We define equivariant asymptotic morphisms between C 0 ðX Þ-algebras and construct the category of homotopy classes of such morphisms. Based on this category we construct the category of homotopy classes of asymptotic morphisms which are equivariant with respect to an action of a groupoid. We then define and study the corresponding equivariant E-theory. r

In this mini-review, we describe some of the latest facts regarding the generation of condensed base phonons by biological entities, initially described by the renowned contemporary physicist, Nobel laureate, Herbert Fr?hlich, who proposed a new biophysical interaction mechanism between extremely high frequency electromagnetic waves and the biological environment. As we will show, this extremely low intensity millimeter therapy crystallizes as an important new method, universal and effective in the management of diseases with different etiologies. Moreover, the existence of internal electromagnetic fields generated by biological entities, as well as external electromagnetic fields, are essential for understanding the electromagnetic-biological effect. In fact, it is estimated that at present millimeter-wave therapy is used for the management of more than 120 diseases in cardiology, neurology, oncology, gynecology, urology, gastroenterology, surgery, pharmacology and pediatrics. However, so far there is still no consensus regarding the interaction between extremely high frequency/extremely low intensity electromagnetic waves and the biological environment at its different levels of organization. Thus, the present paper was intended to contribute to the development for the theory of millimeter-wave interaction with living biological entities.

There is increased interest in the interactions between vascular disorders and Alzheimer?s disease (AD). While initially these interactions were explained by the fact that these are both very common disorders, particularly later in life, recently, the possibility that these deficiencies might actually coexist is increasingly being questioned. This review attempts to present modern aspects and current reports regarding the interactions between AD, the renin-angiotensin system (RAS) and hypertension, while also describing the relevance of antihypertensive drug use acting via the RAS in the treatment and prevention of AD, as well as the importance of oxidative stress, the alteration of the balance between antioxidants and pro-oxidants, in the interaction between AD and the RAS.

Lately there is a growing interest in the negative symptoms in schizophrenia and their mechanisms of action, with special focus on the motivation process. The lack of motivation is increasingly recognized to be a very important impediment to positive management in schizophrenic pathology. In this mini-review, we described the current understanding of the nature and causes of the specific motivational deficits in schizophrenia in order to find better management strategies for this heterogeneous disorder. All the data and theories presented here clearly demonstrate that amotivation is a fundamental aspect of the negative symptomatology in schizophrenia and could represent a useful factor in understanding and improving the mechanisms and further management of schizophrenia.

While the exact relevance of the oxidative stress markers after the complex processes of alcohol withdrawal is still controversial, in the present report we were interested in studying the relevance of oxidative stress status in the alcohol withdrawal processes, by determining some oxidative stress markers after 3, 6 and 12 months of abstinence. 62 patients were selected, all of them males. Thus, 33 (baseline), 14 (3 months), 14 (6 months)
