Intestinal Permeability (Leaky Gut): Measuring markers like zonulin that indicate a compromised gut lining
[36, 37] Unlike conventional hypodermic needles, microneedle systems create transient microchannels that bypass the stratum corneum, enabling efficient transdermal transport of a wide range of molecules, including peptides, proteins, and small drugs, without reaching nerve-rich deeper layers and thus minimizing pain and risk of infection [38, 39]
Dosages are usually in micrograms (mcg), milliliters (mL), or milligrams (mg)
Activation of the caspase cascade system, such as caspase-3, caspase-8, caspase-9, and poly (ADP-ribose) polymerase, and the increased level of P53, ROS, and the ratio of Bax/Bcl-2 contribute to loss of MMP in epithelial cells (66)
