ABSTRACT
Insects of different orders produce elaborate structures to protect their eggs from the many threats they may face from the environment and natural enemies. In the weevil genus Gonipterus, their dark, hardened egg capsule is possibly generated by a mixture of the insects' excrement and glandular substances. To test this hypothesis, this study focused on the elucidation of protein components present in the egg capsule cover and interrogated them through comparative analysis and gene expression to help infer potential functions. First, female Gonipterus sp. n. 2 reproductive and alimentary tissues were isolated to establish a reference transcriptome-derived protein database. Then, proteins from weevil frass (excrement) and egg capsule cover were identified through mass spectrometry proteomics. We found that certain egg capsule cover proteins were both exclusive and shared between frass and egg capsule cover, including those of plant origin (e.g. photosystem II protein) and others secreted by the weevil, primarily from reproductive tissue. Among them, a mucin/spidroin-like protein and novel proteins with repetitive units that likely play a structural role were identified. We have confirmed the dual origin of the egg capsule cover substance as a blend of the insects' frass and secretions. Novel proteins secreted by the weevils are key candidates for holding the egg case cover together.
ABSTRACT
PURPOSE: To compare the nutritional status follow up of patients who underwent Roux-en-Y gastric bypass (BGYR) and Sleeve gastrectomy (SG) in hospitals of the private and public health systems, in Pernambuco. METHODS: This study included patients who underwent bariatric surgery in the public and private health systems, in Pernambuco, from 2008 to 2016. Anthropometric and biochemical (hemoglobin, B12, iron and ferritin) data were evaluated in the preoperative period and at 3, 6 and 12 months after the operation. RESULTS: There were no significant difference between patients seen at the two health systems regarding the levels of hemoglobin, iron, anemia and vitamin B12. Patients who underwent the RYGB, presented with iron deficiency which was significantly lower for those in the private system, but only at the 3 month evaluation. Low levels of ferritin were observed at the 6 month evaluation, and patients in the private health system presented with the highest ferritin deficiency. The rate of surgical success was significantly higher in those patients undergoing the RYGB at the private system. CONCLUSIONS: After a 12-month bariatric surgery follow-up, there was no statistically significant difference regarding micronutrient deficiency between patients followed up at the private and public health systems.
OBJETIVOS: Comparar a evolução do perfil nutricional de pacientes submetidos ao bypass gástrico em Y de Roux (BGYR) e ao Sleeve, em hospitais dos setores público e privado da Saúde de Pernambuco. MÉTODO: O estudo incluiu pacientes submetidos à cirurgia bariátrica nos setores público e privado de saúde de Pernambuco no período de 2008 a 2016. Foram avaliados dados antropométricos e bioquímicos (Hemoglobina, Vitamina B12, Ferro e Ferritina) no período pré-operatório e com 3, 6 e 12 meses de pós-operatório. RESULTADOS: Não foram registradas diferenças significativas entre os pacientes internados nos dois setores da Saúde no tocante às variáveis: níveis hemoglobina, anemia por deficiência de ferro e vitamina B12 em nenhuma das avaliações e conforme o tipo de cirurgia. Entre os pacientes submetidos ao BGYR, os níveis de ferro sérico foram significativamente menores nos pacientes do setor privado da Saúde apenas na primeira avaliação. Baixos níveis de ferritina sérica foram observados na segunda avaliação, sendo os pacientes do setor privado os que apresentaram menores valores. O sucesso cirúrgico foi significativamente maior no grupo que realizou o BGYR na rede privada. CONCLUSÕES: Com um seguimento de 12 meses pós-cirurgia bariátrica, não foi observada diferença estatisticamente significante no que diz respeito às deficiências de micronutrientes entre pacientes usuários dos setores público e privado de Saúde.
