Metal ions in unusual valency states

Metal Ions in Neuroscience

Metal ions are believed to participate in many neurodegenerative conditions. In excitotoxic cell death there is convincing evidence for the participation of Ca(2+) and Zn(2+) ions although the exact molecular mechanisms by which these metals exert their effects are unclear. Only in one instance has the metal binding site of metalloenzymes been exploited for therapeutic purposes and this is the ...

application and construction of carbon paste modified electrodes developed for determination of metal ions in some real samples

ساخت الکترودهاِی اصلاح شده ِیکِی از چالشهاِی همِیشگِی در دانش شیمِی بوِیژه شیمِی تجزیه مِی باشد ،که با در نظر گرفتن سادگِی ساخت، کاربردی بودن و ارزان بودن روش مِی توان به باارزش بودن چنِین سنسورهاِی پِی برد.آنچه که در ادامه آورده شده به ساخت و کاربرد الکترودهاِی اصلاح شده با استفاده از نانو ذرات در اندازه گِیرِی ولتامترِی آهن وکادمِیم اشاره دارد. کار اول اختصاص دارد به ساخت الکترود خمِیر کربن اصلاح شده با لِیگاند داِ...

VALENCY and MT: Recent Developments In The METAL System

This paper describes a valency model, developed within the Belgian METAL project, aimed at enhancing the modularity and multilinguality of the METAL system. The introduction provides background, section 1 discusses the existing valency framework, and section 2 presents the alternative model. The final section deals with some results and problems with this model.

Metal Ions in Stroke Pathophysiology

Y.V. Li and J.H. Zhang (eds.), Metal Ion in Stroke, Springer Series in Translational Stroke Research, DOI 10.1007/978-1-4419-9663-3_1, © Springer Science+Business Media New York 2012 Abstract Metal ions are used in biology in many ways and are integrated parts of numerous enzymes and proteins. They function as cofactors in cellular and genetic signaling and, therefore, have important roles in b...
