Ulcerative colitis (UC), one of the two main types of inflammatory bowel disease, has no effective treatment. Rosmarinic acid (RA) is a polyphenol that, when administered orally, is metabolised in the small intestine, compromising its beneficial effects. We used chitosan/nutriose-coated niosomes loaded with RA to protect RA from gastric degradation and target the colon and evaluated their effect on acute colitis induced by 4% dextran sodium sulphate (DSS) for seven days in mice. RA-loaded nanovesicles (5, 10 and 20 mg/kg) or free RA (20 mg/kg) were orally administered from three days prior to colitis induction and during days 1, 3, 5 and 7 of DSS administration. RA-loaded nanovesicles improved body weight loss and disease activity index as well as increased mucus production and decreased myeloperoxidase activity and TNF-α production. Moreover, RA-loaded nanovesicles downregulated protein expression of inflammasome components such as NLR family pyrin domain-containing 3 (NLRP3), adaptor protein (ASC) and caspase-1, and the consequent reduction of IL-1β levels. Furthermore, nuclear factor erythroid 2-related factor 2 (Nrf2) and heme oxygenase-1 (HO-1) protein expression increased after the RA-loaded nanovesicles treatment However, these mechanistic changes were not detected with the RA-free treatment. Our findings suggest that the use of chitosan/nutriose-coated niosomes to increase RA local bioavailability could be a promising nutraceutical strategy for oral colon-targeted UC therapy.

The aim of this study was to analyze the biological behavior and osteogenic potential of magnesium (Mg) substituted hydroxyapatite (HA) microspheres, implanted in a critical bone defect, considering that this ion is of great clinical interest, since it is closely associated with homeostasis and bone mineralization. For the purpose of this study, 30 rats were used to compose three experimental groups: GI - bone defect filled with HA microspheres; GII - bone defect filled with HA microspheres replaced with Mg; GIII - empty bone defect; evaluated at biological points of 15 and 45 days. The histological results, at 15 days, showed, in all the groups, a discrete chronic inflammatory infiltrate; biomaterials intact and surrounded by connective tissue; and bone neoformation restricted to the borders. At 45 days, in the GI and GII groups, an inflammatory response of discrete granulomatous chronic type was observed, and in the GIII there was a scarce presence of mononuclear inflammatory cells; in GI and GII, the microspheres were seen to be either intact or fragmented, surrounded by fibrous connective tissue rich in blood vessels; and discrete bone neoformation near the edges and surrounding some microspheres. In GIII, the mineralization was limited to the borders and the remaining area was filled by fibrous connective tissue. It was concluded that the biomaterials were biocompatible and osteoconductive, and the percentage of Mg used as replacement ion in the HA did not favor a greater bone neoformation in relation to the HA without the metal.

Pesquisadas repercussões neonatais do tratamento crônico com inibidores seletivos de recaptura da serotonina (ISRS) sobre crescimento somático, do encéfalo e crânio. Ratos machos foram divididos em grupos: controle (NaCl) e Cit (10 µL/Kg citalopram 10 mg). Durante 21 dias pós-natais, foram aferidos peso corporal, eixo látero-lateral, ântero-posterior e circunferência do crânio. Aos 8, 15 e 22 dias pós-natais, os animais foram sacrificados para retirada do encéfalo para avaliar as medidas citadas acima. A utilização de ISRS provocou déficit de crescimento corporal, diminuição das medidas craniais e do encéfalo. O retardo é possivelmente decorrência de alteração na magnitude da ação trófica da serotonina sobre morfogênese crânio-facial, reforçando a participação do sistema serotoninérgico sobre o crescimento somático e ontogenético. O possível efeito hipofágico dos ISRS não é descartado.

Introdução: A abordagem multiprofissional durante o período gestacional inclui ações de educação alimentar e nutricional, tendo em vista que o estado nutricional adequado e uma alimentação saudável são fundamentais para a eficácia do sistema imunológico e prevenção de doenças crônicas e infecciosas. Objetivo: Relatar a experiência das autoras no aconselhamento nutricional de um grupo de gestantes, por meio do aplicativo WhatsApp®, no período de pandemia por SARS-CoV-2. Metodologia: Trata-se de um estudo descritivo, qualitativo, do tipo relato de experiência sobre a ação de extensão universitária desenvolvida pelo projeto “Aconselhamento Nutricional de Gestantes em Tempos de Covid-19”, realizado no período de junho a dezembro de 2020. Resultados: Participaram do grupo 28 mulheres em diferentes períodos da gestação. Foram realizadas 24 sessões grupais, com duração de duas horas semanais. A experiência foi avaliada na perspectiva das estudantes de Nutrição, docentes e gestantes que participaram do projeto, especialmente, no que tange à oportunidade de reconhecer os limites, as potencialidades e os desafios do aconselhamento nutricional on-line de grupos. Conclusões: A interação com as gestantes possibilitou o diálogo com a equipe do projeto e direcionou a trajetória metodológica, tornando as gestantes agentes ativas da prática assistencial.
