The binding interaction of novel podophyllotoxin derivative, (3R,4R)-4-((benzo[d][1,3]dioxol-5-yl)methyl)-dihydro-3-(hydroxy(3,4-dimethoxyphenyl) methyl) furan-2(3H)-one (PPT), with calf thymus DNA (ctDNA) has been examined using UV-Visible absorption spectrophotometry, fluorescence spectroscopy, viscosity measurement and molecular docking studies. UV-Vis absorption results showed hyperchromic ...
a one dimensional dynamic model for a riser reactor in a fluidized bed catalytic cracking unit (fccu) for gasoil feed has been developed in two distinct conditions, one for industrial fccu and another for fccu using various frequencies of microwave energy spaced at the height of the riser reactor (fccu-mw). in addition, in order to increase the accuracy of component and bulk diffusion, instanta...
Apotransferrin (apo Tf) in 0.1 M N-(2hydroxyethyl)piperazine-N2-ethanesulfanic acid at 25 ˚C and pH 7.4 has been titrated with acidic solution of Tb3+. The binding of Tb3+ at the two specific metal-binding sites of transferrin was followed from the changes in the difference UV spectra at 245 nm. The molar absorptivity per binding site for Tb3+...
in this research dft/b3lyp method has been employed to investigate the geometrical structures,relative stabilities, and electronic properties of cun (n=3–10) clusters for clarifying the effect of sizeon the properties. through a careful analysis of the successive binding energies, second-orderdifference of energy and the highest occupied-lowest unoccupied molecular orbital energy gaps as afunct...
this research is about the political economy of china in central asia. in this research the political & economic interactions affected on chinas political economy in central asia are examined. chinas goal of presence in central asia including political-security, economic and energy goals is described in one part. in another part, the trade relations between china and central asian countries ar...
دراین تحقیق، مشتقات جدیدی از فنازین و 1،10-فنانترولین از طریق واکنش چهارتایی¬شدن دوگانه تهیه شد. ساختار این ترکیبات با روش¬های ir، nmr و بلورشناسی پرتو ایکس تعیین شده است. ویژگی¬های اتصال این ترکیبات با ct-dna با استفاده از روش¬های طیف¬سنجی جذبی و فلورسانس و آزمایش دناتوره¬شدن دمایی dna مورد بررسی قرارگرفت. نتایج، نشان می¬دهد که هردو مشتق فنازین از طریق اتصال بین¬لایه¬ای به ct-dna متصل می¬شوند،...
Linear–dendrite copolymers containing hyper branched poly(citric acid) and linear poly(ethylene glycol) blocks PCA–PEG–PCA are promising nonmaterial to use in nanomedicine. To investigate their potential application in biological systems (especially for drug carries) ONIOM2 calculations were applied to study the nature of particular interactions between drug and the polymeric nanoparticle...

Background: Male infertility has many causes, including genetic infertility. The NOP2/Sun domain family, member7 (Nsun7) gene, which encodes putative methyltransferase Nsun7, has a role in sperm motility. The aim of the present study was to investigate the effect of the T26248G polymorphism on Nsun7 protein function and its role in male infertility. Materials and Methods: Semen samples were col...
The sensitivity of the calculated matter radius to the binding energy is exploited to estimate the 2n binding energy of 22C, using a recent experimental value of Rm=5.4(9) fm. The result is B2n < 220 keV, significantly smaller than another recent estimate. Disciplines Physical Sciences and Mathematics | Physics Comments Fortune, H. T. and Sherr, R. (2012). Binding Energy of 22C. Physical Review...
