied used governance structures symptomatic of a hybrid organization.

    2012-09-01

    Regardless of cost and performance some wind projects are unable to proceed to commissioning as a result of deployment barriers. Principal deployment barriers in the industry today include: wildlife, public acceptance, access to transmission, and radar. To date, methods for understanding these non-technical barriers have failed to accurately characterize the costs imposed by deployment barriers and the degree of impact to the industry. Analytical challenges include limited data and modeling capabilities. Changes in policy and regulation, among other factors, also add complexity to analysis of impacts from deployment barriers. This presentation details preliminary results from new NREL analysis focused on quantifying the impact of deployment barriers on the wind resource of the United States, the installed cost of wind projects, and the total electric power system cost of a 20% wind energy future. In terms of impacts to wind project costs and developable land, preliminary findings suggest that deployment barriers are secondary to market drivers such as demand. Nevertheless, impacts to wind project costs are on the order of $100/kW and a substantial share of the potentially developable windy land in the United States is indeed affected by deployment barriers.

    Preliminary comprehensive analyses of quantitative and qualitative employment effects of selected solar and conventional energy systems are presented. It proposes a framework for analyzing the direct, indirect, induced, displacement, disposable income, and qualitative employment effects of alternative energy systems. The analyses examine current research findings on these effects for a variety of solar and conventional energy sources and compare expected employment impacts. In general, solar energy systems have higher direct and indirect employment requirements than do conventional energy systems. In addition, employment displaced from conventional sources and employment effects due to changes in consumers' disposable income are highly significant variables in net employment comparisons. Analyses of the size and location of projected energy developments suggest that dispersed solar energy systems have a more beneficial impact on host communities than do large conventional facilities, regardless of the relative magnitude of employment per unit of energy output.

    This article presents preliminary findings from the first participant to complete an experiment assessing the efficacy of the personal stereo in treating auditory hallucinations. O.C., a 50-year-old woman, took part in a controlled treatment trial in which 1-week baseline, personal stereo, and control treatment (nonfunctioning hearing aid) stages were alternated for 7 weeks. The Positive and Negative Syndrome Scale, Clinical Global Impression Scales, Beliefs About Voices Questionnaire, Rosenberg Self-Esteem Scale, and Topography of Voices Rating Scale were used. The personal stereo led to a decrease in the severity of O.C.'s auditory hallucinations. For example, she rated her voices as being fairly distressing during baseline and control treatment stages but neutral during personal stereo stages. A slight decrease in other psychopathology also occurred during personal stereo stages. Use of the personal stereo did not lead to a decrease in self-esteem, contradicting suggestions that counterstimulation treatments for auditory hallucinations may be disempowering.

  5. Parents and Teachers‘ Voices of Quality Preschool: Preliminary findings from Indonesia

    2015-11-01

    Full Text Available This paper describes preliminary findings of a study on Indonesian teachers and parents’ perspectives of quality preschool program. It departs in one hand from the context of the Indonesian government massive promotion of early childhood programs and on the other hand of the country top-down, government-dominated quality system. Moreover, it is contextualized within the growing body of literatures, which emphasizes the centrality of quality issues to early childhood service and the notion that quality is a complex, contextual, multifaceted construction and idea. This study found that even though parents and teachers’ constructions of quality share some commonalities with those of the government-constructed ones, they significantly differ. The government-constructed quality framework for example emphasizes on teacher formal qualification, but teachers and parents have moved beyond such formality and urged the importance of teacher personal character

  6. Investigating feedback mechanisms between stress and grain-size: preliminary findings from finite-element modelling

    It is widely accepted that changes in stress and grain size can induce a switch between grain-size insensitive (GSI) and sensitive (GSS) creep mechanisms. Under steady-state conditions, grains evolve to an equilibrium size in the boundary region between GSS and GSI, described by the paleopiezometer for a given material. Under these conditions, significant rheological weakening is not expected, as grain size reduction processes are balanced by grain growth processes. However, it has been shown that the stress field surrounding faults varies through the seismic cycle, with both rapid loading and unloading of stress possible in the co- and post-seismic stages. We propose that these changes in stress in the region of the brittle-ductile transition zone may be sufficient to force a deviation from the GSI-GSS boundary and thereby cause a change in grain size and creep mechanism prior to system re-equilibration. Here we present preliminary findings from numerical modelling of stress and grain size changes in response to loading of mechanical inhomogeneities. Our results are attained using a grain-size evolution (GSE) subroutine incorporated into the SULEC finite-element code developed by Susan Ellis and Susanne Buiter, which utilises an iterative approach of solving for spatial and temporal changes in differential stress, grain size and active creep mechanism. Preliminary models demonstrate that stress changes in response to the opening of a fracture in a flowing medium can be significant enough to cause a switch from GSI to GSS creep. These results are significant in the context of understanding spatial variations and feedback between stress, grain size and deformation mechanisms through the seismic cycle.

    Furazolidone induces a cardiotoxicosis when fed in toxic concentrations to newly hatched ducklings. This preliminary experiment was designed to determine if creatine kinase (CK) isoenzymic activities or other serum analytes would be useful as indicators of these cardiac alterations. Sera from 12 ducklings (six fed a control ration and six fed the control ration with 700 mg furazolidone added per kg of feed [700 ppm] for 28 days) were analyzed for CK isoenzymic activities, electrolytes, nitrogenous metabolites, hepatic enzymic activities, bilirubin, and glucose. Statistically significant differences between control and treated groups were detected for creatine kinase MB (CK-MB, cardiac muscle origin) isoenzymic activity and bilirubin, potassium, calcium, and total carbon dioxide concentrations. Differences other than CK-MB isoenzymic activity were generally explained by factors related to the toxicosis or sample handling. These findings suggest that CK-MB isoenzymic activity may be useful to detect and monitor the progress of cardiac injury in furazolidone toxicosis, thereby increasing the usefulness of this model of dilated cardiomyopathy. Our findings, analyzed on the Kodak Ektachem 700 Dry Chemistry Analyzer, are compared with serum chemistry values reported in the literature.

    This study examined patterns of neural response to feedback received during simulated interpersonal interactions in adolescents with anxiety disorders and healthy peers. To this aim, behavioral and neural responses during the Prisoner’s Dilemma (PD) game, an economic exchange task, were compared between adolescents with anxiety disorders (N=12) and healthy controls (n=17). Participants were deceived to believe that their co-player (a pre-programmed computer algorithm) was another study participant. Anxious participants and controls differed significantly in patterns of neural activation in the medial prefrontal cortex (mPFC), ACC, precuneus, insula, and temporoparietal junction (TPJ) when receiving feedback about co-player defection or cooperation. Groups also differed significantly in post-feedback behavior; specifically anxious adolescents were more likely than controls to cooperate following trials when the co- player betrayed them. Our findings provide preliminary evidence that, in social situations, anxious adolescents may not only behave differently than healthy peers, but they may also engage neural resources in different ways. These findings constitute a first step toward elucidating mechanisms underlying social impairment in youth with internalizing disorders. PMID:21516543

    2013-05-01

    In a rural village located near San Miguel de Allende in the State of Guanajuato, Mexico, lung cancer is the primary cause of death. Medical and mortality records show that near to 40% of the deaths correspond to different neoplasms of the lung and near to 10% to malignant mesothelioma. Epidemiological and environmental surveys are conducted to provide insight into the causes of this health problem. Erionite was found in altered volcanic tuffs nearby the village and in fine-granular materials used for the construction of adobe houses in the past. Preliminary results relate erionite fibers as the main carcinogenic agent with almost the same annual rate of deaths by mesothelioma than in the Cappadocian region of Turkey.

    2015-12-01

    Full Text Available Abstract Objective: The present study was aimed at investigating bone involvement secondary to rotator cuff calcific tendonitis at ultrasonography. Materials and Methods: Retrospective study of a case series. The authors reviewed shoulder ultrasonography reports of 141 patients diagnosed with rotator cuff calcific tendonitis, collected from the computer-based data records of their institution over a four-year period. Imaging findings were retrospectively and consensually analyzed by two experienced musculoskeletal radiologists looking for bone involvement associated with calcific tendonitis. Only the cases confirmed by computed tomography were considered for descriptive analysis. Results: Sonographic findings of calcific tendinopathy with bone involvement were observed in 7/141 (~ 5% patients (mean age, 50.9 years; age range, 42-58 years; 42% female. Cortical bone erosion adjacent to tendon calcification was the most common finding, observed in 7/7 cases. Signs of intraosseous migration were found in 3/7 cases, and subcortical cysts in 2/7 cases. The findings were confirmed by computed tomography. Calcifications associated with bone abnormalities showed no acoustic shadowing at ultrasonography, favoring the hypothesis of resorption phase of the disease. Conclusion: Preliminary results of the present study suggest that ultrasonography can identify bone abnormalities secondary to rotator cuff calcific tendinopathy, particularly the presence of cortical bone erosion.

    Two 9-year-old patients with femoral bone lesions were referred to the authors' institution within a few days of each other. Both showed similar radiographic, magnetic resonance imaging, and scintigraphic findings. The radiographs showed osteolytic lesions in the right femoral diaphyses, and gadolinium-DTPA-enhanced magnetic resonance imaging revealed inhomogeneous enhancement. Tc-99m HMDP showed marked linear accumulation with relatively low central uptake in the right femoral shafts, and TI-201 scintigraphy showed considerable uptake corresponding to the area seen with Tc-99m HMDP. Histologic analysis confirmed eosinophilic granuloma in the first patient and Brodie's abscess in the second. The radiographic and scintigraphic findings in Brodie's abscess may be similar to those in eosinophilic granuloma.

    During the last several years, the amount of wireless network traffic data increased fast and relative technologies evolved rapidly. In order to improve the performance and Quality of Experience (QoE) of wireless network services, the analysis of field network data and existing delivery mechanisms comes to be a promising research topic. In order to achieve this goal, a smartphone based platform named Monitor and Diagnosis of Mobile Applications (MDMA) was developed to collect field data. Based on this tool, the web browsing service of High Speed Downlink Packet Access (HSDPA) network was tested. The top 200 popular websites in China were selected and loaded on smartphone for thousands times automatically. Communication packets between the smartphone and the cell station were captured for various scenarios (e.g. residential area, urban roads, bus station etc.) in the selected city. A cross-layer database was constructed to support the off-line analysis. Based on the results of client-side experiments and analysis, the usability of proposed portable tool was verified. The preliminary findings and results for existing web browsing service were also presented.

    Full Text Available This paper presents the preliminary findings of an ongoing research project focused on the importance of building learning tools and procedures that will help media professionals adjust to a constant changing environment. Adopting a mix of quantitative and qualitative methodology by conducting in depth interviews with journalists from Greece and Cyprus, and by running an online questionnaire, addressed to journalists as well as communication professionals, we try to define the role and the profile of the contemporary journalist, and how it has changed under the pressure and the potential, unleashed by new technologies and the global financial crisis. We study the development of lifelong learning programs, their impact and their results with an emphasis on distance learning. Through our research we conclude that there is a need to rethink journalism training and curricula by introducing new skills. In addition, lifelong learning in the form of distance learning seems to be a priority for most journalists in order to adjust to the current media landscape.

    Energy information systems comprise software, data acquisition hardware, and communication systems that are intended to provide energy information to building energy and facilities managers, financial managers, and utilities. This technology has been commercially available for over a decade, however recent advances in Internet and other information technology, and analytical features have expanded the number of product options that are available. For example, features such as green house gas tracking, configurable energy analyses and enhanced interoperability are becoming increasingly common. Energy information systems are used in a variety of commercial buildings operations and environments, and can be characterized in a number of ways. Basic elements of these systems include web-based energy monitoring, web-based energy management linked to controls, demand response, and enterprise energy management applications. However the sheer number and variety of available systems complicate the selection of products to match the needs of a given user. In response, a framework was developed to define the capabilities of different types of energy information systems, and was applied to characterize approximately 30 technologies. Measurement is a critical component in managing energy consumption and energy information must be shared at all organizational levels to maintain persistent, efficient operations. Energy information systems are important to understand because they offer the analytical support to process measured data into information, and they provide the informational link between the primary actors who impact building energy efficiency - operators, facilities and energy managers, owners and corporate decision makers. In this paper, preliminary findings are presented, with a focus on overall trends and the general state of the technology. Key conclusions include the need to further pursue standardization and usability, x-y plotting as an under-supported feature, and

    Reward learning has been postulated as a critical component of hedonic functioning that predicts depression risk. Reward learning deficits have been established in adults with current depressive disorders, but no prior studies have examined the relationship of reward learning and depression in children. The present study investigated reward learning as a function of familial depression risk and current diagnostic status in a pediatric sample. The sample included 204 children of parents with a history of depression (n = 86 high-risk offspring) or parents with no history of major mental disorder (n = 118 low-risk offspring). Semistructured clinical interviews were used to establish current mental diagnoses in the children. A modified signal detection task was used for assessing reward learning. We tested whether reward learning was impaired in high-risk offspring relative to low-risk offspring. We also tested whether reward learning was impaired in children with current disorders known to blunt hedonic function (depression, social phobia, PTSD, GAD, n = 13) compared to children with no disorders and to a psychiatric comparison group with ADHD. High- and low-risk youth did not differ in reward learning. However, youth with current anhedonic disorders (depression, social phobia, PTSD, GAD) exhibited blunted reward learning relative to nondisordered youth and those with ADHD. Our results are a first demonstration that reward learning deficits are present among youth with disorders known to blunt anhedonic function and that these deficits have some degree of diagnostic specificity. We advocate for future studies to replicate and extend these preliminary findings. © 2015 Wiley Periodicals, Inc.

    Vestibular and ocular motor impairments and symptoms have been documented in patients with sport-related concussions. However, there is no current brief clinical screen to assess and monitor these issues. To describe and provide initial data for the internal consistency and validity of a brief clinical screening tool for vestibular and ocular motor impairments and symptoms after sport-related concussions. Cross-sectional study; Level of evidence, 2. Sixty-four patients, aged 13.9 ± 2.5 years and seen approximately 5.5 ± 4.0 days after a sport-related concussion, and 78 controls were administered the Vestibular/Ocular Motor Screening (VOMS) assessment, which included 5 domains: (1) smooth pursuit, (2) horizontal and vertical saccades, (3) near point of convergence (NPC) distance, (4) horizontal vestibular ocular reflex (VOR), and (5) visual motion sensitivity (VMS). Participants were also administered the Post-Concussion Symptom Scale (PCSS). Sixty-one percent of patients reported symptom provocation after at least 1 VOMS item. All VOMS items were positively correlated to the PCSS total symptom score. The VOR (odds ratio [OR], 3.89; P VMS (OR, 3.37; P VMS, NPC distance, and ln(age) that resulted in a high predicted probability (area under the curve = 0.89) for identifying concussed patients. The VOMS demonstrated internal consistency as well as sensitivity in identifying patients with concussions. The current findings provide preliminary support for the utility of the VOMS as a brief vestibular/ocular motor screen after sport-related concussions. The VOMS may augment current assessment tools and may serve as a single component of a comprehensive approach to the assessment of concussions. © 2014 The Author(s).

    An exploratory study to better understand the "networked" life of the medical school as a learning environment. In a recent academic year, the authors gathered data during two six-week blocks of a sequential histology and anatomy course at a U.S. medical college. An eight-item questionnaire captured different dimensions of student interactions. The student cohort/network was 48 first-year medical students. Using social network analysis (SNA), the authors focused on (1) the initial structure and the evolution of informal class networks over time, (2) how informal class networks compare to formal in-class small-group assignments in influencing student information gathering, and (3) how peer assignment of professionalism role model status is shaped more by informal than formal ties. In examining these latter two issues, the authors explored not only how formal group assignment persisted over time but also how it functioned to prevent the tendency for groupings based on gender or ethnicity. The study revealed an evolving dynamic between the formal small-group learning structure of the course blocks and the emergence of informal student networks. For example, whereas formal group membership did influence in-class questions and did prevent formation of groups of like gender and ethnicity, outside-class questions and professionalism were influenced more by informal group ties where gender and, to a much lesser extent, ethnicity influence student information gathering. The richness of these preliminary findings suggests that SNA may be a useful tool in examining an array of medical student learning encounters.

    Full Text Available BACKGROUND: Depression is associated with an unusually high rate of aging-related illnesses and early mortality. One aspect of "accelerated aging" in depression may be shortened leukocyte telomeres. When telomeres critically shorten, as often occurs with repeated mitoses or in response to oxidation and inflammation, cells may die. Indeed, leukocyte telomere shortening predicts early mortality and medical illnesses in non-depressed populations. We sought to determine if leukocyte telomeres are shortened in Major Depressive Disorder (MDD, whether this is a function of lifetime depression exposure and whether this is related to putative mediators, oxidation and inflammation. METHODOLOGY: Leukocyte telomere length was compared between 18 unmedicated MDD subjects and 17 controls and was correlated with lifetime depression chronicity and peripheral markers of oxidation (F2-isoprostane/Vitamin C ratio and inflammation (IL-6. Analyses were controlled for age and sex. PRINCIPAL FINDINGS: The depressed group, as a whole, did not differ from the controls in telomere length. However, telomere length was significantly inversely correlated with lifetime depression exposure, even after controlling for age (p<0.05. Average telomere length in the depressed subjects who were above the median of lifetime depression exposure (≥9.2 years' cumulative duration was 281 base pairs shorter than that in controls (p<0.05, corresponding to approximately seven years of "accelerated cell aging." Telomere length was inversely correlated with oxidative stress in the depressed subjects (p<0.01 and in the controls (p<0.05 and with inflammation in the depressed subjects (p<0.05. CONCLUSIONS: These preliminary data indicate that accelerated aging at the level of leukocyte telomeres is proportional to lifetime exposure to MDD. This might be related to cumulative exposure to oxidative stress and inflammation in MDD. This suggest that telomere shortening does not antedate depression

    Full Text Available Abstract Here we report preliminary findings from a small-sample functional magnetic resonance imaging (fMRI study of healthy adolescents who completed a working memory task in the context of a chronic sleep restriction experiment. Findings were consistent with those previously obtained on acutely sleep-deprived adults. Our data suggest that, when asked to maintain attention and burdened by chronic sleep restriction, the adolescent brain responds via compensatory mechanisms that accentuate the typical activation patterns of attention-relevant brain regions. Specifically, it appeared that regions that are normally active during an attention-demanding working memory task in the well-rested brain became even more active to maintain performance after chronic sleep restriction. In contrast, regions in which activity is normally suppressed during such a task in the well-rested brain showed even greater suppression to maintain performance after chronic sleep restriction. Although limited by the small sample, study results provide important evidence of feasibility, as well as guidance for future research into the functional neurological effects of chronic sleep restriction in general, the effects of sleep restriction in children and adolescents, and the neuroscience of attention and its disorders in children.

    Cytogenetic indicators are widely used in radiobiology to evaluate effects of ionizing radiation since dicentric chromosomes (Dic) are almost exclusively induced by ionizing radiation, and spontaneous frequency of Dic is very low in the healthy general population (about one Dic per 1000 cells). A particular interest of biodosimetry has been not only to obtain absorbed dose estimates using adequate calibration curves, under the assumption that all individuals respond equally to radiation-induced chromosome aberrations, but also to find a way to demonstrate inter-individual radiosensitivity and a possible correlation with age and gender. Thus, the objective of this preliminary work was the evaluation of the influence of age and gender on the outcome of cytogenetic biomarkers after {gamma}-irradiation. Samples of peripheral blood lymphocytes from six healthy, non-smoker, donors from both genders (three men and three women), in the range of 20 to 49 years, were irradiated with doses from 0 Gy to 3 Gy air kerma, using a {sup 60}Co gamma rays source with a dose rate from 170-180 mGy/min. A clear dose-dependent increase in terms of aberrant cells excluding gaps (ACEG) and Dic was observed for all donors. Our preliminary results suggest, in the higher dose level evaluated (3 Gy), a larger intervariability among individuals for Dic, with females apparently more sensitive than males (P<0.05). Considering the different age groups, male donors showed a decrease, with age, for Dic and ACEG at the higher dose and also, for the background level, in case of ACEG. Future work will consider the study of more individuals, from both genders and different ages, in order to verify if this tendency persists and to enable the implementation of a dose-response calibration curve at Instituto Tecnologico e Nuclear for the Portuguese population, to quantify the biological dose in case of a radiological accident or emergency.

    Brain-derived neurotrophic factor (BDNF) signaling pathways have been shown to be essential for opioid-induced plasticity. We conducted an exploratory study to evaluate BDNF variability in opioid addict responders and nonresponders to methadone maintenance treatment (MMT). We analyzed 21 single nucleotide polymorphisms (SNPs) across the BDNF genomic region. Responders and nonresponders were classified by means of illicit opioid consumption detected in random urinalysis. Patients were assessed by a structured interview (Psychiatric Research Interview for Substance and Mental Disorders (PRISM)-DSM-IV) and personality was evaluated by the Cloninger's Temperament and Character Inventory. No clinical, environmental and treatment characteristics were different between the groups, except for the Cooperativeness dimension (P < 0.001). Haplotype block analysis showed a low-frequency (2.7%) haplotype (13 SNPs) in block 1, which was more frequent in the nonresponder group than in the responder group (4/42 vs. 1/135; P(corrected) = 0.023). Fine mapping in block 1 allows us to identify a haplotype subset formed by only six SNPs (rs7127507, rs1967554, rs11030118, rs988748, rs2030324 and rs11030119) associated with differential response to MMT (global P sim = 0.011). Carriers of the CCGCCG haplotype had an increased risk of poorer response, even after adjusting for Cooperativeness score (OR = 20.25 95% CI 1.46-280.50, P = 0.025). These preliminary results might suggest the involvement of BDNF as a factor to be taken into account in the response to MMT independently of personality traits, environmental cues, methadone dosage and psychiatric comorbidity.

    Conclusion: In this preliminary study of patients undergoing multilevel lumbar lamienctomies with posterolateral noninstrumented fusions, results were nearly comparable utilizing Vitoss or NanOss as bone graft expanders. Although the number of NanOss patients was substantially lower, the comparable efficacy and absence of postoperative complications for noninstrumented fusions is promising.

    The purpose of this study was to characterize the neurophysiological and clinical effects that may result from the neuro emotional technique (NET) in patients with traumatic stress symptoms associated with a cancer-related event. We hypothesized that self-regulatory processing of traumatic memories would be observable as physiological changes in key brain areas after undergoing the NET intervention and that these changes would be associated with improvement of traumatic stress symptoms. We enrolled 23 participants with a prior cancer diagnosis who expressed a distressing cancer-related memory that was associated with traumatic stress symptoms of at least 6 months in duration. Participants were randomized to either the NET intervention or a waitlist control condition. To evaluate the primary outcome of neurophysiological effects, all participants received functional magnetic resonance imaging (fMRI) during the auditory presentation of both a neutral stimulus and a description of the specific traumatic event. Pre/post-comparisons were performed between the traumatic and neutral condition, within and between groups. Psychological measures included the Impact of Event Scale (IES), State Trait Anxiety Index (STAI), Brief Symptom Inventory (BSI)-18, and Posttraumatic Cognitions Inventory (PTCI). The initial fMRI scans in both groups showed significant increases in the bilateral parahippocampus and brainstem. After NET, reactivity in the parahippocampus, brainstem, anterior cingulate, and insula was significantly decreased during the traumatic stimulus. Likewise, participants receiving the NET intervention had significant reductions (p < 0.05) compared to the control group in distress as measured by the BSI-18 global severity index, anxiety as measured by the STAI, and traumatic stress as measured by the IES and PTCI. This study is an initial step towards understanding mechanistic features of the NET intervention. Specifically, brain regions involved with traumatic

    -density, finer grain-size characteristics, and possibly higher total phosphorous (TP) content, when compared against soils from nearby uncontaminated areas. Approximately 250 pairs of (contaminated and uncontaminated) soil samples were obtained from nine different sub-catchments located in four different European countries; namely, France, Germany, Switzerland and the UK. Sample pairs were sub-divided into contaminated & uncontaminated soils and each variable was subjected to a pair-wise statistical test; firstly for all catchments combined, and then on a catchment-by-catchment basis, to determine whether differences were significant. In addition to the above analyses, further evidence of spatial and topographic colonisation tendencies was sought from digital imagery captured using a remotely-controlled drone (quadcopter) flown along a ca. 1.0 km section of contaminated river corridor. Images were georeferenced, displayed together in a Geographic Information System (GIS) and used to construct a 3-dimensional digital elevation model (DEM). The DEM was interrogated to determine the presence / absence of colonisation trends (i.e. a tendency to colonise low-lying areas). This communication reports preliminary findings from this ongoing work and discusses key implications and possible future directions.

    The objective of this study is to determine the prevalence of lifetime exposure to traumatic events and its relation to PTSD symptoms. Participants were randomly selected from several schools located in the city of Kuching. There were 85 adolescents participating in this study, with ages ranging from 13 to 14 years old, of whom 31% (n=26) were males and 69% (n=59) females. The Child Posttraumatic Stress Index-Revised, The Harvard Trauma Questionnaire and a lifetime trauma checklist were used in this study. Results showed that 77.6% of participants were exposed to at least one lifetime trauma. The most frequently reported traumas were road accident (20.1%), death of a family member (19.7%), and almost drowning (10%). There was more indirect trauma than direct trauma exposure. Males were more likely to be involved in traumatic events than females. Results showed that 7.1% (6) exhibited PTSD symptoms. There was no significant difference in the mean score of CPTS-RI between genders and among ethnic groups. Total exposure to traumatic events was significantly correlated with PTSD symptoms. Findings suggest that number of lifetime traumatic events was quite high and multiple exposures to traumatic events were significantly related to PTSD symptoms. Copyright © 2014 Elsevier B.V.

    The relationship between spirituality and personality in patients with depression is complex and not much explored. The aim of our study is to examine the interconnection between the spiritual quality of life (QoL) and Cloninger's psychobiological model of personality in patients with depression. The sample consisted of 85 consecutive outpatients treated for depression. The measurements used were: Beck Depression Inventory, WHO-Quality of Life-Spiritual, Religious, Personal Beliefs, and Temperament and Character Inventory. The results have shown that higher harm avoidance, lower self-directedness and lower cooperativeness are personality dimensions associated with depression. The spiritual QoL has showed to play a significant role in depression, just as it has proved to be a unique predictor of lower depressive symptoms, adjusted for personality dimensions. The spiritual QoL itself is predicted by personality dimensions, self-directedness and self-transcendence implying that spirituality is a broader construct than the character dimension. Our findings may contribute to a more comprehensive understanding of depression, spirituality and personality.

    Hemostatic factors may be involved in bone health. The present preliminary study investigated the association between plasma fibrinogen and bone mineral density (BMD) in perimenopausal women. A significant inverse correlation between fibrinogen and BMD was observed (correlation coefficient = -0.42, p high level of high-sensitivity C-reactive protein than in that with a low level of high-sensitivity C-reactive protein, and in the subgroup with a high level of diacron reactive oxygen metabolites (an oxidative stress marker) than in that with a low level of diacron reactive oxygen metabolites. Thus, fibrinogen may be a possible marker of BMD in this population. More studies on the associations among hemostasis, inflammation, oxidative stress, and bone metabolism are warranted in the clinical setting.

    Neuroradiological and metabolic imaging is a fundamental diagnostic procedure in the assessment of patients with primary and metastatic brain tumors. The correlation between objective parameters capable of quantifying the neoplastic angioarchitecture and imaging data may improve our understanding of the underlying physiopathology and make it possible to evaluate treatment efficacy in brain tumors. Only a few studies have so far correlated the quantitative parameters measuring the neovascularity of brain tumors with the metabolic profiles measured by means of amino acid uptake in positron emission tomography (PET) scans. Fractal geometry offers new mathematical tools for the description and quantification of complex anatomical systems, including microvascularity. In this study, we evaluated the microvascular network complexity of six cases of human glioblastoma multiforme quantifying the surface fractal dimension on CD34 immunostained specimens. The microvascular fractal dimension was estimated by applying the box-counting algorithm. As the fractal dimension depends on the density, size and shape of the vessels, and their distribution pattern, we defined it as an index of the whole complexity of microvascular architecture and compared it with the uptake of (11)C-methionine (MET) assessed by PET. The different fractal dimension values observed showed that the same histological category of brain tumor had different microvascular network architectures. Fractal dimension ranged between 1.19 and 1.77 (mean: 1.415+/-0.225), and the uptake of (11)C-methionine ranged between 1.30 and 5.30. A statistically significant direct correlation between the microvascular fractal dimension and the uptake of (11)C-methionine (p=0.02) was found. Our preliminary findings indicate that that vascularity (estimated on the histologic specimens by means of the fractal dimension) and (11)C-methionine uptake (assessed by PET) closely correlate in glioblastoma multiforme and that microvascular

The relationship of traumatic life events (including loss and mental health has been investigated. Methods: The sampling of the collaborative study (HKMMS: Hong Kong Mental Morbidity Survey adopts a multi-stage stratification approach with the distribution of residential premises in different geographical districts and the relative proportion of private versus public housing units taken into consideration. In Phase I of this study, 4,644 adults were screened for PTSD with the Trauma Screening Questionnaire (TSQ and Life Event Checklist (LEC, Beck's scales and CIS-R (Revised Clinical Interview Schedule. In Phase II of the study, clinical psychologists conducted the Structured Clinical Interview for DSM Disorders (SCID for 92 participants (results not reported here. Results: Among Phase I participants, 65% reported traumatic experience (including 18% who reported personal experience of sudden death of significant others. Age and gender make a difference in traumatic experience. When compared to participants who reported no traumatic experience in the past, participants who reported to have personal experience of sudden death of significant others or other traumatic experiences were found to have higher TSQ scores, higher psychological distress, lower social support (PSS: Multidimensional Scale of Perceived Social Support, and lower life functioning (SOFAS: Social and Occupational Functioning Assessment Scale, p<0.001. Findings of hierarchical regression showed that type of trauma (i.e., loss, other trauma, or no trauma contributed significantly to the prediction of all the mental health indices after demographic and social variables were controlled. Conclusions: Public education on the association of traumatic experience and psychological health, as well as the monitoring of mental health

    Objective: The diagnosis of acute pyelonephritis in children remains a clinical challenge. It may cause permanent renal scar formation and results in the chronic renal failure if prompt diagnosis and treatment are delayed. The purpose of this study is to compare magnetic resonance imaging (MRI) and renal cortical scintigraphy (RCS) findings in childhood acute pyelonephritis and to determine pyelonephritic foci in the acute phase. Materials and method: Twenty children (15 females and five males) with symptoms dysuria, enuresis, costovertebral pain, fever of 37.5 degree sign C or more and/or positive urine culture were imaged by unenhanced turbo spin echo T2, spin echo T1-weighted, pre- and post-gadolinium inversion recovery MRI and RCS. Both imaging techniques were read independently by two radiologists and nuclear medicine specialists. Sensitivity and specificity of MRI in detecting acute pyelonephritic foci and scar lesions were calculated. Furthermore, in order to calculate the reliability of MRI over RCS in differentiating scar tissue and acute pyelonephritic foci, follow-up MRI studies were done in six patients after treatment of acute pyelonephritis. Results: Sensitivity and specificity of MRI in the detection of pyelonephritic lesions were found to be 90.9 and 88.8%, respectively. There is no statistically significant difference in lesion detection between the two diagnostic modalities (P>0.05). Conclusion: Post-gadolinium MR images show significant correlation with RCS in the determination of renal pathology. Moreover, the ability of discriminating acute pyelonephritic foci and renal scar in early stages of disease is the superiority of MRI.

    Full Text Available ABSTRACT Chagas disease (CD is an important cause of cardiomyopathy and stroke in Brazil. Brain infarcts and atrophy seem to occur independently of cardiomyopathy severity and cognitive impairment is understudied. Objective: Compare the prevalence of brain magnetic resonance imaging abnormalities between patients with or without CD; determine if inflammatory biomarkers are increased in CD; and determine the efficacy of aspirin in reducing the rate of microembolization in these patients. Methods: 500 consecutive patients with heart failure will undergo a structured cognitive evaluation, biomarker collection and search for microembolic signals on transcranial Doppler. The first 90 patients are described, evaluated with cognitive tests and brain magnetic resonance imaging to measure N-acetyl aspartate (NAA, choline (Cho, myo-inositol (MI and creatine (Cr. Results: Mean age was 55±11 years, 51% female, 38 (42% with CD. Mean NAA/Cr ratio was lower in patients with CD as compared to other cardiomyopathies. Long-term memory and clock-drawing test were also significantly worse in CD patients. In the multivariable analysis correcting for ejection fraction, age, sex and educational level, reduced NAA/Cr (p=0.006 and cognitive dysfunction (long-term memory, p=0.023; clock-drawing test, p=0.015 remained associated with CD. Conclusion: In this preliminary sample, CD was associated with cognitive impairment and decreased NAA/Cr independently of cardiac function or educational level.

    The informationist programme at the Library of the National Institutes of Health (NIH) in Bethesda, MD, USA has grown to 14 informationists working with 40 clinical and basic science research teams. This case report, intended to contribute to the literature on informationist programmes, describes the NIH informationist programme, including implementation experiences, the informationists' training programme, their job responsibilities and programme outcomes. The NIH informationist programme was designed to enhance the library's service capacity. Over time, the steps for introducing the service to new groups were formalized to ensure support by leadership, the team being served and the library. Job responsibilities also evolved from traditional library roles to a wide range of knowledge management activities. The commitment by the informationist, the team and the library to continuous learning is critical to the programme's success. RESULTS / OUTCOMES: NIH scientists reported that informationists saved them time and contributed to teamwork with expert searching and point-of-need instruction. Process evaluation helped refine the programme. High-level, preliminary outcomes were identified from a survey of scientists receiving informationist services, along with key informant interviews. Process evaluation examined service implementation, informationists' training and service components. Anecdotal evidence has also indicated a favourable response to the programme.

    Factors predisposing to and associated with atherosclerosis may impact the onset and progression of Alzheimer disease (AD). The high prevalence of atherosclerosis and associated risk factors in American Indians makes them ideal subjects to test this association. We compared frequency of history of hypertension, myocardial infarction, stroke, diabetes, and high cholesterol in 34 American Indians with AD with 34 age-matched American Indian controls, and 34 age-matched whites with probable AD. We also measured waist size, height, and weight, and acquired blood for determination of plasma homocysteine and apolipoprotein E genotype. The 3 groups did not differ significantly in age or sex. History of hypertension and diabetes was significantly more common among American Indian AD patients than Indian controls or whites with AD. The 3 groups did not differ in history of stroke or myocardial infarction. Body mass index was significantly greater in both Indian groups than the white AD group. Plasma homocysteine levels were greater, but not significantly so, in the Indian AD than the Indian control group. Thus, there is preliminary evidence of a modest association between history of hypertension and diabetes and AD in a small sample of American Indians. This suggests that changes in lifestyle factors could influence the expression of AD in American Indians.

    Full Text Available The Daurian hedgehog ranges across northern Mongolia, southern Siberia, and northern China. However, few details of the species’ behavior, ecology, or distribution are known. We conducted a pilot study of the ranging behavior and diet of Daurian hedgehogs in Ikh Nart Nature Reserve, Mongolia. We captured and radio-tagged eight hedgehogs (six males/two females between June and September 2006. We tracked their movements until hibernation to estimate home range sizes and daytime nest characteristics. We also analyzed scats ( N = 38 to gain a preliminary understanding of the food habits of the species. During the study, we collected 237 hedgehog locations, including 91 night, 141 day, and fi ve hibernation sites. Hedgehogs were followed a mean of 53.43 ± 4.35 SE days from capture before entering hibernation. Mean home range size for seven hedgehogs was 422.72 ± 94.07 SE ha. Daytime nest sites had one, rarely two entrances, and usually occurred in rocky outcrops or at the base of shrubs. The most frequently occurring prey groups in scats included beetles (47%, cockroaches (28%, and grasshoppers (20%. Scats also included bird (3%, reptile (1%, and rodent (1% remains. Daurian hedgehogs in Ikh Nart were generally larger in size, occupied larger home ranges, and ate similar foods compared to Daurian hedgehogs in other regions. The presence of Daurian hedgehogs in Ikh Nart also represents a range extension for the species.

