The role of surveillance endoscopic followup in colectomized patients with long standing total colitis is controversial. Here, we aimed to clarify its usefulness for the early detection of dysplasia and cancer in this group of patients. Ninety-seven colectomised UC patients followedup by surveillance endoscopy were retrospectively investigated by reviewing the pathological reports. Patients had...
One form of Impulse Radiating Antenna (IRA) combines the technologies of the Balanced Transmission-line Wave (BTW) sensor with TEM-fed paraboloidal reflector antennas. The behavior of the IRA was calculated using a combination of the Method of Moments, using the NEC Code, and Geometrical Optics. The results of NEC compare favorably to both high and low frequency asymptotes. The frequency domain...
introduction: recurrent abortion (ra) may be a consequence of aberrant expression of immunological factors during pregnancy. although the relative importance of immunological factors in human reproduction remains controversial, substantial evidence suggests that autoantibodies contribute to reproductive failure. production of such antibodies is under the control of cytokines; and leptin, beside...
Local antisera (LA) were compared with a common interim reference antiserum (IRA) to examine the antiserum component of the among-laboratory variation in an international collaborative study with 28 laboratories evaluating a candidate international Reference Material (apo-RM) for apolipoproteins A-I (apo A-I) and B (apo B). Measurement of the relative concentration of lyophilized preparations d...
Abstract— Equivalent charge method is used to design ultra wide band asymptotic conical dipole (ACD) antenna. Combination of linear charge density and point charges is used to generate different profiles for ACD antennas. Two different profiles of ACD antenna are used as a feed for reflector based impulse-radiating antennas (IRAs). This paper focuses on the selection of ideal ACD profile as wel...
