Nickel–molybdenum (Ni–Mo) materials are widely used functional oxide catalysts for the hydrogen evolution reaction. In this work, we investigate the high activity of Ni–Mo by depositing size-controlled Ni nanocrystals (NCs) onto Mo substrates. We observe a synergistic increase in catalytic activity that does not scale with the Ni–Mo interface length. This evidence points to a bulk electronic in...

There are many roles for electromechanical devices in image guided surgery. One is to help a surgeon accurately follow a preoperative plan. Devices for this purpose may be localizers, robots, or recently, synergistic systems in which surgeon and mechanism physically share control of the surgical tool. This paper discusses available technologies, and some emerging technologies, for guiding a sur...

The inhibitive ability of 2,6-diaminopyridine, tartaric acid and their synergistic effect towards mild steel corrosion in 0.5 M HCl solution was evaluated at various concentrations using potentiodynamic polarization measurements, electrochemical impedance spectroscopy (EIS), and weight loss experiments. Corresponding surfaces of mild steel were examined by atomic force microscope (AFM), field e...

Selaginella tamariscina is a traditional herb used in medicine. Phytochemical amentoflavone, a biflavonoid class of flavonoids, was isolated from the plant of Selaginella tamariscina. In this study, the antibacterial effects and combination effects of amentoflavone and conventional antibiotics such as ampicillin, cefotaxime, and chloramphenicol were investigated. These results showed that ament...

Combination of phenethyl isothiocyanate (PEITC) and paclitaxel (taxol) has been shown to work synergistically to increase apoptosis and cell cycle arrest in breast cancer cells. In this report, we further explored the mechanisms for the synergistic activity of PEITC and taxol in MCF7 and MDA-MB-231 (MB) breast cancer cell lines. By Western blotting analysis, treatment of MCF7 cells with both PE...

alismatis rhizoma decoction (ard) is a classical traditional chinese medicine (tcm) formula for treatment of vertigo with its long history of successful clinical effect. since vertigo is a symptom of hyperlipidemia, this study aimed at evaluating the hypolipidemic effect of ard in hyperlipidemia mice induced by high fat diet (hfd) and investigated the rationality of formula combination of alism...

Monotherapy remains the standard initial therapy of epilepsy, but when the first antiepileptic drug (AED) fails, combination therapy may be considered. The choice of combination therapy should take into consideration pharmacokinetic interactions, as well as pharmacodynamic interactions related to mechanism of action. There is evidence that an AED combination with different mechanisms of action ...

The curative effects of Chinese herbal compounds result from the coordination of numerous natural compounds. We aimed to review the mechanism of action of Traditional Chinese Medicine (TCM) compounds (TCMC), explore the rationality of formulation theory and synergistic effects in TCM compounds, and analyze the effectiveness of drug compatibility of TCMC in molecular biology. This literature rev...

A series of experiments evaluated the antileukemic effect of an agent which elevates cellular cyclic adenosine 3':5'-monophosphate levels by inhibiting phosphodiesterase. When ad ministered alone, theophylline had only modest antileukemic effects, but it had synergistic effects when administered with 1,3-bis(2-chloroethyl)-1 -nitrosourea. This synergism produced an improved therapeutic index in...
