زمینه و هدف: در بین باسیلوس ها، باسیلوس سرئوس، باسیلوس تورنجینزیس و باسیلوس آنتراسیس دارای اهمیت زیادی می باشند که از میان آن ها باسیلوس آنتراسیس عامل بیماری سیاه زخم می باشد. تولید توکسین در باسیلوس آنتراسیس توسط ژن pxo1 و پلاسمید مربوط به آن صورت می گیرد. اخیرا در تحقیقات نشان داده شده است که این ژن به سایر باسیلوس های یاد شده در فوق نیز انتقال یافته است. هدف این مطالعه جستجو و تعیین فراوانی ...
بررسی پروتئین های ذخیره ای بذر در 16 جمعیت از 6 گونه stipa l. ایران با استفاده از روش sds-page انجام گرفت. بطور کلی تعداد 29 باند پروتئینی مشاهده شد که تعدادی از آنها در تمامی گونه ها مشترک بودند. برخی از باند ها برای گونه ها اختصاصی بود و تعدادی نیز در میان جمعیت های یک گونه گوناگونی داشتند. تجزیه خوشه ای اطلاعات پروتئنی، جمعیت های هر یک از گونه ها را در خوشه ای مجزا قرار داد که نشان دهنده مت...
Several complementary experimental and theoretical methodologies were used to explore water uptake on sodium chloride (NaCl) particles containing varying amounts of sodium dodecyl sulfate (SDS) to elucidate the interaction of water with well-defined, environmentally relevant surfaces. Experiments probed the hygroscopic growth of mixed SDS/NaCl nanoparticles that were generated by electrosprayin...
The GH dose-response effect of long-term continuous GH treatment on adult height (AH) was evaluated in 54 short children born small for gestational age (SGA) who were participating in a randomized, double-blind, dose-response trial. Patients were randomly and blindly assigned to treatment with either 3 IU (group A) or 6 IU (group B) GH/m(2).d ( approximately 0.033 or 0.067 mg/kg.d, respectively...
template synthesis is a powerful method for the preparation of nanoscale materials with specific size and shape. cadmium oxide (cdo) nanoparticles were synthesized by using sodium dodecyl sulfate (sds), cd(oac)2.2h2o and sodium hydroxide as starting materials. the sample was characterized by x-ray diffraction (xrd), scanning electron microscopy (sem). the xrd pattern proves that the final produ...
We report on the adsorption of sodium dodecyl sulfate (SDS) onto functionalized graphene sheets (FGSs) in an aqueous system, measured at broad SDS and FGS concentration ranges by conductometric surfactant titration. At dilute SDS concentrations (<12 μM in bulk solution), there is evidence of a counterion exchange between hydronium ions (from the dissociation of acidic chemical functionalities o...
Interactions of a model surfactant, sodium dodecyl sulfate (SDS), with a water-insoluble model protein, zein, were investigated to gain an understanding of the effects, such as skin irritation and protein denaturation, of surfactants that are common in personal-care products. To elucidate the mechanisms of such effects, the zeinprotein interactionwithSDSinaqueoussolutionswas investigatedusingam...
In this work attempts were made to evaluate K+-SDS and hydrocolloid polymer-SDS interactions in flocculation of megestrol acetate dispersions to enhance their stability as a part of suspension formulation. Different dispersions of micronized megestrol acetate and SDS were prepared. KCl and KH2PO4 and their corresponding sodium salts were added to the dispersions and the preparations were evalua...
BACKGROUND Our study aimed to evaluate final height in a cohort of Dutch childhood cancer survivors (CCS) and assess possible determinants of final height, including height at diagnosis. PATIENTS AND METHODS We calculated standard deviation scores (SDS) for height at initial cancer diagnosis and height in adulthood in a cohort of 573 CCS. Multivariable regression analyses were carried out to ...
