Megakaryocytes (MKs) are one of the few cell types that become polyploid; however, the mechanisms by which these cells are designated to become polyploid are not fully understood. In this investigation, we successfully established two relatively synchronous polyploid cell models by inducing Dami and CMK cells with SP600125. We found that SP600125 induced the polyploidization of Dami and CMK cel...
Murine monoclonal antibody (mAb) Lym-1 is an immunoglobulin G2a specific for certain human leukocyte antigen-DR variants expressed on the surface of malignant B cells. It has been proposed for serotherapy in patients with B lymphomas. We have previously shown that mAb Lym-1 synergizes with granulocyte macrophage-colony stimulating factor to promote Raji B-lymphoid cell lysis by human neutrophil...
Quasielastic neutron scattering was used to study the dynamics of three-dimensional confined water in a hydrophobic mesoporous material designated as CMK-1 in the temperature range from 250 to 170 K. We observe a crossover phenomenon at temperature T(L) . We find that T(L) of water confined in CMK-1 occurs in between previous observations of one-dimensional confined water in materials with diff...
در این مقاله، کاربید بور با استفاده از دو نوع کربن (مزوپور کربنی cmk-1 وکربن سیاه)، اکسید بور و فرآیند احیاء منیزیوترمال سنتز شد. نقش نوع کربن بر روی تشکیل کاربید بور مورد بررسی قرار گرفت. برای این کار، ابتدا مزوپور کربنی cmk-1 با استفاده از روش قالبگیری توسط پیش سازه سیلیکاتی mcm-48 سنتزگردید و در ادامه با بهرهگیری از فرآیند منیزیوترمال، نمونهها با نسبت وزنی12: 5/1: 11=c:mgb2o2 در محدوده دم...
The mesoporous carbon (CMK-3) functionalized with ethylenediamine (EDA) has been synthesized (CMK-3-EDA) and applied as a new mesoporous adsorbent for removal of Cu(II) and Pb(II) cations from aqueous solutions. Nitrogen adsorption–desorption measurements (BET) show that surface area, pore size and pore volume of CMK-3 were significantly changed after amine modification. The BET surface area an...
Non-precious molecular cobalt phthalocyanine (CoPc) complexes have been considered to be promising electrocatalysts due diversity of substituents and carbon supporting matrixes. Here, we report a highly dispersed fluorinated CoPc (CoPcF16) molecule electrocatalyst immobilized in ordered mesoporous CMK-3 (CMK-3-CoPcF16) via π-π interaction. The is characterized by X-ray photoelectron spectroscop...
خلاصه در این پایان نامه برخی از ترکیبات هتروسیکلی جالب مانند پیرازولها، ایمیدازولها و پریمیدینها در حلال تری فلوئورو اتانول و کاتالیزگرهای سولفوریک اسید تثبیت شده روی سیلیکاژل ?(h2so4/sio2) و کربن مزو حفره ی منظم سولفونه شده (cmk-5-so3h) که اسیدهای جامد، کارا و سازگار با محیط زیست می باشند با راندمان بالا سنتز شدند. مشتقات 4-بروموپیرازول در مجاورت h2so4/sio2 بعنوان کاتالیزگر بدون حلال سنتز ...
During the growth of five of ten primary tumors that were induced by 3-methylcholanthrene in BALB/cMk and BALB/cMk x C57BL/6 F mice, leukemoid reactions, char acterized by increase in number of granulocytes in periph eral blood, and splenomegaly were observed. However, no such reactions occurred in five C57BL/6 mice bearing primary tumors induced by 3-methylcholanthrene. The results of leukemoi...
