بررسی کارایی عملکرد جاذب اصلاح شده کمپوزیتی نانو ذرات آهن صفر-کیتوزان در حذف آرسنات از محلولهای آبی
Background and Objective: Arsenic is one of the most toxic pollutants in groundwater and surface water. Arsenic could have lots of adverse impacts on human health. Therefore, access to new technologies is required to achieve the arsenic standard. Materials and Methods: The present study was conducted at laboratory scale in non-continuous batches. The adsorbent of zero-valent iron nanoparticl...
A convenient and gentle procedure was used for in vitro radioisotopic labeling the proteins of Newcastle disease virus. This method, which utilizes [14C]formaldehyde and sodium borohydride, labels all the proteins of purified Newcastle disease virus. Virions labeled in this manner retained biological and biopysical integrity
In this study we evaluated two different 99mTc-labeling techniques to produce 99mTc-low density lipoprotein (99mTc-LDL) suitable for the scintigraphic delineation of experimental atherosclerotic lesions. The two methods are 1) a procedure that uses stannous chloride and sodium borohydride (borohydride method) and 2) a procedure that uses sodium dithionite as a reducing agent and that has been s...
The rearrangement reaction of thebaine (1) with methanesulfonic acid, in the presence of hydrogen sulfide, resulted in a sulfide-type bisaporphine 13, instead of the expected thiol 12. The acidic hydrolysis of the thiocyanato derivatives 3, 9, 20 and 21, obtained from thebaine (1), as well as the reduction of 9 and 21 with sodium borohydride yielded disulfide-type bisaporphines 16 and 23.
