In vitro inhibition of the paraoxonase from human serum with sulfonamide
S Sinan
African Journal of Biotechnology , 2008,
Abstract: This study was conducted to determine the in vitro effects of sulfonamide on human serum paraoxonase (PON1) activity. The enzyme was purified by two-step using ammonium sulfate precipitation and sepharose-4B-L-tyrosine-1-napthylamine hydrophobic interaction chromatography. Sulfonamide was an effective inhibitor on purified human serum PON1 activity for phenylacetate and paraoxon as substrates with IC50 values of 0.22 and 0.81 mM, respectively. The kinetics of interaction of sulfonamide with the purified enzyme indicated a different inhibition pattern for two substrates. Sulfonamide showed a non-competitive inhibition with Ki of 0.0037 ± 0.0009 mM for phenylacetate and competitive inhibition with Ki of 0.0057 ± 0.0002 mM for paraoxon.

Assessment of Corporate Governance in Jordan: An Empirical Study
Mohammed Shanikat,Sinan S. Abbadi
Australasian Accounting Business and Finance Journal , 2011,
Abstract: This paper assesses the reality of corporate governance in Jordan. It identifies the framework of corporate governance, which has here been set into two dimensions – institutionalisations and regulations – and describes the five major principles of corporate governance. The study was carried out by interviews with key employees and the review of related laws and selected annual reports. The study found (1) basic shareholder rights were honoured in decision-making, except for large decisions such as major asset sales; (2) shareholders were not treated equitably in practice, although controllers sometimes took action and prohibited insider trading; (3) the role and rights of stakeholders in corporate governance were respected, and stakeholders had a number of legal protections, which were largely covered in Jordan's Company Law; (4) disclosure and transparency were observed to a large extent, although limited to quantity rather than quality, because Jordan has fully adopted IFRS and ISA and (5) boards largely fulfilled their responsibilities, as these are extensively defined by law and regulation.
Fertility preservation in females with malignant disease-1: causes, clinical needs and indications
Murat S?nmezer,Sinan ?zkavuk?u
Turkish Journal of Hematology , 2009,
Abstract: Cancer incidence is progressively increasing in parallel with an increase in the rate of cancer survivors with the help of advanced treatment modalities. By the year 2010, it is estimated that one in every 250 persons will have survived a childhood malignancy. The increased rates of survival bring about complications related to reproductive health. Cytotoxic treatments due to chemo- and radiotherapy or bone marrow transplantation suppress or irreversibly harm not only female ovarian reserve but also male testicular sperm production. In this review, cryopreservation of gametes and gonads with fertility preservation options and indications prior to cancer treatments are discussed.
Time Dependent Wave Packet Study of the H-+ H2 Nonreactive Scattering  [PDF]
Sinan Akpinar, Seda Surucu
Journal of Quantum Information Science (JQIS) , 2011, DOI: 10.4236/jqis.2011.12013
Abstract: Time dependent wave packet calculations have been performed for the H-+ H2nonreactive scattering, summed of elastic and inelastic probabilities, on the recent reported potential energy surface of the systems. The total probabilities for total angular momentum J up to 35 have been calculated to get the converged integral cross sections over collision energy range of 0.20 - 1.42 eV. Integral cross-sections and rate constants have been calculated from the wave packet transition probabilities for the initial states (υ = 0, j = 0) by means of J-shifting method and uniform J-shifting method for J > 0.
A Novel Hybrid Approach to Estimate Customer Interruption Costs for Industry Sectors  [PDF]
Sinan Kufeoglu, Matti Lehtonen
Engineering (ENG) , 2013, DOI: 10.4236/eng.2013.510A006
Abstract:

The power system infrastructure, operations and market have gone through radical changes for the last couple of decades. The society has become more dependent to the continuous electric power supply and hence the concept of electric power reliability has become more significant. At this point, understanding the economic outcomes of power outages is vital and imperative for both utilities and the customers. There are certain methodologies to understand the costs of power interruptions. This paper suggests a novel hybrid method that comprises of customer surveys and direct analytical methods to reach customer specific, objective and reliable results for the industry sector customers. The paper also brings a statistical approach to censor the zero and extreme responses given via the surveys.

