X-ray interpretation of Dog

medical illustration of This molecular illustration shows the steps involved in building the ‘membrane-attack complex’ (MAC) during an immune response against an invading bacterium. A transmembrane channel is formed when up to 16 C9 molecules are added, thus disrupting the outer membrane (the complete pore was halved for the sake of the illustration).
Next medical illustration of This is an image of conotoxin and an inset of how it affects a voltage-gated calcium channel (VGCC). Conotoxin is a peptide toxin created by a tropical marine snail (Conus victoriae). Aside from VGCCs, the toxin also targets voltage-gated sodium channels, voltage-gated potassium channels, and nicotinic acetylcholine receptors. Conotoxins are being explored as an option for pain-relief therapy.
