(Korean ginseng) is renowned for its health-promoting properties, attributed to its bioactive compounds, including saponins, polyphenols, and polysaccharides, which possess both antioxidant and anti-aging activities. This study investigated the anti-aging and anti-inflammatory effects of compounds isolated from the hot water extract of fresh roots, evaluating their resistance to TNF-α/IFN-γ-induced skin cell damage. Among 14 compounds, ginsenoside Rf (compound ) showed significant multi-target effects. In NHDFs, ginsenoside Rf and others effectively reduced intracellular ROS, demonstrating strong antioxidant properties. Additionally, they inhibited MMP-1 expression, a key enzyme in collagen degradation, and promoted pro-collagen Type I synthesis, countering the negative effects of TNF-α and supporting skin health. Further analysis showed that ginsenoside Rf reduced the secretion of inflammatory cytokines like IL-1β and IL-6, exhibiting anti-inflammatory effects. It also promoted the expression of crucial skin barrier proteins, including LOR, AQP3, FLG, and KRT1 in TNF-α/IFN-γ-stimulated NHEKs, enhancing skin hydration and structural integrity. These results suggest that compounds from roots, especially ginsenoside Rf, hold promise as skincare agents targeting skin aging and inflammation. Future research should further explore their mechanisms and optimize their applications in dermatological treatments.

Pomegranate (Punica granatum) is a widely cultivated fruit historically recognized for its health benefits and is regarded as a nutritional powerhouse. Pomegranate has a unique composition of bioactive compounds including hydrolysable tannins, anthocyanins, and other polyphenolic components. Of those, punicalagin and its subsequent metabolites are the most extensively studied, demonstrating antioxidant, anti-inflammatory, anti-cancer, and anti-nociceptive activity.

Bufalin, which is isolated from toad venom, exerts positive effects on hearts under pathological circumstance. We aimed to investigate the effects and mechanisms of bufalin on myocardial I/R injury. In vivo, bufalin ameliorated myocardial I/R injury, which characteristics with better ejection function, decreased infarct size and less apoptosis.

Blood storage lesion induces cytosolic and membrane changes driven in part by hemoglobin (Hb) oxidation reactions within red blood cells (RBCs). A novel gel formulation containing the antioxidant curcuminoids in a biocompatible solvent system was used to deliver curcumin into RBCs. Incubation of peroxide treated RBCs stored in PBS with curcumin gel led to a reduction in prooxidant ferrylHb and recovery in ATP.

LAG3 plays a regulatory role in immunity and emerged as an inhibitory immune checkpoint molecule comparable to PD-L1 and CTLA-4 and a potential target for enhancing anti-cancer immune responses. We generated 3D cancer cultures as a model to identify novel molecular biomarkers for the selection of patients suitable for α-LAG3 treatment and simultaneously the possibility to perform an early diagnosis due to its higher presence in breast cancer, also to achieve a theragnostic approach. Our data confirm the extreme dysregulation of LAG3 in breast cancer with significantly higher expression in tumor tissue specimens, compared to non-cancerous tissue controls.

Resolvin D1 (RvD1) is an endogenous anti-inflammatory mediator that modulates the inflammatory response and promotes inflammation resolution. RvD1 has demonstrated neuroprotective effects in various central nervous system contexts; however, its role in the pathophysiological processes of intracerebral hemorrhage (ICH) and the potential protective mechanisms when combined with exercise rehabilitation remain unclear. A mouse model of ICH was established using collagenase, and treatment with RvD1 combined with three weeks of exercise rehabilitation significantly improved neurological deficits, muscle strength, learning, and memory in ICH mice while reducing anxiety-like behavior.
