Incorporation of Flipped Learning into EFL Classrooms Performance and Perception
Innovative mobile-based tools have made new opportunities for learners to spend more quality time inside the classrooms. Keeping this in mind, the present study sought to examine the effect of the flipped classroom on developing EFL learners’ speaking and listening skills. To do so, 60 EFL students from two universities in Iran were assigned into one of the classes of flipped and conventional g...
متن کاملFerritins: dynamic management of biological iron and oxygen chemistry.
Ferritins are spherical, cage-like proteins with nanocavities formed by multiple polypeptide subunits (four-helix bundles) that manage iron/oxygen chemistry. Catalytic coupling yields diferric oxo/hydroxo complexes at ferroxidase sites in maxi-ferritin subunits (24 subunits, 480 kDa; plants, animals, microorganisms). Oxidation occurs at the cavity surface of mini-ferritins/Dps proteins (12 subu...
متن کاملReabsorption of iron into acutely damaged rat liver: A role for ferritins
AIM To studied iron metabolism in liver, spleen, and serum after acute liver-damage, in relation to surrogate markers for liver-damage and repair. METHODS Rats received intraperitoneal injection of the hepatotoxin thioacetamide (TAA), and were sacrificed regularly between 1 and 96 h thereafter. Serum levels of transaminases and iron were measured using conventional laboratory assays. Liver ti...

15 صفحه اولEffects of Ehrlich Ascites Tumor on Iron Incorporation into Heme*
The Ehrlich ascites tumor takes up intravenous Fe 59 and utilizes much of this for cellular heme formation. In vivo experiments showed tha t the amount of iron utilized by liver and marrow for heme synthesis was directly related to the amount of iron taken up by these tissues. In vitro experiments revealed no difference in iron-protoporphyrin chelation by liver mitochondria from control and tum...
