BACKGROUND Magnetic resonance colonography (MRC) has been recently developed to assess bowel inflammation in inflammatory bowel disease (IBD) patients. Evaluating animal models of inflammation with MRC may be important in new drug-screening processes. The aim of this study was to assess the feasibility of MRC in colitic rats and confront it with model characteristics. METHODS Colitis was indu...

BACKGROUND Although chronic obstructive pulmonary disease (COPD) is a major global health burden there is a lack of patient awareness of disease severity, particularly in relation to exacerbations. METHODS We conducted a global patient survey using an innovative, internet-based methodology to gain insight into patient perceptions of COPD and exacerbations in a real-world sample typical of tod...

در این پژوهش، بسته آشکارساز کیفی اورانیوم حاوی شناساگرهای آرسنازو و برموپاداپ ساخته شده و با استفاده از شناساگر دیتیزون جهت تشخیص و تعیین برخی مزاحمت‌های یونی به روش رنگ سنجی، آشکارساز یون فلزی نیز ساخته شد. نتایج نشان داد که حد تشخیص یون اورانیوم با استفاده از آشکارسازهای حاوی شناساگرهای آرسنازو و برموپاداپ به ترتیب ppm‌50 و ‌ppm20 است و در محیط‌های اسیدی (5pH=) آشکارسازهای ساخته شده عملکرد من...

In this correspondence we presents the performance analysis of multiple-input multiple-output (MIMO) technique incorporating maximal-ratio combining with transmit antenna selection (MRC/TAS) in frequency-flat Rayleigh fading channels. The expression of probability density function (pdf) for MRC/TAS (Nt , 1; Nr) scheme has been derived. The probability of outage is examined first. Further by the...

In the era of fourth industrial revolution, productive thinking skills are in high demand. Creative thinking, critical and independent learning all part skills. A person’s ability to solve a problem with various alternatives can be measured range ways, is linked these abilities. Wolfram Mathematica cutting-edge technology that used visualize wide mathematical problems. The purpose this study wa...

Modified Rayleigh conjecture (MRC) in scattering theory was proposed and justified by the author (J.Phys A, 35 (2002), L357-L361). MRC allows one to develop efficient numerical algorithms for solving boundary-value problems. It gives an error estimate for solutions. In this paper the MRC is formulated and proved for static problems.

OBJECTIVE Since IVF program was first established, various types of media and culture systems have been developed either in-house or commercially. The aim of this study was to compare the efficacy of in-house Maria Research Center (MRC) media to that of commercially available Sydney IVF media in human day 3 embryo transfer cycles. METHODS Three hundred sixty nine couples were included in this...

Magnetic resonance cholangiography (MRC) has become the standard of reference for imaging of the biliary ducts. The use of three-dimensional (3D) sequences has resulted in improved spatial resolution with virtually isotropic voxel and improved signal/noise ratio. In addition to MRC images, 3D fat suppressed T1-weighted MR images should be systematically obtained to search for intrahepatic calcu...

Machine Reading Comprehension (MRC) is a great NLP task that requires concentration on making the machine read, scan documents, and extract meaning from text, just like human reader.One of MRC system challenges not only having to understand context answer but also being aware trust-worthy given question possible or not.Thought pre-trained language models (PTMs) have shown their performance many...
