Epoxides undergo regioselective ring opening with various nucleophiles using catalytic amount of nano magnesium oxide and water as solvent under mild reaction conditions. The remarkable features of this method are improved yields, high regioselectivity, and green chemistry agreement.

1,1’-(Ethane-1,2-diyl)dipyridinium bistribromide (EDPBT) was used as a chemoselective and effective organocatalyst for the silylation of hydroxyl groups as well as desilylation of trimethylsilyl ethers under mild conditions at room temperature with good to excellent yields.

In this study, novel CuO/g-C3N4 nanocomposite was simply synthesized by impregnation of g-C3N4 with CuO nanoparticles. Then, the heterogeneous catalyst was characterized by various techniques including Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), thermogravimetric analysis (TGA) and transmission electron microscopy (...

The main objective of this research was to evaluate fifteen durum wheat (Triticum durum) genotypes selected from joint project of Iran/ICARDA for drought tolerance using several indices. The trials were conducted under moderate levels of drought stress for three cropping seasons (2004-2006) in four locations in the highlands western of Iran. The combined ANOVA for grain yield over years and loc...

There is need to develop simple, efficient & economically viable chemical pathways to synthesise biologically active & commercially important heterocyclic Bis(indolyl) methanes1.The indole ring is an important constituent of many natural products, pharmaceuticals & other compounds of commercial importantance2. The literature survey shows that Bis(indolyl) methanes are know...

BACKGROUND Our aim was to determine whether lymphangiogenesis occurs in the early steps of cancerogenesis of the upper aerodigestive tract. METHODS We assessed the number of lymphatics per unit area (lymphatic vascular density [LVD]) and the percent area occupied by the lymphatic vessels (lymphatic vascular area [LVA]) by computer-assisted morphometric analysis in 56 samples immunohistochemic...
