This project was aimed to obtain more information about the habitus and social representations of college students reading habits, using as theoretical elements the principles developed by Pierre Bourdieu and Serge Moscovici. The project was developed in a public university, located in Mexico＇s northeast region; 19 students were part of the sample group. Two research tools were used to obtain data： survey and focus group. The project analyzed academic and environmental aspects, beyond the ＂ought to be＂, that affected the development and provided characteristics on the daily sociocultural reality of the students, with a view of the real environment of the students without ＂make-up＂. The project deepened into the analysis of the reading practices and not only the usual numeric indicators, which traditionally condemn the reading practices in Mexico. The results of this study showed that students read a lot more than what they and their teachers think they do, this taking into consideration electronic documents, general interest publications, and commercial magazines, among others. The point of view of some teachers and researchers, when it comes to reading habits recognize non-academic, simple and interesting reading more important impact on their reading habits shows a tendency to be pedantic and canonic; it does not for young people, which in the long term, could have a展开更多

Indeed, Bourdieu defines habitus in three different ways： as a capacity, as a set of dispositions, and as a scheme for practice. That is why he cannot solve the problem of the duality of agent and habitus and produces a problem offundamentation, as we can see in his troubles to determine which is the substratum of social actions. Though Bourdieu claims he borrows the concept of habitus from Husserl and other phenomenologists, many divergences can be stated in the way they conceive it. Unlike Bourdieu, phenomenology can establish precise relations of fundamentation between agent, habitus, and the ego because it avoids the fallacy of the wrong level involved in the attribution of systemic properties to personal eogic structures. Accordingly, it provides a consistent and precise concept of the habitus,展开更多

Today, it is well known how the wide social effects of social networking sites are widespread and effective. As far as it can be followed from written and visual media, it causes significant damages for attitudes and behaviors for individuals. Looking at the results of the study, it seems impossible to limit the time and necessity of these networks for people, but it is understood that people force their limits and capacity. It was determined that the general acceptance and rejection areas are mixed and the dominant distinctive effects were weakened. Unable to prevent social dissolution and deterioration was realized by these social networks of networks. However, we cannot only talk about negative effects because their positive effects should be mentioned. Data were obtained in this direction. For example, some segments encourage the users of these sites to have more freedom, to develop democracy and human rights awareness. However, the real problem is when and where to stand. This study;Social networking networks use information, attitudes and behaviors;It was carried out for the purpose of evaluating the use of nicknames and networks for the use of networks. The data of the study were obtained by the application of a questionnaire and the data obtained were analyzed with appropriate statistical analysis methods. In the first part of the study, field study/operational concept scanning is performed and theoretical information is included. In the second part, the purpose of the study, the problem status, the importance of the study, limitations, assumptions, problem question, research method, research universe and sample are specified and informed. In the third section, the data obtained using appropriate statistical methods are analyzed.

G. Don. The investigation involved the cell growth, ajmalicine production and enzyme activity related to indole alkaloid biosynthesis in both cell lines. These results indicated that C_ 20hi cells grew faster than C_ 20D cells, and average ajmalicine content in C_ 20hi cells was 18.4 times more than that in C_ 20D when cultured in the production medium. In the growth medium, average ajmalicine content in C_ 20hi cells was 31.9 times more than that in C_ 20D cells, while the cell growth has no obvious difference. The comparison of enzyme activities in C_ 20hi and C_ 20D cells indicated that tryptophan decarboxylase (TDC), strictosidine synthase (SSS) and geraniol_10_dehydrogenase (G10H) activities have no close relation to ajmalicine accumulation, although the activities of these enzymes were higher when cells were cultured in the production medium than in the growth medium. The C_ 20hi cells are relatively stable in five years of culture.展开更多

We report a rare case of a 29-year-old male patient with impressive megacolon, in whom Hirschsprung's or Chagas disease was ruled out. In the present case, dilatation of the colon was most likely due to a behavioral disorder with habitual failure of defecation. Chronic stool retention led to a bizarre bulging of the large bowel with displacement of the other abdominal organs and severe occult blood loss. Because of two episodes of life-threatening gastrointestinal bleeding despite conventional treatment of constipation, a surgical approach for bowel restoration was necessary. Temporary loop ileostomy had to be performed for depressurization of the large bowel and the subsequent possibility for effective antegrade colonic lavage to remove impacted stools. Shortly after the operation, the patient was healthy and could easily manage the handling of the ileostomy. However, the course of the megacolon in this young adult cannot be predicted and the follow-up will have to reveal if regression of this extreme colonic distension with reestablishment of regular rectal perception will occur.展开更多

Study Design: In this prospective study, 120 pregnant patients not ahead of 6th week and aged between 21 - 36 and diagnosed with habitual abortion between April 2011 and April 2012 in our clinic were included. Habitual abortion diagnosis criteria was based on patient history of three or more miscarriages before the 20th week and a genetically documented homozygote or heterozygote mutation of the methylenetetrahydrofolate Reductase gene. Results: The rate and the number of live births in the study group was 60 (93.75%) and statistically higher than the control group 32 (57.14%). The difference was found to be statistically significant (p = 0.001). The rate and the number of abortions in the control group was 24 (42.85%) and statistically higher than the study group 4 (6.25%). The difference was found to be statistically significant (p = 0.001). Conclusion: In order to maintain a healthy pregnancy an effective uteroplacental circulation is a must and any defects in haemostasis mechanisms may have an adverse influence. A few non-randomized studies comparing pregnancy results of low dose salycilic acid and low molecular weight heparin usage in patients also show that prophylaxis might be beneficial.展开更多

To investigate the influence of body iron status, weanling rats were fed a diet with low iron content (4 - 7 ppm) to induce iron deficiency anemia and olfactory behavior was compared to control rats fed an isocaloric diet sufficient in iron (210 - 220 ppm). Iron-deficient rats had prolonged exploratory time for attractive odorants in behavioral olfactory habituation/dishabituation tests, olfactory preference tests and olfactory sensitivity tests compared with control rats. No significant differences were observed for aversive odorants between the two groups. These findings suggest that iron-dependent functions may be involved in controlling and processing of olfactory signal transduction via self and lateral inhibition such that odorant signal remains stronger for longer times prolonging exploratory activity on attractive odorants in the behavioral tests. These findings establish that iron deficiency can modify olfactory behavior.展开更多

It’s found that the positive rate of AsAb in infertile patients was significantly higher than that in fertile control,being 36.6% vs 3.3% (P【0.001). AsAb was even more offen detected in recurrent aborting patients. Male patients whose spouses aborted 2-6 fetuses had significantly less SPIM than control, sperm count and sperm motility were also significantly decreased. But the incidence of pyospermia was significantly greater than that in control. It is concluded that AsAb and SPIM have played an important role in the development of recurrent abortions.展开更多

文摘Circulating antisperm antibodies (AsAb) and immunosuppressive material in seminal plasma (SPIM)were determined by solid-phase enzyme staining assay and anticomplement test respectively in 686 patients with abortion (including 285 couples) . 241 fertile couple served as control. It’s found that the positive rate of AsAb in infertile patients was significantly higher than that in fertile control,being 36.6% vs 3.3% (P【0.001). AsAb was even more offen detected in recurrent aborting patients. Male patients whose spouses aborted 2-6 fetuses had significantly less SPIM than control, sperm count and sperm motility were also significantly decreased. But the incidence of pyospermia was significantly greater than that in control. It is concluded that AsAb and SPIM have played an important role in the development of recurrent abortions.
