Objective(s): In this study a series of novel colchicine-like β-acetamidoketones was designed and synthesized as potential tubulin inhibitorsMaterials and Methods: The cytotoxicity of the novel synthesized β-acetamidoketones was assessed against two cancerous cell lines including MCF-7 (human breast cancer cells) and A549 (adenocarcinomi...

We propose a new numerical method for one dimensional stochastic differential equations (SDEs). The main idea of this is based on representation weak solution an SDE using time-changed Brownian motion, which dates back to Doeblin (1940). In cases where the diffusion coefficient bounded and β-Holder continuous with 0<β≤1, we provide rate strong convergence. An advantage our approach that approxi...

Thermodynamic study on the interaction of β-CD with poly ethylene oxide and poly acrylic acid was performed by isothermal titration calorimetry at 298K. when β-CD is added to the interpolymer complex, competition is created between host-guest and Hydrogen bond. Enthalpy of interaction between the β-CD and interpolymer complex was calculated using the extended solvation theory. P=1 Shows that w...

Purification of a MeOH extract from the aerial parts of Hylomecon vernalis Maxim. (Papaveraceae) using column chromatography furnished a new acetylated flavonol glycoside (1), together with twenty known phenolic compounds (2-21). Structural elucidation of 1 was based on 1D- and 2D-NMR spectroscopy data analysis to be quercetin 3-O-[4‴-O-acetyl-α-L-arabinopyranosyl]-(1‴→6″)-β-D-galactopyranoside...

The objective of this study was to investigate the effect 1/f fluctuation wave on EEG α-α interval and stability cell membrane. We compared analyzed with different character signal slope in healthy men grey rabbits, studied Main outcome measures were gradient increased 142% by electromagnetic field 1.5 β value 135% sound impulse 1/f. After act, erythrocyte membrane osmotic resistance 34~38%. So...

We study the weak convergence of β- and β′-Delaunay tessellations in Rd−1 that were introduced part I this paper, as β→∞. The limiting stationary simplicial random tessellation, which is called Gaussian-Delaunay characterized terms a space-time paraboloid hull process Rd−1×R. latter object has previously appeared analysis number shocks solution inviscid Burgers’ equation description local asymp...

Two additional novel minor diterpene glycosides were isolated from the commercial extract of the leaves of Stevia rebaudiana Bertoni. The structures of the new compounds were identified as 13-{β-D-glucopyranosyl-(1 → 2)-O-[β-D-glucopyranosyl-(1 → 3)-β-D-glucopyranosyl-oxy} ent-kaur-16-en-19-oic acid {β-D-xylopyranosyl-(1 → 2)-O-[β-D-glucopyranosyl-(1 → 3)]-O-β-D-glucupyranosyl-ester} (1), and 1...
