Warfarin therapy is known as a complex process because of the variation in the patients' response. Failure to deal with such variation may lead to death as a result of thrombosis or bleeding. The possible sources of variation such as concomitant illnesses and drug interactions have to be investigated by the clinician in order to deal with the variation. This paper describes a decision support system (DSS) using Bayesian networks for assisting clinicians to make better decisions in Warfarin therapy management. The DSS is developed in collaboration with a Swedish hospital group that manages Warfarin therapy for more than 3000 patients. The proposed model can assist the clinician in making dose-adjustment and follow-up interval decisions, investigating variation causes, and evaluating bleeding and thrombosis risks related to therapy. The model is built upon previous findings from medical literature, the knowledge of domain experts, and large dataset of patients.

EFFORTS TOWARDS SYNTHESIS OF HYDROGEN SULFIDE ACTIVATED BODIPY BASED PDT AGENT Canyurt, Merve; Günbaş, Emrullah Görkem; Department of Chemistry (2022-5-13) Photodynamic Therapy (PDT) is an effective and minimally invasive method that has recently gained widespread acceptance as a new medical treatment for a variety of conditions. PDT uses photosensitizers in combination with a specific light source and molecular oxygen to form cytotoxic species that can damage organelles and cell membranes directly. The photodynamic reactions start with light absorption by the PS in the target tissue, which sets off a chain of photochemical events. In comparison to existing se...
Computerized hybrid decision-making system for hormone replacement therapy in menopausal women Bacak, Hikmet Özge; Leblebicioğlu, Mehmet Kemal; TANAÇAN, ATAKAN; BEKSAÇ, MEHMET SİNAN (IOS Press, 2019-01-01) BACKGROUND: The diversity of the results of different hormone replacement therapy (HRT) protocols and the fuzziness of the conclusions have caused problems in routine clinical practice.
Vaka İncelemesi: Bir Obsesyon Nevrozu Vakasının Psikanalitik Kuram Üzerinden İncelenmesi Örneği POLAT, Makbule Su; Gençöz, Faruk (Orta Doğu Teknik Üniversitesi (Ankara, Turkey), 2020-2-28) Söz konusu çalışma obsesyon nevrozunun çeşitli semptomlarını sergilediği düşünülen bir kişinin psikoterapi seanslarının kuramsal incelemesidir. Obsesyon nevrozunun semptomatolojisinin günümüzde aldığı görünümlere getirilebilecek kuramsal açılımlar çalışmanın temel konusudur. Obsesyon nevrozunun semptomlarının görünümleri farklı çağlara göre değişebilse de nevrozun çekirdeğini oluşturan yapının baki kaldığı düşüncesi çalışmanın oluşturulmasındaki motivasyon niteliğindedir. Ayrıca, söz konusu vakayı Lacanyen ...
Polyinosinic: polycytidylic acid loading onto different generations of PAMAM dendrimer-coated magnetic nanoparticles Khodadust, Rouhollah; Mutlu, Pelin; Yalcin, Serap; Unsoy, Gozde; Gündüz, Ufuk (2013-08-01) Poly (I:C), which is a synthetic double-stranded RNA, have significant toxicity on tumor cells. The immobilization of Poly (I:C) onto nanoparticles is important for the fabrication of targeted delivery systems. In this study, different generations of newly synthesized PAMAM dendron-coated magnetic nanoparticles (DcMNP) which can be targeted to the tumor site under magnetic field were efficiently loaded for the first time with Poly (I:C). Different generations of DcMNPs (G(2), G(3), G(4), G(5), G(6), and G(7...
Feedback controlled electrical nerve stimulation: A computer simulation Doruk, R. Ozgur (Elsevier BV, 2010-07-01) The role of repetitive firing in neurophysiologic or neuropsychiatric disorders, such as Parkinson, epilepsy and bipolar type disorders, has always been a topic of medical research as therapies target either the cease of firing or a decrease in its frequency. In electrotherapy, one of the mechanisms to achieve the purpose in point is to apply a low density electric current to the nervous system. In this study, a computer simulation is provided of a treatment in which the stimulation current is computed by n...
