Imatinib mesylate, a BCR/ABL fusion protein inhibitor, is the first-line treatment against chronic myelogenous leukemia. In spite of its advantageous viewpoints, imatinib still has genuine impediments like undesirable side effects and tumor resistance during chemotherapy. Nanoparticles with sustainable release profile will help in targeted delivery of anticancer drugs while minimizing deleterious side effects and drug resistance. The use of biopolymers like galactoxyloglucan (PST001) for the fabrication of imatinib mesylate nanoparticles could impart its use in overcoming multidrug resistance in chronic myelogenous leukemia patients with minimal side effects. This study involved in the synthesis of PST-Imatinib nanoconjugates with appreciable drug payload and excellent cytotoxicity against drug-resistant chronic myelogenous leukemia cell line (K562) in comparison with free drug. The use of bioinformatics tool revealed better binding affinity for the drug-polysaccharide complex than the drug alone with three proteins: 3QX3 (Topoisomerase), 1M17 (EGFR tyrosine kinase domain), and 3QRJ (ABL1 kinase domain). Assessment of the biochemical, hematological, and histopathological parameters in mice upheld the security and adequacy of the nanoconjugate compared to free drug. Although perspective investigations are warranted, in a condition like drug resistance in leukemia, this nanoconjugate would display a productive approach in cancer therapeutics.
Background: Survivors of disfiguring burn injury often become social handicaps. Therefore, it is of utmost importance to understand their perception of body image, their coping skills, their appraisals about social support and self-monitoring behaviour in social situations and explore the factors that can promote better psychological adjustment.Methods: Using a single group cohort design, a sample of 18 individuals with burn injury, were recruited through purposive sampling. Personal data sheet, self-monitoring scale (SMS) and satisfaction with appearance scale (SWAP) were administered when the patients were admitted post-injury. Social support appraisal scale (SSA), coping with burns questionnaire along with SMS and SWAP were administered at one-month post-discharge.Results: The findings indicated that gender and education played a significant role in body image, coping, social support appraisal and self-monitoring behaviours. Further, higher scores on coping strategies were associated with better body satisfaction.Conclusions: The findings indicate the need to look into the variables of coping, body image, social support, self-monitoring behaviours of burns patients and the need to develop interventions for improving their quality of life. A mixed-method study design for better understanding of the psychosocial factors impacting adjustment post-burn injury would be beneficial. Although a larger cohort needs to be studied for understanding the impact of these factors, one may already notice definite indicators that are risk factors that may lead to poorer psycho-social wellbeing of burn victims and potential areas where interventions may be effective.
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.
