Several natural products have been investigated for their bactericidal potential, among these, cinnamaldehyde. In this study, we aimed to evaluate the activity of cinnamaldehyde in the treatment of animals with sepsis induced by extraintestinal pathogenic . Initially, the F5 was incubated with cinnamaldehyde to evaluate the minimum inhibitory and minimum bactericidal concentration.

The hydroalcoholic extract and ethyl acetate fraction of leaves have been known to exhibit anti-inflammatory activities. In this study, we investigated the therapeutic effects of galloyl-hexahydroxydiphenoyl (HHDP)-glucose isolated from pomegranate leaves on lipopolysaccharide (LPS)-induced acute lung injury (ALI) in mice. Male BALB/c mice were treated with different doses of galloyl-HHDP-glucose (5, 50, and 100 mg/Kg) or dexamethasone at 5 mg/Kg () 6 h after intra-tracheal instillation of LPS.

Despite their demonstrated biocompatibility and osteogenic properties, oyster shells have been reported as a potential alternative to other commonly used materials for bone substitution. This study evaluated whether an experimental bone substitute (EBS) made from a typical oyster shell of Northeastern Brazil (Crassostrea rhizophora) has effects on bone development using an animal model. Oysters were collected from a biologically assisted vivarium, and their inner layer was used for preparing an EBS.

Rheumatoid arthritis (RA) is characterized by inflammation of one or more joints, and affects ~1% of the adult population worldwide. Sulforaphane (SFN) is a natural compound that has been suggested as an antioxidant. Here, SFN’s effects were evaluated in a murine mono-arthritis model.

Article Synopsis
  • The study examines the anti-inflammatory effects of the ethyl acetate fraction from pomegranate leaves (EAFPg) on acute lung injury (ALI) induced by lipopolysaccharide (LPS) in a mouse model.
  • Male Swiss mice were treated with varying doses of EAFPg or dexamethasone before LPS exposure, and results showed that EAFPg significantly reduced neutrophil accumulation and collagen deposition in the lungs.
  • Additionally, EAFPg and kaempferol decreased nitric oxide production and cytokine expression in cultured macrophages, indicating potential therapeutic value for EAFPg in treating lung inflammation.

The absence of an effective vaccine and the debilitating chemotherapy for Leishmaniasis demonstrate the need for developing alternative treatments. Several studies conducted with Morinda citrifolia have shown various biological activities, including antileishmanial activity, however its mechanisms of action are unknown. This study aimed to analyze the in vivo activity of M.
