A new isolation procedure has resulted in an improved yield of stable 68S chloroplast ribosomes from Euglena gracilis var. bacillaris. Chloroplasts are isolated by suspending the cells in buffer I (sorbitol, 250 mm; sucrose, 250 mm; Ficoll, 2.5% [w/v]; magnesium acetate, 1 mm; bovine serum albumin, 0.01% [w/v]; mercaptoethanol, 14 mm; N-2-hydroxyethyl-piperazine-N'-2-ethanesulfonic acid, pH 7.6...
Background 3D-cell cultures are closer to in vivo conditions than the monolayers. There different culture models, most relevant is Cerebral Organoids (CO) model (Lancaster et al. 2014), it can show complex processes and proved molecular structural changes when modeling Alzheimer´s disease (AD), other diseases. One of main limitations using this requirement for Induced Pluripotent Stem Cells (iP...
background: many efforts have been undertaken until now to find an alternative approach to packed red cell tranfusion in major β-thalassemia. augmentation of fetal hemoglobin by hydroxyurea has proved to be less effective in this condition as compared to sickle cell anemia, probably due to molecular heterogeneity of the former disease. hydroxyurea efficacy and its relation to xmn1 polymorphism ...
background: mutations in β -globin gene may result in β-thalassemia major, which is one of the most common genetic disorders in iran and some other countries. knowing the beta-globin mutation spectrum improves the efficiency of prenatal diagnosis in the affected fetuses (major β-thalassemia) of heterozygote couples. methods: couples with high hemoglobin a 2 and low mean corpuscular volume we...
Udenfriend ‘s nitrosonaphthol test for 5-hydroxyindoleacetic acid (5-HIAA) is subject to interference by urinary phenolic acids and drug metabolites. Studies in our laboratory have shown that the specificity and sensitivity of the nitrosonaphthol reaction with 5-hydroxyindoles can be greatly enhanced by the addition of 2-mercaptoethanol. This observation serves as the basis of a simple, improve...
A number of polyacrylamide gel systems and solubilization procedures were studied to define the number and nature of "major" polypeptide bands in the outer membrane of Pseudomonas aeruginosa. It was shown that five of the eight major outer membrane proteins were "heat modifiable" in that their mobility on sodium dodecyl sulfate-polyacrylamide gel electrophoresis was determined by the solubiliza...
