Advances in the phytochemical screening and biological potential of propolis.

Propolis is a natural resinous product collected from different parts of plants by bees and mixed with their salivary secretions. The occurrence of more than 180 different chemotypes has flavonoids, phenolic acids, esters, and phenolic aldehydes, as well as balsamic resins, beeswax, pollen, and essential and aromatic oils, among others. Its biological potential documented throughout the world justifies the need, from time to time, to organize reviews on the subject, with the intention of gathering and informing about the update on propolis.

Effects of Acetylsalicylic Acid Usage on Inflammatory and Oxidative Stress Markers in Hemodialysis Patients.

The aims of this study were to determine the effects of acetylsalicylic acid (ASA) on inflammation and oxidative stress markers in hemodialysis (HD) patients and to examine the associations between these markers and the sociodemographic and clinical characteristics of participants. The study included 36 subjects who used 300 mg of ASA for 60 days. Inflammation and oxidative stress were assessed based on levels of biochemical markers.