An artificial neural network application on nuclear charge radii
S. Akkoyun,T. Bayram,S. O. Kara,A. Sinan
Physics , 2012, DOI: 10.1088/0954-3899/40/5/055106
Abstract: The artificial neural networks (ANNs) have emerged with successful applications in nuclear physics as well as in many fields of science in recent years. In this paper, by using (ANNs), we have constructed a formula for the nuclear charge radii. Statistical modeling of nuclear charge radii by using ANNs has been seen as to be successful. Also, the charge radii, binding energies and two-neutron separation energies of Sn isotopes have been calculated by implementing of the new formula in Hartree-Fock-Bogoliubov (HFB) calculations. The results of the study shows that the new formula is useful for describing nuclear charge radii.
The Effects of Broiler Breeder Age and Extra Oxygen Addition into Incubator at High Altitude (1700 m) on Hatching Results and Subsequent Performance in Broilers

Journal of Animal and Veterinary Advances , 2012,
Abstract: Breeder age and oxygen concentrations from 15-21 days of incubation were tested as factors determining on hatching and subsequent performances of broiler at high altitude. Eggs produced by breeders of 31 or 55 weeks of age. All eggs from 2 breeder ages were distributed randomly into 2 hatching cabinets, which were operated at different oxygen concentrations. The 1st cabinet was oxygenated at 25%, whereas, no oxygen added to the 2nd cabinet and called control group. Fertile hatchability was affected by the Oxygen supplementation and flock age interaction. The highest fertile hatchability was obtained when the breeders were 55 weeks of age with adding oxygen but not in breeders at 31 weeks of age. The fertile hatchability was decreased at 55 weeks of age in control group. The late embryo mortality was significantly depressed in embryos from breeders at 55 weeks of age when oxygen added. Chick weights of hatch, 1st and 3rd weeks among groups were not affected by interaction between Oxygen supplementation and flock age. Feed conversion ratio and mortality were enhanced in chicks obtained from breeders 55 weeks of age when oxygen added. It is concluded that oxygen supplement to the incubators at high altitude improves the fertile hatchability, feed conversion ratio and decreases mortality of chicks obtained from breeder of 55 weeks of age.

Global Journal of Medicine and Public Health , 2012,
Abstract: :Purpose: We evaluated post-course trainees’ satisfaction regarding to learning objectives, hands-on experience and increase overall knowledge of surgical oncological anatomy at the end of each theoretical and handson module with one year survey after the course. Materials and Methods: A total of 25 residents with their last year of residency were participants of this course.The course was given by faculty members of the Urology and Anatomy departments from various universities in our country.The procedures were defined by recommendations of the Turkish Board of Urology Training Program. At the end of each module evaluation of the course by the attendees included anatomy knowledge and surgical skills and were graded 1 to 4.A year telephone survey follow-up was conducted regarding progression report on their practices after the HCU course was given. At one year, the trainees were called to evaluate the efficacy of course (yes/no).Results: All participants completed the survey and 1 year follow-up evaluation after a year post-course demonstrated that the course improved their knowledge of surgical oncological oncology. The first day of the course, the mean satisfaction score was 3.37 and hands-on lab score was 3.55. In the second day, the mean satisfaction score of 3.22 and hands-on lab score was 3.45. Surgical anatomy lectures of radical prostatectomy, radical nephrectomy, radical cystectomy, pelvic lymph node dissection and demonstrational surgeries in cadaver sessions had higher scores than remaining subjects. Conclusion: Uro-oncologic surgical models using human cadavers are a feasible and effective method to learn the anatomical landmarks and surgical technique by in-training urologists.

International Journal of Poultry Science , 2005,
Abstract: A trial was conducted to investigate to effects of feed type (pellet and mash) on ascites in broiler. A total of 208 male chicks were used in this study. Pellet and mash feed group were formed in the study, pellet feed group fed on pellet and mash feed group fed on mash feed. Half of the animals from each group were moved to compartment with 16°C after 21 day. Body weights, feed conversion, weight gain and feed consumption of the chicks were calculated and mortality from ascites was recorded daily. On 42 day, blood samples were collected to determine hematocrit values. End of the study it was determined that feed type has no effect on body weight, weight gain, feed consumption and feed conversion rate. However, mash feed reduced the incidence of ascites.
