To elevate the resistance to corrosion of magnesium alloys, silicon and zinc were simultaneously coated on the surface of AZ31 magnesium alloy using magnetron sputtering. The corrosion characteristics of the coated and uncoated samples were evaluated using electrochemical tests. Additionally, the antibacterial activity against Escherichia coli pathogens was assessed through the agar diffusion method. Compared to the AZ31 substrate and the sequentially sputtered Si and Zn coated samples, the Si-Zn composite coating specimens exhibited the minimal corrosion current density, and elevated charge impedance modulus (Z), transfer resistance (Rct), and phase angle. The simultaneous sputtering of Si-Zn composite coatings significantly slowed down the transmission of corrosive ions to the magnesium alloy surface, markedly enhancing the resistance to corrosion of magnesium alloy in SBF solution. Furthermore, the antibacterial activity of the simultaneously sputtered Si-Zn composite coating samples was superior to that of the AZ31 matrix. Therefore, the Si-Zn composite coating prepared by simultaneous sputtering possesses excellent corrosion resistance and antimicrobial properties.

Sialyllactose (SL) is a functional human milk oligosaccharide essential for immune support, brain development, intestinal maturation, and antiviral defense. However, despite its established health benefits, the effect of SL on exercise performance and muscle mass in mice remains unknown. Here, we aimed to investigate, for the first time, the effects of 6′-SL on muscle functions. Seven-week-old male C57BL/6J mice were administered 100 mg/kg 6′-SL for 12 weeks, after which exhaustive treadmill performance was conducted. Moreover, muscle strength was examined by grip strength, and muscle phenotype characteristics such as muscle mass, muscle fiber size, and muscle protein expression were also examined. The administration of 6′-SL significantly improved exhaustive treadmill performance metrics, including distance and exhaustion time. Grip strength was also increased by 6′-SL administration. Additionally, 6′-SL increased muscle mass in both the gastrocnemius (GAS) and soleus. 6′-SL administration led to an increase in the minimum Feret’s diameter and the protein expression of total myosin heavy chain in the GAS muscle. In conclusion, 6′-SL administration in vivo led to increased running distance and time by increasing muscle mass and strength. These findings collectively indicate that 6′-SL is a potential agent for improving muscle health and exercise performance.