  2. Anut Grubyuk in the Voting Process: The Neglected Explanation of Javanese Voters (Preliminary Findings

    Full Text Available The “Javanese factor” is a strategic consideration in Indonesian electoral politics, as the Javanese are Indonesia’s most numerous inhabitants. However, seminal masterpieces such as those by Geertz (1960 and Gaffar (1992 apply only a limited and individual-based voting approach in their efforts to explain Javanese voting behavior. Recent qualitative case studies explore anut grubyuk (fitting in as a unique form of grouped rural Javanese voting behavior, rooted in the Javanese communal philosophy of life and hierarchical values. A study in four selected villages in Blitar and Trenggalek Regencies in East Java argues that individual Javanese voters adjust their voting decisions based on the major preference in their neighborhood, in keeping with the communal spirit of living in harmony as well as to avoid conflict and respect neighborly relationships. This article presents a preliminary assessment of anut grubyuk as group-oriented voting among the Javanese, a topic that has been relatively absent in academic discussion. Beyond cultural explanations, recent illiberal democratic practices have made anut grubyuk vulnerable to manipulation, since certain community leaders or brokers exploit Javanese communality in return for both individual and communal short-term benefits from candidates. Instead of helping with the growth of liberal democracy, anut grubyuk potentially supports patronage-driven democracy, in which small numbers of elites use patronage for influential control over electoral processes.

    The objectives of this study were to perform a preliminary investigation into the nature of electric shock-like experiences reported in association with the use of ecstasy tablets thought to contain methylenedioxymethamphetamines (MDMA). This included exploration of reports of electric shock-like experiences from the user's perspectives and identification of other variables that may be associated with their development. Furthermore we aimed to examine whether the well-recognised electric shock-like symptom, Lhermitte's sign (LS), is associated with ecstasy tablet use in some drug users. A single measure, cross-sectional survey was used incorporating mixed qualitative and quantitative methodology. A select group of ecstasy users (n = 35) recruited through a dance, music and lifestyle magazine completed a telephone interview. Lifetime prevalence of LS in the study population was 18% (n = 6). Development of LS was associated with use of more ecstasy tablets before a typical incident. This study indicates a relationship may exist between the use of ecstasy tablets and LS. The relationship may be dose dependent. The majority of the study population used other substances including alcohol when experiencing electrical shock sensations. LS may explain only a proportion of all electrical shock experiences among ecstasy users.

  5. Differential neuregulin 1 cleavage in the prefrontal cortex and hippocampus in schizophrenia and bipolar disorder: preliminary findings.

    Directory of Open Access Journals (Sweden)

    Ketan Marballi

    Full Text Available BACKGROUND: Neuregulin 1 (NRG1 is a key candidate susceptibility gene for both schizophrenia (SCZ and bipolar disorder (BPD. The function of the NRG1 transmembrane proteins is regulated by cleavage. Alteration of membrane bound-NRG1 cleavage has been previously shown to be associated with behavioral impairments in mouse models lacking expression of NRG1-cleavage enzymes such as BACE1 and gamma secretase. We sought to determine whether alterations in NRG1 cleavage and associated enzymes occur in patients with SCZ and BPD. METHODOLOGY/PRINCIPAL FINDINGS: Using human postmortem brain, we evaluated protein expression of NRG1 cleavage products and enzymes that cleave at the external (BACE1, ADAM17, ADAM19 and internal (PS1-gamma secretase sides of the cell membrane. We used three different cohorts (Controls, SCZ and BPD and two distinct brain regions: BA9-prefrontal cortex (Controls (n = 6, SCZ (n = 6 and BPD (n = 6 and hippocampus (Controls (n = 5, SCZ (n = 6 and BPD (n = 6. In BA9, the ratio of the NRG1 N-terminal fragment relative to full length was significantly upregulated in the SCZ cohort (Bonferroni test, p = 0.011. ADAM17 was negatively correlated with full length NRG1 levels in the SCZ cohort (r = -0.926, p = 0.008. In the hippocampus we found significantly lower levels of a soluble 50 kDa NRG1 fragment in the two affected groups compared the control cohort (Bonferroni test, p = 0.0018. We also examined the relationship of specific symptomatology criteria with measures of NRG1 cleavage using the Bipolar Inventory of Signs and Symptoms Scale (BISS and the Montgomery Åsberg Depression Rating Scale (MADRS. Our results showed a positive correlation between ADAM19 and psychosis (r = 0.595 p = 0.019; PS1 and mania (r = 0.535, p = 0.040; PS1 and depression (r = 0.567, p = 0.027 in BA9, and BACE1 with anxiety (r = 0.608, p = 0.03 in the hippocampus. CONCLUSION/SIGNIFICANCE: Our preliminary findings suggest region-specific alterations in NRG1

    The Swaziland Diarrheal Disease Control campaign, a collaboration of the Ministry of Health of Swaziland, the Combatting Childhood Communicable Diseases project, and the Agency for International Development (AID) Communication for Child Survival (HEALTHCOM) Project, was based on earlier work in Swaziland as well as the previous health communications programs in Honduras and Gambia. As in the other programs, it relied on a combination of mass media and face-to-face channels in an effort to change practices related to the treatment of diarrheal disease. The preparatory phase of the campaign was initiated in April 1984; the formal campaign ran from September 1984 through March 1985. The campaign involved 3 components: radio programs to be developed in an intensive radio workshop and broadcast on current development programs carried on the national radio system; printed materials including a flyer with mixing instructions and posters for display at health clinics and elsewhere; and workshops to train the health staff, other extension personnel, and local volunteers in treatment of diarrheal diseases, including use of oral rehydration therapy (ORT) for dehydration. The campaign focused on a few objectives, specifically: acceptance of a home-mixed water/sugar/salt (WSS) solution as a treatment for diarrheal dehydration; continued feeding during episodes of diarrhea; and feeding with special foods after diarrheal episodes. The campaign particularly emphasized the introduction of a new formula for mixing the solution -- 1 liter of water, 8 soda bottlecapfuls of sugar, and 1/2 capful of salt. The evaluation reveals preliminary results suggesting that the campaign achieved noteworthy success, particularly in rates of adoption of recommended practices. Data sources included before and after campaign surveys, each with 450 rural mothers chosen through national random sampling procedures, and a diarrheal disease registry kept by 20 clinics which listed more than 10,000 children

    Giant weathering pits formed in outcrops of the lower Entrada Sandstone slickrock of Jurassic age are present in two areas in the Glen Canyon region of arid southeastern Utah. The pits are far larger than any previously described in the geologic literature. The pits near Cookie Jar Butte are commonly cylindrical, typically have low width-to-depth ratios (1.5--3.6), and have a depth of closure of as much as 18 m. There are no obvious lithologic or structural controls that determine their shape or location. Many of the pits at Rock Creek Bay are elongate; several of them have long axes in excess of 53 m, and the longest one is 74 m. Many of the pit walls are breached at the top, and the depth of closure is generally less than 6 m. The shapes of these pits are influenced by point orientation and pit coalescence. Thin-section analyses of near-surface sandstone cores taken near Cookie Jar Butte from pit walls, floors, and rims reveal no significant diagenetic alteration of the fine-grained to very fine frained quartzose sandstone (quartz arenite). Quartz grains appear fresh, and feldspar grains are only slightly weathered. The cement between the grains is mostly CaCO[sub 3]. In several of the pits in both areas sandy sediment veneers the bedrock floor. This sediment is similar in character to the adjacent sandstone and is probably locally derived. Possible origins of the giant pits include various physical, chemical, and biological weathering processes that initiate pit development, followed by excavation by plunge-pool action, wind deflation, dissolution, and piping. Preliminary field and laboratory data do not clearly identify and single process of group of processes that account for pit development.

    This investigation contributes for bridging the gap in Earth observation between field and airborne measurements. We will reduce the risk of operating science grade instruments from Unmanned Aerial Systems (UAS), by developing robust methods to make well-characterized spectral measurements for integration, calibration and validation with NASAs science quality satellite and airborne data. Because of the potential for rapid deployment, spatially explicit data from UASs can be acquired irrespective of many of the cost, scheduling and logistic limitations to satellite or piloted aircraft missions. Provided that the measurements are suitably calibrated and well characterized, this opens up opportunities for calibration/validation activities not currently available. There is considerable interest in UASs from the agricultural and forestry industries but there is a need to identify a workflow that yields calibrated comparisons through space and time. The goal of our effort is to ensure that optical high spectral resolution measurements from UAV's are collected and processed in a fashion that allows ready integration with or comparison to NASA satellite and airborne data and derived products. We target the consistent retrieval of calibrated surface reflectance, as well as biological parameters including nutrient and chlorophyll content, chlorophyll fluorescence and photosynthetic capacity. We will test our technology and protocols first using spatially-resolved discrete point measurements characterizing canopy VNIR reflectance and solar-induced fluorescence, followed by imaging spectroscopy. A Rapid Data Assimilation and delivery system will be developed, based on SensorWeb Intelligent Payload Module for high speed onboard processing. The deployment of UAS sensors at sites such as flux towers will facilitate measrurement validation and parameter retrieval, than is possible by foot, from sensors fixed to a tower, or irregular aircraft missions. We will report preliminary

    Conclusions: Divergent patterns between current MJ use and elements of cortical architecture were associated with early MJ use onset. Considering brain development in early adolescence, findings are consistent with disruptions in pruning. However, divergence with continued use for many years thereafter suggests altered trajectories of brain maturation during late adolescence and beyond.

    We report our experience with the arthroscopic treatment of 23 cases of scaphoid nonunion. We explain the surgical technique and describe the different steps needed to achieve bone union. We report our initial clinical and radiological results. This was a prospective non-randomized study. Inclusion criteria were a scaphoid nonunion without radiocarpal arthritis, without any time limit and without any selection as to nonunion location. Before the operation, patients underwent an X-Ray and CT scan or MRI. Schernberg's classification was used to evaluate the location of the nonunion. Internal fixation was performed with a screw or K-wires. Bone grafts were taken from the dorsal side of the distal radius using a T-Lok™ bone marrow biopsy needle (Argon Medical Devices, Plano, TX, USA). A CT scan was performed 3 months after the operation to determine whether union was achieved. Pain, strength and range of motion were evaluated before and after the operation. The patients' smoking habits were also documented. The average follow-up was 17.3 months (4-41). There were 20 men and 3 women with an average age of 26 years (17-63). The average duration of nonunion before the operation was 17 months (6-60). Based on Schernberg's classification, there was one type I, 12 type II and 10 type III nonunions. Wrist strength increased from 32 to 41kg. Union was obtained in all patients after an average of 4 months (3-12). Numerous treatments have been described for treating scaphoid nonunion: Matti-Russe, Fisk-Fernadez bone graft, vascularized bone graft, bone substitutes, etc. The success rate varies depending on the technique and study design. We have described an arthroscopic technique for treating scaphoid nonunion with very promising preliminary results. Arthroscopic debridement is needed to ensure good quality bone at the graft site, while preserving extrinsic vascularization. Traction is used during the operation to restore the scaphoid height, once debridement has been

    Full Text Available The implementation of environmental management system (EMS by public sector agencies is in line with the Malaysian Government Transformation Programme (GTP and the New Public Management doctrine. Local authority is chosen as a sample because of its important role in advancing towards sustainable development. This study aims to examine impediments to the ISO 14001 implementation by Malaysian local authorities using the institutional theory as the underlying framework. The survey instrument was developed and distributed via mail to all 146 local authorities in Malaysia. Finding revealed that the impediments to the EMS implementation were explained by lack of coercive, normative and mimetic isomorphism under the institutional theory. It is expected that the survey findings would fill in the gaps in the literature in better understanding the lack of implementation of IS00 14001 particularly in the emerging economy.

    Full Text Available Introduction. The aim of this article is to discuss the relationship between affective states experienced by athletes and the outcome of their performance. The article presents the findings of a pilot study which made it possible to determine the relationship between the emotional states, mood, and level of stress of a group of pentathletes and the outcomes they achieved in a sports competition. Material and methods. The study involved 12 senior modern pentathletes, including 7 male and 5 female athletes. The following standard psychology questionnaires were used in the study: the 10-item Perceived Stress Scale (PSS-10, the Positive and Negative Affect Schedule (PANAS, and the Profile of Mood State (POMS. Performance was assessed based on the number of points achieved by the pentathletes in particular events in the pentathlon, which are held according to the rules set by the International Modern Pentathlon Union (UIPM. Results. The findings of the study confirmed that there was a correlation between the athletes’ mood and emotions and the outcome of their performance. The level of stress strongly negatively correlated with both the outcome they expected to achieve and the one they actually achieved for the combined event (running and shooting. For this event a relationship was also found between the athletes’ affective states and their outcomes: in running and shooting there was a positive and statistically significant correlation between the level of positive emotions and anger and the results achieved. However, friendliness, one of the other affective state variables that were measured, correlated negatively with the outcomes of the athletes’ performance. Conclusions. In the group of pentathletes who participated in the study, a high level of anger was associated with better outcomes, and a high level of friendliness had an adverse effect on the results achieved. The findings of the current study confirm that there is a relationship

    This article presents the results of a randomized trial in South Africa of an adapted evidence-based Woman-Focused intervention on condom use with primary sex partners. The preliminary findings show that regardless of HIV status, condom negotiation was significantly associated with condom use at the 3- and 6-month follow-ups. By intervention group, significant intervention effects were found at 6-month follow-up for HIV-positive and HIV-unknown status women in the Woman-Focused intervention who were more likely than women in the Standard intervention to report condom use with a primary male partner. Among HIV-positive women, those in the Woman-Focused group and those with greater sexual control were more likely to report condom use at the 6-month follow-up. The findings indicate that gender-based interventions for women may result in increased condom negotiation skills.

    Directory of Open Access Journals (Sweden)

    Flavia Mattioli

    Full Text Available Previous studies reported that Multiple Sclerosis (MS patients treated with natalizumab for one or two years exhibit a significant reduction in relapse rate and in cognitive impairment, but the long term effects on cognitive performance are unknown. This study aimed to evaluate the effects of natalizumab on cognitive impairment in a cohort of 24 consecutive patients with relapsing remitting MS treated for 3 years. The neuropsychological tests, as well as relapse number and EDSS, were assessed at baseline and yearly for three years. The impact on cortical atrophy was also considered in a subgroup of them, and are thus to be considered as preliminary. Results showed a significant reduction in the number of impaired neuropsychological tests after three years, a significant decrease in annualized relapse rate at each time points compared to baseline and a stable EDSS. In the neuropsychological assessment, a significant improvement in memory, attention and executive function test scores was detected. Preliminary MRI data show that, while GM volume did not change at 3 years, a significantly greater parahippocampal and prefrontal gray matter density was noticed, the former correlating with neuropsychological improvement in a memory test. This study showed that therapy with Natalizumab is helpful in improving cognitive performance, and is likely to have a protective role on grey matter, over a three years follow-up.

    In the context of successful antiretroviral therapy (ART) for the management of HIV infection, the harmful effects of stress remain a significant threat. Stress may increase viral replication, suppress immune response, and impede adherence to ART. Stressful living conditions of poverty, facing a chronic life-threatening illness and stigma all exacerbate chronic stress in HIV-affected populations. Stress-reduction interventions are urgently needed for the comprehensive care of people living with HIV. Mindfulness-based stress reduction (MBSR) is one approach that has shown promise as an intervention for patients facing other medical conditions for reducing disease progression, psychological distress and maladaptive behaviours. In this systematic review, we identified 11 studies that have examined MBSR as an intervention for HIV-positive populations. Of the studies, six were randomised designs, one was a quasi-experimental design, and the remaining four were pre- and post-test designs. The preliminary outcomes support MBSR to decrease emotional distress with mixed evidence for impact on disease progression. Effect sizes were generally small to moderate in magnitude. The early findings from this emerging literature must be considered preliminary and support moving forward with more rigorous controlled trials, evaluated with objective assessments in longer-term follow-ups to determine the efficacy of MBSR for people living with HIV.

    The aim of this study was to compare ultrasonographic features in patients with lymphocytic thyroiditis (LT) and papillary thyroid carcinoma (PTC) having suspicious thyroid nodule(s) in a background of heterogeneous parenchyma and to determine the clinical and radiological predictors of malignancy. We reviewed the cases of 100 patients who underwent ultrasonography between April 2011 and October 2012, and showed suspicious thyroid nodule(s) in a background of heterogeneous parenchyma. Eight patients who did not undergo ultrasonography-guided fineneedle aspiration cytology (FNAC) and 34 cases of follow-up ultrasonography after initial FNAC were excluded. We compared the benign and malignant nodules in terms of their clinical and radiological factors. For the 58 nodules including 31 LTs (53.4%) and 27 PTCs (46.6%), the mean tumor sizes of the two groups were 0.96 cm for LT and 0.97 cm for PTC. A univariate analysis revealed that PTCs were more frequent in patients younger than 45 years and having microcalcifications than was LT. An independent predictor of PTC after adjustment was an age of <45 years. LT mimics malignancy in a background of heterogeneous parenchyma on ultrasonography. A young age of <45 years is the most important predictor of malignancy in this condition.

    Music evoked autobiographical memories (MEAMs) have been characterised in the healthy population, but not, to date, in patients with acquired brain injury (ABI). Our aim was to investigate music compared with verbal evoked autobiographical memories. Five patients with severe ABI and matched controls completed the experimental music (MEAM) task (a written questionnaire) while listening to 50 "Number 1 Songs of the Year" (from 1960 to 2010). Patients also completed the Autobiographical Memory Interview (AMI) and a standard neuropsychological assessment. With the exception of Case 5, who reported no MEAMs and no autobiographical incidents on the AMI and who also had impaired pitch perception, the range of frequency and type of MEAMs in patients was broadly in keeping with their matched controls. The relative preservation of MEAMs in four cases was particularly noteworthy given their impaired verbal and/or visual anterograde memory, and in three cases, autobiographical memory impairment. The majority of MEAMs in both cases and matched controls were of a person/people or a period of life. In three patients music was more efficient at evoking autobiographical memories than the AMI verbal prompts. This is the first study of MEAMs after ABI. The findings suggest that music is an effective stimulus for eliciting autobiographical memories, and may be beneficial in the rehabilitation of autobiographical amnesia, but only in patients without a fundamental deficit in autobiographical recall memory and intact pitch perception.

    Bone involvement in Langerhans' cell histiocytosis (LCH) is common. Both bone scintigraphy and plain films are used to identify osseous lesions, but lack specificity for disease activity and response to therapy. FDG-PET is a sensitive technique for identifying bone lesions when histiocytes are present. To describe the potential of coincidence FDG-PET (cFDG-PET) for identification of active bone lesions in LCH and to determine whether it can provide more specific information regarding lesional response to therapy than bone scintigraphy or radiography. The clinical data and imaging findings of three patients with osseous lesions of LCH were retrospectively reviewed. cFDG-PET identified all active LCH osseous lesions in these patients, differentiated active from healed lesions, and demonstrated normalization of uptake in a treated lesion earlier than bone scintigraphy and radiography. cFDG-PET appears to have greater specificity than bone scintigraphy and radiography for the identification of active osseous lesions in LCH. It also may predict response to treatment earlier than conventional techniques. Its use in the evaluation of LCH warrants further study. (orig.)

    Telemedicine was used as a substitute for the telephone (usual care) for some acute care consultations from nurseries at four peripheral hospitals in Queensland. Over a 12-month study period, there were 19 cases of neonatal teleconsultation. Five (26%) cases of avoided infant transport were confirmed by independent assessment, four of which were avoided helicopter retrievals. We conducted two analyses. In the first, the actual costs of providing telemedicine at the study sites were compared with the actual savings associated with confirmed avoided infant transport and nursery costs. There was a net saving to the health system of 54,400 Australian Dollars (AUD) associated with the use of telemedicine over the 12-month period. In the second analysis, we estimated the potential savings that might have been achieved if telemedicine had been used for all retrieval consultations from the study sites. The total projected costs were AUD 64,969 while the projected savings were AUD 271,042, i.e. a projected net saving to the health system of AUD 206,073 through the use of telemedicine. A sensitivity analysis suggested that the threshold proportion of retrievals needed to generate telemedicine-related savings under the study conditions was 5%. The findings suggest that from the health-service perspective, the use of telemedicine for acute care neonatal consultation has substantial economic benefits.

    Although video feedback (VF) is shown to improve appraisals of social performance in socially anxious individuals, its impact on state anxiety during a social situation is mixed. The current study investigated the effect of combined video feedback and audience feedback (AF) on self-perceptions of performance and bodily sensations as well as state anxiety pertaining to a speech task. Forty-one socially anxious students were randomly allocated to combined video feedback with audience feedback (VF + AF), video feedback only (VF), audience feedback only (AF), or a control condition. Following a 3-min speech, participants in the VF + AF, VF, and AF conditions watched the videotape of their speech with cognitive preparation in the presence of three confederates who served as audience, and/or received feedback from the confederates, while the control group watched their videotaped speech without cognitive preparation. Both VF + AF and AF conditions improved distorted appraisal of performance and bodily sensations as well as state anxiety. The clinical implications of these findings are discussed.

    The purpose of this study was to investigate whether variations in disfluencies of young children who do (CWS) and do not stutter (CWNS) significantly change their talker group classification or diagnosis from stutterer to nonstutterer, and vice versa. Participants consisted of 17 3- to 5-year-old CWS and 9 3- to 5-year-old CWNS, with no statistically significant between-group difference in chronological age (CWS: M = 45.53 months, SD = 8.32; CWNS: M = 47.67 months, SD = 6.69). All participants had speech, language, and hearing development within normal limits, with the exception of stuttering for CWS. Both talker groups participated in a series of speaking samples that varied by: (a) conversational partner [parent and clinician], (b) location [home and clinic], and (c) context [conversation and narrative]. The primary dependent measures for this study were the number of stuttering-like disfluencies (SLD) per total number of spoken words [%SLD] and the ratio of SLD to total disfluencies (TD) [SLD/TD]. Results indicated that significant variability of stuttering did not exist as a result of conversational partner or location. Changes in context, however, did impact the CWS, who demonstrated higher SLD/TD in the conversation sample versus a narrative sample. Consistent with hypotheses, CWS and CWNS were accurately identified as stutterers and nonstutterers, respectively, regardless of changes to conversational partner, location or context for the overall participant sample. Present findings were taken to suggest that during assessment, variations in stuttering frequency resulting from changes in conversational partner, location or context do not significantly influence the diagnosis of stuttering, especially for children not on the talker group classification borderline between CWS and CWNS.

    5-androstenediol (5-AED) has been advanced as a possible countermeasure for treating the haematological component of acute radiation syndrome (ARS). It has been used in animal models to stimulate both innate and adaptive immunity and treat infection and radiation-induced immune suppression. We here report on the safety, tolerability and haematologic activity of 5-AED in four double-blinded, randomized, placebo-controlled studies on healthy adults including elderly subjects. A 5-AED injectable suspension formulation (NEUMUNE) or placebo was administered intramuscularly as either a single injection, or once daily for five consecutive days at doses of 50, 100, 200 or 400 mg. Subjects (n = 129) were randomized to receive NEUMUNE (n = 95) or the placebo (n = 34). NEUMUNE was generally well-tolerated; the most frequent adverse events were local injection site reactions (n = 104, 81%) that were transient, dose-volume dependent, mild to moderate in severity, and that resolved over the course of the study. Blood chemistries revealed a transient increase (up to 28%) in creatine phosphokinase and C-reactive protein levels consistent with intramuscular injection and injection site irritation. The blood concentration profile of 5-AED is consistent with a depot formulation that increases in disproportionate increments following each dose. NEUMUNE significantly increased circulating neutrophils (p < 0.001) and platelets (p < 0.001) in the peripheral blood of adult and elderly subjects. A dose-response relationship was identified. Findings suggest that parenteral administration of 5-AED in aqueous suspension may be a safe and effective means to stimulate innate immunity and alleviate neutropenia and thrombocytopenia associated with ARS.

    Objective: The differential diagnosis between atypical parkinsonism and Parkinson’s disease is difficult, especially in the early stage. Severe postural instability, falls, and complex gait impairments are usually confined to the later stage of Parkinson’s disease, while atypical parkinsonism patients may present a severe postural instability with consequent falls in the earlier stages. Methods: We retrospectively studied 20 subjects with parkinsonism using clinical and baropodometric tools to give quantitative and objective data on the postural, balance, and gait disturbances. Results: The statistical analysis between atypical parkinsonism and Parkinson’s disease patients showed a significant difference in the frequency of long lead time parameter, foot area, foot load and speed, and, in particular, atypical parkinsonism patients presented a prevalent long lead time impairment (8/8 patients) when compared with Parkinson’s disease patients. Discussion: Beside significant differences in the clinical features between the Parkinson’s disease and atypical parkinsonism, our study showed that baropodometric investigation may a valuable tool for the definition of postural and motor extrapyramidal abnormalities, permitting an earlier differentiation between atypical parkinsonism and Parkinson’s disease.

    Full Text Available Abstract Background Biological control methods are once again being given much research focus for malaria vector control. This is largely due to the emerging threat of strong resistance to pesticides. Larvivorous fish have been used for over 100 years in mosquito control and many species have proved effective. In the western Kenyan highlands the larvivorous fish Oreochromis niloticus L. (Perciformes: Cichlidae (formerly Tilapia nilotica is commonly farmed and eaten but has not been previously tested in the field for malaria mosquito control. Methods This fish was introduced into abandoned fishponds at an altitude of 1,880 m and the effect measured over six months on the numbers of mosquito immatures. For comparison an untreated control pond was used. During this time, all ponds were regularly cleared of emergent vegetation and fish re-stocking was not needed. Significant autocorrelation was removed from the time series data, and t-tests were used to investigate within a pond and within a mosquito type any differences before and after the introduction of O. niloticus. Mulla's formula was also used on the raw data to calculate the percentage reduction of the mosquito larvae. Results After O. niloticus introduction, mosquito densities immediately dropped in the treated ponds but increased in the control pond. This increase was apparently due to climatic factors. Mulla's formula was applied which corrects for that natural tendency to increase. The results showed that after 15 weeks the fish caused a more than 94% reduction in both Anopheles gambiae s.l. and Anopheles funestus (Diptera: Culicidae in the treated ponds, and more than 75% reduction in culicine mosquitoes. There was a highly significantly reduction in A. gambiae s.l. numbers when compared to pre-treatment levels. Conclusion This study reports the first field trial data on O. niloticus for malaria mosquito control and shows that this species, already a popular food fish in western Kenya

    This functional magnetic resonance imaging study was designed to observe how physiological brain states can alter food preferences. A primary goal was to observe food-sensitive regions and moreover examine whether 5-HTP intake would activate areas which have been associated with appetite suppression, anorexia, satiety, and weight loss. Fourteen healthy male and female participants took part in the study, of which half of them received the supplement 5-HTP and the rest vitamin C (control) on an empty stomach. During the scanning session, they passively observed food (high calories, proteins, carbohydrates) and nonfood movie stimuli. Within the 5-HTP group, a comparison of food and nonfood stimuli showed significant responses that included the limbic system, the basal ganglia, and the prefrontal, temporal, and parietal cortices. For the vitamin C group, activity was mainly located in temporal and occipital regions. Compared to the vitamin C group, the 5-HTP group in response to food showed increased activation on the VMPFC, the DLPFC, limbic, and temporal regions. For the 5-HTP group, activity in response to food high in protein content compared to food high in calories and carbohydrates was located in the limbic system and the right caudomedial OFC, whereas for the vitamin C group, activity was mainly located at the inferior parietal lobes, the anterior cingulate gyri, and the left ventrolateral OFC. Greater responses to carbohydrates and high calorie stimuli in the vitamin C group were located at the right temporal gyrus, the occipital gyrus, the right VLPFC, whereas for the 5-HTP group, activity was observed at the left VMPFC, the parahippocampal gyrus bilaterally, the occipital lobe, and middle temporal gyri. In line with the hypotheses, 5-HTP triggered cortical responses associated with healthy body weight as well as cerebral preferences for protein-rich stimuli. The brain's activity is altered by macronutrients rich or deprived in the body. By reading the

    This study examined bereaved children's HPA-axis functioning (cortisol awakening response; CAR) in relation to psychological distress, coping, and surviving parents' grief reactions. Participants included 38 children (20 girls) with recent parental loss (previous 6 months) and 28 of their surviving caregivers (23 women) who were assessed using self-report instruments and in-person, semistructured interviews. Interviews involved discussions about the child's thoughts and feelings related to the loss. Participants provided 3 saliva samples at home (awakening, 30 minutes later, and evening) over 3 successive days, beginning on the day following the interview. Results show a significant relation between dampening of the child's Day 1 CAR and more symptoms of anxiety (r = -.45), depression (r = -.40), posttraumatic stress (r = -.45), and maladaptive grief (r = -.43), as well as higher levels of avoidant coping (r = -.53). Higher levels of parental maladaptive grief were also associated (r = -.47) with a dampening of the child's Day 1 CAR. Our results raise the possibility that blunted CAR may be a result of accumulating allostatic load and/or a result of emotionally challenging events (discussions regarding the deceased) and their subsequent processing (or lack thereof) within the family, which may be particularly stressful for those bereaved children experiencing high levels of psychological distress, avoidant coping, and parental maladaptive grief.

    Full Text Available The study describes the development and validation of two scales which can be used in evaluating schizoid and antisocial personality disorders. Both scales were developed relying on descriptions from DSM 5 and ICD 10. For validation, the scales have been tested on 125 subjects, together with two well-known psychometric instruments, DA12profile Personality Inventory, and SCL-90. Internal consistency is calculated using Cronbach's alpha coefficient. Schizoid Scale contains 20 items and shows a good internal consistency (Cronbach's α = .77 and Antisocial Scale contains 22 items and has excellent internal consistency (Cronbach's α = .91. The correlations between the scores of the two scales and the scores of DA12profile Personality Inventory and SCL-90 are statistically significant. The factorial analysis reveals that the two scales and DA12profile Personality Inventory sub-scales are clustered in four factors, explaining 68.31 % of the variance. Based on these results, we discussed the importance the scales have for psychological research and for psycho-diagnostic, their limitations and our future directions of research.

    The purpose of this study was to examine the feasibility of an intervention that included heart rate variability (HRV) biofeedback and walking with pulse oximetry feedback to improve functioning and quality of life for patients with chronic obstructive pulmonary disease (COPD). Twenty patients with COPD participated in 5 weekly sessions of HRV biofeedback and 4 weekly sessions of walking practice with oximetry feedback, with instructions for daily home practice. Primary outcomes measures were the distance walked in 6 min (6MWD) and overall quality of life, as measured by the St. George's Respiratory Questionnaire (SGRQ). Secondary outcomes included measures of self-efficacy, self-reported disability, anxiety, depression, dyspnea before and after the 6MWD, and HRV at the frequency of respiration during spontaneous and paced breathing. After 10 weeks of training, participants showed statistically and clinically significant improvements in 6MWD and quality of life. Significant changes were also seen in self-efficacy, disability, dyspnea before and after the 6MWD, and HRV amplitude during spontaneous breathing. We conclude that our intervention is feasible for patients with COPD and that further research using a randomized controlled design is warranted.

    2015-01-01

    This study analyzed students' written reflections following their initial exposure to interprofessional teamwork in case-based problem-solving. A three-hour seminar featuring three sequenced scenarios was developed and offered 12-times over two semesters. A total of 305 students from a variety of healthcare programs worked together with standardized patients in an on-campus laboratory simulating hospital ward and rehabilitation settings. A thematic analysis of students' reflections showed that they valued the shared learning and realistic case study. However, they felt the experience would be strengthened by working in smaller, more representative teams that included students from medicine, psychology, and social work to enable more effective communication and comprehensive case discussion. While useful for future planning, the identified themes did not enable a comparative statistical analysis of what students found helpful and difficult and a re-coding of students' responses now is underway. Implications for measuring the effectiveness of future interprofessional case-based learning center on addressing the identified weaknesses, and establishing a research design that enables a comparison of pre- and post-seminar data, and the effectiveness of the IPE experience compared to profession-specific experiences.

    A recent Supreme Court decision--Atkins v. Virginia, 536 U.S. 304 (2002)--prohibiting the execution of mentally retarded (MR) defendants may have raised the attractiveness of feigning this condition in the criminal justice system. Unfortunately, very few published studies have addressed the detection of feigned MR. The present report compared results from tests of intelligence, psychiatric feigning, and neurocognitive faking in a group of 26 mild MR participants (MR) and 25 demographically matched community volunteers asked to feign MR (CVM). Results showed that the CVM suppressed their IQ scores to approximate closely the level of MR participants. WAIS-III and psychiatric malingering measures were relatively ineffective at discriminating feigned from genuine MR. Although neurocognitive malingering tests were more accurate, their reduced specificity in MR participants was of potential concern. Revised cutting scores, set to maintain a Specificity rate of about .95 in MR clients, were identified, although they require cross-validation. Overall, these results suggest that new cutting scores will likely need to be validated to detect feigned MR using current malingering instruments.

  18. Preliminary findings of similarities and differences in the signed and spoken language of children with autism.

    2014-11-01

    Approximately 30% of hearing children with autism spectrum disorder (ASD) do not acquire expressive language, and those who do often show impairments related to their social deficits, using language instrumentally rather than socially, with a poor understanding of pragmatics and a tendency toward repetitive content. Linguistic abnormalities can be clinically useful as diagnostic markers of ASD and as targets for intervention. Studies have begun to document how ASD manifests in children who are deaf for whom signed languages are the primary means of communication. Though the underlying disorder is presumed to be the same in children who are deaf and children who hear, the structures of signed and spoken languages differ in key ways. This article describes similarities and differences between the signed and spoken language acquisition of children on the spectrum. Similarities include echolalia, pronoun avoidance, neologisms, and the existence of minimally verbal children. Possible areas of divergence include pronoun reversal, palm reversal, and facial grammar. Thieme Medical Publishers 333 Seventh Avenue, New York, NY 10001, USA.

    Impairments in social cognition are critical predictors of social functioning in patients with schizophrenia. Emotion processing (EP) and theory of mind (ToM) are hypothesized to influence real-world behavior more directly than basic cognition and represent important targets of intervention. The use of video scenes depicting human interactions could constitute an appropriate tool to enhance understanding of the characters' behavior and stimulate inferences on mental states. The aim of our pilot study was to evaluate longitudinally, with a controlled trial, the feasibility and the efficacy of a single-paradigm emotion recognition and ToM training designed for outpatients affected by schizophrenia, with the goal to create an ecological treatment, overcoming artificial laboratory biases, by the use of specific videotaped material. Fifty-two outpatients were randomly assigned to an EP and ToM video-based training (n=27) or to a standard social cognitive rehabilitation treatment (n=24). They were assessed before and after 12 weeks of intervention and compared to a time-matched control group (n=24). Our results show a statistically significant improvement in ToM abilities, confirming the hypothesis of the enhancing potential of social cognitive interventions, but no changes with respect to EP; despite the need for a deeper examination, these data support further development of this treatment approach.

    2016-06-01

    Full Text Available Ethical principles constitute a crucial area of debate and discussion in the global conversation around transitions to sustainability, and of particular relevance to the contribution of businesses and other organizations. Scholars in business ethics have recently identified several challenges in this area, such as problems of measurement, rigor, and meaningfulness to practitioners; corporate social responsibility; and institutionalization of ethics in businesses. In this paper, the impacts of a pragmatic values-based evaluation approach originally developed in another field—education for sustainable development—are shown to strongly contribute to many of these challenges. Impacts found across eight organizations include (i deep values conceptualization; (ii increased esteem (iii building capacity for assessment of values-based achievements; (iv values mainstreaming; and (v effective external values communications. It seems that the in-situ development and use of values-based indicators helped to conceptualize locally shared values that underpin decisions, thus embedding the application of (local ethics. Although this study is exploratory, it is clear that the values-based approach shows promise for meeting key challenges in business ethics and wider sustainability, and for new directions for future cross-disciplinary research.

