Isolated duodenal rupture due to blunt abdominal trauma
Celik Atilla,Altinli Ediz,Onur Ender,Sumer Aziz
Indian Journal of Critical Care Medicine , 2006,
Abstract: Duodenal rupture following blunt abdominal trauma is rare and it usually seen with other abdominal organ injuries. It represents approximately 2% to 20% of patients with blunt abdominal injury and often occurs after blows to the upper abdomen, or abdominal compression from high-riding seat belts. Two cases of blunt duodenal rupture successfully treated surgically, are presented with their preoperative diagnosis and final out comes.
A rare case of duodenal duplication treated surgically
Mehmet Ali Uzun, Neset Koksal, Munire Kayahan, Atilla Celik, Gamze K?l?coglu, Selvinaz Ozkara
World Journal of Gastroenterology , 2009,
Abstract: Duodenal duplication, a rare congenital malformation, can also be observed in adulthood. Although it can be cystic or tubular, communicating or non-communicating, cystic and non-communicating forms are the most common. Several complications, such as obstruction, bleeding, perforation and pancreatitis, may result. Optimal treatment is total excision, although endoscopic procedures have also been described in appropriate cases. If total excision is not possible, subtotal excision and internal derivation can be performed. The 38-year-old woman presented here had occasional attacks of abdominal pain and obstruction, and we considered the diagnosis of duodenal duplication by abdominal computerized tomography. As we confirmed the diagnosis with operative findings and histopathological signs, we treated her with subtotal excision and intraduodenal cystoduodenostomy.

Creative Education (CE) , 2013, DOI: 10.4236/ce.2013.41002
Abstract: In this study, it was aimed to analyze supervisor-student relationship in the doctoral education based on views of students. For this reason, research assistants having completed doctoral education and got PhD title were asked what the contributions of their supervisors were and what kind of problems they experienced in doctoral education. Considering academic advising process, it was intended to shed a light on both formal and information sides of supervisor-student relationship. As a design of the study, qualitative case study method was used. In the light of the aim of the study, “semi-structured data collection form”, one of the qualitative data collection tools, was used to collect the data. The data gained from 19 research assistants having completed their PhD degrees in the past 36 months were analyzed with content analysis. The past/ongoing contribution of supervisors to their students’ education were classified under the themes of contribution to their personal development, contribution to academic development, contribution to professional development, and contribution to intellectual development. The students, being in intimate relationship with their supervisors, emphasize positive contributions of supervisors. However, the students, not being in an intimate relationship, underline the negative characteristics of their supervisors. Few of the participants utter ongoing contribution of supervisors. This study analyzes dimensions for the contribution of supervisors to students in doctoral education, and the experiences of students in these dimensions. In this regard, academicians who are supervisors or will be supervisors are expected to benefit from the study.
Effects of different priming treatments and priming durations on germination percentage of parsley (Petroselinum crispum L.) seeds  [PDF]
Atilla Dursun, Melek Ekinci
Agricultural Sciences (AS) , 2010, DOI: 10.4236/as.2010.11003
Abstract: The effects of different priming treatments and priming durations on germination percentage at different temperatures in parsley seeds were studied. The seeds were treated for 2, 4, 6 and 8 days with the PEG 6000 (–0.5 MPa, –1.0 MPa and –1.5 MPa), KNO3 (0.30 mol/L and 0.35 mol/L), Mannitol (0.50 mol/L and 0.60 mol/L) and hydropriming (12h, 24h, 36h and 48h) and unprimed (control). Germination studies were made at 5, 10, 15, 20 and 25°C. Percentage of germination at different temperatures was significantly affected by priming treatments. Hydropriming (12h, 24h and 36 h) and mannitol 0.60 mol/L at 2 day generally had the highest germination percentages. In general, the highest germination percentage with priming was determined at 10°C. It may be said that seed priming treatments increased seed germination percentage at both low and high temperatures. The highest germination percentages were observed in both hydropriming and mannitol treatments as compared with PEG and KNO3 treatments. The PEG and KNO3 (2 and 4 days) treatments were better than unprimed treatment in all of the temperatures.
The Feature-Based a New Object Coding Approach for Prismatic Parts at the Part Modeling  [PDF]
Ismet Celik, Ali Unuvar
Modeling and Numerical Simulation of Material Science (MNSMS) , 2013, DOI: 10.4236/mnsms.2013.34018
Abstract:

Use of features in order to achieve the integration of design and manufacture has been considered to be a key factor recent years. Features such as manufacturing properties form the workpiece. Features are structured systematically through object oriented modeling. This article explains an object coding method developed for prismatic workpieces and the use of that method in process planning. Features have been determined and modeled as objects. Features have been coded according to their types and locations on the workpiece in this given method. Feature codings have been seen to be very advantageous in process planning.

