geometrical structure, nuclear magnetic resonance (n1,1it) chemical shielding tensors, and chemical shiftsof silicon and carbon nucler are investigated for twn infinite size zigzag and armchair single-walled siliconcarbide nanotabes (sicnts). geometrical structures of sients, sit bonds and bond angles of st and cvertices in both zigzag and armchair nanotubes, indicate that bond lengths are appr...

to calculation non-bonded interaction of the [cocl6]3- complex embedded in nano ring, we focus on the single wall boron-nitride b18n18 nano ring. thus, the geometry of b18n18 nano ring has been optimized by b3lyp method with epr-ii (electron paramagnetic resonance) basis set and geometry of the [cocl6]3- complex has been optimized at b3lyp method with aldrich’s vtz basis set and stuttgart rsc 1...

background: 66ga (t1/2=9.49 h, β+: 4.153 mev, γ: 511, 834, 1039, 2752 kev) has a wide range of applications in different fields of medical sciences. production of 66ga became one of our main interests, according to its increasing applications in nuclear medicine, particularly in pet imaging. materials and methods: 66 zn (p,n)66ga reaction was determined as the best choice for the production of ...

In order to investigate the chemical composition of the nuclear pore complexes isolated nuclei from mature Xenopus laevis oocytes were manually fractioned into nucleo· plasmic aggregates and the nuclear envelopes. The whole isolation procedure takes no more than 6090 sec, and the pore complexes of the isolated envelopes are well preserved as demonstrated by electron microscopy. Minor nucleoplas...

Density functional theory methods(DFT) and natural bond orbital (NBO) analysis were used to investigate the effects of isomerism and side chain mutation at a microscopic level on the stability, binding energy and NMR/NQR tensors of structural isomers, L- methionylasparagine (Met-Asn) and L- asparagylmethionine (Asn-Met) in the gas phase. The results represented that the isomerism and side chain...

Background and objective: Clear Cell Renal Cell Carcinoma (CCRCC) is the most common adult renal neoplasm. Staging and grading of RCC are important predictors of survival. Fuhrman nuclear grading is widely used for CCRCC, the subjective nature of which has prompted more objective methods to evaluate nuclear features. Furthermore, Ki-67, a reliable marker of cellular pr...

Forensic anthropologists routinely macerate human bone for the purposes of identity and trauma analysis, but the heat and chemical treatments used can destroy genetic evidence. As a follow-up to a previous study on nuclear DNA recovery that used pig ribs, this study utilizes human skeletal remains treated with various bone maceration techniques for nuclear DNA amplification using the standard C...
