Hydroxyl free radical production seems to play an important role in the pathogenesis of Parkinson's disease. In the present study, we investigated the dopamine agonists pramipexole and pergolide as well as the nitrone compound S-PBN (N-tert-butyl-alpha-(2-sulfophenyl)nitrone) to reduce hydroxyl radical formation. Microdialysis experiments were carried out in non-anaesthetized Wistar rats. Salic...

Asthmatic patients are more subjected to continuous oxidative stress. Roosting the antioxidant defenses of asthma patient could be beneficial as it may help thwart symptoms of the lung disease and asthma. Considering these facts different plant extracts and phytoconstituents with proven anti asthmatic property had been subjected to antioxidant study at various combinations using Diphenyl Vicryl...

The radical-scavenging activity of dietary phytophenols has been investigated by many researches due to their antioxidant, anti-inflammatory and anticancer property but the radical-scavenging effect of 2-phytophenol and the phytophenol:co-antioxidants, vitamin C and thiol combination under nearly anaerobic conditions still remains unknown. The radical-scavenging activity for seventeen phytophen...

BACKGROUND tudy describes antioxidant and anti-inflammatory properties of Sauropus androgynus leaf dialysed protein extract. Free radicals are implicated for many diseases including diabetes mellitus, arthritis, cancer, ageing etc. In the treatment of these diseases, antioxidant therapy has gained utmost importance. The main objective of the present study was to reveal the antioxidant and anti-...

Abstract In a Banach algebra A it is well known that the usual spectrum has following property: $$\begin{aligned} \sigma (ab) \setminus \{0\} = (ba) \end{aligned}$$ σ ( a b ) \ {</mml:m...

Iron is a ubiquitous constituent of cytochromes, oxygen-binding molecules and a variety of enzymes because of its property to transition from ferric (Fe3+) to ferrous (Fe2+) state, leading to change in the redox potential. However, the same property accounts for free radical injury. In order to overcome harmful effects of iron we investigated the possible protective effect of quercetin (QCT), a...

We give a criterion for when idempotents of a ring R which commute modulo the Jacobson radical J(R) can be lifted to commuting idempotents of R. If such lifting is possible, we give extra information about the lifts. A “half-commuting” analogue is also proven, and this is used to give sufficient conditions for a ring to have the internal exchange property. In particular, we show that if R/J(R) ...

Let $alpha$ be an automorphism of a ring $R$. The authors [On skewinverse Laurent-serieswise Armendariz rings, Comm. Algebra 40(1)(2012) 138-156] applied the concept of Armendariz rings to inverseskew Laurent series rings and introduced skew inverseLaurent-serieswise Armendariz rings. In this article, we study on aspecial type of these rings and introduce strongly Armendariz ringsof inverse ske...
