Fava Bean Ingestion: the Most Important Risk Factor of Hemolysis in G6PD Deficiency in Iran

Background: Glucose-6-phosphate dehydrogenase (G6PD) deficiency is one of the most known enzyme defects in Iran with various genetic mutations. We aimed to study the predisposing factors of hemolysis in children with G6PD deficiency. Methods: This study was done during 2007-2012 in two referral centers of Mofid Children’s Hospital and Baqiyatallah Hospital, Tehran, Iran. The hospital rec...

Sociolinguistic Folklore in the Study of African American English

Although sociolinguists have performed a valuable service in challenging folk theories about African American English (AAE), they also have unwittingly participated in the construction of sociolinguistic folklore about variation and change in AAE. Several examples of sociolinguistic myths are presented, including the supraregional myth, the change myth, and the social stratification myth. Data ...

Cytosolic Concentration of Ca2+ Regulates the Plasma Membrane H+-ATPase in Guard Cells of Fava Bean.

Opening of the stomata is driven by the light-activated plasma membrane proton pumping ATPase, although the activation and inactivation mechanism of the enzyme is not known. In this study, we show that the H+-ATPase in guard cells is reversibly inhibited by Ca2+ at physiological concentrations. Isolated microsomal membranes of guard cell protoplasts from fava bean exhibited vanadate-sensitive, ...

Evidence for G-Protein Regulation of lnward K+ Channel Current in Guard Cells of Fava Bean

Recent reports have shown that GTP-binding proteins (G-proteins) are present in plants but have given limited indication as to their site of action. G-proteins in animal cells transduce extracellular signals into intracellular or membrane-mediated events, including the regulation of ion channels. Using whole-cell patch clamp, we provide evidence that a G-protein in guard cells of fava bean regu...
