Hydroethanolic Extract of Solanum paniculatum L. Fruits Modulates ROS and Cytokine in Human Cell Lines.

Solanum paniculatum L. or popularly known as "jurubeba" is an herbal medicinal plant. A few studies have investigated its biological effects; however, research aimed at elucidating the redox balance effects from its fruits has not been reported so far. ROS interplays in various fields of medicine such as chemotherapy. Here, we evaluated antioxidant and inflammatory activities of the hydroethanolic extract of Solanum Paniculatum L. (HESPL) fruits in breast cancer cells, as well as its phytochemical profile. The antioxidant profile (carotenoids and phenolic compounds) was obtained by HPLC-DAD-UV and HPLC-APCI-MS. Cancer cell lines and human vein endothelial cells (HUVECs) were cultivated and treated with 1.87-30 µg/mL of HESPL for 24 hrs. Cytotoxicity, oxidative, and inflammation biomarkers were evaluated. The dose of 30 µg/mL of the HESPL extract presented cytotoxicity in the MCF-7 cell line. However, for MDA-MB-231, the cytotoxicity was observed in the dose of 1.87 g/mL. The 1.87 µg/mL and 3.75 µg/mL doses decreased the concentration of IL-6 in MCF-7 cells. In the MDA-MB-231 cells, the HESPL did not decrease the IL-6 concentration; however, in the doses of 15 and 30 µg/mL, an increase in this parameter was observed. The HESPL increased IL-1ß concentration in HUVECs. The ROS level in MCF-7 was elevated only at the 30 µg/ml dose. Regarding MDA-MB-231, HESPL promoted increased ROS levels at all doses tested. HUVEC showed no increase in ROS under any dose. HESPL treatment may modulate cytotoxicity, ROS, and cytokine levels due to its phytochemical profile, and it has shown an antioxidant or anti-inflammatory effect.

Prevalence of metabolic syndrome and associated factors in adults living in Fernando de Noronha, Brazil.

Metabolic Syndrome (MetS) is multivariate disease, clustered with socioeconomic and behavioral risk factors. Investigations about epidemiology estimative could be a prevention strategy. AIM: to investigate the prevalence of metabolic syndrome and its associated factors in adult population in Fernando de Noronha Archipelago (PE-Brazil). METHODS: A cross-sectional study was performed on a representative sample (N = 375) of adult residents of the region, aged 24-59 years, were harmonized according to the International Diabetes Federation (IDF) criteria. RESULTS: The prevalence of metabolic syndrome was 45 (12%) and, the age was associated with MetS, which increases the chances to MetS development around 3% respectively (OR: 1.03; CI 95%: 1.002-1.070 P 0.0384). Waist circumference was elevated in female population 266 (70.74%), however, levels of fasting blood glucose (304 [80.85%]), blood pressure (375 [100%]), TG (302 [80.32]), and low HDLc (297 [78.99]) presented normal biochemical values. There is no significative difference for male and female gender and, the social and behavior factors did not present significative association. CONCLUSION: The Fernando de Noronha presents lower prevalence of MetS thus, shows associations for elderly people. The waist circumference was elevated on female population. The results of this study provide further evidence and underscore the need for public health strategies that include education about MetS, promotion of cardiometabolic health, and prevention of undesirable outcomes such as diabetes and cardiovascular disease.
