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

This was, Merleau-Ponty thought, due to an objective volatilizing of the subjective role of the lived body in perception. In order to overcome the difficulties in the tradition of learning and the philosophy of consciousness, Merleau-Ponty's next important step was to take maximal grip as a central case of learning. To him, learning as being-in-the-world, basically has to be sketched out in embodied and socially contextualized situations. Drawing upon this asymmetrical identity from Merleau-Ponty, our argument in this paper is that learning is best understood as a phenomenon that involves the learner's engagement with the world and her intention to make sense of its structures. A new perspective is thus employed to present learning as an embodied and socially embedded phenomenon, which is always projected by habitual experience and involves transcendence. These characteristics of learning are brought together in an integral and comprehensive way and have relevance to studies of learning in institutions and in daily experience.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. In the last section, some important suggestions and comments are made in the light of the data obtained.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

When you are in a hurry, do you walk on the escalator to save time? Most of the major cities in China follow the "stand-right, walk-left" mle for escalators, that is to say, riders should stand on the right side and walk on the left side. Gradually, this rule has been followed by many people and has become the norm. In April this year, however, the Shang hai Metro released the latest version of its escalator instructions, which don't mention the "stand-right, walk-left" rule but, instead, prohibit walking on the escalators.This change disrupted the long-standing consensus and aroused heated discussion.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

With this increased interest, researchers need to assure that the public receives quality, evidence-based solutions. Improvements following a stress reduction intervention are generally assessed by a self-survey pre-post rather than objective biomarkers of stress. There is a need in the literature for a research paradigm utilizing two different stressors to prevent any alteration in post-intervention results due to habituation of the stressor. The Trier Social Stress Test (TSST) and the Beilock Stress Test (BST) are two different stress protocols published in the literature. The present study has three objectives: 1) to compare the efficacy of two different previously documented psychological stressors, the TSST and the BST;2) to compare an invasive measure, serum cortisol, to a non-invasive measure, the galvanic skin response (GSR);and 3) to examine the effects of sex on the response. Fifty-seven college age males (n = 31) and females (n = 26) completed both protocols. Blood samples were collected every 10 min for 110 minutes. Baseline, stressor, and recovery 1, 2, and 3 were averaged for a 20 min period. A 2 (test: BST or TSST) by 2 (sex: male or female) by 5 (trials: baseline, stressor, and recovery 1, 2, and 3) Mixed Plot ANCOVA with repeated measures on test and trial was used to analyze the data. There was not a significant main effect for test or sex for cortisol or the GSR. There was a significant difference for trial for both biomarkers: cortisol F(4,208) = 39.41;and GSR F(4,216) = 15.18. There was also a significant interaction term for sex × trial × test, F(4,208) = 4.51 and for test × trial, F(4,208) = 14.31 for cortisol. The conclusion is that the TSST and the BST can be used as pretest posttest stressors in translational studies assessing the effectiveness of a stress reduction technique if slight modifications are made in the statistical design.展开更多

It was hypothesized that visual and noise stimuli caused by the presence of humans affect the distribution of avifauna associated with this nature trail.Methods: Nine circular plots of 25 m fixed-radius laid along the trail(0 m), and 18 plots laid perpendicular to the trail at 75 and 150 m intervals, were studied from March 2013 to January 2014. The degree of human recreational disturbances was assessed in terms of visitor group size(visual disturbance) and their noise level(sound disturbance). These disturbances were categorized along a four-point scale(no human disturbance, low, medium and high disturbance). The relationship between disturbance levels and the abundance of birds was statistically tested.Results: ANOVA results revealed that the abundance of birds differed significantly under various intensities of recreational disturbances at each distance level. A significant negative correlation between abundance of birds and intensity of disturbance at 0 m distance suggests an avoidance of edge habitats by birds in the presence of humans. Abundance of birds increased at the 75 and 150 m distance levels with increasing disturbances occurring at the trail. Significant negative correlations were further observed between disturbance level and the abundance of birds in ground/understory and sub-canopy vertical strata of the forest at 0 m distance.Conclusions: Under high levels of recreational disturbance occurring at this trail, the abundance of birds near the trail declined significantly, while bird abundance in the interior of the forest increased. The sensitivity of individual bird species to visitor disturbances varied with the vertical stratum of the forest they usually occupy. Birds occupying the ground, understory and sub-canopy are particularly sensitive to recreational disturbances while bird species occupying the canopy and above are less vulnerable to recreational disturbances.展开更多