    To assess the potential value of magnetic resonance (MR) imaging in evaluating pancreatic fibrosis and predicting the development of postoperative pancreatic fistula. This retrospective study had institutional review board approval, and the requirement for informed consent was waived. MR images obtained in 29 consecutive patients (15 men, 14 women; mean age, 64.9 years; age range, 21-80 years) who underwent pancreatectomy were evaluated. The pancreas-to-muscle signal intensity (SI) ratio on unenhanced T1- and T2-weighted, dynamic contrast material-enhanced, and diffusion-weighted images and the apparent diffusion coefficient (ADC) of the pancreas were measured. MR imaging parameters were correlated with the degrees of pancreatic fibrosis and expression of activated pancreatic stellate cells (PSCs) by using univariate and multivariate regression analyses and receiver operating characteristic curve analysis. The relationships between the development of postoperative pancreatic fistula and the MR imaging measurements were examined by using logistic regression analysis and the Mann-Whitney U test. Multiple regression analysis showed that pancreas-to-muscle SI ratios on T1-weighted images and ADC values were independently associated with pancreatic fibrosis (r(2) = 0.66, P fistula (1.6 ± 0.2) than for those without (1.2 ± 0.2), and the odds ratio for postoperative pancreatic fistula was 21.3 in patients with an SI ratio of 1.41 and higher. The pancreas-to-muscle SI ratio on T1-weighted MR images of the pancreas may be a potential biomarker for assessment of pancreatic fibrosis and prediction of postoperative pancreatic fistula.

    Health-related quality of life (HRQoL) is often substantially reduced among individuals who have undergone hematopoietic stem cell transplantation (HSCT), and incidences of depression, fatigue, and anxiety are elevated. We examined effects of a mindfulness-based intervention (MBI) compared to psycho-oncological telephone consultation upon HRQoL, depression, anxiety, and fatigue among HSCT survivors. Sixty-two medically stable patients participated in the study; they had completed HSCT ≥6 months previously. Thirty-two were randomly assigned to intervention arms, and 30 were offered their treatment preference. MBI consisted of a structured 8-week program of mindfulness training. Assessments were made at baseline, post-intervention and 3 months follow-up. Primary outcome was HRQoL. Depression, fatigue, anxiety, and personal goal attainment were secondary measures. Non-completion of interventions was low in both groups (9 %, MBI; 7 % control). Employing intention-to-treat analysis, MBI, compared with comparison procedure, improved HRQoL and reduced depression and anxiety at post-intervention (p's benefits were modest. These findings demonstrate broad feasibility and acceptance of, as well as satisfaction and adherence with, a program of mindfulness training for HSCT survivors; findings also suggest improved HRQoL and well-being as a consequence of MBI. Nevertheless, this is a preliminary study; a larger trial with more prolonged intervention phase is warranted.

    Full Text Available Background: In 2011, the Veterans Health Administration (VHA consulted with the Project ECHO (Extension for Community Healthcare Outcomes team at the University of New Mexico, Albuquerque, to reproduce their successful model within the VHA. Methods: The VHA launched SCAN-ECHO (Specialty Care Access Network-Extension for Community Healthcare Outcomes, a multisite videoconferencing system to conduct live clinical consultations between specialists at a VHA Medical Center (hospital and primary care providers stationed at satellite VHA CBOCs (Community-Based Outpatient Clinic. Results: Analysis of the first three years rendered a mean attendee satisfaction of 89.53% and a consultation satisfaction score of 88.10%. About half of the SCAN-ECHO consultations resulted in patients receiving their treatment from their local primary care providers; the remaining half were referred to the VHA Medical Center when the treatment involved equipment or services not available at the CBOCs (e.g., MRI, surgery. Conclusion: This paper details the setup, operation logistics and preliminary findings, suggesting that SCAN-ECHO is a viable model for providing quality specialty clinical consultation service, prompter access to care, reduced commutes and continuing education. Additionally, the use of a secured Internet-based videoconferencing system that supports connectivity to multiple (mobile devices could expand the utilization of this service.

    Full Text Available Student evaluation of teaching (SET is important to faculty because SET ratings help faculty improve performance and are often used as the basis for evaluations of teaching effectiveness in administrative decisions (e.g., tenure. Researchers have conducted over 2,000 studies on SET during the past 70 years. However, despite the explosive growth in online education during the past decade, researchers have largely neglected the use of SET to evaluate teaching effectiveness in online courses. This exploratory study analyzed the actual SET data collected during a single semester at a large mid-western college that offers over 250 online/Web-based classes. The data included five dependent and eighteen independent measures of teaching effectiveness. The results indicate that average SET ratings in online classes are significantly lower than the average ratings in on-campus classes across all five dependent measures. This finding offers preliminary empirical support for anecdotal evidence cited by earlier authors in this field. Furthermore, regression analysis of the full model for each dependent variable indicated that the independent variables explained a significant portion of the variance in SET ratings. Examination of the standardized beta coefficients revealed that the strength and significance of the independent variables varied across the five dependent measures. Findings also indicate that organization of the course materials had a strong impact on all five measures of overall teaching effectiveness. Other variables including clarity of the instructor’s writing, timeliness in providing feedback, and interest in whether students learned were also significant factors in models that measured instructor effectiveness (as opposed to models that measured quality of course content. The paper concludes with a discussion of the implications of this study for administrators, faculty, and researchers.

    Recent observations that personality traits are related to later-life health and wellbeing have inspired considerable interest in exploring the mechanisms involved. Other factors, such as cognitive ability and education, also show longitudinal influences on health and wellbeing, but it is not yet clear how all these early-life factors together contribute to later-life health and wellbeing. In this preliminary study, we assessed hypothesised relations among these variables across the life course, using structural equation modelling in a sample assessed on dependability (a personality trait related to conscientiousness) in childhood, cognitive ability and social class in childhood and older age, education, and health and subjective wellbeing in older age. Our models indicated that both health and subjective wellbeing in older age were influenced by childhood IQ and social class, via education. Some older-age personality traits mediated the effects of early-life variables, on subjective wellbeing in particular, but childhood dependability did not show significant associations. Our results therefore did not provide evidence that childhood dependability promotes older-age health and wellbeing, but did highlight the importance of other early-life factors, particularly characteristics that contribute to educational attainment. Further, personality in later life may mediate the effects of early-life factors on health and subjective wellbeing. © 2016 The Authors.

    While neuropsychological deficits are evident among methamphetamine (meth) addicts, they are often unrelated to meth exposure parameters such as lifetime consumption and length of abstinence. The notion that some meth users develop neuropsychological impairments while others with similar drug exposure do not, suggests that there may be individual differences in vulnerability to the neurotoxic effects of meth. One source of differential vulnerability could come from genotypic variability in metabolic clearance of meth, dependent on the activity of cytochrome P450-2D6 (CYP2D6). We compared neuropsychological performance in 52 individuals with a history of meth dependence according with their CYP2D6 phenotype. All were free of HIV or hepatitis C infection and did not meet dependence criteria for other substances. Extensive metabolizers showed worse overall neuropsychological performance and were three times as likely to be cognitively impaired as intermediate/poor metabolizers. Groups did not differ in their demographic or meth use characteristics, nor did they evidence differences in mood disorder or other substance use. This preliminary study is the first to suggest that efficient meth metabolism is associated with worse neurocognitive outcomes in humans, and implicates the products of oxidative metabolism of meth as a possible source of brain injury.

  8. An integrated model of transcription factor diffusion shows the importance of intersegmental transfer and quaternary protein structure for target site finding.

    Directory of Open Access Journals (Sweden)

    Hugo G Schmidt

    Full Text Available We present a computational model of transcription factor motion that explains both the observed rapid target finding of transcription factors, and how this motion influences protein and genome structure. Using the Smoldyn software, we modelled transcription factor motion arising from a combination of unrestricted 3D diffusion in the nucleoplasm, sliding along the DNA filament, and transferring directly between filament sections by intersegmental transfer. This presents a fine-grain picture of the way in which transcription factors find their targets two orders of magnitude faster than 3D diffusion alone allows. Eukaryotic genomes contain sections of nucleosome free regions (NFRs around the promoters; our model shows that the presence and size of these NFRs can be explained as their acting as antennas on which transcription factors slide to reach their targets. Additionally, our model shows that intersegmental transfer may have shaped the quaternary structure of transcription factors: sequence specific DNA binding proteins are unusually enriched in dimers and tetramers, perhaps because these allow intersegmental transfer, which accelerates target site finding. Finally, our model shows that a 'hopping' motion can emerge from 3D diffusion on small scales. This explains the apparently long sliding lengths that have been observed for some DNA binding proteins observed in vitro. Together, these results suggest that transcription factor diffusion dynamics help drive the evolution of protein and genome structure.

    During the 2009 A(H1N1) influenza pandemic, a suite of studies conducted in Canada showed an unexpected finding, that patients with medically attended laboratory-confirmed pandemic influenza were more likely to have received seasonal influenza vaccination than test-negative control patients. Different bodies, including scientific journals and government scientific advisory committees, reviewed the evidence simultaneously to determine its scientific validity and implications. Decision-making was complicated when the findings made their way into the media. The normal trajectory of non-urgent research includes peer-review publication after which decision-makers can process the information taking into account other evidence and logistic considerations. In the situation that arose, however, the congruence of an unexpected finding and the simultaneous review of the evidence both within and outside the traditional peer-review sphere raised several interesting issues about how to deal with emerging evidence during a public health emergency. These events are used in this article to aid discussion of the complex interrelationship between researchers, public health decision-makers and scientific journals, the trade-offs between sharing information early and maintaining the peer-review quality assurance process, and to emphasise the need for critical reflection on the practical and ethical norms that govern the way in which research is evaluated, published and communicated in public health emergencies.

    Despite growing interest and controversy regarding the value of doulas in contemporary maternity care, little is known about the profile of women who choose to involve a doula in their care team. This preliminary analysis indicates that women's attitudes towards maternity care may influence their use of a doula more so than demographic factors. Further research examining these issues in more detail is needed for all those involved in maternity care to ensure safe maternal and fetal outcomes.

    Full Text Available BACKGROUND:Although clinicians in both primary and tertiary care settings are involved in the care of breast cancer patientsfollowing the active treatment phase, few studies report how patients interact with health care providers.METHODS:Participants in this breast cancer follow-up study were recruited from a hospital based nurse-led follow-upclinic in Western Australia. Methods included audio taped, transcribed consultations with Specialist BreastNurses (SBNs and patient self-completed surveys.RESULTS:Preliminary data suggest that SBNs play an important role in supporting women to deal with the impact ofbreast cancer in the years following active treatment. The data suggest that the process of adjustment to adiagnosis of cancer continues for many years after the treatment has ceased. In many cases the women requireon-going support to recalibrate their response to normal physical changes that may or may not be aconsequence of surgery, radiotherapy and chemotherapy.CONCLUSIONS:These preliminary data map the plethora of issues that influence cancer patients in the years followingtreatment. Women who were attending follow-up appointments for breast cancer experienced similar levels ofenablement following SBN consultations as would be expected from consultations with general practitioners.

    Acute emotional arousal moderates the effects of cortisol on memory. However, it is currently unknown how stable inter-individual differences (i.e., traits) moderate cortisol's effects on memory. In two studies using within-subjects designs - 31 healthy males in Study 1 and 42 healthy subjects (22 female) in Study 2 - we measured trait negative affect (NA) and presented emotional and neutral pictures. In Study 1, we manipulated endogenous cortisol levels using a speech stressor following encoding. In Study 2, using a randomized placebo-controlled design, we pharmacologically manipulated cortisol levels prior to encoding (0.1mg/kg hydrocortisone vs. saline infused over 30min). Free recall for pictures was subsequently assessed. Trait NA repeatedly moderated the relationship between cortisol and memory formation. Findings suggested the speculative conclusion that the direction of effects may vary by sex. In males, cortisol was related to memory facilitation in subjects with lower Trait NA. Conversely, females with higher Trait NA showed greater cortisol-related increases in memory. Trait NA may be a stable inter-individual difference predicting neurocognitive effects of cortisol during stressors.

    This study examines performance of schizophrenia patients, unaffected relatives and controls in social cognition, cognitive and psychiatric scales looking for possible markers of vulnerability in schizophrenia. Performance of schizophrenia patients from multiplex families, first-degree relatives, and matched controls was compared and, subsequently, discriminant analysis method was used for identifying the best predictors for group membership. By using Multigroup Discriminant Analyses on the three groups, the best predictors were PANSS, Premorbid Adjustment Scale, Faux Pas test, and a face/emotion categorizing task. This model obtained 82% correct global classification, suggesting that the combination of psychiatric scales and neuropsychological/social cognition tesks are the best approach for characterizing this disease. Although preliminary, our results suggest that social cognition tasks are robust markers of schizophrenia family impairments, and that combining clinical, social and neuropsychological measures is the best approach to asses patients and relatives vulnerability.

    The aim of this study was to compare the effectiveness of work-related cognitive-behavioral treatment (W-CBT) with that of cognitive-behavioral treatment as usual (CBT-AU) for employees on sick leave as a result of a major depressive disorder (MDD). We collected data for 26 matched outpatients at pre- and posttreatment, as well as at 1-year follow-up. Outcome measures were the days of incapacity to work (DIW) as well as self-report measures (Beck Depression Inventory [BDI], Symptom Checklist 90-R [GSI], Life Satisfaction Questionnaire [FLZ]). We analyzed data with hierarchical linear modeling in a 2-level model. Therapy effects were defined in 3 ways: effect size (ES), response (based on the reliable change index), and remission compared with the general population's symptom level. The DIW were reduced significantly after both types of treatment, but employees showed even fewer DIW after W-CBT. At follow-up, significantly more employees were working as a result of W-CBT than with CBT-AU. Significant improvements on scores of self-rating measures corresponded with moderate-to-large effect sizes for both treatment types. Approximately 2 thirds of the treated employees were categorized as unimpaired on BDI scores at posttreatment and at follow-up. At least 1 half of the employees were classified as unimpaired on GSI scores at both assessment points. In future research, a randomized controlled trial should be conducted using a larger sample size to investigate the impact of moderators (e.g., employees at different branches of the company). Findings provided support for using common CBT techniques to enhance return to work without losing expected improvements at the symptom level.

    Full Text Available Soft nanogels are submicron-sized hydrophilic structures engineered from biocompatible polymers possessing the characteristics of nanoparticles as well as hydrogels, with a wide array of potential applications in biotechnology and biomedicine, namely, drug and protein delivery. In this work, nanogels were obtained using the physical self-assembly technique or ‘layer-by-layer’ which is based on electrostatic interactions. Liposomal vesicles were coated with alternating layers of hyaluronic acid and chitosan yielding a more viscous hydrogel formulation that previously reported core-shell nanoparticulate suspension, via simply modifying the physico-chemical characteristics of the system. Structural features, size, surface charge, stability and swelling characteristics of the nanogel were studied using scanning electron microscopy and dynamic light scattering. With a specific cranio-maxillofacial application in mind, the hydrogel was loaded with recombinant human (rh bone morphogenetic protein-7, also known as osteogenic protein-1 or rhOP-1 and release was monitored over an extended period of 60 days. This preliminary study reports promising results on the formulation of a novel core-shell polymeric nanogel.

    Pierre Robin sequence (PRS) is a congenital abnormality that may cause upper airway obstruction requiring surgical intervention. This preliminary study aimed to examine the feasibility and effectiveness of mandible traction with wires for the treatment of upper airway obstruction caused by PRS in Chinese infants. Measures of interest included transcutaneous oxygen saturation before and after surgery, duration of surgery and traction, complications, and CT findings. Seven infants were included in the study (mean birth weight: 2485 g, range: 2405-2570 g); four were born preterm and three were born full term. Mean age at surgery was 13.7 days (range: 2-28 days), mean duration of surgery was 16.6 min (range: 13-25 min) and mean duration of traction was 26.6 days (range: 21-35 days). Mean follow-up was 6.2 months (range: 1-11 months). No infant experienced severe complications. All infants experienced increases in transcutaneous oxygen saturation after surgery. Mean transcutaneous oxygen saturation was 82% before surgery and 98% after surgery. Follow-up morphology of the mandible was excellent. There was no upper airway obstruction, and short-term growth and development were satisfactory. These preliminary findings suggest that mandibular traction with wires may be an effective treatment for upper airway obstruction caused by PRS in Chinese infants.

    Atypical asymmetries of spatial attention have been reported in children with attention deficit hyperactivity disorder (ADHD) and may be exacerbated by non-spatial factors such as attentional capacity. Although preliminary evidence suggests that asymmetries of attention in ADHD may be modifiable by the psychostimulant, methylphenidate, further placebo-controlled studies are required. This study first aimed to confirm recent evidence that increasing non-spatial processing load at fixation can unmask a spatial gradient of target detection in children with ADHD but not Controls. Second, we used placebo-controlled randomised trial methodology to ask whether 20mg of methylphenidate (MPH) could remediate any load-dependent asymmetry of spatial attention in adolescents with ADHD. Twelve male adolescents with ADHD were assessed twice in a double-blind, randomized design, under either placebo or an acute dose of methylphenidate. Thirteen typically developing adolescent Controls completed a single session under placebo. Participants completed a computer-based task in which they monitored a centrally presented rapid serial visual presentation stream for a probe stimulus, while also responding to brief peripheral events. The attentional load of the central task was manipulated by varying the target instructions but not the physical stimuli or the frequency of targets. Between-group analyses under placebo conditions indicated that increased attentional load induced a spatial gradient for target detection in the ADHD but not Controls, such that load slowed response times for left, but not, right hemi-field targets. This load-dependent spatial asymmetry in the adolescents with ADHD was abolished by administration of methylphenidate. Methylphenidate may "normalise" target detection between the hemi-fields in ADHD via enhancement of the right-lateralised ventral attention networks that support non-spatial attention.

    Throughout the past decade, HIV rates in Florida-particularly South Florida, where many Latina seasonal farmworkers reside and work-have ranked among the highest in the nation. In this brief report, we delineate important lessons learned and preliminary findings from the implementation of the HIV prevention intervention Progreso en Salud (Progress in Health). Among the 114 Latina seasonal farmworker participants, there were significant increases from baseline to 6-month follow-up in the percentages of overall condom use, HIV testing, HIV/AIDS-related communications with friends, HIV knowledge, condom use self-efficacy, and correct use of condoms. Lessons learned from this study can be used to inform future HIV intervention strategies to improve the adoption and maintenance of HIV risk reduction behaviors among high-risk Latina seasonal workers and other high-risk underserved populations. Future research is needed to support our findings.

  1. Investigating the possibility of a syntactic impairment in the semantic variant of PPA using a constrained production task: Preliminary findings

    Sentence Type was run for three different measures of sentence production: accuracy on overall production, accuracy on verb morphology and ‘overall grammaticality’ (a measure we devised to reflect a sentence’s grammaticality, irrespective of its semantic content, for each of the three time points. Post hoc testing was performed using the Tukey-Kramer test. For all main effects and interactions, a p-value of less than 0.05 was considered significant. We found that both the nfvPPA and svPPA groups showed a syntactic impairment in this constrained sentence production task. However, the groups demonstrated a different pattern and progression of impairment, with the syntactic impairment initially being generally more severe and pervasive for participants with nfvPPA compared to participants with svPPA. Interestingly, the svPPA group demonstrated a syntactic impairment in the analysis of accuracy of verb morphology that was not observed in the analysis using the less stringent ‘overall grammaticality’ measure. This difference may mirror the differences observed when using constrained versus unconstrained tasks. Overall, the findings from this study contribute important information regarding the nature and progression of the language production impairment in the non-fluent and semantic variants of primary progressive aphasia.

    2010-01-01

    We describe our early experience with use in emergency department settings of a standards-based medication history service integrated into a health information exchange (HIE). The service sends queries from one Exchange’s emergency department interface both to a local ambulatory care system and to the medication hub services provided by a second HIE. This second HIE in turn sends requests to SureScripts and returns histories for incorporation into the first Exchange’s clinical interface. The service caches all requests to avoid costly duplicate query charges and maintains an account of queries, registered users, charges, and results obtained. Usage may be increasing as additional retail pharmacy data become available. Early results suggest that research and development emphasis requirements will of necessity shift from obtaining prescription medication history to finding new means to ensuring effective use.

    Acute inpatient care is not a therapeutic milieu, perhaps owing to the lack of nursing skills. Solution-focused therapy (SFT) has been successful in US inpatient facilities in relation to both objective and subjective 'measures'. This paper reports a study of SFT in a UK context, with the aim of developing a user-friendly SFT training course and assessing its impact on both nurses and clients, via a multifaceted, triangulated data collection design. Nurses' knowledge and clinical performance were assessed, as was the client's perspective. There was a significant difference in nurses' SFT knowledge after training and strong evidence of the model being used in practice during the course of training, although nursing documentation was not fully completed. Eighty-three per cent of nurses said that they would continue using the model, and clients found the SFT approach helpful. The findings match the US experience of using SFT.

    Full Text Available The purpose of this study is to examine the possible benefits of participation in group singing for people with eating disorders in a non-clinical context. The creation of a group singing workshop for women that exhibited disordered eating provided the opportunity to explore the participants’ experiences as perceived by them. A qualitative approach utilizing a semi-structured interview was employed to explore in depth the women’s perceptions regarding the group singing workshop. A thematic analysis of the data identified four main categories concerning the benefits of group singing for the population under study. The theoretical model of Sears (1968 of the processes in music therapy and its application on anorexic clients (Parente 1989 informed the discussion of the empirical findings.

    Full Text Available Abstract Background The impact of infection with HIV on the risk of cancer in children is uncertain, particularly for those living in sub-Saharan Africa. In an ongoing study in a paediatric oncology centre in Malawi, children (aged ≤ 15 years with known or suspected cancers are being recruited and tested for HIV and their mothers or carers interviewed. This study reports findings for children recruited between 2005 and 2008. Methods Only children with a cancer diagnosis were included. Odds ratios (OR for being HIV positive were estimated for each cancer type (with adjustment for age ( Results Of the 586 children recruited, 541 (92% met the inclusion criteria and 525 (97% were tested for HIV. Overall HIV seroprevalence was 10%. Infection with HIV was associated with Kaposi sarcoma (29 cases; OR = 93.5, 95% CI 26.9 to 324.4 and with non-Burkitt, non-Hodgkin lymphoma (33 cases; OR = 4.4, 95% CI 1.1 to 17.9 but not with Burkitt lymphoma (269 cases; OR = 2.2, 95% CI 0.8 to 6.4. Conclusions In this study, only Kaposi sarcoma and non-Burkitt, non-Hodgkin lymphoma were associated with HIV infection. The endemic form of Burkitt lymphoma, which is relatively frequent in Malawi, was not significantly associated with HIV. While the relatively small numbers of children with other cancers, together with possible limitations of diagnostic testing may limit our conclusions, the findings may suggest differences in the pathogenesis of HIV-related malignancies in different parts of the world.

    Subjects with post-traumatic stress disorder (PTSD) present a diminished or blunted emotional response, sometimes called "emotional numbing" (EN), that constitutes one of the central symptoms in PTSD. Symptoms of EN include diminished interest in activities, feeling detached or estranged from others, and restricted range of affect (American Psychiatric Association, 2000). The present work studied the emotional components in individuals with PTSD with the principal aim of investigating subjects' functional alteration in the limbic regions, insula and frontal cortex during an emotional task compared with healthy subjects. Ten subjects with PTSD (survivors of the 6.3 magnitude earthquake of April 6, 2009 in L'Aquila) and ten healthy controls underwent fMRI. PTSD was diagnosed according to DSM-IV-R (APA 2000). All subjects underwent fMRI while viewing content-neutral and emotional stimuli. Data analysis revealed that PTSD subjects had significantly greater cerebral activation in particular in the right anterior insula and in bilateral inferior frontal gyrus. Our data suggest that there is a change in the activation of brain areas responsible for emotional processing in patients with PTSD and are consistent with previous findings demonstrating hyperactivation in frontolimbic structures during emotional tasks. Our study suggests that close personal experience may be critical in engaging the neural mechanisms underlying the emotional modulation of memory. Our findings provide evidence that significant alterations in brain function, similar in many ways to those observed in PTSD, can be seen shortly after major traumatic experiences, highlighting the need for early evaluation and intervention for trauma survivors.

    An 81-year-old Japanese man with jaundice was strongly suspected clinically of having primary sclerosing cholangitis based on clinical examinations and later died of hepatic failure. The entire course of the disease lasted about 10 mo. The autopsy revealed extensive fibrinoid necrosis in the liver, kidney, spleen, pancreas,lung, lymph nodes, and pleura. Particularly extensive fibrinoid necrosis in the portal tracts of the liver induced severe stenoses of the intrahepatic bile ducts, resulting in cholestasis in association with prominent liver injury.There were no findings indicating primary sclerosing cholangitis. The hepatic lesions in this case did not coincide with any known disease including collagen diseases. To clarify the cause of irregular stenoses of the intrahepatic biliary trees on cholangiographic findings, we postulate that some form of immunological derangement might be involved in pathogenesis of fibrinoid necrosis.However, the true etiology remains unknown.

    Extracellular RNAs (exRNAs) have been identified in all tested biofluids and have been associated with a variety of extracellular vesicles, ribonucleoprotein complexes and lipoprotein complexes. Much of the interest in exRNAs lies in the fact that they may serve as signalling molecules between cells, their potential to serve as biomarkers for prediction and diagnosis of disease and the possibility that exRNAs or the extracellular particles that carry them might be used for therapeutic purposes. Among the most significant bottlenecks to progress in this field is the lack of robust and standardized methods for collection and processing of biofluids, separation of different types of exRNA-containing particles and isolation and analysis of exRNAs. The Sample and Assay Standards Working Group of the Extracellular RNA Communication Consortium is a group of laboratories funded by the U.S. National Institutes of Health to develop such methods. In our first joint endeavour, we held a series of conference calls and in-person meetings to survey the methods used among our members, placed them in the context of the current literature and used our findings to identify areas in which the identification of robust methodologies would promote rapid advancements in the exRNA field.

    Full Text Available Leukocyte telomere length (LTL shortens with age, and is a prospective marker of mortality related to cardiovascular disease. Many health behaviors and social environmental factors have been found to be associated with LTL. Several of these are also associated with conscientiousness, a dispositional personality trait. Conscientiousness is a propensity to be planful, adhere to social norms, and inhibit pre-potent responses. Like LTL, conscientiousness is prospectively related to mortality, possibly through cumulative effects on health over the life course via multiple pathways. As a result, we hypothesized that childhood levels of conscientiousness would predict LTL prospectively in adulthood. We selected a sample of 60 women in the Hawaii Personality and Health Cohort; 30 described by their teachers as high on conscientiousness in childhood and 30 described as low on the trait. Dried blood spot samples collected in adulthood 40 years later were used as sources of DNA for the LTL assay. Conscientiousness was associated with longer LTL (p = .02. Controlling for age did not account for this association. Controlling for education and physiological dysregulation partially attenuated the association, and the effect remained significant when accounting for differences in LTL across cultural groups. These results represent the first evidence that childhood personality prospectively predicts LTL 40 years later in adulthood. Our findings would be consistent with a mediation hypothesis whereby conscientiousness predicts life paths and trajectories of health that are reflected in rates of LTL erosion across the lifespan.

    This study sought to clarify the effects of bupropion SR on anterior paralimbic function in depressed patients by studying changes in the activation of these structures from waking to REM sleep both before and after treatment. Twelve depressed patients underwent concurrent EEG sleep studies and [18F]fluoro-2-deoxy-D-glucose ([18F]-FDG) positron emission tomography (PET) scans during waking and during their second REM period of sleep before and after treatment with bupropion SR. Nine subjects completed pre- and post-treatment waking PET studies. Five subjects completed pre- and post-treatment waking and REM sleep PET studies. Bupropion SR treatment did not suppress electrophysiologic measures of REM sleep, nor did it alter an indirect measure of global metabolism during either waking or REM sleep. Bupropion SR treatment reversed the previously observed deficit in anterior cingulate, medial prefrontal cortex and right anterior insula activation from waking to REM sleep. In secondary analyses, this effect was related to a reduction in waking relative metabolism in these structures following treatment in the absence of a significant effect on REM sleep relative metabolism. The implications of these findings for the relative importance of anterior paralimbic function in REM sleep in depression and for the differential effects of anti-depressant treatment on brain function during waking vs. REM sleep are discussed.

    Highlights: • Purely intra-epiphyseal stress injuries of the proximal tibial epiphysis are described for the first time. • The variation in the MRI findings of these injuries depending on the stage of maturation is demonstrated. • We postulate a patho-mechanism to explain the variations in site and appearance of stress injuries in this region. - Abstract: Stress induced injuries affecting the physeal plate or cortical bone in children and adolescents, especially young athletes, have been well described. However, there are no reports in the current English language literature of stress injury affecting the incompletely ossified epiphyseal cartilage. We present four cases of stress related change to the proximal tibial epiphysis (PTE) along with their respective magnetic resonance imaging (MRI) appearances ranging from subtle oedema signal to a pseudo-tumour like appearance within the epiphyseal cartilage. The site and pattern of intra-epiphyseal injury is determined by the type of tissue that is affected, the maturity of the skeleton and the type of forces that are transmitted through the tissue. We demonstrate how an awareness of the morphological spectrum of MRI appearances in intra-epiphyseal stress injury and the ability to identify concomitant signs of stress in other nearby structures can help reduce misdiagnosis, avoid invasive diagnostic procedures like bone biopsy and reassure patients and their families.

    This paper discusses an experimental approach to examine uranium exploration avenue over the geologicallyextended parts of Mahadek basin in Meghalaya, amid some of the environmental constraints. Studycomprises periodic measurements of prevailing ambient gamma levels across 320 georeference points, inrelation to the major litho units of Mahadek basin, covering 673 line km of Khasi Hills. Acquired sampledata points were then analysed in geostatistical software (Surfer^{TM}) to develop analytical model of samplevariogram having bearing on the uranium exploration in the area. Study findings have given encouragingsurface indicators with mostly elevated gamma levels over the parts of West Khasi Hills. Delineatedgamma anomalous zones are lithologically well correlated including to that of existing uranium occurrencesin the basin. Identified anomalous zones over the parts of West Khasi Hills by this study work, aremainly associated with the Mahadek sandstone (Upper and Lower Mahadek) and Precambrian basementgranites. Lower Mahadek sandstone is host rock for uranium mineralisation in the basin. Initial findingssuggest with the closer spatial resolution (∼1 km) of sample data points, the approach adopted by thestudy work holds promising application in locating potential uranium exploration targets especially tothe extended and inaccessible parts of the basin.

    The effect of snus use on smoking behaviors among US young adults is largely unknown. Data from the Minnesota Adolescent Community Cohort Study collected in 2010 to 2011 and 2011 to 2012 (participants aged 20-28 years) showed that young adult nonsmokers who had tried snus were subsequently more likely than those who had not tried snus to become current smokers (n = 1696; adjusted odds ratio = 1.79; 95% confidence interval = 1.01, 3.14). Snus use was not associated with subsequent smoking cessation or reduction among young adult current smokers (n = 488; P > .46).

    Full Text Available Abstract Background To determine the prevalence of asthma symptoms in a sample of Greek children aged 10–12 years, and to evaluate these rates in relation to anthropometric, lifestyle characteristics and dietary habits. Methods During 2006, 700 schoolchildren (323 male and 377 female, aged 10–12 years (4th to 6th school grade, were selected from 18 schools located in the greater Athens area. The schools were randomly selected from a list provided by the regional educational offices. To achieve a representative sample the schools enrolled were selected from various region of the Athens area. For each child a questionnaire was completed that was developed for the purposes of the study to retrieve information on: age, sex, school class, other socio-demographic characteristics, anthropometric measurements, dietary habits (through a semi-quantitative Food Frequency Questionnaire and physical activity status; the presence of asthma and allergies was assessed by the standard ISAAC questionnaire. Results The prevalence of wheezing in the past was 25% in boys and 19% in girls, while the prevalence of current wheezing was 9.0% in boys and 5.8% in girls. The prevalence of any asthma symptoms was 27.6% in boys and 20.4% in girls. Multiple logistic regression analysis revealed that increased body weight and sedentary lifestyle is associated with asthma symptoms only in boys. Conclusion The present cross-sectional study cannot establish causal relationships between asthma and increased body weight of schoolchildren; however, our findings underline the associations between asthma, increased body weight, and physical activity at population level, and urge for actions that should be taken by public health policy makers in order to prevent these conditions among children.

    Full Text Available BACKGROUND: There are sparse data on whether non-pharmaceutical interventions can reduce the spread of influenza. We implemented a study of the feasibility and efficacy of face masks and hand hygiene to reduce influenza transmission among Hong Kong household members. METHODOLOGY/PRINCIPAL FINDINGS: We conducted a cluster randomized controlled trial of households (composed of at least 3 members where an index subject presented with influenza-like-illness of <48 hours duration. After influenza was confirmed in an index case by the QuickVue Influenza A+B rapid test, the household of the index subject was randomized to 1 control or 2 surgical face masks or 3 hand hygiene. Households were visited within 36 hours, and 3, 6 and 9 days later. Nose and throat swabs were collected from index subjects and all household contacts at each home visit and tested by viral culture. The primary outcome measure was laboratory culture confirmed influenza in a household contact; the secondary outcome was clinically diagnosed influenza (by self-reported symptoms. We randomized 198 households and completed follow up home visits in 128; the index cases in 122 of those households had laboratory-confirmed influenza. There were 21 household contacts with laboratory confirmed influenza corresponding to a secondary attack ratio of 6%. Clinical secondary attack ratios varied from 5% to 18% depending on case definitions. The laboratory-based or clinical secondary attack ratios did not significantly differ across the intervention arms. Adherence to interventions was variable. CONCLUSIONS/SIGNIFICANCE: The secondary attack ratios were lower than anticipated, and lower than reported in other countries, perhaps due to differing patterns of susceptibility, lack of significant antigenic drift in circulating influenza virus strains recently, and/or issues related to the symptomatic recruitment design. Lessons learnt from this pilot have informed changes for the main study in 2008

    Full Text Available Food is exposed to light during processing, packaging, distribution and retail storage, resulting in deterioration of the product quality. Milk and other dairy products are among the most sensitive due to the high content of riboflavin, vitamin B2, which is an efficient photosensitizer for oxidative processes. Photooxidation in cheese induces degradation of nutritional quality such as proteins, lipids, and vitamins. Moreover, it causes formation of off-flavours, off-odours and gradual bleaching. The objective of this study was to evaluate the effect of light exposition on sliced Asiago d’allevo cheese (lowland vs alpine aerobically packaged stored for 336 h under both fluorescent light and in the dark. Alpine cheese showed higher b* (P<0.001 and a* indexes (P<0.001 and also a higher lipid oxidation (P<0.01 than lowland one. Riboflavin content was significantly higher (P<0.001 in lowland cheese. Cheese samples exposed to the light were significantly lighter (P<0.001 than those exposed in the dark and they also showed a decrease in yellowness (P<0.001 and redness (P<0.001 as well as in riboflavin content (P<0.001. Lipid oxidation did not produce statistically significant change. Storage time significantly affected riboflavin content (P<0.001, TBARs (P<0.001 and cheese colour (P<0.001. Results suggest that light exposition had a pronounced effect on cheese characteristics.

