Electromagnetic Affects and Hemoglobin Synthesis

Cell-free Hemoglobin Synthesis

A cell-free protein-synthesizing system derived from rabbit reticulocytes is described which is dependent on the addition of transfer RNA for the translation of endogenous hemoglobin messenger RNA. Product analysis indicates that the system is active in the initiation of new chains. When hemoglobin is synthesized in the presence of a limiting amount of tRNA, there is a 50% decrease in (Y chain ...

Studies on Hemoglobin Biosynthesis: Asynchronous Synthesis of Hemoglobin a and Hemoglobin A2 by Erythrocyte Precursors.

Hemoglobin Synthesis in Avian Erythrocytes.

Hemoglobin is present in the nucleus of cells of the mammalian erythropoietic series as well as the nucleated red cells of amphibians and birds. Electron micrographs of frog and chicken erythrocytes demonstrate a direct continuity of hemoglobin between the cytoplasm and the interior of the nucleus through “pores” in the nuclear membrane (1). However, the origin of this nuclear hemoglobin has be...

Change in Oxygen Absorption of Human Adult and Fetal Hemoglobin Due to 940 MHz Electromagnetic Field Radiation Exposure

The effects of electromagnetic fields (EMFs) radiation at the frequency of 940 MHz on the structure and function of human adult and fetal hemoglobin (HbA and HbF) were studied. After extraction and purification of HbA and HbF, the oxygen absorption values for exposed and unexposed HbA and HbF to EMF were compared. The slope of oxygen absorption curve for exposed HbA was increased while that for...

synthesis and characterization of some macrocyclic schiff bases

ماکروسیکلهای شیف باز از اهمیت زیادی در شیمی آلی و دارویی برخوردار می باشند. این ماکروسیکلها با دارابودن گروه های مناسب در مکانهای مناسب می توانند فلزاتی مثل مس، نیکل و ... را در حفره های خود به دام انداخته، کمپلکسهای پایدار تولید نمایند. در این پایان نامه ابتدا یک دی آلدئید آروماتیک از گلیسیرین تهیه می شود و در مرحله بعدی واکنش با دی آمینهای آروماتیک و یا آلیفاتیک در رقتهای بسیار زیاد منجر به ت...
