مقدمه و اهداف: در سالهای اخیر، توجه قابل ملاحظهای به مدلهای آماری برای طبقهبندی دادههای پزشکی با توجه به بیماریهای مختلف و پیامدهای آنها شده است. شبکههای عصبی مصنوعی به دلیل عدم نیاز به پیش فرض با موفقیت برای تشخیص الگو و پیشبینی در برخی از مطالعه های بالینی استفاده شدهاند. هدف از این مطالعه، مقایسه دو مدل آماری شبکه عصبی مصنوعی و رگرسیون لجستیک برای پیش بینی بقای بیماران مبتلا به سرط...
The InterMed Collaboratory is collaborative project involving six participating medical institutions (Stanford University, Columbia University, Brigham and Women’s Hospital, Massachusetts General Hospital, McGill University, and the University of Utah). There are two broad mandates for the effort. The first is to further the development, sharing, and demonstration of numerous software and syste...
The results of toxicology screening of samples from 725 patients admitted to the Critical Care Medical Center (CCMC) of Nippon Medical School during a 10-month period from 1992-1993 (Group A) and a 4-month period from 1995-1996 (Group B) were discussed. We investigated the drug use of emergency patients using immunoassay. EMIT and Triage. The results were confirmed by Gas Chromatography/Mass Sp...
Of the seven signal transducers and activators of transcription that have been identified, STATs 1, 3, and 5a/5b can be activated not only by a multitude of cytokines but also by some growth factors. The data presented here demonstrate that, in contrast to activation by the cytokine, growth hormone (GH), the activation of STAT5b by the growth factor, epidermal growth factor (EGF), requires over...
The nonphotochemical reactions of phytochrome in the coleoptiles of dark-grown corn seedlings were studied at 3 temperatures: 14 degrees , 24 degrees , and 34 degrees . The data obtained show that the destruction of P(fr) is the only measurable reaction occurring; reversion of P(fr) to P(r) was not found. The Q(10)'s (2.7 and 3.5) and zero order kinetics found for the destruction reaction are c...
Plants, as well as fungi, use ambient sunlight as information to regulate photomorphogenetic processes. The photobiological control of this information showed that the development of photobiological greenhouse plastic covers simulates a photonic information that leads to a physiological enhancement of plant productivity and fungal disease control, thus minimizing the need for the use of agroche...

Introduction: Recipients of corneal transplants are at risk of healthcare-associated infections, which, apart from other causes of surgical site infections, may also occur as a result of the transfer of infected corneal tissue. In this study we assessed the risk of bacterial and fungal infections based on the results of routine microbiological testing of cornea preservation fluid samples. Mater...
Context. Due to its relatively small distance (725 pc), the Cepheus A East star-forming region is an ideal laboratory to study massive star formation processes. Aims. Based on its morphology, it has been suggested that the flattened molecular gas distribution around the YSO HW2 may be a 350-AU-radius massive protostellar disk. Goal of our work is to ascertain the nature of this structure. Metho...
