Neutrophil/lymphocyte ratio and Red blood cell distribution width are independent risk factors for 30-day mortality in Gastrointestinal system bleeding patients
Background. In this study, we aimed to examine demographic and endoscopic features of patients with GI bleeding to determine the factors affecting 30-day mortality.
Method. Patient’s demographic features, laboratory outcomes, comorbidities, drug use, endoscopy outcomes, Glasgow-Blatchford scores, and mortality status were examined. The factors affecting 30-day mortality were investigated.
Results. The mean age of the patients was 58.2±17.4 years, and 72.1% were male patients. 30-day mortality rate was found to be 14.4%. The mean age of patients who died was high (p0.05). Urea, neutrophils, red blood cell distribution width / platelet ratio, neutrophil / lymphocyte ratio and RDW levels were high, and hemoglobin level was significantly low in patients with a mortal progression (p0.05). Glasgow-Blatchford score was significantly higher in patients who died (p<0.05).
Conclusion. Many factors affect 30-day mortality in GI bleeding. It should be remembered that follow-up of patients with an advanced age who have comorbidity and impaired hemodynamics should be kept for long, and that these patients are at a high risk for mortality.
According to our results, NLR and RDW are independent factors that determine the 30-day mortality in upper GI bleeding
Effect of Ferula elaeochytris root extract on smooth muscle contraction of vas deferens gland in rat
Purpose: To evaluate the effect of Ferula elaeochytris (FE) at the prostatic and epididymal ends of rat vas deferens.
Methods: The effects of cumulative concentrations of FE (10 ÎĽL; 31.25 mg/ÎĽL and 20 ÎĽL; 62.5 mg/ÎĽL) were investigated on prostatic and epididymal ends of rat vas deferens in the presence of prazosin (0.3 ÎĽM), suramin (100 ÎĽM), atropine (10 nM) and nitric oxide synthase inhibitor (L-NOARG; 100 ÎĽM). The muscle contractions were induced by electrical field stimulation (EFS; 4 Hz, 50 V, 0.15 ms). Calcium (3 and 6 mM) was added into the bath medium while electrical field stimulation (EFS) was in progress.
Results: Ferula elaeochytris significantly inhibited the muscle contractions induced by electrical field stimulation (EFS) in a concentration-dependent manner. In the presence of prazosin or suramin, the contractile responses to EFS were significantly inhibited by FE at the prostatic and epididymal ends of vas deferens (p < 0.05). However, this inhibition was not affected by atropine and L- NOARG, suggesting that there is no direct interaction of FE with cholinergic and nitrergic responses. However, in the presence of prazosin or suramin, Ca2+ addition to the organ bath significantly reversed the inhibitory effect of FE at the prostatic and epididymal ends of vas deferens (p < 0.05).
Conclusion: These results show an inhibitory effect for the extract of FE on neurogenic contractile activity of prostatic and epididymal ends of vas deferens. This effect of FE may be associated with Ca2+ channels.

We are pleased to present the May-2012 issue of the Journal of Social Studies Education Research (JSSER). We would like to start with giving information about the first International Symposium on Social Studies Education: New Trends and Issues in Citizenship and Democracy Education in a Changing World’. Association for Social Studies Educators has successfully completed the first symposium in corporation with Marmara University and Council of Europe in 20-22 April 2012 in İstanbul, Turkey. The first International Social Studies Symposium took place with 250 participants from 11 different countries: Turkey, Brazil, Canada, England, The USA, Germany, France, Italy, Malaysia, Azerbaijan, Greece and Kirgizstan. There were 151 full oral and 4 poster presentations presented by the participants. This event provided opportunities for participant to exchange ideas and learn about perceptions of citizenship and citizenship education in different countrie
FROM THE EDITOR
Hello,
Thanks for joining us again in this November
2014 issue (V/2) of Journal of Social Studies
Education Research (JSSER). Our journal has
completed its 5 years with this current issue. As
the family of Association of Social Studies
Educators (ASSE), we are extremely delighted
and proud to see the blossoms that we first
watered in 2009.
JSSER has turned to a qualified electronic journal
that has been acknowledged and indexed by
various indexes in recent years. One of those
indexes has been recognized by Turkish Higher
Education Council as a database that includes
periodicals regarded as publishing quality
academic papers that fulfills the requirements for
applying associate professorship. Since its
foundation, ASSE, the publisher of the JSSER
has been playing the role of an instrument to
manifest and improve the “New Social Studies
Movement” which emerged through the end of
1990s. The mission of JSSER in this context is to
meet the requirement for academic periodical,
publishing studies on social studies education.
