Objective Chronic unpredictable stress (CUS) can influence the risk and progression of cancer through increased oxidative stress. Quercetin (QU), a phytochemical found in daily foods, has been extensively studied as a chemopreventive agent against various types of cancers. Our aim was to investigate the role of CUS on the efficacy of QU against DMBA+TPA (7, 12-dimethylbenz (a) anthracene+12-O-Tetradecanoylphorbol-13-acetate)-induced skin carcinogenesis. Methods Eighty-four adult male Swiss albino mice were randomly divided into seven groups (12 mice/group) based on different treatments and killed after 16 weeks. Blood and skin tissues were collected for biochemical estimations, DNA damage...

A multi-unit resource allocation system usually contains several processes and a number of resources with multiple units. Due to the competition for shared resources in these systems, deadlocks may occur. Recently, researchers have shown an increased awareness in deadlock control strategies for such a kind of systems without considering the dynamic changes such as processing failures and rework by using the Petri net paradigm. This article reports a new strategy for deadlock analysis and control in reconfigurable multi-unit resource systems (MRSs). We discuss a generalized class of Petri nets in which each stage of a process may require a number of units of different types of resources to...
Most existing methods for deadlock control in multi-unit resource systems are developed based on parallel multi-unit resource deadlock algorithms and their hardware implementation. However, the rapid dynamic changes in such resource allocation systems raise the following challenging problems: (a) how to model and control deadlocks in these systems in an alternative way as modeled by Petri nets, and (b) how to quickly and effectively make Petri nets able to adapt to these dynamic changes in such configurable systems. In order to cope with these problems, this study makes five contributions: (1) propose an efficient integrated policy for designing supervisors for multi-unit resource systems...
