RESUMO

This study aimed to conduct a comparative analysis of germinated seeds and microgreens derived from Perilla frutescens var. crispa f. viridis, hypothesizing that microgreens would exhibit higher concentrations of nutrients and bioactive compounds compared to their precursors. Perilla frutescens was chosen for its popularity and wide use in Asian cuisine. A series of analytical methods was employed to quantify and qualify various components. The findings indicate that germinated seeds exhibit significantly higher quantities of lipids, proteins, sugars, free amino acids, and minerals, whereas microgreens possess significantly high concentration of vitamins and polyphenols. These results provide valuable insights into the nutritional differences between germinated seeds and microgreens, highlighting their distinct contributions to diet. Specifically, incorporating germinated seeds can enhance macronutrient intake, while microgreens can boost antioxidant intake. These findings can inform the development of targeted dietary recommendations, promoting the inclusion of both germinated seeds and microgreens to meet specific nutritional needs and improve health outcomes.

RESUMO

Turmeric (Curcuma longa) contains various compounds that potentially improve health. Bisacurone is a turmeric-derived compound but has been less studied compared to other compounds, such as curcumin. In this study, we aimed to evaluate the anti-inflammatory and lipid-lowering effects of bisacurone in high-fat diet (HFD)-fed mice. Mice were fed HFD to induce lipidemia and orally administered bisacurone daily for two weeks. Bisacurone reduced liver weight, serum cholesterol and triglyceride levels, and blood viscosity in mice. Splenocytes from bisacurone-treated mice produced lower levels of the pro-inflammatory cytokines IL-6 and TNF-α upon stimulation with a toll-like receptor (TLR) 4 ligand, lipopolysaccharide (LPS), and TLR1/2 ligand, Pam3CSK4, than those from untreated mice. Bisacurone also inhibited LPS-induced IL-6 and TNF-α production in the murine macrophage cell line, RAW264.7. Western blot analysis revealed that bisacurone inhibited the phosphorylation of IKKα/ß and NF-κB p65 subunit, but not of the mitogen-activated protein kinases, p38 kinase and p42/44 kinases, and c-Jun N-terminal kinase in the cells. Collectively, these results suggest that bisacurone has the potential to reduce serum lipid levels and blood viscosity in mice with high-fat diet-induced lipidemia and modulate inflammation via inhibition of NF-κB-mediated pathways.

RESUMO

The rapid development of aberrant cells outgrowing their normal bounds, which can subsequently infect other body parts and spread to other organs-a process known as metastasis-is one of the significant characteristics of cancer. The main reason why cancer patients die is because of widespread metastases. This abnormal cell proliferation varies in cancers of over a hundred types, and their response to treatment can vary substantially. Several anti-cancer drugs have been discovered to treat various tumors, yet they still have harmful side-effects. Finding novel, highly efficient targeted therapies based on modifications in the molecular biology of tumor cells is essential to reduce the indiscriminate destruction of healthy cells. Exosomes, an extracellular vesicle, are promising as a drug carrier for cancer therapy due to their good tolerance in the body. In addition, the tumor microenvironment is a potential target to regulate in cancer treatment. Therefore, macrophages are polarized toward M1 and M2 phenotypes, which are involved in cancer proliferation and are malignant. It is evident from recent studies that controlled macrophage polarization might contribute to cancer treatment, by the direct way of using miRNA. This review provides an insight into the potential use of exosomes to develop an 'indirect', more natural, and harmless cancer treatment through regulating macrophage polarization.

RESUMO

3-(4-hydroxy-3-methoxyphenyl)propionic acid (HMPA) is one of the end-products from gut microbiota from dietary polyphenols, which might contribute to their health benefits. This study aims to investigate the absorption, metabolism, and tissue accumulation of HMPA in Sprague-Dawley (SD) rats. After HMPA (10 mg/kg body weight) was orally administered, intact and conjugated HMPAs in the bloodstream were detected and reached the maximum concentration in 15 min (HMPA, 2.6 ± 0.4 nmol/mL; sulfated HMPA, 3.6 ± 0.9 nmol/mL; glucuronidated HMPA, 0.55 ± 0.09 nmol/mL). HMPA and its conjugates were also detected in the target organs 6 h postadministration, indicating that HMPA undergoes rapid conversion into conjugates, and they broadly distribute to organs with similar profiles (kidneys > liver > thoracic aorta > heart > soleus muscle > lungs). This study demonstrated that orally administered HMPA (10 mg/kg) in SD rats undergoes rapid metabolism and wide tissue distribution with ≥1.2% absorption ratio.

RESUMO

Iron is the most abundant mineral in the human body and plays essential roles in sustaining life, such as the transport of oxygen to systemic organs. The Fenton reaction is the reaction between iron and hydrogen peroxide, generating hydroxyl radical, which is highly reactive and highly toxic to living cells. "Ferroptosis", a programmed cell death in which the Fenton reaction is closely involved, has recently received much attention. Furthermore, various applications of the Fenton reaction have been reported in the medical and nutritional fields, such as cancer treatment or sterilization. Here, this review summarizes the recent growing interest in the usefulness of iron and its biological relevance through basic and practical information of the Fenton reaction and recent reports.
