“…Nitroprusside plays its role through the production of compounds involved in detoxification of H 2 O 2 and antioxidant enzymes such as catalase (CAT), peroxidase (POD), ascorbate peroxidase (AXP), and guaiacol peroxidase (GPOX) (Tewari et al, 2006). NO has been found to reduce Pb uptake in Arabidopsis thaliana, thereby reducing toxicity symptoms (Phang et al, 2011). It also influences gene expression in response to oxidative stress in Zea mays leaves (Hermes et al, 2011).…”

This research investigated the effects of exogenous sodium nitroprusside (SNP) supplementation as nitric oxide (NO) on alleviating Pb-induced oxidative damage in lemon balm (Melissa officinalis L.) plants. Pb (100, 300 and 500 μM) alone and in combination with SNP (100 and 200 μM) were given to hydroponically grown Melissa officinalis L. plants. The findings suggested that in Pbtreated plants, height, total dry weight, and chlorophyll content of leaves markedly decreased while application of 100 μM SNP alleviated the inhibitory effect of Pb on plant growth and chlorophyll content. Pb exposure caused oxidative stress by elevating lipid hydroperoxide contents of the seedlings. Application of 100 μM SNP counteracted Pb toxicity by reducing lipid hydroperoxide contents of Pbtreated seedlings. Furthermore, it was found that the activities of antioxidant enzymes such as polyphenol oxidase, catalase, guaiacol peroxidase, and ascorbate peroxidase were increased in Pb-treated plants. The use of NO especially at low concentrations reversed Pb-induced negative effects whereas high concentrations of NO had no obvious alleviating effect on Pb toxicity in Melissa officinalis L. On the other hand, application of 100 μM SNP could function as a defense mechanism of the plant against Pb toxicity and mitigate Pb stress.

The high demand by the industry for graduates capable to critically analyze the causes, content and quality of information and using them effectively to identify and solve engineering problems, has been constantly and incessantly discussed. The inability to think analytically and critically contributes to the increased percentage of unemployed graduates. Additionally, the Malaysian students resort to memorizing and rote learning to find an easy way to get a degree and then find a job. This paper investigates the level of critical and analytical thinking skills among the students in the Department of Electrical, Electronics and Systems Engineering (EESE), Faculty of Engineering and Built Environment (FEBE), UKM. This study was conducted on a group of third year students in Semester 1 2010/2011 using three instruments; the analytical component of MTest model questions by the Malaysian Ministry of Education (MOE) in the selection of prospective students for Teachers College throughout the country, Marbach-Ad and Sokolove's taxonomy (MST) for student questions on a topic discussed in the lecture and the open-ended question posed in the final examination for the microprocessor and microcontroller course. Analysis based on these three techniques provide a rough estimation on the level of analytical and critical thinking skills among students and in this study, it was learned that the critical and analytical thinking skills among these students are at a very moderate level despite their high academic achievement.
