In this research, some of the inorganic complexes of uranyl with N- donor ligandswere synthesized. Complexes were characteriezed by FT-IR and UV spectra, ¹HNMR,¹³CNMR and some physical properties. The uranyl unit (UO2) is composed of a center ofuranium atom with the charge (+6) and two oxygen atom by forming two U=O double bonds.The structure is linear (O=U=O, 180) and usually stable. So other ...

Luotonins are alkaloids from the aerial parts of Peganum nigellastrum Bunge. that display three major skeleton types. Luotonins A, B, and E are pyrroloquinazolino-quinoline alkaloids, luotonins C and D are canthin-6-one alkaloids, and luotonin F is a 4(3H)-quinazolinone alkaloid. All six luotonins have shown promising cytotoxicities towards selected human cancer cell lines, especially against l...

Aim and objectives: Lead is one of the most important environmental pollutants that plays a significant role in increasing the stability of some other pollutants through changing the microbial profile of soil.  Bacillus subtilis WPI is one of the most abundant bacteria existing in the wastewater. Due to the presence of laccase enzyme in this bacterium, it can facilitate the decomposition proces...

In recent years, more and more biochemists and pharmacologists have paid their attention to research on other transition metal complexes such as ruthenium (II), copper (II), zinc (II), nickel (II), cobalt (II) complexes compared with traditional platinum compounds in treatment of human cancer due to their potential applications as chemical and stereoselective probes of nucleic acid structures a...

Neuronal circuits modify their response to synaptic inputs in an experience-dependent fashion. Increases in synaptic weights are accompanied by structural modifications, and activity dependent, long lasting growth of dendritic spines requires new protein synthesis. When multiple spines are potentiated within a dendritic domain, they show dynamic structural plasticity changes, indicating that sp...
