Objective To explore the clinicopathological features of non-familial colorectal cancer with high-frequency microsatellite instability (MSI-H). Methods One hundred and fifty patients with colorectal cancer who had no family history were enrolled in this study from June 2006 to June 2008. Five standard microsatellite loci including BAT25, BAT26, D2S123, D5S346, and D17S250 were amplified with immunofluorescent polymerase chain reaction. The patient information including age, sex, and tumor location was recorded. Pathological features including differentiation, mucinous differentiation, histological heterogeneity, and Crohn's-like reaction were observed under light microscope. The presence of tumor-infiltrating lymphocytes (TLs, CD4+ and CD8+) was detected by means of immunohistochemistry. A regression equation was obtained by stepwise logistic regression analysis to evaluate the relationship between MSI-H phenotype in colorectal cancer ands pathological features. Results MSI-H phenotype occurred in 13.33% of the 150 patients with non-familial colorectal cancer. Poor differentiation, histological heterogeneity, Crohn's-like reaction, and presence of TLs were found to be independent factors to identify MSI-H non-familial colorectal cancer. Logistic regression equation showed an overall sensitivity of 70.0%, specificity of 99.2%, and accuracy of 95.3% in identifying MSI-H non-familial colorectal cancer. Conclusion MSI-H non-familial colorectal cancer manifests specific pathological features, which may be relied upon for effective identification of that disease. 展开更多

Background: The parent-to-child influences can be adaptive and contribute to the optimal psychological well-being and positive perception of the athlete. Contrary to the healthy parental involvement, a family can also have negative effects on an athlete development. The purpose of this study was to determine gender, father involvement, and mother involvement differences in the psychological profiles of collegiate freshmen athletes as measured by perfectionism, physical self-concept, and psychological well-being. Methods: Eighty-two male and 73 female collegiate freshmen responded to self-reported measures of family involvement, perfectionism, physical self-concept, and psychological well-being. Three separate 2 x 2 x 2 (gender x mother involvement x father involvement) factorial multivariate analysis of variance (MANOVAs) were carried out on the respective subscales from the reported measures. Results: There were significant differences for gender as well as father involvement in perfectionism (p 〈 0.01). Freshmen females had lower concern over mistakes, and greater levels of organization as well as planfulness than males. Furthermore, freshmen athletes with high involved fathers showed greater levels of high standards for others as well as organization. Conclusion: Father involvement and mother involvement impact perfectionism, physical self-concept, and psychological well-being. perspective. extends through the freshmen year in college as shown in the athletes' Future research should develop better measures and utilize a family systems Copyright @ 2012, Shanghai University of Sport.

As a study in art history critical theory, this paper looks at the appreciation and usage of art amongst interest groups at the time of the Great War and the subsequent legacy of the work of Canada's resident war artist Richard Jack. The Canadian War Museum's recent web page described Jack's standing officer in The Second Battle of Ypres 22 April to 25 May 1915 as one who "exemplifies the courage and resolve of the inexperienced Canadians in their first major battle". This comment showed a marked contrast to the contemporary art critic Richard Cork who described the first of the Canadian war memorials paintings as "a clich6-ridden bandaged officer ... shamelessly catering to public sentiment". Given these disparate positions, the author attempts to explain the gulf between these points of view and subsequently make the case that art has a broad application that might make us cautious of viewing a given work without due consideration of the context of its making and future merits. 展开更多

The paper presents findings of an empirical study carried out in an Italian area and focused on the effects of the economic crisis on immigrant families: the goal was to identify how the difficulties of these years (not only socio-economic but also in terms of negative attitudes toward immigrants) affect on the life-paths of second generations. What happens to their school career? Are they forced to leave school in order to improve the family's income? Are they sent back to the country of origin of their parents to reduce life-costs in the immigration country? Thanks to a collection of around 30 interviews with young people between 18-24 years old and 30 interviews with both parents and social workers, the strategies which families are choosing to face economic and labour difficulties and their effects on integration paths and inter-ethnic relations will be described. 展开更多

In November 2015, they were 10,952. This research focuses on their foster care and examines the point of view of social workers that have theoretical competences and fieldwork. The main objective of this paper is to present operational recommendations concerning the definition and organization of this instrument, starting from social workers' direct experiences. Main results: A friendly familiar setting is useful to overcome loneliness and social isolation coming from a new and unknown realiW during adolescence and permit a better social, school, and professional integration for the minor compared with residential care. For a successful outcome, the strengths consist in: The young migrant must not have behavioral nor psychiatric disorders and must be willing to integrate himself into a new family, recognize adult authoriW and share his life plan with family's adults; training all foster families included omo-cultural ones; the birth family involvement in the foster care's project. The ascertained criticalities concern on the low number of available families, the lack of standard operating procedures, guidelines, research, and literature on the topic. 展开更多