The presence of "comet-like" radial transport of acetylcholine receptors by actin microfilaments without the participation of myosin motors in the depression of acetylcholine-induced inward chloric current (...The presence of "comet-like" radial transport of acetylcholine receptors by actin microfilaments without the participation of myosin motors in the depression of acetylcholine-induced inward chloric current (ACh-current) in command neurons of defensive behavior of the land snail, Helix lucorum, in a cellular analog of habituation was investigated. For that purpose the effects of CK548, CK-636 (inhibitors of actin-related protein complex Arp2/3, whose activation triggers rapid actin polymerization and the formation of the "comet-like" tail on the actinic filament) and wiskostatin (an N-WASP protein inhibitor, activating Arp2/3) on the depression of ACh-current were studied. The attenuation of ACh-current depression was observed upon the addition of CK548. At the same time, CK-636 and wiskostatin irreversibly strengthened the depression of this current and suppressed its spontaneous recovery. The results of CK-548 action and its mathematical modeling allow suggesting the presence of "comet-like" transport of acetylcholine receptors, initiated by Arp2/3 protein complex in receptor endo and exocytosis in command neurons of Helix lucorum in a cellular analog of habituation. Irreversible inhibition of vital metabolic processes of the neuron by wiskostatin and CK-636, which lead to the decrease in the level of ATP, could have caused irreversible effects of these blockers on current depression.展开更多

The aim of the present study was to evaluate the effects of Sertraline administration in coping with stress using the behavioural paradigms of the acoustic startle reflex (ASR) and its prepulse inhibition (PPI) in both sexes. Wistar rats were divided into two groups: intact animals and exposed to restraint stress (RS) 3 times per day during 7 days, which were then subdivided into three other groups: injected with Sertraline (5 mg/kg/day) or the drug vehicle saline for 8 consecutive days, and non-injected. ASR and PPI values were analyzed along 4 sessions to determine behavioral changes. Upon it, we also determine the effects of acute immobilization stress analyzing physiological stress indicators in blood. Our data show sex differences in response to stress paradigms. RS affected more intensely males than females, disturbing the males’ growth and the long-term startle habituation that were not affected in females. PPI increased in the vehicle-injected animals when compared to baseline in both sexes, and Sertraline reversed more efficiently it in females. Moreover, despite both sexes exposed to stressful paradigms exhibited a significant increase in serum glutamic-oxaloacetic transaminase and lactate dehydrogenase enzymes when compared with intact controls, as well as leucopenia, some differences according to sex were found in the haemostatic response to stress. Notably, the repeated injections procedure disturbed the early response to stress, which Sertraline only attenuated in both sexes. Our data suggest that 8-day Sertraline administration is effective in reversing stress-induced changes in some physio-logical parameters, but insufficient to return immunological values to normality.展开更多

