BACKGROUND/AIMS At present, there is no simple test for predicting severity in acute pancreatitis. We investigated the use of an assay of soluble E-cadherin (sE-cadherin). METHODS Concentrations of sE-cadherin, from 19 patients with mild acute pancreatitis, 7 patients with severe acute pancreatitis, 11 patients with other acute gastrointestinal pathologies, and 12 healthy subjects were measur...
If G is not larger than H, and if the embedding is isomorphic, then there is no slowdown and the algorithm running on the system cannot tell the difference between G and H from the viewpoint of the above cost measures. When the guest graph is larger than the host graph, then the load of embedding must be at least VG/VH , where VG and VH are the numbers of nodes in the guest and host, respective...
This is a preliminary study of the effect of using microwave quads (MQs) instead of rf phase shifting to induce BNS damping in the main linac of the NLC collider. We consider MQs running at X-band, and find that the total length of MQs needed for the NLC is 6% of the total length of the accelerating structures. We show through simulations that, by using MQs instead of phase shifting for BNS dam...
Forty-four infants with acute lymphoblastic leukemia (ALL) characterized by MLL gene rearrangements were treated on a protocol of intensive chemotherapy followed by hematopoietic stem cell transplantation (HSCT) between November 1998 and June 2002. The remission induction rate was 91.0%, and the 3-year overall survival and event-free survival (EFS) rates, with 95% confidence intervals, were 58....
Human beings, even very young infants, and members of several other species, exhibit remarkable capacities for attending to and engaging with others. These basic capacities have been the subject of intense research in developmental psychology, cognitive psychology, comparative psychology, neuroscience, and philosophy of mind over the last several decades. Appropriately characterizing the exact ...
با پدید آمدن تکنیک‌های آماری قوی و شبکه‌های عصبی، مدل‌های پیش‌بینی کننده عملکرد محصولات زراعی به‌سرعت رو به توسعه است. بدین منظور آزمایشی در منطقه تربت‌حیدریه با هدف پیش‌بینی عملکرد و کارآیی مصرف آب زعفران با استفاده از مدل شبکه عصبی مصنوعی انجام گرفت. واسنجی و اعتباریابی مدل‌ها نیز با استفاده از آمار عملکرد محصول و پارامترهای اقلیمی سال 91-1390 صورت پذیرفت. ارزیابی مدل‌ها نیز با شاخص‌های آماری...
PURPOSE The aims of the present study were: (1) to compare the differences in the ball release speed and throwing accuracy between the ABOVE and SIDE throw; (2) to analyze kinematic differences of these two throwing techniques; and (3) to give practical applications to team handball coaches and players. METHODS Ball release speed, throwing accuracy, and kinematics were measured via the Vicon ...
Objectives: Serum hepatitis C virus (HCV) core antigen (HCVcAg) concentrations correlate with HCV RNA levels in HCV monoinfected patients. Data in HCV/HIV coinfected patients are still limited. We aim to compare the use of HCVcAg measurement with respect to HIV status, HCV genotypes, interferon-lambda-4 (IFNL4) polymorphism and clinical parameters. Methods: We analyzed an untreated cohort of 10...
Background: Jellyfish stings cause painful, papular-urticarial eruptions due to the immediate allergic, acute toxic and persistent inflammatory responses. In spite of many marine accidents and their economic impact, modes of first-aid treatment remain conventional and specific allergen and medical treatment are not yet available. The purpose of this study was to define the specific allergen of ...
Varicella-zoster virus (VZV) frequently causes severe infections in patients who have undergone bone marrow transplantation. The frequency of, characteristics of, and risk factors for this infection were studied in 164 patients undergoing autologous peripheral blood progenitor cell transplantation (PBPCT). Twenty-six patients (15.8%) developed VZV infection, and the actuarial risk was 10% at 1 ...
