Melatonin (N-acetyl-5-methoxytryptamine) has emerged as a new growth regulator in plants due to its positive role in alleviation of abiotic stresses. The regulation effect of melatonin in mediation of salinity stress on antioxidative activities, growth and yield of wheat plants was investigated using genotypes Sarsabz and S-24, grown under 10 dSm -1 NaCl salinity stress. Different concentrations of melatonin (50, 100, 300 and 500 µM) were applied foliarly after 45 days of sowing (DAS). Results revealed that melatonin under salinity stress significantly improved the growth and yield of both wheat genotypes as compared to non-treated ones. The yield was enhanced to 5 and 11% by 50 µM melatonin in both wheat cultivars respectively, which increased further 44 and 48% at 500 µM melatonin level in Sarsabz and S-24 respectively, as compared to salinity alone treatment. Furthermore, foliar spray of melatonin was effective in improving the activities of catalase, peroxidase and superoxide dismutase under stress conditions in wheat genotypes. The application of 500 μM melatonin was more effective in reducing the oxidative damage under salinity stress in terms of activities of antioxidant enzymes with an alternate decrease in malondialdehyde content. The increased activities of antioxidant enzymes are positively related with an enhanced biomass production and yield showing the ameliorative effect of melatonin under salt stress condition by up regulating the antioxidative defense mechanism. Results suggested that the foliar application of melatonin can be a useful strategy to help plant combat adverse conditions for enhancing yield of wheat plants.
Dear Madam, Imposter syndrome is defined as the psychological experience in which one believes that their accomplishments were purely due to chance and not based on merit(1). It is no shock that this phenomenon is common in a highly competitive and intellectually demanding medical career. This syndrome not only strives amongst medical students, but also amongst physicians far ahead in their careers(2).
A recent study has demonstrated that mental illnesses and their associated phenomena are present in 21.0% of the adults in the United States(3). The results of this study are a reason for concern, especially amongst students in Pakistan, where experiences such as the imposter syndrome contribute to the already poor mental health and access to mental health treatments(4). This form of self-doubt results in a decline in emotional paralysis and a decline in productivity and confidence(5).
A detailed online literature search on PakMediNet and PubMed surprisingly resulted in no articles addressing the occurrence of imposter syndrome and its adverse effects on Pakistani students, demonstrating the severe lack of attention given to this phenomenon. Medical students exhibit high-stress levels and self-doubt(6), but no diagnosis is ever reached. Therefore, the need of the hour is to conduct studies regarding imposter syndrome in medical schools. Since the field of medicine is highly romanticized in Pakistan, people are not enlightened regarding these aspects among medical students, especially the ones in top medical schools, as well as the high achievers.
Furthermore, it is pivotal for medical institutions to bring forth and initiate programs that empower the members of the healthcare profession to recognize and address this phenomenon. In addition, easy access to therapy and/or counselling sessions provided by medical educational programmes shall allow medical students to enhance their overall mental health. It shall contribute to decreasing cases of psychological illness and social isolation. Medical educators must also realize that it is not only the underperforming learner who struggles and needs support but also those who are far ahead in their medical careers. The participation of parents is also imperative; they must be made aware of this syndrome to allow them to identify the possible signs of the syndrome on a personal level. Encouraging students to celebrate their successes, share their thoughts, and accept the presence of the imposter syndrome will promote a healthier social and academic lifestyle producing good quality members of the healthcare system of Pakistan.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
