Abstract Gold nanoparticles (AuNPs) have unique features that might lead to the development of a new class diabetic medicines. AuNPs were biosynthesized utilizing sodium-alginate. UV-Vis-spectroscopy, Fourier transforms infrared, field emission scanning electron microscopy (FESEM), and energy dispersive X-ray used examine particles. The potential for improving diabetes condition was examined along with swimming in rats. FESEM image revealed spherical morphology an average particle size 106.6 ± 20.8 nm. In group, serum glucose, blood urea nitrogen (BUN), creatinine, cholesterol, triglyceride (TG) levels significantly higher than control group. Low-density lipoprotein (LDL) high-density (HDL) lower group compared Malondialdehyde (MDA) also D However, groups treated gold, these parameters improved. Specifically, serum-glucose, BUN, TG reduced, while LDL decreased + HDL increased MDA groups, other antioxidants improved Catalase gold It can be concluded both decrease complications.

In recent years, the frequency of strokes has been on rise year by and become second leading cause death around world, which is characterized a high mortality rate, recurrence disability rate. Ischemic account for large percentage strokes. A reperfusion injury in ischemic complex cascade oxidative stress, neuroinflammation, immune infiltration, mitochondrial damage. Conventional treatments are ineffective, presence blood–brain barrier (BBB) leads to inefficient drug delivery utilization, so researchers turning their attention nano-drug systems. Functionalized systems have widely studied applied study cerebral diseases due favorable biocompatibility, efficiency, strong specificity, specific targeting ability. this paper, we briefly describe pathological process injuries focus therapeutic research progress strokes, aiming provide certain references understand (NDDSs).

Background: Liver cancer is increasing in different parts of the world and fourth leading cause death globally. Objectives: The present study aims to synthesize analyze characterization gold nanoparticles (AuNPs) synthesized by Cichorium intybus extract evaluate their antioxidant cellular toxicity activity against liver cells (HepG2). Methods: AuNPs were characterized using X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), fourier-transform infrared spectroscopy (FTIR). was assessed DPPH test, cytotoxicity analyzed MTT method. Results: results indicate that are crystalline materials with a particle size less than 100 nm, mean 23.94 nm. FTIR reveals presence biochemical groups act as reducing factors. demonstrate increases concentration, 87% inhibition free radical scavenging observed at 250 µg/mL. Cell cell lines (HepG2) demonstrated significant time- dose-dependent manner. percentage viability concentration 1000 µg/ml after 24, 48, 72 hours determined be 45%, 51%, 22%, respectively.
