Abstract:Introduction: Patients with acute-on-chronic liver failure(ACLF) have different characteristics from those presented by non-ACLF patients diseases. The degree of ACLF impacts the outcome or without transplantation, divergences in literature, especially regarding post-transplant prognosis. Objectives: To review aspects ACLF, including concepts syndrome adopted various institutions, trea...
In this paper we report quantitative structure-activity models linking in vivo Drug-Induced Liver Injury (DILI) of organic molecules with some parameters both measured experimentally in vitro and calculated theoretically from the molecular structure. At the first step, a small database containing information of DILI in humans was created and annotated by experimentally observed information conc...
Copy-move forgery is a particular type of distortion where a part or portions of one image is/are copied to other parts of the same image. This type of manipulation is done to hide a particular part of the image or to copy one or more objects into the same image. There are several methods for detecting copy-move forgery, including block-based and key point-based methods. In this paper, a method...
The 13C chemical shifts for a series of compounds which includes carboxylic acids, aldehydes, ethers, ketones and hydrocarbons were simulated by using the parametric techniques. The observed chemical shifts were related to numerically encoded structural parametes called descriptors. Two new electronic descriptors were added to the previous descriptors. Ploting of experimental ver...
in this paper, the quantitative structure activity-relationship (qsar) of the ccr2b receptor inhibitors was scrutinized. firstly, the molecular descriptors were calculated using the dragon package. then, the stepwise multiple linear regressions (sw-mlr) and the genetic algorithm multiple linear regressions (ga-mlr) variable selection methods were subsequently employed to select and implement th...
This study presents some mathematical methods for estimating the critical properties of 40 different types of alkanes and their derivatives including critical temperature, critical pressure and critical volume. This algorithm used QSPR modeling based on graph theory, several structural indices, and geometric descriptors of chemical compounds. Multiple linear regression was used to estimate the ...
Purpose: This research is devoted to study the consistency between keywords extracted from abstracts of theses by the experts in the related fields and descriptors provided by the indexers in database of “Iran’s theses abstracts”. Methodology: This research is an applied study based on content analysis. A checklist which consisted of 32 criteria was used. In addition, we consulted the experts ...
Introduction: According to mortality rates in Iran, cardiovascular diseases, neoplasms, perinatal mortality, and respiratory tract diseases were top rate mortality in 2003(1382). To reduce mortality rate, Iranian medical community need to know more about recent therapeutic regimens. Two main medical databases are Pubmed and Embase. Researching Pubmed and Embase indexing methods and comparing Me...
mammography has been recognized as the best method of screening for breast cancer, for a long time. although the sensitivity of mammography is acceptable, it has limited specificity and a radiologist should be aware of limitations and pitfalls. there are different positive findings in mammography which are descriptors of breast disease including benign lesions or breast cancer. in this talk i w...
