In the last 100 years major depression has increased worldwide. In this study we provided coconut fat (CF, rich in saturated fatty acids) or fish oil (FO, rich in n-3 polyunsaturated fatty acids) to female rats throughout pregnancy and lactation and then to their offspring post-weaning and examined lipid brain profile and the possible effect of FO as antidepressant agent in the offspring in adulthood (F1). Rats were submitted to forced swimming test, elevated plus maze, Morris water maze and open field. Peroxidation rate in the cerebral cortex and hippocampus were measured. Docosahexaenoic acid (DHA) concentration in dam's milk, eicosapentaenoic acid (EPA) and DHA concentration in hippocampus and cerebral cortex from F1 rats FO supplemented increased significantly when compared to control (C) and CF rats. Arachidonic acid/EPA ratio in the cerebral cortex and hippocampus decreased in rats submitted to forced swimming test. Peroxidation rate were not different between the groups. Immobility time in the forced swimming test in FO group was reduced (p < 0.01) when compared to C and CF rats. We conclude that lifelong intake of FO was able to induce an antidepressant effect with EPA and DHA concentration increased in the cerebral cortex and hippocampus.
There was a high prevalence of oral leukoplakias in patients with Fanconi anaemia who had not undergone HSCT. It highlights the need of regular oral screenings in this cohort of concern for head and neck malignancies and suggests that oral leukoplakias should be further investigated as part of the syndrome phenotype.
Fanconi anemia (FA) is a genetic disease that is characterized by several congenital abnormalities and progressive bone marrow failure and is associated with an increased susceptibility to malignant disorders. Currently, the only potential cure for hematological disorders is hematopoietic stem cell transplantation (HSCT). However, 1 of the most common complications after HSCT is the development of oral chronic graft-versus-host disease (cGVHD), which is also a risk factor for the development of cancer, particularly oral squamous cell carcinoma. Therefore, the purpose of this study was to describe the prevalence and characteristics of oral manifestations compatible with cGVHD in patients diagnosed with FA according to the National Institutes of Health (NIH) consensus criteria. A total of 96 patients (51 females, 45 males; median age, 16 years) with FA, who were in medical follow-up after HSCT at the outpatient clinic of the bone marrow transplantation unit (Hospital de Clínicas from the Universidade Federal do Paraná) underwent an oral evaluation between January 2013 and December 2013. Post-HSCT periods varied from 1 to 261 months and were divided into 3 periods: immediate post-HSCT period; intermediate post-HSC period, and late post-HSCT period. Among the evaluated patients, 40 of 96 (42%) presented with oral manifestations of cGVHD, with 29 of 40 (73%) of these patients in the late post-HSCT period. NIH scale scores varied from 0 to 10, and lichenoid and hyperkeratotic lesions were the abnormalities most frequently observed (100%). Overall, a high prevalence of oral manifestations was observed for cGVHD patients with FA. These data highlight the importance of monitoring oral manifestations compatible with cGVHD to identify and treat individuals with a higher risk of developing oral cancer.
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.
