this paper presents a macro model to predict unreinforced masonry structures in plane behavior. the model is based on the concept of multilaminate theory. in the past, the method has been used to model behavior of soil, disregarding the cohesion and the tensile strength. regarding its mathematical base, and the possibility of applying in other cases, this method is used to predict the ultimate ...
the main objective of this study was to prepare colon-specific pellets of budesonide, using pectin as film coating. pellet cores of budesonide were prepared by extrusion / spheronization technique. pectin, in different ratios was combined with eudragit rs30d, eudragit ne30d or surelease to produce film coating. the dissolution profiles of pectin coated pellets were investigated in ph of 1.2 (2 ...
the exact role of the epithelial lining of the trachea in modulating the bronchial tone is controversial. the present study was an attempt to verify the role of both prostaglandins and mast cells in the acute phase of acid inspiration in rat. four groups (n = 6) of n. mari rats were employed. the first group was used as placebo control, and normal saline was injected. to the second group hydroc...
background:methotrexate (mtx) is one of the most commonly used disease-modifying antirheumatic drugs in the treatment of rheumatoid arthritis (ra) which can be associated with toxic effects on different organs. this study was designed to investigate the hepatotoxic effects in ra patients treated with mtx. methods: in this cross-sectional observational study, ra patients who received standard do...
in this paper, we give a necessary and sufficient condition for the equality of two symmetrized decomposable polynomials. then, we study some algebraic and geometric properties of the induced operators over symmetry classes of polynomials in the case of linear characters.
background: trace elements play an important role in a number of biological processes. astaxanthin (asx), a carotoid pigment found in certain marine plant and animals, has shown anti cancer and anti free radical properties. this work intended to understand the effect of astaxanthin in breast cancer (invasive ductal carcinoma, idc) by using micro-pixe method. for this aim the concentration of tr...
application of polymers in novel and advanced scientific technologies is increasingly expanding. in this regard, optical polymers among different materials have found a special and unique position. a novel dye doped polymer thin film was prepared by taking advantage of dye molecules' interaction with the host environment. this sample, like self-assembled structures, makes use of this inter...
the mechanical properties and microstructural developments of 321 stainless steel during thermomechanicalprocess were investigated. the repetitive cold rolling and subsequent annealing wereconducted to achieve nanocrystalline structure in an aisi 321 stainless steel. heavily cold rolling at−20°c was conducted to form martensite in metastable austenitic steel. the process was followed byannealin...
داروهای ضدالتهاب غیراستروئیدی یکی از پر مصرف ترین گروه های دارویی در درمان درد و التهاب و تب مطرح هستند. اما عوارض جانبی آنها از جمله عوارض گوارشی و کلیوی استفاده از این داروها را محدود می کند. یکی از مهمترین عوامل در ایجاد این عوارض جانبی، مهار آنزیم های سیکلواکسیژناز و سنتز پروستاگلاندین های محافظ می باشد، علاوه بر این، اثرات مخرب برخی از داروهای nsaids بر دستگاه گوارش ناشی از طبیعت اسیدی آنه...
clinical application of embryonic stem (es) cells faces difficulties regarding tissue rejection as well as ethical limitations. one solution for these issues is to reprogram somatic cells by the injection of their nucleus into an enucleated oocyte or zygote. however, technical complications and ethical considerations have impeded the therapeutic implications of this technology. an approach whic...