Effect of Lunar Synchronization on the Reproduction Time of Discus Fish (Symphysodon sp.) Under Controlled Aquarium Conditions
Pinar Celik,Ihsan Celik
Journal of Animal and Veterinary Advances , 2012, DOI: 10.3923/javaa.2011.890.893
Abstract: The reproduction times of the discus fish were observed for 2 years under fully-controlled production conditions. The position of the moon was also recorded on the spawning day of the fish at a light photoperiod of 14 h and a dark photoperiod of 10 h with water quality parameters of 27-30°C, pH 4.5-6.5 and conductivity of 80-200 μS. Of 102 observed reproductions, 28 occurred at the first quarter of the moon, 28 at full moon, 40 at the last quarter and 6 at new moon. Accordingly, it has been concluded that the discus fish display a reproduction behavior according to the lunar cycle even indoors, although they do not receive direct moonlight.

Cold, calcium and hypertension; is there a relationship between them?
Murat Celik,Turgay Celik
Journal of Experimental and Integrative Medicine , 2011,
Abstract: In their study published in this issue of the Journal of Experimental and Integrative Medicine, Kozyreva et al touched upon a quite interesting topic; the relationship between thermoregulation and immune system under the exposure of cold, and the modulator effect of exogenous Ca(2+) in hypertensive and normotensive rats. In that study, they observed that in thermoneutral conditions, the difference between hypertensives and normo-tensives in immune response parameters was small, some calcium-dependent mechanisms of immune response development can possibly be blocked by cold, and deep cooling on the background of administered Ca(2+) caused significant stimulation instead of suppression of the immune response in rats with arterial hypertension compared to normotensives. These observations can be explained not only the functional vascular properties of blood vessels, but also other physiological systems and molecular mechanisms involving in the response to cold in hypertensives. The prevalence of hypertension is increased in people who... [J Exp Integr Med 2011; 1(4.000): 241-242]
Induction of Parturition in Cows with Misoprostol
Atilla Yildiz
Journal of Animal and Veterinary Advances , 2012,
Abstract: The purpose of this study, was to determine the efficacy of intravaginal misoprostol for induction of parturition in cows. Twenty-seven multiparous Holstein cows with singleton pregnancies were used in this experiment. As randomly, cows were assigned to 1 of 2 treatment groups (n = 9) and a control group (n = 9). On day 270 of gestation cows in the treatment groups were received 200 μg or 400 μg of misoprostol (cytotec ) intravaginally. Intravaginal misoprostol was given every 6 h until the onset of labour. A maximum of 6 doses was administered. The average gestation length in control cows was 281 days. All induced cows (except for one cow administered 400 μg misoprostol) calved between 24 and 72 h after administered misoprostol. The 400 μg dosage of misoprostol resulted in induction failures of 11.1%. The rate of placental retention, birth weights, calving difficulty and calf viability did not differ among groups. Vaginal administration of misoprostol is an effective method of inducing parturition in the cow. Misoprostol could be used to produce a predictable calving time.

Journal of Animal and Veterinary Advances , 2012, DOI: 10.3923/javaa.2010.1345.1350
Abstract: The objectives were to determine the effect of ovsynch plus postbreeding infusion treatment combined with fixed time AI on pregnancy rate in healthy Holstein cows. A total of 36 cows ageing between three and eight were used. Cows were were randomly assigned to one of three treatment groups. Cows (n = 12) in first group (control) received no treatment; they were managed as healthy cows and inseminated at the first estrus after the voluntary waiting period. Second group (n = 12) received ovsynch protocol. Ovsynch protocol included administration of GnRH (2.5 mL im, Receptalfi, 0.004 mg Buserelin mL-1, Intervet) on day1, administration of PGF2α analogse D-Cloprostenol (2 mL im, Dalmazin, 0.075 mg D-Cloprostenol mL-1, Veta ) on day 8 and second GnRH administration on day 10. Animals in this group were artificially inseminated 18 h following 2nd GnRH administration. Third group (n = 12) received ovsynch but with the addition of 500 mg of Gentamycin sulphate (10 mL added to 30 mL of saline iu, Gentavet, 50 mg Gentamycin sulphate mL, Veta ) in 30 mL of saline by intrauterine infusion 2 h after artificial insemination. Pregnancy diagnosis was performed via rectal palpation 45 days post insemination. Pregnancy rate in the cows that received Ovsynch + Postbreeding infusion was higher (p<0.05) than that of cows synchronized with ovsynch. Based on the odds ratio, pregnancy rate for cows treated with Ovsynch + Postbreeding infusion increased 2.8 folds (Odds Ratio (OR): 2.80 (0,532-14,7355) 95% Confidence Interval (CI)) when was compared with control group and 6 folds (OR: 6.00 (1.0177-35.3753) 95% CI) when was compared with ovsynch group. The results of these studies indicate that acceptable pregnancy rates can be achieved in the recipients that have received the ovsynch plus postbreeding infusion protocol without the necessity of estrus detection.