Hendra virus,a novel member of the family Paramyxovirus that has emerged from bats in Australia,causes fatal disease in livestock and humans. Eleven spillover events have been identified since the first description of the virus in 1994,resulting in a total of 37 equine cases and six human cases. All human cases have been attributed to exposure to infected horses;there is no evidence of bat-to-human or human-to-human transmission. Low infectivity and a high case fatality rate are features of Hendra virus infection in both horses and humans. The temporal pattern of spillover events suggests seasonal factors(plausibly be environmental,biological or ecological) as the proximate triggers for spillover. Minimisation of the future occurrence and impact of Hendra virus infections requires an understanding of the ecology of flying foxes,of virus infection dynamics in flying foxes,and of the factors that promote spillover. Management strategies seek to minimize the opportunity for effective contact between bats and horses,and limit potential horse-to-horse and horse-to-human transmission. Incomplete knowledge of the ecology of the virus,of the proximate factors associated with spillover,and the inherent difficulties of effectively managing wild populations,preclude a management approach targeted at bats. 展开更多

The Chinese Grouse (Tetrastes sewerzowi) is a rare, endemic bird in China, inhabiting conifer-dominated mountain forests. Both the natural fragmentation and heavy cutting of mature forests have resulted in patchy grouse habitats. We used SPOT (XS-sensor) satellite imagery to discriminate between open land and conifer or broadleaf forests. The area analyzed is about 120000 ha in size and includes the Lianhuashan Nature Reserve and the Yeliguan Forestry Park. We identiifed 4111 ha of mature coniferous forests in 229 patches (maximum 332 ha, mean 18 ha) as the habitat used by Chinese Grouse throughout the year. We examined 31 forest islands of different sizes and degrees of isolation for the presence of Chinese Grouse. We used generalized linear models (GLM) with binomial error structure and logit link function to estimate the probability of Chinese Grouse occupancy in a forest fragment. Habitat patch size (hs) and distance to the next occupied fragment (doc) were used as predictor variables, important for occupancy. Small habitat islands were disproportionately less likely to be occupied than large, nearby habitats. There was a clear speciifc habitat size of about 40 ha, above which habitat fragments were occupied more often. Suitable habitat fragments isolated by more than 2 km appeared to be inaccessible to Chinese Grouse. The results have been used in reforestation projects to establish linking corridors in the study area. 展开更多

Traumatic intracranial pseudoaneurysms (TIPA) are rare and pseudoaneurysm of P3 segment of the posterior cerebral artery (PCA) is extremely rarely reported. A 27-year-old man suffered from blunt head injury and underwent diagnostic procedure with head CT scans, cerebral CT angiograms (CTA) and digital subtraction angiograms (DSA). An abnormal high-density lesion was detected at the left side of quadrigeminal cistern and a pseudoaneurysm showed at the P3 segment of PCA. The pseudoaneurysm was successfully treated with parent artery occlusion (PAO). Making an exact preoperative diagnosis of traumatic intracranial pseudoaneurysms is of great importance. Endovascular techniques allow a safe approach to complex intracranial lesion, so endovascular management of PCA pseudoaneurysms becomes safe and effective. However, the pseudoaneurysm may not be amenable to coil placement under some conditions, thus, occlusion of the parent vessel may be a preferable treatment. 展开更多

The paper examined the consumption pattern and attitude of households for local and imported rice in Ekiti State, Nigeria. The specific objectives of the paper are to: examine the household preference and consumption level of local and imported rice, examine price variation between local and imported rice and identify the major problems confronting marketers of local and imported rice. Data were collected from 100 randomly chosen households with the aid of structured questionnaire. Data collected were analyzed with the use of descriptive statistics such as frequency, percentages, chi-square, t-test and regression analysis. The paper revealed among others that majority of the respondents prefer to consume local rice to imported rice because of its more palatability, health benefits, readily availability and relatively cheap price. The average price per kilogramme of local rice is 200 Naira compared to that of imported rice which is 300 Naira. The difference in price is as a result of exchange rate and costs associated with smuggling of imported rice across the border of Nigeria from neighbouring countries. Nonetheless, the quality of local rice is still very low when compared to imported rice in terms of degree of impurities such as stone and shafts and the level of polishing. 展开更多

In order to determine the quantity of laboratories doing waste minimization practice related with the USEPA (United State Environmental Protection Agency) pollution hierarchy, an initial diagnostic about waste management at laboratories was conducted. The data gathered were used to start a training to laboratory personnel training about EPA-PH (Environmental Protection Agency-Pollution Hierarchy). After training new diagnostics were performed. The applications of waste minimization practices in the laboratories were analyzed before and after the training. The most poorly practices performed year by year during the study period were "substitute nonhazardous materials", "chemical treatment" and "distillation". "Redistribute surplus chemical" was performed in 22 labs, 30 labs and 48 labs during years 2010, 2011 and 2013 respectively as the most common practice. This study showed that training about pollution prevention hierarchy increased the number of laboratories doing waste minimization practices, prioritizing reduction and prevention from the source. 展开更多
