Porphyrin Production by Corynebacterium diphtheriae Strains from Clinical Isolates.

Porphyrins are intermediate metabolites involved in the biosynthesis of vital molecules, including heme, cobalamin, and chlorophyll. Bacterial porphyrins are known to be proinflammatory and are associated with biofilm formation. This study investigated porphyrin production by strains of Corynebacterium diphtheriae using emission spectroscopy, high-performance liquid chromatography with fluorescence detection, diode array detector, and mass spectrometry.

Chemical Composition, Fatty Acid Profile, Phenolic Compounds, and Antioxidant Activity of Raw and Germinated Chia (Salvia hispanica L.) Seeds.

The consumption of chia seeds has become popular due to their beneficial health properties and the germination of chia seeds seems to further enhance these properties. This study aimed to evaluate the changes in the nutritional composition of chia seeds after germination for 3 and 6 days. Chemical composition, fatty acid profile, phenolic content and antioxidant capacity were determined.

fraction with a high level of flavonoid inhibits peripheral and central mechanisms of nociception.

Background And Aim: (Kunth.) Micheli is popularly used for acute and chronic inflammatory conditions. The anti-inflammatory activity was previously demonstrated for its flavonoid-enriched fractions.

Echinodorus macrophyllus: Hydroxycinnamoyl derivatives reduces neutrophil migration through modulation of cytokines, chemokines, and prostaglandin in the air-pouch model.

Ethnopharmacological Relevance: In Brazil, Echinodorus macrophyllus (Alismataceae), popularly known as chapéu-de-couro, is used to treat inflammatory diseases. Previous studies have shown a significant decrease in the acute inflammation for the aqueous extract of E. macrophyllus (AEEm) and its ethanolic fraction (Fr20).

Flavonoid-enriched fraction from Echinodorus macrophyllus aqueous extract exhibits high in-vitro and in-vivo anti-inflammatory activity.

Objectives: Echinodorus macrophyllus (Kunth) Micheli (Alismataceae) is popularly used as an infusion to treat inflammatory diseases. This work fractionated the aqueous extract of E. macrophyllus (AEEm) to improve its anti-inflammatory effects.
