A study on TETFUND projects in the Southeast found that project success and cost performance are crucial for building projects. The study used a census technique, questionnaires, and content validity to confirm the instrument's inclusivity and relevance to strategic leadership and project management sustainability. The study reveals that the cost of every project is important, regardless of funding, and that cost availability has hindered any TETfund project at State universities in South-East, Nigeria.The majority of respondents strongly agreed that cost determines whether a TETfund project is completed with or without a supervisor, and that cost gives contractors more chance of income during the TETfund project period. Furthermore, the cost of the project motivates workers to complete it within an appropriate period. The analysis shows that TETfund cost has a positive effect on the completion rate of projects across State Universities in SouthEast, Nigeria, with an average mean value of 3.65>3.00. The test of hypotheses showed that TETfund cost has no significant positive effect on the completion rate of projects across State Universities in South-East, Nigeria. The results showed that the model in this table has a statistically significant positive effect, and the alternate conclusion is accepted, as TETfund cost had a significant positive effect on the completion rate of the project across State Universities.","PeriodicalId":504624,"journal":{"name":"IAA Journal of Applied Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141031800","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Oxidative stress, resulting from an imbalance between reactive oxygen species (ROS) production and antioxidant defense mechanisms, has been implicated in various pregnancy complications. Antioxidants, renowned for their ability to counteract ROS and mitigate cellular damage, have emerged as a potential intervention to ameliorate adverse outcomes during pregnancy. The paper highlights the physiological changes in pregnancy that contribute to heightened oxidative stress, emphasizing the link between oxidative stress and complications such as pre-eclampsia, gestational diabetes, preterm birth, and intrauterine growth restriction. This paper emphasizes the imperative for robust, well-designed clinical trials to elucidate the optimal timing, dosages, and formulations of antioxidants in pregnancy. It calls for a comprehensive approach to establish clear guidelines and recommendations for antioxidant supplementation. In conclusion, this review underscores the potential of antioxidants as a promising intervention to mitigate oxidative stress-related pregnancy complications. However, the inconclusive nature of current evidence necessitates further rigorous research endeavors. Through this exploration, it accentuates the urgency for standardized protocols, ethical considerations, and extensive clinical studies to unlock the full potential of antioxidants in improving maternal and fetal health outcomes during pregnancy.