    Thick clay deposits in a recently identified paleo-lake bed in a central Appalachian karst system in Highland County, Virginia have yielded well-preserved pollen and macroflora that provide the opportunity to refine the understanding of Pleistocene climate, vegetation dynamics, and erosion in the region. A radiocarbon date of 22,000 14C yr B.P. on wood fragments near the top of the sequence establishes the age of the sediments. Pollen and plant macrofloras characteristic of modern boreal forests are present in sediments at this site. Pollen assemblages show a dominance of conifers, mostly Pinus banksiana and Picea, with Lycopodium as important ground cover. Leaf fossils sieved from the clay show a dominance of Picea needles and common dicot leaf fragments, suggesting that Pinus is either over-represented in the pollen flora or more distal to the paleo-lake. Macrofossil assemblages sieved from the clay contain a variety of non-leaf remains, including fruits, seeds, mosses, insects, feathers, and fungi. Test augering and geophysical results indicate that these clay deposits are at least 9m and perhaps as much as 15m thick. The amount and temporal distribution of sediment loads to the paleo-lake (a depositional environment) from the surrounding landscape (an erosional environment) will be modeled using analysis of sediment facies in and above (>12m) these clays, combined with sediment volume calculations and drainage basin analysis, and constrained by dates from the sediments themselves. Due to the rare occurrence of still-water depositional environments in the Appalachians, this site provides paleo-climate and sedimentological data that will refine regional models of landscape evolution and incision. This work also has implications for the development and modification of a significant karst system that surrounds and underlies the paleo-lake bed. The same karst system is responsible both for the formation of the paleo-lake (after the drain in a blind valley became

    Full Text Available Cameron Highlands was discovered in 1885 and was developed as a hill station. It first served as a quaint retreat destination for the British residence where the urban morphology of its little town centres were strongly characterised by colonial architecture such as bungalows, institutional buildings and government offices, shophouses and market stalls. Eventually due to economic pressure and location potentials, more land was opened for tea plantations and vegetable and flower industries. Conversely, recent rapid uncontrolled developments in the built environment and agricultural sectors have tarnished its natural environment, old-world charm and historical values.\tIf this trend persists, the popularity of Cameron Highlands as a vacation destination for local and foreign visitors may be badly affected. This research paper seeks to determine the perception of local stakeholders and tourists of the development in Cameron Highlands and whether they agree that agro-ecotourism can be used as a tool to achieve sustainability in the area. This paper is an assessment of a pilot test to determine initial perceptions toward Cameron Highlands development. The pilot test sample size was 41 respondents, comprising local authorities, local communities and NGOs, as well as local and international tourists. The results showed that the majority agreed that agro-ecotourism can generate a sustainable income and preserve the environment while ensuring sustainability through fair trade.

(3) On the northwestern flank of the Gretater Aladaǧ, about twenty lava flows are exposed. These aphyric lavas consist of Plg and Opx. (4) The aphyric lavas of the Lesser Aladaǧ, in the northwest of the Greater Aladaǧ volcano, are basaltic andesitic in composition. In the northeast of the study area, Upper Pliocene lavas exposed on the southern edge of the Kars plateau are the youngest volcanic units which are basaltic in composition displaying porphyritic textures in the study area. They are composed of plagioclase and clinopyroxene phenocrysts. Volcanic products in the study area are calc-alkaline in character with a clear subduction signature. They show textures characteristic for magma mixing processes indicating periodic replenishment of magma chamber by primitive basaltic magmas. Our assimilation models indicate that AFC was an important process for the evolved lavas. However, AFC remained negligible during the magma chamber evolution of the basic volcanic units.

    We seek methods of stimulating young school children to develop an interest in science and engineering through a natural curiosity for the reaction of light. Science learning now begins fully at middle school. Reading skills develop with activity at home and progress through the elementary school curriculum, and in a like manner, a curious interest in science also should begin at that stage of life. Within the ranks of educators, knowledge of optical science needs to be presented to elementary school students in an entertaining manner. One such program used by the authors is Doug Goodman's Optics Demonstrations With the Overhead Projector, co-published by and available from OSA (Optical Society of America) and SPIE-The International Society of Optical Engineering. These demonstrations have been presented in middle and high schools; however, as a special approach, the authors have developed selected Goodman demonstrations as a "Magic Show of Light" for elementary schools. Teachers in the U.S. are overloaded with classroom instruction specifically targeted at improving reading and math scores on the Standard Achievement Test (SAT); therefore, science is getting "short changed" in the education system. For the sake of our future, industry volunteers must come forward to promote interest in science beginning with K-6.

    Rett syndrome (RS) is a severe progressive neurological disorder occurring exclusively in females. Most cases are sporadic. The few familial cases (less than 1%) cannot be explained by a simple mode of inheritance. Several hypotheses have been proposed: X-linked male lethal mutation, maternal uniparental disomy, fresh mutation on the X chromosome, involvement of mitochondrial DNA and differential inactivation with metabolic interference of X-borne alleles. The authors have examined the pattern of X inactivation in 10 affected girls who were selected according to the clinical criteria previously described and accepted by the French Rett Scientific Committee. The X inactivation pattern was studied by analysis of methylation at the hypervariable locus DXS255 with the M27{beta} probe. The results show a more-or-less skewed inactivation of paternal X in 8 Rett females, and 2 cases of symmetrical inactivation. In control girls, inactivation was symmetrical cases and the maternal X has been preferentially inactivated in the other 2 cases. In no case was a total skewed inactivation observed. Though there was clear evidence for a preferential paternal X inactivation that was statistically significant further studies are necessary to establish a relationship between X inactivation pattern and Rett syndrome.

    The arts offer alternative insights into reality, which are explored by science in general, and broadened by the activities conducted by the European Space Agency [4] and other space agencies. Similar to the way the members of ESA are ambassadors for spaceflight and science, artists and cultural professionals are ambassadors for human expression, experimentation, and exploration. In June 2011, the ESA Topical Team Arts and Sciences (ETTAS) held a three-day workshop at the European Astronaut Centre in Cologne, Germany. During this workshop, topics and ideas were discussed to develop initiatives between the arts, sciences and ESA. The aim was to foster and expand the human and cultural aspects of space exploration, and at the same time offer a means of communication that aims to reach audiences beyond the scope of traditional space-related channels. The consensus of the team was that establishing and sustaining a transdisciplinary professional community consisting of ESA representatives, scientists and artists would fuel knowledge transfer, and mutual inspiration. Potential ways to provide a sustainable cooperation within and between the various groups were discussed. We present the preliminary findings including a number of measures and mechanisms to initiate and conduct such an initiative. Plausible organisational measures, procedures and consequences, as well as a proposition on how to proceed are also discussed. Overall, the involvement and cooperation between the arts, space science research and ESA will enhance in the citizens of the ESA member states the sense of public ownership of ESA results, and participation in ESA's research.

Pre- and post-test data utilizing the Chinese Positive Youth Development Scale (CPYDS) and post-test subjective outcome evaluation data were collected from 546 students who participated in the 20 h Tier 1 Program of the P.A.T.H.S. Project. Results showed that high proportions of the respondents had positive perceptions of the program and the instructors, with 85.3% of the respondents regarding the program as helpful to them. Positive changes in the program participants in many measures of positive youth development were also observed. Although there were some increases in problem behavior in some areas, adolescent problem behavior was generally stable. The present study provides preliminary support for the effectiveness of the Tier 1 Program of the Project P.A.T.H.S. in Hong Kong.

    To test the hypothesis that cognitive impairment may be present early in the course of HTLV-III/LAV infection, intravenous drug abusers (IDVAs) without overt symptoms of AIDS related illness were tested with standard neuropsychological and psychosocial measures. This study is the baseline for a prospective longitudinal study of the natural history of HTLV-III/LAV infection in this high risk population. Of 211 subjects initially evaluated, 70 (33%) were HTLV-III/LAV seropositive and 141 (67%) were seronegative. At the baseline, by univariate analysis, the seropositive IVDAs were significantly (p less than .05) more impaired than seronegatives on 4 of 8 measures: Finger Tapping--dominant, hand, Digit Span Forward, Trail making A and WAIS-Similarities. However, by multivariate analysis the seropositives were significantly more impaired only on the WAIS-Similarities and Wechsler--Associative Learning tests. Multiple factors such as drug use and psychological stress may have influenced test performance. These preliminary results, however, suggest that seropositive IVDAs may show evidence of impaired neuropsychological function even in the absence of AIDS related symptoms and are consistent with the hypothesis of the early neurotropism of HTLV-III/LAV.

    ECG-gated MDCT of the entire chest represents the latest technical advance in the diagnostic work-up of atypical chest pain. The authors report their preliminary experience with the use of 40 and 64-slice CT in the emergency room and recommend to study only patients with moderate likelihood of coronary artery disease. ECG-gated MDCT of the entire chest will be preferentially performed on 64-slice MDCT rather than 40-slice MDCT because it enable to reduce the scan time (18 seconds versus 28 seconds acquisition time), the volume of contrast medium (82 mL + 15 mL versus 97 mL + 15 mL of highly concentrated contrast agent for a patient of 70 kgs) and radiation exposure (17 mSv versus 19 mSv). Approximately 1500 to 2000 of images are produced and need to be analysed on a dedicated workstation by a radiologist expert in cardiac and thoracic disorders. At the present time, only a few studies exist in the literature showing some promising results but further large clinical studies are needed before to implement such sophisticated protocol in emergency room.

    Full Text Available BackgroundThe hypothesis that fibre width is a major determinant of mesothelioma induction has been examined by comparative studies of two crocidolites from different sources. Fine fibres fromCapesouthAfricaand the thicker fibre found and used similarly inBolivia. It is well established that ‘thin’ fibre crocidolite fromCapeSouth Africais extremely mesotheliomagenic. Bolivian crocidolite has a much wider width distribution and relatively little mesothelioma inducing potential. MethodsWe analysed the mesothelioma demography inBoliviawhere local crocidolite has been used for decades This was compared with the mesothelioma demography in theItalianCityof Casale Monteferrato whereCapecrocidolite was processed for many decades in the Eternit Asbestos Cement plant producing numerous cases of mesothelioma.We also conducted a limited downwind study from the fiberizing part of the historical operating plant where products containing Bolivian crocidolite were made for sale and use inCochabamba. ResultsThe demographic study confirmed the absence of a significant mesothelioma excess inBolivia.Despite the extremely high fibre concentrations measured in the plant, no significant fibre levels were detected 100 meters away. Conclusion These preliminary findings undermine claims such as those made at Casale that crocidolite fibre can drift up to 15 km and remain airborne in quantities sufficient to contribute significantly to mesothelioma induction. We propose the difference in thickness and the attendant reduction in the percentage ofStantonfibres provides an explanation for the difference in mesothelioma patterns found in each city.

    Full Text Available BackgroundHigher cancer morbidity and mortality rates for the Indigenous population comparedto the overall Australian population has underlined the critical need to improve accessfor Aboriginal people to cancer treatment services. This paper describes anIndigenous Women’s Cancer Support Group (IWCSG established to supportIndigenous people with cancer and their carers/relatives and to facilitate Aboriginalaccess to cancer screening and treatment. Preliminary findings from an evaluation ofthe group are presented.MethodsThe study employed qualitative research methods to describe IWCSG operations andinvestigate the group’s effectiveness. It included one-on-one interviews with 11Geraldton-based health service providers, the IWCSG coordinator, and 10 womenwho have been linked to IWCSG support, as well as observation of group meetings.ResultsDescriptive outcomes relate to group operations, group effectiveness, group benefitsand future development of the group. A cultural strength of IWCSG is its ability tooperate confidentially behind the scenes, providing emotional support and practicalhelp directly to Indigenous people concerned about privacy and shame issues. Theimportant cultural role IWCSG plays in overcoming communication and othercultural barriers to accessing cancer treatment was unanimously recognised by healthservice providers. Aboriginal women supported by IWCSG spoke about an increasedsense of safety, trust and support in accessing and navigating mainstream cancerservices. A critical issue emerging from the research is the need for further development of effective collaborative working relationships between IWCSGmembers and health service providers.ConclusionsThe IWCSG has the potential to inform an effective model for facilitating Indigenousaccess both to cancer treatment and to mainstream treatment for a variety of healthproblems. Future research is required to explore the applicability of Indigenoussupport groups and to focus on the

    Full Text Available Rationale: Varenicline, the most effective single agent for smoking cessation, is a partial agonist at α4β2 nicotinic acetylcholine receptors. Increasing evidence implicates glutamate in the pathophysiology of addiction and one of the benefits of treatment for smoking cessation is the ability to regain cognitive control. Objective: To evaluate the effects of 12 week varenicline administration on glutamate levels in the dorsal anterior cingulate cortex (dACC and functional changes within the cognitive control network.Methods: We used single-voxel proton magnetic resonance spectroscopy (1H-MRS in the dACC and functional MRI (fMRI during performance of a Stroop color-naming task before and after smoking cessation with varenicline in 11 healthy smokers (open label design. Using the dACC as a seed region, we evaluated functional connectivity changes using a psychophysiological interaction (PPI analysis. Results: We observed a significant decrease in dACC glutamate + glutamine (Glx/Cr levels as well as significant blood oxygen level-dependent signal (BOLD decreases in the rostral ACC/medial orbitofrontal cortex and precuneus/posterior cingulate cortex. These BOLD changes are suggestive of alterations in default mode network (DMN function and are further supported by the results of the PPI analysis that revealed changes in connectivity between the dACC and regions of the DMN. Baseline measures of nicotine dependence and craving positively correlated with baseline Glx/Cr levels.Conclusions: These results suggest possible mechanisms of action for varenicline such as reduction in Glx levels in dACC and shifts in BOLD activities between large scale brain networks. They also suggest a role for ACC Glx in the modulation of behavior. Due to the preliminary nature of this study (lack of control group and small sample size, future studies are needed to replicate these findings.

    Combustion of solid biomass fuels is a major source of household energy in developing nations. Black (BC) and organic carbon (OC) aerosols are the major PM2.5 (particulate matter with aerodynamic diameter smaller than 2.5 μm) pollutants co-emitted during burning of these fuels. While the optical nature of BC is well characterized, very little is known about the properties of light-absorbing OC (LAOC). Here, we report our preliminary findings on the mass-based optical properties of LAOC emitted from the combustion of four commonly used solid biomass fuels - fuel-wood, agricultural residue, dung-cake, and mixed - in traditional Indian cookstoves. As part of a pilot field study conducted in central India, PM2.5 samples were collected on Teflon filters and analyzed for their absorbance spectra in the 300-900 nm wavelengths at 1 nm resolution using a UV-Visible spectrophotometer equipped with an integrating sphere. The mean mass absorption cross-sections (MAC) of the emitted PM2.5 and OC, at 550 nm, were 0.8 and 0.2 m2 g-1, respectively, each with a factor of ~2.3 uncertainty. The mean absorption Ångström exponent (AǺE) values for PM2.5 were 3±1 between 350 and 550 nm, and 1.2±0.1 between 550 and 880 nm. In the 350-550 nm range, OC had an AǺE of 6.3±1.8. The emitted OC mass, which was on average 25 times of the BC mass, contributed over 50% of the aerosol absorbance at wavelengths smaller than 450 nm. The overall OC contribution to visible solar light (300-900 nm) absorption by the emitted particles was 26-45%. Our results highlight the need to comprehensively and accurately address: (i) the climatic impacts of light absorption by OC from cookstove emissions, and (ii) the uncertainties and biases associated with variability in biomass fuel types and combustion conditions, and filter-based measurement artifacts during determination of MAC values.

    Background Annually about 1,700,000 women undergo breast biopsies with an estimated cost of $3.5 billion. About 80% of women are diagnosed with benign conditions (BCs). Other concerns are psychological impact and possible complications of radiographic evaluation of future mammograms. A recent report in the New York Times described the high rate of breast biopsies as diagnostic overkill, drastic and expensive. We report the preliminary findings on pathologic outcomes and predictive probability of sub-classifications of Breast Imaging Reporting and Data System-4 (BIRADS 4). Methods We identified a total of 6,198 women with mammographic classification of BIRADS 4 between 1/1/2009-10/31/2011. So far, demographic, clinical and pathology data have been retrieved for a total of 624 women. Women were broadly stratified by their pathologic outcome into BCs of no clinical significance, proliferative conditions (PCs), and malignant lesions (MLs). Only final pathologic diagnosis was considered. All statistical analyses were performed using SAS v. 9.1. Results A total of 157 women had opted against biopsy and therefore were excluded from further analysis. Of the remaining 467 women, 68.6% (n=322) were diagnosed with BCs, 9.6% (n=45) with PCs, and 21.3% (n=100) with MLs. Women diagnosed with MLs were older (63.5± 13.7) than women with PCs (61.5 ± 13.6) or women with BCs (56.2 ± 11.6) (P<.001). The difference in distributions of the other risk factors, breast density, family history, previous biopsy, use of postmenopausal hormones or body mass index, did not reach statistical significance among the 3 groups. A total of 104 women were sub-classified into 4A (n=65), 4B (n=16) and 4C (n=23). Our initial multivariate logistic regression suggested no statistically significant difference in the risk of breast cancer between women in 4A and 4B classification (P=.35). Final analysis suggested older age (OR=1.08, 95% CI 1.02–1.10, P=.01) was the best predictor of 4C. Our analysis

    Studies of adults with attention-deficit/hyperactivity disorder (ADHD) have suggested that they have deficient response inhibition, but findings concerning the neural correlates of inhibition in this patient population are inconsistent. We used the Stop-Signal task and functional magnetic resonance imaging (fMRI) to compare neural activation associated with response inhibition between adults with ADHD (N=35) and healthy comparison subjects (N=62), and in follow-up tests to examine the effect of current medication use and symptom severity. There were no differences in Stop-Signal task performance or neural activation between ADHD and control participants. Among the ADHD participants, however, significant differences were associated with current medication, with individuals taking psychostimulants (N=25) showing less stopping-related activation than those not currently receiving psychostimulant medication (N=10). Follow-up analyses suggested that this difference in activation was independent of symptom severity. These results provide evidence that deficits in inhibition-related neural activation persist in a subset of adult ADHD individuals, namely those individuals currently taking psychostimulants. These findings help to explain some of the disparities in the literature, and advance our understanding of why deficits in response inhibition are more variable in adult, as compared with child and adolescent, ADHD patients.

    In order to assess the relationships among borderline personality disorder features, non-suicidal self-injury (NSSI) and emotion dysregulation, 122 community-dwelling Italian adolescents were administered by the Italian translations of the Borderline Personality Features Scale for Children-11, the Deliberate Self-Harm Inventory and the Difficulties in Emotion Regulation Scale (DERS). Regression models showed that both Deliberate Self-Harm Inventory (DSHI) and DERS scores significantly predicted Borderline Personality Features Scale for Children-11 total score; moreover, the DSHI total score significantly predicted the DERS total score. Our findings suggest that borderline personality features in adolescence are moderately, albeit significantly related to NSSI, and that emotion dysregulation does not completely account for the association between borderline personality features and NSSI, although it seems to explain a non-trivial proportion of this relationship.

    Full Text Available This study examines the population genetic structure of Tor tambroides, an important freshwater fish species in Malaysia, using fifteen polymorphic microsatellite loci and sequencing of 464 base pairs of the mitochondrial cytochrome c oxidase I (COI gene. A total of 152 mahseer samples were collected from eight populations throughout the Malaysia river system. Microsatellites results found high levels of intrapopulation variations, but mitochondrial COI results found high levels of interpopulations differentiation. The possible reasons for their discrepancies might be the varying influence of genetic drift on each marker or the small sample sizes used in most of the populations. The Kelantan population showed very low levels of genetic variations using both mitochondrial and microsatellite analyses. Phylogenetic analysis of the COI gene found a unique haplotype (ER8*, possibly representing a cryptic lineage of T. douronensis, from the Endau-Rompin population. Nevertheless, the inclusion of nuclear microsatellite analyses could not fully resolve the genetic identity of haplotype ER8* in the present study. Overall, the findings showed a serious need for more comprehensive and larger scale samplings, especially in remote river systems, in combination with molecular analyses using multiple markers, in order to discover more cryptic lineages or undescribed “genetic species” of mahseer.

    The objective of this paper is to adapt attachment-based family therapy (ABFT) for use with suicidal lesbian, gay, and bisexual (LGB) adolescents and to obtain preliminary data on the feasibility and efficacy of the treatment with this population. In Phase I, a treatment development team modified ABFT to meet the unique needs of LGB suicidal youth. In Phase II, 10 suicidal LGB youth were offered 12 weeks of LGB sensitive ABFT. Adolescents' report of suicidal ideation, depressive symptoms, and maternal attachment-related anxiety and avoidance were gathered at pretreatment, 6 weeks, and 12 weeks (posttreatment). In Phase I, the treatment was adapted to: (a) include more individual time working with parents in order to process their disappointments, pain, anger, and fears related to their adolescent's minority sexual orientation; (b) address the meaning, implications, and process of acceptance; and (c) heighten parents' awareness of subtle yet potent invalidating responses to their adolescents' sexual orientation. Results of Phase II suggest this population can be recruited and successfully treated with a family based therapy, evidenced by high levels of treatment retention and significant decreases in suicidal ideation, depressive symptoms, and maternal attachment-related anxiety and avoidance. This is the first family-based treatment adapted and tested specifically for suicidal LGB adolescents. Though promising, the results are preliminary and more research on larger samples is warranted.

    We selected seven aftershocks from Maule earthquake between 33.5°S to 35°S from May to September to find single source inversion. The data were provided by XY Chile Ramp Experiment* which was deployed after great Maule earthquake. Waveform data are from 13 broad band stations chosen from the 58 broad band stations deployed by IRIS-PASCAL from April to September 2010. Stations are placed above the normal subduction section south of ~33.5°S. Events were located with an iterative software called Hypocenter using one dimensional local model, obtained above for the forearc region between 33°S to 35°S. We used ISOLA which is a fortran code with a Matlab interface to obtain moment tensors solutions, optimum position and time of the subevents. Values depth obtained by a grid search of centroid position show range values which are compatibles with the interplate seismogenic zone. Double-Couple focal mechanism solutions (Figure 1) show 4 thrust events which can be associated with that zone. However, only one of them has strike, dip and rake of 358°, 27° and 101 respectively, appropriate to be expected for interplate seismogenic zone. On the other hand, the other 3 events show strike and normal double-couple focal mechanism solutions (Figure 1). This last topic makes association to those events to the contact of the Nazca and South American plate difficult. Nevertheless, in a first stage, their depths may allow possibility of an origin there. * The facilities of the IRIS Data Management System, and specifically the IRIS Data Management Center, were used for access to waveform, metadata or products required in this study.

    The dopamine theory proposes the relationship of delusions to aberrant signaling in striatal circuitries that can be normalized with dopamine D2 receptor-blocking drugs. Localization of such circuitries, as well as their upstream and downstream signaling, remains poorly known. We collected functional magnetic resonance images from first-episode psychosis patients and controls during an audiovisual movie. Final analyses included 20 patients and 20 controls; another sample of 10 patients and 10 controls was used to calculate a comparison signal-time course. We identified putamen circuitry in which the signal aberrance (poor correlation with the comparison signal time course) was predicted by the dopamine theory, being greater in patients than controls; correlating positively with delusion scores; and correlating negatively with antipsychotic-equivalent dosage. In Granger causality analysis, patients showed a compromised contribution of the cortical salience network to the putamen and compromised contribution of the putamen to the default mode network. Results were corrected for multiple comparisons at the cluster level with primary voxel-wise threshold p < 0.005 for the salience network contribution, but liberal primary threshold p < 0.05 was used in other group comparisons. If replicated in larger studies, these findings may help unify and extend current hypotheses on dopaminergic dysfunction, salience processing and pathogenesis of delusions.

    Parental substance use is a major risk factor for child development, heightening the risk of drug problems in adolescence and young adulthood, and exposing offspring to several types of traumatic events. First, prenatal drug exposure can be considered a form of trauma itself, with subtle but long-lasting sequelae at the neuro-behavioral level. Second, parents' addiction often entails a childrearing environment characterized by poor parenting skills, disadvantaged contexts and adverse childhood experiences (ACEs), leading to dysfunctional outcomes. Young adults born from/raised by parents with drug problems and diagnosed with a Substance Used Disorder (SUD) themselves might display a particularly severe condition in terms of cognitive deficits and impaired personality function. This preliminary study aims to investigate the role of early exposure to drugs as a traumatic event, capable of affecting the psychological status of young drug addicts. In particular, it intends to examine the neuropsychological functioning and personality profile of young adults with severe SUDs who were exposed to drugs early in their family context. The research involved three groups, each consisting of 15 young adults (aged 18–24): a group of inpatients diagnosed with SUDs and exposed to drugs early, a comparison group of non-exposed inpatients and a group of non-exposed youth without SUDs. A neuropsychological battery (Esame Neuropsicologico Breve-2), an assessment procedure for personality disorders (Shedler-Westen Assessment Procedure-200) and the Symptom CheckList-90-Revised were administered. According to present preliminary results, young drug addicts exposed to drugs during their developmental age were characterized by elevated rates of neuropsychological impairments, especially at the expense of attentive and executive functions (EF); personality disorders were also common but did not differentiate them from non-exposed youth with SUDs.

    Full Text Available Proprotein convertase subtilisin/kexin type 9 (encoded by PCSK9 plays a well-known role in the regulation of low-density lipoprotein (LDL receptors, and an inhibitor of this enzyme is a promising new therapeutic for hyperlipidemia. Recently, animal and human studies also implicate PCSK9 genetic variation in the regulation of blood pressure. The goal of this study was to examine if common and rare polymorphisms in PCSK9 are associated with blood pressure in an African-American population at high risk for cardiovascular disease. Using genomic data assayed on the Affymetrix 6.0 array (n = 1199 and the Illumina HumanExome Beadchip (n = 1966 from the Hypertension Genetic Epidemiology Network (HyperGEN, we tested the association of PCSK9 polymorphisms with blood pressure. We used linear mixed models and the sequence kernel association test (SKAT to assess the association of 31 common and 19 rare variants with blood pressure. The models were adjusted for age, sex, center, smoking status, principal components for ancestry and diabetes as fixed effects and family as a random effect. The results showed a marginally significant effect of two genome-wide association study (GWAS single-nucleotide polymorphisms (SNPs (rs12048828: β = 1.8, P = 0.05 and rs9730100: β = 1.0, P = 0.05 with diastolic blood pressure (DBP; however these results were not significant after correction for multiple testing. Rare variants were cumulatively associated with DBP (P = 0.04, an effect that was strengthened by restriction to nonsynonymous or stop-gain SNPs (P = 0.02. While gene-based results for DBP did not replicate (P = 0.36, we found an association with SBP (P = 0.04 in the Reasons for Geographic And Racial Differences in Stroke study (REGARDS. The findings here suggest rare variants in PCSK9 may influence blood pressure among African Americans, laying the ground work for further validation studies.

    Full Text Available The aim of this preliminary study was to evaluate the effect of low-dose oral vitamin D in combination with current disease-modifying therapy on the prevention of progression of relapsing-remitting multiple sclerosis (RRMS. A phase II double-blind placebo-controlled randomized clinical trial conducted between October 2007 and October 2008 included 50 patients with confirmed RRMS aged 25 to 57 years and normal serum 25-hydroxyvitamin D. They were randomly allocated to receive 12 months of treatment with either escalating calcitriol doses up to 0.5 μg/day or placebo combined with disease-modifying therapy. Response to treatment was assessed at eight-week intervals. In both groups, the mean relapse rate decreased significantly (P<0.001. In the 25 patients treated with placebo, the mean (SD Expanded Disability Status Scale (EDSS increased from 1.70 (1.21 at baseline to 1.94 (1.41 at the end of study period (P<0.01. Average EDSS and relapse rate at the end of trial did not differ between groups. Adding low-dose vitamin D to routine disease-modifying therapy had no significant effect on the EDSS score or relapse rate. A larger phase III multicenter study of vitamin D in RRMS is warranted to more assess the efficacy of this intervention.

    Leukocyte telomere length (LTL) is a biomarker of cellular aging affected by chronic stress. The relationship of LTL to the stress hormones, cortisol and catecholamines, is unclear, as are possible differences between healthy controls (HC) and individuals with Major Depressive Disorder (MDD). This small pilot study is the first to examine the relationship between cortisol, catecholamines and LTL specifically in un-medicated MDD in comparison with HC. Participants included 16 un-medicated MDD subjects and 15 HC for assay of LTL, 12-hour overnight urinary free cortisol and catecholamine levels. LTL, cortisol and catecholamine levels did not significantly differ between groups. In HC, a hierarchical regression analysis indicated that higher levels of cortisol were correlated with shorter LTL (p=0.003) above and beyond age and sex. Higher catecholamine levels were nearly-significant with shorter LTL (p=0.055). Neither hormone was correlated with shorter LTL in MDD (p's>0.28). To assess a possible cumulative effect of stress hormone activation, a summary score was calculated for each subject based on the number of stress hormone levels above the median for that group (HC or MDD). A significant inverse graded relationship was observed between LTL and the number of activated systems in HC (p=0.001), but not in MDD (p=0.96). This pilot study provides preliminary evidence that stress hormone levels, especially cortisol, are inversely related to LTL in HC, but not in un-medicated MDD. Clarification of these relationships in larger samples could aid in understanding differential mechanisms underlying stress-related cellular aging in healthy and depressed populations.

    Full Text Available Abstract Background Few measures of health related quality of life exist for use with preschool aged children. The objective of this study was to assess reliability and validity of a new multidimensional generic measure of health-related quality of life developed for use with preschool children. Methods Cross-sectional survey sent to parents as their child turned 3 1/2 years of age. The setting was the province of British Columbia, Canada. Patients included all babies admitted to tertiary level neonatal intensive care units (NICU at birth over a 16-month period, and a consecutive sample of healthy babies. The main outcome measure was a new full-length questionnaire consisting of 3 global items and 10 multi-item scales constructed to measure the physical and emotional well-being of toddlers and their families. Results The response rate was 67.9%. 91% (NICU and 84% (healthy baby of items correlated with their own domain above the recommended standard (0.40. 97% (NICU and 87% (healthy baby of items correlated more highly (≥ 2 S.E. with their hypothesized scale than with other scales. Cronbach's alpha coefficients varied between .80 and .96. Intra-class correlation coefficients were above .70. Correlations between scales in the new measure and other instruments were moderate to large, and were stronger than between non-related domains. Statistically significant differences in scale scores were observed between the NICU and healthy baby samples, as well as between those diagnosed with a health problem requiring medical attention in the past year versus those with no health problems. Conclusions Preliminary results indicate the new measure demonstrates acceptable reliability and construct validity in a sample of children requiring NICU care and a sample of healthy children. However, further development work is warranted.

    Increased chromosomal breakage was found in 12 patients with DSM-IV Tourette syndrome (TS) as compared with 10 non-TS control individuals with respect to untreated, modified RPM1-, and BrdU treated lymphocyte cultures (P < 0.001 in each category). A hypothesis is proposed that a major TS gene is probably connected to genetic instability, and associated chromosomal marker sites may be indicative of the localization of secondary genes whose altered expression could be responsible for associated comorbid conditions. This concept implies that genes influencing higher brain functions may be situated at or near highly recombigenic areas allowing enhanced amplification, duplication and recombination following chromosomal strand breakage. Further studies on a larger sample size are required to confirm the findings relating to chromosomal breakage and to analyze the possible implications for a paradigmatic shift in linkage strategy for complex disorders by focusing on areas at or near unstable chromosomal marker sites. 32 refs., 1 tab.

    The ability to quickly find, easily use and effortlessly integrate data from a variety of sources is a grand challenge in Earth sciences, one around which entire research programs have been built. A myriad of approaches to tackling components of this challenge have been demonstrated, often with some success. Yet finding, assessing, accessing, using and integrating data remains a major challenge for many researchers. A technology that has shown promise in nearly every aspect of the challenge is semantics. Semantics has been shown to improve data discovery, facilitate assessment of a data set, and through adoption of the W3C's Linked Data Platform to have improved data integration and use at least for data amenable to that paradigm. Yet the creation of semantic resources has been slow. Why? Amongst a plethora of other reasons, it is because semantic expertise is rare in the Earth and Space sciences; the creation of semantic resources for even a single discipline is labor intensive and requires agreement within the discipline; best practices, methods and tools for supporting the creation and maintenance of the resources generated are in flux; and the human and financial capital needed are rarely available in the Earth sciences. However, other fields, such as biomedicine, have made considerable progress in these areas. The NSF-funded ClearEarth project is adapting the methods and tools from these communities for the Earth sciences in the expectation that doing so will enhance progress and the rate at which the needed semantic resources are created. We discuss progress and results to date, lessons learned from this adaptation process, and describe our upcoming efforts to extend this knowledge to the next generation of Earth and data scientists.

    Examine whether acceptance and commitment additive therapy is effective in reducing the experience of sensory pain, disability, and affective distress because of chronic headache in a sample of outpatient Iranian females. Chronic headaches have a striking impact on sufferers in terms of pain, disability, and affective distress. Although several Acceptance and Commitment Therapy outcome studies for chronic pain have been conducted, their findings cannot be completely generalized to chronic headaches because headache-related treatment outcome studies have a different emphasis in both provision and outcomes. Moreover, the possible role of Iranian social and cultural contexts and of gender-consistent issues involved in Acceptance and Commitment Therapy outcomes deserve consideration. This study used a randomized pretest-post-test control group design. The sample was selected from consecutive female outpatients with chronic headache, attending and/or referred to a headache clinic in a governmental hospital from April 2011 to June 2011. In total, 80 female outpatients were interviewed, and after implementing inclusion/exclusion criteria, thirty females were considered eligible to participate in the study. Half (n = 15) were randomly selected to participate in the treatment group. Four participants of this group failed to complete the treatment sessions (n = 11). The Acceptance and Commitment Therapy group received the medical treatment as usual and 8 sessions of Acceptance and Commitment Therapy. The other half (n = 15) served as the control group that received only medical treatment as usual. The short form of McGill pain questionnaire, the migraine disability assessment scale, and the trait subscale of the state-trait anxiety inventory were administered, which operationalized 3 dimensions of impact of chronic headache, sensory pain, disability, and emotional distress, respectively, to explore the impact of recurrent headache episodes.

    Full Text Available Beta Glucan food supplements have been reported to be of benefit in diabetes and hyperlipidemia. We report a pilot study of the effects of Nichi Glucan, 1, 3-1, 6 Beta Glucan food supplement, in lowering the blood glucose and lipid levels in three patients with noninsulin-dependent diabetes mellitus (NIDDM from India. These patients had increased blood glucose and lipid levels inspite of routine antidiabetic and lipid level lowering medications. Each of the participants took 1.5 g of Nichi Glucan per day with food for two months along with their routine medications. The relevant parameters to assess glycemic status and lipid levels were calculated at the baseline and at the end of two months. After two months of continuous consumption, in one patient, the HbA1c decreased from 9.1% to 7.8%, and the glycemic target of HbA1c <6.5% laid down by the International Diabetes Federation was reached in two patients. Lipid levels also decreased significantly. Based on our findings, Nichi Glucan food supplement can be considered along with routine medications in patients with Type II diabetes with hyperlipidemia. Further studies are needed to validate the results.

    The same language symptom might arise at different functional loci in people with aphasia. Therefore, it is plausible that different therapeutic interventions should be adopted to approach the same difficulties in different patients. Although this point of view is still widely accepted, recently the focus has shifted from the functional locus of a rehabilitative intervention to the mechanisms of action underlying the relearning process. We maintain that both aspects should be taken into account when programming a rehabilitative intervention; furthermore, investigating relearning mechanisms might shed new light on the functional architecture of the disrupted processes. Here, we investigated, in a single case study, whether classical conditioning was a suitable relearning paradigm for targeting word-finding difficulties in pure anomia, that is in a patient with an impairment in accessing intact output lexical representations from a spared semantic system. Using a word-repetition task on picture presentation, we contrasted a condition in which the stimulus onset asynchrony between word and picture stimuli was well suited to produce classical conditioning with a condition in which repetition training could not benefit from this learning mechanism. Only classical conditioning training exerted a significant, long-lasting effect on our patient's naming skill. Tentative implications of our results for the functional architecture of single-word processing are discussed. © 2015 The British Psychological Society.

    Among the serious mental health problems that may be associated with being a refugee is suicidal behavior. This study aimed to assess the prevalence and correlates of suicidal ideation among African refugees in Oru-Ijebu Nigeria. Suicidal ideation was assessed using appropriate section in the Mini-International Neuropsychiatric Interview while the brief version of the WHO Quality of Life was used to assess quality of life as a clinical variable. Study involved 444 refugees and 527 non-refugee member of host community. Result showed that the prevalence of suicidal ideation was significantly higher among the refugees than the non-refugee comparison group (27.3% vs. 17.3%; prefugees compared with their non-refugee members of same community. Quality of life was the only factor independently associated with suicidal ideations among refugees. In conclusion, the study shows that the prevalence of suicidal ideation is significantly higher among the refugees than the non-refugee members of the host community and calls for innovative ways of extending mental health services to refugees at the study site.