文摘Stress research has gained popularity due to the increased acknowledgement of chronic stress on personal health. With this increased interest, researchers need to assure that the public receives quality, evidence-based solutions. Improvements following a stress reduction intervention are generally assessed by a self-survey pre-post rather than objective biomarkers of stress. There is a need in the literature for a research paradigm utilizing two different stressors to prevent any alteration in post-intervention results due to habituation of the stressor. The Trier Social Stress Test (TSST) and the Beilock Stress Test (BST) are two different stress protocols published in the literature. The present study has three objectives: 1) to compare the efficacy of two different previously documented psychological stressors, the TSST and the BST;2) to compare an invasive measure, serum cortisol, to a non-invasive measure, the galvanic skin response (GSR);and 3) to examine the effects of sex on the response. Fifty-seven college age males (n = 31) and females (n = 26) completed both protocols. Blood samples were collected every 10 min for 110 minutes. Baseline, stressor, and recovery 1, 2, and 3 were averaged for a 20 min period. A 2 (test: BST or TSST) by 2 (sex: male or female) by 5 (trials: baseline, stressor, and recovery 1, 2, and 3) Mixed Plot ANCOVA with repeated measures on test and trial was used to analyze the data. There was not a significant main effect for test or sex for cortisol or the GSR. There was a significant difference for trial for both biomarkers: cortisol F(4,208) = 39.41;and GSR F(4,216) = 15.18. There was also a significant interaction term for sex × trial × test, F(4,208) = 4.51 and for test × trial, F(4,208) = 14.31 for cortisol. The conclusion is that the TSST and the BST can be used as pretest posttest stressors in translational studies assessing the effectiveness of a stress reduction technique if slight modifications are made in the statistical design.
文摘Background: We investigated the impact of human recreational disturbances on the distribution of birds along a popular nature trail in Sinhararja World Heritage Forest, Sri Lanka. It was hypothesized that visual and noise stimuli caused by the presence of humans affect the distribution of avifauna associated with this nature trail.Methods: Nine circular plots of 25 m fixed-radius laid along the trail(0 m), and 18 plots laid perpendicular to the trail at 75 and 150 m intervals, were studied from March 2013 to January 2014. The degree of human recreational disturbances was assessed in terms of visitor group size(visual disturbance) and their noise level(sound disturbance). These disturbances were categorized along a four-point scale(no human disturbance, low, medium and high disturbance). The relationship between disturbance levels and the abundance of birds was statistically tested.Results: ANOVA results revealed that the abundance of birds differed significantly under various intensities of recreational disturbances at each distance level. A significant negative correlation between abundance of birds and intensity of disturbance at 0 m distance suggests an avoidance of edge habitats by birds in the presence of humans. Abundance of birds increased at the 75 and 150 m distance levels with increasing disturbances occurring at the trail. Significant negative correlations were further observed between disturbance level and the abundance of birds in ground/understory and sub-canopy vertical strata of the forest at 0 m distance.Conclusions: Under high levels of recreational disturbance occurring at this trail, the abundance of birds near the trail declined significantly, while bird abundance in the interior of the forest increased. The sensitivity of individual bird species to visitor disturbances varied with the vertical stratum of the forest they usually occupy. Birds occupying the ground, understory and sub-canopy are particularly sensitive to recreational disturbances while bird species occupying the canopy and above are less vulnerable to recreational disturbances.
文摘This paper intends to explore LI5 Xun's translation activities in the 1930s from the perspective of Bourdieu'ssociological theory. It elaborates on his text selection and his strategy choice in particular and finds out that hisunique translation practice is determined by his translation habitus and the social and cultural context in his time.And the construction of his translation habitus is closely related with his life experiences, political stand, and loftypatriotism.
文摘The presence of "comet-like" radial transport of acetylcholine receptors by actin microfilaments without the participation of myosin motors in the depression of acetylcholine-induced inward chloric current (ACh-current) in command neurons of defensive behavior of the land snail, Helix lucorum, in a cellular analog of habituation was investigated. For that purpose the effects of CK548, CK-636 (inhibitors of actin-related protein complex Arp2/3, whose activation triggers rapid actin polymerization and the formation of the "comet-like" tail on the actinic filament) and wiskostatin (an N-WASP protein inhibitor, activating Arp2/3) on the depression of ACh-current were studied. The attenuation of ACh-current depression was observed upon the addition of CK548. At the same time, CK-636 and wiskostatin irreversibly strengthened the depression of this current and suppressed its spontaneous recovery. The results of CK-548 action and its mathematical modeling allow suggesting the presence of "comet-like" transport of acetylcholine receptors, initiated by Arp2/3 protein complex in receptor endo and exocytosis in command neurons of Helix lucorum in a cellular analog of habituation. Irreversible inhibition of vital metabolic processes of the neuron by wiskostatin and CK-636, which lead to the decrease in the level of ATP, could have caused irreversible effects of these blockers on current depression.
文摘The paper introduces the three core concepts of Bourdieu’s sociological theory and their application in translation studies.The paper then examines and discusses the English translation of The Art of War from Bourdieu’s sociological perspective and the perspective of ephemerality.A comprehensive and objective description of the different translations of the same original text in different historical periods,the strategies of the translators,and the social,historical and cultural factors affecting the translation process can lead to a deeper understanding and proper orientation of translation.
文摘Translation activities,social environment and translators’individual particularities are combined in translation sociology which are provided broader theoretical perspective for translation studies.In this paper,Liang Shiqiu’s translation theory is analyzed from the perspective of translation sociology and there should be a new perspective which has expanded in the research of Liang Shiqiu’s translation theory.

文摘The serotonergic system in the brain plays a major role in mood and anxiety regulation when exposed to stress. The aim of the present study was to evaluate the effects of Sertraline administration in coping with stress using the behavioural paradigms of the acoustic startle reflex (ASR) and its prepulse inhibition (PPI) in both sexes. Wistar rats were divided into two groups: intact animals and exposed to restraint stress (RS) 3 times per day during 7 days, which were then subdivided into three other groups: injected with Sertraline (5 mg/kg/day) or the drug vehicle saline for 8 consecutive days, and non-injected. ASR and PPI values were analyzed along 4 sessions to determine behavioral changes. Upon it, we also determine the effects of acute immobilization stress analyzing physiological stress indicators in blood. Our data show sex differences in response to stress paradigms. RS affected more intensely males than females, disturbing the males’ growth and the long-term startle habituation that were not affected in females. PPI increased in the vehicle-injected animals when compared to baseline in both sexes, and Sertraline reversed more efficiently it in females. Moreover, despite both sexes exposed to stressful paradigms exhibited a significant increase in serum glutamic-oxaloacetic transaminase and lactate dehydrogenase enzymes when compared with intact controls, as well as leucopenia, some differences according to sex were found in the haemostatic response to stress. Notably, the repeated injections procedure disturbed the early response to stress, which Sertraline only attenuated in both sexes. Our data suggest that 8-day Sertraline administration is effective in reversing stress-induced changes in some physio-logical parameters, but insufficient to return immunological values to normality.
