This study aimed to evaluate the effects of the treatment with bacuri seed butter (BB) on body weight, growth, body mass index, lipid profile, atherosclerotic indices, and liver function in dyslipidemic hamsters. Freshly weaned, male hamsters were divided into four groups: (1) normal group (NG)—maintained with standard chow (AIN-93G); (2) dyslipidemia group (DG)—maintained with hyperlipidemic chow (AIN-93G modified) throughout the follow-up period; (3) bacuri seed butter 25 mg/kg/day (BB-25); and (4) bacuri seed butter 50 mg/kg/day (BB-50). BB groups (25 and 50 mg/kg/day) were also maintained with hyperlipidemic chow throughout the follow-up period, and the treatment started after 21 days receiving a hyperlipidemic diet to induce hypercholesterolemia and maintained for 28 days. No significant differences in triglycerides and total cholesterol were observed for BB-25 and BB-50 groups when compared with NG and DG groups. On the contrary, BB-25 and BB-50 induced both increase of HDL-c (51.40 ± 1.69 and 51.00 ± 2.34, respectively) and decrease of LDL-c (103.80 ± 6.87 and 100.50 ± 3.95, respectively) when compared with DG (41.00 ± 2.94 and 132.70 ± 9.41, respectively). In addition, BB promoted a reduction in the risk of atherosclerotic disease by decreasing p < 0.05 the atherogenic index, coronary artery risk index, and LDL/CT ratio p < 0.05 and increasing HDL/CT ratio. On the contrary, no changes were observed in total cholesterol and triglyceride levels or in body weight, growth, body mass index, or liver function parameters. Thus, bacuri seed butter at doses of 25 and 50 mg/kg/day has positive repercussions on the lipid profile, more precisely on plasma HDL-c and LDL-c, and additionally promotes reduction in the risk of atherosclerosis in hamsters.

Leishmaniasis is an infectious disease that affects millions of people worldwide, making the search essential for more accessible treatments. The species Platonia insignis Mart. (Clusiaceae) has been extensively studied and has gained prominence for its pharmacological potential. The objective of this work was to evaluate the antileishmania activity, cytotoxic effect and activation patterns of macrophages of hydroalcoholic extract (EHPi), ethyl acetate fractions (FAcOEt) and morelloflavone/volkensiflavone mixture (MB) from P. insignis flowers. EHPi, FAcOEt and MB demonstrated concentration-dependent antileishmania activity, with inhibition of parasite growth in all analyzed concentrations. EHPi exhibited maximum effect at 800 μg/mL, while FAcOEt and MB reduced the growth of the parasite by 94.62% at 800 μg/mL. EHPi, FAcOEt and MB showed low cytotoxic effects for macrophages at 81.78, 159.67 and 134.28 μg/mL, respectively. EHPi (11.25 µg/mL), FAcOEt (11.25 and 22.5 µg/mL) and MB (22.5 µg/mL) characterized the increase in lysosomal activity, suggesting a possible modulating effect. These findings open for the application of flowers from a P. insignis flowers and biflavones mixture thereof in the promising treatment of leishmaniasis.

Bacuri (Platonia insignis) is a monotype belonging to the Clusiaceae family. Of Amazonian origin, it is highly appreciated for fresh consumption, mainly due to its peculiar sensory characteristics. It is also widely used in the food industry, mainly in pulp (endocarp), used in the manufacture of beverages, jellies, and ice cream. Although the use of pulp is well established in the food sector, recently, research has turned attention to the use of other parts of the fruit and plant, especially in the therapeutics, cosmetics, and fuel sectors. Its bioactive components have been investigated for having important antioxidant, anti-inflammatory, immunomodulatory, hypotensive, cardioprotective, antiepileptic, antileishmanial, and antifungal activities, among others, mainly attributed to the presence of compounds such as xanthones, terpenes, phenolics, and fatty acids. Thus, this study aimed to gather data on the species Platonia insignis Mart. through an integrative review of the agronomic, nutritional, physical–chemical characteristics and a technological prospection about its applications. The study showed that in the last ten years there has been a significant increase in the number of patents deposited, with the prospect that with the advancement of studies on their properties, results for application in the most diverse areas will prove increasingly viable and promising.

As doenças de origem alimentar são caracterizadas pela ingestão de alimentos e/ou água, com a presença de contaminantes (químicos, físicos ou biológicos) que chegam até o organismo e afetam a saúde de forma individual ou em grupo. Entre os principais causadores dessas doenças, destacam-se os micro-organismos e suas toxinas, que podem contaminar os alimentos durante toda a cadeia produtiva, podendo chegar ao consumidor principalmente quando os processos de manipulação e higiene são realizados de forma inadequada. A preocupação com os processos higiênicos merece especial atenção quando os alimentos são para consumo in natura, como ocorre habitualmente com frutas e hortaliças. Comumente são relatados a presença de contaminação desses alimentos por bactérias patogênicas, especialmente Salmonella spp., Listeria spp., Escherichia coli e estafilococos aureus. Desta forma, esta pesquisa buscou identificar os principais fatores que contribuem para a contaminação de frutas e hortaliças nas diferentes fases da cadeia produtiva por meio de um estudo de revisão, com foco nas bactérias patogênicas. As informações reunidas contemplam ainda uma discussão sobre a legislação vigente sobre o tema e sua importância para o fornecimento de um alimento seguro para consumo.