    Boston's more than 500 automotive shops, located primarily in low-income communities of color, are a source both of well-paying jobs and of potential hazardous exposures to employees and residents. The Safe Shops Project works to reduce occupational and environmental health hazards without having to close these businesses. Combining inspections, in-shop trainings, outreach, and technical/financial assistance, it brings shops into compliance with laws and promotes use of safer practices and alternative products. After 18 months, 254 workers at 61 of 124 participating shops had received training. Surveys showed improved worker knowledge: Pre-training, 24.2 percent of the worker survey respondents stated that they knew what an MSDS was, and post-training, 75 percent stated that they knew. The surveys also found improvement in work practices: Pre-training, 48 percent of workers indicated that they used safety goggles in their work, while post-training, 70 percent indicated proper use of safety goggles. The results also showed shops investing in capital improvements such as replacement of PCE-based brake cleaners with aqueous cleaners. The Safe Shops Project has a successfully modeled application of the 10-essential-services framework to the building of public health capacity and community collaboration, and this model can be adapted to other locations and industries.

    -based surveillance for suspected DILI in Delaware yielded an incidence of 2.7 cases per 100,000 adults in 2014; this is the first prospective estimate of DILI for the USA. Because surveillance was limited to subspecialists, the actual incidence of DILI is likely to be higher. These findings provide a benchmark statistic for the epidemiology of DILI in the United States, to be refined with expansion of the surveillance period.

    Full Text Available Abstract Background Within the UK, injecting in the femoral vein (FV, often called 'groin injecting', is a serious cause of risk and harm. This study aimed to use ultrasound scanning as a means to engage groin injectors (GIs, examine their femoral injecting sites and assess their venous health, with the intention of developing improved responses. Methods Between September 2006 and March 2009, GIs attending a network of community drug treatment centres in South East England were invited to attend an ultrasound 'health-check' clinic. This paper provides a narrative account of the scanning procedure and operation of the service, with descriptive statistical analysis of GIs who attended. The analysis uses a structured, specially-developed clinical data set that incorporates a categorisation for the severity of FV damage. Case studies using ultrasound images and a link to a video are provided to illustrate the range of presentations encountered and the categorisations used for severity. Results A total of 160 groin scans (76 bilateral and 8 unilateral were performed in 84 GIs. The majority were men (69.0% and the mean age of the sample was 36.8 years. The mean duration of drug use and injecting drug use was 19.7 years and 13.8 years, respectively. FV damage at the injecting site in the right groin was graded as minimal in 20 patients (25%, moderate in 27 (33.8%, severe in 16 (20.0% and very-severe in 17 (21.3%. Corresponding figures for left FV were 24 (30.0%, 22 (27.5%, 18 (22.5% and 16 (20.0%. Wide variation was observed in the time to the development of these grades of FV damage. Conclusions Modern, portable ultrasound scanners make it possible to examine the venous health of GIs in community treatment settings. Ultrasound scanning identified extensive FV damage, much hitherto-unrecognised in this population. These findings should further alert clinicians, policy-makers and patients to the urgent need for effective harm reduction responses to GI

    A 1H nuclear magnetic resonance (1H NMR) method for the determination of gamma-hydroxybutyric acid (GHB) and gamma-hydroxybutyrolactone (GBL) in human serum and urine using spiked samples has been developed. The method gives linear responses (correlation coefficients of 0.99 or greater) over the concentration range 0.01 mg/mL to 4.0 mg/mL in urine and 0.3 mg/mL to 2.0 mg/mL in serum. No sample pretreatment is required. Studies of the chemical interconversion of GBL and GHB showed hydrolysis of GBL to be rapid at pH 11.54, slower and less complete (30% hydrolysis) at pH 2.54 and slowest at pH 7.0, reaching 30% hydrolysis in about 40 days. No esterification of GHB was observed at any pH.

    Sexual desire and arousal difficulties are often correlated in women. However, no studies have examined characteristics of women with clinically diagnosed hypoactive sexual desire disorder (HSDD) that increase the likelihood of co-occurring arousal difficulties. The authors examined combined HSDD and arousal/ lubrication problems using baseline cross-sectional data from the HSDD Registry for Women. Their analyses were restricted to women who could be classified with certainty as having arousal or lubrication difficulties by the Female Sexual Function Index (requiring sexually activity in the past 4 weeks). Results showed that among 426 premenopausal women with HSDD, 50.2% had arousal problems, 42.5% lubrication problems, 39.0% combination, and 46.2% neither. Among 174 postmenopausal women, prevalence percentages were 58.0% arousal, 56.9% lubrication, 49.4% combined, and 34.5% neither. The strongest predictor of combined arousal/lubrication problems was self-reported severity of HSDD. Among premenopausal women, race/ethnicity, depression, and lower relationship happiness were also associated with combined arousal/lubrication problems. Among postmenopausal women, surgical menopause and use of selective serotonin reuptake inhibitors were positively associated with arousal problems. Arousal and lubrication problems were present in approximately half of this subsample of HSDD Registry participants, with distinctions in prevalence and predictors by menopausal status and type of arousal difficulty (arousal vs. lubrication).

We explored global and regional brain volumes in a cross-sectional and follow-up study on adolescents affected by AN. Eleven adolescents with AN underwent a voxel-based morphometry study at time of diagnosis and immediately after weight recovery. Data were compared to volumes carried out in eight healthy, age and sex matched controls. Subjects with AN showed increased cerebrospinal fluid volumes and decreased white and gray matter volumes, when compared to controls. Moreover, significant regional gray matter decrease in insular cortex and cerebellum was found at time of diagnosis. No regional white matter decrease was found between samples and controls. Correlations between psychological evaluation and insular volumes were explored. After weight recovery gray matter volumes normalized while reduced global white matter volumes persisted.

    Exercise effectiveness is related to adherence, compliance and drop-out. The aim of this study is to investigate if exercise-induced pain and health status are related to these outcomes during two exercise programs in knee osteoarthritis patients. Symptomatic knee osteoarthritis patients were randomly allocated to a walking or strengthening program (N=19/group). At baseline, patients were categorized according to their health status. Exercise adherence and compliance were calculated and drop-out rate was registered. For exercise-induced pain, patients rated their pain on an 11-point numeric rating scale (NRS) before and after each training session. Before each session the maximal perceived pain of the last 24h (NRSmax24) was assessed. Patients rated their global self-perceived effect (GPE) on a 7-point ordinal scale after the intervention period. 53% of the participants felt they improved after the program, 6 patients dropped out. The mean adherence and compliance rates were higher than .83 in both groups. Worse health and higher exercise-induced pain were seen in drop-outs. NRSmax24 during the first 3 weeks did not significantly increase compared to baseline, but correlated negatively with adherence during the home sessions (-.56, pdrop-out show a worse health condition and higher exercise-induced pain levels compared to patients that retained the program.

    The aim of this study was to assess the usefulness of selective α1-blockers in children with neurogenic urinary tract dysfunctions and increased leak point pressure (LPP). 14 children from age 6 to 16 years with neurogenic urinary tract dysfunctions (neurogenic bladder) and LPP > 40 cm H₂O were enrolled in the study. All patients received a selective α1-blocker (doxazosin) for 6-8 weeks with an initial dosage of 0.03 mg/kg. During the observation period the continuation of oral anticholinergics, Clean Intermittent Catheterization (CIC), observation of "urinary dryness" and urinary incontinence periods were recommended. Patients were scheduled for a follow-up visit and urodynamic investigation after 6-8 weeks after the doxazosin therapy was started. In 4 patients, urine leakage occurred at lower pressures; in 9 patients, no significant changes in urine leak point pressures were detected; in 3 patients, there was a significant increase in the bladder capacity; in one patient, deterioration in continence was noted. The differences both in LPP and LPV before and after the treatment were not statistically significant. Our observations are consistent with the conclusions from other studies and showed no evident efficacy of doxazosin in children with neurogenic bladder.

    To investigate associations between imaging features and mutational status of clear cell renal cell carcinoma (ccRCC). This multi-institutional, multi-reader study included 103 patients (77 men; median age 59 years, range 34-79) with ccRCC examined with CT in 81 patients, MRI in 19, and both CT and MRI in three; images were downloaded from The Cancer Imaging Archive, an NCI-funded project for genome-mapping and analyses. Imaging features [size (mm), margin (well-defined or ill-defined), composition (solid or cystic), necrosis (for solid tumors: 0%, 1%-33%, 34%-66% or >66%), growth pattern (endophytic, <50% exophytic, or ≥50% exophytic), and calcification (present, absent, or indeterminate)] were reviewed independently by three readers blinded to mutational data. The association of imaging features with mutational status (VHL, BAP1, PBRM1, SETD2, KDM5C, and MUC4) was assessed. Median tumor size was 49 mm (range 14-162 mm), 73 (71%) tumors had well-defined margins, 98 (95%) tumors were solid, 95 (92%) showed presence of necrosis, 46 (45%) had ≥50% exophytic component, and 18 (19.8%) had calcification. VHL (n = 52) and PBRM1 (n = 24) were the most common mutations. BAP1 mutation was associated with ill-defined margin and presence of calcification (p = 0.02 and 0.002, respectively, Pearson's χ (2) test); MUC4 mutation was associated with an exophytic growth pattern (p = 0.002, Mann-Whitney U test). BAP1 mutation was associated with ill-defined tumor margins and presence of calcification; MUC4 mutation was associated with exophytic growth. Given the known prognostic implications of BAP1 and MUC4 mutations, these results support using radiogenomics to aid in prognostication and management.

    This study aimed to assess the feasibility of cardiac global function evaluation during a whole-chest multi-slice CT (MSCT) acquisition in patients referred for suspicion of pulmonary embolism (PE), and to compare the results with planar equilibrium radionuclide ventriculography (ERNA). Ten consecutive haemodynamically stable patients (six female, four male; mean age 69.7 years; heart rate 65-99 bpm) with suspicion of PE underwent an MSCT and ERNA within a 6 h period. CT acquisition was performed after contrast medium injection by using 16 x 1.5 mm collimation and retrospective ECG gating. Left ventricular (LVEF) and right ventricular (RVEF) ejection fractions were calculated using dedicated three-dimensional software. Relationships between measurements obtained with MSCT and ERNA were assessed using linear regression analysis and reliability of MSCT was assessed with intra-class correlation coefficient. Bland-Altman analysis was performed to calculate limits of agreement between MSCT and ERNA. MSCT was performed successfully in ten patients with a mean acquisition time of 16.5{+-}2.8 s. Functional cardiac evaluation was possible on CT for all patients except for one due to poor opacification of right ventricle. Linear regression analysis showed a good correlation between MSCT and ERNA for the LVEF (R=0.91) and the RVEF (R=0.89) measurements. Intra-class correlation was superior for LVEF (0.92) than for the RVEF (0.68). Bland-Altman plots demonstrated that MSCT substantially overestimated the ERNA RVEF. Morphological CT data demonstrated PE in four of ten of patients and alternative diagnoses in five of ten patients. Our study reveals that MSCT with retrospective ECG gating may provide in one modality a morphological and a functional cardiopulmonary evaluation. Comparison with ERNA demonstrated a good correlation for both ventricular ejection fractions. (orig.)

Bland-Altman analysis was performed to calculate limits of agreement between MSCT and ERNA. MSCT was performed successfully in ten patients with a mean acquisition time of 16.5+/-2.8 s. Functional cardiac evaluation was possible on CT for all patients except for one due to poor opacification of right ventricle. Linear regression analysis showed a good correlation between MSCT and ERNA for the LVEF (R=0.91) and the RVEF (R=0.89) measurements. Intra-class correlation was superior for LVEF (0.92) than for the RVEF (0.68). Bland-Altman plots demonstrated that MSCT substantially overestimated the ERNA RVEF. Morphological CT data demonstrated PE in four of ten of patients and alternative diagnoses in five of ten patients. Our study reveals that MSCT with retrospective ECG gating may provide in one modality a morphological and a functional cardiopulmonary evaluation. Comparison with ERNA demonstrated a good correlation for both ventricular ejection fractions.

    Full Text Available This article presents results of ongoing research into personal networks in São Paulo, exploring their relationships with poverty and urban segregation. We present the results of networks of 89 poor individuals who live in three different segregation situations in the city. The article stats by describing and analyzing the main characteristics of personal networks of sociability, highlighting aspects such as their size, cohesion and diversity, among others. Furgher, we investigate the main determinants of these networks, especially their relationship with urban segregation, understood as separation between social groups in the city, and specific forms of sociability. Contrary to much of the literature which takes into account only segregation of individual attributes in the urban space (race, ethnicity, socioeconomic level etc., this investigation tests the importance both of networks and segregation in the reproduction of poverty situations.

    要求原告花費額外資源去釋明本案勝訴可能性以外之其他因素事實。 In eBay v. MercExchange (2006, the U.S. Supreme Court held that courts must apply the traditional four-factor test for injunctive relief in every case. These “principles of equity” required courts to employ the traditional four-factor test under which the plaintiff must demonstrate (1 a likelihood of success of the merits; (2 the existence of irreparable harm; (3 that the balance of hardships tilts in favor of injunctive relief; and (4 that granting an injunction would not harm the public interest. But when assessing whether a particular instance of trademark infringement resulted in “irreparable harm” U.S. federal courts almost uniformly presumed such irreparable harm upon a finding of likelihood of confusion. In fact, the eBay rules should not be used to eviscerate the normal presumption of irreparable harm that attaches upon a showing of liability in trademark cases. In our country when granting or denying preliminary injunction of trademark infringement cases, the plaintiff often provides a preliminary showing with regard to the existence of legal relation and trademark infringement documentary evidence, not actively providing the existence of irreparable harm, that the balance of hardships tilts in favor of injunctive relief and that an injunction is in the public interest. The court reviewing an application for preliminary injunction deliberates on the likelihood of success on the merits as the most important consideration. Compared with patent and copyright cases of the discretion of the preliminary injunction, the court mainly deliberates on the likelihood of success and the existence of irreparable harm as the most important factor. It is clear intellectual property cases, especially trademark cases on the set of preliminary injunction claim, do not require the plaintiff to take the burden of all factors of trial discretion in Taiwan. Because these harms to

    In January of 2011, the owners of property located in the southwest portion of the Weyburn-Midale Unit in Saskatchewan, Canada, alleged that CO2 injected as part of the Weyburn-Midale CO2 Monitoring and Storage Project was leaking from their property. Prior to the property owners' allegations, the International Performance Assessment Centre for Geologic Storage of Carbon Dioxide (IPAC-CO2) had initiated development of an incident response protocol to be implemented when allegations arose of unintentional releases of anthropogenic CO2 from carbon capture and storage projects. IPAC-CO2 implemented this protocol to determine if CO2 concentrations as high as 11% result from an unintentional release of anthropogenic CO2 or if they form naturally from microbial CO2 production in the organic-rich wet environment that characterizes the property. This paper presents preliminary findings resulting from implementation of the IPAC-CO2 incident response protocol. Particular attention is paid to the results of both soil-gas and noble gas analyses.

    Full Text Available The Congo Clawless Otter (Aonyx congicus, is a little-known otter species that inhabits central African rivers and swamps. We report on the results of 3 field expeditions into the Dji Dji River, (Ivindo National Park, Gabon of varying length (3 days to 6 weeks to collect preliminary observations on this species, the sympatric spot-necked otter (Lutra maculicollis, and the fish community of the Dji Dji River. We also surveyed local people (primarily artisanal fishermen in the Makokou area of Ivindo National Park about their knowledge of otter species and human/wildlife conflicts in the area. Sightings of otters in 2010 indicated both otter species to be common on the Dji Dji River. Fish sampling in 2011 indicated high abundance but low diversity of fishes in this blackwater river. Feeding observations of a solitary animal on the Dji Dji and a family of 3 on the Ivindo River indicate a high dependence on large earthworms (Annelidae captured near the river’s edge. With a severe drought in 2011 affecting the Dji Dji River level, we found fewer otters compared to 2010 observations and no families with young. We speculate on the possibility of seasonal downstream movements, which could affect conservation of the species in the region.

    Full Text Available When Su Cleyle and I first decided to start Evidence Based Library and Information Practice, one of the things we agreed upon immediately was that the journal be open access. We knew that a major obstacle to librarians using the research literature was that they did not have access to the research literature. Although Su and I are both academic librarians who can access a wide variety of library and information literature from our institutions, we belong to a profession where not everyone has equal access to the research in our field. Without such access to our own body of literature, how can we ever hope for practitioners to use research evidence in their decision making? It would have been contradictory to the principles of evidence based library and information practice to do otherwise.One of the specific groups we thought could use such an open access venue for discovering research literature was school librarians. School librarians are often isolated and lacking access to the research literature that may help them prove to stakeholders the importance of their libraries and their role within schools. Certainly, school libraries have been in decline and the use of evidence to show value is needed. As Ken Haycock noted in his 2003 report, The Crisis in Canada’s School Libraries: The Case for Reform and Reinvestment, “Across the country, teacher-librarians are losing their jobs or being reassigned. Collections are becoming depleted owing to budget cuts. Some principals believe that in the age of the Internet and the classroom workstation, the school library is an artifact” (9. Within this context, school librarians are looking to our research literature for evidence of the impact that school library programs have on learning outcomes and student success. They are integrating that evidence into their practice, and reflecting upon what can be improved locally. They are focusing on students and showing the impact of school libraries and

    In the second half of the 19th century, Jean-Martin Charcot (1825-1893) became famous for the quality of his teaching and his innovative neurological discoveries, bringing many French and foreign students to Paris. A hunger for recognition, together with progressive and anticlerical ideals, led Charcot to invite writers, journalists, and politicians to his lessons, during which he presented the results of his work on hysteria. These events became public performances, for which physicians and patients were transformed into actors. Major newspapers ran accounts of these consultations, more like theatrical shows in some respects. The resultant enthusiasm prompted other physicians in Paris and throughout France to try and imitate them. We will compare the form and substance of Charcot's lessons with those given by Jules-Bernard Luys (1828-1897), Victor Dumontpallier (1826-1899), Ambroise-Auguste Liébault (1823-1904), Hippolyte Bernheim (1840-1919), Joseph Grasset (1849-1918), and Albert Pitres (1848-1928). We will also note their impact on contemporary cinema and theatre.

    its high spatial and spectral resolution, it was possible to zoom into the very heart of this very massive star. In this innermost region, the observations are dominated by the extremely dense stellar wind that totally obscures the underlying central star. The AMBER observations show that this dense stellar wind is not spherically symmetric, but exhibits a clearly elongated structure. Overall, the AMBER observations confirm that the extremely high mass loss of Eta Carinae's massive central star is non-spherical and much stronger along the poles than in the equatorial plane. This is in agreement with theoretical models that predict such an enhanced polar mass-loss in the case of rapidly rotating stars. ESO PR Photo 06c/07 ESO PR Photo 06c/07 RS Ophiuchi in Outburst Several papers from this special feature focus on the later stages in a star's life. One looks at the binary system Gamma 2 Velorum, which contains the closest example of a star known as a Wolf-Rayet. A single AMBER observation allowed the astronomers to separate the spectra of the two components, offering new insights in the modeling of Wolf-Rayet stars, but made it also possible to measure the separation between the two stars. This led to a new determination of the distance of the system, showing that previous estimates were incorrect. The observations also revealed information on the region where the winds from the two stars collide. The famous binary system RS Ophiuchi, an example of a recurrent nova, was observed just 5 days after it was discovered to be in outburst on 12 February 2006, an event that has been expected for 21 years. AMBER was able to detect the extension of the expanding nova emission. These observations show a complex geometry and kinematics, far from the simple interpretation of a spherical fireball in extension. AMBER has detected a high velocity jet probably perpendicular to the orbital plane of the binary system, and allowed a precise and careful study of the wind and the shockwave

    The preliminary breakdown phase of a negative cloud-to-ground lightning flash was observed in detail. Observations were made with a Photron SA1.1 high-speed video camera operating at 9,000 frames per second, fast optical sensors, a flat-plate electric field antenna covering the SLF to MF band, and VHF and UHF radio receivers with bandwidths of 20 MHz. Bright stepwise extensions of a negative leader were observed at an altitude of 8 km during the first few milliseconds of the flash, and were coincident with bipolar electric field pulses called 'characteristic pulses'. The 2-D step lengths of the preliminary processes were in excess of 100 meters, with some 2-D step lengths in excess of 200 meters. Smaller and shorter unipolar electric field pulses were superposed onto the bipolar electric field pulses, and were coincident with VHF and UHF radio pulses. After a few milliseconds, the emerging negative stepped leader system showed a marked decrease in luminosity, step length, and propagation velocity. Details of these events will be discussed, including the possibility that the preliminary breakdown phase consists not of a single developing lightning leader system, but of multiple smaller lightning leader systems that eventually join together into a single system.

    2007-02-15

    Purpose: To evaluate the radiological, ultrasonographic, and magnetic resonance imaging (MRI) findings of idiopathic granulomatous mastitis. Material and Methods: Between April 2002 and June 2005, the mammography, ultrasound, color Doppler ultrasound, non enhanced MR, and dynamic MR findings of nine patients with the preliminary clinical diagnosis of malignancy and the final diagnosis of granulomatous mastitis were evaluated. Results: On mammography, asymmetrical focal densities with no distinct margins, ill-defined masses with spiculated contours, and bilateral multiple ill-defined nodules were seen. On ultrasound, in four patients a discrete, heterogenous hypoechoic mass, in two patients multiple abscesses, in one patient bilateral multiple central hypo peripheral hyperechoic lesions, in two patients heterogeneous hypo- and hyperechoic areas together with parenchymal distortion, and in one patient irregular hypoechoic masses with tubular extensions and abscess cavities were seen. Five of the lesions were vascular on color Doppler ultrasound. On MR mammography, the most frequent finding was focal or diffuse asymmetrical signal intensity changes that were hypointense on T1W images and hyperintense on T2W images, without significant mass effect. Nodular lesions were also seen. On dynamic contrast-enhanced mammography, mass-like enhancement, ring-like enhancement, and nodular enhancement were seen. The time-intensity curves differed from patient to patient and from lesion to lesion. Conclusion: The imaging findings of idiopathic granulomatous mastitis have a wide spectrum, and they are inconclusive for differentiating malignant and benign lesions.

    Full Text Available Available genomic data for the toxic, bloom-forming, benthic Ostreopsis spp. are traditionally obtained from isolates rather than from individuals originally present in environmental samples. Samples from the final phase of the first reported Ostreopsis bloom in European North Atlantic waters (Algarve, south coast of Portugal were studied and characterized, using a culture-independent approach. In the first instance, a microscopy-based analysis revealed the intricate complexity of the samples. Then, we evaluated the adequacy of commonly used molecular tools (i.e., primers and nuclear ribosomal markers for the study of Ostreopsis diversity in natural samples. A PCR-based methodology previously developed to identify/detect common Ostreopsis species was tested, including one new combination of existing PCR primers. Two sets of environmental rRNA sequences were obtained, one of them (1052 bp with the newly tested primer set. These latter sequences encompass both the ITS1-5.8S-ITS2 region and the D1/D2 domain of the LSU rRNA gene, leading us to an accurate identification of ITS2. In turn, this allowed us to predict and show for the first time the ITS2 secondary structure of Ostreopsis. With 92 bp in length and a two-helix structure, the ITS2 of this genus revealed to be unique among the dinoflagellates. Both the PCR approach as the phylogenetic analyses allowed to place the Ostreopsis cells observed in the samples within the O. cf. ovata phylospecies’ complex, discarding the presence of O. cf. siamensis. The (phylogenetic results point out a certain level of nucleotide sequence divergence, but were inconclusive in relation to a possible geographic origin of the O. cf. ovata population from the Algarve’s bloom.

    Full Text Available Background/Aim. The major one among the procedures for evaluating changes in the thyroid nodules is fine needle aspiration biopsy (FNAB. Thyroid scintigraphy is commonly used in diagnostic algoritham of nodules. Less than 5% of examined nodules show to be malignant. Scintigraphically, nodules could be classified as functional and nonfunctional. It is estimated that the risk of malignacy in nonfunctional nodules ranges from 8% to 25% and more. Aspiration punction provides 100% specific and positive predictive value. The aim of the study was to establish the distribution of cytological findings in nonfunctioning thyroid nodules. Methods. The prospective study enrolled 112 patients, 104 women and 8 men, submitted to thyroid scintigraphy for known thyroid nodule disorder. Scintigraphy was performed about half an hour after iv administration of 74 MBq of sodium-pertehnetate. A pin hole collimator was used. Scintigrams were visually evaluated, and absence of radiopharmaceutic in a nodule was estimated as nonfunctional one. Such nodules were afterwards subjected to FNAB and material obtained was cytologically analyzed. Results. In our patients nonfunctioning nodules comprised tissue of colloid struma, thyroid cyst, regular thyroid tissue, follicular lesion, oxiphillic lesion, papillary carcinoma tissue and tissue of lymphocytic thyroiditis. The most frequent cytological finding were colloid cysts (52%. A total of 70% were female nodules. Five citological findings were histopathologically analyzed. Conclusion. Cytological finding of nonfunctional nodules determines of the decision on radical therapy, and our preliminary results imply the need of FNAB routine use in nuclear medicine practice.

    Full Text Available Research regarding physician suicide in Taiwan is lacking. Using national physician insurance data from January 1, 2000 to April 30, 2008, the present study aimed to explore the association between physicians' suicide and their characteristics, including age, sex, specialties, area of residence, hospital types, and suicide methods. The majority (53.1–70.6% of suicide cases occurred among physicians in their 40s. More suicides were reported among physicians serving in the community, living in urban areas, and from specialties such as general practice, family practice, psychiatry, and surgery. The leading suicide methods were hanging/suffocation, drowning, jumping from heights, charcoal burning and drug poisoning. In conclusion, physicians committing suicide were likely to be in their 40s, to serve in the community and to live in urban areas. Future efforts should focus on exploring the causes and possible interventions for physician suicide.

    To examine stakeholder perspectives of the Bachelor of Dental Surgery 2012-2013 clinical outplacement programme with Māori Oral Health Providers (MOHPs) and inform the programme's ongoing development. A mixed methods kaupapa Māori action research project. Six North Island MOHPs and the University of Otago Faculty of Dentistry. Online questionnaires were used to conduct a pre- and post-outplacement survey of dental students and a twice-yearly survey of all MOHP-based clinical supervisors. Paper questionnaires were used to survey adult clients and caregivers of child clients that the students treated. Data were analysed descriptively and thematically. 68 (61%) of the 112 eligible students completed the pre- and post-outplacement questionnaires; 31 clinical supervisor questionnaire responses were received representing all six MOHPs; and 426 client and 130 caregiver questionnaire responses were received from five MOHPs. 79% of students felt well prepared for outplacement and 75% indicated that they would consider working for a MOHP in future. Of the clinical supervisors, 93% indicated that the students were adequately prepared for outplacement, and 68%, that they would recommend one or more students for employment. However, 58% associated the outplacements with decreased productivity. More than 97% of adult clients and caregivers of child clients were pleased with the care that the students provided. Recommendations for strengthening the outplacement programme included: increasing communication between the Faculty, MOHPs and students; addressing the financial cost of the programme to the MOHPs; and providing more support for clinical supervisors.

    The Italian Dystonia Registry is a multicenter data collection system that will prospectively assess the phenomenology and natural history of adult-onset dystonia and will serve as a basis for future etiological, pathophysiological and therapeutic studies. In the first 6 months of activity, 20 movement disorders Italian centres have adhered to the registry and 664 patients have been recruited. Baseline historical information from this cohort provides the first general overview of adult-onset dystonia in Italy. The cohort was characterized by a lower education level than the Italian population, and most patients were employed as artisans, builders, farmers, or unskilled workers. The clinical features of our sample confirmed the peculiar characteristics of adult-onset dystonia, i.e. gender preference, peak age at onset in the sixth decade, predominance of cervical dystonia and blepharospasm over the other focal dystonias, and a tendency to spread to adjacent body parts, The sample also confirmed the association between eye symptoms and blepharospasm, whereas no clear association emerged between extracranial injury and dystonia in a body site. Adult-onset dystonia patients and the Italian population shared similar burden of arterial hypertension, type 2 diabetes, coronary heart disease, dyslipidemia, and hypothyroidism, while hyperthyroidism was more frequent in the dystonia population. Geographic stratification of the study population yielded no major difference in the most clinical and phenomenological features of dystonia. Analysis of baseline information from recruited patients indicates that the Italian Dystonia Registry may be a useful tool to capture the real world clinical practice of physicians that visit dystonia patients.

    2009-01-01

    To date, diagnostic quality ultrasound images were obtained aboard the International Space Station (ISS) using the ultrasound of the Human Research Facility (HRF) rack in the Laboratory module. Through the Advanced Diagnostic Ultrasound in Microgravity (ADUM) and the Braslet-M Occlusion Cuffs (BRASLET SDTO) studies, non-expert ultrasound operators aboard the ISS have performed cardiac, thoracic, abdominal, vascular, ocular, and musculoskeletal ultrasound assessments using remote guidance from ground-based ultrasound experts. With exploration class missions to the lunar and Martian surfaces on the horizon, crew medical officers will necessarily need to operate with greater autonomy given communication delays (round trip times of up to 5 seconds for the Moon and 90 minutes for Mars) and longer periods of communication blackouts (due to orbital constraints of communication assets). The SURGE project explored the feasibility and training requirements of having non-expert ultrasound operators perform autonomous ultrasound assessments in a simulated exploration mission outpost. The project aimed to identify experience, training, and human factors requirements for crew medical officers to perform autonomous ultrasonography. All of these aims pertained to the following risks from the NASA Bioastronautics Road Map: 1) Risk 18: Major Illness and Trauna; 2) Risk 20) Ambulatory Care; 3) Risk 22: Medical Informatics, Technologies, and Support Systems; and 4) Risk 23: Medical Skill Training and Maintenance.

    Students with disabilities are commonly excluded from full participation in geoscience programs, and encounter significant barriers when accessing field-learning experiences. In order to increase talent and diversity in the geoscience workforce, more inclusive learning experiences must be developed that will enable all students to complete the requirements of undergraduate degree programs, including fieldwork. We discuss the outcomes of a completely accessible field course developed through the collaborative effort of geoscience education practitioners from the US, Canada and the UK. This unique field workshop has brought together current geoscience academics and students with disabilities to share perspectives on commonly-encountered barriers to learning in the field, and explore methods and techniques for overcoming them. While the student participants had the opportunity to learn about Earth processes while situated in the natural environment, participating geoscience instructors began to identify how to improve the design of field courses, making them fully inclusive of learners with disabilities. The outcomes from this experience will be used to develop guidelines to facilitate future development and delivery of accessible geoscience fieldwork.

  8. STD studies show spermicides protect against Chlamydia.

    Science.gov (United States)

    1986-01-01

    Evidence which suggests that spermicides provide protection against sexually transmitted diseases (STDs) is accumulating. Laboratory tests have repeatedly demonstrated that spermicides are capable of killing the bacteria responsible for several types of STDs, as well as the virus responsible for acquired immunodeficiency syndrome. Recently, studies conducted in Bangkok, Thailand and in New York City suggest that these protective effects are not confined to the laboratory but that they also occur among women who use spermicides in the real world. In the New York City study, Family Health International (FHI), using data collected by Planned Parenthood of New York City, compared STD prevalence rates for women using different contraceptive methods. Women who used spermicides, in comparison with women who used oral contraceptives (OCs), were 20% less likely to have contracted a STD, 30% less likely to have gonorrhea, and 60% less likely to have chlamydia. In the Thai study, conducted jointly by the FHI and the Ministry of Health, women at high risk of STDs were allocated either to a group which was instructed to use a vaginal sponge impregnated with nonoxynol-9 during intercourse or to a control group which received no vaginal contraceptives. All the women were either sterilized or using OCs, IUDs, or injectable contraceptives. Preliminary results suggest that the women who used the vaginal sponges were significantly less likely to contract chlamydia than the control group. In regard to the incidence of gonorrhea, no differences between the 2 groups was detected. In the Thai study methodological problems forced the researchers to redesign the study. In accordance with the new design, the women in the 2 groups will be crossed over after 6 weeks. This will allow the researchers to examine the effect of using or not using a vaginal spermicide on specific individuals. The findings of the 2 studies have special relevance given the increasing prevalence of STDs in many

    1981-06-01

    A large data set consisting of about 1000 normal mode periods, 500 summary travel time observations, 100 normal mode Q values, mass and moment of inertia have been inverted to obtain the radial distribution of elastic properties, Q values and density in the Earth's interior. The data set was supplemented with a special study of 12 years of ISC phase data which yielded an additional 1.75 × 10 6 travel time observations for P and S waves. In order to obtain satisfactory agreement with the entire data set we were required to take into account anelastic dispersion. The introduction of transverse isotropy into the outer 220 km of the mantle was required in order to satisfy the shorter period fundamental toroidal and spheroidal modes. This anisotropy also improved the fit of the larger data set. The horizontal and vertical velocities in the upper mantle differ by 2-4%, both for P and S waves. The mantle below 220 km is not required to be anisotropic. Mantle Rayleigh waves are surprisingly sensitive to compressional velocity in the upper mantle. High S n velocities, low P n velocities and a pronounced low-velocity zone are features of most global inversion models that are suppressed when anisotropy is allowed for in the inversion. The Preliminary Reference Earth Model, PREM, and auxiliary tables showing fits to the data are presented.

    1994-01-15

    To evaluate the characteristic CT findings of neuroblastoma, we studied neuroblastomas. We analysed CT findings of available 25 cases among pathologically proved 51 neuroblastomas from Jan. 1983 to Sept. 1990. The most frequent site of origin is adrenal gland (40%) and the second is retroperitoneum (32%) and the third ismediastinum (16%). Characteristic CT findings are as follows: Calcifications within the tumor is detected in 86% of abdominal neuroblastomas and 50% of mediastinal origin. Hemorrhagic and necrotic changes within the tumor is noted at 86% in the tumor of abdominal origin and 25% in mediastinal neuroblastomas. Contrast enhanced study showed frequently seperated enhanced appearance with/without solid contrast enhancement. Encasements of major great vessels such as aorta and IVC with/without displacement by metastatic lymph nodes or tumor are frequently seen in 90% of abdominal neuroblastomas. Multiple lymphadenopathy are detected in 95% of abdominal neuroblastomas and 25% of mediastinal neuroblastomas. The most common organ or contiguous direct invasion is kidney in 6 cases and the next one is liver but intraspinal canal invasion is also noted in 2 cases. We concluded that diagnosis of neuroblastoma would be easily obtained in masses of pediatric group from recognition of above characteristic findings.

    Objective The purpose of this retrospective study was to investigate the relationship between oral habits and temporomandibular joint (TMJ) bony change of temporomandibular disorder (TMD) patients. Methods One hundred and six TMD patients diagnosed according to Research Diagnostic Criteria (RDC/TMD) were selected. All the patients had undergone cone beam computed tomography (CBCT) imaging of TMJ, and their oral habits had been investigated. The associations between oral habits and TMJ radiographic findings were analysed. Results Among 106 patients, the incidence of bruxism, clenching, chewing on one side and being fond of hard food were high. Preferring to hard food increased the risk of ill -defined cortical bone change. Hobby of hard food increased the risk of bony changes in the anterolateral and posterolateral part of the condyle, as well as in the articular tubercle. Chewing on one side could increase the risk of bony changes in the anteromedial aspect of articular fossa. Conclusion Oral habits of TMD patients were associated with type and position TMJ bony change.%目的 研究颞下颌关节病患者口腔不良习惯与颞下颌关节髁突骨质改变之间的关系.方法 选取诊断为颞下颌关节紊乱病的患者106例,问卷调查患者的口腔不良习惯,并行双侧颞下颌关节锥形束CT成像,分析患者口腔不良习惯与颞下颌关节髁突骨质影像学改变的相关性.结果 106例患者中,口腔不良习惯以偏侧咀嚼、紧咬牙、夜磨牙和喜食硬物较常见.经统计学分析,喜食硬物是出现髁突骨皮质模糊消失型改变的危险因素(P =0.019,OR=2.570).喜食硬物是髁突前外侧(P =0.025,OR =2.298)、髁突后外侧(P =0.023,OR =2.692)及关节结节(P=0.020,OR =3.067)易出现骨质改变的危险因素.偏侧咀嚼习惯则是关节窝前内侧(P=0.013,OR =0.311)易出现骨质改变的危险因素.结论 口腔的不良习惯与颞下颌关节骨质改变的类型及部位有一定相关性.