Being published as an electronic journal, JSSER
gives us an opportunity to take advantages of the
so called Information Age. As a matter of fact,
today’s electronic journals have a potential to
reach more readers than most of the best-selling
published periodicals of late 20th Century.
Nevertheless, the same technologies present some
risks that we cannot keep under control. The
problems that the have been experiencing in the
preparation processes of the last two issues are in
this kind. In this issue, we have also experienced
some communication problems as result of the
moving of JSSER’s technical substructure to the
Turkish Journal Park. As a result, only three
papers, whose peer-reviewing processes had
completed could be published in this current
issue: Rishabh Kumar Mishra “Social
Constructivism and Teaching of Social Science”,
Hatice Türe and Arife Figen Ersoy “Sosyal
Bilgiler Öğretmenlerinin Hoşgörü Algısı” (Social
Studies Teachers’ Perceptions of Tolerance) and
Feryal Çubukçu “Values Education Through Literary Texts”. These valuable papers have
potential to contribute the literature on social
studies education.
One of the main aims of ASSE was to establish a
regular scientific event through which social
studies educators from Turkey and abroad get
together to share their academic works and ideas.
In conjunction with the Faculty of Education of
Bolu Abant Izzet Baysal University we are
organizing the Fourth International Symposium
on Social Studies Education (ISSE) in April
2015.
The main theme of ISSE the 4th is “Peace
Education”. The preference of this theme
emphasizes on our hopes and determination for
our envision for peace in the late Ottoman
geography, in which guns have still been on fire
and people have still been shedding tears. And
this could be regarded as something similar to the
action of Mustafa Kemal Pasha who thought of
about the reconstruction of the country after the
war and assembled an “Educational Congress” in
Ankara to discuss educational issues, during the
most difficult days of the War of Independence in
1921. Adopting this approach, we have been
considering putting effort to institutionalize the
values of democracy, human rights, justice,
freedom of thought and freedom of conscience.
As a final remark, I would like to thank everyone
who contributed to the production of this issue
and special thanks to Assoc. Prof. Dr. Erkan Dinç
who acted as issue editor.
Best regards and hope to meet you in ISSE the
4th
From the Editor
We, JSSER/SBEAD family, are thrilled to meet with you once again with this latestissue of JSSER. Every issue released boosts our confidence that our future-targets are even closer to reach; our hopes climb higher that in the years to come we shall eventually be able to build a world where peace, freedom and welfare are the only ruling power.While I am writing these lines, there is a civil war breaking out in our close neighbor Syria. Hundreds of thousands of Syrians are facing death every second. They are losing their beloved ones. They are forced to flee their homeland in mass numbers and stuck in refugee camps in southeastern cities of Turkey and Jordan desperately waiting for the days that peace shall prevail in their homeland again. An infinite number of children are dead out of hunger in so many different countries. And yet we should not fall into the dark wells of despair, though we should be fully aware of these brutal facts. That is because next to all these negations there are also so many joyful things taking place in this ever-dwarfing world. For instance, advancement in information and communication technologies made people global citizens. The children of today’s world, the generation next, are not only aware of the fact that children dying of thirst in the 21stcentury Africa but they feel responsible to help them in any way they can. Turkish children, for example, donated their pocket monies and initiated charity events to raise funds for the children in need in African. Indeed, Turkish children have acted as mediators in opening hundreds of wells for the recent years in Kenya, just one example, to meet hundreds of people in need ofdrinking water. Besides, children of modern ages shall no longer take that is taught to them by their future-builders as the only fact because their critical thinking skills and means to use a variety of information sources have escalated so much. The nextgeneration shall manage to build a world better than today if only we as educators and scientists strive harder to train them for this journey
Numerical and experimental investigation of quench process
Numerical and experimental studies have been carried out to investigate the evolution of residual stresses in quenched components induced by temperature gradient and phase transformations. In the numerical analysis, a finite element model is implemented for predicting the temperature field, phase changes with their associated internal stresses in axisymmetrical steel components. The model is verified by several comparisons with other known numerical results. Case studies are performed to investigate the effects of the quench bath temperature and the specimen geometry. Specimen geometry has been analyzed by introducing a hole in a cylinder and varying hole diameter and its eccentricity. Experiments include microstructural examination and X-ray diffraction measurements of surface residual stresses
