Targeting Skin Aging Hallmarks In Vitro: Antioxidant, Anti-Inflammatory, and An...
Marques, Mário Pedro; Landim, Euclides; Varela, Carla; Costa, Ricardo M. F. da; Marques, Joana; Carvalho, Luís A. E. Batista de; Silva, AnaPlant-based extracts are rich sources of phenolic compounds, which may act as skin antiaging mediators. Herein, Cistus albidus L. (Ca), Cistus ladanifer L. subsp. ladanifer (Cl) and Cistus salviifolius L. (Cs) were selected to test whether their phytochemical profile and bioactive potential align to target human skin aging. Hydroethanolic extracts (HEs) were prepared and characterized using infrared vibrational...

Marques, Mário Pedro; Landim, Euclides; Varela, Carla; Costa, Ricardo M. F. da; Marques, Joana; Carvalho, Luís A. E. Batista de; Silva, AnaPlants inhabiting mediterranean-influenced climatic zones, like Helichrysum stoechas (L.) Moench subsp. stoechas, Lavandula pedunculata (Mill.) Cav., and Thymus mastichina (L.) L. subsp. mastichina, have been scarcely investigated regarding their richness in phenolic compounds, herein explored as sources of skin anti-aging compounds. In this investigation, Fourier transform infrared spectroscopy (FTIR) in atten...

Acrocomia aculeata associated with doxorubicin: cardioprotection and anticancer...
Monteiro-Alfredo, Tamaeh; Dos Santos, Jéssica Maurino; Antunes, Kátia Ávila; Cunha, Janielle; da Silva Baldivia, Debora; Pires, Ana SaloméDoxorubicin (Dox) is a chemotherapeutic agent widely used in the clinic, whose side effects include cardiotoxicity, associated with decreased antioxidant defenses and increased oxidative stress. The association of Dox with natural antioxidants can extend its use if not interfering with its pharmacological potential. In this study, we aimed to understand the effects and mechanisms of the aqueous extract of Acroc...
