nonea medik. is a genus of the boraginaceae tribe boragineae, with approximately 35 species worldwide. examination of their palynological characters supported the separation of taxa, which is usually based on morphological and micromorphological reproductive features. pollen grains of 10 taxa representing three groups of taxa in iran, the n. caspica group, the n. persica group and the n. lutea ...

Background: Defects in endoplasmic reticulum homeostasis are common occurrences in different diseases, such as diabetes, in which the function of endoplasmic reticulum is disrupted. It is now well established that ion channels of endoplasmic reticulum membrane have a critical role in endoplasmic reticulum luminal homeostasis. Our previous studies showed the presence of an ATP-sensitive cationic...
The process of cytoplasmic cleavage has been studied in thin sections of rat erythroblasts and the cells of mouse leukemia and Walker 256 carcinoma of the rat. The development of the cleavage furrow begins in relation to the mid-body, which, earlier, appears on the equatorial plane in association with the continuous fibers of the spindle. The earliest evidence of a cleavage furrow is the presen...
Hartree-Fock (HF) and Density Functional Theory (DFT) methods employed to study the effect of conformational change on the 13C chemical shifts of 6-mono axial and equatorial substituted and 6,7-di axial-axial, equatorial-equatorial and axial-equatorial substitutedderivatives of 5,6,7,8-tetrahydrodibenzo[a,c]cyclo-octene. The geometry of the conformers have been optimized...

Using three cluster model, the ternary fission of (_"98" ^"252" )Cf is studied. We applied collinear and equatorial configurations to study the ternary fission of (_"98" ^"252" )Cf when three fragments are Sn, Ni and Ca. The potential energy of collinear and equatorial configurations is calculated. We calculated the potential energy for odd and even values of A3. Also, we compared the potential...

introduction: intracellular ph (phi) regulates essentially all aspects of cellular activities. however, it is unknown how endoplasmic reticulum (er) potassium channels sense phi. in this study, we investigate the direct effects of phi on er potassium channels. methods: we used channel incorporation into the bilayer lipid membrane method. l-α-phosphatidylcholine, a membrane lipid, was extracted ...
Perforation of the wall of the reticulum by a sharp foreign body often produces peritonitis and can cause involvement of other organs.In cattle the disease is economically important because of severe loss of production and high mortality rate.The objective of this study was to determine the presence and kinds of foreign bodies in apperently healthy buffaloes which were slaughtered in Ahva...
