objective: thrombotic thrombocytopenic purpura (ttp) is the most malignant variant of microangiopathy that usually presents by typical symptoms including thrombocytopenia, hemolytic anemia, neurological abnormalities, fever and renal impairment. report of the case: we report a 12-year-old male presented by cytopenia, fever, purpura on his extremities, seizure and lethargy. peripheral blood smea...
یکی از مهم ترین مشکلات راه آهن های درون شهری و خطوط سریع السیر، کنترل ارتعاشات ناشی از عبور قطارهاست. این ارتعاشات ضمن آسیب رساندن به زیرساخت های خط ریلی، باعث عدم آسایش ساکنین اطراف خط نیز می شود. یکی از راهکارهای کاهش ارتعاش، استفاده از بتن آسفالتی ــ به ویژه بتن آسفالتی اصلاح شده با لاستیک ــ در زیرسازی خطوط ریلی است. در این نوشتار به طور ویژه اثرات استفاده از آسفالت گرم )h m a(پانویس{h o t ...
odontogenic tumors constitute a group of heterogeneous lesions of benign and malignant neoplasms with variable aggressiveness. ameloblastomas are a group of benign but locally invasive neoplasms that occur in the jaws and are derived from epithelial elements of the tooth-forming apparatus. we previously described orosomucoid-1 protein expression in odontogenic myxomas. however, whether orosomuc...
In this short article, we observe that the path of particle of mass $m$ moving along $mathbf{r}= mathbf{r}(t)$ under pseudo-force $mathbf{A}(t)$, $t$ denotes the time, is given by $mathbf{r}_d= int(frac{dmathbf{r}}{dt} mathbf{A}(t)) dt +mathbf{c}$. We also observe that the effective force $mathbf{F}_e$ on that particle due to pseudo-force $mathbf{A}(t)$, is given by $ mathbf{F}_e= mathbf{F} mat...
copper complexes of [cu(phen)(tda)].2h2o(1) and [(phen)2cu(µ-tda) cu(phen)](clo4)2.1.5h2o (2) (where phen is 1,10-phenanthroline and tda2- is thiodiacetate) have been synthesized. both complexes were characterized by elemental analysis, ir, uv–vis spectroscopy and cyclic voltammetry. their solid state structures were determined by the single crystal x-ray diffraction method. complex 1 is mononu...
the ability to maintain and study human tissues in in-vivo environment has proved to be a valuable tool in breast cancer research for several decades. the most widely tissues have been xenografts established human breast cancer cell lines into athymic nude mice. the aim of this study was to provide a new accurate and affordable method for the establishment of breast cancer xenograftin nude mice...
the dried plant was extracted with dichloromethane and after defatting with hexane, transferred repeatedly on silica columns using dichloromethane-hexane and ethyl acetate-hexane as mobile phases. finally the fractions were purified by high performance liquid chromatography using a pack-sil column and hexane: ethyl acetate as mobile phase. the structures of the isolated compounds included: cycl...
it has been reported that different species of euphorbia (euphorbiaceae) have antitumor activity. some reports also show that these plants have potential cytotoxic effect against different cell lines. in a program to screen the cytotoxicity of iranian native plants, euphorbia macroclada boiss. was collected, identified, and the cytotoxic activity of dichloromethane, ethylacetate, methanol extra...
in this paper, we shall define and study the concept of -statistical convergence and -statistical cauchy inrandom 2-normed space. we also introduce the concept of -statistical completeness which would provide amore general frame work to study the completeness in random 2-normed space. furthermore, we also prove some new results.
protonation of the reactive intermediate produced in the reaction between trimethyl phosphite and dimethyl acetylenedicarboxylate or diethyl acetylenedicarboxylate by resorcinol, 5-methylresorcinol, 2,5-dihydroxyacetophenone, 4-chloro-2-methylphenol, 4-chloro-3,5-dimethy-lphenol, 4-hydroxypyridine, 2-hydroxypyridine, 3-hydroxypyridine, or 8-hydroxyquinoline leads to vinylphosphonium salts, whi...
