Involvement of Polyphenol Compounds in Histamine Release Suppression by Pomegranate Vinegar

‏‎suppression of coke formation in thermal cracking by coke inhibitors‎‏

‏‎the main purpose of this research was to:1.develop a coking model for thermal cracking of naphtha.2.study coke inhibition methods using different coke inhibitors.developing a coking model in naphtha cracking reactors requires a suitable model of the thermal cracking reactor based on a reliable kinetic model.to obtain reliable results all these models shall be solved simultaneously.for this pu...

Effects of three steroidal compounds on oestrus suppression in queens

Pregnancy prevention raises much concern to many pet owners. Female cats usually show undesirable behaviour during oestrus. Nowadays, researchers try to explore the reliable and effective ways to prevent oestrus signs in queens. The results of their studies prove that hormone therapy is probably one of the most reliable methods for this purpose. The aim of our study was to compare the effect of...

comparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.

heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...

The release of histamine by sinomenine.

Sinomenine is an alkaloid contained in the root of Sinomenium acutum Rehd. et Wilson (Fam. Menishermaceae), growing wild in southern Japan, and has long been used as a home remedy for neuralgia and rheumatism. It has a chemical structure similar to that of morphine, as shown left (1). Ishiwari (2, 3), who first isolated this alkaloid and studied its pharmacological actions, found that sinomenin...
