Khyzer Ehtisham, Aftab Tehreem.' Perceptions about Current Use, Effectiveness and Barriers in Implementation of Interactive Learning at College Of Medicine, Northern Border University, Arar

Objectives: To understand the perceptions of medical students about the current use of interactive learning, its effectiveness and barriers in its implementation. Method: A cross-sectional study was carried out at the College of Medicine, Northern Border University, Arar, Kingdom of Saudi Arabia. Study participants were fifth and final year medical students. A semi-structured questionnaire was used to collect the information in relation to perceptions regarding the use of interactive learning, its effectiveness, and barriers. The questionnaire consisted of Likert scale ranking and close-ended questions. The student’s response was analyzed by frequency analysis. Results: A total of 150...

Knowledge and attitude about stem cells and their potential applications in field of medicine among medical students of arar, Saudi Arabia.

Author(s): AFTAB, TEHREEM; KHYZER, EHTISHAM Abstract: Introduction: The use of stem cell has opened new avenues in the management and cure of diseases in modern era. They have enabled us to achieve remissions and cure in malignancies. They have enormous ability of stimulating the repair process in diseased and damaged tissue. As the medical specialists are a reliable source of information, so their knowledge and approach are vital in counselling the patients regarding the use of stem cells as an advanced treatment option. Aim: To assess the knowledge and attitude level about stem cells and their...

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...

Fault-Recovery and Robust Deadlock Control of Reconfigurable Multi-Unit Resource Allocation Systems Using Siphons

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...

Modeling and Deadlock Control of Reconfigurable Multi-Unit Resource Systems

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...