    Horse rider ability has long been measured using horse performance, competition results and visual observation. Scientific methods of measuring rider ability on the flat are emerging such as measuring position angles and harmony of the horse-rider system. To date no research has quantified rider ability in show jumping. Kinematic analysis and motion sensors have been used in sports other than show jumping to measure the quality of motor control patterns in humans. The aim of this study was to quantify rider ability in show jumping using body-mounted IMUs. Preliminary results indicate that there are clear differences in experienced and novice riders during show jumping.

Tais paradoxos podem ser compreendidos à luz do pensamento do filósofo alemão Friedrich Nietzsche, que, através dos usos de formulações paradoxais, concebia a realidade como um mundo de pura aparência e a verdade como um acréscimo ficcional, como um efeito. A ficção é então tomada, na filosofia de Nietzsche, não em seu aspecto falsificante e desrealizador - como sempre pleiteou nossa tradição metafísica -, mas como condição necessária para que certa espécie de invenção possa operar como verdade. Sendo assim, a própria expressão reality show, através de sua formulação paradoxal, engendra explicitamente um mundo de pura aparência, em que a verdade, a parte reality da proposição, é da ordem do suplemento, daquilo que se acrescenta ficcionalmente - como um adjetivo - a show. O ornamento, nesse caso, passa a ocupar o lugar central, apontando para o efeito produzido: o efeito-de-verdade. Seguindo, então, o pensamento nietzschiano e sua atualização na contemporaneidade, investigaremos de que forma os televisivos “shows de realidade” operam paradoxalmente, em consonância com nossas paradoxais práticas culturais.

    Work at the Los Alamos Scientific Laboratory on the fundamental solution chemistry of the actinides has thus far been confined to preliminary considerations of the problems involved in developing an understanding of the precipitation and dissolution behavior of actinide compounds under environmental conditions. Attempts have been made to calculate solubility as a function of Eh and pH using the appropriate thermodynamic data; results have been presented in terms of contour maps showing lines of constant solubility as a function of Eh and pH. Possible methods of control of the redox potential of rock-groundwater systems by the use of Eh buffers (redox couples) is presented.

  6. Reality shows: uma abordagem psicossocial

    Directory of Open Access Journals (Sweden)

    Marília Pereira Bueno Millan

    Full Text Available Desde os primórdios da civilização, o ser humano mostra necessidade de representar cenicamente seus dramas pessoais e vicissitudes existenciais. O "reality show" é uma das versões pós-modernas da encenação da vida humana. Este artigo, por meio de uma pesquisa bibliográfica, analisa criticamente as relações existentes entre o "reality show" e aspectos psicossociais do comportamento humano. Conclui-se que tais programas televisivos são o retrato da contemporaneidade, ou seja, revelam a morte do sujeito, a fugacidade das experiências vividas, a desvalorização da história e o culto à imagem e à superficialidade. Por meio da sedução do espectador, mobilizam-se aspectos primitivos de seu psiquismo, fazendo com que ele se sinta narcisicamente poderoso e onipotente e se acredite dono do destino dos participantes do programa. Sugerem-se novos estudos que contribuam para a reflexão crítica e maior conscientização.

  7. "Medicine show." Alice in Doctorland.

    1987-01-01

    This is an excerpt from the script of a 1939 play provided to the Institute of Social Medicine and Community Health by the Library of Congress Federal Theater Project Collection at George Mason University Library, Fairfax, Virginia, pages 2-1-8 thru 2-1-14. The Federal Theatre Project (FTP) was part of the New Deal program for the arts 1935-1939. Funded by the Works Progress Administration (WPA) its goal was to employ theater professionals from the relief rolls. A number of FTP plays deal with aspects of medicine and public health. Pageants, puppet shows and documentary plays celebrated progress in medical science while examining social controversies in medical services and the public health movement. "Medicine Show" sharply contrasts technological wonders with social backwardness. The play was rehearsed by the FTP but never opened because funding ended. A revised version ran on Broadway in 1940. The preceding comments are adapted from an excellent, well-illustrated review of five of these plays by Barabara Melosh: "The New Deal's Federal Theatre Project," Medical Heritage, Vol. 2, No. 1 (Jan/Feb 1986), pp. 36-47.

    2012-12-01

    Full Text Available The issue of Corporate Social Disclosure (CSD has been growing remarkably both in business and academic world.  Inevitably, this topic is also exposed in Southeast Asia, a big region that plays important role in global economic issue. Applying a content analysis method, this paper aims to provide preliminary findings in CSD practices throughout the companies‟ annual reports in 2007 and 2008 for countries located in Southeast Asia.  Samples were selected for listed and unlisted various type of industries, based on the information availability internet searching. The sample collection and the subjectivity during the content analysis process are the limitations in conducting this study. In general, the results show that „human resources‟ are the main information disclosed, while in contrast, „energy‟ is the main least issue disclosed in the annual reports.  However, the findings need to be interpreted with considerations since there are limited in samples. Basically, the outcomes support the major prior studies and enhancing the discussion of CSD conducting in developing countries, while at the same time describing some countries which obtained very limited in exposures. To respond the vast increasing issues of CSD practice, this preliminary study has provided a basis to see the role of every country in CSR reporting and how they could support the sustainability development globally.

  10. MR findings of ulegyria

    Magnetic resonance (MR) findings of the brains diagnosed to have ulegyria were reviewed. The reviewed subjects comprised six epileptic children, ranged from 2 to 16 years of age. All patients had convulsion of tonic-clonic type of various severity and had histories of ischemic-hypoxic or hypoglycemic episode in the perinatal or postnatal period. T{sub 1}-weighted images demonstrated the findings precisely reflecting the salient macroscopic features of ulegyria; localized atrophy of the brain with mushroom-shaped cortical gyri with narrow roots and relatively spared wider crowns. T{sub 2}-weighted images showed the areas of hyperintensity in the subcortical and deep white matter subjacent to the atrophic cortex, suggestive of cicatrical gliosis as well as cystic degeneration. The atrophic gyri were seen in the anterior and/or posterior parasagittal arterial border zones bilaterally with minimal asymmetry. Although these findings were nearly pathognomonic to ulegyria, polymicrogyria could mimic it since both are characterized by abnormally diminutive cortical gyri seen in epileptic children. In polymicrogyria, however, affected gyri are uniformly diminutive and not mushroom-shaped, the cortex is rather thickened than atrophic, the underlying white matter shows no focal hyperintensity, subcortical cystic changes are not present, and affected cortex is not restricted to arterial border zones. Even in one of our cases with extensive ulegyria, it was easy to differentiate it from polymicrogyria since parasagittal regions were most severely affected. Although the previous reports on ulegyria have been exclusively based on postmortem pathological examinations or experimental models, its easy recognition on MRI would contribute to further understanding of its clinical significance and mechanisms.

    Sernelius, Bo E

    2009-01-01

    We address several different Casimir experiments where theory and experiment disagree. First out is the classical Casimir force measurement between two metal half spaces; here both in the form of the torsion pendulum experiment by Lamoreaux and in the form of the Casimir pressure measurement between a gold sphere and a gold plate as performed by Decca et al.; theory predicts a large negative thermal correction, absent in the high precision experiments. The third experiment is the measurement of the Casimir force between a metal plate and a laser irradiated semiconductor membrane as performed by Chen et al.; the change in force with laser intensity is larger than predicted by theory. The fourth experiment is the measurement of the Casimir force between an atom and a wall in the form of the measurement by Obrecht et al. of the change in oscillation frequency of a 87 Rb Bose-Einstein condensate trapped to a fused silica wall; the change is smaller than predicted by theory. We show that saturation effects can exp...

    Rogallo, Francis M.; Lowry, John G.; Croom, Delwin R.; Taylor, Robert T.

    1960-01-01

    A preliminary investigation of the aerodynamic and control characteristics of a flexible glider similar to a parachute in construction has been made at the Langley Research Center to evaluate its capabilities as a reentry glider. Preliminary weight estimates of the proposed vehicle indicate that such a structure can be made with extremely low wing loading. Maximum temperatures during the reentry maneuver might be held as low as about 1,500 F. The results of wind-tunnel and free-glide tests show that the glider when constructed of nonporous material performed extremely well at subsonic speeds and could be flown at angles of attack from about 200 to 900. At supersonic speeds the wing showed none of the unfavorable tendencies exhibited by conventional parachutes at these speeds, such as squidding and breathing. Several methods of packing and deploying the glider have been successfully demonstrated. The results of this study indicate that this flexible-lifting-surface concept may provide a lightweight controllable paraglider for manned space vehicles.

  16. An Investigation of the Academic Information Finding and Re-finding Behavior on the Web

    Directory of Open Access Journals (Sweden)

    Hsiao-Tieh Pu

    2014-12-01

    Full Text Available Academic researchers often need and re-use relevant information found after a period of time. This preliminary study used various methods, including experiments, interviews, search log analysis, sequential analysis, and observation to investigate characteristics of academic information finding and re-finding behavior. Overall, the participants in this study entered short queries either in finding or re-finding phases. Comparatively speaking, the participants entered greater number of queries, modified more queries, browsed more web pages, and stayed longer on web pages in the finding phase. On the other hand, in the re-finding phase, they utilized personal information management tools to re-find instead of finding again using search engine, such as checking browsing history; moreover, they tend to input less number of queries and stayed shorter on web pages. In short, the participants interacted more with the retrieval system during the finding phase, while they increased the use of personal information management tools in the re-finding phase. As to the contextual clues used in re-finding phase, the participants used less clues from the target itself, instead, they used indirect clues more often, especially location-related information. Based on the results of sequential analysis, the transition states in the re-finding phase was found to be more complex than those in the finding phase. Web information finding and re-finding behavior is an important and novel area of research. The preliminary results would benefit research on Web information re-finding behavior, and provide useful suggestions for developing personal academic information management systems.

    Neurofibromatosis is an uncommon but certainly not a rare hereditary disorder, probably of neuralcrest origin, involving not only neuroectoderm and mesoderm but also endoderm and characterized by cafe au lait spots and cutaneous and subcutaneous tumors, with secondary mesodermal defects responsible for protean osseous abnormalities and various manifestations in other systems. This paper is a study of confirmed 143 cases of neurofibromatosis collected for past 8 years. In this analysis, special attention was given to the selected 37 cases which showed abnormal findings on radiological examinations. Overall male to female ratio was 1 : 1.3. The most frequent kind of abnormalities was vertebral kyphoscoliosis in 12 cases. Among the more pathognomonic but uncommon abnormalities to neurofibromatosis, we experienced each 2 cases of lambdoid defect, pseudoarthrosis and renovascular hypertension, and 1 cases of sphenoid bone absence.

    In this report, we present computed tomographic findings of colonic trichuriasis. The patient was a 75-year-old man who complained of abdominal pain, and weight loss.Diagnosis was achieved by colonoscopic biopsy. Abdominal computed tomography showed irregular and nodular thickening of the wall of the cecum and ascending colon.Although these findings are nonspecific, they may be one of the findings of trichuriasis. These findings, confirmed by pathologic analysis of the biopsied tissue and KatoKatz parasitological stool flotation technique, revealed adult Trichuris. To our knowledge, this is the first report of colonic trichuriasis indicated by computed tomography.

    Radiographic findings in the sternal abnormalities are often nonspecific, showing appearances from a localized benign lesion to an aggressive lesion as seen with infections and malignant neoplasms. A specific diagnosis of sternal abnormalities can be suggested on the basis of CT and MR characteristics. Familiarity with the presentation and variable appearance of sternal abnormalities may aid the radiologist is suggesting a specific diagnosis. We present among others characteristic radiographic findings of hemangioma, chondrosarcoma, hydatid disease, and SAPHO syndrome. In those cases in which findings are not specific, cross-sectional imaging modalities may help the clinician in their management. (orig.)

    To evaluate the MR findings of brain damage in cerebral palised patients and to correlate it with gestational age and the time of damage. A retrospective analysis was performed in 40 patients who underwent MR scanning for evaluation of brain lesion in clinically diagnosed cerebral palsy. Authors classified the patients into two groups as premature and full-term and compared MR findings of the two groups. Abnormal MR findings were noted in 28 cases (70%). Five out of 6 patients who had been born prematurely showed isolate periventricular white matter lesions. Twenty-three out of 34 patients who had been born at full-term showed abnormal MR findings. Of these 23 patients, migration anomalies in 7 patients, isolate periventricular white matter lesions in 3 patients, and other combined periventricular subcortical white matter and deep gray matter lesions in 14 patients were seen. At least, 10 patients(43%) of full term group showed abnormal MRI findings reflecting intrauterine brain damage and all 5 patients of premature group showed isolate periventricular white matter lesions suggesting immaturity of brain. MRI is thought to be very useful in the assessment of brain damage for the patients with cerebral palsy by recognizing the location of the lesion and estimating the time of damage.

    Recent claims of cultivable ancient bacteria within sealed environments highlight our limited understanding of the mechanisms behind long-term cell survival. It remains unclear how dormancy, a favored explanation for extended cellular persistence, can cope with spontaneous genomic decay over......-term survival of bacteria sealed in frozen conditions for up to one million years. Our results show evidence of bacterial survival in samples up to half a million years in age, making this the oldest independently authenticated DNA to date obtained from viable cells. Additionally, we find strong evidence...... that this long-term survival is closely tied to cellular metabolic activity and DNA repair that over time proves to be superior to dormancy as a mechanism in sustaining bacteria viability....

    The authors analyse the ultrasonographic findings of 10 cases of appendiceal mucocele retrospectively. In a total of 10 cases, 6 cases showed only cystic masses with posterior reinforcement. The remaining 4 cases showed internal echoes in the cystic masses. Differential diagnosis of mucocele from periappendiceal abscess is not possible in ultrasound. The possibility of mucocele should be considered if cystic mass right lower quadrant abdomen is observed in ultrasound.

  2. Preliminary Iron Distribution on Vesta

    Mittlefehldt, David W.; Mittlefehldt, David W.

    2013-01-01

    The distribution of iron on the surface of the asteroid Vesta was investigated using Dawn's Gamma Ray and Neutron Detector (GRaND) [1,2]. Iron varies predictably with rock type for the howardite, eucrite, and diogenite (HED) meteorites, thought to be representative of Vesta. The abundance of Fe in howardites ranges from about 12 to 15 wt.%. Basaltic eucrites have the highest abundance, whereas, lower crustal and upper mantle materials (cumulate eucrites and diogenites) have the lowest, and howardites are intermediate [3]. We have completed a mapping study of 7.6 MeV gamma rays produced by neutron capture by Fe as measured by the bismuth germanate (BGO) detector of GRaND [1]. The procedures to determine Fe counting rates are presented in detail here, along with a preliminary distribution map, constituting the necessary initial step to quantification of Fe abundances. We find that the global distribution of Fe counting rates is generally consistent with independent mineralogical and compositional inferences obtained by other instruments on Dawn such as measurements of pyroxene absorption bands by the Visual and Infrared Spectrometer (VIR) [4] and Framing Camera (FC) [5] and neutron absorption measurements by GRaND [6].

    2016-01-01

    In anticipation of new observational results for Jupiter's axial moment of inertia and gravitational zonal harmonic coefficients from the forthcoming Juno orbiter, we present a number of preliminary Jupiter interior models. We combine results from ab initio computer simulations of hydrogen-helium mixtures, including immiscibility calculations, with a new nonperturbative calculation of Jupiter's zonal harmonic coefficients, to derive a self-consistent model for the planet's external gravity and moment of inertia. We assume helium rain modified the interior temperature and composition profiles. Our calculation predicts zonal harmonic values to which measurements can be compared. Although some models fit the observed (pre-Juno) second- and fourth-order zonal harmonics to within their error bars, our preferred reference model predicts a fourth-order zonal harmonic whose absolute value lies above the pre-Juno error bars. This model has a dense core of about 12 Earth masses, and a hydrogen-helium-rich envelope with...

  7. The show starts here: viewers’ interactions with recent television serials’ main title sequences

    Directory of Open Access Journals (Sweden)

    2013-12-01

    Full Text Available Recent title sequences for high production value television serials are generally one of two kinds: either extremely minimal, appearing part way through the episode with credits dispersed through the show, or as an extended format of c. ninety seconds’ duration, at or near the start of the show. In a previous book chapter I presented analyses of examples of the latter, arguing that the sequences form an efficient part of the brand image for both the show and commissioning channel. In order to explore the extent to which such sequences are watched or skipped by viewers, and how such decisions are made I organised a series of preliminary focus groups in February 2012 with participants who identified themselves as regular viewers of television serials, the findings of which are presented here. Two forms of stimuli were used: a main title sequence and an end credit sequence from a serial where different music is selected for this sequence for each episode. Analysis of the discussions indicates that the decision to view these sequences is dependent on a variety of factors. While for some the titles are required viewing, the participants in the groups are more likely to persistently view an end credit sequence where the music changes with the episode than an unchanging main title sequence. Perhaps most surprising, given the increase in opportunities for mobile viewing, is that for the participants of these groups television serials continue to be associated with social viewing in a domestic setting.

    2012-04-01

    This case series describes a unique sonographic appearance consisting of numerous microcysts and punctate echogenic foci seen on renal sonograms of 10 adult patients receiving chronic lithium therapy. Clinically, chronic renal insufficiency was present in 6 and nephrogenic diabetes insipidus in 2. Sonography showed numerous microcysts and punctate echogenic foci. Computed tomography in 5 patients confirmed microcysts and microcalcifications, which were fewer in number than on sonography. Magnetic resonance imaging in 2 patients confirmed microcysts in each case. Renal biopsy in 1 patient showed chronic interstitial nephritis, microcysts, and tubular dilatation. The diagnosis of lithium nephropathy should be considered when sonography shows these findings.

    The problem of attribute reduction is an important problem related to feature selection and knowledge discovery. The problem of finding reducts with minimum cardinality is NP-hard. This paper suggests a new algorithm for finding exact reducts with minimum cardinality. This algorithm transforms the initial table to a decision table of a special kind, apply a set of simplification steps to this table, and use a dynamic programming algorithm to finish the construction of an optimal reduct. I present results of computer experiments for a collection of decision tables from UCIML Repository. For many of the experimented tables, the simplification steps solved the problem.

  16. Immunological findings in autism.

    Cohly, Hari Har Parshad; Panja, Asit

    2005-01-01

    The immunopathogenesis of autism is presented schematically in Fig. 1. Two main immune dysfunctions in autism are immune regulation involving pro-inflammatory cytokines and autoimmunity. Mercury and an infectious agent like the measles virus are currently two main candidate environmental triggers for immune dysfunction in autism. Genetically immune dysfunction in autism involves the MHC region, as this is an immunologic gene cluster whose gene products are Class I, II, and III molecules. Class I and II molecules are associated with antigen presentation. The antigen in virus infection initiated by the virus particle itself while the cytokine production and inflammatory mediators are due to the response to the putative antigen in question. The cell-mediated immunity is impaired as evidenced by low numbers of CD4 cells and a concomitant T-cell polarity with an imbalance of Th1/Th2 subsets toward Th2. Impaired humoral immunity on the other hand is evidenced by decreased IgA causing poor gut protection. Studies showing elevated brain specific antibodies in autism support an autoimmune mechanism. Viruses may initiate the process but the subsequent activation of cytokines is the damaging factor associated with autism. Virus specific antibodies associated with measles virus have been demonstrated in autistic subjects. Environmental exposure to mercury is believed to harm human health possibly through modulation of immune homeostasis. A mercury link with the immune system has been postulated due to the involvement of postnatal exposure to thimerosal, a preservative added in the MMR vaccines. The occupational hazard exposure to mercury causes edema in astrocytes and, at the molecular level, the CD95/Fas apoptotic signaling pathway is disrupted by Hg2+. Inflammatory mediators in autism usually involve activation of astrocytes and microglial cells. Proinflammatory chemokines (MCP-1 and TARC), and an anti-inflammatory and modulatory cytokine, TGF-beta1, are consistently

    The authors present the preliminary results of 20 patients selected to be operated on between January 1996 and April 1997. These patients presented one of the present indications for stereotactic posteroventral pallidotomy (PVP), such as: rigidity, akinesia/bradykinesia, gait dysfunction, drug induced dyskinesias and tremor. Every patient of this protocol was evaluated by: UPDRS score, Schwab and England scale, Hoehn and Yahr Staging Scale before and after surgery. The results in 3 months showed a remarkable improvement after PVP (P < 0.01) in all functional assessments, except for facial expression, speech and posture. The morbidity was 5%. 5 patients (25%) who were in Hoehn and Yahr 5 underwent a bilateral simultaneous PVP. In 5 patients (25%), who had tremor, during the PVP, VIM thalamotomy was added. These preliminary results, suggest that PVP is highly effective for PD symptoms.

I would like to show the chest CT scan of tuberculosis diseases with caseous granuloma at its exudative reaction, proliferative reaction, productive reaction, cirrhotic reaction until self cure. This progress reflects the normal cell mediated immunological responses. Also I would like to show the cavitation of granuloma, which results from liquefaction of caseous materials during the course and results in the formation of the source of infection. And finally I would like to show the morphological differences of acinous lesion, acino-nodular lesion and caseous lobular pneumonia. These differences reflect the amount of bacilli disseminated in the peripheral parts under the lobules. In this study, I do not show old age cases and HIV positive cases, who do not form typical granuloma due to the decreased cell mediated immnunity and whose X ray findings are atypical.

    In anticipation of new observational results for Jupiter's axial moment of inertia and gravitational zonal harmonic coefficients from the forthcoming Juno orbiter, we present a number of preliminary Jupiter interior models. We combine results from ab initio computer simulations of hydrogen–helium mixtures, including immiscibility calculations, with a new nonperturbative calculation of Jupiter's zonal harmonic coefficients, to derive a self-consistent model for the planet's external gravity and moment of inertia. We assume helium rain modified the interior temperature and composition profiles. Our calculation predicts zonal harmonic values to which measurements can be compared. Although some models fit the observed (pre-Juno) second- and fourth-order zonal harmonics to within their error bars, our preferred reference model predicts a fourth-order zonal harmonic whose absolute value lies above the pre-Juno error bars. This model has a dense core of about 12 Earth masses and a hydrogen–helium-rich envelope with approximately three times solar metallicity.

    To define the imaging patterns of xanthogranulomatous pyelonephritis (XGP). The demographic, clinical, and imaging findings of 21 cases of pathologically proven XGP in 20 patients (bilateral in one) were evaluated. The findings of ultrasonography and CT were retrospectively evaluated with regard to distribution and extent of the disease, kidney size, the presence of calculi, hydronephrosis, and renal function. The findings were assessed by two radiologists, who established a consensus. Imaging and pathologic findings were compared. Sixteen of the 20 patients were female, and 19 were adults. Their age ranged from 3 to 16 (mean, 45) years. In all patients except one, the disease was unilateral (right: left =3D 13 :16). In one patient, XGP was bilateral, and there were thus 21 cases. Seventeen (81%) of these were diffuse, and four (19%) were focal; extrarenal extension occurred in 13 cases (62%), among which ipsilateral pleural effusion was noted in two. The kidney was enlarged diffusely in 12 cases (57%), and focally in three (14%); urinary calculi were present in 16 cases (76%), with staghorn calculi in four of these; and hydronephrosis occurred in 17 (81%). Impairment of ipsilateral renal function was noted in 13 cases (62%). Clinical findings of inflammation such as fever, pyuria, bacteriuria, or leucocytosis were noted in all patients. In addition to nephromegaly, renal function impairment, and urinary obstruction due to calculi, which are typical features of XGP, the condition may also show variable imaging findings. If the images obtained in the case of a middle-aged woman with clinical findings of urinary infection are atypical, we believe that XGP should be included in the differential diagnosis. (author)

    We have experienced 14 cases of cryptococcal meningitis in the last 6 years. Their neurological signs, CT findings, and prognoses were studied. They fall into three types: the brain-stem-encephalitis type, the cortical-encephalitis type, and the meningitis type, according to the clinical course. The first type (6 cases) revealed mainly cerebellar signs, eye-movement damage, and so forth. The second type (5 cases) demonstrated ''Personality'' changes, chiefly aphasia. The third type (5 cases) did not show any focal signs. Prognosis of the brain-stem-encephalitis type was very poor, with a 50% mortality rate. In the survivors, also, clinical signs did not disappear for a long time. Repeated CT was performed in 13 among the 14 cases; abnormal CT findings were revealed in 5 cases because of cryptococcal infection. Granuloma shadow and ventriculitis shadow were observed in 3 cases each. These abnormal findings disappeared upon treatment except in one case. The clinical signs are not completely related with the CT finding, but it is useful that the site which has been infiltrated by the cryptococcus can be observed. Abnormal CT findings were observed in the 4 cases of the brain-stem-encephalitis type among the 5 abnormal cases. It is very useful to know the severity of the condition.

    To evaluate the sonographic findings of the heterotopic pregnancy which is increasing recently. Thirty-nine cases of heterotopic pregnancy after ovulation induction and IVF-ET (In Vitro Fertilization-Embryo Transfer) during the recent 3 years were analyzed. They were diagnosed by ultrasonography and proved surgically afterwards. Sonographic findings were analyzed focusing on gestational week of intrauterine pregnancy and location of ectopic pregnancy. In particular, adnexal mass was evaluated with regard to size and the characteristic findings such as ectopic gestational sac (echogenic ring). Also, overian cyst and fluid collection in cul-de-sac space were reviewed carefully. Heterotopic pregnancy was proved surgically by salpingectomy in 33 cases and by resection of cornus in six cases. Sonographic diagnosis using transvaginal ultrasound was made from five weeks to nine weeks two days (six weeks and four days in average) from last menstral period in all 39 cases. Ectopic pregnancy was identified in ampullary part in 29 cases, in the isthmic portion of tube in four cases and in the cornus of uterus in six cases. The intrauterine pregnancy was diagnosed by identifying the intrauterine gestational saccontaining a yolk sac in seven cases and the embryo with fetal heart beat in the remaining 32 cases. Adnexal masses of heterotopic pregnancy were less than 3 cm in diameter in 2 cases (57%), 3-4 cm in 11 cases (28%) and more than 4 cm in 6 cases (15%). A characteristic finding of ectopic mass was echogenic ring which was visible in 33 (84.6%) cases by transvaginal ultrasound. Six cases had pelvic hematosalpinx and two had pelvic hematoma. Of 10 cases (26%) which were identified to have ovarian hyperstimulation syndrome, eight (21%) had large amount of fluid collection in cul-de-sac and abdomen. Ultrasonographic identification of the intrauterine pregnancy and the ectopic chorion ring is effective for the early diagnosis of the heterotopic pregnancy.

    CT findings in three female epileptic patients are presented. The patients were treated with toxic doses of the anticonvulsant diphenylhydantoin, leading to irreversible ataxia of varying severity. CT shows cerebellar atrophy, including discernible sulci, a dilated 4th ventricle, basal cisterns, and subarachnoid space. These effects of severe DPH toxicity are in the differential diagnosis from the ''idiopathic'' and other toxic and systemic atrophies, as well as from the dysontogenetic lesions of the cerebellum.

    AIM: To evaluate the imaging findings of biliary hamartomas (von Meyenburg complexes, VMCs) and discuss the differential diagnosis with other related diseases.METHODS: Imaging findings of biliary hamartomas on ultrasonography (US), computed tomography (CT), magnetic resonance imaging (MRI), MR cholangiopancreatography (MRCP)and hepatobiliary scintigraphy were retrospectively analyzed in six patients.RESULTS: On ultrasound images, five of the six cases showed multiple small hyper- and hypo-echoic lesions with comet-tail echoes, especially when magnified by US with the usage of zoom function. In all the six cases,multiple tiny hypodense lesions less than 10 mm in diameter were revealed as scattered throughout the liver with no enhancement on CT. These tiny lesions were demonstrated to be hyper- and hypo-intensity on T2- and TI-weighed images, respectively, in three patients who underwent MRI examinations. MRCP was performed in two patients, and clearly showed multiple tiny irregular- and round-shaped hyper-intensity lesions.MRCP and hepatobiliary scintigraphy showed normal appearances of intra- and extra-hepatic bile ducts in two and one patients, respectively.CONCLUSION: Imaging modalities are useful in the diagnosis and differential diagnosis of VMCs. A correct diagnosis might be obtained when typical imaging findings are present even without a histological confirmation.

  9. A Technique for Showing Causal Arguments in Accident Reports

    Holloway, C. M.; Johnson, C. W.

    2005-01-01

    In the prototypical accident report, specific findings, particularly those related to causes and contributing factors, are usually written out explicitly and clearly. Also, the evidence upon which these findings are based is typically explained in detail. Often lacking, however, is any explicit discussion, description, or depiction of the arguments that connect the findings and the evidence. That is, the reports do not make clear why the investigators believe that the specific evidence they found necessarily leads to the particular findings they enumerated. This paper shows how graphical techniques can be used to depict relevant arguments supporting alternate positions on the causes of a complex road-traffic accident.

    We reviewed MR images of 50 patients with spondylolisthesis to disclose MR findings of spondylolysis. In almost half of our series, spondylolysis was detected as a low signal intensity band traversing in the pairs interarticularis on both T1 and T2 weighted images. Sagittal images was superior to axial image in detection of the low signal intensity band. In some patients, a focal high signal intensity accompanying the low signal intensity band was considered to be fluid collection within pseudoarthrosis due to spondylolysis on T2-weighted image.

    Full Text Available A preliminary survey was conducted for the presence of helminths in the city of Montes Claros, M. G., Brazil. Three groups of persons were examined by the direct smear, Kato thick film and MIFC techniques; one group by direct smear and Kato only. General findings were: a high prevalence of hookworm, followed by ascariasis, S. mansoni, S. stercoralis and very light infections with T. trichiurá. E. vermicularis and H. nana were ranking parasites at an orphanage, with some hookworm and S. mansoni infections as well. At a pig slaughter house, the dominant parasites were hookworm and S. mansoni. Pig cysticercosis was an incidental finding worth mentioning for the health hazard it represents for humans as well as an economic loss. From the comparative results between the Kato and the MIF the former proved itself again as a more sensitive and reliable concentration method for helminth eggs, of low cost and easy performance.

    We discuss two constructions for obtaining generically stable Keisler measures in an NIP theory. First, we show how to symmetrize an arbitrary invariant measure to obtain a generically stable one from it. Next, we show that suitable sigma-additive probability measures give rise to generically stable measures. Also included is a proof that generically stable measures over o-minimal theories and the p-adics are smooth.

    Though cortical abnormalities have been demonstrated in moderate and severe traumatic brain injured (TBI) patients, there have been no studies examining cortical changes following blast related mild TBI (mTBI). The purpose of this study was to determine the effects and functional relevance of blast mTBI on cortical thickness in a small cohort of carefully screened blast injured US Service Members (SM). Twelve SM with mTBI acquired through blast injury were compared to 11 demographically matched control SM without TBI. Both mTBI and control participants were active duty and had completed a combat deployment. Subjects underwent MRI examination and the T1 weighted anatomic images were processed using the FreeSurfer suite of tools. Cortical thickness maps were compared between groups and examined for relationships with time since injury (TSI). Utilizing a large database of functional imaging results (BrainMap), significant regions of interest (ROI) were used to determine the behavioral profiles most consistently associated with the specific ROI. In addition, clinical variables were examined as part of post-hoc analysis of functional relevance. Group comparisons controlling for age demonstrated several significant clusters of cortical thinning for the blast injured SM. After multiple comparisons correction (False Discovery Rate (FDR)), two left hemisphere clusters remained significant (left superior temporal (STG) and frontal (SFG) gyri). No clusters were significantly correlated with TSI after FDR correction. Behavioral analysis for the STG and SFG clusters demonstrated three significant behavioral/cognitive sub-domains, each associated with audition and language. Blast injured SMs demonstrated distinct areas of cortical thinning in the STG and SFG. These areas have been previously shown to be associated with audition and language. Post-hoc analyses of clinical records demonstrated significant abnormal audiology reports for the blast injured SM suggesting that the thinning in these ROIs might be related to injury to the external auditory system rather than direct injury to the brain from the blast. It is clear that additional replication is needed in much larger cohorts. Importantly, the combination of imaging tools and methods in this study successfully demonstrated the potential to define unique ROIs and functional correlates that can be used to design future studies.

    Objective: In order to retrospectively evaluate the CT findings of abdominal aspergillosis in immunocompromised patients. Materials and methods: CT scans were reviewed with regard to the sites, number, morphologic appearance, attenuation, and the contrast enhancement patterns of the lesions in six patients (5 women, 1 man; mean age, 43.4 years; range, 23-59 years) with pathologically proved abdominal aspergillosis by two gastrointestinal radiologists in consensus. Medical records were also reviewed to determine each patient's clinical status and outcome. Results: All patients were immunocompromised state: 4 patients received immunosuppressive therapy for solid organ transplantation and 2 patients received chemotherapy for acute myeloid leukemia. Aspergillosis involved blood vessels (n = 3), liver (n = 2), spleen (n = 2), gastrointestinal tract (n = 2), native kidney (n = 1), transplanted kidney (n = 1), peritoneum (n = 1), and retroperitoneum (n = 1). CT demonstrated solid organ or bowel infarction or perforation secondary to vascular thrombosis or pseudoaneurysm, multiple low-attenuating lesions of solid organs presenting as abscesses, concentric bowel wall thickening mimicking typhlitis, or diffuse or nodular infiltration of the peritoneum and retroperitoneum. Conclusion: Familiarity with findings commonly presenting as angioinvasive features or abscesses on CT, may facilitate the diagnosis of rare and fatal abdominal aspergillosis.

    To evaluate the usefulness of ultrasonographic findings of the common extensor and flexor tendon in evaluation of patients with lateral and medial epicondylitis. Thirty eight elbows from twenty four patients (mean age=45.2 years) were included. Ultrasonographic examination was performed to evaluate lateral or medial epicondylitis. Epicondylitis was divided into five groups according to the severity of disease: 1) normal, 2) tendinopathy, 3) tendinopathy with a partial tear, partial tear and 4) complete tear. Change in the size of a tendon, bony change of the epicondylitis, presence or absence of calcification or echogenic foci in the common tendon and hypervascularity for each categories were also assessed. In addition, these lesions were divided into the superficial and deep according to the location of lesions. According to the severity, there were 15 cases of normal, 13 tendinopathies, 8 tendinopathies with a partial tear, 2 partial tears and 0 complete tear. Bony change was seen only in tendinopathy, tendinopathy with partial tear and partial tear. Calcification or echogenic foci were only observed in cases with tendinopathy and tendinopathy with partial tear. Hypervascularity was only seen in one case of tendinopathy. With thorough understanding of ultrasonographic findings of epicondylitis, ultrasonographic examination can be especially useful and effective in evaluating the severity and location of lesions.

    To describe and characterize the CT findings of the sternal masses. We retrospectively reviewed the medical records, pathologic reports, and CT findings of 16 patients whose chest CT revealed sternal masses. Two primary tumors were found, namely chondrosarcomas. Twelve metastatic tumors had arisen were from lung cancer (n = 4), breast cancer (n = 3), hepatoma (n 2), osteosarcoma (n = 1), carotid body paraganglioma (n = 1), and immature sacrococcygeal teratoma (n = 1). Other were Castleman's disease (n = 1) and inflammatory pseudotumor (n = 1). Chondrosarcomas were large expansile osteolytic masses showing a variable degree of cortical breakthrough and containing punctuate chondroid calcifications. Most sternal metastases (83 %) were located in the manubrium and were accompanied by metastasis in other bones (83 %). Metastatic tumors were nonspecific osteolytic soft tissue masses showing homogeneous or inhomogeneous enhancement, except for those which arose from an osteosarcoma and a lung cancer, and showed osteoblastic lesions. Castleman's disease was seen as an ill-defined enhanced soft tissue mass involving the sternum and adjacent soft tissue. Inflammatory pseudotumor appeared as an infiltrating lesion around the sternoclavicular joint and was accompanied by sclerosis and the erosion of opposing sternal and clavicular ends. Most of the sternal masses are due to malignant neoplasms, among which metastatic tumors are more common than primary ones. Metastatic tumors affect the manubrium more commonly than the body portion, and most also affect other bones in the thorax. CT findings of metastatic tumors are non-specific and thus do not suggest their origin. Non-neoplastic masses are not readily differentiated from malignant tumors on the basis of CT findings alone and require pathological confirmation.

  17. Preliminary Benefits Assessment of Traffic Aware Strategic Aircrew Requests (TASAR)

    2012-01-01

    While en route, aircrews submit trajectory change requests to air traffic control (ATC) to better meet their objectives including reduced delays, reduced fuel burn, and passenger comfort. Aircrew requests are currently made with limited to no information on surrounding traffic. Consequently, these requests are uninformed about a key ATC objective, ensuring traffic separation, and therefore less likely to be accepted than requests informed by surrounding traffic and that avoids creating conflicts. This paper studies the benefits of providing aircrews with on-board decision support to generate optimized trajectory requests that are probed and cleared of known separation violations prior to issuing the request to ATC. These informed requests are referred to as traffic aware strategic aircrew requests (TASAR) and leverage traffic surveillance information available through Automatic Dependent Surveillance Broadcast (ADS-B) In capability. Preliminary fast-time simulation results show increased benefits with longer stage lengths since beneficial trajectory changes can be applied over a longer distance. Also, larger benefits were experienced between large hub airports as compared to other airport sizes. On average, an aircraft equipped with TASAR reduced its travel time by about one to four minutes per operation and fuel burn by about 50 to 550 lbs per operation depending on the objective of the aircrew (time, fuel, or weighted combination of time and fuel), class of airspace user, and aircraft type. These preliminary results are based on analysis of approximately one week of traffic in July 2012 and additional analysis is planned on a larger data set to confirm these initial findings.

    Some studies have reported the importance of electroencephalography (EEG) as a method for investigating abnormal parameters in psychiatric disorders. Different findings in time and frequency domain analysis with regard to central nervous system arousal during acute panic states have already been obtained. This study aimed to systematically review the EEG findings in panic disorder (PD), discuss them having a currently accepted neuroanatomical hypothesis for this pathology as a basis, and identify limitations in the selected studies. Literature search was conducted in the databases PubMed and ISI Web of Knowledge, using the keywords electroencephalography and panic disorder; 16 articles were selected. Despite the inconsistency of EEG findings in PD, the major conclusions about the absolute power of alpha and beta bands point to a decreased alpha power, while beta power tends to increase. Different asymmetry patterns were found between studies. Coherence studies pointed to a lower degree of inter-hemispheric functional connectivity at the frontal region and intra-hemispheric at the bilateral temporal region. Studies on possible related events showed changes in memory processing in PD patients when exposed to aversive stimuli. It was noticed that most findings reflect the current neurobiological hypothesis of PD, where inhibitory deficits of the prefrontal cortex related to the modulation of amygdala activity, and the subsequent activation of subcortical regions, may be responsible to trigger anxiety responses. We approached some important issues that need to be considered in further researches, especially the use of different methods for analyzing EEG signals.

    This report documents the activities and findings of the Phase I Preliminary Characterization of Abandoned Septic Tank Systems. The purpose of the preliminary characterization activity was to investigate the Tiger Team abandoned septic systems (tanks and associated leachfields) for the purpose of identifying waste streams for closure at a later date. The work performed was not to fully characterize or remediate the sites. The abandoned systems potentially received wastes or effluent from buildings which could have discharged non-domestic, petroleum hydrocarbons, hazardous, radioactive and/or mixed wastes. A total of 20 sites were investigated for the preliminary characterization of identified abandoned septic systems. Of the 20 sites, 19 were located and characterized through samples collected from each tank(s) and, where applicable, associated leachfields. The abandoned septic tank systems are located in Areas 5, 12, 15, 25, and 26 on the Nevada Test Site.

    To evaluate by means of retrospective analysis of neck CT scans the CT findings which suggest kikuchi disease. The authors evaluated the CT findings of seven cases of Kikuchi disease histologically confirmed by excisional biopsy. Four males and three females aged between 12 and 43 (mean;28) years were included. The authors retrospectively analyzed distribution, bilaterality, the presence of aggregation, the presence of intranodal low density after contrast enhancement, the number,size, shape and location of areas of intranodal low density, and the presence of extracapsular extension in involved nodes, as seen on pre-and post-contrast CT scans. Attempts were then made to correlate the CT with the pathologic findings. The range of conditions affecting patients included palpable(7/7) and tender(6/7) nodes, fever(5/7), night sweat(2/7), leukopenia(2/7), and weight loss(1/7). The internal jugular and spinal accessory chains were involved in all seven cases, followed by the submandibular(6/7), submental(5/7), supraclavicular(1/7) and axillary(1/7) nodes. The findings observed also included bilateral involvement of the internal jugular chain(6/7), the spinal accessory chain(5/7), and the submandibular(4/6) and supraclavicular nodes(1/1). CT revealed that in all cases, pathologic lymph nodes showed aggregation in one or several nodal groups, namely a mixed homogeneous(mean, 60%)or inhomogeneous(mean, 40%) enhancement pattern;intranodal low densities with the number(1-7), size(1-7mm) and shape(oval, round, or elongated) of varying degree and predominantly (92%) peripheral location, and extracapsular extension. The CT findings which suggest Kikuchi disease in cervical lymphadenopathy were (1) involvement varying from no intranodal low density to prominent intranodal low densities; (2) intranodal low densities, with the number, size and shape of varying degree and predominantly peripheral location, which were correlated with pathologic findings, including variable intranodal

    The pulmonary aspergillosis is a group of three separate disease, comprising invasive aspergillosis, aspergilloma, and allergic bronchopulmonary aspergillosis, or a disease process in which one of three entities overlap with another process such as mucoid impaction, pulmonary infiltration with eosinophilia, bronchocentric granulomatosis, microgranulomatous hypersensitivity, or asthma. The radiological findings of 24 cases of pulmonary aspergillosis diagnosed and treated at Seoul National University Hospital during the past 7 years were analyzed retrospectively. The results were as follows: 1. Final diagnosis of 24 cases of pulmonary aspergillosis was aspergilloma in 16 cases, invasive aspergillosis in 2 cases, variant form of allergic bronchopulmonary aspergillosis in 3 cases, and endobronchial aspergillosis in 3 cases. 2. The underlying causes of the aspergilloma were healed tuberculous cavity in 6 cases, bronchiectasis in 8 cases, and no underlying cause were found in 2 cases. All the 16 cases of aspergilloma were correctly diagnosed without difficultly by demonstrating the intracavitary mass or air meniscus. 3. Radiological findings of the invasive aspergillosis in kidney transplant patients were multiple round nodules with early cavitation and formation of aspergilloma which shows slowly progressive cavitation over 13 months in one case, and diffusely scattered miliary nodules with occasional cavitation in the other case. 4. Classic allergic bronchopulmonary aspergillosis were not found in our series but variant form of ABPA was found in 3 young female patients. All the three patients shows some degree of central bronchiectasis and combined aspergilloma was found in 2 cases. 5. Three patients diagnosed as endobronchial aspergillosis-saprophytic infection of aspergillus in the bronchial tree-by bronchoscopic biopsy shows nonspecific radiological findings.

    Objective: the aim of this study was to analyze chest CT scans of patients with thoracic textiloma. Methods: this was a retrospective study of 16 patients (11 men and 5 women) with surgically confirmed thoracic textiloma. The chest CT scans of those patients were evaluated by two independent observers, and discordant results were resolved by consensus. Results: the majority (62.5%) of the textilomas were caused by previous heart surgery. The most common symptoms were chest pain (in 68.75%) and cough (in 56.25%). In all cases, the main tomographic finding was a mass with regular contours and borders that were well-defined or partially defined. Half of the textilomas occurred in the right hemithorax and half occurred in the left. The majority (56.25%) were located in the lower third of the lung. The diameter of the mass was ≤ 10 cm in 10 cases (62.5%) and > 10 cm in the remaining 6 cases (37.5%). Most (81.25%) of the textilomas were heterogeneous in density, with signs of calcification, gas, radiopaque marker, or sponge-like material. Peripheral expansion of the mass was observed in 12 (92.3%) of the 13 patients in whom a contrast agent was used. Intraoperatively, pleural involvement was observed in 14 cases (87.5%) and pericardial involvement was observed in 2 (12.5%). Conclusions: it is important to recognize the main tomographic aspects of thoracic textilomas in order to include this possibility in the differential diagnosis of chest pain and cough in patients with a history of heart or thoracic surgery, thus promoting the early identification and treatment of this postoperative complication.

    We have completed a preliminary study using filter media tests and filter qualification tests to investigate the effect of shelf-life on HEPA filter performance. Our media studies showed that the tensile strength decreased with age, but the data were not sufficient to establish a shelf-life. Thermogravimetric analyses demonstrated that one manufacturer had media with low tensile strength due to insufficient binder. The filter qualification tests (heated air and overpressure) conducted on different aged filters showed that filter age is not the primary factor affecting filter performance; materials and the construction design have a greater effect. An unexpected finding of our study was that sub-standard HEPA filters have been installed in DOE facilities despite existing regulations and filter qualification tests. We found that the filter with low tensile strength failed the overpressure test. The same filter had passed the heated air test, but left the filter so structurally weak, it was prone to blow-out. We recommend that DOE initiate a filter qualification program to prevent this occurrence.

    Heel pain is a common and frequently disabling clinical complaint that may be caused by a broad spectrum of osseous or soft-tissue disorders. These disorders are classified on the basis of anatomic origin and predominant location of heel pain to foster a better understanding of this complaint. The disorders include plantar fascial lesions (fasciitis, rupture, fibromatosis, xanthoma), tendinous lesions (tendinitis, tenosynovitis), osseous lesions (fractures, bone bruises, osteomyelitis, tumors), bursal lesions (retrocalcaneal bursitis, retroachilleal bursitis), tarsal tunnel syndrome, and heel plantar fat pad abnormalities. With its superior soft-tissue contrast resolution and multiplanar capability, magnetic resonance (MR) imaging can help determine the cause of heel pain and help assess the extent and severity of the disease in ambiguous or clinically equivocal cases. Careful analysis of MR imaging findings and correlation of these findings with patient history and findings at physical examination can suggest a specific diagnosis in most cases. The majority of patients with heel pain can be successfully treated conservatively, but in cases requiring surgery (eg, plantar fascia rupture in competitive athletes, deeply infiltrating plantar fibromatosis, masses causing tarsal tunnel syndrome), MR imaging is especially useful in planning surgical treatment by showing the exact location and extent of the lesion.

    In this study, CT findings of eight patients with Japanese encephalitis were analyzed. In principle, CT scans were done at the acute stage, within 3 weeks of the onset, and at the convalescent stage, after from 1 month to 1 year. The results may be divided into three groups: normal scans, low-density lesions, and ventricular abnormalities. 1) Normal scans: CT findings in Cases 1 and 5, showed no abnormalities, although patient 5 had clinically severe encephalitis. 2) Low-density lesions: In Case 3, a slight low-density area was observed in the bilateral thalami only at the acute stage. CT scans in Case 4, obtained 2 and 4 months after the onset, exhibited low-density areas in the bilateral thalami, the left basal ganglia, and the left substantia nigra. In Case 7, diffuse low-density areas in the white matter were found 3 months after the onset. 3) Ventricular abnormalities: CT in Case 2 revealed a moderate dilatation of the ventricular system, which probably suggests normal-pressure hydrocephalus. In 2 other cases, a narrowing or dilatation of the lateral ventricle was observed. The CT findings regarding Japanese encephalitis were discussed in comparison with those of other viral encephalitides, particularly herpes simplex encephalitis.

    A CT scan can make accurate diagnoses of most thymic masses by assessing their size, shape, and internal architecture and is especially effective in detecting pleural implants, mediastinal involvement, and pulmonary parenchymal invasion in malignant thymoma. The authors analyzed the CT findings of 10 histologically-proven thymic masses from 1983 to 1990 in Yeungnam University Hospital. There were 10 cases of thymic masses in the anterior mediastinum consisting of 6 benign, 3 invasive thymomas, and one thymolipoma, while myasthenia gravis was associated with 2 cases of benign thymomas and with one case of invasive thymomas. The CT findings of the benign thymomas (6 cases) were well-defined, bordered, round-or oval-shaped masses with a well-preserved fat plane between the thymic mass and mediastinal great vessels, with no evidence of pleural implants and lung parenchymal invasion. The CT findings of the invasive thymomas (3 cases) were irregular, marginated lobular masses with obliteration of the fat plane between the thymic mass and surrounding great vessels, with evidence of local invasion such as extension to A-P window and mass effect to bronchus. Irregular pleural thickening due to pleural metastasis, multiple metastatic lung parenchymal nodules, and multiple mediastinal lymph node enlargement were also seen in the invasive thymomas. One case of thymolipoma showed an approximately 20cm-size, well-defined fat density mass containing internal septations.

    Full Text Available Abstract Background The presence of antiphospholipid antibodies (APLA in multiple sclerosis (MS patients has been reported frequently but no clear relationship between APLA and the clinical and neuroimaging features of MS have heretofore been shown. We assessed the clinical and neuroimaging features of MS patients with plasma APLA. Methods A consecutive cohort of 24 subjects with relapsing-remitting (RR MS were studied of whom 7 were in remission (Rem and 17 in exacerbation (Exc. All subjects were examined and underwent MRI of brain. Patients' plasma was tested by standard ELISA for the presence of both IgM and IgG antibodies using a panel of 6 targets: cardiolipin (CL, β2 glycoprotein I (β2GPI, Factor VII/VIIa (FVIIa, phosphatidylcholine (PC, phosphatidylserine (PS and phosphatidylethanolamine (PE. Results In exacerbation up to 80% of MS subjects had elevated titers of IgM antibodies directed against the above antigens. However, in remission, less than half of MS patients had elevated titers of IgM antibodies against one or more of the above antigens. This difference was significant, p Conclusion The findings of this preliminary study show that increased APLA IgM is associated with exacerbations of MS. Currently, the significance of this association in pathogenesis of MS remains unknown. However, systematic longitudinal studies to measure APLA in larger cohorts of patients with relapsing-remitting MS, particularly before and after treatment with immunomodulatory agents, are needed to confirm these preliminary findings.

    To analyze the MR findings of cyclosporine-induced neurotoxicity in patients receiving high dose of cyclosporine and to suggest the possible pathogenetic mechanism. The cases of seven patients (2 males, 5 females;18-36 years old) who suffered seizures after receiving high-dose cyclosporine for bone marrow transplantation due to diseases such as aplastic anemia or leukemia were retrospectively reviewed. We evaluated the location and pattern of abnormal signal intensity seen on T2 weighted images, the presence of contrast enhancement, and the changes seen on follow-up MR performed at intervals of 12-30 days after initial MR in five of seven patients. We analyzed levels of blood cyclosporine and magnesium, and investigated the presence of hypertension at the sity of the seizure. Locations of the lesions were bilateral(n=3D5), unilateral(n=3D2), parietal(n=3D6), occipital(n=3D6), temporal(n=3D4), and in the frontal lobe(n=3D3). Frontal lesions showed high signal intensities in the borderline ischemic zone of the frontal lobe between the territory of the anterior and middle cerebral arteries. In six of the seven patients, cortical and subcortical areas including subcortical U-fibers were seen on T2-weighted images to be involved in the parietooccipital lobes. Only one of the seven showed high signal intensity in the left basal ganglia. All lesions showed high signal intensity on T2-weighted images, and iso to low signal intensity on T1-weighted. In five of seven patients there was no definite enhancement, but in the other two, enhancement was slight. In four of seven patients seizures occurred within high therapeutic ranges(250-450ng/ml), while others suffered such attacks at levels below the therapeutic range. After cyclospirine was administered at a reduced dosage or stopped, follow-up MR images showed the complete or near-total disappearance of the abnormal findings previously described. Only two patients had hypertension, and the others normotension. Five of the

    A 59-year-old female with carcinoma of the colon and known liver metastatic disease was referred for bone scan to evaluate for bone metastases. Although no bone metastases were found, there was abnormal uptake noted in the liver corresponding to a metastatic calcified lesion. The only other findings were of degenerative disease in the cervical spine, right shoulder and small joints of the hands. A 69-year-old male with carcinoma of the prostate and right side low back pain was referred for bone scan. No focal abnormalities to suggest metastatic disease were identified; findings within the cervical spine, lumber spine and knees were presumed secondary to degenerative disease. Intermittent pain persisted and the patient was referred for a repeat bone scan six months later. Previous scan findings of degenerative disease and no metastatic disease were confirmed; however, closer inspection revealed an enlarged right kidney with significant retention of tracer in the pelvicalyceal system suggesting possible obstruction. A Retrograde pyelogram was performed, and no obvious obstruction demonstrated. As bone scan findings were very suggestive of obstruction, a DTPA scan with lasix was performed showing a dilated right collecting system with no functional obstruction. Given the degree of dilation, it is possible that the patient experiences intermittent PUJ obstruction causing his symptoms. A 33-year-old male with insulin dependent diabetes mellitus and viral arthritis was referred for a bone scan. A three phase revealed increased uptake in the region of the knee and leR proximal tibia. Delayed whole body images revealed multiple focal areas of osteoblastic activity in the leR tibia. Abnormal uptake was also seen in the upper third of the leR femur. The remainder of the skeletal survey was normal. X-ray correlation of the leR tibia and femoral findings was undertaken. Combinating unilateral changes on bone scan and X-ray although very suggestive of sclerotic polyostotic

    Full Text Available Some studies have reported the importance of electroencephalography (EEG as a method for investigating abnormal parameters in psychiatric disorders. Different findings in time and frequency domain analysis with regard to central nervous system arousal during acute panic states have already been obtained. This study aimed to systematically review the EEG findings in panic disorder (PD, discuss them having a currently accepted neuroanatomical hypothesis for this pathology as a basis, and identify limitations in the selected studies. Literature search was conducted in the databases PubMed and ISI Web of Knowledge, using the keywords electroencephalography and panic disorder; 16 articles were selected. Despite the inconsistency of EEG findings in PD, the major conclusions about the absolute power of alpha and beta bands point to a decreased alpha power, while beta power tends to increase. Different asymmetry patterns were found between studies. Coherence studies pointed to a lower degree of inter-hemispheric functional connectivity at the frontal region and intra-hemispheric at the bilateral temporal region. Studies on possible related events showed changes in memory processing in PD patients when exposed to aversive stimuli. It was noticed that most findings reflect the current neurobiological hypothesis of PD, where inhibitory deficits of the prefrontal cortex related to the modulation of amygdala activity, and the subsequent activation of subcortical regions, may be responsible to trigger anxiety responses. We approached some important issues that need to be considered in further researches, especially the use of different methods for analyzing EEG signals. Keywords: Electroencephalography, panic disorder, neurobiology, brain mapping.

    Patients with Parkinson's disease (PD) may develop progressive dementia late in their clinical course. Dementia in PD is mostly related to neuropathological findings of extensive Lewy bodies (LBs), with or without the coexistence of Alzheimer's disease (AD) pathology. Aphasia has been reported in patients with LB diseases with AD pathology; however, there have been no reports of typical PD patients developing progressive aphasia during their clinical course.

    Full Text Available The study analyses the effects of the preliminary rulings rendered by the Court of Justice for the judicial body that made the reference and for other bodies dealing with similar cases, for the member states, for the European Union’ s institutions and for EU legal order. Starting from the binding effect of the preliminary judgment for national judicial bodies, which requires them to follow the ruling or make a new reference, to the lack of precedent doctrine in EU law, continuing with the possibility to indirectly verify the compatibility of national law of the member states with EU law and ending with the administrative or legislative measures that can or must be taken by the member states, the study intends to highlight the limits, nuances and consequences of the binding effect. It mentions the contribution of the national courts and of the Court of Justice of the European Union to the development of EU law, such as clarifying autonomous notions and it emphasizes the preliminary procedure's attributes of being a form of judicial protection of individual rights, as well as a means to review the legality of acts of EU institutions. The paper is meant to be a useful instrument for practitioners. Therefor, it also deals with the possibility and limits of asking new questions, in order to obtain reconsideration or a refinement of the legal issue and with the problem of judicial control over the interpretation and application of the preliminary ruling by the lower court.

  18. Mixtures of thermostable enzymes show high performance in biomass saccharification.

    Optimal enzyme mixtures of six Trichoderma reesei enzymes and five thermostable enzyme components were developed for the hydrolysis of hydrothermally pretreated wheat straw, alkaline oxidised sugar cane bagasse and steam-exploded bagasse by statistically designed experiments. Preliminary studies to narrow down the optimization parameters showed that a cellobiohydrolase/endoglucanase (CBH/EG) ratio of 4:1 or higher of thermostable enzymes gave the maximal CBH-EG synergy in the hydrolysis of hydrothermally pretreated wheat straw. The composition of optimal enzyme mixtures depended clearly on the substrate and on the enzyme system studied. The optimal enzyme mixture of thermostable enzymes was dominated by Cel7A and required a relatively high amount of xylanase, whereas with T. reesei enzymes, the high proportion of Cel7B appeared to provide the required xylanase activity. The main effect of the pretreatment method was that the required proportion of xylanase was higher and the proportion of Cel7A lower in the optimized mixture for hydrolysis of alkaline oxidised bagasse than steam-exploded bagasse. In prolonged hydrolyses, less Cel7A was generally required in the optimal mixture. Five-component mixtures of thermostable enzymes showed comparable hydrolysis yields to those of commercial enzyme mixtures.

    CO2 EOR may be the key to recovering hundreds of millions of bbl of trapped oil from the mature fields in central Kansas. A simple model aided in assessing the economics of CO2 EOR for central Kansas and the Midcontinent. The model used CO2 Prophet, a DOE freeware reservoir numerical simulation program, to determine reservoir performance, including injected and produced fluid rates, and CO2 utilization. Economic parameters, e.g., oil price, CO2 costs, capital costs, net revenue interest, production taxes, and lease operating expenses, are typical for anticipated conditions in the region and present price climate. Preliminary economic analysis shows that CO2 EOR should give an internal rate of return (IRR) > 20%, before income tax, assuming oil sells for $20/bbl, CO2 costs $1/million cu ft, and gross utilization is 10 million cu ft of CO2/bbl of oil recovered. If the CO2 is reduced to $0.75/million cu ft, an oil price of $17/bbl yields an IRR of 20%. Reservoir and economic modeling shows that IRR is most sensitive to oil price and CO2 cost.

    Acromegaly involves cardiovascular complications mostly due to the presence of hypertension, diabetes and atherosclerosis. However the appearance of cardiac decompensation and arrhythmias in the absence of predisposing factors tends to support the hypothesis of a specific myocardiopathy caused by excess GH. In order to assess the existence and course of subclinical cardiac alterations, 8 acromegaly patients were examined: 4 males and 4 females aged 31-56 with GH levels of 24-70 ng/ml (M + CD X 47 +/- 16) and no cardiovascular symptoms. One of the patients had moderate hypertension and 2 reduced glucose tolerance. The basal ECG showed sporadic ventricular extrasystoles in 2 cases and alterations compatible with left ventricular hypertrophy in another, while the effort ECG produced an asymptomatic depression of the ST segment in the hypertensive patient. The chest X-ray was normal in all cases. The echocardiography study investigated: the thickness of the interventricular septum (IVS = 13.9 +/- 2.8 mm), the thickness of the posterior wall of the left ventricle (LPW = 10.6 +/- 2.9 mm), the septum/posterior wall ratio (IVS/LPW = 1.3 +/- 0.2 the diastolic diameter (DD = 15.4 +/- 11.4 mm), the fraction of shortening (FS = 39.1 +/- 14.5%), the ejection fraction (EF = 64.1 +/- 18.4%) and revealed asymmetrical septal hypertrophy in 3 cases, concentric hypertrophy in another two. In two cases the DD and EF were distinctly altered. The patients were re-examined 2-4 years after surgical or radiation treatment. GH levels (M +/- SD = 10.3 +/- 10.1 ng/ml) were normal in 4 cases and still high, though lower in another two. The remaining two patients had borderline GH levels with high Sm-C. The ECG and chest X-ray were unchanged while echocardiography revealed a significant deterioration in heart function as far as DD (56.4 +/- 10.8 mm, p less than 0.05) were concerned with frankly pathological results in 4 and 3 cases respectively. These data confirm the view that most acromegalic

    Patients with Parkinson's disease (PD) may develop progressive dementia late in their clinical course. Dementia in PD is mostly related to neuropathological findings of extensive Lewy bodies (LBs), with or without the coexistence of Alzheimer's disease (AD) pathology. Aphasia has been reported in patients with LB diseases with AD pathology; however, there have been no reports of typical PD patients developing progressive aphasia during their clinical course. We describe a female PD patient who later developed progressive conduction aphasia characterized by phonemic paraphasia and disturbance in repetition of short sentences without disturbance in writing or auditory comprehension. No episodes of fluctuations of attention, memory complaints, or planning errors were observed. She experienced episodes of visual hallucination. Her low scores on the Mini-Mental State Examination suggested impairment of orientation and attention, and her scores on Raven's Coloured Progressive Matrices test indicated impaired visuospatial functions. However, her cognitive deficits were not sufficiently severe to impair her daily life. Brain magnetic resonance images revealed atrophy of the left superior temporal gyrus and widening of the left sylvian fissure. [(18)F]-fluorodeoxyglucose positron emission tomography revealed glucose hypometabolism in the left cerebral hemisphere. These findings may be related to conduction aphasia. During the progression of PD lesions, the brainstem LB is assumed to take an upward course, extend to the limbic system, and then extend to the neocortex. Conduction aphasia observed in our patient may be associated with an unusual progression of the LB pathology from the brainstem to the left temporoparietal lobe.

    Two cases of osteogenesis imperfecta found in one family (father and daughter) are reported, and the CT findings are described. Case 1 is a 58-year-old man who fell and struck his head at home on November 10, 1984. He was transferred to Omuta City Hospital when he became semicomatose and decerebrate posturing was noted. His family history revealed 8 persons with osteogenesis imperfecta. A skull X-ray film showed a large skull vault, many wormian bones at the lambdoid suture, platybasia, and a basilar impression. A CT scan demonstrated a right acute subdural hematoma, while the bone image showed well-developed mastoid air cells and a skull deformity characteristic of osteogenesis imperfecta. He had an emergency operation, and a 170-gr clot was successfully evacuated. A postoperative CT scan demonstrated brain atrophy, possibly present before head trauma. Case 2 is the daughter of Case 1 (a 27-year-old woman). She also showed characteristic neuroradiological manifestations on a plain skull film and on a CT scan. A basilar impression and platybasia were also demonstrated. In this report, the possible mechanism of the production of a traumatic acute subdural hematoma is also discussed.

    Ultrasound(US) findings of hyperechoic renal medulla in gouty nephropathy were compared with clinical features such as serum uric acid level to evaluate its usefulness in determination of the treatment and prognosis. A retrospective review of US of 36 cases of qouty arthritis was classified into four groups according to the medullary echogenicity (O :normal, grade I: renal medulla as isoechoic as renal cortex, grade II; heterogeneous increased echogenicity of renal medulla than that of renal cortex, grade III: the echogenicity of all renal medulla higher than that of renal cortex with renal contour deformity) which were compared with the serum urate level and associated conditions. Nephrocalcinosis and nephrolithiasis were analyzed through the KUB and the RGB. The degree of hyperechoic renal medulla was related to the level of serum uric acid, and in group IV, six cases of obstructive uropathy (nephrocalcinosis and nephrolithiasis) showed deformed renal contour. Associated conditions such as hypertension, alcoholism, diabetes mellitus and drug abuse were distributed in relation to the degree of hyperechoic renal medullas. US findings of hyperechoic renal mebulla was related with uric acid level in gouty nephropathy and thus could be valuable for treatment decision and prediction of prognosis.

    To demonstrate the clinical usefulness of ultrasonography for detecting esophageal varices. In 20 cases of esophaged varix, the authors analysed the transabdominal ultrasonographic findings of the esophagogastric junction and compared mural thickness, the anteroposterior diameter of the esophagus, and the echogenic nature of the esophageal mucosal layer with those of 78 normal patients. The anterior and posterior mural thickeness of normal esophagus was 2.2{+-}0.7 and 2.4{+-}0.8mm respectively, but for variceal esophagus, the corresponding readings were 5.9{+-}1.3 and 5.2{+-}1.3mm respectively. The anteroposterior diameter of normal esophagus was 7.9{+-}2.1mm and that of variceal esophagus was 14.0{+-}1.8mm. There was a stastically significant difference (p<0.01) in mural thickness and anteroposterior diameter of the esophagus between a normal and variceal patient with regard to change of echogenic nature at the esphagogastric junction. Normal esophageal mucosa showed a thin and uniform echogenic line, but for variceal mucosa, the echogenic pattern was irregular, tortuous and thick. The athors believe that transabdominal US is helpful for detecting esophageal varices in patients with liver cirrhosis and UGI bleeding. Important clinically useful sonographic findings in diagnosing esophageal varix are as follows:1) mural thickness more than 6mm; 2) anteroposterior diameter of the esophagus of more than 15mm;3) irregular, tortuous and thickened echogenic mucosa.

    Introduction: To evaluate the computed tomographic (CT) findings of primary thyroid lymphoma. Methods and material: The clinicopathological data and CT images of nine patients with primary thyroid lymphoma were retrospectively reviewed. The CT appearances were classified into three types: type 1, a solitary nodule surrounded by normal thyroid tissue; type 2, multiple nodules in the thyroid, and type 3, a homogeneously enlarged both thyroid glands with a reduced attenuation with or without peripheral thin hyperattenuating thyroid tissue. Results: All patients had a rapidly enlarging thyroid mass and coexistent Hashimoto's thyroiditis. One patient showed type 1 pattern, three type 2, and five type 3. Six patients had homogeneous tumor isoattenuating to surrounding muscles. The tumors had a strong tendency to compress normal remnant thyroid and the surrounding structure without invasion. Conclusion: Primary thyroid lymphoma should be included in the differential diagnosis when old female had a homogeneous thyroidal mass isoattenuating to muscles, which does not invade surrounding structures.

    Full Text Available The Internet has changed media fandom in two main ways: it helps fans connect with each other despite physical distance, leading to the formation of international fan communities; and it helps fans connect with the creators of the TV show, deepening the relationship between TV producers and international fandoms. To assess whether Italian fan communities active online are indeed part of transnational online communities and whether the Internet has actually altered their relationship with the creators of the original text they are devoted to, qualitative analysis and narrative interviews of 26 Italian fans of American TV shows were conducted to explore the fan-producer relationship. Results indicated that the online Italian fans surveyed preferred to stay local, rather than using geography-leveling online tools. Further, the sampled Italian fans' relationships with the show runners were mediated or even absent.

After the droplets are dried (upper right), they are viewed with crossed polarizers that show the deformation caused by drying, a process that orients the bipolar structure of the liquid crystal within the droplets. When an electric field is applied to the dried droplets (lower left), and then increased (lower right), the liquid crystal within the droplets switches its alignment, thereby reducing the amount of light that can be scattered by the droplets when a beam is shone through them.

    2000-01-01

    Full Text Available The problems concerning the development of show caves are here considered by taking into account different aspects of the problem. A procedure to carry out an Environmental Impact Assessment (EIA has been established in the last decade and it is now currently applied. Such an assessment starts with a pre-operational phase to obtain sufficient information on the undisturbed status of a cave to be developed into a show cave. Successively a programme for its development is established with the scope to optimise the intervention on the cave at the condition that its basic environmental parameters are not irreversibly modified. The last phase of the assessment is focussed to assure a feedback through a monitoring network in order to detect any unforeseen difference or anomaly between the project and the effective situation achieved after the cave development. Some data on some of the most important show caves in the world are reported and a tentative evaluation of the economy in connection with the show caves business is eventually made.

    2002-05-01

    Laser shows and beam effects have been a source of entertainment since its first public performance May 9, 1969, at Mills College in Oakland, California. Since 1997, the Photonics Center, NgeeAnn Polytechnic, Singapore, has been using laser shows as a teaching tool. Students are able to exhibit their creative skills and learn at the same time how lasers are used in the entertainment industry. Students will acquire a number of skills including handling three- phase power supply, operation of cooling system, and laser alignment. Students also acquire an appreciation of the arts, learning about shapes and contours as they develop graphics for the shows. After holography, laser show animation provides a combination of the arts and technology. This paper aims to briefly describe how a krypton-argon laser, galvanometer scanners, a polychromatic acousto-optic modulator and related electronics are put together to develop a laser projector. The paper also describes how students are trained to make their own laser animation and beam effects with music, and at the same time have an appreciation of the operation of a Class IV laser and the handling of optical components.

    Full Text Available Background Many years of quantitative research led to our present knowledge of the symptoms and associated features (S&AF of the obstructive sleep apnoea (OSA syndrome. Aims 1. To prove that a qualitative research approach may identify symptoms and associated features of OSA in less time/effort than that used in a quantitative approach; 2. To describe the experience of patients with OSA and the effects of the syndrome on their quality of life and that of their spouses and families (issues that quantitative methods fail to recognize. Methods We used a narrative inquiry methodology (qualitative research. The sample was selected using the “snowball sampling technique". The sample included 10 patients with moderate to severe OSA who had good adherence to CPAP and significant clinical improvement after treatment, and 3 of the patient’s spouses. Results The following issues were identified: A long pre-diagnosis phase of OSA (20 years in one of the patients; Characteristic S&AF of the syndrome as experienced by patients and their spouses; The need for increased awareness of both the public and the medical establishment in regards to this disorder; Premature ejaculation (not reported previously and nightmares (non-conclusive in the literature were identified and improved with CPAP therapy. Conclusion With the use of quantitative research methods it took decades to discover things that we found in one simple qualitative study. We therefore urge scientists to use more often these qualitative methods when looking for S&AF of diseases and syndromes.

    The complex auditory brainstem response (cABR) can reflect language-based plasticity in subcortical stages of auditory processing. It is sensitive to differences between language groups as well as stimulus properties, e.g. intensity or frequency. It is also sensitive to the synchronicity of the neural population stimulated by sound, which results in increased amplitude of wave V. Finnish is a full-fledged quantity language, in which word meaning is dependent upon duration of the vowels and consonants. Previous studies have shown that Finnish speakers have enhanced behavioural sound duration discrimination ability and larger cortical mismatch negativity (MMN) to duration change compared to German and French speakers. The next step is to find out whether these enhanced duration discrimination abilities of quantity language speakers originate at the brainstem level. Since German has a complementary quantity contrast which restricts the possible patterns of short and long vowels and consonants, the current experiment compared cABR between nonmusician Finnish and German native speakers using seven short complex stimuli. Finnish speakers had a larger cABR peak amplitude than German speakers, while the peak onset latency was only affected by stimulus intensity and spectral band. The results suggest that early cABR responses are better synchronised for Finns, which could underpin the enhanced duration sensitivity of quantity language speakers. Copyright © 2016 The Authors.

    Community detection plays an important role in reflecting and understanding the topological structure of complex networks, and can be used to help mine the potential information in networks. This paper presents a Multiobjective Evolutionary Algorithm based on Affinity Propagation (APMOEA) which improves the accuracy of community detection. Firstly, APMOEA takes the method of affinity propagation (AP) to initially divide the network. To accelerate its convergence, the multiobjective evolutionary algorithm selects nondominated solutions from the preliminary partitioning results as its initial population. Secondly, the multiobjective evolutionary algorithm finds solutions approximating the true Pareto optimal front through constantly selecting nondominated solutions from the population after crossover and mutation in iterations, which overcomes the tendency of data clustering methods to fall into local optima. Finally, APMOEA uses an elitist strategy, called "external archive", to prevent degeneration during the process of searching using the multiobjective evolutionary algorithm. According to this strategy, the preliminary partitioning results obtained by AP will be archived and participate in the final selection of Pareto-optimal solutions. Experiments on benchmark test data, including both computer-generated networks and eight real-world networks, show that the proposed algorithm achieves more accurate results and has faster convergence speed compared with seven other state-of-art algorithms.

    Full Text Available Introduction: Seizure occurs in up to 10% of the population, whereas epilepsy is a chronic disease characterized by recurrent seizures that may affect up to 2% of the population. Modern neuroimaging is useful in diagnosis of  abnormalities underlying the epilepsies, but the information provided by imaging techniques can also contribute to proper classification of certain epileptic disorders and can delineate the genetics of some underlying syndromes. Neuroimaging is even more important for those patients who have medically intractable seizures. This study was carried out to establish different etiologies of seizures, to correlate the clinical data and radiological findings in cases of seizure, and to identify the common etiologies in different types of seizures.   Methods: This was a retrospective hospital-based study conducted in the Department of Radiodiagnosis of Lumbini Medical College Teaching Hospital. Records of patients of past two years, admitted in any department of the hospital with history of seizure disorder and underwent a Computed Tomography  (CT of brain were included. The CT patterns were assessed and the data were tabulated and statistically analyzed.   Results: There were a total of 480 cases out of which 263 (55% were male and 217 (45% were female with M:F ratio of 1.2:1. Generalized seizure was more frequent than partial seizure in both gender. In 274 cases of generalized seizures, CT scan findings were abnormal in 151 cases and normal finding observed in 123 cases. In 206 cases of partial seizures, 125 cases were abnormal and 81 having normal CT scan findings. Age wise distribution showed highest number (n=218 of cases in young group (60 yr. The most common cause of seizure  was  calcified granuloma (n=79, 16.5% followed by neurocysticercosis (NCC, n=64, 13%.

  1. Showing and Saying. An Aesthetic Difference

    Directory of Open Access Journals (Sweden)

    Vicente Sanfélix Vidarte

    2013-05-01

    Full Text Available Wittgenstein’s distinction between saying and showing and the associated thesis, what can be shown cannot be said, were crucial to his first philosophy, persisted throughout the evolution of his whole thought and played a key role in his views on aesthetics. The objective of art is access to the mystical, forcing us to become aware of the uniqueness of our own experience and life. When art is good is a perfect expression and the work of art becomes like a tautology. An important consequence of this understanding of art is the irreducibility of the aesthetic to the scientific perspective.

    The last European fossil occurrence of a coelacanth is from the Mid-Cretaceous of the English Chalk (Turonian, 90 million years ago). Here, we report the discovery of a coelacanth from Late Cretaceous non-marine rocks in southern France. It consists of a left angular bone showing structures that imply close phylogenetic affinities with some extinct Mawsoniidae. The closest relatives are otherwise known from Cretaceous continental deposits of southern continents and suggest that the dispersal of freshwater organisms from Africa to Europe occurred in the Late Cretaceous.

    Full Text Available Androgens play a very important role in building the skeleton in young adults and help to prevent bone loss and osteoporosis in aging men. In addition, in elderly men, bone mass has been related to estrogen levels rather than to testosterone. Estrogen replacement therapy has, therefore, been proposed to prevent bone loss in males as well as in females. Estrogen,however, has been considered as one of the hormonal risk factors of benign prostatic hyperplasia and prostate cancer and also other side effects. Young coconut juice (YCJ, presumably containing phytoestrogen, was investigated in the present study for its possible beneficial effects on delaying osteoporosis using a male rat model, to replace estrogen replacement therapy. In this study, mandibular condylar cartilage was used as the osteoporotic model. We have found that total cartilage thickness, particularly the hypertrophic zone of mandibular condylar cartilage, was thickest in the sham-operated rats receiving YCJ orally fed for a 14-day period, compared with a sham orchidectomized, orchidectomized rats receiving estradiol benzoate, and orchidectomized rats receiving YCJ.

    Full Text Available Poverty should be defined, measured, and scrutinized its root causes from a multi-dimension perspectives. Therefore, in designing and implementation of poverty alleviation program, it should consider economic factors, social and political contexts surrounding the poor. Sen (1982; 1999 views poverty as a multifaceted world and ethical dimension essentially should be placed underpinning it as a vital economic problem. The paper takes the stance that the poor themselves have potential capacity to alleviate their condition in resolving poverty trap. Community development program is one of the strategies to deal with the poverty problem. Islamic microfinance can play an important role in combating poverty dilemma especially in Muslim majority population communities. Through the approach proposed by Bigg and Satterthwaite (2005 with strengthening local organizations and community development programs, Islamic microfinance should engage a strategic partnership with the Masjid and Islamic charity institutions (zakat and waqf organization. This strategic alliance will result more integrated programs and also capacity building of the institutions involved. This paper aims to contribute a grass root model in the purpose of combating poverty in the framework of Islamic economic system. =========================================== Kemiskinan harus didefinisikan, diukur, dan diteliti akar penyebabnya dari berbagai perspektif.

  5. Characterizing Fractures Across the Astronaut Corps: Preliminary Findings from Population-Level Analysis

    2017-01-01

    Despite evidence of bone loss during spaceflight and operational countermeasures to mitigate this loss, the subsequent risk of fracture among astronauts is not known. The physiologic process of diminished bone density and bone recovery during or following spaceflight is multifactorial. Such factors as age, sex, fracture history, and others may combine to increase fracture risk among astronauts. As part of the 2016 Bone Research and Clinical Advisory Panel (RCAP), the authors analyzed data collected on 338 NASA astronauts to describe the demographics, bone-relevant characteristics, and fracture history of the astronaut population. The majority of the population are male (n=286, 84.6%), have flown at least one mission (n=306, 90.5%), and were between the ages of 30 and 49 at first mission (n=296, 96.7% of those with at least one mission). Of the 338 astronauts, 241 (71.3%) experienced a fracture over the course of their lifetime. One hundred and five (43.5%) of these 241 astronauts only experienced a fracture prior to being selected into the Astronaut Corps, whereas 53 (22.0%) only experienced a fracture after selection as an astronaut. An additional 80 astronauts (33.2%) had both pre- and post-selection fractures. The remaining 3 astronauts had a fracture of unknown date, which could not be categorized as pre- or post-selection. Among the 133 astronauts with at least one post-selection fracture, males comprised 90.2% (n=120) compared to 84.5% of the entire Corps, and females accounted for 9.8% (n=13) compared to 15.4% of the Corps. Ninety-seven of the 133 astronauts with post-selection fractures (72.9%) had one fracture event, 22 (16.5%) had two fractures, and 14 (10.5%) had three or more fractures. Some astronauts with multiple fractures suffered these in a single event, such as an automobile accident. The 133 astronauts with a post-selection fracture accounted for a total of 188 fracture events. One hundred and four (78.2%) of astronauts with post-selection fractures experienced those fractures following their first mission (mean 12.7 +/- 11.1 years following first mission; range 14.0 days - 50.6 years). Additional analyses are ongoing and include examination of fracture history, skeletal site, mechanism, and type of fracture, age at time of fracture, time from spaceflight to fracture, as well as multivariable analysis comparing fracture events to non-events. The results of such analyses may reveal trends in risk factors for fracture among the astronaut corps that have yet to be systematically described through a corps-wide approach.

    Pretorius, Chrisma

    2016-05-01

    This qualitative study aimed at examining the subjective experiences of patients during the complicated and often prolonged diagnostic process of psychogenic non-epileptic seizures (PNES). Thematic analyses were used to explore the semi-structured interviews that were conducted with ten individuals who have been diagnosed with PNES. Six main themes, namely inexpert healthcare providers, limited medical insurance and loss of independence were identified as barriers, while social support, comprehensive medical insurance and knowledgeable healthcare providers were identified as facilitators through the process of thematic analysis. The patients' perspectives revealed that an earlier diagnosis of PNES is essential to address the loss of independence and limit inappropriate and potentially harmful treatment as well as the costly burden of this condition on both the patient and the healthcare system. It was evident in this study that healthcare providers play an essential role in the subjective experiences of these individuals during the diagnostic process. The implementation of continuous education programmes for healthcare providers in particular could contribute positively to the diagnostic process of PNES for patients.

    The aim of the study was to evaluate mental distress and health-related quality of life in patients with bilateral partial deafness (high-frequency sensorineural hearing loss) before cochlear implantation, with respect to their audiological performance and time of onset of the hearing impairment. Thirty-one patients and 31 normal-hearing individuals were administered the Beck Depression Inventory (BDI), the State-Trait-Anxiety-Inventory (STAI) and the World Health Organization Quality of Life-BREF questionnaire (WHOQOL-BREF). Patients also completed the Nijmegen-Cochlear-Implant-Questionnaire (NCIQ), a tool for evaluation of quality of life related to hearing loss. Patients revealed increased depressive and anxiety symptoms, as well as decreased health-related quality of life (psychological health, physical health), in comparison with their healthy counterparts (t tests, p patients with a prelingual onset of hearing loss enhanced self-evaluated social interactions and activity (NCIQ), when their outcomes were contrasted with those obtained in individuals with postlingual partial deafness (p Patients not using hearing aids had better audiological performance and, therefore, better sound perception and speech production, as measured with NCIQ. There was no effect of hearing aid use with respect to mental distress. Additional statistically significant correlations seen in patients included those between a steeper slope hearing loss configuration (averaged pure-tone thresholds at 1 and 2 kHz with subtracted threshold at 0.5 kHz) and better audiometric speech detection, between audiometric thresholds and the subjectively rated sound perception (NCIQ), as well as left-ear audiometric word recognition scores and the subjectively perceived ability to recognize advanced sounds (NCIQ). In addition, a longer duration of postlingual deafness, as well as a younger age at the onset were both related to worse speech detection thresholds. The results of the study provide evidence that successful rehabilitation in patients with partial deafness might have to go beyond the standard speech therapy. Enhancement of the regular diagnostic assessment with additional psychological tools is highly recommended. Further investigation is required as to the role of functional residual hearing, hearing aid use and tinnitus, in relation to future outcomes of cochlear implantation.

    Full Text Available Abstract Background There is still much debate about the best adjuvant therapy after surgery for endometrial cancer (EC and there are no current guidelines. Radiotherapy (RT alone does not seem to improve overall survival. We investigated whether concomitant Paclitaxel (P and RT gave better clinical results. Methods Twenty-three patients with high-risk EC (stage IIB, IIIA, IIIC or IC G3 without lymphadenectomy or with aneuploid tumor underwent primary surgery and were then referred for adjuvant therapy. P was given at a dose of 60 mg/m2 once weekly for five weeks during RT, which consisted of a total radiation dose of 50.4 Gy. Three further weekly cycles of P at a dose of 80 mg/m2 were given at the end of RT. Overall survival and disease-free survival were calculated from the time of surgery. Patterns of failure were recorded by the sites of failure. Results A total of 157 cycles of P were administered both during radiotherapy and consolidation chemotherapy. Relapses occurred in five patients (21.7%. Median time to recurrence was 18.6 months (range 3–28. Survival rate for all the patients was 78.2%. Overall survival for the patients who completed chemo-radiation was of 81%. In this group median time to recurrence was 19.2 months (range 3–28. All recurrences were outside the radiation field. Mortality rate was 14.2%. Conclusion This small series demonstrates pelvic radiotherapy in combination with weakly P followed by three consolidation chemotherapy cycles as an effective combined approach in high risk endometrial carcinoma patients.

    Recent advances in hemophilia prophylaxis have raised the need for accurate noninvasive methods for assessment of early cartilage damage in maturing joints to guide initiation of prophylaxis. Such methods can either be semiquantitative or quantitative. Whereas semiquantitative scores are less time-consuming to be performed than quantitative methods, they are prone to subjective interpretation. To test the feasibility of a manual segmentation and a quantitative methodology for cross-sectional evaluation of articular cartilage status in growing ankles of children with blood-induced arthritis, as compared with a semiquantitative scoring system and clinical-radiographic constructs. Twelve boys, 11 with hemophilia (A, n = 9; B, n = 2) and 1 with von Willebrand disease (median age: 13; range: 6-17), underwent physical examination and MRI at 1.5 T. Two radiologists semiquantitatively scored the MRIs for cartilage pathology (surface erosions, cartilage loss) with blinding to clinical information. An experienced operator applied a validated quantitative 3-D MRI method to determine the percentage area of denuded bone (dAB) and the cartilage thickness (ThCtAB) in the joints' MRIs. Quantitative and semiquantitative MRI methods and clinical-radiographic constructs (Hemophilia Joint Health Score [HJHS], Pettersson radiograph scores) were compared. Moderate correlations were noted between erosions and dAB (r = 0.62, P = 0.03) in the talus but not in the distal tibia (P > 0.05). Whereas substantial to high correlations (r range: 0.70-0.94, P < 0.05) were observed between erosions, cartilage loss, HJHS and Pettersson scores both at the distal tibia and talus levels, moderate/borderline substantial (r range: 0.55-0.61, P < 0.05) correlations were noted between dAB/ThCtAB and clinical-radiographic constructs. Whereas the semiquantitative method of assessing cartilage status is closely associated with clinical-radiographic scores in cross-sectional studies of blood-induced arthropathy, quantitative measures provide independent information and are therefore less applicable for that research design.

    2016-09-01

    Approximately 10 % of first year medical students have clinically relevant anxiety or depression which may affect academic success and quality of life. This study tested the effects of a stress management intervention on indicators of anxiety, depression and self-efficacy in self-selected first year medical students. Forty two medical students volunteered to participate and provided informed consent. An eight session intervention was offered and focused on building relaxation skills, adaptive coping, and basic nutrition. Anxiety, depression, and self-efficacy were assessed pre and post intervention. This group of students had significantly higher baseline values of depression and anxiety but lower self-efficacy compared to a previous study of medical students at the same institution (p students were at risk for later clinical syndromes. Intervention directed to decreasing the effects of stress was associated with improvement in indicators of distress and may modify the longer term risk.

    Vargas-Aburto, Carlos

    1997-01-01

    The objective of the photovoltaic (PV) cell calibration experiment for Pathfinder was to develop an experiment compatible with an ultralight UAV to predict the performance of PV cells at AM0, the solar spectrum in space, using the Langley plot technique. The Langley plot is a valuable technique for this purpose and requires accurate measurements of air mass (pressure), cell temperature, solar irradiance, and current-voltage(IV) characteristics with the cells directed normal to the direct ray of the sun. Pathfinder's mission objective (95-3) of 65,000 ft. maximum altitude, is ideal for performing the Langley plot measurements. Miniaturization of electronic data acquisition equipment enabled the design and construction of an accurate and light weight measurement system that meets Pathfinder's low payload weight requirements.

    Mahan, Shannon; Martin, Frederick; Taylor, Cathy

    2015-01-01

    The Upton Chamber in Massachusetts, an earth-covered stone structure 3.4 meters (m) in diameter, with a corbelled stone dome, and a 4.3 m long entrance passageway, is studied with the aim of determining whether optically stimulated luminescence (OSL) dating methods can be used to establish the approximate construction date of the entranceway. Three samples, taken from soil behind the lowest stones in the wall of the entrance passageway, returned OSL ages between 385 and 660 years ago (or from 1625 A.D. to 1350 A.D.; using the year 2011 as the 0 year). One sample, taken below the bottom of the artifact layers in an archeological test pit in front of the chamber entrance, returned OSL ages between 650 and 880 years ago. A modern sample collected from a nearby fluvial channel returned an age between 55 and 175 years. The Upton Chamber OSL sampling results are challenging to interpret because there are mixtures in the samples of both younger and older grains that likely result from human modification, root or soil processes, animal bioturbation (i.e. ants and worms), and/or partial bleaching. The ages were determined using the lowest component of the finite mixture model as applied to a distribution of quartz grains. Further research may enable us to determine whether older components are of anthropomorphic or geological origin.

    Objectives Functional losses are common in healthy and cognitively impaired older adults. However, subtle declines in instrumental activities of daily living (IADLs) are not always detected in self-reports. Performance IADL measurements are financially and time burdensome, restricting their use in varied settings. To address these limitations, we developed the Brief Everyday Activities Measure (BEAM), a short (speed. Conclusions Medication and finance management can be efficiently assessed within five minutes. The BEAM may be a valuable screening tool to evaluate these functional abilities. PMID:26482695

    Currently, the cosmetics industry relies on the results of in vitro genotoxicity tests to assess the safety of chemicals. Although the cytokinesis-block micronucleus (CBMN) test for the detection of cells that have divided once is routinely used and currently accepted by regulatory agencies, it has some limitations. Reconstituted human epidermis (RHE) is widely used in safety assessments because its physiological properties resemble those of the skin, and because it allows testing of substances such as hydrophobic compounds. Thus, the micronucleus test is being adapted for application in RHE-reconstructed tissues. Here we investigated whether two different reconstructed epidermis models (EPI/001 from Straticell, and RHE/S/17 from Skinethic) are suitable for application of the micronucleus test. We found that acetone does not modify micronucleus frequency, cell viability, and model structure, compared with non-treated RHE. Treatment of the EPI/001 model with mitomycin C and vinblastine resulted in a dose-dependent increase of micronucleus frequency as well as a decrease of tissue viability and of binucleated cell rate, while no changes of the epidermal structure were observed. The number of binucleated cells obtained with the RHE/S/17 model was too small to permit micronucleus testing. These results indicate that the proliferative rate of the tissue used is a critical parameter in performing the micronucleus test on a 3D model.

    Goldman, Suzanne E; Wang, Lily; Fawkes, Diane B

    2014-02-24

    Sleep problems are common in children with autism spectrum disorder (ASD) and are often associated with problem behaviors. Problematic sleep in the child may impact maternal sleep. We examined the association of sleep in mother-child dyads to child daytime behavior and maternal insomnia and daytime sleepiness in 11 children with ASD and 6 children of typical development (TD) using wrist actigraphs over 14 consecutive nights. Early morning wakenings were significantly associated with poorer daytime behavior as measured by the Child Behavior Checklist in both ASD and TD children. Additionally, associations were found between mother and child sleep and between the child's sleep and maternal daytime sleepiness. These results highlight the need to consider the potential interaction of maternal-child sleep in future studies.

    2011-03-24

    Emotional-motivational dysfunctions may significantly contribute to symptoms of attention-deficit/hyperactivity disorder (ADHD). Hyperactive-impulsive symptoms and sensation seeking could be the result of a search for reinforcers, and cognitive dysfunctions might be due to a low motivational drive. Emotional-motivational dysfunctions could also explain social dysfunctions in ADHD patients because they may lead to misinterpretations of emotional and social clues. Since methylphenidate (MPH) is the first choice as a pharmacological treatment in ADHD, we examined its influence on dysfunctional emotional processes. 13 adult ADHD patients were examined twice, without and after intake of MPH according to their personal medication regimen. The affect-modulated startle paradigm was used to assess physiological (affect-modulated startle response) and subjective (valence and arousal ratings) responses to pleasant, neutral and unpleasant visual stimuli. Healthy controls displayed affective startle modulation as expected, with startle attenuation and potentiation while watching pleasant and unpleasant pictures, respectively. In contrast, unmedicated ADHD patients displayed deficient responses to pleasant stimuli; no startle attenuation during the exposure to pleasant pictures was observed. However, MPH reinstated a normal affective startle modulation, as indicated by attenuation and potentiation associated with pleasant and unpleasant pictures, respectively. Valence and arousal ratings of patients were not affected by MPH. The data suggest that MPH as first choice treatment in ADHD has a positive impact on emotional processes in adult ADHD patients and points to the clinical relevance of emotional-dysfunctions in ADHD.

    Full Text Available Introduction Fishing, one of the oldest productive activities, is an important sector of the national and world economy. Aim To evaluate the vestibular behavior in a population of fishermen. Methods In a retrospective and cross-sectional study, 13 fishermen (mean 45.0, between 33 and 62 years of age, were submitted to anamnesis, otorhinolaryngological evaluation, and vestibular exam through the vector electronystagmography. Results The most evident otoneurologic symptoms were hearing loss (76.9%, tinnitus (61.7%, dizziness (46.1%, and headache (46.1%. The most evident clinical symptoms were fatigue (46.1%, depression (23.0%, anxiety (15.3%, insomnia (7.7%, and agitation during sleep (7.7%. There were alterations in the vestibular exam in 5 fishermen (38.5% discovered in the caloric test. There was a prevalence of alteration in the peripheral vestibular system. There was a major frequency of the peripheral vestibular irritative syndrome. Conclusion The otoneurologic complaints were frequent in the population studied to verify the importance of allowing labyrinth exams and the need for adopting preventive measures relating to noise exposure as well as carbon monoxide exposure, because they can cause and/or enhance various manifestations of labyrinthine vestibular impairment that can affect the quality of life of these workers.

    Experience sampling is a powerful method for obtaining ecologically valid data from research participants in real-world contexts. Given the urgent need for innovative and sensitive outcome measures in autism spectrum disorder (ASD) research, the present study sought to examine the feasibility of using experience sampling of positive affect and behavior in adolescents with ASD. Nineteen high functioning adolescents with ASD and 20 sex and age matched controls completed smartphone- and Qualtrics® -based experience sampling of positive affect and behavior six times over four days. Adherence was excellent: adolescents with ASD completed 85% of the assessments, compared to 93% in controls, and response rates were not impacted by age or IQ. Groups did not differ in positive affect overall or as a function of activities, nor did groups differ in the proportion of assessments completed during social or nonsocial activities. However, groups did differ in the proportion of assessments completed during preferred activities. Results suggest that smartphone- and Qualtrics® -based experience sampling with high functioning adolescents with ASD is feasible and captures real-world behaviors that would not be possible using laboratory-based measures.

    1998-07-01

    The authors explored the family history and psychiatric comorbidity of a group of compulsive buyers who volunteered for medication studies. Compulsive buying is characterized by inappropriate shopping and spending behavior that leads to impairment. Thirty-three subjects who met the criteria of McElroy and colleagues for compulsive buying, and who scored more than two standard deviations above the mean on the Compulsive Buying Scale, were recruited. Twenty-two comparison subjects were recruited in the course of another study, and the presence of obsessive-compulsive disorder was the only reason for exclusion. Both groups were administered the Structured Clinical Interview for DSM-III-R disorders. The Family History Research Diagnostic Criteria were used to collect information about psychiatric disorders in first-degree relatives. Compulsive buyers had a mean age of 40 years; two (6%) were men. Comparison subjects had a mean age of 39 years; six (27%) were men. The two groups differed in gender distribution but not in age, marital status, or educational achievement. Compulsive buyers were more likely than comparison subjects to have lifetime mood disorders (especially major depression) and to have more than one psychiatric disorder. First-degree relatives of compulsive buyers were more likely than comparison relatives to suffer from depression, alcoholism, and a drug use disorder and to suffer more psychiatric disorders in general. These results indicate that persons who report compulsive buying behavior, and their first-degree relatives, are more likely to have a higher prevalence of psychiatric disorder than are comparison subjects.

    The assessment of language skills in early childhood can provide important information about the future of literacy and academic performances. Children with reading difficulties should be identified early in their education, before they suffer from shortcomings and experience failures and feel discouraged at school. Considering the importance of early identification of language disorders and the shortage of standardized instruments for the Brazilian scenario, the overall objective of this study was to translate and adapt the Dyslexia Early Screening Test - Second Edition (DEST-2) to, subsequently, verify its applicability and efficacy in preschoolers who had Brazilian Portuguese as their native language. The study was composed of 20 children of both genders, regularly enrolled in a public school in the metropolitan region of São Paulo, none had any complaints related to learning and no indicators of sensory, neurological, cognitive, or behavioral disorders. It was observed that there was no need for significant changes to the original structure of the DEST-2 or in their administration instructions format. The performance of the children in the translated and in the national exams that were used as a benchmark was compatible, suggesting that the adjustments made met the equivalences needed to utilize this instrument with Brazilian children. A randomized study that will complement the preliminarily data obtained is in progress. Taking into consideration the linguistic and cultural diversity of Brazil, it is imperative that the translated version of the DEST-2 can be applied on a large scale and in several states of the country, in order to allow the use of this instrument as a language assessment tool in Brazil.

  11. Redevelopment of essential hypertension after cessation of long term therapy; preliminary findings.

    Science.gov (United States)

    1984-01-01

    We have previously found that the vascular hypertrophy that accounts for the maintenance of a substantial fraction of the elevation of the total peripheral resistance index (TPRI) in essential hypertension can be almost completely reversed by one years antihypertensive treatment (1). On ceasing treatment, blood pressure returns rapidly to pretreatment values suggesting that the original cause of the hypertension is still present. In the present study, 7 patients stopped a standard regimen for 10 weeks after at least 2 years of normotension. In the first week, standing and lying blood pressure increased related to rise in supine cardiac index and TPRI. Thereafter standing pressures, supine systolic blood pressure and cardiac index (CI) increased further, but supine diastolic blood pressure and TPRI did not alter. Changes in measurements of resting sympathetic activity, plasma volume or renin-angiotensin did not account for these observations. The return of hypertension after stopping effective therapy has some features previously described in borderline hypertension, particularly increasing systolic blood pressure, CI and postural blood pressure responses. Some of the changes may reflect the relative preponderance of cardiac and vascular amplifiers.

    2015-01-01

    NASA and the National Center for Atmospheric Research have developed an icing remote sensing technology that has demonstrated skill at detecting and classifying icing hazards in a vertical column above an instrumented ground station. This technology has recently been extended to provide volumetric coverage surrounding an airport. Building on the existing vertical pointing system, the new method for providing volumetric coverage will utilize a vertical pointing cloud radar, a multifrequency microwave radiometer with azimuth and elevation pointing, and a NEXRAD radar. The new terminal area icing remote sensing system processes the data streams from these instruments to derive temperature, liquid water content, and cloud droplet size for each examined point in space. These data are then combined to ultimately provide icing hazard classification along defined approach paths into an airport.

    2010-12-01

    As part of the planning process for a larger survey study to examine factors affecting employers' intention to hire and hiring of people with disabilities, a series of three semi-structured focus groups were held with key hiring decision makers, such as Human Resources directors, Chief Operating Officers (COOs), or Chief Executive Officers (CEOs) of small, medium, and large Seattle area companies. The chief goals of the focus groups were to elicit and refine the participants' beliefs, normative influences, and perceived control relative to hiring workers with disabilities. Narrative data obtained from the focus group discussion were examined using the Theory of Planned Behavior (TPB) to identify themes expressed by the focus group participants within the context of company size. Themes did vary by company size, but a prevailing concern across all companies related to questions about the efficiency/effectiveness of contact with vocational rehabilitation agencies. For both small- and mid-sized companies, there was a belief that people with disabilities could not do the work or were somehow less qualified. For large companies, convincing departmental and team managers that outreaching workers with disabilities would be a worthwhile hiring practice remained a challenge. The themes derived from this study can be used to help occupational rehabilitation professionals develop educational and marketing interventions to improve employers' attitudes toward hiring and retaining individuals with disabilities.

    The Orchid flora of Madagascar is one of the most diverse with nearly 1000 orchid taxa, of which about 90% are endemic to this biodiversity hotspot. The Itremo Massif in the Central Highlands of Madagascar with a Highland Subtropical climate range encompasses montane grassland, igneous and metamorphic rock outcrops, and gallery and tapia forests. Our study focused on identifying culturable mycorrhizae from epiphytic, lithophytic, and terrestrial orchid taxa to understand their diversity and density in a spatial matrix that is within the protected areas. We have collected both juvenile and mature roots from 41 orchid taxa for isolating their orchid mycorrhizal fungi (OMF), and to culture, identify, and store in liquid nitrogen for future studies. Twelve operational taxonomic units (OTUs), of three known orchid mycorrhizal genera, were recognized by analysis of internal transcribed spacer (ITS) sequences of 85 isolates, and, by comparing with GenBank database entries, each OTU was shown to have closely related fungi that were also found as orchid associates. Orchid and fungal diversity were greater in gallery forests and open grasslands, which is very significant for future studies and orchid conservation. As far as we know, this is the first ever report of detailed identification of mycorrhizal fungi from Madagascar. This study will help start to develop a programme for identifying fungal symbionts from this unique biodiversity hotspot, which is undergoing rapid ecosystem damage and species loss. The diversity of culturable fungal associates, their density, and distribution within the Itremo orchid hotspot areas will be discussed.

    2015-07-01

    Full Text Available e-commerce, especially e-retail, has changed the concept of marketing and business in developed countries, where the customer does not need to go to the market to get the goods. This process is not yet successful in Arabian countries, particularly Saudi Arabia. This study aims to identify the most important obstacles that prevent enterprises from providing electronic sales to their customers. I found that 86% of facilities do not provide these services. The most important obstacles that prevented them doing so are the inefficient laws and electronic payment systems, in addition to the lack of awareness and confidence of consumers in these services.Upon conducting a survey, we estimate that 86% of businesses do not provide these services. The biggest obstacles in the provision of these services are the inefficient and deficient laws and inapt electronic payment systems. In addition there is a lack of awareness and confidence amongst consumers in relation to these services

    The "Javanese factor" is a strategic consideration in Indonesian electoral politics, as the Javanese are Indonesia's most numerous inhabitants. However, seminal masterpieces such as those by Geertz (1960) and Gaffar (1992) apply only a limited and individual-based voting approach in their efforts to explain Javanese voting behavior. Recent qualitative case studies explore anut grubyuk (fitting in) as a unique form of grouped rural Javanese voting behavior, rooted in the Javanese communal phil...

    Impaired autonomic function is common in the acute poststroke phase but little is known about its effects on functional outcome after acute ischemic stroke. This study sought to investigate the impact of autonomic dysfunction by Ewing's classification on functional outcome 2 months after acute ischemic stroke. 34 consecutive acute ischemic stroke patients within 7 days after onset were enrolled. On admission, autonomic function was assessed by Ewing's battery tests. Stroke severity was assessed by the National Institutes of Health Stroke Scale (NIHSS), autonomy in activities of daily living by the Barthel Index (BI), and global disability by the modified Rankin Scale (mRS). BI and mRS were also evaluated 2 months after ischemic stroke onset. On admission, eight patients were diagnosed as minor autonomic dysfunction and 26 patients as relatively severe autonomic dysfunction. The prevalence of relatively severe autonomic dysfunction in ischemic stroke patients was 76.5%. There were no significant differences in baseline characteristics between the minor and severe autonomic dysfunction groups. 2 months after stroke onset, the mean BI score of patients with minor autonomic dysfunction and severe autonomic dysfunction increased from 76.3±15.3 on admission to 95.0±7.1, 66.5±15.2 on admission to 74.8±15.9 respectively. The mean BI score after 2-month stroke onset and the change in BI from admission to 2-month outcome (delta BI) in patients with severe autonomic dysfunction were lower than those in patients with minor autonomic dysfunction (all Pacute stroke patients. Relatively severe autonomic dysfunction is related to an unfavorable functional outcome in patients with acute ischemic stroke. Copyright © 2011 Elsevier B.V. All rights reserved.

    This study aimed to describe a novel strategy to determine the traction forces needed to reproduce physiologic uterine displacement in women with and without prolapse. Participants underwent dynamic stress magnetic resonance imaging (MRI) testing as part of a study examining apical uterine support. Physiologic uterine displacement was determined by analyzing uterine location in images taken at rest and at maximal Valsalva. Force-displacement curves were calculated based on intraoperative cervical traction testing. The intraoperative force required to achieve the uterine displacement measured during MRI was then estimated from these curves. Women were categorized into three groups based on pelvic organ support: group 1 (normal apical and vaginal support), group 2 (normal apical support but vaginal prolapse present), and group 3 (apical prolapse). Data from 19 women were analyzed: five in group 1, five in group 2, and nine in group 3. Groups were similar in terms of age, body mass index (BMI), and parity. Median operating room (OR) force required for uterine displacement measured during MRI was 0.8 N [interquartile range (IQR) 0.62-3.22], and apical ligament stiffness determined using MRI uterine displacement was 0.04 N/mm (IQR 0.02-0.08); differences between groups were nonsignificant. Uterine locations determined at rest and during maximal traction were lower in the OR compared with MRI in all groups. Using this investigative strategy, we determined that only 0.8 N of traction force in the OR was required to achieve maximal physiologic uterine displacement seen during dynamic (maximal Valsalva) MRI testing, regardless of the presence or absence of prolapse.

[University College London Hospitals NHS Trust, Centre for Respiratory Diseases, London (United Kingdom)

    2011-12-15

    It has recently been recognized that PET/CT may play a role in diffuse parenchymal lung disease. However, interpretation can be confounded due to the variability in lung density both within and between individuals. To address this issue a novel correction method is proposed. A CT scan acquired during shallow breathing is registered to a PET study and smoothed so as to match the PET resolution. This is used to derive voxel-based tissue fraction correction factors for the individual. The method was evaluated in a lung phantom study in which the lung was simulated by a Styrofoam/water mixture. The method was further evaluated using {sup 18}F-FDG in 12 subjects free from pulmonary disease where ranges before and after correction were considered. Correction resulted in similar activity concentrations for the lung and background regions, consistent with the experimental phantom set-up. Correction resulted in reduced inter- and intrasubject variability in the estimated SUV. The possible application of the method was further demonstrated in five subjects with interstitial lung changes where increased SUV was demonstrated. Single study pre- and post-treatment studies were also analysed to further illustrate the utility of the method. The proposed tissue fraction correction method is a promising technique to account for variability of density in interpreting lung PET studies. (orig.)

    Full Text Available Siberian ibex ( Capra sibirica remain poorly understood, as little is known about their ecology . W e began studying ibex in Ikh Nart Nature Reserve, Dornogobi Aimag, Mongolia to better understand the species’ ecological needs and threats. In this paper we report on home range and core range sizes. We captured 27 ibex and fi t them with radio telemetry collars using drive nets for adults and juveniles ( n = 22 and hand captures for neonatal kids ( n = 5 . W e collected 1,029 locations from September 2003 to February 2007. Throughout the study, 9 ibex with 40+ fi xe s used mean, annual home range sizes of 3,115.5 ± 504.2 ha using the Minimum Convex Polygon method. Home ranges calculated using the fi xe d kernel method were smaller: 475.9 ± 14.7 ha for 50% kernel and 1,808.0 ± 88.1 ha for 95% kernel. Ibex from different demographic groups (males vs. females and juveniles vs. adults used remarkably similar home and core ranges; we found no signifi ca nt differences among any demographic groups. Although not quantifi ed , ibex mostly restricted their activities to areas with steep cliffs and rocky outcrops and home ranges overlapped extensively.

  15. Single case methodology in neurobehavioural rehabilitation: preliminary findings on biofeedback in the treatment of challenging behaviour.

    Science.gov (United States)

    O'Neill, Brian; Findlay, Gemma

    2014-01-01

    The use of single-case methodology (SCM) in brain injury rehabilitation is described and contrasted with other methodologies. SCM is optimal when attempting to meet highly individual presentations or to trial innovative solutions. Portable biofeedback is a potentially effective means of helping persons with brain injury to recognise and regulate emotional states. Emotional dysregulation, associated with disinhibition on tests of executive function, is hypothesised to underpin aggressive challenging behaviour and may be amenable to feedback on heart rate variability, a marker for stress. Two case studies of a novel biofeedback intervention, emWave2, to address aggression directed towards the self and towards others are presented. Data from two A-B designs were analysed using the non-overlap all pairs (NAP) statistical method. Clinical significance of outcome is reported in both cases but only Case 2 reached statistical significance. The discussion highlights limitations of the methodology. Results are discussed in relation to the device helping participants differentiate the physiological state associated with stress. The future application of wearable physiological sensing and feedback systems is explored.

    2009-06-15

    Normal and degenerated cartilages have different magnetic resonance (MR) capillary permeability (K{sup trans}) and interstitial interchangeable volume (v{sub e}). Our hypothesis was that glucosamine sulfate treatment modifies these neovascularity abnormalities in osteoarthritis. Sixteen patients with patella degeneration, randomly distributed into glucosamine or control groups, underwent two 1.5-Tesla dynamic contrast-enhanced MR imaging studies (treatment initiation and after 6 months). The pain visual analog scale (VAS) and American Knee Society (AKS) score were used. A two-compartment pharmacokinetic model was used. Percentages of variations (postreatment-pretreatment/pretreatment) were compared (t-test for independent data). In the glucosamine group, pain and functional outcomes statistically improved (VAS: 7.3 {+-} 1.1 to 3.6 {+-} 1.3, p < 0.001; AKS: 18.6 {+-} 6.9 to 42.9 {+-} 2.7, p < 0.01). Glucosamine significantly increased K{sup trans} at 6 months (-54.4 {+-} 21.2% vs 126.7 {+-} 56.9%, p < 0.001, control vs glucosamine). In conclusion, glucosamine sulfate decreases pain while improving functional outcome in patients with cartilage degeneration. Glucosamine sulfate increases K{sup trans}, allowing its proposal as a surrogate imaging biomarker after 6 months of treatment. (orig.)
